libguile/ChangeLog

   1 2000-06-27  Dirk Herrmann  <D.Herrmann@tu-bs.de>
   2
   3         * async.c (scm_init_async):  Switch to standard way of smob
   4         initialization.
   5
   6 2000-06-21  Michael Livshin  <mlivshin@bigfoot.com>
   7
   8         * guile-doc-snarf.in: use cut instead of sed, that's much much
   9         faster.  also, don't call basename more than needed.  and, to gain
  10         a couple of microseconds more, don't call cat needlessly.  (thanks
  11         to Brad Knotwell).
  12
  13 2000-06-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>
  14
  15         * guile-snarf.awk.in, guile-snarf.in, snarf.h:  Rename SCM__I to
  16         SCM_SNARF_INIT_START, SCM__D to SCM_SNARF_DOC_START, SCM__S to
  17         SCM_SNARF_DOCSTRING_START and SCM__E to SCM_SNARF_DOCSTRING_END.
  18
  19 2000-06-21  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
  20
  21         * eval.c, eval.h (scm_top_level_lookup_closure_var): Added.
  22         #include "libguile/fluids.h".
  23
  24         * eval.h (SCM_TOP_LEVEL_LOOKUP_CLOSURE): New macro which replaces
  25         SCM_CDR (scm_top_level_lookup_closure_var) everywhere.
  26
  27         * root.h (scm_top_level_lookup_closure_var,
  28         scm_system_transformer): Removed.  (It's no sense in having the
  29         *variable* be a "fluid".)
  30
  31         * root.c (mark_root): Removed marking of
  32         s->top_level_lookup_closure_var and s->system_transformer.
  33
  34         * modules.c (scm_selected_module): the_module is now a fluid.
  35
  36 2000-06-20  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
  37
  38         * gc.h, tags.h: Be kind to compilers which must see hash signs in
  39         column 0.  (Thanks to Ian Grant.)
  40
  41         * numbers.h: Put #ifdef HAVE_LONG_LONGS around declarations using
  42         the long_long type.  (Thanks to Bernard Urban.)
  43
  44 2000-06-20  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
  45
  46         * gc.c, gc.h (scm_default_init_heap_size_1,
  47         scm_default_min_yield_1, scm_default_init_heap_size_2,
  48         scm_default_min_yield_2, scm_default_max_segment_size): New global
  49         variables.  Can be customized by the application before booting
  50         Guile.  (We might want to be able to control these parameters
  51         dynamically through the "options interface" in the future, but
  52         note that that is additional functionality.  Here we're giving
  53         default values which the environment variables can override.)
  54
  55         * list.c (scm_cons_star): Updated comment.
  56
  57         * smob.h: Changed comments for scm_make_smob_type and
  58         scm_make_smob_type_mfpe, warning that the latter might be
  59         deprecated in a future release.
  60
  61 2000-06-19  Dirk Herrmann  <D.Herrmann@tu-bs.de>
  62
  63         * list.[ch] (scm_cons_star/cons*):  Renamed from
  64         scm_list_star/list*.
  65
  66         * list.[ch] (scm_list_star/list*):  Provided as a deprecated alias
  67         for scm_cons_star/cons*.
  68
  69         * gc.c (scm_protect_object):  Updated comment.
  70
  71         * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX):  Removed.
  72
  73         * tags.h (SCM_UNPACK_CAR, SCM_NDOUBLE_CELLP):  Removed.
  74
  75 2000-06-19  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
  76
  77         * init.c, init.h (scm_initialized_p): Renamed from `initialized'
  78         and made global.
  79
  80         * gdbint.c (gdb_print): Print warning instead of calling scm_write
  81         if Guile isn't yet initialized.
  82
  83         * print.c (scm_current_pstate, scm_make_print_state): Simplified
  84         tests, using the assumption that Guile has been initialized.
  85
  86 Sun Jun 18 14:45:21 2000  Greg J. Badros  <gjb@cs.washington.edu>
  87
  88         * print.c (s_scm_current_pstate): Do not segfault when the
  89         print_state_pool is unitialized in `current-pstate', and better
  90         verify its state before altering it in scm_make_print_state().
  91
  92 2000-06-18  Michael Livshin  <mlivshin@bigfoot.com>
  93
  94         * scmsigs.c (s_scm_sigaction): guard the SIGIOT case with an
  95         #ifdef -- it's missing on at least one platform.  (thanks to
  96         Jan Nieuwenhuizen).
  97
  98 2000-06-16  Dirk Herrmann  <D.Herrmann@tu-bs.de>
  99
 100         * list.c (list*):  Added documentation from common-list.scm.
 101
 102 2000-06-15  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 103
 104         * gc.c (scm_unprotect_object):  The reference count is guaranteed
 105         to be a positive number.
 106
 107 2000-06-15  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 108
 109         * eval.c: Updated comment above scm_map.
 110
 111 2000-06-14  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 112
 113         * gc.c (scm_protect_object): Avoid looking up the object handle
 114         twice.
 115         (scm_unprotect_object): Abort if scm_unprotect_object is called on
 116         an unprotected object.
 117
 118 2000-06-14  Michael Livshin  <mlivshin@bigfoot.com>
 119
 120         * gc.c (scm_unprotect_object): fix a nasty typo bug (thanks to
 121         Dirk Herrmann).
 122
 123 2000-06-14  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 124
 125         * socket.c (scm_getsockopt): Changed type for `optlen' from int to
 126         size_t.
 127         (scm_accept, scm_getsockname, scm_getpeername, scm_recvfrom):
 128         Ditto for `tmp_size'.
 129         (scm_addr_buffer_size): Changed type from int to size_t.
 130
 131         * random.c: #include <string.h>.  (Needed by memcpy.)
 132
 133         * guile-snarf.awk.in: Replace the dot_doc_file arg with "-",
 134         indicating stdin, instead of "" and don't reset ARGC.  This is a
 135         workaround for `nawk' in AIX 4.3 on RS6000 but, as far as I know,
 136         it is correct, and perhaps even better.
 137
 138 2000-06-14  Gary Houston  <ghouston@arglist.com>
 139
 140         * scmsigs.c (scm_init_scmsigs): if HAVE_SIGINTERRUPT is not
 141         defined, add SA_RESTART to the sigaction flags correctly
 142         (thanks to Dale P. Smith).
 143
 144 2000-06-13  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 145
 146         * strings.c: #include <string.h>. (Thanks to Bill Schottstaedt.)
 147
 148         * net_db.c (scm_resolv_error): Only use macro NETDB_INTERNAL if
 149         defined. It isn't on sgi irix 5.3.  (Thanks to Bill Schottstaedt.)
 150
 151         * Makefile.am (.c.doc): Pipe output (the .x contents) to /dev/null.
 152
 153 2000-06-13  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 154
 155         * fports.c (scm_setvbuf): Use `free' instead of `scm_must_free'
 156         since read and write buffers are allocated by `malloc'.
 157
 158         * Makefile.am: Removed old test code.
 159
 160         * gh_test_c.c, gh_test_repl.c: Removed.
 161
 162 2000-06-12  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 163
 164         * iselect.c (SCM_NLONGBITS): Add workaround for the Sun 4.2
 165         compiler.
 166
 167         * inet_aton.c (inet_aton): Cast init value for `cp'.
 168
 169         * ramap.c (s_scm_array_fill_x): Cast `ve' properly in case
 170         `scm_tc7_uvect'.
 171
 172         * symbols.c (scm_intern_obarray_soft,
 173         scm_sysintern0_no_module_lookup): Cast `name' to unsigned char ptr
 174         in calls to scm_strhash.
 175
 176         * strports.c (st_resize_port): Substituted SCM_UCHARS for
 177         SCM_CHARS.
 178         (st_write): Cast argument to strncpy to char ptr.
 179         (scm_mkstrport): Substituted SCM_ROUCHARS for SCM_ROCHARS.
 180         (scm_strport_to_string): Cast argument to scm_makfromstr to char
 181         ptr.
 182
 183         * ports.c (scm_ungetc): Cast value to unsigned char ptr before
 184         storing in putback_buf.
 185         (scm_unread_string): Substituted SCM_ROCHARS for SCM_ROUCHARS.
 186
 187         * ioext.c (s_scm_read_line): Cast result of call to
 188         scm_do_read_line to unsigned char ptr.
 189
 190         * gdbint.c (SEND_STRING): Cast argument to char pointer.
 191
 192         * fports.c (fport_flush): Declare `ptr' as unsigned char (was
 193         char).
 194
 195         * Makefile.am (DOT_DOC_FILES): List doc-files explicitly.  (We
 196         shouldn't use Make rules which aren't supported by most Make
 197         programs.)
 198         (OMIT_DEPENDENCIES): Defined to "libguile.h ltdl.h".  (We don't
 199         want these dependencies recorded, since they would get bogus
 200         relative paths; libguile.h is only used in gh.h and guile.c.)
 201         (EXTRA_DOT_X_FILES, EXTRA_DOT_DOC_FILES): New variables.
 202         (guile-procedures.txt): Depend on EXTRA_DOT_DOC_FILES.
 203         (modinclude_HEADERS): Removed kw.h.
 204
 205         * guile-snarf.in: Change regexp "^SCM__I" --> "^ *SCM__I".
 206         (The preprocessor might insert spaces before the identifier.)
 207
 208         * snarf.h (SCM_SNARF_HERE, SCM_SNARF_INIT, SCM_SNARF_DOCS):
 209         Renamed from SCM_HERE, SCM_INIT, SCM_DOCS.
 210
 211         * smob.h (scm_smobfuns): Removed deprecated type.
 212
 213         * smob.c, smob.h (scm_newsmob): Removed deprecated function.
 214         (Replaced by `scm_make_smob_type'.)
 215
 216         * keywords.c (scm_tc16_kw): Removed deprecated type.
 217         (Replaced by scm_tc16_keyword.)
 218
 219         * kw.h: Removed deprecated header file.
 220
 221         * evalext.c (serial-map): Removed deprected alias for scm_map.
 222         (Has been replaced by `map-in-order'.)
 223
 224         * ramap.c (serial-array-copy!, serial-array-map!): Removed
 225         depracted aliases.  (Replaced by `array-copy-in-order!' and
 226         `array-map-in-order'.)
 227
 228 2000-06-11  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 229
 230         * gc.h (SCM_VALIDATE_CELL): Rewritten.
 231         (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
 232         SCM_SET_CELL_OBJECT): Use new version of SCM_VALIDATE_CELL.
 233         (Thanks to Han-Wen Nienhuys.)
 234
 235 2000-06-10  Michael Livshin  <mlivshin@bigfoot.com>
 236
 237         * guile-doc-snarf.in: don't pipe the CPP output right into sed --
 238         write it to the temp file first and check the CPP return code.
 239         (I introduced this bug earlier, and this probably caused people
 240         with non-GNU C preprocessors to get empty *.x files and not to
 241         have the build fail right away...).
 242
 243         * scmsigs.c (s_scm_sigaction): guard the SIGSYS case with an ifdef
 244         -- at least my libc5-based Linux system doesn't define SIGSYS.
 245
 246 2000-06-08  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 247
 248         * snarf.h, guile-snarf.awk.in, guile-snarf.in: Replaced snarf
 249         markers with identifiers (SCM__I, SCM__D, SCM__S, SCM__E).
 250         (Thanks to Bernard Urban.)
 251
 252 2000-06-06  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 253
 254         * modules.c (scm_system_module_env_p): Fixed detection of system
 255         modules.
 256
 257 2000-06-06  Marius Vollmer  <mvo@zagadka.ping.de>
 258
 259         * scmsigs.c (scm_sigaction): Silently ignore setting handlers for
 260         `program error signals' because they can't currently be handled by
 261         Scheme code.
 262
 263 2000-06-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 264
 265         * procs.h (SCM_SET_SUBRF):  Added.
 266
 267         * procs.c (scm_make_subr_opt):  Don't assign to SCM_SUBRF, use
 268         SCM_SET_SUBRF instead.  Thanks to Bernard Urban for the bug
 269         report.
 270
 271 2000-06-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 272
 273         * gc.h (SCM_CARLOC, SCM_CDRLOC):  Don't take the address of a SCM
 274         value.
 275
 276         * sort.c (scm_sorted_p, scm_merge, scm_merge_list_x,
 277         scm_merge_list_step):  Don't take the address of SCM_CAR.  Use
 278         SCM_CARLOC instead.  Thanks to Bernard Urban for the bug report.
 279
 280 2000-06-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 281
 282         * boolean.h (SCM_TRUE_P):  Removed, as people might use it as a
 283         replacement for !SCM_FALSEP.
 284
 285         * backtrace.c (display_error_body), boolean.h (SCM_BOOLP), gc.c
 286         (scm_unhash_name), gh_data.c (gh_module_lookup), load.c
 287         (scm_primitive_load), print.c (scm_simple_format), procs.c
 288         (scm_procedure_documentation), procs.h (SCM_TOP_LEVEL), ramap.c
 289         (scm_array_fill_int), scmsigs.c (scm_sigaction), stacks.c
 290         (narrow_stack, scm_make_stack, scm_stack_id), symbols.c
 291         (scm_string_to_obarray_symbol), throw.c (scm_catch,
 292         scm_lazy_catch, scm_ithrow), unif.c (scm_make_uve, scm_array_p,
 293         scm_array_set_x, scm_bit_set_star_x, scm_bit_count_star),
 294         validate.h (SCM_VALIDATE_BOOL_COPY, SCM_VALIDATE_PROC):  Replace
 295         uses of SCM_TRUE_P (x) with SCM_EQ_P (x, SCM_BOOL_T).
 296
 297 2000-06-04  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 298
 299         * eval.c (scm_badformalsp): New static function.
 300         (SCM_CEVAL): Check arguments for procedure-with-setter closures.
 301         (Thanks to Keisuke Nishida.)
 302
 303         The major reason for Guile's slow loading speed has been the fact
 304         that a chain of Scheme level procedures has been evaluated for
 305         every top-level symbol lookup during the first pass through the
 306         code.
 307
 308         The following is a kludge which I suggested four years ago, and
 309         which I've repeatedly suggested since.  Personally, I've never
 310         been bothered by Guile's slow loading speed, so I thought I would
 311         let someone else do it...
 312
 313         But since the new environments will be included first in
 314         Guile-1.5, I thought it would make people happy to get the kludge
 315         into 1.4.
 316
 317         * modules.c: Added #include "libguile/vectors.h";
 318         Added #include "libguile/hashtab.h";
 319         Added #include "libguile/struct.h";
 320         Added #include "libguile/variable.h";
 321         Capture Scheme level `module-make-local-var!' to be used in the
 322         standard eval closure.
 323         (scm_standard_eval_closure): New primitive.
 324
 325         * modules.h (scm_standard_eval_closure): Declare.
 326
 327         * eval.c (scm_lookupcar): Test for !SCM_CONSP (SCM_CAR (env))
 328         instead of SCM_TRUE (scm_procedurep (SCM_CAR (env))).
 329
 330         * symbols.c (scm_sym2vcell): Bypass dispatch in the evaluator for
 331         standard eval closures.
 332
 333         * variable.c: Code layout fixes.
 334
 335 2000-06-03  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 336
 337         * Makefile.am: Added LIBS line to libpath which accidentally
 338         disappeared in the change of 2000-06-01.
 339         (Thanks to Dale P. Smith.)
 340
 341 2000-06-03  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 342
 343         * scmsigs.c (scm_segfault): Removed.  (Was probably added by
 344         mistake since it is not mentioned in ChangeLog.)
 345
 346         * gc.h (SCM_VALIDATE_CELL): Cast result to (void) in order to
 347         avoid compiler warnings in gcc.  (Does this work for other
 348         compilers?)
 349
 350 2000-06-03  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 351
 352         * gc.h (SCM_VALIDATE_CELL): Don't "use" the value returned by
 353         abort ().
 354         (SCM_CARLOC, SCM_CDRLOC): Define directly instead of using
 355         SCM_CELL_OBJECT_0 and SCM_CELL_OBJECT_1.  It's not correct to take
 356         the address of these expressions since they use SCM_VALIDATE_CELL.
 357         (Thanks to Bernard Urban.)
 358
 359         * dynl.c: Changed #include <ltdl.h> --> #include

 362 2000-06-01  Craig Brozefsky  <craig@red-bean.com>
 363
 364         * Makefile.am: libguile_la_LDFLAGS gets -version-info args
 365         from GUILE-VERSION definition of LIBGUILE version.  Added to
 366         libpath.h definitions for guileversion and libguileversion which
 367         both get their values from GUILE-VERSION definition.
 368
 369 2000-05-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 370
 371         * numbers.h (SCM_BIGP):  Don't use SCM_SMOB_PREDICATE in header
 372         file:  Code using numbers should not be required to include
 373         smob.h.
 374
 375 2000-05-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 376
 377         * coop-threads.c.cygnus, coop-threads.h.cygnus, fsu-pthreads.h,
 378         mit-pthreads.c, mit-pthreads.h:  Deleted.
 379
 380         * Makefile.am (EXTRA_DIST), scmsigs.c, threads.[ch]:  Drop
 381         references to deleted files and fsu/mit thread support in
 382         general.
 383
 384 2000-05-29  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 385
 386         * hooks.c (symbol_name, scm_create_hook):  Restored the original
 387         behaviour of scm_create_hook.  Changing it was bad as Carl
 388         R. Witty has pointed out.
 389
 390         * gc.c (scm_init_gc):  We can still rely on scm_create_hook to
 391         protect the object.
 392
 393 2000-05-26  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 394
 395         * gc.c (scm_init_gc):  Protect scm_after_gc_hook, since this will
 396         soon not be done by scm_create_hook any longer.
 397
 398         * hooks.c (make_hook, print_hook, scm_create_hook,
 399         scm_make_hook_with_name, scm_make_hook), hooks.h (SCM_HOOK_NAME,
 400         SCM_HOOK_PROCEDURES, SCM_SET_HOOK_PROCEDURES,
 401         scm_make_hook_with_name), init.c (scm_boot_guile_1):  Hooks no
 402         longer have names.  As an intermediate solution, the name
 403         predicate is emulated via object properties, but use of this
 404         feature is deprecated.
 405
 406         * hooks.h (scm_free_hook):  Removed, as it is never defined.
 407
 408 2000-05-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 409
 410         * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_FIXABLE):
 411         Un-deprecated since otherwise user code can't determine whether a
 412         number fits into an inum any longer.  The names should be changed
 413         some time, though.
 414
 415         * numbers.c (scm_big2inum):  Eliminated use of SCM_UNEGFIXABLE.
 416
 417         * tags.h (SCM_UNPACK_CAR):  Deprecated.
 418
 419 2000-05-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 420
 421         * filesys.h (SCM_OPDIRP), fluids.h (SCM_FLUIDP, SCM_FLUID_NUM),
 422         fports.h (SCM_OPFPORTP, SCM_OPINFPORTP, SCM_OPOUTFPORTP), hooks.h

 424         numbers.h (SCM_NUMP, SCM_BIGSIGN, SCM_BDIGITS, SCM_NUMDIGS):
 425         Replace SCM_UNPACK_CAR appropriately.  Don't access cells via
 426         SCM_{SET}?C[AD]R unless they are known to be cons cells.
 427
 428         * gc.c (scm_heap_seg_data_t, scm_mark_locations, scm_cellp,
 429         init_heap_seg):  Remove unused struct member variable 'valid'.
 430
 431 2000-05-24  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 432
 433         * fports.c (fport_write), ports.c (scm_markstream, scm_port_mode,
 434         scm_print_port_mode), ports.h (SCM_OPPORTP, SCM_OPINPORTP,
 435         SCM_OPOUTPORTP, SCM_INPUT_PORT_P, SCM_OUTPUT_PORT_P, SCM_OPENP),
 436         procs.h (SCM_CLOSCAR), unif.h (SCM_ARRAY_NDIM, SCM_ARRAY_CONTP),
 437         variable.h (SCM_VARIABLEP):  Replace SCM_UNPACK_CAR
 438         appropriately.
 439
 440 2000-05-23  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 441
 442         * gc.c (free_list_length), hash.c (scm_hasher), macros.c
 443         (scm_macro_type), objects.c (scm_class_of), options.c
 444         (scm_options), print.c (scm_iprin1), strports.c (st_seek), throw.c
 445         (SCM_LAZY_CATCH_P):  Replace SCM_UNPACK_CAR appropriately.
 446
 447 2000-05-23  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 448
 449         * eval.c (scm_macroexp, SCM_CEVAL, scm_force), tags.h:  Replace
 450         SCM_UNPACK_CAR with SCM_CELL_TYPE or SCM_CELL_WORD_0.
 451
 452         * eval.c (scm_force):  Add documentation.
 453
 454         * eval.c (scm_force, scm_cons_source):  Don't access cells via
 455         SCM_{SET}?C[AD]R unless they are known to be cons cells.
 456
 457 2000-05-23  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 458
 459         * strings.h (SCM_NSTRINGP, SCM_NRWSTRINGP), tags.h
 460         (SCM_NDOUBLE_CELLP), vectors.h (SCM_NVECTORP):  Deprecated.
 461
 462         * gc.c (scm_igc), gc.h (SCM_PTR_MASK, SCM_PTR_LT):  Removed #ifdef
 463         nosve #endif conditionally compiled code.
 464
 465 2000-05-23  Michael Livshin  <mlivshin@bigfoot.com>
 466
 467         * gc.c (scm_heap_seg_data_t): fixed comment for the `span' member.
 468
 469 2000-05-22  Michael Livshin  <mlivshin@bigfoot.com>
 470
 471         * guile-doc-snarf.in: put the preprocessed file through sed to
 472         trim all lines to 1024 chars.  I hope it doesn't break anybody's
 473         sed.  we'll see.  (note: this is lossy trimming, i.e. the spill
 474         isn't wrapped around but actually chopped off.  this seemed to me
 475         safe because the current snarfer doesn't understand multi-line
 476         cookies anyway.  in the long term, it would be nice not to depend
 477         on AWK for anything.)
 478
 479         * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): reverted
 480         the previous change to this macros, after deciding to torture the
 481         snarfer instead.
 482
 483 2000-05-21  Michael Livshin  <mlivshin@bigfoot.com>
 484
 485         * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): brought
 486         the yucky, ugly and nasty conditional compilation back.  sorry,
 487         but it was either that or requiring GAWK to build Guile.
 488         (lots of places): removed the code that implemented the old GC
 489         scheme.
 490
 491         * init.c (scm_boot_guile_1): removed the code conditioned on
 492         !GUILE_NEW_GC_SCHEME.
 493
 494         * __scm.h: (GUILE_NEW_GC_SCHEME): removed.
 495
 496         * gc.c (scm_protect_object, scm_unprotect_object): change the
 497         implementation to more efficient (at least in the time complexity
 498         sense).  the calls should now also be thread-safe -- I suspect
 499         that people expect them to be.  (thanks to Han-Wen Nienhuys)
 500         (lots of places): removed the code that implemented the old GC
 501         scheme.
 502
 503         * hashtab.c (scm_hash_fn_create_handle_x): add missing
 504         SCM_REALLOW_INTS before return.  I really wonder about the
 505         possible interactions between hashtables, threads & GC.  it
 506         doesn't look healthy at all.
 507
 508 2000-05-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 509
 510         * unif.c (scm_bit_count):  Fixed the parameter checks.  Thanks to
 511         Dale P. Smith.
 512
 513 2000-05-19  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 514
 515         * __scm.h (SCM_DEBUG_CELL_ACCESSES), gc.h (SCM_):  Added as a new
 516         debug option to verify all accesses to cells actually access
 517         objects on the heap.
 518
 519         * gc.h (SCM_VALIDATE_CELL):  Added.  Only performs validation if
 520         SCM_DEBUG_CELL_ACCESSES is set to 1.
 521
 522         (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
 523         SCM_SET_CELL_OBJECT):  Use SCM_VALIDATE_CELL to check every cell
 524         that is accessed.
 525
 526 2000-05-19  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 527
 528         * gh_data.c (gh_scm2chars, gh_scm2shorts, gh_scm2longs,
 529         gh_scm2floats, gh_scm2doubles):  Change !SCM_NIMP to SCM_IMP.
 530
 531         * gc.c (scm_cellp):  Fixed and simplified.
 532
 533         * throw.c (JBJMPBUF, SETJBJMPBUF, SCM_JBDFRAME, SCM_SETJBDFRAME,
 534         make_jmpbuf, scm_init_throw):  Now using double cells to represent
 535         jump buffers when using debug extensions.
 536
 537         (freejb):  Removed.
 538
 539 2000-05-18  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 540
 541         * gh.h gh_data.c gh_funcs.c (gh_new_procedure*, gh_chars2byvect,
 542         gh_shorts2svect, gh_longs2ivect, gh_ulongs2uvect, gh_floats2fvect,
 543         gh_doubles2dvect, gh_doubles2scm, gh_define, gh_lookup,
 544         gh_module_lookup):  Accept const pointers as parameters.
 545
 546         * gh.h gh_data.c (gh_int2scmb):  Deprecated.
 547
 548 2000-05-18  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 549
 550         * __scm.h (SCM_DEBUG_REST_ARGUMENT):  Renamed from
 551         SCM_DEBUG_REST_ARGUMENTS in order to clarify that we don't test
 552         the actual arguments in the list, but rather the rest argument as
 553         a list of arguments.
 554
 555         * validate.h (SCM_VALIDATE_REST_ARGUMENT):  Added.
 556
 557         * async.c (scm_noop), eval.c (scm_map, scm_for_each), list.c
 558         (scm_list_star, scm_append, scm_append_x), ports.c
 559         (scm_close_all_ports_except), ramap.c (scm_array_map_x,
 560         scm_array_for_each), regex-posix.c (scm_make_regexp), stacks.c
 561         (scm_make_stack), strings.c (scm_string_append), struct.c
 562         (scm_make_struct, scm_make_vtable_vtable):  Validate rest arguments.
 563
 564         * dynl.c (DYNL_GLOBAL, sysdep_dynl_link, kw_global, sym_global,
 565         scm_dynamic_link, scm_init_dynamic_linking), dynl.h
 566         (scm_dynamic_link):  Removed possibility to pass flags to
 567         scm_dynamic_link, as it had no effect anyway.
 568
 569         * filesys.c (scm_fcntl):  Made single optional rest argument into
 570         a standard optional argument.
 571
 572         * hooks.c (scm_run_hook):  A list of rest arguments is never
 573         SCM_UNBNDP.
 574
 575         * list.c (scm_append, scm_append_x), stacks.c (scm_make_stack),
 576         strings.c (scm_string_append):  Don't perform half-hearted checks
 577         to see whether the rest argument forms a proper list any more, use
 578         SCM_VALIDATE_REST_ARGUMENTS instead.
 579
 580         * ports.c (scm_close_all_ports_except):  Accept empty list of rest
 581         arguments.
 582
 583         * posix.c (scm_convert_exec_args), print.c (scm_simple_format):
 584         Simplify verification of rest argument.
 585
 586         * stacks.c (scm_make_stack), stacks.h (scm_make_stack), throw.c
 587         (ss_handler, handler_message):  Make first mandatory rest argument
 588         of scm_make_stack into a standard mandatory argument.
 589
 590         * unif.c (scm_transpose_array, scm_enclose_array,
 591         scm_array_in_bounds_p), unif.h (scm_transpose_array,
 592         scm_enclose_array, scm_array_in_bounds_p):  Make first mandatory
 593         rest argument into a standard mandatory argument.
 594
 595 2000-05-17  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 596
 597         * __scm.h:  Added SCM_DEBUG as default debug option. (Thanks to
 598         Keisuke Nishida for the suggestion.)  Added debug option
 599         SCM_DEBUG_REST_ARGUMENTS.
 600
 601         * eval.c (scm_map, scm_for_each):  Make sure all lists have the
 602         same length.  Also, removed redundant parameter checks.
 603
 604 2000-05-16  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 605
 606         * Makefile.am:  Let 'make clean' remove *.x and *.doc files.
 607
 608         * __scm.h:  Improved explanation of giving options to make.
 609
 610         * __scm.h (SCM_DEBUG_TYPING_STRICTNESS), tags.h
 611         (SCM_STRICT_TYPING, SCM_DEBUG_TYPING_STRICTNESS):  Renamed
 612         SCM_STRICT_TYPING to SCM_DEBUG_TYPING_STRICTNESS and moved the
 613         corresponding declaration and comment to __scm.h.
 614
 615         * _scm.h (errno), gc.h (SCM_CELLPTR, SCM_PTR_LT), numbers.c
 616         (scm_remainder, scm_modulo), numbers.h (SCM_SRS, SCM_MAKINUM,
 617         SCM_INUM):  Removed conditionally compiled code for Turbo C.
 618
 619         * gdbint.c (gdb_maybe_valid_type_p):  Eliminated call to scm_tag.
 620         That check can be assumed to be redundant except for very rare
 621         conditions that actually indicate broken heap data.
 622
 623 2000-05-16  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 624
 625         * numbers.c (scm_logcount, scm_integer_length):  Reordered
 626         dispatch sequence.
 627
 628 2000-05-15  Gary Houston  <ghouston@arglist.com>
 629
 630         * stime.c (scm_strftime): don't reset TZ if zone is an empty
 631         string.  append a "0" to the zone for TZ.
 632
 633 2000-05-15  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 634
 635         * numbers.c (scm_logbit_p, scm_bit_extract):  Reordered dispatch
 636         sequence.
 637
 638         (scm_bit_extract):  Fixed handling of bignums.
 639
 640 2000-05-15  Dirk Herrmann  <D.Herrmann@tu-bs.de>

 650         (scm_tc16_flo, scm_tc_flo, scm_tc_dblr, scm_tc_dblc):  Wrapped
 651         deprecated code between #if (SCM_DEBUG_DEPRECATED == 0) #endif.
 652
 653         * fports.c (scm_fport_buffer_add), ports.c (scm_input_port_p,
 654         scm_output_port_p), print.c (scm_get_print_state), validate.h
 655         (SCM_VALIDATE_CHAR):  Replace use of deprecated macros
 656         SCM_INPORTP, SCM_OUTPORTP, SCM_ICHRP by SCM_INPUT_PORT_P,
 657         SCM_OUTPUT_PORT_P, SCM_CHARP, respectively.
 658
 659 2000-05-14  Gary Houston  <ghouston@arglist.com>
 660
 661         * stime.c (scm_strftime): if HAVE_TM_ZONE is not defined, hack the
 662         TZ environment variable so that the %Z format returns the zone
 663         from the input vector instead of the system default.
 664
 665         from Keisuke Nishida:
 666         * fports.c (scm_setvbuf): minor docstring fix.
 667         * ports.h (scm_generic_fgets): obsolete prototype deleted.
 668
 669 2000-05-11  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 670
 671         * __scm.h:  Added new section for debugging options.
 672
 673         (SCM_DEBUG_DEPRECATED):  If 1, no deprecated code is included to
 674         help developers to get rid of references to deprecated code.
 675
 676         * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_UNEGFIXABLE,
 677         SCM_FIXABLE, SCM_FLOBUFLEN):  These macros are no longer provided
 678         as part of the interface and are marked as deprecated in the
 679         header file.
 680
 681         * numbers.c (scm_make_real, scm_make_complex):  Inlined the
 682         corresponding macros SCM_NEWREAL and SCM_NEWCOMPLEX,
 683         respectively.
 684
 685         * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX, SCM_INEXP, SCM_CPLXP,
 686         SCM_REAL, SCM_IMAG, SCM_REALPART, scm_makdbl, SCM_SINGP,
 687         SCM_NO_BIGDIG, SCM_NUM2DBL, scm_dblproc):  Deprecated.
 688
 689 2000-05-10  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 690
 691         * gc.h (scm_cell, SCM_CELL_WORD, SCM_CELL_OBJECT,
 692         SCM_SET_CELL_WORD, SCM_SET_CELL_OBJECT):  Scheme cells now consist
 693         of two scm_bits_t values instead of two SCM values, because it is
 694         legal for cell entries to hold values that are not scheme objects.
 695
 696         (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR):
 697         Use SCM_SETC[AD]R to modify contents of pairs.

 701         * numbers.c (IS_INF, isfinite):  Added FIXME comment.
 702
 703         (scm_abs, scm_magnitude):  Make these two independent of each
 704         other.  scm_abs now reports an error if given a complex argument.
 705
 706         (scm_istr2flo, scm_integer_p).  Use SCM_REAL_VALUE instead of
 707         SCM_REALPART if the object is known to be real.
 708
 709         (scm_init_numbers):  No need to use SCM_NEWREAL macro for speed
 710         here.
 711
 712         * numbers.h (SCM_SINGP):  Set to 0 instead of SCM_BOOL_F.
 713
 714 2000-05-10  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 715
 716         * eq.c (scm_eqv_p):  Separate handling of real and complex
 717         values.  Remove #ifdef SCM_BIGDIG #endif test.
 718
 719         * eval.c (SCM_CEVAL, SCM_APPLY), gh_data.c (gh_scm2floats,
 720         gh_scm2doubles), hash.c (scm_hasher), ramap.c (scm_array_fill_int,
 721         ramap_rp, scm_array_map_x), random.c (vector_scale,
 722         vector_sum_squares), unif.c (scm_make_uve, scm_array_p,
 723         scm_array_set_x):  Use SCM_REAL_VALUE instead of SCM_REALPART if
 724         the object is known to be real.  Use SCM_COMPLEXP instead of
 725         deprecated SCM_CPLXP.  Use SCM_INEXACTP instead of deprecated
 726         SCM_INEXP.
 727
 728 2000-05-10  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 729
 730         * numbers.c:  No need to include unif.h.
 731
 732         (IS_INF):  Returned to old test for now:  x == x + 1 will not work
 733         for large numbers due to rounding errors.
 734         Thanks to Kalle Olavi Niemitalo.
 735
 736 2000-05-09  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 737
 738         * numbers.c (scm_divbigdig):  Removed outdated comment.
 739
 740         (scm_number_to_string, scm_string_to_number, scm_number_p,
 741         scm_real_p, scm_integer_p, scm_inexact_p, scm_gr_p, scm_leq_p,
 742         scm_geq_p, scm_make_rectangular, scm_make_polar,
 743         scm_inexact_to_exact):  Added comments.
 744
 745         (add1, scm_init_numbers):  Removed add1.
 746
 747 2000-05-09  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 748
 749         * numbers.c (IS_INF):  The new test is x == x + 1.  The old test
 750         x == x/2 did not work for zero values.  Thanks to Han-Wen Nienhuys
 751         and Ivan Toshkov.
 752
 753         (scm_number_to_string, scm_sum, scm_difference, scm_two_doubles,
 754         scm_num2long, scm_num2long_long, scm_num2ulong):  Reordered
 755         dispatch sequence.
 756
 757 2000-05-09  Marius Vollmer  <mvo@zagadka.ping.de>
 758
 759         * scmsigs.c (take_signal): Execute SCM_ASYNC_TICK for SIGSEGV,
 760         SIGILL and SIGBUS signals.  These signals are not continuable and
 761         must be handled for real right away.
 762
 763 2000-05-08  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 764
 765         * numbers.c (scm_zero_p, scm_positive_p, scm_negative_p,
 766         scm_real_part, scm_imag_part, scm_magnitude,
 767         scm_inexact_to_exact):  Reordered dispatch sequence.
 768
 769 2000-05-08  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 770
 771         * feature.c:  No need to include "libguile/smob.h"
 772
 773         (scm_loc_features, features, scm_add_feature, scm_init_feature):
 774         Removed variable 'scm_loc_features' as a pointer to the SCM value
 775         holding the features list.  Using variable 'features' instead,
 776         which holds the interned pair.  Thus, SCM_SETCDR can be used
 777         instead of pointer trickery.
 778
 779 2000-05-08  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 780
 781         * alist.c (scm_acons):  Use SCM{_SET}?_CELL_OBJECT as long as a
 782         cell is not known to be a valid pair.
 783
 784 2000-05-08  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 785
 786         * eval.c (ASRTSYNTAX, scm_m_body, scm_m_letrec1):  Removed
 787         ASRTSYNTAX.  Using SCM_ASSYNT instead.
 788
 789         (scm_m_body):  Don't create a redundant cons cell.
 790
 791         (scm_m_do):  Removed redundant test 'bodycheck'.
 792
 793         (bodycheck):  Removed.
 794
 795         * stacks.c (stack_depth, read_frame, read_frames):  Removed
 796         redundant calculation of size, minimized some variable scopes.
 797
 798 2000-05-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 799
 800         * pairs.c (scm_cons, scm_cons2):  Use SCM{_SET}?_CELL_OBJECT as
 801         long as a cell is not known to be a valid pair.
 802
 803         (scm_pair_p):  Eliminated redundant SCM_IMP test.
 804
 805 2000-05-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 806
 807         * eval.c (scm_m_body, scm_macroexp, unmemocopy, scm_eval_args,
 808         scm_deval_args):  Eliminated redundant SCM_IMP tests.
 809
 810         * hashtab.c (scm_ihashx, scm_sloppy_assx, scm_delx_x), weaks.c
 811         (scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
 812         scm_make_doubly_weak_hash_table):  Fixed critical sections.
 813         Thanks to Keisuke Nishida.
 814
 815 2000-05-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 816
 817         * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest):
 818         Fixed some goto-related initialization bugs (introduced by me).
 819
 820 2000-05-04  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 821
 822         * numbers.h (SCM_INUM0):  Uses SCM_MAKINUM instead of SCM_PACK.
 823
 824         * dynl.c (dynl_obj, DYNL_OBJ, get_dynl_obj):  Removed.
 825
 826         (DYNL_FILENAME, DYNL_HANDLE):  Use SCM_CELL... macros instead of
 827         pointer trickery.
 828
 829         (SET_DYNL_HANDLE):  Added.
 830
 831         (scm_dynamic_object_p):  Simplified.
 832
 833         (scm_dynamic_unlink, scm_dynamic_func):  Changed comment.  Deliver
 834         better error message when accessing unlinked dynamic objects.
 835         Eliminated call to get_dynl_obj.
 836
 837 2000-05-03  Marius Vollmer  <mvo@zagadka.ping.de>
 838
 839         * scmsigs.c (orig_handlers) [!HAVE_SIGACTION]: Fix declaration to
 840         be an array of function pointers instead of being a pointer to an
 841         array returning function.  Thanks to Kalle Olavi Niemitalo!
 842
 843 2000-05-03  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 844
 845         * numbers.c (scm_divbigbig, scm_divbigint), numbers.h
 846         (scm_divbigbig, scm_divbigint):  Don't return zero any more to
 847         indicate that a division has a remainder, return SCM_UNDEFINED
 848         instead.  It is improbable that anyone actually used these
 849         functions outside of numbers.c.  For this reason and due to the
 850         change in behaviour the functions are static now.  Thus, if
 851         surprisingly there are users of these functions they will at least
 852         get alarmed.
 853
 854         * numbers.c:  Removed #ifdef SCM_BIGDIG #endif in those functions,
 855         that already have a clean dispatch order.  Note: SCM_BIGDIG is
 856         always defined.
 857
 858         * numbers.c (scm_inexact_p):  Simplified.
 859
 860         * numbers.c (scm_num_eq_p, scm_less_p, scm_max, scm_min,
 861         scm_product, scm_num2dbl, scm_angle):  Reordered dispatch
 862         sequence, thereby fixing some comparisons of SCM values with
 863         integer constants.
 864
 865         * numbers.c (scm_divide):  Division by zero of inums leads to an
 866         error now.  (Formerly, an infinite number was returned.)
 867
 868         Respect the fact, that scm_divbigbig does now return SCM_UNDEFINED
 869         if a division has a remainder.
 870
 871 2000-05-02  Gary Houston  <ghouston@arglist.com>
 872
 873         * Makefile.am (INCLUDES): add ${INCLTDL} (thanks to Tim Mooney).
 874
 875 2000-05-02  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 876
 877         * numbers.c (scm_logtest, scm_division):  Reordered dispatch
 878         sequence, thereby fixing some comparisons of SCM values with
 879         integer constants.
 880
 881         * numbers.h (scm_makdbl):  Mark as deprecated at the point of
 882         declaration.
 883
 884         * eval.c (SCM_CEVAL, SCM_APPLY), gh_data.c (gh_double2scm,
 885         gh_doubles2scm), numbers.c (scm_istr2flo, scm_max, scm_min,
 886         scm_sum, scm_difference, scm_product, scm_divide, scm_sys_expt,
 887         scm_sys_atan2, scm_make_rectangular, scm_make_polar,
 888         scm_real_part, scm_imag_part, scm_magnitude, scm_angle,
 889         scm_long2num, scm_long_long2num, scm_ulong2num), ramap.c
 890         (ramap_rp, scm_array_map_x), random.c (scm_random,
 891         scm_random_uniform, scm_random_normal_vector_x, scm_random_exp),
 892         struct.c (scm_struct_ref), unif.c (scm_array_to_list):  Replace
 893         call to scm_makdbl with a call to scm_make_real or
 894         scm_make_complex, depending on whether the imaginary part is known
 895         to be zero.
 896
 897 2000-05-01  Gary Houston  <ghouston@arglist.com>
 898
 899         * scmsigs.c: fix the definition of orig_handlers for the case
 900         that HAVE_SIGACTION is not defined (thanks to
 901         Kalle Olavi Niemitalo).
 902
 903         * Makefile.am: remove include_HEADERS (was libguile.h)
 904         libguile.h: moved to top level directory.
 905
 906 2000-04-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 907
 908         * numbers.c (SCM_SWAP):  Moved to the top of the file to allow for
 909         a wider use.
 910
 911         * numbers.c (scm_modulo, scm_gcd, scm_lcm, scm_logand, scm_logior,
 912         scm_logxor):  Reordered dispatch sequence, thereby fixing some
 913         comparisons of SCM values with integer constants.
 914
 915         * number.c (scm_logtest):  Removed some redundant SCM_{N}?IMP
 916         tests.
 917
 918 2000-04-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 919
 920         * numbers.c (scm_quotient, scm_remainder):  Removed code that was
 921         conditionally compiled based on BADIVSGNS.  BADIVSGNS does not
 922         occur anywhere else throughout guile.
 923
 924         * numbers.c (scm_quotient):  Fixed parameter number in error
 925         message.
 926
 927         * numbers.c (scm_remainder):  Reordered dispatch sequence.
 928
 929 2000-04-25  Gary Houston  <ghouston@arglist.com>
 930
 931         * posix.c (scm_execlp): docstring fix (thanks to Martin
 932         Grabmueller).
 933
 934 2000-04-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 935
 936         * eval.c (undef_object):  Made into a local static variable
 937         (suggested by Jost Boekemeier).
 938
 939 2000-04-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 940
 941         * pairs.c (cxrs, scm_init_pairs):  Simplify initialization of
 942         c[ad]+r functions.
 943
 944         * procs.c (scm_init_iprocs), procs.h (scm_subr, scm_iproc,
 945         scm_dsubr, scm_init_iprocs):  Removed.
 946
 947         * procs.h (SCM_SUBRF, SCM_DSUBRF):  Access the cell words
 948         directly instead of casting a cell to a C struct.
 949
 950 2000-04-22  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 951
 952         Better modularization of GC extensions through new C level GC
 953         hooks:
 954
 955         * weaks.c (scm_weaks_prehistory): New function: Add
 956         scm_weak_vector_gc_init to scm_before_mark_c_hook; Add
 957         scm_mark_weak_vector_spines to scm_before_sweep_c_hook.
 958         (scm_scan_weak_vectors): New function; added to
 959         scm_after_sweep_c_hook.
 960
 961         * weaks.h (scm_weak_vectors, scm_weaks_prehistory): Added
 962         declarations.
 963
 964         * guardians.h (scm_guardian_gc_init, scm_guardian_zombify): Are
 965         now static.
 966
 967         * guardians.c (scm_guardian_gc_init): Turned into a hook function
 968         and added to scm_before_mark_c_hook.
 969         (scm_guardian_zombify): Turned into a hook function and added to
 970         scm_before_sweep_c_hook.
 971
 972         * async.c (scm_sys_gc_async_thunk): Run after-gc-hook.
 973         Added #include "libguile/gc.h".
 974
 975         * gc.h: Added #include "libguile/hooks.h".
 976
 977         * gc.c: Removed #include "libguile/guardians.h".
 978         (scm_before_gc_c_hook, scm_before_mark_c_hook,
 979         scm_before_sweep_c_hook, scm_after_sweep_c_hook,
 980         scm_after_gc_c_hook): New C level hooks.
 981         (scm_after_gc_hook): New Scheme level hook.
 982         (scm_gc_sweep): Moved scanning of weak vectors to weaks.c.
 983         (scm_igc): Moved initialization of scm_weak_vectors and the call
 984         to scm_guardian_gc_init to respective module.
 985         (scm_mark_weak_vector_spines): Moved to weaks.c;
 986         Call to scm_guardian_zombify moved to guardians.c;
 987         Run scm_before_gc_c_hook, scm_before_sweep_c_hook,
 988         scm_after_gc_c_hook at appropriate places.
 989         (scm_init_gc): Initialize scm_after_gc_hook.
 990
 991         * hooks.c, hooks.h (scm_make_hook_with_name): Removed deprecated
 992         function.
 993
 994         * init.c (scm_boot_guile_1): Added `scm_init_hooks'.
 995
 996         * Makefile.am: Added hooks.c, hooks.h, hooks.x.
 997
 998         * feature.c, feature.h: Broke out hook code into separate files.
 999
1000         * hooks.c, hooks.h: New files.
1001
1002         * *.*: Change includes so that they always use the "prefixes"
1003         libguile/, qt/, guile-readline/, or libltdl/.
1004         (Thanks to Tim Mooney.)
1005
1006         * Makefile.am (INCLUDES): Removed THREAD_CPPFLAGS and INCLTDL.
1007         (DEFS): Added.  automake adds -I options to DEFS, and we don't
1008         want that.
1009         Removed all -I options except for the root source directory and
1010         the root build directory.
1011
1012         * numbers.c (scm_odd_p, scm_even_p): Use SCM_WRONG_TYPE_ARG
1013         instead of SCM_ASSERT (0, ...).  (Some compilers will complain
1014         about control reaching end of function otherwise, and, besides,
1015         the new code is not less clear.)
1016
1017         * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Added
1018         calls to malloc debugging functions.
1019
1020         * init.c (scm_boot_guile_1): Added calls to debug-malloc init
1021         functions.
1022
1023         * Makefile.am: Added debug-malloc.c, debug-malloc.h,
1024         debug-malloc.x.
1025
1026         * debug-malloc.c, debug-malloc.h: New files.
1027
1028 2000-04-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1029
1030         * numbers.c (scm_exact_p, scm_odd_p, scm_even_p):  Added
1031         documentation strings.
1032
1033         * numbers.c (scm_exact_p, scm_odd_p, scm_even_p, scm_abs,
1034         scm_quotient):  Reordered dispatch sequence to first handle
1035         immediates, second handle bignums and finally handle generic
1036         functions respectively signal wrong type arguments.  Hopefully
1037         this will allow for easier separation when goops is integrated.
1038
1039 2000-04-19  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1040
1041         * gc.c (which_seg):  Use SCM2PTR to convert a non immediate SCM
1042         variable into a pointer to a heap cell.
1043
1044         * gc.c (scm_mark_locations, scm_cellp, init_heap_seg,
1045         scm_unhash_name):  Remove redundant cast to SCM_CELLPTR.
1046
1047 2000-04-19  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1048
1049         * print.c (scm_iprin1):  Don't assign zero to SCM values, use
1050         SCM_UNDEFINED instead.
1051
1052         * weaks.c (scm_make_weak_vector):  Fix assignment of zero to a
1053         vector element.  (Still to be improved)
1054
1055 2000-04-19  Dirk Herrmann  <D.Herrmann@tu-bs.de>

1398         separate loop after processing all the currently known live
1399         guardians, so as to not introduce order dependencies (thanks to
1400         Gary Houston).  note that the order problems are still there if
1401         some guardians are themselves zombies, but that's a sick case that
1402         I'm not going to worry about.
1403         also, make another outer loop to process zombified
1404         guardians (which are uncovered while marking zombies).

1548
1549         * coop.c (coop_quitting_p, coop_cond_create, coop_mutex_create,

1552         (coop_create): New thread spawning mechanism which uses a "mother

1589
1590         * eq.c (scm_eqv_p, scm_equal_p):  Don't use SCM_CAR to access the

1615         data, use SCM_{SET_}?CELL_TYPE or SCM_{SET_}?WORD_[1-3].

1622         * threads.c (scm_init_threads): Pass 0 size to scm_make_smob_type
1623         for scm_tc16_thread.  As the current COOP threads are written, GC
1624         is not supposed to manage storage for threads.
1625
1626         * error.c (scm_error): Don't try to throw an error if
1627         scm_gc_heap_lock is true.
1628
1629         * coop.c (coop_finish): New function.  Called at exit.
1630         (coop_aborthelp): Free thread structures when threads die.
1631         Finished LinuxThreads compatibility support => COOP threads now
1632         mesh with LinuxThreads.
1633
1634         * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread):

1651
1652         (SCM_SETJMPBUF):  Deprecated.  Use SCM_SET_CONTREGS instead.
1653
1654         (SCM_JMPBUF, SCM_DYNENV, SCM_THROW_VALUE, SCM_BASE, SCM_SEQ,
1655         SCM_DFRAME):  Use SCM_CONTREGS instead of SCM_CHARS to access
1656         continuation data.
1657
1658         * continuations.c (scm_make_cont), init.c (start_stack),
1659         root.c (scm_internal_cwdr):  Use SCM_SET_CONTREGS instead of
1660         SCM_SETJMPBUF.
1661
1662 2000-03-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1663
1664         * symbols.h (SCM_LENGTH, SCM_SETLENGTH):  Access the length field
1665         of strings and symbols by using SCM_{SET_}?CELL_WORD_0.
1666
1667         (SCM_CHARS, SCM_UCHARS, SCM_SETCHARS):  Use SCM_{SET_}?CELL_WORD_1
1668         to access the char * field of strings and symbols.
1669
1670 2000-03-27  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1671
1672         * gc.h (SCM_NEWCELL, SCM_NEWCELL2):  Use SCM_SET_CELL_TYPE to set
1673         the type entry of a new cell.  Added a comment about things to
1674         remember when updating the list of free cells.
1675
1676         (SCM_FREEP, SCM_MARKEDP):  Use SCM_CELL_TYPE to access the type
1677         entry of a cell.
1678
1679 2000-03-27  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1680
1681         * pairs.h (SCM_CAR, SCM_CDR, SCM_SETCAR, SCM_SETCDR):  Use
1682         SCM_CELL_OBJECT and SCM_SET_CELL_OBJECT.  This change implies that
1683         with strict type checking enabled these macros will only work if
1684         given valid SCM parameters.
1685
1686         (SCM_GCCDR):  Moved to tags.h.
1687
1688         * tags.h (SCM_GCCDR):  Moved here from pairs.h.

1702         be changed, though, since the macros are not only pair related.
1703
1704         (SCMPTR):  Deleted.
1705
1706         * gc.h (SCM2PTR, PTR2SCM, scm_cell, SCM_CELLPTR, SCM_CELL_WORD*,

1709         SCM_PTR_GT, SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC,
1710         SCM_NEWCELL, SCM_NEWCELL2, SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR,
1711         SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR):  Moved here from
1712         tags.h and pairs.h.
1713
1714 2000-03-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1715
1716         * tags.h (SCM_STRICT_TYPING):  New macro that, if defined,
1717         activates strict compile time type checking for variables of
1718         type SCM.
1719         (SCM, SCM_PACK, SCM_UNPACK):  Define according to whether
1720         SCM_STRICT_TYPING or SCM_VOIDP_TEST are defined.
1721         (SCM_EQ_P):  Defined as a macro equivalent for eq?.
1722
1723 2000-03-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1724
1725         * tags.h (SCM_POINTERS_MUNGED):  Removed.
1726
1727         * gc.c (scm_gc_sweep, init_heap_seg):  Removed use of
1728         SCM_POINTERS_MUNGED, thus fixing some illegal casts to SCM.
1729
1730 2000-03-24  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1731
1732         * pairs.h (SCM_CELL_OBJECT, SCM_CELL_OBJECT_[0-3],
1733         SCM_SET_CELL_OBJECT, SCM_SET_CELL_OBJECT_[0-3], SCM_CELL_TYPE,
1734         SCM_SET_CELL_TYPE):  Added a set of low level macros for accessing
1735         cell entries.
1736         (SCM_CELL_WORD_[0-3]): Renamed from the SCM_CELL_WORD[0-3].
1737
1738         * procs.h, procs.c:  Instead of SCM_{SET_}?CELL_WORD[12], use the
1739         newly introduced SCM_{SET_}?CELL_OBJECT_[12] macros.
1740
1741 2000-03-23  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1742
1743         * tags.h: Disabled definition of SCM_VOIDP_TEST.
1744
1745         Defining SCM as void * introduces problems which haven't been
1746         handled yet.  Developers who work with these issues can enable it
1747         in their working copies.
1748
1749         Disabling this definition exposes a set of newly introduced and
1750         older misuses of types which causes warning messages during
1751         compilation.  We'll fix this successively.
1752
1753         * gc.c (scm_mark_locations): Changed * (SCM **) X --> * (SCM *) X
1754         in order to obtain a value of type SCM.
1755         (scm_cellp): Updated with new changes to scm_mark_locations.
1756
1757         * continuations.h (SCM_SETJMPBUF): Cast second arg into SCM.
1758
1759         * continuations.c (scm_make_cont): Removed cast of size_t into
1760         long.
1761
1762         * symbols.h (SCM_SETCHARS): Cast second arg into SCM.
1763
1764 2000-03-22  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1765
1766         * numbers.h (SCM_SETNUMDIGS):  Use SCM_BIGSIZEFIELD macro for
1767         shifting, not constant.  Thanks to Dale P. Smith.
1768
1769         * numbers.c (scm_sum, scm_difference):  Don't test a SCM value
1770         for being less than zero.  Decode it to a C value first.  Again,
1771         thank you Dale.
1772
1773 2000-03-22  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1774
1775         * numbers.h, ramap.c, struct.h, vectors.h:  Don't use SCM2PTR for
1776         non scheme values.  If raw data is stored in SCM variables, it has
1777         to be accessed using SCM_UNPACK until a better solution is found.
1778
1779 2000-03-22  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1780
1781         * tags.h (SCM_ECONSP, SCM_NECONSP): More corrections of
1782         pointer-arithmetic induced by the SCM_PACK/UNPACK change.
1783
1784         * print.c (scm_iprin1): SCM_PACK/UNPACK corrections.
1785
1786         * gc.c (scm_gc_sweep): SCM_PACK/UNPACK corrections.
1787
1788         * eval.c (SCM_CEVAL, scm_unmemocar): SCM_PACK/UNPACK corrections.
1789
1790         * dynwind.c (scm_swap_bindings): SCM_PACK/UNPACK corrections.
1791
1792         * async.c, __scm.h: Removed lots of the old async click logic.  It
1793         is possible to reinsert it by defining GUILE_OLD_ASYNC_CLICK in
1794         __scm.h.  Let's try this out and dump the old code after the
1795         threads reorganization.
1796         (set-tick-rate, set-switch-rate): Conditionally removed.
1797
1798 2000-03-21  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1799
1800         * gc.c (scm_gc_mark): Bugfix 1: The recent SCM_PACK/UNPACK change
1801         made SCM values into pointers.  This turned an arithmetic
1802         computation of the address of the vcell into a pointer-arithmetic
1803         one, thereby screwing up marking of structs.
1804         Bugfix 2: Removed incompletely introduced loop variable `j' used
1805         when protecting the tail array of a struct.
1806
1807 2000-03-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1808
1809         * struct.h (SCM_STRUCT_DATA):  Don't cast SCM values to pointers.
1810
1811 2000-03-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1812
1813         * symbols.h, symbols.c (scm_strhash):  Declare the string
1814         parameter as constant, since it is not modified.
1815
1816         * symbols.c (scm_intern_obarray_soft,
1817         scm_sysintern0_no_module_lookup):  Can now pass constant strings
1818         to scm_strhash without need for casting.
1819
1820 2000-03-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1821
1822         * vectors.h (SCM_VELTS, SCM_VELTS_AS_STACKITEMS):  Don't cast SCM
1823         values to pointers.  Use SCM2PTR instead.
1824
1825 2000-03-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1826
1827         * async.c (scm_set_tick_rate, scm_set_switch_rate):  Don't unpack
1828         results of SCM_INUM.
1829
1830 2000-03-21  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
1831
1832         * init.c (scm_boot_guile_1): Renamed GUILE_GC_TRIGGER_1 -->
1833         GUILE_MIN_YIELD_1, GUILE_GC_TRIGGER_2 --> GUILE_MIN_YIELD_2.
1834         GUILE_MIN_YIELD_X now take *positive* fractions of heap size.
1835
1836         * gc.c, gc.h (SCM_MIN_YIELD_1, SCM_MIN_YIELD_2,
1837         min_yield_fraction, min_yield, adjust_min_yield): Renamed from
1838         SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2, gc_trigger_fraction,
1839         gc_trigger, adjust_gc_trigger.
1840
1841         * gc.c (alloc_some_heap): Further improvement of minimal heap size
1842         prediction.
1843         (SCM_MAX): New macro.
1844         (scm_freelist_t): New field: collected_1. Previous amount of
1845         collected cells.
1846         (gc_sweep_freelist_finish): Trigger based on two last values of
1847         freelist->collected to avoid unnecessary allocation due to
1848         temporary peaks.
1849         (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2):
1850         Adjusted to 45000 cells, 40% and 40%.  Gives quick startup
1851         without extra heap allocation.
1852
1853 2000-03-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1854
1855         * numbers.h (SCM_MAKINUM):  The parameter to SCM_MAKINUM should
1856         already be a C value.  No need to unpack it.
1857
1858         * numbers.c (scm_long_long2num):  Cast the parameter to scm_bits_t
1859         if we know it fits into an inum.
1860
1861         * ramap.c (ramap_rp):  An scm_tc7_[ui]vect object does point to a
1862         field of long values.  In contrast, SCM_VELTS accesses a field of
1863         SCM values.
1864
1865 2000-03-20  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1866
1867         * gc.c (scm_gc_stats): Inserted explanation of local_scm_mtrigger
1868         etc.
1869         (scm_gc_yield_1): New variable: Holds previous yield.  Used to
1870         make better judgements.
1871         (gc_sweep_freelist_finish): Inserted explanation of use of
1872         gc_trigger.
1873
1874         * print.h, stacks.h, options.c, options.h: Changed C++
1875         commentaries to C.
1876
1877 2000-03-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1878
1879         * tags.h (SCM2PTR, PTR2SCM):  Use SCM_PACK / SCM_UNPACK correctly.
1880
1881         * numbers.h (SCM_INUMP, SCM_MAKINUM, SCM_INUM0, SCM_COMPLEX_REAL,
1882         SCM_COMPLEX_IMAG, SCM_NUMP, SCM_BDIGITS):  Use SCM_PACK /
1883         SCM_UNPACK / SCM2PTR correctly.
1884
1885 2000-03-20  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1886
1887         * gc.c (adjust_gc_trigger): Improved documentation.
1888         (alloc_some_heap): Since gc_trigger is used against
1889         freelist->collected, this is the value which should be used to
1890         predict minimum growth.
1891
1892 2000-03-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1893
1894         * eval.h:  Fix mixup of packed/unpacked SCM values.  (Thanks
1895         Thien-Thi Nguyen for the patch.)
1896
1897 2000-03-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1898
1899         * numbers.c (scm_ash):  Fixed typing problems with the second
1900         parameter and added some documentation.  (Thanks Thien-Thi Nguyen
1901         for indicating the problem.)
1902
1903 2000-03-19  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1904
1905         * gc.c, gc.h (scm_gc_yield): New variable.
1906         (adjust_gc_trigger): Use scm_gc_yield.
1907         (alloc_some_heap): Use scm_gc_yield instead of
1908         scm_gc_cells_collected.
1909
1910         * coop-threads.c: Addd #include "root.h", #include "strings.h".
1911
1912         * debug.c: Added #include "root.h".  (Thanks to Thien-Thi Nguyen.)
1913
1914         * gc.c (scm_gc_for_newcell, adjust_gc_trigger): Improved GC
1915         trigger adjustmeant: Take yield (freed cells) for all freelists
1916         into account.
1917         (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Tuned
1918         to 50000 cell heap with 45% trigger.
1919         (scm_gc_cells_collected): Reintroduced.
1920         (SCM_HEAP_SIZE): New macro.
1921         (scm_gc_sweep): Reintroduced correct computation of
1922         scm_cells_allocated.
1923         (scm_freelist_t): Corrected commentary for field `cluster_size':
1924         Clustersize counts objects, not cells;  New member
1925         `clusters_allocated'.
1926
1927 2000-03-19  Michael Livshin  <mlivshin@bigfoot.com>
1928
1929         * *.[hc]: add Emacs magic at the end of file, to ensure GNU
1930         indentation style.
1931
1932 2000-03-19  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
1933
1934         * threads.h: Added #include "libguile/throw.h".  (Thanks to
1935         Thien-Thi Nguyen.)
1936
1937 2000-03-18  Michael Livshin  <mlivshin@bigfoot.com>
1938
1939         * tags.h: (SCM_DOUBLE_CELLP, SCM_NDOUBLE_CELLP): new macros (bad
1940         names, anyone got any better ones?)
1941
1942         * gc.h: (typedef struct scm_freelist_t) remove from here.
1943
1944         * gc.c: (CELL_UP, CELL_DN) made these macros take additional
1945         parameter (the span).
1946         (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK) new macros.
1947         (typedef struct scm_freelist_t) moved here from gc.h, it had no
1948         business being externally visible.
1949         (typedef struct scm_heap_seg_data_t) renamed from
1950         scm_heap_seg_data, to be style-compliant.
1951         (scm_mark_locations) if the possible pointer points to a
1952         double-cell, check that it's properly aligned.
1953         (init_heap_seg) align double-cells properly, work with the
1954         assumption that the segment size divides cleanly by cluster size.
1955         (round_to_cluster_size) new function.
1956         (alloc_some_heap, make_initial_segment) use round_to_cluster_size
1957         to satisfy the new init_heap_seg invariant.

2016 2000-03-17  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
2017
2018         * gc.c, gc.h: Cleanup of the change of 2000-03-15.
2019         Cluster sizes are now independent of GC trigger values.
2020         GUILE_GC_TRIGGER_n can now specify a relative trigger value:
2021         A negative integer gives fraction of total heap size in percent.
2022         (SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Default values set to -40.
2023
2024         * init.c (scm_boot_guile_1): Introduced new variable
2025         GUILE_MAX_SEGMENT_SIZE; New environment variable names:
2026         GUILE_INIT_SEGMENT_SIZE_1, GUILE_GC_TRIGGER_1,
2027         GUILE_INIT_SEGMENT_SIZE_2, GUILE_GC_TRIGGER_2
2028
2029 2000-03-16  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
2030
2031         * __scm.h (GC_FREE_SEGMENTS): Disable this until we have made
2032         freeing of segment work with the new GC scheme.  (Thanks to
2033         Michael Livshin.)  Oops, also happened to make GUILE_NEW_GC_SCHEME
2034         the default, but I'll let this change stay in CVS Guile since this
2035         code is not expected to contain serious bugs.

2039         * gc.c, gc.h (scm_map_free_list): Define also if GUILE_DEBUG is
2040         defined.
2041         (scm_free_list_length): New procedure (GUILE_DEBUG).
2042         Fixed a small but serious bug introduced by the previous change.
2043
2044         * gc.c (scm_gc_sweep): Moved variable n_objects to inner sweep
2045         loop and declare as register.
2046
2047         * gc.c (scm_gc_sweep): Sigh... forgot to clear private freelists
2048         after GC.
2049
2050 Wed Mar 15 08:27:04 2000  Greg J. Badros  <gjb@cs.washington.edu>
2051
2052         * fluids.c: Docstring patch from Keisuke Nishida.  Some
2053         reindentation, too, and a couple formals renamed.  Should
2054         fluid-set! return UNSPECIFIED instead of a value?
2055
2056 Wed Mar 15 08:24:58 2000  Greg J. Badros  <gjb@cs.washington.edu>
2057
2058         * Makefile.am: Separate out DOT_X_FILES and DOT_DOC_FILES, and
2059         generate the latter from the concrete listing of the former.  Then
2060         make guile-procedures.txt depend on DOT_DOC_FILES instead of
2061         *.doc, so that rebuilding it works.
2062
2063 Wed Mar 15 08:12:14 2000  Greg J. Badros  <gjb@cs.washington.edu>
2064
2065         * libguile.h: Include libguile/validate.h.  Thanks Keisuke Nishida!
2066
2067         * guile-snarf.awk.in: Replace docstring line-ending \n" and \n\n"
2068         with nothing and \n, respectively. Thanks Keisuke Nishida for
2069         noticing this problem.
2070
2071 2000-03-15  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
2072
2073         * __scm.h (GUILE_NEW_GC_SCHEME): Define this if you want to test a
2074         new way of allocating heap.  It makes Guile fast, but still
2075         contains bugs.
2076
2077         * gc.c, gc.h, pairs.h, init.c: Implementation of a new way of
2078         allocating heap.  The basic idea is to trigger GC every Nth
2079         allocated cell and grow heap when free list runs out.  The scheme
2080         has been extended so that GC isn't triggered until all remaining
2081         cells are used.  The implementation is also prepared for
2082         development in the direction of POSIX threads.
2083
2084         * gc.c (SCM_EXPHEAP): In order to grow by a factor of 1.5,
2085         SCM_EXPHEAP should return half of the heap size.
2086
2087 2000-03-14  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
2088
2089         The following change to init.c is only enabled if Guile was
2090         configured with --enable-guile-debug.
2091
2092         * init.c (scm_i_getenv_int): New function.
2093         (scm_boot_guile_1): Use the environment variables
2094         GUILE_INIT_HEAP_SIZE, GUILE_INIT_HEAP_SIZE2 to select heap size if
2095         they exist.  (This may be replaced by a Scheme level mechanism in
2096         the future.)
2097
2098         * objprop.c (s_scm_set_object_property_x): Use scm_assq instead of
2099         scm_assoc.  (Thanks to Keisuke Nishida.)
2100
2101 2000-03-14  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
2102
2103         * eval.c, lang.c, lang.h (scm_lisp_nil, scm_lisp_t): Renamed from
2104         scm_nil, scm_t.  (Thanks to Keisuke Nishida.)
2105
2106 2000-03-14  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
2107
2108         * init.c (scm_boot_guile_1): Use same initial segment size for
2109         1-word and 2-word segments.  Having the smaller size causes Guile
2110         to GC too often.  Obviously something needs to be done to allow
2111         for a smaller 2-word segment without this to happen.  (The amount
2112         of heap for each type should be automatically adapted to the
2113         application somehow.)
2114
2115         [Almost all of these changes should be documented in the NEWS
2116         file.]
2117
2118         * gc.h (scm_freelist_t): New type.
2119
2120         * pairs.h (SCM_NEWCELL, SCM_NEWCELL2): Use new style freelists.
2121
2122         * gc.c (SCM_INIT_HEAP_SIZE): Changed from 32768 --> 40000 so that
2123         all of Guile basics fits into one segment and there suitable room
2124         for work.
2125         (SCM_EXPHEAP): Now takes an argument.  Grow by a factor of 1.5
2126         instead of 2.
2127         (scm_freelist, scm_freelist2): Now of type scm_freelist_t.
2128         Freelists now contains information about object span, cells
2129         collected and amount of cells in heap segments belonging to the
2130         list.
2131         (scm_heap_size, scm_gc_cells_collected): Removed.
2132
2133         * init.c (scm_boot_guile_1): Make 2-word segment 8K (512 cells).
2134
2135         * Makefile.am (libguile_la_LDFLAGS): Bumped library version
2136         number.
2137
2138         * __scm.h eq.c, eval.c, gc.c, gc.h, gh_data, hash.c, numbers.c,
2139         numbers.h, objects.c, ramap.c, random.c, unif.c, unif.h: Extensive
2140         rewrite of handling of real and complex numbers.
2141         (SCM_FLOATS, SCM_SINGLES): These #ifdef conditionals have been
2142         removed along with the support for floats.  (Float vectors are
2143         still supported.)
2144
2145         * tags.h (scm_tcs_bignums): Removed.
2146         (scm_tc16_bigpos, scm_tc16_bigneg): Replaced by scm_tc16_big.
2147         Use SCM_BIGSIGN(x) to test for sign!
2148         (scm_tc16_big): The new bignum type.
2149         (SCM_REAL_PART, SCM_IMAG_PART): Removed.
2150
2151         * numbers.h (SCM_BIGSIGN): Sign moved to bit 16.
2152         (scm_makdbl): Deprecated.
2153         (SCM_NEWREAL, SCM_NEWCOMPLEX): New macros.
2154         (SCM_SINGP): Deprecated.
2155         (SCM_FLO): Removed.
2156         (SCM_INEXP, SCM_CPLXP): Deprecated.
2157         (SCM_INEXACTP, SCM_COMPLEXP): New macros.
2158         (SCM_COMPLEX_REAL, SCM_COMPLEX_IMAG): Renamed from
2159         SCM_REAL, SCM_IMAG (and now only valid for complex numbers).
2160         (SCM_REAL, SCM_IMAG): New, *deprecated*, selectors which work both
2161         for doubles and complex numbers.
2162         (SCM_REAL_VALUE): New selector for doubles.
2163         (scm_double_t, scm_complex_t): New types.
2164         (scm_dbl): Removed.
2165
2166         * numbers.c (scm_floprint, scm_floequal): Removed.
2167         (scm_print_real, scm_print_complex, scm_real_equalp,
2168         scm_complex_equalp): New functions.
2169
2170         * unif.c (scm_makflo): Removed.
2171
2172         * smob.h (SCM_SMOB_PREDICATE): New macro.
2173         (SCM_NEWSMOB2, SCM_RETURN_NEWSMOB2, SCM_NEWSMOB3,
2174         SCM_RETURN_NEWSMOB3): New macros.
2175
2176 1999-11-21  Michael Livshin  <mlivshin@bigfoot.com>
2177
2178         The following changes implement primitive support for double cells
2179         (i.e. four-word cells) and change the representation of some
2180         things to multi-cells instead of cons+malloc.  (Applied and
2181         modified by mdj.)
2182
2183         * pairs.h (SCM_NEWCELL2): double-cell variants of SCM_NEWCELL.
2184         (SCM_CELL_WORD, SCM_CELL_WORDLOC, SCM_SET_CELL_WORD): primitive
2185         multi-cell access macros (used by the ones below).
2186         (SCM_CELL_WORD[0-3], SCM_SET_CELL_WORD[0-3]): multi-cell access
2187         macros.
2188
2189         * gc.c (scm_freelist2): multi-cell freelists.
2190         (inner_map_free_list): map_free_list, parameterized on ncells.
2191         "nn cells in segment mm" was misleading for ncells > 1; changed to
2192         "objects".  still print cells too, though.
2193         (scm_map_free_list): rewritten using inner_map_free_list.
2194         (scm_check_freelist): get freelist as parameter, since now we have
2195         more than one.
2196         (scm_debug_newcell2): multi-cell variants of
2197         scm_debug_newcell.
2198         (scm_gc_for_newcell): take ncells and freelist pointer as
2199         parameters.
2200         (scm_gc_mark): add case for tc7_pws (procedures with setters are
2201         now double cells).
2202         (scm_gc_sweep): don't free the float data, since it's not malloced
2203         anymore.
2204         (init_heap_seg): didn't understand what n_new_objects stood for,
2205         so changed to n_new_cells.
2206         (make_initial_segment): new function, makes an initial segment
2207         according to given ncells.
2208         (scm_init_storage): call make_initial_segment, for ncells={1,2,3}.
2209
2210         * numbers.c (scm_makdbl): no malloc'ing needed, so the
2211         {DEFER,ALLOW}_INTS thing removed.
2212
2213         * numbers.h (struct scm_dbl): changed to represent a double cell,
2214         with the number in the second half.
2215
2216         * dynwind.c: changed the wind-guards representation to double
2217         cell.
2218
2219         * procs.c, procs.h: changed the procedure-with-setter representation
2220         to double cell.
2221
2222         * async.c, async.h: made async representation a double cell.
2223
2224         * dynl.c: made dynamic_obj representation a double cell.
2225
2226 2000-03-13  Gary Houston  <ghouston@arglist.com>
2227
2228         * ports.c (flush_void_port): renamed to flush_port_default.
2229         (end_input_void_port): renamed to end_input_default.
2230
2231         * init.c (scm_standard_stream_to_port): create a void port instead
2232         of opening /dev/null if the standard file descriptors are bad.
2233         advantages: no portability problems, doesn't waste a file descriptor,
2234         simplifies the code (thanks to Marius for the idea).
2235
2236         * vports.c (s_scm_make_soft_port): call scm_port_non_buffer.
2237
2238         * void ports: make reading from a void port give EOF instead of
2239         segv:
2240         * ports.c (s_scm_sys_make_void_port): modified docstring.
2241         (fill_input_void_port): new proc.
2242         (scm_init_ports): set up fill_input_void_port.
2243         * ports.c (scm_port_non_buffer): new proc.
2244         (scm_void_port): call scm_port_non_buffer.
2245
2246         * fports.c (scm_setvbuf): docstring: remove the fcntl documentation
2247         which was incorrectly appended.
2248
2249 2000-03-13  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
2250
2251         * guile-doc-snarf.in: Don't use absolute path for `sed'.  (Note
2252         that we can't use autoconf for this.  Autoconf itself relies on
2253         the existence of `sed' somewhere on your path.)  (Thanks to Dirk
2254         Herrman.)
2255
2256 2000-03-13  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
2257
2258         * Makefile.am (libguile_la_SOURCES): Moved iselect.c here from
2259         EXTRA_libguile_la_SOURCES.
2260
2261         * iselect.h: Always declare scm_internal_select.
2262
2263         * iselect.c (scm_internal_select): Added SCM_ASYNC_TICK at the
2264         end.  Also let scm_internal_select be a real function also when
2265         not using threads.
2266
2267         * __scm.h (SCM_TICK): Oops! Forgot to put SCM_ASYNC_TICK here...
2268
2269 2000-03-13  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
2270
2271         * __scm.h (SCM_ALLOW_INTS, SCM_REALLOW_INTS): Removed call to
2272         SCM_ASYNC_TICK.  (This is a preparation for POSIX threads support,
2273         and kind of an experiment: Will this cause problems?)
2274
2275 Sun Mar 12 13:26:30 2000  Greg J. Badros  <gjb@cs.washington.edu>
2276
2277         * Makefile.am: Added *.doc to DISTCLEANFILES.
2278
2279 2000-03-12  Gary Houston  <ghouston@arglist.com>
2280
2281         * fports.c (scm_fdes_to_port): call fcntl F_GETFL to test that
2282         the fdes is valid before doing anything else.  check that
2283         the file descriptor supports the modes required.
2284         (scm_fport_buffer_add): don't throw an error if fstat doesn't
2285         work: just use the default buffer size.
2286
2287         * throw.c: change an outdated comment about scm_internal_catch
2288         BODY: it doesn't take a jumpbuf arg.
2289
2290         * init.c (scm_standard_stream_to_port): install a handler in case
2291         scm_fdes_to_port throws an error.  don't check here whether the
2292         file descriptor is valid, since scm_fdes_to_port will do that.
2293         set the revealed count depending on whether the port got the
2294         standard file descriptor.
2295         (stream_body_data): new type.
2296         (stream_body, stream_handler): new procs.
2297
2298 2000-03-12  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
2299
2300         * stacks.c, stacks.h, struct.c, tags.h, unif.c (scm_bits_t):
2301         Renamed from SCMWORD.
2302
2303         * tags.h (SCM_NCELLP): Removed (SCMWORD).
2304
2305         * arbiters.c (SCM_ARB_LOCKED): Use SCM_UNPACK_CAR.
2306
2307         * async.c, boolean.h, debug.c, dynl.c, dynwind.c, eval.c, eval.h,
2308           feature.h, filesys.h, fluids.h, fports.c, fports.h, gc.c, gc.h,
2309           hash.c, keywords.h, macros.c, numbers.c, numbers.h, objects.c,
2310           objects.h, options.c, pairs.h, ports.c, ports.h, print.c,
2311           procs.h, ramap.c, read.c, smob.c, smob.h, srcprop.h, stacks.c,
2312           stacks.h, strports.c, struct.c, struct.h, tag.c, tags.h,
2313           throw.c, unif.c, unif.h, variable.h, vectors.h, weaks.c,
2314           weaks.h (SCM_PACK, SCM_UNPACK, SCM_UNPACK_CAR): Renamed from
2315           SCM_ASSCM, SCM_ASWORD, SCM_CARW).
2316
2317         * numbers.h (SCM_SRS, SCM_INUM): Corrected SCM_ASSCM/ASWORD fixes.
2318
2319         * alist.c, eval.c, net_db.c, posix.c, print.c, snarf.h, struct.c,
2320         tags.h: Fixed copyright notices.
2321
2322         * struct.c, coop-threads.c: SCM_ASSCM/ASWORD fixes.
2323
2324 2000-03-12  Marius Vollmer  <mvo@zagadka.ping.de>
2325
2326         * init.c (scm_standard_stream_to_port): Check whether the file
2327         descriptor is valid and substitute "/dev/null" when not.
2328
2329 2000-03-12  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
2330
2331         * coop-defs.h (struct timespec): Conditionally defined.
2332
2333         * coop.c (coop_condition_variable_timed_wait_mutex): Use ETIMEDOUT
2334         instead of ETIME.
2335
2336         * readline.c (match_paren): Bugfix: First arg to select is not
2337         number of descriptors but the number of the highest descriptor +
2338         1.
2339
2340         This is a preliminary attempt at a cleanup of the threads support
2341         code.  It moves things to better places, makes arguments more
2342         consistent with the POSIX API (which is used in GNOME's glib), and
2343         adds new functionality.
2344
2345         * readline.c (scm_init_readline): Added new arg to scm_init_mutex.
2346
2347         * coop-defs.h (scm_mutex_trylock): New macro: alias for
2348         coop_mutex_trylock.
2349         (scm_cond_init): Changed definition to
2350         coop_new_condition_variable_init.
2351
2352         * coop.c: #include <errno.h>
2353         (coop_timeout_qinsert): Moved here from iselect.c
2354         (coop_new_mutex_init, coop_new_condition_variable_init): New
2355         functions.  The strange names are temporary.  Use scm_mutex_init
2356         and scm_cond_init instead.
2357         (coop_mutex_trylock): New function.  Uses errno.h:EBUSY.  errno.h
2358         is ANSI C, but should we check for individual error codes in
2359         configure.in?
2360         (coop_condition_variable_timed_wait_mutex): New function.
2361         (coop_key_create, coop_setspecific, coop_getspecific,
2362         coop_key_delete): New functions.
2363
2364         * iselect.c (coop_timout_qinsert): Moved to coop.c
2365
2366 2000-03-11  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
2367
2368         * pairs.h (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR,
2369         SCM_SETOR_CDR): Corrected SCM_ASSCM/WORD fixes.
2370
2371         * tags.h (SCM_VOIDP_TEST): Renamed from VOIDP_TEST.
2372         Layout cleanups.
2373
2374         * objects.h (SCM_CLASS_FLAGS, SCM_OBJ_CLASS_FLAGS,
2375         SCM_SET_CLASS_INSTANCE_SIZE), struct.h (SCM_STRUCT_VTABLE_DATA),
2376         proc.h (SCM_CLOSCAR): SCM_ASSCM/WORD fixes.
2377
2378         * eval.c (scm_lookupcar1): Inserted SCM_ASWORD in expressions
2379         dealing with ilocs.

2382
2383         * numbers.c (scm_copy_big_dec, scm_copy_smaller, scm_big_ior,
2384         scm_big_xor, scm_big_and, scm_big_test): Added new lowlevel bignum
2385         logical functions from SCM.
2386
2387         (logand, logior, logxor, logtest, logbit?): Extended scheme
2388         logical functions to use bignums from SCM.
2389
2390         (lognot): Removed call to `SCM_VALIDATE_INUM' that prevented
2391         lognot from using bignums.
2392
2393 Thu Mar  9 11:33:25 2000  Greg J. Badros  <gjb@cs.washington.edu>
2394
2395         * vectors.h (SCM_VELTS_AS_STACKITEMS): Added this macro to help in
2396         eliminating some warnings.
2397
2398         * unif.c, strports.c, print.c, options.c: Fix some warnings on
2399         mis-use of SCM/long
2400
2401         * gc.c, gc.h: Added scm_return_first_int(), and added comment re:
2402         what the scm_return_first* functions do.
2403
2404 2000-03-09  Han-Wen Nienhuys  <hanwen@cs.uu.nl>, applied by Greg J. Badros, <gjb@cs.washington.edu>
2405
2406        * libguile/*.[ch]: make a distinction between SCM as a generic
2407        name for a Scheme object (now a void*), and SCM as 32 bit word for
2408        storing tags and immediates (now a long int).  Introduced
2409        SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
2410        code in the process: arbiter.c (use macros), unif.c (scm_array_p),
2411
2412 Wed Mar  8 10:15:59 2000  Greg J. Badros  <gjb@cs.washington.edu>
2413
2414         * numbers.c:  Use SCM_VALIDATE_LONG_COPY, and longs, not ints, in
2415         various logXXX primitives.  Thanks Eric Moore!
2416
2417 Tue Mar  7 08:05:22 2000  Greg J. Badros  <gjb@cs.washington.edu>
2418
2419         * run-test, remaining-docs-needed:  Added these scripts.  The
2420         second one is only temporary until the docstring additions are
2421         complete.   run-test may best live on, but is here mostly for
2422         convenience and awareness for now.
2423
2424         * hash.c: Docs, minor cleanup patch from Dirk Herrman.
2425
2426 Thu Mar  2 16:06:58 2000  Greg J. Badros  <gjb@cs.washington.edu>
2427
2428         * error.h, error.c: Added `scm_wrong_type_arg_msg' to support
2429         displaying the expected type.  Use SCM_LISTn in a couple places
2430         instead of scm_cons-ing by hand.
2431
2432         * __scm.h: Added SCM_ASSERT_TYPE macro.
2433
2434         * validate.h, scm_validate.h: Added the former, as a renamed
2435         version of the latter with SCM_ASSERT_TYPE used in
2436         SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
2437
2438         * Makefile.am: Rename scm_validate.h to validate.h.
2439
2440         * *.c, *.h: Include validate.h, not scm_validate.h (old name's
2441         prefix was superfluous).
2442
2443 Thu Mar  2 15:33:12 2000  Greg J. Badros  <gjb@cs.washington.edu>
2444
2445         * hashtab.c: Improved documentation for lots of functions.  Added
2446         handwritten docs for `hash-fold'.
2447
2448 Thu Mar  2 15:13:25 2000  Greg J. Badros  <gjb@cs.washington.edu>
2449
2450         * list.c: Added hand-written docs for `del{q,v,ete}1!'.
2451
2452 Thu Mar  2 12:38:30 2000  Greg J. Badros  <gjb@cs.washington.edu>
2453
2454         * list.c: Moved append docs to append! Thanks Dirk Hermann.  Also,
2455         added append docs from R4RS.
2456
2457         * strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
2458         Thanks Dirk Hermann!
2459
2460         * chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
2461         deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR.  Thanks Dirk Hermann!
2462
2463         * *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
2464         Drop use of SCM_P for function prototypes... assume an ANSI C
2465         compiler.  Thanks Dirk Hermann!

2467 Sat Feb 19 12:20:12 2000  Greg J. Badros  <gjb@cs.washington.edu>
2468
2469         * ports.c: Made `set-port-column!' and `set-port-line!' each
2470         return SCM_UNSPECIFIED instead of a (not-scheme-object) integer
2471         that caused a seg fault.  Also fixed `set-port-column!'s
2472         docstring.  Thanks Han-Wen Nienhuys for finding the bug!
2473
2474 Sun Feb 13 19:11:42 2000  Greg J. Badros  <gjb@cs.washington.edu>
2475
2476         * arbiters.c, eq.c, gc.c, guardians.c, list.c, ports.c, print.c,
2477         regex-posix.c, scmsigs.c, stime.c, strings.c, variable.c, stime.c,
2478         strings.c, variable.c:  Added lots of documentation, cleaned up
2479         some existing documentation.  Occasionally changed formal params
2480         to match docs.  Also folded an #ifdef into the inners of a
2481         primitive instead of having two copies of the primitive
2482         (`get-internal-real-time', from stime.c)
2483
2484 Sun Feb 13 18:12:19 2000  Greg J. Badros  <gjb@cs.washington.edu>
2485
2486         * ports.c: Added docs for primitives missing them.  Written by
2487         hand.
2488
2489 Sun Feb 13 09:40:36 2000  Greg J. Badros  <gjb@cs.washington.edu>
2490
2491         * guile-doc-snarf.in: Use ${AWK} -f guile-func-name-check, not
2492         just execing guile-func-name-check.  Thanks Michael Livshin!
2493
2494 Thu Feb 10 11:43:23 2000  Greg J. Badros  <gjb@cs.washington.edu>
2495
2496         * guile-snarf.awk.in: Tweak to work with Sun/HP awk, removed some
2497         dead code.  Patch from Michael Livshin.
2498
2499         * guile-doc-snarf.in: Tweak to work with Sun/HP sh.  Patch from
2500         Michael Livshin.
2501
2502 2000-02-09  Gary Houston  <ghouston@arglist.com>
2503
2504         * init.c (scm_init_standard_ports): when stdout is a tty, make the
2505         current-output-port unbuffered by default.  this is less confusing
2506         for interactive use.  it was line-buffered because of a
2507         performance problem with unbuffered ports, but I think it will be
2508         OK now.
2509
2510 2000-02-08  Gary Houston  <ghouston@arglist.com>
2511
2512         * __scm.h: don't define long_long or ulong_long if HAVE_LONG_LONGS
2513         is not defined.
2514
2515         * stime.c (scm_localtime, scm_mktime): if neither HAVE_TM_ZONE nor
2516         HAVE_TZNAME are defined, use an empty string instead of giving two
2517         spurious compile-time errors.
2518
2519 Tue Feb  8 13:57:46 2000  Greg J. Badros  <gjb@cs.washington.edu>
2520
2521         * ports.c: Doc patches from Richard Kim.  Pasted from MIT Scheme.
2522         Thanks Richard!
2523
2524 Mon Feb  7 09:07:31 2000  Greg J. Badros  <gjb@cs.washington.edu>
2525
2526         * macros.c: Doc patches from Richard Kim.  Pasted from scm.texi.
2527
2528 Sun Feb  6 20:26:21 2000  Greg J. Badros  <gjb@cs.washington.edu>
2529
2530         * pairs.c: Doc patches from Richard Kim.  Pasted from MIT Scheme
2531         (which is GNU GPL'd).
2532
2533 2000-01-31  Gary Houston  <ghouston@arglist.com>
2534
2535         * strings.h: don't use SCM_P.  don't include <string.h>.
2536         * error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>.
2537
2538         * strings.c (scm_string_ref): make the 2nd argument compulsory.
2539         previously it defaulted to zero for no good reason that I can see.
2540         use a local variable for SCM_INUM (k).  replace
2541         SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
2542
2543         (scm_makfromstr): cosmetic changes.
2544
2545         (scm_string): Accept only chars in the list, not strings, for
2546         conformance to R5RS (particularly for list->string, which is
2547         supposed to be the inverse of string->list.)  remove
2548         SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
2549         scm_makstr handles the cell allocation.  when reporting wrong-type
2550         arg, don't report the position as 1.
2551
2552         * posix.c (scm_init_posix): intern PIPE_BUF if it's defined.
2553
2554 2000-01-29  Gary Houston  <ghouston@arglist.com>
2555
2556         * posix.c (scm_pipe): rewrote the docstring.
2557
2558         * filesys.c (scm_select, retrieve_select_type, get_element,
2559         fill_select_type, set_element): modified so that Scheme
2560         "select" tests port buffers for the ability to provide input
2561         or accept output.  Previously only the underlying file descriptors
2562         were checked.  Rewrote the docstring.
2563
2564 Thu Jan 27 10:14:25 2000  Greg J. Badros  <gjb@cs.washington.edu>
2565
2566         * vectors.c, symbols.c, strorder.c: Documentation cut and pasted
2567         from Gregg Reynolds.  Thanks Gregg!
2568
2569 Thu Jan 27 09:59:38 2000  Greg J. Badros  <gjb@cs.washington.edu>
2570
2571         * strop.c (scm_i_index): Obfuscated commented-out SCM_DEFINE by
2572         adding "x" prefix to the line so that guile-func-name-check
2573         doesn't complain unnecessarily.
2574
2575 Wed Jan 26 17:33:52 2000  Greg J. Badros  <gjb@cs.washington.edu>
2576
2577         * throw.c: Factor out an #ifdef/#else/#endif choice more finely
2578         for maintainability.
2579
2580         * strop.c: Documentation added by Gregg A. Reynolds.   Pasted in
2581         from qdocs, RnRs.
2582
2583 Wed Jan 26 10:02:11 2000  Greg J. Badros  <gjb@cs.washington.edu>
2584
2585         * tag.c:  Added doc for `tag', but mark as deprecated since Mikael
2586         suggests removing tag.c altogether (and using a new `class-of'
2587         instead).
2588
2589         * strings.c:  Added documentation from Gregg A. Reynolds.  Edited
2590         a bit by me to use FOO instead of @var{foo} and to have the
2591         summary come before preconditions on input.  Also dropped trailing
2592         (rnrs) note.
2593
2594         * gsubr.c: Do not use SCM_DEFINE for `gsubr-apply'. Register the
2595         function with scm_make_subr_opt w/ last arg of 0 so it is not
2596         visible at the Scheme level. Mikael says that this is the right
2597         thing because the first arg to the proc is the guts of a compiled
2598         closure and shouldn't be exposed to the Scheme level.
2599
2600 Tue Jan 25 17:15:47 2000  Greg J. Badros  <gjb@cs.washington.edu>
2601
2602         * sort.c: typo in comment fixed.
2603
2604         * keywords.c: Added documentation.
2605
2606         * guardians.c: Added documentation (could be better).
2607
2608         * gc.c: Added docs for gc-set-debug-check-freelist.
2609
2610         * eq.c: Added docs for eq?, eqv? equal? abridged from R4RS.
2611
2612         * boolean.c: Added docs for `not', `boolean?' (by hand).
2613
2614 Tue Jan 25 13:28:56 2000  Greg J. Badros  <gjb@cs.washington.edu>
2615

2618
2619 Mon Jan 24 17:50:20 2000  Greg J. Badros  <gjb@cs.washington.edu>
2620
2621         * variable.c, version.c:  Added documentation, written by hand
2622         since I could not find anything already written that was
2623         relevant.
2624
2625 2000-01-23  Gary Houston  <ghouston@arglist.com>
2626
2627         * filesys.c (scm_chown): omit port/fdes support if HAVE_FCHOWN is
2628         not defined (thanks to Richard Y. Kim).
2629
2630 Thu Jan 20 13:00:38 2000  Greg J. Badros  <gjb@cs.washington.edu>
2631
2632         * Makefile.in: Removed, this is auto-generated.
2633
2634 Thu Jan 20 11:33:47 2000  Dirk Hermann <dirk@ida.ing.tu-bs.de> --applied 01/20/00 gjb
2635
2636         * list.c: Put some variable initialization code at the point of
2637         declaration; Added a comment for list*; Formatting changes.
2638
2639         * load.c: use SCM_NNULLP to make sure the end of a list is not
2640         reached yet.
2641
2642 2000-01-18  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
2643
2644         * backtrace.c (scm_display_error_message): Bugfix: Don't use
2645         result of scm_list_p as C boolean.
2646         (scm_display_error_message, scm_set_print_params_x): Use new
2647         validation macros. (Thanks to Dirk Herrmann.)
2648
2649         * net_db.c (scm_resolv_error): Cast result from hstrerror.
2650
2651         * strports.c (st_end_input): Inserted parenthesis to get operator
2652         grouping correct.
2653
2654         * list.h (scm_init_list): Removed SCM_P around prototypes.
2655
2656         * fports.c, list.c, numbers.c, ports.c, stime.c, symbols.c,
2657         filesys.c, posix.c: Converted docstrings to ANSI C format and
2658         escaped " occurring inside string literals.

2679 Mon Jan 17 11:41:22 2000  Greg J. Badros  <gjb@cs.washington.edu>
2680
2681         * scm_validate.h: Added SCM_VALIDATE_ULONG_COPY,
2682         SCM_VALIDATE_LONG_COPY
2683
2684         * numbers.c: Use SCM_VALIDATE_ULONG_COPY, instead of
2685         SCM_VALIDATE_INUM_COPY to let bigger numbers be used.  Rename a
2686         couple of formal arguments (and fix their uses) to make arguments
2687         match the documentation.
2688
2689 2000-01-14    <mstachow@alum.mit.edu>
2690
2691         * Makefile.am: Augment path when running guile-doc-snarf so
2692         guile-func-name-check is found.
2693
2694 Fri Jan 14 09:34:55 2000  Greg J. Badros  <gjb@cs.washington.edu>
2695
2696         * scm_validate.h (SCM_NUM2LONG_DEF): Fix this macro to just use
2697         def, not SCM_MAKINUM(def);  thanks Janis Bzerins!
2698
2699 Wed Jan 12 00:06:53 2000  Greg J. Badros  <gjb@cs.washington.edu>
2700
2701         * net_db.c (s_scm_inet_makeaddr): Use SCM_NUM2ULONG since that's
2702         the way guile-1.3.4 worked, but #if 0 out the version using
2703         SCM_VALIDATE_INUM_COPY for stricter testing.
2704
2705 Tue Jan 11 18:24:18 2000  Greg J. Badros  <gjb@cs.washington.edu>
2706
2707         * guile-doc-snarf.in: Use new $fullfilename for running
2708         guile-func-name-check, and put "$fullfilename" and "$filename" in
2709         quotes at uses to make sure re-splitting on whitespace does not
2710         occur (so filenames w/ embedded whitespace would work okay, though
2711         I sure hope we never have to deal with that! :-) ).  Thanks to
2712         Mikael for pointing out the source_dir != build_dir was broken.

2714 Tue Jan 11 17:42:40 2000  Greg J. Badros  <gjb@cs.washington.edu>
2715
2716         * scm_validate.h: Added SCM_NUM2LONG_DEF macro.  Make
2717         SCM_OUT_OF_RANGE use SCM_MAKINUM, not scm_long2num.  Added
2718         SCM_COERCE_ROSTRING macro.  Added SCM_VALIDATE_NONEMPTYLIST
2719         macro.  Fix SCM_VALIDATE_STRINGORSUBSTR macro to not use SLOPPY
2720         variants.
2721
2722         * ports.c (scm_port_closed_p): Validate that the arg is a PORT,
2723         then return whether it's an open port (was validating that it was
2724         an open port -- this was a bug I introduced back in December, but
2725         my careful reading of diffs caught it).
2726
2727         * numbers.c: Recombine the two conditional-compilation paths for
2728         all the log* primitives -- they were split based on #ifndef
2729         scm_long2num;  factored out a SCM_LOGOP_RETURN macro, and fixed
2730         some bugs and inconsistencies in the two sets of implementations.
2731         (scm_lognot) Fixed *atrocious* re-use of a SCM as an integer!
2732
2733         * ioext.c: Use SCM_ASSERT_RANGE in a couple places, and
2734         SCM_VALIDATE_INUM_COPY once where it should've been used.
2735
2736         * fluids.c (scm_internal_with_fluids): Use
2737         SCM_VALIDATE_LIST_COPYLEN.
2738
2739         * filesys.c: Use SCM_NUM2LONG instead of SCM_VALIDATE_INUM_COPY;
2740         this is questionable as it relaxes type safety, but other changes
2741         were useful and all SCM_NUM2LONG's should probably be
2742         revisited. Use SCM_OUT_OF_RANGE, SCM_WRONG_TYPE_ARG.
2743
2744         * evalext.c: line-break change on 1 line.
2745
2746         * eval.c (nconc2last): Takes a non-empty list as its first
2747         argument, not just a list.
2748
2749         * dynl.c: Use new SCM_COERCE_ROSTRING macro.
2750
2751 Tue Jan 11 15:44:23 2000  Greg J. Badros  <gjb@cs.washington.edu>
2752
2753         * dynl.c, feature.c, filesys.c, fports.c, list.c, load.c,
2754         net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
2755         where possible.
2756
2757         * symbols.c (scm_sysintern0): Fixed the function name in a
2758         scm_misc_error invocation.
2759
2760         * print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
2761         use scm_return_first to ward off latent GC bug that Mikael caught.
2762
2763         * async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
2764         used before but should've been.
2765
2766 2000-01-12  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
2767
2768         * snarf.h (SCM_PROC1): Replaced SCM (*) (...) with
2769         SCM_FUNC_CAST_ARBITRARY_ARGS.
2770
2771 Tue Jan 11 13:44:07 2000  Greg J. Badros  <gjb@cs.washington.edu>
2772
2773         * guile-func-name-check.in: Added this script to statically check
2774         #define FUNC_NAME, #undef FUNC_NAME in the source.
2775
2776         * sort.c, posix.c: Fix #undef FUNC_NAME lines to not have trailing
2777         redundant comment, semicolon; caught by new guile-func-name-check
2778         script.
2779
2780         * debug.c: Fix mistaken #define FUNC_NAME for scm_make_iloc.
2781         Caught by new guile-func-name-check-script.
2782
2783         * Makefile.am: Added guile-func-name-check to bin_SCRIPTS
2784
2785         * ramap.c: Fix #if 0'd out code to be syntactically acceptable to
2786         guile-func-name-check.
2787
2788         * guile-doc-snarf.in: Run guile-func-name-check on the file before
2789         doing the snarf.
2790
2791 Tue Jan 11 11:31:10 2000  Greg J. Badros  <gjb@cs.washington.edu>
2792
2793         * fports.c, ports.c, ports.h, strports.c, vports.c: Make write
2794         port function take const void*, not void*.
2795
2796 Tue Jan 11 11:18:07 2000  Greg J. Badros  <gjb@cs.washington.edu>
2797
2798         * scm_validate.h, chars.c, ports.c, print.c, read.c, strings.c,
2799         strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
2800         SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY.  Change made for
2801         consistency with the other macros dealing with immediate
2802         characters.  (Similar to INT -> INUM change a week or so ago).
2803
2804 Tue Jan 11 10:41:46 2000  Greg J. Badros  <gjb@cs.washington.edu>
2805
2806         * dynl.c, error.c, eval.c, feature.c, filesys.c, fports.c, list.c, load.c,
2807         net_db.c, read.c, socket.c: Update error messages to use ~A for
2808         %s, ~S for %S to work with new `simple-format' format and be
2809         standardized better.
2810
2811         * print.h, print.c (scm_simple_format): Added `simple-format'
2812         primitive.  It's the old scm_display_error, with ARGS now a rest
2813         parameter, and the destination first instead of last (and a couple
2814         new capabilities inspired by `format' -- #t as destination means
2815         current-output-port, #f means return the formatted text as a
2816         string.
2817
2818         * gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
2819
2820         * backtrace.c (scm_display_error_message): Rewrote to use
2821         scm_simple_format() procedure.
2822
2823         * __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
2824
2825 2000-01-09  Marius Vollmer  <mvo@zagadka.ping.de>
2826
2827         Finally applied the libltdl patch from Thomas Tanner, with slight
2828         modifications.
2829
2830         * DYNAMIC-LINKING: Removed because it is obsolete.
2831         * dynl.c: Use ANSI prototypes.
2832         (sysdep_dynl_link): Use lt_dlopenext instead of lt_dlopen.
2833         * scmconfig.h.in: Do not change, as it is automatically generated.
2834
2835     1999-07-25  Thomas Tanner  <tanner@ffii.org>
2836
2837             * dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c: deleted
2838             (obsolete)
2839             * Makefile.am: likewise, add INCLTDL (libltdl headers) to
2840             INCLUDES, set dlpreopened files in LDFLAGS, link libguile
2841             against libltdl
2842             * dynl.c: use libltdl if DYNAMIC_LINKING is enabled,
2843             * guile.c: register preloaded modules
2844             * scmconfig.h.in: remove obsolete symbols
2845
2846 2000-01-09  Gary Houston  <ghouston@arglist.com>
2847
2848         * These changes should make it unnecessary to call tzset from
2849         Scheme after modifying the TZ environment variable, even if the
2850         system date facilities cache the value.
2851         * stime.c (setzone, scm_localtime): added comments.
2852         (tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
2853         (setzone): don't call tzset.
2854         (restorezone): call tzset only if HAVE_TZSET is defined.
2855         (scm_tzset): don't define if HAVE_TZSET not defined.  Change the
2856         doc string to indicate that this procedure isn't likely to do
2857         anything useful.
2858         (scm_localtime, scm_strftime, scm_mktime): call tzset if
2859         LOCALTIME_CACHE is defined.
2860
2861 2000-01-09  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
2862
2863         * posix.c (scm_sync): Return SCM_UNSPECIFIED.
2864
2865 2000-01-09  Gary Houston  <ghouston@arglist.com>
2866
2867         * eval.c: define scm_unbound_variable_key ('unbound-variable).
2868         scm_lookupcar1: throw an error with key 'unbound-variable instead
2869         of 'misc-error when an unbound variable is encountered.
2870
2871         * filesys.c (scm_mkdir, scm_rmdir, scm_getcwd, scm_select,
2872         scm_symlink, scm_readlink, scm_lstat),
2873         posix.c (scm_setpgid, scm_setsid, scm_ctermid, scm_tcgetpgrp,
2874         scm_tcsetpgrp, scm_uname, scm_setlocale, scm_mknod, scm_nice,
2875         scm_sync),
2876         simpos.c (scm_system),
2877         stime.c (scm_times, scm_strptime):
2878         move the HAVE_XXX feature tests out of the procedure bodies.
2879         don't use SCM_SYSMISSING.
2880         scm_validate.h (SCM_SYSMISSING): removed.
2881         error.h, error.c (scm_sysmissing): comment that this is deprecated.
2882         see ChangeLog entry for 1999-12-28.
2883
2884 Sat Jan  8 19:52:04 2000  Greg J. Badros  <gjb@cs.washington.edu>
2885
2886         * scm_validate.h (SCM_VALIDATE_BOOL_COPY): Fix typo.
2887
2888 Sat Jan  8 17:06:46 2000  Greg J. Badros  <gjb@cs.washington.edu>
2889
2890         * backtrace.c: Fix spelling typo in a comment.
2891
2892         * snarf.h: Use new SCM_DOCS macro to encapsulate the non SCM_INIT
2893         text.  Reformatted some of the expansions.
2894
2895 Fri Jan  7 15:50:46 2000  Greg J. Badros  <gjb@cs.washington.edu>
2896
2897         * scm_validate.h (SCM_OUT_OF_RANGE): Use scm_out_of_range_pos to
2898         report the position of the argument.
2899
2900         * error.h, error.c (scm_out_of_range_pos):  Added this function to
2901         take extra "pos" argument, the position number of the errant
2902         argument.
2903
2904         * debug.c: Use SCM_OUT_OF_RANGE instead of scm_out_of_range.
2905
2906         * snarf.h: Use SCM_HERE and SCM_INIT as names, not SCM_NOTSNARF
2907         and SCM_SNARFING.  Also put the %%% in the SCM_INIT since Mikael
2908         prefers that and I'm reasonably indifferent.
2909
2910 Fri Jan  7 15:03:32 2000  Greg J. Badros  <gjb@cs.washington.edu>
2911
2912         * snarf.h: Factor out differences between C++ and non-C++ into
2913         SCM_FUNC_CAST_ARBITRARY_ARGS macro.  Modify all the snarf macro
2914         definitions to use SCM_NOTSNARF and SCM_SNARFING macros (like
2915         Mikael's macros, below, but changed names and SCM_SNARFING no
2916         longer expands to include %%% -- that must appear in the argument
2917         so that the token appears at the call-site as a reminder).
2918
2919 2000-01-07  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
2920
2921         * snarf.h (SCM_INSITU, SCM_INIT): New snarf macros for use in user
2922         snarf macro definitions.
2923
2924 2000-01-06  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
2925
2926         * chars.c (scm_integer_to_char): Use Greg's nice
2927         SCM_VALIDATE_INUM_RANGE macro for argument checking for closer
2928         adherence to R5RS.
2929
2930 Thu Jan  6 11:48:49 2000  Greg J. Badros  <gjb@cs.washington.edu>
2931
2932         * *.c, snarf.h: Replace GUILE_PROC1 with SCM_DEFINE1 throughout.
2933
2934 Thu Jan  6 11:22:53 2000  Greg J. Badros  <gjb@cs.washington.edu>
2935
2936         * Makefile.am (ETAGS_ARGS): Switch to SCM_DEFINE, SCM_DEFINE1
2937         instead of GUILE_PROC.
2938
2939 Thu Jan  6 11:21:49 2000  Greg J. Badros  <gjb@cs.washington.edu>
2940
2941         * alist.c: Do not report mismatch errors on some uses of `tmp' (do
2942         this by using SCM_ARG2 instead of `2' in the SCM_VALIDATE_CONS
2943         macro call.
2944
2945 Thu Jan  6 09:54:33 2000  Dirk Herrmann <dirk@ida.ing.tu-bs.de> --gjb applied
2946
2947         * scm_validate.h: Remove some redundant NIMP tests.
2948
2949         * alist.c: minimize scope of the tmp variables, and initialize
2950         them when declared. The strange SCM_NIMP tests are replaced by
2951         SCM_CONSP tests that more closely reflect the intended semantics.
2952         However, we don't get a performance penalty here, because the
2953         SCM_CONSP test was performed by the ALISTCELL test anyway.  * The
2954         extremely ugly use of ASRTGO macros was removed: The calls to
2955         ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a
2956         label parameter that only exists when SCM_RECKLESS is not defined.
2957         This works, because ASRTGO itself is defined in a way that it only
2958         makes use of the label parameter if SCM_RECKLESS is not defined
2959         (shudder!).  Does guile make at all use of the possibility to
2960         define SCM_RECKLESS?  * Codesize is likely to be reduced, since
2961         instead of two calls to SCM_ASSERT performed by the ALISTCELL test
2962         we now only get one test.
2963
2964         * list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate.  Also use
2965         SCM_NULLP instead of SCM_IMP.  Drop use of "register" keyword on
2966         some variables in `list?'.  Fix `reverse' and `reverse!'
2967         primitives to handle improper lists better.
2968
2969 Wed Jan  5 11:24:53 2000  Greg J. Badros  <gjb@cs.washington.edu>
2970
2971         * *.[ch]: Whitespace changes -- added space after SCM_VALIDATE_*
2972         macros and SCM_DEFINE macros to match GNU coding standards.
2973
2974 Wed Jan  5 11:04:24 2000  Greg J. Badros  <gjb@cs.washington.edu>
2975
2976         * *.[ch]: Replace GUILE_PROC w/ SCM_DEFINE.
2977
2978 Wed Jan  5 10:59:06 2000  Greg J. Badros  <gjb@cs.washington.edu>
2979
2980         * *.[ch]:  Replace SCM_VALIDATE_INT w/ SCM_VALIDATE_INUM for
2981         better consistency with the names of other SCM_VALIDATE_ macros
2982         and better conformance to guile naming policy.
2983
2984 Wed Jan  5 10:50:39 2000  Greg J. Badros  <gjb@cs.washington.edu>
2985
2986         * ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a
2987         SCM_VALIDATE instead of 1 to avoid a check on the argument (since
2988         it's not the actual name of the formal).
2989
2990         * guile-snarf.awk.in: Do argument/number mismatch checking and
2991         print warnings in an Emacs compile-mode parseable format.
2992
2993         * struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/
2994         SCM_OUTOFRANGE as 3rd argument.
2995
2996         * random.c: Fix argument/number mismatch (that I introduced :-( ).
2997
2998         * __scm.h: Do not #define SCM_ARG* when snarfing;
2999         lets us distinguish between 1 and SCM_ARG1 when snarfing as only
3000         the former (using the number) requires the argument to match the
3001         formal in the current argument snarfing check.
3002
3003         * snarf.h: Give new definition of SCM_ASSERT when in
3004         snarfing mode to output a lexically-identifiable sequence that the
3005         guile-snarf.awk script uses to verify argument/position matching.
3006
3007         * ramap.c: Remove extraneous #undef FUNC_NAME.
3008
3009 Wed Jan  5 08:36:38 2000  Greg J. Badros  <gjb@cs.washington.edu>
3010
3011         * guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the
3012         current version of the same functionality; it writes the .x output
3013         to stdout instead of directly into the file.
3014
3015 Wed Jan  5 08:15:04 2000  Greg J. Badros  <gjb@cs.washington.edu>
3016
3017         * unif.c, symbols.c, strings.c, stacks.c, random.c, print.c,
3018         posix.c:  Eliminated a bunch of SCM_NIMP(..)s that are now
3019         redundant with the safer macros.  Patch from Dirk Hermann applied
3020         by hand. Thanks Dirk!
3021
3022         * scm_validate.h: Added SCM_VALIDATE_VECTOR_OR_DVECTOR for some
3023         uses in random.c.
3024
3025         * ramap.c: whitespace change.
3026
3027 Tue Jan  4 14:21:35 2000  Greg J. Badros  <gjb@cs.washington.edu>
3028
3029         * options.c, objects.c, keywords.c, gc.c: Some redundant SCM_NIMP
3030         removals from Dirk Hermann.
3031
3032         * alist.c: Rename formals to match the parameter names in the
3033         documentation, updates to documentation.  Thanks Dirk Hermann!
3034
3035 2000-01-04  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
