 127
 128         The following patch was sent by Martin Grabmueller.  It makes sure
 129         that in case of parameter errors the correct function name is

 151         Grabmueller for providing this patch.
 152
 153 2001-01-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>

 167         (scm_make_sfptob):  Made static.  These return a type code now.
 168

 209         * strorder.c (string_less_p, string_ci_less_p):  New functions.
 210
 211         (scm_string_less_p, scm_string_ci_less_p):  Extracted the core
 212         functionality into string_less_p, string_ci_less_p respectively.

 325         from Matthias Köppe:
 326
 327         * objects.h (SCM_SET_ENTITY_SETTER): new macro.  SCM_ENTITY_SETTER

 333
 334         * gc.h (SCM_GC_SET_CARD_BVEC): new macro.  SCM_GC_CARD_BVEC casts

 348         changes.
 349         * ioext.c (scm_read_string_x_partial): don't crash if -1 is supplied
 350         for fdes.  if current input port is used, check that it's a file
 351         port.
 352
 353 2001-01-06  Gary Houston  <ghouston@arglist.com>
 354

 358         scm_read_string_x_partial.
 359         (scm_drain_input): use scm_take_from_input_buffers.
 360
 361 2001-01-06  Marius Vollmer  <mvo@zagadka.ping.de>
 362
 363         * validate.h (SCM_VALIDATE_NUMBER): New.
 364
 365 2001-01-03  Michael Livshin  <mlivshin@bigfoot.com>
 366
 367         * guardians.c (F_GREEDY, F_LISTED, F_DESTROYED, GREEDY_P,
 368         SET_GREEDY, LISTED_P, SET_LISTED, CLR_LISTED, DESTROYED_P,
 369         SET_DESTROYED): new defines/macros.
 370         (GUARDIAN_LIVE, GUARDIAN_ZOMBIES, GUARDIAN_NEXT): deleted.
 371         (add_to_live_list): takes a `guardian_t *' now, not SCM.
 372         (guardian_print): print more info.
 373         (guardian_apply): check if the guardian is destroyed, and throw an
 374         error if so.  take one more optional argument `throw_p'.
 375         (scm_guard): depending on the value of `throw_p', return a boolean
 376         result.
 377         (scm_get_one_zombie): remove redundant property test.
 378         (guardian_t): represent the various (currently 3, I hope nothing
 379         more gets added) boolean fields as bit flags.
 380         (scm_guardian_destroyed_p, scm_guardian_greedy_p): new predicates.
 381         (scm_destroy_guardian_x): new procedure.
 382
 383         * guardians.h: added prototypes for `scm_guardian_greedy_p' and
 384         `scm_guardian_destroyed_p'.  changed prototype for `scm_guard'.
 385
 386 2001-01-01  Gary Houston  <ghouston@arglist.com>
 387
 388         * fports.c (fport_write): bugfix: handle short writes for
 389         unbuffered ports too.  optimize the buffered case by minimizing
 390         the number of write/flush calls.
 391         (write_all): new helper procedure.
 392
 393 2000-12-30  Michael Livshin  <mlivshin@bigfoot.com>
 394
 395         * guardians.c (guardian_print): for sharing guardians, print that
 396         they are sharing.
 397         (scm_guard, scm_get_one_zombie): place the critical section
 398         barriers more correctly.

 404
 405         * guardians.c: (greedily_guarded_prop): deleted.
 406         (greedily_guarded_whash): new variable.  a doubly-weak hash table
 407         used to keep the "greedily guarded" object property.  the previous
 408         implementation (via primitive object properties) was incorrect due
 409         to its only-the-key-is-weak semantics.
 410         (scm_guard, get_one_zombie, scm_init_guardians): use/init
 411         `greedily_guarded_whash'.
 412
 413 2000-12-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 414
 415         * eval.c (check_map_args), gh_data.c (gh_set_substr,
 416         gh_scm2newstr, gh_get_substr, gh_symbol2newstr), print.c
 417         (scm_iprin1):  Use scm_remember_upto_here_1 instead of
 418         scm_remember.
 419
 420         * gc.[ch] (scm_remember_upto_here_1, scm_remember_upto_here_2,
 421         scm_remember_upto_here):  New functions.
 422
 423         (scm_remember):  Deprecated.
 424
 425 2000-12-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 426
 427         * continuations.c (scm_make_continuation):  Make variable cont
 428         volatile to let the compiler know that it won't be clobbered by
 429         longjmp.  (It wouldn't be anyway, but for some reason the compiler
 430         is not able to see that.)
 431
 432 2000-12-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 433
 434         This patch re-introduces the unused member "properties" of
 435         struct scm_subr_entry as requested by Mikael Djurfeldt.
 436
 437         * procs.h (scm_subr_entry):  Re-introduced member "properties".
 438
 439         (SCM_SUBR_PROPS):  Un-deprecated.
 440
 441         * procs.c (scm_make_subr_opt, scm_mark_subr_table):  Struct
 442         scm_subr_entry has a member "properties" again.
 443
 444 2000-12-28  Michael Livshin  <mlivshin@bigfoot.com>
 445
 446         * guardians.c (mark_dependencies_in_tconc): new function.
 447         (mark_dependencies): bug fix.  mark the dependencies of the known
 448         zombies, too.  duh.
 449
 450 2000-12-24  Michael Livshin  <mlivshin@bigfoot.com>
 451
 452         * gc.c: (scm_gc_mark_dependencies): use SCM_EQ_P for SCMs, not
 453         '=='.  also, return after calling `scm_gc_mark'.
 454
 455 2000-12-24  Michael Livshin  <mlivshin@bigfoot.com>
 456
 457         * gc.c: (scm_gc_mark_dependencies): new function.  like
 458         `scm_gc_mark', but doesn't mark the argument itself.  defined
 459         using an arrangement similar to that in eval.c: `scm_gc_mark' and
 460         `scm_gc_mark_dependencies' are derived from the same "template"
 461         by ugly preprocessor magic.
 462
 463         * gc.h: added prototype for `scm_gc_mark_dependencies'.
 464
 465         * init.c (scm_init_guile_1): call the renamed
 466         `scm_init_guardians'.
 467
 468         * guardians.h: changed prototypes for `scm_make_guardian' and
 469         `scm_init_guardians'.
 470
 471         * guardians.c (guardian_t): added new fields `greedy_p' and
 472         `listed_p'.
 473         (GUARDIAN_P): predicate that says whether its argument is a
 474         guardian.
 475         (GUARDIAN_GREEDY_P, GUARDIAN_LISTED_P): new predicates.
 476         (greedy_guardians, sharing_guardians): new variables.  hold the
 477         greedy and sharing live guardian lists, respectively.
 478         (first_live_guardian, current_link_field): removed.
 479         (greedily_guarded_prop): new variable.  holds the "is greedily
 480         guarded" object property.
 481         (self_centered_zombies): new variable.  stores guarded objects
 482         that are parts of cycles.
 483         (add_to_live_list): new function, introduced to decouple marking a
 484         guardian and adding it to the live list.
 485         (guardian_mark): call `add_to_live_list'.
 486         (guardian_print): print whether the guardian is greedy or not.
 487         also change "live" and "zombie" to "reachable" and "unreachable"
 488         respectively, to be less confusing.
 489         (scm_guard): if the guardian is greedy, test whether the object is
 490         already greedily marked.  throw an error if so.
 491         (scm_get_one_zombie): if the guardian is greedy, remove the
 492         "greedily guarded" property from the object.
 493         (scm_make_guardian): add a new optional boolean argument which
 494         says whether the guardian is greedy or sharing.
 495         (guardian_gc_init): init the new live lists.
 496         (mark_dependencies): new function.
 497         (mark_and_zombify): new function.
 498         (guardian_zombify): reworked to support the new guardian
 499         semantics.  move some logic to `mark_dependencies' and
 500         `mark_and_zombify'.
 501         (whine_about_self_centered_zombies): new function.  installed in
 502         the `after-gc-hook' to complain about guarded objects which are
 503         parts of cycles.
 504         (scm_init_guardians): init the new stuff.  renamed from
 505         `scm_init_guardian'.
 506
 507 2000-12-23  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 508
 509         * procs.h (scm_subr_entry):  Removed unused struct member
 510         "properties".
 511
 512         (SCM_SUBR_PROPS):  Deprecated.
 513
 514         * procs.c (scm_make_subr_opt, scm_mark_subr_table):  Struct
 515         scm_subr_entry does not have a member "properties" any more.
 516
 517 2000-12-22  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 518
 519         * procs.h (scm_subr_entry):  Removed unused struct member
 520         "documentation".
 521
 522         (SCM_SUBR_DOC):  Deprecated.
 523
 524         * procs.c (scm_make_subr_opt):  Eliminate use of scm_intern0 in
 525         favor of scm_str2symbol.  Similarly, prefer scm_sysintern over
 526         scm_sysintern0.
 527
 528         (scm_make_subr_opt, scm_mark_subr_table):  Struct scm_subr_entry
 529         does not have a member "documentation" any more.
 530
 531 2000-12-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 532
 533         * eval.c (restore_environment):  Make sure that changes to the
 534         current environment will take effect when re-entering the dynamic
 535         scope.
 536
 537 2000-12-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 538
 539         * goops.h (SCM_PUREGENERICP):  Include the SCM_STRUCTP test.
 540
 541         * goops.c (scm_sys_invalidate_method_cache_x, scm_m_atdispatch,
 542         scm_pure_generic_p):  The SCM_STRUCTP test is implied.
 543
 544 2000-12-20  Gary Houston  <ghouston@arglist.com>
 545
 546         * continuations.c (continuation_apply): subtract the length of
 547         continuation->dynenv, not the dynenv itself.  I broke it last
 548         time I changed this file.  thanks to Bernard Urban.
 549
 550 2000-12-16  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 551
 552         * goops.c (remove_duplicate_slots, maplist,
 553         scm_sys_initialize_object, scm_sys_prep_layout_x,
 554         scm_sys_inherit_magic_x, scm_instance_p,

 562         * goops.h: #include "libguile/validate.h"
 563         (SCM_CLASSP, SCM_GENERICP, SCM_METHODP): Moved from goops.c with
 564         prefix "SCM_".
 565         (SCM_VALIDATE_INSTANCE, SCM_VALIDATE_ACCESSOR, SCM_VALIDATE_CLASS,
 566         SCM_VALIDATE_GENERIC, SCM_VALIDATE_METHOD): New macros.
 567         * goops.c (CLASSP, GENERICP, METHODP): Moved to goops.h with

 590         (scm_assert_bound, scm_at_assert_bound_ref, scm_sys_goops_loaded):
 591         Declared as static functions.
 592         (s_class_of, scm_class_of): Replaced SCM_PROC by SCM_DEFINE
 593         in object.c.
 594         * object.c (scm_class_of): Use SCM_DEFINE.
 595
 596 2000-12-16  Keisuke Nishida  <kxn30@po.cwru.edu>
 597
 598         * symbols.h (scm_symbols_prehistory): Added prototype.
 599
 600 2000-12-16  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 601
 602         * environments.[ch] (scm_system_environment):  New variable, will
 603         replace scm_symhash soon.  We may decide for a better name and
 604         also to split this up into a set of environments later.
 605
 606         (scm_environments_prehistory):  Initialize scm_system_environment.
 607
 608         * init.c (scm_init_guile_1):  scm_environments_prehistory requires
 609         storage to be initialized.
 610
 611 2000-12-15  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 612
 613         * eval.c (change_environment, inner_eval, restore_environment):
 614         New functions.
 615
 616         (scm_eval):  Bring the global variable that holds the current
 617         environment up to date when entering or leaving the scope of the
 618         evaluated code.  Thanks to Matthias Koeppe for the bug report.
 619
 620 2000-12-13  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 621
 622         * numbers.c (scm_init_numbers):  Re-introduced bindings for
 623         most-positive-fixnum and most-negative-fixnum as requested by
 624         Mikael Djurfeldt.
 625
 626 2000-12-12  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 627
 628         The variable scm_symbols is made static within symbols.c and
 629         renamed to symbols.  The initialization of the symbols hash table
 630         is done in function scm_symbols_prehistory.
 631
 632         * gc.c (scm_init_storage):  Don't initialize scm_symbols.  Don't
 633         define most-positive-fixnum, most-negative-fixnum and
 634         bignum-radix.
 635
 636         * init.c (scm_init_guile_1):  Call scm_symbols_prehistory.
 637
 638         * root.h (scm_symbols):  Not in scm_sys_protects any more.
 639
 640         * symbols.c (symbols):  Renamed from scm_symbols and made static.
 641
 642         (scm_mem2symbol):  scm_symbols is renamed to symbols.
 643
 644         * symbols.[ch] (scm_symbols_prehistory):  Added.
 645
 646 2000-12-12  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 647
 648         * gc.c (scm_init_storage), root.h (scm_weak_symhash, scm_symbols):
 649         Removed the former scm_weak_symhash hash table.  Added scm_symbols
 650         hash table.
 651
 652         * stacks.c (get_applybody):  scm_sym2vcell may return #f.
 653
 654         * symbols.c (scm_mem2symbol):  This function is now responsible
 655         for creating symbol objects and storing them in the global
 656         scm_symbols hash table.
 657
 658         (scm_str2symbol):  Rewritten in terms of scm_mem2symbol.
 659
 660         (scm_sym2vcell):  For system bindings, there is now only one
 661         obarray - scm_symhash.  If scm_sym2vcell is called to look up a
 662         symbol that can't be found and shall not be created, #f is
 663         returned.  Most callers of scm_sym2vcell have expected this
 664         behaviour anyway.
 665
 666         (scm_intern_obarray_soft):  Removed reference to scm_weak_symhash
 667         from comment.
 668
 669         (scm_intern_obarray_soft, scm_sysintern0_no_module_lookup):  These
 670         functions are not responsible for symbol creation any more, only
 671         for creation of bindings.
 672
 673         (scm_symbol_value0):  Don't use scm_intern_obarray_soft to create
 674         a symbol object.
 675
 676         (scm_symbol_interned_p):  scm_weak_symhash is removed.
 677
 678         * symbols.[ch] (scm_builtin_weak_bindings):  Removed.  There are
 679         no weak bindings any more.
 680
 681 2000-12-12  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 682
 683         * hooks.c (scm_create_hook), script.c
 684         (scm_compile_shell_switches), snarf.h (SCM_VCELL,
 685         SCM_GLOBAL_VCELL, SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT):  Create
 686         a binding in one go (instead of first creating a vcell and then
 687         setting its cdr).
 688
 689 2000-12-12  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 690
 691         * hash.[ch] (scm_string_hash), symbols.[ch] (scm_string_hash):

 990         * gc.c (scm_init_gc):  Don't create a binding for %gc-thunk.

 995
 996         (scm_gsubr_apply):  Use SCM_GSUBR_MAX instead of hard-coded value.

1010         (SCM_CEVAL, SCM_APPLY):  Remove #ifdef CCLO conditionals.  Without

1031         immediates.  Got rid of one goto command.
1032
1033 2000-12-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>

1041

1050
1051         (guardian_apply, scm_guard, scm_get_one_zombie,
1052         scm_make_guardian):  Don't use a compiled closure.
1053
1054         (guardian_zombify):  Prefer !SCM_NULLP over SCM_NIMP.  No need to
1055         use SCM_GCCDR any more.  Simplified loop condition.
1056
1057         (scm_init_guardian):  Don't use scm_make_smob_type_mfpe for smob
1058         initialization.  Initialize applicable smob.
1059

1072         scm_tc16_complex):  Eliminate hard-coded value of scm_tc7_smob.
1073
1074 2000-12-01  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1075
1076         * list.[ch] (scm_c_memq):  Added as a fast C level alternative for
1077         scm_memq for the case that the list parameter is known to be a
1078         proper list.
1079
1080         * goops.c (filter_cpl, remove_duplicate_slots, applicablep),
1081         goops.h (SCM_SUBCLASSP):  Use scm_c_memq if we are sure that we
1082         pass proper lists.

1087         scm_get_keyword, scm_slot_ref_using_class,
1088         scm_slot_set_using_class_x):  Update the code to match guile's
1089         current style (e. g. using SCM_DEFINE, adding comments, removing
1090         unnecessary SCM_NIMP tests etc.).
1091
1092 2000-11-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1093
1094         Thanks to Julian Satchell for the bug report:
1095
1096         * coop-threads.c (scm_join_thread):  Check whether a thread is
1097         finished before trying to join it.
1098
1099         * coop.c (coop_aborthelp, coop_join):  When a thread finishes, its

1101
1102 2000-11-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1103
1104         * strop.c (scm_i_index):  Removed outdated comment.

1114
1115 2000-11-26  Gary Houston  <ghouston@arglist.com>
1116
1117         * reimplementation of values, call-with-values as primitives:
1118
1119         * values.c, values.h: new files.  use a struct to contain multiple
1120         values, similar to the previous Scheme-level implementation.
1121         * Makefile.am: add values.c, values.h, values.x.
1122         * continuations.c (continuation_apply): support R5RS multiple value
1123         continuations.
1124         * init.c: call scm_init_values.
1125         * struct.h: define SCM_SET_STRUCT_PRINTER.
1126
1127 2000-11-25  Gary Houston  <ghouston@arglist.com>
1128
1129         * use an applicable SMOB to represent continuations, instead of a
1130         custom tc7 type.  This will make it easier to support R5RS
1131         multiple value continuations, without the use of a Scheme-level
1132         wrapper.
1133
1134         * continuations.c (scm_tc16_continuation, continuation_mark,
1135         continuation_free, continuation_print, continuation_apply):
1136         new SMOB support.
1137         (scm_make_continuation): new procedure, replaces scm_make_cont

1141         (scm_call_continuation): removed.
1142         * continuations.h (struct scm_contregs): add num_stack_items and
1143         stack fields.  previously stack was stored following this struct:
1144         use a tail array instead.
1145         (SCM_CONTINUATIONP): new macro.
1146         (SCM_CONTINUATION_LENGTH, SCM_SET_CONTINUATION_LENGTH):
1147         rewritten.
1148         (SCM_SET_CONTREGS): removed.

1150         * debug.c, gc.c, hash.c, print.c, procprop.c, procs.c:
1151         removed scm_tc7_contin support.
1152         * eval.c: use scm_make_continuation instead of scm_make_cont.
1153         don't set jump buffers here.  remove scm_tc7_contin support.
1154         * init.c, root.c: create SMOB continuation for rootcont instead
1155         of scm_tc7_contin.  call scm_init_continuations before
1156         scm_init_root.
1157         * root.c: remove support for static jmpbuf.  It's not used by
1158         default and I broke it.  create SMOB continuation for rootcont.
1159         * stacks.c: use SCM_CONTINUATIONP.

1161 2000-11-24  Matthias Koeppe  <mkoeppe@mail.math.uni-magdeburg.de>
1162
1163         * goops.c (filter_cpl, remove_duplicate_slots), goops.h
1164         (SCM_SUBCLASSP):  Fix previous change:  In contrast to
1165         scm_sloppy_memq the function scm_memq returns #f if the
1166         object was not contained in the list.
1167
1168 2000-11-24  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1169

1177
1178         (scm_sloppy_num2ulong, scm_sys_logand):  Removed.  Guile's logand
1179         function now provides the desired behaviour.
1180
1181         * goops.c (filter_cpl, remove_duplicate_slots), goops.h
1182         (SCM_SUBCLASSP):  Don't use deprecated scm_sloppy_memq.

1303
1304         * Makefile.am: Install guile-procedures.txt in version-specific
1305         directory to enable multiple installed guile versions.  Suggested
1306         by Karl M. Hegbloom <karlheg@debian.org, patch by Matthias Koeppe.

1308 2000-11-13  Gary Houston  <ghouston@arglist.com>
1309
1310         * fports.c: include gc.h.
1311         (fport_flush, fport_close): silently ignore I/O errors when
1312         closing a port during gc.  it's better than aborting in scm_error.
1313
1314         * throw.c (scm_handle_by_message): remove obsolete comment.
1315
1316 2000-11-12  Gary Houston  <ghouston@arglist.com>
1317
1318         * fports.c (scm_open_file): fix the 'b' option.  Thanks
1319         to George Caswell.
1320
1321 2000-11-09  Gary Houston  <ghouston@arglist.com>
1322
1323         * ports.c, ports.h (scm_close_all_ports_except): deprecated.
1324         use port-for-each.  Updated its docstring.
1325
1326 2000-11-07  Gary Houston  <ghouston@arglist.com>
1327
1328         * ports.c (scm_port_for_each): new proc.  implements port-for-each,
1329         which applies a procedure to each port in the port table.
1330         ports.h: declare scm_port_for_each.
1331
1332         * ioext.c (scm_dup2): new proc.  implements "dup2" which is a simple
1333         wrapper for the dup2 system call (unlike dup->fdes or
1334         primitive-move->fdes).
1335         * ioext.h: declare scm_dup2.
1336
1337         * filesys.c (scm_close_fdes): new proc.  implements "close-fdes"
1338         which is a simple wrapper for close system call (unlike scm_close).
1339         * filesys.h: declare for scm_close_fdes.
1340
1341 2000-11-06  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>
1342
1343         * eval.c (SCM_IM_DISPATCH), objects.c (scm_mcache_lookup_cmethod):
1344         Count n_specialized + 1 turns before letting a match through.
1345
1346         * goops.c (scm_sys_invalidate_method_cache_x): Don't convert
1347         scm_si_n_specialized from fixnum and don't take absolute value.
1348         (Thanks to Lars J. Aas.)
1349
1350 2000-11-04  Gary Houston  <ghouston@arglist.com>
1351
1352         * ports.c (scm_port_p): new function, implements "port?" which
1353         is mentioned in R5RS.
1354         * ports.h: declare scm_port_p.
1355
1356 2000-11-01  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1357
1358         * backtrace.c (display_expression, display_error_body), fports.c
1359         (prinfport), print.c (scm_iprin1):  Test for symbols and strings
1360         explicitly instead of using SCM_ROSTRINGP.
1361
1362         * backtrace.c (scm_display_error_message):  Don't pass a symbol to
1363         scm_simple_format.  Prefer high-level output functions.
1364
1365         (display_error_body):  When displaying procedure names, give
1366         preference to the name passed as a parameter.  Only if none is
1367         given extract a name from the stack information.
1368
1369         * fports.c (scm_fdes_to_port, prinfport), gc.c (scm_gc_mark),
1370         ports.c (scm_port_filename, scm_set_port_filename_x):  Use
1371         SCM_(SET_)?FILENAME.
1372
1373         * gh_data.c (gh_set_substr, gh_scm2newstr, gh_get_substr,
1374         gh_symbol2newstr):  Use scm_remember instead of a pair of calls to
1375         scm_protect/unprotect_object.
1376
1377         * goops.c (make_struct_class), objects.c (scm_class_of):  Struct
1378         table names are symbols.
1379
1380         * ports.h (SCM_SET_FILENAME):  Added.
1381
1382         * print.c (scm_iprin1):  Don't use scm_puts to write symbols or
1383         strings in order to treat substrings right.  Reposition call to
1384         scm_remember after the last use of object's data.
1385
1386         (scm_simple_format):  Treat messages that are substrings right.
1387
1388         * symbols.h (SCM_ROSTRINGP):  Deprecated.
1389
1390 2000-11-01  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1391
1392         * environments.c (obarray_replace, obarray_retrieve,
1393         obarray_remove):  Don't use '==' to compare SCM objects.
1394
1395         * posix.c (scm_getgroups):  Don't create a redundant string.
1396
1397 2000-11-01  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1398
1399         * symbols.c (scm_sym2vcell, scm_sym2ovcell_soft,
1400         scm_intern_symbol, scm_unintern_symbol):  Symbol objects already
1401         hold their hash values, no need to recompute them.
1402
1403         (scm_intern_obarray_soft):  Speed up search for a matching symbol
1404         by comparing the hash values first.
1405
1406 2000-10-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1407
1408         * unif.c (scm_make_uve, scm_dimensions_to_uniform_array):  Don't
1409         allow vectors longer than SCM_LENGTH_MAX. This removes the
1410         SCM_HUGE_LENGTH trick, i. e. storing a vector length greater than
1411         SCM_LENGTH_MAX at the beginning of the vector's memory.  Since not
1412         all of guile's code was implemented to be aware of this trick, it
1413         is unlikely that it was used anyway.  We can implement such a
1414         feature more cleanly by using double cells for uniform vector
1415         types.
1416
1417         (scm_shap2ra):  Replace SCM_IMP and SCM_NIMP tests by more
1418         straightforward predicates.
1419
1420         (scm_dimensions_to_uniform_array):  Require that for dimensions
1421         given as lower-bound/upper-bound pairs the upper-bound is never
1422         less than the lower bound.
1423
1424 2000-10-27  Dirk Herrmann  <D.Herrmann@tu-bs.de>

1461         make sure the characters of a string are followed by a \0.
1462         Further, use SCM_STRING_CHARS instead of SCM_ROCHARS on the

1472         details from the scheme comment.
1473
1474         * error (scm_error_scm):  Don't accept a symbol as message
1475         parameter.  Fix substring handling.

1477         * posix.c (environ_list_to_c):  Use memcpy to copy environment

1492
1493         * strings.h (SCM_STRING_COERCE_0TERMINATION_X):  Added.  This is
1494         intended to replace the macro SCM_COERCE_SUBSTR.  Such a macro
1495         will be necessary, even after copy-on-write strings will be added
1496         to guile, but the current naming is inappropriate.
1497

1499         scm_string_less_p, scm_string_ci_less_p):  Don't accept symbols as
1500         input parameters.  Further, the functions that test for equality
1501         are rewritten to compare from back to front, the others are also a
1502         little bit more polished.

1504 2000-10-25  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>
1505
1506         This change merges the GOOPS code into Guile.  However, GOOPS
1507         is still not initialized until someone asks for the module.
1508         We need to optimize GOOPS initialization time before initializing
1509         it together with the rest of libguile.  We also need to add the
1510         C API + primitive methods.  Then we can start using it to
1511         modularize Guile, implement a real exception system etc.
1512
1513         * goops.c, objects.c, objects.h, eval.c (scm_make_extended_class,
1514         scm_make_port_classes, scm_change_object_class,
1515         scm_memoize_method): Changed to ordinary functions (was plugin
1516         slots).
1517
1518         * goops.c (wrap_init, scm_wrap_object): Unconditionally use
1519         SCM_STRUCT_GC_CHAIN.
1520         (scm_goops_version): Removed.
1521         (scm_oldfmt): and all uses of it: Removed.
1522         (scm_shared_array_root, scm_shared_array_offset,
1523         scm_shared_array_increments): Removed.
1524         (scm_init_goops): No need to support two arg mutex init.
1525         Removed #include "versiondat.h", #include "goops.h".
1526
1527         * goops.h: Removed various superfluous conditions.
1528         Renamed class --> cls, new --> newinst in order to accomodate
1529         C++.
1530
1531         * init.c (scm_init_guile_1): Call the goops module registration
1532         function.
1533         Added #include "libguile/goops.h".
1534
1535         * Makefile.am (libguile_la_SOURCES): Added goops.c
1536         (DOT_X_FILES): Added goops.x
1537         (DOT_DOC_FILES): Added goops.doc

1543
1544         (scm_gc_sweep):  SCM_CONTREGS is never NULL.
1545
1546         * gc.c (scm_gc_sweep), vectors.c (scm_make_vector):  Don't
1547         allocate/free memory for zero length vectors.
1548
1549         * vectors.[ch] (scm_vector_set_length_x):  Deprecated.

1554         this function when the API gets reviewed.
1555
1556         * async.c (SET_ASYNC_GOT_IT):  Use SCM_TYP16 instead of doing bit

1566         SCM_ROLENGTH if the object is known to be a string or substring.
1567
1568         * eval.c (scm_lookupcar):  Use SCM_ITAG7 instead of doing bit
1569         operations directly.
1570
1571         * filesys.c (scm_dirname, scm_basename):  Don't create shared
1572         substrings as these are going to disappear from guile.
1573
1574         * gc.c (scm_gc_sweep):  Use SCM_UVECTOR_LENGTH instead of
1575         SCM_HUGE_LENGTH.  (The SCM_HUGE_LENGTH mechanism does not work
1576         correctly anyway.)
1577
1578         * gc.h (SCM_FREEP, SCM_NFREEP):  Deprecated.
1579
1580         * read.c (scm_flush_ws):  Don't compare SCM values directly.

1583         system_transformer and top_level_lookup_closure_var from struct.
1584         (Since eval is now R5RS, binary compatibility is not granted
1585         anyway.)
1586
1587         * simpos.c (scm_system):  Fix condition.
1588
1589         * strings.c (scm_string_length, scm_string_ref, scm_substring,

1592         (scm_gensym, scm_gentemp):  Replace SCM_VALIDATE_STRINGORSUBSTR
1593         with SCM_VALIDATE_STRING, since they do the same thing.

1932         SCM_CHARS.
1933
1934 2000-09-22  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1935
1936         * gc.c (scm_gc_mark, scm_gc_sweep), tags.h:  Removed the
1937         scm_tc7_lvector type tag.
1938
1939 2000-09-22  Dirk Herrmann  <D.Herrmann@tu-bs.de>

1942         code.
1943
1944         * gc.c (scm_gc_sweep):  Use SCM_STRING_CHARS or SCM_SYMBOL_CHARS
1945         instead of SCM_CHARS.
1946
1947 2000-09-22  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1948
1949         * backtrace.c (display_frame_expr), environments.c

1962
1963 2000-09-22  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1964
1965         * strings.h (SCM_STRING_CHARS):  Added, should be used instead of

1969
1970         * symbols.h (SCM_SYMBOL_CHARS):  Added, should be used instead of

1982
1983         * numbers.c (scm_istr2flo): Throw an `out of range' error when
1984         exponent is too large instead of returning `#f'.  The rationale is
1985         that in this case the string represents a valid number but we
1986         can't deal with it.
1987
1988 2000-09-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1989
1990         * symbols.c (scm_intern_obarray_soft,
1991         scm_sysintern0_no_module_lookup):  Make sure that symbol

1996
1997         * throw.c (scm_handle_by_message):  Added a FIXME comment.
1998
1999         (scm_ithrow):  Removed some redundant tests.  When compiling on

2001
2002 2000-09-14  Gary Houston  <ghouston@arglist.com>
2003
2004         * print.c (scm_iprin1): write the ascii delete character as #\del
2005         instead of '#\', so it can be read back.  like in SCM.
2006
2007 2000-09-12  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>
2008
2009         * symbols.c (duplicate_string): Don't try to copy the byte after
2010         the string.  This might not be `\0' and might even not be
2011         allocated memory.
2012
2013 2000-09-12  Dirk Herrmann  <D.Herrmann@tu-bs.de>
2014

2017 2000-09-12  Dirk Herrmann  <D.Herrmann@tu-bs.de>
2018
2019         This patch unifies the formerly distinct ssymbol and msymbol types
2020         to a common symbol type scm_tc7_symbol.  The representation of the
2021         new symbol type uses a double cell with the following layout:
2022         <type/length, chars, raw_hash, prop-pair>, where the car of
2023         prop-pair holds the symbol's function property and the cdr of
2024         prop-pair holds the symbol's other properties.  In the long run,
2025         these properties will be removed.  Then, the generic property
2026         functions will be uses.
2027
2028         * eval.c (SCM_CEVAL), objects.c (scm_class_of), print.c
2029         (scm_iprin1), tag.c (scm_tag):  Use scm_tc7_symbol instead of
2030         scm_tc7_ssymbol, scm_tc7_msymbol or scm_tcs_symbols.
2031
2032         * gc.c (scm_gc_mark):  Mark the symbols property pair.
2033
2034         (scm_gc_sweep):  There are no symbol slots any more.
2035
2036         * hash.c (scm_hasher):  Instead of re-calculating the hash value
2037         of a symbol, use the raw_hash value stored in the symbol itself.
2038
2039         * properties.h:  Fix typo.
2040
2041         * strings.[ch] (scm_makstr, scm_makfromstr):  The slot parameter
2042         is not used any more.
2043
2044         * symbols.[ch] (scm_strhash):  Deprecated, replaced by a macro.
2045
2046         (scm_intern_obarray_soft):  Made softness parameter unsigned.
2047
2048         (scm_string_hash):  New function with the same functionality as
2049         scm_strhash had before, except that the hash value is not adjusted
2050         to a hash table size.  Instead, the 'raw' hash value is returned.
2051
2052         * symbols.c (duplicate_string):  New static convenience function.
2053
2054         (scm_sym2vcell, scm_sym2ovcell_soft, scm_intern_obarray_soft):
2055         Renamed local variable from scm_hash to hash.
2056
2057         (scm_intern_obarray_soft):  Don't check for a negative softness
2058         any more.  When generating symbol cells, use the new layout and
2059         store the raw hash value in the symbol's cell.
2060
2061         (scm_symbol_to_string):  Removed unnecessary cast.
2062
2063         (scm_intern_symbol, scm_unintern_symbol):  Use scm_string_hash to
2064         determine the hash values.
2065
2066         (msymbolize):  Removed.
2067
2068         (scm_symbol_fref, scm_symbol_pref, scm_symbol_fset_x,
2069         scm_symbol_pset_x, scm_symbol_hash):  No need to distinguish
2070         between different symbol types any more.
2071
2072         (scm_symbol_hash):  Comment fixed.
2073
2074         * symbols.h:  Comment about the distinction between ssymbols and
2075         msymbols removed.
2076
2077         (SCM_SYMBOLP, SCM_ROSTRINGP):  No need to distinguish between
2078         different symbol types any more.
2079
2080         (SCM_PROP_SLOTS, SCM_SET_PROP_SLOTS):  Added.
2081
2082         (SCM_SYMBOL_FUNC, SCM_SET_SYMBOL_FUNC, SCM_SYMBOL_PROPS,
2083         SCM_SET_SYMBOL_PROPS, SCM_SYMBOL_HASH, SCM_SET_SYMBOL_HASH):  Use
2084         the new symbol cell layout.
2085
2086         * tags.h (scm_tc7_ssymbol, scm_tc7_msymbol, scm_tcs_symbols):
2087         Deprecated.
2088
2089 2000-09-12  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>
2090
2091         * symbols.h (scm_gentemp): Declared.
2092
2093         * symbols.c (scm_gensym): Reimplemented.  Now only takes one
2094         optional argument which should be a *string*.
2095         (scm_gentemp): Reimplemented and moved from boot-9.scm.
2096
2097 2000-09-10  Keisuke Nishida  <kxn30@po.cwru.edu>
2098
2099         * modules.c: Use applicable smobs for eval closures instead of
2100         compiled closures.  Include "libguile/smob.h".
2101         (f_eval_closure): Removed.
2102         (scm_eval_closure_tag): New variable.
2103         (scm_eval_closure_lookup): Renamed from eval_closure.
2104         This function now takes a smob instead of a compiled closure.
2105         (scm_standard_eval_closure): Create a smob instead of a compiled
2106         closure.
2107         (scm_init_modules): Initialize the eval closure type as a smob.
2108         * modules.h (SCM_EVAL_CLOSURE_P): New macro.
2109         (scm_eval_closure_tag, scm_eval_closure_lookup): Declare.
2110         * symbols.c: Include "libguile/smob.h".
2111         (scm_sym2vcell): Call scm_eval_closure_lookup directly if THUNK
2112         is an eval closure.
2113
2114 2000-09-10  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>
2115
2116         * Makefile.am (.x.doc): Bugfix: Added $(srcdir) to path in order
2117         to allow for builds in separate tree.
2118
2119         * symbols.c (scm_gensym): Bugfixed my previous bugfix.  (Thanks to
2120         Dale P. Smith.)
2121
2122 2000-09-10  Keisuke Nishida  <kxn30@po.cwru.edu>
2123
2124         * eval.c (SCM_APPLY): Fixed bugs in the applicable-smob calls.
2125

2132         (obarray_enter, obarray_remove):  Documentation improved.
2133
2134         (obarray_replace):  Added.
2135
2136         (leaf_environment_define, leaf_environment_undefine):  Cleaned up
2137         and optimized.
2138
2139 2000-09-05  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>
2140
2141         * symbols.c (scm_gensym): Check that argument is a symbol, not a
2142         string.  (Thanks to Ralf Mattes.)
2143
2144 2000-09-05  Marius Vollmer  <mvo@zagadka.ping.de>
2145
2146         * init.c: Include "libguile/properties.h".
2147
2148         * gh_data.c (gh_scm2char): Validate that argument is a character.
2149
2150 2000-08-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>
2151
2152         * environments.h (SCM_IMPORT_ENVIRONMENT_P,
2153         SCM_EXPORT_ENVIRONMENT_P):  Before fetching the environment
2154         functions, make sure that we really got an environment.
2155
2156 2000-09-03  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>
2157
2158         * validate.h (SCM_VALIDATE_NUMBER_DEF_COPY): New macro.
2159
2160 2000-09-03  Marius Vollmer  <mvo@zagadka.ping.de>
2161
2162         * Makefile.am (.x.doc): Pretend to create .doc files from .x files
2163         and give explicit dependencies for .x files that depend on
2164         generated files.  This allows parallel builds.  Thanks to Matthias
2165         Koeppe!
2166
2167 2000-08-27  Marius Vollmer  <mvo@zagadka.ping.de>
2168
2169         * Makefile.am: Added gc_os_dep.c, properties.c, properties.x,
2170         properties.h and properties.doc in the suitable places.
2171
2172         * init.h (scm_init_guile): New prototype.
2173
2174         * init.c (scm_init_guile, scm_init_guile_1): New interface for
2175         initializing Guile that does return to the caller.
2176         (scm_boot_guile_1): Use scm_init_guile_1 to initialize Guile.
2177         Do not establish a catch-all, this is no longer needed.
2178
2179         * root.h (scm_properties_whash): New `sys_protect', used in
2180         properties.c.
2181
2182         * throw.c (scm_ithrow): Perform catch-all handling here when no
2183         suitable handler has been found.  That way, we don't have to rely
2184         on the user establishing a catch-all, which might be difficult for
2185         him if he is using scm_init_guile instead of scm_boot_guile.
2186
2187 2000-09-03  Neil Jerram  <neil@ossau.uklinux.net>
2188
2189         * vectors.c (scm_vector): Docstring: add @deffnx line for
2190         list->vector.
2191

2198         incomplete Texinfo reference to a node in r4rs.texi.
2199         (scm_symbol_to_string): Escape double quotes correctly within
2200         docstring.
2201
2202         * struct.c (scm_make_struct, scm_make_vtable_vtable): Docstring
2203         fixes: `@dots' changed to `@dots{}'.

2205         * strop.c (scm_substring_move_x): Docstring: add @deffnx lines for
2206         substring-move-left! and substring-move-right!.
2207
2208         * strings.c (scm_string): Docstring: add @deffnx line for

2215         inserted.
2216

2220         array-map-in-order!.
2221
2222         * posix.c (scm_mknod): Docstring format fix: missing newlines
2223         inserted.
2224
2225         * modules.c (scm_interaction_environment):  Docstring fix: add
2226         newlines.
2227
2228         * eval.c (scm_cons_source): Added newly written docstring.
2229
2230 2000-09-03  Michael Livshin  <mlivshin@bigfoot.com>
2231
2232         the following changes let Guile get rid of the `allocated' cell
2233         state.
2234
2235         * smob.c (scm_smob_prehistory): don't init the "allocated" smob
2236         type.
2237
2238         * tags.h (scm_tc16_allocated): removed.
2239
2240         * gc.h: removed now-obsolete comments about the `allocated' cell
2241         state.
2242         (SCM_NEWCELL): don't change cell type to `allocated'.
2243         (SCM_NEWCELL2): ditto.
2244
2245         * gc.c (scm_mark_locations): mark freecells too, and don't worry
2246         about any possible false positives.
2247         (scm_debug_newcell): don't change cell type to `allocated'.
2248         (scm_debug_newcell2): ditto.
2249         (scm_gc_for_newcell): ditto.
2250         (scm_gc_mark): remove the tc16_allocated case.
2251
2252 2000-08-26  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>
2253
2254         * gdbint.c (gdb_print): Removed superfluous macro definition.
2255
2256         * objects.c (scm_init_objects), print.c (scm_init_print), struct.c
2257         (scm_init_struct): First arg to scm_make_vtable_vtable should be a
2258         string, not a symbol.  (`make-vtable-vtable' needs to append this
2259         string to another string and then pass it through
2260         `make-struct-layout'.)
2261
2262         * stacks.c (scm_init_stacks): Pass a string, not a layout object,
2263         to scm_make_vtable_vtable.  (Thanks to Dale P. Smith.)
2264
2265         * struct.c (scm_make_struct_layout): Removed reference to
2266         "read-only string" in comment; Check that argument is a string.
2267         (scm_make_vtable_vtable): Check that argument is a string.
2268
2269         * environments.c (scm_init_environments): All internal includes in
2270         libguile must use the prefix "libguile/" in path names since inly
2271         the top-level source directory is on the include list.  (That, in
2272         turn, is because we want to distinguish between system header
2273         files and hedares files internal to libguile.)
2274
2275         * strings.c (scm_make_shared_substring, scm_read_only_string_p):
2276         Deprecated.
2277         (scm_string_length, scm_string_ref, scm_substring,
2278         scm_string_append): Don't accept symbols as arguments (R5RS).
2279
2280 2000-08-25  Neil Jerram  <neil@ossau.uklinux.net>
2281
2282         * ports.c (scm_set_port_column_x): Fix docstring so that it
2283         mentions set-port-line! rather than set-port-column! twice.
2284
2285         * guardians.c (scm_make_guardian): Remove spurious . from doc string.
2286
2287 2000-08-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>
2288
2289         * Makefile.am:  Added all necessary environments.* files.
2290
2291         * init.c:  Include environments.h.
2292
2293         (scm_boot_guile_1):  Initialize the environments.
2294
2295         * environments.[ch]:  Added.  Most of the credit for these files
2296         goes to Jost Boekemeier.
2297
2298 2000-08-25  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>
2299
2300         * procprop.c: #include "libguile/smob.h"; handle applicable smobs.
2301
2302 2000-08-24  Keisuke Nishida  <kxn30@po.cwru.edu>
2303
2304         * smob.h (scm_smob_descriptor): Added `apply' and `gsubr_type'.
2305         * smob.c (scm_make_smob_type): Initialize `apply' and `gsubr_type'.
2306         (scm_set_smob_apply): New function.
2307         (scm_smob_apply_0, scm_smob_apply_1, scm_smob_apply_2,
2308         scm_smob_apply_3): New functions.
2309         * eval.c (SCM_CEVAL, SCM_APPLY): Added dispatch for applicable smobs.
2310         * procs.c (scm_procedure_p): Check applicable smobs.
2311
2312 2000-08-24  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
2313
2314         * Makefile.am (BUILT_SOURCES): Experimentally added scmconfig.h
2315         also here.  (This is supposed to make sure that scmconfig.h is
2316         built before all sources in order to prevent that everything has
2317         to be rebuilt again.  Hope it works---I'm just guessing. :)
2318
2319         * fluids.c (scm_fluid_set_x): Return SCM_UNSPECIFIED.
2320
2321 2000-08-23  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
2322
2323         * gc.c (scm_gc_mark): Don't use GUILE_DEBUG flag to compile in
2324         extra tests.  (GUILE_DEBUG is only supposed to make extra
2325         debugging functions available.)
2326
2327 2000-08-21  Michael Livshin  <mlivshin@bigfoot.com>
2328
2329         * gc.h (SCM_GC_CARD_N_CELLS): change to be a nice non-confusing
2330         constant.
2331
2332 2000-08-19  Michael Livshin  <mlivshin@bigfoot.com>
2333
2334         * gc.c (scm_gc_sweep): added a `continue' statement that have
2335         fallen through the cracks in the merge.  thanks to Shuji Narazaki!
2336
2337         * gc.h: removed some stuff that broke compilation for people and
2338         wasn't actually needed anyway.
2339
2340 2000-08-18  Neil Jerram  <neil@ossau.uklinux.net>
2341
2342         * filesys.c (scm_fcntl): Docstring fix - missing newlines inserted.
2343
2344         * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_sethost,
2345         scm_setnet, setproto, setserv): Argument names changed to match
2346         doc string.
2347
2348         * feature.c (scm_program_arguments): New docstring.
2349
2350         * simpos.c (scm_getenv): Reflow docstring.
2351
2352         * eq.c (scm_eq_p, scm_eqv_p, scm_equal_p): Add texinfo markup to
2353         docstrings.
2354
2355         * chars.c (scm_char*): Docstring fixes - texinfo markup.
2356
2357 2000-08-18  Neil Jerram  <neil@ossau.uklinux.net>
2358
2359         * boolean.c (scm_not, scm_boolean_p): Docstring fixes - add
2360         texinfo markup and remove trailing newlines.
2361
2362 2000-08-17  Michael Livshin  <mlivshin@bigfoot.com>
2363
2364         this changes the Guile GC to use cards (aka "chunklets").
2365         (most of the ideas and some of the code are by Greg Harvey, though
2366         the code is probably unrecognizable now.  the original chunklet
2367         proposal, way back, is by Dale Jordan).
2368
2369         * tags.h: (SCM_GCTYPE16, SCM_GCCDR, SCM_GC[8]MARKP,
2370         SCM_SETGC[8]MARK, SCM_CLRGC[8]MARK): moved from here into gc.h.
2371         some (most) of these are probably going to be deprecated.
2372
2373         * gc.h (SCM_MARKEDP): simplified, there are no different mark bit
2374         locations anymore.
2375         (SCM_GC_CARD_*, SCM_C_BVEC_*): lots of new macros to deal with
2376         cards and bvecs (bit-vectors).
2377
2378         * gc.c: (scm_default_init_heap_size_*): defined to take cards into
2379         account, but keeping more or less the same values as previously.
2380         added some simple helper macros.
2381         (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK): defined to take cards
2382         into account.
2383         (BVEC_*, scm_mark_space_t, current_mark_space, mark_space_ptr,
2384         current_mark_space_offset, mark_space_head, get_bvec,
2385         clear_mark_space): new functions and supporting variables, types
2386         and macros that implement mark space management.
2387         (scm_igc): clear the mark space (all of it) before beginning the
2388         mark phase.
2389         (scm_gc_mark): changed the tests for rogue cells, much simplified
2390         throughout (no different mark bit locations to worry about now).
2391         (scm_mark_locations): don't consider card header cells.
2392         (scm_cellp): ditto.
2393         (scm_gc_sweep): simplified.
2394         (init_heap_seg): changed to take cards into account.
2395
2396 2000-08-16  Michael Livshin  <mlivshin@bigfoot.com>
2397
2398         * stime.c (scm_c_get_internal_run_time): new function, same as
2399         scm_get_internal_run_time but returns a long.  it's used by the GC
2400         for timekeeping, since with scm_get_internal_run_time there is a
2401         (extremely theoretical) possibility of consing.
2402         (scm_get_internal_run_time): redefined in terms of
2403         scm_c_get_internal_run_time.
2404
2405         * stime.h: added prototype for scm_c_get_internal_run_time.
2406
2407         * gc.c (scm_gc_stats): add more obscure stats, such as: mark time,
2408         sweep time, total marked cells, total swept cells, and number of
2409         times GC was invoked.
2410         (gc_start_stats): renamed from scm_gc_start, made static, taught
2411         to init the new stats.
2412         (gc_end_stats): renamed from scm_gc_end, made static, taught to
2413         calculate the new stats.
2414         (scm_igc): don't call gc_start_stats unless we are sure that we
2415         are indeed going to collect.  also, added some timekeeping between
2416         the mark and sweep phases.
2417         (scm_gc_sweep): count number of cells we sweep as we go.
2418
2419         * gc.h: removed prototypes for scm_gc_{start,end}.
2420
2421 2000-08-13  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>
2422
2423         * alist.c (scm_assq, scm_assv, scm_assoc): Report argument type
2424         error for the alist rather than the sublist where the type
2425         mismatch is discovered.
2426
2427 2000-08-13  Neil Jerram  <neil@ossau.uklinux.net>
2428
2429         * root.c (s_scm_call_with_dynamic_root): Docstring fix - rogue
2430         newline.
2431
2432 2000-08-12  Neil Jerram  <neil@ossau.uklinux.net>
2433
2434         * numbers.c (scm_ash): Docstring fix - missing newlines.
2435
2436         * ports.c (scm_port_filename): Docstring fix - missing newline.
2437
2438         * strports.c (scm_eval_string): Docstring fix - missing newline.
2439
2440         * vports.c (s_scm_make_soft_port): Docstring updated so that
2441         example is correct.
2442
2443         * strop.c: Docstring fixes - quotation marks and backslashes
2444         needed quoting.
2445
2446         * numbers.c (s_scm_logand): Docstring fix - "@end lisp" inserted.
2447
2448 2000-08-11  Neil Jerram  <neil@ossau.uklinux.net>
2449
2450         * macros.c: Remove surplus newlines from end of docstrings.
2451

2453         list-cdr-ref.
2454
2455         * keywords.c: Docstring improvements in conjunction with new
2456         reference manual doc on keywords.
2457
2458         * error.c (scm_error_scm): Fix texinfo syntax error in
2459         docstring.  (@code(~S) should be @code{~S}.)
2460
2461         * dynl.c: Remove surplus newlines from end of docstrings.
2462
2463 2000-08-11  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>
2464
2465         * eval.c (scm_eval): Backward incompatible change: Now takes an
2466         environment specifier as second arg.  `eval' hereby becomes R5RS
2467         compatible.
2468         (scm_i_eval_x, scm_i_eval): New functions (replace
2469         scm_eval_3).
2470         (scm_eval2, scm_eval_3): Deprecated.
2471         (scm_top_level_lookup_closure_var): Deprecated.
2472

2480         SCM_MODULE_EVAL_CLOSURE): New macros.
2481         (scm_module_index_obarray, scm_module_index_uses,
2482         scm_module_index_binder, scm_module_index_eval_closure): New
2483         constants; #include "validate.h".
2484
2485         * modules.c (scm_module_tag, scm_module_system_booted_p): New
2486         globals.
2487         (scm_post_boot_init_modules): Initialize scm_module_tag.
2488         (scm_interaction_environment): New primitive.

2497         to new scm_eval_x.

2499         * load.c (load): Use `scm_selected_module' to compute second arg
2500         to new scm_i_eval_x; Don't call it if module system hasn't booted.
2501         (scm_read_and_eval_x): Deprecated.
2502         #include "modules.h".
2503

2505         (scm_start_stack): Use scm_i_eval.
2506
2507         * strports.c: #include "modules.h".

2512 2000-08-09  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>
2513
2514         The following changes are intended to ensure that struct instances
2515         are freed before their vtables.  It's optimized for the most
2516         common case, which is freeing of struct instances.
2517
2518         * gc.c (scm_gc_mark, scm_gc_sweep): Remove vcell = 1 magic.
2519         (scm_structs_to_free): New variable.

2523         * struct.h (SCM_STRUCT_GC_CHAIN, SCM_SET_STRUCT_GC_CHAIN): New
2524         macros.
2525         (scm_structs_to_free, scm_struct_prehistory): Declare.
2526
2527         * struct.c (scm_make_struct, scm_make_vtable_vtable): Structs
2528         handles are now double cells; Initialize SCM_STRUCT_GC_CHAIN to
2529         0.
2530         (scm_struct_gc_init, scm_free_structs): New GC C hooks.
2531         (scm_struct_prehistory): Install them.

2541
2542         * iselect.c: Include <unistd.h>.  Thanks to Bertrand Petit!

2547         scm_make_vtable_vtable): Updated documentation.
2548
2549         * print.c (scm_simple_format): Bugfix: Coerce port before using
2550         it.
2551
2552 2000-07-31  Gary Houston  <ghouston@arglist.com>
2553
2554         * net_db.c: declare h_errno only if HAVE_H_ERRNO is not defined
2555         (thanks to Richard Kim for the bug report).
2556
2557 2000-07-30  Marius Vollmer  <mvo@zagadka.ping.de>
2558
2559         * alist.c (scm_assq_remove_x, scm_assv_remove_x,
2560         scm_assoc_remove_x): Use scm_delq1_x instead of scm_delq_x, since
2561         using the latter is pointless.
2562
2563 2000-07-26  Dirk Herrmann  <D.Herrmann@tu-bs.de>
2564
2565         * gc.c (scm_gc_sweep):  Renamed local variable from 'free' to
2566         'free_struct_data' to avoid confusion with stdlib's 'free'.

2569
2570         * vectors.c (scm_make_vector):  Fix the initialization order of
2571         the vector such that the type cell is initialized last.
2572
2573 2000-07-26  Dirk Herrmann  <D.Herrmann@tu-bs.de>
2574
2575         * struct.[ch] (scm_struct_init):  Made static.  Fixed not to rely
2576         on the struct cell to be fully initialized.
2577
2578         * struct.c (scm_make_struct, scm_make_vtable_vtable):  Fix the
2579         initialization order of the struct such that the type cell is
2580         initialized last.
2581
2582 2000-07-25  Marius Vollmer  <mvo@zagadka.ping.de>
2583
2584         * alist.c (scm_assq_remove_x, scm_assv_remove_x,
2585         scm_assoc_remove_x): Remove only the first cell with a matching
2586         key, not all.
2587
2588 2000-07-24  Marius Vollmer  <mvo@zagadka.ping.de>
2589
2590         * stime.c (scm_strftime): Recognize a return value of zero from
2591         strftime as buffer overflow and take care to detect a valid zero
2592         length result regardless.  Thanks to David Barts!
2593
2594 2000-07-23  Marius Vollmer  <mvo@zagadka.ping.de>
2595
2596         * alist.c (scm_assq_remove_x, scm_assv_remove_x,
2597         scm_assoc_remove_x): Remove all cells whose key is eq, eqv, or
2598         equal (respectively) to the argument key, not all cells that are
2599         eq, eqv, or equal to the first cell with the argument key.  Thanks
2600         to Neil Jerram!
2601
2602 2000-07-18  Dirk Herrmann  <D.Herrmann@tu-bs.de>
2603
2604         * gc.h (SCM_FREE_CELL_CDR, SCM_SET_FREE_CELL_CDR), hooks.c
2605         (make_hook), modules.c (OBARRAY, USES, BINDER):  Pack and unpack
2606         SCM values appropriately.
2607
2608         * modules.c (scm_standard_eval_closure):  Don't pass an inum to
2609         scm_makcclo, but rather a long value.
2610
2611 2000-07-18  Dirk Herrmann  <D.Herrmann@tu-bs.de>
2612
2613         read.c (scm_lreadrecparen), srcprop.c (scm_set_source_property_x):
2614         SCM_SETCDR and SCM_WHASHSET macros don't deliver a return value.
2615         Thanks to Han-Wen Nienhuys for the bug report.
2616
2617 2000-07-18  Dirk Herrmann  <D.Herrmann@tu-bs.de>
2618
2619         * root.[ch] (scm_call_catching_errors):  Deprecated.
2620

2622         standard initialization functions.
2623
2624 2000-07-17  Marius Vollmer  <mvo@zagadka.ping.de>
2625
2626         * eval.c (unmemocopy): Don't rely on V being a list of at least
2627         one element.  Thanks to Bill Schottstaedt!
2628
2629 2000-07-15  Michael Livshin  <mlivshin@bigfoot.com>
2630
2631         * gc.c (scm_done_free): new.
2632         expanded comments about scm_done_malloc.
2633
2634         * gc.h: added prototype for scm_done_free
2635
2636 2000-07-13  Dirk Herrmann  <D.Herrmann@tu-bs.de>
2637
2638         * gc.h (scm_take_stdin):  Removed.
2639
2640         * gc.h (SCM_VALIDATE_CELL):  Delegate cell checks to function
2641         scm_assert_cell_valid to allow extensions to the checking
2642         functionality without need to recompile everything.
2643
2644         * gc.[ch] (scm_assert_cell_valid, scm_set_debug_cell_accesses_x):
2645         Added as conditionally compiled functions for the case that
2646         SCM_DEBUG_CELL_ACCESSES is enabled.
2647
2648         * gc.c (debug_cells_p):  Added to indicate whether compile-time
2649         included cell access debugging is run-time enabled.
2650
2651         * gc.[ch] (scm_gc_running_p):  Added to indicate that scm_igc is
2652         being executed.  Intended to be used instead of scm_gc_heap_lock
2653         at most places.
2654
2655         * error.c (scm_error), gdbint.c (SCM_GC_P):  Use scm_gc_running_p
2656         instead of scm_gc_heap_lock.
2657
2658         * gc.c (scm_igc):  Set scm_gc_running_p to true while running.
2659
2660         * gc.c (scm_mark_locations):  Don't mark free cells.
2661
2662         * weaks.c (scm_scan_weak_vectors):  Use SCM_FREE_CELL_P instead of
2663         SCM_FREEP.
2664
2665 2000-07-13  Dirk Herrmann  <D.Herrmann@tu-bs.de>
2666
2667         * gc.c (scm_mark_locations):  Minimized some variable scopes and
2668         simplified the code a bit.
2669
2670 2000-07-10  Dirk Herrmann  <D.Herrmann@tu-bs.de>
2671
2672         * gc.h (SCM_SET_FREE_CELL_TYPE, SCM_SET_FREE_CELL_CDR,
2673         SCM_FREE_CELL_P, SCM_FREE_CELL_CDR):  Added since free cells
2674         should not be accessed via SCM_C[AD]R.  Further, using dedicated
2675         macros to access free cells allows all other cell accessing macros
2676         to treat acesses to free cells as errors, thus enabling better
2677         error checks for cell accesses.  SCM_FREE_CELL_P is supposed to
2678         replace SCM_FREEP some time.
2679
2680         * gc.h (SCM_NEWCELL, SCM_NEWCELL2), gc.c (map_free_list,
2681         free_list_length, scm_check_freelist, scm_debug_newcell,
2682         scm_debug_newcell2, freelist_length, scm_gc_for_newcell,
2683         scm_gc_mark, scm_gc_sweep, init_heap_seg):  Only use the dedicated
2684         cell accessors when accessing free cells.
2685
2686 2000-07-10  Dirk Herrmann  <D.Herrmann@tu-bs.de>
2687
2688         * gc.h (SCM_CELL_WORD, SCM_CELL_OBJECT):  Treat the referenced
2689         object as const in order to make the compiler warn about code like
2690         SCM_CELL_WORD (x, n) = y.  Instead, SCM_SET_CELL_WORD (x, n, y)
2691         should be used.
2692
2693         (SCM_CELL_WORD_LOC, SCM_CARLOC, SCM_CDRLOC):  Return the address
2694         as an address to a non-const object, since these macros are used
2695         to allow direct write access to objects.
2696
2697 2000-07-07  Dirk Herrmann  <D.Herrmann@tu-bs.de>
2698
2699         * hashtab.c (scm_hash_fn_create_handle_x):  Signal an error if the
2700         given hash table has no slots.
2701
2702 2000-07-06  Dirk Herrmann  <D.Herrmann@tu-bs.de>
2703
2704         * gc.c (policy_on_error):  Added in order to allow alloc_some_heap
2705         to react to malloc failures in a context dependent way.
2706
2707         (scm_check_freelist):  No need to flush streams before abort().
2708
2709         (scm_gc_for_newcell):  Try to allocate new memory in three phases:
2710         grow heap if preferred, if still no memory available collect
2711         garbage, if still no memory available grow heap.
2712
2713         (heap_segment_table_size):  Added to always reflect the actual
2714         size of the heap segment table, because scm_n_heap_segs may differ
2715         from the heap segment table size.
2716
2717         (alloc_some_heap):  In case of malloc failure, react according to
2718         the new policy_on_error parameter (either return to caller or
2719         abort immediately).  Further, keep heap_segment_table_size up to
2720         date.
2721
2722         (scm_init_storage):  Initialize heap_segment_table_size.
2723
2724 2000-07-06  Dirk Herrmann  <D.Herrmann@tu-bs.de>
2725
2726         * gh.h:  Don't include <stdio.h>.  Thanks to Han-Wen Nienhuys for
2727         the hint.
2728
2729 2000-06-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>
2730
2731         * __scm.h (SCM_OUTOFRANGE, SCM_NALLOC, SCM_HUP_SIGNAL,
2732         SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL, SCM_SEGV_SIGNAL,
2733         SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL, SCM_SIG_ORD,
2734         SCM_ORD_SIG, SCM_NUM_SIGS):  Re-introduce these as deprecated
2735         symbols.
2736
2737         * error.c (scm_wta):  Re-introduce dispatching for SCM_OUTOFRANGE
2738         and SCM_NALLOC, but as a deprecated feature.
2739
2740 2000-06-30  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
2741
2742         * debug.c: Added #include fluids.h.
2743
2744         * numbers.c (scm_gr_p, scm_leq_p, scm_geq_p): Turned into
2745         primitive generics.  (Thanks to Nicolas Neuss.)
2746
2747 2000-06-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>
2748
2749         * gc.c (alloc_some_heap):  Use scm_memory_error to indicate a
2750         failed attempt to get additional memory from the system.
2751
2752         (scm_gc_for_newcell):  Changed the control structure to make the
2753         behaviour explicit for the case that gc is not able to free any
2754         cells.
2755
2756 2000-06-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>
2757
2758         * __scm.h (SCM_OUTOFRANGE):  Removed.
2759
2760         * error.c (scm_wta):  Removed sick dispatch code for range
2761         errors.  (More sick dispatches still to be removed.)
2762
2763         * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
2764         scm_hash_fn_remove_x):  Eliminate redundant test for if unsigned
2765         value is non-negative.  Use scm_out_of_range to signal range
2766         errors.
2767
2768         * hooks.c (make_hook), unif.c (scm_aind):  Use scm_out_of_range to
2769         signal range errors.
2770
2771         * list.c (scm_list_ref, scm_list_set_x, scm_list_cdr_set_x):  Fix
2772         error reporting (now uses original input parameter to report wrong
2773         type argument errors).  Use SCM_OUT_OF_RANGE to report range
2774         errors and SCM_WRONG_TYPE_ARG to report type errors.
2775
2776         * strings.c (scm_substring):  Make range checks for negative
2777         values explicit (former behaviour relied on an implicit
2778         conversion from signed to unsigned).  Don't use SCM_ASSERT for
2779         range checks.
2780
2781         * unif.c (scm_aind, scm_transpose_array, scm_bit_set_star_x,
2782         scm_bit_count_star):  Use scm_out_of_range to signal range
2783         errors.
2784
2785         * unif.c (scm_transpose_array, scm_bit_position), vectors.c
2786         (scm_vector_ref, scm_vector_set_x, scm_vector_move_left_x,
2787         scm_vector_move_right_x):  Use SCM_ASSERT_RANGE to check ranges.
2788
2789 2000-06-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>
2790
2791         * validate.h (SCM_VALIDATE_INUM_MIN_COPY,
2792         SCM_VALIDATE_INUM_MIN_DEF_COPY, SCM_VALIDATE_INUM_RANGE_COPY):
2793         Perform all range checks based on the input value.  The former way
2794         of using the value that is assigned to the target variable fails
2795         if the assignment to the target variable itself can change the
2796         value because of type conversion.
2797
2798         (SCM_ASSERT_RANGE):  Use scm_out_of_range to signal range errors.
2799
2800 2000-06-30  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
2801
2802         * gc.c (scm_gc_for_newcell): Behave gracefully also if scm_igc
2803         doesn't yield any new cells.  In theory this could happen if all
2804         cells allocated with NEWCELL are either in use or conservatively
2805         marked and all cluster spine cells are conservatively marked.
2806         (Thanks to Dirk.)
2807
2808 2000-06-29  Dirk Herrmann  <D.Herrmann@tu-bs.de>
2809
2810         * __scm.h (SCM_NALLOC):  Removed.
2811
2812         * error.c (scm_wta):  Removed sick dispatch code for memory
2813         errors.  (More sick dispatches still to be removed.)
2814
2815         * numbers.c (scm_mkbig, scm_adjbig), ports.c (scm_make_port_type),
2816         random.c (scm_i_copy_rstate, scm_c_make_rstate), smob.c
2817         (scm_make_smob_type), srcprop.c (scm_make_srcprops), vectors.c
2818         (scm_vector_set_length_x):  Now using scm_memory_error to signal
2819         memory errors.
2820
2821 2000-06-29  Dirk Herrmann  <D.Herrmann@tu-bs.de>
2822
2823         * __scm.h:  Removed some commented code and fixed some comments.
2824
2825         (SCM_HUP_SIGNAL, SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL,
2826         SCM_SEGV_SIGNAL, SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL,
2827         SCM_SIG_ORD, SCM_ORD_SIG, SCM_NUM_SIGS):  Removed.
2828
2829         * async.c:  Removed some commented code.
2830
2831 2000-06-29  Dirk Herrmann  <D.Herrmann@tu-bs.de>
2832
2833         * gc.c (scm_gc_mark, scm_gc_sweep, scm_must_malloc,
2834         scm_must_realloc, scm_must_free, alloc_some_heap):  Use the
2835         appropriate error signalling function.
2836
2837 2000-06-29  Dirk Herrmann  <D.Herrmann@tu-bs.de>
2838
2839         * root.h (scm_first_type):  Removed.
2840
2841 2000-06-29  Dirk Herrmann  <D.Herrmann@tu-bs.de>
2842
2843         * gc.c (MIN_GC_YIELD):  Removed.
2844
2845 2000-06-28  Michael Livshin  <mlivshin@bigfoot.com>
2846
2847         * gc.c (scm_gc_for_newcell): don't try to do GC if it's blocked,
2848         allocate instead.
2849
2850 2000-06-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>
2851
2852         * async.c (scm_gc_async, scm_gc_vcell, scm_sys_gc_async_thunk):
2853         Moved to gc.c.
2854
2855         (scm_init_async):  Moved initialization for scm_gc_async and
2856         scm_gc_vcell to gc.c.  Moved initialization of scm_asyncs here
2857         from gc.c.
2858
2859         * async.h (scm_gc_async):  Not globally visible any more.
2860
2861         * gc.c (scm_gc_stats):  Made callable even from within regions
2862         where gc is blocked.
2863
2864         (scm_gc_end):  Eliminate the hardcoding of the marking of the
2865         scm_gc_async from the gc core.
2866
2867         (scm_init_storage):  Don't initialize the scm_asyncs list here.
2868         This is now done in asyncs.c.
2869
2870         (scm_gc_vcell):  Moved here from async.c.
2871
2872         (gc_async):  Renamed from scm_gc_async, moved here from async.c
2873         and made static.
2874
2875         (gc_async_thunk):  Renamed from scm_sys_gc_async_thunk and moved
2876         here from async.c.
2877
2878         (mark_gc_async):  New hook function for scm_after_gc_c_hook.
2879
2880         (scm_init_gc):  Added initialization of scm_gc_vcell and
2881         gc_async.  Further, add mark_gc_async to scm_after_gc_c_hook.
2882
2883         * init.c (scm_boot_guile_1):  scm_init_gc requires asyncs to be
2884         initialized.
2885
2886 2000-06-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>
2887
2888         * gc.c (scm_igc):  Removed commented code that once was intended
2889         to unprotect struct types with no instances.
2890
2891         * root.h (scm_type_obj_list):  Removed.
2892
2893 2000-06-27  Dirk Herrmann  <D.Herrmann@tu-bs.de>
2894
2895         * async.c (scm_init_async):  Switch to standard way of smob
2896         initialization.
2897
2898 2000-06-21  Michael Livshin  <mlivshin@bigfoot.com>
2899
2900         * guile-doc-snarf.in: use cut instead of sed, that's much much
2901         faster.  also, don't call basename more than needed.  and, to gain
2902         a couple of microseconds more, don't call cat needlessly.  (thanks
2903         to Brad Knotwell).
2904
2905 2000-06-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>
2906
2907         * guile-snarf.awk.in, guile-snarf.in, snarf.h:  Rename SCM__I to
2908         SCM_SNARF_INIT_START, SCM__D to SCM_SNARF_DOC_START, SCM__S to
2909         SCM_SNARF_DOCSTRING_START and SCM__E to SCM_SNARF_DOCSTRING_END.
2910
2911 2000-06-21  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
2912
2913         * eval.c, eval.h (scm_top_level_lookup_closure_var): Added.
2914         #include "libguile/fluids.h".
2915
2916         * eval.h (SCM_TOP_LEVEL_LOOKUP_CLOSURE): New macro which replaces
2917         SCM_CDR (scm_top_level_lookup_closure_var) everywhere.
2918
2919         * root.h (scm_top_level_lookup_closure_var,
2920         scm_system_transformer): Removed.  (It's no sense in having the
2921         *variable* be a "fluid".)
2922
2923         * root.c (mark_root): Removed marking of
2924         s->top_level_lookup_closure_var and s->system_transformer.
2925
2926         * modules.c (scm_selected_module): the_module is now a fluid.
2927
2928 2000-06-20  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
2929
2930         * gc.h, tags.h: Be kind to compilers which must see hash signs in
2931         column 0.  (Thanks to Ian Grant.)
2932
2933         * numbers.h: Put #ifdef HAVE_LONG_LONGS around declarations using
2934         the long_long type.  (Thanks to Bernard Urban.)
2935
2936 2000-06-20  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
2937
2938         * gc.c, gc.h (scm_default_init_heap_size_1,
2939         scm_default_min_yield_1, scm_default_init_heap_size_2,
2940         scm_default_min_yield_2, scm_default_max_segment_size): New global
2941         variables.  Can be customized by the application before booting
2942         Guile.  (We might want to be able to control these parameters
2943         dynamically through the "options interface" in the future, but
2944         note that that is additional functionality.  Here we're giving
2945         default values which the environment variables can override.)
2946
2947         * list.c (scm_cons_star): Updated comment.
2948
2949         * smob.h: Changed comments for scm_make_smob_type and
2950         scm_make_smob_type_mfpe, warning that the latter might be
2951         deprecated in a future release.
2952
2953 2000-06-19  Dirk Herrmann  <D.Herrmann@tu-bs.de>
2954
2955         * list.[ch] (scm_cons_star/cons*):  Renamed from
2956         scm_list_star/list*.
2957
2958         * list.[ch] (scm_list_star/list*):  Provided as a deprecated alias
2959         for scm_cons_star/cons*.
2960
2961         * gc.c (scm_protect_object):  Updated comment.
2962
2963         * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX):  Removed.
2964
2965         * tags.h (SCM_UNPACK_CAR, SCM_NDOUBLE_CELLP):  Removed.
2966
2967 2000-06-19  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
2968
2969         * init.c, init.h (scm_initialized_p): Renamed from `initialized'
2970         and made global.
2971
2972         * gdbint.c (gdb_print): Print warning instead of calling scm_write
2973         if Guile isn't yet initialized.
2974
2975         * print.c (scm_current_pstate, scm_make_print_state): Simplified
2976         tests, using the assumption that Guile has been initialized.
2977
2978 Sun Jun 18 14:45:21 2000  Greg J. Badros  <gjb@cs.washington.edu>
2979
2980         * print.c (s_scm_current_pstate): Do not segfault when the
2981         print_state_pool is unitialized in `current-pstate', and better
2982         verify its state before altering it in scm_make_print_state().
2983
2984 2000-06-18  Michael Livshin  <mlivshin@bigfoot.com>
2985
2986         * scmsigs.c (s_scm_sigaction): guard the SIGIOT case with an
2987         #ifdef -- it's missing on at least one platform.  (thanks to
2988         Jan Nieuwenhuizen).
2989
2990 2000-06-16  Dirk Herrmann  <D.Herrmann@tu-bs.de>
2991
2992         * list.c (list*):  Added documentation from common-list.scm.
2993
2994 2000-06-15  Dirk Herrmann  <D.Herrmann@tu-bs.de>
2995
2996         * gc.c (scm_unprotect_object):  The reference count is guaranteed
2997         to be a positive number.
2998
2999 2000-06-15  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
3000
3001         * eval.c: Updated comment above scm_map.
3002
3003 2000-06-14  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
3004
3005         * gc.c (scm_protect_object): Avoid looking up the object handle
3006         twice.
3007         (scm_unprotect_object): Abort if scm_unprotect_object is called on
3008         an unprotected object.
3009
3010 2000-06-14  Michael Livshin  <mlivshin@bigfoot.com>
3011
3012         * gc.c (scm_unprotect_object): fix a nasty typo bug (thanks to
3013         Dirk Herrmann).
3014
3015 2000-06-14  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
3016
3017         * socket.c (scm_getsockopt): Changed type for `optlen' from int to
3018         size_t.
3019         (scm_accept, scm_getsockname, scm_getpeername, scm_recvfrom):
3020         Ditto for `tmp_size'.
3021         (scm_addr_buffer_size): Changed type from int to size_t.
3022
3023         * random.c: #include <string.h>.  (Needed by memcpy.)
3024
3025         * guile-snarf.awk.in: Replace the dot_doc_file arg with "-",
3026         indicating stdin, instead of "" and don't reset ARGC.  This is a
3027         workaround for `nawk' in AIX 4.3 on RS6000 but, as far as I know,
3028         it is correct, and perhaps even better.
3029
3030 2000-06-14  Gary Houston  <ghouston@arglist.com>
3031
3032         * scmsigs.c (scm_init_scmsigs): if HAVE_SIGINTERRUPT is not
3033         defined, add SA_RESTART to the sigaction flags correctly
3034         (thanks to Dale P. Smith).
3035
3036 2000-06-13  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
3037
3038         * strings.c: #include <string.h>. (Thanks to Bill Schottstaedt.)
3039
3040         * net_db.c (scm_resolv_error): Only use macro NETDB_INTERNAL if
3041         defined. It isn't on sgi irix 5.3.  (Thanks to Bill Schottstaedt.)
3042
3043         * Makefile.am (.c.doc): Pipe output (the .x contents) to /dev/null.
3044
3045 2000-06-13  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
3046
3047         * fports.c (scm_setvbuf): Use `free' instead of `scm_must_free'
3048         since read and write buffers are allocated by `malloc'.
3049
3050         * Makefile.am: Removed old test code.
3051
3052         * gh_test_c.c, gh_test_repl.c: Removed.
3053
3054 2000-06-12  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
3055
3056         * iselect.c (SCM_NLONGBITS): Add workaround for the Sun 4.2
3057         compiler.
3058
3059         * inet_aton.c (inet_aton): Cast init value for `cp'.
3060
3061         * ramap.c (s_scm_array_fill_x): Cast `ve' properly in case
3062         `scm_tc7_uvect'.
3063
3064         * symbols.c (scm_intern_obarray_soft,
3065         scm_sysintern0_no_module_lookup): Cast `name' to unsigned char ptr
3066         in calls to scm_strhash.
3067
3068         * strports.c (st_resize_port): Substituted SCM_UCHARS for
3069         SCM_CHARS.
3070         (st_write): Cast argument to strncpy to char ptr.
3071         (scm_mkstrport): Substituted SCM_ROUCHARS for SCM_ROCHARS.
3072         (scm_strport_to_string): Cast argument to scm_makfromstr to char
3073         ptr.
3074
3075         * ports.c (scm_ungetc): Cast value to unsigned char ptr before
3076         storing in putback_buf.
3077         (scm_unread_string): Substituted SCM_ROCHARS for SCM_ROUCHARS.
3078
3079         * ioext.c (s_scm_read_line): Cast result of call to
3080         scm_do_read_line to unsigned char ptr.
3081
3082         * gdbint.c (SEND_STRING): Cast argument to char pointer.
3083
3084         * fports.c (fport_flush): Declare `ptr' as unsigned char (was
3085         char).
3086
3087         * Makefile.am (DOT_DOC_FILES): List doc-files explicitly.  (We
3088         shouldn't use Make rules which aren't supported by most Make
3089         programs.)
3090         (OMIT_DEPENDENCIES): Defined to "libguile.h ltdl.h".  (We don't
3091         want these dependencies recorded, since they would get bogus
3092         relative paths; libguile.h is only used in gh.h and guile.c.)
3093         (EXTRA_DOT_X_FILES, EXTRA_DOT_DOC_FILES): New variables.
3094         (guile-procedures.txt): Depend on EXTRA_DOT_DOC_FILES.
3095         (modinclude_HEADERS): Removed kw.h.
3096
3097         * guile-snarf.in: Change regexp "^SCM__I" --> "^ *SCM__I".
3098         (The preprocessor might insert spaces before the identifier.)
3099
3100         * snarf.h (SCM_SNARF_HERE, SCM_SNARF_INIT, SCM_SNARF_DOCS):
3101         Renamed from SCM_HERE, SCM_INIT, SCM_DOCS.
3102
3103         * smob.h (scm_smobfuns): Removed deprecated type.
3104
3105         * smob.c, smob.h (scm_newsmob): Removed deprecated function.
3106         (Replaced by `scm_make_smob_type'.)
3107
3108         * keywords.c (scm_tc16_kw): Removed deprecated type.
3109         (Replaced by scm_tc16_keyword.)
3110
3111         * kw.h: Removed deprecated header file.
3112
3113         * evalext.c (serial-map): Removed deprected alias for scm_map.
3114         (Has been replaced by `map-in-order'.)
3115
3116         * ramap.c (serial-array-copy!, serial-array-map!): Removed
3117         depracted aliases.  (Replaced by `array-copy-in-order!' and
3118         `array-map-in-order'.)
3119
3120 2000-06-11  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
3121
3122         * gc.h (SCM_VALIDATE_CELL): Rewritten.
3123         (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
3124         SCM_SET_CELL_OBJECT): Use new version of SCM_VALIDATE_CELL.
3125         (Thanks to Han-Wen Nienhuys.)
3126
3127 2000-06-10  Michael Livshin  <mlivshin@bigfoot.com>
3128
3129         * guile-doc-snarf.in: don't pipe the CPP output right into sed --
3130         write it to the temp file first and check the CPP return code.
3131         (I introduced this bug earlier, and this probably caused people
3132         with non-GNU C preprocessors to get empty *.x files and not to
3133         have the build fail right away...).
3134
3135         * scmsigs.c (s_scm_sigaction): guard the SIGSYS case with an ifdef
3136         -- at least my libc5-based Linux system doesn't define SIGSYS.
3137
3138 2000-06-08  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
3139
3140         * snarf.h, guile-snarf.awk.in, guile-snarf.in: Replaced snarf
3141         markers with identifiers (SCM__I, SCM__D, SCM__S, SCM__E).
3142         (Thanks to Bernard Urban.)
3143
3144 2000-06-06  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
3145
3146         * modules.c (scm_system_module_env_p): Fixed detection of system
3147         modules.
3148
3149 2000-06-06  Marius Vollmer  <mvo@zagadka.ping.de>
3150
3151         * scmsigs.c (scm_sigaction): Silently ignore setting handlers for
3152         `program error signals' because they can't currently be handled by
3153         Scheme code.
3154
3155 2000-06-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3156
3157         * procs.h (SCM_SET_SUBRF):  Added.
3158
3159         * procs.c (scm_make_subr_opt):  Don't assign to SCM_SUBRF, use
3160         SCM_SET_SUBRF instead.  Thanks to Bernard Urban for the bug
3161         report.
3162
3163 2000-06-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3164
3165         * gc.h (SCM_CARLOC, SCM_CDRLOC):  Don't take the address of a SCM
3166         value.
3167
3168         * sort.c (scm_sorted_p, scm_merge, scm_merge_list_x,
3169         scm_merge_list_step):  Don't take the address of SCM_CAR.  Use
3170         SCM_CARLOC instead.  Thanks to Bernard Urban for the bug report.
3171
3172 2000-06-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3173
3174         * boolean.h (SCM_TRUE_P):  Removed, as people might use it as a
3175         replacement for !SCM_FALSEP.
3176
3177         * backtrace.c (display_error_body), boolean.h (SCM_BOOLP), gc.c
3178         (scm_unhash_name), gh_data.c (gh_module_lookup), load.c
3179         (scm_primitive_load), print.c (scm_simple_format), procs.c
3180         (scm_procedure_documentation), procs.h (SCM_TOP_LEVEL), ramap.c
3181         (scm_array_fill_int), scmsigs.c (scm_sigaction), stacks.c
3182         (narrow_stack, scm_make_stack, scm_stack_id), symbols.c
3183         (scm_string_to_obarray_symbol), throw.c (scm_catch,
3184         scm_lazy_catch, scm_ithrow), unif.c (scm_make_uve, scm_array_p,
3185         scm_array_set_x, scm_bit_set_star_x, scm_bit_count_star),
3186         validate.h (SCM_VALIDATE_BOOL_COPY, SCM_VALIDATE_PROC):  Replace
3187         uses of SCM_TRUE_P (x) with SCM_EQ_P (x, SCM_BOOL_T).
3188
3189 2000-06-04  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
3190
3191         * eval.c (scm_badformalsp): New static function.
3192         (SCM_CEVAL): Check arguments for procedure-with-setter closures.
3193         (Thanks to Keisuke Nishida.)
3194
3195         The major reason for Guile's slow loading speed has been the fact
3196         that a chain of Scheme level procedures has been evaluated for
3197         every top-level symbol lookup during the first pass through the
3198         code.
3199
3200         The following is a kludge which I suggested four years ago, and
3201         which I've repeatedly suggested since.  Personally, I've never
3202         been bothered by Guile's slow loading speed, so I thought I would
3203         let someone else do it...
3204
3205         But since the new environments will be included first in
3206         Guile-1.5, I thought it would make people happy to get the kludge
3207         into 1.4.
3208
3209         * modules.c: Added #include "libguile/vectors.h";
3210         Added #include "libguile/hashtab.h";
3211         Added #include "libguile/struct.h";
3212         Added #include "libguile/variable.h";
3213         Capture Scheme level `module-make-local-var!' to be used in the
3214         standard eval closure.
3215         (scm_standard_eval_closure): New primitive.
3216
3217         * modules.h (scm_standard_eval_closure): Declare.
3218
3219         * eval.c (scm_lookupcar): Test for !SCM_CONSP (SCM_CAR (env))
3220         instead of SCM_TRUE (scm_procedurep (SCM_CAR (env))).
3221
3222         * symbols.c (scm_sym2vcell): Bypass dispatch in the evaluator for
3223         standard eval closures.
3224
3225         * variable.c: Code layout fixes.
3226
3227 2000-06-03  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
3228
3229         * Makefile.am: Added LIBS line to libpath which accidentally
3230         disappeared in the change of 2000-06-01.
3231         (Thanks to Dale P. Smith.)
3232
3233 2000-06-03  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
3234
3235         * scmsigs.c (scm_segfault): Removed.  (Was probably added by
3236         mistake since it is not mentioned in ChangeLog.)
3237
3238         * gc.h (SCM_VALIDATE_CELL): Cast result to (void) in order to
3239         avoid compiler warnings in gcc.  (Does this work for other
3240         compilers?)
3241
3242 2000-06-03  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
3243
3244         * gc.h (SCM_VALIDATE_CELL): Don't "use" the value returned by
3245         abort ().
3246         (SCM_CARLOC, SCM_CDRLOC): Define directly instead of using
3247         SCM_CELL_OBJECT_0 and SCM_CELL_OBJECT_1.  It's not correct to take
3248         the address of these expressions since they use SCM_VALIDATE_CELL.
3249         (Thanks to Bernard Urban.)
3250
3251         * dynl.c: Changed #include <ltdl.h> --> #include
3252         "libltdl/ltdl.h".  (Thanks to Bill Schottstaedt.)
3253
3254 2000-06-01  Craig Brozefsky  <craig@red-bean.com>
3255
3256         * Makefile.am: libguile_la_LDFLAGS gets -version-info args
3257         from GUILE-VERSION definition of LIBGUILE version.  Added to
3258         libpath.h definitions for guileversion and libguileversion which
3259         both get their values from GUILE-VERSION definition.
3260
3261 2000-05-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3262
3263         * numbers.h (SCM_BIGP):  Don't use SCM_SMOB_PREDICATE in header
3264         file:  Code using numbers should not be required to include
3265         smob.h.
3266
3267 2000-05-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3268
3269         * coop-threads.c.cygnus, coop-threads.h.cygnus, fsu-pthreads.h,
3270         mit-pthreads.c, mit-pthreads.h:  Deleted.
3271
3272         * Makefile.am (EXTRA_DIST), scmsigs.c, threads.[ch]:  Drop
3273         references to deleted files and fsu/mit thread support in
3274         general.
3275
3276 2000-05-29  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3277
3278         * hooks.c (symbol_name, scm_create_hook):  Restored the original
3279         behaviour of scm_create_hook.  Changing it was bad as Carl
3280         R. Witty has pointed out.
3281
3282         * gc.c (scm_init_gc):  We can still rely on scm_create_hook to
3283         protect the object.
3284
3285 2000-05-26  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3286
3287         * gc.c (scm_init_gc):  Protect scm_after_gc_hook, since this will
3288         soon not be done by scm_create_hook any longer.
3289
3290         * hooks.c (make_hook, print_hook, scm_create_hook,
3291         scm_make_hook_with_name, scm_make_hook), hooks.h (SCM_HOOK_NAME,
3292         SCM_HOOK_PROCEDURES, SCM_SET_HOOK_PROCEDURES,
3293         scm_make_hook_with_name), init.c (scm_boot_guile_1):  Hooks no
3294         longer have names.  As an intermediate solution, the name
3295         predicate is emulated via object properties, but use of this
3296         feature is deprecated.
3297
3298         * hooks.h (scm_free_hook):  Removed, as it is never defined.
3299
3300 2000-05-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3301
3302         * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_FIXABLE):
3303         Un-deprecated since otherwise user code can't determine whether a
3304         number fits into an inum any longer.  The names should be changed
3305         some time, though.
3306
3307         * numbers.c (scm_big2inum):  Eliminated use of SCM_UNEGFIXABLE.
3308
3309         * tags.h (SCM_UNPACK_CAR):  Deprecated.
3310
3311 2000-05-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3312
3313         * filesys.h (SCM_OPDIRP), fluids.h (SCM_FLUIDP, SCM_FLUID_NUM),
3314         fports.h (SCM_OPFPORTP, SCM_OPINFPORTP, SCM_OPOUTFPORTP), hooks.h
3315         (SCM_HOOK_ARITY), keywords.h (SCM_KEYWORDP, SCM_KEYWORDSYM),
3316         numbers.h (SCM_NUMP, SCM_BIGSIGN, SCM_BDIGITS, SCM_NUMDIGS):
3317         Replace SCM_UNPACK_CAR appropriately.  Don't access cells via
3318         SCM_{SET}?C[AD]R unless they are known to be cons cells.
3319
3320         * gc.c (scm_heap_seg_data_t, scm_mark_locations, scm_cellp,
3321         init_heap_seg):  Remove unused struct member variable 'valid'.
3322
3323 2000-05-24  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3324
3325         * fports.c (fport_write), ports.c (scm_markstream, scm_port_mode,
3326         scm_print_port_mode), ports.h (SCM_OPPORTP, SCM_OPINPORTP,

3328         procs.h (SCM_CLOSCAR), unif.h (SCM_ARRAY_NDIM, SCM_ARRAY_CONTP),
3329         variable.h (SCM_VARIABLEP):  Replace SCM_UNPACK_CAR
3330         appropriately.
3331
3332 2000-05-23  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3333
3334         * gc.c (free_list_length), hash.c (scm_hasher), macros.c
3335         (scm_macro_type), objects.c (scm_class_of), options.c
3336         (scm_options), print.c (scm_iprin1), strports.c (st_seek), throw.c
3337         (SCM_LAZY_CATCH_P):  Replace SCM_UNPACK_CAR appropriately.
3338
3339 2000-05-23  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3340
3341         * eval.c (scm_macroexp, SCM_CEVAL, scm_force), tags.h:  Replace
3342         SCM_UNPACK_CAR with SCM_CELL_TYPE or SCM_CELL_WORD_0.
3343
3344         * eval.c (scm_force):  Add documentation.
3345
3346         * eval.c (scm_force, scm_cons_source):  Don't access cells via
3347         SCM_{SET}?C[AD]R unless they are known to be cons cells.
3348
3349 2000-05-23  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3350
3351         * strings.h (SCM_NSTRINGP, SCM_NRWSTRINGP), tags.h
3352         (SCM_NDOUBLE_CELLP), vectors.h (SCM_NVECTORP):  Deprecated.
3353
3354         * gc.c (scm_igc), gc.h (SCM_PTR_MASK, SCM_PTR_LT):  Removed #ifdef
3355         nosve #endif conditionally compiled code.
3356
3357 2000-05-23  Michael Livshin  <mlivshin@bigfoot.com>
3358
3359         * gc.c (scm_heap_seg_data_t): fixed comment for the `span' member.
3360
3361 2000-05-22  Michael Livshin  <mlivshin@bigfoot.com>
3362
3363         * guile-doc-snarf.in: put the preprocessed file through sed to
3364         trim all lines to 1024 chars.  I hope it doesn't break anybody's
3365         sed.  we'll see.  (note: this is lossy trimming, i.e. the spill
3366         isn't wrapped around but actually chopped off.  this seemed to me
3367         safe because the current snarfer doesn't understand multi-line
3368         cookies anyway.  in the long term, it would be nice not to depend
3369         on AWK for anything.)
3370
3371         * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): reverted
3372         the previous change to this macros, after deciding to torture the
3373         snarfer instead.
3374
3375 2000-05-21  Michael Livshin  <mlivshin@bigfoot.com>
3376
3377         * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): brought
3378         the yucky, ugly and nasty conditional compilation back.  sorry,
3379         but it was either that or requiring GAWK to build Guile.
3380         (lots of places): removed the code that implemented the old GC
3381         scheme.
3382
3383         * init.c (scm_boot_guile_1): removed the code conditioned on
3384         !GUILE_NEW_GC_SCHEME.
3385
3386         * __scm.h: (GUILE_NEW_GC_SCHEME): removed.
3387
3388         * gc.c (scm_protect_object, scm_unprotect_object): change the
3389         implementation to more efficient (at least in the time complexity
3390         sense).  the calls should now also be thread-safe -- I suspect
3391         that people expect them to be.  (thanks to Han-Wen Nienhuys)
3392         (lots of places): removed the code that implemented the old GC
3393         scheme.
3394
3395         * hashtab.c (scm_hash_fn_create_handle_x): add missing
3396         SCM_REALLOW_INTS before return.  I really wonder about the
3397         possible interactions between hashtables, threads & GC.  it
3398         doesn't look healthy at all.
3399
3400 2000-05-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3401
3402         * unif.c (scm_bit_count):  Fixed the parameter checks.  Thanks to
3403         Dale P. Smith.
3404
3405 2000-05-19  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3406
3407         * __scm.h (SCM_DEBUG_CELL_ACCESSES), gc.h (SCM_):  Added as a new
3408         debug option to verify all accesses to cells actually access
3409         objects on the heap.
3410
3411         * gc.h (SCM_VALIDATE_CELL):  Added.  Only performs validation if
3412         SCM_DEBUG_CELL_ACCESSES is set to 1.
3413
3414         (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
3415         SCM_SET_CELL_OBJECT):  Use SCM_VALIDATE_CELL to check every cell
3416         that is accessed.
3417
3418 2000-05-19  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3419
3420         * gh_data.c (gh_scm2chars, gh_scm2shorts, gh_scm2longs,
3421         gh_scm2floats, gh_scm2doubles):  Change !SCM_NIMP to SCM_IMP.
3422
3423         * gc.c (scm_cellp):  Fixed and simplified.
3424
3425         * throw.c (JBJMPBUF, SETJBJMPBUF, SCM_JBDFRAME, SCM_SETJBDFRAME,
3426         make_jmpbuf, scm_init_throw):  Now using double cells to represent
3427         jump buffers when using debug extensions.
3428
3429         (freejb):  Removed.
3430
3431 2000-05-18  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3432
3433         * gh.h gh_data.c gh_funcs.c (gh_new_procedure*, gh_chars2byvect,
3434         gh_shorts2svect, gh_longs2ivect, gh_ulongs2uvect, gh_floats2fvect,
3435         gh_doubles2dvect, gh_doubles2scm, gh_define, gh_lookup,
3436         gh_module_lookup):  Accept const pointers as parameters.
3437
3438         * gh.h gh_data.c (gh_int2scmb):  Deprecated.
3439
3440 2000-05-18  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3441
3442         * __scm.h (SCM_DEBUG_REST_ARGUMENT):  Renamed from
3443         SCM_DEBUG_REST_ARGUMENTS in order to clarify that we don't test
3444         the actual arguments in the list, but rather the rest argument as
3445         a list of arguments.
3446
3447         * validate.h (SCM_VALIDATE_REST_ARGUMENT):  Added.
3448
3449         * async.c (scm_noop), eval.c (scm_map, scm_for_each), list.c
3450         (scm_list_star, scm_append, scm_append_x), ports.c

3457         scm_dynamic_link, scm_init_dynamic_linking), dynl.h
3458         (scm_dynamic_link):  Removed possibility to pass flags to
3459         scm_dynamic_link, as it had no effect anyway.
3460
3461         * filesys.c (scm_fcntl):  Made single optional rest argument into
3462         a standard optional argument.
3463
3464         * hooks.c (scm_run_hook):  A list of rest arguments is never
3465         SCM_UNBNDP.
3466
3467         * list.c (scm_append, scm_append_x), stacks.c (scm_make_stack),
3468         strings.c (scm_string_append):  Don't perform half-hearted checks
3469         to see whether the rest argument forms a proper list any more, use
3470         SCM_VALIDATE_REST_ARGUMENTS instead.
3471
3472         * ports.c (scm_close_all_ports_except):  Accept empty list of rest
3473         arguments.
3474
3475         * posix.c (scm_convert_exec_args), print.c (scm_simple_format):
3476         Simplify verification of rest argument.
3477
3478         * stacks.c (scm_make_stack), stacks.h (scm_make_stack), throw.c
3479         (ss_handler, handler_message):  Make first mandatory rest argument
3480         of scm_make_stack into a standard mandatory argument.
3481
3482         * unif.c (scm_transpose_array, scm_enclose_array,
3483         scm_array_in_bounds_p), unif.h (scm_transpose_array,
3484         scm_enclose_array, scm_array_in_bounds_p):  Make first mandatory
3485         rest argument into a standard mandatory argument.
3486
3487 2000-05-17  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3488
3489         * __scm.h:  Added SCM_DEBUG as default debug option. (Thanks to
3490         Keisuke Nishida for the suggestion.)  Added debug option
3491         SCM_DEBUG_REST_ARGUMENTS.
3492
3493         * eval.c (scm_map, scm_for_each):  Make sure all lists have the
3494         same length.  Also, removed redundant parameter checks.
3495
3496 2000-05-16  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3497
3498         * Makefile.am:  Let 'make clean' remove *.x and *.doc files.
3499
3500         * __scm.h:  Improved explanation of giving options to make.
3501
3502         * __scm.h (SCM_DEBUG_TYPING_STRICTNESS), tags.h
3503         (SCM_STRICT_TYPING, SCM_DEBUG_TYPING_STRICTNESS):  Renamed
3504         SCM_STRICT_TYPING to SCM_DEBUG_TYPING_STRICTNESS and moved the
3505         corresponding declaration and comment to __scm.h.
3506
3507         * _scm.h (errno), gc.h (SCM_CELLPTR, SCM_PTR_LT), numbers.c
3508         (scm_remainder, scm_modulo), numbers.h (SCM_SRS, SCM_MAKINUM,
3509         SCM_INUM):  Removed conditionally compiled code for Turbo C.
3510
3511         * gdbint.c (gdb_maybe_valid_type_p):  Eliminated call to scm_tag.
3512         That check can be assumed to be redundant except for very rare
3513         conditions that actually indicate broken heap data.
3514
3515 2000-05-16  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3516
3517         * numbers.c (scm_logcount, scm_integer_length):  Reordered
3518         dispatch sequence.
3519
3520 2000-05-15  Gary Houston  <ghouston@arglist.com>
3521
3522         * stime.c (scm_strftime): don't reset TZ if zone is an empty
3523         string.  append a "0" to the zone for TZ.
3524
3525 2000-05-15  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3526
3527         * numbers.c (scm_logbit_p, scm_bit_extract):  Reordered dispatch
3528         sequence.

3542         (scm_tc16_flo, scm_tc_flo, scm_tc_dblr, scm_tc_dblc):  Wrapped
3543         deprecated code between #if (SCM_DEBUG_DEPRECATED == 0) #endif.
3544
3545         * fports.c (scm_fport_buffer_add), ports.c (scm_input_port_p,
3546         scm_output_port_p), print.c (scm_get_print_state), validate.h
3547         (SCM_VALIDATE_CHAR):  Replace use of deprecated macros
3548         SCM_INPORTP, SCM_OUTPORTP, SCM_ICHRP by SCM_INPUT_PORT_P,
3549         SCM_OUTPUT_PORT_P, SCM_CHARP, respectively.
3550
3551 2000-05-14  Gary Houston  <ghouston@arglist.com>
3552
3553         * stime.c (scm_strftime): if HAVE_TM_ZONE is not defined, hack the
3554         TZ environment variable so that the %Z format returns the zone
3555         from the input vector instead of the system default.
3556
3557         from Keisuke Nishida:
3558         * fports.c (scm_setvbuf): minor docstring fix.
3559         * ports.h (scm_generic_fgets): obsolete prototype deleted.
3560
3561 2000-05-11  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3562
3563         * __scm.h:  Added new section for debugging options.
3564
3565         (SCM_DEBUG_DEPRECATED):  If 1, no deprecated code is included to
3566         help developers to get rid of references to deprecated code.
3567
3568         * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_UNEGFIXABLE,
3569         SCM_FIXABLE, SCM_FLOBUFLEN):  These macros are no longer provided
3570         as part of the interface and are marked as deprecated in the
3571         header file.
3572
3573         * numbers.c (scm_make_real, scm_make_complex):  Inlined the
3574         corresponding macros SCM_NEWREAL and SCM_NEWCOMPLEX,
3575         respectively.
3576
3577         * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX, SCM_INEXP, SCM_CPLXP,

3584         SCM_SET_CELL_WORD, SCM_SET_CELL_OBJECT):  Scheme cells now consist
3585         of two scm_bits_t values instead of two SCM values, because it is
3586         legal for cell entries to hold values that are not scheme objects.
3587
3588         (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR):
3589         Use SCM_SETC[AD]R to modify contents of pairs.
3590

3592
3593         * numbers.c (IS_INF, isfinite):  Added FIXME comment.
3594
3595         (scm_abs, scm_magnitude):  Make these two independent of each
3596         other.  scm_abs now reports an error if given a complex argument.
3597
3598         (scm_istr2flo, scm_integer_p).  Use SCM_REAL_VALUE instead of
3599         SCM_REALPART if the object is known to be real.
3600
3601         (scm_init_numbers):  No need to use SCM_NEWREAL macro for speed
3602         here.
3603
3604         * numbers.h (SCM_SINGP):  Set to 0 instead of SCM_BOOL_F.

3606 2000-05-10  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3607
3608         * eq.c (scm_eqv_p):  Separate handling of real and complex
3609         values.  Remove #ifdef SCM_BIGDIG #endif test.

3612         gh_scm2doubles), hash.c (scm_hasher), ramap.c (scm_array_fill_int,
3613         ramap_rp, scm_array_map_x), random.c (vector_scale,
3614         vector_sum_squares), unif.c (scm_make_uve, scm_array_p,
3615         scm_array_set_x):  Use SCM_REAL_VALUE instead of SCM_REALPART if
3616         the object is known to be real.  Use SCM_COMPLEXP instead of
3617         deprecated SCM_CPLXP.  Use SCM_INEXACTP instead of deprecated
3618         SCM_INEXP.
3619
3620 2000-05-10  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3621
3622         * numbers.c:  No need to include unif.h.
3623
3624         (IS_INF):  Returned to old test for now:  x == x + 1 will not work
3625         for large numbers due to rounding errors.
3626         Thanks to Kalle Olavi Niemitalo.
3627
3628 2000-05-09  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3629
3630         * numbers.c (scm_divbigdig):  Removed outdated comment.

3632         (scm_number_to_string, scm_string_to_number, scm_number_p,
3633         scm_real_p, scm_integer_p, scm_inexact_p, scm_gr_p, scm_leq_p,
3634         scm_geq_p, scm_make_rectangular, scm_make_polar,

3638
3639 2000-05-09  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3640
3641         * numbers.c (IS_INF):  The new test is x == x + 1.  The old test
3642         x == x/2 did not work for zero values.  Thanks to Han-Wen Nienhuys
3643         and Ivan Toshkov.
3644
3645         (scm_number_to_string, scm_sum, scm_difference, scm_two_doubles,
3646         scm_num2long, scm_num2long_long, scm_num2ulong):  Reordered
3647         dispatch sequence.
3648
3649 2000-05-09  Marius Vollmer  <mvo@zagadka.ping.de>
3650
3651         * scmsigs.c (take_signal): Execute SCM_ASYNC_TICK for SIGSEGV,
3652         SIGILL and SIGBUS signals.  These signals are not continuable and
3653         must be handled for real right away.
3654
3655 2000-05-08  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3656
3657         * numbers.c (scm_zero_p, scm_positive_p, scm_negative_p,
3658         scm_real_part, scm_imag_part, scm_magnitude,
3659         scm_inexact_to_exact):  Reordered dispatch sequence.
3660
3661 2000-05-08  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3662
3663         * feature.c:  No need to include "libguile/smob.h"
3664
3665         (scm_loc_features, features, scm_add_feature, scm_init_feature):
3666         Removed variable 'scm_loc_features' as a pointer to the SCM value
3667         holding the features list.  Using variable 'features' instead,
3668         which holds the interned pair.  Thus, SCM_SETCDR can be used
3669         instead of pointer trickery.
3670
3671 2000-05-08  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3672
3673         * alist.c (scm_acons):  Use SCM{_SET}?_CELL_OBJECT as long as a
3674         cell is not known to be a valid pair.
3675
3676 2000-05-08  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3677
3678         * eval.c (ASRTSYNTAX, scm_m_body, scm_m_letrec1):  Removed
3679         ASRTSYNTAX.  Using SCM_ASSYNT instead.
3680
3681         (scm_m_body):  Don't create a redundant cons cell.
3682
3683         (scm_m_do):  Removed redundant test 'bodycheck'.
3684
3685         (bodycheck):  Removed.
3686
3687         * stacks.c (stack_depth, read_frame, read_frames):  Removed
3688         redundant calculation of size, minimized some variable scopes.
3689
3690 2000-05-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3691
3692         * pairs.c (scm_cons, scm_cons2):  Use SCM{_SET}?_CELL_OBJECT as
3693         long as a cell is not known to be a valid pair.
3694
3695         (scm_pair_p):  Eliminated redundant SCM_IMP test.
3696
3697 2000-05-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3698
3699         * eval.c (scm_m_body, scm_macroexp, unmemocopy, scm_eval_args,
3700         scm_deval_args):  Eliminated redundant SCM_IMP tests.
3701
3702         * hashtab.c (scm_ihashx, scm_sloppy_assx, scm_delx_x), weaks.c
3703         (scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
3704         scm_make_doubly_weak_hash_table):  Fixed critical sections.
3705         Thanks to Keisuke Nishida.
3706
3707 2000-05-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3708
3709         * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest):
3710         Fixed some goto-related initialization bugs (introduced by me).
3711
3712 2000-05-04  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3713
3714         * numbers.h (SCM_INUM0):  Uses SCM_MAKINUM instead of SCM_PACK.
3715
3716         * dynl.c (dynl_obj, DYNL_OBJ, get_dynl_obj):  Removed.
3717
3718         (DYNL_FILENAME, DYNL_HANDLE):  Use SCM_CELL... macros instead of
3719         pointer trickery.
3720
3721         (SET_DYNL_HANDLE):  Added.
3722
3723         (scm_dynamic_object_p):  Simplified.
3724
3725         (scm_dynamic_unlink, scm_dynamic_func):  Changed comment.  Deliver
3726         better error message when accessing unlinked dynamic objects.
3727         Eliminated call to get_dynl_obj.
3728
3729 2000-05-03  Marius Vollmer  <mvo@zagadka.ping.de>
3730
3731         * scmsigs.c (orig_handlers) [!HAVE_SIGACTION]: Fix declaration to
3732         be an array of function pointers instead of being a pointer to an
3733         array returning function.  Thanks to Kalle Olavi Niemitalo!
3734
3735 2000-05-03  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3736
3737         * numbers.c (scm_divbigbig, scm_divbigint), numbers.h
3738         (scm_divbigbig, scm_divbigint):  Don't return zero any more to
3739         indicate that a division has a remainder, return SCM_UNDEFINED
3740         instead.  It is improbable that anyone actually used these
3741         functions outside of numbers.c.  For this reason and due to the
3742         change in behaviour the functions are static now.  Thus, if
3743         surprisingly there are users of these functions they will at least
3744         get alarmed.
3745
3746         * numbers.c:  Removed #ifdef SCM_BIGDIG #endif in those functions,
3747         that already have a clean dispatch order.  Note: SCM_BIGDIG is
3748         always defined.
3749
3750         * numbers.c (scm_inexact_p):  Simplified.
3751
3752         * numbers.c (scm_num_eq_p, scm_less_p, scm_max, scm_min,
3753         scm_product, scm_num2dbl, scm_angle):  Reordered dispatch
3754         sequence, thereby fixing some comparisons of SCM values with
3755         integer constants.
3756
3757         * numbers.c (scm_divide):  Division by zero of inums leads to an
3758         error now.  (Formerly, an infinite number was returned.)
3759
3760         Respect the fact, that scm_divbigbig does now return SCM_UNDEFINED
3761         if a division has a remainder.
3762
3763 2000-05-02  Gary Houston  <ghouston@arglist.com>
3764
3765         * Makefile.am (INCLUDES): add ${INCLTDL} (thanks to Tim Mooney).
3766
3767 2000-05-02  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3768
3769         * numbers.c (scm_logtest, scm_division):  Reordered dispatch
3770         sequence, thereby fixing some comparisons of SCM values with
3771         integer constants.
3772
3773         * numbers.h (scm_makdbl):  Mark as deprecated at the point of
3774         declaration.
3775
3776         * eval.c (SCM_CEVAL, SCM_APPLY), gh_data.c (gh_double2scm,
3777         gh_doubles2scm), numbers.c (scm_istr2flo, scm_max, scm_min,
3778         scm_sum, scm_difference, scm_product, scm_divide, scm_sys_expt,
3779         scm_sys_atan2, scm_make_rectangular, scm_make_polar,
3780         scm_real_part, scm_imag_part, scm_magnitude, scm_angle,
3781         scm_long2num, scm_long_long2num, scm_ulong2num), ramap.c
3782         (ramap_rp, scm_array_map_x), random.c (scm_random,
3783         scm_random_uniform, scm_random_normal_vector_x, scm_random_exp),
3784         struct.c (scm_struct_ref), unif.c (scm_array_to_list):  Replace
3785         call to scm_makdbl with a call to scm_make_real or
3786         scm_make_complex, depending on whether the imaginary part is known
3787         to be zero.
3788
3789 2000-05-01  Gary Houston  <ghouston@arglist.com>
3790
3791         * scmsigs.c: fix the definition of orig_handlers for the case
3792         that HAVE_SIGACTION is not defined (thanks to
3793         Kalle Olavi Niemitalo).
3794
3795         * Makefile.am: remove include_HEADERS (was libguile.h)
3796         libguile.h: moved to top level directory.
3797
3798 2000-04-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3799
3800         * numbers.c (SCM_SWAP):  Moved to the top of the file to allow for
3801         a wider use.
3802
3803         * numbers.c (scm_modulo, scm_gcd, scm_lcm, scm_logand, scm_logior,
3804         scm_logxor):  Reordered dispatch sequence, thereby fixing some
3805         comparisons of SCM values with integer constants.
3806
3807         * number.c (scm_logtest):  Removed some redundant SCM_{N}?IMP
3808         tests.
3809
3810 2000-04-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3811
3812         * numbers.c (scm_quotient, scm_remainder):  Removed code that was
3813         conditionally compiled based on BADIVSGNS.  BADIVSGNS does not
3814         occur anywhere else throughout guile.
3815
3816         * numbers.c (scm_quotient):  Fixed parameter number in error
3817         message.
3818
3819         * numbers.c (scm_remainder):  Reordered dispatch sequence.
3820
3821 2000-04-25  Gary Houston  <ghouston@arglist.com>
3822
3823         * posix.c (scm_execlp): docstring fix (thanks to Martin
3824         Grabmueller).
3825
3826 2000-04-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3827
3828         * eval.c (undef_object):  Made into a local static variable
3829         (suggested by Jost Boekemeier).
3830
3831 2000-04-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3832
3833         * pairs.c (cxrs, scm_init_pairs):  Simplify initialization of
3834         c[ad]+r functions.
3835
3836         * procs.c (scm_init_iprocs), procs.h (scm_subr, scm_iproc,
3837         scm_dsubr, scm_init_iprocs):  Removed.
3838
3839         * procs.h (SCM_SUBRF, SCM_DSUBRF):  Access the cell words
3840         directly instead of casting a cell to a C struct.
3841
3842 2000-04-22  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
3843
3844         Better modularization of GC extensions through new C level GC
3845         hooks:
3846
3847         * weaks.c (scm_weaks_prehistory): New function: Add
3848         scm_weak_vector_gc_init to scm_before_mark_c_hook; Add
3849         scm_mark_weak_vector_spines to scm_before_sweep_c_hook.
3850         (scm_scan_weak_vectors): New function; added to
3851         scm_after_sweep_c_hook.
3852
3853         * weaks.h (scm_weak_vectors, scm_weaks_prehistory): Added
3854         declarations.
3855
3856         * guardians.h (scm_guardian_gc_init, scm_guardian_zombify): Are
3857         now static.
3858
3859         * guardians.c (scm_guardian_gc_init): Turned into a hook function
3860         and added to scm_before_mark_c_hook.
3861         (scm_guardian_zombify): Turned into a hook function and added to
3862         scm_before_sweep_c_hook.
3863
3864         * async.c (scm_sys_gc_async_thunk): Run after-gc-hook.
3865         Added #include "libguile/gc.h".
3866
3867         * gc.h: Added #include "libguile/hooks.h".
3868
3869         * gc.c: Removed #include "libguile/guardians.h".
3870         (scm_before_gc_c_hook, scm_before_mark_c_hook,
3871         scm_before_sweep_c_hook, scm_after_sweep_c_hook,
3872         scm_after_gc_c_hook): New C level hooks.
3873         (scm_after_gc_hook): New Scheme level hook.
3874         (scm_gc_sweep): Moved scanning of weak vectors to weaks.c.
3875         (scm_igc): Moved initialization of scm_weak_vectors and the call
3876         to scm_guardian_gc_init to respective module.
3877         (scm_mark_weak_vector_spines): Moved to weaks.c;
3878         Call to scm_guardian_zombify moved to guardians.c;
3879         Run scm_before_gc_c_hook, scm_before_sweep_c_hook,
3880         scm_after_gc_c_hook at appropriate places.
3881         (scm_init_gc): Initialize scm_after_gc_hook.
3882
3883         * hooks.c, hooks.h (scm_make_hook_with_name): Removed deprecated
3884         function.
3885
3886         * init.c (scm_boot_guile_1): Added `scm_init_hooks'.
3887
3888         * Makefile.am: Added hooks.c, hooks.h, hooks.x.
3889
3890         * feature.c, feature.h: Broke out hook code into separate files.
3891
3892         * hooks.c, hooks.h: New files.
3893
3894         * *.*: Change includes so that they always use the "prefixes"
3895         libguile/, qt/, guile-readline/, or libltdl/.
3896         (Thanks to Tim Mooney.)
3897
3898         * Makefile.am (INCLUDES): Removed THREAD_CPPFLAGS and INCLTDL.
3899         (DEFS): Added.  automake adds -I options to DEFS, and we don't
3900         want that.
3901         Removed all -I options except for the root source directory and
3902         the root build directory.
3903
3904         * numbers.c (scm_odd_p, scm_even_p): Use SCM_WRONG_TYPE_ARG
3905         instead of SCM_ASSERT (0, ...).  (Some compilers will complain
3906         about control reaching end of function otherwise, and, besides,
3907         the new code is not less clear.)
3908
3909         * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Added
3910         calls to malloc debugging functions.
3911
3912         * init.c (scm_boot_guile_1): Added calls to debug-malloc init
3913         functions.
3914
3915         * Makefile.am: Added debug-malloc.c, debug-malloc.h,
3916         debug-malloc.x.
3917
3918         * debug-malloc.c, debug-malloc.h: New files.
3919
3920 2000-04-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3921
3922         * numbers.c (scm_exact_p, scm_odd_p, scm_even_p):  Added
3923         documentation strings.
3924
3925         * numbers.c (scm_exact_p, scm_odd_p, scm_even_p, scm_abs,
3926         scm_quotient):  Reordered dispatch sequence to first handle
3927         immediates, second handle bignums and finally handle generic
3928         functions respectively signal wrong type arguments.  Hopefully
3929         this will allow for easier separation when goops is integrated.
3930
3931 2000-04-19  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3932
3933         * gc.c (which_seg):  Use SCM2PTR to convert a non immediate SCM
3934         variable into a pointer to a heap cell.
3935
3936         * gc.c (scm_mark_locations, scm_cellp, init_heap_seg,
3937         scm_unhash_name):  Remove redundant cast to SCM_CELLPTR.
3938
3939 2000-04-19  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3940
3941         * print.c (scm_iprin1):  Don't assign zero to SCM values, use
3942         SCM_UNDEFINED instead.
3943
3944         * weaks.c (scm_make_weak_vector):  Fix assignment of zero to a
3945         vector element.  (Still to be improved)
3946
3947 2000-04-19  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3948
3949         * eval.c (undef_cell):  Removed, replaced by:
3950
3951         (undef_object):  Added to replace undef_cell.
3952
3953         (scm_lookupcar, scm_lookupcar1):  Use undef_object.
3954
3955         * eval.c (scm_lookupcar, scm_lookupcar1, scm_m_atfop,
3956         scm_m_atbind, CHECK_EQVISH, SCM_CEVAL), procs.h (SCM_SETCODE):
3957         Don't perform arithmetic operations with SCM values.
3958
3959         * eval.c (scm_lookupcar, scm_lookupcar1, scm_m_atfop,
3960         scm_m_atbind, scm_eval_args, scm_deval_args, SCM_CEVAL):  Use
3961         symbolic names for the tc3 type codes.
3962
3963         * eval.c (scm_m_define, SCM_CEVAL, SCM_APPLY):  Remove redundant
3964         cast to SCM.
3965
3966         * eval.c (scm_eval_args, scm_deval_args, SCM_CEVAL):  Made the
3967         access of the struct vcell element explicit.
3968
3969 2000-04-19  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
3970
3971         * struct.c (scm_struct_free_light, scm_struct_free_standard,
3972         scm_struct_free_entity): Use `scm_must_free' instead of `free'.
3973
3974         * procs.c (scm_make_subr_opt): Tell scm_must_realloc that we're
3975         realloc:ing scm_subr_table ("what" instead of "who").
3976
3977         * numbers.c (scm_adjbig): Ditto.
3978
3979 Tue Apr 18 08:22:41 2000  Greg J. Badros  <gjb@cs.washington.edu>
3980
3981         * validate.h: Do not cast to (unsigned) in SCM_VALIDATE_INUM_RANGE
3982         when testing high-end of the range.  Mikael Djurfeldt noticed this
3983         anomaly -- thanks Mikael!
3984
3985 2000-04-18  Dirk Herrmann  <D.Herrmann@tu-bs.de>
3986
3987         * unif.c (l2ra):  Don't eliminate the call to scm_array_set_x
3988         itself, as was done in the previous 'patch'.  (Thanks to Radey
3989         Shouman)

4167
4168         * numbers.c (scm_quotient, scm_modulo):  Reordered to handle the

4209
4210         * async.[ch]: unexpose low-level async access macros (thanks to
4211         Dirk Herrmann).

4214         needs them anyway), and rename them.
4215
4216 2000-04-04  Michael Livshin  <mlivshin@bigfoot.com>
4217
4218         * async.h: kill the scm_async_t struct.  having a heap cell
4219         pretending to be a C struct is not helthy, and is not needed here
4220         anyway, as asyncs happily fit in one heap cell.
4221
4222         * async.c: reflect the fact that asyncs are now represented by

4290         separate loop after processing all the currently known live
4291         guardians, so as to not introduce order dependencies (thanks to
4292         Gary Houston).  note that the order problems are still there if
4293         some guardians are themselves zombies, but that's a sick case that
4294         I'm not going to worry about.
4295         also, make another outer loop to process zombified
4296         guardians (which are uncovered while marking zombies).

4385         empty tconc pair to SCM_EOL instead of SCM_BOOL_F, avoiding the
4386         use of an improper list (which breaks g_print.  g_print isn't
4387         used).
4388         guardians.c: Added more comments and modified the make-guardian
4389         docstring.  Reordered a few procedures.

4436
4437         * coop-defs.h (struct coop_t): Added `sto'-field again because of
4438         binary compatibility---let's remove it next time we alter some
4439         major structure.
4440
4441         * coop.c (coop_quitting_p, coop_cond_create, coop_mutex_create,

4444         (coop_create): New thread spawning mechanism which uses a "mother

4446         to new threads since Linux threads thinks they are asleep.
4447
4448         * coop-defs.h (struct coop_t): Removed dummy_mutex.
4449
4450         * coop-defs.h, coop-threads.c (struct coop_t): Eliminate

4458
4459         * arbiters.c (SCM_ARB_LOCKED, SCM_LOCK_ARB, SCM_UNLOCK_ARB):
4460         Access the locking information in cell entry 0 with
4461         SCM_{SET_}?CELL_WORD_0 instead of SCM_*CAR.
4462
4463         * async.c (scm_run_asyncs):  Use SCM_NULLP to test for the empty

4476         Don't use C operators == and != to compare SCM values, use
4477         SCM_EQ_P instead.
4478
4479         * boolean.c (scm_boolean_p):  Use SCM_BOOLP to determine whether a
4480         SCM value is equal to #t or #f.
4481
4482         * eq.c (scm_eqv_p, scm_equal_p):  Don't use SCM_CAR to access the
4483         cell type entry of non immediate objects of unknown type.  Use

4507         data, use SCM_{SET_}?CELL_TYPE or SCM_{SET_}?WORD_[1-3].
4508

4510         values of type scm_bits_t.
4511
4512 2000-03-29  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
4513
4514         * threads.c (scm_init_threads): Pass 0 size to scm_make_smob_type
4515         for scm_tc16_thread.  As the current COOP threads are written, GC
4516         is not supposed to manage storage for threads.
4517
4518         * error.c (scm_error): Don't try to throw an error if
4519         scm_gc_heap_lock is true.
4520
4521         * coop.c (coop_finish): New function.  Called at exit.
4522         (coop_aborthelp): Free thread structures when threads die.
4523         Finished LinuxThreads compatibility support => COOP threads now
4524         mesh with LinuxThreads.
4525
4526         * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread):
4527         Changed SETCDR --> SET_CELL_WORD_1.

4544         (SCM_SETJMPBUF):  Deprecated.  Use SCM_SET_CONTREGS instead.
4545
4546         (SCM_JMPBUF, SCM_DYNENV, SCM_THROW_VALUE, SCM_BASE, SCM_SEQ,
4547         SCM_DFRAME):  Use SCM_CONTREGS instead of SCM_CHARS to access
4548         continuation data.
4549
4550         * continuations.c (scm_make_cont), init.c (start_stack),
4551         root.c (scm_internal_cwdr):  Use SCM_SET_CONTREGS instead of
4552         SCM_SETJMPBUF.
4553
4554 2000-03-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>
4555
4556         * symbols.h (SCM_LENGTH, SCM_SETLENGTH):  Access the length field
4557         of strings and symbols by using SCM_{SET_}?CELL_WORD_0.
4558
4559         (SCM_CHARS, SCM_UCHARS, SCM_SETCHARS):  Use SCM_{SET_}?CELL_WORD_1
4560         to access the char * field of strings and symbols.
4561
4562 2000-03-27  Dirk Herrmann  <D.Herrmann@tu-bs.de>
4563
4564         * gc.h (SCM_NEWCELL, SCM_NEWCELL2):  Use SCM_SET_CELL_TYPE to set
4565         the type entry of a new cell.  Added a comment about things to
4566         remember when updating the list of free cells.
4567
4568         (SCM_FREEP, SCM_MARKEDP):  Use SCM_CELL_TYPE to access the type
4569         entry of a cell.
4570
4571 2000-03-27  Dirk Herrmann  <D.Herrmann@tu-bs.de>
4572
4573         * pairs.h (SCM_CAR, SCM_CDR, SCM_SETCAR, SCM_SETCDR):  Use
4574         SCM_CELL_OBJECT and SCM_SET_CELL_OBJECT.  This change implies that
4575         with strict type checking enabled these macros will only work if
4576         given valid SCM parameters.
4577
4578         (SCM_GCCDR):  Moved to tags.h.
4579
4580         * tags.h (SCM_GCCDR):  Moved here from pairs.h.

4593         SCM_SETOR_CAR, SCM_SETOR_CDR):  Moved to gc.h.  These names should
4594         be changed, though, since the macros are not only pair related.
4595
4596         (SCMPTR):  Deleted.
4597
4598         * gc.h (SCM2PTR, PTR2SCM, scm_cell, SCM_CELLPTR, SCM_CELL_WORD*,
4599         SCM_CELL_OBJECT*, SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*,

4603         SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR):  Moved here from
4604         tags.h and pairs.h.
4605
4606 2000-03-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>
4607
4608         * tags.h (SCM_STRICT_TYPING):  New macro that, if defined,
4609         activates strict compile time type checking for variables of
4610         type SCM.
4611         (SCM, SCM_PACK, SCM_UNPACK):  Define according to whether
4612         SCM_STRICT_TYPING or SCM_VOIDP_TEST are defined.
4613         (SCM_EQ_P):  Defined as a macro equivalent for eq?.
4614
4615 2000-03-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>
4616
4617         * tags.h (SCM_POINTERS_MUNGED):  Removed.
4618
4619         * gc.c (scm_gc_sweep, init_heap_seg):  Removed use of
4620         SCM_POINTERS_MUNGED, thus fixing some illegal casts to SCM.
4621
4622 2000-03-24  Dirk Herrmann  <D.Herrmann@tu-bs.de>
4623
4624         * pairs.h (SCM_CELL_OBJECT, SCM_CELL_OBJECT_[0-3],
4625         SCM_SET_CELL_OBJECT, SCM_SET_CELL_OBJECT_[0-3], SCM_CELL_TYPE,
4626         SCM_SET_CELL_TYPE):  Added a set of low level macros for accessing
4627         cell entries.
4628         (SCM_CELL_WORD_[0-3]): Renamed from the SCM_CELL_WORD[0-3].
4629
4630         * procs.h, procs.c:  Instead of SCM_{SET_}?CELL_WORD[12], use the
4631         newly introduced SCM_{SET_}?CELL_OBJECT_[12] macros.
4632
4633 2000-03-23  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
4634
4635         * tags.h: Disabled definition of SCM_VOIDP_TEST.
4636
4637         Defining SCM as void * introduces problems which haven't been
4638         handled yet.  Developers who work with these issues can enable it
4639         in their working copies.

4641         Disabling this definition exposes a set of newly introduced and
4642         older misuses of types which causes warning messages during
4643         compilation.  We'll fix this successively.
4644
4645         * gc.c (scm_mark_locations): Changed * (SCM **) X --> * (SCM *) X
4646         in order to obtain a value of type SCM.
4647         (scm_cellp): Updated with new changes to scm_mark_locations.
4648
4649         * continuations.h (SCM_SETJMPBUF): Cast second arg into SCM.
4650
4651         * continuations.c (scm_make_cont): Removed cast of size_t into
4652         long.
4653
4654         * symbols.h (SCM_SETCHARS): Cast second arg into SCM.
4655
4656 2000-03-22  Dirk Herrmann  <D.Herrmann@tu-bs.de>
4657
4658         * numbers.h (SCM_SETNUMDIGS):  Use SCM_BIGSIZEFIELD macro for
4659         shifting, not constant.  Thanks to Dale P. Smith.
4660
4661         * numbers.c (scm_sum, scm_difference):  Don't test a SCM value
4662         for being less than zero.  Decode it to a C value first.  Again,
4663         thank you Dale.
4664
4665 2000-03-22  Dirk Herrmann  <D.Herrmann@tu-bs.de>
4666
4667         * numbers.h, ramap.c, struct.h, vectors.h:  Don't use SCM2PTR for
4668         non scheme values.  If raw data is stored in SCM variables, it has
4669         to be accessed using SCM_UNPACK until a better solution is found.
4670
4671 2000-03-22  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
4672
4673         * tags.h (SCM_ECONSP, SCM_NECONSP): More corrections of
4674         pointer-arithmetic induced by the SCM_PACK/UNPACK change.
4675
4676         * print.c (scm_iprin1): SCM_PACK/UNPACK corrections.
4677
4678         * gc.c (scm_gc_sweep): SCM_PACK/UNPACK corrections.
4679
4680         * eval.c (SCM_CEVAL, scm_unmemocar): SCM_PACK/UNPACK corrections.
4681
4682         * dynwind.c (scm_swap_bindings): SCM_PACK/UNPACK corrections.
4683
4684         * async.c, __scm.h: Removed lots of the old async click logic.  It
4685         is possible to reinsert it by defining GUILE_OLD_ASYNC_CLICK in
4686         __scm.h.  Let's try this out and dump the old code after the
4687         threads reorganization.
4688         (set-tick-rate, set-switch-rate): Conditionally removed.
4689
4690 2000-03-21  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
4691
4692         * gc.c (scm_gc_mark): Bugfix 1: The recent SCM_PACK/UNPACK change
4693         made SCM values into pointers.  This turned an arithmetic
4694         computation of the address of the vcell into a pointer-arithmetic
4695         one, thereby screwing up marking of structs.
4696         Bugfix 2: Removed incompletely introduced loop variable `j' used
4697         when protecting the tail array of a struct.
4698
4699 2000-03-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>
4700
4701         * struct.h (SCM_STRUCT_DATA):  Don't cast SCM values to pointers.
4702
4703 2000-03-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>
4704
4705         * symbols.h, symbols.c (scm_strhash):  Declare the string
4706         parameter as constant, since it is not modified.
4707
4708         * symbols.c (scm_intern_obarray_soft,
4709         scm_sysintern0_no_module_lookup):  Can now pass constant strings
4710         to scm_strhash without need for casting.
4711
4712 2000-03-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>
4713
4714         * vectors.h (SCM_VELTS, SCM_VELTS_AS_STACKITEMS):  Don't cast SCM
4715         values to pointers.  Use SCM2PTR instead.
4716
4717 2000-03-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>
4718
4719         * async.c (scm_set_tick_rate, scm_set_switch_rate):  Don't unpack
4720         results of SCM_INUM.
4721
4722 2000-03-21  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
4723
4724         * init.c (scm_boot_guile_1): Renamed GUILE_GC_TRIGGER_1 -->
4725         GUILE_MIN_YIELD_1, GUILE_GC_TRIGGER_2 --> GUILE_MIN_YIELD_2.
4726         GUILE_MIN_YIELD_X now take *positive* fractions of heap size.
4727
4728         * gc.c, gc.h (SCM_MIN_YIELD_1, SCM_MIN_YIELD_2,
4729         min_yield_fraction, min_yield, adjust_min_yield): Renamed from
4730         SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2, gc_trigger_fraction,
4731         gc_trigger, adjust_gc_trigger.
4732
4733         * gc.c (alloc_some_heap): Further improvement of minimal heap size
4734         prediction.
4735         (SCM_MAX): New macro.
4736         (scm_freelist_t): New field: collected_1. Previous amount of
4737         collected cells.
4738         (gc_sweep_freelist_finish): Trigger based on two last values of
4739         freelist->collected to avoid unnecessary allocation due to
4740         temporary peaks.
4741         (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2):
4742         Adjusted to 45000 cells, 40% and 40%.  Gives quick startup
4743         without extra heap allocation.
4744
4745 2000-03-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>
4746
4747         * numbers.h (SCM_MAKINUM):  The parameter to SCM_MAKINUM should
4748         already be a C value.  No need to unpack it.
4749
4750         * numbers.c (scm_long_long2num):  Cast the parameter to scm_bits_t
4751         if we know it fits into an inum.
4752
4753         * ramap.c (ramap_rp):  An scm_tc7_[ui]vect object does point to a
4754         field of long values.  In contrast, SCM_VELTS accesses a field of
4755         SCM values.
4756
4757 2000-03-20  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
4758
4759         * gc.c (scm_gc_stats): Inserted explanation of local_scm_mtrigger
4760         etc.
4761         (scm_gc_yield_1): New variable: Holds previous yield.  Used to
4762         make better judgements.
4763         (gc_sweep_freelist_finish): Inserted explanation of use of
4764         gc_trigger.
4765
4766         * print.h, stacks.h, options.c, options.h: Changed C++
4767         commentaries to C.
4768
4769 2000-03-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>
4770
4771         * tags.h (SCM2PTR, PTR2SCM):  Use SCM_PACK / SCM_UNPACK correctly.
4772
4773         * numbers.h (SCM_INUMP, SCM_MAKINUM, SCM_INUM0, SCM_COMPLEX_REAL,
4774         SCM_COMPLEX_IMAG, SCM_NUMP, SCM_BDIGITS):  Use SCM_PACK /
4775         SCM_UNPACK / SCM2PTR correctly.
4776
4777 2000-03-20  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
4778
4779         * gc.c (adjust_gc_trigger): Improved documentation.
4780         (alloc_some_heap): Since gc_trigger is used against
4781         freelist->collected, this is the value which should be used to
4782         predict minimum growth.
4783
4784 2000-03-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>
4785
4786         * eval.h:  Fix mixup of packed/unpacked SCM values.  (Thanks
4787         Thien-Thi Nguyen for the patch.)
4788
4789 2000-03-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>
4790
4791         * numbers.c (scm_ash):  Fixed typing problems with the second
4792         parameter and added some documentation.  (Thanks Thien-Thi Nguyen
4793         for indicating the problem.)
4794
4795 2000-03-19  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
4796
4797         * gc.c, gc.h (scm_gc_yield): New variable.
4798         (adjust_gc_trigger): Use scm_gc_yield.
4799         (alloc_some_heap): Use scm_gc_yield instead of
4800         scm_gc_cells_collected.
4801
4802         * coop-threads.c: Addd #include "root.h", #include "strings.h".
4803
4804         * debug.c: Added #include "root.h".  (Thanks to Thien-Thi Nguyen.)
4805
4806         * gc.c (scm_gc_for_newcell, adjust_gc_trigger): Improved GC
4807         trigger adjustmeant: Take yield (freed cells) for all freelists
4808         into account.
4809         (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Tuned
4810         to 50000 cell heap with 45% trigger.
4811         (scm_gc_cells_collected): Reintroduced.
4812         (SCM_HEAP_SIZE): New macro.
4813         (scm_gc_sweep): Reintroduced correct computation of
4814         scm_cells_allocated.
4815         (scm_freelist_t): Corrected commentary for field `cluster_size':
4816         Clustersize counts objects, not cells;  New member
4817         `clusters_allocated'.
4818
4819 2000-03-19  Michael Livshin  <mlivshin@bigfoot.com>
4820
4821         * *.[hc]: add Emacs magic at the end of file, to ensure GNU
4822         indentation style.
4823
4824 2000-03-19  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
4825
4826         * threads.h: Added #include "libguile/throw.h".  (Thanks to
4827         Thien-Thi Nguyen.)
4828
4829 2000-03-18  Michael Livshin  <mlivshin@bigfoot.com>
4830
4831         * tags.h: (SCM_DOUBLE_CELLP, SCM_NDOUBLE_CELLP): new macros (bad
4832         names, anyone got any better ones?)
4833
4834         * gc.h: (typedef struct scm_freelist_t) remove from here.
4835
4836         * gc.c: (CELL_UP, CELL_DN) made these macros take additional
4837         parameter (the span).
4838         (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK) new macros.
4839         (typedef struct scm_freelist_t) moved here from gc.h, it had no
4840         business being externally visible.
4841         (typedef struct scm_heap_seg_data_t) renamed from
4842         scm_heap_seg_data, to be style-compliant.
4843         (scm_mark_locations) if the possible pointer points to a
4844         double-cell, check that it's properly aligned.
4845         (init_heap_seg) align double-cells properly, work with the
4846         assumption that the segment size divides cleanly by cluster size.
4847         (round_to_cluster_size) new function.
4848         (alloc_some_heap, make_initial_segment) use round_to_cluster_size
4849         to satisfy the new init_heap_seg invariant.

4908 2000-03-17  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
4909
4910         * gc.c, gc.h: Cleanup of the change of 2000-03-15.
4911         Cluster sizes are now independent of GC trigger values.
4912         GUILE_GC_TRIGGER_n can now specify a relative trigger value:
4913         A negative integer gives fraction of total heap size in percent.
4914         (SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Default values set to -40.
4915
4916         * init.c (scm_boot_guile_1): Introduced new variable
4917         GUILE_MAX_SEGMENT_SIZE; New environment variable names:
4918         GUILE_INIT_SEGMENT_SIZE_1, GUILE_GC_TRIGGER_1,
4919         GUILE_INIT_SEGMENT_SIZE_2, GUILE_GC_TRIGGER_2
4920
4921 2000-03-16  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
4922
4923         * __scm.h (GC_FREE_SEGMENTS): Disable this until we have made
4924         freeing of segment work with the new GC scheme.  (Thanks to
4925         Michael Livshin.)  Oops, also happened to make GUILE_NEW_GC_SCHEME
4926         the default, but I'll let this change stay in CVS Guile since this
4927         code is not expected to contain serious bugs.
4928
4929 2000-03-16  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
4930
4931         * gc.c, gc.h (scm_map_free_list): Define also if GUILE_DEBUG is
4932         defined.
4933         (scm_free_list_length): New procedure (GUILE_DEBUG).
4934         Fixed a small but serious bug introduced by the previous change.
4935
4936         * gc.c (scm_gc_sweep): Moved variable n_objects to inner sweep
4937         loop and declare as register.
4938
4939         * gc.c (scm_gc_sweep): Sigh... forgot to clear private freelists
4940         after GC.
4941
4942 Wed Mar 15 08:27:04 2000  Greg J. Badros  <gjb@cs.washington.edu>
4943
4944         * fluids.c: Docstring patch from Keisuke Nishida.  Some
4945         reindentation, too, and a couple formals renamed.  Should
4946         fluid-set! return UNSPECIFIED instead of a value?
4947
4948 Wed Mar 15 08:24:58 2000  Greg J. Badros  <gjb@cs.washington.edu>
4949
4950         * Makefile.am: Separate out DOT_X_FILES and DOT_DOC_FILES, and
4951         generate the latter from the concrete listing of the former.  Then
4952         make guile-procedures.txt depend on DOT_DOC_FILES instead of
4953         *.doc, so that rebuilding it works.
4954
4955 Wed Mar 15 08:12:14 2000  Greg J. Badros  <gjb@cs.washington.edu>
4956
4957         * libguile.h: Include libguile/validate.h.  Thanks Keisuke Nishida!
4958
4959         * guile-snarf.awk.in: Replace docstring line-ending \n" and \n\n"
4960         with nothing and \n, respectively. Thanks Keisuke Nishida for
4961         noticing this problem.
4962
4963 2000-03-15  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
4964
4965         * __scm.h (GUILE_NEW_GC_SCHEME): Define this if you want to test a
4966         new way of allocating heap.  It makes Guile fast, but still
4967         contains bugs.
4968
4969         * gc.c, gc.h, pairs.h, init.c: Implementation of a new way of
4970         allocating heap.  The basic idea is to trigger GC every Nth
4971         allocated cell and grow heap when free list runs out.  The scheme
4972         has been extended so that GC isn't triggered until all remaining
4973         cells are used.  The implementation is also prepared for
4974         development in the direction of POSIX threads.
4975
4976         * gc.c (SCM_EXPHEAP): In order to grow by a factor of 1.5,
4977         SCM_EXPHEAP should return half of the heap size.
4978
4979 2000-03-14  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
4980
4981         The following change to init.c is only enabled if Guile was
4982         configured with --enable-guile-debug.
4983
4984         * init.c (scm_i_getenv_int): New function.
4985         (scm_boot_guile_1): Use the environment variables
4986         GUILE_INIT_HEAP_SIZE, GUILE_INIT_HEAP_SIZE2 to select heap size if
4987         they exist.  (This may be replaced by a Scheme level mechanism in
4988         the future.)
4989
4990         * objprop.c (s_scm_set_object_property_x): Use scm_assq instead of
4991         scm_assoc.  (Thanks to Keisuke Nishida.)
4992
4993 2000-03-14  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
4994
4995         * eval.c, lang.c, lang.h (scm_lisp_nil, scm_lisp_t): Renamed from
4996         scm_nil, scm_t.  (Thanks to Keisuke Nishida.)
4997
4998 2000-03-14  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
4999
5000         * init.c (scm_boot_guile_1): Use same initial segment size for
5001         1-word and 2-word segments.  Having the smaller size causes Guile
5002         to GC too often.  Obviously something needs to be done to allow
5003         for a smaller 2-word segment without this to happen.  (The amount
5004         of heap for each type should be automatically adapted to the
5005         application somehow.)
5006
5007         [Almost all of these changes should be documented in the NEWS
5008         file.]
5009
5010         * gc.h (scm_freelist_t): New type.
5011
5012         * pairs.h (SCM_NEWCELL, SCM_NEWCELL2): Use new style freelists.
5013
5014         * gc.c (SCM_INIT_HEAP_SIZE): Changed from 32768 --> 40000 so that
5015         all of Guile basics fits into one segment and there suitable room
5016         for work.
5017         (SCM_EXPHEAP): Now takes an argument.  Grow by a factor of 1.5
5018         instead of 2.
5019         (scm_freelist, scm_freelist2): Now of type scm_freelist_t.
5020         Freelists now contains information about object span, cells
5021         collected and amount of cells in heap segments belonging to the
5022         list.
5023         (scm_heap_size, scm_gc_cells_collected): Removed.
5024
5025         * init.c (scm_boot_guile_1): Make 2-word segment 8K (512 cells).
5026
5027         * Makefile.am (libguile_la_LDFLAGS): Bumped library version
5028         number.
5029
5030         * __scm.h eq.c, eval.c, gc.c, gc.h, gh_data, hash.c, numbers.c,
5031         numbers.h, objects.c, ramap.c, random.c, unif.c, unif.h: Extensive
5032         rewrite of handling of real and complex numbers.
5033         (SCM_FLOATS, SCM_SINGLES): These #ifdef conditionals have been
5034         removed along with the support for floats.  (Float vectors are
5035         still supported.)
5036
5037         * tags.h (scm_tcs_bignums): Removed.
5038         (scm_tc16_bigpos, scm_tc16_bigneg): Replaced by scm_tc16_big.
5039         Use SCM_BIGSIGN(x) to test for sign!
5040         (scm_tc16_big): The new bignum type.
5041         (SCM_REAL_PART, SCM_IMAG_PART): Removed.
5042
5043         * numbers.h (SCM_BIGSIGN): Sign moved to bit 16.
5044         (scm_makdbl): Deprecated.
5045         (SCM_NEWREAL, SCM_NEWCOMPLEX): New macros.
5046         (SCM_SINGP): Deprecated.
5047         (SCM_FLO): Removed.
5048         (SCM_INEXP, SCM_CPLXP): Deprecated.
5049         (SCM_INEXACTP, SCM_COMPLEXP): New macros.
5050         (SCM_COMPLEX_REAL, SCM_COMPLEX_IMAG): Renamed from
5051         SCM_REAL, SCM_IMAG (and now only valid for complex numbers).
5052         (SCM_REAL, SCM_IMAG): New, *deprecated*, selectors which work both
5053         for doubles and complex numbers.
5054         (SCM_REAL_VALUE): New selector for doubles.
5055         (scm_double_t, scm_complex_t): New types.
5056         (scm_dbl): Removed.
5057
5058         * numbers.c (scm_floprint, scm_floequal): Removed.
5059         (scm_print_real, scm_print_complex, scm_real_equalp,
5060         scm_complex_equalp): New functions.
5061
5062         * unif.c (scm_makflo): Removed.
5063
5064         * smob.h (SCM_SMOB_PREDICATE): New macro.
5065         (SCM_NEWSMOB2, SCM_RETURN_NEWSMOB2, SCM_NEWSMOB3,
5066         SCM_RETURN_NEWSMOB3): New macros.
5067
5068 1999-11-21  Michael Livshin  <mlivshin@bigfoot.com>
5069
5070         The following changes implement primitive support for double cells
5071         (i.e. four-word cells) and change the representation of some
5072         things to multi-cells instead of cons+malloc.  (Applied and
5073         modified by mdj.)
5074
5075         * pairs.h (SCM_NEWCELL2): double-cell variants of SCM_NEWCELL.
5076         (SCM_CELL_WORD, SCM_CELL_WORDLOC, SCM_SET_CELL_WORD): primitive
5077         multi-cell access macros (used by the ones below).
5078         (SCM_CELL_WORD[0-3], SCM_SET_CELL_WORD[0-3]): multi-cell access
5079         macros.
5080
5081         * gc.c (scm_freelist2): multi-cell freelists.
5082         (inner_map_free_list): map_free_list, parameterized on ncells.
5083         "nn cells in segment mm" was misleading for ncells > 1; changed to
5084         "objects".  still print cells too, though.
5085         (scm_map_free_list): rewritten using inner_map_free_list.
5086         (scm_check_freelist): get freelist as parameter, since now we have
5087         more than one.
5088         (scm_debug_newcell2): multi-cell variants of
5089         scm_debug_newcell.
5090         (scm_gc_for_newcell): take ncells and freelist pointer as
5091         parameters.
5092         (scm_gc_mark): add case for tc7_pws (procedures with setters are
5093         now double cells).
5094         (scm_gc_sweep): don't free the float data, since it's not malloced
5095         anymore.
5096         (init_heap_seg): didn't understand what n_new_objects stood for,
5097         so changed to n_new_cells.
5098         (make_initial_segment): new function, makes an initial segment
5099         according to given ncells.
5100         (scm_init_storage): call make_initial_segment, for ncells={1,2,3}.
5101
5102         * numbers.c (scm_makdbl): no malloc'ing needed, so the
5103         {DEFER,ALLOW}_INTS thing removed.
5104
5105         * numbers.h (struct scm_dbl): changed to represent a double cell,
5106         with the number in the second half.
5107
5108         * dynwind.c: changed the wind-guards representation to double
5109         cell.
5110
5111         * procs.c, procs.h: changed the procedure-with-setter representation
5112         to double cell.
5113
5114         * async.c, async.h: made async representation a double cell.
5115
5116         * dynl.c: made dynamic_obj representation a double cell.
5117
5118 2000-03-13  Gary Houston  <ghouston@arglist.com>
5119
5120         * ports.c (flush_void_port): renamed to flush_port_default.
5121         (end_input_void_port): renamed to end_input_default.
5122
5123         * init.c (scm_standard_stream_to_port): create a void port instead
5124         of opening /dev/null if the standard file descriptors are bad.
5125         advantages: no portability problems, doesn't waste a file descriptor,
5126         simplifies the code (thanks to Marius for the idea).
5127
5128         * vports.c (s_scm_make_soft_port): call scm_port_non_buffer.
5129
5130         * void ports: make reading from a void port give EOF instead of
5131         segv:
5132         * ports.c (s_scm_sys_make_void_port): modified docstring.
5133         (fill_input_void_port): new proc.
5134         (scm_init_ports): set up fill_input_void_port.
5135         * ports.c (scm_port_non_buffer): new proc.
5136         (scm_void_port): call scm_port_non_buffer.
5137
5138         * fports.c (scm_setvbuf): docstring: remove the fcntl documentation
5139         which was incorrectly appended.
5140
5141 2000-03-13  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
5142
5143         * guile-doc-snarf.in: Don't use absolute path for `sed'.  (Note
5144         that we can't use autoconf for this.  Autoconf itself relies on
5145         the existence of `sed' somewhere on your path.)  (Thanks to Dirk
5146         Herrman.)
5147
5148 2000-03-13  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
5149
5150         * Makefile.am (libguile_la_SOURCES): Moved iselect.c here from
5151         EXTRA_libguile_la_SOURCES.
5152
5153         * iselect.h: Always declare scm_internal_select.
5154
5155         * iselect.c (scm_internal_select): Added SCM_ASYNC_TICK at the
5156         end.  Also let scm_internal_select be a real function also when
5157         not using threads.
5158
5159         * __scm.h (SCM_TICK): Oops! Forgot to put SCM_ASYNC_TICK here...
5160
5161 2000-03-13  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
5162
5163         * __scm.h (SCM_ALLOW_INTS, SCM_REALLOW_INTS): Removed call to
5164         SCM_ASYNC_TICK.  (This is a preparation for POSIX threads support,
5165         and kind of an experiment: Will this cause problems?)
5166
5167 Sun Mar 12 13:26:30 2000  Greg J. Badros  <gjb@cs.washington.edu>
5168
5169         * Makefile.am: Added *.doc to DISTCLEANFILES.
5170
5171 2000-03-12  Gary Houston  <ghouston@arglist.com>
5172
5173         * fports.c (scm_fdes_to_port): call fcntl F_GETFL to test that
5174         the fdes is valid before doing anything else.  check that
5175         the file descriptor supports the modes required.
5176         (scm_fport_buffer_add): don't throw an error if fstat doesn't
5177         work: just use the default buffer size.
5178
5179         * throw.c: change an outdated comment about scm_internal_catch
5180         BODY: it doesn't take a jumpbuf arg.
5181
5182         * init.c (scm_standard_stream_to_port): install a handler in case
5183         scm_fdes_to_port throws an error.  don't check here whether the
5184         file descriptor is valid, since scm_fdes_to_port will do that.
5185         set the revealed count depending on whether the port got the
5186         standard file descriptor.
5187         (stream_body_data): new type.
5188         (stream_body, stream_handler): new procs.
5189
5190 2000-03-12  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
5191
5192         * stacks.c, stacks.h, struct.c, tags.h, unif.c (scm_bits_t):
5193         Renamed from SCMWORD.
5194
5195         * tags.h (SCM_NCELLP): Removed (SCMWORD).
5196
5197         * arbiters.c (SCM_ARB_LOCKED): Use SCM_UNPACK_CAR.
5198
5199         * async.c, boolean.h, debug.c, dynl.c, dynwind.c, eval.c, eval.h,
5200           feature.h, filesys.h, fluids.h, fports.c, fports.h, gc.c, gc.h,
5201           hash.c, keywords.h, macros.c, numbers.c, numbers.h, objects.c,
5202           objects.h, options.c, pairs.h, ports.c, ports.h, print.c,
5203           procs.h, ramap.c, read.c, smob.c, smob.h, srcprop.h, stacks.c,
5204           stacks.h, strports.c, struct.c, struct.h, tag.c, tags.h,
5205           throw.c, unif.c, unif.h, variable.h, vectors.h, weaks.c,
5206           weaks.h (SCM_PACK, SCM_UNPACK, SCM_UNPACK_CAR): Renamed from
5207           SCM_ASSCM, SCM_ASWORD, SCM_CARW).
5208
5209         * numbers.h (SCM_SRS, SCM_INUM): Corrected SCM_ASSCM/ASWORD fixes.
5210
5211         * alist.c, eval.c, net_db.c, posix.c, print.c, snarf.h, struct.c,
5212         tags.h: Fixed copyright notices.
5213
5214         * struct.c, coop-threads.c: SCM_ASSCM/ASWORD fixes.
5215
5216 2000-03-12  Marius Vollmer  <mvo@zagadka.ping.de>
5217
5218         * init.c (scm_standard_stream_to_port): Check whether the file
5219         descriptor is valid and substitute "/dev/null" when not.
5220
5221 2000-03-12  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
5222
5223         * coop-defs.h (struct timespec): Conditionally defined.
5224
5225         * coop.c (coop_condition_variable_timed_wait_mutex): Use ETIMEDOUT
5226         instead of ETIME.
5227
5228         * readline.c (match_paren): Bugfix: First arg to select is not
5229         number of descriptors but the number of the highest descriptor +
5230         1.
5231
5232         This is a preliminary attempt at a cleanup of the threads support
5233         code.  It moves things to better places, makes arguments more
5234         consistent with the POSIX API (which is used in GNOME's glib), and
5235         adds new functionality.
5236
5237         * readline.c (scm_init_readline): Added new arg to scm_init_mutex.
5238
5239         * coop-defs.h (scm_mutex_trylock): New macro: alias for
5240         coop_mutex_trylock.
5241         (scm_cond_init): Changed definition to
5242         coop_new_condition_variable_init.
5243
5244         * coop.c: #include <errno.h>
5245         (coop_timeout_qinsert): Moved here from iselect.c
5246         (coop_new_mutex_init, coop_new_condition_variable_init): New
5247         functions.  The strange names are temporary.  Use scm_mutex_init
5248         and scm_cond_init instead.
5249         (coop_mutex_trylock): New function.  Uses errno.h:EBUSY.  errno.h
5250         is ANSI C, but should we check for individual error codes in
5251         configure.in?
5252         (coop_condition_variable_timed_wait_mutex): New function.
5253         (coop_key_create, coop_setspecific, coop_getspecific,
5254         coop_key_delete): New functions.
5255
5256         * iselect.c (coop_timout_qinsert): Moved to coop.c
5257
5258 2000-03-11  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
5259
5260         * pairs.h (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR,
5261         SCM_SETOR_CDR): Corrected SCM_ASSCM/WORD fixes.
5262
5263         * tags.h (SCM_VOIDP_TEST): Renamed from VOIDP_TEST.
5264         Layout cleanups.
5265
5266         * objects.h (SCM_CLASS_FLAGS, SCM_OBJ_CLASS_FLAGS,
5267         SCM_SET_CLASS_INSTANCE_SIZE), struct.h (SCM_STRUCT_VTABLE_DATA),
5268         proc.h (SCM_CLOSCAR): SCM_ASSCM/WORD fixes.
5269
5270         * eval.c (scm_lookupcar1): Inserted SCM_ASWORD in expressions
5271         dealing with ilocs.
5272
5273 2000-03-11  Dale P. Smith  <dpsm@en.com>, applied by Greg J. Badros, <gjb@cs.washington.edu>
5274
5275         * numbers.c (scm_copy_big_dec, scm_copy_smaller, scm_big_ior,
5276         scm_big_xor, scm_big_and, scm_big_test): Added new lowlevel bignum
5277         logical functions from SCM.
5278
5279         (logand, logior, logxor, logtest, logbit?): Extended scheme
5280         logical functions to use bignums from SCM.
5281
5282         (lognot): Removed call to `SCM_VALIDATE_INUM' that prevented
5283         lognot from using bignums.
5284
5285 Thu Mar  9 11:33:25 2000  Greg J. Badros  <gjb@cs.washington.edu>
5286
5287         * vectors.h (SCM_VELTS_AS_STACKITEMS): Added this macro to help in
5288         eliminating some warnings.
5289
5290         * unif.c, strports.c, print.c, options.c: Fix some warnings on
5291         mis-use of SCM/long
5292
5293         * gc.c, gc.h: Added scm_return_first_int(), and added comment re:
5294         what the scm_return_first* functions do.
5295
5296 2000-03-09  Han-Wen Nienhuys  <hanwen@cs.uu.nl>, applied by Greg J. Badros, <gjb@cs.washington.edu>
5297
5298        * libguile/*.[ch]: make a distinction between SCM as a generic
5299        name for a Scheme object (now a void*), and SCM as 32 bit word for
5300        storing tags and immediates (now a long int).  Introduced
5301        SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
5302        code in the process: arbiter.c (use macros), unif.c (scm_array_p),

5306         * numbers.c:  Use SCM_VALIDATE_LONG_COPY, and longs, not ints, in
5307         various logXXX primitives.  Thanks Eric Moore!
5308
5309 Tue Mar  7 08:05:22 2000  Greg J. Badros  <gjb@cs.washington.edu>
5310
5311         * run-test, remaining-docs-needed:  Added these scripts.  The
5312         second one is only temporary until the docstring additions are
5313         complete.   run-test may best live on, but is here mostly for
5314         convenience and awareness for now.
5315
5316         * hash.c: Docs, minor cleanup patch from Dirk Herrman.
5317
5318 Thu Mar  2 16:06:58 2000  Greg J. Badros  <gjb@cs.washington.edu>
5319
5320         * error.h, error.c: Added `scm_wrong_type_arg_msg' to support
5321         displaying the expected type.  Use SCM_LISTn in a couple places
5322         instead of scm_cons-ing by hand.
5323
5324         * __scm.h: Added SCM_ASSERT_TYPE macro.
5325
5326         * validate.h, scm_validate.h: Added the former, as a renamed
5327         version of the latter with SCM_ASSERT_TYPE used in
5328         SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
5329
5330         * Makefile.am: Rename scm_validate.h to validate.h.
5331
5332         * *.c, *.h: Include validate.h, not scm_validate.h (old name's
5333         prefix was superfluous).
5334
5335 Thu Mar  2 15:33:12 2000  Greg J. Badros  <gjb@cs.washington.edu>
5336
5337         * hashtab.c: Improved documentation for lots of functions.  Added
5338         handwritten docs for `hash-fold'.
5339
5340 Thu Mar  2 15:13:25 2000  Greg J. Badros  <gjb@cs.washington.edu>
5341
5342         * list.c: Added hand-written docs for `del{q,v,ete}1!'.
5343
5344 Thu Mar  2 12:38:30 2000  Greg J. Badros  <gjb@cs.washington.edu>
5345
5346         * list.c: Moved append docs to append! Thanks Dirk Hermann.  Also,
5347         added append docs from R4RS.
5348
5349         * strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
5350         Thanks Dirk Hermann!
5351
5352         * chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
5353         deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR.  Thanks Dirk Hermann!
5354
5355         * *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
5356         Drop use of SCM_P for function prototypes... assume an ANSI C
5357         compiler.  Thanks Dirk Hermann!
5358
5359 Sat Feb 19 12:20:12 2000  Greg J. Badros  <gjb@cs.washington.edu>
5360
5361         * ports.c: Made `set-port-column!' and `set-port-line!' each
5362         return SCM_UNSPECIFIED instead of a (not-scheme-object) integer
5363         that caused a seg fault.  Also fixed `set-port-column!'s
5364         docstring.  Thanks Han-Wen Nienhuys for finding the bug!
5365
5366 Sun Feb 13 19:11:42 2000  Greg J. Badros  <gjb@cs.washington.edu>
5367
5368         * arbiters.c, eq.c, gc.c, guardians.c, list.c, ports.c, print.c,
5369         regex-posix.c, scmsigs.c, stime.c, strings.c, variable.c, stime.c,
5370         strings.c, variable.c:  Added lots of documentation, cleaned up
5371         some existing documentation.  Occasionally changed formal params
5372         to match docs.  Also folded an #ifdef into the inners of a
5373         primitive instead of having two copies of the primitive
5374         (`get-internal-real-time', from stime.c)
5375
5376 Sun Feb 13 18:12:19 2000  Greg J. Badros  <gjb@cs.washington.edu>
5377
5378         * ports.c: Added docs for primitives missing them.  Written by
5379         hand.
5380
5381 Sun Feb 13 09:40:36 2000  Greg J. Badros  <gjb@cs.washington.edu>
5382
5383         * guile-doc-snarf.in: Use ${AWK} -f guile-func-name-check, not
5384         just execing guile-func-name-check.  Thanks Michael Livshin!
5385
5386 Thu Feb 10 11:43:23 2000  Greg J. Badros  <gjb@cs.washington.edu>
5387
5388         * guile-snarf.awk.in: Tweak to work with Sun/HP awk, removed some
5389         dead code.  Patch from Michael Livshin.
5390
5391         * guile-doc-snarf.in: Tweak to work with Sun/HP sh.  Patch from
5392         Michael Livshin.
5393
5394 2000-02-09  Gary Houston  <ghouston@arglist.com>
5395
5396         * init.c (scm_init_standard_ports): when stdout is a tty, make the
5397         current-output-port unbuffered by default.  this is less confusing
5398         for interactive use.  it was line-buffered because of a
5399         performance problem with unbuffered ports, but I think it will be
5400         OK now.
5401
5402 2000-02-08  Gary Houston  <ghouston@arglist.com>
5403
5404         * __scm.h: don't define long_long or ulong_long if HAVE_LONG_LONGS
5405         is not defined.
5406
5407         * stime.c (scm_localtime, scm_mktime): if neither HAVE_TM_ZONE nor
5408         HAVE_TZNAME are defined, use an empty string instead of giving two
5409         spurious compile-time errors.
5410
5411 Tue Feb  8 13:57:46 2000  Greg J. Badros  <gjb@cs.washington.edu>
5412
5413         * ports.c: Doc patches from Richard Kim.  Pasted from MIT Scheme.
5414         Thanks Richard!
5415
5416 Mon Feb  7 09:07:31 2000  Greg J. Badros  <gjb@cs.washington.edu>
5417
5418         * macros.c: Doc patches from Richard Kim.  Pasted from scm.texi.
5419
5420 Sun Feb  6 20:26:21 2000  Greg J. Badros  <gjb@cs.washington.edu>
5421
5422         * pairs.c: Doc patches from Richard Kim.  Pasted from MIT Scheme
5423         (which is GNU GPL'd).
5424
5425 2000-01-31  Gary Houston  <ghouston@arglist.com>
5426
5427         * strings.h: don't use SCM_P.  don't include <string.h>.
5428         * error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>.
5429
5430         * strings.c (scm_string_ref): make the 2nd argument compulsory.
5431         previously it defaulted to zero for no good reason that I can see.
5432         use a local variable for SCM_INUM (k).  replace
5433         SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
5434
5435         (scm_makfromstr): cosmetic changes.
5436
5437         (scm_string): Accept only chars in the list, not strings, for
5438         conformance to R5RS (particularly for list->string, which is
5439         supposed to be the inverse of string->list.)  remove
5440         SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
5441         scm_makstr handles the cell allocation.  when reporting wrong-type
5442         arg, don't report the position as 1.
5443
5444         * posix.c (scm_init_posix): intern PIPE_BUF if it's defined.
5445
5446 2000-01-29  Gary Houston  <ghouston@arglist.com>
5447
5448         * posix.c (scm_pipe): rewrote the docstring.
5449
5450         * filesys.c (scm_select, retrieve_select_type, get_element,
5451         fill_select_type, set_element): modified so that Scheme
5452         "select" tests port buffers for the ability to provide input
5453         or accept output.  Previously only the underlying file descriptors
5454         were checked.  Rewrote the docstring.
5455
5456 Thu Jan 27 10:14:25 2000  Greg J. Badros  <gjb@cs.washington.edu>
5457
5458         * vectors.c, symbols.c, strorder.c: Documentation cut and pasted
5459         from Gregg Reynolds.  Thanks Gregg!
5460
5461 Thu Jan 27 09:59:38 2000  Greg J. Badros  <gjb@cs.washington.edu>
5462
5463         * strop.c (scm_i_index): Obfuscated commented-out SCM_DEFINE by
5464         adding "x" prefix to the line so that guile-func-name-check
5465         doesn't complain unnecessarily.
5466
5467 Wed Jan 26 17:33:52 2000  Greg J. Badros  <gjb@cs.washington.edu>
5468
5469         * throw.c: Factor out an #ifdef/#else/#endif choice more finely
5470         for maintainability.
5471
5472         * strop.c: Documentation added by Gregg A. Reynolds.   Pasted in
5473         from qdocs, RnRs.
5474
5475 Wed Jan 26 10:02:11 2000  Greg J. Badros  <gjb@cs.washington.edu>
5476
5477         * tag.c:  Added doc for `tag', but mark as deprecated since Mikael
5478         suggests removing tag.c altogether (and using a new `class-of'
5479         instead).
5480
5481         * strings.c:  Added documentation from Gregg A. Reynolds.  Edited
5482         a bit by me to use FOO instead of @var{foo} and to have the
5483         summary come before preconditions on input.  Also dropped trailing
5484         (rnrs) note.
5485
5486         * gsubr.c: Do not use SCM_DEFINE for `gsubr-apply'. Register the
5487         function with scm_make_subr_opt w/ last arg of 0 so it is not
5488         visible at the Scheme level. Mikael says that this is the right
5489         thing because the first arg to the proc is the guts of a compiled
5490         closure and shouldn't be exposed to the Scheme level.
5491
5492 Tue Jan 25 17:15:47 2000  Greg J. Badros  <gjb@cs.washington.edu>
5493
5494         * sort.c: typo in comment fixed.
5495
5496         * keywords.c: Added documentation.
5497
5498         * guardians.c: Added documentation (could be better).
5499
5500         * gc.c: Added docs for gc-set-debug-check-freelist.
5501
5502         * eq.c: Added docs for eq?, eqv? equal? abridged from R4RS.
5503
5504         * boolean.c: Added docs for `not', `boolean?' (by hand).
5505
5506 Tue Jan 25 13:28:56 2000  Greg J. Badros  <gjb@cs.washington.edu>
5507
5508         * random.c: Added documentation, from SLIB page:
5509         http://angela.ctrl-c.liu.se/~calle/scheme/slib_toc.html
5510
5511 Mon Jan 24 17:50:20 2000  Greg J. Badros  <gjb@cs.washington.edu>
5512
5513         * variable.c, version.c:  Added documentation, written by hand
5514         since I could not find anything already written that was
5515         relevant.
5516
5517 2000-01-23  Gary Houston  <ghouston@arglist.com>
5518
5519         * filesys.c (scm_chown): omit port/fdes support if HAVE_FCHOWN is
5520         not defined (thanks to Richard Y. Kim).
5521
5522 Thu Jan 20 13:00:38 2000  Greg J. Badros  <gjb@cs.washington.edu>
5523
5524         * Makefile.in: Removed, this is auto-generated.
5525
5526 Thu Jan 20 11:33:47 2000  Dirk Hermann <dirk@ida.ing.tu-bs.de> --applied 01/20/00 gjb
5527
5528         * list.c: Put some variable initialization code at the point of
5529         declaration; Added a comment for list*; Formatting changes.
5530
5531         * load.c: use SCM_NNULLP to make sure the end of a list is not
5532         reached yet.
5533
5534 2000-01-18  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
5535
5536         * backtrace.c (scm_display_error_message): Bugfix: Don't use
5537         result of scm_list_p as C boolean.
5538         (scm_display_error_message, scm_set_print_params_x): Use new
5539         validation macros. (Thanks to Dirk Herrmann.)
5540
5541         * net_db.c (scm_resolv_error): Cast result from hstrerror.
5542
5543         * strports.c (st_end_input): Inserted parenthesis to get operator
5544         grouping correct.
5545
5546         * list.h (scm_init_list): Removed SCM_P around prototypes.
5547
5548         * fports.c, list.c, numbers.c, ports.c, stime.c, symbols.c,
5549         filesys.c, posix.c: Converted docstrings to ANSI C format and
5550         escaped " occurring inside string literals.
5551
5552 Tue Jan 18 13:21:08 2000  Mikael Djurfeldt  <mdj@r11n07-s.pdc.kth.se>
5553
5554         * posix.c (scm_mknod): Escape " occuring inside docstring.
5555
5556 2000-01-18  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
5557
5558         * alist.c, chars.c, debug.c, dynl.c, dynwind.c, error.c, eval.c,
5559            evalext.c, filesys.c, gc.c, hash.c, hashtab.c, ioext.c,
5560            keywords.c, list.c, load.c, macros.c, net_db.c, numbers.c,

5564            symbols.c, throw.c, unif.c, vectors.c, version.c, vports.c,
5565            weaks.c: Converted docstrings to ANSI C format.
5566
5567         * filesys.c (scm_chmod), simpos.c (scm_system), version
5568         (scm_version), vports (scm_make_soft_port): Escape " occuring
5569         inside docstring.
5570
5571 Mon Jan 17 11:41:22 2000  Greg J. Badros  <gjb@cs.washington.edu>
5572
5573         * scm_validate.h: Added SCM_VALIDATE_ULONG_COPY,
5574         SCM_VALIDATE_LONG_COPY
5575
5576         * numbers.c: Use SCM_VALIDATE_ULONG_COPY, instead of
5577         SCM_VALIDATE_INUM_COPY to let bigger numbers be used.  Rename a
5578         couple of formal arguments (and fix their uses) to make arguments
5579         match the documentation.
5580
5581 2000-01-14    <mstachow@alum.mit.edu>
5582
5583         * Makefile.am: Augment path when running guile-doc-snarf so
5584         guile-func-name-check is found.
5585
5586 Fri Jan 14 09:34:55 2000  Greg J. Badros  <gjb@cs.washington.edu>
5587
5588         * scm_validate.h (SCM_NUM2LONG_DEF): Fix this macro to just use
5589         def, not SCM_MAKINUM(def);  thanks Janis Bzerins!
5590
5591 Wed Jan 12 00:06:53 2000  Greg J. Badros  <gjb@cs.washington.edu>
5592
5593         * net_db.c (s_scm_inet_makeaddr): Use SCM_NUM2ULONG since that's
5594         the way guile-1.3.4 worked, but #if 0 out the version using
5595         SCM_VALIDATE_INUM_COPY for stricter testing.
5596
5597 Tue Jan 11 18:24:18 2000  Greg J. Badros  <gjb@cs.washington.edu>
5598
5599         * guile-doc-snarf.in: Use new $fullfilename for running
5600         guile-func-name-check, and put "$fullfilename" and "$filename" in
5601         quotes at uses to make sure re-splitting on whitespace does not
5602         occur (so filenames w/ embedded whitespace would work okay, though
5603         I sure hope we never have to deal with that! :-) ).  Thanks to
5604         Mikael for pointing out the source_dir != build_dir was broken.
5605
5606 Tue Jan 11 17:42:40 2000  Greg J. Badros  <gjb@cs.washington.edu>
5607
5608         * scm_validate.h: Added SCM_NUM2LONG_DEF macro.  Make
5609         SCM_OUT_OF_RANGE use SCM_MAKINUM, not scm_long2num.  Added
5610         SCM_COERCE_ROSTRING macro.  Added SCM_VALIDATE_NONEMPTYLIST
5611         macro.  Fix SCM_VALIDATE_STRINGORSUBSTR macro to not use SLOPPY
5612         variants.
5613
5614         * ports.c (scm_port_closed_p): Validate that the arg is a PORT,
5615         then return whether it's an open port (was validating that it was
5616         an open port -- this was a bug I introduced back in December, but
5617         my careful reading of diffs caught it).
5618
5619         * numbers.c: Recombine the two conditional-compilation paths for
5620         all the log* primitives -- they were split based on #ifndef
5621         scm_long2num;  factored out a SCM_LOGOP_RETURN macro, and fixed
5622         some bugs and inconsistencies in the two sets of implementations.
5623         (scm_lognot) Fixed *atrocious* re-use of a SCM as an integer!
5624
5625         * ioext.c: Use SCM_ASSERT_RANGE in a couple places, and
5626         SCM_VALIDATE_INUM_COPY once where it should've been used.
5627
5628         * fluids.c (scm_internal_with_fluids): Use
5629         SCM_VALIDATE_LIST_COPYLEN.
5630
5631         * filesys.c: Use SCM_NUM2LONG instead of SCM_VALIDATE_INUM_COPY;
5632         this is questionable as it relaxes type safety, but other changes
5633         were useful and all SCM_NUM2LONG's should probably be
5634         revisited. Use SCM_OUT_OF_RANGE, SCM_WRONG_TYPE_ARG.
5635
5636         * evalext.c: line-break change on 1 line.
5637
5638         * eval.c (nconc2last): Takes a non-empty list as its first
5639         argument, not just a list.
5640
5641         * dynl.c: Use new SCM_COERCE_ROSTRING macro.

5643 Tue Jan 11 15:44:23 2000  Greg J. Badros  <gjb@cs.washington.edu>
5644
5645         * dynl.c, feature.c, filesys.c, fports.c, list.c, load.c,
5646         net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
5647         where possible.
5648
5649         * symbols.c (scm_sysintern0): Fixed the function name in a
5650         scm_misc_error invocation.
5651
5652         * print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
5653         use scm_return_first to ward off latent GC bug that Mikael caught.
5654
5655         * async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
5656         used before but should've been.
5657
5658 2000-01-12  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
5659
5660         * snarf.h (SCM_PROC1): Replaced SCM (*) (...) with
5661         SCM_FUNC_CAST_ARBITRARY_ARGS.
5662
5663 Tue Jan 11 13:44:07 2000  Greg J. Badros  <gjb@cs.washington.edu>
5664
5665         * guile-func-name-check.in: Added this script to statically check
5666         #define FUNC_NAME, #undef FUNC_NAME in the source.
5667
5668         * sort.c, posix.c: Fix #undef FUNC_NAME lines to not have trailing
5669         redundant comment, semicolon; caught by new guile-func-name-check
5670         script.
5671
5672         * debug.c: Fix mistaken #define FUNC_NAME for scm_make_iloc.
5673         Caught by new guile-func-name-check-script.
5674
5675         * Makefile.am: Added guile-func-name-check to bin_SCRIPTS
5676
5677         * ramap.c: Fix #if 0'd out code to be syntactically acceptable to
5678         guile-func-name-check.
5679
5680         * guile-doc-snarf.in: Run guile-func-name-check on the file before
5681         doing the snarf.
5682
5683 Tue Jan 11 11:31:10 2000  Greg J. Badros  <gjb@cs.washington.edu>
5684
5685         * fports.c, ports.c, ports.h, strports.c, vports.c: Make write
5686         port function take const void*, not void*.
5687
5688 Tue Jan 11 11:18:07 2000  Greg J. Badros  <gjb@cs.washington.edu>
5689
5690         * scm_validate.h, chars.c, ports.c, print.c, read.c, strings.c,
5691         strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
5692         SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY.  Change made for
5693         consistency with the other macros dealing with immediate
5694         characters.  (Similar to INT -> INUM change a week or so ago).
5695
5696 Tue Jan 11 10:41:46 2000  Greg J. Badros  <gjb@cs.washington.edu>
5697
5698         * dynl.c, error.c, eval.c, feature.c, filesys.c, fports.c, list.c, load.c,
5699         net_db.c, read.c, socket.c: Update error messages to use ~A for
5700         %s, ~S for %S to work with new `simple-format' format and be
5701         standardized better.
5702
5703         * print.h, print.c (scm_simple_format): Added `simple-format'
5704         primitive.  It's the old scm_display_error, with ARGS now a rest
5705         parameter, and the destination first instead of last (and a couple
5706         new capabilities inspired by `format' -- #t as destination means
5707         current-output-port, #f means return the formatted text as a
5708         string.
5709
5710         * gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
5711
5712         * backtrace.c (scm_display_error_message): Rewrote to use
5713         scm_simple_format() procedure.
5714
5715         * __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
5716
5717 2000-01-09  Marius Vollmer  <mvo@zagadka.ping.de>
5718
5719         Finally applied the libltdl patch from Thomas Tanner, with slight
5720         modifications.
5721
5722         * DYNAMIC-LINKING: Removed because it is obsolete.
5723         * dynl.c: Use ANSI prototypes.
5724         (sysdep_dynl_link): Use lt_dlopenext instead of lt_dlopen.
5725         * scmconfig.h.in: Do not change, as it is automatically generated.
5726
5727     1999-07-25  Thomas Tanner  <tanner@ffii.org>
5728
5729             * dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c: deleted
5730             (obsolete)
5731             * Makefile.am: likewise, add INCLTDL (libltdl headers) to
5732             INCLUDES, set dlpreopened files in LDFLAGS, link libguile
5733             against libltdl
5734             * dynl.c: use libltdl if DYNAMIC_LINKING is enabled,
5735             * guile.c: register preloaded modules
5736             * scmconfig.h.in: remove obsolete symbols
5737
5738 2000-01-09  Gary Houston  <ghouston@arglist.com>
5739
5740         * These changes should make it unnecessary to call tzset from
5741         Scheme after modifying the TZ environment variable, even if the
5742         system date facilities cache the value.
5743         * stime.c (setzone, scm_localtime): added comments.
5744         (tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
5745         (setzone): don't call tzset.
5746         (restorezone): call tzset only if HAVE_TZSET is defined.
5747         (scm_tzset): don't define if HAVE_TZSET not defined.  Change the
5748         doc string to indicate that this procedure isn't likely to do
5749         anything useful.
5750         (scm_localtime, scm_strftime, scm_mktime): call tzset if
5751         LOCALTIME_CACHE is defined.
5752
5753 2000-01-09  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
5754
5755         * posix.c (scm_sync): Return SCM_UNSPECIFIED.
5756
5757 2000-01-09  Gary Houston  <ghouston@arglist.com>
5758
5759         * eval.c: define scm_unbound_variable_key ('unbound-variable).
5760         scm_lookupcar1: throw an error with key 'unbound-variable instead
5761         of 'misc-error when an unbound variable is encountered.
5762
5763         * filesys.c (scm_mkdir, scm_rmdir, scm_getcwd, scm_select,
5764         scm_symlink, scm_readlink, scm_lstat),
5765         posix.c (scm_setpgid, scm_setsid, scm_ctermid, scm_tcgetpgrp,
5766         scm_tcsetpgrp, scm_uname, scm_setlocale, scm_mknod, scm_nice,
5767         scm_sync),
5768         simpos.c (scm_system),
5769         stime.c (scm_times, scm_strptime):
5770         move the HAVE_XXX feature tests out of the procedure bodies.
5771         don't use SCM_SYSMISSING.
5772         scm_validate.h (SCM_SYSMISSING): removed.
5773         error.h, error.c (scm_sysmissing): comment that this is deprecated.
5774         see ChangeLog entry for 1999-12-28.
5775
5776 Sat Jan  8 19:52:04 2000  Greg J. Badros  <gjb@cs.washington.edu>
5777
5778         * scm_validate.h (SCM_VALIDATE_BOOL_COPY): Fix typo.
5779
5780 Sat Jan  8 17:06:46 2000  Greg J. Badros  <gjb@cs.washington.edu>
5781
5782         * backtrace.c: Fix spelling typo in a comment.
5783
5784         * snarf.h: Use new SCM_DOCS macro to encapsulate the non SCM_INIT
5785         text.  Reformatted some of the expansions.
5786
5787 Fri Jan  7 15:50:46 2000  Greg J. Badros  <gjb@cs.washington.edu>
5788
5789         * scm_validate.h (SCM_OUT_OF_RANGE): Use scm_out_of_range_pos to
5790         report the position of the argument.
5791
5792         * error.h, error.c (scm_out_of_range_pos):  Added this function to
5793         take extra "pos" argument, the position number of the errant
5794         argument.
5795
5796         * debug.c: Use SCM_OUT_OF_RANGE instead of scm_out_of_range.
5797
5798         * snarf.h: Use SCM_HERE and SCM_INIT as names, not SCM_NOTSNARF
5799         and SCM_SNARFING.  Also put the %%% in the SCM_INIT since Mikael
5800         prefers that and I'm reasonably indifferent.
5801
5802 Fri Jan  7 15:03:32 2000  Greg J. Badros  <gjb@cs.washington.edu>
5803
5804         * snarf.h: Factor out differences between C++ and non-C++ into
5805         SCM_FUNC_CAST_ARBITRARY_ARGS macro.  Modify all the snarf macro
5806         definitions to use SCM_NOTSNARF and SCM_SNARFING macros (like
5807         Mikael's macros, below, but changed names and SCM_SNARFING no
5808         longer expands to include %%% -- that must appear in the argument
5809         so that the token appears at the call-site as a reminder).
5810
5811 2000-01-07  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
5812
5813         * snarf.h (SCM_INSITU, SCM_INIT): New snarf macros for use in user
5814         snarf macro definitions.
5815
5816 2000-01-06  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
5817
5818         * chars.c (scm_integer_to_char): Use Greg's nice
5819         SCM_VALIDATE_INUM_RANGE macro for argument checking for closer
5820         adherence to R5RS.
5821
5822 Thu Jan  6 11:48:49 2000  Greg J. Badros  <gjb@cs.washington.edu>
5823
5824         * *.c, snarf.h: Replace GUILE_PROC1 with SCM_DEFINE1 throughout.
5825
5826 Thu Jan  6 11:22:53 2000  Greg J. Badros  <gjb@cs.washington.edu>
5827
5828         * Makefile.am (ETAGS_ARGS): Switch to SCM_DEFINE, SCM_DEFINE1
5829         instead of GUILE_PROC.
5830
5831 Thu Jan  6 11:21:49 2000  Greg J. Badros  <gjb@cs.washington.edu>
5832
5833         * alist.c: Do not report mismatch errors on some uses of `tmp' (do
5834         this by using SCM_ARG2 instead of `2' in the SCM_VALIDATE_CONS
5835         macro call.
5836
5837 Thu Jan  6 09:54:33 2000  Dirk Herrmann <dirk@ida.ing.tu-bs.de> --gjb applied
5838
5839         * scm_validate.h: Remove some redundant NIMP tests.
5840
5841         * alist.c: minimize scope of the tmp variables, and initialize
5842         them when declared. The strange SCM_NIMP tests are replaced by
5843         SCM_CONSP tests that more closely reflect the intended semantics.
5844         However, we don't get a performance penalty here, because the
5845         SCM_CONSP test was performed by the ALISTCELL test anyway.  * The
5846         extremely ugly use of ASRTGO macros was removed: The calls to
5847         ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a
5848         label parameter that only exists when SCM_RECKLESS is not defined.
5849         This works, because ASRTGO itself is defined in a way that it only
5850         makes use of the label parameter if SCM_RECKLESS is not defined
5851         (shudder!).  Does guile make at all use of the possibility to
5852         define SCM_RECKLESS?  * Codesize is likely to be reduced, since
5853         instead of two calls to SCM_ASSERT performed by the ALISTCELL test
5854         we now only get one test.
5855
5856         * list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate.  Also use
5857         SCM_NULLP instead of SCM_IMP.  Drop use of "register" keyword on
5858         some variables in `list?'.  Fix `reverse' and `reverse!'
5859         primitives to handle improper lists better.
5860
5861 Wed Jan  5 11:24:53 2000  Greg J. Badros  <gjb@cs.washington.edu>
5862
5863         * *.[ch]: Whitespace changes -- added space after SCM_VALIDATE_*
5864         macros and SCM_DEFINE macros to match GNU coding standards.
5865
5866 Wed Jan  5 11:04:24 2000  Greg J. Badros  <gjb@cs.washington.edu>
5867
5868         * *.[ch]: Replace GUILE_PROC w/ SCM_DEFINE.
5869
5870 Wed Jan  5 10:59:06 2000  Greg J. Badros  <gjb@cs.washington.edu>
5871
5872         * *.[ch]:  Replace SCM_VALIDATE_INT w/ SCM_VALIDATE_INUM for
5873         better consistency with the names of other SCM_VALIDATE_ macros
5874         and better conformance to guile naming policy.
5875
5876 Wed Jan  5 10:50:39 2000  Greg J. Badros  <gjb@cs.washington.edu>
5877
5878         * ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a
5879         SCM_VALIDATE instead of 1 to avoid a check on the argument (since
5880         it's not the actual name of the formal).
5881
5882         * guile-snarf.awk.in: Do argument/number mismatch checking and
5883         print warnings in an Emacs compile-mode parseable format.
5884
5885         * struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/
5886         SCM_OUTOFRANGE as 3rd argument.
5887
5888         * random.c: Fix argument/number mismatch (that I introduced :-( ).
5889
5890         * __scm.h: Do not #define SCM_ARG* when snarfing;
5891         lets us distinguish between 1 and SCM_ARG1 when snarfing as only
5892         the former (using the number) requires the argument to match the
5893         formal in the current argument snarfing check.
5894
5895         * snarf.h: Give new definition of SCM_ASSERT when in
5896         snarfing mode to output a lexically-identifiable sequence that the
5897         guile-snarf.awk script uses to verify argument/position matching.
5898
5899         * ramap.c: Remove extraneous #undef FUNC_NAME.
5900
5901 Wed Jan  5 08:36:38 2000  Greg J. Badros  <gjb@cs.washington.edu>
5902
5903         * guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the
5904         current version of the same functionality; it writes the .x output
5905         to stdout instead of directly into the file.
5906
5907 Wed Jan  5 08:15:04 2000  Greg J. Badros  <gjb@cs.washington.edu>
5908
5909         * unif.c, symbols.c, strings.c, stacks.c, random.c, print.c,
5910         posix.c:  Eliminated a bunch of SCM_NIMP(..)s that are now
5911         redundant with the safer macros.  Patch from Dirk Hermann applied
5912         by hand. Thanks Dirk!
5913
5914         * scm_validate.h: Added SCM_VALIDATE_VECTOR_OR_DVECTOR for some
5915         uses in random.c.
5916
5917         * ramap.c: whitespace change.
5918
5919 Tue Jan  4 14:21:35 2000  Greg J. Badros  <gjb@cs.washington.edu>
5920
5921         * options.c, objects.c, keywords.c, gc.c: Some redundant SCM_NIMP
5922         removals from Dirk Hermann.
5923
5924         * alist.c: Rename formals to match the parameter names in the
5925         documentation, updates to documentation.  Thanks Dirk Hermann!
5926
5927 2000-01-04  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
5928
5929         * eval.c (SCM_CEVAL): Reverse order of
5930         scm_stack_checking_enabled_p and SCM_STACK_OVERFLOW_P
5931         (Thanks to Brad Knotwell.)
5932
5933 Mon Jan  3 08:30:02 2000  Greg Harvey  <Greg.Harvey@thezone.net> (applied --01/03/00 gjb)
5934
5935         * gc.c (scm_debug_newcell): Added SCM_SETCAR of the newly
5936         allocated cell.
5937
5938         * pairs.h: Added a comment about the need for the SCM_SETCAR in
5939         SCM_NEWCELL macro.
5940
5941 Mon Jan  3 08:25:19 2000  Greg J. Badros  <gjb@cs.washington.edu>
5942
5943         * dynl-vms.c, debug.c, coop-threads.c, backtrace.c, eval.c: More
5944         SCM_NIMP tests that were redundant are now eliminated.  Patches
5945         from Dirk Hermann applied by hand.
