58 scm_dynamic_link, scm_init_dynamic_linking), dynl.h
59 (scm_dynamic_link): Removed possibility to pass flags to
60 scm_dynamic_link, as it had no effect anyway.
62 * filesys.c (scm_fcntl): Made single optional rest argument into
63 a standard optional argument.
65 * hooks.c (scm_run_hook): A list of rest arguments is never
68 * list.c (scm_append, scm_append_x), stacks.c (scm_make_stack),
69 strings.c (scm_string_append): Don't perform half-hearted checks
70 to see whether the rest argument forms a proper list any more, use

80 (ss_handler, handler_message): Make first mandatory rest argument
81 of scm_make_stack into a standard mandatory argument.
83 * unif.c (scm_transpose_array, scm_enclose_array,
84 scm_array_in_bounds_p), unif.h (scm_transpose_array,
85 scm_enclose_array, scm_array_in_bounds_p): Make first mandatory
86 rest argument into a standard mandatory argument.
88 2000-05-17 Dirk Herrmann <D.Herrmann@tu-bs.de>

110 SCM_INUM): Removed conditionally compiled code for Turbo C.
112 * gdbint.c (gdb_maybe_valid_type_p): Eliminated call to scm_tag.
113 That check can be assumed to be redundant except for very rare
114 conditions that actually indicate broken heap data.
116 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
118 * numbers.c (scm_logcount, scm_integer_length): Reordered
121 2000-05-15 Gary Houston <ghouston@arglist.com>
123 * stime.c (scm_strftime): don't reset TZ if zone is an empty

143 (scm_tc16_flo, scm_tc_flo, scm_tc_dblr, scm_tc_dblc): Wrapped
144 deprecated code between #if (SCM_DEBUG_DEPRECATED == 0) #endif.
146 * fports.c (scm_fport_buffer_add), ports.c (scm_input_port_p,
147 scm_output_port_p), print.c (scm_get_print_state), validate.h
148 (SCM_VALIDATE_CHAR): Replace use of deprecated macros
149 SCM_INPORTP, SCM_OUTPORTP, SCM_ICHRP by SCM_INPUT_PORT_P,
150 SCM_OUTPUT_PORT_P, SCM_CHARP, respectively.
152 2000-05-14 Gary Houston <ghouston@arglist.com>
154 * stime.c (scm_strftime): if HAVE_TM_ZONE is not defined, hack the
155 TZ environment variable so that the %Z format returns the zone
156 from the input vector instead of the system default.
158 from Keisuke Nishida:
159 * fports.c (scm_setvbuf): minor docstring fix.
160 * ports.h (scm_generic_fgets): obsolete prototype deleted.
162 2000-05-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
164 * __scm.h: Added new section for debugging options.
166 (SCM_DEBUG_DEPRECATED): If 1, no deprecated code is included to
167 help developers to get rid of references to deprecated code.
169 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_UNEGFIXABLE,
170 SCM_FIXABLE, SCM_FLOBUFLEN): These macros are no longer provided
171 as part of the interface and are marked as deprecated in the
174 * numbers.c (scm_make_real, scm_make_complex): Inlined the
175 corresponding macros SCM_NEWREAL and SCM_NEWCOMPLEX,
178 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX, SCM_INEXP, SCM_CPLXP,
179 SCM_REAL, SCM_IMAG, SCM_REALPART, scm_makdbl, SCM_SINGP,
180 SCM_NO_BIGDIG, SCM_NUM2DBL, scm_dblproc): Deprecated.
182 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
184 * gc.h (scm_cell, SCM_CELL_WORD, SCM_CELL_OBJECT,
185 SCM_SET_CELL_WORD, SCM_SET_CELL_OBJECT): Scheme cells now consist
186 of two scm_bits_t values instead of two SCM values, because it is
187 legal for cell entries to hold values that are not scheme objects.
189 (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR):
190 Use SCM_SETC[AD]R to modify contents of pairs.
192 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
194 * numbers.c (IS_INF, isfinite): Added FIXME comment.
196 (scm_abs, scm_magnitude): Make these two independent of each
197 other. scm_abs now reports an error if given a complex argument.
199 (scm_istr2flo, scm_integer_p). Use SCM_REAL_VALUE instead of
200 SCM_REALPART if the object is known to be real.
202 (scm_init_numbers): No need to use SCM_NEWREAL macro for speed
205 * numbers.h (SCM_SINGP): Set to 0 instead of SCM_BOOL_F.
207 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>

213 gh_scm2doubles), hash.c (scm_hasher), ramap.c (scm_array_fill_int,
214 ramap_rp, scm_array_map_x), random.c (vector_scale,
215 vector_sum_squares), unif.c (scm_make_uve, scm_array_p,
216 scm_array_set_x): Use SCM_REAL_VALUE instead of SCM_REALPART if
217 the object is known to be real. Use SCM_COMPLEXP instead of
218 deprecated SCM_CPLXP. Use SCM_INEXACTP instead of deprecated
221 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
223 * numbers.c: No need to include unif.h.
225 (IS_INF): Returned to old test for now: x == x + 1 will not work
226 for large numbers due to rounding errors.
227 Thanks to Kalle Olavi Niemitalo.
229 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
231 * numbers.c (scm_divbigdig): Removed outdated comment.

240 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
242 * numbers.c (IS_INF): The new test is x == x + 1. The old test
243 x == x/2 did not work for zero values. Thanks to Han-Wen Nienhuys
246 (scm_number_to_string, scm_sum, scm_difference, scm_two_doubles,
247 scm_num2long, scm_num2long_long, scm_num2ulong): Reordered
250 2000-05-09 Marius Vollmer <mvo@zagadka.ping.de>
252 * scmsigs.c (take_signal): Execute SCM_ASYNC_TICK for SIGSEGV,
253 SIGILL and SIGBUS signals. These signals are not continuable and
254 must be handled for real right away.
256 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
258 * numbers.c (scm_zero_p, scm_positive_p, scm_negative_p,
259 scm_real_part, scm_imag_part, scm_magnitude,
260 scm_inexact_to_exact): Reordered dispatch sequence.
262 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
264 * feature.c: No need to include "libguile/smob.h"
266 (scm_loc_features, features, scm_add_feature, scm_init_feature):
267 Removed variable 'scm_loc_features' as a pointer to the SCM value
268 holding the features list. Using variable 'features' instead,
269 which holds the interned pair. Thus, SCM_SETCDR can be used
270 instead of pointer trickery.
272 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
274 * alist.c (scm_acons): Use SCM{_SET}?_CELL_OBJECT as long as a
275 cell is not known to be a valid pair.
277 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
279 * eval.c (ASRTSYNTAX, scm_m_body, scm_m_letrec1): Removed
280 ASRTSYNTAX. Using SCM_ASSYNT instead.
282 (scm_m_body): Don't create a redundant cons cell.

289 redundant calculation of size, minimized some variable scopes.
291 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
293 * pairs.c (scm_cons, scm_cons2): Use SCM{_SET}?_CELL_OBJECT as
294 long as a cell is not known to be a valid pair.
296 (scm_pair_p): Eliminated redundant SCM_IMP test.
298 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
300 * eval.c (scm_m_body, scm_macroexp, unmemocopy, scm_eval_args,
301 scm_deval_args): Eliminated redundant SCM_IMP tests.
303 * hashtab.c (scm_ihashx, scm_sloppy_assx, scm_delx_x), weaks.c
304 (scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
305 scm_make_doubly_weak_hash_table): Fixed critical sections.
306 Thanks to Keisuke Nishida.
308 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
310 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest):
311 Fixed some goto-related initialization bugs (introduced by me).
313 2000-05-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
315 * numbers.h (SCM_INUM0): Uses SCM_MAKINUM instead of SCM_PACK.
317 * dynl.c (dynl_obj, DYNL_OBJ, get_dynl_obj): Removed.
319 (DYNL_FILENAME, DYNL_HANDLE): Use SCM_CELL... macros instead of
322 (SET_DYNL_HANDLE): Added.
324 (scm_dynamic_object_p): Simplified.
326 (scm_dynamic_unlink, scm_dynamic_func): Changed comment. Deliver
327 better error message when accessing unlinked dynamic objects.
328 Eliminated call to get_dynl_obj.
330 2000-05-03 Marius Vollmer <mvo@zagadka.ping.de>
332 * scmsigs.c (orig_handlers) [!HAVE_SIGACTION]: Fix declaration to
333 be an array of function pointers instead of being a pointer to an
334 array returning function. Thanks to Kalle Olavi Niemitalo!
336 2000-05-03 Dirk Herrmann <D.Herrmann@tu-bs.de>
338 * numbers.c (scm_divbigbig, scm_divbigint), numbers.h
339 (scm_divbigbig, scm_divbigint): Don't return zero any more to
340 indicate that a division has a remainder, return SCM_UNDEFINED
341 instead. It is improbable that anyone actually used these
342 functions outside of numbers.c. For this reason and due to the
343 change in behaviour the functions are static now. Thus, if
344 surprisingly there are users of these functions they will at least
347 * numbers.c: Removed #ifdef SCM_BIGDIG #endif in those functions,
348 that already have a clean dispatch order. Note: SCM_BIGDIG is
351 * numbers.c (scm_inexact_p): Simplified.
353 * numbers.c (scm_num_eq_p, scm_less_p, scm_max, scm_min,
354 scm_product, scm_num2dbl, scm_angle): Reordered dispatch
355 sequence, thereby fixing some comparisons of SCM values with
358 * numbers.c (scm_divide): Division by zero of inums leads to an
359 error now. (Formerly, an infinite number was returned.)
361 Respect the fact, that scm_divbigbig does now return SCM_UNDEFINED
362 if a division has a remainder.
364 2000-05-02 Gary Houston <ghouston@arglist.com>
366 * Makefile.am (INCLUDES): add ${INCLTDL} (thanks to Tim Mooney).
368 2000-05-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
370 * numbers.c (scm_logtest, scm_division): Reordered dispatch
371 sequence, thereby fixing some comparisons of SCM values with
374 * numbers.h (scm_makdbl): Mark as deprecated at the point of
377 * eval.c (SCM_CEVAL, SCM_APPLY), gh_data.c (gh_double2scm,
378 gh_doubles2scm), numbers.c (scm_istr2flo, scm_max, scm_min,

381 scm_real_part, scm_imag_part, scm_magnitude, scm_angle,
382 scm_long2num, scm_long_long2num, scm_ulong2num), ramap.c
383 (ramap_rp, scm_array_map_x), random.c (scm_random,
384 scm_random_uniform, scm_random_normal_vector_x, scm_random_exp),
385 struct.c (scm_struct_ref), unif.c (scm_array_to_list): Replace
386 call to scm_makdbl with a call to scm_make_real or
387 scm_make_complex, depending on whether the imaginary part is known
390 2000-05-01 Gary Houston <ghouston@arglist.com>
392 * scmsigs.c: fix the definition of orig_handlers for the case
393 that HAVE_SIGACTION is not defined (thanks to
394 Kalle Olavi Niemitalo).
396 * Makefile.am: remove include_HEADERS (was libguile.h)
397 libguile.h: moved to top level directory.
399 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
401 * numbers.c (SCM_SWAP): Moved to the top of the file to allow for
404 * numbers.c (scm_modulo, scm_gcd, scm_lcm, scm_logand, scm_logior,
405 scm_logxor): Reordered dispatch sequence, thereby fixing some
406 comparisons of SCM values with integer constants.
408 * number.c (scm_logtest): Removed some redundant SCM_{N}?IMP

413 * numbers.c (scm_quotient, scm_remainder): Removed code that was
414 conditionally compiled based on BADIVSGNS. BADIVSGNS does not
415 occur anywhere else throughout guile.
417 * numbers.c (scm_quotient): Fixed parameter number in error
420 * numbers.c (scm_remainder): Reordered dispatch sequence.
422 2000-04-25 Gary Houston <ghouston@arglist.com>
424 * posix.c (scm_execlp): docstring fix (thanks to Martin
427 2000-04-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
429 * eval.c (undef_object): Made into a local static variable
430 (suggested by Jost Boekemeier).
432 2000-04-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
434 * pairs.c (cxrs, scm_init_pairs): Simplify initialization of
437 * procs.c (scm_init_iprocs), procs.h (scm_subr, scm_iproc,
438 scm_dsubr, scm_init_iprocs): Removed.
440 * procs.h (SCM_SUBRF, SCM_DSUBRF): Access the cell words
441 directly instead of casting a cell to a C struct.
443 2000-04-22 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
445 Better modularization of GC extensions through new C level GC
448 * weaks.c (scm_weaks_prehistory): New function: Add
449 scm_weak_vector_gc_init to scm_before_mark_c_hook; Add

473 scm_after_gc_c_hook): New C level hooks.
474 (scm_after_gc_hook): New Scheme level hook.
475 (scm_gc_sweep): Moved scanning of weak vectors to weaks.c.
476 (scm_igc): Moved initialization of scm_weak_vectors and the call
477 to scm_guardian_gc_init to respective module.
478 (scm_mark_weak_vector_spines): Moved to weaks.c;
479 Call to scm_guardian_zombify moved to guardians.c;

502 Removed all -I options except for the root source directory and
503 the root build directory.
505 * numbers.c (scm_odd_p, scm_even_p): Use SCM_WRONG_TYPE_ARG
506 instead of SCM_ASSERT (0, ...). (Some compilers will complain
507 about control reaching end of function otherwise, and, besides,
508 the new code is not less clear.)
510 * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Added
511 calls to malloc debugging functions.
513 * init.c (scm_boot_guile_1): Added calls to debug-malloc init

527 scm_quotient): Reordered dispatch sequence to first handle
528 immediates, second handle bignums and finally handle generic
529 functions respectively signal wrong type arguments. Hopefully
530 this will allow for easier separation when goops is integrated.
532 2000-04-19 Dirk Herrmann <D.Herrmann@tu-bs.de>

1038 (mother): New function.
1039 (coop_create): New thread spawning mechanism which uses a "mother
1040 thread". The "dummy" pthreads aren't healthy enough to give birth
1041 to new threads since Linux threads thinks they are asleep.
1043 * coop-defs.h (struct coop_t): Removed dummy_mutex.
1045 * coop-defs.h, coop-threads.c (struct coop_t): Eliminate
1046 `sto'-field when GUILE_PTHREAD_COMPAT is enabled.
1048 2000-03-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
1050 * arbiters.c (scm_make_arbiter), async.c (scm_async), dynwind.c
1051 (scm_internal_dynamic_wind): Smob data is always of type
1054 * arbiters.c (SCM_ARB_LOCKED, SCM_LOCK_ARB, SCM_UNLOCK_ARB):
1055 Access the locking information in cell entry 0 with
1056 SCM_{SET_}?CELL_WORD_0 instead of SCM_*CAR.
1058 * async.c (scm_run_asyncs): Use SCM_NULLP to test for the empty
1061 * dynwind.c (scm_dowinds): Use SCM_EQ_P to compare SCM values.
1063 * ports.h (SCM_PTAB_ENTRY, SCM_SETPTAB_ENTRY): Access the ptab
1064 entry data using SCM_{SET_}?CELL_WORD_1 instead of SCM_{SET}?CDR.
1066 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1068 * alist.c (scm_sloppy_assq, scm_assq), eq.c (scm_eq_p, scm_eqv_p,
1069 scm_equal_p), list.c (scm_ilength, scm_last_pair, scm_reverse,
1070 scm_sloppy_memq, scm_delq_x, scm_delq1_x), tags.h (SCM_UNBNDP):
1071 Don't use C operators == and != to compare SCM values, use
1074 * boolean.c (scm_boolean_p): Use SCM_BOOLP to determine whether a
1075 SCM value is equal to #t or #f.
1077 * eq.c (scm_eqv_p, scm_equal_p): Don't use SCM_CAR to access the
1078 cell type entry of non immediate objects of unknown type. Use
1079 SCM_CELL_TYPE instead.
1081 * gh_data.c (gh_scm2bool, gh_module_lookup), list.c
1082 (scm_sloppy_memv, scm_sloppy_member, scm_delv_x, scm_delete_x,
1083 scm_delv1_x, scm_delete1_x), scmsigs.c (scm_sigaction): Use
1084 SCM_FALSEP and SCM_TRUE_P to compare SCM values against #f and
1087 * list.c (scm_listify): Use SCM_UNBNDP to test for an unbound
1090 2000-03-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1092 * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread,
1093 scm_make_mutex, scm_make_condition_variable): Cast data to
1094 scm_bits_t in SCM_SET_CELL_WORD and SCM_NEWSMOB macros.
1096 * coop.c (coop_create): Set `specific' field, not `data' to NULL.
1098 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1100 * smob.h (SCM_NEWSMOB, SCM_NEWSMOB2, SCM_NEWSMOB3, SCM_SMOB_DATA,
1101 SCM_SET_SMOB_DATA, SCM_TC2SMOBNUM, SCM_SMOBNUM): To access smob
1102 data, use SCM_{SET_}?CELL_TYPE or SCM_{SET_}?WORD_[1-3].
1104 Note that this implies that smob data has always to be passed as
1105 values of type scm_bits_t.
1107 2000-03-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1109 * threads.c (scm_init_threads): Pass 0 size to scm_make_smob_type
1110 for scm_tc16_thread. As the current COOP threads are written, GC
1111 is not supposed to manage storage for threads.
1113 * error.c (scm_error): Don't try to throw an error if
1114 scm_gc_heap_lock is true.
1116 * coop.c (coop_finish): New function. Called at exit.
1117 (coop_aborthelp): Free thread structures when threads die.
1118 Finished LinuxThreads compatibility support => COOP threads now
1119 mesh with LinuxThreads.
1121 * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread):
1122 Changed SETCDR --> SET_CELL_WORD_1.
1124 * coop-threads.c (scheme_launch_thread): Set word 1 of handle to 0
1127 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1129 * boolean.h (SCM_TRUE_P): New macro.
1131 * boolean.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOLP), pairs.h
1132 (SCM_NULLP, SCM_NNULLP): Use SCM_EQ_P to compare SCM values.
1134 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1136 * continuations.h (SCM_CONTREGS, SCM_SET_CONTREGS): New macros to
1137 access continuation data.
1139 (SCM_SETJMPBUF): Deprecated. Use SCM_SET_CONTREGS instead.
1141 (SCM_JMPBUF, SCM_DYNENV, SCM_THROW_VALUE, SCM_BASE, SCM_SEQ,
1142 SCM_DFRAME): Use SCM_CONTREGS instead of SCM_CHARS to access
1145 * continuations.c (scm_make_cont), init.c (start_stack),
1146 root.c (scm_internal_cwdr): Use SCM_SET_CONTREGS instead of
1149 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1151 * symbols.h (SCM_LENGTH, SCM_SETLENGTH): Access the length field
1152 of strings and symbols by using SCM_{SET_}?CELL_WORD_0.
1154 (SCM_CHARS, SCM_UCHARS, SCM_SETCHARS): Use SCM_{SET_}?CELL_WORD_1
1155 to access the char * field of strings and symbols.
1157 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
1159 * gc.h (SCM_NEWCELL, SCM_NEWCELL2): Use SCM_SET_CELL_TYPE to set
1160 the type entry of a new cell. Added a comment about things to
1161 remember when updating the list of free cells.
1163 (SCM_FREEP, SCM_MARKEDP): Use SCM_CELL_TYPE to access the type
1166 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
1168 * pairs.h (SCM_CAR, SCM_CDR, SCM_SETCAR, SCM_SETCDR): Use
1169 SCM_CELL_OBJECT and SCM_SET_CELL_OBJECT. This change implies that
1170 with strict type checking enabled these macros will only work if
1171 given valid SCM parameters.
1173 (SCM_GCCDR): Moved to tags.h.
1175 * tags.h (SCM_GCCDR): Moved here from pairs.h.
1177 2000-03-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
1179 * tags.h (SCM2PTR, PTR2SCM): Moved to gc.h.
1181 * pairs.h (scm_cell, SCM_CELLPTR, SCM_CELL_WORD*, SCM_CELL_OBJECT*,
1182 SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*, SCM_CELL_TYPE,
1183 SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK, SCM_PTR_GT,
1184 SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC, SCM_NEWCELL,
1185 SCM_NEWCELL2): Moved to gc.h.
1187 (SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR, SCM_SETAND_CDR,
1188 SCM_SETOR_CAR, SCM_SETOR_CDR): Moved to gc.h. These names should
1189 be changed, though, since the macros are not only pair related.
1193 * gc.h (SCM2PTR, PTR2SCM, scm_cell, SCM_CELLPTR, SCM_CELL_WORD*,
1194 SCM_CELL_OBJECT*, SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*,
1195 SCM_CELL_TYPE, SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK,
1196 SCM_PTR_GT, SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC,
1197 SCM_NEWCELL, SCM_NEWCELL2, SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR,
1198 SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR): Moved here from
1201 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1203 * tags.h (SCM_STRICT_TYPING): New macro that, if defined,
1204 activates strict compile time type checking for variables of
1206 (SCM, SCM_PACK, SCM_UNPACK): Define according to whether
1207 SCM_STRICT_TYPING or SCM_VOIDP_TEST are defined.
1208 (SCM_EQ_P): Defined as a macro equivalent for eq?.
1210 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1212 * tags.h (SCM_POINTERS_MUNGED): Removed.
1214 * gc.c (scm_gc_sweep, init_heap_seg): Removed use of
1215 SCM_POINTERS_MUNGED, thus fixing some illegal casts to SCM.
1217 2000-03-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
1219 * pairs.h (SCM_CELL_OBJECT, SCM_CELL_OBJECT_[0-3],
1220 SCM_SET_CELL_OBJECT, SCM_SET_CELL_OBJECT_[0-3], SCM_CELL_TYPE,
1221 SCM_SET_CELL_TYPE): Added a set of low level macros for accessing
1223 (SCM_CELL_WORD_[0-3]): Renamed from the SCM_CELL_WORD[0-3].
1225 * procs.h, procs.c: Instead of SCM_{SET_}?CELL_WORD[12], use the
1226 newly introduced SCM_{SET_}?CELL_OBJECT_[12] macros.
1228 2000-03-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1230 * tags.h: Disabled definition of SCM_VOIDP_TEST.
1232 Defining SCM as void * introduces problems which haven't been
1233 handled yet. Developers who work with these issues can enable it
1234 in their working copies.
1236 Disabling this definition exposes a set of newly introduced and
1237 older misuses of types which causes warning messages during
1238 compilation. We'll fix this successively.
1240 * gc.c (scm_mark_locations): Changed * (SCM **) X --> * (SCM *) X
1241 in order to obtain a value of type SCM.
1242 (scm_cellp): Updated with new changes to scm_mark_locations.
1244 * continuations.h (SCM_SETJMPBUF): Cast second arg into SCM.
1246 * continuations.c (scm_make_cont): Removed cast of size_t into
1249 * symbols.h (SCM_SETCHARS): Cast second arg into SCM.
1251 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
1253 * numbers.h (SCM_SETNUMDIGS): Use SCM_BIGSIZEFIELD macro for
1254 shifting, not constant. Thanks to Dale P. Smith.
1256 * numbers.c (scm_sum, scm_difference): Don't test a SCM value
1257 for being less than zero. Decode it to a C value first. Again,
1260 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
1262 * numbers.h, ramap.c, struct.h, vectors.h: Don't use SCM2PTR for
1263 non scheme values. If raw data is stored in SCM variables, it has
1264 to be accessed using SCM_UNPACK until a better solution is found.
1266 2000-03-22 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1268 * tags.h (SCM_ECONSP, SCM_NECONSP): More corrections of
1269 pointer-arithmetic induced by the SCM_PACK/UNPACK change.
1271 * print.c (scm_iprin1): SCM_PACK/UNPACK corrections.
1273 * gc.c (scm_gc_sweep): SCM_PACK/UNPACK corrections.
1275 * eval.c (SCM_CEVAL, scm_unmemocar): SCM_PACK/UNPACK corrections.
1277 * dynwind.c (scm_swap_bindings): SCM_PACK/UNPACK corrections.
1279 * async.c, __scm.h: Removed lots of the old async click logic. It
1280 is possible to reinsert it by defining GUILE_OLD_ASYNC_CLICK in
1281 __scm.h. Let's try this out and dump the old code after the
1282 threads reorganization.
1283 (set-tick-rate, set-switch-rate): Conditionally removed.
1285 2000-03-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1287 * gc.c (scm_gc_mark): Bugfix 1: The recent SCM_PACK/UNPACK change
1288 made SCM values into pointers. This turned an arithmetic
1289 computation of the address of the vcell into a pointer-arithmetic
1290 one, thereby screwing up marking of structs.
1291 Bugfix 2: Removed incompletely introduced loop variable `j' used
1292 when protecting the tail array of a struct.
1294 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
1296 * struct.h (SCM_STRUCT_DATA): Don't cast SCM values to pointers.
1298 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
1300 * symbols.h, symbols.c (scm_strhash): Declare the string
1301 parameter as constant, since it is not modified.
1303 * symbols.c (scm_intern_obarray_soft,
1304 scm_sysintern0_no_module_lookup): Can now pass constant strings
1305 to scm_strhash without need for casting.
1307 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
1309 * vectors.h (SCM_VELTS, SCM_VELTS_AS_STACKITEMS): Don't cast SCM
1310 values to pointers. Use SCM2PTR instead.
1312 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
1314 * async.c (scm_set_tick_rate, scm_set_switch_rate): Don't unpack
1315 results of SCM_INUM.
1317 2000-03-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1319 * init.c (scm_boot_guile_1): Renamed GUILE_GC_TRIGGER_1 -->
1320 GUILE_MIN_YIELD_1, GUILE_GC_TRIGGER_2 --> GUILE_MIN_YIELD_2.
1321 GUILE_MIN_YIELD_X now take *positive* fractions of heap size.
1323 * gc.c, gc.h (SCM_MIN_YIELD_1, SCM_MIN_YIELD_2,
1324 min_yield_fraction, min_yield, adjust_min_yield): Renamed from
1325 SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2, gc_trigger_fraction,
1326 gc_trigger, adjust_gc_trigger.
1328 * gc.c (alloc_some_heap): Further improvement of minimal heap size
1330 (SCM_MAX): New macro.
1331 (scm_freelist_t): New field: collected_1. Previous amount of
1333 (gc_sweep_freelist_finish): Trigger based on two last values of
1334 freelist->collected to avoid unnecessary allocation due to
1336 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2):
1337 Adjusted to 45000 cells, 40% and 40%. Gives quick startup
1338 without extra heap allocation.
1340 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
1342 * numbers.h (SCM_MAKINUM): The parameter to SCM_MAKINUM should
1343 already be a C value. No need to unpack it.
1345 * numbers.c (scm_long_long2num): Cast the parameter to scm_bits_t
1346 if we know it fits into an inum.
1348 * ramap.c (ramap_rp): An scm_tc7_[ui]vect object does point to a
1349 field of long values. In contrast, SCM_VELTS accesses a field of
1352 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1354 * gc.c (scm_gc_stats): Inserted explanation of local_scm_mtrigger
1356 (scm_gc_yield_1): New variable: Holds previous yield. Used to
1357 make better judgements.
1358 (gc_sweep_freelist_finish): Inserted explanation of use of
1361 * print.h, stacks.h, options.c, options.h: Changed C++
1364 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
1366 * tags.h (SCM2PTR, PTR2SCM): Use SCM_PACK / SCM_UNPACK correctly.
1368 * numbers.h (SCM_INUMP, SCM_MAKINUM, SCM_INUM0, SCM_COMPLEX_REAL,
1369 SCM_COMPLEX_IMAG, SCM_NUMP, SCM_BDIGITS): Use SCM_PACK /
1370 SCM_UNPACK / SCM2PTR correctly.
1372 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1374 * gc.c (adjust_gc_trigger): Improved documentation.
1375 (alloc_some_heap): Since gc_trigger is used against
1376 freelist->collected, this is the value which should be used to
1377 predict minimum growth.
1379 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
1381 * eval.h: Fix mixup of packed/unpacked SCM values. (Thanks
1382 Thien-Thi Nguyen for the patch.)
1384 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
1386 * numbers.c (scm_ash): Fixed typing problems with the second
1387 parameter and added some documentation. (Thanks Thien-Thi Nguyen
1388 for indicating the problem.)
1390 2000-03-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1392 * gc.c, gc.h (scm_gc_yield): New variable.
1393 (adjust_gc_trigger): Use scm_gc_yield.
1394 (alloc_some_heap): Use scm_gc_yield instead of
1395 scm_gc_cells_collected.
1397 * coop-threads.c: Addd #include "root.h", #include "strings.h".
1399 * debug.c: Added #include "root.h". (Thanks to Thien-Thi Nguyen.)
1401 * gc.c (scm_gc_for_newcell, adjust_gc_trigger): Improved GC
1402 trigger adjustmeant: Take yield (freed cells) for all freelists
1404 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Tuned
1405 to 50000 cell heap with 45% trigger.
1406 (scm_gc_cells_collected): Reintroduced.
1407 (SCM_HEAP_SIZE): New macro.
1408 (scm_gc_sweep): Reintroduced correct computation of
1409 scm_cells_allocated.
1410 (scm_freelist_t): Corrected commentary for field `cluster_size':
1411 Clustersize counts objects, not cells; New member
1412 `clusters_allocated'.
1414 2000-03-19 Michael Livshin <mlivshin@bigfoot.com>
1416 * *.[hc]: add Emacs magic at the end of file, to ensure GNU
1419 2000-03-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1421 * threads.h: Added #include "libguile/throw.h". (Thanks to
1424 2000-03-18 Michael Livshin <mlivshin@bigfoot.com>
1426 * tags.h: (SCM_DOUBLE_CELLP, SCM_NDOUBLE_CELLP): new macros (bad
1427 names, anyone got any better ones?)
1429 * gc.h: (typedef struct scm_freelist_t) remove from here.
1431 * gc.c: (CELL_UP, CELL_DN) made these macros take additional
1432 parameter (the span).
1433 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK) new macros.
1434 (typedef struct scm_freelist_t) moved here from gc.h, it had no
1435 business being externally visible.
1436 (typedef struct scm_heap_seg_data_t) renamed from
1437 scm_heap_seg_data, to be style-compliant.
1438 (scm_mark_locations) if the possible pointer points to a
1439 double-cell, check that it's properly aligned.
1440 (init_heap_seg) align double-cells properly, work with the
1441 assumption that the segment size divides cleanly by cluster size.
1442 (round_to_cluster_size) new function.
1443 (alloc_some_heap, make_initial_segment) use round_to_cluster_size
1444 to satisfy the new init_heap_seg invariant.
1446 2000-03-18 Dirk Herrmann <D.Herrmann@tu-bs.de>

1503 2000-03-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1505 * gc.c, gc.h: Cleanup of the change of 2000-03-15.
1506 Cluster sizes are now independent of GC trigger values.
1507 GUILE_GC_TRIGGER_n can now specify a relative trigger value:
1508 A negative integer gives fraction of total heap size in percent.
1509 (SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Default values set to -40.
1511 * init.c (scm_boot_guile_1): Introduced new variable
1512 GUILE_MAX_SEGMENT_SIZE; New environment variable names:
1513 GUILE_INIT_SEGMENT_SIZE_1, GUILE_GC_TRIGGER_1,
1514 GUILE_INIT_SEGMENT_SIZE_2, GUILE_GC_TRIGGER_2
1516 2000-03-16 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1518 * __scm.h (GC_FREE_SEGMENTS): Disable this until we have made
1519 freeing of segment work with the new GC scheme. (Thanks to
1520 Michael Livshin.) Oops, also happened to make GUILE_NEW_GC_SCHEME
1521 the default, but I'll let this change stay in CVS Guile since this
1522 code is not expected to contain serious bugs.

1526 * gc.c, gc.h (scm_map_free_list): Define also if GUILE_DEBUG is
1528 (scm_free_list_length): New procedure (GUILE_DEBUG).
1529 Fixed a small but serious bug introduced by the previous change.
1531 * gc.c (scm_gc_sweep): Moved variable n_objects to inner sweep
1532 loop and declare as register.
1534 * gc.c (scm_gc_sweep): Sigh... forgot to clear private freelists
1537 Wed Mar 15 08:27:04 2000 Greg J. Badros <gjb@cs.washington.edu>
1539 * fluids.c: Docstring patch from Keisuke Nishida. Some
1540 reindentation, too, and a couple formals renamed. Should
1541 fluid-set! return UNSPECIFIED instead of a value?
1543 Wed Mar 15 08:24:58 2000 Greg J. Badros <gjb@cs.washington.edu>
1545 * Makefile.am: Separate out DOT_X_FILES and DOT_DOC_FILES, and
1546 generate the latter from the concrete listing of the former. Then
1547 make guile-procedures.txt depend on DOT_DOC_FILES instead of
1548 *.doc, so that rebuilding it works.
1550 Wed Mar 15 08:12:14 2000 Greg J. Badros <gjb@cs.washington.edu>
1552 * libguile.h: Include libguile/validate.h. Thanks Keisuke Nishida!
1554 * guile-snarf.awk.in: Replace docstring line-ending \n" and \n\n"
1555 with nothing and \n, respectively. Thanks Keisuke Nishida for
1556 noticing this problem.
1558 2000-03-15 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1560 * __scm.h (GUILE_NEW_GC_SCHEME): Define this if you want to test a
1561 new way of allocating heap. It makes Guile fast, but still
1564 * gc.c, gc.h, pairs.h, init.c: Implementation of a new way of
1565 allocating heap. The basic idea is to trigger GC every Nth
1566 allocated cell and grow heap when free list runs out. The scheme
1567 has been extended so that GC isn't triggered until all remaining
1568 cells are used. The implementation is also prepared for
1569 development in the direction of POSIX threads.
1571 * gc.c (SCM_EXPHEAP): In order to grow by a factor of 1.5,
1572 SCM_EXPHEAP should return half of the heap size.
1574 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1576 The following change to init.c is only enabled if Guile was
1577 configured with --enable-guile-debug.
1579 * init.c (scm_i_getenv_int): New function.
1580 (scm_boot_guile_1): Use the environment variables
1581 GUILE_INIT_HEAP_SIZE, GUILE_INIT_HEAP_SIZE2 to select heap size if
1582 they exist. (This may be replaced by a Scheme level mechanism in
1585 * objprop.c (s_scm_set_object_property_x): Use scm_assq instead of
1586 scm_assoc. (Thanks to Keisuke Nishida.)
1588 2000-03-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1590 * eval.c, lang.c, lang.h (scm_lisp_nil, scm_lisp_t): Renamed from
1591 scm_nil, scm_t. (Thanks to Keisuke Nishida.)
1593 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1595 * init.c (scm_boot_guile_1): Use same initial segment size for
1596 1-word and 2-word segments. Having the smaller size causes Guile
1597 to GC too often. Obviously something needs to be done to allow
1598 for a smaller 2-word segment without this to happen. (The amount
1599 of heap for each type should be automatically adapted to the
1600 application somehow.)
1602 [Almost all of these changes should be documented in the NEWS
1605 * gc.h (scm_freelist_t): New type.
1607 * pairs.h (SCM_NEWCELL, SCM_NEWCELL2): Use new style freelists.
1609 * gc.c (SCM_INIT_HEAP_SIZE): Changed from 32768 --> 40000 so that
1610 all of Guile basics fits into one segment and there suitable room
1612 (SCM_EXPHEAP): Now takes an argument. Grow by a factor of 1.5
1614 (scm_freelist, scm_freelist2): Now of type scm_freelist_t.
1615 Freelists now contains information about object span, cells
1616 collected and amount of cells in heap segments belonging to the
1618 (scm_heap_size, scm_gc_cells_collected): Removed.
1620 * init.c (scm_boot_guile_1): Make 2-word segment 8K (512 cells).
1622 * Makefile.am (libguile_la_LDFLAGS): Bumped library version
1625 * __scm.h eq.c, eval.c, gc.c, gc.h, gh_data, hash.c, numbers.c,
1626 numbers.h, objects.c, ramap.c, random.c, unif.c, unif.h: Extensive
1627 rewrite of handling of real and complex numbers.
1628 (SCM_FLOATS, SCM_SINGLES): These #ifdef conditionals have been
1629 removed along with the support for floats. (Float vectors are
1632 * tags.h (scm_tcs_bignums): Removed.
1633 (scm_tc16_bigpos, scm_tc16_bigneg): Replaced by scm_tc16_big.
1634 Use SCM_BIGSIGN(x) to test for sign!
1635 (scm_tc16_big): The new bignum type.
1636 (SCM_REAL_PART, SCM_IMAG_PART): Removed.
1638 * numbers.h (SCM_BIGSIGN): Sign moved to bit 16.
1639 (scm_makdbl): Deprecated.
1640 (SCM_NEWREAL, SCM_NEWCOMPLEX): New macros.
1641 (SCM_SINGP): Deprecated.
1643 (SCM_INEXP, SCM_CPLXP): Deprecated.
1644 (SCM_INEXACTP, SCM_COMPLEXP): New macros.
1645 (SCM_COMPLEX_REAL, SCM_COMPLEX_IMAG): Renamed from
1646 SCM_REAL, SCM_IMAG (and now only valid for complex numbers).
1647 (SCM_REAL, SCM_IMAG): New, *deprecated*, selectors which work both
1648 for doubles and complex numbers.
1649 (SCM_REAL_VALUE): New selector for doubles.
1650 (scm_double_t, scm_complex_t): New types.
1653 * numbers.c (scm_floprint, scm_floequal): Removed.
1654 (scm_print_real, scm_print_complex, scm_real_equalp,
1655 scm_complex_equalp): New functions.
1657 * unif.c (scm_makflo): Removed.
1659 * smob.h (SCM_SMOB_PREDICATE): New macro.
1660 (SCM_NEWSMOB2, SCM_RETURN_NEWSMOB2, SCM_NEWSMOB3,
1661 SCM_RETURN_NEWSMOB3): New macros.
1663 1999-11-21 Michael Livshin <mlivshin@bigfoot.com>
1665 The following changes implement primitive support for double cells
1666 (i.e. four-word cells) and change the representation of some
1667 things to multi-cells instead of cons+malloc. (Applied and
1670 * pairs.h (SCM_NEWCELL2): double-cell variants of SCM_NEWCELL.
1671 (SCM_CELL_WORD, SCM_CELL_WORDLOC, SCM_SET_CELL_WORD): primitive
1672 multi-cell access macros (used by the ones below).
1673 (SCM_CELL_WORD[0-3], SCM_SET_CELL_WORD[0-3]): multi-cell access
1676 * gc.c (scm_freelist2): multi-cell freelists.
1677 (inner_map_free_list): map_free_list, parameterized on ncells.
1678 "nn cells in segment mm" was misleading for ncells > 1; changed to
1679 "objects". still print cells too, though.
1680 (scm_map_free_list): rewritten using inner_map_free_list.
1681 (scm_check_freelist): get freelist as parameter, since now we have
1683 (scm_debug_newcell2): multi-cell variants of
1685 (scm_gc_for_newcell): take ncells and freelist pointer as
1687 (scm_gc_mark): add case for tc7_pws (procedures with setters are
1689 (scm_gc_sweep): don't free the float data, since it's not malloced
1691 (init_heap_seg): didn't understand what n_new_objects stood for,
1692 so changed to n_new_cells.
1693 (make_initial_segment): new function, makes an initial segment
1694 according to given ncells.
1695 (scm_init_storage): call make_initial_segment, for ncells={1,2,3}.
1697 * numbers.c (scm_makdbl): no malloc'ing needed, so the
1698 {DEFER,ALLOW}_INTS thing removed.
1700 * numbers.h (struct scm_dbl): changed to represent a double cell,
1701 with the number in the second half.
1703 * dynwind.c: changed the wind-guards representation to double
1706 * procs.c, procs.h: changed the procedure-with-setter representation
1709 * async.c, async.h: made async representation a double cell.
1711 * dynl.c: made dynamic_obj representation a double cell.
1713 2000-03-13 Gary Houston <ghouston@arglist.com>
1715 * ports.c (flush_void_port): renamed to flush_port_default.
1716 (end_input_void_port): renamed to end_input_default.
1718 * init.c (scm_standard_stream_to_port): create a void port instead
1719 of opening /dev/null if the standard file descriptors are bad.
1720 advantages: no portability problems, doesn't waste a file descriptor,
1721 simplifies the code (thanks to Marius for the idea).
1723 * vports.c (s_scm_make_soft_port): call scm_port_non_buffer.
1725 * void ports: make reading from a void port give EOF instead of
1727 * ports.c (s_scm_sys_make_void_port): modified docstring.
1728 (fill_input_void_port): new proc.
1729 (scm_init_ports): set up fill_input_void_port.
1730 * ports.c (scm_port_non_buffer): new proc.
1731 (scm_void_port): call scm_port_non_buffer.
1733 * fports.c (scm_setvbuf): docstring: remove the fcntl documentation
1734 which was incorrectly appended.
1736 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1738 * guile-doc-snarf.in: Don't use absolute path for `sed'. (Note
1739 that we can't use autoconf for this. Autoconf itself relies on
1740 the existence of `sed' somewhere on your path.) (Thanks to Dirk
1743 2000-03-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1745 * Makefile.am (libguile_la_SOURCES): Moved iselect.c here from
1746 EXTRA_libguile_la_SOURCES.
1748 * iselect.h: Always declare scm_internal_select.
1750 * iselect.c (scm_internal_select): Added SCM_ASYNC_TICK at the
1751 end. Also let scm_internal_select be a real function also when
1754 * __scm.h (SCM_TICK): Oops! Forgot to put SCM_ASYNC_TICK here...
1756 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1758 * __scm.h (SCM_ALLOW_INTS, SCM_REALLOW_INTS): Removed call to
1759 SCM_ASYNC_TICK. (This is a preparation for POSIX threads support,
1760 and kind of an experiment: Will this cause problems?)
1762 Sun Mar 12 13:26:30 2000 Greg J. Badros <gjb@cs.washington.edu>
1764 * Makefile.am: Added *.doc to DISTCLEANFILES.
1766 2000-03-12 Gary Houston <ghouston@arglist.com>
1768 * fports.c (scm_fdes_to_port): call fcntl F_GETFL to test that
1769 the fdes is valid before doing anything else. check that
1770 the file descriptor supports the modes required.
1771 (scm_fport_buffer_add): don't throw an error if fstat doesn't
1772 work: just use the default buffer size.
1774 * throw.c: change an outdated comment about scm_internal_catch
1775 BODY: it doesn't take a jumpbuf arg.
1777 * init.c (scm_standard_stream_to_port): install a handler in case
1778 scm_fdes_to_port throws an error. don't check here whether the
1779 file descriptor is valid, since scm_fdes_to_port will do that.
1780 set the revealed count depending on whether the port got the
1781 standard file descriptor.
1782 (stream_body_data): new type.
1783 (stream_body, stream_handler): new procs.
1785 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1787 * stacks.c, stacks.h, struct.c, tags.h, unif.c (scm_bits_t):
1788 Renamed from SCMWORD.
1790 * tags.h (SCM_NCELLP): Removed (SCMWORD).
1792 * arbiters.c (SCM_ARB_LOCKED): Use SCM_UNPACK_CAR.
1794 * async.c, boolean.h, debug.c, dynl.c, dynwind.c, eval.c, eval.h,
1795 feature.h, filesys.h, fluids.h, fports.c, fports.h, gc.c, gc.h,
1796 hash.c, keywords.h, macros.c, numbers.c, numbers.h, objects.c,
1797 objects.h, options.c, pairs.h, ports.c, ports.h, print.c,
1798 procs.h, ramap.c, read.c, smob.c, smob.h, srcprop.h, stacks.c,
1799 stacks.h, strports.c, struct.c, struct.h, tag.c, tags.h,
1800 throw.c, unif.c, unif.h, variable.h, vectors.h, weaks.c,
1801 weaks.h (SCM_PACK, SCM_UNPACK, SCM_UNPACK_CAR): Renamed from
1802 SCM_ASSCM, SCM_ASWORD, SCM_CARW).
1804 * numbers.h (SCM_SRS, SCM_INUM): Corrected SCM_ASSCM/ASWORD fixes.
1806 * alist.c, eval.c, net_db.c, posix.c, print.c, snarf.h, struct.c,
1807 tags.h: Fixed copyright notices.
1809 * struct.c, coop-threads.c: SCM_ASSCM/ASWORD fixes.
1811 2000-03-12 Marius Vollmer <mvo@zagadka.ping.de>
1813 * init.c (scm_standard_stream_to_port): Check whether the file
1814 descriptor is valid and substitute "/dev/null" when not.
1816 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1818 * coop-defs.h (struct timespec): Conditionally defined.
1820 * coop.c (coop_condition_variable_timed_wait_mutex): Use ETIMEDOUT
1823 * readline.c (match_paren): Bugfix: First arg to select is not
1824 number of descriptors but the number of the highest descriptor +
1827 This is a preliminary attempt at a cleanup of the threads support
1828 code. It moves things to better places, makes arguments more
1829 consistent with the POSIX API (which is used in GNOME's glib), and
1830 adds new functionality.
1832 * readline.c (scm_init_readline): Added new arg to scm_init_mutex.
1834 * coop-defs.h (scm_mutex_trylock): New macro: alias for
1836 (scm_cond_init): Changed definition to
1837 coop_new_condition_variable_init.
1839 * coop.c: #include <errno.h>
1840 (coop_timeout_qinsert): Moved here from iselect.c
1841 (coop_new_mutex_init, coop_new_condition_variable_init): New
1842 functions. The strange names are temporary. Use scm_mutex_init
1843 and scm_cond_init instead.
1844 (coop_mutex_trylock): New function. Uses errno.h:EBUSY. errno.h
1845 is ANSI C, but should we check for individual error codes in
1847 (coop_condition_variable_timed_wait_mutex): New function.
1848 (coop_key_create, coop_setspecific, coop_getspecific,
1849 coop_key_delete): New functions.
1851 * iselect.c (coop_timout_qinsert): Moved to coop.c
1853 2000-03-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1855 * pairs.h (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR,
1856 SCM_SETOR_CDR): Corrected SCM_ASSCM/WORD fixes.
1858 * tags.h (SCM_VOIDP_TEST): Renamed from VOIDP_TEST.
1861 * objects.h (SCM_CLASS_FLAGS, SCM_OBJ_CLASS_FLAGS,
1862 SCM_SET_CLASS_INSTANCE_SIZE), struct.h (SCM_STRUCT_VTABLE_DATA),
1863 proc.h (SCM_CLOSCAR): SCM_ASSCM/WORD fixes.
1865 * eval.c (scm_lookupcar1): Inserted SCM_ASWORD in expressions
1868 2000-03-11 Dale P. Smith <dpsm@en.com>, applied by Greg J. Badros, <gjb@cs.washington.edu>
1870 * numbers.c (scm_copy_big_dec, scm_copy_smaller, scm_big_ior,
1871 scm_big_xor, scm_big_and, scm_big_test): Added new lowlevel bignum
1872 logical functions from SCM.
1874 (logand, logior, logxor, logtest, logbit?): Extended scheme
1875 logical functions to use bignums from SCM.
1877 (lognot): Removed call to `SCM_VALIDATE_INUM' that prevented
1878 lognot from using bignums.
1880 Thu Mar 9 11:33:25 2000 Greg J. Badros <gjb@cs.washington.edu>
1882 * vectors.h (SCM_VELTS_AS_STACKITEMS): Added this macro to help in
1883 eliminating some warnings.
1885 * unif.c, strports.c, print.c, options.c: Fix some warnings on
1888 * gc.c, gc.h: Added scm_return_first_int(), and added comment re:
1889 what the scm_return_first* functions do.
1891 2000-03-09 Han-Wen Nienhuys <hanwen@cs.uu.nl>, applied by Greg J. Badros, <gjb@cs.washington.edu>
1893 * libguile/*.[ch]: make a distinction between SCM as a generic
1894 name for a Scheme object (now a void*), and SCM as 32 bit word for
1895 storing tags and immediates (now a long int). Introduced
1896 SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
1897 code in the process: arbiter.c (use macros), unif.c (scm_array_p),
1899 Wed Mar 8 10:15:59 2000 Greg J. Badros <gjb@cs.washington.edu>
1901 * numbers.c: Use SCM_VALIDATE_LONG_COPY, and longs, not ints, in
1902 various logXXX primitives. Thanks Eric Moore!
1904 Tue Mar 7 08:05:22 2000 Greg J. Badros <gjb@cs.washington.edu>
1906 * run-test, remaining-docs-needed: Added these scripts. The
1907 second one is only temporary until the docstring additions are
1908 complete. run-test may best live on, but is here mostly for
1909 convenience and awareness for now.
1911 * hash.c: Docs, minor cleanup patch from Dirk Herrman.
1913 Thu Mar 2 16:06:58 2000 Greg J. Badros <gjb@cs.washington.edu>
1915 * error.h, error.c: Added `scm_wrong_type_arg_msg' to support
1916 displaying the expected type. Use SCM_LISTn in a couple places
1917 instead of scm_cons-ing by hand.
1919 * __scm.h: Added SCM_ASSERT_TYPE macro.
1921 * validate.h, scm_validate.h: Added the former, as a renamed
1922 version of the latter with SCM_ASSERT_TYPE used in
1923 SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
1925 * Makefile.am: Rename scm_validate.h to validate.h.
1927 * *.c, *.h: Include validate.h, not scm_validate.h (old name's
1928 prefix was superfluous).
1930 Thu Mar 2 15:33:12 2000 Greg J. Badros <gjb@cs.washington.edu>
1932 * hashtab.c: Improved documentation for lots of functions. Added
1933 handwritten docs for `hash-fold'.
1935 Thu Mar 2 15:13:25 2000 Greg J. Badros <gjb@cs.washington.edu>
1937 * list.c: Added hand-written docs for `del{q,v,ete}1!'.
1939 Thu Mar 2 12:38:30 2000 Greg J. Badros <gjb@cs.washington.edu>
1941 * list.c: Moved append docs to append! Thanks Dirk Hermann. Also,
1942 added append docs from R4RS.
1944 * strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
1945 Thanks Dirk Hermann!
1947 * chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
1948 deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR. Thanks Dirk Hermann!
1950 * *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
1951 Drop use of SCM_P for function prototypes... assume an ANSI C
1952 compiler. Thanks Dirk Hermann!
1954 Sat Feb 19 12:20:12 2000 Greg J. Badros <gjb@cs.washington.edu>
1956 * ports.c: Made `set-port-column!' and `set-port-line!' each
1957 return SCM_UNSPECIFIED instead of a (not-scheme-object) integer
1958 that caused a seg fault. Also fixed `set-port-column!'s
1959 docstring. Thanks Han-Wen Nienhuys for finding the bug!
1961 Sun Feb 13 19:11:42 2000 Greg J. Badros <gjb@cs.washington.edu>
1963 * arbiters.c, eq.c, gc.c, guardians.c, list.c, ports.c, print.c,
1964 regex-posix.c, scmsigs.c, stime.c, strings.c, variable.c, stime.c,
1965 strings.c, variable.c: Added lots of documentation, cleaned up
1966 some existing documentation. Occasionally changed formal params
1967 to match docs. Also folded an #ifdef into the inners of a
1968 primitive instead of having two copies of the primitive
1969 (`get-internal-real-time', from stime.c)
1971 Sun Feb 13 18:12:19 2000 Greg J. Badros <gjb@cs.washington.edu>
1973 * ports.c: Added docs for primitives missing them. Written by
1976 Sun Feb 13 09:40:36 2000 Greg J. Badros <gjb@cs.washington.edu>
1978 * guile-doc-snarf.in: Use ${AWK} -f guile-func-name-check, not
1979 just execing guile-func-name-check. Thanks Michael Livshin!
1981 Thu Feb 10 11:43:23 2000 Greg J. Badros <gjb@cs.washington.edu>
1983 * guile-snarf.awk.in: Tweak to work with Sun/HP awk, removed some
1984 dead code. Patch from Michael Livshin.
1986 * guile-doc-snarf.in: Tweak to work with Sun/HP sh. Patch from
1989 2000-02-09 Gary Houston <ghouston@arglist.com>
1991 * init.c (scm_init_standard_ports): when stdout is a tty, make the
1992 current-output-port unbuffered by default. this is less confusing
1993 for interactive use. it was line-buffered because of a
1994 performance problem with unbuffered ports, but I think it will be
1997 2000-02-08 Gary Houston <ghouston@arglist.com>
1999 * __scm.h: don't define long_long or ulong_long if HAVE_LONG_LONGS
2002 * stime.c (scm_localtime, scm_mktime): if neither HAVE_TM_ZONE nor
2003 HAVE_TZNAME are defined, use an empty string instead of giving two
2004 spurious compile-time errors.
2006 Tue Feb 8 13:57:46 2000 Greg J. Badros <gjb@cs.washington.edu>
2008 * ports.c: Doc patches from Richard Kim. Pasted from MIT Scheme.
2011 Mon Feb 7 09:07:31 2000 Greg J. Badros <gjb@cs.washington.edu>
2013 * macros.c: Doc patches from Richard Kim. Pasted from scm.texi.
2015 Sun Feb 6 20:26:21 2000 Greg J. Badros <gjb@cs.washington.edu>
2017 * pairs.c: Doc patches from Richard Kim. Pasted from MIT Scheme
2018 (which is GNU GPL'd).
2020 2000-01-31 Gary Houston <ghouston@arglist.com>
2022 * strings.h: don't use SCM_P. don't include <string.h>.
2023 * error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>.
2025 * strings.c (scm_string_ref): make the 2nd argument compulsory.
2026 previously it defaulted to zero for no good reason that I can see.
2027 use a local variable for SCM_INUM (k). replace
2028 SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
2030 (scm_makfromstr): cosmetic changes.
2032 (scm_string): Accept only chars in the list, not strings, for
2033 conformance to R5RS (particularly for list->string, which is
2034 supposed to be the inverse of string->list.) remove
2035 SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
2036 scm_makstr handles the cell allocation. when reporting wrong-type
2037 arg, don't report the position as 1.
2039 * posix.c (scm_init_posix): intern PIPE_BUF if it's defined.
2041 2000-01-29 Gary Houston <ghouston@arglist.com>
2043 * posix.c (scm_pipe): rewrote the docstring.
2045 * filesys.c (scm_select, retrieve_select_type, get_element,
2046 fill_select_type, set_element): modified so that Scheme
2047 "select" tests port buffers for the ability to provide input
2048 or accept output. Previously only the underlying file descriptors
2049 were checked. Rewrote the docstring.
2051 Thu Jan 27 10:14:25 2000 Greg J. Badros <gjb@cs.washington.edu>
2053 * vectors.c, symbols.c, strorder.c: Documentation cut and pasted
2054 from Gregg Reynolds. Thanks Gregg!
2056 Thu Jan 27 09:59:38 2000 Greg J. Badros <gjb@cs.washington.edu>
2058 * strop.c (scm_i_index): Obfuscated commented-out SCM_DEFINE by
2059 adding "x" prefix to the line so that guile-func-name-check
2060 doesn't complain unnecessarily.
2062 Wed Jan 26 17:33:52 2000 Greg J. Badros <gjb@cs.washington.edu>
2064 * throw.c: Factor out an #ifdef/#else/#endif choice more finely
2065 for maintainability.
2067 * strop.c: Documentation added by Gregg A. Reynolds. Pasted in
2070 Wed Jan 26 10:02:11 2000 Greg J. Badros <gjb@cs.washington.edu>
2072 * tag.c: Added doc for `tag', but mark as deprecated since Mikael
2073 suggests removing tag.c altogether (and using a new `class-of'
2076 * strings.c: Added documentation from Gregg A. Reynolds. Edited
2077 a bit by me to use FOO instead of @var{foo} and to have the
2078 summary come before preconditions on input. Also dropped trailing
2081 * gsubr.c: Do not use SCM_DEFINE for `gsubr-apply'. Register the
2082 function with scm_make_subr_opt w/ last arg of 0 so it is not
2083 visible at the Scheme level. Mikael says that this is the right
2084 thing because the first arg to the proc is the guts of a compiled
2085 closure and shouldn't be exposed to the Scheme level.
2087 Tue Jan 25 17:15:47 2000 Greg J. Badros <gjb@cs.washington.edu>
2089 * sort.c: typo in comment fixed.
2091 * keywords.c: Added documentation.
2093 * guardians.c: Added documentation (could be better).
2095 * gc.c: Added docs for gc-set-debug-check-freelist.
2097 * eq.c: Added docs for eq?, eqv? equal? abridged from R4RS.
2099 * boolean.c: Added docs for `not', `boolean?' (by hand).
2101 Tue Jan 25 13:28:56 2000 Greg J. Badros <gjb@cs.washington.edu>
2103 * random.c: Added documentation, from SLIB page:
2104 http://angela.ctrl-c.liu.se/~calle/scheme/slib_toc.html
2106 Mon Jan 24 17:50:20 2000 Greg J. Badros <gjb@cs.washington.edu>
2108 * variable.c, version.c: Added documentation, written by hand
2109 since I could not find anything already written that was
2112 2000-01-23 Gary Houston <ghouston@arglist.com>
2114 * filesys.c (scm_chown): omit port/fdes support if HAVE_FCHOWN is
2115 not defined (thanks to Richard Y. Kim).
2117 Thu Jan 20 13:00:38 2000 Greg J. Badros <gjb@cs.washington.edu>
2119 * Makefile.in: Removed, this is auto-generated.
2121 Thu Jan 20 11:33:47 2000 Dirk Hermann <dirk@ida.ing.tu-bs.de> --applied 01/20/00 gjb
2123 * list.c: Put some variable initialization code at the point of
2124 declaration; Added a comment for list*; Formatting changes.
2126 * load.c: use SCM_NNULLP to make sure the end of a list is not
2129 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2131 * backtrace.c (scm_display_error_message): Bugfix: Don't use
2132 result of scm_list_p as C boolean.
2133 (scm_display_error_message, scm_set_print_params_x): Use new
2134 validation macros. (Thanks to Dirk Herrmann.)
2136 * net_db.c (scm_resolv_error): Cast result from hstrerror.
2138 * strports.c (st_end_input): Inserted parenthesis to get operator
2141 * list.h (scm_init_list): Removed SCM_P around prototypes.
2143 * fports.c, list.c, numbers.c, ports.c, stime.c, symbols.c,
2144 filesys.c, posix.c: Converted docstrings to ANSI C format and
2145 escaped " occurring inside string literals.
2147 Tue Jan 18 13:21:08 2000 Mikael Djurfeldt <mdj@r11n07-s.pdc.kth.se>
2149 * posix.c (scm_mknod): Escape " occuring inside docstring.
2151 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2153 * alist.c, chars.c, debug.c, dynl.c, dynwind.c, error.c, eval.c,
2154 evalext.c, filesys.c, gc.c, hash.c, hashtab.c, ioext.c,
2155 keywords.c, list.c, load.c, macros.c, net_db.c, numbers.c,
2156 objprop.c, ports.c, posix.c, print.c, procprop.c, procs.c,
2157 ramap.c, regex-posix.c, root.c, scmsigs.c, simpos.c, socket.c,
2158 stacks.c, stime.c, strings.c, strop.c, strports.c, struct.c,
2159 symbols.c, throw.c, unif.c, vectors.c, version.c, vports.c,
2160 weaks.c: Converted docstrings to ANSI C format.
2162 * filesys.c (scm_chmod), simpos.c (scm_system), version
2163 (scm_version), vports (scm_make_soft_port): Escape " occuring
2166 Mon Jan 17 11:41:22 2000 Greg J. Badros <gjb@cs.washington.edu>
2168 * scm_validate.h: Added SCM_VALIDATE_ULONG_COPY,
2169 SCM_VALIDATE_LONG_COPY
2171 * numbers.c: Use SCM_VALIDATE_ULONG_COPY, instead of
2172 SCM_VALIDATE_INUM_COPY to let bigger numbers be used. Rename a
2173 couple of formal arguments (and fix their uses) to make arguments
2174 match the documentation.
2176 2000-01-14 <mstachow@alum.mit.edu>
2178 * Makefile.am: Augment path when running guile-doc-snarf so
2179 guile-func-name-check is found.
2181 Fri Jan 14 09:34:55 2000 Greg J. Badros <gjb@cs.washington.edu>
2183 * scm_validate.h (SCM_NUM2LONG_DEF): Fix this macro to just use
2184 def, not SCM_MAKINUM(def); thanks Janis Bzerins!
2186 Wed Jan 12 00:06:53 2000 Greg J. Badros <gjb@cs.washington.edu>
2188 * net_db.c (s_scm_inet_makeaddr): Use SCM_NUM2ULONG since that's
2189 the way guile-1.3.4 worked, but #if 0 out the version using
2190 SCM_VALIDATE_INUM_COPY for stricter testing.
2192 Tue Jan 11 18:24:18 2000 Greg J. Badros <gjb@cs.washington.edu>
2194 * guile-doc-snarf.in: Use new $fullfilename for running
2195 guile-func-name-check, and put "$fullfilename" and "$filename" in
2196 quotes at uses to make sure re-splitting on whitespace does not
2197 occur (so filenames w/ embedded whitespace would work okay, though
2198 I sure hope we never have to deal with that! :-) ). Thanks to
2199 Mikael for pointing out the source_dir != build_dir was broken.
2201 Tue Jan 11 17:42:40 2000 Greg J. Badros <gjb@cs.washington.edu>
2203 * scm_validate.h: Added SCM_NUM2LONG_DEF macro. Make
2204 SCM_OUT_OF_RANGE use SCM_MAKINUM, not scm_long2num. Added
2205 SCM_COERCE_ROSTRING macro. Added SCM_VALIDATE_NONEMPTYLIST
2206 macro. Fix SCM_VALIDATE_STRINGORSUBSTR macro to not use SLOPPY
2209 * ports.c (scm_port_closed_p): Validate that the arg is a PORT,
2210 then return whether it's an open port (was validating that it was
2211 an open port -- this was a bug I introduced back in December, but
2212 my careful reading of diffs caught it).
2214 * numbers.c: Recombine the two conditional-compilation paths for
2215 all the log* primitives -- they were split based on #ifndef
2216 scm_long2num; factored out a SCM_LOGOP_RETURN macro, and fixed
2217 some bugs and inconsistencies in the two sets of implementations.
2218 (scm_lognot) Fixed *atrocious* re-use of a SCM as an integer!
2220 * ioext.c: Use SCM_ASSERT_RANGE in a couple places, and
2221 SCM_VALIDATE_INUM_COPY once where it should've been used.
2223 * fluids.c (scm_internal_with_fluids): Use
2224 SCM_VALIDATE_LIST_COPYLEN.
2226 * filesys.c: Use SCM_NUM2LONG instead of SCM_VALIDATE_INUM_COPY;
2227 this is questionable as it relaxes type safety, but other changes
2228 were useful and all SCM_NUM2LONG's should probably be
2229 revisited. Use SCM_OUT_OF_RANGE, SCM_WRONG_TYPE_ARG.
2231 * evalext.c: line-break change on 1 line.
2233 * eval.c (nconc2last): Takes a non-empty list as its first
2234 argument, not just a list.
2236 * dynl.c: Use new SCM_COERCE_ROSTRING macro.
2238 Tue Jan 11 15:44:23 2000 Greg J. Badros <gjb@cs.washington.edu>
2240 * dynl.c, feature.c, filesys.c, fports.c, list.c, load.c,
2241 net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
2244 * symbols.c (scm_sysintern0): Fixed the function name in a
2245 scm_misc_error invocation.
2247 * print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
2248 use scm_return_first to ward off latent GC bug that Mikael caught.
2250 * async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
2251 used before but should've been.
2253 2000-01-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2255 * snarf.h (SCM_PROC1): Replaced SCM (*) (...) with
2256 SCM_FUNC_CAST_ARBITRARY_ARGS.
2258 Tue Jan 11 13:44:07 2000 Greg J. Badros <gjb@cs.washington.edu>
2260 * guile-func-name-check.in: Added this script to statically check
2261 #define FUNC_NAME, #undef FUNC_NAME in the source.
2263 * sort.c, posix.c: Fix #undef FUNC_NAME lines to not have trailing
2264 redundant comment, semicolon; caught by new guile-func-name-check
2267 * debug.c: Fix mistaken #define FUNC_NAME for scm_make_iloc.
2268 Caught by new guile-func-name-check-script.
2270 * Makefile.am: Added guile-func-name-check to bin_SCRIPTS
2272 * ramap.c: Fix #if 0'd out code to be syntactically acceptable to
2273 guile-func-name-check.
2275 * guile-doc-snarf.in: Run guile-func-name-check on the file before
2278 Tue Jan 11 11:31:10 2000 Greg J. Badros <gjb@cs.washington.edu>
2280 * fports.c, ports.c, ports.h, strports.c, vports.c: Make write
2281 port function take const void*, not void*.
2283 Tue Jan 11 11:18:07 2000 Greg J. Badros <gjb@cs.washington.edu>
2285 * scm_validate.h, chars.c, ports.c, print.c, read.c, strings.c,
2286 strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
2287 SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY. Change made for
2288 consistency with the other macros dealing with immediate
2289 characters. (Similar to INT -> INUM change a week or so ago).
2291 Tue Jan 11 10:41:46 2000 Greg J. Badros <gjb@cs.washington.edu>
2293 * dynl.c, error.c, eval.c, feature.c, filesys.c, fports.c, list.c, load.c,
2294 net_db.c, read.c, socket.c: Update error messages to use ~A for
2295 %s, ~S for %S to work with new `simple-format' format and be
2296 standardized better.
2298 * print.h, print.c (scm_simple_format): Added `simple-format'
2299 primitive. It's the old scm_display_error, with ARGS now a rest
2300 parameter, and the destination first instead of last (and a couple
2301 new capabilities inspired by `format' -- #t as destination means
2302 current-output-port, #f means return the formatted text as a
2305 * gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
2307 * backtrace.c (scm_display_error_message): Rewrote to use
2308 scm_simple_format() procedure.
2310 * __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
2312 2000-01-09 Marius Vollmer <mvo@zagadka.ping.de>
2314 Finally applied the libltdl patch from Thomas Tanner, with slight
2317 * DYNAMIC-LINKING: Removed because it is obsolete.
2318 * dynl.c: Use ANSI prototypes.
2319 (sysdep_dynl_link): Use lt_dlopenext instead of lt_dlopen.
2320 * scmconfig.h.in: Do not change, as it is automatically generated.
2322 1999-07-25 Thomas Tanner <tanner@ffii.org>
2324 * dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c: deleted
2326 * Makefile.am: likewise, add INCLTDL (libltdl headers) to
2327 INCLUDES, set dlpreopened files in LDFLAGS, link libguile
2329 * dynl.c: use libltdl if DYNAMIC_LINKING is enabled,
2330 * guile.c: register preloaded modules
2331 * scmconfig.h.in: remove obsolete symbols
2333 2000-01-09 Gary Houston <ghouston@arglist.com>
2335 * These changes should make it unnecessary to call tzset from
2336 Scheme after modifying the TZ environment variable, even if the
2337 system date facilities cache the value.
2338 * stime.c (setzone, scm_localtime): added comments.
2339 (tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
2340 (setzone): don't call tzset.
2341 (restorezone): call tzset only if HAVE_TZSET is defined.
2342 (scm_tzset): don't define if HAVE_TZSET not defined. Change the
2343 doc string to indicate that this procedure isn't likely to do
2345 (scm_localtime, scm_strftime, scm_mktime): call tzset if
2346 LOCALTIME_CACHE is defined.
2348 2000-01-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2350 * posix.c (scm_sync): Return SCM_UNSPECIFIED.
2352 2000-01-09 Gary Houston <ghouston@arglist.com>
2354 * eval.c: define scm_unbound_variable_key ('unbound-variable).
2355 scm_lookupcar1: throw an error with key 'unbound-variable instead
2356 of 'misc-error when an unbound variable is encountered.
2358 * filesys.c (scm_mkdir, scm_rmdir, scm_getcwd, scm_select,
2359 scm_symlink, scm_readlink, scm_lstat),
2360 posix.c (scm_setpgid, scm_setsid, scm_ctermid, scm_tcgetpgrp,
2361 scm_tcsetpgrp, scm_uname, scm_setlocale, scm_mknod, scm_nice,
2363 simpos.c (scm_system),
2364 stime.c (scm_times, scm_strptime):
2365 move the HAVE_XXX feature tests out of the procedure bodies.
2366 don't use SCM_SYSMISSING.
2367 scm_validate.h (SCM_SYSMISSING): removed.
2368 error.h, error.c (scm_sysmissing): comment that this is deprecated.
2369 see ChangeLog entry for 1999-12-28.
2371 Sat Jan 8 19:52:04 2000 Greg J. Badros <gjb@cs.washington.edu>
2373 * scm_validate.h (SCM_VALIDATE_BOOL_COPY): Fix typo.
2375 Sat Jan 8 17:06:46 2000 Greg J. Badros <gjb@cs.washington.edu>
2377 * backtrace.c: Fix spelling typo in a comment.
2379 * snarf.h: Use new SCM_DOCS macro to encapsulate the non SCM_INIT
2380 text. Reformatted some of the expansions.
2382 Fri Jan 7 15:50:46 2000 Greg J. Badros <gjb@cs.washington.edu>
2384 * scm_validate.h (SCM_OUT_OF_RANGE): Use scm_out_of_range_pos to
2385 report the position of the argument.
2387 * error.h, error.c (scm_out_of_range_pos): Added this function to
2388 take extra "pos" argument, the position number of the errant
2391 * debug.c: Use SCM_OUT_OF_RANGE instead of scm_out_of_range.
2393 * snarf.h: Use SCM_HERE and SCM_INIT as names, not SCM_NOTSNARF
2394 and SCM_SNARFING. Also put the %%% in the SCM_INIT since Mikael
2395 prefers that and I'm reasonably indifferent.
2397 Fri Jan 7 15:03:32 2000 Greg J. Badros <gjb@cs.washington.edu>
2399 * snarf.h: Factor out differences between C++ and non-C++ into
2400 SCM_FUNC_CAST_ARBITRARY_ARGS macro. Modify all the snarf macro
2401 definitions to use SCM_NOTSNARF and SCM_SNARFING macros (like
2402 Mikael's macros, below, but changed names and SCM_SNARFING no
2403 longer expands to include %%% -- that must appear in the argument
2404 so that the token appears at the call-site as a reminder).
2406 2000-01-07 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2408 * snarf.h (SCM_INSITU, SCM_INIT): New snarf macros for use in user
2409 snarf macro definitions.
2411 2000-01-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2413 * chars.c (scm_integer_to_char): Use Greg's nice
2414 SCM_VALIDATE_INUM_RANGE macro for argument checking for closer
2417 Thu Jan 6 11:48:49 2000 Greg J. Badros <gjb@cs.washington.edu>
2419 * *.c, snarf.h: Replace GUILE_PROC1 with SCM_DEFINE1 throughout.
2421 Thu Jan 6 11:22:53 2000 Greg J. Badros <gjb@cs.washington.edu>
2423 * Makefile.am (ETAGS_ARGS): Switch to SCM_DEFINE, SCM_DEFINE1
2424 instead of GUILE_PROC.
2426 Thu Jan 6 11:21:49 2000 Greg J. Badros <gjb@cs.washington.edu>
2428 * alist.c: Do not report mismatch errors on some uses of `tmp' (do
2429 this by using SCM_ARG2 instead of `2' in the SCM_VALIDATE_CONS
2432 Thu Jan 6 09:54:33 2000 Dirk Herrmann <dirk@ida.ing.tu-bs.de> --gjb applied
2434 * scm_validate.h: Remove some redundant NIMP tests.
2436 * alist.c: minimize scope of the tmp variables, and initialize
2437 them when declared. The strange SCM_NIMP tests are replaced by
2438 SCM_CONSP tests that more closely reflect the intended semantics.
2439 However, we don't get a performance penalty here, because the
2440 SCM_CONSP test was performed by the ALISTCELL test anyway. * The
2441 extremely ugly use of ASRTGO macros was removed: The calls to
2442 ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a
2443 label parameter that only exists when SCM_RECKLESS is not defined.
2444 This works, because ASRTGO itself is defined in a way that it only
2445 makes use of the label parameter if SCM_RECKLESS is not defined
2446 (shudder!). Does guile make at all use of the possibility to
2447 define SCM_RECKLESS? * Codesize is likely to be reduced, since
2448 instead of two calls to SCM_ASSERT performed by the ALISTCELL test
2449 we now only get one test.
2451 * list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate. Also use
2452 SCM_NULLP instead of SCM_IMP. Drop use of "register" keyword on
2453 some variables in `list?'. Fix `reverse' and `reverse!'
2454 primitives to handle improper lists better.
2456 Wed Jan 5 11:24:53 2000 Greg J. Badros <gjb@cs.washington.edu>
2458 * *.[ch]: Whitespace changes -- added space after SCM_VALIDATE_*
2459 macros and SCM_DEFINE macros to match GNU coding standards.
2461 Wed Jan 5 11:04:24 2000 Greg J. Badros <gjb@cs.washington.edu>
2463 * *.[ch]: Replace GUILE_PROC w/ SCM_DEFINE.
2465 Wed Jan 5 10:59:06 2000 Greg J. Badros <gjb@cs.washington.edu>
2467 * *.[ch]: Replace SCM_VALIDATE_INT w/ SCM_VALIDATE_INUM for
2468 better consistency with the names of other SCM_VALIDATE_ macros
2469 and better conformance to guile naming policy.
2471 Wed Jan 5 10:50:39 2000 Greg J. Badros <gjb@cs.washington.edu>
2473 * ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a
2474 SCM_VALIDATE instead of 1 to avoid a check on the argument (since
2475 it's not the actual name of the formal).
2477 * guile-snarf.awk.in: Do argument/number mismatch checking and
2478 print warnings in an Emacs compile-mode parseable format.
2480 * struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/
2481 SCM_OUTOFRANGE as 3rd argument.
2483 * random.c: Fix argument/number mismatch (that I introduced :-( ).
2485 * __scm.h: Do not #define SCM_ARG* when snarfing;
2486 lets us distinguish between 1 and SCM_ARG1 when snarfing as only
2487 the former (using the number) requires the argument to match the
2488 formal in the current argument snarfing check.
2490 * snarf.h: Give new definition of SCM_ASSERT when in
2491 snarfing mode to output a lexically-identifiable sequence that the
2492 guile-snarf.awk script uses to verify argument/position matching.
2494 * ramap.c: Remove extraneous #undef FUNC_NAME.
2496 Wed Jan 5 08:36:38 2000 Greg J. Badros <gjb@cs.washington.edu>
2498 * guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the
2499 current version of the same functionality; it writes the .x output
2500 to stdout instead of directly into the file.
2502 Wed Jan 5 08:15:04 2000 Greg J. Badros <gjb@cs.washington.edu>
2504 * unif.c, symbols.c, strings.c, stacks.c, random.c, print.c,
2505 posix.c: Eliminated a bunch of SCM_NIMP(..)s that are now
2506 redundant with the safer macros. Patch from Dirk Hermann applied
2507 by hand. Thanks Dirk!
