1 2000-07-31 Gary Houston <ghouston@arglist.com>
3 * net_db.c: declare h_errno only if HAVE_H_ERRNO is not defined
4 (thanks to Richard Kim for the bug report).
6 2000-07-30 Marius Vollmer <mvo@zagadka.ping.de>
8 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
9 scm_assoc_remove_x): Use scm_delq1_x instead of scm_delq_x, since
10 using the latter is pointless.
12 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
14 * gc.c (scm_gc_sweep): Renamed local variable from 'free' to
15 'free_struct_data' to avoid confusion with stdlib's 'free'.
17 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
19 * vectors.c (scm_make_vector): Fix the initialization order of
20 the vector such that the type cell is initialized last.
22 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
24 * struct.[ch] (scm_struct_init): Made static. Fixed not to rely
25 on the struct cell to be fully initialized.
27 * struct.c (scm_make_struct, scm_make_vtable_vtable): Fix the
28 initialization order of the struct such that the type cell is
31 2000-07-25 Marius Vollmer <mvo@zagadka.ping.de>
33 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
34 scm_assoc_remove_x): Remove only the first cell with a matching
37 2000-07-24 Marius Vollmer <mvo@zagadka.ping.de>
39 * stime.c (scm_strftime): Recognize a return value of zero from
40 strftime as buffer overflow and take care to detect a valid zero
41 length result regardless. Thanks to David Barts!
43 2000-07-23 Marius Vollmer <mvo@zagadka.ping.de>
45 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
46 scm_assoc_remove_x): Remove all cells whose key is eq, eqv, or
47 equal (respectively) to the argument key, not all cells that are
48 eq, eqv, or equal to the first cell with the argument key. Thanks
51 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
53 * gc.h (SCM_FREE_CELL_CDR, SCM_SET_FREE_CELL_CDR), hooks.c
54 (make_hook), modules.c (OBARRAY, USES, BINDER): Pack and unpack
55 SCM values appropriately.
57 * modules.c (scm_standard_eval_closure): Don't pass an inum to
58 scm_makcclo, but rather a long value.
60 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
62 read.c (scm_lreadrecparen), srcprop.c (scm_set_source_property_x):
63 SCM_SETCDR and SCM_WHASHSET macros don't deliver a return value.
64 Thanks to Han-Wen Nienhuys for the bug report.
66 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
68 * root.[ch] (scm_call_catching_errors): Deprecated.
70 * root.c (scm_init_root): Initialize the root smob type using the
71 standard initialization functions.
73 2000-07-17 Marius Vollmer <mvo@zagadka.ping.de>
75 * eval.c (unmemocopy): Don't rely on V being a list of at least
76 one element. Thanks to Bill Schottstaedt!
78 2000-07-15 Michael Livshin <mlivshin@bigfoot.com>
80 * gc.c (scm_done_free): new.
81 expanded comments about scm_done_malloc.
83 * gc.h: added prototype for scm_done_free
85 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
87 * gc.h (scm_take_stdin): Removed.
89 * gc.h (SCM_VALIDATE_CELL): Delegate cell checks to function
90 scm_assert_cell_valid to allow extensions to the checking
91 functionality without need to recompile everything.
93 * gc.[ch] (scm_assert_cell_valid, scm_set_debug_cell_accesses_x):
94 Added as conditionally compiled functions for the case that
95 SCM_DEBUG_CELL_ACCESSES is enabled.
97 * gc.c (debug_cells_p): Added to indicate whether compile-time
98 included cell access debugging is run-time enabled.
100 * gc.[ch] (scm_gc_running_p): Added to indicate that scm_igc is
101 being executed. Intended to be used instead of scm_gc_heap_lock
104 * error.c (scm_error), gdbint.c (SCM_GC_P): Use scm_gc_running_p
105 instead of scm_gc_heap_lock.
107 * gc.c (scm_igc): Set scm_gc_running_p to true while running.
109 * gc.c (scm_mark_locations): Don't mark free cells.
111 * weaks.c (scm_scan_weak_vectors): Use SCM_FREE_CELL_P instead of
114 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
116 * gc.c (scm_mark_locations): Minimized some variable scopes and
117 simplified the code a bit.
119 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
121 * gc.h (SCM_SET_FREE_CELL_TYPE, SCM_SET_FREE_CELL_CDR,
122 SCM_FREE_CELL_P, SCM_FREE_CELL_CDR): Added since free cells
123 should not be accessed via SCM_C[AD]R. Further, using dedicated
124 macros to access free cells allows all other cell accessing macros
125 to treat acesses to free cells as errors, thus enabling better
126 error checks for cell accesses. SCM_FREE_CELL_P is supposed to
127 replace SCM_FREEP some time.
129 * gc.h (SCM_NEWCELL, SCM_NEWCELL2), gc.c (map_free_list,
130 free_list_length, scm_check_freelist, scm_debug_newcell,
131 scm_debug_newcell2, freelist_length, scm_gc_for_newcell,
132 scm_gc_mark, scm_gc_sweep, init_heap_seg): Only use the dedicated
133 cell accessors when accessing free cells.
135 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
137 * gc.h (SCM_CELL_WORD, SCM_CELL_OBJECT): Treat the referenced
138 object as const in order to make the compiler warn about code like
139 SCM_CELL_WORD (x, n) = y. Instead, SCM_SET_CELL_WORD (x, n, y)
142 (SCM_CELL_WORD_LOC, SCM_CARLOC, SCM_CDRLOC): Return the address
143 as an address to a non-const object, since these macros are used
144 to allow direct write access to objects.
146 2000-07-07 Dirk Herrmann <D.Herrmann@tu-bs.de>
148 * hashtab.c (scm_hash_fn_create_handle_x): Signal an error if the
149 given hash table has no slots.
151 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
153 * gc.c (policy_on_error): Added in order to allow alloc_some_heap
154 to react to malloc failures in a context dependent way.
156 (scm_check_freelist): No need to flush streams before abort().
158 (scm_gc_for_newcell): Try to allocate new memory in three phases:
159 grow heap if preferred, if still no memory available collect
160 garbage, if still no memory available grow heap.
162 (heap_segment_table_size): Added to always reflect the actual
163 size of the heap segment table, because scm_n_heap_segs may differ
164 from the heap segment table size.
166 (alloc_some_heap): In case of malloc failure, react according to
167 the new policy_on_error parameter (either return to caller or
168 abort immediately). Further, keep heap_segment_table_size up to
171 (scm_init_storage): Initialize heap_segment_table_size.
173 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
175 * gh.h: Don't include <stdio.h>. Thanks to Han-Wen Nienhuys for
178 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
180 * __scm.h (SCM_OUTOFRANGE, SCM_NALLOC, SCM_HUP_SIGNAL,
181 SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL, SCM_SEGV_SIGNAL,
182 SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL, SCM_SIG_ORD,
183 SCM_ORD_SIG, SCM_NUM_SIGS): Re-introduce these as deprecated
186 * error.c (scm_wta): Re-introduce dispatching for SCM_OUTOFRANGE
187 and SCM_NALLOC, but as a deprecated feature.
189 2000-06-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
191 * debug.c: Added #include fluids.h.
193 * numbers.c (scm_gr_p, scm_leq_p, scm_geq_p): Turned into
194 primitive generics. (Thanks to Nicolas Neuss.)
196 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
198 * gc.c (alloc_some_heap): Use scm_memory_error to indicate a
199 failed attempt to get additional memory from the system.
201 (scm_gc_for_newcell): Changed the control structure to make the
202 behaviour explicit for the case that gc is not able to free any
205 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
207 * __scm.h (SCM_OUTOFRANGE): Removed.
209 * error.c (scm_wta): Removed sick dispatch code for range
210 errors. (More sick dispatches still to be removed.)
212 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
213 scm_hash_fn_remove_x): Eliminate redundant test for if unsigned
214 value is non-negative. Use scm_out_of_range to signal range
217 * hooks.c (make_hook), unif.c (scm_aind): Use scm_out_of_range to
220 * list.c (scm_list_ref, scm_list_set_x, scm_list_cdr_set_x): Fix
221 error reporting (now uses original input parameter to report wrong
222 type argument errors). Use SCM_OUT_OF_RANGE to report range
223 errors and SCM_WRONG_TYPE_ARG to report type errors.
225 * strings.c (scm_substring): Make range checks for negative
226 values explicit (former behaviour relied on an implicit
227 conversion from signed to unsigned). Don't use SCM_ASSERT for
230 * unif.c (scm_aind, scm_transpose_array, scm_bit_set_star_x,
231 scm_bit_count_star): Use scm_out_of_range to signal range
234 * unif.c (scm_transpose_array, scm_bit_position), vectors.c
235 (scm_vector_ref, scm_vector_set_x, scm_vector_move_left_x,
236 scm_vector_move_right_x): Use SCM_ASSERT_RANGE to check ranges.
238 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
240 * validate.h (SCM_VALIDATE_INUM_MIN_COPY,
241 SCM_VALIDATE_INUM_MIN_DEF_COPY, SCM_VALIDATE_INUM_RANGE_COPY):
242 Perform all range checks based on the input value. The former way
243 of using the value that is assigned to the target variable fails
244 if the assignment to the target variable itself can change the
245 value because of type conversion.
247 (SCM_ASSERT_RANGE): Use scm_out_of_range to signal range errors.
249 2000-06-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
251 * gc.c (scm_gc_for_newcell): Behave gracefully also if scm_igc
252 doesn't yield any new cells. In theory this could happen if all
253 cells allocated with NEWCELL are either in use or conservatively
254 marked and all cluster spine cells are conservatively marked.
257 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
259 * __scm.h (SCM_NALLOC): Removed.
261 * error.c (scm_wta): Removed sick dispatch code for memory
262 errors. (More sick dispatches still to be removed.)
264 * numbers.c (scm_mkbig, scm_adjbig), ports.c (scm_make_port_type),
265 random.c (scm_i_copy_rstate, scm_c_make_rstate), smob.c
266 (scm_make_smob_type), srcprop.c (scm_make_srcprops), vectors.c
267 (scm_vector_set_length_x): Now using scm_memory_error to signal
270 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
272 * __scm.h: Removed some commented code and fixed some comments.
274 (SCM_HUP_SIGNAL, SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL,
275 SCM_SEGV_SIGNAL, SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL,
276 SCM_SIG_ORD, SCM_ORD_SIG, SCM_NUM_SIGS): Removed.
278 * async.c: Removed some commented code.
280 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
282 * gc.c (scm_gc_mark, scm_gc_sweep, scm_must_malloc,
283 scm_must_realloc, scm_must_free, alloc_some_heap): Use the
284 appropriate error signalling function.
286 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
288 * root.h (scm_first_type): Removed.
290 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
292 * gc.c (MIN_GC_YIELD): Removed.
294 2000-06-28 Michael Livshin <mlivshin@bigfoot.com>
296 * gc.c (scm_gc_for_newcell): don't try to do GC if it's blocked,
299 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
301 * async.c (scm_gc_async, scm_gc_vcell, scm_sys_gc_async_thunk):
304 (scm_init_async): Moved initialization for scm_gc_async and
305 scm_gc_vcell to gc.c. Moved initialization of scm_asyncs here
308 * async.h (scm_gc_async): Not globally visible any more.
310 * gc.c (scm_gc_stats): Made callable even from within regions
313 (scm_gc_end): Eliminate the hardcoding of the marking of the
314 scm_gc_async from the gc core.
316 (scm_init_storage): Don't initialize the scm_asyncs list here.
317 This is now done in asyncs.c.
319 (scm_gc_vcell): Moved here from async.c.
321 (gc_async): Renamed from scm_gc_async, moved here from async.c
324 (gc_async_thunk): Renamed from scm_sys_gc_async_thunk and moved
327 (mark_gc_async): New hook function for scm_after_gc_c_hook.
329 (scm_init_gc): Added initialization of scm_gc_vcell and
330 gc_async. Further, add mark_gc_async to scm_after_gc_c_hook.
332 * init.c (scm_boot_guile_1): scm_init_gc requires asyncs to be
335 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
337 * gc.c (scm_igc): Removed commented code that once was intended
338 to unprotect struct types with no instances.
340 * root.h (scm_type_obj_list): Removed.
342 2000-06-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
344 * async.c (scm_init_async): Switch to standard way of smob
347 2000-06-21 Michael Livshin <mlivshin@bigfoot.com>
349 * guile-doc-snarf.in: use cut instead of sed, that's much much
350 faster. also, don't call basename more than needed. and, to gain
351 a couple of microseconds more, don't call cat needlessly. (thanks
354 2000-06-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
356 * guile-snarf.awk.in, guile-snarf.in, snarf.h: Rename SCM__I to
357 SCM_SNARF_INIT_START, SCM__D to SCM_SNARF_DOC_START, SCM__S to
358 SCM_SNARF_DOCSTRING_START and SCM__E to SCM_SNARF_DOCSTRING_END.
360 2000-06-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
362 * eval.c, eval.h (scm_top_level_lookup_closure_var): Added.
363 #include "libguile/fluids.h".
365 * eval.h (SCM_TOP_LEVEL_LOOKUP_CLOSURE): New macro which replaces
366 SCM_CDR (scm_top_level_lookup_closure_var) everywhere.
368 * root.h (scm_top_level_lookup_closure_var,
369 scm_system_transformer): Removed. (It's no sense in having the
370 *variable* be a "fluid".)
372 * root.c (mark_root): Removed marking of
373 s->top_level_lookup_closure_var and s->system_transformer.
375 * modules.c (scm_selected_module): the_module is now a fluid.
377 2000-06-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
379 * gc.h, tags.h: Be kind to compilers which must see hash signs in
380 column 0. (Thanks to Ian Grant.)
382 * numbers.h: Put #ifdef HAVE_LONG_LONGS around declarations using
383 the long_long type. (Thanks to Bernard Urban.)
385 2000-06-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
387 * gc.c, gc.h (scm_default_init_heap_size_1,
388 scm_default_min_yield_1, scm_default_init_heap_size_2,
389 scm_default_min_yield_2, scm_default_max_segment_size): New global
390 variables. Can be customized by the application before booting
391 Guile. (We might want to be able to control these parameters
392 dynamically through the "options interface" in the future, but
393 note that that is additional functionality. Here we're giving
394 default values which the environment variables can override.)
396 * list.c (scm_cons_star): Updated comment.
398 * smob.h: Changed comments for scm_make_smob_type and
399 scm_make_smob_type_mfpe, warning that the latter might be
400 deprecated in a future release.
402 2000-06-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
404 * list.[ch] (scm_cons_star/cons*): Renamed from
407 * list.[ch] (scm_list_star/list*): Provided as a deprecated alias
408 for scm_cons_star/cons*.
410 * gc.c (scm_protect_object): Updated comment.
412 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX): Removed.
414 * tags.h (SCM_UNPACK_CAR, SCM_NDOUBLE_CELLP): Removed.
416 2000-06-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
418 * init.c, init.h (scm_initialized_p): Renamed from `initialized'
421 * gdbint.c (gdb_print): Print warning instead of calling scm_write
422 if Guile isn't yet initialized.
424 * print.c (scm_current_pstate, scm_make_print_state): Simplified
425 tests, using the assumption that Guile has been initialized.
427 Sun Jun 18 14:45:21 2000 Greg J. Badros <gjb@cs.washington.edu>
429 * print.c (s_scm_current_pstate): Do not segfault when the
430 print_state_pool is unitialized in `current-pstate', and better
431 verify its state before altering it in scm_make_print_state().
433 2000-06-18 Michael Livshin <mlivshin@bigfoot.com>
435 * scmsigs.c (s_scm_sigaction): guard the SIGIOT case with an
436 #ifdef -- it's missing on at least one platform. (thanks to
439 2000-06-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
441 * list.c (list*): Added documentation from common-list.scm.
443 2000-06-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
445 * gc.c (scm_unprotect_object): The reference count is guaranteed
446 to be a positive number.
448 2000-06-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
450 * eval.c: Updated comment above scm_map.
452 2000-06-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
454 * gc.c (scm_protect_object): Avoid looking up the object handle
456 (scm_unprotect_object): Abort if scm_unprotect_object is called on
457 an unprotected object.
459 2000-06-14 Michael Livshin <mlivshin@bigfoot.com>
461 * gc.c (scm_unprotect_object): fix a nasty typo bug (thanks to
464 2000-06-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
466 * socket.c (scm_getsockopt): Changed type for `optlen' from int to
468 (scm_accept, scm_getsockname, scm_getpeername, scm_recvfrom):
469 Ditto for `tmp_size'.
470 (scm_addr_buffer_size): Changed type from int to size_t.
472 * random.c: #include <string.h>. (Needed by memcpy.)
474 * guile-snarf.awk.in: Replace the dot_doc_file arg with "-",
475 indicating stdin, instead of "" and don't reset ARGC. This is a
476 workaround for `nawk' in AIX 4.3 on RS6000 but, as far as I know,
477 it is correct, and perhaps even better.
479 2000-06-14 Gary Houston <ghouston@arglist.com>
481 * scmsigs.c (scm_init_scmsigs): if HAVE_SIGINTERRUPT is not
482 defined, add SA_RESTART to the sigaction flags correctly
483 (thanks to Dale P. Smith).
485 2000-06-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
487 * strings.c: #include <string.h>. (Thanks to Bill Schottstaedt.)
489 * net_db.c (scm_resolv_error): Only use macro NETDB_INTERNAL if
490 defined. It isn't on sgi irix 5.3. (Thanks to Bill Schottstaedt.)
492 * Makefile.am (.c.doc): Pipe output (the .x contents) to /dev/null.
494 2000-06-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
496 * fports.c (scm_setvbuf): Use `free' instead of `scm_must_free'
497 since read and write buffers are allocated by `malloc'.
499 * Makefile.am: Removed old test code.
501 * gh_test_c.c, gh_test_repl.c: Removed.
503 2000-06-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
505 * iselect.c (SCM_NLONGBITS): Add workaround for the Sun 4.2
508 * inet_aton.c (inet_aton): Cast init value for `cp'.
510 * ramap.c (s_scm_array_fill_x): Cast `ve' properly in case
513 * symbols.c (scm_intern_obarray_soft,
514 scm_sysintern0_no_module_lookup): Cast `name' to unsigned char ptr
515 in calls to scm_strhash.
517 * strports.c (st_resize_port): Substituted SCM_UCHARS for
519 (st_write): Cast argument to strncpy to char ptr.
520 (scm_mkstrport): Substituted SCM_ROUCHARS for SCM_ROCHARS.
521 (scm_strport_to_string): Cast argument to scm_makfromstr to char
524 * ports.c (scm_ungetc): Cast value to unsigned char ptr before
525 storing in putback_buf.
526 (scm_unread_string): Substituted SCM_ROCHARS for SCM_ROUCHARS.
528 * ioext.c (s_scm_read_line): Cast result of call to
529 scm_do_read_line to unsigned char ptr.
531 * gdbint.c (SEND_STRING): Cast argument to char pointer.
533 * fports.c (fport_flush): Declare `ptr' as unsigned char (was
536 * Makefile.am (DOT_DOC_FILES): List doc-files explicitly. (We
537 shouldn't use Make rules which aren't supported by most Make
539 (OMIT_DEPENDENCIES): Defined to "libguile.h ltdl.h". (We don't
540 want these dependencies recorded, since they would get bogus
541 relative paths; libguile.h is only used in gh.h and guile.c.)
542 (EXTRA_DOT_X_FILES, EXTRA_DOT_DOC_FILES): New variables.
543 (guile-procedures.txt): Depend on EXTRA_DOT_DOC_FILES.
544 (modinclude_HEADERS): Removed kw.h.
546 * guile-snarf.in: Change regexp "^SCM__I" --> "^ *SCM__I".
547 (The preprocessor might insert spaces before the identifier.)
549 * snarf.h (SCM_SNARF_HERE, SCM_SNARF_INIT, SCM_SNARF_DOCS):
550 Renamed from SCM_HERE, SCM_INIT, SCM_DOCS.
552 * smob.h (scm_smobfuns): Removed deprecated type.
554 * smob.c, smob.h (scm_newsmob): Removed deprecated function.
555 (Replaced by `scm_make_smob_type'.)
557 * keywords.c (scm_tc16_kw): Removed deprecated type.
558 (Replaced by scm_tc16_keyword.)
560 * kw.h: Removed deprecated header file.
562 * evalext.c (serial-map): Removed deprected alias for scm_map.
563 (Has been replaced by `map-in-order'.)
565 * ramap.c (serial-array-copy!, serial-array-map!): Removed
566 depracted aliases. (Replaced by `array-copy-in-order!' and
567 `array-map-in-order'.)
569 2000-06-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
571 * gc.h (SCM_VALIDATE_CELL): Rewritten.
572 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
573 SCM_SET_CELL_OBJECT): Use new version of SCM_VALIDATE_CELL.
574 (Thanks to Han-Wen Nienhuys.)
576 2000-06-10 Michael Livshin <mlivshin@bigfoot.com>
578 * guile-doc-snarf.in: don't pipe the CPP output right into sed --
579 write it to the temp file first and check the CPP return code.
580 (I introduced this bug earlier, and this probably caused people
581 with non-GNU C preprocessors to get empty *.x files and not to
582 have the build fail right away...).
584 * scmsigs.c (s_scm_sigaction): guard the SIGSYS case with an ifdef
585 -- at least my libc5-based Linux system doesn't define SIGSYS.
587 2000-06-08 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
589 * snarf.h, guile-snarf.awk.in, guile-snarf.in: Replaced snarf
590 markers with identifiers (SCM__I, SCM__D, SCM__S, SCM__E).
591 (Thanks to Bernard Urban.)
593 2000-06-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
595 * modules.c (scm_system_module_env_p): Fixed detection of system
598 2000-06-06 Marius Vollmer <mvo@zagadka.ping.de>
600 * scmsigs.c (scm_sigaction): Silently ignore setting handlers for
601 `program error signals' because they can't currently be handled by
604 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
606 * procs.h (SCM_SET_SUBRF): Added.
608 * procs.c (scm_make_subr_opt): Don't assign to SCM_SUBRF, use
609 SCM_SET_SUBRF instead. Thanks to Bernard Urban for the bug
612 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
614 * gc.h (SCM_CARLOC, SCM_CDRLOC): Don't take the address of a SCM
617 * sort.c (scm_sorted_p, scm_merge, scm_merge_list_x,
618 scm_merge_list_step): Don't take the address of SCM_CAR. Use
619 SCM_CARLOC instead. Thanks to Bernard Urban for the bug report.
621 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
623 * boolean.h (SCM_TRUE_P): Removed, as people might use it as a
624 replacement for !SCM_FALSEP.
626 * backtrace.c (display_error_body), boolean.h (SCM_BOOLP), gc.c
627 (scm_unhash_name), gh_data.c (gh_module_lookup), load.c
628 (scm_primitive_load), print.c (scm_simple_format), procs.c
629 (scm_procedure_documentation), procs.h (SCM_TOP_LEVEL), ramap.c
630 (scm_array_fill_int), scmsigs.c (scm_sigaction), stacks.c
631 (narrow_stack, scm_make_stack, scm_stack_id), symbols.c
632 (scm_string_to_obarray_symbol), throw.c (scm_catch,
633 scm_lazy_catch, scm_ithrow), unif.c (scm_make_uve, scm_array_p,
634 scm_array_set_x, scm_bit_set_star_x, scm_bit_count_star),
635 validate.h (SCM_VALIDATE_BOOL_COPY, SCM_VALIDATE_PROC): Replace
636 uses of SCM_TRUE_P (x) with SCM_EQ_P (x, SCM_BOOL_T).
638 2000-06-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
640 * eval.c (scm_badformalsp): New static function.
641 (SCM_CEVAL): Check arguments for procedure-with-setter closures.
642 (Thanks to Keisuke Nishida.)
644 The major reason for Guile's slow loading speed has been the fact
645 that a chain of Scheme level procedures has been evaluated for
646 every top-level symbol lookup during the first pass through the
649 The following is a kludge which I suggested four years ago, and
650 which I've repeatedly suggested since. Personally, I've never
651 been bothered by Guile's slow loading speed, so I thought I would
652 let someone else do it...
654 But since the new environments will be included first in
655 Guile-1.5, I thought it would make people happy to get the kludge
658 * modules.c: Added #include "libguile/vectors.h";
659 Added #include "libguile/hashtab.h";
660 Added #include "libguile/struct.h";
661 Added #include "libguile/variable.h";
662 Capture Scheme level `module-make-local-var!' to be used in the
663 standard eval closure.
664 (scm_standard_eval_closure): New primitive.
666 * modules.h (scm_standard_eval_closure): Declare.
668 * eval.c (scm_lookupcar): Test for !SCM_CONSP (SCM_CAR (env))
669 instead of SCM_TRUE (scm_procedurep (SCM_CAR (env))).
671 * symbols.c (scm_sym2vcell): Bypass dispatch in the evaluator for
672 standard eval closures.
674 * variable.c: Code layout fixes.
676 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
678 * Makefile.am: Added LIBS line to libpath which accidentally
679 disappeared in the change of 2000-06-01.
680 (Thanks to Dale P. Smith.)
682 2000-06-03 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
684 * scmsigs.c (scm_segfault): Removed. (Was probably added by
685 mistake since it is not mentioned in ChangeLog.)
687 * gc.h (SCM_VALIDATE_CELL): Cast result to (void) in order to
688 avoid compiler warnings in gcc. (Does this work for other
691 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
693 * gc.h (SCM_VALIDATE_CELL): Don't "use" the value returned by
695 (SCM_CARLOC, SCM_CDRLOC): Define directly instead of using
696 SCM_CELL_OBJECT_0 and SCM_CELL_OBJECT_1. It's not correct to take
697 the address of these expressions since they use SCM_VALIDATE_CELL.
698 (Thanks to Bernard Urban.)
700 * dynl.c: Changed #include <ltdl.h> --> #include
701 "libltdl/ltdl.h". (Thanks to Bill Schottstaedt.)
703 2000-06-01 Craig Brozefsky <craig@red-bean.com>
705 * Makefile.am: libguile_la_LDFLAGS gets -version-info args
706 from GUILE-VERSION definition of LIBGUILE version. Added to
707 libpath.h definitions for guileversion and libguileversion which
708 both get their values from GUILE-VERSION definition.
710 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
712 * numbers.h (SCM_BIGP): Don't use SCM_SMOB_PREDICATE in header
713 file: Code using numbers should not be required to include
716 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
718 * coop-threads.c.cygnus, coop-threads.h.cygnus, fsu-pthreads.h,
719 mit-pthreads.c, mit-pthreads.h: Deleted.
721 * Makefile.am (EXTRA_DIST), scmsigs.c, threads.[ch]: Drop
722 references to deleted files and fsu/mit thread support in
725 2000-05-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
727 * hooks.c (symbol_name, scm_create_hook): Restored the original
728 behaviour of scm_create_hook. Changing it was bad as Carl
729 R. Witty has pointed out.
731 * gc.c (scm_init_gc): We can still rely on scm_create_hook to
734 2000-05-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
736 * gc.c (scm_init_gc): Protect scm_after_gc_hook, since this will
737 soon not be done by scm_create_hook any longer.
739 * hooks.c (make_hook, print_hook, scm_create_hook,
740 scm_make_hook_with_name, scm_make_hook), hooks.h (SCM_HOOK_NAME,
741 SCM_HOOK_PROCEDURES, SCM_SET_HOOK_PROCEDURES,
742 scm_make_hook_with_name), init.c (scm_boot_guile_1): Hooks no
743 longer have names. As an intermediate solution, the name
744 predicate is emulated via object properties, but use of this
745 feature is deprecated.
747 * hooks.h (scm_free_hook): Removed, as it is never defined.
749 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
751 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_FIXABLE):
752 Un-deprecated since otherwise user code can't determine whether a
753 number fits into an inum any longer. The names should be changed
756 * numbers.c (scm_big2inum): Eliminated use of SCM_UNEGFIXABLE.
758 * tags.h (SCM_UNPACK_CAR): Deprecated.
760 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
762 * filesys.h (SCM_OPDIRP), fluids.h (SCM_FLUIDP, SCM_FLUID_NUM),
763 fports.h (SCM_OPFPORTP, SCM_OPINFPORTP, SCM_OPOUTFPORTP), hooks.h
764 (SCM_HOOK_ARITY), keywords.h (SCM_KEYWORDP, SCM_KEYWORDSYM),
765 numbers.h (SCM_NUMP, SCM_BIGSIGN, SCM_BDIGITS, SCM_NUMDIGS):
766 Replace SCM_UNPACK_CAR appropriately. Don't access cells via
767 SCM_{SET}?C[AD]R unless they are known to be cons cells.
769 * gc.c (scm_heap_seg_data_t, scm_mark_locations, scm_cellp,
770 init_heap_seg): Remove unused struct member variable 'valid'.
772 2000-05-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
774 * fports.c (fport_write), ports.c (scm_markstream, scm_port_mode,
775 scm_print_port_mode), ports.h (SCM_OPPORTP, SCM_OPINPORTP,
776 SCM_OPOUTPORTP, SCM_INPUT_PORT_P, SCM_OUTPUT_PORT_P, SCM_OPENP),
777 procs.h (SCM_CLOSCAR), unif.h (SCM_ARRAY_NDIM, SCM_ARRAY_CONTP),
778 variable.h (SCM_VARIABLEP): Replace SCM_UNPACK_CAR
781 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
783 * gc.c (free_list_length), hash.c (scm_hasher), macros.c
784 (scm_macro_type), objects.c (scm_class_of), options.c
785 (scm_options), print.c (scm_iprin1), strports.c (st_seek), throw.c
786 (SCM_LAZY_CATCH_P): Replace SCM_UNPACK_CAR appropriately.
788 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
790 * eval.c (scm_macroexp, SCM_CEVAL, scm_force), tags.h: Replace
791 SCM_UNPACK_CAR with SCM_CELL_TYPE or SCM_CELL_WORD_0.
793 * eval.c (scm_force): Add documentation.
795 * eval.c (scm_force, scm_cons_source): Don't access cells via
796 SCM_{SET}?C[AD]R unless they are known to be cons cells.
798 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
800 * strings.h (SCM_NSTRINGP, SCM_NRWSTRINGP), tags.h
801 (SCM_NDOUBLE_CELLP), vectors.h (SCM_NVECTORP): Deprecated.
803 * gc.c (scm_igc), gc.h (SCM_PTR_MASK, SCM_PTR_LT): Removed #ifdef
804 nosve #endif conditionally compiled code.
806 2000-05-23 Michael Livshin <mlivshin@bigfoot.com>
808 * gc.c (scm_heap_seg_data_t): fixed comment for the `span' member.
810 2000-05-22 Michael Livshin <mlivshin@bigfoot.com>
812 * guile-doc-snarf.in: put the preprocessed file through sed to
813 trim all lines to 1024 chars. I hope it doesn't break anybody's
814 sed. we'll see. (note: this is lossy trimming, i.e. the spill
815 isn't wrapped around but actually chopped off. this seemed to me
816 safe because the current snarfer doesn't understand multi-line
817 cookies anyway. in the long term, it would be nice not to depend
818 on AWK for anything.)
820 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): reverted
821 the previous change to this macros, after deciding to torture the
824 2000-05-21 Michael Livshin <mlivshin@bigfoot.com>
826 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): brought
827 the yucky, ugly and nasty conditional compilation back. sorry,
828 but it was either that or requiring GAWK to build Guile.
829 (lots of places): removed the code that implemented the old GC
832 * init.c (scm_boot_guile_1): removed the code conditioned on
833 !GUILE_NEW_GC_SCHEME.
835 * __scm.h: (GUILE_NEW_GC_SCHEME): removed.
837 * gc.c (scm_protect_object, scm_unprotect_object): change the
838 implementation to more efficient (at least in the time complexity
839 sense). the calls should now also be thread-safe -- I suspect
840 that people expect them to be. (thanks to Han-Wen Nienhuys)
841 (lots of places): removed the code that implemented the old GC
844 * hashtab.c (scm_hash_fn_create_handle_x): add missing
845 SCM_REALLOW_INTS before return. I really wonder about the
846 possible interactions between hashtables, threads & GC. it
847 doesn't look healthy at all.
849 2000-05-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
851 * unif.c (scm_bit_count): Fixed the parameter checks. Thanks to
854 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
856 * __scm.h (SCM_DEBUG_CELL_ACCESSES), gc.h (SCM_): Added as a new
857 debug option to verify all accesses to cells actually access
860 * gc.h (SCM_VALIDATE_CELL): Added. Only performs validation if
861 SCM_DEBUG_CELL_ACCESSES is set to 1.
863 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
864 SCM_SET_CELL_OBJECT): Use SCM_VALIDATE_CELL to check every cell
867 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
869 * gh_data.c (gh_scm2chars, gh_scm2shorts, gh_scm2longs,
870 gh_scm2floats, gh_scm2doubles): Change !SCM_NIMP to SCM_IMP.
872 * gc.c (scm_cellp): Fixed and simplified.
874 * throw.c (JBJMPBUF, SETJBJMPBUF, SCM_JBDFRAME, SCM_SETJBDFRAME,
875 make_jmpbuf, scm_init_throw): Now using double cells to represent
876 jump buffers when using debug extensions.
880 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
882 * gh.h gh_data.c gh_funcs.c (gh_new_procedure*, gh_chars2byvect,
883 gh_shorts2svect, gh_longs2ivect, gh_ulongs2uvect, gh_floats2fvect,
884 gh_doubles2dvect, gh_doubles2scm, gh_define, gh_lookup,
885 gh_module_lookup): Accept const pointers as parameters.
887 * gh.h gh_data.c (gh_int2scmb): Deprecated.
889 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
891 * __scm.h (SCM_DEBUG_REST_ARGUMENT): Renamed from
892 SCM_DEBUG_REST_ARGUMENTS in order to clarify that we don't test
893 the actual arguments in the list, but rather the rest argument as
896 * validate.h (SCM_VALIDATE_REST_ARGUMENT): Added.
898 * async.c (scm_noop), eval.c (scm_map, scm_for_each), list.c
899 (scm_list_star, scm_append, scm_append_x), ports.c
900 (scm_close_all_ports_except), ramap.c (scm_array_map_x,
901 scm_array_for_each), regex-posix.c (scm_make_regexp), stacks.c
902 (scm_make_stack), strings.c (scm_string_append), struct.c
903 (scm_make_struct, scm_make_vtable_vtable): Validate rest arguments.
905 * dynl.c (DYNL_GLOBAL, sysdep_dynl_link, kw_global, sym_global,
906 scm_dynamic_link, scm_init_dynamic_linking), dynl.h
907 (scm_dynamic_link): Removed possibility to pass flags to
908 scm_dynamic_link, as it had no effect anyway.
910 * filesys.c (scm_fcntl): Made single optional rest argument into
911 a standard optional argument.
913 * hooks.c (scm_run_hook): A list of rest arguments is never
916 * list.c (scm_append, scm_append_x), stacks.c (scm_make_stack),
917 strings.c (scm_string_append): Don't perform half-hearted checks
918 to see whether the rest argument forms a proper list any more, use
919 SCM_VALIDATE_REST_ARGUMENTS instead.
921 * ports.c (scm_close_all_ports_except): Accept empty list of rest
924 * posix.c (scm_convert_exec_args), print.c (scm_simple_format):
925 Simplify verification of rest argument.
927 * stacks.c (scm_make_stack), stacks.h (scm_make_stack), throw.c
928 (ss_handler, handler_message): Make first mandatory rest argument
929 of scm_make_stack into a standard mandatory argument.
931 * unif.c (scm_transpose_array, scm_enclose_array,
932 scm_array_in_bounds_p), unif.h (scm_transpose_array,
933 scm_enclose_array, scm_array_in_bounds_p): Make first mandatory
934 rest argument into a standard mandatory argument.
936 2000-05-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
938 * __scm.h: Added SCM_DEBUG as default debug option. (Thanks to
939 Keisuke Nishida for the suggestion.) Added debug option
940 SCM_DEBUG_REST_ARGUMENTS.
942 * eval.c (scm_map, scm_for_each): Make sure all lists have the
943 same length. Also, removed redundant parameter checks.
945 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
947 * Makefile.am: Let 'make clean' remove *.x and *.doc files.
949 * __scm.h: Improved explanation of giving options to make.
951 * __scm.h (SCM_DEBUG_TYPING_STRICTNESS), tags.h
952 (SCM_STRICT_TYPING, SCM_DEBUG_TYPING_STRICTNESS): Renamed
953 SCM_STRICT_TYPING to SCM_DEBUG_TYPING_STRICTNESS and moved the
954 corresponding declaration and comment to __scm.h.
956 * _scm.h (errno), gc.h (SCM_CELLPTR, SCM_PTR_LT), numbers.c
957 (scm_remainder, scm_modulo), numbers.h (SCM_SRS, SCM_MAKINUM,
958 SCM_INUM): Removed conditionally compiled code for Turbo C.
960 * gdbint.c (gdb_maybe_valid_type_p): Eliminated call to scm_tag.
961 That check can be assumed to be redundant except for very rare
962 conditions that actually indicate broken heap data.
964 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
966 * numbers.c (scm_logcount, scm_integer_length): Reordered
969 2000-05-15 Gary Houston <ghouston@arglist.com>
971 * stime.c (scm_strftime): don't reset TZ if zone is an empty
972 string. append a "0" to the zone for TZ.
974 2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
976 * numbers.c (scm_logbit_p, scm_bit_extract): Reordered dispatch
979 (scm_bit_extract): Fixed handling of bignums.
981 2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
983 * async.c (scm_sys_gc_async_thunk), chars.h (SCM_ICHRP, SCM_ICHR,
984 SCM_MAKICHR), continuations.h (SCM_SETJMPBUF), error.c
985 (scm_sysmissing), error.h (scm_sysmissing), evalext.c

991 (scm_tc16_flo, scm_tc_flo, scm_tc_dblr, scm_tc_dblc): Wrapped
992 deprecated code between #if (SCM_DEBUG_DEPRECATED == 0) #endif.
994 * fports.c (scm_fport_buffer_add), ports.c (scm_input_port_p,
995 scm_output_port_p), print.c (scm_get_print_state), validate.h
996 (SCM_VALIDATE_CHAR): Replace use of deprecated macros
997 SCM_INPORTP, SCM_OUTPORTP, SCM_ICHRP by SCM_INPUT_PORT_P,
998 SCM_OUTPUT_PORT_P, SCM_CHARP, respectively.
1000 2000-05-14 Gary Houston <ghouston@arglist.com>
1002 * stime.c (scm_strftime): if HAVE_TM_ZONE is not defined, hack the
1003 TZ environment variable so that the %Z format returns the zone
1004 from the input vector instead of the system default.
1006 from Keisuke Nishida:
1007 * fports.c (scm_setvbuf): minor docstring fix.
1008 * ports.h (scm_generic_fgets): obsolete prototype deleted.
1010 2000-05-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
1012 * __scm.h: Added new section for debugging options.
1014 (SCM_DEBUG_DEPRECATED): If 1, no deprecated code is included to
1015 help developers to get rid of references to deprecated code.
1017 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_UNEGFIXABLE,
1018 SCM_FIXABLE, SCM_FLOBUFLEN): These macros are no longer provided
1019 as part of the interface and are marked as deprecated in the
1022 * numbers.c (scm_make_real, scm_make_complex): Inlined the
1023 corresponding macros SCM_NEWREAL and SCM_NEWCOMPLEX,
1026 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX, SCM_INEXP, SCM_CPLXP,
1027 SCM_REAL, SCM_IMAG, SCM_REALPART, scm_makdbl, SCM_SINGP,
1028 SCM_NO_BIGDIG, SCM_NUM2DBL, scm_dblproc): Deprecated.
1030 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1032 * gc.h (scm_cell, SCM_CELL_WORD, SCM_CELL_OBJECT,
1033 SCM_SET_CELL_WORD, SCM_SET_CELL_OBJECT): Scheme cells now consist
1034 of two scm_bits_t values instead of two SCM values, because it is
1035 legal for cell entries to hold values that are not scheme objects.
1037 (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR):
1038 Use SCM_SETC[AD]R to modify contents of pairs.
1040 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1042 * numbers.c (IS_INF, isfinite): Added FIXME comment.
1044 (scm_abs, scm_magnitude): Make these two independent of each
1045 other. scm_abs now reports an error if given a complex argument.
1047 (scm_istr2flo, scm_integer_p). Use SCM_REAL_VALUE instead of
1048 SCM_REALPART if the object is known to be real.
1050 (scm_init_numbers): No need to use SCM_NEWREAL macro for speed
1053 * numbers.h (SCM_SINGP): Set to 0 instead of SCM_BOOL_F.
1055 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1057 * eq.c (scm_eqv_p): Separate handling of real and complex
1058 values. Remove #ifdef SCM_BIGDIG #endif test.

1061 gh_scm2doubles), hash.c (scm_hasher), ramap.c (scm_array_fill_int,
1062 ramap_rp, scm_array_map_x), random.c (vector_scale,
1063 vector_sum_squares), unif.c (scm_make_uve, scm_array_p,
1064 scm_array_set_x): Use SCM_REAL_VALUE instead of SCM_REALPART if
1065 the object is known to be real. Use SCM_COMPLEXP instead of
1066 deprecated SCM_CPLXP. Use SCM_INEXACTP instead of deprecated
1069 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1071 * numbers.c: No need to include unif.h.
1073 (IS_INF): Returned to old test for now: x == x + 1 will not work
1074 for large numbers due to rounding errors.
1075 Thanks to Kalle Olavi Niemitalo.
1077 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
1079 * numbers.c (scm_divbigdig): Removed outdated comment.
1081 (scm_number_to_string, scm_string_to_number, scm_number_p,
1082 scm_real_p, scm_integer_p, scm_inexact_p, scm_gr_p, scm_leq_p,
1083 scm_geq_p, scm_make_rectangular, scm_make_polar,
1084 scm_inexact_to_exact): Added comments.

1088 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
1090 * numbers.c (IS_INF): The new test is x == x + 1. The old test
1091 x == x/2 did not work for zero values. Thanks to Han-Wen Nienhuys
1094 (scm_number_to_string, scm_sum, scm_difference, scm_two_doubles,
1095 scm_num2long, scm_num2long_long, scm_num2ulong): Reordered
1098 2000-05-09 Marius Vollmer <mvo@zagadka.ping.de>
1100 * scmsigs.c (take_signal): Execute SCM_ASYNC_TICK for SIGSEGV,
1101 SIGILL and SIGBUS signals. These signals are not continuable and
1102 must be handled for real right away.
1104 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1106 * numbers.c (scm_zero_p, scm_positive_p, scm_negative_p,
1107 scm_real_part, scm_imag_part, scm_magnitude,
1108 scm_inexact_to_exact): Reordered dispatch sequence.
1110 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1112 * feature.c: No need to include "libguile/smob.h"
1114 (scm_loc_features, features, scm_add_feature, scm_init_feature):
1115 Removed variable 'scm_loc_features' as a pointer to the SCM value
1116 holding the features list. Using variable 'features' instead,
1117 which holds the interned pair. Thus, SCM_SETCDR can be used
1118 instead of pointer trickery.
1120 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1122 * alist.c (scm_acons): Use SCM{_SET}?_CELL_OBJECT as long as a
1123 cell is not known to be a valid pair.
1125 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1127 * eval.c (ASRTSYNTAX, scm_m_body, scm_m_letrec1): Removed
1128 ASRTSYNTAX. Using SCM_ASSYNT instead.

1134 (bodycheck): Removed.
1136 * stacks.c (stack_depth, read_frame, read_frames): Removed
1137 redundant calculation of size, minimized some variable scopes.
1139 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1141 * pairs.c (scm_cons, scm_cons2): Use SCM{_SET}?_CELL_OBJECT as
1142 long as a cell is not known to be a valid pair.
1144 (scm_pair_p): Eliminated redundant SCM_IMP test.
1146 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1148 * eval.c (scm_m_body, scm_macroexp, unmemocopy, scm_eval_args,
1149 scm_deval_args): Eliminated redundant SCM_IMP tests.
1151 * hashtab.c (scm_ihashx, scm_sloppy_assx, scm_delx_x), weaks.c
1152 (scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
1153 scm_make_doubly_weak_hash_table): Fixed critical sections.
1154 Thanks to Keisuke Nishida.
1156 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1158 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest):
1159 Fixed some goto-related initialization bugs (introduced by me).
1161 2000-05-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
1163 * numbers.h (SCM_INUM0): Uses SCM_MAKINUM instead of SCM_PACK.
1165 * dynl.c (dynl_obj, DYNL_OBJ, get_dynl_obj): Removed.
1167 (DYNL_FILENAME, DYNL_HANDLE): Use SCM_CELL... macros instead of
1170 (SET_DYNL_HANDLE): Added.
1172 (scm_dynamic_object_p): Simplified.
1174 (scm_dynamic_unlink, scm_dynamic_func): Changed comment. Deliver
1175 better error message when accessing unlinked dynamic objects.
1176 Eliminated call to get_dynl_obj.
1178 2000-05-03 Marius Vollmer <mvo@zagadka.ping.de>
1180 * scmsigs.c (orig_handlers) [!HAVE_SIGACTION]: Fix declaration to
1181 be an array of function pointers instead of being a pointer to an
1182 array returning function. Thanks to Kalle Olavi Niemitalo!
1184 2000-05-03 Dirk Herrmann <D.Herrmann@tu-bs.de>
1186 * numbers.c (scm_divbigbig, scm_divbigint), numbers.h
1187 (scm_divbigbig, scm_divbigint): Don't return zero any more to
1188 indicate that a division has a remainder, return SCM_UNDEFINED
1189 instead. It is improbable that anyone actually used these
1190 functions outside of numbers.c. For this reason and due to the
1191 change in behaviour the functions are static now. Thus, if
1192 surprisingly there are users of these functions they will at least
1195 * numbers.c: Removed #ifdef SCM_BIGDIG #endif in those functions,
1196 that already have a clean dispatch order. Note: SCM_BIGDIG is
1199 * numbers.c (scm_inexact_p): Simplified.
1201 * numbers.c (scm_num_eq_p, scm_less_p, scm_max, scm_min,
1202 scm_product, scm_num2dbl, scm_angle): Reordered dispatch
1203 sequence, thereby fixing some comparisons of SCM values with
1206 * numbers.c (scm_divide): Division by zero of inums leads to an
1207 error now. (Formerly, an infinite number was returned.)
1209 Respect the fact, that scm_divbigbig does now return SCM_UNDEFINED
1210 if a division has a remainder.
1212 2000-05-02 Gary Houston <ghouston@arglist.com>
1214 * Makefile.am (INCLUDES): add ${INCLTDL} (thanks to Tim Mooney).
1216 2000-05-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
1218 * numbers.c (scm_logtest, scm_division): Reordered dispatch
1219 sequence, thereby fixing some comparisons of SCM values with

1234 call to scm_makdbl with a call to scm_make_real or
1235 scm_make_complex, depending on whether the imaginary part is known
1238 2000-05-01 Gary Houston <ghouston@arglist.com>
1240 * scmsigs.c: fix the definition of orig_handlers for the case
1241 that HAVE_SIGACTION is not defined (thanks to
1242 Kalle Olavi Niemitalo).
1244 * Makefile.am: remove include_HEADERS (was libguile.h)
1245 libguile.h: moved to top level directory.
1247 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1249 * numbers.c (SCM_SWAP): Moved to the top of the file to allow for
1252 * numbers.c (scm_modulo, scm_gcd, scm_lcm, scm_logand, scm_logior,

1263 occur anywhere else throughout guile.
1265 * numbers.c (scm_quotient): Fixed parameter number in error
1268 * numbers.c (scm_remainder): Reordered dispatch sequence.
1270 2000-04-25 Gary Houston <ghouston@arglist.com>

1285 * procs.c (scm_init_iprocs), procs.h (scm_subr, scm_iproc,
1286 scm_dsubr, scm_init_iprocs): Removed.
1288 * procs.h (SCM_SUBRF, SCM_DSUBRF): Access the cell words
1289 directly instead of casting a cell to a C struct.
1291 2000-04-22 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1293 Better modularization of GC extensions through new C level GC
1296 * weaks.c (scm_weaks_prehistory): New function: Add

1321 scm_after_gc_c_hook): New C level hooks.
1322 (scm_after_gc_hook): New Scheme level hook.
1323 (scm_gc_sweep): Moved scanning of weak vectors to weaks.c.

1351 the root build directory.
1353 * numbers.c (scm_odd_p, scm_even_p): Use SCM_WRONG_TYPE_ARG
1354 instead of SCM_ASSERT (0, ...). (Some compilers will complain

1375 scm_quotient): Reordered dispatch sequence to first handle
1376 immediates, second handle bignums and finally handle generic
1377 functions respectively signal wrong type arguments. Hopefully
1378 this will allow for easier separation when goops is integrated.
1380 2000-04-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1382 * gc.c (which_seg): Use SCM2PTR to convert a non immediate SCM

1623 * objects.h: Don't redeclare scm_call_generic_0 and

1662 * validate.h: move async validation macros to async.c (nobody else
1663 needs them anyway), and rename them.
1665 2000-04-04 Michael Livshin <mlivshin@bigfoot.com>
1667 * async.h: kill the scm_async_t struct. having a heap cell
1668 pretending to be a C struct is not helthy, and is not needed here
1669 anyway, as asyncs happily fit in one heap cell.
1671 * async.c: reflect the fact that asyncs are now represented by
1672 single heap cell each.

1736 2000-04-03 Michael Livshin <mlivshin@bigfoot.com>
1738 * guardians.c (scm_guardian_zombify): mark all zombies in a
1739 separate loop after processing all the currently known live
1740 guardians, so as to not introduce order dependencies (thanks to
1741 Gary Houston). note that the order problems are still there if
1742 some guardians are themselves zombies, but that's a sick case that
1743 I'm not going to worry about.
1744 also, make another outer loop to process zombified
1745 guardians (which are uncovered while marking zombies).

1892 (mother): New function.
1893 (coop_create): New thread spawning mechanism which uses a "mother

2052 SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR): Moved here from
2055 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2057 * tags.h (SCM_STRICT_TYPING): New macro that, if defined,
2058 activates strict compile time type checking for variables of
2060 (SCM, SCM_PACK, SCM_UNPACK): Define according to whether
2061 SCM_STRICT_TYPING or SCM_VOIDP_TEST are defined.
2062 (SCM_EQ_P): Defined as a macro equivalent for eq?.
2064 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2066 * tags.h (SCM_POINTERS_MUNGED): Removed.
2068 * gc.c (scm_gc_sweep, init_heap_seg): Removed use of
2069 SCM_POINTERS_MUNGED, thus fixing some illegal casts to SCM.
2071 2000-03-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
2073 * pairs.h (SCM_CELL_OBJECT, SCM_CELL_OBJECT_[0-3],
2074 SCM_SET_CELL_OBJECT, SCM_SET_CELL_OBJECT_[0-3], SCM_CELL_TYPE,
2075 SCM_SET_CELL_TYPE): Added a set of low level macros for accessing
2077 (SCM_CELL_WORD_[0-3]): Renamed from the SCM_CELL_WORD[0-3].
2079 * procs.h, procs.c: Instead of SCM_{SET_}?CELL_WORD[12], use the
2080 newly introduced SCM_{SET_}?CELL_OBJECT_[12] macros.
2082 2000-03-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2084 * tags.h: Disabled definition of SCM_VOIDP_TEST.
2086 Defining SCM as void * introduces problems which haven't been
2087 handled yet. Developers who work with these issues can enable it
2088 in their working copies.
2090 Disabling this definition exposes a set of newly introduced and
2091 older misuses of types which causes warning messages during
2092 compilation. We'll fix this successively.
2094 * gc.c (scm_mark_locations): Changed * (SCM **) X --> * (SCM *) X
2095 in order to obtain a value of type SCM.
2096 (scm_cellp): Updated with new changes to scm_mark_locations.
2098 * continuations.h (SCM_SETJMPBUF): Cast second arg into SCM.
2100 * continuations.c (scm_make_cont): Removed cast of size_t into
2103 * symbols.h (SCM_SETCHARS): Cast second arg into SCM.
2105 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
2107 * numbers.h (SCM_SETNUMDIGS): Use SCM_BIGSIZEFIELD macro for
2108 shifting, not constant. Thanks to Dale P. Smith.
2110 * numbers.c (scm_sum, scm_difference): Don't test a SCM value
2111 for being less than zero. Decode it to a C value first. Again,
2114 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
2116 * numbers.h, ramap.c, struct.h, vectors.h: Don't use SCM2PTR for
2117 non scheme values. If raw data is stored in SCM variables, it has
2118 to be accessed using SCM_UNPACK until a better solution is found.
2120 2000-03-22 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2122 * tags.h (SCM_ECONSP, SCM_NECONSP): More corrections of
2123 pointer-arithmetic induced by the SCM_PACK/UNPACK change.
2125 * print.c (scm_iprin1): SCM_PACK/UNPACK corrections.
2127 * gc.c (scm_gc_sweep): SCM_PACK/UNPACK corrections.
2129 * eval.c (SCM_CEVAL, scm_unmemocar): SCM_PACK/UNPACK corrections.
2131 * dynwind.c (scm_swap_bindings): SCM_PACK/UNPACK corrections.
2133 * async.c, __scm.h: Removed lots of the old async click logic. It
2134 is possible to reinsert it by defining GUILE_OLD_ASYNC_CLICK in
2135 __scm.h. Let's try this out and dump the old code after the
2136 threads reorganization.
2137 (set-tick-rate, set-switch-rate): Conditionally removed.
2139 2000-03-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2141 * gc.c (scm_gc_mark): Bugfix 1: The recent SCM_PACK/UNPACK change
2142 made SCM values into pointers. This turned an arithmetic
2143 computation of the address of the vcell into a pointer-arithmetic
2144 one, thereby screwing up marking of structs.
2145 Bugfix 2: Removed incompletely introduced loop variable `j' used
2146 when protecting the tail array of a struct.
2148 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2150 * struct.h (SCM_STRUCT_DATA): Don't cast SCM values to pointers.
2152 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2154 * symbols.h, symbols.c (scm_strhash): Declare the string
2155 parameter as constant, since it is not modified.
2157 * symbols.c (scm_intern_obarray_soft,
2158 scm_sysintern0_no_module_lookup): Can now pass constant strings
2159 to scm_strhash without need for casting.
2161 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2163 * vectors.h (SCM_VELTS, SCM_VELTS_AS_STACKITEMS): Don't cast SCM
2164 values to pointers. Use SCM2PTR instead.
2166 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2168 * async.c (scm_set_tick_rate, scm_set_switch_rate): Don't unpack
2169 results of SCM_INUM.
2171 2000-03-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2173 * init.c (scm_boot_guile_1): Renamed GUILE_GC_TRIGGER_1 -->
2174 GUILE_MIN_YIELD_1, GUILE_GC_TRIGGER_2 --> GUILE_MIN_YIELD_2.
2175 GUILE_MIN_YIELD_X now take *positive* fractions of heap size.
2177 * gc.c, gc.h (SCM_MIN_YIELD_1, SCM_MIN_YIELD_2,
2178 min_yield_fraction, min_yield, adjust_min_yield): Renamed from
2179 SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2, gc_trigger_fraction,
2180 gc_trigger, adjust_gc_trigger.
2182 * gc.c (alloc_some_heap): Further improvement of minimal heap size
2184 (SCM_MAX): New macro.
2185 (scm_freelist_t): New field: collected_1. Previous amount of
2187 (gc_sweep_freelist_finish): Trigger based on two last values of
2188 freelist->collected to avoid unnecessary allocation due to
2190 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2):
2191 Adjusted to 45000 cells, 40% and 40%. Gives quick startup
2192 without extra heap allocation.
2194 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2196 * numbers.h (SCM_MAKINUM): The parameter to SCM_MAKINUM should
2197 already be a C value. No need to unpack it.
2199 * numbers.c (scm_long_long2num): Cast the parameter to scm_bits_t
2200 if we know it fits into an inum.
2202 * ramap.c (ramap_rp): An scm_tc7_[ui]vect object does point to a
2203 field of long values. In contrast, SCM_VELTS accesses a field of
2206 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2208 * gc.c (scm_gc_stats): Inserted explanation of local_scm_mtrigger
2210 (scm_gc_yield_1): New variable: Holds previous yield. Used to
2211 make better judgements.
2212 (gc_sweep_freelist_finish): Inserted explanation of use of
2215 * print.h, stacks.h, options.c, options.h: Changed C++
2218 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2220 * tags.h (SCM2PTR, PTR2SCM): Use SCM_PACK / SCM_UNPACK correctly.
2222 * numbers.h (SCM_INUMP, SCM_MAKINUM, SCM_INUM0, SCM_COMPLEX_REAL,
2223 SCM_COMPLEX_IMAG, SCM_NUMP, SCM_BDIGITS): Use SCM_PACK /
2224 SCM_UNPACK / SCM2PTR correctly.
2226 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2228 * gc.c (adjust_gc_trigger): Improved documentation.
2229 (alloc_some_heap): Since gc_trigger is used against
2230 freelist->collected, this is the value which should be used to
2231 predict minimum growth.
2233 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2235 * eval.h: Fix mixup of packed/unpacked SCM values. (Thanks
2236 Thien-Thi Nguyen for the patch.)
2238 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2240 * numbers.c (scm_ash): Fixed typing problems with the second
2241 parameter and added some documentation. (Thanks Thien-Thi Nguyen
2242 for indicating the problem.)
2244 2000-03-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2246 * gc.c, gc.h (scm_gc_yield): New variable.
2247 (adjust_gc_trigger): Use scm_gc_yield.
2248 (alloc_some_heap): Use scm_gc_yield instead of
2249 scm_gc_cells_collected.
2251 * coop-threads.c: Addd #include "root.h", #include "strings.h".
2253 * debug.c: Added #include "root.h". (Thanks to Thien-Thi Nguyen.)
2255 * gc.c (scm_gc_for_newcell, adjust_gc_trigger): Improved GC
2256 trigger adjustmeant: Take yield (freed cells) for all freelists
2258 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Tuned
2259 to 50000 cell heap with 45% trigger.
2260 (scm_gc_cells_collected): Reintroduced.
2261 (SCM_HEAP_SIZE): New macro.
2262 (scm_gc_sweep): Reintroduced correct computation of
2263 scm_cells_allocated.
2264 (scm_freelist_t): Corrected commentary for field `cluster_size':
2265 Clustersize counts objects, not cells; New member
2266 `clusters_allocated'.
2268 2000-03-19 Michael Livshin <mlivshin@bigfoot.com>
2270 * *.[hc]: add Emacs magic at the end of file, to ensure GNU
2273 2000-03-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2275 * threads.h: Added #include "libguile/throw.h". (Thanks to
2278 2000-03-18 Michael Livshin <mlivshin@bigfoot.com>
2280 * tags.h: (SCM_DOUBLE_CELLP, SCM_NDOUBLE_CELLP): new macros (bad
2281 names, anyone got any better ones?)
2283 * gc.h: (typedef struct scm_freelist_t) remove from here.
2285 * gc.c: (CELL_UP, CELL_DN) made these macros take additional
2286 parameter (the span).
2287 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK) new macros.
2288 (typedef struct scm_freelist_t) moved here from gc.h, it had no
2289 business being externally visible.
2290 (typedef struct scm_heap_seg_data_t) renamed from
2291 scm_heap_seg_data, to be style-compliant.
2292 (scm_mark_locations) if the possible pointer points to a
2293 double-cell, check that it's properly aligned.
2294 (init_heap_seg) align double-cells properly, work with the
2295 assumption that the segment size divides cleanly by cluster size.
2296 (round_to_cluster_size) new function.
2297 (alloc_some_heap, make_initial_segment) use round_to_cluster_size
2298 to satisfy the new init_heap_seg invariant.
2300 2000-03-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
2302 * _scm.h: Don't include async.h everywhere...

2357 2000-03-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2359 * gc.c, gc.h: Cleanup of the change of 2000-03-15.
2360 Cluster sizes are now independent of GC trigger values.
2361 GUILE_GC_TRIGGER_n can now specify a relative trigger value:
2362 A negative integer gives fraction of total heap size in percent.
2363 (SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Default values set to -40.
2365 * init.c (scm_boot_guile_1): Introduced new variable
2366 GUILE_MAX_SEGMENT_SIZE; New environment variable names:
2367 GUILE_INIT_SEGMENT_SIZE_1, GUILE_GC_TRIGGER_1,
2368 GUILE_INIT_SEGMENT_SIZE_2, GUILE_GC_TRIGGER_2
2370 2000-03-16 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2372 * __scm.h (GC_FREE_SEGMENTS): Disable this until we have made
2373 freeing of segment work with the new GC scheme. (Thanks to
2374 Michael Livshin.) Oops, also happened to make GUILE_NEW_GC_SCHEME
2375 the default, but I'll let this change stay in CVS Guile since this
2376 code is not expected to contain serious bugs.
2378 2000-03-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2380 * gc.c, gc.h (scm_map_free_list): Define also if GUILE_DEBUG is
2382 (scm_free_list_length): New procedure (GUILE_DEBUG).
2383 Fixed a small but serious bug introduced by the previous change.
2385 * gc.c (scm_gc_sweep): Moved variable n_objects to inner sweep
2386 loop and declare as register.
2388 * gc.c (scm_gc_sweep): Sigh... forgot to clear private freelists
2391 Wed Mar 15 08:27:04 2000 Greg J. Badros <gjb@cs.washington.edu>
2393 * fluids.c: Docstring patch from Keisuke Nishida. Some
2394 reindentation, too, and a couple formals renamed. Should
2395 fluid-set! return UNSPECIFIED instead of a value?
2397 Wed Mar 15 08:24:58 2000 Greg J. Badros <gjb@cs.washington.edu>
2399 * Makefile.am: Separate out DOT_X_FILES and DOT_DOC_FILES, and
2400 generate the latter from the concrete listing of the former. Then
2401 make guile-procedures.txt depend on DOT_DOC_FILES instead of
2402 *.doc, so that rebuilding it works.
2404 Wed Mar 15 08:12:14 2000 Greg J. Badros <gjb@cs.washington.edu>
2406 * libguile.h: Include libguile/validate.h. Thanks Keisuke Nishida!
2408 * guile-snarf.awk.in: Replace docstring line-ending \n" and \n\n"
2409 with nothing and \n, respectively. Thanks Keisuke Nishida for
2410 noticing this problem.
2412 2000-03-15 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2414 * __scm.h (GUILE_NEW_GC_SCHEME): Define this if you want to test a
2415 new way of allocating heap. It makes Guile fast, but still
2418 * gc.c, gc.h, pairs.h, init.c: Implementation of a new way of
2419 allocating heap. The basic idea is to trigger GC every Nth
2420 allocated cell and grow heap when free list runs out. The scheme
2421 has been extended so that GC isn't triggered until all remaining
2422 cells are used. The implementation is also prepared for
2423 development in the direction of POSIX threads.
2425 * gc.c (SCM_EXPHEAP): In order to grow by a factor of 1.5,
2426 SCM_EXPHEAP should return half of the heap size.
2428 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2430 The following change to init.c is only enabled if Guile was
2431 configured with --enable-guile-debug.
2433 * init.c (scm_i_getenv_int): New function.
2434 (scm_boot_guile_1): Use the environment variables
2435 GUILE_INIT_HEAP_SIZE, GUILE_INIT_HEAP_SIZE2 to select heap size if
2436 they exist. (This may be replaced by a Scheme level mechanism in
2439 * objprop.c (s_scm_set_object_property_x): Use scm_assq instead of
2440 scm_assoc. (Thanks to Keisuke Nishida.)
2442 2000-03-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2444 * eval.c, lang.c, lang.h (scm_lisp_nil, scm_lisp_t): Renamed from
2445 scm_nil, scm_t. (Thanks to Keisuke Nishida.)
2447 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2449 * init.c (scm_boot_guile_1): Use same initial segment size for
2450 1-word and 2-word segments. Having the smaller size causes Guile
2451 to GC too often. Obviously something needs to be done to allow
2452 for a smaller 2-word segment without this to happen. (The amount
2453 of heap for each type should be automatically adapted to the
2454 application somehow.)
2456 [Almost all of these changes should be documented in the NEWS
2459 * gc.h (scm_freelist_t): New type.
2461 * pairs.h (SCM_NEWCELL, SCM_NEWCELL2): Use new style freelists.
2463 * gc.c (SCM_INIT_HEAP_SIZE): Changed from 32768 --> 40000 so that
2464 all of Guile basics fits into one segment and there suitable room
2466 (SCM_EXPHEAP): Now takes an argument. Grow by a factor of 1.5
2468 (scm_freelist, scm_freelist2): Now of type scm_freelist_t.
2469 Freelists now contains information about object span, cells
2470 collected and amount of cells in heap segments belonging to the
2472 (scm_heap_size, scm_gc_cells_collected): Removed.
2474 * init.c (scm_boot_guile_1): Make 2-word segment 8K (512 cells).
2476 * Makefile.am (libguile_la_LDFLAGS): Bumped library version
2479 * __scm.h eq.c, eval.c, gc.c, gc.h, gh_data, hash.c, numbers.c,
2480 numbers.h, objects.c, ramap.c, random.c, unif.c, unif.h: Extensive
2481 rewrite of handling of real and complex numbers.
2482 (SCM_FLOATS, SCM_SINGLES): These #ifdef conditionals have been
2483 removed along with the support for floats. (Float vectors are
2486 * tags.h (scm_tcs_bignums): Removed.
2487 (scm_tc16_bigpos, scm_tc16_bigneg): Replaced by scm_tc16_big.
2488 Use SCM_BIGSIGN(x) to test for sign!
2489 (scm_tc16_big): The new bignum type.
2490 (SCM_REAL_PART, SCM_IMAG_PART): Removed.
2492 * numbers.h (SCM_BIGSIGN): Sign moved to bit 16.
2493 (scm_makdbl): Deprecated.
2494 (SCM_NEWREAL, SCM_NEWCOMPLEX): New macros.
2495 (SCM_SINGP): Deprecated.
2497 (SCM_INEXP, SCM_CPLXP): Deprecated.
2498 (SCM_INEXACTP, SCM_COMPLEXP): New macros.
2499 (SCM_COMPLEX_REAL, SCM_COMPLEX_IMAG): Renamed from
2500 SCM_REAL, SCM_IMAG (and now only valid for complex numbers).
2501 (SCM_REAL, SCM_IMAG): New, *deprecated*, selectors which work both
2502 for doubles and complex numbers.
2503 (SCM_REAL_VALUE): New selector for doubles.
2504 (scm_double_t, scm_complex_t): New types.
2507 * numbers.c (scm_floprint, scm_floequal): Removed.
2508 (scm_print_real, scm_print_complex, scm_real_equalp,
2509 scm_complex_equalp): New functions.
2511 * unif.c (scm_makflo): Removed.
2513 * smob.h (SCM_SMOB_PREDICATE): New macro.
2514 (SCM_NEWSMOB2, SCM_RETURN_NEWSMOB2, SCM_NEWSMOB3,
2515 SCM_RETURN_NEWSMOB3): New macros.
2517 1999-11-21 Michael Livshin <mlivshin@bigfoot.com>
2519 The following changes implement primitive support for double cells
2520 (i.e. four-word cells) and change the representation of some
2521 things to multi-cells instead of cons+malloc. (Applied and
2524 * pairs.h (SCM_NEWCELL2): double-cell variants of SCM_NEWCELL.
2525 (SCM_CELL_WORD, SCM_CELL_WORDLOC, SCM_SET_CELL_WORD): primitive
2526 multi-cell access macros (used by the ones below).
2527 (SCM_CELL_WORD[0-3], SCM_SET_CELL_WORD[0-3]): multi-cell access
2530 * gc.c (scm_freelist2): multi-cell freelists.
2531 (inner_map_free_list): map_free_list, parameterized on ncells.
2532 "nn cells in segment mm" was misleading for ncells > 1; changed to
2533 "objects". still print cells too, though.
2534 (scm_map_free_list): rewritten using inner_map_free_list.
2535 (scm_check_freelist): get freelist as parameter, since now we have
2537 (scm_debug_newcell2): multi-cell variants of
2539 (scm_gc_for_newcell): take ncells and freelist pointer as
2541 (scm_gc_mark): add case for tc7_pws (procedures with setters are
2543 (scm_gc_sweep): don't free the float data, since it's not malloced
2545 (init_heap_seg): didn't understand what n_new_objects stood for,
2546 so changed to n_new_cells.
2547 (make_initial_segment): new function, makes an initial segment
2548 according to given ncells.
2549 (scm_init_storage): call make_initial_segment, for ncells={1,2,3}.
2551 * numbers.c (scm_makdbl): no malloc'ing needed, so the
2552 {DEFER,ALLOW}_INTS thing removed.
2554 * numbers.h (struct scm_dbl): changed to represent a double cell,
2555 with the number in the second half.
2557 * dynwind.c: changed the wind-guards representation to double
2560 * procs.c, procs.h: changed the procedure-with-setter representation
2563 * async.c, async.h: made async representation a double cell.
2565 * dynl.c: made dynamic_obj representation a double cell.
2567 2000-03-13 Gary Houston <ghouston@arglist.com>
2569 * ports.c (flush_void_port): renamed to flush_port_default.
2570 (end_input_void_port): renamed to end_input_default.
2572 * init.c (scm_standard_stream_to_port): create a void port instead
2573 of opening /dev/null if the standard file descriptors are bad.
2574 advantages: no portability problems, doesn't waste a file descriptor,
2575 simplifies the code (thanks to Marius for the idea).
2577 * vports.c (s_scm_make_soft_port): call scm_port_non_buffer.
2579 * void ports: make reading from a void port give EOF instead of
2581 * ports.c (s_scm_sys_make_void_port): modified docstring.
2582 (fill_input_void_port): new proc.
2583 (scm_init_ports): set up fill_input_void_port.
2584 * ports.c (scm_port_non_buffer): new proc.
2585 (scm_void_port): call scm_port_non_buffer.
2587 * fports.c (scm_setvbuf): docstring: remove the fcntl documentation
2588 which was incorrectly appended.
2590 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2592 * guile-doc-snarf.in: Don't use absolute path for `sed'. (Note
2593 that we can't use autoconf for this. Autoconf itself relies on
2594 the existence of `sed' somewhere on your path.) (Thanks to Dirk
2597 2000-03-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2599 * Makefile.am (libguile_la_SOURCES): Moved iselect.c here from
2600 EXTRA_libguile_la_SOURCES.
2602 * iselect.h: Always declare scm_internal_select.
2604 * iselect.c (scm_internal_select): Added SCM_ASYNC_TICK at the
2605 end. Also let scm_internal_select be a real function also when
2608 * __scm.h (SCM_TICK): Oops! Forgot to put SCM_ASYNC_TICK here...
2610 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2612 * __scm.h (SCM_ALLOW_INTS, SCM_REALLOW_INTS): Removed call to
2613 SCM_ASYNC_TICK. (This is a preparation for POSIX threads support,
2614 and kind of an experiment: Will this cause problems?)
2616 Sun Mar 12 13:26:30 2000 Greg J. Badros <gjb@cs.washington.edu>
2618 * Makefile.am: Added *.doc to DISTCLEANFILES.
2620 2000-03-12 Gary Houston <ghouston@arglist.com>
2622 * fports.c (scm_fdes_to_port): call fcntl F_GETFL to test that
2623 the fdes is valid before doing anything else. check that
2624 the file descriptor supports the modes required.
2625 (scm_fport_buffer_add): don't throw an error if fstat doesn't
2626 work: just use the default buffer size.
2628 * throw.c: change an outdated comment about scm_internal_catch
2629 BODY: it doesn't take a jumpbuf arg.
2631 * init.c (scm_standard_stream_to_port): install a handler in case
2632 scm_fdes_to_port throws an error. don't check here whether the
2633 file descriptor is valid, since scm_fdes_to_port will do that.
2634 set the revealed count depending on whether the port got the
2635 standard file descriptor.
2636 (stream_body_data): new type.
2637 (stream_body, stream_handler): new procs.
2639 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2641 * stacks.c, stacks.h, struct.c, tags.h, unif.c (scm_bits_t):
2642 Renamed from SCMWORD.
2644 * tags.h (SCM_NCELLP): Removed (SCMWORD).
2646 * arbiters.c (SCM_ARB_LOCKED): Use SCM_UNPACK_CAR.
2648 * async.c, boolean.h, debug.c, dynl.c, dynwind.c, eval.c, eval.h,
2649 feature.h, filesys.h, fluids.h, fports.c, fports.h, gc.c, gc.h,
2650 hash.c, keywords.h, macros.c, numbers.c, numbers.h, objects.c,
2651 objects.h, options.c, pairs.h, ports.c, ports.h, print.c,
2652 procs.h, ramap.c, read.c, smob.c, smob.h, srcprop.h, stacks.c,
2653 stacks.h, strports.c, struct.c, struct.h, tag.c, tags.h,
2654 throw.c, unif.c, unif.h, variable.h, vectors.h, weaks.c,
2655 weaks.h (SCM_PACK, SCM_UNPACK, SCM_UNPACK_CAR): Renamed from
2656 SCM_ASSCM, SCM_ASWORD, SCM_CARW).
2658 * numbers.h (SCM_SRS, SCM_INUM): Corrected SCM_ASSCM/ASWORD fixes.
2660 * alist.c, eval.c, net_db.c, posix.c, print.c, snarf.h, struct.c,
2661 tags.h: Fixed copyright notices.
2663 * struct.c, coop-threads.c: SCM_ASSCM/ASWORD fixes.
2665 2000-03-12 Marius Vollmer <mvo@zagadka.ping.de>
2667 * init.c (scm_standard_stream_to_port): Check whether the file
2668 descriptor is valid and substitute "/dev/null" when not.
2670 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2672 * coop-defs.h (struct timespec): Conditionally defined.
2674 * coop.c (coop_condition_variable_timed_wait_mutex): Use ETIMEDOUT
2677 * readline.c (match_paren): Bugfix: First arg to select is not
2678 number of descriptors but the number of the highest descriptor +
2681 This is a preliminary attempt at a cleanup of the threads support
2682 code. It moves things to better places, makes arguments more
2683 consistent with the POSIX API (which is used in GNOME's glib), and
2684 adds new functionality.
2686 * readline.c (scm_init_readline): Added new arg to scm_init_mutex.
2688 * coop-defs.h (scm_mutex_trylock): New macro: alias for
2690 (scm_cond_init): Changed definition to
2691 coop_new_condition_variable_init.
2693 * coop.c: #include <errno.h>
2694 (coop_timeout_qinsert): Moved here from iselect.c
2695 (coop_new_mutex_init, coop_new_condition_variable_init): New
2696 functions. The strange names are temporary. Use scm_mutex_init
2697 and scm_cond_init instead.
2698 (coop_mutex_trylock): New function. Uses errno.h:EBUSY. errno.h
2699 is ANSI C, but should we check for individual error codes in
2701 (coop_condition_variable_timed_wait_mutex): New function.
2702 (coop_key_create, coop_setspecific, coop_getspecific,
2703 coop_key_delete): New functions.
2705 * iselect.c (coop_timout_qinsert): Moved to coop.c
2707 2000-03-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2709 * pairs.h (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR,
2710 SCM_SETOR_CDR): Corrected SCM_ASSCM/WORD fixes.
2712 * tags.h (SCM_VOIDP_TEST): Renamed from VOIDP_TEST.
2715 * objects.h (SCM_CLASS_FLAGS, SCM_OBJ_CLASS_FLAGS,
2716 SCM_SET_CLASS_INSTANCE_SIZE), struct.h (SCM_STRUCT_VTABLE_DATA),
2717 proc.h (SCM_CLOSCAR): SCM_ASSCM/WORD fixes.
2719 * eval.c (scm_lookupcar1): Inserted SCM_ASWORD in expressions
2722 2000-03-11 Dale P. Smith <dpsm@en.com>, applied by Greg J. Badros, <gjb@cs.washington.edu>
2724 * numbers.c (scm_copy_big_dec, scm_copy_smaller, scm_big_ior,
2725 scm_big_xor, scm_big_and, scm_big_test): Added new lowlevel bignum
2726 logical functions from SCM.
2728 (logand, logior, logxor, logtest, logbit?): Extended scheme
2729 logical functions to use bignums from SCM.
2731 (lognot): Removed call to `SCM_VALIDATE_INUM' that prevented
2732 lognot from using bignums.
2734 Thu Mar 9 11:33:25 2000 Greg J. Badros <gjb@cs.washington.edu>
2736 * vectors.h (SCM_VELTS_AS_STACKITEMS): Added this macro to help in
2737 eliminating some warnings.
2739 * unif.c, strports.c, print.c, options.c: Fix some warnings on
2742 * gc.c, gc.h: Added scm_return_first_int(), and added comment re:
2743 what the scm_return_first* functions do.
2745 2000-03-09 Han-Wen Nienhuys <hanwen@cs.uu.nl>, applied by Greg J. Badros, <gjb@cs.washington.edu>
2747 * libguile/*.[ch]: make a distinction between SCM as a generic
2748 name for a Scheme object (now a void*), and SCM as 32 bit word for
2749 storing tags and immediates (now a long int). Introduced
2750 SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
2751 code in the process: arbiter.c (use macros), unif.c (scm_array_p),
2753 Wed Mar 8 10:15:59 2000 Greg J. Badros <gjb@cs.washington.edu>
2755 * numbers.c: Use SCM_VALIDATE_LONG_COPY, and longs, not ints, in
2756 various logXXX primitives. Thanks Eric Moore!
2758 Tue Mar 7 08:05:22 2000 Greg J. Badros <gjb@cs.washington.edu>
2760 * run-test, remaining-docs-needed: Added these scripts. The
2761 second one is only temporary until the docstring additions are
2762 complete. run-test may best live on, but is here mostly for
2763 convenience and awareness for now.
2765 * hash.c: Docs, minor cleanup patch from Dirk Herrman.
2767 Thu Mar 2 16:06:58 2000 Greg J. Badros <gjb@cs.washington.edu>
2769 * error.h, error.c: Added `scm_wrong_type_arg_msg' to support
2770 displaying the expected type. Use SCM_LISTn in a couple places
2771 instead of scm_cons-ing by hand.
2773 * __scm.h: Added SCM_ASSERT_TYPE macro.
2775 * validate.h, scm_validate.h: Added the former, as a renamed
2776 version of the latter with SCM_ASSERT_TYPE used in
2777 SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
2779 * Makefile.am: Rename scm_validate.h to validate.h.
2781 * *.c, *.h: Include validate.h, not scm_validate.h (old name's
2782 prefix was superfluous).
2784 Thu Mar 2 15:33:12 2000 Greg J. Badros <gjb@cs.washington.edu>
2786 * hashtab.c: Improved documentation for lots of functions. Added
2787 handwritten docs for `hash-fold'.
2789 Thu Mar 2 15:13:25 2000 Greg J. Badros <gjb@cs.washington.edu>
2791 * list.c: Added hand-written docs for `del{q,v,ete}1!'.
2793 Thu Mar 2 12:38:30 2000 Greg J. Badros <gjb@cs.washington.edu>
2795 * list.c: Moved append docs to append! Thanks Dirk Hermann. Also,
2796 added append docs from R4RS.
2798 * strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
2799 Thanks Dirk Hermann!
2801 * chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
2802 deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR. Thanks Dirk Hermann!
2804 * *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
2805 Drop use of SCM_P for function prototypes... assume an ANSI C
2806 compiler. Thanks Dirk Hermann!
2808 Sat Feb 19 12:20:12 2000 Greg J. Badros <gjb@cs.washington.edu>
2810 * ports.c: Made `set-port-column!' and `set-port-line!' each
2811 return SCM_UNSPECIFIED instead of a (not-scheme-object) integer
2812 that caused a seg fault. Also fixed `set-port-column!'s
2813 docstring. Thanks Han-Wen Nienhuys for finding the bug!
2815 Sun Feb 13 19:11:42 2000 Greg J. Badros <gjb@cs.washington.edu>
2817 * arbiters.c, eq.c, gc.c, guardians.c, list.c, ports.c, print.c,
2818 regex-posix.c, scmsigs.c, stime.c, strings.c, variable.c, stime.c,
2819 strings.c, variable.c: Added lots of documentation, cleaned up
2820 some existing documentation. Occasionally changed formal params
2821 to match docs. Also folded an #ifdef into the inners of a
2822 primitive instead of having two copies of the primitive
2823 (`get-internal-real-time', from stime.c)
2825 Sun Feb 13 18:12:19 2000 Greg J. Badros <gjb@cs.washington.edu>
2827 * ports.c: Added docs for primitives missing them. Written by
2830 Sun Feb 13 09:40:36 2000 Greg J. Badros <gjb@cs.washington.edu>
2832 * guile-doc-snarf.in: Use ${AWK} -f guile-func-name-check, not
2833 just execing guile-func-name-check. Thanks Michael Livshin!
2835 Thu Feb 10 11:43:23 2000 Greg J. Badros <gjb@cs.washington.edu>
2837 * guile-snarf.awk.in: Tweak to work with Sun/HP awk, removed some
2838 dead code. Patch from Michael Livshin.
2840 * guile-doc-snarf.in: Tweak to work with Sun/HP sh. Patch from
2843 2000-02-09 Gary Houston <ghouston@arglist.com>
2845 * init.c (scm_init_standard_ports): when stdout is a tty, make the
2846 current-output-port unbuffered by default. this is less confusing
2847 for interactive use. it was line-buffered because of a
2848 performance problem with unbuffered ports, but I think it will be
2851 2000-02-08 Gary Houston <ghouston@arglist.com>
2853 * __scm.h: don't define long_long or ulong_long if HAVE_LONG_LONGS
2856 * stime.c (scm_localtime, scm_mktime): if neither HAVE_TM_ZONE nor
2857 HAVE_TZNAME are defined, use an empty string instead of giving two
2858 spurious compile-time errors.
2860 Tue Feb 8 13:57:46 2000 Greg J. Badros <gjb@cs.washington.edu>
2862 * ports.c: Doc patches from Richard Kim. Pasted from MIT Scheme.
2865 Mon Feb 7 09:07:31 2000 Greg J. Badros <gjb@cs.washington.edu>
2867 * macros.c: Doc patches from Richard Kim. Pasted from scm.texi.
2869 Sun Feb 6 20:26:21 2000 Greg J. Badros <gjb@cs.washington.edu>
2871 * pairs.c: Doc patches from Richard Kim. Pasted from MIT Scheme
2872 (which is GNU GPL'd).
2874 2000-01-31 Gary Houston <ghouston@arglist.com>
2876 * strings.h: don't use SCM_P. don't include <string.h>.
2877 * error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>.
2879 * strings.c (scm_string_ref): make the 2nd argument compulsory.
2880 previously it defaulted to zero for no good reason that I can see.
2881 use a local variable for SCM_INUM (k). replace
2882 SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
2884 (scm_makfromstr): cosmetic changes.
2886 (scm_string): Accept only chars in the list, not strings, for
2887 conformance to R5RS (particularly for list->string, which is
2888 supposed to be the inverse of string->list.) remove
2889 SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
2890 scm_makstr handles the cell allocation. when reporting wrong-type
2891 arg, don't report the position as 1.
2893 * posix.c (scm_init_posix): intern PIPE_BUF if it's defined.
2895 2000-01-29 Gary Houston <ghouston@arglist.com>
2897 * posix.c (scm_pipe): rewrote the docstring.
2899 * filesys.c (scm_select, retrieve_select_type, get_element,
2900 fill_select_type, set_element): modified so that Scheme
2901 "select" tests port buffers for the ability to provide input
2902 or accept output. Previously only the underlying file descriptors
2903 were checked. Rewrote the docstring.
2905 Thu Jan 27 10:14:25 2000 Greg J. Badros <gjb@cs.washington.edu>
2907 * vectors.c, symbols.c, strorder.c: Documentation cut and pasted
2908 from Gregg Reynolds. Thanks Gregg!
2910 Thu Jan 27 09:59:38 2000 Greg J. Badros <gjb@cs.washington.edu>
2912 * strop.c (scm_i_index): Obfuscated commented-out SCM_DEFINE by
2913 adding "x" prefix to the line so that guile-func-name-check
2914 doesn't complain unnecessarily.
2916 Wed Jan 26 17:33:52 2000 Greg J. Badros <gjb@cs.washington.edu>
2918 * throw.c: Factor out an #ifdef/#else/#endif choice more finely
2919 for maintainability.
2921 * strop.c: Documentation added by Gregg A. Reynolds. Pasted in
2924 Wed Jan 26 10:02:11 2000 Greg J. Badros <gjb@cs.washington.edu>
2926 * tag.c: Added doc for `tag', but mark as deprecated since Mikael
2927 suggests removing tag.c altogether (and using a new `class-of'
2930 * strings.c: Added documentation from Gregg A. Reynolds. Edited
2931 a bit by me to use FOO instead of @var{foo} and to have the
2932 summary come before preconditions on input. Also dropped trailing
2935 * gsubr.c: Do not use SCM_DEFINE for `gsubr-apply'. Register the
2936 function with scm_make_subr_opt w/ last arg of 0 so it is not
2937 visible at the Scheme level. Mikael says that this is the right
2938 thing because the first arg to the proc is the guts of a compiled
2939 closure and shouldn't be exposed to the Scheme level.
2941 Tue Jan 25 17:15:47 2000 Greg J. Badros <gjb@cs.washington.edu>
2943 * sort.c: typo in comment fixed.
2945 * keywords.c: Added documentation.
2947 * guardians.c: Added documentation (could be better).
2949 * gc.c: Added docs for gc-set-debug-check-freelist.
2951 * eq.c: Added docs for eq?, eqv? equal? abridged from R4RS.
2953 * boolean.c: Added docs for `not', `boolean?' (by hand).
2955 Tue Jan 25 13:28:56 2000 Greg J. Badros <gjb@cs.washington.edu>
2957 * random.c: Added documentation, from SLIB page:
2958 http://angela.ctrl-c.liu.se/~calle/scheme/slib_toc.html
2960 Mon Jan 24 17:50:20 2000 Greg J. Badros <gjb@cs.washington.edu>
2962 * variable.c, version.c: Added documentation, written by hand
2963 since I could not find anything already written that was
2966 2000-01-23 Gary Houston <ghouston@arglist.com>
2968 * filesys.c (scm_chown): omit port/fdes support if HAVE_FCHOWN is
2969 not defined (thanks to Richard Y. Kim).
2971 Thu Jan 20 13:00:38 2000 Greg J. Badros <gjb@cs.washington.edu>
2973 * Makefile.in: Removed, this is auto-generated.
2975 Thu Jan 20 11:33:47 2000 Dirk Hermann <dirk@ida.ing.tu-bs.de> --applied 01/20/00 gjb
2977 * list.c: Put some variable initialization code at the point of
2978 declaration; Added a comment for list*; Formatting changes.
2980 * load.c: use SCM_NNULLP to make sure the end of a list is not
2983 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2985 * backtrace.c (scm_display_error_message): Bugfix: Don't use
2986 result of scm_list_p as C boolean.
2987 (scm_display_error_message, scm_set_print_params_x): Use new
2988 validation macros. (Thanks to Dirk Herrmann.)
2990 * net_db.c (scm_resolv_error): Cast result from hstrerror.
2992 * strports.c (st_end_input): Inserted parenthesis to get operator
2995 * list.h (scm_init_list): Removed SCM_P around prototypes.
2997 * fports.c, list.c, numbers.c, ports.c, stime.c, symbols.c,
2998 filesys.c, posix.c: Converted docstrings to ANSI C format and
2999 escaped " occurring inside string literals.
3001 Tue Jan 18 13:21:08 2000 Mikael Djurfeldt <mdj@r11n07-s.pdc.kth.se>
3003 * posix.c (scm_mknod): Escape " occuring inside docstring.
3005 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3007 * alist.c, chars.c, debug.c, dynl.c, dynwind.c, error.c, eval.c,
3008 evalext.c, filesys.c, gc.c, hash.c, hashtab.c, ioext.c,
3009 keywords.c, list.c, load.c, macros.c, net_db.c, numbers.c,

3013 symbols.c, throw.c, unif.c, vectors.c, version.c, vports.c,
3014 weaks.c: Converted docstrings to ANSI C format.
3016 * filesys.c (scm_chmod), simpos.c (scm_system), version
3017 (scm_version), vports (scm_make_soft_port): Escape " occuring
3020 Mon Jan 17 11:41:22 2000 Greg J. Badros <gjb@cs.washington.edu>
3022 * scm_validate.h: Added SCM_VALIDATE_ULONG_COPY,
3023 SCM_VALIDATE_LONG_COPY
3025 * numbers.c: Use SCM_VALIDATE_ULONG_COPY, instead of
3026 SCM_VALIDATE_INUM_COPY to let bigger numbers be used. Rename a
3027 couple of formal arguments (and fix their uses) to make arguments
3028 match the documentation.
3030 2000-01-14 <mstachow@alum.mit.edu>
3032 * Makefile.am: Augment path when running guile-doc-snarf so
3033 guile-func-name-check is found.
3035 Fri Jan 14 09:34:55 2000 Greg J. Badros <gjb@cs.washington.edu>
3037 * scm_validate.h (SCM_NUM2LONG_DEF): Fix this macro to just use
3038 def, not SCM_MAKINUM(def); thanks Janis Bzerins!
3040 Wed Jan 12 00:06:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3042 * net_db.c (s_scm_inet_makeaddr): Use SCM_NUM2ULONG since that's
3043 the way guile-1.3.4 worked, but #if 0 out the version using
3044 SCM_VALIDATE_INUM_COPY for stricter testing.
3046 Tue Jan 11 18:24:18 2000 Greg J. Badros <gjb@cs.washington.edu>
3048 * guile-doc-snarf.in: Use new $fullfilename for running
3049 guile-func-name-check, and put "$fullfilename" and "$filename" in
3050 quotes at uses to make sure re-splitting on whitespace does not
3051 occur (so filenames w/ embedded whitespace would work okay, though
3052 I sure hope we never have to deal with that! :-) ). Thanks to
3053 Mikael for pointing out the source_dir != build_dir was broken.
3055 Tue Jan 11 17:42:40 2000 Greg J. Badros <gjb@cs.washington.edu>
3057 * scm_validate.h: Added SCM_NUM2LONG_DEF macro. Make
3058 SCM_OUT_OF_RANGE use SCM_MAKINUM, not scm_long2num. Added
3059 SCM_COERCE_ROSTRING macro. Added SCM_VALIDATE_NONEMPTYLIST
3060 macro. Fix SCM_VALIDATE_STRINGORSUBSTR macro to not use SLOPPY
3063 * ports.c (scm_port_closed_p): Validate that the arg is a PORT,
3064 then return whether it's an open port (was validating that it was
3065 an open port -- this was a bug I introduced back in December, but
3066 my careful reading of diffs caught it).
3068 * numbers.c: Recombine the two conditional-compilation paths for
3069 all the log* primitives -- they were split based on #ifndef
3070 scm_long2num; factored out a SCM_LOGOP_RETURN macro, and fixed
3071 some bugs and inconsistencies in the two sets of implementations.
3072 (scm_lognot) Fixed *atrocious* re-use of a SCM as an integer!
3074 * ioext.c: Use SCM_ASSERT_RANGE in a couple places, and
3075 SCM_VALIDATE_INUM_COPY once where it should've been used.
3077 * fluids.c (scm_internal_with_fluids): Use
3078 SCM_VALIDATE_LIST_COPYLEN.
3080 * filesys.c: Use SCM_NUM2LONG instead of SCM_VALIDATE_INUM_COPY;
3081 this is questionable as it relaxes type safety, but other changes
3082 were useful and all SCM_NUM2LONG's should probably be
3083 revisited. Use SCM_OUT_OF_RANGE, SCM_WRONG_TYPE_ARG.
3085 * evalext.c: line-break change on 1 line.
3087 * eval.c (nconc2last): Takes a non-empty list as its first
3088 argument, not just a list.
3090 * dynl.c: Use new SCM_COERCE_ROSTRING macro.
3092 Tue Jan 11 15:44:23 2000 Greg J. Badros <gjb@cs.washington.edu>
3094 * dynl.c, feature.c, filesys.c, fports.c, list.c, load.c,
3095 net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
3098 * symbols.c (scm_sysintern0): Fixed the function name in a
3099 scm_misc_error invocation.
3101 * print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
3102 use scm_return_first to ward off latent GC bug that Mikael caught.
3104 * async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
3105 used before but should've been.
3107 2000-01-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3109 * snarf.h (SCM_PROC1): Replaced SCM (*) (...) with
3110 SCM_FUNC_CAST_ARBITRARY_ARGS.
3112 Tue Jan 11 13:44:07 2000 Greg J. Badros <gjb@cs.washington.edu>
3114 * guile-func-name-check.in: Added this script to statically check
3115 #define FUNC_NAME, #undef FUNC_NAME in the source.
3117 * sort.c, posix.c: Fix #undef FUNC_NAME lines to not have trailing
3118 redundant comment, semicolon; caught by new guile-func-name-check
3121 * debug.c: Fix mistaken #define FUNC_NAME for scm_make_iloc.
3122 Caught by new guile-func-name-check-script.
3124 * Makefile.am: Added guile-func-name-check to bin_SCRIPTS
3126 * ramap.c: Fix #if 0'd out code to be syntactically acceptable to
3127 guile-func-name-check.
3129 * guile-doc-snarf.in: Run guile-func-name-check on the file before
3132 Tue Jan 11 11:31:10 2000 Greg J. Badros <gjb@cs.washington.edu>
3134 * fports.c, ports.c, ports.h, strports.c, vports.c: Make write
3135 port function take const void*, not void*.
3137 Tue Jan 11 11:18:07 2000 Greg J. Badros <gjb@cs.washington.edu>
3139 * scm_validate.h, chars.c, ports.c, print.c, read.c, strings.c,
3140 strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
3141 SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY. Change made for
3142 consistency with the other macros dealing with immediate
3143 characters. (Similar to INT -> INUM change a week or so ago).
3145 Tue Jan 11 10:41:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3147 * dynl.c, error.c, eval.c, feature.c, filesys.c, fports.c, list.c, load.c,
3148 net_db.c, read.c, socket.c: Update error messages to use ~A for
3149 %s, ~S for %S to work with new `simple-format' format and be
3150 standardized better.
3152 * print.h, print.c (scm_simple_format): Added `simple-format'
3153 primitive. It's the old scm_display_error, with ARGS now a rest
3154 parameter, and the destination first instead of last (and a couple
3155 new capabilities inspired by `format' -- #t as destination means
3156 current-output-port, #f means return the formatted text as a
3159 * gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
3161 * backtrace.c (scm_display_error_message): Rewrote to use
3162 scm_simple_format() procedure.
3164 * __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
3166 2000-01-09 Marius Vollmer <mvo@zagadka.ping.de>
3168 Finally applied the libltdl patch from Thomas Tanner, with slight
3171 * DYNAMIC-LINKING: Removed because it is obsolete.
3172 * dynl.c: Use ANSI prototypes.
3173 (sysdep_dynl_link): Use lt_dlopenext instead of lt_dlopen.
3174 * scmconfig.h.in: Do not change, as it is automatically generated.
3176 1999-07-25 Thomas Tanner <tanner@ffii.org>
3178 * dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c: deleted
3180 * Makefile.am: likewise, add INCLTDL (libltdl headers) to
3181 INCLUDES, set dlpreopened files in LDFLAGS, link libguile
3183 * dynl.c: use libltdl if DYNAMIC_LINKING is enabled,
3184 * guile.c: register preloaded modules
3185 * scmconfig.h.in: remove obsolete symbols
3187 2000-01-09 Gary Houston <ghouston@arglist.com>
3189 * These changes should make it unnecessary to call tzset from
3190 Scheme after modifying the TZ environment variable, even if the
3191 system date facilities cache the value.
3192 * stime.c (setzone, scm_localtime): added comments.
3193 (tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
3194 (setzone): don't call tzset.
3195 (restorezone): call tzset only if HAVE_TZSET is defined.
3196 (scm_tzset): don't define if HAVE_TZSET not defined. Change the
3197 doc string to indicate that this procedure isn't likely to do
3199 (scm_localtime, scm_strftime, scm_mktime): call tzset if
3200 LOCALTIME_CACHE is defined.
3202 2000-01-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3204 * posix.c (scm_sync): Return SCM_UNSPECIFIED.
3206 2000-01-09 Gary Houston <ghouston@arglist.com>
3208 * eval.c: define scm_unbound_variable_key ('unbound-variable).
3209 scm_lookupcar1: throw an error with key 'unbound-variable instead
3210 of 'misc-error when an unbound variable is encountered.
3212 * filesys.c (scm_mkdir, scm_rmdir, scm_getcwd, scm_select,
3213 scm_symlink, scm_readlink, scm_lstat),
3214 posix.c (scm_setpgid, scm_setsid, scm_ctermid, scm_tcgetpgrp,
3215 scm_tcsetpgrp, scm_uname, scm_setlocale, scm_mknod, scm_nice,
3217 simpos.c (scm_system),
3218 stime.c (scm_times, scm_strptime):
3219 move the HAVE_XXX feature tests out of the procedure bodies.
3220 don't use SCM_SYSMISSING.
3221 scm_validate.h (SCM_SYSMISSING): removed.
3222 error.h, error.c (scm_sysmissing): comment that this is deprecated.
3223 see ChangeLog entry for 1999-12-28.
3225 Sat Jan 8 19:52:04 2000 Greg J. Badros <gjb@cs.washington.edu>
3227 * scm_validate.h (SCM_VALIDATE_BOOL_COPY): Fix typo.
3229 Sat Jan 8 17:06:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3231 * backtrace.c: Fix spelling typo in a comment.
3233 * snarf.h: Use new SCM_DOCS macro to encapsulate the non SCM_INIT
3234 text. Reformatted some of the expansions.
3236 Fri Jan 7 15:50:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3238 * scm_validate.h (SCM_OUT_OF_RANGE): Use scm_out_of_range_pos to
3239 report the position of the argument.
3241 * error.h, error.c (scm_out_of_range_pos): Added this function to
3242 take extra "pos" argument, the position number of the errant
3245 * debug.c: Use SCM_OUT_OF_RANGE instead of scm_out_of_range.
3247 * snarf.h: Use SCM_HERE and SCM_INIT as names, not SCM_NOTSNARF
3248 and SCM_SNARFING. Also put the %%% in the SCM_INIT since Mikael
3249 prefers that and I'm reasonably indifferent.
3251 Fri Jan 7 15:03:32 2000 Greg J. Badros <gjb@cs.washington.edu>
3253 * snarf.h: Factor out differences between C++ and non-C++ into
3254 SCM_FUNC_CAST_ARBITRARY_ARGS macro. Modify all the snarf macro
3255 definitions to use SCM_NOTSNARF and SCM_SNARFING macros (like
3256 Mikael's macros, below, but changed names and SCM_SNARFING no
3257 longer expands to include %%% -- that must appear in the argument
3258 so that the token appears at the call-site as a reminder).
3260 2000-01-07 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3262 * snarf.h (SCM_INSITU, SCM_INIT): New snarf macros for use in user
3263 snarf macro definitions.
3265 2000-01-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3267 * chars.c (scm_integer_to_char): Use Greg's nice
3268 SCM_VALIDATE_INUM_RANGE macro for argument checking for closer
3271 Thu Jan 6 11:48:49 2000 Greg J. Badros <gjb@cs.washington.edu>
3273 * *.c, snarf.h: Replace GUILE_PROC1 with SCM_DEFINE1 throughout.
3275 Thu Jan 6 11:22:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3277 * Makefile.am (ETAGS_ARGS): Switch to SCM_DEFINE, SCM_DEFINE1
3278 instead of GUILE_PROC.
3280 Thu Jan 6 11:21:49 2000 Greg J. Badros <gjb@cs.washington.edu>
3282 * alist.c: Do not report mismatch errors on some uses of `tmp' (do
3283 this by using SCM_ARG2 instead of `2' in the SCM_VALIDATE_CONS
3286 Thu Jan 6 09:54:33 2000 Dirk Herrmann <dirk@ida.ing.tu-bs.de> --gjb applied
3288 * scm_validate.h: Remove some redundant NIMP tests.
3290 * alist.c: minimize scope of the tmp variables, and initialize
3291 them when declared. The strange SCM_NIMP tests are replaced by
3292 SCM_CONSP tests that more closely reflect the intended semantics.
3293 However, we don't get a performance penalty here, because the
3294 SCM_CONSP test was performed by the ALISTCELL test anyway. * The
3295 extremely ugly use of ASRTGO macros was removed: The calls to
3296 ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a
3297 label parameter that only exists when SCM_RECKLESS is not defined.
3298 This works, because ASRTGO itself is defined in a way that it only
3299 makes use of the label parameter if SCM_RECKLESS is not defined
3300 (shudder!). Does guile make at all use of the possibility to
3301 define SCM_RECKLESS? * Codesize is likely to be reduced, since
3302 instead of two calls to SCM_ASSERT performed by the ALISTCELL test
3303 we now only get one test.
3305 * list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate. Also use
3306 SCM_NULLP instead of SCM_IMP. Drop use of "register" keyword on
3307 some variables in `list?'. Fix `reverse' and `reverse!'
3308 primitives to handle improper lists better.
3310 Wed Jan 5 11:24:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3312 * *.[ch]: Whitespace changes -- added space after SCM_VALIDATE_*
3313 macros and SCM_DEFINE macros to match GNU coding standards.
3315 Wed Jan 5 11:04:24 2000 Greg J. Badros <gjb@cs.washington.edu>
3317 * *.[ch]: Replace GUILE_PROC w/ SCM_DEFINE.
3319 Wed Jan 5 10:59:06 2000 Greg J. Badros <gjb@cs.washington.edu>
3321 * *.[ch]: Replace SCM_VALIDATE_INT w/ SCM_VALIDATE_INUM for
3322 better consistency with the names of other SCM_VALIDATE_ macros
3323 and better conformance to guile naming policy.
3325 Wed Jan 5 10:50:39 2000 Greg J. Badros <gjb@cs.washington.edu>
3327 * ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a
3328 SCM_VALIDATE instead of 1 to avoid a check on the argument (since
3329 it's not the actual name of the formal).
3331 * guile-snarf.awk.in: Do argument/number mismatch checking and
3332 print warnings in an Emacs compile-mode parseable format.
3334 * struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/
3335 SCM_OUTOFRANGE as 3rd argument.
3337 * random.c: Fix argument/number mismatch (that I introduced :-( ).
3339 * __scm.h: Do not #define SCM_ARG* when snarfing;
3340 lets us distinguish between 1 and SCM_ARG1 when snarfing as only
3341 the former (using the number) requires the argument to match the
3342 formal in the current argument snarfing check.
3344 * snarf.h: Give new definition of SCM_ASSERT when in
3345 snarfing mode to output a lexically-identifiable sequence that the
3346 guile-snarf.awk script uses to verify argument/position matching.
3348 * ramap.c: Remove extraneous #undef FUNC_NAME.
3350 Wed Jan 5 08:36:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3352 * guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the
3353 current version of the same functionality; it writes the .x output
3354 to stdout instead of directly into the file.
3356 Wed Jan 5 08:15:04 2000 Greg J. Badros <gjb@cs.washington.edu>
3358 * unif.c, symbols.c, strings.c, stacks.c, random.c, print.c,
3359 posix.c: Eliminated a bunch of SCM_NIMP(..)s that are now
3360 redundant with the safer macros. Patch from Dirk Hermann applied
3361 by hand. Thanks Dirk!
3363 * scm_validate.h: Added SCM_VALIDATE_VECTOR_OR_DVECTOR for some
3366 * ramap.c: whitespace change.
3368 Tue Jan 4 14:21:35 2000 Greg J. Badros <gjb@cs.washington.edu>
3370 * options.c, objects.c, keywords.c, gc.c: Some redundant SCM_NIMP
3371 removals from Dirk Hermann.
3373 * alist.c: Rename formals to match the parameter names in the
3374 documentation, updates to documentation. Thanks Dirk Hermann!
3376 2000-01-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3378 * eval.c (SCM_CEVAL): Reverse order of
3379 scm_stack_checking_enabled_p and SCM_STACK_OVERFLOW_P
3380 (Thanks to Brad Knotwell.)
3382 Mon Jan 3 08:30:02 2000 Greg Harvey <Greg.Harvey@thezone.net> (applied --01/03/00 gjb)
3384 * gc.c (scm_debug_newcell): Added SCM_SETCAR of the newly
3387 * pairs.h: Added a comment about the need for the SCM_SETCAR in
3390 Mon Jan 3 08:25:19 2000 Greg J. Badros <gjb@cs.washington.edu>
3392 * dynl-vms.c, debug.c, coop-threads.c, backtrace.c, eval.c: More
3393 SCM_NIMP tests that were redundant are now eliminated. Patches
3394 from Dirk Hermann applied by hand.
