   1 2000-03-29  Dirk Herrmann  <D.Herrmann@tu-bs.de>
   2
   3         * boolean.h (SCM_TRUE_P):  New macro.
   4
   5         * boolean.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOLP), pairs.h
   6         (SCM_NULLP, SCM_NNULLP):  Use SCM_EQ_P to compare SCM values.
   7
   8 2000-03-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>
   9
  10         * continuations.h (SCM_CONTREGS, SCM_SET_CONTREGS):  New macros to
  11         access continuation data.
  12
  13         (SCM_SETJMPBUF):  Deprecated.  Use SCM_SET_CONTREGS instead.
  14
  15         (SCM_JMPBUF, SCM_DYNENV, SCM_THROW_VALUE, SCM_BASE, SCM_SEQ,
  16         SCM_DFRAME):  Use SCM_CONTREGS instead of SCM_CHARS to access
  17         continuation data.
  18
  19         * continuations.c (scm_make_cont), init.c (start_stack),
  20         root.c (scm_internal_cwdr):  Use SCM_SET_CONTREGS instead of
  21         SCM_SETJMPBUF.
  22
  23 2000-03-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>
  24
  25         * symbols.h (SCM_LENGTH, SCM_SETLENGTH):  Access the length field
  26         of strings and symbols by using SCM_{SET_}?CELL_WORD_0.
  27
  28         (SCM_CHARS, SCM_UCHARS, SCM_SETCHARS):  Use SCM_{SET_}?CELL_WORD_1
  29         to access the char * field of strings and symbols.
  30
  31 2000-03-27  Dirk Herrmann  <D.Herrmann@tu-bs.de>
  32
  33         * gc.h (SCM_NEWCELL, SCM_NEWCELL2):  Use SCM_SET_CELL_TYPE to set
  34         the type entry of a new cell.  Added a comment about things to
  35         remember when updating the list of free cells.
  36
  37         (SCM_FREEP, SCM_MARKEDP):  Use SCM_CELL_TYPE to access the type
  38         entry of a cell.
  39
  40 2000-03-27  Dirk Herrmann  <D.Herrmann@tu-bs.de>
  41
  42         * pairs.h (SCM_CAR, SCM_CDR, SCM_SETCAR, SCM_SETCDR):  Use
  43         SCM_CELL_OBJECT and SCM_SET_CELL_OBJECT.  This change implies that
  44         with strict type checking enabled these macros will only work if
  45         given valid SCM parameters.
  46
  47         (SCM_GCCDR):  Moved to tags.h.
  48
  49         * tags.h (SCM_GCCDR):  Moved here from pairs.h.
  50
  51 2000-03-26  Dirk Herrmann  <D.Herrmann@tu-bs.de>
  52
  53         * tags.h (SCM2PTR, PTR2SCM):  Moved to gc.h.
  54
  55         * pairs.h (scm_cell, SCM_CELLPTR, SCM_CELL_WORD*, SCM_CELL_OBJECT*,
  56         SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*, SCM_CELL_TYPE,
  57         SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK, SCM_PTR_GT,
  58         SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC, SCM_NEWCELL,
  59         SCM_NEWCELL2):  Moved to gc.h.
  60
  61         (SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR, SCM_SETAND_CDR,
  62         SCM_SETOR_CAR, SCM_SETOR_CDR):  Moved to gc.h.  These names should
  63         be changed, though, since the macros are not only pair related.
  64
  65         (SCMPTR):  Deleted.
  66
  67         * gc.h (SCM2PTR, PTR2SCM, scm_cell, SCM_CELLPTR, SCM_CELL_WORD*,
  68         SCM_CELL_OBJECT*, SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*,
  69         SCM_CELL_TYPE, SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK,
  70         SCM_PTR_GT, SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC,
  71         SCM_NEWCELL, SCM_NEWCELL2, SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR,
  72         SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR):  Moved here from
  73         tags.h and pairs.h.
  74
  75 2000-03-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>
  76
  77         * tags.h (SCM_STRICT_TYPING):  New macro that, if defined,
  78         activates strict compile time type checking for variables of
  79         type SCM.
  80         (SCM, SCM_PACK, SCM_UNPACK):  Define according to whether
  81         SCM_STRICT_TYPING or SCM_VOIDP_TEST are defined.
  82         (SCM_EQ_P):  Defined as a macro equivalent for eq?.
  83
  84 2000-03-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>
  85
  86         * tags.h (SCM_POINTERS_MUNGED):  Removed.
  87
  88         * gc.c (scm_gc_sweep, init_heap_seg):  Removed use of
  89         SCM_POINTERS_MUNGED, thus fixing some illegal casts to SCM.
  90
  91 2000-03-24  Dirk Herrmann  <D.Herrmann@tu-bs.de>
  92
  93         * pairs.h (SCM_CELL_OBJECT, SCM_CELL_OBJECT_[0-3],
  94         SCM_SET_CELL_OBJECT, SCM_SET_CELL_OBJECT_[0-3], SCM_CELL_TYPE,
  95         SCM_SET_CELL_TYPE):  Added a set of low level macros for accessing
  96         cell entries.
  97         (SCM_CELL_WORD_[0-3]): Renamed from the SCM_CELL_WORD[0-3].
  98
  99         * procs.h, procs.c:  Instead of SCM_{SET_}?CELL_WORD[12], use the
 100         newly introduced SCM_{SET_}?CELL_OBJECT_[12] macros.
 101
 102 2000-03-23  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 103
 104         * tags.h: Disabled definition of SCM_VOIDP_TEST.
 105
 106         Defining SCM as void * introduces problems which haven't been
 107         handled yet.  Developers who work with these issues can enable it
 108         in their working copies.
 109
 110         Disabling this definition exposes a set of newly introduced and
 111         older misuses of types which causes warning messages during
 112         compilation.  We'll fix this successively.
 113
 114         * gc.c (scm_mark_locations): Changed * (SCM **) X --> * (SCM *) X
 115         in order to obtain a value of type SCM.
 116         (scm_cellp): Updated with new changes to scm_mark_locations.
 117
 118         * continuations.h (SCM_SETJMPBUF): Cast second arg into SCM.
 119
 120         * continuations.c (scm_make_cont): Removed cast of size_t into
 121         long.
 122
 123         * symbols.h (SCM_SETCHARS): Cast second arg into SCM.
 124
 125 2000-03-22  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 126
 127         * numbers.h (SCM_SETNUMDIGS):  Use SCM_BIGSIZEFIELD macro for
 128         shifting, not constant.  Thanks to Dale P. Smith.
 129
 130         * numbers.c (scm_sum, scm_difference):  Don't test a SCM value
 131         for being less than zero.  Decode it to a C value first.  Again,
 132         thank you Dale.
 133
 134 2000-03-22  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 135
 136         * numbers.h, ramap.c, struct.h, vectors.h:  Don't use SCM2PTR for
 137         non scheme values.  If raw data is stored in SCM variables, it has
 138         to be accessed using SCM_UNPACK until a better solution is found.
 139
 140 2000-03-22  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 141
 142         * tags.h (SCM_ECONSP, SCM_NECONSP): More corrections of
 143         pointer-arithmetic induced by the SCM_PACK/UNPACK change.
 144
 145         * print.c (scm_iprin1): SCM_PACK/UNPACK corrections.
 146
 147         * gc.c (scm_gc_sweep): SCM_PACK/UNPACK corrections.
 148
 149         * eval.c (SCM_CEVAL, scm_unmemocar): SCM_PACK/UNPACK corrections.
 150
 151         * dynwind.c (scm_swap_bindings): SCM_PACK/UNPACK corrections.
 152
 153         * async.c, __scm.h: Removed lots of the old async click logic.  It
 154         is possible to reinsert it by defining GUILE_OLD_ASYNC_CLICK in
 155         __scm.h.  Let's try this out and dump the old code after the
 156         threads reorganization.
 157         (set-tick-rate, set-switch-rate): Conditionally removed.
 158
 159 2000-03-21  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 160
 161         * gc.c (scm_gc_mark): Bugfix 1: The recent SCM_PACK/UNPACK change
 162         made SCM values into pointers.  This turned an arithmetic
 163         computation of the address of the vcell into a pointer-arithmetic
 164         one, thereby screwing up marking of structs.
 165         Bugfix 2: Removed incompletely introduced loop variable `j' used
 166         when protecting the tail array of a struct.
 167
 168 2000-03-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 169
 170         * struct.h (SCM_STRUCT_DATA):  Don't cast SCM values to pointers.
 171
 172 2000-03-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 173
 174         * symbols.h, symbols.c (scm_strhash):  Declare the string
 175         parameter as constant, since it is not modified.
 176
 177         * symbols.c (scm_intern_obarray_soft,
 178         scm_sysintern0_no_module_lookup):  Can now pass constant strings
 179         to scm_strhash without need for casting.
 180
 181 2000-03-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 182
 183         * vectors.h (SCM_VELTS, SCM_VELTS_AS_STACKITEMS):  Don't cast SCM
 184         values to pointers.  Use SCM2PTR instead.
 185
 186 2000-03-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 187
 188         * async.c (scm_set_tick_rate, scm_set_switch_rate):  Don't unpack
 189         results of SCM_INUM.
 190
 191 2000-03-21  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 192
 193         * init.c (scm_boot_guile_1): Renamed GUILE_GC_TRIGGER_1 -->
 194         GUILE_MIN_YIELD_1, GUILE_GC_TRIGGER_2 --> GUILE_MIN_YIELD_2.
 195         GUILE_MIN_YIELD_X now take *positive* fractions of heap size.
 196
 197         * gc.c, gc.h (SCM_MIN_YIELD_1, SCM_MIN_YIELD_2,
 198         min_yield_fraction, min_yield, adjust_min_yield): Renamed from
 199         SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2, gc_trigger_fraction,
 200         gc_trigger, adjust_gc_trigger.
 201
 202         * gc.c (alloc_some_heap): Further improvement of minimal heap size
 203         prediction.
 204         (SCM_MAX): New macro.
 205         (scm_freelist_t): New field: collected_1. Previous amount of
 206         collected cells.
 207         (gc_sweep_freelist_finish): Trigger based on two last values of
 208         freelist->collected to avoid unnecessary allocation due to
 209         temporary peaks.
 210         (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2):
 211         Adjusted to 45000 cells, 40% and 40%.  Gives quick startup
 212         without extra heap allocation.
 213
 214 2000-03-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 215
 216         * numbers.h (SCM_MAKINUM):  The parameter to SCM_MAKINUM should
 217         already be a C value.  No need to unpack it.
 218
 219         * numbers.c (scm_long_long2num):  Cast the parameter to scm_bits_t
 220         if we know it fits into an inum.
 221
 222         * ramap.c (ramap_rp):  An scm_tc7_[ui]vect object does point to a
 223         field of long values.  In contrast, SCM_VELTS accesses a field of
 224         SCM values.
 225
 226 2000-03-20  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 227
 228         * gc.c (scm_gc_stats): Inserted explanation of local_scm_mtrigger
 229         etc.
 230         (scm_gc_yield_1): New variable: Holds previous yield.  Used to
 231         make better judgements.
 232         (gc_sweep_freelist_finish): Inserted explanation of use of
 233         gc_trigger.
 234
 235         * print.h, stacks.h, options.c, options.h: Changed C++
 236         commentaries to C.
 237
 238 2000-03-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 239
 240         * tags.h (SCM2PTR, PTR2SCM):  Use SCM_PACK / SCM_UNPACK correctly.
 241
 242         * numbers.h (SCM_INUMP, SCM_MAKINUM, SCM_INUM0, SCM_COMPLEX_REAL,
 243         SCM_COMPLEX_IMAG, SCM_NUMP, SCM_BDIGITS):  Use SCM_PACK /
 244         SCM_UNPACK / SCM2PTR correctly.
 245
 246 2000-03-20  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 247
 248         * gc.c (adjust_gc_trigger): Improved documentation.
 249         (alloc_some_heap): Since gc_trigger is used against
 250         freelist->collected, this is the value which should be used to
 251         predict minimum growth.
 252
 253 2000-03-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 254
 255         * eval.h:  Fix mixup of packed/unpacked SCM values.  (Thanks
 256         Thien-Thi Nguyen for the patch.)
 257
 258 2000-03-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 259
 260         * numbers.c (scm_ash):  Fixed typing problems with the second
 261         parameter and added some documentation.  (Thanks Thien-Thi Nguyen
 262         for indicating the problem.)
 263
 264 2000-03-19  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 265
 266         * gc.c, gc.h (scm_gc_yield): New variable.
 267         (adjust_gc_trigger): Use scm_gc_yield.
 268         (alloc_some_heap): Use scm_gc_yield instead of
 269         scm_gc_cells_collected.
 270
 271         * coop-threads.c: Addd #include "root.h", #include "strings.h".
 272
 273         * debug.c: Added #include "root.h".  (Thanks to Thien-Thi Nguyen.)
 274
 275         * gc.c (scm_gc_for_newcell, adjust_gc_trigger): Improved GC
 276         trigger adjustmeant: Take yield (freed cells) for all freelists
 277         into account.
 278         (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Tuned
 279         to 50000 cell heap with 45% trigger.
 280         (scm_gc_cells_collected): Reintroduced.
 281         (SCM_HEAP_SIZE): New macro.
 282         (scm_gc_sweep): Reintroduced correct computation of
 283         scm_cells_allocated.
 284         (scm_freelist_t): Corrected commentary for field `cluster_size':
 285         Clustersize counts objects, not cells;  New member
 286         `clusters_allocated'.
 287
 288 2000-03-19  Michael Livshin  <mlivshin@bigfoot.com>
 289
 290         * *.[hc]: add Emacs magic at the end of file, to ensure GNU
 291         indentation style.
 292
 293 2000-03-19  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 294
 295         * threads.h: Added #include "libguile/throw.h".  (Thanks to
 296         Thien-Thi Nguyen.)
 297
 298 2000-03-18  Michael Livshin  <mlivshin@bigfoot.com>
 299
 300         * tags.h: (SCM_DOUBLE_CELLP, SCM_NDOUBLE_CELLP): new macros.
 301
 302         * gc.h: (typedef struct scm_freelist_t) remove from here.
 303
 304         * gc.c: (CELL_UP, CELL_DN) make these macros take additional
 305         parameter (the span).
 306         (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK) new macros.
 307         (typedef struct scm_freelist_t) move here from gc.h, it had no
 308         business being externally visible.
 309         (typedef struct scm_heap_seg_data_t) renamed from
 310         scm_heap_seg_data, to be style-compliant.
 311         (scm_mark_locations) if the possible pointer points to a
 312         multy-cell, check that it's properly aligned.
 313         (init_heap_seg) alighn multy-cells properly, work with the
 314         assumption that the segment size divides cleanly by cluster size
 315         (so that there's no spill).
 316         (round_to_cluster_size) new function.
 317         (alloc_some_heap, make_initial_segment) use round_to_cluster_size
 318         to satisfy the new init_heap_seg invariant.
 319
 320 2000-03-18  Dirk Herrmann  <D.Herrmann@tu-bs.de>

 377 2000-03-17  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 378
 379         * gc.c, gc.h: Cleanup of the change of 2000-03-15.
 380         Cluster sizes are now independent of GC trigger values.
 381         GUILE_GC_TRIGGER_n can now specify a relative trigger value:
 382         A negative integer gives fraction of total heap size in percent.
 383         (SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Default values set to -40.
 384
 385         * init.c (scm_boot_guile_1): Introduced new variable
 386         GUILE_MAX_SEGMENT_SIZE; New environment variable names:
 387         GUILE_INIT_SEGMENT_SIZE_1, GUILE_GC_TRIGGER_1,
 388         GUILE_INIT_SEGMENT_SIZE_2, GUILE_GC_TRIGGER_2
 389
 390 2000-03-16  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 391
 392         * __scm.h (GC_FREE_SEGMENTS): Disable this until we have made
 393         freeing of segment work with the new GC scheme.  (Thanks to
 394         Michael Livshin.)  Oops, also happened to make GUILE_NEW_GC_SCHEME
 395         the default, but I'll let this change stay in CVS Guile since this
 396         code is not expected to contain serious bugs.
 397
 398 2000-03-16  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 399
 400         * gc.c, gc.h (scm_map_free_list): Define also if GUILE_DEBUG is
 401         defined.
 402         (scm_free_list_length): New procedure (GUILE_DEBUG).
 403         Fixed a small but serious bug introduced by the previous change.
 404
 405         * gc.c (scm_gc_sweep): Moved variable n_objects to inner sweep
 406         loop and declare as register.
 407
 408         * gc.c (scm_gc_sweep): Sigh... forgot to clear private freelists
 409         after GC.
 410
 411 Wed Mar 15 08:27:04 2000  Greg J. Badros  <gjb@cs.washington.edu>
 412
 413         * fluids.c: Docstring patch from Keisuke Nishida.  Some
 414         reindentation, too, and a couple formals renamed.  Should
 415         fluid-set! return UNSPECIFIED instead of a value?
 416
 417 Wed Mar 15 08:24:58 2000  Greg J. Badros  <gjb@cs.washington.edu>
 418
 419         * Makefile.am: Separate out DOT_X_FILES and DOT_DOC_FILES, and
 420         generate the latter from the concrete listing of the former.  Then
 421         make guile-procedures.txt depend on DOT_DOC_FILES instead of
 422         *.doc, so that rebuilding it works.
 423
 424 Wed Mar 15 08:12:14 2000  Greg J. Badros  <gjb@cs.washington.edu>
 425
 426         * libguile.h: Include libguile/validate.h.  Thanks Keisuke Nishida!
 427
 428         * guile-snarf.awk.in: Replace docstring line-ending \n" and \n\n"
 429         with nothing and \n, respectively. Thanks Keisuke Nishida for
 430         noticing this problem.
 431
 432 2000-03-15  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 433
 434         * __scm.h (GUILE_NEW_GC_SCHEME): Define this if you want to test a
 435         new way of allocating heap.  It makes Guile fast, but still
 436         contains bugs.
 437
 438         * gc.c, gc.h, pairs.h, init.c: Implementation of a new way of
 439         allocating heap.  The basic idea is to trigger GC every Nth
 440         allocated cell and grow heap when free list runs out.  The scheme
 441         has been extended so that GC isn't triggered until all remaining
 442         cells are used.  The implementation is also prepared for
 443         development in the direction of POSIX threads.
 444
 445         * gc.c (SCM_EXPHEAP): In order to grow by a factor of 1.5,
 446         SCM_EXPHEAP should return half of the heap size.
 447
 448 2000-03-14  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 449
 450         The following change to init.c is only enabled if Guile was
 451         configured with --enable-guile-debug.
 452
 453         * init.c (scm_i_getenv_int): New function.
 454         (scm_boot_guile_1): Use the environment variables
 455         GUILE_INIT_HEAP_SIZE, GUILE_INIT_HEAP_SIZE2 to select heap size if
 456         they exist.  (This may be replaced by a Scheme level mechanism in
 457         the future.)
 458
 459         * objprop.c (s_scm_set_object_property_x): Use scm_assq instead of
 460         scm_assoc.  (Thanks to Keisuke Nishida.)
 461
 462 2000-03-14  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 463
 464         * eval.c, lang.c, lang.h (scm_lisp_nil, scm_lisp_t): Renamed from
 465         scm_nil, scm_t.  (Thanks to Keisuke Nishida.)
 466
 467 2000-03-14  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 468
 469         * init.c (scm_boot_guile_1): Use same initial segment size for
 470         1-word and 2-word segments.  Having the smaller size causes Guile
 471         to GC too often.  Obviously something needs to be done to allow
 472         for a smaller 2-word segment without this to happen.  (The amount
 473         of heap for each type should be automatically adapted to the
 474         application somehow.)
 475
 476         [Almost all of these changes should be documented in the NEWS
 477         file.]
 478
 479         * gc.h (scm_freelist_t): New type.
 480
 481         * pairs.h (SCM_NEWCELL, SCM_NEWCELL2): Use new style freelists.
 482
 483         * gc.c (SCM_INIT_HEAP_SIZE): Changed from 32768 --> 40000 so that
 484         all of Guile basics fits into one segment and there suitable room
 485         for work.
 486         (SCM_EXPHEAP): Now takes an argument.  Grow by a factor of 1.5
 487         instead of 2.
 488         (scm_freelist, scm_freelist2): Now of type scm_freelist_t.
 489         Freelists now contains information about object span, cells
 490         collected and amount of cells in heap segments belonging to the
 491         list.
 492         (scm_heap_size, scm_gc_cells_collected): Removed.
 493
 494         * init.c (scm_boot_guile_1): Make 2-word segment 8K (512 cells).
 495
 496         * Makefile.am (libguile_la_LDFLAGS): Bumped library version
 497         number.
 498
 499         * __scm.h eq.c, eval.c, gc.c, gc.h, gh_data, hash.c, numbers.c,
 500         numbers.h, objects.c, ramap.c, random.c, unif.c, unif.h: Extensive
 501         rewrite of handling of real and complex numbers.
 502         (SCM_FLOATS, SCM_SINGLES): These #ifdef conditionals have been
 503         removed along with the support for floats.  (Float vectors are
 504         still supported.)
 505
 506         * tags.h (scm_tcs_bignums): Removed.
 507         (scm_tc16_bigpos, scm_tc16_bigneg): Replaced by scm_tc16_big.
 508         Use SCM_BIGSIGN(x) to test for sign!
 509         (scm_tc16_big): The new bignum type.
 510         (SCM_REAL_PART, SCM_IMAG_PART): Removed.
 511
 512         * numbers.h (SCM_BIGSIGN): Sign moved to bit 16.
 513         (scm_makdbl): Deprecated.
 514         (SCM_NEWREAL, SCM_NEWCOMPLEX): New macros.
 515         (SCM_SINGP): Deprecated.
 516         (SCM_FLO): Removed.
 517         (SCM_INEXP, SCM_CPLXP): Deprecated.
 518         (SCM_INEXACTP, SCM_COMPLEXP): New macros.
 519         (SCM_COMPLEX_REAL, SCM_COMPLEX_IMAG): Renamed from
 520         SCM_REAL, SCM_IMAG (and now only valid for complex numbers).
 521         (SCM_REAL, SCM_IMAG): New, *deprecated*, selectors which work both
 522         for doubles and complex numbers.
 523         (SCM_REAL_VALUE): New selector for doubles.
 524         (scm_double_t, scm_complex_t): New types.
 525         (scm_dbl): Removed.
 526
 527         * numbers.c (scm_floprint, scm_floequal): Removed.
 528         (scm_print_real, scm_print_complex, scm_real_equalp,
 529         scm_complex_equalp): New functions.
 530
 531         * unif.c (scm_makflo): Removed.
 532
 533         * smob.h (SCM_SMOB_PREDICATE): New macro.
 534         (SCM_NEWSMOB2, SCM_RETURN_NEWSMOB2, SCM_NEWSMOB3,
 535         SCM_RETURN_NEWSMOB3): New macros.
 536
 537 1999-11-21  Michael Livshin  <mlivshin@bigfoot.com>
 538
 539         The following changes implement primitive support for double cells
 540         (i.e. four-word cells) and change the representation of some
 541         things to multi-cells instead of cons+malloc.  (Applied and
 542         modified by mdj.)
 543
 544         * pairs.h (SCM_NEWCELL2): double-cell variants of SCM_NEWCELL.
 545         (SCM_CELL_WORD, SCM_CELL_WORDLOC, SCM_SET_CELL_WORD): primitive
 546         multi-cell access macros (used by the ones below).
 547         (SCM_CELL_WORD[0-3], SCM_SET_CELL_WORD[0-3]): multi-cell access
 548         macros.
 549
 550         * gc.c (scm_freelist2): multi-cell freelists.
 551         (inner_map_free_list): map_free_list, parameterized on ncells.
 552         "nn cells in segment mm" was misleading for ncells > 1; changed to
 553         "objects".  still print cells too, though.
 554         (scm_map_free_list): rewritten using inner_map_free_list.
 555         (scm_check_freelist): get freelist as parameter, since now we have
 556         more than one.
 557         (scm_debug_newcell2): multi-cell variants of
 558         scm_debug_newcell.
 559         (scm_gc_for_newcell): take ncells and freelist pointer as
 560         parameters.
 561         (scm_gc_mark): add case for tc7_pws (procedures with setters are
 562         now double cells).
 563         (scm_gc_sweep): don't free the float data, since it's not malloced
 564         anymore.
 565         (init_heap_seg): didn't understand what n_new_objects stood for,
 566         so changed to n_new_cells.
 567         (make_initial_segment): new function, makes an initial segment
 568         according to given ncells.
 569         (scm_init_storage): call make_initial_segment, for ncells={1,2,3}.
 570
 571         * numbers.c (scm_makdbl): no malloc'ing needed, so the
 572         {DEFER,ALLOW}_INTS thing removed.
 573
 574         * numbers.h (struct scm_dbl): changed to represent a double cell,
 575         with the number in the second half.
 576
 577         * dynwind.c: changed the wind-guards representation to double
 578         cell.
 579
 580         * procs.c, procs.h: changed the procedure-with-setter representation
 581         to double cell.
 582
 583         * async.c, async.h: made async representation a double cell.
 584
 585         * dynl.c: made dynamic_obj representation a double cell.
 586
 587 2000-03-13  Gary Houston  <ghouston@arglist.com>
 588
 589         * ports.c (flush_void_port): renamed to flush_port_default.
 590         (end_input_void_port): renamed to end_input_default.
 591
 592         * init.c (scm_standard_stream_to_port): create a void port instead
 593         of opening /dev/null if the standard file descriptors are bad.
 594         advantages: no portability problems, doesn't waste a file descriptor,
 595         simplifies the code (thanks to Marius for the idea).
 596
 597         * vports.c (s_scm_make_soft_port): call scm_port_non_buffer.
 598
 599         * void ports: make reading from a void port give EOF instead of
 600         segv:
 601         * ports.c (s_scm_sys_make_void_port): modified docstring.
 602         (fill_input_void_port): new proc.
 603         (scm_init_ports): set up fill_input_void_port.
 604         * ports.c (scm_port_non_buffer): new proc.
 605         (scm_void_port): call scm_port_non_buffer.
 606
 607         * fports.c (scm_setvbuf): docstring: remove the fcntl documentation
 608         which was incorrectly appended.
 609
 610 2000-03-13  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 611
 612         * guile-doc-snarf.in: Don't use absolute path for `sed'.  (Note
 613         that we can't use autoconf for this.  Autoconf itself relies on
 614         the existence of `sed' somewhere on your path.)  (Thanks to Dirk
 615         Herrman.)
 616
 617 2000-03-13  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 618
 619         * Makefile.am (libguile_la_SOURCES): Moved iselect.c here from
 620         EXTRA_libguile_la_SOURCES.
 621
 622         * iselect.h: Always declare scm_internal_select.
 623
 624         * iselect.c (scm_internal_select): Added SCM_ASYNC_TICK at the
 625         end.  Also let scm_internal_select be a real function also when
 626         not using threads.
 627
 628         * __scm.h (SCM_TICK): Oops! Forgot to put SCM_ASYNC_TICK here...
 629
 630 2000-03-13  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 631
 632         * __scm.h (SCM_ALLOW_INTS, SCM_REALLOW_INTS): Removed call to
 633         SCM_ASYNC_TICK.  (This is a preparation for POSIX threads support,
 634         and kind of an experiment: Will this cause problems?)
 635
 636 Sun Mar 12 13:26:30 2000  Greg J. Badros  <gjb@cs.washington.edu>
 637
 638         * Makefile.am: Added *.doc to DISTCLEANFILES.
 639
 640 2000-03-12  Gary Houston  <ghouston@arglist.com>
 641
 642         * fports.c (scm_fdes_to_port): call fcntl F_GETFL to test that
 643         the fdes is valid before doing anything else.  check that
 644         the file descriptor supports the modes required.
 645         (scm_fport_buffer_add): don't throw an error if fstat doesn't
 646         work: just use the default buffer size.
 647
 648         * throw.c: change an outdated comment about scm_internal_catch
 649         BODY: it doesn't take a jumpbuf arg.
 650
 651         * init.c (scm_standard_stream_to_port): install a handler in case
 652         scm_fdes_to_port throws an error.  don't check here whether the
 653         file descriptor is valid, since scm_fdes_to_port will do that.
 654         set the revealed count depending on whether the port got the
 655         standard file descriptor.
 656         (stream_body_data): new type.
 657         (stream_body, stream_handler): new procs.
 658
 659 2000-03-12  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 660
 661         * stacks.c, stacks.h, struct.c, tags.h, unif.c (scm_bits_t):
 662         Renamed from SCMWORD.
 663
 664         * tags.h (SCM_NCELLP): Removed (SCMWORD).
 665
 666         * arbiters.c (SCM_ARB_LOCKED): Use SCM_UNPACK_CAR.
 667
 668         * async.c, boolean.h, debug.c, dynl.c, dynwind.c, eval.c, eval.h,
 669           feature.h, filesys.h, fluids.h, fports.c, fports.h, gc.c, gc.h,

 675           weaks.h (SCM_PACK, SCM_UNPACK, SCM_UNPACK_CAR): Renamed from
 676           SCM_ASSCM, SCM_ASWORD, SCM_CARW).
 677
 678         * numbers.h (SCM_SRS, SCM_INUM): Corrected SCM_ASSCM/ASWORD fixes.
 679
 680         * alist.c, eval.c, net_db.c, posix.c, print.c, snarf.h, struct.c,
 681         tags.h: Fixed copyright notices.
 682
 683         * struct.c, coop-threads.c: SCM_ASSCM/ASWORD fixes.
 684
 685 2000-03-12  Marius Vollmer  <mvo@zagadka.ping.de>
 686
 687         * init.c (scm_standard_stream_to_port): Check whether the file
 688         descriptor is valid and substitute "/dev/null" when not.
 689
 690 2000-03-12  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 691
 692         * coop-defs.h (struct timespec): Conditionally defined.
 693
 694         * coop.c (coop_condition_variable_timed_wait_mutex): Use ETIMEDOUT
 695         instead of ETIME.
 696
 697         * readline.c (match_paren): Bugfix: First arg to select is not
 698         number of descriptors but the number of the highest descriptor +
 699         1.
 700
 701         This is a preliminary attempt at a cleanup of the threads support
 702         code.  It moves things to better places, makes arguments more
 703         consistent with the POSIX API (which is used in GNOME's glib), and
 704         adds new functionality.
 705
 706         * readline.c (scm_init_readline): Added new arg to scm_init_mutex.
 707
 708         * coop-defs.h (scm_mutex_trylock): New macro: alias for
 709         coop_mutex_trylock.
 710         (scm_cond_init): Changed definition to
 711         coop_new_condition_variable_init.
 712
 713         * coop.c: #include <errno.h>
 714         (coop_timeout_qinsert): Moved here from iselect.c
 715         (coop_new_mutex_init, coop_new_condition_variable_init): New
 716         functions.  The strange names are temporary.  Use scm_mutex_init
 717         and scm_cond_init instead.
 718         (coop_mutex_trylock): New function.  Uses errno.h:EBUSY.  errno.h
 719         is ANSI C, but should we check for individual error codes in
 720         configure.in?
 721         (coop_condition_variable_timed_wait_mutex): New function.
 722         (coop_key_create, coop_setspecific, coop_getspecific,
 723         coop_key_delete): New functions.
 724
 725         * iselect.c (coop_timout_qinsert): Moved to coop.c
 726
 727 2000-03-11  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 728
 729         * pairs.h (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR,
 730         SCM_SETOR_CDR): Corrected SCM_ASSCM/WORD fixes.
 731
 732         * tags.h (SCM_VOIDP_TEST): Renamed from VOIDP_TEST.
 733         Layout cleanups.
 734
 735         * objects.h (SCM_CLASS_FLAGS, SCM_OBJ_CLASS_FLAGS,
 736         SCM_SET_CLASS_INSTANCE_SIZE), struct.h (SCM_STRUCT_VTABLE_DATA),
 737         proc.h (SCM_CLOSCAR): SCM_ASSCM/WORD fixes.
 738
 739         * eval.c (scm_lookupcar1): Inserted SCM_ASWORD in expressions
 740         dealing with ilocs.

 743
 744         * numbers.c (scm_copy_big_dec, scm_copy_smaller, scm_big_ior,
 745         scm_big_xor, scm_big_and, scm_big_test): Added new lowlevel bignum
 746         logical functions from SCM.
 747
 748         (logand, logior, logxor, logtest, logbit?): Extended scheme
 749         logical functions to use bignums from SCM.
 750
 751         (lognot): Removed call to `SCM_VALIDATE_INUM' that prevented
 752         lognot from using bignums.
 753
 754 Thu Mar  9 11:33:25 2000  Greg J. Badros  <gjb@cs.washington.edu>
 755
 756         * vectors.h (SCM_VELTS_AS_STACKITEMS): Added this macro to help in
 757         eliminating some warnings.
 758
 759         * unif.c, strports.c, print.c, options.c: Fix some warnings on
 760         mis-use of SCM/long
 761
 762         * gc.c, gc.h: Added scm_return_first_int(), and added comment re:
 763         what the scm_return_first* functions do.
 764
 765 2000-03-09  Han-Wen Nienhuys  <hanwen@cs.uu.nl>, applied by Greg J. Badros, <gjb@cs.washington.edu>
 766
 767        * libguile/*.[ch]: make a distinction between SCM as a generic
 768        name for a Scheme object (now a void*), and SCM as 32 bit word for
 769        storing tags and immediates (now a long int).  Introduced
 770        SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
 771        code in the process: arbiter.c (use macros), unif.c (scm_array_p),
 772
 773 Wed Mar  8 10:15:59 2000  Greg J. Badros  <gjb@cs.washington.edu>
 774
 775         * numbers.c:  Use SCM_VALIDATE_LONG_COPY, and longs, not ints, in
 776         various logXXX primitives.  Thanks Eric Moore!
 777
 778 Tue Mar  7 08:05:22 2000  Greg J. Badros  <gjb@cs.washington.edu>
 779
 780         * run-test, remaining-docs-needed:  Added these scripts.  The
 781         second one is only temporary until the docstring additions are
 782         complete.   run-test may best live on, but is here mostly for
 783         convenience and awareness for now.
 784
 785         * hash.c: Docs, minor cleanup patch from Dirk Herrman.
 786
 787 Thu Mar  2 16:06:58 2000  Greg J. Badros  <gjb@cs.washington.edu>
 788
 789         * error.h, error.c: Added `scm_wrong_type_arg_msg' to support
 790         displaying the expected type.  Use SCM_LISTn in a couple places
 791         instead of scm_cons-ing by hand.
 792
 793         * __scm.h: Added SCM_ASSERT_TYPE macro.
 794
 795         * validate.h, scm_validate.h: Added the former, as a renamed
 796         version of the latter with SCM_ASSERT_TYPE used in
 797         SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
 798
 799         * Makefile.am: Rename scm_validate.h to validate.h.
 800
 801         * *.c, *.h: Include validate.h, not scm_validate.h (old name's
 802         prefix was superfluous).
 803
 804 Thu Mar  2 15:33:12 2000  Greg J. Badros  <gjb@cs.washington.edu>
 805
 806         * hashtab.c: Improved documentation for lots of functions.  Added
 807         handwritten docs for `hash-fold'.
 808
 809 Thu Mar  2 15:13:25 2000  Greg J. Badros  <gjb@cs.washington.edu>
 810
 811         * list.c: Added hand-written docs for `del{q,v,ete}1!'.
 812
 813 Thu Mar  2 12:38:30 2000  Greg J. Badros  <gjb@cs.washington.edu>
 814
 815         * list.c: Moved append docs to append! Thanks Dirk Hermann.  Also,
 816         added append docs from R4RS.
 817
 818         * strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
 819         Thanks Dirk Hermann!
 820
 821         * chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
 822         deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR.  Thanks Dirk Hermann!
 823
 824         * *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
 825         Drop use of SCM_P for function prototypes... assume an ANSI C
 826         compiler.  Thanks Dirk Hermann!

 828 Sat Feb 19 12:20:12 2000  Greg J. Badros  <gjb@cs.washington.edu>
 829
 830         * ports.c: Made `set-port-column!' and `set-port-line!' each
 831         return SCM_UNSPECIFIED instead of a (not-scheme-object) integer
 832         that caused a seg fault.  Also fixed `set-port-column!'s
 833         docstring.  Thanks Han-Wen Nienhuys for finding the bug!

 835 Sun Feb 13 19:11:42 2000  Greg J. Badros  <gjb@cs.washington.edu>
 836
 837         * arbiters.c, eq.c, gc.c, guardians.c, list.c, ports.c, print.c,
 838         regex-posix.c, scmsigs.c, stime.c, strings.c, variable.c, stime.c,
 839         strings.c, variable.c:  Added lots of documentation, cleaned up
 840         some existing documentation.  Occasionally changed formal params
 841         to match docs.  Also folded an #ifdef into the inners of a
 842         primitive instead of having two copies of the primitive
 843         (`get-internal-real-time', from stime.c)
 844
 845 Sun Feb 13 18:12:19 2000  Greg J. Badros  <gjb@cs.washington.edu>
 846
 847         * ports.c: Added docs for primitives missing them.  Written by
 848         hand.
 849
 850 Sun Feb 13 09:40:36 2000  Greg J. Badros  <gjb@cs.washington.edu>
 851
 852         * guile-doc-snarf.in: Use ${AWK} -f guile-func-name-check, not
 853         just execing guile-func-name-check.  Thanks Michael Livshin!
 854
 855 Thu Feb 10 11:43:23 2000  Greg J. Badros  <gjb@cs.washington.edu>
 856
 857         * guile-snarf.awk.in: Tweak to work with Sun/HP awk, removed some
 858         dead code.  Patch from Michael Livshin.
 859
 860         * guile-doc-snarf.in: Tweak to work with Sun/HP sh.  Patch from
 861         Michael Livshin.
 862
 863 2000-02-09  Gary Houston  <ghouston@arglist.com>
 864
 865         * init.c (scm_init_standard_ports): when stdout is a tty, make the
 866         current-output-port unbuffered by default.  this is less confusing
 867         for interactive use.  it was line-buffered because of a
 868         performance problem with unbuffered ports, but I think it will be
 869         OK now.
 870
 871 2000-02-08  Gary Houston  <ghouston@arglist.com>
 872
 873         * __scm.h: don't define long_long or ulong_long if HAVE_LONG_LONGS
 874         is not defined.
 875
 876         * stime.c (scm_localtime, scm_mktime): if neither HAVE_TM_ZONE nor
 877         HAVE_TZNAME are defined, use an empty string instead of giving two
 878         spurious compile-time errors.
 879
 880 Tue Feb  8 13:57:46 2000  Greg J. Badros  <gjb@cs.washington.edu>
 881
 882         * ports.c: Doc patches from Richard Kim.  Pasted from MIT Scheme.
 883         Thanks Richard!

 885 Mon Feb  7 09:07:31 2000  Greg J. Badros  <gjb@cs.washington.edu>
 886
 887         * macros.c: Doc patches from Richard Kim.  Pasted from scm.texi.
 888
 889 Sun Feb  6 20:26:21 2000  Greg J. Badros  <gjb@cs.washington.edu>
 890
 891         * pairs.c: Doc patches from Richard Kim.  Pasted from MIT Scheme
 892         (which is GNU GPL'd).
 893
 894 2000-01-31  Gary Houston  <ghouston@arglist.com>
 895
 896         * strings.h: don't use SCM_P.  don't include <string.h>.
 897         * error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>.
 898
 899         * strings.c (scm_string_ref): make the 2nd argument compulsory.
 900         previously it defaulted to zero for no good reason that I can see.
 901         use a local variable for SCM_INUM (k).  replace
 902         SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
 903
 904         (scm_makfromstr): cosmetic changes.
 905
 906         (scm_string): Accept only chars in the list, not strings, for
 907         conformance to R5RS (particularly for list->string, which is
 908         supposed to be the inverse of string->list.)  remove
 909         SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
 910         scm_makstr handles the cell allocation.  when reporting wrong-type
 911         arg, don't report the position as 1.
 912
 913         * posix.c (scm_init_posix): intern PIPE_BUF if it's defined.
 914
 915 2000-01-29  Gary Houston  <ghouston@arglist.com>
 916
 917         * posix.c (scm_pipe): rewrote the docstring.
 918
 919         * filesys.c (scm_select, retrieve_select_type, get_element,
 920         fill_select_type, set_element): modified so that Scheme
 921         "select" tests port buffers for the ability to provide input
 922         or accept output.  Previously only the underlying file descriptors
 923         were checked.  Rewrote the docstring.
 924
 925 Thu Jan 27 10:14:25 2000  Greg J. Badros  <gjb@cs.washington.edu>
 926
 927         * vectors.c, symbols.c, strorder.c: Documentation cut and pasted
 928         from Gregg Reynolds.  Thanks Gregg!
 929
 930 Thu Jan 27 09:59:38 2000  Greg J. Badros  <gjb@cs.washington.edu>
 931
 932         * strop.c (scm_i_index): Obfuscated commented-out SCM_DEFINE by
 933         adding "x" prefix to the line so that guile-func-name-check
 934         doesn't complain unnecessarily.
 935
 936 Wed Jan 26 17:33:52 2000  Greg J. Badros  <gjb@cs.washington.edu>
 937
 938         * throw.c: Factor out an #ifdef/#else/#endif choice more finely
 939         for maintainability.
 940
 941         * strop.c: Documentation added by Gregg A. Reynolds.   Pasted in
 942         from qdocs, RnRs.
 943
 944 Wed Jan 26 10:02:11 2000  Greg J. Badros  <gjb@cs.washington.edu>
 945
 946         * tag.c:  Added doc for `tag', but mark as deprecated since Mikael
 947         suggests removing tag.c altogether (and using a new `class-of'
 948         instead).
 949
 950         * strings.c:  Added documentation from Gregg A. Reynolds.  Edited
 951         a bit by me to use FOO instead of @var{foo} and to have the
 952         summary come before preconditions on input.  Also dropped trailing
 953         (rnrs) note.
 954
 955         * gsubr.c: Do not use SCM_DEFINE for `gsubr-apply'. Register the
 956         function with scm_make_subr_opt w/ last arg of 0 so it is not
 957         visible at the Scheme level. Mikael says that this is the right
 958         thing because the first arg to the proc is the guts of a compiled
 959         closure and shouldn't be exposed to the Scheme level.
 960
 961 Tue Jan 25 17:15:47 2000  Greg J. Badros  <gjb@cs.washington.edu>
 962
 963         * sort.c: typo in comment fixed.
 964
 965         * keywords.c: Added documentation.
 966
 967         * guardians.c: Added documentation (could be better).
 968
 969         * gc.c: Added docs for gc-set-debug-check-freelist.
 970
 971         * eq.c: Added docs for eq?, eqv? equal? abridged from R4RS.
 972
 973         * boolean.c: Added docs for `not', `boolean?' (by hand).
 974
 975 Tue Jan 25 13:28:56 2000  Greg J. Badros  <gjb@cs.washington.edu>
 976

 979
 980 Mon Jan 24 17:50:20 2000  Greg J. Badros  <gjb@cs.washington.edu>
 981
 982         * variable.c, version.c:  Added documentation, written by hand
 983         since I could not find anything already written that was
 984         relevant.
 985
 986 2000-01-23  Gary Houston  <ghouston@arglist.com>
 987
 988         * filesys.c (scm_chown): omit port/fdes support if HAVE_FCHOWN is
 989         not defined (thanks to Richard Y. Kim).
 990
 991 Thu Jan 20 13:00:38 2000  Greg J. Badros  <gjb@cs.washington.edu>

 996
 997         * list.c: Put some variable initialization code at the point of
 998         declaration; Added a comment for list*; Formatting changes.
 999
1000         * load.c: use SCM_NNULLP to make sure the end of a list is not
1001         reached yet.
1002
1003 2000-01-18  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1004
1005         * backtrace.c (scm_display_error_message): Bugfix: Don't use
1006         result of scm_list_p as C boolean.
1007         (scm_display_error_message, scm_set_print_params_x): Use new
1008         validation macros. (Thanks to Dirk Herrmann.)
1009
1010         * net_db.c (scm_resolv_error): Cast result from hstrerror.
1011
1012         * strports.c (st_end_input): Inserted parenthesis to get operator
1013         grouping correct.
1014
1015         * list.h (scm_init_list): Removed SCM_P around prototypes.
1016

1018         filesys.c, posix.c: Converted docstrings to ANSI C format and
1019         escaped " occurring inside string literals.

1041
1042         * scm_validate.h: Added SCM_VALIDATE_ULONG_COPY,
1043         SCM_VALIDATE_LONG_COPY
1044
1045         * numbers.c: Use SCM_VALIDATE_ULONG_COPY, instead of
1046         SCM_VALIDATE_INUM_COPY to let bigger numbers be used.  Rename a
1047         couple of formal arguments (and fix their uses) to make arguments
1048         match the documentation.
1049
1050 2000-01-14    <mstachow@alum.mit.edu>
1051
1052         * Makefile.am: Augment path when running guile-doc-snarf so
1053         guile-func-name-check is found.
1054
1055 Fri Jan 14 09:34:55 2000  Greg J. Badros  <gjb@cs.washington.edu>
1056
1057         * scm_validate.h (SCM_NUM2LONG_DEF): Fix this macro to just use
1058         def, not SCM_MAKINUM(def);  thanks Janis Bzerins!
1059
1060 Wed Jan 12 00:06:53 2000  Greg J. Badros  <gjb@cs.washington.edu>
1061
1062         * net_db.c (s_scm_inet_makeaddr): Use SCM_NUM2ULONG since that's
1063         the way guile-1.3.4 worked, but #if 0 out the version using
1064         SCM_VALIDATE_INUM_COPY for stricter testing.
1065
1066 Tue Jan 11 18:24:18 2000  Greg J. Badros  <gjb@cs.washington.edu>
1067
1068         * guile-doc-snarf.in: Use new $fullfilename for running
1069         guile-func-name-check, and put "$fullfilename" and "$filename" in
1070         quotes at uses to make sure re-splitting on whitespace does not
1071         occur (so filenames w/ embedded whitespace would work okay, though
1072         I sure hope we never have to deal with that! :-) ).  Thanks to
1073         Mikael for pointing out the source_dir != build_dir was broken.
1074
1075 Tue Jan 11 17:42:40 2000  Greg J. Badros  <gjb@cs.washington.edu>
1076
1077         * scm_validate.h: Added SCM_NUM2LONG_DEF macro.  Make
1078         SCM_OUT_OF_RANGE use SCM_MAKINUM, not scm_long2num.  Added
1079         SCM_COERCE_ROSTRING macro.  Added SCM_VALIDATE_NONEMPTYLIST
1080         macro.  Fix SCM_VALIDATE_STRINGORSUBSTR macro to not use SLOPPY
1081         variants.
1082
1083         * ports.c (scm_port_closed_p): Validate that the arg is a PORT,
1084         then return whether it's an open port (was validating that it was
1085         an open port -- this was a bug I introduced back in December, but
1086         my careful reading of diffs caught it).
1087
1088         * numbers.c: Recombine the two conditional-compilation paths for
1089         all the log* primitives -- they were split based on #ifndef
1090         scm_long2num;  factored out a SCM_LOGOP_RETURN macro, and fixed
1091         some bugs and inconsistencies in the two sets of implementations.
1092         (scm_lognot) Fixed *atrocious* re-use of a SCM as an integer!
1093
1094         * ioext.c: Use SCM_ASSERT_RANGE in a couple places, and
1095         SCM_VALIDATE_INUM_COPY once where it should've been used.
1096
1097         * fluids.c (scm_internal_with_fluids): Use
1098         SCM_VALIDATE_LIST_COPYLEN.
1099
1100         * filesys.c: Use SCM_NUM2LONG instead of SCM_VALIDATE_INUM_COPY;
1101         this is questionable as it relaxes type safety, but other changes
1102         were useful and all SCM_NUM2LONG's should probably be
1103         revisited. Use SCM_OUT_OF_RANGE, SCM_WRONG_TYPE_ARG.
1104
1105         * evalext.c: line-break change on 1 line.
1106
1107         * eval.c (nconc2last): Takes a non-empty list as its first
1108         argument, not just a list.
1109
1110         * dynl.c: Use new SCM_COERCE_ROSTRING macro.
1111
1112 Tue Jan 11 15:44:23 2000  Greg J. Badros  <gjb@cs.washington.edu>
1113
1114         * dynl.c, feature.c, filesys.c, fports.c, list.c, load.c,
1115         net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
1116         where possible.
1117
1118         * symbols.c (scm_sysintern0): Fixed the function name in a
1119         scm_misc_error invocation.
1120
1121         * print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
1122         use scm_return_first to ward off latent GC bug that Mikael caught.
1123
1124         * async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
1125         used before but should've been.
1126
1127 2000-01-12  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
1128
1129         * snarf.h (SCM_PROC1): Replaced SCM (*) (...) with
1130         SCM_FUNC_CAST_ARBITRARY_ARGS.
1131
1132 Tue Jan 11 13:44:07 2000  Greg J. Badros  <gjb@cs.washington.edu>
1133
1134         * guile-func-name-check.in: Added this script to statically check
1135         #define FUNC_NAME, #undef FUNC_NAME in the source.
1136
1137         * sort.c, posix.c: Fix #undef FUNC_NAME lines to not have trailing
1138         redundant comment, semicolon; caught by new guile-func-name-check
1139         script.
1140
1141         * debug.c: Fix mistaken #define FUNC_NAME for scm_make_iloc.
1142         Caught by new guile-func-name-check-script.
1143
1144         * Makefile.am: Added guile-func-name-check to bin_SCRIPTS
1145
1146         * ramap.c: Fix #if 0'd out code to be syntactically acceptable to
1147         guile-func-name-check.
1148
1149         * guile-doc-snarf.in: Run guile-func-name-check on the file before
1150         doing the snarf.
1151
1152 Tue Jan 11 11:31:10 2000  Greg J. Badros  <gjb@cs.washington.edu>
1153
1154         * fports.c, ports.c, ports.h, strports.c, vports.c: Make write
1155         port function take const void*, not void*.
1156
1157 Tue Jan 11 11:18:07 2000  Greg J. Badros  <gjb@cs.washington.edu>
1158
1159         * scm_validate.h, chars.c, ports.c, print.c, read.c, strings.c,
1160         strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
1161         SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY.  Change made for
1162         consistency with the other macros dealing with immediate
1163         characters.  (Similar to INT -> INUM change a week or so ago).
1164
1165 Tue Jan 11 10:41:46 2000  Greg J. Badros  <gjb@cs.washington.edu>
1166
1167         * dynl.c, error.c, eval.c, feature.c, filesys.c, fports.c, list.c, load.c,
1168         net_db.c, read.c, socket.c: Update error messages to use ~A for
1169         %s, ~S for %S to work with new `simple-format' format and be
1170         standardized better.
1171
1172         * print.h, print.c (scm_simple_format): Added `simple-format'
1173         primitive.  It's the old scm_display_error, with ARGS now a rest
1174         parameter, and the destination first instead of last (and a couple
1175         new capabilities inspired by `format' -- #t as destination means
1176         current-output-port, #f means return the formatted text as a
1177         string.
1178
1179         * gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
1180
1181         * backtrace.c (scm_display_error_message): Rewrote to use
1182         scm_simple_format() procedure.
1183
1184         * __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
1185
1186 2000-01-09  Marius Vollmer  <mvo@zagadka.ping.de>
1187
1188         Finally applied the libltdl patch from Thomas Tanner, with slight
1189         modifications.
1190
1191         * DYNAMIC-LINKING: Removed because it is obsolete.
1192         * dynl.c: Use ANSI prototypes.
1193         (sysdep_dynl_link): Use lt_dlopenext instead of lt_dlopen.
1194         * scmconfig.h.in: Do not change, as it is automatically generated.
1195
1196     1999-07-25  Thomas Tanner  <tanner@ffii.org>
1197
1198             * dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c: deleted
1199             (obsolete)
1200             * Makefile.am: likewise, add INCLTDL (libltdl headers) to
1201             INCLUDES, set dlpreopened files in LDFLAGS, link libguile
1202             against libltdl
1203             * dynl.c: use libltdl if DYNAMIC_LINKING is enabled,
1204             * guile.c: register preloaded modules
1205             * scmconfig.h.in: remove obsolete symbols
1206
1207 2000-01-09  Gary Houston  <ghouston@arglist.com>
1208
1209         * These changes should make it unnecessary to call tzset from
1210         Scheme after modifying the TZ environment variable, even if the
1211         system date facilities cache the value.
1212         * stime.c (setzone, scm_localtime): added comments.
1213         (tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
1214         (setzone): don't call tzset.
1215         (restorezone): call tzset only if HAVE_TZSET is defined.
1216         (scm_tzset): don't define if HAVE_TZSET not defined.  Change the
1217         doc string to indicate that this procedure isn't likely to do
1218         anything useful.
1219         (scm_localtime, scm_strftime, scm_mktime): call tzset if
1220         LOCALTIME_CACHE is defined.
1221
1222 2000-01-09  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
1223
1224         * posix.c (scm_sync): Return SCM_UNSPECIFIED.
1225
1226 2000-01-09  Gary Houston  <ghouston@arglist.com>
1227
1228         * eval.c: define scm_unbound_variable_key ('unbound-variable).
1229         scm_lookupcar1: throw an error with key 'unbound-variable instead
1230         of 'misc-error when an unbound variable is encountered.
1231
1232         * filesys.c (scm_mkdir, scm_rmdir, scm_getcwd, scm_select,
1233         scm_symlink, scm_readlink, scm_lstat),
1234         posix.c (scm_setpgid, scm_setsid, scm_ctermid, scm_tcgetpgrp,
1235         scm_tcsetpgrp, scm_uname, scm_setlocale, scm_mknod, scm_nice,
1236         scm_sync),
1237         simpos.c (scm_system),
1238         stime.c (scm_times, scm_strptime):
1239         move the HAVE_XXX feature tests out of the procedure bodies.
1240         don't use SCM_SYSMISSING.
1241         scm_validate.h (SCM_SYSMISSING): removed.
1242         error.h, error.c (scm_sysmissing): comment that this is deprecated.
1243         see ChangeLog entry for 1999-12-28.
1244
1245 Sat Jan  8 19:52:04 2000  Greg J. Badros  <gjb@cs.washington.edu>
1246
1247         * scm_validate.h (SCM_VALIDATE_BOOL_COPY): Fix typo.
1248
1249 Sat Jan  8 17:06:46 2000  Greg J. Badros  <gjb@cs.washington.edu>
1250
1251         * backtrace.c: Fix spelling typo in a comment.
1252
1253         * snarf.h: Use new SCM_DOCS macro to encapsulate the non SCM_INIT
1254         text.  Reformatted some of the expansions.
1255
1256 Fri Jan  7 15:50:46 2000  Greg J. Badros  <gjb@cs.washington.edu>
1257
1258         * scm_validate.h (SCM_OUT_OF_RANGE): Use scm_out_of_range_pos to
1259         report the position of the argument.
1260
1261         * error.h, error.c (scm_out_of_range_pos):  Added this function to
1262         take extra "pos" argument, the position number of the errant
1263         argument.
1264
1265         * debug.c: Use SCM_OUT_OF_RANGE instead of scm_out_of_range.
1266
1267         * snarf.h: Use SCM_HERE and SCM_INIT as names, not SCM_NOTSNARF
1268         and SCM_SNARFING.  Also put the %%% in the SCM_INIT since Mikael
1269         prefers that and I'm reasonably indifferent.
1270
1271 Fri Jan  7 15:03:32 2000  Greg J. Badros  <gjb@cs.washington.edu>
1272
1273         * snarf.h: Factor out differences between C++ and non-C++ into
1274         SCM_FUNC_CAST_ARBITRARY_ARGS macro.  Modify all the snarf macro
1275         definitions to use SCM_NOTSNARF and SCM_SNARFING macros (like
1276         Mikael's macros, below, but changed names and SCM_SNARFING no
1277         longer expands to include %%% -- that must appear in the argument
1278         so that the token appears at the call-site as a reminder).
1279
1280 2000-01-07  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
1281
1282         * snarf.h (SCM_INSITU, SCM_INIT): New snarf macros for use in user
1283         snarf macro definitions.
1284
1285 2000-01-06  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1286
1287         * chars.c (scm_integer_to_char): Use Greg's nice
1288         SCM_VALIDATE_INUM_RANGE macro for argument checking for closer
1289         adherence to R5RS.
1290
1291 Thu Jan  6 11:48:49 2000  Greg J. Badros  <gjb@cs.washington.edu>
1292
1293         * *.c, snarf.h: Replace GUILE_PROC1 with SCM_DEFINE1 throughout.
1294
1295 Thu Jan  6 11:22:53 2000  Greg J. Badros  <gjb@cs.washington.edu>
1296
1297         * Makefile.am (ETAGS_ARGS): Switch to SCM_DEFINE, SCM_DEFINE1
1298         instead of GUILE_PROC.
1299
1300 Thu Jan  6 11:21:49 2000  Greg J. Badros  <gjb@cs.washington.edu>
1301
1302         * alist.c: Do not report mismatch errors on some uses of `tmp' (do
1303         this by using SCM_ARG2 instead of `2' in the SCM_VALIDATE_CONS
1304         macro call.
1305
1306 Thu Jan  6 09:54:33 2000  Dirk Herrmann <dirk@ida.ing.tu-bs.de> --gjb applied
1307
1308         * scm_validate.h: Remove some redundant NIMP tests.
1309
1310         * alist.c: minimize scope of the tmp variables, and initialize
1311         them when declared. The strange SCM_NIMP tests are replaced by
1312         SCM_CONSP tests that more closely reflect the intended semantics.
1313         However, we don't get a performance penalty here, because the
1314         SCM_CONSP test was performed by the ALISTCELL test anyway.  * The
1315         extremely ugly use of ASRTGO macros was removed: The calls to
1316         ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a
1317         label parameter that only exists when SCM_RECKLESS is not defined.
1318         This works, because ASRTGO itself is defined in a way that it only
1319         makes use of the label parameter if SCM_RECKLESS is not defined
1320         (shudder!).  Does guile make at all use of the possibility to
1321         define SCM_RECKLESS?  * Codesize is likely to be reduced, since
1322         instead of two calls to SCM_ASSERT performed by the ALISTCELL test
1323         we now only get one test.
1324
1325         * list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate.  Also use
1326         SCM_NULLP instead of SCM_IMP.  Drop use of "register" keyword on
1327         some variables in `list?'.  Fix `reverse' and `reverse!'
1328         primitives to handle improper lists better.
1329
1330 Wed Jan  5 11:24:53 2000  Greg J. Badros  <gjb@cs.washington.edu>
1331
1332         * *.[ch]: Whitespace changes -- added space after SCM_VALIDATE_*
1333         macros and SCM_DEFINE macros to match GNU coding standards.
1334
1335 Wed Jan  5 11:04:24 2000  Greg J. Badros  <gjb@cs.washington.edu>
1336
1337         * *.[ch]: Replace GUILE_PROC w/ SCM_DEFINE.
1338
1339 Wed Jan  5 10:59:06 2000  Greg J. Badros  <gjb@cs.washington.edu>
1340
1341         * *.[ch]:  Replace SCM_VALIDATE_INT w/ SCM_VALIDATE_INUM for
1342         better consistency with the names of other SCM_VALIDATE_ macros
1343         and better conformance to guile naming policy.
1344
1345 Wed Jan  5 10:50:39 2000  Greg J. Badros  <gjb@cs.washington.edu>
1346
1347         * ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a
1348         SCM_VALIDATE instead of 1 to avoid a check on the argument (since
1349         it's not the actual name of the formal).
1350
1351         * guile-snarf.awk.in: Do argument/number mismatch checking and
1352         print warnings in an Emacs compile-mode parseable format.
1353
1354         * struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/
1355         SCM_OUTOFRANGE as 3rd argument.
1356
1357         * random.c: Fix argument/number mismatch (that I introduced :-( ).
1358
1359         * __scm.h: Do not #define SCM_ARG* when snarfing;
1360         lets us distinguish between 1 and SCM_ARG1 when snarfing as only
1361         the former (using the number) requires the argument to match the
1362         formal in the current argument snarfing check.
1363
1364         * snarf.h: Give new definition of SCM_ASSERT when in
1365         snarfing mode to output a lexically-identifiable sequence that the
1366         guile-snarf.awk script uses to verify argument/position matching.
1367
1368         * ramap.c: Remove extraneous #undef FUNC_NAME.
1369

1372         * guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the
1373         current version of the same functionality; it writes the .x output
1374         to stdout instead of directly into the file.
