1 1999-08-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3 * eval.c (SCM_APPLY), sort.c (closureless): Expand body when
6 1999-08-18 Gary Houston <ghouston@easynet.co.uk>
8 * fports.c (fport_write): use memcpy instead of strncpy, in case
11 1999-08-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
13 * gh.h (gh_vector_to_list): Bugfix. (Thanks to Frank Cieslok.)
15 * backtrace.c, debug.c, eval.c, eval.h, gsubr.c, procprop.h,
16 read.c, srcprop.c, srcprop.h (scm_i_filename, scm_i_line,
17 scm_i_column, scm_i_copy, scm_i_name, scm_i_lambda, scm_i_source,
18 scm_i_more, scm_i_procname, scm_i_dot, scm_i_arrow, scm_i_else,
19 scm_i_unquote, scm_i_uq_splicing, scm_i_apply, scm_i_enter_frame,
20 scm_i_apply_frame, scm_i_exit_frame, scm_i_trace, scm_i_quote,
21 scm_i_begin, scm_i_if, scm_i_and, scm_i_or, scm_i_case,
22 scm_i_cond, scm_i_letstar, scm_i_do, scm_i_quasiquote,
23 scm_i_define, scm_i_letrec, scm_i_let, scm_i_atapply,
24 scm_i_atcall_cc, scm_i_breakpoint): Renamed: Consequently use
25 scm_sym_ as prefix for symbols.
27 * debug.c (scm_i_proc, scm_i_args, scm_i_eval_args): Removed.
29 * eval.c, eval.h (scm_sym_begin, scm_sym_if, scm_sym_and,
30 scm_sym_case, scm_sym_cond, scm_sym_letstar, scm_sym_do,
31 scm_sym_define, scm_sym_letrec, scm_sym_atapply,
32 scm_sym_atcall_cc): Made global.
34 1999-08-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
36 * eval.c (scm_sym_args): Made global.
38 * objects.c (scm_set_object_procedure_x): Disallow setting of
39 procedures for pure generic functions.
41 1999-08-12 Gary Houston <ghouston@easynet.co.uk>
43 * ports.c (scm_seek): one more: was scm_lseek. Also changed the
44 Scheme name from lseek to seek, but lseek was added recently so
45 it shouldn't be a big problem.
46 * ports.c, gdbint.c, ioext.c: changed callers.
48 1999-08-11 Gary Houston <ghouston@easynet.co.uk>
50 * fports.c (fport_input_waiting): if select is used, return 1
51 instead of whatever FD_ISSET expands to. maybe it will be useful
52 to interpret the value from the input_waiting ptob procedure as a
53 lower bound on the number of bytes available.
55 * Mikael asked for a few names to be changed...
57 * ports.c (scm_make_port_type): take the write procedure as the
58 second argument instead of the flush procedure.
59 * ports.h (scm_ptob_descriptor): rename the ptob procedures:
60 fflush -> flush, read_flush -> end_input, fclose -> close,
61 fill_buffer -> fill_input, ftruncate -> truncate,
62 input_waiting_p -> input_waiting.
64 * ports.c (end_input_void_port): was read_flush_void_port.
65 (scm_set_port_end_input): was scm_set_port_flush_input.
66 (scm_set_port_flush): was scm_set_port_write.
67 (scm_set_port_input_waiting): was scm_set_port_input_waiting_p
68 (scm_end_input): was scm_read_flush.
69 (scm_fill_input): was scm_fill_buffer.
70 (scm_flush): was scm_fflush.
71 * fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
72 (fport_end_input): was local_read_flush.
73 (fport_flush): was local_fflush.
74 (fport_close): was local_fclose.
75 (fport_truncate): was local_ftruncate.
76 (fport_seek): was local_seek.
77 (fport_free): was local_free.
78 (fport_fill_input): was fport_fill_buffer.
79 * strports.c (st_end_input): was st_read_flush.
80 (st_truncate): was st_ftruncate.
81 * vports.c: (sf_flush): was sfflush.
82 (sf_close): was sfclose.
83 (sf_fill_input): was sf_fill_buffer.
85 * ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c:
88 1999-08-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
90 * eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol. Dispatch
91 forms now contain the expressions to be dispatched upon instead of
92 depending on a surrounding lambda or let; Generic function
93 dispatch has been optimized; `apply' on a generic function now
94 works a little bit strangely. It uses a trick so that the type
95 dispatch code in SCM_CEVAL can be reused.
97 * objects.h, objects.c (scm_apply_generic_env): Added (used by
99 (scm_operator_p): Added.
100 (scm_sym_atdispatch): Added.
101 (scm_set_object_procedure_x): Modified to handle the new style
103 (scm_object_procedures): New debugging procedure.
105 1999-08-05 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
107 * eval.c, eval.h (scm_sym_args): Added.
109 * objects.h (SCM_CLASSF_PURE_GENERIC): Added.
111 * feature.c, feature.h (scm_c_run_hook): Added.
113 * eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to
114 cdrxnoap and loopnoap instead of begin and loop.
116 1999-08-04 Gary Houston <ghouston@easynet.co.uk>
118 * ports.c (scm_putc, scm_puts),
119 * unif.c (scm_uniform_array_write): use scm_lfwrite.
120 * ports.c (scm_putc): change type of first argument from int to char.
122 1999-08-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
124 * eval.c (SCM_CEVAL): Improvements to SCM_IM_DISPATCH and
125 SCM_IM_HASH_DISPATCH.
127 * objects.h (SCM_CLASSF_GOOPS_VALID): Added.
128 (scm_si_redfined, scm_si_hashsets): Moved.
130 * objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID
131 flag which combines type and status info so that the class
132 redefinition protocol has zero cost during normal execution.
134 1999-08-03 Gary Houston <ghouston@easynet.co.uk>
136 * ports.h (scm_ptob_descriptor): include a write procedure again.
137 it's more efficient for unbuffered fports (e.g., sockets.)
139 * ports.c (scm_puts): use ptob->write.
140 * vports.c (scm_make_sfptob): set write proc in ptob.
141 * strports.c (scm_make_stptob): set write proc in ptob.
142 * ports.c (write_void_port): new procedure.
143 * vports.c (sf_write): new procedure.
144 * ports.c (scm_lfwrite): use ptob->write.
145 * strports.c (st_write): new procedure.
146 * fports.c (fport_write): new procedure.
147 (scm_make_fptob): set write in ptob to fport_write.
148 * ports.h: prototype for scm_set_port_write.
149 * ports.c (scm_make_port_type): initialise ptob write procedure.
150 (scm_set_port_write): new proc.
152 1999-08-01 Jim Blandy <jimb@savonarola.red-bean.com>
154 * ports.c (scm_char_ready_p): Don't try to find PORT's ptab entry
155 until we've verified that it is actually a port. (Thanks to
158 1999-07-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
160 * gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary
161 code, particularly an unnecessary test (len != size, where len ==
162 size). (Was this leftovers from debugging code, or have I missed
165 * hashtab.c: Bugfix: Don't declare s_hash_fold without storage
166 size. (Thanks to James Dean Palmer.)
168 * numbers.c (scm_makdbl): Bugfix: Initialize imaginary part.
169 (Thanks to Lorentey Karoly.)
171 1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
173 * eval.c (scm_m_expand_body): Use scm_cons_source.
175 * struct.c (scm_print_struct): Use vtable name.
177 * print.c (scm_init_print): Set name of print state type.
179 * stacks.c (scm_init_stacks): Set name of stack type.
181 1999-07-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
183 * eval.c (SCM_CEVAL): Removed old implementation of internal
186 * gsubr.c, procprop.h (scm_i_inner_name): Removed.
188 * debug.c, debug.h (scm_reverse_lookup): Added.
189 (scm_procedure_name): Use scm_reverse_lookup to lookup the name of
190 internal procedure definitions; Don't use scm_i_inner_name.
192 * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
195 * eval.h: Added prototypes for multi language support functions.
197 * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
198 improper lists in the low-level representation, since that will
199 cause a begin to be prepended at macro expansion.
201 * eval.c (scm_cons_source): Version of cons which copies source
202 properties from an existing cell.
203 (scm_copy_tree, SCM_CEVAL): Use scm_cons_source.
205 * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
206 procedure source before calling scm_unmemocopy instead of faking
209 1998-10-25 Marius Vollmer <mvo@zagadka.ping.de>
211 Ported `internal defines' fix from SCM. Original ChangeLog entry:
213 1998-07-09 Radey Shouman <radey@colorage.com>
215 * eval.c (ceval_1): Modifications to allow rewriting of interal
216 DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
217 body of which it is the CAR is macro expanded by m_expand_body,
218 which rewrites internal DEFINE.
220 (m_expand_body): Added.
222 (m_macroexp1): Added argument to control error checking:
223 m_expand_body may speculatively expand forms in the wrong
224 environments. Made argument number checks conditional on
227 (m_body): Added, error checks bodies and inserts the ISYM tokens.
229 (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
232 (m_cond): (m_case): (m_quote): Modified to avoid destructively
233 changing their argument forms. Since m_expand_body
234 speculatively macro expands forms the process must be
237 (m_ident_eqp): Fixed to use proper environment.
239 (renamed_ident): Added DEFER_INTS_EGC.
241 Added prototypes for static functions.
247 (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK
248 is false, do not produce an error for unbound variables, return a
249 pointer to cell_undef instead.
251 (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.
255 (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
256 destructively changing their argument forms. Since m_expand_body
257 speculatively macro expands forms the process must be reversible.
259 (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for
260 SCM_IM_LET introduced by named lets.
262 (scm_m_letstar): Use scm_m_body instead of bodycheck.
264 (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
265 scm_letrec. scm_letrec1 does not check for a null binding and
266 takes an additional argument to specify the ISYM of the body. Use
267 scm_m_body instead of bodycheck.
269 (scm_m_let): Use scm_m_body instead of bodycheck.
271 (scm_m_expand_body, scm_macroexp): New.
273 (unmemocopy): Account for ISYMs introduced by scm_m_body.
275 (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with
276 check=1. Throw error for internal defined that have not been
277 rewritten by scm_m_expand_body.
279 * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
280 Removed prototype for SCM_APPLY.
282 * tags.h: Added extern declaration of scm_isymnames.
284 1999-07-27 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
286 * Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c.
288 * lang.c: New file: Beginning of multi-language support.
290 * init.c (scm_boot_guile_1): Added call to scm_init_lang ().
292 * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
293 (scm_dynamic_wind): Added argument checking for the after guard so
294 that we don't add garbage on the dynwind chain.
295 (scm_swap_bindings): Added.
297 * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
298 SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
299 (scm_isymnames): New isyms for multi-language support.
301 * eval.c (scm_nil, scm_t): New symbols.
302 (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special
303 forms for multi-language support.
305 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
307 * random.c, random.h (scm_c_default_rstate, scm_c_uniform32):
309 Renamed functions in the random function library interface
310 from scm_i_XXX --> scm_c_XXX.
312 1999-07-25 Gary Houston <ghouston@easynet.co.uk>
314 * ports.c (scm_putc): fix line-buffering.
316 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
318 * ports.c, ports.h, fports.c, strports.c, vports.c: Renamed
319 scm_set_ptob_XXX --> scm_set_port_XXX.
321 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
323 * ports.c, ports.h (scm_make_port_type): New interface for
324 creation of port types (replaces scm_newptob). Just as for the
325 smobs, we need to separate the internal representation of smob
326 types from the interface, so that we easily can add new fields and
327 rearrange things without caring about backward compatibility.
328 This change was forced by the need in GOOPS to create classes
329 representing port types.
330 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
331 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,
332 scm_set_ptob_seek, scm_set_ptob_truncate,
333 scm_set_ptob_input_waiting_p): New setters.
334 (scm_newptob): Rewritten to use scm_make_port_type. For backward
336 (scm_ptobs): Changed type scm_ptobfuns --> scm_ptob_descriptor.
337 (scm_prinport): Removed.
338 (scm_port_print): Added.
339 (scm_print_port_mode): Added.
340 (void_port_ptob, print_void_port, close_void_port, noop0):
341 Removed. Removed #include "genio.h" Added #include "objects.h",
344 * fports.c (prinfport): Moved code from ports.c.
346 (scm_fptob): Removed. Instead use new interface.
347 (scm_make_fptob): Added. (Need to create basic ports in a
348 specific order in ports.c.)
350 * strports.c (scm_stptob, prinstpt, noop0): Removed
351 (scm_make_stptob): Added.
353 * vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed.
354 (scm_make_sfport): Added.
356 * filesys.c (scm_dir_print): Don't use the port printing code.
357 Instead provide specific directory printer.
359 * gc.c (scm_gc_sweep): Use value returned from scm_ptobs[].free.
361 * ioext.c (scm_redirect_port): Replaced scm_ptobfuns -->
364 * smob.c (scm_smob_print): Handle non-existing type name nicely.
365 Removed #include "genio.h"
367 * objects.c (scm_make_port_classes): New function ptr.
369 1999-07-24 Gary Houston <ghouston@easynet.co.uk>
371 * gdbint.c (gdb_print, gdb_read): call scm_truncate_file.
373 * ports.c (scm_truncate_file): renamed from scm_ftruncate.
374 allow the 1st argument to be a fdes or filename as well as a
375 port (as in the filesys.c version).
377 * filesys.c (scm_truncate_file): removed.
379 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
381 * readline.c, readline.h: Removed.
383 * objects.c, objects.h (scm_port_class): Added.
384 (scm_class_of): Look up port class in scm_port_class.
385 (SCM_IN_PCLASS_INDEX, SCM_OUT_PCLASS_INDEX,
386 SCM_INOUT_PCLASS_INDEX): Added.
389 * Makefile.am: Removed genio.c, genio.x.
393 1999-07-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
395 * init.c: Make sure that scm_post_boot_init_modules is called only
396 once. (Important when using a dumped image.; Thanks to Bernard
399 1999-07-19 Jim Blandy <jimb@savonarola.red-bean.com>
401 * guardians.c (scm_guardian_zombify): Separate scanning for
402 zombies from marking the pairs of the free list.
404 * guardians.c (scm_guardian_zombify): Don't set marks manually ---
405 use the macros. (Thanks to Michael Livshin.)
407 * eval.c (scm_m_lambda): Let bodycheck check the body of the
408 lambda. Let your sins be purified by the blood of the lambda.
409 (Thanks to Eric Hanchrow.)
411 * net_db.c (h_errno): Don't declare this if it's #defined. Eew.
412 (Thanks to Valdis Kletnieks.)
414 Fixes for EMX from Mikael Ståldal.
416 * filesys.c: #include <io.h>, if we have it.
417 * scmconfig.h.in: Regenerated.
419 * stime.c (ftime): Delete declaration for this function --- let
420 the system supply it.
422 Cleanups from John Bley.
424 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
426 * gsubr.c: Don't include "gsubr.h" twice.
428 Cleanups for compilation on Irix 6, from David Kaelbling.
430 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to
431 regex_t pointer. This is what the callers have, mostly.
432 (scm_regexp_exec): Don't forget to pass the `rx' argument to
433 scm_regexp_error_msg.
435 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
436 int. That way, if we get a warning on this line, it's more likely
437 that we're really missing bits we care about.
439 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
442 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
443 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
444 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
445 cast at all is more appropriate in every case. At the moment, we
446 assume everywhere that SCM is an integral type anyway.
448 1999-07-14 Gary Houston <ghouston@easynet.co.uk>
450 * unif.c (scm_uniform_array_read_x), ports.c (scm_getc): increment
451 read_pos after scm_fill_buffer.
453 * ioext.c (scm_do_read_line): simplify by ignoring the fill_buffer
456 * vports.c (sf_fill_buffer), strports.c (stfill_buffer),
457 fports.c (fport_fill_buffer): implement the interface change.
459 * ports.c (scm_fill_buffer): interface change: no longer increments
460 read_pos past the character that's returned. it seems clearer to
461 leave it to the caller to decide what to do (thanks Jim).
463 * vports.c (sf_fill_buffer): put the read char into the buffer
464 as well as returning it.
466 * ports.c (scm_grow_port_cbuf): residue of this deleted procedure
469 1999-07-13 Gary Houston <ghouston@easynet.co.uk>
471 * strports.c (scm_strprint_obj): simplify. start with initial
473 (st_seek): don't allow string to be extended if seeking past
474 the end of a read-only port.
476 1999-07-12 Gary Houston <ghouston@easynet.co.uk>
478 * strports.c (st_seek): change the resize checks.
480 * ports.c (scm_ftruncate): throw error if offset works out negative.
482 * strports.c (st_flush): increase string size in blocks of
483 SCM_WRITE_BLOCK instead of 1. set read_end to read_pos if
484 it's greater and reset read_buf_size.
485 (scm_mkstrport): set rw_randow if only writing, since read_buf needs
486 to be maintained for output ports too (it holds the written
487 part of the string, while write_buf may have unwritten buffer
489 (st_truncate): rewritten.
490 (top of file): added a few notes.
492 1999-07-10 Jim Blandy <jimb@savonarola.red-bean.com>
494 Patch from Greg Badros:
495 * snarf.h (SCM_PROC, SCM_PROC1): Use __cplusplus or
496 GUILE_CPLUSPLUS_SNARF macros to force adding a cast to the last
497 (function pointer) argument to scm_make_gsubr and scm_make_subr
498 calls. This avoids warnings in C++ programs using guile-snarf.
500 1999-07-06 Gary Houston <ghouston@easynet.co.uk>
502 * strports.c (st_grow_port): set pt->read_pos. set
503 pt->read_buf_size one less than pt->write_buf_size if there's
504 an unwritten char at the end of the string. similarly for
506 (st_resize_port): renamed from st_grow_port.
507 (st_seek): simplify by assuming that pt->write_pos == pt->read_pos.
508 seek from read_end instead of write_end for SEEK_END.
509 (st_ftruncate): calculate current length using readbuf, not write
511 (scm_strport_to_string): use read_buf_size for length.
512 (stfill_buffer): don't re-initialise the readbuf.
514 1999-07-05 Gary Houston <ghouston@easynet.co.uk>
516 * strports.c (scm_strport_to_string): new procedure.
517 (scm_call_with_output_string, scm_strprint_obj): use
518 scm_strport_to_string.
519 used SCM_INUM0 instead of SCM_MAKINUM (0) in a few places.
521 1999-07-08 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
523 * symbols.c (scm_gensym): Bugfix. (Thanks to Johannes Hjorth.)
525 Fri Jun 25 22:14:32 1999 Greg Badros <gjb@cs.washington.edu>
527 * smob.c: added scm_make_smob_type_mfpe (), scm_set_smob_mfpe ();
528 use scm_make_smob_type_mfpe to initialize "free", "flo", "bigpos",
529 and "bigneg" smob types.

756 instead of stepping through an array.
757 (scm_gc_sweep): Update offset used to find start of weak vector to
759 (scm_init_storage): Set scm_weak_vectors to EOL.
761 Fix from Ken Raeburn <raeburn@raeburn.org>:
762 * gc.c (already_in_gc): New variable.

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

783 ChangeLog entries and the patch from two different places...
785 1999-06-09 Jim Blandy <jimb@savonarola.red-bean.com>
787 * gc.c (scm_igc): Check for scm_mallocated underflow. Otherwise,
788 it shows up as terrible performance, as we GC constantly.
790 * ioext.c (scm_do_read_line): Rewritten to use memchr to find the
791 newline. A bit faster, and definitely hairier.
792 (scm_read_line): Count newlines here instead.
794 * strings.c (scm_take_str): New function.
795 (scm_take0str): Reimplement in terms of scm_take_str. * strings.h

810 1999-04-26 Gary Houston <ghouston@easynet.co.uk>
812 * ports.c: (scm_lseek): clear buffers even if just reading current

836 strports.c (scm_call_with_output_string): start with an empty
837 string, so seek and ftruncate can be used.
839 gdbint.c: adjust string port usage.
841 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
843 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
844 equivalent to fflush for the read buffer.
845 * ports.c (scm_newptob): set read_flush.
846 ports.c (void_port_ptob): set read_flush.
847 fports.c (local_read_flush): new proc. add to ptob.
848 strport.c (st_read_flush): likewise.

852 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
853 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
854 ptob proc if the read buffer is filled.
856 1999-04-23 Gary Houston <ghouston@easynet.co.uk>

859 reading and writing members with rw_active member.
860 SCM_PORT_READ/SCM_PORT_WRITE: new values.
862 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
864 * ports.h (struct scm_port_table): add writing and reading members
865 to replace write_needs_seek: it isn't good enough for non-fports.

867 (struct scm_port_table): give it a typedef and rename to scm_port.
868 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
869 corresponding changes.

879 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
880 signals (it was only being done for handlers installed from Scheme).
881 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
882 waiting for input caused an EINTR error from read.
884 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
886 * ports.h (struct scm_port_table): make all the char members
887 unsigned, so they convert to int without becoming negative if large.
889 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
891 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
892 with threads enabled. rename this procedure to

894 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
896 * readline.c (scm_readline): Applied a patch from Greg Harvey to
897 get readline support working again: use fdopen to get FILE objects.
899 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
901 * gc.c (scm_init_storage): install an atexit proc to flush the
903 (cleanup): the new proc. it sets a global variable which can be
904 checked by the ptob flush procs to avoid trying to throw
905 exceptions during exit. not very pleasant but it seems more reliable.
906 * fports.c (local_fflush): check terminating variable and if set
907 don't throw exception.
908 * CHECKME: that the atexit proc is installed if unexec used.
910 * throw.c (scm_handle_by_message): don't flush all ports here.
911 it still causes bus errors.

919 ptob entry if needed.
921 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
922 ptob initialisers. use it in char-ready
924 * ioext.c (scm_do_read_line): moved from ports.c. make it static.

927 currently use shortbuf.)
929 * fports.c (scm_standard_stream_to_port): moved to init.c and
932 * init.c (scm_init_standard_ports): make stdout and stderr
933 unbuffered if connected to a terminal. with stdio they
934 were line-buffered by default.

939 * ports.h (scm_ptobfuns): change fflush return to void.
940 change flush proc definitions.

943 buffer instead of port stream.
944 (st_flush): new proc.
946 * ports.h (struct scm_port_table): added write_end member,
947 as an optimisation. set it where write_buf_size is set.
949 * ports.h (struct scm_port_table): change stream from void *
950 back to SCM. SCM presumably must be large enough to hold a
951 pointer (and probably vice versa but who knows.)
952 (SCM_SSTREAM): deleted. change users back to SCM_STREAM.
954 (scm_puts): rewritten
955 * fports.c (local_ffwrite, local_fputs): removed.

967 * ports.h (scm_ptobfuns): add seek function pointer.
968 * fports.c: set it to local_seek, new procedure.
971 * fports.h (SCM_MAYBE_DRAIN_INPUT): moved to ports.c.
972 use ptob for seek. take ptob instead of fport arg.
974 * ports.h (struct scm_port_table): new member write_needs_seek,
975 replaces reading member in fport struct.
977 * vports.c (sfgetc): store the getted char into the buffer.
978 rename to sf_fill_buffer and install it for fill-buffer in ptob.
979 the Scheme interface is still a procedure that gets a char.
980 (scm_make_soft_port): set up the port buffer (shortbuf).
982 * fports.c (local_fgetc, local_fgets): deleted.
983 * strports.c (stgetc): likewise.
984 * ports.c: scm_generic_fgets: likewise.

990 (stfill_buffer): new proc.
992 * ports.h: fport buffer moved into port table: to be
993 used for all port types.

1006 * posix.c (scm_getgroups): use SCM_ALLOW/DEFER_INTS.
1007 (scm_ttyname): use SCM_FPORT_FDES.
1008 (scm_tcgetpgrp, scm_tcsetpgrp): likewise.

1020 * fports.c (scm_fport_buffer_add): new procedure.
1022 * fports.h (SCM_FDES_RANDOM_P): new macro. use it in
1023 scm_fdes_to_port and scm_redirect_port.

1029 filesys.c (scm_opendir):
1030 restore defer interrupts while the port is constructed.
1031 * (scm_setvbuf): if mode is _IOFBF and size is not supplied,
1032 derive buffer size from fdes or use a default.

1036 vports.c (various places): use SCM_SSTREAM.
1037 strports.c: likewise.
1038 * gdbint.c: likewise.
1039 * ports.h (SCM_SSTREAM): new macro.
1041 * fports.c (scm_input_waiting_p): use scm_return_first, since port
1042 may be removed from the stack by the tail call to scm_fdes_waiting_p.
1044 * fports.h (SCM_CLEAR_BUFFERS): new macro.
1046 * filesys.c (scm_fsync): use SCM_FDES.

1188 * strop.c (scm_string_capitalize_x): Use the SCM object `s' in

1192 * strop.c (scm_substring_move_x): New function, which can handle
1193 arbitrary overlapping substrings.

1324 1999-03-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1326 Most of this batch of changes is about how to deal with extended
1327 types when an object system is loaded into Guile. A nice object
1328 system is capable of representing Guile's types as class objects.
1330 For example, we want a regular expression to be of class <regex>.
1331 But regular expressions are smobs which aren't under direct
1332 control of the object system, so there has to be some mechanism
1333 which informs the object system that a new class should be created
1334 which can represent the smob type. I call this a "wrapper class".
1336 * objects.c: #include "smob.h";
1337 (scm_class_keyword): Removed. (Class is automatically created by
1339 (scm_smob_class): Array of smob classes indexed by smobnum.
1340 (scm_make_extended_class): "Plugin" function pointer for creation
1341 of wrapper classes for smob and struct types.
1342 (scm_class_of): Handle compiled closures. (Currently regarded as
1344 Use scm_smob_class to handle smob types;
1345 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
1346 through scm_smob_class;
1349 * smob.c (scm_newsmob): Also create a wrapper class if
1350 scm_smob_class has been initialized.
1352 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
1353 type code and smobnum.
1355 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
1356 (scm_struct_table): Weak key table with auxilliary information for
1357 struct types. Currently used for names and wrapper classes.
1358 (scm_struct_ihashq): Hash function for structs.
1359 (scm_struct_create_handle): Get/create entry in scm_struct_table.
1360 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
1361 for accessing names of vtables. The record implementation in
1362 boot-9.scm currently uses the setter to record the name of record
1363 types. When the object system is initialized, it can use this
1364 information to create wrapper classes with suitable names.
1365 (scm_init_struct): Allocate scm_struct_table.
1366 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
1367 (struct tags are a finite resource and we might want to restrict
1368 the use of tags to vtables only. E.g., Goops only uses tags for
1370 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
1372 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
1375 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
1376 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
1377 Used for access of struct table entries.
1379 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
1380 (scm_hash_fold): New procedure. Used to process all entries in a
1381 hash table (in no particular order).
1383 Argh! For the umpteenth time I got compilation errors because of
1384 the "intuitive" name `kw'. This has to have an end:
1386 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
1387 "kw" --> "keywords" everywhere.
1388 (I doubt that this will cause big compatibility problems since the
1389 application interface is unaffected.)
1391 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
1393 1999-03-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1395 * srcprop.c (scm_set_source_property_x): Bugfix: Convert line and
1396 column inums to native form.
1398 Improvement of backtraces: Introduces a new stack narrowing
1399 specifier, #t, for the inner cut. (See further in the comments in
1400 stacks.c:narrow_stack ().)

1403 (Used to flag certain system procedures which shouldn't turn up in
1406 * eval.c (scm_sym_system_module): New symbol. (Used to flag
1407 modules which aren't "user" modules and the code of which

1411 Extract the lookup closure from an environment.
1412 (scm_system_module_env_p): New function: Return non-#f if MODULE

1418 * debug.c (scm_procedure_name): Use name property in the default
1421 * gc.c, gc.h (scm_object_address): Renamed from scm_object_addr ().
1423 * objects.h (scm_si_redefined, scm_si_hashsets): Shifted.
1425 * eval.c, procs.c, procs.h, procprop.c: Renamed getter ->
1426 procedure throughout.
1428 * print.c (scm_iprin1): Removed extraneous space when printing
1429 procedure-with-setters.
1431 Entity and operator setter slots were introduced as a complement
1432 to the <procedure-with-setter> type in order to support entities
1433 and operators with setters in a reasonable and efficient way.
1434 * procs.c (scm_procedure, scm_setter): Handle entity and operator
1437 * objects.h (SCM_OPERATOR_SETTER, SCM_ENTITY_SETTER): New macros.

1449 * objects.h (SCM_OBJ_CLASS_REDEF): New macro: Find class slots
1450 directly through the instance.
1452 * objects.c (scm_class_of): Use SCM_OBJ_CLASS_REDEF.
1454 * gc.c (scm_gc_sweep): Bugfix: Look for SCM_STRUCT_F_LIGHT flag at
1455 scm_struct_i_flags instead of scm_vtable_index_layout!
1457 * list.c (scm_list_star): New procedure.
1459 1999-02-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

1489 (scm_init_readline): Call init_bouncing_parens.

1551 1. A closure where the CODE and ENV slots are used to represent
1552 the getter and a new SETTER slot is used for the setter. The
1553 original getter is stored as a `getter' procedure property. For
1554 closure getters, the CODE and ENV slots contains a copy of the
1555 getter's CODE and ENV slots. For subr getters, the CODE contains
1558 2. A compiled closure with a call to the getter in the cclo
1559 procedure. The getter and setter are stored in slots 1 and 2.
1561 3. An entity (i.e. a struct with an associated procedure) with a
1562 call to the getter in the entity procedure and the setter stored
1563 in slot 0. The original getter is stored in slot 1.
1565 4. A new primitive procedure type supported in the evaluator. The
1566 getter and setter are stored in a GETTER and SETTER slot. A call
1567 to this procedure type results in a retrieval of the getter and a
1568 jump back to the correct eval dispatcher.
1570 Representation 4 was selected because of efficiency and
1573 Rep 1 has the advantage that there is zero penalty for closure
1574 getters, but primitive getters will get considerable overhead
1575 because the procedure-with-getter will be a closure which calls
1578 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
1579 <procedure-with-setter>, but together with rep 2 it suffers from a
1580 three level dispatch for non-GOOPS getters:
1582 cclo/struct --> dispatch proc --> getter
1584 This is because the dispatch procedure must take an extra initial
1585 argument (cclo for rep 2, struct for rep 3).
1587 Rep 4 has the single disadvantage that it uses up one tc7 type
1588 code, but the plan for uniform vectors will very likely free tc7
1589 codes, so this is probably no big problem. Also note that the
1590 GETTER and SETTER slots can live directly on the heap, using the
1591 new four-word cells.
1593 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,

1620 * eval.h: Declare scm_s_set_x, scm_sym_set_x;
1622 * eval.c: Renamed "set" --> "set_x" in various names for
1623 consistency of name correspondence between Scheme and C;
1624 Renamed scm_i_set_x --> scm_sym_set_x and made global.
1625 Renamed s_set_x --> scm_s_set_x and made global.
1627 1999-01-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1629 * random.c (scm_i_random_bignum): Made independent of endianness.

1655 * random.c: Bugfix: Retrieve and store most significant 32 bits in
1656 different order if the machine is bigendian.

1662 from first arg before equal elements in second arg in result.
1663 (scm_merge_list_step): Bugfix: Don't presume that arguments in a C
1664 function call are executed in a well defined order.
1666 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
1668 * alloca.c (alloca): Cast value returned by malloc. (Thanks to
1671 1999-01-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1673 * random.c: Removed alloca includes.
1675 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
1677 * Makefile.in: This changed, for some reason I don't really
1678 understand, when I ran automake in the top level directory. This
1679 may be contamination by Cygnus internal releases. If you re-run
1680 automake and this change gets reverted, don't worry about it.
1682 1999-01-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1684 * sort.c, sort.h: New files: Implement slib's and scsh's sort
1685 interfaces. Author: Roland Orre.

1697 * random.c, random.h: New files: Random number support.
1698 Interface same as slib's.
1700 * Makefile.am: Added random.c, random.h, random.x.
1702 * init.c: #include "random.h";

1705 1998-12-23 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1707 * Makefile.am: New files: guardians.c, guardians.x, guardians.h
1709 * guardians.c, guardians.h (scm_make_guardian,
1710 scm_guardian_gc_init, scm_guardian_zombify, scm_guard,
1711 scm_get_one_zombie, scm_init_guardian): This is an implementation
1712 of guardians as described in R. Kent Dybvig, Carl Bruggeman, and
1713 David Eby (1993) "Guardians in a Generation-Based Garbage
1714 Collector" ACM SIGPLAN Conference on Programming Language Design
1715 and Implementation, June 1993 ftp://ftp.cs.indiana.edu
1716 /pub/scheme-repository/doc/pubs/guardians.ps.gz
1717 Author: Michael N. Livshin.
1719 * gc.h (SCM_MARKEDP, SCM_NMARKEDP): New macros.
1721 * gc.c (scm_igc): Call scm_guardian_gc_init and
1722 scm_guardian_zombify.

1726 1998-12-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1728 * macros.c (scm_makacro, scm_makmacro, scm_makmmacro): Added
1731 1998-12-15 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1733 Move the procedure slots of entities to invisible slots (so that
1734 we can have operator class objects which themselves are entities).
1735 * struct.h (scm_struct_i_proc, scm_struct_i_flags,
1736 SCM_STRUCTF_ENTITY): New constants.
1738 * struct.c (scm_make_struct): Allocate "invisible" room for
1739 procedures if SCM_STRUCTF_ENTITY is set in vtable.
1741 * gc.c (scm_gc_mark): Mark entity procedures.
1743 * struct.c, struct.h (scm_alloc_struct): Renamed from alloc_struct

1748 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0,
1749 SCM_ENTITY_PROC_3): Adjusted for new location of procedure slots.
1751 Mon Dec 14 18:10:12 1998 Maciej Stachowiak <mstachow@mit.edu>
1753 * snarf.h (SCM_SYNTAX): New macro to allow convenient declaration
1754 of syntactic forms, similar to SCM_PROC.
1755 * debug.c, eval.c, evalext.c: use SCM_SYNTAX to declare all special
1756 forms, and SCM_SYMBOL or SCM_GLOBAL_SYMBOL to delcare C variables
1757 for the name symbols when needed.
1759 1998-12-14 Jim Blandy <jimb@zwingli.cygnus.com>
1761 * Makefile.in: Regenerated.
1763 1998-12-05 Jim Blandy <jimb@zwingli.cygnus.com>
1765 * pairs.h (SCM_NEWCELL): When DEBUG_FREELIST is defined, don't
1766 take the address of _into; it might be a register. Just have
1767 scm_debug_newcell return the new cell.
1768 * gc.c (scm_debug_newcell): Just return the new cell, instead of
1769 taking the address of a place to store it as an argument.
1770 * gc.h (scm_debug_newcell): Change declaration.
1771 (Thanks to Greg Harvey.)
1773 1998-12-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1775 * ramap.c (array-copy-in-order!, array-map-in-order): New names.
1776 Replaces old names serial-array-copy! and serial-array-map!.

1782 * smob.c (freeprint): New function.
1783 (freecell): Use it to print freed objects, for slightly easier
1786 1998-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1788 * backtrace.c (display_frame): Made more robust. Doesn't throw an
1789 error if no source properties can be found for a frame. (Thanks
1790 to Christian Lynbech.)
1792 1998-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1794 * objects.h: Removed slots direct_supers and direct_slots from the
1795 definitions of the rudimentary classes described by objects.h.
1797 * objects.c, objects.h (scm_entity_p): New procedure. Together
1798 with the predicates scm_procedure_p and scm_struct_p, this
1799 predicate makes it possible to differ between structs, entities
1802 * modules.c, modules.h (scm_resolve_module): New function.
1804 1998-11-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1806 * objects.h (SCM_METACLASS_STANDARD_LAYOUT,
1807 SCM_METACLASS_OPERATOR_LAYOUT): Removed slots `direct_supers' and
1810 * objects.c (scm_entity_p): New procedure.
1812 * procprop.c (scm_i_procedure_arity): Bugfix: Return correct value
1813 for asubrs, rpsubrs, lsubrs and lsubr_2s.
1815 1998-11-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1817 * procprop.h (scm_i_procedure_arity): Added declaration.
1819 * procprop.c (scm_i_procedure_arity): Made global; New code to
1820 handle operators and entities.
1821 (scm_procedure_property): No need to call scm_procedure_p since
1822 scm_i_procedure_arity now does all necessary type checking.
1823 Added #include "objects.h".
1825 * feature.c (scm_remove_hook_x): Bugfix: Changed reference to
1826 s_add_hook_x --> s_remove_hook_x.
1827 (scm_add_hook_x, scm_remove_hook_x): Hooks now takes arguments.
1828 Added #include "procprop.h"
1830 * feature.c, feature.h (scm_reset_hook_x): New procedure.
1831 (scm_make_hook): Optional argument defines number of arguments to
1833 (scm_make_named_hook): Take number of args as second arg.
1834 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
1835 boot-9.scm for a while); First arg is the hook. The rest are
1836 arguments passed on to the hook procedures.
1838 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
1840 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
1841 scm_logbit_p): Do the computation in ulongs. This is not as nice
1842 as doing it in bignums, but at least it's good enough for
1843 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
1845 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
1846 subexpressions. (Thanks to Charbel Jacquin.)
1848 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
1850 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
1851 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
1852 (scm_make_named_hook): New function.
1854 * feature.c: Added #include "eval.h".
1856 * modules.c (scm_make_module): Beautify the module.
1858 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1860 * modules.c, modules.h: New files: C interface to modules. (This
1861 is necessary in order to interface the object system to Guile
1862 properly. The guts of these modules will be replaced by the new
1863 module system in the future.)
1865 * init.c: Added #include "modules.h"
1866 (scm_boot_guile_1): Call scm_init_modules.
1867 (invoke_main_func): Call scm_post_boot_init_modules.
1869 * Makefile.am: Added modules.c, modules.x, modules.h.
1871 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
1873 * procs.c: #include "objects.h"
1874 (scm_procedure_p): Return #t also on structs which are operators.
1876 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
1877 <operator-metaclass> and <entity-class> to <standard-class>,
1878 <operator-class> and <entity> in order to conform with STKlos
1881 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
1882 which isn't an operator.
1883 (SCM_APPLY): Ditto, but jump to badproc.
1885 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
1887 * eval.c (SCM_CEVAL): Allow structs implanted in code.
1888 Previously, structs implanted in code were interpreted as forms
1889 the operator of which was a gloc. We solve this by checking for
1890 the zero in the emulated vcell in the struct vtable. Since
1891 implanted structs always will look like forms with a gloc
1892 operator, execution will only be slowed down by maximally one
1893 extra test-and-branch per application.
1895 * evalext.c (scm_definedp): Removed check for isyms; Added a
1896 second optional argument: It is now possible to supply an
1897 evaluation environment in which to look for the symbol.
1899 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1901 * readline.c (scm_init_readline): Set
1902 rl_basic_word_break_characters. (Thanks to Ian Grant.)
1904 * coop.c (coop_condition_variable_wait): Removed
1905 (coop_condition_variable_wait_mutex): Folded logic of
1906 coop_mutex_unlock into coop_condition_variable_wait_mutex to
1907 prevent condvar signal lossage. Previously, another thread could
1908 start to run after unlocking the mutex but before putting the
1909 current thread on the wait queue. If that thread then would
1910 signal the first, the signal would be lost. (Thanks to Christian
1913 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1915 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
1918 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1920 * objects.c (scm_i_make_class_object): Renamed from
1921 make_class_object; exported; error checking moved to
1922 scm_make_class_object and scm_make_subclass_object.
1923 (scm_make_class_object, scm_make_subclass_object): Use
1924 scm_i_make_class_object.
1925 (scm_make_subclass_object): Let the subclass have same metaclass
1928 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1930 * debug.c (scm_debug_options): Bugfix: Set the value of
1931 scm_stack_checking_enabled_p after setting debug options;
1932 #include "stackchk.h". (Thanks to Richard Polton.)
1934 1998-11-13 Radey Shouman <rshouman@metro2000.com>
1936 * unif.c (scm_array_contents): removed unnecessary test for 0
1939 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1941 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
1942 Replaced by macro `collect' in boot-9.scm.
1944 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1946 * eval.c (scm_copy_tree): Copy source properties if existent.
1948 * debug.c (scm_start_stack): Copy source when evaluating. (If we
1949 don't, we may end up passing memoized source to a transformer.)
1951 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1953 * stack.c (get_applybody): Help function which lookups the first
1954 body form of the apply closure.
1955 (read_frames): Prevent the source of the first form of the apply
1956 closure from being recorded. This would only be confusing.
1958 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
1959 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
1961 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
1963 * stacks.c (read_frame): Bugfix: Removed lingering `else'
1965 (read_frames): Use SCM_MACROEXPP.
1967 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1969 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
1970 don't contain interesting information since all arguments are
1971 present in the frame which applies the compiled closure anyway.);
1972 Skip the transformer application frames.
1974 * print.c (scm_iprin1): Print gsubrs as primitives.
1976 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1978 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
1980 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
1981 that we can identify these in a backtrace. (This change doesn't
1982 introduce any significant speed penalty.)
1984 * eval.c: Added note about `serial-map' using scm_map.
1986 * read.c, read.h (scm_read_options, scm_read_opts): Removed
1987 readline options. They should reside in their own options array.
1989 * readline.c, readline.h (scm_readline_options,
1990 scm_readline_opts): Moved readline options here.
1992 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1994 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
1995 SCM_ROCHARS instead of SCM_CHARS.
1997 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
1998 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
2000 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2002 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
2003 This is quite important since the latter clears the
2004 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
2005 every single character read...
2007 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2009 * print.c (scm_iprin1): Removed suspect looking (and indeed
2010 malevolent) semicolon after test for user supplied closure print
2011 procedure. (Thanks to Telford Tendys.)
2013 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
2014 (scm_memq, scm_memv, scm_member): Do argument checking *before*
2015 starting to search the list. Removed call to sloppy_mem_check.
2017 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
2018 procedures: Same as scm_delq_x et al, but delete maximally one
2021 * options.c (scm_options, scm_init_options): GC-protect option
2022 values of type SCM. (Thanks to Telford Tendys.)
2024 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2026 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
2027 make sure that there always is a "real" scm_lookupcar.
2029 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2031 * read.c, read.h (scm_read_opts): New read options
2032 "history-length" and "history-file".
2033 (scm_read_options): Stifle history to history length.
2035 * readline.c (scm_read_history, scm_write_history): New procedures.
2037 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2039 * eval.h (scm_macro_eval_x): Removed declaration.
2041 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
2042 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
2043 Renamed and made global.
2045 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
2046 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
2048 * evalext.c, evalext.h: New files. Contain non-R5RS things
2049 having to do with evaluation.
2051 * evalext.c (scm_serial_map): New procedure: Version of `map'
2052 which guarantees that the procedure is applied to the lists in
2054 (scm_m_sequence_to_list): New syntax: Version of `begin' which
2055 returns a list of the results of the body forms instead of the
2056 result of the last body form.
2057 (scm_definedp, scm_m_undefine): Moved from eval.c
2059 * evalext.h (scm_m_sequence_to_list): Added declaration.
2061 * macros.c, macros.h: New files.
2062 (scm_procedure_to_syntax, scm_procedure_to_macro,
2063 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
2064 scm_macro_name, scm_macro_transformer): Moved from eval.c
2065 (scm_make_synt): Moved from eval.c
2067 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
2069 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
2072 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
2074 * debug.c, print.c: Added #include "macros.h".
2076 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2078 This change adds the ability to use `unread-char' multiple times
2079 without interspersed reads and adds the new procedure
2080 `unread-string'. The change is optimized for the common case of
2081 unreading a single character. This is also the reason behind the
2082 choice to store characters in the port itself: in most cases no
2083 extra malloc is required.
2085 The amount of code in some macros in ports.h has been increased to
2086 the extent that they would fit better as C functions, but, since
2087 this code belongs to the port representation, such functions
2088 should be placed in ports.c which would cause calls back and forth
2089 between ports.c and genio.c. That is not good for performance.
2090 Also, keeping them as macros allows the compiler to do some
2091 optimizations which are needed to make the current interface
2092 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
2094 One benchmark (Guile startup time) indicates an increase of
2095 loading speed of 1%. Another (reading (using `read') boot-9.scm
2096 10 times) shows no change in performance.
2098 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
2099 made to find a beautiful solution.)
2101 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
2102 (SCM_TRY_CLRDY): New macro: Only clear the first unread
2103 character. (SCM_CLRDY clears all.)
2104 (SCM_N_READY_CHARS): New macro: Returns number of unread
2105 characters in a port. Returns wrong answer if SCM_CRDYP is false.
2106 (struct scm_port_table): New fields: `entry' contains port table
2107 index, `cp' points to last unread char, `cbuf' is the buffer for
2108 unread chars, `cbufend' points after end of the character buffer.
2110 * ports.h, ports.c (scm_unread_string): New procedure.
2111 (scm_grow_port_cbuf): New function.
2113 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
2115 (scm_generic_fgets), fports.c (local_fgets): Use a loop
2116 to read unread characters. Use SCM_TRY_CLRDY instead of
2119 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
2121 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
2123 * genio.c, genio.h (scm_ungets): New function.
2125 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
2128 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2130 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
2131 declarations. (Thanks to Russ McManus.)
2133 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2135 * numbers.c (num2long): As a software archeologist, I'm proud of
2136 this finding! :) Preliminary dating suggests an almost 4 year old
2137 remnant from the SCM ancestor. The sample has been removed from
2138 the finding site and is now safely stored in the repository.
2140 * numbers.h: Removed prototype for num2long.
2142 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
2144 * gh_data.c (gh_scm2doubles): Make it possible to pass result
2145 array as second arg.
2146 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
2147 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
2148 * gh.h: Updated and added prototypes.
2150 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
2152 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
2154 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
2156 * guile-snarf.in: Never generate an empty file. (Thanks to
2159 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
2160 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
2161 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
2162 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
2163 gh_new_procedure5_0): Specify argument types, to appease C++
2164 compilers. (Thanks to Brad Bowman.)
2166 Bug reports from Russ McManus:
2167 * guile-snarf.in: If the CPP environment variable is set, use that
2168 as the C preprocessor, instead of the preprocessor autoconf
2170 * snarf.h (SCM_PROC): Cast the function pointer passed to
2171 scm_make_gsubr, to satisfy C++.
2173 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
2174 Use the handler passed, instead of ignoring it and using
2175 gh_standard_handler. (Thanks to Etienne Bernard.)
2177 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
2179 * ports.h: Put text after #endif in comment. (Thanks to Nicolas
2182 1998-10-19 Jim Blandy <jimb@zwingli.cygnus.com>

2199 vectors.c, vectors.h, version.h, vports.c, weaks.c: Update
2202 * script.c (scm_compile_shell_switches): Define
2203 use-emacs-interface in the root module, so the repl code can see
2204 it. See today's change to top-repl in ice-9/boot-9.scm.
2206 * filesys.c (set_element, get_element): Make sure that `element'
2207 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
2208 Boekemeier and Jorgen "forcer" Schaefer.)
2210 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
2212 * chars.c (scm_charnames): In ASCII character name table, make
2213 newlines print as #\newline by default, not #\nl.
2215 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
2216 alphabetical order. Oh thrills. But it helps me know how far
2217 along in the compilation I am.
2218 * Makefile.in: Regenerated.
2220 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2222 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
2223 #bytes(...) to #y(...), and syntax for short vectors from
2224 #short(...) to #h(...). This may seem nutty, but, like the other
2225 uniform vectors, byte vectors and short vectors want to have the
2226 same print and read syntax (and, more basic, want to have read
2227 syntax!). Changing the read syntax to use multiple characters
2228 after the hash sign breaks with the conventions used in R5RS and
2229 the conventions used for the other uniform vectors. It also
2230 introduces complexity in the current reader, both on the C and
2231 Scheme levels. (The Right solution is probably to change the
2232 syntax and prototypes for uniform vectors entirely.)
2234 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
2236 Don't use local_fgets on sockets; ftell doesn't work on sockets.
2237 (Thanks to Jorgen "forcer" Schaefer.)
2238 * ports.h (SCM_NOFTELL): New flag.
2239 * fports.c (local_fgets): If it's set, use the generic fgets.
2240 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
2242 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2244 * script.c (scm_compile_shell_switches): Add handling of -q switch
2245 (inhibit loading of user init file).
2246 (scm_shell_usage): Add usage text for -q switch.
2247 (scm_compile_shell_switches): Always load user init file first if
2248 it is loaded at all.
2250 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
2252 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
2253 and is now broken under NetBSD. I can't fathom what it's trying
2254 to do, so I've replaced it with something that I do understand,
2255 which seems to work, and which isn't broken on NetBSD. "Progress?
2256 You Decide." (Thanks to Perry Metzger.)
2258 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
2259 signed/unsigned comparison.
2261 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
2263 Warning fixes from Greg Harvey:
2264 * unif.c (scm_array_set_x): initializer for pos
2265 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
2266 * struct.c (scm_struct_ref, scm_struct_set_x): Added
2267 initializers for field_type, since EGCS so desparately wants to
2269 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
2270 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
2271 when GUILE_DEBUG is defined.
2272 * dynwind.h (scm_wind_chain): Same.
2273 * ports.h (scm_pt_size, scm_pt_member): Same.
2274 * print.h (scm_current_pstate): Same.
2275 * procs.h (scm_make_cclo): Same.
2277 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
2279 Handle short and long long uniform arrays properly. (Thanks to
2281 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
2282 raeql_1): Add cases for scm_tc7_svect (short vectors) and
2283 scm_tc7_llvect (long long vectors).
2285 Change the way libguile and boot-9.scm are timestamped, to try to
2286 get rid of these spurious mismatch warnings. Now both
2287 libguile/versiondat.h and ice-9/version.scm are generated directly
2288 by the configuration process, rather than having version.scm
2289 generated directly, and libguile/versiondat.h generated by the
2290 Makefile, which is generated by configure. It seems that
2291 sometimes the Makefile would change, but versiondat.h depends on
2292 Makefile.in, not Makefile, so it wouldn't get rebuilt.
2293 * Makefile.am (versiondat.h): Target removed; this is generated
2294 directly by the configure script now.
2295 (BUILT_SOURCES): Remove versiondat.h.
2296 * versiondat.h.in: New file, transformed by the configure script
2298 * Makefile.in: Regenerated.
2300 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
2301 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
2302 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
2303 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
2304 if we want to use them in a header file some day, we can. (Thanks
2305 to Michael Livshin.)
2307 * stime.c (scm_get_internal_real_time): Do the arithmetic using
2308 SCM numbers, so we won't have rollover problems; the range of a
2309 signed long in milliseconds is about 25 days. (Thanks to Karl
2312 Don't redefine sleep and usleep; fix this problem now.
2313 * coop.c (sleep, usleep): Remove declarations; we don't use or
2314 redefine these any more.
2315 (scm_thread_usleep, scm_thread_sleep): New functions which do the
2316 job of usleep and sleep in a thread-friendly way. We can use
2317 these in the rest of Guile. Define versions for systems both with
2318 and without iselect.
2319 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
2320 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
2321 we're just using it, not redefining it, we can use a K&R style
2323 (sleep): Declare this, too, if the system hasn't.
2324 (scm_sleep, scm_usleep): Use scm_thread_sleep and
2325 scm_uthread_sleep if they're available; otherwise, just call the
2327 * scmconfig.h.in: Regenerated.
2329 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
2331 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
2333 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
2335 * threads.c: Doc fix.
2337 The argument type of usleep varies from system to system,
2338 as does the return type. We really shouldn't be redefining usleep
2339 at all, but I don't have time to clean that up before the 1.3.
2340 release. It's on the schedule for afterwards. (Thanks to Julian
2342 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
2344 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
2345 * scmconfig.h: Regenerated.
2347 * simpos.c (scm_software_type): Procedure deleted. This isn't the
2348 right way to handle system variation. Autoconf's approach is the
2350 * simpos.h (scm_software_type): Declaration deleted.
2352 * script.c (scm_find_executable): Don't test if unix is #defined
2353 here; first, NetBSD doesn't #define it, and second, it's the wrong
2354 way to go about these things. (Thanks to Perry Metzger.)
2355 (dld_find_executable): Delete this MSDOS support code. This isn't
2356 the way we want to support this; it needs to be rethunk at a
2359 * genio.c (scm_do_read_line): Don't just politely check that the
2360 line was either non-empty or EOF. Abort if it's empty and not
2363 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
2365 * scmconfig.h.in: Regenerated.
2367 * libguile.h: Don't omit the dynamic linking functions. (Thanks
2370 * genio.c (scm_do_read_line): Count lines correctly when the file
2371 doesn't end in a newline.
2373 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
2375 * genio.c (scm_do_read_line): Maintain the line count correctly.
2376 (Thanks to Harvey J. Stein and Greg Harvey.)
2378 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
2381 * numbers.c (big2str): Protect t from garbage collection until
2382 we're done. (Thanks to Gary Houston.)
2384 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
2386 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
2388 * Makefile.in: Regenerated.
2390 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
2391 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
2394 Do magic to mix reads and writes on stdio FILE-based ports.
2395 (Thanks to Christian Lynbech.)
2396 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
2398 (pre_read, pre_write): New functions.
2399 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
2400 local_fputs): Call them.
2401 (local_fflush): Mark the port as ready for reading and writing.
2402 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
2403 flags on new port objects. This might not be accurate --- who
2404 knows what state the FILE * is in when we get it --- but it won't
2405 do extraneous calls to fflush or fseek, so it's no worse than the
2406 behavior before this change.
2407 * ports.h: Add comment.
2409 Centralize the creation of port objects based on stdio FILE * in
2410 fports.c; don't just throw them together anywhere.
2411 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
2412 what the rest of Guile wants. Don't set the revealed count;
2413 that's only appropriate for stdin, stdout, stderr.
2414 (scm_standard_stream_to_port): This function does set the revealed
2416 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
2417 not scm_stdio_to_port.
2418 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
2419 * fports.c (scm_open_file): Same.
2420 * posix.c (scm_pipe): Same.
2421 * socket.c (scm_sock_fd_to_port): Same.
2422 * ioext.c (scm_fdopen): Same.
2423 (scm_freopen): Moved from here to...
2424 * fports.c (scm_freopen): ... here. This is really something that
2425 munges the internals of an fport, so it should go here.
2426 * fports.h (scm_stdio_to_port): Adjust prototype.
2427 (scm_standard_stream_to_port, scm_freopen): New protoypes.
2428 * ioext.h (scm_freopen): Prototype removed.
2430 * filesys.c (set_element, get_element): This can work on both pipe
2431 and file ports, so use SCM_FPORTP to typecheck, instead of testing
2434 * scmconfig.h.in: Regenerated.
2436 Change the definition of the functions in scm_ptobfuns so that
2437 they get passed the port object, not the port's stream.
2438 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
2439 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
2440 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
2441 Pass the port itself to the scm_ptobs function.
2442 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
2443 scm_generic_fgets): Same.
2444 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
2445 getc_void_port, fgets_void_port, close_void_port): Just change the
2446 argument names; these functions don't really do anything.
2447 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
2448 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
2449 port as an argument, and use SCM_STREAM to get the stdio FILE *.
2450 Also, use prototyped definitions, and get rid of the extra
2452 (scm_fptob, scm_pipob): We don't need casts here any more.
2453 * strports.c (prinstpt): Use prototype declarations.
2454 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
2455 and use SCM_STREAM to get the string info. Also, use prototyped
2456 definitions, and get rid of the extra declarations.
2457 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
2460 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
2461 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
2463 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
2464 scm_fgets, for consistency.
2465 (scm_fptop, scm_pipob): References updated.
2467 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
2469 Include the source location in error messages for scripts.
2470 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
2471 stack is still there when we catch the error.
2472 * throw.c (handler_message): If we are handling an error with a
2473 message, then put together the proper arguments and call
2474 scm_display_error, instead of scm_display_error_message. That
2475 displays source location, if it can find it.
2477 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
2479 * gc.c (scm_unprotect_object): Change this so that calls to
2480 scm_protect_object and scm_unprotect_object nest properly.
2481 (scm_protect_object): Doc fixes.
2483 * strings.c (scm_string_set_x): Require the argument to be a
2484 writable string, not a substring or a symbol.
2485 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
2486 (Thanks to John Redford and Charbel Jacquin.)
2488 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
2490 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
2492 * eval.c (safe_setjmp): Remove this misunderstanding.
2493 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
2496 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
2498 * libguile.h: Mark these as C declarations, for compilation by C++
2501 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
2502 __cplusplus clause. I seriously doubt this ever worked the way
2503 the author seems to have intended.
2505 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
2507 Utterly needless cleanups to hopelessly messy code.
2508 * ports.c: Doc fixes.
2509 (scm_fflush): Moved to ...
2510 * genio.c (scm_fflush): ... here, amongst all the other port
2511 method invocation functions.
2512 * genio.h, ports.h: The prototype moves too.
2514 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
2516 * backtrace.c (display_error_body): The current frame does not
2517 always have a parent frame; consider a function called directly
2518 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
2521 * alloca.c (alloca): Undo yesterday's changes, and simply call
2522 malloc directly for storage, and abort if we don't get what we
2523 want. The situation is much simpler --- just call malloc. Emacs
2524 has bizarre/evil requirements (signal handlers might malloc unless
2525 you set this global flag, so you have to set the flag around all
2526 calls to malloc) which we are certainly not going to conform to,
2527 so we can do the simple and obvious thing.
2529 * coop.c (coop_condition_variable_wait): Make this function
2530 static. It's only useful internally --- you should never just
2531 wait on a condition variable.
2532 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
2534 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2536 * unif.c (scm_array_set_x): Accept any kind of number as an
2537 element for a uniform vector of doubles. This is more consistent
2538 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
2540 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
2541 works; I can't conveniently test it myself. (Thanks to Dvid
2542 Tillman for the bug report.)
2544 * init.c: Doc fixes.
2546 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
2547 from here, not from scm_compile_shell_switches (which is a pretty
2548 dumb place to do it).
2549 (scm_load_startup_files): New function.
2550 (scm_ice_9_already_loaded): Variable moved to here from script.c.
2551 * script.c (scm_compile_shell_switches): Don't load the startup
2553 (scm_ice_9_already_loaded): Variable moved.
2554 * init.c (scm_load_startup_files): Prototype for new function.
2555 * gh_init.c (gh_enter): Doc fix.
2557 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2559 Some anti-warning changes from Greg Harvey.
2560 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
2561 warnings when it doesn't understand our NORETURN declarations in
2563 * posix.c (scm_mknod): Similar.
2565 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2567 * posix.c (scm_getpwuid): If we can't find an entry, return our
2568 own message, instead of using scm_syserror --- the getpwMUMBLE
2569 functions don't set `errno' to anything interesting.
2571 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2573 Get rid of warnings from the cooperative threading system.
2574 * threads.h (scm_single_thread_p, scm_yield,
2575 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
2576 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
2577 scm_wait_condition_variable, scm_signal_condition_variable): Add
2578 prototypes for these Scheme-visible functions.
2579 * coop-defs.h (coop_next_runnable_thread,
2580 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
2581 Prototypes for these here, even though they're from iselect.c.
2582 (coop_condition_variable_wait, coop_join): Add prototypes.
2583 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
2584 scm_threads_free_condvar): Make these smob functions static.
2585 * coop-threads.h (coop_init): Give this a real prototype.
2586 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
2587 (coop_next_runnable_thread): No need to provide prototype; it's in
2590 * scmconfig.h.in: .detarenegeR
2592 * iselect.c, threads.c: Doc fixes.
2594 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2596 * Makefile.in: Regenerated with a patched automake, to get
2597 dependency generation right when using EGCS.
2599 * inet_aton.c (inet_aton): Add prototype, to remove compiler
2600 warning. (Thanks to Robert Pluim.)
2602 * inet_aton.c (inet_aton): Reassure the compiler that the
2603 arguments to the <ctype.h> macros are all unsigned characters, not
2606 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2608 Getting rid of more warnings...
2609 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
2610 today's change to ../configure.in.
2611 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
2612 * scmconfig.h.in: Regenertaded.de.,.__
2613 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
2614 (scm_localtime, scm_mktime): Use a const char * to manipulate the
2617 * readline.c: Doc fix.
2618 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
2619 * readline.h (scm_filename_completion_function): Add prototype.
2620 (scm_init_readline): Make this into a prototype.
2622 * readline.c (scm_filename_completion_function): Use SCM_PROC to
2623 declare this, instead of calling scm_make_subr manually.
2625 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
2627 * readline.h (scm_init_readline): Add prototype for this.
2628 (scm_init_readline): Make this a real prototype.
2630 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
2632 Warning fixes from Maciej Stachowiak:
2633 * backtrace.h (scm_display_application, scm_backtrace): Add
2635 * debug.c (scm_m_start_stack): Make this function static.
2636 * fluids.h (scm_fluid_p): Add prototype.
2637 * procprop.c (scm_i_procedure_arity): Make this function static.
2638 * regex-posix.c (scm_regexp_error_msg): Make this function static.
2639 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
2640 * root.h (scm_dynamic_root): Add external prototype.
2641 * scmsigs.h (scm_usleep): Add external prototype.
2642 * script.h (scm_init_script): Use prototype, not K&R decl.
2643 * stacks.h (scm_stack_id): Add external prototype.
2644 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
2646 1998-09-30 Mark Galassi <rosalia@cygnus.com>
2648 * gh.h: took out the definitions of vset and vref, since they are
2649 replaced by the proper vector routines that correspond to the R4RS
2652 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
2654 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
2655 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
2656 third argument, a C expression that should result in a SCM value,
2657 which is used to initialize the variable. Reimplemented
2658 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
2661 * version.h (scm_libguile_config_stamp): Add prototype.
2662 (From Maciej Stachowiak.)
2664 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
2666 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
2667 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
2669 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
2671 * print.c (scm_iprin1): Rather than having one i, and using it in
2672 several places, declare a fresh i local to each block where it is
2673 used, and give it a signedness appropriate to its use in each case.
2674 (scm_iprlist): Same.
2676 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
2677 comparison warnings.
2679 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
2680 signed/unsigned clashes.
2682 * posix.h (scm_tmpnam): Added prototype.
2684 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
2685 scm_make_subclass_object): Add external prototypes.
2687 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
2688 comparison is okay here.
2690 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
2692 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
2693 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
2695 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
2698 * load.c (swap_port): Make this function static.
2700 * load.c (scm_search_path): Make max_path_len and max_ext_len
2701 unsigned, since they're compared against string sizes.
2703 * load.c (init_build_info): Make i unsigned.
2705 * ioext.h (scm_read_line): Add prototype.
2707 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
2708 scm_hash_fn_remove_x): Make hash bucket index local variable k
2709 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
2710 accurately as possible.
2712 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
2713 comparisons, and range checking to make sure those casts are
2716 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
2717 signed/unsigned comparisons.
2719 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
2720 avoid signed/unsigned comparisons.
2721 * smob.h (scm_numsmob): Change extern declaration to match.
2723 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
2724 avoid signed/unsigned comparisons.
2725 * ports.h (scm_numptob): Change extern declaration to match.
2726 (scm_current_load_port, scm_set_port_line_x,
2727 scm_set_port_column_x): New prototypes.
2729 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
2730 test code, and it causes warnings.
2732 * gh.h (gh_int2scmb, gh_uniform_vector_length,
2733 gh_uniform_vector_ref): Added prototypes.
2735 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
2736 debugging support unconditionally. That's backtrace.c, stack.c,
2737 debug.c, and srcprop.c.
2738 (EXTRA_libguile_la_SOURCES): Omit those from here.
2739 * Makefile.in: Regenerated.
2741 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2743 * options.c (scm_options): Bugfix: Allow empty list of options!
2745 * debug.c, debug.h (scm_single_step): Removed.
2746 (scm_with_traps): New procedure. This procedure could easily be
2747 written in Scheme but needs to be highly optimized.
2749 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
2751 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
2752 Check SCM_TRAPS_P before trapping.
2754 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
2756 Changes to avoid signed/unsigned comparison warnings.
2757 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
2758 (scm_gc_sweep): Make n and j local to the blocks they're used in,
2759 so they can have appropriate types for each application. Make i
2760 signed. Use initializers in some spots. I'll probably pay for
2762 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
2763 (scm_must_realloc): Make nm unsigned.
2764 (init_heap_seg): Make new_seg_index and n_new_objects signed.
2765 (scm_init_storage): Use prototype-style definition, and make the
2767 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
2768 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
2770 * filesys.c (scm_readlink): Make local vars rv and size ints, to
2771 avoid signed/unsigned comparison warnings, and because the return
2772 value of readlink may be -1. Don't bother casting the third
2773 argument to readlink.
2775 * filesys.c (scm_dirname, scm_basename): Move these to their own
2776 page, at the end of the file.
2777 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
2779 * eval.h (scm_eval_options_interface): Add external prototype for this.
2780 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
2782 * eval.c (scm_lookupcar1): Make this static.
2784 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
2785 Make these prototype declarations, not K&R-style.
2787 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
2788 unsigned comparison warning.
2790 * appinit.c: File removed. It had a single function in it, empty,
2791 whose reason for existence is explained in no documentation or
2792 comment. I think it's there as a default for some Tcl-style
2793 initialization, but Tcl abandoned that approach a while ago.
2794 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
2795 (BUILT_SOURCES): Remove appinit.x.
2796 * Makefile.in: Regenerated.
2798 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
2800 * Makefile.in: Regenerated using the last public version of
2801 automake, not the hacked Cygnus version.
2803 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
2805 Remove Totoro kludge.
2806 * Makefile.in, scmconfig.h.in: Regenerated.
2807 * init.c, readline.c: Don't check if TOTORO is #defined.
2809 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
2811 * Makefile.am: Adjust for new thread configuration system.
2812 (INCLUDES): Include the value of THREAD_CPPFLAGS.
2813 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
2815 (THREAD_LIBS): Definition deleted; automake will generate such
2816 things automatically.
2817 * Makefile.in: Regenerated.
2819 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
2821 Simplify smob and port marking; set the mark bit in the generic
2822 marking code, and make marker routines only responsible for
2823 turning up outgoing pointers.
2824 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
2825 before calling the marking function. Don't call the marking
2826 function if it's zero.
2827 * markers.c (scm_mark0): Just return #f. This function isn't
2828 necessary at all now, but it's harmless to call it. We'll leave
2829 it in so other folks' code doesn't croak at link time.
2830 (scm_markcdr): Don't call SCM_SETGC8MARK.
2831 * async.c (mark_async): Don't call SCM_SETGC8MARK.
2832 * dynl.c (mark_dynl_obj): Same.
2833 * root.c (mark_root): Same.
2834 * srcprop.c (marksrcprops): Same.
2835 * unif.c (markra): Same.
2836 * variable.c (scm_markvar): Same.
2837 * ports.c (scm_markstream): Same.
2838 (void_port_ptob): Specify zero for our marking function.
2839 * debug.c (debugobjsmob): Same.
2840 * dynwind.c (guardsmob): Same.
2841 * filesys.c (dir_smob): Same.
2842 * fluids.c (fluid_smob): Same.
2843 * fports.c (scm_fptob, scm_pipob): Same.
2844 * mallocs.c (mallocsmob): Same.
2845 * regex-posix.c (regex_t_smob): Same.
2846 * smob.c (freecell, flob, bigob): Same.
2847 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
2848 * throw.c (jbsmob, lazy_catch_funs): Same.
2850 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2852 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
2853 scm_copy_tree on code in order not to let memoized code to leak
2854 out. Thus, scm_copy_tree needs to copy vectors as well since
2855 quasiquote can introduce evaluated code also inside vector
2858 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2860 * eval.c (scm_copy_tree): Removed ability to copy vectors.
2862 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
2863 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
2866 * unif.c: Say that ivect and uvect are of type signed and unsigned
2867 long instead of int in commentary so that it correctly describes
2870 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2872 * stime.c: Removed declaration of strptime. (It should be
2873 declared by the system headers. If it turns out that some systems
2874 don't, we'll handle that then.) (Thanks to Greg Troxel.)
2876 * stime.h: Renamed TIMEH --> STIMEH
2878 * backtrace.c (scm_display_error, scm_display_backtrace): In order
2879 to increase portability, don't use structure assignment.
2880 (Thanks to Nicolas Neuss.)
2882 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
2884 (finalize_fd_sets): Added empty statement after last case label.
2885 (Thanks to Nicolas Neuss.)
2887 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
2890 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
2892 * init.c, readline.c: OK, I won't have these readline.x bug
2893 reports anymore. We've had them since April. The current reason
2894 is a completely unintelligible failure of totoro.red-bean.com to
2895 do the test for rl_getc_function in libreadline correctly. This
2896 kludge overrides the test if we're on totoro so that the snapshot
2897 generation process can work.
2899 * readline.c: Define a strdup replacement if not existent on system.
2901 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2903 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
2904 This change makes scm_make_vector R5RS compatible. We cannot keep
2905 the third argument since people want to be able to deduce the form
2906 of the C function call only by looking at R5RS. (At the same time
2907 we have removed some unnecessary complexity!)
2909 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
2910 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
2911 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
2912 argument in call to scm_make_vector.
2914 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2916 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
2917 This macro is useful in applications.
2919 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2921 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
2922 (scm_parse_path, scm_search_path): New Scheme level procedures.
2924 * load.h (scm_internal_parse_path, scm_parse_path,
2925 scm_search_path): Declared.
2927 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2929 * filesys.c (dirname, basename): New procedures.
2931 * init.c (scm_boot_guile_1): Removed condition around
2934 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
2935 new data type (guards) for representation of C level guards and
2936 data on the wind chain.
2937 (scm_internal_dynamic_wind): New function.
2939 * dynwind.h: Declare scm_internal_dynamic_wind.
2941 * root.h (scm_root_state): Added scm_cur_loadp.
2943 * root.c (mark_root): Added comment about cur_loadp.
2945 * load.c: #include "dynwind.h";
2946 (scm_primitive_load): Use scm_inner_dynamic_wind to update
2949 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
2951 * ports.c (current-load-port): New procedure.
2953 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2955 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
2956 not a tty, return #f.
2958 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
2959 to Julian Satchell and Roland Kaufmann.)
2961 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
2962 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
2964 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2966 * debug.h, debug.c (scm_start_stack): New function. Implements
2967 the guts of old scm_m_start_stack.
2969 * debug.c (scm_m_start_stack): Use scm_start_stack.
2971 * init.c (scm_start_stack, scm_restart_stack): Renamed to
2972 start_stack and restart_stack. (These have static scope.)
2974 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2976 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
2977 readline functions to come in release 2.3. (Thanks to Chet
2979 (handle_errors): Use the above functions.
2981 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2983 * readline.c: Improvements for readline support: Handle errors
2984 better; Implement before-read-hook.
2986 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2988 * init.c (scm_boot_guile_1), readline.c: Test for
2989 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
2990 assure that we have version >= 2.1.)
2992 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
2994 * readline.c (scm_readline): Defer interrupts while we're calling
2997 * readline.c (scm_add_history): Bugfix: Do strdup before giving
2998 away the string to add_history.
2999 (completion_function): Do completion for readline. (Thanks to
3001 (scm_filename_completion_function): New procedure: Filename
3003 (current_input_getc): New function. Use this one instead of
3004 standard getc from readline.
3006 * throw.c, throw.h (scm_handle_by_throw): New function: This
3007 handler throws errors to next handler on the dynwind chain.
3009 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
3011 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
3014 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3016 * procprop.c (scm_i_procedure_arity): New function. Returns arity
3018 (scm_procedure_properties): Modified to return arity together with
3020 (scm_procedure_property): Added the read-only property `arity'.
3021 (scm_set_procedure_property_x): It is an error to set the `arity'
3024 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
3025 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
3027 * procprop.h (scm_sym_arity): New symbol.
3029 * objects.c (scm_set_object_procedure_x): New procedure: Use this
3030 to set the dispatch procedure of an operator or entity object.
3032 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
3033 Made procedure slots read-only.
3035 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
3036 scm_tcs_cons_gloc case in zero args switch; Fixed args
3037 construction for operators in scm_tcs_cons_gloc case in two args
3040 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3042 * fluids.c: Removed use of assert.h (in order to avoid
3045 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
3047 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
3049 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
3050 change makes the evaluator safer at the cost of evaluation speed.
3051 It handles the case when the user has added a non-immediate
3052 improper end of the application form, e.g., `(+ 0 . x)'.
3053 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
3054 minimize the extra cost as much as possible. The new code is
3055 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
3056 problem with structs planted directly in the code (e.g. by a
3057 macro). This no longer causes segmentation fault. (Thanks to
3060 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
3061 arg `proc' in order to be able to throw errors; New argument
3064 * Removed extra #include "debug.h"
3066 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
3068 * scmsigs.c: Declare usleep as returning void on some systems.
3069 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
3072 * coop.c (usleep): Return void on some systems.
3074 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3076 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
3078 * coop.c: Changed return type of usleep to int.
3080 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
3081 isn't found in the OS.
3083 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
3084 isn't enabled. (Thought that I had made this change ages ago...)
3086 * iselect.c: Declare bzero if not defined by OS.
3088 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3090 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
3091 condition. (Thanks to John Tobey.)
3093 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
3094 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
3097 * __scm.h: Start the long-term project of moving to POSIX threads.
3098 Phase 1: Classification of all critical sections.
3099 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
3100 for A sections. (See comments in __scm.h for details.)
3102 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
3103 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
3105 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3107 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
3108 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
3109 (libpath.h, versiondat.h): Replaced dependency on Makefile with
3110 dependencies on $(srcdir)/Makefile.in
3111 $(top_builddir)/config.status in order to avoid circularity.
3113 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
3114 from argc if argc was 0 initially.
3116 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
3117 in generation of libpath.h.
3119 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
3121 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
3122 libguile from 2 to 3.
3124 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
3126 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
3128 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
3130 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
3131 scm_set_port_column_x, scm_port_filename,
3132 scm_set_port_filename_x): Removed optional arguments. Added
3133 proper argument checking.
3135 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
3136 stack size in machine words.
3138 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
3139 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
3140 to Ole Myren Röhne.)
3142 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
3144 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
3145 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
3147 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
3150 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
3151 procedure apply: Copy argument lists before pushing them unto the
3152 environment so that the environment won't get mutated due to
3153 manipulation of procedure arguments. This should perhaps be
3154 regarded as a temporary solution until someone finds a more
3155 efficient one. (Thanks to Maciej Stachowiak.)
3157 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
3159 * script.c (scm_compile_shell_switches): Use "guile" as default
3160 zero arg if argc is NULL.
3162 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
3164 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
3165 is zero. (Thanks to Dirk Herrmann.)
3167 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
3169 * ports.c (scm_add_to_port_table): First line is now line 0
3170 (was 1). (Interface changed according to suggestion by Per
3173 * backtrace.c (display_header): Add 1 to line and column numbers
3174 when presenting them to the user.
3176 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
3177 from debug.c --> eval.c
3179 * eval.h, eval.c (scm_eval_options_interface): New options
3181 (SCM_EVAL_STACK): New option: Size of newly created stacks,
3182 i.e. stacks for new threads.
3184 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
3186 * eval.c (unsafe_setjmp): Removed with #if 0.
3188 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
3191 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
3192 to avoid compiler warnings.
3194 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
3196 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
3198 * throw.c (handler_message): Print message on current error port
3199 instead of default error port. (Thanks to Maciej Stachowiak.)
3201 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
3203 * ports.c (scm_add_to_port_table): allocate in units of
3204 struct scm_port_table *, not struct scm_port_table.
3205 * posix.c (scm_close_pipe): remove the port from the port table
3207 Thanks to Rob Engle for both fixes.
3209 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3211 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
3212 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
3214 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3216 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
3218 * backtrace.c (display_error_body, display_backtrace_body),
3219 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
3220 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
3221 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
3222 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
3225 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
3226 don't receive the jmpbuf arg anylonger.
3227 (scm_catch): Don't accept a #f tag.
3228 (scm_throw): Check that key is a symbol.
3229 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
3231 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
3233 * async.c (async_pending): Removed declaration.
3235 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3237 * dynwind.c (scm_wind_chain): New debug function.
3239 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
3240 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
3241 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
3242 extra layer of functions around the body and handler of a thread.
3243 This extra layer makes sure that the handler is called in the
3244 dynamic context of the surround (= empty dynwind list), but under
3245 the *dynamic root* of the body. We can not use the dynamic root
3246 of the surround since that root belongs to another thread => stack
3247 is not handled correctly. It may seem ugly to use this extra
3248 layer, but the extra cost in terms of execution time is really
3249 negligible compared to the total amount of time required to create
3250 a thread, and it would reduce maintainability to duplicate the
3251 crucial and complicated steps performed by cwdr.
3253 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
3254 (SCM_ALLOW_INTS): Added thread switching code before interrupts
3255 get re-enabled. The important effect of this is that interrupts
3256 are blocked during thread switching so that thread data structures
3257 don't risk getting messed up by an unfortunate signal.
3258 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
3259 seems to do more aggressive optimization which actually move
3260 instructions around in these macros in a fatal way. Therefore:
3261 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
3262 just superstitious...)
3263 (SCM_TICK): Maybe do a context switch and take care of asyncs.
3264 This macro should be used instead of SCM_ASYNC_TICK since the
3265 latter doesn't do context switches any more.
3267 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
3268 instead of SCM_ASYNC_TICK.
3270 * coop.c, iselect.c: Since thread switches are now performed with
3271 interrupts masked, we can't use the old mechanism of delivering
3272 signals immediately when they arrive. Signals must instead be
3273 delivered when the asyncs run *after* the end of the critical
3274 section in scm_internal_select. But this also means after context
3275 switch so that the signal will be delivered to a different thread.
3276 To avoid this, I have changed the protocol of
3277 coop_wait_for_runnable_thread and friends so that they are allowed
3278 to return the original thread. So, if a signal arrives during
3279 scm_internal_select, we won't any longer be forced do a context
3280 switch, but can remain in the same thread and deliver the signal
3283 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
3284 scm_asyncs_pending and made it global.
3286 * iselect.c: Small fixes.
3288 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
3289 coop_condition_variable_init, coop_condition_variable_wait,
3290 coop_condition_variable_signal): Changed return type from `void'
3291 to `int'. This is to adhere closer to the pthreads interface.
3292 This, in turn, is part of an attempt to provide C versions of the
3293 mutex and condition variable primitives which can be part of a
3294 frontend to COOP or pthreads.
3296 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
3297 coop_condition_variable_destroy): New functions.
3299 * coop-threads.c (scm_wait_condition_variable): Use
3300 coop_condition_variable_wait_mutex.
3302 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
3303 Definitions moved to coop-defs.h.
3305 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
3306 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
3307 scm_cond_destroy): New C interface to mutecis and cond vars.
3309 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3311 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
3313 * iselect.c: Now several threads can wait on the same file
3314 descriptor. The behaviour is compatible with OS select: All
3315 threads waiting for the fd return with the same status.
3317 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3319 * coop-threads.c, threads.h (scm_spawn_thread): New function.
3320 Can spawn a thread from application C code.
3322 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3324 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
3325 gh_doubles2scm): New functions.
3327 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
3329 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
3330 commented-out version of gh_eval_str()
3332 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
3334 * socket.c (scm_bind): free soka after use.
3336 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
3338 * stime.c (tzvar): new variable.
3339 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
3340 avoid memory leaks when allocating.
3342 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
3344 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
3347 * gc.c, tags.h: Doc fixes.
3349 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3351 * eval.c (macro-eval!): Removed. This function was a design bug.
3352 It allowed memoized code to leak out to the scheme level. Most
3353 things that you could do with `macro-eval!' can be done with
3356 1997-12-20 Tim Pierce <twp@skepsis.com>
3358 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
3359 scm_fgets now depends on ftell(3) to know how many bytes were
3362 1997-12-15 Tim Pierce <twp@skepsis.com>
3364 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
3365 dealing with strings.
3367 1997-12-13 Tim Pierce <twp@skepsis.com>
3369 Make %read-line more suitable for implementing read-line efficiently.
3370 * ioext.c (scm_read_line): Strip the terminating newline from a
3371 string, and return a cons of the string and its terminator.
3373 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
3374 of the string that is read is stored in this memory location.
3375 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
3376 * genio.c, genio.h (scm_do_read_line): Update caller.
3377 * ports.h (scm_ptobfuns): Update typedef.
3378 * fports.c (scm_fptob, scm_pipob): Update struct.
3380 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3382 * filesys.c (set_element): Return file descriptor.
3383 (fill_select_type): Return the highest file descriptor.
3384 (scm_select): Tell select about the highest file descriptor. On
3385 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
3386 Therefore the extra overhead for calculating the maximum fd seems
3387 to be more than compensated. Is this correct? In any case,
3388 scm_internal_select will be much faster with this info.
3389 (scm_select, fill_select_type, set_element): Don't accept any kind
3390 of object in the file descriptor list or vector.
3392 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3394 * iselect.c (finalize_fd_sets): Bugfix.
3396 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3398 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
3399 when using scm_internal_select (since we might switch to another
3402 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3404 * simpos.c (scm_system): always define: use sysmissing if not
3405 available. Check for HAVE_SYSTEM instead of _Windows (does
3406 Windows lack system or does it have an unusable one?).
3407 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
3408 Let the argument be optional: if not supplied, call system(NULL).
3410 * ports.c (scm_close_port): relax the type check from OPPORTP to
3411 PORTP; closing a closed port is allowed.
3413 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
3415 * fports.c (scm_fgets): Return if the last char in a chunk is
3416 newline. When fgets returns a string whose length is `size-1', it
3417 is ambiguous whether a whole line was retrieved, so we must check
3418 explicitly whether a line terminator is present.
3420 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3422 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
3423 before taking the CDR. (Thanks to Harald Meland.)
3425 * filesys.c (scm_stat): Slightly optimized.
3427 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
3429 * ports.c (scm_close_port): Make sure the port is open before
3432 * guile-snarf.in: Pass args through to gcc in a way that preserves
3433 whitespace boundaries. (Thanks to Greg Badros.)
3435 1997-12-02 Tim Pierce <twp@skepsis.com>
3437 * stacks.c (scm_frame_procedure): Reverse the logic in the return
3438 statement. (Thanks to Doug Evans for pointing this out.)
3440 1997-12-01 Tim Pierce <twp@skepsis.com>
3442 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
3444 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
3446 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
3447 errno macro expansion of this field name. (errno is a C
3448 preprocessor macro on some systems.)
3450 1997-11-29 Tim Pierce <twp@skepsis.com>
3452 * iselect.c: Doc fix.
3454 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
3456 * init.c (scm_start_stack): Removed initialization of
3457 scm_the_last_stack_var.
3459 * backtrace.h: Declare scm_the_last_stack_var.
3461 * backtrace.c: Define scm_the_last_stack_var.
3463 * root.c (mark_root): Don't mark the_last_stack_var.
3465 * root.h (scm_root_state): Removed the_last_stack_var.
3467 * throw.c: Added #include "fluids.h"
3468 (ss_handler): `the-last-stack' is now a fluid.
3470 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
3471 --> the_last_stack_fluid.
3473 * backtrace.c: Added #include "fluids.h"
3474 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
3475 (scm_backtrace): `the-last-stack' is now a fluid.
3477 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
3478 after scm_init_fluids.
3480 1997-11-28 Tim Pierce <twp@skepsis.com>
3482 * iselect.c: #ifdef USE_THREADS around thread-related includes.
3484 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
3485 DLSYM_ADDS_USCORE to decide whether to add an underscore.
3487 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3489 * iselect.c (coop_next_runnable_thread,
3490 coop_wait_for_runnable_thread): Disable interrupts so that no
3491 async is executed before a potential error_revive.
3492 (scm_internal_select): Disable interrupts during the parts of the
3493 code which manipulate the sleep queue and the file descriptors.
3495 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3497 * Makefile.am: Added iselect.c and iselect.h.
3499 * coop.c (coop_qinit): Initialize fields used by
3500 scm_internal_select.
3501 (coop_qget, coop_qget, coop_tmp_queue): Made global.
3502 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
3503 replacement in iselect.c.
3504 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
3505 coop_join): If GUILE_ISELECT enabled, use
3506 coop_wait_for_runnable_thread instead of
3507 coop_next_runnable_thread.
3508 (usleep, sleep): New replacements for system functions if
3509 GUILE_ISELECT is enabled.
3511 * coop-threads.h: Declare coop_wait_for_runnable_thread.
3513 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
3515 * filesys.c: Added #include "iselect.h". Moved FD-macros to
3516 iselect.h. Implement Scheme level `select' using
3517 scm_internal_select. (See NEWS.)
3519 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
3521 * init.c: Call scm_init_iselect.
3523 * iselect.h, iselect.c: New files. Implements
3524 scm_internal_select. (See NEWS.)
3526 1997-11-27 Tim Pierce <twp@skepsis.com>
3528 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
3529 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
3530 and scm_must_free, since ultimately the string returned will be copied
3531 by scm_makfrom0str anyway. Also, read any characters that may have
3532 been pushed onto the port with scm_ungetc.
3533 * ports.c (scm_generic_fgets): Same as for scm_fgets.
3534 * ioext.c (scm_read_line): Free string after Guilifying it.

3545 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
3546 gh_repl (argc, argv).
3548 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
3550 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
3551 and to invoke scm_shell().
3552 (gh_launch_pad): took out the loading of boot-9.scm from here,
3553 since it is probably best to let the user control that. In fact,
3554 gh_repl() now invokes scm_shell() which does that.
3556 1997-11-23 Mark Galassi <rosalia@cygnus.com>
3558 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()

3580 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
3581 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
3583 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
3585 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when

3593 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
3595 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
3596 OPORT is an `open' port, not an output port.

3605 scm_close_all_ports_except, scm_set_current_output_port,
3606 scm_set_current_error_port): Likewise
3607 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
3608 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):

3620 Minor problems with substring-related tag changes.
3621 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
3622 exactly what we want to leave in to detect substrings.
3623 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
3624 * tags.h: Fix diagrams and comments describing the S tag bit;
3625 remove vestigial remarks about the D tag bit.

3627 * strings.c: Formatting tweaks.
3629 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
3630 variable first; then SCHEME_LOAD_PATH, with a warning message.
3631 (scm_parse_path): New function.
3632 * script.c: Doc fixes.
3634 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
3636 Readline support, from Daniel Risacher.
3637 * readline.c, readline.h: New files.
3638 * init.c: #include "readline.h".
3639 (scm_boot_guile_1): Call scm_init_readline, if we have it.
3640 * Makefile.am (libguile_la_SOURCES): Include readline.c.
3641 * Makefile.in: Regenerated.
3642 * scmconfig.h.in: Regenerated, after change to ../configure.
3644 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
3646 * gh.h: gh_vector_set -> gh_vector_set_x
3648 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
3650 * gh_data.c (gh_vector_set_x): changed name to make it consistent
3651 with the ! -> _x mapping when going from Scheme to C.
3653 1997-10-19 Mark Galassi <rosalia@cygnus.com>
3655 * gh.h (gh_reverse):
3663 (gh_assoc): added these gh_ functions implemented as macros.
3665 * gh_predicates.c (gh_null_p):
3666 (gh_string_equal_p): added these two missing predicates.
3668 * gh_list.c (gh_append):
3673 (gh_set_cdr_x): added these routines as I go through and try to
3674 complete the picture R4RS functions that should be mirrored in the
3677 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3679 * tags.h (scm_tc7_substring): Changed the comment and code to
3680 conform with the changes below. Folks! We have suddenly two new
3681 free tc7 codes!!! Jummy, jummy!

3712 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
3714 Don't include "mbstrings.h".
3715 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
3716 (SCM_SYMBOL_SLOTS): Define as 4.

3741 1997-10-12 Mark Galassi <rosalia@cygnus.com>
3743 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
3745 * gh_test_c.c (c_vector_test): some improvements on the vector
3748 * gh.h (gh_vector): this used to exist but do the wrong thing.
3749 Now it (almost) does the right thing, though it takes a list
3750 instead of the individual arguments. I need to see how it could
3752 (gh_list_to_vector): added this function as a macro. Corresponds
3753 to Scheme's (list->vector ...).
3754 (gh_vector_to_list): added this function as a macro. Corresponds
3755 to Scheme's (vector->list ...).
3757 * gh_data.c (gh_vector_ref): renamed from gh_vref to
3758 gh_vector_ref, so that it resembles the Scheme routines more.
3759 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
3760 resembles the Scheme routines more.
3761 (gh_make_vector): this used to be (stupidly) called gh_vector().
3762 This is the right name, since it does the same thing as the Scheme
3763 (make-vector ...) procedure.
3765 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
3767 * ports.h: #include "libguile/print.h"

3770 Some indentation fixes.
3772 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
3773 longer a user field; New field: class_flags.
3775 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
3777 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
3779 * gh_data.c (gh_bool2scm): new function which replaces
3780 gh_int2scmb(), which is now tagged as obsolete.
3782 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
3784 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
3785 macros should by convention not test for NIMPness.)
3786 (SCM_COERCE_OPORT): Adjust indentation.
3788 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
3789 SCM_NIMP test before SCM_PRINT_STATE_P.
3791 * struct.c, struct.h, gc.c: Renamed:
3792 scm_struct_i_layout --> scm_vtable_index_layout
3793 scm_struct_i_vcell --> scm_vtable_index_vcell
3794 scm_struct_i_vtable --> scm_vtable_index_vtable
3795 scm_struct_i_printer --> scm_vtable_index_printer
3796 scm_struct_i_vtable_offset --> scm_vtable_offset_user
3798 * struct.c (scm_print_struct): Use new printer slot; Default
3799 printing: Also output hex code of vtable so that type identity
3800 will be indicated as well.
3801 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
3802 Removed struct_printer_var; Removed struct-vtable-offset;
3803 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
3804 vtable-offset-user): New constants.
3806 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
3807 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
3808 If this slot contains a procedure, use that to print structures of
3809 the type represented by this vtable.
3811 * print.c (scm_iprin1): Don't print arguments of macro
3812 transformers. (They are always: exp env.); Bugfix: Unmemoize
3813 transformer source with correct environment.
3815 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
3817 Streamlining of call-with-dynamic-root:
3819 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
3820 there is now only one catch.
3821 (cwdr_outer_body): Removed.
3822 (cwdr_handler): New function.
3823 (scm_internal_cwdr): New function to perform the function of cwdr
3824 but take args that are more useful to C code. Also, the handler
3825 is now invoked *outside* of the new dynamic root, like the docs
3826 say. We no longer have to catch absolutely all errors, the caller
3827 is responsible for using a handler that does not throw, if he
3829 (cwdr): Reimplemented in terms of scm_internal_cwdr.
3830 * root.h (scm_internal_cwdr): New prototype.
3832 Even more but risky streamlining:
3834 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
3835 allocation of the jumpbuf of a root continuation. The changes
3836 below are controlled by it. They are now deactivated.
3837 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
3838 the JMPBUF of the scm_rootcont to NULL before returning.
3840 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
3841 when they are non-NULL.
3842 (scm_gc_mark): Likewise, mark only when non-NULL.
3844 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
3845 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
3847 * gc.c (scm_done_malloc): New function.
3848 gc.h (scm_done_malloc): New prototype.
3850 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.

3857 a certain value is acceptable as a port argument.
3858 (scm_print_state_vtable): New variable.
3859 (scm_free_print_state): Set `revealed' field to false.
3860 (scm_iprin1): Call user supplied closure printer with
3861 scm_printer_apply. Print in the traditional way when there isn't
3862 one or when it returns #f.
3863 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
3864 Accept a port/print-state pair in addition to just a port.
3865 (scm_prin1): Don't return the print_state to the pool when it has
3867 (scm_printer_apply): Set `revealed' field of print_state to true.
3868 (scm_init_print): Set scm_print_state_vtable.
3869 (print_state_fluid, print_state_fluid_num): Removed.
3871 * throw.h (scm_handle_by_proc_catching_all): New prototype
3872 throw.c (scm_handle_by_proc_catching_all): New function
3874 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
3876 * Makefile.in: Regenerated with automake 1.2c.
3878 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
3880 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
3881 was looping endlessly.
3883 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
3885 * strports.c (scm_eval_string): Don't close the port.
3887 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
3888 former returns a nice normal integer. (Thanks to Daniel
3891 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
3893 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
3894 makefile variable as a build parameter called LIBS. The
3895 build-guile program will use this, for the time being.
3896 * Makefile.in: Regenerated.
3898 Thanks to Shiro Kawai:
3899 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
3900 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
3903 * Makefile.in: Regenerated with automake 1.2a.
3905 * script.c (scm_compile_shell_switches): If we hit the -c or --
3906 arguments, don't set the car of (command-line) to scm_usage_name,
3907 the prettified name of the guile executable; give it the full
3908 path, the way shells usually handle $0.
3910 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3912 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
3913 Scheme-level name `array-map' and renamed `serial-array-map' to
3914 `serial-array-map!'.
3916 * backtrace.c: Introduced exception handlers which now enclose
3917 `display-error' and `display-backtrace' so that error reporting
3918 won't get into infinite loops if an error occurs during displaying
3919 of the error. This can very easily happen with user supplied
3920 print call-back routines.
3922 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3924 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
3925 the names `serial-array-map' and `array-map' should be removed.)
3927 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
3929 * init.c (scm_boot_guile_1): Added scm_init_objects ().
3930 Added #include "objects.h"
3932 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
3933 Add #include "feature.h".
3935 * Makefile.am (libguile_la_SOURCES): Added objects.c.
3936 (modinclude_HEADERS): Added objects.h.
3938 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
3939 This test is needed at many places in the code and should be
3940 abstracted. (Motivated by the need of this test in libguiletk.)
3942 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
3943 (scm_eval_string), load.c (scm_primitive_load,
3944 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
3945 Use SCM_EOF_OBJECT_P.
3947 * eval.c (scm_init_eval): Add feature `delay'.
3949 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3951 * scmhob.h: Removed.
3953 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3955 * list.h (SCM_LISTn): New macros. Make list creation in C code
3956 prettier. The idea comes from STk.
3958 * sequences.h, sequences.c, append.h, append.c: Removed. These
3959 files implemented non-R4RS operations which would encourage
3960 non-portable programming style and less easy-to-read code.
3962 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
3965 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
3966 sequences.h, #include append.h.
3968 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
3971 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
3973 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
3975 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
3977 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3979 * eval.c: Added #include "objects.h"
3981 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
3984 * smob.c (scm_smob_prehistory): Create two objectsmobs with
3985 adjacent smob numbers.
3987 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3989 * procprop.h: Added declaration of scm_i_inner_name.
3991 * gsubr.c: New global symbol scm_i_inner_name.
3993 * debug.c (scm_procedure_name): Try procedure property
3994 `inner-name' if `name' fails.
3996 * print.c (scm_iprin1): Use scm_macro_name.
3998 * eval.c (scm_m_define): Give names to macros as well; Only the
3999 first top-level definition gives a procedure/macro a name.
4000 Otherwise confusing names can turn up in backtraces.
4001 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
4002 `name'; Give names to macros as well.
4004 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
4005 (scm_macro_transformer): Use SCM_CLOSUREP instead of
4008 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4010 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
4012 (prinmacro): Removed. The code has been moved/merged into print.c
4013 in order to decrease code redundancy. We want macros to print in
4014 a way equivalent to procedures, and it would be silly to duplicate
4015 the required code. (We don't want to maintain two places.)
4016 (macrosmob): Print field is now a NULL pointer.
4018 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
4019 scm_macro_transformer): New prototypes.
4020 (scm_tc16_macro): Declared.
4022 * print.c (scm_iprin1): Added code for printing of macros. Macros
4023 are now printed in a way equivalent to procedures.
4025 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
4027 * procs.h (scm_closure_p): Added declaration.
4029 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4031 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
4032 Shouldn't pass "heap" as the subr name.
4034 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
4036 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
4037 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
4038 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
4039 gh_equal_p): Use SCM_NFALSEP, instead of testing against
4040 SCM_BOOL_T. Any non-false value is true.
4042 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4044 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
4045 scm_gensym): Added prototypes.
4047 * symbols.c (scm_gensym): New function. This will speed up
4048 certain types of applications (such as macro systems) which
4049 generate lots of symbols.
4051 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4053 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
4055 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
4057 * unif.c (scm_shap2ra): tighten the checking of the array dimension
4058 specifier, since (2) or (2 . 3) would cause SEGV.
4059 (scm_transpose_array): more argument checking fixes.
4061 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
4063 * Makefile.in: Regenerated.
4065 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
4067 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
4069 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4071 * error.c, error.h (scm_error_callback): Removed (see NEWS).
4073 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
4075 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
4076 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
4079 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
4080 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
4081 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
4082 scm_array_p, scm_array_rank, scm_array_dimensions,
4083 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
4084 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
4085 scm_array_prototype): Added case scm_tc7_wvect.
4087 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
4089 * errno.h: prototype for scm_strerror.
4090 * error.c (scm_strerror): new procedure.
4092 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4094 * list.c (scm_list_append_x): Allow non-pair as last argument.
4095 This is consistent with the R4RS append and is probably the
4096 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
4098 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4100 * stime.h: prototype for scm_times.
4101 * stime.c (scm_times): new procedure.

4111 (scm_truncate_file): new procedure.
4112 Add DEFER/ALLOW INTS to a few other procedures.
4113 (scm_fsync): new procedure.
4114 (scm_open_fdes): new procedure.
4115 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will

4118 third argument is now optional.
4120 * posix.c (scm_execl, scm_execlp): make the filename argument
4121 compulsory, since omitting it causes SEGV.
4122 (scm_sync): return unspecified instead of #f.
4123 (scm_execle): new procedure.
4124 (environ_list_to_c): new procedure.
4125 (scm_environ): use environ_list_to_c. disable interrupts.
4126 (scm_convert_exec_args): take pos and subr arguments and
4127 improve error checking.
4129 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4131 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
4132 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
4133 argument to SCM_ASSERT. Furthermore, the name of the function
4134 should be passed as first argument when signalling
4135 SCM_WNA. (Thanks to Thomas Morgan)
4137 * gsubr.c (scm_gsubr_apply): From Radey Shouman
4138 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
4139 dispatches on the number of actual args has a default case
4140 reporting an internal error. This is a vestige from a version
4141 that mallocated a SCM vector to hold the arguments. In the
4142 current version this check is too late: if it ever happens we will
4143 have already overstepped the bounds of the array.
4145 Also, the patch [...] adds a check for too many actual arguments."
4147 mdj: Removed check for "internal programming error".
4149 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4151 * gh_io.c (gh_write): New function.
4153 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
4154 throw.c (scm_internal_stack_catch): New sibling to the other catch
4155 functions. Code moved from gh_eval.c.
4156 throw.h: Added header.
4157 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
4158 scm_internal_stack_catch.

4162 * ioext.h: fix up prototypes.
4163 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
4164 Scheme name is now dup->fdes.
4165 (scm_dup_to_fdes): make the second argument optional and
4166 fold in the functionality of scm_primitive_dup.
4167 (scm_primitive_dup): deleted.
4169 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
4171 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
4172 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
4173 ultrix are defined. Use setvbuf instead of setbuf.
4174 (scm_setvbuf): new procedure.
4175 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
4176 (scm_setfileno): moved from ioext.c.

4188 state as nested data while they are printed.
4189 (print_state_fluid, print_state_fluid_num): New variables.
4190 (scm_init_print): Initialize them.
4191 (scm_iprin): If print_state_fluid carries a print_state, use that
4192 instead of creating a new one.
4193 (scm_printer_apply, apply_stub, struct apply_data): New
4194 definitions to help with calling printer functions written in
4196 * print.h (scm_printer_apply): New prototype.

4209 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
4210 SCM_ASSERT: arg comes before pos.
4212 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4214 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
4215 to a list of length zero correctly.
4217 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>

4233 * ioext.h: removed scm_duplicate_port prototype.
4235 * ioext.c (scm_primitive_dup2): return the new file descriptor
4236 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
4238 (scm_fdopen): bug fix: don't try to make port unbuffered until its
4239 stream has been set.
4240 (scm_duplicate_port): deleted, there's now an implementation in
4242 (scm_primitive_dup2): do nothing if newfd == oldfd.
4244 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>

4255 * ports.h: prototypes too.
4256 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
4258 * fports.h: prototype too.
4259 * fports.c (scm_evict_ports): moved from ioext.c.
4261 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>

4266 * filesys.h: scm_close prototype.
4267 * filesys.c (scm_close): new procedure, can close file descriptors
4268 and ports (scsh compatible).
4270 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an

4292 * dynl.c (free_dynl_obj): New function to free the dynamic object
4293 data. (dynl_smob): Use it.
4294 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
4295 the dynamic object data below the linking of the object to avoid
4296 memory leak when the linking code throws an error. Now the code
4297 leaks a whole dynamically linked library when must_malloc throws,
4298 but that should be much less likely.
4300 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
4302 Changes to compile under gnu-win32, from Marcus Daniels:

4340 think this is left over from the (eq? '() #f) days.
4342 * read.c (recsexpr): Give this a dummy definition if
4343 DEBUG_EXTENSIONS isn't #defined.
4345 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
4347 * coop-threads.c (scm_wait_condition_variable): Lock mutex again

4358 alloca.lo will be included in @LIBLOBJS@. Something better than
4359 this should be possible.
4360 * Makefile.in: Regenerated.
4362 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>

4372 have to do this explicitly. Also, if regexp/basic is supplied, then
4373 turn off REG_EXTENDED.
4374 (scm_init_regex_posix): New regexp/basic symbol.
4375 (REG_BASIC): #define this if it is not already present.

4398 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
4400 (scm_init_regex_posix): Define constants for the REG_mumble flags;

4418 * root.c: Establish a reliable catch-all handler for the new root.
4419 After all the Scheme handler function might signal an error too,
4420 and we don't want to lose that.

4422 (cwdr_outer_body): New function, to establish the user's handler,
4423 and pass control to cwdr_inner_body.

4434 across this. Only works on GCC. Otherwise, we hope for the best.
4435 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
4436 the feeling that real thread systems will not need this...
4438 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
4440 Try to detect when people are using one version of libguile and a

4452 primitive definitions under their Scheme names.
4454 * Makefile.am (libguile_la_LDFLAGS): Update library version to
4455 1:2. Helps avoid confusion between installed and uninstalled libs.
4457 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
4460 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
4461 backslash from definition; this should be used like: GDB_INTERFACE;
4463 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4465 * ioext.c (scm_duplicate_port): bug fix: don't try to make the

4468 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
4470 * ports.h: new prototype.
4471 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
4473 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
4475 Make things compile neatly under Sun's C compiler.
4476 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
4477 * extchrs.c (xmbtowc): Make the second arg a normal char, not
4478 unsigned, because that's what the ANSI function takes.
4479 * extchrs.h (xmbtowc): Corresponding change to prototype.
4480 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
4482 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
4483 argument plain char *.
4484 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
4486 * tag.c (scm_tag): Remove unreachable statement.
4487 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
4488 top of the word, it should be unsigned.
4490 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
4491 is defined, to avoid warnings; it's only used in the
4492 conflict-checking code. Which might go away anyway.
4493 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
4494 conditionals; put the label definition in an #if too, to stifle
4497 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
4498 ChangeLog-threads in the distribution.
4499 * Makefile.in: Regenerated.
4501 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4503 * guile-snarf.in: Changed regexp to support CPPs that insert
4504 whitespace between lexical tokens (which munges the `%%%' snarf
4507 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4509 * load.c (scm_init_load_path): Append $(datadir)/guile to
4510 %load-path, so modules do not have to be installed in Guile's
4511 current version directory.
4513 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
4515 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
4516 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
4517 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
4518 call the sysdep functions with deferred ints.
4519 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
4520 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
4521 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
4524 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
4527 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
4529 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
4531 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
4533 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
4536 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
4538 * eval.c (scm_lookupcar1): New procedure to cope with a race
4539 condition during lookup (when using threads).
4540 (scm_lookupcar): Implement in terms of scm_lookupcar1.
4541 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
4544 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
4546 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
4547 supplied. (Change from Tim Pierce.)
4549 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
4551 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
4552 23:47:01 1997" changelog: Slots are now initialized with `#f' by
4553 default and not `()'. `#f' is the canonical non-value in Scheme,
4556 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4558 * struct.c (struct_printer): New variable that holds a handle on
4559 the Scheme variable *struct-printer*. This variable can be set by
4560 Scheme code to override the printing of structures.
4561 (scm_print_struct): If struct_printer is set, call it. If it is
4562 not set, or returns #f, print the structure in the old fashion.
4563 Include "eval.h" for scm_apply.
4565 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
4567 * struct.c (scm_struct_ref, scm_struct_set_x): Use
4568 scm_struct_i_n_words to get the number of fields, not
4569 -scm_struct_n_extra_words.
4571 On the route to fancier struct printing:
4572 * struct.c (scm_print_struct): New function to print a structure.
4573 Include "genio.h" to support it. This function doesn't do
4574 anything interesting right now, but I think it should be here
4576 * struct.h: Include "print.h" and add prototype for
4578 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
4579 print structures ourself.
4581 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
4583 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
4584 before applying the handler in case it doesn't return.
4586 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
4588 * scmsigs.h, async.h: updated.
4590 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
4593 * posix.c (scm_uname): interpret only negative values as an error.
4594 Solaris normally returns a positive value.
4596 * script.c (scm_compile_shell_switches): if we are not going into
4597 an interactive repl, set scm_mask_ints to zero so that asyncs can
4600 * simpos.c (scm_system): don't ignore/unignore signals around
4603 * posix.c (scm_open_pipe): don't ignore/unignore signals around
4606 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
4607 done in boot-9.scm instead.
4609 * scmsigs.c, async.c: Major rewriting of signal handling code.
4610 (scm_sigaction): new procedure.
4611 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
4613 (scm_raise): return unspecified, throw error on failure.
4615 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
4617 * regex-posix.c (scm_init_regex_posix): Register the "regex"
4618 feature, to help boot-9.scm decide whether to import the regex
4621 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
4623 * eval.c: Include scmconfig.h at the beginning of the file so that
4624 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
4627 * regex-posix.c: #include "_scm.h" before conditionally #including
4628 <regex.h>; the former defines HAVE_REGCOMP.
4630 * regex-posix.c: #include <regex.h> conditionally, so the file is
4631 CPP'able (for dependency scanning) even on systems that don't have
4634 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
4636 Add new R4RS-compliant syntax for keywords.
4637 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
4638 regardless of the setting of the `keywords' read option.
4639 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
4640 can be re-read no matter what the setting of the `keywords' read
4643 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
4645 Add support for POSIX regular expressions.
4647 * regex-posix.c, regex-posix.h: New files. (Some code
4648 is taken liberally from rx/rgx.c in the old Guile dist.)
4650 * init.c: Include regex-posix.h.
4651 (scm_boot_guile_1): Call scm_init_regex_posix.
4653 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
4654 Add regex-posix.[ch] sources.
4655 * Makefile.in: Regenerated.
4657 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
4658 to do this automatically? It didn't for me, bleh.)
4660 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
4662 * fports.c (print_pipe_port): New function.
4663 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
4664 latter doesn't even take the right arguments.
4666 * Makefile.am: Increment shared lib revision number. I think
4667 sometimes the uninstalled Guile finds the installed shared lib;
4668 Gord says doing this might help. As things turned out, I can't
4669 say whether it does.
4670 * Makefile.in: Regenerated.
4672 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
4673 passing it as the closure argument to scm_boot_guile. (Bill
4676 * ports.c (print_void_port, putc_void_port, puts_void_port,
4677 write_void_port, flush_void_port, getc_void_port, close_void_port,
4678 noop0): Use ANSI prototypes instead of K&R declarations, so the
4679 initialization of void_port_ptob gets aggressively type-checked.
4680 Fix arguments of print_void_port and write_void_port. (Bill

4714 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
4716 * script.c (scm_find_executable): Use prototype-style definition
4717 here; apparently it's not quite right to have const in a prototype
4718 and then use a K&R declaration. I wonder if stuff like this will
4719 go away if we compile with -Wrequire-prototypes, or whatever that
4720 is... (Bernard URBAN)
4722 * scmhob.h: New text from Bernard URBAN.
4724 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
4726 * script.c: Don't #define const on hpux. Configure takes care of
4727 this. (Thanks to Larry Schwimmer.)
4729 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
4730 decide whether to #include <unistd.h>, instead of listing a bunch
4731 of systems. Don't #include stdio twice. Removed dyked-out
4732 definition of scm_find_impl_file.
4734 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
4736 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
4737 library version info to 1:0.
4738 * Makefile.in: Regenerated.
4740 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

4744 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
4745 throw.c: Update copyright years; these files have been worked on
4746 significantly in 1997, but only had copyright years for 1996.
4747 Also, change name of copyright holder on some from Mikael
4748 Djurfeldt to Free Software Foundation; he has signed papers
4749 assigning the changes to the FSF.
4751 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
4752 reason not to give the user the option.
4754 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
4755 Return #f on end-of-file when scanning table (i.e. when called
4756 with no arguments). Try to catch errors, when we can.
4757 * posix.c (scm_getgrgid, scm_getpwuid): Same.
4759 * script.h (scm_shell_usage, scm_compile_shell_switches): New
4760 external declarations. These are useful.
4762 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
4764 * posix.c: don't include <sys/select.h> or define macros for
4765 select, since they were not used in this file.
4767 * filesys.c (scm_select): make the fifth parameter microseconds,
4768 not milliseconds. let the fourth parameter be either a real value
4769 or an integer or #f. The first, second and third arguments can
4770 now be vectors: the type of the corresponding return set will be
4772 (set_element, get_element): new static procedures.
4774 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
4776 * strports.c (scm_eval_string): New function.
4777 (scm_eval_0str): Trivially re-implemented in terms of
4779 * strports.h (scm_eval_string): New extern decl.
4781 * net_db.c (h_errno): Add extern decl for this.
4783 * fports.c (local_pclose): New function.
4784 (scm_pipob): Use it in the initializer here.
4787 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
4788 Use a meaningful error message when signalling an error. For
4789 this, scm_gethost must check h_errno rather than errno.
4791 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
4793 * Makefile.in: Regenerated, using automake-1.1p.
4795 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
4797 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
4798 not SCM_UNSPECIFIED.
4800 * script.c (scm_compile_shell_switches): don't append (quit) if
4802 (scm_shell): call scm_exit_status and exit on the result of the
4805 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
4807 Ensure that shared substrings are handled properly when passed to
4808 a system call or other foreign function. Many thanks to Tim
4810 * symbols.h (SCM_COERCE_SUBSTR): new macro.
4811 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
4812 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
4813 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

4824 scm_strftime), vports.c (scm_make_soft_port): use
4825 SCM_COERCE_SUBSTR to make sure shared substrings are
4828 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
4830 * error.c (scm_error): Add newline to error message.
4832 * init.c (scm_init_standard_ports): Doc fix.
4834 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4836 * dynl-shl.c: Completely replaced with new code from Bernard
4839 * script.c (scm_ice_9_already_loaded): New variable.
4840 (scm_compile_shell_switches): Use it.
4842 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
4844 * filesys.c (scm_input_waiting_p): add missing third argument to

4848 calling gmtime in case they share a buffer.
4849 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
4852 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
4854 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
4856 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
4858 * Makefile.am (check-local): New target, which causes 'make check'
4859 to run gh_test_c and gh_test_repl, with some trivial input.
4860 * Makefile.in: Rgnrtd.
4862 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
4864 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
4867 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
4869 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
4870 sure how this was supposed to work.
4871 (scm_async_click): don't send SCM_TICK_SIGNAL.
4872 (scm_init_async): don't initialize %tick-thunk.
4874 * the following change doesn't affect the Scheme interface:
4875 gc-thunk is called at the end of garbage collection. however it's
4876 no longer implemented by pretending it's a signal.
4878 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
4879 system async corresponding to scm_gc_thunk.
4880 * async.h: declare scm_gc_async.
4881 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
4882 gc-thunk directly, instead of going through a signal handler.
4883 (scm_gc_async): new variable, points to the GC system-async.
4884 (scm_init_async): save the GC async as scm_gc_async instead
4885 of using system_signal_asyncs.
4886 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
4888 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>

4891 Don't screw up if we're interrupted.
4892 * Makefile.in: Regeneradet.
4894 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
4896 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
4898 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
4899 we're not using AM_INIT_GUILE_MODULE any more.
4900 * Makefile.in: Reneregated.
4902 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
4904 Functions for finding variable bindings, grace à Tim Pierce.

4908 Get 'make dist' to work again.
4909 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
4910 * Makefile.in: Regenerated, like a surry without a fringe on top.
4912 Changes for reduced Guile distribution: one configure script,
4914 * configure.in, configure: Removed.
4915 * acconfig.h, acinclude.m4: Moved to parent directory, where the
4916 real configure script lives.
4917 * Makefile.in, scmconfig.h.in: Regenerated.
4919 * init.c: #include "script.h", to get prototype for script.c's
4922 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
4924 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
4925 scm_must_malloc, not raw malloc.
4927 * script.c (scm_compile_shell_switches): Dyke out debugging output
4930 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4932 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
4934 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
4935 system has them. Hope this is safe. Previously
4936 sys/timeb.h was included if HAVE_FTIME was defined or if
4937 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
4938 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
4940 * ioext.c (scm_setfileno): add missing third argument to
4941 scm_misc_error call.
4943 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
4945 * eq.c (scm_equal_p): Correctly compare strings of different
4946 varieties. (Thanks to Tim Pierce.)
4948 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
4950 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
4951 #! block comment must occur on a line all by itself.
4953 Move most of the guts of shell command processing into libguile,
4954 so guile.c can be very small (and eventuallly auto-generated. (I
4955 mean, generated mechanically, not self-generated. Hmm.))
4956 * guile.c, script.c, script.h: New source files.
4957 * init.c (scm_boot_guile_1): Call scm_init_script.
4958 * libguile.h: #include "script.h".
4959 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
4960 targets, for new executable.
4961 (libguile_la_SOURCES): Mention script.c.
4962 (modinclude_HEADERS): Add script.h.
4963 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
4964 not dynamic linking is enabled. This is because we're generating
4965 executables now. Move CY_AC_WITH_THREADS call after those, so the
4966 values of cy_cv_threads_libs captures the libs chosen above.
4967 * Makefile.in, configure, aclocal.m4: Regenerated.
4969 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
4970 We don't maintain this interface any more, and it just confuses
4973 * alloca.c: #include <scmconfig.h>, not <config.h>.
4974 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
4975 it'll get included in disties.
4977 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
4979 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
4980 be distributed, because they confuse people.
4981 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
4983 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
4985 * configure.in: check for presence of gethostent (not present on
4986 OpenBSD by default).
4987 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
4988 * configure, scmconfig.h.in: Regenerated.
4990 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
4992 * backtrace.c (scm_backtrace): Split message string across
4993 newlines properly. GCC is more tolerant of this than other

5004 (modinclude_HEADERS): Add threads.h, coop-defs.h.
5005 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5006 coop-threads.c.cygnus, coop-threads.h.cygnus.
5007 * configure.in: If we're using threads, include threads.o in
5009 * _scm.h, libguile.h: threads.h lives in this directory now.
5010 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5011 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
5012 currently used, but brought along for information's sake.
5013 * ChangeLog-threads: log from old 'threads' directory.
5014 * Makefile.in, configure: Rebuilt.
5016 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
5018 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
5021 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
5023 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
5025 Merge GH interface library into libguile.

5027 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
5028 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
5029 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
5031 (EXTRA_libguile_la_SOURCES): ... here.
5032 (pkginclude_HEADERS): Add variable, to get gh.h installed.
5033 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
5034 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
5035 New variables, describing how to build the gh test programs.
5036 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
5037 build the test programs, and we probably should have been linking
5038 libguile.la against them all along, to support AIX shared libs.
5039 Add cflags for threads to CFLAGS; add libs for threads to new
5040 variable THREAD_LIBS, used in Makefile.am.
5041 * ChangeLog-gh: log from old `gh' subdirectory.
5042 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
5044 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
5046 * acconfig.h: Undo change of Apr 9; including the definition of
5047 PACKAGE in the guile headers conflicts with applications' own
5049 * scmconfig.h.in: Regenerated.
5051 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

5060 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
5062 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
5063 have S_IFSOCK. This is the case under Ultrix.
5065 * posix.c (scm_status_exit_val, scm_status_exit_val,
5066 scm_status_term_sig, scm_status_stop_sig): Modified to work with
5067 Ultrix versions of WIFSTOPPED, etc., which assume that their
5068 arguments are lvalues (hmm).
5070 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
5072 * eval.c: Doc fixes.
5074 * throw.c: Doc fixes; rearranged.
5076 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.

5080 * acconfig.h: Added entry for PACKAGE.
5081 * scmconfig.h.in: Regenerated.

5084 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
5085 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
5087 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
5089 * Makefile.in: Rebuild.
5091 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5093 * stime.c (scm_mktime): take an optional zone argument.
5094 (scm_localtime): check putenv return value.
5095 (scm_strftime, scm_strptime): moved from posix.c. move #include
5097 stime.h, posix.h: update prototypes.
5098 (bdtime2c, setzone, restorezone): new static procedures.
5099 (scm_mktime, scm_strftime): use them.
5100 (scm_strftime): don't call mktime before strftime. Use
5101 filltime for return value.
5102 (filltime): convert NULL zname to #f.
5103 (scm_strptime): return a count of characters consumed, not
5104 the remaining string.
5106 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5108 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
5109 (scm_mktime): likewise.
5111 Uncomment localtime and mktime.
5113 * configure.in: add AC_STRUCT_TIMEZONE.
5115 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5117 * stime.c (scm_init_stime): don't define ticks/sec.
5118 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
5119 return value problem and is still portable.)
5121 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5123 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
5124 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
5125 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
5126 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
5127 cpp_err_symbols.c): Corresponding changes.
5128 * Makefile.in: Regenerated.
5130 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5132 * posix.c (scm_putenv): don't check HAVE_PUTENV.
5133 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
5134 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
5135 * putenv.c: new file, from sh-utils 1.12.
5137 * posix.c (scm_environ): use malloc in place of scm_must_malloc
5138 since allocation isn't for Scheme objects.
5139 (scm_putenv): copy strings before placing in the environment.
5141 * stime.c (scm_current_time): throw an error if time returns -1,
5142 instead of returning #f.
5143 (scm_get_internal_real_time, scm_get_internal_real_time): use
5144 scm_long2num for return value instead of SCM_MAKINUM.
5146 * stime.h: prototypes updated.
5148 * stime.c (scm_time_in_msec): apparently unused, deleted.
5150 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5152 * configure.in: check for gettimeofday.
5154 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
5155 which may be more usefully portable than a gettimeofday interface.
5157 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
5159 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not

5163 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5165 * stime.c (filltime): recovered static procedure.
5166 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from

5170 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
5172 * posix.c (scm_mknod): split the mode argument into type and perms
5173 arguments, like the extra fields returned by stat.
5175 * fports.c (scm_pipob): set the close, free and print procedures.
5176 (scm_close_pipe): new procedure.
5178 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
5179 define them in boot-9.scm
5181 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5183 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
5184 wan't defined. Don't include fd.h.
5186 * Previously fd.h was regenerated whenever configure was run,
5187 forcing a couple of files to be recompiled.
5189 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
5190 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
5191 Check for _fileno as well as _file.
5193 * ioext.c: don't fd.h.
5194 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
5197 * Change the stratigy for getting information about errno
5198 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
5199 generating lists of symbols during the build process, which will
5200 not always work, include comprehensive lists in the distribution.
5201 To help keep the lists up to date, the "check_signals" and
5202 "check_errnos" make targets can be used.
5204 * configure.in: don't check for a command to extract errno codes.
5205 * Makefile.am: update file lists, remove errnos.list and errnos.c
5206 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
5207 check_errnos targets.
5208 (CLEANFILES): remove errnos.c and errnos.list, add
5209 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
5210 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
5211 * errnos.default: deleted.

5216 * error.c (scm_init_error): #include cpp_err_symbols instead of
5218 * posix.c (scm_init_posix): don't intern signal symbols. #include
5221 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
5223 * strop.c (scm_i_index): allow the lower bound to be equal to the
5224 length of the string, so a null string doesn't always give an error.
5226 * posix.h: new prototypes.
5227 * posix.c (scm_status_exit_val, scm_status_term_sig,
5228 scm_status_stop_sig): new functions, as in scsh. They break down
5229 process status values as returned by waitpid.
5231 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
5233 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
5234 configure doesn't know about it.
5236 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5238 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
5240 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
5241 which defines C variables with global linkage.
5243 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5245 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
5248 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
5250 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
5251 has time to check why this doesn't work well with continuations.
5253 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
5255 * Fix shell syntax error; some shells won't tolerate
5256 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
5258 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5260 * posix.c (scm_uname): throw an error if uname fails instead
5263 * error.h (scm_errno, scm_perror): obsolete prototypes removed.

5272 * acconfig.h: Removed PACKAGE.
5274 * scmconfig.h.in: Regenerated.
5276 * snarf.h: g++ says it's non-portable not to specify the first
5277 argument in a varargs declaration. I introduced the first
5278 argument by using preprocessor conditionals.
5280 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
5282 * ioext.c (scm_read_delimited_x): use RO string macros for delims.

5312 * error.h: prototype for scm_error_scm.
5314 * error.c (scm_error_scm): new procedure, reimplements scm-error
5315 in C and uses scm_error.
5317 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5319 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
5320 pointer to the Scheme variable read-hash-procedures and intern it
5321 in scm_init_read. Modify scm_read_hash_extend and
5322 scm_get_hash_procedure to use the pointer.
5324 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5326 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
5327 (SCM_KEYWORD_STYLE): defined.
5329 * read.c (scm_read_opts): add a keywords option. This isn't a
5330 boolean option, in case someone wants to add support for DSSSL
5332 Setup scm_keyword_prefix symbol.
5333 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
5335 I've left keyword support disabled by default, since it doesn't
5336 seem to break the module system and it gives R4RS standard behaviour.
5337 It can be reactivated with (read-set! keywords 'prefix).
5339 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5341 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS

5353 * read.c (scm_init_read): intitialise scm_read_hash_procedures
5354 (idea from Mikael: make it a pair so scm_permanent object only
5356 (scm_read_hash_extend): don't call scm_permanent_object.
5357 (ideas from Mikael): if chr is already in the list, replace its
5358 procedure instead of appending it again. If proc is #f, remove
5360 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
5362 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.

5377 (scm_lreadr): use scm_get_hash_procedure instead of an argument
5378 for extended # processing.
5379 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
5380 scm_read_token): remove case_i, sharp arguments. Change callers.

5389 to determine whether to convert symbol case.
5390 (default_case_i): definition removed.
5391 * read.c (scm_read_token): if case_i, downcase ic before doing
5394 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5396 * configure.in: Added configuration option `guile-debug'.
5397 Configure with --enable-guile-debug if you want a bunch of extra
5398 functions used for debugging when developing Guile.
5400 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
5402 * procs.c (make-cclo): New undocumented debugging procedure: Make
5403 compiled closure with internal procedure PROC and length LENGTH.

5406 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
5408 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
5410 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
5412 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
5413 with 3 or more args internally to the evaluator.
5415 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5417 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
5418 with 3 or more args internally to the evaluator. This is mainly
5419 because we don't want to pass entry and exit points of the
5420 debug support twice, but it also seems to increase the speed of
5421 the evaluator for such calls (e. g. (+ 1 2 3)).
5423 * backtrace.c (scm_display_application): New procedure:
5424 display-application; Set fancy printing parameters individually
5425 for different types of display (backtrace, error, application).
5426 (These should of course be customizable!)
5428 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
5429 clear the CHECK-flags.
5431 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5433 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
5435 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5437 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
5438 from pairs with a GLOC in the car.
5440 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
5441 otherwise `symbol-hash' will behave badly.
5442 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
5443 we get segmentation fault!
5445 * symbols.c: Added #include "weaks.h". New functions:
5446 `builtin-bindings' and `builtin-weak-bindings'. (These will be
5447 moved to an extraneous library when we split libguile.)
5449 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5451 * filesys.c (scm_stat): stat now takes fport arguments too as
5452 documented in the manual.
5454 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5456 * debug.c (scm_single_step): Bugfix: Call continuation with
5457 scm_call_continuation instead of throwing to it.
5459 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
5461 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
5462 argument wasn't declared to be optional.
5464 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5466 * stime.c (scm_init_stime): Add feature "current-time".
5468 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5470 * throw.h: prototype for scm_exit_status.
5471 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
5472 args to derive an exit status. Allows (quit) to work from a
5474 (scm_exit_status): new function.
5477 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5479 * eval.c (scm_deval): Removed some old code.
5480 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
5482 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
5485 * symbols.c (msymbolize): Bugfix: Must initialize property list to
5488 * procs.c: Introduce the existent C function scm_thunk_p at the
5489 Scheme level as well.
5491 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5493 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
5494 used from C to easily lookup the value of a symbol in the current
5497 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5499 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
5500 scm_init_unif in this file. This will also fix a previous problem
5503 * configure.in: Added AM_MAINTAINER_MODE
5505 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5507 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
5510 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5512 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
5513 source files that are not always included in libguile but should
5514 have their dependencies calculated by automake. This variable is
5515 recognized by automake, no further magic is needed.
5516 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
5517 to deal exclusively with *.lo files, as it seems. The *.o files
5518 are built automatically when the corresponding *.lo file gets
5521 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
5523 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
5526 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
5528 * unif.c (scm_array_set_x): minor change to argument error checking.
5530 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
5532 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
5533 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
5534 They should only be included in the library at configure.in's
5536 (libguile_la_LDADD): Include the appropriate .lo files here.
5537 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
5538 so we know when to build them (and their .lo bretheren).
5539 * configure.in (LIBLOBJS): New substituted variable. We let
5540 configure decide which .o files to include in LIBOBJS, and then
5541 put the corresponding list of .lo files in LIBLOBJS. The latter
5542 is what we pass to libtool.
5543 * Makefile.in, configure: regenerated.
5545 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
5547 * symbols.c (scm_sysintern0): New function. Contains the core of
5548 old scm_sysintern but doesn't take a second value argument.
5549 (scm_sysintern): Now uses scm_sysintern0.
5550 (scm_sysintern_no_module_lookup): Renamed to
5551 scm_sysintern0_no_module_lookup and doesn't take a second value
5552 argument any longer.
5554 * symbols.h (scm_sysintern0: Added declaration.
5556 * options.c (scm_init_opts): Use scm_sysintern0 instead of
5557 scm_sysintern when interning option keys. Otherwise we risk
5558 destroying the values of already interned variables.
5560 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
5561 scheme-level boolean (use SCM_NFALSEP).
5563 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
5565 (scm_backtrace): New function. (C version of old function from
5566 boot-9.scm) Motivation: Make it possible to display backtraces
5567 without depending on boot-9.scm. (I'm uncertain if this
5568 motivation is good enough...)
5570 * root.h (scm_root_state): Add member the_last_stack_var.
5571 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
5573 * root.c (mark_root): Mark scm_the_last_stack_var.
5575 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
5578 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
5580 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
5581 1. mark_lazy_catch didn't mark the smob.
5582 2. Both functions above have standard variants:
5583 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
5584 free_lazy_catch --> scm_free0.
5586 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
5588 * throw.c (scm_internal_lazy_catch): New function.
5589 (scm_lazy_catch): Rewritten to use it.
5590 (scm_ithrow): Handle the new lazy catch representation.
5591 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
5592 that doesn't have a jmpbuf is a lazy catch clause.
5593 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
5594 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
5595 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
5597 (scm_init_throw): Register the new lazy-catch smob type.
5598 * throw.h (scm_internal_lazy_catch): decl for new function.
5600 * throw.c (scm_internal_catch): Doc fixes.
5602 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
5603 configure.in. Including this might cause problems if applications
5604 that link against libguile include their own copies of alloca, but
5605 if they're using autoconf, they should be adding libguile to LIBS
5606 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
5607 the copy in libguile, and things will be okay. (I think.)
5609 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5611 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
5613 strop.h: move prototypes too.
5615 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5617 * posix.c (scm_init_posix): don't intern EINTR since it's now done
5620 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
5621 etc. I deleted them from filesys.c long ago, but didn't
5622 notice they were here too (although ineffective since
5623 sys/stat.h wasn't included).
5625 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
5627 * eval.c: Don't define alloca in GCC case. gcc will automatically
5628 use __builtin_alloca if appropriate.
5630 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5632 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
5633 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
5634 that values of automatic variables are preserved. See comments
5635 for safe_setjmp for details.
5637 Change from Thomas Morgan:
5638 * variable.c: Include eq.h.
5639 (var_equal): New function.
5640 (variable_smob): Use var_equal as the discriminator for variables.
5642 * throw.c (s_throw): Remove extraneous declaration.
5644 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
5645 * eval.c: Add necessary CPP cruft to support that.
5646 * configure, Makefile.in, scmconfig.h.in: regenerated.
5648 Change from Thomas Morgan:
5649 * procprop.c (scm_procedure_properties): Convert the Scheme
5650 boolean returned by scm_procedure_p into a C boolean before using
5651 it as a condition for SCM_ASSERT.
5652 (scm_procedure_property): Likewise.
5654 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
5655 indications of Unixness.
5658 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5660 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
5662 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5664 * read.c (scm_lreadr): use scm_misc_error to improve one of the
5665 "unknown # object" error messages.
5667 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
5668 (scm_i_index) and declare it static. Add a 'direction' argument
5669 to indicate what way the search should go.
5670 (scm_i_index): throw out-of-range error instead of wrong-type-arg
5672 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
5673 strop.h: remove scm_i_index, scm_i_rindex prototypes.
5675 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5677 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
5679 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
5680 to avoid clash with various scsh forks.
5682 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
5684 The following two changes (ramap.c, throw.c) are motivated by the
5685 apparent unportability of forward declarations of static arrays of
5686 the form `static foo bar[];'.
5688 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
5689 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
5691 * throw.c (scm_throw): Moved above scm_ithrow.
5693 * options.h: Removed the extern declarations of scm_yes_sym and
5694 scm_no_sym since these are static.
5696 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5698 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
5700 * Makefile.am: remove AWK=@AWK@.
5701 Add a rule for generating errnos.list.
5702 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
5704 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
5705 don't extract errnos, just set a variable (avoids the
5706 need to recompile error.c just because configure is run.)
5708 * unif.h: update prototypes.
5709 * unif.c (scm_uniform_array_read,write): change the offset and
5710 length arguments to start and end, for consistency.
5712 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
5714 * ioext.h: update prototypes.
5715 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
5716 scm_read_line_x, it's a more general procedure using an
5717 interface from scsh. read-line and read-line! are now defined
5719 Note that the new read-line trims the terminator
5720 by default, previously it was appended to the returned string. An
5721 optional argument specifies how to process the terminator (scsh
5722 compatible). For the old behaviour: (read-line port 'concat).
5723 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
5724 returns a pair, but is converted to multiple values if the scsh
5727 socket.h: update prototypes.
5728 * socket.c (scm_recvfrom): for consistency with other procedures,
5729 take start and end as separate optional arguments.
5730 (scm_recv, scm_recvfrom): don't allow the second argument
5731 to be a size, only a buffer. Change the scheme names to
5732 recv! and recvfrom!. Don't return the buffer.
5734 * ioext.h, posix.h: move prototypes too.
5735 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
5736 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
5737 "read.h" and "unif.h".
5738 * ioext.c: include "chars.h"
5740 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
5742 * dynl.c: The dynamic linking and module registration functions
5743 are now defined even when dynamic linking is not available for the
5744 host system. Some of their functionality can be done without
5745 dynamic linking; when it's really needed, they throw errors.
5747 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
5749 * configure.in: Only define DYNAMIC_LINKING when one of the system
5750 dependent functions is detected.
5751 * dynl.c (scm_dynamic_func): New function to get the address of a
5752 function in a dynamic object.
5753 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
5754 produced by scm_dynamic_func as the thing to call.
5756 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
5758 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
5759 (scm_register_module_xxx, scm_registered_modules,
5760 scm_clear_registered_modules): New functions.
5762 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
5764 * symbols.c (scm_sysintern): Renamed to
5765 scm_sysintern_no_module_lookup.
5766 (scm_sysintern): New function to take the place of the old
5767 scm_sysintern. It uses the current toplevel lookup closure to give
5768 the symbol its value. This is a temporary hack to put packages
5769 like gtcltk into their own module.
5770 (scm_can_use_top_level_lookup_closure_var): New variable to tell
5771 us whether `scm_top_level_lookup_closure_var' has been initialized
5773 * eval.c (scm_init_eval): Set it.
5775 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5777 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
5778 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
5780 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
5782 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
5783 scm_sys_dup): deleted: FD capability will be added to other
5785 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
5786 scm_fd_free, fd_smob, scm_intern_fd.
5787 (scm_open): renamed from scm_sys_open. Return a port instead of
5788 an FD object. Make the mode argument optional.
5789 (scm_sys_create): deleted, it's just a special case of open.
5790 (scm_init_filesys): move interning of constants O_CREAT etc.,
5791 here (were previously using SCM_CONST_LONG macro).
5792 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
5794 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
5795 include "fports.h" and <stdio.h>
5796 (scm_stat, scm_select): don't support FD objects.
5798 * error.h: adjust scm_syserror_msg prototype.
5799 * error.c (scm_syserror_msg): take an extra argument for errno.
5800 Using the global value didn't always work, since it could be
5801 reset by procedure calls in the message or args arguments.
5803 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
5804 I don't understand why the check was there (and what about the
5807 * strop.c (scm_string_copy): allow shared substrings to be copied.
5809 * unif.h: corresponding change to prototypes.
5810 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
5811 recognize two new optional arguments: offset and length. Allow
5812 the port argument to be an integer (file descriptor, for scsh).
5813 Include <unistd.h> for "read" prototype.
5815 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5817 * socket.c: don't include filesys.h.
5819 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
5821 * Makefile.am: add AWK=@AWK@ (?)
5823 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
5825 Add a rule to generate errnos.c from errnos.
5826 * error.c (scm_init_error): include errnos.c.
5827 * errnos_cnvt.awk: new file, converts the list of errno codes to
5829 * errnos_get.c: new file.
5830 * errnos.default: new file, contains errnos to try if they can't
5831 be extracted from errno.h.
5832 * configure.in: if using GCC, try and extract errno codes from
5836 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
5838 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
5839 * Makefile.am: Made libguile into a libtool library.
5840 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
5841 Set libtool_libs to indicate that libguile is a libtool library.
5842 See guile/ChangeLog for details.
5843 * .cvsignore: ignore "*.lo", the libtool library objects.
5845 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5847 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
5848 use htons in getservbyport argument.
5850 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5852 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
5853 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
5856 * objprop.c (scm_object_property): No need to take the CDR of the
5857 value returned by scm_object_properties, since Aug 20 change.
5859 * configure.in: When checking for struct linger, #include
5860 <sys/types.h> as well as <sys/socket.h>. I've never known
5861 <sys/types.h> to cause any portability problems, and Solaris's
5862 <sys/socket.h> needs it.
5863 * configure: Rebuilt.
5865 I think the Sun compiler has chosen a perverse way to interpret
5866 ANSI declarations combined with K&R definitions. We'll
5867 appease it a little bit. But when it invades France, we fight.
5868 * print.c (scm_iprlist): Change 'tlr' argument to an int.
5869 * print.h (scm_iprlist): Here too.
5870 * numbers.c (scm_divbigdig): Change definition to match
5871 declaration in numbers.h.
5872 * unif.c (scm_makflo): Change definition to match declaration in
5875 * init.c (scm_boot_guile): Don't return the value of
5876 scm_boot_guile_1. This function doesn't return a value;
5877 scm_boot_guile_1 doesn't return a value (or return at all).
5879 * eval.c (unmemocopy): Add a semicolon to appease the Sun
5882 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
5883 compile. I have a feeling this function is a bad idea anyway ---
5884 one should always test for features, not systems.
5886 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
5887 semicolons. Only pure luck kept this from being noticed earlier.
5889 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
5891 * socket.c (scm_recvfrom): Added missing semicolon.
5893 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5895 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
5896 the buffer and start and end positions for scsh networking
5899 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
5901 * configure.in: Revert previous change to this file; the problem
5902 is due to transient automake weirdness.
5903 * configure: Rebuilt.
5905 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
5906 PLUGIN/guile.libs. configure generates the latter from the former.
5907 * Makefile.in: Rebuilt.
5909 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
5910 need this if we install scripts, like guile-snarf.
5911 * configure: Rebuilt.
5913 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5915 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
5917 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
5919 * socket.c (scm_addr_vector): fix faulty scm_listify.
5921 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
5923 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
5924 style block comment is no longer considered an error.
5926 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
5928 * PLUGIN/guile.libs.in: New file.
5929 * PLUGIN/guile.libs: Removed from repository.
5930 * configure.in: Create PLUGIN/guile.libs from
5931 PLUGIN/guile.libs.in. This is for including additonal libraries
5932 needed for dynamic linking.
5933 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
5934 instead of PLUGIN/guile.libs.
5936 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
5938 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
5940 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
5941 occurrences of the given element from the list, not just the
5942 first. This is how the Emacs Lisp functions behave, how the
5943 analogous Common Lisp functions behave, and (I believe) how the
5944 older Maclisp functions worked. I realize that this change may
5945 break code, but it seemed better to break it before the Guile
5948 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
5949 Their prototypes were already present in gc.h, but they weren't
5951 (scm_init_storage): Initialize scm_protects.
5952 * root.c (scm_protects): New element of scm_sys_protects.
5954 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
5956 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
5958 * libguile.h: Added #include "libguile/net_db.h".
5960 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
5961 30 change. That file is only meant for communication between the
5962 configuration process and load.c. If code linked against libguile
5963 wants to get at the paths mentioned in libpath.h, it can call
5964 functions declared in load.h.
5966 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5968 * libguile.h: Removed #include "libguile/fdsocket.h"
5970 * net_db.c: Added #include <sys/socket.h>.
5972 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
5974 * filesys.c (scm_input_waiting_p): use select in preference to
5975 FIONREAD, since the latter doesn't detect EOF.
5976 Throw error if neither select nor FIONREAD available.
5978 * socket.c (scm_connect): take a port, not a fd object.
5979 (scm_fill_sockaddr): throw an error if fam is not recognised.
5980 (scm_bind): use scm_fill_sockaddr.
5981 (scm_listen): take a port, not a fd object.
5982 (scm_accept): take and return a port. return #f in the car if
5983 address can't be got
5984 (scm_sock_fd_to_port): new procedure.
5985 (scm_socket): use scm_sock_fd_to_port.
5986 (scm_addr_vector): throw error if unrecognised address type.
5987 take an extra argument with the calling procedure name.
5988 (scm_getsockname): take a port. return #f if address can't be got.
5989 (scm_getpeername): take a port. return #f if address can't be got.
5990 (scm_recvfrom): take a port. return #f for address component if can't
5992 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
5993 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
5995 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
5997 * throw.c (scm_internal_catch): Make body funcs and handler funcs
5998 use separate data pointers, to allow them to be designed
5999 independently and reused.
6000 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
6001 Renamed from catch_body, catch_handler, and uncaught_throw; made
6003 (struct scm_catch_body_data): Renamed from catch_body_data; moved
6005 (scm_catch): Use the above.
6006 (scm_throw): Don't bother printing a message for an uncaught
6007 throw; we establish a default handler in init.
6008 * throw.h (scm_internal_catch): Prototype updated.
6009 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
6011 (struct scm_body_thunk_data): New structure, used as data
6012 argument to scm_body_thunk.
6013 * init.c (struct main_func_closure): New structure, packaging up
6014 the data to pass to the user's main function.
6015 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
6016 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
6017 scm_internal_catch to establish a catch-all handler, using
6018 scm_handle_by_message. This replaces the special-case code in
6020 (invoke_main_func): Body function for scm_internal_catch; invoke
6021 the user's main function, using the main_func_closure pointer to
6022 decide what to pass it.
6023 * root.c (struct cwdr_body_data): Remove handler_proc member.
6024 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
6025 (cwdr_handler): Removed.
6027 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6029 * socket.h (SCM_P): update bind prototype.
6030 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
6031 include "feature.h".
6032 (scm_socket): return a port, not a file descriptor object.
6033 include "fports.h" and <unistd.h>
6034 (scm_bind): take a port, not a file descriptor object.
6035 take an extra argument for address args.
6037 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
6038 INADDR_NONE, INADDR_LOOPBACK.
6040 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6042 * init.c: include net_db.h and not fdsocket.h.
6043 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
6045 * Makefile.am: corresponding changes.
6046 * socket.h: renamed from fdsocket.h, fix names.
6047 * net_db.h: renamed from socket.h, fix names.
6048 * socket.c: renamed from fdsocket.c.
6049 remove _sys from procedure names.
6050 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
6051 add "socket" to features list.
6052 * net_db.c: renamed from socket.c.
6053 remove _sys from procedure names.
6054 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
6055 add "net-db" to features list.
6056 include "net_db.h". don't include <sys/socket.h> or
6059 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6061 * tags.h (scm_tags): Removed comma at end of last enumerator.
6063 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
6065 Don't use GCC extensions to allocate space for debugging frames.
6066 (Here he goes again! Why do we put up with this?!)
6067 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
6068 an scm_debug_info structure, not an in-line array of them. Add
6069 'info' member, to say how many vect elements we've used, for eval
6071 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
6072 a new variable debug_info_end to mark the end of vect, instead of
6073 the address of the 'info' pointer itself.
6074 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
6075 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
6076 (SCM_APPLY): Explicitly allocate space for debug.vect.
6077 * debug.c (scm_m_start_stack): Same, for vframe.vect.
6078 * stacks.c: Adjusted for new debug frame structure.
6079 (RELOC_INFO, RELOC_FRAME): New macros.
6080 (stack_depth, read_frames): Use them, and new scm_debug_frame
6081 element 'info', instead of magically knowing that eval frames have
6082 an info pointer sitting after vect.
6083 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
6085 (scm_init_stacks): Formatting tweaks.
6087 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
6089 Give GCC more control flow information, so it can be sure that
6090 variables aren't used uninitialized.
6091 * error.h (scm_error, scm_syserror, scm_syserror_msg,
6092 scm_sysmissing, scm_num_overflow, scm_out_of_range,
6093 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
6094 scm_misc_error): Tell GCC that these functions never return.
6095 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
6096 out the field type, call abort if SCM_ASSERT returns, to placate
6098 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
6099 scm_wta ever returns. We can't handle this case anyway, and this
6100 gives the optimizer more information.
6101 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
6102 scm_wta ever returns.
6104 In some cases, the code is fine, but GCC isn't smart enough to
6105 figure that out; this usually happens when one variable is only
6106 initialized and used when a particular condition holds true, and
6107 we know that condition will never change within a given invocation
6108 of the function. In this case, we simply initialize the variables
6109 to placate the compiler, hopefully to a value which will cause a
6110 crash if it is ever actually used.
6111 * print.c (scm_iprin1): Initialize mw_pos.
6112 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
6113 * throw.c (scm_ithrow): Initialize dynpair.
6114 * unif.c (scm_uniform_vector_ref): Initialize cra.
6115 * struct.c (init_struct): Initialize prot.
6116 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
6118 * strports.c (scm_eval_0str): Don't return uninitialized garbage
6119 if EXPR contains no expressions.
6121 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
6123 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
6124 cause an infinite loop (???). So much for the algebraic
6125 equivalency of variable-sized arrays and alloca...
6127 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
6129 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
6130 a SCM boolean, not a C boolean.
6132 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
6134 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
6135 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
6136 rules for raising scm_mtrigger. Previously, unfortunate but not
6137 unlikely circumstances could result in almost constant invokation
6138 of the gc. Now, this situations should be less likely, but they
6139 are not prevented completely.
6141 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
6143 * numbers.c (scm_fuck): Procedure removed; looks like old test
6145 * numbers.h: Prototype removed.
6147 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
6149 * debug.h (scm_debug_frame): Change `vect' member from an in-line
6150 array to a pointer, to match my Nov 21 change in eval.c.
6152 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6154 * libguile.h: Added #include "libguile/backtrace.h", #include
6155 "libguile/stacks.h".
6157 * strings.c (scm_string scm_make_string scm_string_ref
6158 scm_string_set_x scm_string_equal_p scm_string_append):
6159 Bugfix according to scm patch from Aubrey Jaffer:
6160 Corrected long-standing
6161 (not (eqv? (integer->char 128)
6162 (string-ref (make-string 1 (integer->char 128)) 0)))
6163 bug found by John Kozak <jk@noontide.demon.co.uk>.
6165 * strports.c, strports.h: Make scm_eval_0str return the value of
6166 the last expression evaluated (previously, it returned void).
6168 * strports.c, strports.h: New function: scm_read_0str. Does what
6171 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6173 * simpos.c (scm_getenv): return #f if string can't be found in the
6174 environment instead of throwing an exception, for compatibility
6175 with numerous other systems.
6177 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
6179 * Makefile.am (.c.x): Use guile-snarf.
6180 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
6182 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
6184 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6186 * backtrace.c (scm_display_error_message): Made non-static, and
6187 renamed from display_error_message.
6188 * backtrace.h (scm_display_error_message): Added extern decl.
6189 * throw.c (uncaught_throw): Use it to display the error message.
6191 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
6193 * inet_aton.c: Use #if 0, not #ifdef 0.
6195 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
6197 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
6198 to convert the returned value.
6199 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
6200 the offset argument.
6202 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6204 Add new interface to catch/throw, usable from C as well as
6206 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
6207 (scm_internal_catch): New function, replaces...
6208 (scm_catch_apply): Deleted.
6209 * throw.c (scm_catch_apply): Deleted; replaced with a more general
6210 mechanism which is a bit more code, but can be used nicely from C
6211 and implement the Scheme semantics as well.
6212 (scm_internal_catch): This is the replacement; it's named after
6213 the analogous function in Emacs.
6214 (scm_catch): Reimplemented in terms of the above.
6215 (struct catch_body_data, catch_body, catch_handler): New
6216 functions, used by scm_catch.
6217 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
6218 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
6219 support for new cwdr.
6221 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
6224 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
6226 * acconfig.h: Added DYNAMIC_LINKING symbol.
6227 * configure.in: Add option and checks for dynamic linking.
6228 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
6229 dynl.h: New files for dynamic linking support.
6230 * Makefile.am (libguile_a_SOURCES):
6232 (modinclude_HEADERS): Added "dynl.h".
6233 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
6235 * init.c (scm_boot_guile_1): Call
6236 scm_init_dynamic_linking to initialize dynamic linking support.
6238 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
6240 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
6241 (as we Schemers say). It needs to be global, so that I can tweak
6242 it for the proper operation of unexec.
6243 (scm_boot_guile_1_live): New variable, see above.
6245 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
6247 * guile-snarf.sh: Removed.
6248 * PLUGIN/guile.libs: Added dependency for -lm.
6249 * acinclude.m4: Renamed from aclocal.m4.
6250 * PLUGIN/greet: Removed.
6251 * Makefile.am, aclocal.m4: New files.
6252 * configure.in: Updated for Automake.
6254 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
6256 * eval.c (scm_definedp): Use top_level_lookup_closure_var
6257 and not top_level_lookup_thunk_var.
6259 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
6261 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
6263 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
6265 * eval.c (scm_definedp): Incompatibly changed to be a builtin
6266 Scheme function, instead of syntax. Single argument is now a
6269 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
6271 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
6272 scm_ra_divide): Properly terminate statements passed as arguments
6273 to IVDEP macros. (Thanks to Bernard Urban.)
6275 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
6276 with non-constant sizes. (Thanks to Bernard Urban.)
6278 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6280 It's an "eval closure", not an "eval thunk." A thunk is a
6281 function of no arguments.
6282 * root.h (struct scm_root_state): Renamed
6283 top_level_lookup_closure_var from top_level_lookup_thunk_var.
6284 (scm_top_level_lookup_closure_var): Renamed from
6285 scm_top_level_lookup_thunk_var.
6286 * root.c (mark_root): Uses changed.
6287 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
6288 * init.c (scm_start_stack): Uses changed.
6289 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
6290 Change scheme-visible name to *top-level-lookup-closure* from
6291 *top-level-lookup-thunk*.
6293 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
6295 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
6296 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
6298 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
6300 * gc.c (struct scm_heap_seg_data): Doc fixes.
6302 * gc.c (scm_gc_sweep): Empty all segments' freelists before
6303 sweeping. Then, prepend each segment's free cells to its
6304 freelist, rather than wiping out the old value. (Thanks to Marius
6307 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
6308 scm_check_freelist, scm_debug_newcell): New functions and
6309 variables, for debugging freelist problems.
6310 * pairs.h (SCM_NEWCELL): New debugging version added.
6311 * gc.h (scm_debug_newcell): Added extern declaration, used by
6312 debugging version of SCM_NEWCELL.
6314 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
6316 On some systems <libc.h> conflicts with <unistd.h>, and should not
6317 be #included at all.
6318 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
6319 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
6320 * configure.in: Call it.
6321 * posix.c, filesys.c: Use its results to decide whether or not to
6323 * configure, scmconfig.h.in: Rebuilt with autoconf and
6326 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
6328 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
6329 pointer to the stdio stream before calling scm_setbuf0, so the
6330 latter will be able to retrieve it. I'm surprised this didn't
6331 segfault earlier. (Thanks to Christopher Lee.)
6333 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6335 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
6338 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6340 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
6341 number of stack narrowing specifier pairs. The first specifier in
6342 a pair controls inner border, the second the outer border. A
6343 number means cut that number of frames, a procedure object means
6344 cut until that object is found in operator position in a frame.
6346 * root.c (cwdr): Bugfix.
6348 * read.c: Recording of positions disabled by default.
6350 * procs.c (scm_closure_p): New function.
6352 * posix.c (scm_tmpnam): New function.
6354 * load.c: Added #include "throw.h".
6355 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
6358 * load.c, load.h (scm_read_and_eval_x): New function.
6360 * eval.c: Renamed debug option "deval" to "debug".
6362 (scm_eval_x): `eval!' is no longer accessible from the scheme
6363 level. Motivation: We can't allow operations which introduce
6364 glocs into the scheme level. Guile's type system can't handle
6365 these as data. Use `eval' or `read-and-eval!' as replacement.
6367 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
6368 SCM_CONSP since this is a macro!; Set vframe.prev to
6369 scm_last_debug_frame instead of 0. In this way we can look
6370 "above" the virtual start stack frame if we wish.
6371 (scm_debug_hang): New function: Useful for debugging Guile in
6372 certain tricky situations. Will probably be removed later...
6374 * debug.h: Changed semantics of debug option "backtrace". This
6375 option now only indicates whether we want automatic backtrace at
6378 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6380 * ports.c: #include "filesys.h"
6381 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
6383 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
6384 Motivation: This is system specific code which is related to file
6385 I/O. It also may use select. Added code by Gary Houston to
6386 detect presence of character in stdio buffers.
6388 * libguile.h: #include "libguile/libpath.h"
6390 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
6391 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
6392 SCM_SITE_DIR; Install libpath.h among the other include files.
6394 * load.c, load.h (scm_sys_package_data_dir): New function.
6396 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6398 * stacks.h: Bugfix: Don't use tail-array length field as stack
6399 length field! This screwed GC.
6401 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6403 * _scm.h: Added #ifndef around definition of macros min and max.
6405 * __scm.h: Added hooks for threads to plugin to in ints protection
6406 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
6407 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
6408 the main code in these macros duplicated and spread over multiple
6409 files. Renamed SCM_THREADS_SWITCHING_CODE ->
6410 SCM_THREAD_SWITCHING_CODE.
6412 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
6414 * snarf.h: New file.
6415 * guile-snarf.sh: New file.
6416 * Makefile.in (inner_h_files): Added snarf.h
6417 (ancillary, install, uninstall, distclean): Added actions for
6419 (.c.x): Use guile-snarf.
6420 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
6421 (gen_c_files): Note that these depend on guile-snarf.
6422 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
6423 now in "snarf.h". Added #include "snarf.h" to get them.
6424 * libguile.h: Added #include "snarf.h".
6425 (Patches applied and tweaked by Jim Blandy.)
6427 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6429 * socket.c: Use K&R style declaration for 'close'; the GNU coding
6430 standards suggest against providing prototypes for system
6431 functions. Thanks to Greg Troxel.
6433 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6435 * strports.c (scm_eval_0str): New function.
6436 #include "read.h", to get prototype for scm_read.
6437 * Makefile.in (strports.o): Update dependencies.
6438 * strports.h: New prototype.
6440 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
6441 scheme name from "int?" to "integer?". It seems to do the job.
6442 * numbers.h: Rename prototype too.
6443 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
6446 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
6447 scm_num_eq_p): Rename these according to R4RS conventions: call
6448 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
6449 to making libguile R4RS compliant without ice-9...
6451 * load.c (scm_sys_search_load_path): Search for files under all
6452 extensions listed in the %load-extensions variable. If FILENAME
6453 is absolute, return it unchanged, without searching the load path.
6454 (scm_loc_load_extensions): New variable, pointing to
6455 %load-extensions' value cell.
6456 (scm_init_load): Initialize it, and the value it points to.
6457 (scm_primitive_load_path): Improve error reporting.
6459 * load.c (scm_loc_load_hook): New variable, pointing to value cell
6460 of new Scheme variable %load-hook.
6461 (scm_primitive_load): Apply %load-hook to filename.
6463 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
6465 * configure.in: add tests for figuring out whether buffered data
6466 is available in a FILE structure, which is needed by char-ready.
6468 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
6471 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
6472 exceptions using misc_error instead of syserror. It seems a bit
6473 odd to throw an exception if a string can't be found in the
6474 environment, but it's consistent with open-file, stat etc.
6475 (simpos.h): remove sys_ from getenv.
6477 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
6478 occurs, throw an error instead of returning errno. Return value
6480 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
6482 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
6484 * filesys.c (scm_stat2scm): derive file type and permissions from
6485 the stat mode and append them to the returned vector.
6486 There isn't much overhead in doing this and it avoids the need to
6487 work with S_IRUSR et al. in Scheme.
6488 Define symbols scm_sym_regular etc.
6489 (scm_init_filesys): don't intern S_IRUSR etc.
6491 * load.c: change s_try_load and s_try_load_path to s_primitive_load
6492 and s_primitive_load_path.
6494 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
6496 * error.h: don't declare error symbols. prototype for scm_misc_error.
6498 * stackchk.c (scm_stack_overflow_key): defined here instead of in
6501 * error.c: use SCM_SYMBOL to set up error keys.
6502 scm_misc_error: new procedure.
6504 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
6506 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
6507 between `#!' and `!#' is ignored.
6508 (skip_scsh_block_comment): New function.
6510 * feature.c (scm_set_program_arguments): New argument, FIRST.
6511 * feature.h: Update prototype.
6512 * init.c (scm_boot_guile_1): Pass new argument to
6513 scm_set_program_arguments.
6515 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6517 * init.c (scm_start_stack): Don't initialize scm_progargs here.
6518 (scm_boot_guile): Call scm_set_program_arguments here, later than
6519 the old initialization.
6521 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
6522 initialization procedure.
6523 - Delete in, out, err arguments; there are other perfectly good
6524 ways to override these when desired.
6525 - Delete result argument; this function shouldn't ever return.
6526 - Rename init_func argument to main_func, for less confusion.
6527 - Delete boot_cmd argument; main_func is more general.
6528 -Add 'closure' argument, to help people pass data to main_func
6529 without resorting to global variables.
6530 - Abort if reentered; don't bother returning an error code.
6531 - Call scm_init_standard_ports to set up the default/current
6532 standard ports; no need to pass them to scm_start_stack.
6533 - Remove code to evaluate the boot_cmd, and start the repl; let
6534 the user do something like that in main_func if they want.
6535 - Remove code to package up a return value; main_func can do any
6537 - Call exit (0), instead of returning.
6538 (scm_start_stack): Don't initialize the I/O ports here; that's
6539 weird. Delete in, out, err arguments. Move guts to
6540 scm_init_standard_ports, scm_stdio_to_port.
6541 (scm_init_standard_ports): New function, to set up current and
6542 default standard ports.
6543 (scm_start_stack, scm_restart_stack): Make these static.
6544 * init.h (scm_boot_guile): Adjust declaration.
6545 (scm_start_stack, scm_restart_stack): Remove externally
6546 visible declarations for these.
6547 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
6549 * fports.c (scm_stdio_to_port): New function. Its guts used to be
6550 written out several times in scm_start_stack.
6551 * fports.h: New declaration for the above.
6553 * feature.c (scm_set_program_arguments): New function.
6554 * feature.h: New declaration for the above.
6556 * ports.c: Formatting tweak.
6558 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
6560 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
6561 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
6562 for obtaining the address of a car or cdr field. Motivation:
6563 &SCM_CXR make assumptions about the internal structure of the
6566 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
6567 Motivation: see SCM_CXRLOC.
6569 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
6570 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
6571 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
6572 Motivation: Safer use. Some other macros are defined in terms of
6573 these operations. If these are defined using the SCM_SETCXR
6574 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
6575 to inefficiency and an <e1> with side-effects could potentially
6576 break. Also, these particular operations are heavily utilized in
6577 the garbage collector. In unoptimized code there will be a
6580 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
6581 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
6582 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
6583 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
6584 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
6585 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
6586 vports.c: Cleaned up use of pairs: Don't make any special
6587 assumptions about the internal structure of selectors and
6588 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
6589 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
6590 (Among other things, this change makes it easier to build Guile
6591 with certain compilers which have problems with casted lvalues.)
6593 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6595 * stacks.c: Improve selection of relevant stack frames when making
6596 a stack object. Introduce one level of indirection in the stack
6597 object to make it possible to "narrow" to a certain region of the
6598 stack. This facilitates making use of more clever algorithms (not
6599 implemented) for selecting relevant frames and gives a cleaner
6600 design since selection of frames can be done independently of
6601 extraction of frames from the real stack.
6602 (scm_stack_id): Also take #t as argument which means look at
6605 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
6606 Turn n_tail into an integer directly representing current number
6607 of frames in stack. Add field tail.
6609 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
6611 * debug.c (scm_make_memoized): Made it available at scheme level.
6612 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
6613 SCM_NIMP before applying heavier predicates in argument checking.
6614 (scm_local_eval): Also take memoized object as argument.
6616 * backtrace.c (scm_display_error): Just a safety measure: Stacks
6617 aren't created with zero length, but should such a strange
6618 creature suddenly turn up...
6620 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
6622 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
6623 `del', for the sake of C++ compilers. (Patch applied by JimB.)
6625 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
6627 * variable.c (scm_make_variable): Make the name hint optional, as
6629 (anonymous_variable_sym): Renamed from variable_sym. All uses
6632 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
6633 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
6634 of scm_primitive_load_path was also changed to
6635 "primitive-load-path", from "%try-load-path". Callers changed.
6636 We'd like to respect the convention that a function named
6637 "try-mumble" should behave just like the function called "mumble",
6638 but return #f instead of signalling some error.
6639 * load.h: Rename prototypes.
6641 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6643 * print.c (make_print_state, grow_print_state), print.h: Modified
6644 the print state representation: Don't use a tail array for
6645 recording of circular references. Resizing of the print state
6646 structure invalidates the print state pointer. To avoid passing
6647 around an indirect print state reference to all printing
6648 functions, we instead let the print state reference a resizable
6651 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
6653 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
6654 Don't crash when passed an improper list terminated by a
6655 non-immediate value.
6657 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
6659 Allocate data for structures on an eight-byte boundary, as
6660 required by the tagging system.
6661 * struct.c (alloc_struct): New function.
6662 (scm_make_struct, scm_make_vtable_vtable): Call it.
6663 * struct.h (scm_struct_n_extra_words): Bump to 3.
6664 (scm_struct_i_ptr): New "field".
6665 * gc.c (scm_gc_sweep): When we need to free the data, use the
6666 information stored by alloc_struct to find the beginning of the
6667 block allocated to the structure, so we can free it.
6669 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6671 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
6674 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
6675 (scm_debug_info): New member: id.
6677 * stacks.c: Stacks are now represented as structs; Stacks have an
6678 id given to them by `start-stack'.
6679 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
6681 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
6682 Changed stack representation.
6684 * debug.c (scm_procedure_name): Try procedure property `name' for
6685 compiled closures aswell.
6687 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
6689 * eval.c: scm_i_name moved to gsubr.c
6690 (scm_m_define): Record names of all kinds of procedure
6691 objects. (Earlier, only closures were recorded.)
6693 * procprop.h: Added declaration of scm_i_name.
6695 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
6696 (scm_make_gsubr): Record names of compiled closures.
6698 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6700 * debug.c, debug.h: Removed obsolete code.
6702 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
6703 stacks.c: Renamed regs --> scm_contregs.
6705 * print.c (scm_free_print_state): Cleanup print state before
6706 returning it to pool. It is better to do it here than in
6707 scm_prin1 since scm_prin1 is called often.
6709 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
6710 s_set_source_property_x): Check that first argument is a pair or a
6713 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
6714 scm_i_line, scm_i_column and scm_i_breakpoint global.
6716 * init.c: Added #include "backtrace.h" and #include "stacks.h".
6717 (scm_boot_guile_1): Added calls to scm_init_backtrace and
6720 * debug.h: Added debug object smob declaration and macro
6723 * configure.in: Build with backtrace.o and stacks.o if debug
6726 * Makefile.in: Added entries for new files: backtrace.c,
6727 backtrace.h, stacks.c and stacks.h.
6729 * symbols.c (scm_sym2ovcell): Fixed documentation.
6731 * _scm.h (min, max): Added.
6733 * async.c: Moved `min' macro to _scm.h.
6735 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
6736 SCM_BACKTRACE_INDENT.
6738 * eval.c: Added new debug options `maxdepth' and `indent'.
6740 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
6742 * print.h: Added selector SCM_PRINT_STATE.
6744 * print.c: New functions: scm_make_print_state,
6745 scm_free_print_state.
6747 * print.h: Added declarations for scm_make_print_state,
6748 scm_free_print_state.
6750 * debug.c (scm_m_start_stack): New acro.
6752 * debug.h: Small cleanup.
6754 * init.c (scm_boot_guile_1): Moved scm_init_debug below
6757 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

6782 More prototype-related changes from Marius Vollmer:
6783 * gdb_interface.h: Wrapped header file in #ifdef/#endif
6784 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
6785 * ports.h (ptobfuns): Added prototypes. This means some casting in
6787 * fports.c: Added casts for initializations, since the functions
6788 are defined to take FILE * as their stream argument, not SCM.
6789 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
6790 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
6791 to `char *str_data' to conform to prototype.
6793 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
6795 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
6797 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
6799 * stime.c, stime.h: use SCM_P method.
6801 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
6803 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
6804 be given at least two arguments. Insist that lst's last element
6805 be a list, but don't make any requirements of its predecessors.

6809 * eval.c (scm_nconc2last): Revert last change; there seems to be
6810 other stuff going on here.
6812 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
6814 * eval.c (scm_nconc2last): Make sure that each element of lst
6815 (which is a list of argument lists, except for the tail) is a
6816 proper list, i.e., finite and terminated by '().
6818 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6820 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
6823 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
6824 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
6827 * vectors.c (scm_make_vector): Fill vectors with the undefined
6828 value, to help make Guile Scheme code more portable to other
6831 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
6832 * symbols.h, tags.h: Doc fixes.
6834 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
6836 * async.c (scm_take_signal): Doc fixes.
6838 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
6840 * numbers.c (scm_divbigint): When the remainder is zero, we don't
6841 want to subtract it from the modulus; we just want to leave it
6844 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
6846 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
6849 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
6851 * throw.c (scm_catch_apply): Finished implementation of
6854 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
6856 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
6858 (scm_init_filesys): set "i/o-extensions" feature.
6861 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
6863 * Makefile.in (root.o): Correct dependencies.
6865 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
6867 * Makefile.in: Added dependency entry for root.o.
6869 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
6870 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
6872 * init.c (scm_start_stack): Set initial root continuation number
6875 * procs.c: New function: scm_thunk_p.
6877 * procs.h: Added declarations of scm_thunk_p.
6879 * root.c: Renamed `call-with-new-root' -->
6880 `call-with-dynamic-root'.
6881 (cwdr): Removed allocation of new root state. This should be done
6882 separately by use of scm_make_root.
6883 (scm_apply_with_dynamic_root): New function: Does what it
6884 sounds like. Needed when spawning threads.
6886 * root.h: Added member last_debug_frame to root state.
6887 Added #include "libguile/debug.h"
6889 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
6890 arguments. The motivation is that code in root.c needs catch
6891 functionality, and we want to avoid code duplication.
6892 New functions: scm_catch, scm_lazy_catch. These are wrappers for
6893 scm_catch_apply. scm_lazy_catch is intended to introduce catch
6894 handlers that run without popping the stack into the dynwind
6897 * throw.h: Added prototypes for scm_catch_apply and
6900 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6902 * root.h (scm_root, scm_set_root): Decouple thread support details
6903 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
6904 SCM_SET_THREAD_LOCAL_DATA.
6906 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
6907 and tortoise scanning loop.
6909 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
6911 * Makefile.in: Rebuild dependencies.
6913 * libguile.h: #include "libguile/print.h" before "smob.h", since
6914 the latter uses the print_state structure.
6916 * throw.c (scm_ithrow): Use the correct variable when checking to
6917 see if a given element of scm_dynwinds is a valid catch.
6919 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
6920 structure, abort; don't just silently ignore the garbage.
6922 * _scm.h: #include "print.h" here, since it seems to be used just
6924 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
6925 strports.c, unif.h: Don't #include "print.h".
6927 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6929 * feature.h (scm_loc_features): Removed external declaration.
6930 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
6932 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6934 * feature.c (scm_init_feature): Added threads feature (needs to be
6935 initialized here, since features doesn't exist when
6936 scm_init_threads is called).
6938 * libguile.h: Added #include "libguile/../threads/threads.h".
6939 (This is a kludge to get thread support working. This should be
6942 * configure.in, acconfig.h: Added flags for thread support.
6944 * scmsigs.c: Define `signal' to be `pthread_signal' if using
6947 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
6948 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
6951 * _scm.h: Added conditional #include "threads.h"
6953 * __scm.h (SCM_ASYNC_TICK): Added call to macro
6954 SCM_THREADS_SWITCHING_CODE.
6956 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
6957 allocate the basic dynamic root object.
6958 (scm_boot_guile): Added call to scm_init_root.
6960 * root.c, root.h: Added root smob.
6961 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
6962 functions: Implements dynamic roots mostly according to spec in
6963 SCM manual. Main difference is that the second argument is a
6964 throw handler rather than an error "thunk".
6966 * root.h: Added declaration of scm_init_root.
6968 * root.c: Added #include "genio.h", #include "smob.h", #include
6969 "pairs.h", #include "throw.h", #include "dynwind.h", #include
6971 (scm_init_root): Added #include "root.x".
6973 * throw.c: Added #include "stackchk.h"
6974 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
6975 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
6976 can be used in scm_call_with_new_root; Added reenabling of stack
6977 checking when catching a throw.
6979 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
6981 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
6983 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
6984 element is not found, as per R4RS.
6986 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
6988 * list.c: Doc fixes throughout.
6990 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6992 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
6993 declare the char * to be const. Avoids a warning in rgx.c.
6995 * ports.h: spelling fix.
6997 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
7000 * load.c (scm_sys_try_load_path): throw an error if file not found
7001 (like it says it in NEWS).
7003 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7005 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
7006 PROPS slot to '(), not #f; it's an empty alist.
7008 * throw.h, throw.c: Use SCM_P instead of #if hair.
7010 Remove special support for uncaught throws; see throw.c for
7012 * throw.c (uncaught_throw): New function.
7013 (scm_ithrow): Call uncaught_throw if we don't find a throw
7014 target; don't mess with scm_bad_throw_vcell.
7015 (scm_bad_throw_vcell): Variable deleted.
7016 (scm_init_throw): Don't initialize it.
7018 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
7021 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
7023 * numbers.c (scm_istr2int): If the number is short (as most
7024 numbers are), just call scm_small_istr2int to deal with it.
7025 (scm_small_istr2int): New function, created by un-#ifdefing the
7026 non-bignum version of scm_istr2int and renaming it.
7028 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
7030 * load.c (scm_sys_try_load): don't check whether value returned
7031 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
7032 Change the Scheme name from %try-load to primitive-load.
7034 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
7035 Can avoid passing a message, allowing it to be derived in the
7036 error handler (e.g., if we want to throw to the key both from
7039 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
7041 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
7042 references now have a new appearance which is more compact and
7043 also gives a clue about what the target of the reference is.
7044 By setting parameters in the print state, more fancy printing can
7045 be achieved. This is used by the (not yet commited) backtrace
7048 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
7050 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
7053 * print.c: Added #include "struct.h". Removed function
7056 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
7057 scm_iprin1. Removed prototype for scm_prlist.
7059 * arbiters.c (prinarb),
7060 async.c (print_async),
7061 debug.c (prindebugobj, prinmemoized),
7062 eval.c (prinprom, prinmacro),
7063 filesys.c (scm_fd_print, scm_dir_print),
7065 mallocs.c (prinmalloc),
7066 numbers.c, numbers.h (scm_floprint, scm_bigprint),
7067 smob.h (scm_smobfuns),
7068 srcprop.c (prinsrcprops),
7070 unif.c, unif.h (scm_raprin1, rapr1),
7071 variable.c (prin_var): Changed argument `int writing' to
7072 `scm_print_state *pstate'.
7074 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
7075 that it will be called before scm_init_print.
7077 * print.c (scm_prin1): Print states are now allocated when calling
7078 scm_prin1 and then passed around to all printing functions as an
7079 argument. A cache `print_state_pool' enables reuse of print
7081 (scm_make_print_state): New function.
7082 (scm_iprin1): Adaption to print states.
7083 (scm_iprlist): An initial "hare and tortoise" scan brings down
7084 time complexity to O (depth * N). (Better time complexity will be
7085 achieved when the printing code is completely rewritten.)
7087 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7089 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
7090 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
7091 it gets done whether or not the cache variable has a value.
7093 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7095 Distinguish #f and ().
7096 * __scm.h: #undef SICP.
7097 * pairs.h (SCM_EOL): Delete this definition, equating it with
7099 * tags.h (SCM_EOL): Give it a new definition here; I think I found
7100 the value it used to have. Doc fixes, too.
7102 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
7104 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
7105 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
7106 Lord's implementation of structs, allowing for tail arrays as
7107 described in the manual. Also fixed some bugs. (Both the interface
7108 and the implementation should be improved.)
7110 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
7112 * print.c, print.h: Closures now print like #<procedure foo (x)>.
7113 People who whish to see the source can do `(print-enable 'source)'.
7114 Removed #ifdef DEBUG_EXTENSIONS.
7116 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7118 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
7119 integer (assuming for now accepting an integer is a good thing).
7121 * error.c, fports.c: replace use of %S in lgh_error args with %s.
7122 %S will be used instead for write'ing arguments.
7124 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
7125 asserts. fix a few other asserts.
7126 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
7127 scm_uniform_vector_ref, scm_array_set_x,
7128 scm_dimensions_to_unform_array): change args in
7129 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
7130 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
7131 scm_substring_fill_x): likewise.
7132 gsubr.c (scm_gsubr_apply): likewise.
7133 eval.c (SCM_APPLY): likewise.
7135 * eval.c (4 places): replace scm_everr with lgh_error or
7138 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
7139 scm_memory_error): new procedures.
7140 scm_everr: deleted. can use scm_wta, dropping first two args.
7141 scm_error: convert NULL subr to SCM_BOOL_F.
7143 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
7146 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
7149 * error.c, error.h: new error keys: scm_arg_type_key,
7150 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
7152 scm_wta: reimplement using lgh_error instead of scm_everr.
7154 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
7156 * gdbint.c: scm_lread now has one more argument.
7158 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
7159 scm_port_\1; Added mutator scm_set_port_filename_x (used when
7160 loading source from non-file ports, which, e. g., happens when
7161 using the Emacs interface).
7163 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
7166 * read.c: Added code for recording of positions of source code
7167 expressions; New functions: recsexpr, scm_lreadrecparen;
7168 _scm_make_srcprops --> scm_make_srcprops
7169 (scm_flush_ws): Removed updating of positions counters. This work
7170 is already done by scm_gen_getc
7172 * read.h: Added prototype for scm_lreadrecparen
7174 * print.c: Added #include "alist.h"
7176 * eval.c: Added #include "hash.h"
7178 * eq.c: Added #include "ramap.h"
7180 * options.c: Documentation fixes.
7182 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
7183 (scm_init_srcprop): Adjusted size of initial source-whash. Name
7184 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
7185 --> scm_make_srcprops
7187 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
7188 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
7189 function calls in the definition of the whash access macros.
7191 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
7193 * init.c (scm_boot_guile): Add level of indirection to
7194 scm_boot_guile_1() to ensure that stack base pointer is properly
7195 initialized. There was no guarantee that variable i was the
7196 highest/lowest variable on stack (i.e. the call frame of
7197 scm_boot_guile was not completely protected from gc).
7199 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
7201 * ports.h (scm_port_table): put back file_name, it will be used to
7202 support debugging. Undo related changes in fports.c, ioext.c,
7205 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7207 * ports.h (scm_port_table): remove file_name member for now, it seems
7209 * fports.c (scm_open_file): don't set file_name in PTAB.
7210 (prinfport): don't use file_name in PTAB.
7211 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
7212 * ports.c (scm_add_to_port_table): don't intialize file_name.
7213 (scm_port_file_name): remove for now.
7214 * gc.c (scm_gc_mark): don't mark PTAB file_name.
7216 * fports.h (scm_mkfile): prototype deleted.
7217 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
7219 * debug.c, unif.c: use scm_out_of_range instead of
7220 wta for range errors (ASSERT still needs work).
7222 * error.c, error.h (scm_out_of_range): new procedure.
7224 * error.c, error.h (scm_out_of_range_key): new key.
7226 * posix.c (scm_sync): #else was missing.
7228 * error.c, error.h: append _key to names scm_num_overflow and
7231 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
7232 of consing an empty list.
7233 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
7234 of macros, saves code and string space.
7235 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
7236 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
7237 lower case. Rename scm_syserror_m to scm_syserror_msg.
7238 error.h: prototypes for new procedures.
7240 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
7242 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
7244 * error.c, error.h: setup scm_num_overflow key.
7246 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
7247 Remove definition of SCM_OVSCM_FLOW.
7249 * fports.c (scm_open_file): use SCM_SYSERROR_M.
7251 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
7252 explicit message and args.
7254 * error.c, error.h, __scm.h: change system_error_sym to
7257 * error.c (system_error_sym): remove leading %% from the Scheme name
7260 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
7262 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7264 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
7265 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
7266 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
7267 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
7268 renamed. (These were introduced by unsupervised name
7271 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7273 * print.c: Added code for detection of circular references during
7274 printing. (init_ref_stack, grow_ref_stack): New functions. Added
7275 a hook for printing of closures (accessible via print options).
7276 This leads to a split of calls to scm_iprin1 into two classes:
7277 elementary print operations (e. g. the code which prints a smob)
7278 still use scm_iprin1 while top level calls (like scm_display) use
7279 scm_prin1. scm_prin1 begins by clearing the data structure used
7280 to record reference information.
7282 * print.h: Added declarations of scm_prin1 and scm_prlist.
7284 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
7286 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
7288 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
7290 * error.c (err_head): scm_iprin1 --> scm_prin1
7292 * debug.c: Adjusted header comment.
7296 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7298 * strerror.c: Doc fix.
7300 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7302 * gdbint.c (gdb_read): Now possible to run during GC.
7303 (unmark_port, remark_port): New functions.
7305 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
7307 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
7308 of allocating a new string object. Also, increase size by
7309 the factor 2 instead of 1.5.
7311 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
7313 * __scm.h (SCM_P): Corrected to run under traditional C.
7315 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
7318 * async.c: Calls to scm_sysintern corrected.
7320 * async.h (scm_async_clock): Redundant declaration removed.
7322 * continuations.c (scm_dynthrow): Redundant declaration removed.
7324 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
7325 Definition typos corrected.
7327 * debug.h: Missing declarations of functions in debug.c added
7330 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
7331 Missing declarations to functions in eval.c added.
7333 * filesys.c: Possibly uninitialized variable rv.
7335 * gc.h (scm_object_addr, scm_unhash_name): Missing
7336 declarations of functions defined in gc.c added.
7338 * genio.c: Possible typos str_data -> wstr_data. ???
7340 * genio.c: Possibly unintended shadowing of local variable
7341 `int c' (gotos out of scope of inner `c'). ???
7343 * init.c: Uninitialized `SCM last' may be used.
7345 * ioext.h: (scm_sys_isatty_p): Typo.
7347 * list.h (scm_list_head): Missing prototype for function in
7350 * numbers.c (scm_two_doubles): Changed from extern to static
7351 (is used only within numbers.c).
7353 * numbers.h: Repeated declarations removed.
7355 * ports.h (scm_close_all_ports_except): Declaration for the
7356 function defined in ports.c added.
7358 * posix.h: Missing declarations added.
7360 * procs.h (scm_make_subr_opt): Missing declaration added.
7362 * socket.h (scm_sys_gethost): Missing declaration added.
7364 * socket.h: Redundant declarations removed (they are in fdsocket.h).
7366 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
7367 Missing declarations added.
7369 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
7371 * struct.c: Uninitialized variable `SCM answer' may be used.
7373 * unif.c (l2ra): Declaration prototype.
7375 * unif.c (scm_array_equal_p): Dummy definition removed (it is
7376 defined in ramap.c).
7378 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
7379 Redundant declarations removed (they are in ramap.h).
7381 * variable.h (scm_make_udvariable,
7382 scm_make_undefined_variable): Declaration corrected to
7383 correspond variable.c.
7385 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
7386 Missing declarations added.
7388 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
7390 * Makefile.in (distclean): Don't forget to delete fd.h.
7392 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7394 * fd.h.in, tags.h: Trivial cleanups.
7396 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
7397 marksweep.h just declared functions from gc.c.
7398 * gc.h, libguile.h: Don't #include "marksweep.h".
7399 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7400 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
7401 dependencies updated.
7403 * libguile.h: Don't #include "files.h"; it's been deleted.
7405 * files.c (scm_sys_delete_file): Moved to filesys.c.
7406 File is now empty; deleted.
7408 * filesys.c: scm_sys_delete_file is now here. Remove
7409 #if's; they seem to rely on remnants of an old portability
7410 regimen. If the problems come up again, solve them properly,
7411 using autoconf. Specifically: Don't test M_SYSV, and #define
7412 remove to be unlink if it's #defined; don't use remove just
7413 because HAVE_STDC_HEADERS is #defined.
7414 * filesys.h: Add declarations for scm_sys_delete_file.
7415 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7416 files.o, files.h, files.c, and files.x.
7417 * init.c: Don't #include "files.h", and don't call scm_init_files.
7419 Use SCM_P instead of PROTO; the latter intrudes on the user's
7421 * params.h: Deleted; definition of SCM_P moved to...
7422 * __scm.h: ... here, where it replaces PROTO macro.
7423 * libguile.h, smob.h: Don't #include "params.h".
7424 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
7425 smob.h: Fix prototypes accordingly.
7426 * Makefile.in: Update dependencies.
7427 (inner_h_files): Remove params.h.
7429 * gc.c: #include "gc.h"; every module should include its header,
7430 to let the compiler cross-check the declarations against the
7433 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
7434 simpos.h: #include "libguile/__scm.h".
7436 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
7438 * init.c: Don't forget to #include smob.h and init.h.
7439 * Makefile.in: Dependencies updated.
7441 * smob.h: Use PROTO instead of #if __STDC__.
7443 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
7445 * __scm.h: Doc fixes.
7447 * __scm.h, libguile.h: Use "quotes" in the #includes, not
7448 <angles>; this allows `make depends' to work properly.
7450 * libguile.h: #include smob.h and pairs.h before the others; they
7451 define typedefs used by other headers.
7453 C files should #include only the header files they need, not
7454 libguile.h (which #includes all the header files); the pointless
7455 recompilation was wasting my time.
7456 * Makefile.in (all .o dependency lists): Regenerated.
7457 * libguile.h: Don't try to get a definition for size_t here...
7458 * __scm.h: Do it here.
7459 * _scm.h: Since this is the internal libguile header, put things
7460 here that all (or a majority) of the libguile files will want.
7461 Don't #include <libguile.h> here; that generates dependencies on
7462 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
7463 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
7464 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

7561 * weaks.c: Get "weaks.h".
7563 * stackchk.h: #include "libguile/debug.h",
7565 * print.h, read.h: #include "options.h", since everyone who uses
7566 either of these files will need that.
7568 * smob.h: #include "ports.h", "genio.h", and "print.h", since
7569 anyone who uses this file will need them to define the smob
7570 printing functions. Also, get markers.h, since people will need
7571 to #define the mark functions.
7573 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
7574 * ports.h: ... to here.
7576 * ports.h (scm_port_table_size): Explicitly give type as 'int';
7577 don't rely on archaic C default type rules.
7579 * fports.h: #include "libguile/ports.h", since you need that in
7580 order to parse this.
7582 * genio.h: #include "libguile/print.h", because you need that to
7583 parse this; don't bother #including "ports.h", since print.h gets
7586 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
7588 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
7589 this; it's now a reference to an element of *scm_root.
7591 * debug.h: Don't #include "options.h"; the compiler won't be able
7592 to find that once the headers are installed; instead, #include
7593 "libguile/options.h".
7594 * gc.h: Same, with marksweep.h.
7595 * mbstrings.h: Same, with symbols.h.
7596 * scmhob.h: Same, with _scm.h.
7597 * smob.h: Same, with params.h.
7599 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
7600 C files; there's no need for this, and it forces recompilations
7603 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
7605 * error.c (scm_error): declare scm_error_callback.
7607 * error.h: prototype for scm_error_callback.
7609 * __scm.h: define lgh_error.
7610 (SCM_SYSERROR): redefine using lgh_error.
7612 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
7614 * error.c (scm_error): new procedure.
7616 * error.h: prototype for scm_error.
7618 * Makefile.in (install): install scmconfig.h from the current
7619 directory, not $(srcdir).
7621 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7623 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
7624 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
7625 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,

7631 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
7632 vports.h, weaks.h: #include "libguile/__scm.h", not
7633 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
7634 dependencies are within libguile properly.
7636 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7638 * Makefile.in (.c.x): Simplify; there's no need to run this rule
7639 when scmconfig.h doesn't exist.
7641 * load.c (scm_sys_try_load): Correct spelling.
7643 * feature.c (scm_loc_features): Make this static.
7645 * Makefile.in (libpath.h): Omit trailing slash from path. We
7646 shouldn't require it of users, so why put it here?
7648 Move code to initialize and search %load-path from ice-9 to C
7649 code, so we can use the load-path to find the ice-9 boot code;
7650 this makes it easier to run Guile without installing it. See
7651 corresponding changes in guile/Makefile.in.
7652 * feature.c: Move stuff concerned with the load path to load.c.
7653 (scm_compiled_library_path): Deleted.
7654 Don't #include libpath.h here.
7655 * feature.h: Don't mention scm_compiled_library_path.
7656 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
7657 <sys/stat.h>, and <unistd.h> (if present).
7658 (R_OK): #define if the system hasn't deigned to.
7659 (scm_loc_load_path): New variable.
7660 (scm_init_load_path, scm_sys_search_load_path,
7661 scm_sys_try_load_path): New functions.
7662 (scm_init_load): Initialize scm_loc_load_path to point to the
7663 value cell of the Scheme %load-path variable.
7664 * load.h: Add declarations for scm_sys_search_load_path,
7665 scm_sys_try_load_path.
7666 * init.c: Call scm_init_load_path.
7667 * Makefile.in (feature.o, load.o): Dependencies updated.
7669 * load.c, load.h: Rewrite using PROTO macro.
7671 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7673 * gc.c (scm_cellp): New function: C predicate to determine if an
7674 SCM value can be regarded as a pointer to a cell on the heap.
7676 * gc.h: Added declaration of scm_cellp.
7678 * gdb_interface.h: New file: The GDB interface header from the GDB
7681 * gdbint.c: New file: GDB interface.
7683 * gdbint.h: New file: GDB interface.
7685 * libguile.h: Added #include <libguile/gdbint.h>.
7687 * init.c (scm_boot_guile): Added scm_init_gdbint.
7689 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
7690 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
7691 found if object files and source are kept separate).
7693 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
7695 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
7697 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
7699 * configure.in: Don't substitute the values of TCL_SRC_DIR and
7700 TK_SRC_DIR; they're not relevant any more.
7702 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
7703 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
7705 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
7707 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
7708 search path, so we can find the <libguile/MUMBLE.h> headers.
7710 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
7712 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
7713 implicit in the .c.o rule.
7714 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
7717 Put the library path in a header file, instead of passing it on
7718 the command line in every compilation.
7719 * Makefile.in (libpath.h): New target.
7720 (feature.o): Depend on libpath.h.
7721 (clean): Delete libpath.h.
7722 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
7723 * feature.c: ... #include "libpath.h" here.
7724 * .cvsignore: Ignore libpath.h.
7726 Don't install the unwashed masses of Guile header files in the
7727 main #include path; put most of them in a subdirectory called
7728 'libguile'. This avoids naming conflicts between Guile header
7729 files and system header files (of which there were a few).
7730 * Makefile.in (pkgincludedir): Deleted.
7731 (innerincludedir): New variable; this and $(includedir) are enough.
7732 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
7733 (installed_h_files): Divide this up. Now this variable lists
7734 those header files which should go into $(includedir) (i.e. appear
7735 directly in the #include path), and ...
7736 (inner_h_files): ... this new variable says which files appear in
7737 a subdirectory, and are referred to as <libguile/mumble.h>.
7738 (h_files): List them both.
7739 (install): Create innerincludedir, not pkgincludedir. Put
7740 the installed_h_files and inner_h_files in their proper places.
7741 (uninstall): Corresponding changes.
7742 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
7743 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
7744 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,

7750 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
7751 vports.h, weaks.h: Find __scm.h in its new location.
7752 * __scm.h: Find scmconfig.h and tags.h in their new locations
7753 (they're both "inner" files).
7755 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
7757 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
7759 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
7761 * posix.c: Doc fixes.
7763 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
7765 * socket.c: Don't include a prototype for inet_aton; just use a
7766 K&R style declaration, to avoid warnings but minimize the chance
7767 of conflicts with the system.
7769 On NextStep, <utime.h> doesn't define struct utime, unless we
7770 #define _POSIX_SOURCE before #including it.
7771 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
7772 * acconfig.h: New comment text for above CPP symbol.
7773 * configure.in: Call it.
7774 * posix.c: #define _POSIX_SOURCE if it seems necessary.
7776 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
7778 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
7779 testing for __EMX__.
7781 * posix.c: #include <libc.h>, if it exists.
7783 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
7784 don't even know if the latter exists.
7786 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
7787 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
7788 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
7790 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
7792 (scm_init_posix): Use them when initializing the Scheme constants
7795 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
7797 * Makefile.in (libdir, includedir, bindir): Use the
7798 autoconf-supplied values, instead of deriving them ourselves.
7799 (pkgincludedir, datadir, pkgdatadir): New variables.
7800 (install, uninstall): Put the header files in a special
7801 subdirectory, not in the main search path.
7803 * Makefile.in (ALL_CFLAGS): Provide the proper value for
7804 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
7806 * Makefile.in (IMPLPATH): Deleted; never used.
7808 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
7809 on the Tcl/Tk source any more.
7810 (INCLUDE_CFLAGS): Remove references to the above.
7812 * Makefile.in (version.o): Corrected dependencies.
7814 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
7816 * libguile.h: #include "version.h"
7818 * init.c (scm_boot_guile): Call scm_init_version.
7819 * gscm.c (gscm_run_scm): Call scm_init_version.
7821 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
7822 GUILE_VERSION): AC_DEFINE these.
7823 (acconfig.h): #undef the above symbols.
7825 * Makefile.in (libobjs): Add version.o.
7826 (installed_h_files): Add version.h.
7827 (c_files): Add version.c.
7828 (gen_c_files): Add version.x.
7829 (version.o): New rule.
7830 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
7831 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

7839 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
7840 weaks.o): Add version.h to dependency lists.
7841 (markers.o): Remove duplicate rule.
7843 * version.h: New file.
7845 * version.c: New file.
7847 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7849 * symbols.c (scm_strhash): scm_downcase is now a function, not an
7850 array; use it appropriately. Since GCC is quite happy to
7851 subscript functions, it never warned us about this; we should use
7852 -Wpointer-arith in the future. I guess we never tested
7855 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
7857 * socket.c: Doc and copyright fixes.
7859 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7861 * debug.c: Fixed and improved gdb support.
7863 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7865 * socket.c: Added declaration of inet_aton to avoid compiler
7866 warning. (Hope this solution is correct.)
7868 * stime.c: Added declaration of ftime. (This is missing in
7871 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
7873 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
7875 * Makefile.in (c_files): add strerror.c.
7877 * strerror.c: new file from Emacs' sysdep.c.
7878 maybe configure should also check for sys_errlist.
7880 * configure.in (AC_REPLACE_FUNCS): add strerror.
7882 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7884 * debug.c (scm_init_debug): Added initialization for
7885 scm_evaluator_traps.
7887 * debug.h, debug.c: Various name changes.
7888 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
7889 "debug-options-interface". See commentary in options.c.
7891 * options.h, options.c: Options now have documentation strings.
7892 Also added a long explanatory commentary.
7894 * eval.c, print.h, print.c, read.h, read.c: Modifications to
7897 * gscm.c, init.c, root.c, throw.c: Bug fixes:
7898 last_debug_info_frame is now updated in all cases.
7900 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
7903 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7905 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
7906 Added option STACK_CHECKING.
7908 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7910 * Makefile.in: Added {debug,options,srcprop}.{h,c}
7912 * __scm.h: Removed symbols for debugging support.
7914 * acconfig.h: Added symbols for debugging support.
7916 * configure.in: Added user option for debugging support.
7917 --enable-debug will include the debugging code into libguile.a.
7919 * continuations.c (scm_make_cont): Enlarged the #if 0 around
7920 scm_relocate_chunk_to_heap.
7922 * debug.c: New file: low-level debugging support. It also
7923 includes support for debugging with gdb. (The extensions to gdb
7924 are written by Per Bothner at Cygnus.)
7926 * debug.h: New file: low-level debugging support.
7928 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
7929 argument pairs. Extensive modifications to the debugging
7930 evaluator. Added "SECTION:" commentaries to clarify what happens
7931 when, during double compilation. Renamed EVALIMP --> EVALIM.
7932 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
7933 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
7934 the beginning of the file. New procedure: scm_unmemocopy.
7935 Added some global state variables needed by the debugging
7936 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
7937 check_entry, check_apply, check_exit, debug_options and
7938 evaluator_traps. New acro: undefine.
7940 * eval.h: Renamed EVAL --> XEVAL.
7942 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
7943 --> scm_make_weak_key_hash_table.
7945 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
7946 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
7948 * libguile.h: Conditionally include debug.h
7950 * objprop.c (scm_object_properties, scm_set_object_properties_x):
7951 scm_object_properties shouldn't return handle. `handle' now gets
7952 initialized in scm_set_object_properties_x. scm_object_properties
7953 doesn't any longer create an entry in scm_object_whash.
7955 * options.c: New file: handling of run time options.
7957 * options.h: New file: handling of run time options.
7959 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
7961 * print.c: New procedure: scm_print_options
7963 * print.h: Defines for print options.
7965 * read.c: New procedure: scm_read_options
7967 * read.h: Defines for reader options.
7969 * root.h: Added scm_source_whash among scm_sys_protects.
7971 * srcprop.c: New file: source properties.
7973 * srcprop.h: New file: source properties.
7975 * throw.c (jbsmob): Jump buffers are now correctly allocated.
7976 (Bug found by A. Green.)
7978 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
7980 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
7982 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
7984 * libguile.h: #include "objprop.h"; I guess this was forgotten.
7986 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
7987 and should be called by the final client.
7989 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
7991 * gc.h: Use the PROTO macro when declaring functions.
7992 * gc.c: Use the PROTO macro when declaring static functions.
7993 Remove the CPP hair around function definitions.
7995 * gc.c (scm_init_storage): Initialize scm_asyncs.
7997 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
7998 preprocessor symbol; "__scm.h" is where it might get #defined.
7999 * __scm.h: Similar: #include <scmconfig.h> before testing
8002 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
8004 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
8006 * init.c (scm_boot_guile): Add init_func argument; call
8007 (*init_func) instead of calling scm_appinit; it's ucky to
8008 hard-code names for the user's procedures.
8009 * init.h (scm_boot_guile): Adjust declaration.
8011 * __scm.h (PROTO): New macro, for declaring functions with
8014 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
8015 eliminate all the __STDC__ conditionals.
8016 (scm_boot_guile): Add declaration.
8017 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
8018 Remove __STDC__ conditionals around function definitions; the
8019 declarations in init.h will provide the same information, more
8022 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
8023 complain about it in the error message; the error message is
8024 adequate without that note, and there's nothing the user can do
8027 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
8029 * Makefile.in (ancillary): Drop def.sed.
8031 * posix.c (scm_init_posix): Use numeric values, rather than
8032 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
8033 F_OK. The symbols aren't available on some systems, and I'm
8034 pretty sure their values are fixed by common widespread practice.
8035 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
8037 More functions unavailable on some systems.
8038 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
8039 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
8041 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8042 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
8043 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
8044 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
8045 stub that signals an error as the #else.
8047 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
8049 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
8051 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
8053 * unif.c: include ramap.h.
8055 * read.c (endif): case_insensative_p renamed case_insensitive_p.
8057 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
8059 * ports.c: include sys/ioctl.h.
8061 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
8063 * configure.in: check for sys/ioctl.h.
8065 * ports.c: include <malloc.h> not "malloc.h".
8067 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8069 * fports.c: remove ttyname and tmpnam declarations.
8071 * posix.c: fewer ttyname declarations.
8073 * fports.c: include <string.h> not "string.h".
8075 * init.c, ioext.c: include string.h and unistd.h.
8077 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8079 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
8080 genio.c, simpos.c, vports.c: include string.h.
8082 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
8084 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
8086 (scm_addr_buffer_size): change type from scm_sizet to int.
8087 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
8088 from scm_sizet to int.
8090 * error.c: include unistd.h.
8092 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
8095 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
8097 * __scm.hd, def.sed: deleted.
8099 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
8101 Changes for NeXT, suggested by Robert Brown.
8102 * configure.in: Call AC_TYPE_MODE_T.
8103 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
8104 NeXT. Put header file list in alphabetical order.
8105 * configure, scmconfig.h.in: Regenerated.
8106 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
8108 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
8111 * acconfig.h: New file, providing documentation for the CPP
8112 symbols defined in configure.in
8113 * acconfig-1.5.h: Removed; superceded by the above.
8115 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
8117 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
8119 * fports.c (scm_open_file): don't return #f, throw error.
8121 * ioext.c (fileno): renamed from %fileno.
8122 (soft-fileno): deleted.
8124 * ports.c (scm_port_revealed): don't need to check for -1 from
8126 (scm_set_port_revealed_x): return unspecified, not #f.
8128 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
8130 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
8132 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
8134 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
8136 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8138 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
8139 This is necessary on Ultrix, and doesn't hurt portability.
8141 * Makefile.in (dist-dir): New target, implementing a new dist system.
8142 (installed_h_files): Put in alphabetical order.
8143 Remove duplicate entries for markers.h and unif.h.
8144 (c_files): Remove duplicate entries for markers.c.
8145 (ancillary): Renamed from anillery; all uses changed. Remove
8146 PLUGIN; it's a directory, and needs special treatment in dist-dir.
8147 Remove all the ../doc/* files; doc/Makefile.in handles that.
8149 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
8151 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
8152 every if must have an else, or else the whole command has a
8153 non-zero exit code whenever the if's condition is false.
8155 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
8157 * posix.c: include string.h.
8159 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
8161 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
8164 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
8165 Remove leading % from scheme names.
8166 Do not return error values, call SCM_SYSERROR or similar.
8168 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
8170 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
8172 * struct.c (scm_init_struct): new file.
8174 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
8176 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
8177 (scm_list_head): added list-head for rapidly chopping argument
8178 lists off of longer lists (and similar).
8180 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
8182 * objprop.c (scm_object_property): assq the cdr of the whash
8183 handle for obj, not the handle itself.
8185 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
8187 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
8188 weak hash tables last of all marking to avoid an obscure gc bug.
8189 WARNING: circular lists stored in a weak hash table will hose us.
8191 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
8193 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
8194 new functions similar to scm_substring_move_left_x and
8195 scm_substring_move_right_x.
8197 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
8199 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
8202 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
8204 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
8206 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
8208 * strports.c (scm_strprint_obj): convenience function. C for
8209 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
8211 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
8212 removed to a separate library
8214 * init.c (scm_boot_guile): copied from guile-tcl.c.
8215 Initialization specific to tcl interpreters removed.
8217 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
8219 * ports.c (scm_ports_prehistory): size malloced here doesn't
8220 matter so long as it is non-0 (got rid of "* 4").
8222 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
8224 * gscm.h: gscm_mkarray eliminated (presumably was not being used
8225 since its definition was bogus).
8227 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
8229 * mallocs.[ch]: back again (for rx at least).
8231 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
8233 * ports.c: removed functions relating to the mapping between ports
8234 and descriptors. (That stuff is unix-specific and should be collected
8235 in a separate library).
8237 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
8238 (Tom Mckay@avanticorp.com)
8240 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
8242 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
8243 handled correctly (SCM_FREEP was applied to them) -- test for
8244 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
8245 being overwritten with #f. (brown@grettir.bibliotech.com)
8247 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
8249 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs
8250 for a specific symbol or for all symbols.
8252 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
8254 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak

8412 initialization to fix a race condition.
8414 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
