libguile/ChangeLog

   1 2000-06-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>
   2
   3         * guile-snarf.awk.in, guile-snarf.in, snarf.h:  Rename SCM__I to
   4         SCM_SNARF_INIT_START, SCM__D to SCM_SNARF_DOC_START, SCM__S to
   5         SCM_SNARF_DOCSTRING_START and SCM__E to SCM_SNARF_DOCSTRING_END.
   6
   7 2000-06-21  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
   8
   9         * eval.c, eval.h (scm_top_level_lookup_closure_var): Added.
  10         #include "libguile/fluids.h".
  11
  12         * eval.h (SCM_TOP_LEVEL_LOOKUP_CLOSURE): New macro which replaces
  13         SCM_CDR (scm_top_level_lookup_closure_var) everywhere.
  14
  15         * root.h (scm_top_level_lookup_closure_var,
  16         scm_system_transformer): Removed.  (It's no sense in having the
  17         *variable* be a "fluid".)
  18
  19         * root.c (mark_root): Removed marking of
  20         s->top_level_lookup_closure_var and s->system_transformer.
  21
  22         * modules.c (scm_selected_module): the_module is now a fluid.
  23
  24 2000-06-20  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
  25
  26         * gc.h, tags.h: Be kind to compilers which must see hash signs in
  27         column 0.  (Thanks to Ian Grant.)
  28
  29         * numbers.h: Put #ifdef HAVE_LONG_LONGS around declarations using
  30         the long_long type.  (Thanks to Bernard Urban.)
  31
  32 2000-06-20  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
  33
  34         * gc.c, gc.h (scm_default_init_heap_size_1,
  35         scm_default_min_yield_1, scm_default_init_heap_size_2,
  36         scm_default_min_yield_2, scm_default_max_segment_size): New global
  37         variables.  Can be customized by the application before booting
  38         Guile.  (We might want to be able to control these parameters
  39         dynamically through the "options interface" in the future, but
  40         note that that is additional functionality.  Here we're giving
  41         default values which the environment variables can override.)
  42
  43         * list.c (scm_cons_star): Updated comment.
  44
  45         * smob.h: Changed comments for scm_make_smob_type and
  46         scm_make_smob_type_mfpe, warning that the latter might be
  47         deprecated in a future release.
  48
  49 2000-06-19  Dirk Herrmann  <D.Herrmann@tu-bs.de>
  50
  51         * list.[ch] (scm_cons_star/cons*):  Renamed from
  52         scm_list_star/list*.
  53
  54         * list.[ch] (scm_list_star/list*):  Provided as a deprecated alias
  55         for scm_cons_star/cons*.
  56
  57         * gc.c (scm_protect_object):  Updated comment.
  58
  59         * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX):  Removed.
  60
  61         * tags.h (SCM_UNPACK_CAR, SCM_NDOUBLE_CELLP):  Removed.
  62
  63 2000-06-19  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
  64
  65         * init.c, init.h (scm_initialized_p): Renamed from `initialized'
  66         and made global.
  67
  68         * gdbint.c (gdb_print): Print warning instead of calling scm_write
  69         if Guile isn't yet initialized.
  70
  71         * print.c (scm_current_pstate, scm_make_print_state): Simplified
  72         tests, using the assumption that Guile has been initialized.
  73
  74 Sun Jun 18 14:45:21 2000  Greg J. Badros  <gjb@cs.washington.edu>
  75
  76         * print.c (s_scm_current_pstate): Do not segfault when the
  77         print_state_pool is unitialized in `current-pstate', and better
  78         verify its state before altering it in scm_make_print_state().
  79
  80 2000-06-18  Michael Livshin  <mlivshin@bigfoot.com>
  81
  82         * scmsigs.c (s_scm_sigaction): guard the SIGIOT case with an
  83         #ifdef -- it's missing on at least one platform.  (thanks to
  84         Jan Nieuwenhuizen).
  85
  86 2000-06-16  Dirk Herrmann  <D.Herrmann@tu-bs.de>
  87
  88         * list.c (list*):  Added documentation from common-list.scm.
  89
  90 2000-06-15  Dirk Herrmann  <D.Herrmann@tu-bs.de>
  91
  92         * gc.c (scm_unprotect_object):  The reference count is guaranteed
  93         to be a positive number.
  94
  95 2000-06-15  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
  96
  97         * eval.c: Updated comment above scm_map.
  98
  99 2000-06-14  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 100
 101         * gc.c (scm_protect_object): Avoid looking up the object handle
 102         twice.
 103         (scm_unprotect_object): Abort if scm_unprotect_object is called on
 104         an unprotected object.
 105
 106 2000-06-14  Michael Livshin  <mlivshin@bigfoot.com>
 107
 108         * gc.c (scm_unprotect_object): fix a nasty typo bug (thanks to
 109         Dirk Herrmann).
 110
 111 2000-06-14  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 112
 113         * socket.c (scm_getsockopt): Changed type for `optlen' from int to
 114         size_t.
 115         (scm_accept, scm_getsockname, scm_getpeername, scm_recvfrom):
 116         Ditto for `tmp_size'.
 117         (scm_addr_buffer_size): Changed type from int to size_t.
 118
 119         * random.c: #include <string.h>.  (Needed by memcpy.)
 120
 121         * guile-snarf.awk.in: Replace the dot_doc_file arg with "-",
 122         indicating stdin, instead of "" and don't reset ARGC.  This is a
 123         workaround for `nawk' in AIX 4.3 on RS6000 but, as far as I know,
 124         it is correct, and perhaps even better.
 125
 126 2000-06-14  Gary Houston  <ghouston@arglist.com>
 127
 128         * scmsigs.c (scm_init_scmsigs): if HAVE_SIGINTERRUPT is not
 129         defined, add SA_RESTART to the sigaction flags correctly
 130         (thanks to Dale P. Smith).
 131
 132 2000-06-13  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 133
 134         * strings.c: #include <string.h>. (Thanks to Bill Schottstaedt.)
 135
 136         * net_db.c (scm_resolv_error): Only use macro NETDB_INTERNAL if
 137         defined. It isn't on sgi irix 5.3.  (Thanks to Bill Schottstaedt.)
 138
 139         * Makefile.am (.c.doc): Pipe output (the .x contents) to /dev/null.
 140
 141 2000-06-13  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 142
 143         * fports.c (scm_setvbuf): Use `free' instead of `scm_must_free'
 144         since read and write buffers are allocated by `malloc'.
 145
 146         * Makefile.am: Removed old test code.
 147
 148         * gh_test_c.c, gh_test_repl.c: Removed.
 149
 150 2000-06-12  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 151
 152         * iselect.c (SCM_NLONGBITS): Add workaround for the Sun 4.2
 153         compiler.
 154
 155         * inet_aton.c (inet_aton): Cast init value for `cp'.
 156
 157         * ramap.c (s_scm_array_fill_x): Cast `ve' properly in case
 158         `scm_tc7_uvect'.
 159
 160         * symbols.c (scm_intern_obarray_soft,
 161         scm_sysintern0_no_module_lookup): Cast `name' to unsigned char ptr
 162         in calls to scm_strhash.
 163
 164         * strports.c (st_resize_port): Substituted SCM_UCHARS for
 165         SCM_CHARS.
 166         (st_write): Cast argument to strncpy to char ptr.
 167         (scm_mkstrport): Substituted SCM_ROUCHARS for SCM_ROCHARS.
 168         (scm_strport_to_string): Cast argument to scm_makfromstr to char
 169         ptr.
 170
 171         * ports.c (scm_ungetc): Cast value to unsigned char ptr before
 172         storing in putback_buf.
 173         (scm_unread_string): Substituted SCM_ROCHARS for SCM_ROUCHARS.
 174
 175         * ioext.c (s_scm_read_line): Cast result of call to
 176         scm_do_read_line to unsigned char ptr.
 177
 178         * gdbint.c (SEND_STRING): Cast argument to char pointer.
 179
 180         * fports.c (fport_flush): Declare `ptr' as unsigned char (was
 181         char).
 182
 183         * Makefile.am (DOT_DOC_FILES): List doc-files explicitly.  (We
 184         shouldn't use Make rules which aren't supported by most Make
 185         programs.)
 186         (OMIT_DEPENDENCIES): Defined to "libguile.h ltdl.h".  (We don't
 187         want these dependencies recorded, since they would get bogus
 188         relative paths; libguile.h is only used in gh.h and guile.c.)
 189         (EXTRA_DOT_X_FILES, EXTRA_DOT_DOC_FILES): New variables.
 190         (guile-procedures.txt): Depend on EXTRA_DOT_DOC_FILES.
 191         (modinclude_HEADERS): Removed kw.h.
 192
 193         * guile-snarf.in: Change regexp "^SCM__I" --> "^ *SCM__I".
 194         (The preprocessor might insert spaces before the identifier.)
 195
 196         * snarf.h (SCM_SNARF_HERE, SCM_SNARF_INIT, SCM_SNARF_DOCS):
 197         Renamed from SCM_HERE, SCM_INIT, SCM_DOCS.
 198
 199         * smob.h (scm_smobfuns): Removed deprecated type.
 200
 201         * smob.c, smob.h (scm_newsmob): Removed deprecated function.
 202         (Replaced by `scm_make_smob_type'.)
 203
 204         * keywords.c (scm_tc16_kw): Removed deprecated type.
 205         (Replaced by scm_tc16_keyword.)
 206
 207         * kw.h: Removed deprecated header file.
 208
 209         * evalext.c (serial-map): Removed deprected alias for scm_map.
 210         (Has been replaced by `map-in-order'.)
 211
 212         * ramap.c (serial-array-copy!, serial-array-map!): Removed
 213         depracted aliases.  (Replaced by `array-copy-in-order!' and
 214         `array-map-in-order'.)
 215
 216 2000-06-11  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 217
 218         * gc.h (SCM_VALIDATE_CELL): Rewritten.
 219         (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
 220         SCM_SET_CELL_OBJECT): Use new version of SCM_VALIDATE_CELL.
 221         (Thanks to Han-Wen Nienhuys.)
 222
 223 2000-06-10  Michael Livshin  <mlivshin@bigfoot.com>
 224
 225         * guile-doc-snarf.in: don't pipe the CPP output right into sed --
 226         write it to the temp file first and check the CPP return code.
 227         (I introduced this bug earlier, and this probably caused people
 228         with non-GNU C preprocessors to get empty *.x files and not to
 229         have the build fail right away...).
 230
 231         * scmsigs.c (s_scm_sigaction): guard the SIGSYS case with an ifdef
 232         -- at least my libc5-based Linux system doesn't define SIGSYS.
 233
 234 2000-06-08  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 235
 236         * snarf.h, guile-snarf.awk.in, guile-snarf.in: Replaced snarf
 237         markers with identifiers (SCM__I, SCM__D, SCM__S, SCM__E).
 238         (Thanks to Bernard Urban.)
 239
 240 2000-06-06  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 241
 242         * modules.c (scm_system_module_env_p): Fixed detection of system
 243         modules.
 244
 245 2000-06-06  Marius Vollmer  <mvo@zagadka.ping.de>
 246
 247         * scmsigs.c (scm_sigaction): Silently ignore setting handlers for
 248         `program error signals' because they can't currently be handled by
 249         Scheme code.
 250
 251 2000-06-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 252
 253         * procs.h (SCM_SET_SUBRF):  Added.
 254
 255         * procs.c (scm_make_subr_opt):  Don't assign to SCM_SUBRF, use
 256         SCM_SET_SUBRF instead.  Thanks to Bernard Urban for the bug
 257         report.
 258
 259 2000-06-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 260
 261         * gc.h (SCM_CARLOC, SCM_CDRLOC):  Don't take the address of a SCM
 262         value.
 263
 264         * sort.c (scm_sorted_p, scm_merge, scm_merge_list_x,
 265         scm_merge_list_step):  Don't take the address of SCM_CAR.  Use
 266         SCM_CARLOC instead.  Thanks to Bernard Urban for the bug report.
 267
 268 2000-06-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 269
 270         * boolean.h (SCM_TRUE_P):  Removed, as people might use it as a
 271         replacement for !SCM_FALSEP.
 272
 273         * backtrace.c (display_error_body), boolean.h (SCM_BOOLP), gc.c
 274         (scm_unhash_name), gh_data.c (gh_module_lookup), load.c
 275         (scm_primitive_load), print.c (scm_simple_format), procs.c
 276         (scm_procedure_documentation), procs.h (SCM_TOP_LEVEL), ramap.c
 277         (scm_array_fill_int), scmsigs.c (scm_sigaction), stacks.c
 278         (narrow_stack, scm_make_stack, scm_stack_id), symbols.c
 279         (scm_string_to_obarray_symbol), throw.c (scm_catch,
 280         scm_lazy_catch, scm_ithrow), unif.c (scm_make_uve, scm_array_p,
 281         scm_array_set_x, scm_bit_set_star_x, scm_bit_count_star),
 282         validate.h (SCM_VALIDATE_BOOL_COPY, SCM_VALIDATE_PROC):  Replace
 283         uses of SCM_TRUE_P (x) with SCM_EQ_P (x, SCM_BOOL_T).
 284
 285 2000-06-04  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 286
 287         * eval.c (scm_badformalsp): New static function.
 288         (SCM_CEVAL): Check arguments for procedure-with-setter closures.
 289         (Thanks to Keisuke Nishida.)
 290
 291         The major reason for Guile's slow loading speed has been the fact
 292         that a chain of Scheme level procedures has been evaluated for
 293         every top-level symbol lookup during the first pass through the
 294         code.
 295
 296         The following is a kludge which I suggested four years ago, and
 297         which I've repeatedly suggested since.  Personally, I've never
 298         been bothered by Guile's slow loading speed, so I thought I would
 299         let someone else do it...
 300
 301         But since the new environments will be included first in
 302         Guile-1.5, I thought it would make people happy to get the kludge
 303         into 1.4.
 304
 305         * modules.c: Added #include "libguile/vectors.h";
 306         Added #include "libguile/hashtab.h";
 307         Added #include "libguile/struct.h";
 308         Added #include "libguile/variable.h";
 309         Capture Scheme level `module-make-local-var!' to be used in the
 310         standard eval closure.
 311         (scm_standard_eval_closure): New primitive.
 312
 313         * modules.h (scm_standard_eval_closure): Declare.
 314
 315         * eval.c (scm_lookupcar): Test for !SCM_CONSP (SCM_CAR (env))
 316         instead of SCM_TRUE (scm_procedurep (SCM_CAR (env))).
 317
 318         * symbols.c (scm_sym2vcell): Bypass dispatch in the evaluator for
 319         standard eval closures.
 320
 321         * variable.c: Code layout fixes.
 322
 323 2000-06-03  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 324
 325         * Makefile.am: Added LIBS line to libpath which accidentally
 326         disappeared in the change of 2000-06-01.
 327         (Thanks to Dale P. Smith.)
 328
 329 2000-06-03  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 330
 331         * scmsigs.c (scm_segfault): Removed.  (Was probably added by
 332         mistake since it is not mentioned in ChangeLog.)
 333
 334         * gc.h (SCM_VALIDATE_CELL): Cast result to (void) in order to
 335         avoid compiler warnings in gcc.  (Does this work for other
 336         compilers?)
 337
 338 2000-06-03  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 339
 340         * gc.h (SCM_VALIDATE_CELL): Don't "use" the value returned by
 341         abort ().
 342         (SCM_CARLOC, SCM_CDRLOC): Define directly instead of using
 343         SCM_CELL_OBJECT_0 and SCM_CELL_OBJECT_1.  It's not correct to take
 344         the address of these expressions since they use SCM_VALIDATE_CELL.
 345         (Thanks to Bernard Urban.)
 346
 347         * dynl.c: Changed #include <ltdl.h> --> #include
 348         "libltdl/ltdl.h".  (Thanks to Bill Schottstaedt.)
 349
 350 2000-06-01  Craig Brozefsky  <craig@red-bean.com>
 351
 352         * Makefile.am: libguile_la_LDFLAGS gets -version-info args
 353         from GUILE-VERSION definition of LIBGUILE version.  Added to
 354         libpath.h definitions for guileversion and libguileversion which
 355         both get their values from GUILE-VERSION definition.
 356
 357 2000-05-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 358
 359         * numbers.h (SCM_BIGP):  Don't use SCM_SMOB_PREDICATE in header
 360         file:  Code using numbers should not be required to include
 361         smob.h.
 362
 363 2000-05-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 364
 365         * coop-threads.c.cygnus, coop-threads.h.cygnus, fsu-pthreads.h,
 366         mit-pthreads.c, mit-pthreads.h:  Deleted.
 367
 368         * Makefile.am (EXTRA_DIST), scmsigs.c, threads.[ch]:  Drop
 369         references to deleted files and fsu/mit thread support in
 370         general.
 371
 372 2000-05-29  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 373
 374         * hooks.c (symbol_name, scm_create_hook):  Restored the original
 375         behaviour of scm_create_hook.  Changing it was bad as Carl
 376         R. Witty has pointed out.
 377
 378         * gc.c (scm_init_gc):  We can still rely on scm_create_hook to
 379         protect the object.
 380
 381 2000-05-26  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 382
 383         * gc.c (scm_init_gc):  Protect scm_after_gc_hook, since this will
 384         soon not be done by scm_create_hook any longer.
 385
 386         * hooks.c (make_hook, print_hook, scm_create_hook,
 387         scm_make_hook_with_name, scm_make_hook), hooks.h (SCM_HOOK_NAME,
 388         SCM_HOOK_PROCEDURES, SCM_SET_HOOK_PROCEDURES,
 389         scm_make_hook_with_name), init.c (scm_boot_guile_1):  Hooks no
 390         longer have names.  As an intermediate solution, the name
 391         predicate is emulated via object properties, but use of this
 392         feature is deprecated.
 393
 394         * hooks.h (scm_free_hook):  Removed, as it is never defined.
 395
 396 2000-05-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 397
 398         * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_FIXABLE):
 399         Un-deprecated since otherwise user code can't determine whether a
 400         number fits into an inum any longer.  The names should be changed
 401         some time, though.
 402
 403         * numbers.c (scm_big2inum):  Eliminated use of SCM_UNEGFIXABLE.
 404
 405         * tags.h (SCM_UNPACK_CAR):  Deprecated.
 406
 407 2000-05-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 408
 409         * filesys.h (SCM_OPDIRP), fluids.h (SCM_FLUIDP, SCM_FLUID_NUM),
 410         fports.h (SCM_OPFPORTP, SCM_OPINFPORTP, SCM_OPOUTFPORTP), hooks.h

 412         numbers.h (SCM_NUMP, SCM_BIGSIGN, SCM_BDIGITS, SCM_NUMDIGS):
 413         Replace SCM_UNPACK_CAR appropriately.  Don't access cells via
 414         SCM_{SET}?C[AD]R unless they are known to be cons cells.
 415
 416         * gc.c (scm_heap_seg_data_t, scm_mark_locations, scm_cellp,
 417         init_heap_seg):  Remove unused struct member variable 'valid'.
 418
 419 2000-05-24  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 420
 421         * fports.c (fport_write), ports.c (scm_markstream, scm_port_mode,
 422         scm_print_port_mode), ports.h (SCM_OPPORTP, SCM_OPINPORTP,
 423         SCM_OPOUTPORTP, SCM_INPUT_PORT_P, SCM_OUTPUT_PORT_P, SCM_OPENP),
 424         procs.h (SCM_CLOSCAR), unif.h (SCM_ARRAY_NDIM, SCM_ARRAY_CONTP),
 425         variable.h (SCM_VARIABLEP):  Replace SCM_UNPACK_CAR
 426         appropriately.
 427
 428 2000-05-23  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 429
 430         * gc.c (free_list_length), hash.c (scm_hasher), macros.c
 431         (scm_macro_type), objects.c (scm_class_of), options.c
 432         (scm_options), print.c (scm_iprin1), strports.c (st_seek), throw.c
 433         (SCM_LAZY_CATCH_P):  Replace SCM_UNPACK_CAR appropriately.
 434
 435 2000-05-23  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 436
 437         * eval.c (scm_macroexp, SCM_CEVAL, scm_force), tags.h:  Replace
 438         SCM_UNPACK_CAR with SCM_CELL_TYPE or SCM_CELL_WORD_0.
 439
 440         * eval.c (scm_force):  Add documentation.
 441
 442         * eval.c (scm_force, scm_cons_source):  Don't access cells via
 443         SCM_{SET}?C[AD]R unless they are known to be cons cells.
 444
 445 2000-05-23  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 446
 447         * strings.h (SCM_NSTRINGP, SCM_NRWSTRINGP), tags.h
 448         (SCM_NDOUBLE_CELLP), vectors.h (SCM_NVECTORP):  Deprecated.
 449
 450         * gc.c (scm_igc), gc.h (SCM_PTR_MASK, SCM_PTR_LT):  Removed #ifdef
 451         nosve #endif conditionally compiled code.
 452
 453 2000-05-23  Michael Livshin  <mlivshin@bigfoot.com>
 454
 455         * gc.c (scm_heap_seg_data_t): fixed comment for the `span' member.
 456
 457 2000-05-22  Michael Livshin  <mlivshin@bigfoot.com>
 458
 459         * guile-doc-snarf.in: put the preprocessed file through sed to
 460         trim all lines to 1024 chars.  I hope it doesn't break anybody's
 461         sed.  we'll see.  (note: this is lossy trimming, i.e. the spill
 462         isn't wrapped around but actually chopped off.  this seemed to me
 463         safe because the current snarfer doesn't understand multi-line
 464         cookies anyway.  in the long term, it would be nice not to depend
 465         on AWK for anything.)
 466
 467         * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): reverted
 468         the previous change to this macros, after deciding to torture the
 469         snarfer instead.
 470
 471 2000-05-21  Michael Livshin  <mlivshin@bigfoot.com>
 472
 473         * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): brought
 474         the yucky, ugly and nasty conditional compilation back.  sorry,
 475         but it was either that or requiring GAWK to build Guile.
 476         (lots of places): removed the code that implemented the old GC
 477         scheme.
 478
 479         * init.c (scm_boot_guile_1): removed the code conditioned on
 480         !GUILE_NEW_GC_SCHEME.
 481
 482         * __scm.h: (GUILE_NEW_GC_SCHEME): removed.
 483
 484         * gc.c (scm_protect_object, scm_unprotect_object): change the
 485         implementation to more efficient (at least in the time complexity
 486         sense).  the calls should now also be thread-safe -- I suspect
 487         that people expect them to be.  (thanks to Han-Wen Nienhuys)
 488         (lots of places): removed the code that implemented the old GC
 489         scheme.
 490
 491         * hashtab.c (scm_hash_fn_create_handle_x): add missing
 492         SCM_REALLOW_INTS before return.  I really wonder about the
 493         possible interactions between hashtables, threads & GC.  it
 494         doesn't look healthy at all.
 495
 496 2000-05-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 497
 498         * unif.c (scm_bit_count):  Fixed the parameter checks.  Thanks to
 499         Dale P. Smith.
 500
 501 2000-05-19  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 502
 503         * __scm.h (SCM_DEBUG_CELL_ACCESSES), gc.h (SCM_):  Added as a new
 504         debug option to verify all accesses to cells actually access
 505         objects on the heap.
 506
 507         * gc.h (SCM_VALIDATE_CELL):  Added.  Only performs validation if
 508         SCM_DEBUG_CELL_ACCESSES is set to 1.
 509
 510         (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
 511         SCM_SET_CELL_OBJECT):  Use SCM_VALIDATE_CELL to check every cell
 512         that is accessed.
 513
 514 2000-05-19  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 515
 516         * gh_data.c (gh_scm2chars, gh_scm2shorts, gh_scm2longs,
 517         gh_scm2floats, gh_scm2doubles):  Change !SCM_NIMP to SCM_IMP.
 518
 519         * gc.c (scm_cellp):  Fixed and simplified.
 520
 521         * throw.c (JBJMPBUF, SETJBJMPBUF, SCM_JBDFRAME, SCM_SETJBDFRAME,
 522         make_jmpbuf, scm_init_throw):  Now using double cells to represent
 523         jump buffers when using debug extensions.
 524
 525         (freejb):  Removed.
 526
 527 2000-05-18  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 528
 529         * gh.h gh_data.c gh_funcs.c (gh_new_procedure*, gh_chars2byvect,
 530         gh_shorts2svect, gh_longs2ivect, gh_ulongs2uvect, gh_floats2fvect,
 531         gh_doubles2dvect, gh_doubles2scm, gh_define, gh_lookup,
 532         gh_module_lookup):  Accept const pointers as parameters.
 533
 534         * gh.h gh_data.c (gh_int2scmb):  Deprecated.
 535
 536 2000-05-18  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 537
 538         * __scm.h (SCM_DEBUG_REST_ARGUMENT):  Renamed from
 539         SCM_DEBUG_REST_ARGUMENTS in order to clarify that we don't test
 540         the actual arguments in the list, but rather the rest argument as
 541         a list of arguments.
 542
 543         * validate.h (SCM_VALIDATE_REST_ARGUMENT):  Added.
 544
 545         * async.c (scm_noop), eval.c (scm_map, scm_for_each), list.c
 546         (scm_list_star, scm_append, scm_append_x), ports.c
 547         (scm_close_all_ports_except), ramap.c (scm_array_map_x,
 548         scm_array_for_each), regex-posix.c (scm_make_regexp), stacks.c
 549         (scm_make_stack), strings.c (scm_string_append), struct.c
 550         (scm_make_struct, scm_make_vtable_vtable):  Validate rest arguments.
 551
 552         * dynl.c (DYNL_GLOBAL, sysdep_dynl_link, kw_global, sym_global,
 553         scm_dynamic_link, scm_init_dynamic_linking), dynl.h
 554         (scm_dynamic_link):  Removed possibility to pass flags to
 555         scm_dynamic_link, as it had no effect anyway.
 556
 557         * filesys.c (scm_fcntl):  Made single optional rest argument into
 558         a standard optional argument.
 559
 560         * hooks.c (scm_run_hook):  A list of rest arguments is never
 561         SCM_UNBNDP.
 562
 563         * list.c (scm_append, scm_append_x), stacks.c (scm_make_stack),
 564         strings.c (scm_string_append):  Don't perform half-hearted checks
 565         to see whether the rest argument forms a proper list any more, use
 566         SCM_VALIDATE_REST_ARGUMENTS instead.
 567
 568         * ports.c (scm_close_all_ports_except):  Accept empty list of rest
 569         arguments.
 570
 571         * posix.c (scm_convert_exec_args), print.c (scm_simple_format):
 572         Simplify verification of rest argument.
 573
 574         * stacks.c (scm_make_stack), stacks.h (scm_make_stack), throw.c
 575         (ss_handler, handler_message):  Make first mandatory rest argument
 576         of scm_make_stack into a standard mandatory argument.
 577
 578         * unif.c (scm_transpose_array, scm_enclose_array,
 579         scm_array_in_bounds_p), unif.h (scm_transpose_array,
 580         scm_enclose_array, scm_array_in_bounds_p):  Make first mandatory
 581         rest argument into a standard mandatory argument.
 582
 583 2000-05-17  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 584
 585         * __scm.h:  Added SCM_DEBUG as default debug option. (Thanks to
 586         Keisuke Nishida for the suggestion.)  Added debug option
 587         SCM_DEBUG_REST_ARGUMENTS.
 588
 589         * eval.c (scm_map, scm_for_each):  Make sure all lists have the
 590         same length.  Also, removed redundant parameter checks.
 591
 592 2000-05-16  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 593
 594         * Makefile.am:  Let 'make clean' remove *.x and *.doc files.
 595
 596         * __scm.h:  Improved explanation of giving options to make.
 597
 598         * __scm.h (SCM_DEBUG_TYPING_STRICTNESS), tags.h
 599         (SCM_STRICT_TYPING, SCM_DEBUG_TYPING_STRICTNESS):  Renamed
 600         SCM_STRICT_TYPING to SCM_DEBUG_TYPING_STRICTNESS and moved the
 601         corresponding declaration and comment to __scm.h.
 602
 603         * _scm.h (errno), gc.h (SCM_CELLPTR, SCM_PTR_LT), numbers.c
 604         (scm_remainder, scm_modulo), numbers.h (SCM_SRS, SCM_MAKINUM,
 605         SCM_INUM):  Removed conditionally compiled code for Turbo C.
 606
 607         * gdbint.c (gdb_maybe_valid_type_p):  Eliminated call to scm_tag.
 608         That check can be assumed to be redundant except for very rare
 609         conditions that actually indicate broken heap data.
 610
 611 2000-05-16  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 612
 613         * numbers.c (scm_logcount, scm_integer_length):  Reordered
 614         dispatch sequence.
 615
 616 2000-05-15  Gary Houston  <ghouston@arglist.com>
 617
 618         * stime.c (scm_strftime): don't reset TZ if zone is an empty
 619         string.  append a "0" to the zone for TZ.
 620
 621 2000-05-15  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 622
 623         * numbers.c (scm_logbit_p, scm_bit_extract):  Reordered dispatch
 624         sequence.
 625
 626         (scm_bit_extract):  Fixed handling of bignums.
 627
 628 2000-05-15  Dirk Herrmann  <D.Herrmann@tu-bs.de>

 631         SCM_MAKICHR), continuations.h (SCM_SETJMPBUF), error.c
 632         (scm_sysmissing), error.h (scm_sysmissing), evalext.c

 638         (scm_tc16_flo, scm_tc_flo, scm_tc_dblr, scm_tc_dblc):  Wrapped
 639         deprecated code between #if (SCM_DEBUG_DEPRECATED == 0) #endif.
 640
 641         * fports.c (scm_fport_buffer_add), ports.c (scm_input_port_p,
 642         scm_output_port_p), print.c (scm_get_print_state), validate.h
 643         (SCM_VALIDATE_CHAR):  Replace use of deprecated macros
 644         SCM_INPORTP, SCM_OUTPORTP, SCM_ICHRP by SCM_INPUT_PORT_P,
 645         SCM_OUTPUT_PORT_P, SCM_CHARP, respectively.
 646
 647 2000-05-14  Gary Houston  <ghouston@arglist.com>
 648
 649         * stime.c (scm_strftime): if HAVE_TM_ZONE is not defined, hack the
 650         TZ environment variable so that the %Z format returns the zone
 651         from the input vector instead of the system default.
 652
 653         from Keisuke Nishida:
 654         * fports.c (scm_setvbuf): minor docstring fix.
 655         * ports.h (scm_generic_fgets): obsolete prototype deleted.
 656
 657 2000-05-11  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 658
 659         * __scm.h:  Added new section for debugging options.
 660
 661         (SCM_DEBUG_DEPRECATED):  If 1, no deprecated code is included to
 662         help developers to get rid of references to deprecated code.
 663
 664         * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_UNEGFIXABLE,
 665         SCM_FIXABLE, SCM_FLOBUFLEN):  These macros are no longer provided
 666         as part of the interface and are marked as deprecated in the
 667         header file.
 668
 669         * numbers.c (scm_make_real, scm_make_complex):  Inlined the
 670         corresponding macros SCM_NEWREAL and SCM_NEWCOMPLEX,
 671         respectively.
 672
 673         * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX, SCM_INEXP, SCM_CPLXP,
 674         SCM_REAL, SCM_IMAG, SCM_REALPART, scm_makdbl, SCM_SINGP,
 675         SCM_NO_BIGDIG, SCM_NUM2DBL, scm_dblproc):  Deprecated.
 676
 677 2000-05-10  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 678
 679         * gc.h (scm_cell, SCM_CELL_WORD, SCM_CELL_OBJECT,
 680         SCM_SET_CELL_WORD, SCM_SET_CELL_OBJECT):  Scheme cells now consist
 681         of two scm_bits_t values instead of two SCM values, because it is
 682         legal for cell entries to hold values that are not scheme objects.
 683
 684         (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR):
 685         Use SCM_SETC[AD]R to modify contents of pairs.
 686
 687 2000-05-10  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 688
 689         * numbers.c (IS_INF, isfinite):  Added FIXME comment.
 690
 691         (scm_abs, scm_magnitude):  Make these two independent of each
 692         other.  scm_abs now reports an error if given a complex argument.
 693
 694         (scm_istr2flo, scm_integer_p).  Use SCM_REAL_VALUE instead of
 695         SCM_REALPART if the object is known to be real.
 696
 697         (scm_init_numbers):  No need to use SCM_NEWREAL macro for speed
 698         here.
 699
 700         * numbers.h (SCM_SINGP):  Set to 0 instead of SCM_BOOL_F.
 701
 702 2000-05-10  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 703
 704         * eq.c (scm_eqv_p):  Separate handling of real and complex
 705         values.  Remove #ifdef SCM_BIGDIG #endif test.
 706
 707         * eval.c (SCM_CEVAL, SCM_APPLY), gh_data.c (gh_scm2floats,
 708         gh_scm2doubles), hash.c (scm_hasher), ramap.c (scm_array_fill_int,
 709         ramap_rp, scm_array_map_x), random.c (vector_scale,
 710         vector_sum_squares), unif.c (scm_make_uve, scm_array_p,
 711         scm_array_set_x):  Use SCM_REAL_VALUE instead of SCM_REALPART if
 712         the object is known to be real.  Use SCM_COMPLEXP instead of
 713         deprecated SCM_CPLXP.  Use SCM_INEXACTP instead of deprecated
 714         SCM_INEXP.
 715
 716 2000-05-10  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 717
 718         * numbers.c:  No need to include unif.h.
 719
 720         (IS_INF):  Returned to old test for now:  x == x + 1 will not work
 721         for large numbers due to rounding errors.
 722         Thanks to Kalle Olavi Niemitalo.
 723
 724 2000-05-09  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 725
 726         * numbers.c (scm_divbigdig):  Removed outdated comment.
 727
 728         (scm_number_to_string, scm_string_to_number, scm_number_p,
 729         scm_real_p, scm_integer_p, scm_inexact_p, scm_gr_p, scm_leq_p,
 730         scm_geq_p, scm_make_rectangular, scm_make_polar,
 731         scm_inexact_to_exact):  Added comments.
 732
 733         (add1, scm_init_numbers):  Removed add1.
 734
 735 2000-05-09  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 736
 737         * numbers.c (IS_INF):  The new test is x == x + 1.  The old test
 738         x == x/2 did not work for zero values.  Thanks to Han-Wen Nienhuys
 739         and Ivan Toshkov.
 740
 741         (scm_number_to_string, scm_sum, scm_difference, scm_two_doubles,
 742         scm_num2long, scm_num2long_long, scm_num2ulong):  Reordered
 743         dispatch sequence.
 744
 745 2000-05-09  Marius Vollmer  <mvo@zagadka.ping.de>
 746
 747         * scmsigs.c (take_signal): Execute SCM_ASYNC_TICK for SIGSEGV,
 748         SIGILL and SIGBUS signals.  These signals are not continuable and
 749         must be handled for real right away.
 750
 751 2000-05-08  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 752
 753         * numbers.c (scm_zero_p, scm_positive_p, scm_negative_p,
 754         scm_real_part, scm_imag_part, scm_magnitude,
 755         scm_inexact_to_exact):  Reordered dispatch sequence.
 756
 757 2000-05-08  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 758
 759         * feature.c:  No need to include "libguile/smob.h"
 760
 761         (scm_loc_features, features, scm_add_feature, scm_init_feature):
 762         Removed variable 'scm_loc_features' as a pointer to the SCM value
 763         holding the features list.  Using variable 'features' instead,
 764         which holds the interned pair.  Thus, SCM_SETCDR can be used
 765         instead of pointer trickery.
 766
 767 2000-05-08  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 768
 769         * alist.c (scm_acons):  Use SCM{_SET}?_CELL_OBJECT as long as a
 770         cell is not known to be a valid pair.
 771
 772 2000-05-08  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 773
 774         * eval.c (ASRTSYNTAX, scm_m_body, scm_m_letrec1):  Removed
 775         ASRTSYNTAX.  Using SCM_ASSYNT instead.
 776
 777         (scm_m_body):  Don't create a redundant cons cell.
 778
 779         (scm_m_do):  Removed redundant test 'bodycheck'.
 780
 781         (bodycheck):  Removed.
 782
 783         * stacks.c (stack_depth, read_frame, read_frames):  Removed
 784         redundant calculation of size, minimized some variable scopes.
 785
 786 2000-05-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 787
 788         * pairs.c (scm_cons, scm_cons2):  Use SCM{_SET}?_CELL_OBJECT as
 789         long as a cell is not known to be a valid pair.
 790
 791         (scm_pair_p):  Eliminated redundant SCM_IMP test.
 792
 793 2000-05-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 794
 795         * eval.c (scm_m_body, scm_macroexp, unmemocopy, scm_eval_args,
 796         scm_deval_args):  Eliminated redundant SCM_IMP tests.
 797
 798         * hashtab.c (scm_ihashx, scm_sloppy_assx, scm_delx_x), weaks.c
 799         (scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
 800         scm_make_doubly_weak_hash_table):  Fixed critical sections.
 801         Thanks to Keisuke Nishida.
 802
 803 2000-05-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 804
 805         * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest):
 806         Fixed some goto-related initialization bugs (introduced by me).
 807
 808 2000-05-04  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 809
 810         * numbers.h (SCM_INUM0):  Uses SCM_MAKINUM instead of SCM_PACK.
 811
 812         * dynl.c (dynl_obj, DYNL_OBJ, get_dynl_obj):  Removed.
 813
 814         (DYNL_FILENAME, DYNL_HANDLE):  Use SCM_CELL... macros instead of
 815         pointer trickery.
 816
 817         (SET_DYNL_HANDLE):  Added.
 818
 819         (scm_dynamic_object_p):  Simplified.
 820
 821         (scm_dynamic_unlink, scm_dynamic_func):  Changed comment.  Deliver
 822         better error message when accessing unlinked dynamic objects.
 823         Eliminated call to get_dynl_obj.
 824
 825 2000-05-03  Marius Vollmer  <mvo@zagadka.ping.de>
 826
 827         * scmsigs.c (orig_handlers) [!HAVE_SIGACTION]: Fix declaration to
 828         be an array of function pointers instead of being a pointer to an
 829         array returning function.  Thanks to Kalle Olavi Niemitalo!
 830
 831 2000-05-03  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 832
 833         * numbers.c (scm_divbigbig, scm_divbigint), numbers.h
 834         (scm_divbigbig, scm_divbigint):  Don't return zero any more to
 835         indicate that a division has a remainder, return SCM_UNDEFINED
 836         instead.  It is improbable that anyone actually used these
 837         functions outside of numbers.c.  For this reason and due to the
 838         change in behaviour the functions are static now.  Thus, if
 839         surprisingly there are users of these functions they will at least
 840         get alarmed.
 841
 842         * numbers.c:  Removed #ifdef SCM_BIGDIG #endif in those functions,
 843         that already have a clean dispatch order.  Note: SCM_BIGDIG is
 844         always defined.
 845
 846         * numbers.c (scm_inexact_p):  Simplified.
 847
 848         * numbers.c (scm_num_eq_p, scm_less_p, scm_max, scm_min,
 849         scm_product, scm_num2dbl, scm_angle):  Reordered dispatch
 850         sequence, thereby fixing some comparisons of SCM values with
 851         integer constants.
 852
 853         * numbers.c (scm_divide):  Division by zero of inums leads to an
 854         error now.  (Formerly, an infinite number was returned.)
 855
 856         Respect the fact, that scm_divbigbig does now return SCM_UNDEFINED
 857         if a division has a remainder.
 858
 859 2000-05-02  Gary Houston  <ghouston@arglist.com>
 860
 861         * Makefile.am (INCLUDES): add ${INCLTDL} (thanks to Tim Mooney).
 862
 863 2000-05-02  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 864
 865         * numbers.c (scm_logtest, scm_division):  Reordered dispatch
 866         sequence, thereby fixing some comparisons of SCM values with
 867         integer constants.
 868
 869         * numbers.h (scm_makdbl):  Mark as deprecated at the point of
 870         declaration.
 871
 872         * eval.c (SCM_CEVAL, SCM_APPLY), gh_data.c (gh_double2scm,
 873         gh_doubles2scm), numbers.c (scm_istr2flo, scm_max, scm_min,
 874         scm_sum, scm_difference, scm_product, scm_divide, scm_sys_expt,
 875         scm_sys_atan2, scm_make_rectangular, scm_make_polar,
 876         scm_real_part, scm_imag_part, scm_magnitude, scm_angle,
 877         scm_long2num, scm_long_long2num, scm_ulong2num), ramap.c
 878         (ramap_rp, scm_array_map_x), random.c (scm_random,
 879         scm_random_uniform, scm_random_normal_vector_x, scm_random_exp),
 880         struct.c (scm_struct_ref), unif.c (scm_array_to_list):  Replace
 881         call to scm_makdbl with a call to scm_make_real or
 882         scm_make_complex, depending on whether the imaginary part is known
 883         to be zero.
 884
 885 2000-05-01  Gary Houston  <ghouston@arglist.com>
 886
 887         * scmsigs.c: fix the definition of orig_handlers for the case
 888         that HAVE_SIGACTION is not defined (thanks to
 889         Kalle Olavi Niemitalo).
 890
 891         * Makefile.am: remove include_HEADERS (was libguile.h)
 892         libguile.h: moved to top level directory.
 893
 894 2000-04-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 895
 896         * numbers.c (SCM_SWAP):  Moved to the top of the file to allow for
 897         a wider use.
 898
 899         * numbers.c (scm_modulo, scm_gcd, scm_lcm, scm_logand, scm_logior,
 900         scm_logxor):  Reordered dispatch sequence, thereby fixing some
 901         comparisons of SCM values with integer constants.
 902
 903         * number.c (scm_logtest):  Removed some redundant SCM_{N}?IMP
 904         tests.
 905
 906 2000-04-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 907
 908         * numbers.c (scm_quotient, scm_remainder):  Removed code that was
 909         conditionally compiled based on BADIVSGNS.  BADIVSGNS does not
 910         occur anywhere else throughout guile.
 911
 912         * numbers.c (scm_quotient):  Fixed parameter number in error
 913         message.
 914
 915         * numbers.c (scm_remainder):  Reordered dispatch sequence.
 916
 917 2000-04-25  Gary Houston  <ghouston@arglist.com>
 918
 919         * posix.c (scm_execlp): docstring fix (thanks to Martin
 920         Grabmueller).
 921
 922 2000-04-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 923
 924         * eval.c (undef_object):  Made into a local static variable
 925         (suggested by Jost Boekemeier).
 926
 927 2000-04-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 928
 929         * pairs.c (cxrs, scm_init_pairs):  Simplify initialization of
 930         c[ad]+r functions.
 931
 932         * procs.c (scm_init_iprocs), procs.h (scm_subr, scm_iproc,
 933         scm_dsubr, scm_init_iprocs):  Removed.
 934
 935         * procs.h (SCM_SUBRF, SCM_DSUBRF):  Access the cell words
 936         directly instead of casting a cell to a C struct.
 937
 938 2000-04-22  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 939
 940         Better modularization of GC extensions through new C level GC
 941         hooks:
 942
 943         * weaks.c (scm_weaks_prehistory): New function: Add
 944         scm_weak_vector_gc_init to scm_before_mark_c_hook; Add
 945         scm_mark_weak_vector_spines to scm_before_sweep_c_hook.
 946         (scm_scan_weak_vectors): New function; added to
 947         scm_after_sweep_c_hook.
 948
 949         * weaks.h (scm_weak_vectors, scm_weaks_prehistory): Added
 950         declarations.
 951
 952         * guardians.h (scm_guardian_gc_init, scm_guardian_zombify): Are
 953         now static.
 954
 955         * guardians.c (scm_guardian_gc_init): Turned into a hook function
 956         and added to scm_before_mark_c_hook.
 957         (scm_guardian_zombify): Turned into a hook function and added to
 958         scm_before_sweep_c_hook.
 959
 960         * async.c (scm_sys_gc_async_thunk): Run after-gc-hook.
 961         Added #include "libguile/gc.h".
 962
 963         * gc.h: Added #include "libguile/hooks.h".
 964
 965         * gc.c: Removed #include "libguile/guardians.h".
 966         (scm_before_gc_c_hook, scm_before_mark_c_hook,
 967         scm_before_sweep_c_hook, scm_after_sweep_c_hook,
 968         scm_after_gc_c_hook): New C level hooks.
 969         (scm_after_gc_hook): New Scheme level hook.
 970         (scm_gc_sweep): Moved scanning of weak vectors to weaks.c.
 971         (scm_igc): Moved initialization of scm_weak_vectors and the call
 972         to scm_guardian_gc_init to respective module.
 973         (scm_mark_weak_vector_spines): Moved to weaks.c;
 974         Call to scm_guardian_zombify moved to guardians.c;
 975         Run scm_before_gc_c_hook, scm_before_sweep_c_hook,
 976         scm_after_gc_c_hook at appropriate places.
 977         (scm_init_gc): Initialize scm_after_gc_hook.
 978
 979         * hooks.c, hooks.h (scm_make_hook_with_name): Removed deprecated
 980         function.
 981
 982         * init.c (scm_boot_guile_1): Added `scm_init_hooks'.
 983
 984         * Makefile.am: Added hooks.c, hooks.h, hooks.x.
 985
 986         * feature.c, feature.h: Broke out hook code into separate files.
 987
 988         * hooks.c, hooks.h: New files.
 989

 991         libguile/, qt/, guile-readline/, or libltdl/.
 992         (Thanks to Tim Mooney.)
 993
 994         * Makefile.am (INCLUDES): Removed THREAD_CPPFLAGS and INCLTDL.
 995         (DEFS): Added.  automake adds -I options to DEFS, and we don't
 996         want that.
 997         Removed all -I options except for the root source directory and
 998         the root build directory.
 999
1000         * numbers.c (scm_odd_p, scm_even_p): Use SCM_WRONG_TYPE_ARG
1001         instead of SCM_ASSERT (0, ...).  (Some compilers will complain
1002         about control reaching end of function otherwise, and, besides,
1003         the new code is not less clear.)
1004
1005         * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Added
1006         calls to malloc debugging functions.
1007
1008         * init.c (scm_boot_guile_1): Added calls to debug-malloc init
1009         functions.
1010
1011         * Makefile.am: Added debug-malloc.c, debug-malloc.h,
1012         debug-malloc.x.
1013
1014         * debug-malloc.c, debug-malloc.h: New files.
1015
1016 2000-04-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1017
1018         * numbers.c (scm_exact_p, scm_odd_p, scm_even_p):  Added
1019         documentation strings.
1020
1021         * numbers.c (scm_exact_p, scm_odd_p, scm_even_p, scm_abs,
1022         scm_quotient):  Reordered dispatch sequence to first handle
1023         immediates, second handle bignums and finally handle generic
1024         functions respectively signal wrong type arguments.  Hopefully
1025         this will allow for easier separation when goops is integrated.
1026
1027 2000-04-19  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1028
1029         * gc.c (which_seg):  Use SCM2PTR to convert a non immediate SCM
1030         variable into a pointer to a heap cell.
1031
1032         * gc.c (scm_mark_locations, scm_cellp, init_heap_seg,
1033         scm_unhash_name):  Remove redundant cast to SCM_CELLPTR.
1034
1035 2000-04-19  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1036
1037         * print.c (scm_iprin1):  Don't assign zero to SCM values, use
1038         SCM_UNDEFINED instead.
1039
1040         * weaks.c (scm_make_weak_vector):  Fix assignment of zero to a
1041         vector element.  (Still to be improved)
1042
1043 2000-04-19  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1044
1045         * eval.c (undef_cell):  Removed, replaced by:
1046
1047         (undef_object):  Added to replace undef_cell.
1048
1049         (scm_lookupcar, scm_lookupcar1):  Use undef_object.
1050
1051         * eval.c (scm_lookupcar, scm_lookupcar1, scm_m_atfop,
1052         scm_m_atbind, CHECK_EQVISH, SCM_CEVAL), procs.h (SCM_SETCODE):
1053         Don't perform arithmetic operations with SCM values.

1313
1314         * async.h: kill the scm_async_t struct.  having a heap cell
1315         pretending to be a C struct is not helthy, and is not needed here
1316         anyway, as asyncs happily fit in one heap cell.

1388         Gary Houston).  note that the order problems are still there if
1389         some guardians are themselves zombies, but that's a sick case that
1390         I'm not going to worry about.
1391         also, make another outer loop to process zombified
1392         guardians (which are uncovered while marking zombies).

1483         used).
1484         guardians.c: Added more comments and modified the make-guardian
1485         docstring.  Reordered a few procedures.

1532
1533         * coop-defs.h (struct coop_t): Added `sto'-field again because of
1534         binary compatibility---let's remove it next time we alter some
1535         major structure.
1536
1537         * coop.c (coop_quitting_p, coop_cond_create, coop_mutex_create,

1539         (mother): New function.
1540         (coop_create): New thread spawning mechanism which uses a "mother
1541         thread".  The "dummy" pthreads aren't healthy enough to give birth
1542         to new threads since Linux threads thinks they are asleep.
1543
1544         * coop-defs.h (struct coop_t): Removed dummy_mutex.
1545
1546         * coop-defs.h, coop-threads.c (struct coop_t): Eliminate

1554
1555         * arbiters.c (SCM_ARB_LOCKED, SCM_LOCK_ARB, SCM_UNLOCK_ARB):
1556         Access the locking information in cell entry 0 with
1557         SCM_{SET_}?CELL_WORD_0 instead of SCM_*CAR.
1558
1559         * async.c (scm_run_asyncs):  Use SCM_NULLP to test for the empty
1560         list.

1568
1569         * alist.c (scm_sloppy_assq, scm_assq), eq.c (scm_eq_p, scm_eqv_p,

1572         Don't use C operators == and != to compare SCM values, use
1573         SCM_EQ_P instead.
1574
1575         * boolean.c (scm_boolean_p):  Use SCM_BOOLP to determine whether a
1576         SCM value is equal to #t or #f.
1577
1578         * eq.c (scm_eqv_p, scm_equal_p):  Don't use SCM_CAR to access the
1579         cell type entry of non immediate objects of unknown type.  Use

1596
1597         * coop.c (coop_create): Set `specific' field, not `data' to NULL.
1598
1599 2000-03-29  Dirk Herrmann  <D.Herrmann@tu-bs.de>

1602         SCM_SET_SMOB_DATA, SCM_TC2SMOBNUM, SCM_SMOBNUM):  To access smob
1603         data, use SCM_{SET_}?CELL_TYPE or SCM_{SET_}?WORD_[1-3].
1604
1605         Note that this implies that smob data has always to be passed as
1606         values of type scm_bits_t.
1607
1608 2000-03-29  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
1609
1610         * threads.c (scm_init_threads): Pass 0 size to scm_make_smob_type
1611         for scm_tc16_thread.  As the current COOP threads are written, GC
1612         is not supposed to manage storage for threads.
1613
1614         * error.c (scm_error): Don't try to throw an error if
1615         scm_gc_heap_lock is true.
1616
1617         * coop.c (coop_finish): New function.  Called at exit.
1618         (coop_aborthelp): Free thread structures when threads die.
1619         Finished LinuxThreads compatibility support => COOP threads now
1620         mesh with LinuxThreads.
1621
1622         * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread):
1623         Changed SETCDR --> SET_CELL_WORD_1.

1626         when thread dies.
1627
1628 2000-03-29  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1629
1630         * boolean.h (SCM_TRUE_P):  New macro.
1631

1634
1635 2000-03-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1636
1637         * continuations.h (SCM_CONTREGS, SCM_SET_CONTREGS):  New macros to
1638         access continuation data.
1639
1640         (SCM_SETJMPBUF):  Deprecated.  Use SCM_SET_CONTREGS instead.
1641
1642         (SCM_JMPBUF, SCM_DYNENV, SCM_THROW_VALUE, SCM_BASE, SCM_SEQ,
1643         SCM_DFRAME):  Use SCM_CONTREGS instead of SCM_CHARS to access
1644         continuation data.
1645
1646         * continuations.c (scm_make_cont), init.c (start_stack),
1647         root.c (scm_internal_cwdr):  Use SCM_SET_CONTREGS instead of
1648         SCM_SETJMPBUF.
1649
1650 2000-03-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1651
1652         * symbols.h (SCM_LENGTH, SCM_SETLENGTH):  Access the length field
1653         of strings and symbols by using SCM_{SET_}?CELL_WORD_0.
1654
1655         (SCM_CHARS, SCM_UCHARS, SCM_SETCHARS):  Use SCM_{SET_}?CELL_WORD_1
1656         to access the char * field of strings and symbols.
1657
1658 2000-03-27  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1659
1660         * gc.h (SCM_NEWCELL, SCM_NEWCELL2):  Use SCM_SET_CELL_TYPE to set
1661         the type entry of a new cell.  Added a comment about things to
1662         remember when updating the list of free cells.
1663
1664         (SCM_FREEP, SCM_MARKEDP):  Use SCM_CELL_TYPE to access the type
1665         entry of a cell.
1666
1667 2000-03-27  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1668
1669         * pairs.h (SCM_CAR, SCM_CDR, SCM_SETCAR, SCM_SETCDR):  Use
1670         SCM_CELL_OBJECT and SCM_SET_CELL_OBJECT.  This change implies that
1671         with strict type checking enabled these macros will only work if
1672         given valid SCM parameters.
1673
1674         (SCM_GCCDR):  Moved to tags.h.
1675
1676         * tags.h (SCM_GCCDR):  Moved here from pairs.h.
1677

1689         SCM_SETOR_CAR, SCM_SETOR_CDR):  Moved to gc.h.  These names should
1690         be changed, though, since the macros are not only pair related.
1691
1692         (SCMPTR):  Deleted.
1693
1694         * gc.h (SCM2PTR, PTR2SCM, scm_cell, SCM_CELLPTR, SCM_CELL_WORD*,
1695         SCM_CELL_OBJECT*, SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*,

1703
1704         * tags.h (SCM_STRICT_TYPING):  New macro that, if defined,
1705         activates strict compile time type checking for variables of
1706         type SCM.
1707         (SCM, SCM_PACK, SCM_UNPACK):  Define according to whether
1708         SCM_STRICT_TYPING or SCM_VOIDP_TEST are defined.
1709         (SCM_EQ_P):  Defined as a macro equivalent for eq?.
1710
1711 2000-03-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1712
1713         * tags.h (SCM_POINTERS_MUNGED):  Removed.
1714
1715         * gc.c (scm_gc_sweep, init_heap_seg):  Removed use of
1716         SCM_POINTERS_MUNGED, thus fixing some illegal casts to SCM.
1717
1718 2000-03-24  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1719
1720         * pairs.h (SCM_CELL_OBJECT, SCM_CELL_OBJECT_[0-3],
1721         SCM_SET_CELL_OBJECT, SCM_SET_CELL_OBJECT_[0-3], SCM_CELL_TYPE,
1722         SCM_SET_CELL_TYPE):  Added a set of low level macros for accessing
1723         cell entries.
1724         (SCM_CELL_WORD_[0-3]): Renamed from the SCM_CELL_WORD[0-3].
1725
1726         * procs.h, procs.c:  Instead of SCM_{SET_}?CELL_WORD[12], use the
1727         newly introduced SCM_{SET_}?CELL_OBJECT_[12] macros.
1728
1729 2000-03-23  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1730
1731         * tags.h: Disabled definition of SCM_VOIDP_TEST.
1732
1733         Defining SCM as void * introduces problems which haven't been
1734         handled yet.  Developers who work with these issues can enable it
1735         in their working copies.
1736
1737         Disabling this definition exposes a set of newly introduced and
1738         older misuses of types which causes warning messages during
1739         compilation.  We'll fix this successively.
1740
1741         * gc.c (scm_mark_locations): Changed * (SCM **) X --> * (SCM *) X
1742         in order to obtain a value of type SCM.
1743         (scm_cellp): Updated with new changes to scm_mark_locations.
1744
1745         * continuations.h (SCM_SETJMPBUF): Cast second arg into SCM.
1746
1747         * continuations.c (scm_make_cont): Removed cast of size_t into
1748         long.
1749
1750         * symbols.h (SCM_SETCHARS): Cast second arg into SCM.
1751
1752 2000-03-22  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1753
1754         * numbers.h (SCM_SETNUMDIGS):  Use SCM_BIGSIZEFIELD macro for
1755         shifting, not constant.  Thanks to Dale P. Smith.
1756
1757         * numbers.c (scm_sum, scm_difference):  Don't test a SCM value
1758         for being less than zero.  Decode it to a C value first.  Again,
1759         thank you Dale.
1760
1761 2000-03-22  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1762
1763         * numbers.h, ramap.c, struct.h, vectors.h:  Don't use SCM2PTR for
1764         non scheme values.  If raw data is stored in SCM variables, it has
1765         to be accessed using SCM_UNPACK until a better solution is found.
1766
1767 2000-03-22  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1768
1769         * tags.h (SCM_ECONSP, SCM_NECONSP): More corrections of
1770         pointer-arithmetic induced by the SCM_PACK/UNPACK change.
1771
1772         * print.c (scm_iprin1): SCM_PACK/UNPACK corrections.
1773
1774         * gc.c (scm_gc_sweep): SCM_PACK/UNPACK corrections.
1775
1776         * eval.c (SCM_CEVAL, scm_unmemocar): SCM_PACK/UNPACK corrections.
1777
1778         * dynwind.c (scm_swap_bindings): SCM_PACK/UNPACK corrections.
1779
1780         * async.c, __scm.h: Removed lots of the old async click logic.  It
1781         is possible to reinsert it by defining GUILE_OLD_ASYNC_CLICK in
1782         __scm.h.  Let's try this out and dump the old code after the
1783         threads reorganization.
1784         (set-tick-rate, set-switch-rate): Conditionally removed.
1785
1786 2000-03-21  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1787
1788         * gc.c (scm_gc_mark): Bugfix 1: The recent SCM_PACK/UNPACK change
1789         made SCM values into pointers.  This turned an arithmetic
1790         computation of the address of the vcell into a pointer-arithmetic
1791         one, thereby screwing up marking of structs.
1792         Bugfix 2: Removed incompletely introduced loop variable `j' used
1793         when protecting the tail array of a struct.
1794
1795 2000-03-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1796
1797         * struct.h (SCM_STRUCT_DATA):  Don't cast SCM values to pointers.
1798
1799 2000-03-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1800
1801         * symbols.h, symbols.c (scm_strhash):  Declare the string
1802         parameter as constant, since it is not modified.
1803
1804         * symbols.c (scm_intern_obarray_soft,
1805         scm_sysintern0_no_module_lookup):  Can now pass constant strings
1806         to scm_strhash without need for casting.
1807
1808 2000-03-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1809
1810         * vectors.h (SCM_VELTS, SCM_VELTS_AS_STACKITEMS):  Don't cast SCM
1811         values to pointers.  Use SCM2PTR instead.
1812
1813 2000-03-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1814
1815         * async.c (scm_set_tick_rate, scm_set_switch_rate):  Don't unpack
1816         results of SCM_INUM.
1817
1818 2000-03-21  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
1819
1820         * init.c (scm_boot_guile_1): Renamed GUILE_GC_TRIGGER_1 -->
1821         GUILE_MIN_YIELD_1, GUILE_GC_TRIGGER_2 --> GUILE_MIN_YIELD_2.
1822         GUILE_MIN_YIELD_X now take *positive* fractions of heap size.
1823
1824         * gc.c, gc.h (SCM_MIN_YIELD_1, SCM_MIN_YIELD_2,
1825         min_yield_fraction, min_yield, adjust_min_yield): Renamed from
1826         SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2, gc_trigger_fraction,
1827         gc_trigger, adjust_gc_trigger.
1828
1829         * gc.c (alloc_some_heap): Further improvement of minimal heap size
1830         prediction.
1831         (SCM_MAX): New macro.
1832         (scm_freelist_t): New field: collected_1. Previous amount of
1833         collected cells.
1834         (gc_sweep_freelist_finish): Trigger based on two last values of
1835         freelist->collected to avoid unnecessary allocation due to
1836         temporary peaks.
1837         (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2):
1838         Adjusted to 45000 cells, 40% and 40%.  Gives quick startup
1839         without extra heap allocation.
1840
1841 2000-03-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1842
1843         * numbers.h (SCM_MAKINUM):  The parameter to SCM_MAKINUM should
1844         already be a C value.  No need to unpack it.
1845
1846         * numbers.c (scm_long_long2num):  Cast the parameter to scm_bits_t
1847         if we know it fits into an inum.
1848
1849         * ramap.c (ramap_rp):  An scm_tc7_[ui]vect object does point to a
1850         field of long values.  In contrast, SCM_VELTS accesses a field of
1851         SCM values.
1852
1853 2000-03-20  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1854
1855         * gc.c (scm_gc_stats): Inserted explanation of local_scm_mtrigger
1856         etc.
1857         (scm_gc_yield_1): New variable: Holds previous yield.  Used to
1858         make better judgements.
1859         (gc_sweep_freelist_finish): Inserted explanation of use of
1860         gc_trigger.
1861
1862         * print.h, stacks.h, options.c, options.h: Changed C++
1863         commentaries to C.
1864
1865 2000-03-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1866
1867         * tags.h (SCM2PTR, PTR2SCM):  Use SCM_PACK / SCM_UNPACK correctly.
1868
1869         * numbers.h (SCM_INUMP, SCM_MAKINUM, SCM_INUM0, SCM_COMPLEX_REAL,
1870         SCM_COMPLEX_IMAG, SCM_NUMP, SCM_BDIGITS):  Use SCM_PACK /
1871         SCM_UNPACK / SCM2PTR correctly.
1872
1873 2000-03-20  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1874
1875         * gc.c (adjust_gc_trigger): Improved documentation.
1876         (alloc_some_heap): Since gc_trigger is used against
1877         freelist->collected, this is the value which should be used to
1878         predict minimum growth.
1879
1880 2000-03-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1881
1882         * eval.h:  Fix mixup of packed/unpacked SCM values.  (Thanks
1883         Thien-Thi Nguyen for the patch.)
1884
1885 2000-03-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>
1886
1887         * numbers.c (scm_ash):  Fixed typing problems with the second
1888         parameter and added some documentation.  (Thanks Thien-Thi Nguyen
1889         for indicating the problem.)
1890
1891 2000-03-19  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1892
1893         * gc.c, gc.h (scm_gc_yield): New variable.
1894         (adjust_gc_trigger): Use scm_gc_yield.
1895         (alloc_some_heap): Use scm_gc_yield instead of
1896         scm_gc_cells_collected.
1897
1898         * coop-threads.c: Addd #include "root.h", #include "strings.h".
1899
1900         * debug.c: Added #include "root.h".  (Thanks to Thien-Thi Nguyen.)
1901
1902         * gc.c (scm_gc_for_newcell, adjust_gc_trigger): Improved GC
1903         trigger adjustmeant: Take yield (freed cells) for all freelists
1904         into account.
1905         (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Tuned
1906         to 50000 cell heap with 45% trigger.
1907         (scm_gc_cells_collected): Reintroduced.
1908         (SCM_HEAP_SIZE): New macro.
1909         (scm_gc_sweep): Reintroduced correct computation of
1910         scm_cells_allocated.
1911         (scm_freelist_t): Corrected commentary for field `cluster_size':
1912         Clustersize counts objects, not cells;  New member
1913         `clusters_allocated'.
1914
1915 2000-03-19  Michael Livshin  <mlivshin@bigfoot.com>
1916
1917         * *.[hc]: add Emacs magic at the end of file, to ensure GNU
1918         indentation style.
1919
1920 2000-03-19  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
1921
1922         * threads.h: Added #include "libguile/throw.h".  (Thanks to
1923         Thien-Thi Nguyen.)
1924
1925 2000-03-18  Michael Livshin  <mlivshin@bigfoot.com>
1926
1927         * tags.h: (SCM_DOUBLE_CELLP, SCM_NDOUBLE_CELLP): new macros (bad
1928         names, anyone got any better ones?)
1929
1930         * gc.h: (typedef struct scm_freelist_t) remove from here.
1931
1932         * gc.c: (CELL_UP, CELL_DN) made these macros take additional
1933         parameter (the span).
1934         (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK) new macros.
1935         (typedef struct scm_freelist_t) moved here from gc.h, it had no
1936         business being externally visible.
1937         (typedef struct scm_heap_seg_data_t) renamed from
1938         scm_heap_seg_data, to be style-compliant.
1939         (scm_mark_locations) if the possible pointer points to a
1940         double-cell, check that it's properly aligned.
1941         (init_heap_seg) align double-cells properly, work with the
1942         assumption that the segment size divides cleanly by cluster size.
1943         (round_to_cluster_size) new function.
1944         (alloc_some_heap, make_initial_segment) use round_to_cluster_size
1945         to satisfy the new init_heap_seg invariant.

2004 2000-03-17  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
2005
2006         * gc.c, gc.h: Cleanup of the change of 2000-03-15.
2007         Cluster sizes are now independent of GC trigger values.
2008         GUILE_GC_TRIGGER_n can now specify a relative trigger value:
2009         A negative integer gives fraction of total heap size in percent.
2010         (SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Default values set to -40.
2011
2012         * init.c (scm_boot_guile_1): Introduced new variable
2013         GUILE_MAX_SEGMENT_SIZE; New environment variable names:
2014         GUILE_INIT_SEGMENT_SIZE_1, GUILE_GC_TRIGGER_1,
2015         GUILE_INIT_SEGMENT_SIZE_2, GUILE_GC_TRIGGER_2
2016
2017 2000-03-16  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
2018
2019         * __scm.h (GC_FREE_SEGMENTS): Disable this until we have made
2020         freeing of segment work with the new GC scheme.  (Thanks to
2021         Michael Livshin.)  Oops, also happened to make GUILE_NEW_GC_SCHEME
2022         the default, but I'll let this change stay in CVS Guile since this
2023         code is not expected to contain serious bugs.
2024
2025 2000-03-16  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
2026
2027         * gc.c, gc.h (scm_map_free_list): Define also if GUILE_DEBUG is
2028         defined.
2029         (scm_free_list_length): New procedure (GUILE_DEBUG).
2030         Fixed a small but serious bug introduced by the previous change.
2031
2032         * gc.c (scm_gc_sweep): Moved variable n_objects to inner sweep
2033         loop and declare as register.
2034
2035         * gc.c (scm_gc_sweep): Sigh... forgot to clear private freelists
2036         after GC.

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

2370
2371         * numbers.c (scm_copy_big_dec, scm_copy_smaller, scm_big_ior,
2372         scm_big_xor, scm_big_and, scm_big_test): Added new lowlevel bignum
2373         logical functions from SCM.
2374
2375         (logand, logior, logxor, logtest, logbit?): Extended scheme
2376         logical functions to use bignums from SCM.
2377
2378         (lognot): Removed call to `SCM_VALIDATE_INUM' that prevented
2379         lognot from using bignums.

2381 Thu Mar  9 11:33:25 2000  Greg J. Badros  <gjb@cs.washington.edu>
2382
2383         * vectors.h (SCM_VELTS_AS_STACKITEMS): Added this macro to help in
2384         eliminating some warnings.
2385
2386         * unif.c, strports.c, print.c, options.c: Fix some warnings on
2387         mis-use of SCM/long
2388
2389         * gc.c, gc.h: Added scm_return_first_int(), and added comment re:
2390         what the scm_return_first* functions do.

2393
2394        * libguile/*.[ch]: make a distinction between SCM as a generic
2395        name for a Scheme object (now a void*), and SCM as 32 bit word for
2396        storing tags and immediates (now a long int).  Introduced
2397        SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
2398        code in the process: arbiter.c (use macros), unif.c (scm_array_p),

2400 Wed Mar  8 10:15:59 2000  Greg J. Badros  <gjb@cs.washington.edu>
2401
2402         * numbers.c:  Use SCM_VALIDATE_LONG_COPY, and longs, not ints, in
2403         various logXXX primitives.  Thanks Eric Moore!
2404
2405 Tue Mar  7 08:05:22 2000  Greg J. Badros  <gjb@cs.washington.edu>
2406
2407         * run-test, remaining-docs-needed:  Added these scripts.  The
2408         second one is only temporary until the docstring additions are
2409         complete.   run-test may best live on, but is here mostly for
2410         convenience and awareness for now.
2411
2412         * hash.c: Docs, minor cleanup patch from Dirk Herrman.
2413
2414 Thu Mar  2 16:06:58 2000  Greg J. Badros  <gjb@cs.washington.edu>
2415
2416         * error.h, error.c: Added `scm_wrong_type_arg_msg' to support
2417         displaying the expected type.  Use SCM_LISTn in a couple places
2418         instead of scm_cons-ing by hand.
2419
2420         * __scm.h: Added SCM_ASSERT_TYPE macro.
2421
2422         * validate.h, scm_validate.h: Added the former, as a renamed
2423         version of the latter with SCM_ASSERT_TYPE used in
2424         SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
2425
2426         * Makefile.am: Rename scm_validate.h to validate.h.
2427
2428         * *.c, *.h: Include validate.h, not scm_validate.h (old name's
2429         prefix was superfluous).
2430
2431 Thu Mar  2 15:33:12 2000  Greg J. Badros  <gjb@cs.washington.edu>
2432
2433         * hashtab.c: Improved documentation for lots of functions.  Added
2434         handwritten docs for `hash-fold'.
2435
2436 Thu Mar  2 15:13:25 2000  Greg J. Badros  <gjb@cs.washington.edu>
2437
2438         * list.c: Added hand-written docs for `del{q,v,ete}1!'.

2440 Thu Mar  2 12:38:30 2000  Greg J. Badros  <gjb@cs.washington.edu>
2441
2442         * list.c: Moved append docs to append! Thanks Dirk Hermann.  Also,
2443         added append docs from R4RS.
2444
2445         * strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
2446         Thanks Dirk Hermann!
2447
2448         * chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
2449         deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR.  Thanks Dirk Hermann!
2450
2451         * *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
2452         Drop use of SCM_P for function prototypes... assume an ANSI C
2453         compiler.  Thanks Dirk Hermann!

2455 Sat Feb 19 12:20:12 2000  Greg J. Badros  <gjb@cs.washington.edu>
2456
2457         * ports.c: Made `set-port-column!' and `set-port-line!' each
2458         return SCM_UNSPECIFIED instead of a (not-scheme-object) integer
2459         that caused a seg fault.  Also fixed `set-port-column!'s
2460         docstring.  Thanks Han-Wen Nienhuys for finding the bug!

2465         regex-posix.c, scmsigs.c, stime.c, strings.c, variable.c, stime.c,
2466         strings.c, variable.c:  Added lots of documentation, cleaned up
2467         some existing documentation.  Occasionally changed formal params
2468         to match docs.  Also folded an #ifdef into the inners of a
2469         primitive instead of having two copies of the primitive
2470         (`get-internal-real-time', from stime.c)

2472 Sun Feb 13 18:12:19 2000  Greg J. Badros  <gjb@cs.washington.edu>
2473
2474         * ports.c: Added docs for primitives missing them.  Written by
2475         hand.
2476
2477 Sun Feb 13 09:40:36 2000  Greg J. Badros  <gjb@cs.washington.edu>
2478
2479         * guile-doc-snarf.in: Use ${AWK} -f guile-func-name-check, not
2480         just execing guile-func-name-check.  Thanks Michael Livshin!
2481
2482 Thu Feb 10 11:43:23 2000  Greg J. Badros  <gjb@cs.washington.edu>
2483
2484         * guile-snarf.awk.in: Tweak to work with Sun/HP awk, removed some
2485         dead code.  Patch from Michael Livshin.
2486
2487         * guile-doc-snarf.in: Tweak to work with Sun/HP sh.  Patch from
2488         Michael Livshin.
2489
2490 2000-02-09  Gary Houston  <ghouston@arglist.com>
2491
2492         * init.c (scm_init_standard_ports): when stdout is a tty, make the
2493         current-output-port unbuffered by default.  this is less confusing
2494         for interactive use.  it was line-buffered because of a
2495         performance problem with unbuffered ports, but I think it will be
2496         OK now.
2497
2498 2000-02-08  Gary Houston  <ghouston@arglist.com>
2499
2500         * __scm.h: don't define long_long or ulong_long if HAVE_LONG_LONGS
2501         is not defined.
2502
2503         * stime.c (scm_localtime, scm_mktime): if neither HAVE_TM_ZONE nor
2504         HAVE_TZNAME are defined, use an empty string instead of giving two
2505         spurious compile-time errors.
2506
2507 Tue Feb  8 13:57:46 2000  Greg J. Badros  <gjb@cs.washington.edu>
2508
2509         * ports.c: Doc patches from Richard Kim.  Pasted from MIT Scheme.
2510         Thanks Richard!
2511
2512 Mon Feb  7 09:07:31 2000  Greg J. Badros  <gjb@cs.washington.edu>
2513
2514         * macros.c: Doc patches from Richard Kim.  Pasted from scm.texi.
2515
2516 Sun Feb  6 20:26:21 2000  Greg J. Badros  <gjb@cs.washington.edu>
2517
2518         * pairs.c: Doc patches from Richard Kim.  Pasted from MIT Scheme
2519         (which is GNU GPL'd).
2520
2521 2000-01-31  Gary Houston  <ghouston@arglist.com>
2522
2523         * strings.h: don't use SCM_P.  don't include <string.h>.
2524         * error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>.
2525
2526         * strings.c (scm_string_ref): make the 2nd argument compulsory.
2527         previously it defaulted to zero for no good reason that I can see.
2528         use a local variable for SCM_INUM (k).  replace
2529         SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
2530
2531         (scm_makfromstr): cosmetic changes.
2532
2533         (scm_string): Accept only chars in the list, not strings, for
2534         conformance to R5RS (particularly for list->string, which is
2535         supposed to be the inverse of string->list.)  remove
2536         SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
2537         scm_makstr handles the cell allocation.  when reporting wrong-type
2538         arg, don't report the position as 1.
2539
2540         * posix.c (scm_init_posix): intern PIPE_BUF if it's defined.
2541
2542 2000-01-29  Gary Houston  <ghouston@arglist.com>
2543
2544         * posix.c (scm_pipe): rewrote the docstring.
2545
2546         * filesys.c (scm_select, retrieve_select_type, get_element,
2547         fill_select_type, set_element): modified so that Scheme
2548         "select" tests port buffers for the ability to provide input
2549         or accept output.  Previously only the underlying file descriptors
2550         were checked.  Rewrote the docstring.
2551
2552 Thu Jan 27 10:14:25 2000  Greg J. Badros  <gjb@cs.washington.edu>
2553
2554         * vectors.c, symbols.c, strorder.c: Documentation cut and pasted
2555         from Gregg Reynolds.  Thanks Gregg!
2556
2557 Thu Jan 27 09:59:38 2000  Greg J. Badros  <gjb@cs.washington.edu>
2558
2559         * strop.c (scm_i_index): Obfuscated commented-out SCM_DEFINE by
2560         adding "x" prefix to the line so that guile-func-name-check
2561         doesn't complain unnecessarily.
2562
2563 Wed Jan 26 17:33:52 2000  Greg J. Badros  <gjb@cs.washington.edu>
2564
2565         * throw.c: Factor out an #ifdef/#else/#endif choice more finely
2566         for maintainability.
2567
2568         * strop.c: Documentation added by Gregg A. Reynolds.   Pasted in
2569         from qdocs, RnRs.
2570
2571 Wed Jan 26 10:02:11 2000  Greg J. Badros  <gjb@cs.washington.edu>
2572
2573         * tag.c:  Added doc for `tag', but mark as deprecated since Mikael
2574         suggests removing tag.c altogether (and using a new `class-of'
2575         instead).
2576
2577         * strings.c:  Added documentation from Gregg A. Reynolds.  Edited
2578         a bit by me to use FOO instead of @var{foo} and to have the
2579         summary come before preconditions on input.  Also dropped trailing
2580         (rnrs) note.
2581
2582         * gsubr.c: Do not use SCM_DEFINE for `gsubr-apply'. Register the
2583         function with scm_make_subr_opt w/ last arg of 0 so it is not
2584         visible at the Scheme level. Mikael says that this is the right
2585         thing because the first arg to the proc is the guts of a compiled
2586         closure and shouldn't be exposed to the Scheme level.
2587
2588 Tue Jan 25 17:15:47 2000  Greg J. Badros  <gjb@cs.washington.edu>
2589
2590         * sort.c: typo in comment fixed.
2591
2592         * keywords.c: Added documentation.
2593
2594         * guardians.c: Added documentation (could be better).
2595
2596         * gc.c: Added docs for gc-set-debug-check-freelist.
2597
2598         * eq.c: Added docs for eq?, eqv? equal? abridged from R4RS.
2599
2600         * boolean.c: Added docs for `not', `boolean?' (by hand).
2601
2602 Tue Jan 25 13:28:56 2000  Greg J. Badros  <gjb@cs.washington.edu>
2603
2604         * random.c: Added documentation, from SLIB page:
2605         http://angela.ctrl-c.liu.se/~calle/scheme/slib_toc.html
2606
2607 Mon Jan 24 17:50:20 2000  Greg J. Badros  <gjb@cs.washington.edu>
2608
2609         * variable.c, version.c:  Added documentation, written by hand
2610         since I could not find anything already written that was
2611         relevant.
2612
2613 2000-01-23  Gary Houston  <ghouston@arglist.com>
2614
2615         * filesys.c (scm_chown): omit port/fdes support if HAVE_FCHOWN is
2616         not defined (thanks to Richard Y. Kim).
2617
2618 Thu Jan 20 13:00:38 2000  Greg J. Badros  <gjb@cs.washington.edu>
2619
2620         * Makefile.in: Removed, this is auto-generated.
2621
2622 Thu Jan 20 11:33:47 2000  Dirk Hermann <dirk@ida.ing.tu-bs.de> --applied 01/20/00 gjb
2623
2624         * list.c: Put some variable initialization code at the point of
2625         declaration; Added a comment for list*; Formatting changes.
2626
2627         * load.c: use SCM_NNULLP to make sure the end of a list is not
2628         reached yet.
2629
2630 2000-01-18  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
2631
2632         * backtrace.c (scm_display_error_message): Bugfix: Don't use
2633         result of scm_list_p as C boolean.
2634         (scm_display_error_message, scm_set_print_params_x): Use new
2635         validation macros. (Thanks to Dirk Herrmann.)
2636
2637         * net_db.c (scm_resolv_error): Cast result from hstrerror.
2638
2639         * strports.c (st_end_input): Inserted parenthesis to get operator
2640         grouping correct.
2641
2642         * list.h (scm_init_list): Removed SCM_P around prototypes.
2643
2644         * fports.c, list.c, numbers.c, ports.c, stime.c, symbols.c,
2645         filesys.c, posix.c: Converted docstrings to ANSI C format and
2646         escaped " occurring inside string literals.

2652 2000-01-18  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
2653
2654         * alist.c, chars.c, debug.c, dynl.c, dynwind.c, error.c, eval.c,

2663         * filesys.c (scm_chmod), simpos.c (scm_system), version
2664         (scm_version), vports (scm_make_soft_port): Escape " occuring
2665         inside docstring.

2667 Mon Jan 17 11:41:22 2000  Greg J. Badros  <gjb@cs.washington.edu>
2668
2669         * scm_validate.h: Added SCM_VALIDATE_ULONG_COPY,
2670         SCM_VALIDATE_LONG_COPY
2671
2672         * numbers.c: Use SCM_VALIDATE_ULONG_COPY, instead of
2673         SCM_VALIDATE_INUM_COPY to let bigger numbers be used.  Rename a
2674         couple of formal arguments (and fix their uses) to make arguments
2675         match the documentation.
2676
2677 2000-01-14    <mstachow@alum.mit.edu>
2678
2679         * Makefile.am: Augment path when running guile-doc-snarf so
2680         guile-func-name-check is found.
2681
2682 Fri Jan 14 09:34:55 2000  Greg J. Badros  <gjb@cs.washington.edu>
2683
2684         * scm_validate.h (SCM_NUM2LONG_DEF): Fix this macro to just use
2685         def, not SCM_MAKINUM(def);  thanks Janis Bzerins!
2686
2687 Wed Jan 12 00:06:53 2000  Greg J. Badros  <gjb@cs.washington.edu>
2688
2689         * net_db.c (s_scm_inet_makeaddr): Use SCM_NUM2ULONG since that's
2690         the way guile-1.3.4 worked, but #if 0 out the version using
2691         SCM_VALIDATE_INUM_COPY for stricter testing.
2692
2693 Tue Jan 11 18:24:18 2000  Greg J. Badros  <gjb@cs.washington.edu>
2694
2695         * guile-doc-snarf.in: Use new $fullfilename for running
2696         guile-func-name-check, and put "$fullfilename" and "$filename" in
2697         quotes at uses to make sure re-splitting on whitespace does not
2698         occur (so filenames w/ embedded whitespace would work okay, though
2699         I sure hope we never have to deal with that! :-) ).  Thanks to
2700         Mikael for pointing out the source_dir != build_dir was broken.
2701
2702 Tue Jan 11 17:42:40 2000  Greg J. Badros  <gjb@cs.washington.edu>
2703
2704         * scm_validate.h: Added SCM_NUM2LONG_DEF macro.  Make
2705         SCM_OUT_OF_RANGE use SCM_MAKINUM, not scm_long2num.  Added
2706         SCM_COERCE_ROSTRING macro.  Added SCM_VALIDATE_NONEMPTYLIST
2707         macro.  Fix SCM_VALIDATE_STRINGORSUBSTR macro to not use SLOPPY
2708         variants.
2709
2710         * ports.c (scm_port_closed_p): Validate that the arg is a PORT,
2711         then return whether it's an open port (was validating that it was
2712         an open port -- this was a bug I introduced back in December, but
2713         my careful reading of diffs caught it).
2714
2715         * numbers.c: Recombine the two conditional-compilation paths for
2716         all the log* primitives -- they were split based on #ifndef
2717         scm_long2num;  factored out a SCM_LOGOP_RETURN macro, and fixed
2718         some bugs and inconsistencies in the two sets of implementations.
2719         (scm_lognot) Fixed *atrocious* re-use of a SCM as an integer!
2720
2721         * ioext.c: Use SCM_ASSERT_RANGE in a couple places, and
2722         SCM_VALIDATE_INUM_COPY once where it should've been used.
2723
2724         * fluids.c (scm_internal_with_fluids): Use
2725         SCM_VALIDATE_LIST_COPYLEN.
2726
2727         * filesys.c: Use SCM_NUM2LONG instead of SCM_VALIDATE_INUM_COPY;
2728         this is questionable as it relaxes type safety, but other changes
2729         were useful and all SCM_NUM2LONG's should probably be
2730         revisited. Use SCM_OUT_OF_RANGE, SCM_WRONG_TYPE_ARG.
2731
2732         * evalext.c: line-break change on 1 line.
2733
2734         * eval.c (nconc2last): Takes a non-empty list as its first
2735         argument, not just a list.
2736
2737         * dynl.c: Use new SCM_COERCE_ROSTRING macro.
2738
2739 Tue Jan 11 15:44:23 2000  Greg J. Badros  <gjb@cs.washington.edu>
2740
2741         * dynl.c, feature.c, filesys.c, fports.c, list.c, load.c,
2742         net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
2743         where possible.
2744
2745         * symbols.c (scm_sysintern0): Fixed the function name in a
2746         scm_misc_error invocation.
2747
2748         * print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
2749         use scm_return_first to ward off latent GC bug that Mikael caught.
2750
2751         * async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
2752         used before but should've been.
2753
2754 2000-01-12  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
2755
2756         * snarf.h (SCM_PROC1): Replaced SCM (*) (...) with
2757         SCM_FUNC_CAST_ARBITRARY_ARGS.
2758
2759 Tue Jan 11 13:44:07 2000  Greg J. Badros  <gjb@cs.washington.edu>
2760
2761         * guile-func-name-check.in: Added this script to statically check
2762         #define FUNC_NAME, #undef FUNC_NAME in the source.
2763
2764         * sort.c, posix.c: Fix #undef FUNC_NAME lines to not have trailing
2765         redundant comment, semicolon; caught by new guile-func-name-check
2766         script.
2767
2768         * debug.c: Fix mistaken #define FUNC_NAME for scm_make_iloc.
2769         Caught by new guile-func-name-check-script.
2770
2771         * Makefile.am: Added guile-func-name-check to bin_SCRIPTS
2772
2773         * ramap.c: Fix #if 0'd out code to be syntactically acceptable to
2774         guile-func-name-check.
2775
2776         * guile-doc-snarf.in: Run guile-func-name-check on the file before
2777         doing the snarf.
2778
2779 Tue Jan 11 11:31:10 2000  Greg J. Badros  <gjb@cs.washington.edu>
2780
2781         * fports.c, ports.c, ports.h, strports.c, vports.c: Make write
2782         port function take const void*, not void*.
2783
2784 Tue Jan 11 11:18:07 2000  Greg J. Badros  <gjb@cs.washington.edu>
2785
2786         * scm_validate.h, chars.c, ports.c, print.c, read.c, strings.c,
2787         strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
2788         SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY.  Change made for
2789         consistency with the other macros dealing with immediate
2790         characters.  (Similar to INT -> INUM change a week or so ago).
2791
2792 Tue Jan 11 10:41:46 2000  Greg J. Badros  <gjb@cs.washington.edu>
2793
2794         * dynl.c, error.c, eval.c, feature.c, filesys.c, fports.c, list.c, load.c,
2795         net_db.c, read.c, socket.c: Update error messages to use ~A for
2796         %s, ~S for %S to work with new `simple-format' format and be
2797         standardized better.
2798
2799         * print.h, print.c (scm_simple_format): Added `simple-format'
2800         primitive.  It's the old scm_display_error, with ARGS now a rest
2801         parameter, and the destination first instead of last (and a couple
2802         new capabilities inspired by `format' -- #t as destination means
2803         current-output-port, #f means return the formatted text as a
2804         string.
2805
2806         * gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
2807
2808         * backtrace.c (scm_display_error_message): Rewrote to use
2809         scm_simple_format() procedure.
2810
2811         * __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
2812
2813 2000-01-09  Marius Vollmer  <mvo@zagadka.ping.de>
2814
2815         Finally applied the libltdl patch from Thomas Tanner, with slight
2816         modifications.
2817
2818         * DYNAMIC-LINKING: Removed because it is obsolete.
2819         * dynl.c: Use ANSI prototypes.
2820         (sysdep_dynl_link): Use lt_dlopenext instead of lt_dlopen.
2821         * scmconfig.h.in: Do not change, as it is automatically generated.
2822
2823     1999-07-25  Thomas Tanner  <tanner@ffii.org>
2824
2825             * dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c: deleted
2826             (obsolete)
2827             * Makefile.am: likewise, add INCLTDL (libltdl headers) to
2828             INCLUDES, set dlpreopened files in LDFLAGS, link libguile
2829             against libltdl
2830             * dynl.c: use libltdl if DYNAMIC_LINKING is enabled,
2831             * guile.c: register preloaded modules
2832             * scmconfig.h.in: remove obsolete symbols
2833
2834 2000-01-09  Gary Houston  <ghouston@arglist.com>
2835
2836         * These changes should make it unnecessary to call tzset from
2837         Scheme after modifying the TZ environment variable, even if the
2838         system date facilities cache the value.
2839         * stime.c (setzone, scm_localtime): added comments.
2840         (tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
2841         (setzone): don't call tzset.
2842         (restorezone): call tzset only if HAVE_TZSET is defined.
2843         (scm_tzset): don't define if HAVE_TZSET not defined.  Change the
2844         doc string to indicate that this procedure isn't likely to do
2845         anything useful.
2846         (scm_localtime, scm_strftime, scm_mktime): call tzset if
2847         LOCALTIME_CACHE is defined.
2848
2849 2000-01-09  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
2850
2851         * posix.c (scm_sync): Return SCM_UNSPECIFIED.
2852
2853 2000-01-09  Gary Houston  <ghouston@arglist.com>
2854
2855         * eval.c: define scm_unbound_variable_key ('unbound-variable).
2856         scm_lookupcar1: throw an error with key 'unbound-variable instead
2857         of 'misc-error when an unbound variable is encountered.
2858
2859         * filesys.c (scm_mkdir, scm_rmdir, scm_getcwd, scm_select,
2860         scm_symlink, scm_readlink, scm_lstat),
2861         posix.c (scm_setpgid, scm_setsid, scm_ctermid, scm_tcgetpgrp,
2862         scm_tcsetpgrp, scm_uname, scm_setlocale, scm_mknod, scm_nice,
2863         scm_sync),
2864         simpos.c (scm_system),
2865         stime.c (scm_times, scm_strptime):
2866         move the HAVE_XXX feature tests out of the procedure bodies.
2867         don't use SCM_SYSMISSING.
2868         scm_validate.h (SCM_SYSMISSING): removed.
2869         error.h, error.c (scm_sysmissing): comment that this is deprecated.
2870         see ChangeLog entry for 1999-12-28.
2871
2872 Sat Jan  8 19:52:04 2000  Greg J. Badros  <gjb@cs.washington.edu>
2873
2874         * scm_validate.h (SCM_VALIDATE_BOOL_COPY): Fix typo.
2875
2876 Sat Jan  8 17:06:46 2000  Greg J. Badros  <gjb@cs.washington.edu>
2877
2878         * backtrace.c: Fix spelling typo in a comment.
2879
2880         * snarf.h: Use new SCM_DOCS macro to encapsulate the non SCM_INIT
2881         text.  Reformatted some of the expansions.
2882
2883 Fri Jan  7 15:50:46 2000  Greg J. Badros  <gjb@cs.washington.edu>
2884
2885         * scm_validate.h (SCM_OUT_OF_RANGE): Use scm_out_of_range_pos to
2886         report the position of the argument.
2887
2888         * error.h, error.c (scm_out_of_range_pos):  Added this function to
2889         take extra "pos" argument, the position number of the errant
2890         argument.
2891
2892         * debug.c: Use SCM_OUT_OF_RANGE instead of scm_out_of_range.
2893
2894         * snarf.h: Use SCM_HERE and SCM_INIT as names, not SCM_NOTSNARF
2895         and SCM_SNARFING.  Also put the %%% in the SCM_INIT since Mikael
2896         prefers that and I'm reasonably indifferent.
2897
2898 Fri Jan  7 15:03:32 2000  Greg J. Badros  <gjb@cs.washington.edu>
2899
2900         * snarf.h: Factor out differences between C++ and non-C++ into
2901         SCM_FUNC_CAST_ARBITRARY_ARGS macro.  Modify all the snarf macro
2902         definitions to use SCM_NOTSNARF and SCM_SNARFING macros (like
2903         Mikael's macros, below, but changed names and SCM_SNARFING no
2904         longer expands to include %%% -- that must appear in the argument
2905         so that the token appears at the call-site as a reminder).
2906
2907 2000-01-07  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
2908
2909         * snarf.h (SCM_INSITU, SCM_INIT): New snarf macros for use in user
2910         snarf macro definitions.
2911
2912 2000-01-06  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
2913
2914         * chars.c (scm_integer_to_char): Use Greg's nice
2915         SCM_VALIDATE_INUM_RANGE macro for argument checking for closer
2916         adherence to R5RS.
2917
2918 Thu Jan  6 11:48:49 2000  Greg J. Badros  <gjb@cs.washington.edu>
2919
2920         * *.c, snarf.h: Replace GUILE_PROC1 with SCM_DEFINE1 throughout.
2921
2922 Thu Jan  6 11:22:53 2000  Greg J. Badros  <gjb@cs.washington.edu>
2923
2924         * Makefile.am (ETAGS_ARGS): Switch to SCM_DEFINE, SCM_DEFINE1
2925         instead of GUILE_PROC.
2926
2927 Thu Jan  6 11:21:49 2000  Greg J. Badros  <gjb@cs.washington.edu>
2928
2929         * alist.c: Do not report mismatch errors on some uses of `tmp' (do
2930         this by using SCM_ARG2 instead of `2' in the SCM_VALIDATE_CONS
2931         macro call.
2932
2933 Thu Jan  6 09:54:33 2000  Dirk Herrmann <dirk@ida.ing.tu-bs.de> --gjb applied
2934
2935         * scm_validate.h: Remove some redundant NIMP tests.
2936
2937         * alist.c: minimize scope of the tmp variables, and initialize
2938         them when declared. The strange SCM_NIMP tests are replaced by
2939         SCM_CONSP tests that more closely reflect the intended semantics.
2940         However, we don't get a performance penalty here, because the
2941         SCM_CONSP test was performed by the ALISTCELL test anyway.  * The
2942         extremely ugly use of ASRTGO macros was removed: The calls to
2943         ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a
2944         label parameter that only exists when SCM_RECKLESS is not defined.
2945         This works, because ASRTGO itself is defined in a way that it only
2946         makes use of the label parameter if SCM_RECKLESS is not defined
2947         (shudder!).  Does guile make at all use of the possibility to
2948         define SCM_RECKLESS?  * Codesize is likely to be reduced, since
2949         instead of two calls to SCM_ASSERT performed by the ALISTCELL test
2950         we now only get one test.
2951
2952         * list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate.  Also use
2953         SCM_NULLP instead of SCM_IMP.  Drop use of "register" keyword on
2954         some variables in `list?'.  Fix `reverse' and `reverse!'
2955         primitives to handle improper lists better.
2956
2957 Wed Jan  5 11:24:53 2000  Greg J. Badros  <gjb@cs.washington.edu>
2958
2959         * *.[ch]: Whitespace changes -- added space after SCM_VALIDATE_*
2960         macros and SCM_DEFINE macros to match GNU coding standards.
2961
2962 Wed Jan  5 11:04:24 2000  Greg J. Badros  <gjb@cs.washington.edu>
2963
2964         * *.[ch]: Replace GUILE_PROC w/ SCM_DEFINE.
2965
2966 Wed Jan  5 10:59:06 2000  Greg J. Badros  <gjb@cs.washington.edu>
2967
2968         * *.[ch]:  Replace SCM_VALIDATE_INT w/ SCM_VALIDATE_INUM for
2969         better consistency with the names of other SCM_VALIDATE_ macros
2970         and better conformance to guile naming policy.
2971
2972 Wed Jan  5 10:50:39 2000  Greg J. Badros  <gjb@cs.washington.edu>
2973
2974         * ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a
2975         SCM_VALIDATE instead of 1 to avoid a check on the argument (since
2976         it's not the actual name of the formal).
2977
2978         * guile-snarf.awk.in: Do argument/number mismatch checking and
2979         print warnings in an Emacs compile-mode parseable format.
2980
2981         * struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/
2982         SCM_OUTOFRANGE as 3rd argument.
2983
2984         * random.c: Fix argument/number mismatch (that I introduced :-( ).
2985
2986         * __scm.h: Do not #define SCM_ARG* when snarfing;
2987         lets us distinguish between 1 and SCM_ARG1 when snarfing as only
2988         the former (using the number) requires the argument to match the
2989         formal in the current argument snarfing check.
2990
2991         * snarf.h: Give new definition of SCM_ASSERT when in
2992         snarfing mode to output a lexically-identifiable sequence that the
2993         guile-snarf.awk script uses to verify argument/position matching.
2994
2995         * ramap.c: Remove extraneous #undef FUNC_NAME.
2996
2997 Wed Jan  5 08:36:38 2000  Greg J. Badros  <gjb@cs.washington.edu>
2998
2999         * guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the
3000         current version of the same functionality; it writes the .x output
3001         to stdout instead of directly into the file.
3002
3003 Wed Jan  5 08:15:04 2000  Greg J. Badros  <gjb@cs.washington.edu>
3004
3005         * unif.c, symbols.c, strings.c, stacks.c, random.c, print.c,
3006         posix.c:  Eliminated a bunch of SCM_NIMP(..)s that are now
3007         redundant with the safer macros.  Patch from Dirk Hermann applied
3008         by hand. Thanks Dirk!
3009
3010         * scm_validate.h: Added SCM_VALIDATE_VECTOR_OR_DVECTOR for some
3011         uses in random.c.
3012
3013         * ramap.c: whitespace change.
3014
3015 Tue Jan  4 14:21:35 2000  Greg J. Badros  <gjb@cs.washington.edu>
3016
3017         * options.c, objects.c, keywords.c, gc.c: Some redundant SCM_NIMP
3018         removals from Dirk Hermann.
3019
3020         * alist.c: Rename formals to match the parameter names in the
3021         documentation, updates to documentation.  Thanks Dirk Hermann!
3022
3023 2000-01-04  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
3024
3025         * eval.c (SCM_CEVAL): Reverse order of
3026         scm_stack_checking_enabled_p and SCM_STACK_OVERFLOW_P
3027         (Thanks to Brad Knotwell.)
3028
3029 Mon Jan  3 08:30:02 2000  Greg Harvey  <Greg.Harvey@thezone.net> (applied --01/03/00 gjb)
3030
3031         * gc.c (scm_debug_newcell): Added SCM_SETCAR of the newly
3032         allocated cell.
3033
3034         * pairs.h: Added a comment about the need for the SCM_SETCAR in
