libguile/ChangeLog

   1 Tue Aug 20 18:48:40 1996  Mikael Djurfeldt  <djurfeldt@nada.kth.se>
   2
   3         * Makefile.in: Added {debug,options,srcprop}.{h,c}
   4
   5         * __scm.h: Removed symbols for debugging support.
   6
   7         * acconfig.h: Added symbols for debugging support.
   8
   9 *       * configure.in: Added user option for debugging support.
  10         --enable-debug will include the debugging code into libguile.a.
  11
  12         * continuations.c (scm_make_cont): Enlarged the #if 0 around
  13         scm_relocate_chunk_to_heap.
  14
  15 *       * debug.c: New file: low-level debugging support.  It also
  16         includes support for debugging with gdb.  (The extensions to gdb
  17         are written by Per Bothner at Cygnus.)
  18
  19         * debug.h: New file: low-level debugging support.
  20
  21 *       * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
  22         argument pairs.  Extensive modifications to the debugging
  23         evaluator.  Added "SECTION:" commentaries to clarify what happens
  24         when, during double compilation.  Renamed EVALIMP --> EVALIM.
  25         Renamed EVAL --> XEVAL.  Removed function evalcar.  Defined
  26         evalcar to scm_eval_car.  Added explanation of "EVAL" symbols to
  27         the beginning of the file.  New procedure: scm_unmemocopy.
  28         Added some global state variables needed by the debugging
  29         evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
  30         check_entry, check_apply, check_exit, debug_options and
  31         evaluator_traps.  New acro: undefine.
  32
  33         * eval.h: Renamed EVAL --> XEVAL.
  34
  35         * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
  36         --> scm_make_weak_key_hash_table.
  37
  38         * init.c (scm_restart_stack, scm_boot_guile): Added initialization
  39         of SCM_DFRAME.  Added calls to scm_init_{debug,options,srcprop}.
  40
  41         * libguile.h: Conditionally include debug.h
  42
  43 *       * objprop.c (scm_object_properties, scm_set_object_properties_x):
  44         scm_object_properties shouldn't return handle.  `handle' now gets
  45         initialized in scm_set_object_properties_x.  scm_object_properties
  46         doesn't any longer create an entry in scm_object_whash.
  47
  48 *       * options.c: New file: handling of run time options.
  49
  50         * options.h: New file: handling of run time options.
  51
  52         * posix.c (scm_getpgrp): Cast pointer to getpgrp.
  53
  54 *       * print.c: New procedure: scm_print_options
  55
  56         * print.h: Defines for print options.
  57
  58 *       * read.c: New procedure: scm_read_options
  59
  60         * read.h: Defines for reader options.
  61
  62         * root.h: Added scm_source_whash among scm_sys_protects.
  63
  64 *       * srcprop.c: New file: source properties.
  65
  66         * srcprop.h: New file: source properties.
  67
  68         * throw.c (jbsmob): Jump buffers are now correctly allocated.
  69         (Bug found by A. Green.)
  70
  71 *       * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
  72
  73         * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
  74
  75 Thu Aug 15 02:05:14 1996  Jim Blandy  <jimb@totoro.cyclic.com>
  76
  77         * libguile.h: #include "objprop.h"; I guess this was forgotten.
  78
  79         * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
  80         and should be called by the final client.
  81
  82 Wed Aug 14 21:41:37 1996  Jim Blandy  <jimb@totoro.cyclic.com>
  83
  84         * gc.h: Use the PROTO macro when declaring functions.
  85         * gc.c: Use the PROTO macro when declaring static functions.
  86         Remove the CPP hair around function definitions.
  87
  88         * gc.c (scm_init_storage): Initialize scm_asyncs.
  89
  90         * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
  91         preprocessor symbol; "__scm.h" is where it might get #defined.
  92         * __scm.h: Similar: #include <scmconfig.h> before testing
  93         HAVE_LIMITS_H.
  94
  95         * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
  96
  97 Fri Aug  9 11:09:28 1996  Jim Blandy  <jimb@totoro.cyclic.com>
  98
  99 *       * init.c (scm_boot_guile): Add init_func argument; call
 100         (*init_func) instead of calling scm_appinit; it's ucky to
 101         hard-code names for the user's procedures.
 102         * init.h (scm_boot_guile): Adjust declaration.
 103
 104         * __scm.h (PROTO): New macro, for declaring functions with
 105         prototypes.
 106
 107         * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
 108         eliminate all the __STDC__ conditionals.
 109         (scm_boot_guile): Add declaration.
 110         * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
 111         Remove __STDC__ conditionals around function definitions; the
 112         declarations in init.h will provide the same information, more
 113         usefully.
 114
 115         * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
 116         complain about it in the error message; the error message is
 117         adequate without that note, and there's nothing the user can do
 118         about it.
 119
 120 Wed Aug  7 14:14:46 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 121
 122         * Makefile.in (ancillary): Drop def.sed.
 123
 124         * posix.c (scm_init_posix): Use numeric values, rather than
 125         CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
 126         F_OK.  The symbols aren't available on some systems, and I'm
 127         pretty sure their values are fixed by common widespread practice.
 128         * ioext.c (scm_init_ioext): Code here defined them too; remove it.
 129
 130         More functions unavailable on some systems.
 131         * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
 132         tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
 133         check for.
 134         * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
 135         * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
 136         scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
 137         bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
 138         stub that signals an error as the #else.
 139
 140         * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
 141
 142 Wed Aug  7 06:28:42 1996  Gary Houston  <ghouston@actrix.gen.nz>
 143
 144         * Fixes motivated by Petr Adamek <adamek@mit.edu>:
 145
 146         * unif.c: include ramap.h.
 147
 148         * read.c (endif): case_insensative_p renamed case_insensitive_p.
 149
 150         * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
 151
 152         * ports.c: include sys/ioctl.h.
 153
 154         * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
 155
 156         * configure.in: check for sys/ioctl.h.
 157
 158         * ports.c: include <malloc.h> not "malloc.h".
 159
 160         * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
 161
 162         * fports.c: remove ttyname and tmpnam declarations.
 163
 164         * posix.c: fewer ttyname declarations.
 165
 166         * fports.c: include <string.h> not "string.h".
 167
 168         * init.c, ioext.c: include string.h and unistd.h.
 169
 170         * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
 171
 172         * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
 173         genio.c, simpos.c, vports.c: include string.h.
 174
 175         * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
 176
 177         * fdsocket.c (getsockopt, setsockopt): change type of optlen from
 178         scm_sizet to int.
 179         (scm_addr_buffer_size): change type from scm_sizet to int.
 180         (accept, getsockname, getpeername, recvfrom): change type of tmp_size
 181         from scm_sizet to int.
 182
 183         * error.c: include unistd.h.
 184
 185         * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
 186         defined.
 187
 188         * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
 189
 190         * __scm.hd, def.sed: deleted.
 191
 192 Tue Aug  6 14:49:08 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 193
 194         Changes for NeXT, suggested by Robert Brown.
 195         * configure.in: Call AC_TYPE_MODE_T.
 196         (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
 197         NeXT.  Put header file list in alphabetical order.
 198         * configure, scmconfig.h.in: Regenerated.
 199         * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
 200
 201         * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
 202         for strerror.
 203
 204         * acconfig.h: New file, providing documentation for the CPP
 205         symbols defined in configure.in
 206         * acconfig-1.5.h: Removed; superceded by the above.
 207
 208 Sat Aug  3 01:27:14 1996  Gary Houston  <ghouston@actrix.gen.nz>
 209
 210         * ioext.c (scm_sys_fdopen): fix the port-table assignment.
 211
 212 *       * fports.c (scm_open_file): don't return #f, throw error.
 213
 214 *       * ioext.c (fileno): renamed from %fileno.
 215         (soft-fileno): deleted.
 216
 217         * ports.c (scm_port_revealed): don't need to check for -1 from
 218         scm_revealed_count.
 219         (scm_set_port_revealed_x): return unspecified, not #f.
 220
 221 *       * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
 222
 223         * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
 224
 225         * scmconfig.h.in: add HAVE_STRUCT_LINGER.
 226
 227         * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
 228
 229 Thu Aug  1 02:58:39 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 230
 231         * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
 232         This is necessary on Ultrix, and doesn't hurt portability.
 233
 234         * Makefile.in (dist-dir): New target, implementing a new dist system.
 235         (installed_h_files): Put in alphabetical order.
 236         Remove duplicate entries for markers.h and unif.h.
 237         (c_files): Remove duplicate entries for markers.c.
 238         (ancillary): Renamed from anillery; all uses changed.  Remove
 239         PLUGIN; it's a directory, and needs special treatment in dist-dir.
 240         Remove all the ../doc/* files; doc/Makefile.in handles that.
 241
 242         * Makefile.in (libobjs): Remove duplicate entry for markers.o.
 243
 244         * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
 245         every if must have an else, or else the whole command has a
 246         non-zero exit code whenever the if's condition is false.
 247
 248 Thu Aug  1 08:22:24 1996  Gary Houston  <ghouston@actrix.gen.nz>
 249
 250         * posix.c: include string.h.
 251
 252 Wed Jul 31 23:43:05 1996  Gary Houston  <ghouston@actrix.gen.nz>
 253
 254 *       * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
 255         have been once.
 256
 257 *       * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
 258         Remove leading % from scheme names.
 259         Do not return error values, call SCM_SYSERROR or similar.
 260
 261         * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
 262
 263 Wed Jun 12 00:28:31 1996  Tom Lord  <lord@beehive>
 264
 265         * struct.c (scm_init_struct): new file.
 266
 267 Fri Jun  7 14:02:00 1996  Tom Lord  <lord@beehive>
 268
 269         * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
 270         (scm_list_head): added list-head for rapidly chopping argument
 271         lists off of longer lists (and similar).
 272
 273 Tue Jun  4 09:40:33 1996  Tom Lord  <lord@beehive>
 274
 275         * objprop.c (scm_object_property): assq the cdr of the whash
 276         handle for obj, not the handle itself.
 277
 278 Mon Jun  3 17:19:30 1996  Tom Lord  <lord@beehive>
 279
 280         * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
 281         weak hash tables last of all marking to avoid an obscure gc bug.
 282         WARNING: circular lists stored in a weak hash table will hose us.
 283
 284 Fri May 24 09:53:39 1996  Tom Lord  <lord@beehive>
 285
 286         * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
 287         new functions similar to scm_substring_move_left_x and
 288         scm_substring_move_right_x.
 289
 290 Wed May 22 20:07:01 1996  Tom Lord  <lord@beehive>
 291
 292         * init.c (scm_boot_guile): prevent gc with scm_block_gc not
 293         scm_gc_heap_lock!
 294
 295 Wed May 15 16:13:29 1996  Tom Lord  <lord@beehive>
 296
 297         * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
 298
 299 Thu May  9 09:33:17 1996  Tom Lord  <lord@beehive>
 300
 301         * strports.c (scm_strprint_obj): convenience function.  C for
 302         (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
 303
 304         * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
 305                 removed to a separate library
 306
 307         * init.c (scm_boot_guile): copied from guile-tcl.c.
 308         Initialization specific to tcl interpreters removed.
 309
 310 Wed May  8 15:07:37 1996  Tom Lord  <lord@beehive>
 311
 312         * ports.c (scm_ports_prehistory): size malloced here doesn't
 313         matter so long as it is non-0 (got rid of "* 4").
 314
 315 Tue May  7 11:43:37 1996  Tom Lord  <lord@beehive>
 316
 317         * gscm.h: gscm_mkarray eliminated (presumably was not being used
 318         since its definition was bogus).
 319
 320 Mon May  6 13:02:56 1996  Tom Lord  <lord@beehive>
 321
 322         * mallocs.[ch]: back again (for rx at least).
 323
 324 Wed Apr 17 08:54:20 1996  Tom Lord  <lord@beehive>
 325
 326         * ports.c: removed functions relating to the mapping between ports
 327         and descriptors.   (That stuff is unix-specific and should be collected
 328         in a separate library).
 329
 330         * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
 331         (Tom Mckay@avanticorp.com)
 332
 333 Mon Apr 15 14:16:55 1996  Tom Lord  <lord@beehive>
 334
 335         * gc.c (scm_gc_sweep): Immediates in weak vectors were not
 336         handled correctly (SCM_FREEP was applied to them) -- test for
 337         NIMP.  Keys in weak hash tables were spuriously (though harmlessly)
 338         being overwritten with #f.   (brown@grettir.bibliotech.com)
 339
 340 Tue Apr  2 22:25:00 1996  Tom Lord  <lord@beehive>
 341
 342         * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs
 343         for a specific symbol or for all symbols.
 344
 345 Mon Apr  1 10:34:55 1996  Tom Lord  <lord@beehive>
 346
 347         * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak
 348         keys and weak values confused).
 349
 350 Thu Mar 14 22:20:20 1996  Tom Lord  <lord@beehive>
 351
 352         * list.c (scm_last_pair): map '()=>'()
 353
 354 Wed Mar 13 16:43:34 1996  Tom Lord  <lord@beehive>
 355
 356         * pairs.c, hashtab.c, list.c, alist.c append.c, sequences.c:
 357         Generalized assoc and hash-table functions.
 358         Factored pairs.c into multiple files.
 359
 360 Fri Mar  8 14:44:39 1996  Tom Lord  <lord@beehive>
 361
 362         * gscm.c (gscm_run_scm): got rid of objprop.
 363
 364 Fri Mar  1 10:39:52 1996  Tom Lord  <lord@beehive>
 365
 366         * genio.c (scm_getc):
 367         NOTE: fgetc may not be interruptable.
 368
 369         * procprop.c (scm_stand_in_scm_proc):

 436         check verbosity.

 500
 501         * root.c &c.: collected stack-specific global state.

 505         initialization to fix a race condition.

 531         set the multi_byte flag correctly in symbols.  This is wrong.

 533         Also, weird multibyte symbols don't print correctly.
 534         The weird symbol syntax is also a bit bogus (emacs doesn't quite
 535         cope).

 753         know that it's safe to pass an object to gscm_get_type?)
 754         (gscm_get_type): Fix tyop in error message.
 755
 756         * variable.c (scm_variable_ref): fixed assertion test.
 757         (Robert STRANDH <strandh@labri.u-bordeaux.fr>)
 758
 759         * gscm.h: fixed several prototypes, notably gscm_vref.
 760         Add gscm_is_eq and temporarily commented out gscm_eq (see
 761         the note in gscm.h near gscm_eq if this change effects your
 762         code).

 764
 765         * pairs.c (scm_obj_length): see next entry.
 766
 767         * gscm.h (gscm_obj_length): A way to get an integer
 768         length for lists, strings, symbols (treated as strings),
 769         and vectors.  Returns -1 on error.
 770
 771         * eq.c (scm_equal_p): fixed smob case.
 772         (William Gribble <grib@arlut.utexas.edu>)
