  23         declare functions with prototypes.  (Patch thanks to Marius
  24         Vollmer.)
  25
  26         More prototype-related changes from Marius Vollmer:
  27         * gdb_interface.h: Wrapped header file in #ifdef/#endif
  28         * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
  29         * ports.h (ptobfuns): Added prototypes. This means some casting in
  30         fports.c.
  31         * fports.c: Added casts for initializations, since the functions
  32         are defined to take FILE * as their stream argument, not SCM.
  33         * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
  34         * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
  35         to `char *str_data' to conform to prototype.
  36
  37 Sat Oct 12 21:49:29 1996  Gary Houston  <ghouston@actrix.gen.nz>
  38
  39         * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
  40
  41         * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
  42
  43         * stime.c, stime.h: use SCM_P method.
  44
  45 Sat Oct 12 16:16:25 1996  Jim Blandy  <jimb@floss.cyclic.com>
  46
  47         * eval.c (scm_nconc2last): Don't accept an empty list; apply must
  48         be given at least two arguments.  Insist that lst's last element
  49         be a list, but don't make any requirements of its predecessors.
  50
  51 Fri Oct 11 03:58:25 1996  Jim Blandy  <jimb@floss.cyclic.com>
  52
  53         * eval.c (scm_nconc2last): Revert last change; there seems to be
  54         other stuff going on here.
  55
  56 Fri Oct 11 02:43:59 1996  Jim Blandy  <jimb@totoro.cyclic.com>
  57
  58         * eval.c (scm_nconc2last): Make sure that each element of lst
  59         (which is a list of argument lists, except for the tail) is a
  60         proper list, i.e., finite and terminated by '().
  61
  62 Thu Oct 10 21:09:13 1996  Jim Blandy  <jimb@totoro.cyclic.com>
  63
  64         * unif.c (scm_ra_set_contp): Localize `inc' declaration.
  65         Clarifies flow.
  66
  67         * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
  68         symbolic name for the tag, scm_tc3_cons_gloc, instead of just
  69         saying "1".
  70
  71         * vectors.c (scm_make_vector): Fill vectors with the undefined
  72         value, to help make Guile Scheme code more portable to other
  73         Schemes.
  74
  75         * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
  76         * symbols.h, tags.h: Doc fixes.
  77
  78 Wed Oct  9 19:39:29 1996  Jim Blandy  <jimb@floss.cyclic.com>
  79
  80         * async.c (scm_take_signal): Doc fixes.
  81
  82 Mon Oct  7 22:30:34 1996  Jim Blandy  <jimb@totoro.cyclic.com>
  83
  84         * numbers.c (scm_divbigint): When the remainder is zero, we don't
  85         want to subtract it from the modulus; we just want to leave it
  86         alone.
  87
  88 Mon Oct  7 00:14:17 1996  Mikael Djurfeldt  <mdj@kenneth>
  89
  90         * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
  91         `scm_init_threads'.
  92
  93         * throw.h (scm_catch_apply): Removed the `lazyp' argument.
  94
  95         * throw.c (scm_catch_apply): Finished implementation of
  96         `lazy-catch'.
  97
  98 Sun Oct  6 05:26:05 1996  Gary Houston  <ghouston@actrix.gen.nz>
  99
 100         * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
 101         check.
 102         (scm_init_filesys): set "i/o-extensions" feature.
 103         include feature.h.
 104
 105 Sat Oct  5 12:22:00 1996  Jim Blandy  <jimb@floss.cyclic.com>
 106
 107         * Makefile.in (root.o): Correct dependencies.
 108
 109 Sat Oct  5 18:40:42 1996  Mikael Djurfeldt  <mdj@kenneth>
 110
 111         * Makefile.in: Added dependency entry for root.o.
 112
 113         * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
 114         throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
 115
 116         * init.c (scm_start_stack): Set initial root continuation number
 117         to 0.
 118
 119         * procs.c: New function: scm_thunk_p.
 120
 121         * procs.h: Added declarations of scm_thunk_p.
 122
 123         * root.c: Renamed `call-with-new-root' -->
 124         `call-with-dynamic-root'.
 125         (cwdr): Removed allocation of new root state.  This should be done
 126         separately by use of scm_make_root.
 127         (scm_apply_with_dynamic_root): New function: Does what it
 128         sounds like.  Needed when spawning threads.
 129
 130         * root.h: Added member last_debug_frame to root state.
 131         Added #include "libguile/debug.h"
 132
 133         * throw.c: Renamed scm_catch --> scm_catch_apply and added more
 134         arguments.  The motivation is that code in root.c needs catch
 135         functionality, and we want to avoid code duplication.
 136         New functions: scm_catch, scm_lazy_catch.  These are wrappers for
 137         scm_catch_apply.  scm_lazy_catch is intended to introduce catch
 138         handlers that run without popping the stack into the dynwind
 139         chain.
 140
 141         * throw.h: Added prototypes for scm_catch_apply and
 142         scm_lazy_catch.
 143
 144 Thu Oct  3 11:12:33 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 145
 146         * root.h (scm_root, scm_set_root): Decouple thread support details
 147         by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
 148         SCM_SET_THREAD_LOCAL_DATA.
 149
 150         * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
 151         and tortoise scanning loop.
 152
 153 Thu Oct  3 00:04:53 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 154
 155         * Makefile.in: Rebuild dependencies.
 156
 157         * libguile.h: #include "libguile/print.h" before "smob.h", since
 158         the latter uses the print_state structure.
 159
 160         * throw.c (scm_ithrow): Use the correct variable when checking to
 161         see if a given element of scm_dynwinds is a valid catch.
 162
 163         * throw.c (scm_ithrow): If scm_dynwinds has invalid list
 164         structure, abort; don't just silently ignore the garbage.
 165
 166         * _scm.h: #include "print.h" here, since it seems to be used just
 167         about everywhere.
 168         * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
 169         strports.c, unif.h: Don't #include "print.h".
 170
 171 Tue Oct  1 05:15:10 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 172
 173         * feature.h (scm_loc_features): Removed external declaration.
 174         (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
 175
 176 Tue Oct  1 00:00:10 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 177
 178         * feature.c (scm_init_feature): Added threads feature (needs to be
 179         initialized here, since features doesn't exist when
 180         scm_init_threads is called).
 181
 182         * libguile.h: Added #include "libguile/../threads/threads.h".
 183         (This is a kludge to get thread support working.  This should be
 184         fixed.)
 185
 186         * configure.in, acconfig.h: Added flags for thread support.
 187
 188         * scmsigs.c: Define `signal' to be `pthread_signal' if using
 189         mit-pthreads.
 190
 191         * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
 192         SCM_THREAD_CRITICAL_SECTION_END.  Moved marking of root data to
 193         root.c:mark_root.
 194
 195         * _scm.h: Added conditional #include "threads.h"
 196
 197         * __scm.h (SCM_ASYNC_TICK): Added call to macro
 198         SCM_THREADS_SWITCHING_CODE.
 199
 200         * init.c (scm_start_stack): Call `scm_make_root' to dynamically
 201         allocate the basic dynamic root object.
 202         (scm_boot_guile): Added call to scm_init_root.
 203
 204 *       * root.c, root.h: Added root smob.
 205         (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
 206         functions: Implements dynamic roots mostly according to spec in
 207         SCM manual.  Main difference is that the second argument is a
 208         throw handler rather than an error "thunk".
 209
 210         * root.h: Added declaration of scm_init_root.
 211
 212         * root.c: Added #include "genio.h", #include "smob.h", #include
 213         "pairs.h", #include "throw.h", #include "dynwind.h", #include
 214         "eval.h"
 215         (scm_init_root): Added #include "root.x".
 216
 217         * throw.c: Added #include "stackchk.h"
 218         (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
 219         SCM_ALLOW_INTS --> SCM_REALLOW_INTS.  This is so that scm_catch
 220         can be used in scm_call_with_new_root; Added reenabling of stack
 221         checking when catching a throw.
 222
 223 Mon Sep 30 21:48:11 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 224
 225         * list.c, list.h: Use SCM_P instead of CPP hair.  Doc fixes.
 226
 227         * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
 228         element is not found, as per R4RS.
 229
 230 Sat Sep 28 18:13:01 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 231
 232         * list.c: Doc fixes throughout.
 233
 234 Sat Sep 28 02:07:43 1996  Gary Houston  <ghouston@actrix.gen.nz>
 235
 236         * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
 237         declare the char * to be const.  Avoids a warning in rgx.c.
 238
 239         * ports.h: spelling fix.
 240
 241         * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
 242         error messages.
 243
 244         * load.c (scm_sys_try_load_path): throw an error if file not found
 245         (like it says it in NEWS).
 246
 247 Fri Sep 27 18:27:01 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 248
 249         * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
 250         PROPS slot to '(), not #f; it's an empty alist.
 251
 252         * throw.h, throw.c: Use SCM_P instead of #if hair.
 253
 254         Remove special support for uncaught throws; see throw.c for
 255         rationale.
 256         * throw.c (uncaught_throw): New function.
 257         (scm_ithrow): Call uncaught_throw if we don't find a throw
 258         target; don't mess with scm_bad_throw_vcell.
 259         (scm_bad_throw_vcell): Variable deleted.
 260         (scm_init_throw): Don't initialize it.
 261
 262         * throw.c (scm_ithrow): Don't let outer key matches shadow inner
 263         #t catches.
 264
 265 Wed Sep 25 04:35:50 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 266
 267         * numbers.c (scm_istr2int): If the number is short (as most
 268         numbers are), just call scm_small_istr2int to deal with it.
 269         (scm_small_istr2int): New function, created by un-#ifdefing the
 270         non-bignum version of scm_istr2int and renaming it.
 271
 272 Tue Sep 24 06:48:38 1996  Gary Houston  <ghouston@actrix.gen.nz>
 273
 274         * load.c (scm_sys_try_load): don't check whether value returned
 275         by scm_open_file is #f, it won't be.  Always return SCM_UNSPECIFIED.
 276         Change the Scheme name from %try-load to primitive-load.
 277
 278         * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
 279         Can avoid passing a message, allowing it to be derived in the
 280         error handler (e.g., if we want to throw to the key both from
 281         Scheme and C).
 282
 283 Mon Sep 23 00:42:15 1996  Mikael Djurfeldt  <mdj@kenneth>
 284
 285 *       * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
 286         references now have a new appearance which is more compact and
 287         also gives a clue about what the target of the reference is.
 288         By setting parameters in the print state, more fancy printing can
 289         be achieved.  This is used by the (not yet commited) backtrace
 290         code.
 291
 292 Sun Sep 22 17:10:06 1996  Mikael Djurfeldt  <mdj@kenneth>
 293
 294         * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
 295         "print.h"
 296
 297         * print.c: Added #include "struct.h".  Removed function
 298         scm_prlist.
 299
 300         * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
 301         scm_iprin1.  Removed prototype for scm_prlist.
 302
 303         * arbiters.c (prinarb),
 304         async.c (print_async),
 305         debug.c (prindebugobj, prinmemoized),
 306         eval.c (prinprom, prinmacro),
 307         filesys.c (scm_fd_print, scm_dir_print),
 308         kw.c (print_kw),
 309         mallocs.c (prinmalloc),
 310         numbers.c, numbers.h (scm_floprint, scm_bigprint),
 311         smob.h (scm_smobfuns),
 312         srcprop.c (prinsrcprops),
 313         throw.c (prinjb),
 314         unif.c, unif.h (scm_raprin1, rapr1),
 315         variable.c (prin_var): Changed argument `int writing' to
 316         `scm_print_state *pstate'.
 317
 318         * init.c (scm_boot_guile): Moved scm_init_struct upwards so
 319         that it will be called before scm_init_print.
 320
 321         * print.c (scm_prin1): Print states are now allocated when calling
 322         scm_prin1 and then passed around to all printing functions as an
 323         argument.  A cache `print_state_pool' enables reuse of print
 324         states.
 325         (scm_make_print_state): New function.
 326         (scm_iprin1): Adaption to print states.
 327         (scm_iprlist): An initial "hare and tortoise" scan brings down
 328         time complexity to O (depth * N).  (Better time complexity will be
 329         achieved when the printing code is completely rewritten.)
 330
 331 Fri Sep 20 22:01:36 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 332
 333         * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
 334         AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
 335         it gets done whether or not the cache variable has a value.
 336
 337 Thu Sep 19 17:06:39 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 338
 339         Distinguish #f and ().
 340         * __scm.h: #undef SICP.
 341         * pairs.h (SCM_EOL): Delete this definition, equating it with
 342         SCM_BOOL_F.
 343         * tags.h (SCM_EOL): Give it a new definition here; I think I found
 344         the value it used to have.  Doc fixes, too.
 345
 346 Thu Sep 19 15:33:51 1996  Mikael Djurfeldt  <mdj@kenneth>
 347
 348         * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
 349         scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
 350         Lord's implementation of structs, allowing for tail arrays as
 351         described in the manual. Also fixed some bugs. (Both the interface
 352         and the implementation should be improved.)
 353
 354         * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
 355
 356         * print.c, print.h: Closures now print like #<procedure foo (x)>.
 357         People who whish to see the source can do `(print-enable 'source)'.
 358         Removed #ifdef DEBUG_EXTENSIONS.
 359
 360 Thu Sep 19 00:00:29 1996  Gary Houston  <ghouston@actrix.gen.nz>
 361
 362         * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
 363         integer (assuming for now accepting an integer is a good thing).
 364
 365         * error.c, fports.c: replace use of %S in lgh_error args with %s.
 366         %S will be used instead for write'ing arguments.
 367
 368         * unif.c (scm_transpose_array): change arguments in the SCM_WNA
 369         asserts.  fix a few other asserts.

 371         scm_uniform_vector_ref, scm_array_set_x,
 372         scm_dimensions_to_unform_array): change args in
 373         SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
 374         strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
 375         scm_substring_fill_x): likewise.
 376         gsubr.c (scm_gsubr_apply): likewise.
 377         eval.c (SCM_APPLY): likewise.
 378
 379         * eval.c (4 places): replace scm_everr with lgh_error or
 380         scm_wrong_num_args.
 381
 382         * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
 383         scm_memory_error): new procedures.
 384 *       scm_everr: deleted.  can use scm_wta, dropping first two args.
 385         scm_error: convert NULL subr to SCM_BOOL_F.
 386
 387         * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
 388         SCM_ARGERR.
 389
 390         * stackchk.c (scm_report_stack_overflow): use lgh_error instead
 391         of scm_wta.
 392
 393         * error.c, error.h: new error keys: scm_arg_type_key,
 394         scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
 395         scm_misc_error_key.
 396         scm_wta: reimplement using lgh_error instead of scm_everr.
 397
 398 Wed Sep 18 17:13:35 1996  Mikael Djurfeldt  <mdj@kenneth>
 399
 400         * gdbint.c: scm_lread now has one more argument.
 401
 402         * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
 403         scm_port_\1; Added mutator scm_set_port_filename_x (used when
 404         loading source from non-file ports, which, e. g., happens when
 405         using the Emacs interface).
 406
 407         * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
 408         object.
 409
 410         * read.c: Added code for recording of positions of source code
 411         expressions; New functions: recsexpr, scm_lreadrecparen;
 412         _scm_make_srcprops --> scm_make_srcprops
 413         (scm_flush_ws): Removed updating of positions counters.  This work
 414         is already done by scm_gen_getc
 415
 416         * read.h: Added prototype for scm_lreadrecparen
 417
 418         * print.c: Added #include "alist.h"
 419
 420         * eval.c: Added #include "hash.h"
 421
 422         * eq.c: Added #include "ramap.h"
 423
 424         * options.c: Documentation fixes.
 425
 426         * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
 427         (scm_init_srcprop): Adjusted size of initial source-whash.  Name
 428         changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
 429         --> scm_make_srcprops
 430
 431         * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
 432         _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
 433         function calls in the definition of the whash access macros.
 434
 435 Tue Sep 17 11:33:16 1996  Lee Iverson  <leei@Canada.AI.SRI.COM>
 436
 437         * init.c (scm_boot_guile): Add level of indirection to
 438         scm_boot_guile_1() to ensure that stack base pointer is properly
 439         initialized.  There was no guarantee that variable i was the
 440         highest/lowest variable on stack (i.e. the call frame of
 441         scm_boot_guile was not completely protected from gc).
 442
 443 Tue Sep 17 01:40:56 1996  Gary Houston  <ghouston@actrix.gen.nz>
 444
 445         * ports.h (scm_port_table): put back file_name, it will be used to
 446         support debugging.  Undo related changes in fports.c, ioext.c,
 447         ports.c, gc.c.
 448
 449 Sun Sep 15 03:58:29 1996  Gary Houston  <ghouston@actrix.gen.nz>
 450
 451         * ports.h (scm_port_table): remove file_name member for now, it seems
 452         undesirable.
 453         * fports.c (scm_open_file): don't set file_name in PTAB.
 454         (prinfport): don't use file_name in PTAB.
 455         * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
 456         * ports.c (scm_add_to_port_table): don't intialize file_name.
 457         (scm_port_file_name): remove for now.
 458         * gc.c (scm_gc_mark): don't mark PTAB file_name.
 459
 460         * fports.h (scm_mkfile): prototype deleted.
 461         * fports.c (scm_mkfile): merged into scm_open_file to simplify.
 462
 463         * debug.c, unif.c: use scm_out_of_range instead of
 464         wta for range errors (ASSERT still needs work).
 465
 466         * error.c, error.h (scm_out_of_range): new procedure.
 467
 468         * error.c, error.h (scm_out_of_range_key): new key.
 469
 470         * posix.c (scm_sync): #else was missing.
 471
 472         * error.c, error.h: append _key to names scm_num_overflow and
 473         scm_system_error.
 474
 475         * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
 476         of consing an empty list.
 477         (SCM_SYSERROR etc.): move into error.c, make them procedures instead
 478         of macros, saves code and string space.
 479         error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
 480         fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
 481         lower case.  Rename scm_syserror_m to scm_syserror_msg.
 482         error.h: prototypes for new procedures.
 483
 484 Sat Sep 14 03:35:41 1996  Gary Houston  <ghouston@actrix.gen.nz>
 485
 486         * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
 487
 488         * error.c, error.h: setup scm_num_overflow key.
 489
 490         * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
 491         Remove definition of SCM_OVSCM_FLOW.
 492
 493         * fports.c (scm_open_file): use SCM_SYSERROR_M.
 494
 495         * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
 496         explicit message and args.
 497
 498         * error.c, error.h, __scm.h: change system_error_sym to
 499         scm_system_error.
 500
 501         * error.c (system_error_sym): remove leading %% from the Scheme name
 502         "%%system-error".
 503
 504         * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
 505
 506 Fri Sep 13 12:58:08 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 507
 508         * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
 509         fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
 510         numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
 511         tags.h, throw.c, variable.h: Name cleanup.  Lots of xxxSCM_yyy
 512         renamed.  (These were introduced by unsupervised name
 513         substitution.)
 514
 515 Fri Sep 13 01:19:08 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 516
 517 *       * print.c: Added code for detection of circular references during
 518         printing.  (init_ref_stack, grow_ref_stack): New functions.  Added
 519         a hook for printing of closures (accessible via print options).
 520         This leads to a split of calls to scm_iprin1 into two classes:
 521         elementary print operations (e. g. the code which prints a smob)
 522         still use scm_iprin1 while top level calls (like scm_display) use
 523         scm_prin1.  scm_prin1 begins by clearing the data structure used
 524         to record reference information.
 525
 526         * print.h: Added declarations of scm_prin1 and scm_prlist.
 527
 528         * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
 529
 530         * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
 531
 532         * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
 533
 534         * error.c (err_head): scm_iprin1 --> scm_prin1
 535
 536         * debug.c: Adjusted header comment.
 537
 538         * tags.h: Typo.
 539
 540 Wed Sep 11 17:55:59 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 541
 542         * strerror.c: Doc fix.
 543
 544 Thu Sep 12 00:00:32 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 545
 546         * gdbint.c (gdb_read): Now possible to run during GC.
 547         (unmark_port, remark_port): New functions.
 548
 549         * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
 550
 551         * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
 552         of allocating a new string object.  Also, increase size by
 553         the factor 2 instead of 1.5.
 554
 555 Wed Sep 11 15:10:38 1996  Petr Adamek  <jimb@floss.cyclic.com>
 556
 557         * __scm.h (SCM_P): Corrected to run under traditional C.
 558
 559         * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
 560         removed.
 561
 562         * async.c: Calls to scm_sysintern corrected.
 563
 564         * async.h (scm_async_clock): Redundant declaration removed.
 565
 566         * continuations.c (scm_dynthrow): Redundant declaration removed.
 567
 568         * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
 569         Definition typos corrected.
 570
 571         * debug.h: Missing declarations of functions in debug.c added
 572         (lots).
 573
 574         * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
 575         Missing declarations to functions in eval.c added.
 576
 577         * filesys.c: Possibly uninitialized variable rv.
 578
 579         * gc.h (scm_object_addr, scm_unhash_name): Missing
 580         declarations of functions defined in gc.c added.
 581
 582         * genio.c: Possible typos str_data -> wstr_data. ???
 583
 584         * genio.c: Possibly unintended shadowing of local variable
 585         `int c' (gotos out of scope of inner `c'). ???
 586
 587         * init.c: Uninitialized `SCM last' may be used.
 588
 589         * ioext.h: (scm_sys_isatty_p): Typo.
 590
 591         * list.h (scm_list_head): Missing prototype for function in
 592         list.c added.
 593
 594         * numbers.c (scm_two_doubles): Changed from extern to static
 595         (is used only within numbers.c).
 596
 597         * numbers.h: Repeated declarations removed.
 598
 599         * ports.h (scm_close_all_ports_except): Declaration for the
 600         function defined in ports.c added.
 601

 609
 610         * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
 611         Missing declarations added.
 612
 613         * stime.h (scm_get_internal_real_time): Repeated declarations removed.
 614
 615         * struct.c: Uninitialized variable `SCM answer' may be used.
 616
 617         * unif.c (l2ra): Declaration prototype.
 618
 619         * unif.c (scm_array_equal_p): Dummy definition removed (it is
 620         defined in ramap.c).
 621
 622         * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
 623         Redundant declarations removed (they are in ramap.h).
 624
 625         * variable.h (scm_make_udvariable,
 626         scm_make_undefined_variable): Declaration corrected to
 627         correspond variable.c.

 633
 634         * Makefile.in (distclean): Don't forget to delete fd.h.
 635
 636 Tue Sep 10 14:01:46 1996  Jim Blandy  <jimb@floss.cyclic.com>
 637
 638         * fd.h.in, tags.h: Trivial cleanups.
 639
 640         * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
 641         marksweep.h just declared functions from gc.c.
 642         * gc.h, libguile.h: Don't #include "marksweep.h".
 643         * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
 644         marksweep.o, marksweep.h, marksweep.c, and marksweep.x.  Other
 645         dependencies updated.
 646
 647         * libguile.h: Don't #include "files.h"; it's been deleted.
 648
 649         * files.c (scm_sys_delete_file): Moved to filesys.c.
 650         File is now empty; deleted.
 651         * files.h: Deleted.
 652         * filesys.c: scm_sys_delete_file is now here.  Remove
 653         #if's; they seem to rely on remnants of an old portability
 654         regimen.  If the problems come up again, solve them properly,
 655         using autoconf.  Specifically: Don't test M_SYSV, and #define
 656         remove to be unlink if it's #defined; don't use remove just
 657         because HAVE_STDC_HEADERS is #defined.
 658         * filesys.h: Add declarations for scm_sys_delete_file.
 659         * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
 660         files.o, files.h, files.c, and files.x.
 661         * init.c: Don't #include "files.h", and don't call scm_init_files.
 662
 663         Use SCM_P instead of PROTO; the latter intrudes on the user's
 664         namespace.
 665         * params.h: Deleted; definition of SCM_P moved to...
 666         * __scm.h: ... here, where it replaces PROTO macro.
 667         * libguile.h, smob.h: Don't #include "params.h".
 668         * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
 669         smob.h: Fix prototypes accordingly.
 670         * Makefile.in: Update dependencies.
 671         (inner_h_files): Remove params.h.
 672
 673         * gc.c: #include "gc.h"; every module should include its header,
 674         to let the compiler cross-check the declarations against the
 675         definitions.
 676
 677         * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
 678         simpos.h: #include "libguile/__scm.h".
 679
 680 Mon Sep  9 20:00:15 1996  Jim Blandy  <jimb@floss.cyclic.com>
 681
 682         * init.c: Don't forget to #include smob.h and init.h.
 683         * Makefile.in: Dependencies updated.
 684
 685         * smob.h: Use PROTO instead of #if __STDC__.
 686
 687         * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
 688
 689         * __scm.h: Doc fixes.
 690
 691         * __scm.h, libguile.h: Use "quotes" in the #includes, not
 692         <angles>; this allows `make depends' to work properly.
 693
 694         * libguile.h: #include smob.h and pairs.h before the others; they
 695         define typedefs used by other headers.
 696
 697         C files should #include only the header files they need, not
 698         libguile.h (which #includes all the header files); the pointless
 699         recompilation was wasting my time.
 700         * Makefile.in (all .o dependency lists): Regenerated.
 701         * libguile.h: Don't try to get a definition for size_t here...
 702         * __scm.h: Do it here.
 703         * _scm.h: Since this is the internal libguile header, put things
 704         here that all (or a majority) of the libguile files will want.
 705         Don't #include <libguile.h> here; that generates dependencies on
 706         way too much.  Instead, get "__scm.h", "error.h", "pairs.h",
 707         "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",

 805         * weaks.c: Get "weaks.h".
 806
 807         * stackchk.h: #include "libguile/debug.h",
 808
 809         * print.h, read.h: #include "options.h", since everyone who uses
 810         either of these files will need that.
 811
 812         * smob.h: #include "ports.h", "genio.h", and "print.h", since
 813         anyone who uses this file will need them to define the smob
 814         printing functions.  Also, get markers.h, since people will need
 815         to #define the mark functions.
 816
 817         * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
 818         * ports.h: ... to here.
 819
 820         * ports.h (scm_port_table_size): Explicitly give type as 'int';
 821         don't rely on archaic C default type rules.
 822
 823         * fports.h: #include "libguile/ports.h", since you need that in
 824         order to parse this.
 825
 826         * genio.h: #include "libguile/print.h", because you need that to
 827         parse this; don't bother #including "ports.h", since print.h gets
 828         that.
 829
 830         * error.h: Don't #include "pairs.h"; _scm.h will do that now.
 831
 832         * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
 833         this; it's now a reference to an element of *scm_root.
 834
 835         * debug.h: Don't #include "options.h"; the compiler won't be able
 836         to find that once the headers are installed; instead, #include
 837         "libguile/options.h".
 838         * gc.h: Same, with marksweep.h.
 839         * mbstrings.h: Same, with symbols.h.
 840         * scmhob.h: Same, with _scm.h.
 841         * smob.h: Same, with params.h.
 842
 843         * Makefile.in (depends): Don't nuke scmconfig.h and the generated
 844         C files; there's no need for this, and it forces recompilations
 845         unnecessarily.
 846
 847 Sat Sep  7 06:57:23 1996  Gary Houston  <ghouston@actrix.gen.nz>
 848
 849         * error.c (scm_error): declare scm_error_callback.
 850
 851         * error.h: prototype for scm_error_callback.
 852
 853         * __scm.h: define lgh_error.
 854         (SCM_SYSERROR): redefine using lgh_error.

 856 Thu Sep  5 22:40:06 1996  Gary Houston  <ghouston@actrix.gen.nz>
 857
 858         * error.c (scm_error): new procedure.
 859
 860         * error.h: prototype for scm_error.
 861
 862         * Makefile.in (install): install scmconfig.h from the current
 863         directory, not $(srcdir).

 875         tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
 876         vports.h, weaks.h: #include "libguile/__scm.h", not
 877         <libguile/__scm.h>.  This allows 'gcc -MM' to determine which
 878         dependencies are within libguile properly.
 879
 880 Thu Sep  5 11:38:07 1996  Jim Blandy  <jimb@floss.cyclic.com>
 881
 882         * Makefile.in (.c.x): Simplify; there's no need to run this rule
 883         when scmconfig.h doesn't exist.
 884
 885         * load.c (scm_sys_try_load): Correct spelling.
 886
 887         * feature.c (scm_loc_features): Make this static.
 888
 889         * Makefile.in (libpath.h): Omit trailing slash from path.  We
 890         shouldn't require it of users, so why put it here?
 891
 892         Move code to initialize and search %load-path from ice-9 to C
 893         code, so we can use the load-path to find the ice-9 boot code;
 894         this makes it easier to run Guile without installing it.  See
 895         corresponding changes in guile/Makefile.in.
 896         * feature.c: Move stuff concerned with the load path to load.c.
 897         (scm_compiled_library_path): Deleted.
 898         Don't #include libpath.h here.
 899         * feature.h: Don't mention scm_compiled_library_path.
 900         * load.c: #include "libpath.h" here, as well as <sys/types.h>,
 901         <sys/stat.h>, and <unistd.h> (if present).
 902         (R_OK): #define if the system hasn't deigned to.
 903         (scm_loc_load_path): New variable.
 904         (scm_init_load_path, scm_sys_search_load_path,
 905         scm_sys_try_load_path): New functions.
 906         (scm_init_load): Initialize scm_loc_load_path to point to the
 907         value cell of the Scheme %load-path variable.
 908         * load.h: Add declarations for scm_sys_search_load_path,
 909         scm_sys_try_load_path.
 910         * init.c: Call scm_init_load_path.
 911         * Makefile.in (feature.o, load.o): Dependencies updated.
 912
 913         * load.c, load.h: Rewrite using PROTO macro.

 915 Thu Sep  5 01:54:33 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 916
 917         * gc.c (scm_cellp): New function: C predicate to determine if an
 918         SCM value can be regarded as a pointer to a cell on the heap.
 919
 920         * gc.h: Added declaration of scm_cellp.
 921
 922         * gdb_interface.h: New file: The GDB interface header from the GDB
 923         distribution.
 924
 925         * gdbint.c: New file: GDB interface.
 926
 927         * gdbint.h: New file: GDB interface.
 928
 929         * libguile.h: Added #include <libguile/gdbint.h>.
 930
 931         * init.c (scm_boot_guile): Added scm_init_gdbint.
 932
 933         * Makefile.in: Added gdb_interface.h, gdbint.[hc].
 934         Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
 935         found if object files and source are kept separate).

 937 Wed Sep  4 14:35:02 1996  Jim Blandy  <jimb@floss.cyclic.com>
 938
 939         * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
 940
 941 Wed Sep  4 01:30:47 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 942
 943         * configure.in: Don't substitute the values of TCL_SRC_DIR and
 944         TK_SRC_DIR; they're not relevant any more.
 945
 946         * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
 947         * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
 948
 949 Wed Sep  4 00:55:49 1996  Jim Blandy  <jimb@floss.cyclic.com>
 950
 951         * PLUGIN/guile.config (xtra_cflags): Include .. in the header
 952         search path, so we can find the <libguile/MUMBLE.h> headers.
 953
 954         * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
 955
 956         * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
 957         implicit in the .c.o rule.
 958         (.c.x): Don't mention ALL_CFLAGS here; its value is included in
 959         $(CC) already.
 960
 961         Put the library path in a header file, instead of passing it on
 962         the command line in every compilation.
 963         * Makefile.in (libpath.h): New target.
 964         (feature.o): Depend on libpath.h.
 965         (clean): Delete libpath.h.
 966         (ALL_CFLAGS): Don't use -DLIBRARY_PATH here.  Instead ...
 967         * feature.c: ... #include "libpath.h" here.
 968         * .cvsignore: Ignore libpath.h.
 969
 970 *       Don't install the unwashed masses of Guile header files in the
 971         main #include path; put most of them in a subdirectory called
 972         'libguile'.  This avoids naming conflicts between Guile header
 973         files and system header files (of which there were a few).
 974         * Makefile.in (pkgincludedir): Deleted.
 975         (innerincludedir): New variable; this and $(includedir) are enough.
 976         (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
 977         (installed_h_files): Divide this up.  Now this variable lists
 978         those header files which should go into $(includedir) (i.e. appear
 979         directly in the #include path), and ...
 980         (inner_h_files): ... this new variable says which files appear in
 981         a subdirectory, and are referred to as <libguile/mumble.h>.
 982         (h_files): List them both.
 983         (install): Create innerincludedir, not pkgincludedir.  Put
 984         the installed_h_files and inner_h_files in their proper places.
 985         (uninstall): Corresponding changes.
 986         * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
 987         continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,

 994         tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
 995         vports.h, weaks.h: Find __scm.h in its new location.
 996         * __scm.h: Find scmconfig.h and tags.h in their new locations
 997         (they're both "inner" files).
 998
 999 Tue Sep  3 20:27:35 1996  Jim Blandy  <jimb@floss.cyclic.com>
1000
1001         * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
1002
1003 Tue Sep  3 19:53:00 1996  Jim Blandy  <jimb@totoro.cyclic.com>
1004
1005         * posix.c: Doc fixes.
1006
1007 Mon Sep  2 15:22:40 1996  Jim Blandy  <jimb@totoro.cyclic.com>
1008
1009         * socket.c: Don't include a prototype for inet_aton; just use a
1010         K&R style declaration, to avoid warnings but minimize the chance
1011         of conflicts with the system.
1012
1013         On NextStep, <utime.h> doesn't define struct utime, unless we
1014         #define _POSIX_SOURCE before #including it.
1015         * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
1016         * acconfig.h: New comment text for above CPP symbol.
1017         * configure.in: Call it.
1018         * posix.c: #define _POSIX_SOURCE if it seems necessary.
1019
1020         * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
1021         in the list.
1022         * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
1023         testing for __EMX__.
1024
1025         * posix.c: #include <libc.h>, if it exists.
1026
1027         * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
1028         don't even know if the latter exists.
1029
1030         * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
1031         s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
1032         s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
1033
1034         * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
1035         header files don't.
1036         (scm_init_posix): Use them when initializing the Scheme constants
1037         of the same name.
1038
1039 Fri Aug 30 16:01:30 1996  Jim Blandy  <jimb@floss.cyclic.com>
1040
1041         * Makefile.in (libdir, includedir, bindir): Use the
1042         autoconf-supplied values, instead of deriving them ourselves.
1043         (pkgincludedir, datadir, pkgdatadir): New variables.
1044         (install, uninstall): Put the header files in a special
1045         subdirectory, not in the main search path.
1046
1047         * Makefile.in (ALL_CFLAGS): Provide the proper value for
1048         LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
1049
1050         * Makefile.in (IMPLPATH): Deleted; never used.
1051
1052         * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
1053         on the Tcl/Tk source any more.
1054         (INCLUDE_CFLAGS): Remove references to the above.
1055
1056         * Makefile.in (version.o): Corrected dependencies.
1057
1058 Thu Aug 29 23:06:19 1996  Thomas Morgan  <tmorgan@gnu.ai.mit.edu>
1059
1060         * libguile.h: #include "version.h"
1061
1062         * init.c (scm_boot_guile): Call scm_init_version.
1063         * gscm.c (gscm_run_scm): Call scm_init_version.
1064
1065         * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
1066         GUILE_VERSION): AC_DEFINE these.
1067         (acconfig.h): #undef the above symbols.
1068
1069         * Makefile.in (libobjs): Add version.o.
1070         (installed_h_files): Add version.h.
1071         (c_files): Add version.c.
1072         (gen_c_files): Add version.x.
1073         (version.o): New rule.
1074         (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
1075         chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
1076         fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
1077         genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
1078         mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
1079         objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
1080         procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
1081         simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
1082         strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
1083         throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
1084         weaks.o): Add version.h to dependency lists.
1085         (markers.o): Remove duplicate rule.
1086
1087         * version.h: New file.
1088
1089         * version.c: New file.
1090
1091 Thu Aug 29 15:21:39 1996  Jim Blandy  <jimb@totoro.cyclic.com>
1092
1093         * symbols.c (scm_strhash): scm_downcase is now a function, not an
1094         array; use it appropriately.  Since GCC is quite happy to
1095         subscript functions, it never warned us about this; we should use
1096         -Wpointer-arith in the future.  I guess we never tested
1097         case-insensitivity.
1098
1099 Wed Aug 28 18:52:22 1996  Jim Blandy  <jimb@totoro.cyclic.com>
1100
1101         * socket.c: Doc and copyright fixes.
1102
1103 Sat Aug 24 05:29:19 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
1104
1105         * debug.c: Fixed and improved gdb support.
1106
1107 Fri Aug 23 18:00:16 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
1108
1109         * socket.c: Added declaration of inet_aton to avoid compiler
1110         warning.  (Hope this solution is correct.)
1111
1112         * stime.c: Added declaration of ftime.  (This is missing in
1113         Solaris 2 headers.)
1114
1115 Fri Aug 23 02:03:32 1996  Gary Houston  <ghouston@actrix.gen.nz>
1116
1117         * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
1118
1119         * Makefile.in (c_files): add strerror.c.
1120
1121         * strerror.c: new file from Emacs' sysdep.c.
1122         maybe configure should also check for sys_errlist.
1123
1124         * configure.in (AC_REPLACE_FUNCS): add strerror.
1125
1126 Fri Aug 23 03:02:46 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
1127
1128         * debug.c (scm_init_debug): Added initialization for
1129         scm_evaluator_traps.
1130
1131         * debug.h, debug.c: Various name changes.
1132         (Mostly prefixing with SCM_.)  Renamed "debug-options" -->
1133         "debug-options-interface".  See commentary in options.c.
1134
1135         * options.h, options.c: Options now have documentation strings.
1136         Also added a long explanatory commentary.
1137
1138         * eval.c, print.h, print.c, read.h, read.c: Modifications to
1139         run-time options.
1140
1141         * gscm.c, init.c, root.c, throw.c: Bug fixes:
1142         last_debug_info_frame is now updated in all cases.
1143
1144         * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
1145         checking.
1146
1147 Thu Aug 22 17:34:17 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
1148
1149         * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
1150         Added option STACK_CHECKING.
1151
1152 Tue Aug 20 18:48:40 1996  Mikael Djurfeldt  <djurfeldt@nada.kth.se>
1153
1154         * Makefile.in: Added {debug,options,srcprop}.{h,c}
1155
1156         * __scm.h: Removed symbols for debugging support.
1157
1158         * acconfig.h: Added symbols for debugging support.
1159
1160 *       * configure.in: Added user option for debugging support.
1161         --enable-debug will include the debugging code into libguile.a.
1162
1163         * continuations.c (scm_make_cont): Enlarged the #if 0 around
1164         scm_relocate_chunk_to_heap.
1165
1166 *       * debug.c: New file: low-level debugging support.  It also
1167         includes support for debugging with gdb.  (The extensions to gdb
1168         are written by Per Bothner at Cygnus.)
1169
1170         * debug.h: New file: low-level debugging support.
1171
1172 *       * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
1173         argument pairs.  Extensive modifications to the debugging
1174         evaluator.  Added "SECTION:" commentaries to clarify what happens
1175         when, during double compilation.  Renamed EVALIMP --> EVALIM.
1176         Renamed EVAL --> XEVAL.  Removed function evalcar.  Defined
1177         evalcar to scm_eval_car.  Added explanation of "EVAL" symbols to
1178         the beginning of the file.  New procedure: scm_unmemocopy.
1179         Added some global state variables needed by the debugging
1180         evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
1181         check_entry, check_apply, check_exit, debug_options and
1182         evaluator_traps.  New acro: undefine.
1183
1184         * eval.h: Renamed EVAL --> XEVAL.
1185
1186         * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
1187         --> scm_make_weak_key_hash_table.
1188
1189         * init.c (scm_restart_stack, scm_boot_guile): Added initialization
1190         of SCM_DFRAME.  Added calls to scm_init_{debug,options,srcprop}.
1191
1192         * libguile.h: Conditionally include debug.h
1193
1194 *       * objprop.c (scm_object_properties, scm_set_object_properties_x):
1195         scm_object_properties shouldn't return handle.  `handle' now gets
1196         initialized in scm_set_object_properties_x.  scm_object_properties
1197         doesn't any longer create an entry in scm_object_whash.
1198
1199 *       * options.c: New file: handling of run time options.
1200
1201         * options.h: New file: handling of run time options.
1202
1203         * posix.c (scm_getpgrp): Cast pointer to getpgrp.
1204
1205 *       * print.c: New procedure: scm_print_options
1206
1207         * print.h: Defines for print options.
1208
1209 *       * read.c: New procedure: scm_read_options
1210
1211         * read.h: Defines for reader options.
1212
1213         * root.h: Added scm_source_whash among scm_sys_protects.
1214
1215 *       * srcprop.c: New file: source properties.
1216
1217         * srcprop.h: New file: source properties.
1218
1219         * throw.c (jbsmob): Jump buffers are now correctly allocated.
1220         (Bug found by A. Green.)
1221
1222 *       * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
1223
1224         * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
1225
1226 Thu Aug 15 02:05:14 1996  Jim Blandy  <jimb@totoro.cyclic.com>
1227
1228         * libguile.h: #include "objprop.h"; I guess this was forgotten.
1229
1230         * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
1231         and should be called by the final client.
1232
1233 Wed Aug 14 21:41:37 1996  Jim Blandy  <jimb@totoro.cyclic.com>
1234
1235         * gc.h: Use the PROTO macro when declaring functions.
1236         * gc.c: Use the PROTO macro when declaring static functions.
1237         Remove the CPP hair around function definitions.
1238
1239         * gc.c (scm_init_storage): Initialize scm_asyncs.
1240
1241         * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
1242         preprocessor symbol; "__scm.h" is where it might get #defined.
1243         * __scm.h: Similar: #include <scmconfig.h> before testing
1244         HAVE_LIMITS_H.
1245
1246         * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
1247
1248 Fri Aug  9 11:09:28 1996  Jim Blandy  <jimb@totoro.cyclic.com>
1249
1250 *       * init.c (scm_boot_guile): Add init_func argument; call
1251         (*init_func) instead of calling scm_appinit; it's ucky to
1252         hard-code names for the user's procedures.
1253         * init.h (scm_boot_guile): Adjust declaration.
1254
1255         * __scm.h (PROTO): New macro, for declaring functions with
1256         prototypes.
1257
1258         * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
1259         eliminate all the __STDC__ conditionals.
1260         (scm_boot_guile): Add declaration.
1261         * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
1262         Remove __STDC__ conditionals around function definitions; the
1263         declarations in init.h will provide the same information, more
1264         usefully.
1265
1266         * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
1267         complain about it in the error message; the error message is
1268         adequate without that note, and there's nothing the user can do
1269         about it.
1270
1271 Wed Aug  7 14:14:46 1996  Jim Blandy  <jimb@totoro.cyclic.com>
1272
1273         * Makefile.in (ancillary): Drop def.sed.
1274
1275         * posix.c (scm_init_posix): Use numeric values, rather than
1276         CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
1277         F_OK.  The symbols aren't available on some systems, and I'm
1278         pretty sure their values are fixed by common widespread practice.
1279         * ioext.c (scm_init_ioext): Code here defined them too; remove it.
1280
1281         More functions unavailable on some systems.
1282         * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
1283         tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
1284         check for.
1285         * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
1286         * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
1287         scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
1288         bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
1289         stub that signals an error as the #else.
1290
1291         * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
1292
1293 Wed Aug  7 06:28:42 1996  Gary Houston  <ghouston@actrix.gen.nz>
1294
1295         * Fixes motivated by Petr Adamek <adamek@mit.edu>:
1296
1297         * unif.c: include ramap.h.
1298
1299         * read.c (endif): case_insensative_p renamed case_insensitive_p.
1300
1301         * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
1302
1303         * ports.c: include sys/ioctl.h.
1304
1305         * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
1306
1307         * configure.in: check for sys/ioctl.h.
1308
1309         * ports.c: include <malloc.h> not "malloc.h".
1310
1311         * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
1312
1313         * fports.c: remove ttyname and tmpnam declarations.
1314
1315         * posix.c: fewer ttyname declarations.
1316
1317         * fports.c: include <string.h> not "string.h".
1318
1319         * init.c, ioext.c: include string.h and unistd.h.
1320
1321         * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
1322
1323         * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
1324         genio.c, simpos.c, vports.c: include string.h.

1344
1345         Changes for NeXT, suggested by Robert Brown.
1346         * configure.in: Call AC_TYPE_MODE_T.
1347         (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
1348         NeXT.  Put header file list in alphabetical order.
1349         * configure, scmconfig.h.in: Regenerated.
1350         * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
1351
1352         * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
1353         for strerror.
1354
1355         * acconfig.h: New file, providing documentation for the CPP
1356         symbols defined in configure.in

1358
1359 Sat Aug  3 01:27:14 1996  Gary Houston  <ghouston@actrix.gen.nz>
1360
1361         * ioext.c (scm_sys_fdopen): fix the port-table assignment.
1362
1363 *       * fports.c (scm_open_file): don't return #f, throw error.
1364
1365 *       * ioext.c (fileno): renamed from %fileno.
1366         (soft-fileno): deleted.
1367
1368         * ports.c (scm_port_revealed): don't need to check for -1 from
1369         scm_revealed_count.

1371

1375
1376         * scmconfig.h.in: add HAVE_STRUCT_LINGER.
1377
1378         * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
1379
1380 Thu Aug  1 02:58:39 1996  Jim Blandy  <jimb@totoro.cyclic.com>
1381
1382         * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
1383         This is necessary on Ultrix, and doesn't hurt portability.
1384
1385         * Makefile.in (dist-dir): New target, implementing a new dist system.
1386         (installed_h_files): Put in alphabetical order.

1388         (c_files): Remove duplicate entries for markers.c.
1389         (ancillary): Renamed from anillery; all uses changed.  Remove
1390         PLUGIN; it's a directory, and needs special treatment in dist-dir.
1391         Remove all the ../doc/* files; doc/Makefile.in handles that.
1392
1393         * Makefile.in (libobjs): Remove duplicate entry for markers.o.
1394
1395         * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
1396         every if must have an else, or else the whole command has a
1397         non-zero exit code whenever the if's condition is false.
1398
1399 Thu Aug  1 08:22:24 1996  Gary Houston  <ghouston@actrix.gen.nz>

1404
1405 *       * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
1406         have been once.
1407
1408 *       * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
1409         Remove leading % from scheme names.
1410         Do not return error values, call SCM_SYSERROR or similar.
1411
1412         * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
1413
1414 Wed Jun 12 00:28:31 1996  Tom Lord  <lord@beehive>

1421         (scm_list_head): added list-head for rapidly chopping argument
1422         lists off of longer lists (and similar).
1423
1424 Tue Jun  4 09:40:33 1996  Tom Lord  <lord@beehive>
1425
1426         * objprop.c (scm_object_property): assq the cdr of the whash
1427         handle for obj, not the handle itself.

1430
1431         * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
1432         weak hash tables last of all marking to avoid an obscure gc bug.
1433         WARNING: circular lists stored in a weak hash table will hose us.
1434
1435 Fri May 24 09:53:39 1996  Tom Lord  <lord@beehive>
1436

1441 Wed May 22 20:07:01 1996  Tom Lord  <lord@beehive>
1442
1443         * init.c (scm_boot_guile): prevent gc with scm_block_gc not
1444         scm_gc_heap_lock!
1445
1446 Wed May 15 16:13:29 1996  Tom Lord  <lord@beehive>
1447
1448         * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.

1462
1463         * ports.c (scm_ports_prehistory): size malloced here doesn't
1464         matter so long as it is non-0 (got rid of "* 4").
1465
1466 Tue May  7 11:43:37 1996  Tom Lord  <lord@beehive>
1467
1468         * gscm.h: gscm_mkarray eliminated (presumably was not being used
1469         since its definition was bogus).
1470
1471 Mon May  6 13:02:56 1996  Tom Lord  <lord@beehive>
1472
1473         * mallocs.[ch]: back again (for rx at least).
1474
1475 Wed Apr 17 08:54:20 1996  Tom Lord  <lord@beehive>
1476
1477         * ports.c: removed functions relating to the mapping between ports
1478         and descriptors.   (That stuff is unix-specific and should be collected
1479         in a separate library).
1480
1481         * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
1482         (Tom Mckay@avanticorp.com)

1485
1486         * gc.c (scm_gc_sweep): Immediates in weak vectors were not
1487         handled correctly (SCM_FREEP was applied to them) -- test for
1488         NIMP.  Keys in weak hash tables were spuriously (though harmlessly)
1489         being overwritten with #f.   (brown@grettir.bibliotech.com)
1490
1491 Tue Apr  2 22:25:00 1996  Tom Lord  <lord@beehive>
1492

1508         Generalized assoc and hash-table functions.
1509         Factored pairs.c into multiple files.

1518         NOTE: fgetc may not be interruptable.
1519
1520         * procprop.c (scm_stand_in_scm_proc):
1521         NOTE: don't use a alist here.

1527         after freeing part of the port table.
1528
1529 Thu Feb 29 16:21:17 1996  Tom Lord  <lord@beehive>
1530
1531         * strports.c (scm_mkstrport):
1532         * vports.c (scm_make_soft_port): allocate a port table entry
1533         (possibly triggering gc) before setting the tag of the corresponding
1534         ports handle.
1535
1536         * pairs.c (scm_delq_x): never throw an error.
1537
1538         * vectors.c (scm_make_vector): made the default vector fill argument
1539         into '() (much more useful than the previous value, "#unspecified")
1540
1541 Mon Feb 26 17:19:09 1996  Tom Lord  <lord@beehive>
1542
1543         * ports.c (scm_add_to_port_table): Added fields
1544         to port table entries: file_name, line_num, col.
1545         Update these in open_file, gen_getc and gen_ungetc.
1546         Added procedures to access those fields.
1547
1548 Sun Feb 25 00:10:36 1996  Tom Lord  <lord@beehive>

1563
1564         * gc.c (scm_gc_end): simulate a signal at the end of each GC.
1565         (scm_gc_stats): return an assoc of useful data.  Replaces "room"
1566         and the stats reporting formerlly built into repl.
1567
1568         * repl.[ch]: removed.
1569         GC statistics keeping moved to gc.c.
1570         Other statistics keeping can be done from Scheme.

1575         * cnsvobj.c (gscm_is_gscm_obj): new file for old functions (icky
1576         conservatively marked objects).
1577
1578         * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
1579
1580         * error.c (scm_init_error): init system_error_sym here, not in repl.c.
1581
1582         * feature.c (scm_compiled_library_path): moved here from repl.c.
1583         This file is for stuff relating specifically to Scheme libraries
1584         like slib.
1585
1586         * eval.c (scm_m_define): don't give warning about redefinition, don't
1587         check verbosity.
1588
1589         NOTE: this should throw a resumable exception with parameters --
1590         the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
1591
1592         * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
1593
1594         * error.c: scm_warn eliminated.

1600
1601         * gscm.c: got rid of verbosity functions.
1602

1606         between the call to procedurep and use.
1607
1608         * error.c (scm_everr):
1609         * gc.c (fixconfig):
1610         * gsubr.c (scm_make_gsubr): use exit, not scm_quit.  still wrong,
1611         but less so.
1612
1613         * strports.c: don't reveal the port's string to the caller
1614         because it changes size.
1615
1616         (stputc stwrite): check/change the strings length with interrupts
1617         blocked.
1618
1619         * objprop.c (scm_set_object_property_x &c): use the generic
1620         hashing functions and be threadsafe.

1623         (per suggestion jaffer@gnu.ai.mit.edu).
1624
1625         * mbstrings.c (scm_multi_byte_string): guard against argument list
1626         changing length.
1627
1628         * strings.c (scm_make_string): loop cleanup
1629
1630         * unif.c (scm_vector_set_length_x): scm_vector_set_length_x no longer
1631         a scheme function.
1632
1633         * weaks.c (scm_weak_vector): guard against argument list
1634         changing length.
1635
1636         * variable.c (scm_builtin_variable): check for/make a built-in
1637         variable automicly.
1638
1639         * vectors.c (scm_vector): while filling the new array,
1640         guard against a list of fill elements that grows after
1641         the vector is allocated.
1642
1643         * hashtab.c -- new file: general hash table
1644         functions.  hash, hashq, hashv, hashx.
1645
1646         * tags.h: made wvect an option bit of vector.
1647
1648 Mon Feb 19 09:38:05 1996  Tom Lord  <lord@beehive>
1649
1650         * symbols.c: made the basic symbol table operations atomic.
1651
1652         * root.c &c.: collected stack-specific global state.
1653         linum/colnum etc *should* be port-specific state.
1654
1655         * struct.c (scm_init_struct): init the first struct type during
1656         initialization to fix a race condition.
1657
1658         * continuations.c (scm_dynthrow): pass throwval in the 'regs'
1659         object, not in a global.
1660         (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
1661
1662         * throw.c (_scm_throw): Pass throwval on the stack, not in a global
1663         (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)

1666         and C symbols to begin with SCM_ or scm_.
1667
1668 Sun Feb 18 15:55:38 1996  Tom Lord  <lord@beehive>
1669
1670         * gsubr.c (scm_gsubr_apply): statically allocate the
1671         array of arguments (bothner@cygnus.com).
1672
1673 Sat Feb 17 20:20:40 1996  Tom Lord  <lord@beehive>
1674
1675         * scmsigs.c: Simplified to use async rountines.
1676
1677         * async.c: New support for interrupt handlers.
1678
1679 Thu Feb 15 11:39:09 1996  Tom Lord  <lord@beehive>
1680
1681         * symbols.c (scm_string_to_symbol et al.): number of tweaky changes to
1682         set the multi_byte flag correctly in symbols.  This is wrong.
1683         intern_obbary_soft and msymbolize should take an extra parameter.
1684         Also, weird multibyte symbols don't print correctly.
1685         The weird symbol syntax is also a bit bogus (emacs doesn't quite
