3 * guile-doc-snarf.in: put the preprocessed file through sed to
4 trim all lines to 512 chars. I hope it doesn't break anybody's
7 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): reverted
8 the previous change to this macros, after deciding to torture the
11 2000-05-21 Michael Livshin <mlivshin@bigfoot.com>
13 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): brought
14 the yucky, ugly and nasty conditional compilation back. sorry,
15 but it was either that or requiring GAWK to build Guile.
16 (lots of places): removed the code that implemented the old GC
19 * init.c (scm_boot_guile_1): removed the code conditioned on
22 * __scm.h: (GUILE_NEW_GC_SCHEME): removed.
24 * gc.c (scm_protect_object, scm_unprotect_object): change the
25 implementation to more efficient (at least in the time complexity
26 sense). the calls should now also be thread-safe -- I suspect
27 that people expect them to be. (thanks to Han-Wen Nienhuys)
28 (lots of places): removed the code that implemented the old GC
31 * hashtab.c (scm_hash_fn_create_handle_x): add missing
32 SCM_REALLOW_INTS before return. I really wonder about the
33 possible interactions between hashtables, threads & GC. it
34 doesn't look healthy at all.
36 2000-05-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
38 * unif.c (scm_bit_count): Fixed the parameter checks. Thanks to
41 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
43 * __scm.h (SCM_DEBUG_CELL_ACCESSES), gc.h (SCM_): Added as a new
44 debug option to verify all accesses to cells actually access
47 * gc.h (SCM_VALIDATE_CELL): Added. Only performs validation if
48 SCM_DEBUG_CELL_ACCESSES is set to 1.

76 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
78 * __scm.h (SCM_DEBUG_REST_ARGUMENT): Renamed from
79 SCM_DEBUG_REST_ARGUMENTS in order to clarify that we don't test
80 the actual arguments in the list, but rather the rest argument as
83 * validate.h (SCM_VALIDATE_REST_ARGUMENT): Added.
85 * async.c (scm_noop), eval.c (scm_map, scm_for_each), list.c
86 (scm_list_star, scm_append, scm_append_x), ports.c

89 (scm_make_stack), strings.c (scm_string_append), struct.c
90 (scm_make_struct, scm_make_vtable_vtable): Validate rest arguments.
92 * dynl.c (DYNL_GLOBAL, sysdep_dynl_link, kw_global, sym_global,
93 scm_dynamic_link, scm_init_dynamic_linking), dynl.h
94 (scm_dynamic_link): Removed possibility to pass flags to
95 scm_dynamic_link, as it had no effect anyway.
97 * filesys.c (scm_fcntl): Made single optional rest argument into
98 a standard optional argument.
100 * hooks.c (scm_run_hook): A list of rest arguments is never
103 * list.c (scm_append, scm_append_x), stacks.c (scm_make_stack),
104 strings.c (scm_string_append): Don't perform half-hearted checks
105 to see whether the rest argument forms a proper list any more, use
106 SCM_VALIDATE_REST_ARGUMENTS instead.

111 * posix.c (scm_convert_exec_args), print.c (scm_simple_format):
112 Simplify verification of rest argument.

115 (ss_handler, handler_message): Make first mandatory rest argument
116 of scm_make_stack into a standard mandatory argument.
118 * unif.c (scm_transpose_array, scm_enclose_array,
119 scm_array_in_bounds_p), unif.h (scm_transpose_array,
120 scm_enclose_array, scm_array_in_bounds_p): Make first mandatory
121 rest argument into a standard mandatory argument.
123 2000-05-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
125 * __scm.h: Added SCM_DEBUG as default debug option. (Thanks to
126 Keisuke Nishida for the suggestion.) Added debug option
127 SCM_DEBUG_REST_ARGUMENTS.
129 * eval.c (scm_map, scm_for_each): Make sure all lists have the
130 same length. Also, removed redundant parameter checks.
132 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
134 * Makefile.am: Let 'make clean' remove *.x and *.doc files.
136 * __scm.h: Improved explanation of giving options to make.

144 (scm_remainder, scm_modulo), numbers.h (SCM_SRS, SCM_MAKINUM,
145 SCM_INUM): Removed conditionally compiled code for Turbo C.
147 * gdbint.c (gdb_maybe_valid_type_p): Eliminated call to scm_tag.
148 That check can be assumed to be redundant except for very rare
149 conditions that actually indicate broken heap data.
151 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
153 * numbers.c (scm_logcount, scm_integer_length): Reordered
156 2000-05-15 Gary Houston <ghouston@arglist.com>
158 * stime.c (scm_strftime): don't reset TZ if zone is an empty
159 string. append a "0" to the zone for TZ.
161 2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
163 * numbers.c (scm_logbit_p, scm_bit_extract): Reordered dispatch

178 (scm_tc16_flo, scm_tc_flo, scm_tc_dblr, scm_tc_dblc): Wrapped
179 deprecated code between #if (SCM_DEBUG_DEPRECATED == 0) #endif.
181 * fports.c (scm_fport_buffer_add), ports.c (scm_input_port_p,
182 scm_output_port_p), print.c (scm_get_print_state), validate.h
183 (SCM_VALIDATE_CHAR): Replace use of deprecated macros
184 SCM_INPORTP, SCM_OUTPORTP, SCM_ICHRP by SCM_INPUT_PORT_P,
185 SCM_OUTPUT_PORT_P, SCM_CHARP, respectively.
187 2000-05-14 Gary Houston <ghouston@arglist.com>
189 * stime.c (scm_strftime): if HAVE_TM_ZONE is not defined, hack the
190 TZ environment variable so that the %Z format returns the zone
191 from the input vector instead of the system default.
193 from Keisuke Nishida:
194 * fports.c (scm_setvbuf): minor docstring fix.
195 * ports.h (scm_generic_fgets): obsolete prototype deleted.
197 2000-05-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
199 * __scm.h: Added new section for debugging options.
201 (SCM_DEBUG_DEPRECATED): If 1, no deprecated code is included to
202 help developers to get rid of references to deprecated code.
204 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_UNEGFIXABLE,
205 SCM_FIXABLE, SCM_FLOBUFLEN): These macros are no longer provided
206 as part of the interface and are marked as deprecated in the
209 * numbers.c (scm_make_real, scm_make_complex): Inlined the
210 corresponding macros SCM_NEWREAL and SCM_NEWCOMPLEX,
213 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX, SCM_INEXP, SCM_CPLXP,
214 SCM_REAL, SCM_IMAG, SCM_REALPART, scm_makdbl, SCM_SINGP,
215 SCM_NO_BIGDIG, SCM_NUM2DBL, scm_dblproc): Deprecated.
217 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
219 * gc.h (scm_cell, SCM_CELL_WORD, SCM_CELL_OBJECT,
220 SCM_SET_CELL_WORD, SCM_SET_CELL_OBJECT): Scheme cells now consist
221 of two scm_bits_t values instead of two SCM values, because it is
222 legal for cell entries to hold values that are not scheme objects.
224 (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR):
225 Use SCM_SETC[AD]R to modify contents of pairs.
227 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
229 * numbers.c (IS_INF, isfinite): Added FIXME comment.
231 (scm_abs, scm_magnitude): Make these two independent of each
232 other. scm_abs now reports an error if given a complex argument.
234 (scm_istr2flo, scm_integer_p). Use SCM_REAL_VALUE instead of
235 SCM_REALPART if the object is known to be real.
237 (scm_init_numbers): No need to use SCM_NEWREAL macro for speed
240 * numbers.h (SCM_SINGP): Set to 0 instead of SCM_BOOL_F.
242 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>

248 gh_scm2doubles), hash.c (scm_hasher), ramap.c (scm_array_fill_int,
249 ramap_rp, scm_array_map_x), random.c (vector_scale,
250 vector_sum_squares), unif.c (scm_make_uve, scm_array_p,
251 scm_array_set_x): Use SCM_REAL_VALUE instead of SCM_REALPART if
252 the object is known to be real. Use SCM_COMPLEXP instead of
253 deprecated SCM_CPLXP. Use SCM_INEXACTP instead of deprecated
256 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
258 * numbers.c: No need to include unif.h.
260 (IS_INF): Returned to old test for now: x == x + 1 will not work
261 for large numbers due to rounding errors.
262 Thanks to Kalle Olavi Niemitalo.
264 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
266 * numbers.c (scm_divbigdig): Removed outdated comment.

275 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
277 * numbers.c (IS_INF): The new test is x == x + 1. The old test
278 x == x/2 did not work for zero values. Thanks to Han-Wen Nienhuys
281 (scm_number_to_string, scm_sum, scm_difference, scm_two_doubles,
282 scm_num2long, scm_num2long_long, scm_num2ulong): Reordered
285 2000-05-09 Marius Vollmer <mvo@zagadka.ping.de>
287 * scmsigs.c (take_signal): Execute SCM_ASYNC_TICK for SIGSEGV,
288 SIGILL and SIGBUS signals. These signals are not continuable and
289 must be handled for real right away.
291 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
293 * numbers.c (scm_zero_p, scm_positive_p, scm_negative_p,
294 scm_real_part, scm_imag_part, scm_magnitude,
295 scm_inexact_to_exact): Reordered dispatch sequence.
297 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
299 * feature.c: No need to include "libguile/smob.h"
301 (scm_loc_features, features, scm_add_feature, scm_init_feature):
302 Removed variable 'scm_loc_features' as a pointer to the SCM value
303 holding the features list. Using variable 'features' instead,
304 which holds the interned pair. Thus, SCM_SETCDR can be used
305 instead of pointer trickery.
307 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
309 * alist.c (scm_acons): Use SCM{_SET}?_CELL_OBJECT as long as a
310 cell is not known to be a valid pair.
312 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
314 * eval.c (ASRTSYNTAX, scm_m_body, scm_m_letrec1): Removed
315 ASRTSYNTAX. Using SCM_ASSYNT instead.
317 (scm_m_body): Don't create a redundant cons cell.
319 (scm_m_do): Removed redundant test 'bodycheck'.
321 (bodycheck): Removed.
323 * stacks.c (stack_depth, read_frame, read_frames): Removed
324 redundant calculation of size, minimized some variable scopes.
326 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
328 * pairs.c (scm_cons, scm_cons2): Use SCM{_SET}?_CELL_OBJECT as
329 long as a cell is not known to be a valid pair.
331 (scm_pair_p): Eliminated redundant SCM_IMP test.
333 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
335 * eval.c (scm_m_body, scm_macroexp, unmemocopy, scm_eval_args,
336 scm_deval_args): Eliminated redundant SCM_IMP tests.
338 * hashtab.c (scm_ihashx, scm_sloppy_assx, scm_delx_x), weaks.c
339 (scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
340 scm_make_doubly_weak_hash_table): Fixed critical sections.
341 Thanks to Keisuke Nishida.
343 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
345 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest):
346 Fixed some goto-related initialization bugs (introduced by me).
348 2000-05-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
350 * numbers.h (SCM_INUM0): Uses SCM_MAKINUM instead of SCM_PACK.
352 * dynl.c (dynl_obj, DYNL_OBJ, get_dynl_obj): Removed.
354 (DYNL_FILENAME, DYNL_HANDLE): Use SCM_CELL... macros instead of
357 (SET_DYNL_HANDLE): Added.
359 (scm_dynamic_object_p): Simplified.
361 (scm_dynamic_unlink, scm_dynamic_func): Changed comment. Deliver
362 better error message when accessing unlinked dynamic objects.
363 Eliminated call to get_dynl_obj.
365 2000-05-03 Marius Vollmer <mvo@zagadka.ping.de>
367 * scmsigs.c (orig_handlers) [!HAVE_SIGACTION]: Fix declaration to
368 be an array of function pointers instead of being a pointer to an
369 array returning function. Thanks to Kalle Olavi Niemitalo!
371 2000-05-03 Dirk Herrmann <D.Herrmann@tu-bs.de>
373 * numbers.c (scm_divbigbig, scm_divbigint), numbers.h
374 (scm_divbigbig, scm_divbigint): Don't return zero any more to
375 indicate that a division has a remainder, return SCM_UNDEFINED
376 instead. It is improbable that anyone actually used these
377 functions outside of numbers.c. For this reason and due to the
378 change in behaviour the functions are static now. Thus, if
379 surprisingly there are users of these functions they will at least
382 * numbers.c: Removed #ifdef SCM_BIGDIG #endif in those functions,
383 that already have a clean dispatch order. Note: SCM_BIGDIG is
386 * numbers.c (scm_inexact_p): Simplified.
388 * numbers.c (scm_num_eq_p, scm_less_p, scm_max, scm_min,
389 scm_product, scm_num2dbl, scm_angle): Reordered dispatch
390 sequence, thereby fixing some comparisons of SCM values with
393 * numbers.c (scm_divide): Division by zero of inums leads to an
394 error now. (Formerly, an infinite number was returned.)
396 Respect the fact, that scm_divbigbig does now return SCM_UNDEFINED
397 if a division has a remainder.
399 2000-05-02 Gary Houston <ghouston@arglist.com>
401 * Makefile.am (INCLUDES): add ${INCLTDL} (thanks to Tim Mooney).
403 2000-05-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
405 * numbers.c (scm_logtest, scm_division): Reordered dispatch
406 sequence, thereby fixing some comparisons of SCM values with
409 * numbers.h (scm_makdbl): Mark as deprecated at the point of
412 * eval.c (SCM_CEVAL, SCM_APPLY), gh_data.c (gh_double2scm,
413 gh_doubles2scm), numbers.c (scm_istr2flo, scm_max, scm_min,

418 (ramap_rp, scm_array_map_x), random.c (scm_random,
419 scm_random_uniform, scm_random_normal_vector_x, scm_random_exp),
420 struct.c (scm_struct_ref), unif.c (scm_array_to_list): Replace
421 call to scm_makdbl with a call to scm_make_real or
422 scm_make_complex, depending on whether the imaginary part is known

427 * scmsigs.c: fix the definition of orig_handlers for the case
428 that HAVE_SIGACTION is not defined (thanks to
429 Kalle Olavi Niemitalo).
431 * Makefile.am: remove include_HEADERS (was libguile.h)
432 libguile.h: moved to top level directory.
434 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
436 * numbers.c (SCM_SWAP): Moved to the top of the file to allow for
439 * numbers.c (scm_modulo, scm_gcd, scm_lcm, scm_logand, scm_logior,
440 scm_logxor): Reordered dispatch sequence, thereby fixing some
441 comparisons of SCM values with integer constants.

448 * numbers.c (scm_quotient, scm_remainder): Removed code that was
449 conditionally compiled based on BADIVSGNS. BADIVSGNS does not
450 occur anywhere else throughout guile.

455 * numbers.c (scm_remainder): Reordered dispatch sequence.
457 2000-04-25 Gary Houston <ghouston@arglist.com>

473 scm_dsubr, scm_init_iprocs): Removed.
475 * procs.h (SCM_SUBRF, SCM_DSUBRF): Access the cell words
476 directly instead of casting a cell to a C struct.
478 2000-04-22 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
480 Better modularization of GC extensions through new C level GC
483 * weaks.c (scm_weaks_prehistory): New function: Add

510 (scm_gc_sweep): Moved scanning of weak vectors to weaks.c.
511 (scm_igc): Moved initialization of scm_weak_vectors and the call
512 to scm_guardian_gc_init to respective module.
513 (scm_mark_weak_vector_spines): Moved to weaks.c;

538 the root build directory.
540 * numbers.c (scm_odd_p, scm_even_p): Use SCM_WRONG_TYPE_ARG

1042 * debug.c (scm_make_memoized), dynl.c (scm_dynamic_link): Smob
1043 data is of type scm_bits_t.
1045 2000-03-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
1047 * gdbint.c (gdb_maybe_valid_type_p), guardians.c (TCONC_EMPTYP,
1048 scm_guardian_zombify): Use SCM_EQ_P to compare SCM values.
1050 * guardians.c (GUARDIAN): Use SCM_CELL_WORD_1 for raw data.
1052 2000-03-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
1054 * ports.h (scm_port): Change type of stream member to scm_bits_t.
1056 * gdbint.c (unmark_port, remark_port), ports.c (scm_markstream),
1057 strports.c (st_resize_port, scm_mkstrport), vports (sf_flush,
1058 sf_write, sf_fill_input, sf_close, scm_make_soft_port): Since
1059 streams are now of type scm_bits_t, SCM streams have to be
1062 * ports.h (SCM_SETPTAB_ENTRY, SCM_SETSTREAM): Cast input to
1065 2000-03-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1067 * coop-defs.h (struct coop_t): Added `sto'-field again because of
1068 binary compatibility---let's remove it next time we alter some
1071 * coop.c (coop_quitting_p, coop_cond_create, coop_mutex_create,
1072 coop_mother, coop_child): New variables.
1073 (mother): New function.
1074 (coop_create): New thread spawning mechanism which uses a "mother
1075 thread". The "dummy" pthreads aren't healthy enough to give birth
1076 to new threads since Linux threads thinks they are asleep.
1078 * coop-defs.h (struct coop_t): Removed dummy_mutex.
1080 * coop-defs.h, coop-threads.c (struct coop_t): Eliminate
1081 `sto'-field when GUILE_PTHREAD_COMPAT is enabled.
1083 2000-03-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
1085 * arbiters.c (scm_make_arbiter), async.c (scm_async), dynwind.c
1086 (scm_internal_dynamic_wind): Smob data is always of type
1089 * arbiters.c (SCM_ARB_LOCKED, SCM_LOCK_ARB, SCM_UNLOCK_ARB):
1090 Access the locking information in cell entry 0 with
1091 SCM_{SET_}?CELL_WORD_0 instead of SCM_*CAR.
1093 * async.c (scm_run_asyncs): Use SCM_NULLP to test for the empty
1096 * dynwind.c (scm_dowinds): Use SCM_EQ_P to compare SCM values.
1098 * ports.h (SCM_PTAB_ENTRY, SCM_SETPTAB_ENTRY): Access the ptab
1099 entry data using SCM_{SET_}?CELL_WORD_1 instead of SCM_{SET}?CDR.
1101 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1103 * alist.c (scm_sloppy_assq, scm_assq), eq.c (scm_eq_p, scm_eqv_p,
1104 scm_equal_p), list.c (scm_ilength, scm_last_pair, scm_reverse,
1105 scm_sloppy_memq, scm_delq_x, scm_delq1_x), tags.h (SCM_UNBNDP):
1106 Don't use C operators == and != to compare SCM values, use
1109 * boolean.c (scm_boolean_p): Use SCM_BOOLP to determine whether a
1110 SCM value is equal to #t or #f.
1112 * eq.c (scm_eqv_p, scm_equal_p): Don't use SCM_CAR to access the
1113 cell type entry of non immediate objects of unknown type. Use
1114 SCM_CELL_TYPE instead.
1116 * gh_data.c (gh_scm2bool, gh_module_lookup), list.c
1117 (scm_sloppy_memv, scm_sloppy_member, scm_delv_x, scm_delete_x,
1118 scm_delv1_x, scm_delete1_x), scmsigs.c (scm_sigaction): Use
1119 SCM_FALSEP and SCM_TRUE_P to compare SCM values against #f and
1122 * list.c (scm_listify): Use SCM_UNBNDP to test for an unbound
1125 2000-03-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1127 * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread,
1128 scm_make_mutex, scm_make_condition_variable): Cast data to
1129 scm_bits_t in SCM_SET_CELL_WORD and SCM_NEWSMOB macros.
1131 * coop.c (coop_create): Set `specific' field, not `data' to NULL.
1133 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1135 * smob.h (SCM_NEWSMOB, SCM_NEWSMOB2, SCM_NEWSMOB3, SCM_SMOB_DATA,
1136 SCM_SET_SMOB_DATA, SCM_TC2SMOBNUM, SCM_SMOBNUM): To access smob
1137 data, use SCM_{SET_}?CELL_TYPE or SCM_{SET_}?WORD_[1-3].
1139 Note that this implies that smob data has always to be passed as
1140 values of type scm_bits_t.
1142 2000-03-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1144 * threads.c (scm_init_threads): Pass 0 size to scm_make_smob_type
1145 for scm_tc16_thread. As the current COOP threads are written, GC
1146 is not supposed to manage storage for threads.
1148 * error.c (scm_error): Don't try to throw an error if
1149 scm_gc_heap_lock is true.
1151 * coop.c (coop_finish): New function. Called at exit.
1152 (coop_aborthelp): Free thread structures when threads die.
1153 Finished LinuxThreads compatibility support => COOP threads now
1154 mesh with LinuxThreads.
1156 * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread):
1157 Changed SETCDR --> SET_CELL_WORD_1.
1159 * coop-threads.c (scheme_launch_thread): Set word 1 of handle to 0
1162 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1164 * boolean.h (SCM_TRUE_P): New macro.
1166 * boolean.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOLP), pairs.h
1167 (SCM_NULLP, SCM_NNULLP): Use SCM_EQ_P to compare SCM values.
1169 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1171 * continuations.h (SCM_CONTREGS, SCM_SET_CONTREGS): New macros to
1172 access continuation data.
1174 (SCM_SETJMPBUF): Deprecated. Use SCM_SET_CONTREGS instead.
1176 (SCM_JMPBUF, SCM_DYNENV, SCM_THROW_VALUE, SCM_BASE, SCM_SEQ,
1177 SCM_DFRAME): Use SCM_CONTREGS instead of SCM_CHARS to access
1180 * continuations.c (scm_make_cont), init.c (start_stack),
1181 root.c (scm_internal_cwdr): Use SCM_SET_CONTREGS instead of
1184 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1186 * symbols.h (SCM_LENGTH, SCM_SETLENGTH): Access the length field
1187 of strings and symbols by using SCM_{SET_}?CELL_WORD_0.
1189 (SCM_CHARS, SCM_UCHARS, SCM_SETCHARS): Use SCM_{SET_}?CELL_WORD_1
1190 to access the char * field of strings and symbols.
1192 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
1194 * gc.h (SCM_NEWCELL, SCM_NEWCELL2): Use SCM_SET_CELL_TYPE to set
1195 the type entry of a new cell. Added a comment about things to
1196 remember when updating the list of free cells.
1198 (SCM_FREEP, SCM_MARKEDP): Use SCM_CELL_TYPE to access the type
1201 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
1203 * pairs.h (SCM_CAR, SCM_CDR, SCM_SETCAR, SCM_SETCDR): Use
1204 SCM_CELL_OBJECT and SCM_SET_CELL_OBJECT. This change implies that
1205 with strict type checking enabled these macros will only work if
1206 given valid SCM parameters.
1208 (SCM_GCCDR): Moved to tags.h.
1210 * tags.h (SCM_GCCDR): Moved here from pairs.h.
1212 2000-03-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
1214 * tags.h (SCM2PTR, PTR2SCM): Moved to gc.h.
1216 * pairs.h (scm_cell, SCM_CELLPTR, SCM_CELL_WORD*, SCM_CELL_OBJECT*,
1217 SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*, SCM_CELL_TYPE,
1218 SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK, SCM_PTR_GT,
1219 SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC, SCM_NEWCELL,
1220 SCM_NEWCELL2): Moved to gc.h.
1222 (SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR, SCM_SETAND_CDR,
1223 SCM_SETOR_CAR, SCM_SETOR_CDR): Moved to gc.h. These names should
1224 be changed, though, since the macros are not only pair related.
1228 * gc.h (SCM2PTR, PTR2SCM, scm_cell, SCM_CELLPTR, SCM_CELL_WORD*,
1229 SCM_CELL_OBJECT*, SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*,
1230 SCM_CELL_TYPE, SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK,
1231 SCM_PTR_GT, SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC,
1232 SCM_NEWCELL, SCM_NEWCELL2, SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR,
1233 SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR): Moved here from
1236 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1238 * tags.h (SCM_STRICT_TYPING): New macro that, if defined,
1239 activates strict compile time type checking for variables of
1241 (SCM, SCM_PACK, SCM_UNPACK): Define according to whether
1242 SCM_STRICT_TYPING or SCM_VOIDP_TEST are defined.
1243 (SCM_EQ_P): Defined as a macro equivalent for eq?.
1245 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1247 * tags.h (SCM_POINTERS_MUNGED): Removed.
1249 * gc.c (scm_gc_sweep, init_heap_seg): Removed use of
1250 SCM_POINTERS_MUNGED, thus fixing some illegal casts to SCM.
1252 2000-03-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
1254 * pairs.h (SCM_CELL_OBJECT, SCM_CELL_OBJECT_[0-3],
1255 SCM_SET_CELL_OBJECT, SCM_SET_CELL_OBJECT_[0-3], SCM_CELL_TYPE,
1256 SCM_SET_CELL_TYPE): Added a set of low level macros for accessing
1258 (SCM_CELL_WORD_[0-3]): Renamed from the SCM_CELL_WORD[0-3].
1260 * procs.h, procs.c: Instead of SCM_{SET_}?CELL_WORD[12], use the
1261 newly introduced SCM_{SET_}?CELL_OBJECT_[12] macros.
1263 2000-03-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1265 * tags.h: Disabled definition of SCM_VOIDP_TEST.
1267 Defining SCM as void * introduces problems which haven't been
1268 handled yet. Developers who work with these issues can enable it
1269 in their working copies.
1271 Disabling this definition exposes a set of newly introduced and
1272 older misuses of types which causes warning messages during
1273 compilation. We'll fix this successively.
1275 * gc.c (scm_mark_locations): Changed * (SCM **) X --> * (SCM *) X
1276 in order to obtain a value of type SCM.
1277 (scm_cellp): Updated with new changes to scm_mark_locations.
1279 * continuations.h (SCM_SETJMPBUF): Cast second arg into SCM.
1281 * continuations.c (scm_make_cont): Removed cast of size_t into
1284 * symbols.h (SCM_SETCHARS): Cast second arg into SCM.
1286 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
1288 * numbers.h (SCM_SETNUMDIGS): Use SCM_BIGSIZEFIELD macro for
1289 shifting, not constant. Thanks to Dale P. Smith.
1291 * numbers.c (scm_sum, scm_difference): Don't test a SCM value
1292 for being less than zero. Decode it to a C value first. Again,
1295 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
1297 * numbers.h, ramap.c, struct.h, vectors.h: Don't use SCM2PTR for
1298 non scheme values. If raw data is stored in SCM variables, it has
1299 to be accessed using SCM_UNPACK until a better solution is found.
1301 2000-03-22 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1303 * tags.h (SCM_ECONSP, SCM_NECONSP): More corrections of
1304 pointer-arithmetic induced by the SCM_PACK/UNPACK change.
1306 * print.c (scm_iprin1): SCM_PACK/UNPACK corrections.
1308 * gc.c (scm_gc_sweep): SCM_PACK/UNPACK corrections.
1310 * eval.c (SCM_CEVAL, scm_unmemocar): SCM_PACK/UNPACK corrections.
1312 * dynwind.c (scm_swap_bindings): SCM_PACK/UNPACK corrections.
1314 * async.c, __scm.h: Removed lots of the old async click logic. It
1315 is possible to reinsert it by defining GUILE_OLD_ASYNC_CLICK in
1316 __scm.h. Let's try this out and dump the old code after the
1317 threads reorganization.
1318 (set-tick-rate, set-switch-rate): Conditionally removed.
1320 2000-03-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1322 * gc.c (scm_gc_mark): Bugfix 1: The recent SCM_PACK/UNPACK change
1323 made SCM values into pointers. This turned an arithmetic
1324 computation of the address of the vcell into a pointer-arithmetic
1325 one, thereby screwing up marking of structs.
1326 Bugfix 2: Removed incompletely introduced loop variable `j' used
1327 when protecting the tail array of a struct.
1329 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
1331 * struct.h (SCM_STRUCT_DATA): Don't cast SCM values to pointers.
1333 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
1335 * symbols.h, symbols.c (scm_strhash): Declare the string
1336 parameter as constant, since it is not modified.
1338 * symbols.c (scm_intern_obarray_soft,
1339 scm_sysintern0_no_module_lookup): Can now pass constant strings
1340 to scm_strhash without need for casting.
1342 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
1344 * vectors.h (SCM_VELTS, SCM_VELTS_AS_STACKITEMS): Don't cast SCM
1345 values to pointers. Use SCM2PTR instead.
1347 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
1349 * async.c (scm_set_tick_rate, scm_set_switch_rate): Don't unpack
1350 results of SCM_INUM.
1352 2000-03-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1354 * init.c (scm_boot_guile_1): Renamed GUILE_GC_TRIGGER_1 -->
1355 GUILE_MIN_YIELD_1, GUILE_GC_TRIGGER_2 --> GUILE_MIN_YIELD_2.
1356 GUILE_MIN_YIELD_X now take *positive* fractions of heap size.
1358 * gc.c, gc.h (SCM_MIN_YIELD_1, SCM_MIN_YIELD_2,
1359 min_yield_fraction, min_yield, adjust_min_yield): Renamed from
1360 SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2, gc_trigger_fraction,
1361 gc_trigger, adjust_gc_trigger.
1363 * gc.c (alloc_some_heap): Further improvement of minimal heap size
1365 (SCM_MAX): New macro.
1366 (scm_freelist_t): New field: collected_1. Previous amount of
1368 (gc_sweep_freelist_finish): Trigger based on two last values of
1369 freelist->collected to avoid unnecessary allocation due to
1371 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2):
1372 Adjusted to 45000 cells, 40% and 40%. Gives quick startup
1373 without extra heap allocation.
1375 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
1377 * numbers.h (SCM_MAKINUM): The parameter to SCM_MAKINUM should
1378 already be a C value. No need to unpack it.
1380 * numbers.c (scm_long_long2num): Cast the parameter to scm_bits_t
1381 if we know it fits into an inum.
1383 * ramap.c (ramap_rp): An scm_tc7_[ui]vect object does point to a
1384 field of long values. In contrast, SCM_VELTS accesses a field of
1387 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1389 * gc.c (scm_gc_stats): Inserted explanation of local_scm_mtrigger
1391 (scm_gc_yield_1): New variable: Holds previous yield. Used to
1392 make better judgements.
1393 (gc_sweep_freelist_finish): Inserted explanation of use of
1396 * print.h, stacks.h, options.c, options.h: Changed C++
1399 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
1401 * tags.h (SCM2PTR, PTR2SCM): Use SCM_PACK / SCM_UNPACK correctly.
1403 * numbers.h (SCM_INUMP, SCM_MAKINUM, SCM_INUM0, SCM_COMPLEX_REAL,
1404 SCM_COMPLEX_IMAG, SCM_NUMP, SCM_BDIGITS): Use SCM_PACK /
1405 SCM_UNPACK / SCM2PTR correctly.
1407 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1409 * gc.c (adjust_gc_trigger): Improved documentation.
1410 (alloc_some_heap): Since gc_trigger is used against
1411 freelist->collected, this is the value which should be used to
1412 predict minimum growth.
1414 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
1416 * eval.h: Fix mixup of packed/unpacked SCM values. (Thanks
1417 Thien-Thi Nguyen for the patch.)
1419 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
1421 * numbers.c (scm_ash): Fixed typing problems with the second
1422 parameter and added some documentation. (Thanks Thien-Thi Nguyen
1423 for indicating the problem.)
1425 2000-03-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1427 * gc.c, gc.h (scm_gc_yield): New variable.
1428 (adjust_gc_trigger): Use scm_gc_yield.
1429 (alloc_some_heap): Use scm_gc_yield instead of
1430 scm_gc_cells_collected.
1432 * coop-threads.c: Addd #include "root.h", #include "strings.h".
1434 * debug.c: Added #include "root.h". (Thanks to Thien-Thi Nguyen.)
1436 * gc.c (scm_gc_for_newcell, adjust_gc_trigger): Improved GC
1437 trigger adjustmeant: Take yield (freed cells) for all freelists
1439 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Tuned
1440 to 50000 cell heap with 45% trigger.
1441 (scm_gc_cells_collected): Reintroduced.
1442 (SCM_HEAP_SIZE): New macro.
1443 (scm_gc_sweep): Reintroduced correct computation of
1444 scm_cells_allocated.
1445 (scm_freelist_t): Corrected commentary for field `cluster_size':
1446 Clustersize counts objects, not cells; New member
1447 `clusters_allocated'.
1449 2000-03-19 Michael Livshin <mlivshin@bigfoot.com>
1451 * *.[hc]: add Emacs magic at the end of file, to ensure GNU
1454 2000-03-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1456 * threads.h: Added #include "libguile/throw.h". (Thanks to
1459 2000-03-18 Michael Livshin <mlivshin@bigfoot.com>
1461 * tags.h: (SCM_DOUBLE_CELLP, SCM_NDOUBLE_CELLP): new macros (bad
1462 names, anyone got any better ones?)
1464 * gc.h: (typedef struct scm_freelist_t) remove from here.
1466 * gc.c: (CELL_UP, CELL_DN) made these macros take additional
1467 parameter (the span).
1468 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK) new macros.
1469 (typedef struct scm_freelist_t) moved here from gc.h, it had no
1470 business being externally visible.
1471 (typedef struct scm_heap_seg_data_t) renamed from
1472 scm_heap_seg_data, to be style-compliant.
1473 (scm_mark_locations) if the possible pointer points to a
1474 double-cell, check that it's properly aligned.
1475 (init_heap_seg) align double-cells properly, work with the
1476 assumption that the segment size divides cleanly by cluster size.
1477 (round_to_cluster_size) new function.
1478 (alloc_some_heap, make_initial_segment) use round_to_cluster_size
1479 to satisfy the new init_heap_seg invariant.

1538 2000-03-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1540 * gc.c, gc.h: Cleanup of the change of 2000-03-15.
1541 Cluster sizes are now independent of GC trigger values.
1542 GUILE_GC_TRIGGER_n can now specify a relative trigger value:
1543 A negative integer gives fraction of total heap size in percent.
1544 (SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Default values set to -40.
1546 * init.c (scm_boot_guile_1): Introduced new variable
1547 GUILE_MAX_SEGMENT_SIZE; New environment variable names:
1548 GUILE_INIT_SEGMENT_SIZE_1, GUILE_GC_TRIGGER_1,
1549 GUILE_INIT_SEGMENT_SIZE_2, GUILE_GC_TRIGGER_2
1551 2000-03-16 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1553 * __scm.h (GC_FREE_SEGMENTS): Disable this until we have made
1554 freeing of segment work with the new GC scheme. (Thanks to
1555 Michael Livshin.) Oops, also happened to make GUILE_NEW_GC_SCHEME
1556 the default, but I'll let this change stay in CVS Guile since this
1557 code is not expected to contain serious bugs.
1559 2000-03-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1561 * gc.c, gc.h (scm_map_free_list): Define also if GUILE_DEBUG is
1563 (scm_free_list_length): New procedure (GUILE_DEBUG).
1564 Fixed a small but serious bug introduced by the previous change.
1566 * gc.c (scm_gc_sweep): Moved variable n_objects to inner sweep
1567 loop and declare as register.
1569 * gc.c (scm_gc_sweep): Sigh... forgot to clear private freelists
1572 Wed Mar 15 08:27:04 2000 Greg J. Badros <gjb@cs.washington.edu>
1574 * fluids.c: Docstring patch from Keisuke Nishida. Some
1575 reindentation, too, and a couple formals renamed. Should
1576 fluid-set! return UNSPECIFIED instead of a value?
1578 Wed Mar 15 08:24:58 2000 Greg J. Badros <gjb@cs.washington.edu>
1580 * Makefile.am: Separate out DOT_X_FILES and DOT_DOC_FILES, and
1581 generate the latter from the concrete listing of the former. Then
1582 make guile-procedures.txt depend on DOT_DOC_FILES instead of
1583 *.doc, so that rebuilding it works.
1585 Wed Mar 15 08:12:14 2000 Greg J. Badros <gjb@cs.washington.edu>
1587 * libguile.h: Include libguile/validate.h. Thanks Keisuke Nishida!
1589 * guile-snarf.awk.in: Replace docstring line-ending \n" and \n\n"
1590 with nothing and \n, respectively. Thanks Keisuke Nishida for
1591 noticing this problem.
1593 2000-03-15 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1595 * __scm.h (GUILE_NEW_GC_SCHEME): Define this if you want to test a
1596 new way of allocating heap. It makes Guile fast, but still
1599 * gc.c, gc.h, pairs.h, init.c: Implementation of a new way of
1600 allocating heap. The basic idea is to trigger GC every Nth
1601 allocated cell and grow heap when free list runs out. The scheme
1602 has been extended so that GC isn't triggered until all remaining
1603 cells are used. The implementation is also prepared for
1604 development in the direction of POSIX threads.
1606 * gc.c (SCM_EXPHEAP): In order to grow by a factor of 1.5,
1607 SCM_EXPHEAP should return half of the heap size.
1609 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1611 The following change to init.c is only enabled if Guile was
1612 configured with --enable-guile-debug.
1614 * init.c (scm_i_getenv_int): New function.
1615 (scm_boot_guile_1): Use the environment variables
1616 GUILE_INIT_HEAP_SIZE, GUILE_INIT_HEAP_SIZE2 to select heap size if
1617 they exist. (This may be replaced by a Scheme level mechanism in
1620 * objprop.c (s_scm_set_object_property_x): Use scm_assq instead of
1621 scm_assoc. (Thanks to Keisuke Nishida.)
1623 2000-03-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1625 * eval.c, lang.c, lang.h (scm_lisp_nil, scm_lisp_t): Renamed from
1626 scm_nil, scm_t. (Thanks to Keisuke Nishida.)
1628 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1630 * init.c (scm_boot_guile_1): Use same initial segment size for
1631 1-word and 2-word segments. Having the smaller size causes Guile
1632 to GC too often. Obviously something needs to be done to allow
1633 for a smaller 2-word segment without this to happen. (The amount
1634 of heap for each type should be automatically adapted to the
1635 application somehow.)
1637 [Almost all of these changes should be documented in the NEWS
1640 * gc.h (scm_freelist_t): New type.
1642 * pairs.h (SCM_NEWCELL, SCM_NEWCELL2): Use new style freelists.
1644 * gc.c (SCM_INIT_HEAP_SIZE): Changed from 32768 --> 40000 so that
1645 all of Guile basics fits into one segment and there suitable room
1647 (SCM_EXPHEAP): Now takes an argument. Grow by a factor of 1.5
1649 (scm_freelist, scm_freelist2): Now of type scm_freelist_t.
1650 Freelists now contains information about object span, cells
1651 collected and amount of cells in heap segments belonging to the
1653 (scm_heap_size, scm_gc_cells_collected): Removed.
1655 * init.c (scm_boot_guile_1): Make 2-word segment 8K (512 cells).
1657 * Makefile.am (libguile_la_LDFLAGS): Bumped library version
1660 * __scm.h eq.c, eval.c, gc.c, gc.h, gh_data, hash.c, numbers.c,
1661 numbers.h, objects.c, ramap.c, random.c, unif.c, unif.h: Extensive
1662 rewrite of handling of real and complex numbers.
1663 (SCM_FLOATS, SCM_SINGLES): These #ifdef conditionals have been
1664 removed along with the support for floats. (Float vectors are
1667 * tags.h (scm_tcs_bignums): Removed.
1668 (scm_tc16_bigpos, scm_tc16_bigneg): Replaced by scm_tc16_big.
1669 Use SCM_BIGSIGN(x) to test for sign!
1670 (scm_tc16_big): The new bignum type.
1671 (SCM_REAL_PART, SCM_IMAG_PART): Removed.
1673 * numbers.h (SCM_BIGSIGN): Sign moved to bit 16.
1674 (scm_makdbl): Deprecated.
1675 (SCM_NEWREAL, SCM_NEWCOMPLEX): New macros.
1676 (SCM_SINGP): Deprecated.
1678 (SCM_INEXP, SCM_CPLXP): Deprecated.
1679 (SCM_INEXACTP, SCM_COMPLEXP): New macros.
1680 (SCM_COMPLEX_REAL, SCM_COMPLEX_IMAG): Renamed from
1681 SCM_REAL, SCM_IMAG (and now only valid for complex numbers).
1682 (SCM_REAL, SCM_IMAG): New, *deprecated*, selectors which work both
1683 for doubles and complex numbers.
1684 (SCM_REAL_VALUE): New selector for doubles.
1685 (scm_double_t, scm_complex_t): New types.
1688 * numbers.c (scm_floprint, scm_floequal): Removed.
1689 (scm_print_real, scm_print_complex, scm_real_equalp,
1690 scm_complex_equalp): New functions.
1692 * unif.c (scm_makflo): Removed.
1694 * smob.h (SCM_SMOB_PREDICATE): New macro.
1695 (SCM_NEWSMOB2, SCM_RETURN_NEWSMOB2, SCM_NEWSMOB3,
1696 SCM_RETURN_NEWSMOB3): New macros.
1698 1999-11-21 Michael Livshin <mlivshin@bigfoot.com>
1700 The following changes implement primitive support for double cells
1701 (i.e. four-word cells) and change the representation of some
1702 things to multi-cells instead of cons+malloc. (Applied and
1705 * pairs.h (SCM_NEWCELL2): double-cell variants of SCM_NEWCELL.
1706 (SCM_CELL_WORD, SCM_CELL_WORDLOC, SCM_SET_CELL_WORD): primitive
1707 multi-cell access macros (used by the ones below).
1708 (SCM_CELL_WORD[0-3], SCM_SET_CELL_WORD[0-3]): multi-cell access
1711 * gc.c (scm_freelist2): multi-cell freelists.
1712 (inner_map_free_list): map_free_list, parameterized on ncells.
1713 "nn cells in segment mm" was misleading for ncells > 1; changed to
1714 "objects". still print cells too, though.
1715 (scm_map_free_list): rewritten using inner_map_free_list.
1716 (scm_check_freelist): get freelist as parameter, since now we have
1718 (scm_debug_newcell2): multi-cell variants of
1720 (scm_gc_for_newcell): take ncells and freelist pointer as
1722 (scm_gc_mark): add case for tc7_pws (procedures with setters are
1724 (scm_gc_sweep): don't free the float data, since it's not malloced
1726 (init_heap_seg): didn't understand what n_new_objects stood for,
1727 so changed to n_new_cells.
1728 (make_initial_segment): new function, makes an initial segment
1729 according to given ncells.
1730 (scm_init_storage): call make_initial_segment, for ncells={1,2,3}.
1732 * numbers.c (scm_makdbl): no malloc'ing needed, so the
1733 {DEFER,ALLOW}_INTS thing removed.
1735 * numbers.h (struct scm_dbl): changed to represent a double cell,
1736 with the number in the second half.
1738 * dynwind.c: changed the wind-guards representation to double
1741 * procs.c, procs.h: changed the procedure-with-setter representation
1744 * async.c, async.h: made async representation a double cell.
1746 * dynl.c: made dynamic_obj representation a double cell.
1748 2000-03-13 Gary Houston <ghouston@arglist.com>
1750 * ports.c (flush_void_port): renamed to flush_port_default.
1751 (end_input_void_port): renamed to end_input_default.
1753 * init.c (scm_standard_stream_to_port): create a void port instead
1754 of opening /dev/null if the standard file descriptors are bad.
1755 advantages: no portability problems, doesn't waste a file descriptor,
1756 simplifies the code (thanks to Marius for the idea).
1758 * vports.c (s_scm_make_soft_port): call scm_port_non_buffer.
1760 * void ports: make reading from a void port give EOF instead of
1762 * ports.c (s_scm_sys_make_void_port): modified docstring.
1763 (fill_input_void_port): new proc.
1764 (scm_init_ports): set up fill_input_void_port.
1765 * ports.c (scm_port_non_buffer): new proc.
1766 (scm_void_port): call scm_port_non_buffer.
1768 * fports.c (scm_setvbuf): docstring: remove the fcntl documentation
1769 which was incorrectly appended.
1771 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1773 * guile-doc-snarf.in: Don't use absolute path for `sed'. (Note
1774 that we can't use autoconf for this. Autoconf itself relies on
1775 the existence of `sed' somewhere on your path.) (Thanks to Dirk
1778 2000-03-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1780 * Makefile.am (libguile_la_SOURCES): Moved iselect.c here from
1781 EXTRA_libguile_la_SOURCES.
1783 * iselect.h: Always declare scm_internal_select.
1785 * iselect.c (scm_internal_select): Added SCM_ASYNC_TICK at the
1786 end. Also let scm_internal_select be a real function also when
1789 * __scm.h (SCM_TICK): Oops! Forgot to put SCM_ASYNC_TICK here...
1791 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1793 * __scm.h (SCM_ALLOW_INTS, SCM_REALLOW_INTS): Removed call to
1794 SCM_ASYNC_TICK. (This is a preparation for POSIX threads support,
1795 and kind of an experiment: Will this cause problems?)
1797 Sun Mar 12 13:26:30 2000 Greg J. Badros <gjb@cs.washington.edu>
1799 * Makefile.am: Added *.doc to DISTCLEANFILES.
1801 2000-03-12 Gary Houston <ghouston@arglist.com>
1803 * fports.c (scm_fdes_to_port): call fcntl F_GETFL to test that
1804 the fdes is valid before doing anything else. check that
1805 the file descriptor supports the modes required.
1806 (scm_fport_buffer_add): don't throw an error if fstat doesn't
1807 work: just use the default buffer size.
1809 * throw.c: change an outdated comment about scm_internal_catch
1810 BODY: it doesn't take a jumpbuf arg.
1812 * init.c (scm_standard_stream_to_port): install a handler in case
1813 scm_fdes_to_port throws an error. don't check here whether the
1814 file descriptor is valid, since scm_fdes_to_port will do that.
1815 set the revealed count depending on whether the port got the
1816 standard file descriptor.
1817 (stream_body_data): new type.
1818 (stream_body, stream_handler): new procs.
1820 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1822 * stacks.c, stacks.h, struct.c, tags.h, unif.c (scm_bits_t):
1823 Renamed from SCMWORD.
1825 * tags.h (SCM_NCELLP): Removed (SCMWORD).
1827 * arbiters.c (SCM_ARB_LOCKED): Use SCM_UNPACK_CAR.
1829 * async.c, boolean.h, debug.c, dynl.c, dynwind.c, eval.c, eval.h,
1830 feature.h, filesys.h, fluids.h, fports.c, fports.h, gc.c, gc.h,

1836 weaks.h (SCM_PACK, SCM_UNPACK, SCM_UNPACK_CAR): Renamed from
1837 SCM_ASSCM, SCM_ASWORD, SCM_CARW).
1839 * numbers.h (SCM_SRS, SCM_INUM): Corrected SCM_ASSCM/ASWORD fixes.
1841 * alist.c, eval.c, net_db.c, posix.c, print.c, snarf.h, struct.c,
1842 tags.h: Fixed copyright notices.
1844 * struct.c, coop-threads.c: SCM_ASSCM/ASWORD fixes.
1846 2000-03-12 Marius Vollmer <mvo@zagadka.ping.de>
1848 * init.c (scm_standard_stream_to_port): Check whether the file
1849 descriptor is valid and substitute "/dev/null" when not.
1851 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1853 * coop-defs.h (struct timespec): Conditionally defined.
1855 * coop.c (coop_condition_variable_timed_wait_mutex): Use ETIMEDOUT
1858 * readline.c (match_paren): Bugfix: First arg to select is not
1859 number of descriptors but the number of the highest descriptor +
1862 This is a preliminary attempt at a cleanup of the threads support
1863 code. It moves things to better places, makes arguments more
1864 consistent with the POSIX API (which is used in GNOME's glib), and
1865 adds new functionality.
1867 * readline.c (scm_init_readline): Added new arg to scm_init_mutex.
1869 * coop-defs.h (scm_mutex_trylock): New macro: alias for
1871 (scm_cond_init): Changed definition to
1872 coop_new_condition_variable_init.
1874 * coop.c: #include <errno.h>
1875 (coop_timeout_qinsert): Moved here from iselect.c
1876 (coop_new_mutex_init, coop_new_condition_variable_init): New
1877 functions. The strange names are temporary. Use scm_mutex_init
1878 and scm_cond_init instead.
1879 (coop_mutex_trylock): New function. Uses errno.h:EBUSY. errno.h
1880 is ANSI C, but should we check for individual error codes in
1882 (coop_condition_variable_timed_wait_mutex): New function.
1883 (coop_key_create, coop_setspecific, coop_getspecific,
1884 coop_key_delete): New functions.
1886 * iselect.c (coop_timout_qinsert): Moved to coop.c
1888 2000-03-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1890 * pairs.h (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR,
1891 SCM_SETOR_CDR): Corrected SCM_ASSCM/WORD fixes.
1893 * tags.h (SCM_VOIDP_TEST): Renamed from VOIDP_TEST.
1896 * objects.h (SCM_CLASS_FLAGS, SCM_OBJ_CLASS_FLAGS,
1897 SCM_SET_CLASS_INSTANCE_SIZE), struct.h (SCM_STRUCT_VTABLE_DATA),
1898 proc.h (SCM_CLOSCAR): SCM_ASSCM/WORD fixes.
1900 * eval.c (scm_lookupcar1): Inserted SCM_ASWORD in expressions
1903 2000-03-11 Dale P. Smith <dpsm@en.com>, applied by Greg J. Badros, <gjb@cs.washington.edu>
1905 * numbers.c (scm_copy_big_dec, scm_copy_smaller, scm_big_ior,
1906 scm_big_xor, scm_big_and, scm_big_test): Added new lowlevel bignum
1907 logical functions from SCM.
1909 (logand, logior, logxor, logtest, logbit?): Extended scheme
1910 logical functions to use bignums from SCM.
1912 (lognot): Removed call to `SCM_VALIDATE_INUM' that prevented
1913 lognot from using bignums.
1915 Thu Mar 9 11:33:25 2000 Greg J. Badros <gjb@cs.washington.edu>
1917 * vectors.h (SCM_VELTS_AS_STACKITEMS): Added this macro to help in
1918 eliminating some warnings.
1920 * unif.c, strports.c, print.c, options.c: Fix some warnings on
1923 * gc.c, gc.h: Added scm_return_first_int(), and added comment re:
1924 what the scm_return_first* functions do.
1926 2000-03-09 Han-Wen Nienhuys <hanwen@cs.uu.nl>, applied by Greg J. Badros, <gjb@cs.washington.edu>
1928 * libguile/*.[ch]: make a distinction between SCM as a generic
1929 name for a Scheme object (now a void*), and SCM as 32 bit word for
1930 storing tags and immediates (now a long int). Introduced
1931 SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
1932 code in the process: arbiter.c (use macros), unif.c (scm_array_p),
1934 Wed Mar 8 10:15:59 2000 Greg J. Badros <gjb@cs.washington.edu>
1936 * numbers.c: Use SCM_VALIDATE_LONG_COPY, and longs, not ints, in
1937 various logXXX primitives. Thanks Eric Moore!
1939 Tue Mar 7 08:05:22 2000 Greg J. Badros <gjb@cs.washington.edu>
1941 * run-test, remaining-docs-needed: Added these scripts. The
1942 second one is only temporary until the docstring additions are
1943 complete. run-test may best live on, but is here mostly for
1944 convenience and awareness for now.
1946 * hash.c: Docs, minor cleanup patch from Dirk Herrman.
1948 Thu Mar 2 16:06:58 2000 Greg J. Badros <gjb@cs.washington.edu>
1950 * error.h, error.c: Added `scm_wrong_type_arg_msg' to support
1951 displaying the expected type. Use SCM_LISTn in a couple places
1952 instead of scm_cons-ing by hand.
1954 * __scm.h: Added SCM_ASSERT_TYPE macro.
1956 * validate.h, scm_validate.h: Added the former, as a renamed
1957 version of the latter with SCM_ASSERT_TYPE used in
1958 SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
1960 * Makefile.am: Rename scm_validate.h to validate.h.
1962 * *.c, *.h: Include validate.h, not scm_validate.h (old name's
1963 prefix was superfluous).
1965 Thu Mar 2 15:33:12 2000 Greg J. Badros <gjb@cs.washington.edu>
1967 * hashtab.c: Improved documentation for lots of functions. Added
1968 handwritten docs for `hash-fold'.
1970 Thu Mar 2 15:13:25 2000 Greg J. Badros <gjb@cs.washington.edu>
1972 * list.c: Added hand-written docs for `del{q,v,ete}1!'.
1974 Thu Mar 2 12:38:30 2000 Greg J. Badros <gjb@cs.washington.edu>
1976 * list.c: Moved append docs to append! Thanks Dirk Hermann. Also,
1977 added append docs from R4RS.
1979 * strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
1980 Thanks Dirk Hermann!
1982 * chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
1983 deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR. Thanks Dirk Hermann!
1985 * *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
1986 Drop use of SCM_P for function prototypes... assume an ANSI C
1987 compiler. Thanks Dirk Hermann!
1989 Sat Feb 19 12:20:12 2000 Greg J. Badros <gjb@cs.washington.edu>
1991 * ports.c: Made `set-port-column!' and `set-port-line!' each
1992 return SCM_UNSPECIFIED instead of a (not-scheme-object) integer
1993 that caused a seg fault. Also fixed `set-port-column!'s
1994 docstring. Thanks Han-Wen Nienhuys for finding the bug!
1996 Sun Feb 13 19:11:42 2000 Greg J. Badros <gjb@cs.washington.edu>
1998 * arbiters.c, eq.c, gc.c, guardians.c, list.c, ports.c, print.c,
1999 regex-posix.c, scmsigs.c, stime.c, strings.c, variable.c, stime.c,
2000 strings.c, variable.c: Added lots of documentation, cleaned up
2001 some existing documentation. Occasionally changed formal params
2002 to match docs. Also folded an #ifdef into the inners of a
2003 primitive instead of having two copies of the primitive
2004 (`get-internal-real-time', from stime.c)
2006 Sun Feb 13 18:12:19 2000 Greg J. Badros <gjb@cs.washington.edu>
2008 * ports.c: Added docs for primitives missing them. Written by
2011 Sun Feb 13 09:40:36 2000 Greg J. Badros <gjb@cs.washington.edu>
2013 * guile-doc-snarf.in: Use ${AWK} -f guile-func-name-check, not
2014 just execing guile-func-name-check. Thanks Michael Livshin!
2016 Thu Feb 10 11:43:23 2000 Greg J. Badros <gjb@cs.washington.edu>
2018 * guile-snarf.awk.in: Tweak to work with Sun/HP awk, removed some
2019 dead code. Patch from Michael Livshin.
2021 * guile-doc-snarf.in: Tweak to work with Sun/HP sh. Patch from
2024 2000-02-09 Gary Houston <ghouston@arglist.com>
2026 * init.c (scm_init_standard_ports): when stdout is a tty, make the
2027 current-output-port unbuffered by default. this is less confusing
2028 for interactive use. it was line-buffered because of a
2029 performance problem with unbuffered ports, but I think it will be
2032 2000-02-08 Gary Houston <ghouston@arglist.com>
2034 * __scm.h: don't define long_long or ulong_long if HAVE_LONG_LONGS
2037 * stime.c (scm_localtime, scm_mktime): if neither HAVE_TM_ZONE nor
2038 HAVE_TZNAME are defined, use an empty string instead of giving two
2039 spurious compile-time errors.
2041 Tue Feb 8 13:57:46 2000 Greg J. Badros <gjb@cs.washington.edu>
2043 * ports.c: Doc patches from Richard Kim. Pasted from MIT Scheme.
2046 Mon Feb 7 09:07:31 2000 Greg J. Badros <gjb@cs.washington.edu>
2048 * macros.c: Doc patches from Richard Kim. Pasted from scm.texi.
2050 Sun Feb 6 20:26:21 2000 Greg J. Badros <gjb@cs.washington.edu>
2052 * pairs.c: Doc patches from Richard Kim. Pasted from MIT Scheme
2053 (which is GNU GPL'd).
2055 2000-01-31 Gary Houston <ghouston@arglist.com>
2057 * strings.h: don't use SCM_P. don't include <string.h>.
2058 * error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>.
2060 * strings.c (scm_string_ref): make the 2nd argument compulsory.
2061 previously it defaulted to zero for no good reason that I can see.
2062 use a local variable for SCM_INUM (k). replace
2063 SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
2065 (scm_makfromstr): cosmetic changes.
2067 (scm_string): Accept only chars in the list, not strings, for
2068 conformance to R5RS (particularly for list->string, which is
2069 supposed to be the inverse of string->list.) remove
2070 SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
2071 scm_makstr handles the cell allocation. when reporting wrong-type
2072 arg, don't report the position as 1.
2074 * posix.c (scm_init_posix): intern PIPE_BUF if it's defined.
2076 2000-01-29 Gary Houston <ghouston@arglist.com>
2078 * posix.c (scm_pipe): rewrote the docstring.
2080 * filesys.c (scm_select, retrieve_select_type, get_element,
2081 fill_select_type, set_element): modified so that Scheme
2082 "select" tests port buffers for the ability to provide input
2083 or accept output. Previously only the underlying file descriptors
2084 were checked. Rewrote the docstring.
2086 Thu Jan 27 10:14:25 2000 Greg J. Badros <gjb@cs.washington.edu>
2088 * vectors.c, symbols.c, strorder.c: Documentation cut and pasted
2089 from Gregg Reynolds. Thanks Gregg!
2091 Thu Jan 27 09:59:38 2000 Greg J. Badros <gjb@cs.washington.edu>
2093 * strop.c (scm_i_index): Obfuscated commented-out SCM_DEFINE by
2094 adding "x" prefix to the line so that guile-func-name-check
2095 doesn't complain unnecessarily.
2097 Wed Jan 26 17:33:52 2000 Greg J. Badros <gjb@cs.washington.edu>
2099 * throw.c: Factor out an #ifdef/#else/#endif choice more finely
2100 for maintainability.
2102 * strop.c: Documentation added by Gregg A. Reynolds. Pasted in
2105 Wed Jan 26 10:02:11 2000 Greg J. Badros <gjb@cs.washington.edu>
2107 * tag.c: Added doc for `tag', but mark as deprecated since Mikael
2108 suggests removing tag.c altogether (and using a new `class-of'
2111 * strings.c: Added documentation from Gregg A. Reynolds. Edited
2112 a bit by me to use FOO instead of @var{foo} and to have the
2113 summary come before preconditions on input. Also dropped trailing
2116 * gsubr.c: Do not use SCM_DEFINE for `gsubr-apply'. Register the
2117 function with scm_make_subr_opt w/ last arg of 0 so it is not
2118 visible at the Scheme level. Mikael says that this is the right
2119 thing because the first arg to the proc is the guts of a compiled
2120 closure and shouldn't be exposed to the Scheme level.
2122 Tue Jan 25 17:15:47 2000 Greg J. Badros <gjb@cs.washington.edu>
2124 * sort.c: typo in comment fixed.
2126 * keywords.c: Added documentation.
2128 * guardians.c: Added documentation (could be better).
2130 * gc.c: Added docs for gc-set-debug-check-freelist.
2132 * eq.c: Added docs for eq?, eqv? equal? abridged from R4RS.
2134 * boolean.c: Added docs for `not', `boolean?' (by hand).
2136 Tue Jan 25 13:28:56 2000 Greg J. Badros <gjb@cs.washington.edu>
2138 * random.c: Added documentation, from SLIB page:
2139 http://angela.ctrl-c.liu.se/~calle/scheme/slib_toc.html
2141 Mon Jan 24 17:50:20 2000 Greg J. Badros <gjb@cs.washington.edu>
2143 * variable.c, version.c: Added documentation, written by hand
2144 since I could not find anything already written that was
2147 2000-01-23 Gary Houston <ghouston@arglist.com>
2149 * filesys.c (scm_chown): omit port/fdes support if HAVE_FCHOWN is
2150 not defined (thanks to Richard Y. Kim).
2152 Thu Jan 20 13:00:38 2000 Greg J. Badros <gjb@cs.washington.edu>
2154 * Makefile.in: Removed, this is auto-generated.
2156 Thu Jan 20 11:33:47 2000 Dirk Hermann <dirk@ida.ing.tu-bs.de> --applied 01/20/00 gjb
2158 * list.c: Put some variable initialization code at the point of
2159 declaration; Added a comment for list*; Formatting changes.
2161 * load.c: use SCM_NNULLP to make sure the end of a list is not
2164 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2166 * backtrace.c (scm_display_error_message): Bugfix: Don't use
2167 result of scm_list_p as C boolean.
2168 (scm_display_error_message, scm_set_print_params_x): Use new
2169 validation macros. (Thanks to Dirk Herrmann.)
2171 * net_db.c (scm_resolv_error): Cast result from hstrerror.
2173 * strports.c (st_end_input): Inserted parenthesis to get operator
2176 * list.h (scm_init_list): Removed SCM_P around prototypes.
2178 * fports.c, list.c, numbers.c, ports.c, stime.c, symbols.c,
2179 filesys.c, posix.c: Converted docstrings to ANSI C format and
2180 escaped " occurring inside string literals.
2182 Tue Jan 18 13:21:08 2000 Mikael Djurfeldt <mdj@r11n07-s.pdc.kth.se>
2184 * posix.c (scm_mknod): Escape " occuring inside docstring.
2186 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2188 * alist.c, chars.c, debug.c, dynl.c, dynwind.c, error.c, eval.c,
2189 evalext.c, filesys.c, gc.c, hash.c, hashtab.c, ioext.c,
2190 keywords.c, list.c, load.c, macros.c, net_db.c, numbers.c,
2191 objprop.c, ports.c, posix.c, print.c, procprop.c, procs.c,
2192 ramap.c, regex-posix.c, root.c, scmsigs.c, simpos.c, socket.c,
2193 stacks.c, stime.c, strings.c, strop.c, strports.c, struct.c,
2194 symbols.c, throw.c, unif.c, vectors.c, version.c, vports.c,
2195 weaks.c: Converted docstrings to ANSI C format.
2197 * filesys.c (scm_chmod), simpos.c (scm_system), version
2198 (scm_version), vports (scm_make_soft_port): Escape " occuring
2201 Mon Jan 17 11:41:22 2000 Greg J. Badros <gjb@cs.washington.edu>
2203 * scm_validate.h: Added SCM_VALIDATE_ULONG_COPY,
2204 SCM_VALIDATE_LONG_COPY
2206 * numbers.c: Use SCM_VALIDATE_ULONG_COPY, instead of
2207 SCM_VALIDATE_INUM_COPY to let bigger numbers be used. Rename a
2208 couple of formal arguments (and fix their uses) to make arguments
2209 match the documentation.
2211 2000-01-14 <mstachow@alum.mit.edu>
2213 * Makefile.am: Augment path when running guile-doc-snarf so
2214 guile-func-name-check is found.
2216 Fri Jan 14 09:34:55 2000 Greg J. Badros <gjb@cs.washington.edu>
2218 * scm_validate.h (SCM_NUM2LONG_DEF): Fix this macro to just use
2219 def, not SCM_MAKINUM(def); thanks Janis Bzerins!
2221 Wed Jan 12 00:06:53 2000 Greg J. Badros <gjb@cs.washington.edu>
2223 * net_db.c (s_scm_inet_makeaddr): Use SCM_NUM2ULONG since that's
2224 the way guile-1.3.4 worked, but #if 0 out the version using
2225 SCM_VALIDATE_INUM_COPY for stricter testing.
2227 Tue Jan 11 18:24:18 2000 Greg J. Badros <gjb@cs.washington.edu>
2229 * guile-doc-snarf.in: Use new $fullfilename for running
2230 guile-func-name-check, and put "$fullfilename" and "$filename" in
2231 quotes at uses to make sure re-splitting on whitespace does not
2232 occur (so filenames w/ embedded whitespace would work okay, though
2233 I sure hope we never have to deal with that! :-) ). Thanks to
2234 Mikael for pointing out the source_dir != build_dir was broken.
2236 Tue Jan 11 17:42:40 2000 Greg J. Badros <gjb@cs.washington.edu>
2238 * scm_validate.h: Added SCM_NUM2LONG_DEF macro. Make
2239 SCM_OUT_OF_RANGE use SCM_MAKINUM, not scm_long2num. Added
2240 SCM_COERCE_ROSTRING macro. Added SCM_VALIDATE_NONEMPTYLIST
2241 macro. Fix SCM_VALIDATE_STRINGORSUBSTR macro to not use SLOPPY
2244 * ports.c (scm_port_closed_p): Validate that the arg is a PORT,
2245 then return whether it's an open port (was validating that it was
2246 an open port -- this was a bug I introduced back in December, but
2247 my careful reading of diffs caught it).
2249 * numbers.c: Recombine the two conditional-compilation paths for
2250 all the log* primitives -- they were split based on #ifndef
2251 scm_long2num; factored out a SCM_LOGOP_RETURN macro, and fixed
2252 some bugs and inconsistencies in the two sets of implementations.
2253 (scm_lognot) Fixed *atrocious* re-use of a SCM as an integer!
2255 * ioext.c: Use SCM_ASSERT_RANGE in a couple places, and
2256 SCM_VALIDATE_INUM_COPY once where it should've been used.
2258 * fluids.c (scm_internal_with_fluids): Use
2259 SCM_VALIDATE_LIST_COPYLEN.
2261 * filesys.c: Use SCM_NUM2LONG instead of SCM_VALIDATE_INUM_COPY;
2262 this is questionable as it relaxes type safety, but other changes
2263 were useful and all SCM_NUM2LONG's should probably be
2264 revisited. Use SCM_OUT_OF_RANGE, SCM_WRONG_TYPE_ARG.
2266 * evalext.c: line-break change on 1 line.
2268 * eval.c (nconc2last): Takes a non-empty list as its first
2269 argument, not just a list.
2271 * dynl.c: Use new SCM_COERCE_ROSTRING macro.
2273 Tue Jan 11 15:44:23 2000 Greg J. Badros <gjb@cs.washington.edu>
2275 * dynl.c, feature.c, filesys.c, fports.c, list.c, load.c,
2276 net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
2279 * symbols.c (scm_sysintern0): Fixed the function name in a
2280 scm_misc_error invocation.
2282 * print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
2283 use scm_return_first to ward off latent GC bug that Mikael caught.
2285 * async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
2286 used before but should've been.
2288 2000-01-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2290 * snarf.h (SCM_PROC1): Replaced SCM (*) (...) with
2291 SCM_FUNC_CAST_ARBITRARY_ARGS.
2293 Tue Jan 11 13:44:07 2000 Greg J. Badros <gjb@cs.washington.edu>
2295 * guile-func-name-check.in: Added this script to statically check
2296 #define FUNC_NAME, #undef FUNC_NAME in the source.
2298 * sort.c, posix.c: Fix #undef FUNC_NAME lines to not have trailing
2299 redundant comment, semicolon; caught by new guile-func-name-check
2302 * debug.c: Fix mistaken #define FUNC_NAME for scm_make_iloc.
2303 Caught by new guile-func-name-check-script.
2305 * Makefile.am: Added guile-func-name-check to bin_SCRIPTS
2307 * ramap.c: Fix #if 0'd out code to be syntactically acceptable to
2308 guile-func-name-check.
2310 * guile-doc-snarf.in: Run guile-func-name-check on the file before
2313 Tue Jan 11 11:31:10 2000 Greg J. Badros <gjb@cs.washington.edu>
2315 * fports.c, ports.c, ports.h, strports.c, vports.c: Make write
2316 port function take const void*, not void*.
2318 Tue Jan 11 11:18:07 2000 Greg J. Badros <gjb@cs.washington.edu>
2320 * scm_validate.h, chars.c, ports.c, print.c, read.c, strings.c,
2321 strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
2322 SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY. Change made for
2323 consistency with the other macros dealing with immediate
2324 characters. (Similar to INT -> INUM change a week or so ago).
2326 Tue Jan 11 10:41:46 2000 Greg J. Badros <gjb@cs.washington.edu>
2328 * dynl.c, error.c, eval.c, feature.c, filesys.c, fports.c, list.c, load.c,
2329 net_db.c, read.c, socket.c: Update error messages to use ~A for
2330 %s, ~S for %S to work with new `simple-format' format and be
2331 standardized better.
2333 * print.h, print.c (scm_simple_format): Added `simple-format'
2334 primitive. It's the old scm_display_error, with ARGS now a rest
2335 parameter, and the destination first instead of last (and a couple
2336 new capabilities inspired by `format' -- #t as destination means
2337 current-output-port, #f means return the formatted text as a
2340 * gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
2342 * backtrace.c (scm_display_error_message): Rewrote to use
2343 scm_simple_format() procedure.
2345 * __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
2347 2000-01-09 Marius Vollmer <mvo@zagadka.ping.de>
2349 Finally applied the libltdl patch from Thomas Tanner, with slight
2352 * DYNAMIC-LINKING: Removed because it is obsolete.
2353 * dynl.c: Use ANSI prototypes.
2354 (sysdep_dynl_link): Use lt_dlopenext instead of lt_dlopen.
2355 * scmconfig.h.in: Do not change, as it is automatically generated.
2357 1999-07-25 Thomas Tanner <tanner@ffii.org>
2359 * dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c: deleted
2361 * Makefile.am: likewise, add INCLTDL (libltdl headers) to
2362 INCLUDES, set dlpreopened files in LDFLAGS, link libguile
2364 * dynl.c: use libltdl if DYNAMIC_LINKING is enabled,
2365 * guile.c: register preloaded modules
2366 * scmconfig.h.in: remove obsolete symbols
2368 2000-01-09 Gary Houston <ghouston@arglist.com>
2370 * These changes should make it unnecessary to call tzset from
2371 Scheme after modifying the TZ environment variable, even if the
2372 system date facilities cache the value.
2373 * stime.c (setzone, scm_localtime): added comments.
2374 (tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
2375 (setzone): don't call tzset.
2376 (restorezone): call tzset only if HAVE_TZSET is defined.
2377 (scm_tzset): don't define if HAVE_TZSET not defined. Change the
2378 doc string to indicate that this procedure isn't likely to do
2380 (scm_localtime, scm_strftime, scm_mktime): call tzset if
2381 LOCALTIME_CACHE is defined.
2383 2000-01-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2385 * posix.c (scm_sync): Return SCM_UNSPECIFIED.
2387 2000-01-09 Gary Houston <ghouston@arglist.com>
2389 * eval.c: define scm_unbound_variable_key ('unbound-variable).
2390 scm_lookupcar1: throw an error with key 'unbound-variable instead
2391 of 'misc-error when an unbound variable is encountered.
2393 * filesys.c (scm_mkdir, scm_rmdir, scm_getcwd, scm_select,
2394 scm_symlink, scm_readlink, scm_lstat),
2395 posix.c (scm_setpgid, scm_setsid, scm_ctermid, scm_tcgetpgrp,
2396 scm_tcsetpgrp, scm_uname, scm_setlocale, scm_mknod, scm_nice,
2398 simpos.c (scm_system),
2399 stime.c (scm_times, scm_strptime):
2400 move the HAVE_XXX feature tests out of the procedure bodies.
2401 don't use SCM_SYSMISSING.
2402 scm_validate.h (SCM_SYSMISSING): removed.
2403 error.h, error.c (scm_sysmissing): comment that this is deprecated.
2404 see ChangeLog entry for 1999-12-28.
2406 Sat Jan 8 19:52:04 2000 Greg J. Badros <gjb@cs.washington.edu>
2408 * scm_validate.h (SCM_VALIDATE_BOOL_COPY): Fix typo.
2410 Sat Jan 8 17:06:46 2000 Greg J. Badros <gjb@cs.washington.edu>
2412 * backtrace.c: Fix spelling typo in a comment.
2414 * snarf.h: Use new SCM_DOCS macro to encapsulate the non SCM_INIT
2415 text. Reformatted some of the expansions.
2417 Fri Jan 7 15:50:46 2000 Greg J. Badros <gjb@cs.washington.edu>
2419 * scm_validate.h (SCM_OUT_OF_RANGE): Use scm_out_of_range_pos to
2420 report the position of the argument.
2422 * error.h, error.c (scm_out_of_range_pos): Added this function to
2423 take extra "pos" argument, the position number of the errant
2426 * debug.c: Use SCM_OUT_OF_RANGE instead of scm_out_of_range.
2428 * snarf.h: Use SCM_HERE and SCM_INIT as names, not SCM_NOTSNARF
2429 and SCM_SNARFING. Also put the %%% in the SCM_INIT since Mikael
2430 prefers that and I'm reasonably indifferent.
2432 Fri Jan 7 15:03:32 2000 Greg J. Badros <gjb@cs.washington.edu>
2434 * snarf.h: Factor out differences between C++ and non-C++ into
2435 SCM_FUNC_CAST_ARBITRARY_ARGS macro. Modify all the snarf macro
2436 definitions to use SCM_NOTSNARF and SCM_SNARFING macros (like
2437 Mikael's macros, below, but changed names and SCM_SNARFING no
2438 longer expands to include %%% -- that must appear in the argument
2439 so that the token appears at the call-site as a reminder).
2441 2000-01-07 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2443 * snarf.h (SCM_INSITU, SCM_INIT): New snarf macros for use in user
2444 snarf macro definitions.
2446 2000-01-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2448 * chars.c (scm_integer_to_char): Use Greg's nice
2449 SCM_VALIDATE_INUM_RANGE macro for argument checking for closer
2452 Thu Jan 6 11:48:49 2000 Greg J. Badros <gjb@cs.washington.edu>
2454 * *.c, snarf.h: Replace GUILE_PROC1 with SCM_DEFINE1 throughout.
2456 Thu Jan 6 11:22:53 2000 Greg J. Badros <gjb@cs.washington.edu>
2458 * Makefile.am (ETAGS_ARGS): Switch to SCM_DEFINE, SCM_DEFINE1
2459 instead of GUILE_PROC.
2461 Thu Jan 6 11:21:49 2000 Greg J. Badros <gjb@cs.washington.edu>
2463 * alist.c: Do not report mismatch errors on some uses of `tmp' (do
2464 this by using SCM_ARG2 instead of `2' in the SCM_VALIDATE_CONS
2467 Thu Jan 6 09:54:33 2000 Dirk Herrmann <dirk@ida.ing.tu-bs.de> --gjb applied
2469 * scm_validate.h: Remove some redundant NIMP tests.
2471 * alist.c: minimize scope of the tmp variables, and initialize
2472 them when declared. The strange SCM_NIMP tests are replaced by
2473 SCM_CONSP tests that more closely reflect the intended semantics.
2474 However, we don't get a performance penalty here, because the
2475 SCM_CONSP test was performed by the ALISTCELL test anyway. * The
2476 extremely ugly use of ASRTGO macros was removed: The calls to
2477 ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a
2478 label parameter that only exists when SCM_RECKLESS is not defined.
2479 This works, because ASRTGO itself is defined in a way that it only
2480 makes use of the label parameter if SCM_RECKLESS is not defined
2481 (shudder!). Does guile make at all use of the possibility to
2482 define SCM_RECKLESS? * Codesize is likely to be reduced, since
2483 instead of two calls to SCM_ASSERT performed by the ALISTCELL test
2484 we now only get one test.
2486 * list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate. Also use
2487 SCM_NULLP instead of SCM_IMP. Drop use of "register" keyword on
2488 some variables in `list?'. Fix `reverse' and `reverse!'
2489 primitives to handle improper lists better.
2491 Wed Jan 5 11:24:53 2000 Greg J. Badros <gjb@cs.washington.edu>
2493 * *.[ch]: Whitespace changes -- added space after SCM_VALIDATE_*
2494 macros and SCM_DEFINE macros to match GNU coding standards.
2496 Wed Jan 5 11:04:24 2000 Greg J. Badros <gjb@cs.washington.edu>
2498 * *.[ch]: Replace GUILE_PROC w/ SCM_DEFINE.
2500 Wed Jan 5 10:59:06 2000 Greg J. Badros <gjb@cs.washington.edu>
2502 * *.[ch]: Replace SCM_VALIDATE_INT w/ SCM_VALIDATE_INUM for
2503 better consistency with the names of other SCM_VALIDATE_ macros
2504 and better conformance to guile naming policy.
2506 Wed Jan 5 10:50:39 2000 Greg J. Badros <gjb@cs.washington.edu>
2508 * ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a
2509 SCM_VALIDATE instead of 1 to avoid a check on the argument (since
2510 it's not the actual name of the formal).
2512 * guile-snarf.awk.in: Do argument/number mismatch checking and
2513 print warnings in an Emacs compile-mode parseable format.
2515 * struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/
2516 SCM_OUTOFRANGE as 3rd argument.
2518 * random.c: Fix argument/number mismatch (that I introduced :-( ).
2520 * __scm.h: Do not #define SCM_ARG* when snarfing;
2521 lets us distinguish between 1 and SCM_ARG1 when snarfing as only
2522 the former (using the number) requires the argument to match the
2523 formal in the current argument snarfing check.
2525 * snarf.h: Give new definition of SCM_ASSERT when in
2526 snarfing mode to output a lexically-identifiable sequence that the
2527 guile-snarf.awk script uses to verify argument/position matching.
2529 * ramap.c: Remove extraneous #undef FUNC_NAME.
2531 Wed Jan 5 08:36:38 2000 Greg J. Badros <gjb@cs.washington.edu>
2533 * guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the
2534 current version of the same functionality; it writes the .x output
2535 to stdout instead of directly into the file.
2537 Wed Jan 5 08:15:04 2000 Greg J. Badros <gjb@cs.washington.edu>
2539 * unif.c, symbols.c, strings.c, stacks.c, random.c, print.c,
2540 posix.c: Eliminated a bunch of SCM_NIMP(..)s that are now
2541 redundant with the safer macros. Patch from Dirk Hermann applied
2542 by hand. Thanks Dirk!
2544 * scm_validate.h: Added SCM_VALIDATE_VECTOR_OR_DVECTOR for some
2547 * ramap.c: whitespace change.
2549 Tue Jan 4 14:21:35 2000 Greg J. Badros <gjb@cs.washington.edu>
2551 * options.c, objects.c, keywords.c, gc.c: Some redundant SCM_NIMP
2552 removals from Dirk Hermann.
2554 * alist.c: Rename formals to match the parameter names in the
2555 documentation, updates to documentation. Thanks Dirk Hermann!
2557 2000-01-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2559 * eval.c (SCM_CEVAL): Reverse order of
2560 scm_stack_checking_enabled_p and SCM_STACK_OVERFLOW_P
2561 (Thanks to Brad Knotwell.)
2563 Mon Jan 3 08:30:02 2000 Greg Harvey <Greg.Harvey@thezone.net> (applied --01/03/00 gjb)
2565 * gc.c (scm_debug_newcell): Added SCM_SETCAR of the newly
2568 * pairs.h: Added a comment about the need for the SCM_SETCAR in
2571 Mon Jan 3 08:25:19 2000 Greg J. Badros <gjb@cs.washington.edu>
2573 * dynl-vms.c, debug.c, coop-threads.c, backtrace.c, eval.c: More
2574 SCM_NIMP tests that were redundant are now eliminated. Patches
2575 from Dirk Hermann applied by hand.
