libguile/ChangeLog

   1 2000-03-31  Dirk Herrmann  <D.Herrmann@tu-bs.de>
   2
   3         * ports.h (scm_port):  Change type of stream member to scm_bits_t.
   4
   5         * gdbint.c (unmark_port, remark_port), ports.c (scm_markstream),
   6         strports.c (st_resize_port, scm_mkstrport), vports (sf_flush,
   7         sf_write, sf_fill_input, sf_close, scm_make_soft_port):  Since
   8         streams are now of type scm_bits_t, SCM streams have to be
   9         unpacked/packed.
  10
  11         * ports.h (SCM_SETPTAB_ENTRY, SCM_SETSTREAM):  Cast input to
  12         scm_bits_t.
  13
  14 2000-03-31  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
  15
  16         * coop-defs.h (struct coop_t): Added `sto'-field again because of
  17         binary compatibility---let's remove it next time we alter some
  18         major structure.
  19
  20         * coop.c (coop_quitting_p, coop_cond_create, coop_mutex_create,
  21         coop_mother, coop_child): New variables.
  22         (mother): New function.
  23         (coop_create): New thread spawning mechanism which uses a "mother
  24         thread".  The "dummy" pthreads aren't healthy enough to give birth
  25         to new threads since Linux threads thinks they are asleep.
  26
  27         * coop-defs.h (struct coop_t): Removed dummy_mutex.
  28
  29         * coop-defs.h, coop-threads.c (struct coop_t): Eliminate
  30         `sto'-field when GUILE_PTHREAD_COMPAT is enabled.
  31
  32 2000-03-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>
  33
  34         * arbiters.c (scm_make_arbiter), async.c (scm_async), dynwind.c
  35         (scm_internal_dynamic_wind):  Smob data is always of type
  36         scm_bits_t.
  37
  38         * arbiters.c (SCM_ARB_LOCKED, SCM_LOCK_ARB, SCM_UNLOCK_ARB):
  39         Access the locking information in cell entry 0 with
  40         SCM_{SET_}?CELL_WORD_0 instead of SCM_*CAR.
  41
  42         * async.c (scm_run_asyncs):  Use SCM_NULLP to test for the empty
  43         list.
  44
  45         * dynwind.c (scm_dowinds):  Use SCM_EQ_P to compare SCM values.
  46
  47         * ports.h (SCM_PTAB_ENTRY, SCM_SETPTAB_ENTRY):  Access the ptab
  48         entry data using SCM_{SET_}?CELL_WORD_1 instead of SCM_{SET}?CDR.
  49
  50 2000-03-29  Dirk Herrmann  <D.Herrmann@tu-bs.de>
  51
  52         * alist.c (scm_sloppy_assq, scm_assq), eq.c (scm_eq_p, scm_eqv_p,
  53         scm_equal_p), list.c (scm_ilength, scm_last_pair, scm_reverse,
  54         scm_sloppy_memq, scm_delq_x, scm_delq1_x), tags.h (SCM_UNBNDP):
  55         Don't use C operators == and != to compare SCM values, use
  56         SCM_EQ_P instead.
  57
  58         * boolean.c (scm_boolean_p):  Use SCM_BOOLP to determine whether a
  59         SCM value is equal to #t or #f.
  60
  61         * eq.c (scm_eqv_p, scm_equal_p):  Don't use SCM_CAR to access the
  62         cell type entry of non immediate objects of unknown type.  Use
  63         SCM_CELL_TYPE instead.
  64
  65         * gh_data.c (gh_scm2bool, gh_module_lookup), list.c
  66         (scm_sloppy_memv, scm_sloppy_member, scm_delv_x, scm_delete_x,
  67         scm_delv1_x, scm_delete1_x), scmsigs.c (scm_sigaction):  Use
  68         SCM_FALSEP and SCM_TRUE_P to compare SCM values against #f and
  69         #t.
  70
  71         * list.c (scm_listify):  Use SCM_UNBNDP to test for an unbound
  72         scheme value.
  73
  74 2000-03-29  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
  75
  76         * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread,
  77         scm_make_mutex, scm_make_condition_variable): Cast data to
  78         scm_bits_t in SCM_SET_CELL_WORD and SCM_NEWSMOB macros.
  79
  80         * coop.c (coop_create): Set `specific' field, not `data' to NULL.
  81
  82 2000-03-29  Dirk Herrmann  <D.Herrmann@tu-bs.de>
  83
  84         * smob.h (SCM_NEWSMOB, SCM_NEWSMOB2, SCM_NEWSMOB3, SCM_SMOB_DATA,
  85         SCM_SET_SMOB_DATA, SCM_TC2SMOBNUM, SCM_SMOBNUM):  To access smob
  86         data, use SCM_{SET_}?CELL_TYPE or SCM_{SET_}?WORD_[1-3].
  87
  88         Note that this implies that smob data has always to be passed as
  89         values of type scm_bits_t.
  90
  91 2000-03-29  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
  92
  93         * threads.c (scm_init_threads): Pass 0 size to scm_make_smob_type
  94         for scm_tc16_thread.  As the current COOP threads are written, GC
  95         is not supposed to manage storage for threads.
  96
  97         * error.c (scm_error): Don't try to throw an error if
  98         scm_gc_heap_lock is true.
  99
 100         * coop.c (coop_finish): New function.  Called at exit.
 101         (coop_aborthelp): Free thread structures when threads die.
 102         Finished LinuxThreads compatibility support => COOP threads now
 103         mesh with LinuxThreads.
 104
 105         * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread):
 106         Changed SETCDR --> SET_CELL_WORD_1.
 107
 108         * coop-threads.c (scheme_launch_thread): Set word 1 of handle to 0
 109         when thread dies.
 110
 111 2000-03-29  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 112
 113         * boolean.h (SCM_TRUE_P):  New macro.
 114
 115         * boolean.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOLP), pairs.h
 116         (SCM_NULLP, SCM_NNULLP):  Use SCM_EQ_P to compare SCM values.
 117
 118 2000-03-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 119
 120         * continuations.h (SCM_CONTREGS, SCM_SET_CONTREGS):  New macros to
 121         access continuation data.
 122
 123         (SCM_SETJMPBUF):  Deprecated.  Use SCM_SET_CONTREGS instead.
 124
 125         (SCM_JMPBUF, SCM_DYNENV, SCM_THROW_VALUE, SCM_BASE, SCM_SEQ,
 126         SCM_DFRAME):  Use SCM_CONTREGS instead of SCM_CHARS to access
 127         continuation data.
 128
 129         * continuations.c (scm_make_cont), init.c (start_stack),
 130         root.c (scm_internal_cwdr):  Use SCM_SET_CONTREGS instead of
 131         SCM_SETJMPBUF.
 132
 133 2000-03-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 134
 135         * symbols.h (SCM_LENGTH, SCM_SETLENGTH):  Access the length field
 136         of strings and symbols by using SCM_{SET_}?CELL_WORD_0.
 137
 138         (SCM_CHARS, SCM_UCHARS, SCM_SETCHARS):  Use SCM_{SET_}?CELL_WORD_1
 139         to access the char * field of strings and symbols.
 140
 141 2000-03-27  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 142
 143         * gc.h (SCM_NEWCELL, SCM_NEWCELL2):  Use SCM_SET_CELL_TYPE to set
 144         the type entry of a new cell.  Added a comment about things to
 145         remember when updating the list of free cells.
 146
 147         (SCM_FREEP, SCM_MARKEDP):  Use SCM_CELL_TYPE to access the type
 148         entry of a cell.
 149
 150 2000-03-27  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 151
 152         * pairs.h (SCM_CAR, SCM_CDR, SCM_SETCAR, SCM_SETCDR):  Use
 153         SCM_CELL_OBJECT and SCM_SET_CELL_OBJECT.  This change implies that
 154         with strict type checking enabled these macros will only work if
 155         given valid SCM parameters.
 156
 157         (SCM_GCCDR):  Moved to tags.h.
 158
 159         * tags.h (SCM_GCCDR):  Moved here from pairs.h.
 160
 161 2000-03-26  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 162
 163         * tags.h (SCM2PTR, PTR2SCM):  Moved to gc.h.
 164
 165         * pairs.h (scm_cell, SCM_CELLPTR, SCM_CELL_WORD*, SCM_CELL_OBJECT*,
 166         SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*, SCM_CELL_TYPE,
 167         SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK, SCM_PTR_GT,
 168         SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC, SCM_NEWCELL,
 169         SCM_NEWCELL2):  Moved to gc.h.
 170
 171         (SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR, SCM_SETAND_CDR,
 172         SCM_SETOR_CAR, SCM_SETOR_CDR):  Moved to gc.h.  These names should
 173         be changed, though, since the macros are not only pair related.
 174
 175         (SCMPTR):  Deleted.
 176
 177         * gc.h (SCM2PTR, PTR2SCM, scm_cell, SCM_CELLPTR, SCM_CELL_WORD*,
 178         SCM_CELL_OBJECT*, SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*,
 179         SCM_CELL_TYPE, SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK,
 180         SCM_PTR_GT, SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC,
 181         SCM_NEWCELL, SCM_NEWCELL2, SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR,
 182         SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR):  Moved here from
 183         tags.h and pairs.h.
 184
 185 2000-03-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 186
 187         * tags.h (SCM_STRICT_TYPING):  New macro that, if defined,
 188         activates strict compile time type checking for variables of
 189         type SCM.
 190         (SCM, SCM_PACK, SCM_UNPACK):  Define according to whether
 191         SCM_STRICT_TYPING or SCM_VOIDP_TEST are defined.
 192         (SCM_EQ_P):  Defined as a macro equivalent for eq?.
 193
 194 2000-03-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 195
 196         * tags.h (SCM_POINTERS_MUNGED):  Removed.
 197
 198         * gc.c (scm_gc_sweep, init_heap_seg):  Removed use of
 199         SCM_POINTERS_MUNGED, thus fixing some illegal casts to SCM.
 200
 201 2000-03-24  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 202
 203         * pairs.h (SCM_CELL_OBJECT, SCM_CELL_OBJECT_[0-3],
 204         SCM_SET_CELL_OBJECT, SCM_SET_CELL_OBJECT_[0-3], SCM_CELL_TYPE,
 205         SCM_SET_CELL_TYPE):  Added a set of low level macros for accessing
 206         cell entries.
 207         (SCM_CELL_WORD_[0-3]): Renamed from the SCM_CELL_WORD[0-3].
 208
 209         * procs.h, procs.c:  Instead of SCM_{SET_}?CELL_WORD[12], use the
 210         newly introduced SCM_{SET_}?CELL_OBJECT_[12] macros.
 211
 212 2000-03-23  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 213
 214         * tags.h: Disabled definition of SCM_VOIDP_TEST.
 215
 216         Defining SCM as void * introduces problems which haven't been
 217         handled yet.  Developers who work with these issues can enable it
 218         in their working copies.
 219
 220         Disabling this definition exposes a set of newly introduced and
 221         older misuses of types which causes warning messages during
 222         compilation.  We'll fix this successively.
 223
 224         * gc.c (scm_mark_locations): Changed * (SCM **) X --> * (SCM *) X
 225         in order to obtain a value of type SCM.
 226         (scm_cellp): Updated with new changes to scm_mark_locations.
 227
 228         * continuations.h (SCM_SETJMPBUF): Cast second arg into SCM.
 229
 230         * continuations.c (scm_make_cont): Removed cast of size_t into
 231         long.
 232
 233         * symbols.h (SCM_SETCHARS): Cast second arg into SCM.
 234
 235 2000-03-22  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 236
 237         * numbers.h (SCM_SETNUMDIGS):  Use SCM_BIGSIZEFIELD macro for
 238         shifting, not constant.  Thanks to Dale P. Smith.
 239
 240         * numbers.c (scm_sum, scm_difference):  Don't test a SCM value
 241         for being less than zero.  Decode it to a C value first.  Again,
 242         thank you Dale.
 243
 244 2000-03-22  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 245
 246         * numbers.h, ramap.c, struct.h, vectors.h:  Don't use SCM2PTR for
 247         non scheme values.  If raw data is stored in SCM variables, it has
 248         to be accessed using SCM_UNPACK until a better solution is found.
 249
 250 2000-03-22  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 251
 252         * tags.h (SCM_ECONSP, SCM_NECONSP): More corrections of
 253         pointer-arithmetic induced by the SCM_PACK/UNPACK change.
 254
 255         * print.c (scm_iprin1): SCM_PACK/UNPACK corrections.
 256
 257         * gc.c (scm_gc_sweep): SCM_PACK/UNPACK corrections.
 258
 259         * eval.c (SCM_CEVAL, scm_unmemocar): SCM_PACK/UNPACK corrections.
 260
 261         * dynwind.c (scm_swap_bindings): SCM_PACK/UNPACK corrections.
 262
 263         * async.c, __scm.h: Removed lots of the old async click logic.  It
 264         is possible to reinsert it by defining GUILE_OLD_ASYNC_CLICK in
 265         __scm.h.  Let's try this out and dump the old code after the
 266         threads reorganization.
 267         (set-tick-rate, set-switch-rate): Conditionally removed.
 268
 269 2000-03-21  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 270
 271         * gc.c (scm_gc_mark): Bugfix 1: The recent SCM_PACK/UNPACK change
 272         made SCM values into pointers.  This turned an arithmetic
 273         computation of the address of the vcell into a pointer-arithmetic
 274         one, thereby screwing up marking of structs.
 275         Bugfix 2: Removed incompletely introduced loop variable `j' used
 276         when protecting the tail array of a struct.
 277
 278 2000-03-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 279
 280         * struct.h (SCM_STRUCT_DATA):  Don't cast SCM values to pointers.
 281
 282 2000-03-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 283
 284         * symbols.h, symbols.c (scm_strhash):  Declare the string
 285         parameter as constant, since it is not modified.
 286
 287         * symbols.c (scm_intern_obarray_soft,
 288         scm_sysintern0_no_module_lookup):  Can now pass constant strings
 289         to scm_strhash without need for casting.
 290
 291 2000-03-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 292
 293         * vectors.h (SCM_VELTS, SCM_VELTS_AS_STACKITEMS):  Don't cast SCM
 294         values to pointers.  Use SCM2PTR instead.
 295
 296 2000-03-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 297
 298         * async.c (scm_set_tick_rate, scm_set_switch_rate):  Don't unpack
 299         results of SCM_INUM.
 300
 301 2000-03-21  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 302
 303         * init.c (scm_boot_guile_1): Renamed GUILE_GC_TRIGGER_1 -->
 304         GUILE_MIN_YIELD_1, GUILE_GC_TRIGGER_2 --> GUILE_MIN_YIELD_2.
 305         GUILE_MIN_YIELD_X now take *positive* fractions of heap size.
 306
 307         * gc.c, gc.h (SCM_MIN_YIELD_1, SCM_MIN_YIELD_2,
 308         min_yield_fraction, min_yield, adjust_min_yield): Renamed from
 309         SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2, gc_trigger_fraction,
 310         gc_trigger, adjust_gc_trigger.
 311
 312         * gc.c (alloc_some_heap): Further improvement of minimal heap size
 313         prediction.
 314         (SCM_MAX): New macro.
 315         (scm_freelist_t): New field: collected_1. Previous amount of
 316         collected cells.
 317         (gc_sweep_freelist_finish): Trigger based on two last values of
 318         freelist->collected to avoid unnecessary allocation due to
 319         temporary peaks.
 320         (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2):
 321         Adjusted to 45000 cells, 40% and 40%.  Gives quick startup
 322         without extra heap allocation.
 323
 324 2000-03-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 325
 326         * numbers.h (SCM_MAKINUM):  The parameter to SCM_MAKINUM should
 327         already be a C value.  No need to unpack it.
 328
 329         * numbers.c (scm_long_long2num):  Cast the parameter to scm_bits_t
 330         if we know it fits into an inum.
 331
 332         * ramap.c (ramap_rp):  An scm_tc7_[ui]vect object does point to a
 333         field of long values.  In contrast, SCM_VELTS accesses a field of
 334         SCM values.
 335
 336 2000-03-20  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 337
 338         * gc.c (scm_gc_stats): Inserted explanation of local_scm_mtrigger
 339         etc.
 340         (scm_gc_yield_1): New variable: Holds previous yield.  Used to
 341         make better judgements.
 342         (gc_sweep_freelist_finish): Inserted explanation of use of
 343         gc_trigger.
 344
 345         * print.h, stacks.h, options.c, options.h: Changed C++
 346         commentaries to C.
 347
 348 2000-03-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 349
 350         * tags.h (SCM2PTR, PTR2SCM):  Use SCM_PACK / SCM_UNPACK correctly.
 351
 352         * numbers.h (SCM_INUMP, SCM_MAKINUM, SCM_INUM0, SCM_COMPLEX_REAL,
 353         SCM_COMPLEX_IMAG, SCM_NUMP, SCM_BDIGITS):  Use SCM_PACK /
 354         SCM_UNPACK / SCM2PTR correctly.
 355
 356 2000-03-20  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 357
 358         * gc.c (adjust_gc_trigger): Improved documentation.
 359         (alloc_some_heap): Since gc_trigger is used against
 360         freelist->collected, this is the value which should be used to
 361         predict minimum growth.
 362
 363 2000-03-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 364
 365         * eval.h:  Fix mixup of packed/unpacked SCM values.  (Thanks
 366         Thien-Thi Nguyen for the patch.)
 367
 368 2000-03-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 369
 370         * numbers.c (scm_ash):  Fixed typing problems with the second
 371         parameter and added some documentation.  (Thanks Thien-Thi Nguyen
 372         for indicating the problem.)
 373
 374 2000-03-19  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 375
 376         * gc.c, gc.h (scm_gc_yield): New variable.
 377         (adjust_gc_trigger): Use scm_gc_yield.
 378         (alloc_some_heap): Use scm_gc_yield instead of
 379         scm_gc_cells_collected.
 380
 381         * coop-threads.c: Addd #include "root.h", #include "strings.h".
 382
 383         * debug.c: Added #include "root.h".  (Thanks to Thien-Thi Nguyen.)
 384
 385         * gc.c (scm_gc_for_newcell, adjust_gc_trigger): Improved GC
 386         trigger adjustmeant: Take yield (freed cells) for all freelists
 387         into account.
 388         (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Tuned
 389         to 50000 cell heap with 45% trigger.
 390         (scm_gc_cells_collected): Reintroduced.
 391         (SCM_HEAP_SIZE): New macro.
 392         (scm_gc_sweep): Reintroduced correct computation of
 393         scm_cells_allocated.
 394         (scm_freelist_t): Corrected commentary for field `cluster_size':
 395         Clustersize counts objects, not cells;  New member
 396         `clusters_allocated'.
 397
 398 2000-03-19  Michael Livshin  <mlivshin@bigfoot.com>
 399
 400         * *.[hc]: add Emacs magic at the end of file, to ensure GNU
 401         indentation style.
 402
 403 2000-03-19  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 404
 405         * threads.h: Added #include "libguile/throw.h".  (Thanks to
 406         Thien-Thi Nguyen.)
 407
 408 2000-03-18  Michael Livshin  <mlivshin@bigfoot.com>
 409
 410         * tags.h: (SCM_DOUBLE_CELLP, SCM_NDOUBLE_CELLP): new macros.
 411
 412         * gc.h: (typedef struct scm_freelist_t) remove from here.
 413
 414         * gc.c: (CELL_UP, CELL_DN) make these macros take additional
 415         parameter (the span).
 416         (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK) new macros.
 417         (typedef struct scm_freelist_t) move here from gc.h, it had no
 418         business being externally visible.
 419         (typedef struct scm_heap_seg_data_t) renamed from
 420         scm_heap_seg_data, to be style-compliant.
 421         (scm_mark_locations) if the possible pointer points to a
 422         multy-cell, check that it's properly aligned.
 423         (init_heap_seg) alighn multy-cells properly, work with the
 424         assumption that the segment size divides cleanly by cluster size
 425         (so that there's no spill).
 426         (round_to_cluster_size) new function.
 427         (alloc_some_heap, make_initial_segment) use round_to_cluster_size
 428         to satisfy the new init_heap_seg invariant.

 487 2000-03-17  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 488
 489         * gc.c, gc.h: Cleanup of the change of 2000-03-15.
 490         Cluster sizes are now independent of GC trigger values.
 491         GUILE_GC_TRIGGER_n can now specify a relative trigger value:
 492         A negative integer gives fraction of total heap size in percent.
 493         (SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Default values set to -40.
 494
 495         * init.c (scm_boot_guile_1): Introduced new variable
 496         GUILE_MAX_SEGMENT_SIZE; New environment variable names:
 497         GUILE_INIT_SEGMENT_SIZE_1, GUILE_GC_TRIGGER_1,
 498         GUILE_INIT_SEGMENT_SIZE_2, GUILE_GC_TRIGGER_2
 499
 500 2000-03-16  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 501
 502         * __scm.h (GC_FREE_SEGMENTS): Disable this until we have made
 503         freeing of segment work with the new GC scheme.  (Thanks to
 504         Michael Livshin.)  Oops, also happened to make GUILE_NEW_GC_SCHEME
 505         the default, but I'll let this change stay in CVS Guile since this
 506         code is not expected to contain serious bugs.
 507
 508 2000-03-16  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 509
 510         * gc.c, gc.h (scm_map_free_list): Define also if GUILE_DEBUG is
 511         defined.
 512         (scm_free_list_length): New procedure (GUILE_DEBUG).
 513         Fixed a small but serious bug introduced by the previous change.
 514
 515         * gc.c (scm_gc_sweep): Moved variable n_objects to inner sweep
 516         loop and declare as register.
 517
 518         * gc.c (scm_gc_sweep): Sigh... forgot to clear private freelists
 519         after GC.
 520
 521 Wed Mar 15 08:27:04 2000  Greg J. Badros  <gjb@cs.washington.edu>
 522
 523         * fluids.c: Docstring patch from Keisuke Nishida.  Some
 524         reindentation, too, and a couple formals renamed.  Should
 525         fluid-set! return UNSPECIFIED instead of a value?
 526
 527 Wed Mar 15 08:24:58 2000  Greg J. Badros  <gjb@cs.washington.edu>
 528
 529         * Makefile.am: Separate out DOT_X_FILES and DOT_DOC_FILES, and
 530         generate the latter from the concrete listing of the former.  Then
 531         make guile-procedures.txt depend on DOT_DOC_FILES instead of
 532         *.doc, so that rebuilding it works.
 533
 534 Wed Mar 15 08:12:14 2000  Greg J. Badros  <gjb@cs.washington.edu>
 535
 536         * libguile.h: Include libguile/validate.h.  Thanks Keisuke Nishida!
 537
 538         * guile-snarf.awk.in: Replace docstring line-ending \n" and \n\n"
 539         with nothing and \n, respectively. Thanks Keisuke Nishida for
 540         noticing this problem.
 541
 542 2000-03-15  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 543
 544         * __scm.h (GUILE_NEW_GC_SCHEME): Define this if you want to test a
 545         new way of allocating heap.  It makes Guile fast, but still
 546         contains bugs.
 547
 548         * gc.c, gc.h, pairs.h, init.c: Implementation of a new way of
 549         allocating heap.  The basic idea is to trigger GC every Nth
 550         allocated cell and grow heap when free list runs out.  The scheme
 551         has been extended so that GC isn't triggered until all remaining
 552         cells are used.  The implementation is also prepared for
 553         development in the direction of POSIX threads.
 554
 555         * gc.c (SCM_EXPHEAP): In order to grow by a factor of 1.5,
 556         SCM_EXPHEAP should return half of the heap size.
 557
 558 2000-03-14  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 559
 560         The following change to init.c is only enabled if Guile was
 561         configured with --enable-guile-debug.
 562
 563         * init.c (scm_i_getenv_int): New function.
 564         (scm_boot_guile_1): Use the environment variables
 565         GUILE_INIT_HEAP_SIZE, GUILE_INIT_HEAP_SIZE2 to select heap size if
 566         they exist.  (This may be replaced by a Scheme level mechanism in
 567         the future.)
 568
 569         * objprop.c (s_scm_set_object_property_x): Use scm_assq instead of
 570         scm_assoc.  (Thanks to Keisuke Nishida.)
 571
 572 2000-03-14  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 573
 574         * eval.c, lang.c, lang.h (scm_lisp_nil, scm_lisp_t): Renamed from
 575         scm_nil, scm_t.  (Thanks to Keisuke Nishida.)
 576
 577 2000-03-14  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 578
 579         * init.c (scm_boot_guile_1): Use same initial segment size for
 580         1-word and 2-word segments.  Having the smaller size causes Guile
 581         to GC too often.  Obviously something needs to be done to allow
 582         for a smaller 2-word segment without this to happen.  (The amount
 583         of heap for each type should be automatically adapted to the
 584         application somehow.)
 585
 586         [Almost all of these changes should be documented in the NEWS
 587         file.]
 588
 589         * gc.h (scm_freelist_t): New type.
 590
 591         * pairs.h (SCM_NEWCELL, SCM_NEWCELL2): Use new style freelists.
 592
 593         * gc.c (SCM_INIT_HEAP_SIZE): Changed from 32768 --> 40000 so that
 594         all of Guile basics fits into one segment and there suitable room
 595         for work.
 596         (SCM_EXPHEAP): Now takes an argument.  Grow by a factor of 1.5
 597         instead of 2.
 598         (scm_freelist, scm_freelist2): Now of type scm_freelist_t.
 599         Freelists now contains information about object span, cells
 600         collected and amount of cells in heap segments belonging to the
 601         list.
 602         (scm_heap_size, scm_gc_cells_collected): Removed.
 603
 604         * init.c (scm_boot_guile_1): Make 2-word segment 8K (512 cells).
 605
 606         * Makefile.am (libguile_la_LDFLAGS): Bumped library version
 607         number.
 608
 609         * __scm.h eq.c, eval.c, gc.c, gc.h, gh_data, hash.c, numbers.c,
 610         numbers.h, objects.c, ramap.c, random.c, unif.c, unif.h: Extensive
 611         rewrite of handling of real and complex numbers.
 612         (SCM_FLOATS, SCM_SINGLES): These #ifdef conditionals have been
 613         removed along with the support for floats.  (Float vectors are
 614         still supported.)
 615
 616         * tags.h (scm_tcs_bignums): Removed.
 617         (scm_tc16_bigpos, scm_tc16_bigneg): Replaced by scm_tc16_big.
 618         Use SCM_BIGSIGN(x) to test for sign!
 619         (scm_tc16_big): The new bignum type.
 620         (SCM_REAL_PART, SCM_IMAG_PART): Removed.
 621
 622         * numbers.h (SCM_BIGSIGN): Sign moved to bit 16.
 623         (scm_makdbl): Deprecated.
 624         (SCM_NEWREAL, SCM_NEWCOMPLEX): New macros.
 625         (SCM_SINGP): Deprecated.
 626         (SCM_FLO): Removed.
 627         (SCM_INEXP, SCM_CPLXP): Deprecated.
 628         (SCM_INEXACTP, SCM_COMPLEXP): New macros.
 629         (SCM_COMPLEX_REAL, SCM_COMPLEX_IMAG): Renamed from
 630         SCM_REAL, SCM_IMAG (and now only valid for complex numbers).
 631         (SCM_REAL, SCM_IMAG): New, *deprecated*, selectors which work both
 632         for doubles and complex numbers.
 633         (SCM_REAL_VALUE): New selector for doubles.
 634         (scm_double_t, scm_complex_t): New types.
 635         (scm_dbl): Removed.
 636
 637         * numbers.c (scm_floprint, scm_floequal): Removed.
 638         (scm_print_real, scm_print_complex, scm_real_equalp,
 639         scm_complex_equalp): New functions.
 640
 641         * unif.c (scm_makflo): Removed.
 642
 643         * smob.h (SCM_SMOB_PREDICATE): New macro.
 644         (SCM_NEWSMOB2, SCM_RETURN_NEWSMOB2, SCM_NEWSMOB3,
 645         SCM_RETURN_NEWSMOB3): New macros.
 646
 647 1999-11-21  Michael Livshin  <mlivshin@bigfoot.com>
 648
 649         The following changes implement primitive support for double cells
 650         (i.e. four-word cells) and change the representation of some
 651         things to multi-cells instead of cons+malloc.  (Applied and
 652         modified by mdj.)
 653
 654         * pairs.h (SCM_NEWCELL2): double-cell variants of SCM_NEWCELL.
 655         (SCM_CELL_WORD, SCM_CELL_WORDLOC, SCM_SET_CELL_WORD): primitive
 656         multi-cell access macros (used by the ones below).
 657         (SCM_CELL_WORD[0-3], SCM_SET_CELL_WORD[0-3]): multi-cell access
 658         macros.
 659
 660         * gc.c (scm_freelist2): multi-cell freelists.
 661         (inner_map_free_list): map_free_list, parameterized on ncells.
 662         "nn cells in segment mm" was misleading for ncells > 1; changed to
 663         "objects".  still print cells too, though.
 664         (scm_map_free_list): rewritten using inner_map_free_list.
 665         (scm_check_freelist): get freelist as parameter, since now we have
 666         more than one.
 667         (scm_debug_newcell2): multi-cell variants of
 668         scm_debug_newcell.
 669         (scm_gc_for_newcell): take ncells and freelist pointer as
 670         parameters.
 671         (scm_gc_mark): add case for tc7_pws (procedures with setters are
 672         now double cells).
 673         (scm_gc_sweep): don't free the float data, since it's not malloced
 674         anymore.
 675         (init_heap_seg): didn't understand what n_new_objects stood for,
 676         so changed to n_new_cells.
 677         (make_initial_segment): new function, makes an initial segment
 678         according to given ncells.
 679         (scm_init_storage): call make_initial_segment, for ncells={1,2,3}.
 680
 681         * numbers.c (scm_makdbl): no malloc'ing needed, so the
 682         {DEFER,ALLOW}_INTS thing removed.
 683
 684         * numbers.h (struct scm_dbl): changed to represent a double cell,
 685         with the number in the second half.
 686
 687         * dynwind.c: changed the wind-guards representation to double
 688         cell.
 689
 690         * procs.c, procs.h: changed the procedure-with-setter representation
 691         to double cell.
 692
 693         * async.c, async.h: made async representation a double cell.
 694
 695         * dynl.c: made dynamic_obj representation a double cell.
 696
 697 2000-03-13  Gary Houston  <ghouston@arglist.com>
 698
 699         * ports.c (flush_void_port): renamed to flush_port_default.
 700         (end_input_void_port): renamed to end_input_default.
 701
 702         * init.c (scm_standard_stream_to_port): create a void port instead
 703         of opening /dev/null if the standard file descriptors are bad.
 704         advantages: no portability problems, doesn't waste a file descriptor,
 705         simplifies the code (thanks to Marius for the idea).
 706
 707         * vports.c (s_scm_make_soft_port): call scm_port_non_buffer.
 708
 709         * void ports: make reading from a void port give EOF instead of
 710         segv:
 711         * ports.c (s_scm_sys_make_void_port): modified docstring.
 712         (fill_input_void_port): new proc.
 713         (scm_init_ports): set up fill_input_void_port.
 714         * ports.c (scm_port_non_buffer): new proc.
 715         (scm_void_port): call scm_port_non_buffer.
 716
 717         * fports.c (scm_setvbuf): docstring: remove the fcntl documentation
 718         which was incorrectly appended.
 719
 720 2000-03-13  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 721
 722         * guile-doc-snarf.in: Don't use absolute path for `sed'.  (Note
 723         that we can't use autoconf for this.  Autoconf itself relies on
 724         the existence of `sed' somewhere on your path.)  (Thanks to Dirk
 725         Herrman.)
 726
 727 2000-03-13  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 728
 729         * Makefile.am (libguile_la_SOURCES): Moved iselect.c here from
 730         EXTRA_libguile_la_SOURCES.
 731
 732         * iselect.h: Always declare scm_internal_select.
 733
 734         * iselect.c (scm_internal_select): Added SCM_ASYNC_TICK at the
 735         end.  Also let scm_internal_select be a real function also when
 736         not using threads.
 737
 738         * __scm.h (SCM_TICK): Oops! Forgot to put SCM_ASYNC_TICK here...
 739
 740 2000-03-13  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 741
 742         * __scm.h (SCM_ALLOW_INTS, SCM_REALLOW_INTS): Removed call to
 743         SCM_ASYNC_TICK.  (This is a preparation for POSIX threads support,
 744         and kind of an experiment: Will this cause problems?)
 745
 746 Sun Mar 12 13:26:30 2000  Greg J. Badros  <gjb@cs.washington.edu>
 747
 748         * Makefile.am: Added *.doc to DISTCLEANFILES.
 749
 750 2000-03-12  Gary Houston  <ghouston@arglist.com>
 751
 752         * fports.c (scm_fdes_to_port): call fcntl F_GETFL to test that
 753         the fdes is valid before doing anything else.  check that
 754         the file descriptor supports the modes required.
 755         (scm_fport_buffer_add): don't throw an error if fstat doesn't
 756         work: just use the default buffer size.
 757
 758         * throw.c: change an outdated comment about scm_internal_catch
 759         BODY: it doesn't take a jumpbuf arg.
 760
 761         * init.c (scm_standard_stream_to_port): install a handler in case
 762         scm_fdes_to_port throws an error.  don't check here whether the
 763         file descriptor is valid, since scm_fdes_to_port will do that.
 764         set the revealed count depending on whether the port got the
 765         standard file descriptor.
 766         (stream_body_data): new type.
 767         (stream_body, stream_handler): new procs.
 768
 769 2000-03-12  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 770
 771         * stacks.c, stacks.h, struct.c, tags.h, unif.c (scm_bits_t):
 772         Renamed from SCMWORD.
 773
 774         * tags.h (SCM_NCELLP): Removed (SCMWORD).
 775
 776         * arbiters.c (SCM_ARB_LOCKED): Use SCM_UNPACK_CAR.
 777
 778         * async.c, boolean.h, debug.c, dynl.c, dynwind.c, eval.c, eval.h,
 779           feature.h, filesys.h, fluids.h, fports.c, fports.h, gc.c, gc.h,
 780           hash.c, keywords.h, macros.c, numbers.c, numbers.h, objects.c,
 781           objects.h, options.c, pairs.h, ports.c, ports.h, print.c,
 782           procs.h, ramap.c, read.c, smob.c, smob.h, srcprop.h, stacks.c,
 783           stacks.h, strports.c, struct.c, struct.h, tag.c, tags.h,
 784           throw.c, unif.c, unif.h, variable.h, vectors.h, weaks.c,
 785           weaks.h (SCM_PACK, SCM_UNPACK, SCM_UNPACK_CAR): Renamed from
 786           SCM_ASSCM, SCM_ASWORD, SCM_CARW).
 787
 788         * numbers.h (SCM_SRS, SCM_INUM): Corrected SCM_ASSCM/ASWORD fixes.
 789
 790         * alist.c, eval.c, net_db.c, posix.c, print.c, snarf.h, struct.c,
 791         tags.h: Fixed copyright notices.
 792
 793         * struct.c, coop-threads.c: SCM_ASSCM/ASWORD fixes.
 794
 795 2000-03-12  Marius Vollmer  <mvo@zagadka.ping.de>
 796
 797         * init.c (scm_standard_stream_to_port): Check whether the file
 798         descriptor is valid and substitute "/dev/null" when not.
 799
 800 2000-03-12  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 801
 802         * coop-defs.h (struct timespec): Conditionally defined.
 803
 804         * coop.c (coop_condition_variable_timed_wait_mutex): Use ETIMEDOUT
 805         instead of ETIME.
 806
 807         * readline.c (match_paren): Bugfix: First arg to select is not
 808         number of descriptors but the number of the highest descriptor +
 809         1.
 810
 811         This is a preliminary attempt at a cleanup of the threads support
 812         code.  It moves things to better places, makes arguments more
 813         consistent with the POSIX API (which is used in GNOME's glib), and
 814         adds new functionality.
 815
 816         * readline.c (scm_init_readline): Added new arg to scm_init_mutex.
 817
 818         * coop-defs.h (scm_mutex_trylock): New macro: alias for
 819         coop_mutex_trylock.
 820         (scm_cond_init): Changed definition to
 821         coop_new_condition_variable_init.
 822
 823         * coop.c: #include <errno.h>
 824         (coop_timeout_qinsert): Moved here from iselect.c
 825         (coop_new_mutex_init, coop_new_condition_variable_init): New
 826         functions.  The strange names are temporary.  Use scm_mutex_init
 827         and scm_cond_init instead.
 828         (coop_mutex_trylock): New function.  Uses errno.h:EBUSY.  errno.h
 829         is ANSI C, but should we check for individual error codes in
 830         configure.in?
 831         (coop_condition_variable_timed_wait_mutex): New function.
 832         (coop_key_create, coop_setspecific, coop_getspecific,
 833         coop_key_delete): New functions.
 834
 835         * iselect.c (coop_timout_qinsert): Moved to coop.c
 836
 837 2000-03-11  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 838
 839         * pairs.h (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR,
 840         SCM_SETOR_CDR): Corrected SCM_ASSCM/WORD fixes.
 841
 842         * tags.h (SCM_VOIDP_TEST): Renamed from VOIDP_TEST.
 843         Layout cleanups.
 844
 845         * objects.h (SCM_CLASS_FLAGS, SCM_OBJ_CLASS_FLAGS,
 846         SCM_SET_CLASS_INSTANCE_SIZE), struct.h (SCM_STRUCT_VTABLE_DATA),
 847         proc.h (SCM_CLOSCAR): SCM_ASSCM/WORD fixes.
 848
 849         * eval.c (scm_lookupcar1): Inserted SCM_ASWORD in expressions
 850         dealing with ilocs.
 851
 852 2000-03-11  Dale P. Smith  <dpsm@en.com>, applied by Greg J. Badros, <gjb@cs.washington.edu>
 853
 854         * numbers.c (scm_copy_big_dec, scm_copy_smaller, scm_big_ior,
 855         scm_big_xor, scm_big_and, scm_big_test): Added new lowlevel bignum
 856         logical functions from SCM.
 857
 858         (logand, logior, logxor, logtest, logbit?): Extended scheme
 859         logical functions to use bignums from SCM.
 860
 861         (lognot): Removed call to `SCM_VALIDATE_INUM' that prevented
 862         lognot from using bignums.
 863
 864 Thu Mar  9 11:33:25 2000  Greg J. Badros  <gjb@cs.washington.edu>
 865
 866         * vectors.h (SCM_VELTS_AS_STACKITEMS): Added this macro to help in
 867         eliminating some warnings.
 868
 869         * unif.c, strports.c, print.c, options.c: Fix some warnings on
 870         mis-use of SCM/long
 871
 872         * gc.c, gc.h: Added scm_return_first_int(), and added comment re:
 873         what the scm_return_first* functions do.
 874
 875 2000-03-09  Han-Wen Nienhuys  <hanwen@cs.uu.nl>, applied by Greg J. Badros, <gjb@cs.washington.edu>
 876
 877        * libguile/*.[ch]: make a distinction between SCM as a generic
 878        name for a Scheme object (now a void*), and SCM as 32 bit word for
 879        storing tags and immediates (now a long int).  Introduced
 880        SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
 881        code in the process: arbiter.c (use macros), unif.c (scm_array_p),
 882
 883 Wed Mar  8 10:15:59 2000  Greg J. Badros  <gjb@cs.washington.edu>
 884
 885         * numbers.c:  Use SCM_VALIDATE_LONG_COPY, and longs, not ints, in
 886         various logXXX primitives.  Thanks Eric Moore!
 887
 888 Tue Mar  7 08:05:22 2000  Greg J. Badros  <gjb@cs.washington.edu>
 889
 890         * run-test, remaining-docs-needed:  Added these scripts.  The
 891         second one is only temporary until the docstring additions are
 892         complete.   run-test may best live on, but is here mostly for
 893         convenience and awareness for now.
 894
 895         * hash.c: Docs, minor cleanup patch from Dirk Herrman.
 896
 897 Thu Mar  2 16:06:58 2000  Greg J. Badros  <gjb@cs.washington.edu>
 898
 899         * error.h, error.c: Added `scm_wrong_type_arg_msg' to support
 900         displaying the expected type.  Use SCM_LISTn in a couple places
 901         instead of scm_cons-ing by hand.
 902
 903         * __scm.h: Added SCM_ASSERT_TYPE macro.
 904
 905         * validate.h, scm_validate.h: Added the former, as a renamed
 906         version of the latter with SCM_ASSERT_TYPE used in
 907         SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
 908
 909         * Makefile.am: Rename scm_validate.h to validate.h.
 910
 911         * *.c, *.h: Include validate.h, not scm_validate.h (old name's
 912         prefix was superfluous).
 913
 914 Thu Mar  2 15:33:12 2000  Greg J. Badros  <gjb@cs.washington.edu>
 915
 916         * hashtab.c: Improved documentation for lots of functions.  Added
 917         handwritten docs for `hash-fold'.
 918
 919 Thu Mar  2 15:13:25 2000  Greg J. Badros  <gjb@cs.washington.edu>
 920
 921         * list.c: Added hand-written docs for `del{q,v,ete}1!'.
 922
 923 Thu Mar  2 12:38:30 2000  Greg J. Badros  <gjb@cs.washington.edu>
 924
 925         * list.c: Moved append docs to append! Thanks Dirk Hermann.  Also,
 926         added append docs from R4RS.
 927
 928         * strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
 929         Thanks Dirk Hermann!
 930
 931         * chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
 932         deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR.  Thanks Dirk Hermann!
 933
 934         * *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
 935         Drop use of SCM_P for function prototypes... assume an ANSI C
 936         compiler.  Thanks Dirk Hermann!
 937
 938 Sat Feb 19 12:20:12 2000  Greg J. Badros  <gjb@cs.washington.edu>
 939
 940         * ports.c: Made `set-port-column!' and `set-port-line!' each
 941         return SCM_UNSPECIFIED instead of a (not-scheme-object) integer
 942         that caused a seg fault.  Also fixed `set-port-column!'s
 943         docstring.  Thanks Han-Wen Nienhuys for finding the bug!
 944
 945 Sun Feb 13 19:11:42 2000  Greg J. Badros  <gjb@cs.washington.edu>
 946
 947         * arbiters.c, eq.c, gc.c, guardians.c, list.c, ports.c, print.c,
 948         regex-posix.c, scmsigs.c, stime.c, strings.c, variable.c, stime.c,
 949         strings.c, variable.c:  Added lots of documentation, cleaned up
 950         some existing documentation.  Occasionally changed formal params
 951         to match docs.  Also folded an #ifdef into the inners of a
 952         primitive instead of having two copies of the primitive
 953         (`get-internal-real-time', from stime.c)
 954
 955 Sun Feb 13 18:12:19 2000  Greg J. Badros  <gjb@cs.washington.edu>
 956
 957         * ports.c: Added docs for primitives missing them.  Written by
 958         hand.
 959
 960 Sun Feb 13 09:40:36 2000  Greg J. Badros  <gjb@cs.washington.edu>
 961
 962         * guile-doc-snarf.in: Use ${AWK} -f guile-func-name-check, not
 963         just execing guile-func-name-check.  Thanks Michael Livshin!
 964
 965 Thu Feb 10 11:43:23 2000  Greg J. Badros  <gjb@cs.washington.edu>
 966
 967         * guile-snarf.awk.in: Tweak to work with Sun/HP awk, removed some
 968         dead code.  Patch from Michael Livshin.
 969
 970         * guile-doc-snarf.in: Tweak to work with Sun/HP sh.  Patch from
 971         Michael Livshin.
 972
 973 2000-02-09  Gary Houston  <ghouston@arglist.com>
 974
 975         * init.c (scm_init_standard_ports): when stdout is a tty, make the
 976         current-output-port unbuffered by default.  this is less confusing
 977         for interactive use.  it was line-buffered because of a
 978         performance problem with unbuffered ports, but I think it will be
 979         OK now.
 980
 981 2000-02-08  Gary Houston  <ghouston@arglist.com>
 982
 983         * __scm.h: don't define long_long or ulong_long if HAVE_LONG_LONGS
 984         is not defined.
 985
 986         * stime.c (scm_localtime, scm_mktime): if neither HAVE_TM_ZONE nor
 987         HAVE_TZNAME are defined, use an empty string instead of giving two
 988         spurious compile-time errors.
 989
 990 Tue Feb  8 13:57:46 2000  Greg J. Badros  <gjb@cs.washington.edu>
 991
 992         * ports.c: Doc patches from Richard Kim.  Pasted from MIT Scheme.
 993         Thanks Richard!

 995 Mon Feb  7 09:07:31 2000  Greg J. Badros  <gjb@cs.washington.edu>
 996
 997         * macros.c: Doc patches from Richard Kim.  Pasted from scm.texi.
 998
 999 Sun Feb  6 20:26:21 2000  Greg J. Badros  <gjb@cs.washington.edu>
1000
1001         * pairs.c: Doc patches from Richard Kim.  Pasted from MIT Scheme
1002         (which is GNU GPL'd).
1003
1004 2000-01-31  Gary Houston  <ghouston@arglist.com>
1005
1006         * strings.h: don't use SCM_P.  don't include <string.h>.
1007         * error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>.
1008
1009         * strings.c (scm_string_ref): make the 2nd argument compulsory.
1010         previously it defaulted to zero for no good reason that I can see.
1011         use a local variable for SCM_INUM (k).  replace
1012         SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
1013
1014         (scm_makfromstr): cosmetic changes.
1015
1016         (scm_string): Accept only chars in the list, not strings, for
1017         conformance to R5RS (particularly for list->string, which is
1018         supposed to be the inverse of string->list.)  remove
1019         SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
1020         scm_makstr handles the cell allocation.  when reporting wrong-type
1021         arg, don't report the position as 1.
1022
1023         * posix.c (scm_init_posix): intern PIPE_BUF if it's defined.
1024
1025 2000-01-29  Gary Houston  <ghouston@arglist.com>
1026
1027         * posix.c (scm_pipe): rewrote the docstring.
1028
1029         * filesys.c (scm_select, retrieve_select_type, get_element,
1030         fill_select_type, set_element): modified so that Scheme
1031         "select" tests port buffers for the ability to provide input
1032         or accept output.  Previously only the underlying file descriptors
1033         were checked.  Rewrote the docstring.
1034
1035 Thu Jan 27 10:14:25 2000  Greg J. Badros  <gjb@cs.washington.edu>
1036
1037         * vectors.c, symbols.c, strorder.c: Documentation cut and pasted

1041
1042         * strop.c (scm_i_index): Obfuscated commented-out SCM_DEFINE by
1043         adding "x" prefix to the line so that guile-func-name-check
1044         doesn't complain unnecessarily.
1045
1046 Wed Jan 26 17:33:52 2000  Greg J. Badros  <gjb@cs.washington.edu>
1047
1048         * throw.c: Factor out an #ifdef/#else/#endif choice more finely
1049         for maintainability.
1050
1051         * strop.c: Documentation added by Gregg A. Reynolds.   Pasted in
1052         from qdocs, RnRs.
1053
1054 Wed Jan 26 10:02:11 2000  Greg J. Badros  <gjb@cs.washington.edu>
1055
1056         * tag.c:  Added doc for `tag', but mark as deprecated since Mikael
1057         suggests removing tag.c altogether (and using a new `class-of'
1058         instead).
1059
1060         * strings.c:  Added documentation from Gregg A. Reynolds.  Edited
1061         a bit by me to use FOO instead of @var{foo} and to have the
1062         summary come before preconditions on input.  Also dropped trailing
1063         (rnrs) note.
1064
1065         * gsubr.c: Do not use SCM_DEFINE for `gsubr-apply'. Register the
1066         function with scm_make_subr_opt w/ last arg of 0 so it is not
1067         visible at the Scheme level. Mikael says that this is the right
1068         thing because the first arg to the proc is the guts of a compiled
1069         closure and shouldn't be exposed to the Scheme level.
1070
1071 Tue Jan 25 17:15:47 2000  Greg J. Badros  <gjb@cs.washington.edu>
1072
1073         * sort.c: typo in comment fixed.
1074
1075         * keywords.c: Added documentation.
1076
1077         * guardians.c: Added documentation (could be better).
1078
1079         * gc.c: Added docs for gc-set-debug-check-freelist.
1080
1081         * eq.c: Added docs for eq?, eqv? equal? abridged from R4RS.
1082
1083         * boolean.c: Added docs for `not', `boolean?' (by hand).
1084
1085 Tue Jan 25 13:28:56 2000  Greg J. Badros  <gjb@cs.washington.edu>
1086
1087         * random.c: Added documentation, from SLIB page:
1088         http://angela.ctrl-c.liu.se/~calle/scheme/slib_toc.html
1089
1090 Mon Jan 24 17:50:20 2000  Greg J. Badros  <gjb@cs.washington.edu>
1091
1092         * variable.c, version.c:  Added documentation, written by hand
1093         since I could not find anything already written that was
1094         relevant.
1095
1096 2000-01-23  Gary Houston  <ghouston@arglist.com>
1097
1098         * filesys.c (scm_chown): omit port/fdes support if HAVE_FCHOWN is
1099         not defined (thanks to Richard Y. Kim).
1100
1101 Thu Jan 20 13:00:38 2000  Greg J. Badros  <gjb@cs.washington.edu>
1102
1103         * Makefile.in: Removed, this is auto-generated.
1104
1105 Thu Jan 20 11:33:47 2000  Dirk Hermann <dirk@ida.ing.tu-bs.de> --applied 01/20/00 gjb
1106
1107         * list.c: Put some variable initialization code at the point of
1108         declaration; Added a comment for list*; Formatting changes.
1109
1110         * load.c: use SCM_NNULLP to make sure the end of a list is not
1111         reached yet.
1112
1113 2000-01-18  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1114
1115         * backtrace.c (scm_display_error_message): Bugfix: Don't use
1116         result of scm_list_p as C boolean.
1117         (scm_display_error_message, scm_set_print_params_x): Use new
1118         validation macros. (Thanks to Dirk Herrmann.)
1119
1120         * net_db.c (scm_resolv_error): Cast result from hstrerror.
1121
1122         * strports.c (st_end_input): Inserted parenthesis to get operator
1123         grouping correct.
1124
1125         * list.h (scm_init_list): Removed SCM_P around prototypes.
1126
1127         * fports.c, list.c, numbers.c, ports.c, stime.c, symbols.c,
1128         filesys.c, posix.c: Converted docstrings to ANSI C format and
1129         escaped " occurring inside string literals.
1130
1131 Tue Jan 18 13:21:08 2000  Mikael Djurfeldt  <mdj@r11n07-s.pdc.kth.se>
1132
1133         * posix.c (scm_mknod): Escape " occuring inside docstring.
1134
1135 2000-01-18  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1136
1137         * alist.c, chars.c, debug.c, dynl.c, dynwind.c, error.c, eval.c,
1138            evalext.c, filesys.c, gc.c, hash.c, hashtab.c, ioext.c,
1139            keywords.c, list.c, load.c, macros.c, net_db.c, numbers.c,

1143            symbols.c, throw.c, unif.c, vectors.c, version.c, vports.c,
1144            weaks.c: Converted docstrings to ANSI C format.
1145
1146         * filesys.c (scm_chmod), simpos.c (scm_system), version
1147         (scm_version), vports (scm_make_soft_port): Escape " occuring
1148         inside docstring.
1149
1150 Mon Jan 17 11:41:22 2000  Greg J. Badros  <gjb@cs.washington.edu>
1151
1152         * scm_validate.h: Added SCM_VALIDATE_ULONG_COPY,
1153         SCM_VALIDATE_LONG_COPY
1154
1155         * numbers.c: Use SCM_VALIDATE_ULONG_COPY, instead of
1156         SCM_VALIDATE_INUM_COPY to let bigger numbers be used.  Rename a
1157         couple of formal arguments (and fix their uses) to make arguments
1158         match the documentation.
1159
1160 2000-01-14    <mstachow@alum.mit.edu>
1161
1162         * Makefile.am: Augment path when running guile-doc-snarf so
1163         guile-func-name-check is found.
1164
1165 Fri Jan 14 09:34:55 2000  Greg J. Badros  <gjb@cs.washington.edu>
1166
1167         * scm_validate.h (SCM_NUM2LONG_DEF): Fix this macro to just use
1168         def, not SCM_MAKINUM(def);  thanks Janis Bzerins!
1169
1170 Wed Jan 12 00:06:53 2000  Greg J. Badros  <gjb@cs.washington.edu>
1171
1172         * net_db.c (s_scm_inet_makeaddr): Use SCM_NUM2ULONG since that's
1173         the way guile-1.3.4 worked, but #if 0 out the version using
1174         SCM_VALIDATE_INUM_COPY for stricter testing.
1175
1176 Tue Jan 11 18:24:18 2000  Greg J. Badros  <gjb@cs.washington.edu>
1177
1178         * guile-doc-snarf.in: Use new $fullfilename for running
1179         guile-func-name-check, and put "$fullfilename" and "$filename" in
1180         quotes at uses to make sure re-splitting on whitespace does not
1181         occur (so filenames w/ embedded whitespace would work okay, though
1182         I sure hope we never have to deal with that! :-) ).  Thanks to
1183         Mikael for pointing out the source_dir != build_dir was broken.
1184
1185 Tue Jan 11 17:42:40 2000  Greg J. Badros  <gjb@cs.washington.edu>
1186
1187         * scm_validate.h: Added SCM_NUM2LONG_DEF macro.  Make
1188         SCM_OUT_OF_RANGE use SCM_MAKINUM, not scm_long2num.  Added
1189         SCM_COERCE_ROSTRING macro.  Added SCM_VALIDATE_NONEMPTYLIST
1190         macro.  Fix SCM_VALIDATE_STRINGORSUBSTR macro to not use SLOPPY
1191         variants.
1192
1193         * ports.c (scm_port_closed_p): Validate that the arg is a PORT,
1194         then return whether it's an open port (was validating that it was
1195         an open port -- this was a bug I introduced back in December, but
1196         my careful reading of diffs caught it).
1197
1198         * numbers.c: Recombine the two conditional-compilation paths for
1199         all the log* primitives -- they were split based on #ifndef
1200         scm_long2num;  factored out a SCM_LOGOP_RETURN macro, and fixed
1201         some bugs and inconsistencies in the two sets of implementations.
1202         (scm_lognot) Fixed *atrocious* re-use of a SCM as an integer!
1203
1204         * ioext.c: Use SCM_ASSERT_RANGE in a couple places, and
1205         SCM_VALIDATE_INUM_COPY once where it should've been used.
1206
1207         * fluids.c (scm_internal_with_fluids): Use
1208         SCM_VALIDATE_LIST_COPYLEN.
1209
1210         * filesys.c: Use SCM_NUM2LONG instead of SCM_VALIDATE_INUM_COPY;
1211         this is questionable as it relaxes type safety, but other changes
1212         were useful and all SCM_NUM2LONG's should probably be
1213         revisited. Use SCM_OUT_OF_RANGE, SCM_WRONG_TYPE_ARG.
1214
1215         * evalext.c: line-break change on 1 line.
1216
1217         * eval.c (nconc2last): Takes a non-empty list as its first
1218         argument, not just a list.
1219
1220         * dynl.c: Use new SCM_COERCE_ROSTRING macro.
1221
1222 Tue Jan 11 15:44:23 2000  Greg J. Badros  <gjb@cs.washington.edu>
1223
1224         * dynl.c, feature.c, filesys.c, fports.c, list.c, load.c,
1225         net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
1226         where possible.
1227
1228         * symbols.c (scm_sysintern0): Fixed the function name in a
1229         scm_misc_error invocation.
1230
1231         * print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
1232         use scm_return_first to ward off latent GC bug that Mikael caught.
1233
1234         * async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
1235         used before but should've been.
1236
1237 2000-01-12  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
1238
1239         * snarf.h (SCM_PROC1): Replaced SCM (*) (...) with
1240         SCM_FUNC_CAST_ARBITRARY_ARGS.
1241
1242 Tue Jan 11 13:44:07 2000  Greg J. Badros  <gjb@cs.washington.edu>
1243
1244         * guile-func-name-check.in: Added this script to statically check
1245         #define FUNC_NAME, #undef FUNC_NAME in the source.
1246
1247         * sort.c, posix.c: Fix #undef FUNC_NAME lines to not have trailing
1248         redundant comment, semicolon; caught by new guile-func-name-check
1249         script.
1250
1251         * debug.c: Fix mistaken #define FUNC_NAME for scm_make_iloc.
1252         Caught by new guile-func-name-check-script.
1253
1254         * Makefile.am: Added guile-func-name-check to bin_SCRIPTS
1255
1256         * ramap.c: Fix #if 0'd out code to be syntactically acceptable to
1257         guile-func-name-check.
1258
1259         * guile-doc-snarf.in: Run guile-func-name-check on the file before
1260         doing the snarf.
1261
1262 Tue Jan 11 11:31:10 2000  Greg J. Badros  <gjb@cs.washington.edu>
1263
1264         * fports.c, ports.c, ports.h, strports.c, vports.c: Make write
1265         port function take const void*, not void*.
1266
1267 Tue Jan 11 11:18:07 2000  Greg J. Badros  <gjb@cs.washington.edu>
1268
1269         * scm_validate.h, chars.c, ports.c, print.c, read.c, strings.c,
1270         strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
1271         SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY.  Change made for
1272         consistency with the other macros dealing with immediate
1273         characters.  (Similar to INT -> INUM change a week or so ago).
1274
1275 Tue Jan 11 10:41:46 2000  Greg J. Badros  <gjb@cs.washington.edu>
1276
1277         * dynl.c, error.c, eval.c, feature.c, filesys.c, fports.c, list.c, load.c,
1278         net_db.c, read.c, socket.c: Update error messages to use ~A for
1279         %s, ~S for %S to work with new `simple-format' format and be
1280         standardized better.
1281
1282         * print.h, print.c (scm_simple_format): Added `simple-format'
1283         primitive.  It's the old scm_display_error, with ARGS now a rest
1284         parameter, and the destination first instead of last (and a couple
1285         new capabilities inspired by `format' -- #t as destination means
1286         current-output-port, #f means return the formatted text as a
1287         string.
1288
1289         * gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
1290
1291         * backtrace.c (scm_display_error_message): Rewrote to use
1292         scm_simple_format() procedure.
1293
1294         * __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
1295
1296 2000-01-09  Marius Vollmer  <mvo@zagadka.ping.de>
1297
1298         Finally applied the libltdl patch from Thomas Tanner, with slight
1299         modifications.
1300
1301         * DYNAMIC-LINKING: Removed because it is obsolete.
1302         * dynl.c: Use ANSI prototypes.
1303         (sysdep_dynl_link): Use lt_dlopenext instead of lt_dlopen.
1304         * scmconfig.h.in: Do not change, as it is automatically generated.
1305
1306     1999-07-25  Thomas Tanner  <tanner@ffii.org>
1307
1308             * dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c: deleted
1309             (obsolete)
1310             * Makefile.am: likewise, add INCLTDL (libltdl headers) to
1311             INCLUDES, set dlpreopened files in LDFLAGS, link libguile
1312             against libltdl
1313             * dynl.c: use libltdl if DYNAMIC_LINKING is enabled,
1314             * guile.c: register preloaded modules
1315             * scmconfig.h.in: remove obsolete symbols
1316
1317 2000-01-09  Gary Houston  <ghouston@arglist.com>
1318
1319         * These changes should make it unnecessary to call tzset from
1320         Scheme after modifying the TZ environment variable, even if the
1321         system date facilities cache the value.
1322         * stime.c (setzone, scm_localtime): added comments.
1323         (tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
1324         (setzone): don't call tzset.
1325         (restorezone): call tzset only if HAVE_TZSET is defined.
1326         (scm_tzset): don't define if HAVE_TZSET not defined.  Change the
1327         doc string to indicate that this procedure isn't likely to do
1328         anything useful.
1329         (scm_localtime, scm_strftime, scm_mktime): call tzset if
1330         LOCALTIME_CACHE is defined.
1331
1332 2000-01-09  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
1333
1334         * posix.c (scm_sync): Return SCM_UNSPECIFIED.
1335
1336 2000-01-09  Gary Houston  <ghouston@arglist.com>
1337
1338         * eval.c: define scm_unbound_variable_key ('unbound-variable).
1339         scm_lookupcar1: throw an error with key 'unbound-variable instead
1340         of 'misc-error when an unbound variable is encountered.
1341
1342         * filesys.c (scm_mkdir, scm_rmdir, scm_getcwd, scm_select,
1343         scm_symlink, scm_readlink, scm_lstat),
1344         posix.c (scm_setpgid, scm_setsid, scm_ctermid, scm_tcgetpgrp,
1345         scm_tcsetpgrp, scm_uname, scm_setlocale, scm_mknod, scm_nice,
1346         scm_sync),
1347         simpos.c (scm_system),
1348         stime.c (scm_times, scm_strptime):
1349         move the HAVE_XXX feature tests out of the procedure bodies.
1350         don't use SCM_SYSMISSING.
1351         scm_validate.h (SCM_SYSMISSING): removed.
1352         error.h, error.c (scm_sysmissing): comment that this is deprecated.
1353         see ChangeLog entry for 1999-12-28.

1355 Sat Jan  8 19:52:04 2000  Greg J. Badros  <gjb@cs.washington.edu>
1356
1357         * scm_validate.h (SCM_VALIDATE_BOOL_COPY): Fix typo.
1358
1359 Sat Jan  8 17:06:46 2000  Greg J. Badros  <gjb@cs.washington.edu>
1360
1361         * backtrace.c: Fix spelling typo in a comment.
1362
1363         * snarf.h: Use new SCM_DOCS macro to encapsulate the non SCM_INIT
1364         text.  Reformatted some of the expansions.
1365
1366 Fri Jan  7 15:50:46 2000  Greg J. Badros  <gjb@cs.washington.edu>
1367
1368         * scm_validate.h (SCM_OUT_OF_RANGE): Use scm_out_of_range_pos to
1369         report the position of the argument.
1370
1371         * error.h, error.c (scm_out_of_range_pos):  Added this function to
1372         take extra "pos" argument, the position number of the errant
1373         argument.
1374
1375         * debug.c: Use SCM_OUT_OF_RANGE instead of scm_out_of_range.
1376
1377         * snarf.h: Use SCM_HERE and SCM_INIT as names, not SCM_NOTSNARF
1378         and SCM_SNARFING.  Also put the %%% in the SCM_INIT since Mikael
1379         prefers that and I'm reasonably indifferent.

1381 Fri Jan  7 15:03:32 2000  Greg J. Badros  <gjb@cs.washington.edu>
1382
1383         * snarf.h: Factor out differences between C++ and non-C++ into
1384         SCM_FUNC_CAST_ARBITRARY_ARGS macro.  Modify all the snarf macro
1385         definitions to use SCM_NOTSNARF and SCM_SNARFING macros (like
1386         Mikael's macros, below, but changed names and SCM_SNARFING no
1387         longer expands to include %%% -- that must appear in the argument
1388         so that the token appears at the call-site as a reminder).

1390 2000-01-07  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
1391
1392         * snarf.h (SCM_INSITU, SCM_INIT): New snarf macros for use in user
1393         snarf macro definitions.
1394
1395 2000-01-06  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1396
1397         * chars.c (scm_integer_to_char): Use Greg's nice
1398         SCM_VALIDATE_INUM_RANGE macro for argument checking for closer
1399         adherence to R5RS.
1400
1401 Thu Jan  6 11:48:49 2000  Greg J. Badros  <gjb@cs.washington.edu>
1402
1403         * *.c, snarf.h: Replace GUILE_PROC1 with SCM_DEFINE1 throughout.
1404
1405 Thu Jan  6 11:22:53 2000  Greg J. Badros  <gjb@cs.washington.edu>
1406
1407         * Makefile.am (ETAGS_ARGS): Switch to SCM_DEFINE, SCM_DEFINE1
1408         instead of GUILE_PROC.
1409
1410 Thu Jan  6 11:21:49 2000  Greg J. Badros  <gjb@cs.washington.edu>
1411
1412         * alist.c: Do not report mismatch errors on some uses of `tmp' (do
1413         this by using SCM_ARG2 instead of `2' in the SCM_VALIDATE_CONS
1414         macro call.
1415
1416 Thu Jan  6 09:54:33 2000  Dirk Herrmann <dirk@ida.ing.tu-bs.de> --gjb applied
1417
1418         * scm_validate.h: Remove some redundant NIMP tests.
1419
1420         * alist.c: minimize scope of the tmp variables, and initialize
1421         them when declared. The strange SCM_NIMP tests are replaced by
1422         SCM_CONSP tests that more closely reflect the intended semantics.
1423         However, we don't get a performance penalty here, because the
1424         SCM_CONSP test was performed by the ALISTCELL test anyway.  * The
1425         extremely ugly use of ASRTGO macros was removed: The calls to
1426         ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a
1427         label parameter that only exists when SCM_RECKLESS is not defined.
1428         This works, because ASRTGO itself is defined in a way that it only
1429         makes use of the label parameter if SCM_RECKLESS is not defined
1430         (shudder!).  Does guile make at all use of the possibility to
1431         define SCM_RECKLESS?  * Codesize is likely to be reduced, since
1432         instead of two calls to SCM_ASSERT performed by the ALISTCELL test
1433         we now only get one test.
1434
1435         * list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate.  Also use
1436         SCM_NULLP instead of SCM_IMP.  Drop use of "register" keyword on
1437         some variables in `list?'.  Fix `reverse' and `reverse!'
1438         primitives to handle improper lists better.
1439
1440 Wed Jan  5 11:24:53 2000  Greg J. Badros  <gjb@cs.washington.edu>
1441
1442         * *.[ch]: Whitespace changes -- added space after SCM_VALIDATE_*
1443         macros and SCM_DEFINE macros to match GNU coding standards.
1444
1445 Wed Jan  5 11:04:24 2000  Greg J. Badros  <gjb@cs.washington.edu>
1446
1447         * *.[ch]: Replace GUILE_PROC w/ SCM_DEFINE.
1448
1449 Wed Jan  5 10:59:06 2000  Greg J. Badros  <gjb@cs.washington.edu>
1450
1451         * *.[ch]:  Replace SCM_VALIDATE_INT w/ SCM_VALIDATE_INUM for
1452         better consistency with the names of other SCM_VALIDATE_ macros
1453         and better conformance to guile naming policy.
1454
1455 Wed Jan  5 10:50:39 2000  Greg J. Badros  <gjb@cs.washington.edu>
1456
1457         * ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a
1458         SCM_VALIDATE instead of 1 to avoid a check on the argument (since
1459         it's not the actual name of the formal).
1460
1461         * guile-snarf.awk.in: Do argument/number mismatch checking and
1462         print warnings in an Emacs compile-mode parseable format.
1463
1464         * struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/
1465         SCM_OUTOFRANGE as 3rd argument.
1466
1467         * random.c: Fix argument/number mismatch (that I introduced :-( ).
1468
1469         * __scm.h: Do not #define SCM_ARG* when snarfing;
1470         lets us distinguish between 1 and SCM_ARG1 when snarfing as only
1471         the former (using the number) requires the argument to match the
1472         formal in the current argument snarfing check.
1473
1474         * snarf.h: Give new definition of SCM_ASSERT when in
1475         snarfing mode to output a lexically-identifiable sequence that the
1476         guile-snarf.awk script uses to verify argument/position matching.
1477
1478         * ramap.c: Remove extraneous #undef FUNC_NAME.
1479
1480 Wed Jan  5 08:36:38 2000  Greg J. Badros  <gjb@cs.washington.edu>
1481
1482         * guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the
1483         current version of the same functionality; it writes the .x output
1484         to stdout instead of directly into the file.
1485
1486 Wed Jan  5 08:15:04 2000  Greg J. Badros  <gjb@cs.washington.edu>
1487
1488         * unif.c, symbols.c, strings.c, stacks.c, random.c, print.c,
1489         posix.c:  Eliminated a bunch of SCM_NIMP(..)s that are now
1490         redundant with the safer macros.  Patch from Dirk Hermann applied
1491         by hand. Thanks Dirk!
1492
1493         * scm_validate.h: Added SCM_VALIDATE_VECTOR_OR_DVECTOR for some
1494         uses in random.c.
1495
1496         * ramap.c: whitespace change.
1497
1498 Tue Jan  4 14:21:35 2000  Greg J. Badros  <gjb@cs.washington.edu>
1499
1500         * options.c, objects.c, keywords.c, gc.c: Some redundant SCM_NIMP
1501         removals from Dirk Hermann.
1502
1503         * alist.c: Rename formals to match the parameter names in the
1504         documentation, updates to documentation.  Thanks Dirk Hermann!
1505
1506 2000-01-04  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1507
1508         * eval.c (SCM_CEVAL): Reverse order of
1509         scm_stack_checking_enabled_p and SCM_STACK_OVERFLOW_P
1510         (Thanks to Brad Knotwell.)
1511
1512 Mon Jan  3 08:30:02 2000  Greg Harvey  <Greg.Harvey@thezone.net> (applied --01/03/00 gjb)
1513
1514         * gc.c (scm_debug_newcell): Added SCM_SETCAR of the newly
1515         allocated cell.
1516
1517         * pairs.h: Added a comment about the need for the SCM_SETCAR in
1518         SCM_NEWCELL macro.
1519
1520 Mon Jan  3 08:25:19 2000  Greg J. Badros  <gjb@cs.washington.edu>
1521
1522         * dynl-vms.c, debug.c, coop-threads.c, backtrace.c, eval.c: More
1523         SCM_NIMP tests that were redundant are now eliminated.  Patches
1524         from Dirk Hermann applied by hand.
