   1 Fri Aug 23 03:02:46 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
   2
   3         * debug.h, debug.c: Various name changes.
   4         (Mostly prefixing with SCM_.)  Renamed "debug-options" -->
   5         "debug-options-interface".  See commentary in options.c.
   6
   7         * options.h, options.c: Options now have documentation strings.
   8         Also added a long explanatory commentary.
   9
  10         * eval.c, print.h, print.c, read.h, read.c: Modifications to
  11         run-time options.
  12
  13         * gscm.c, init.c, root.c, throw.c: Bug fixes:
  14         last_debug_info_frame is now updated in all cases.
  15
  16         * stackchk.h, stackchk.c: Guile now performs stack checking.
  17
  18 Thu Aug 22 17:34:17 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
  19
  20         * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
  21         Added option STACK_CHECKING.
  22
  23 Tue Aug 20 18:48:40 1996  Mikael Djurfeldt  <djurfeldt@nada.kth.se>
  24
  25         * Makefile.in: Added {debug,options,srcprop}.{h,c}
  26
  27         * __scm.h: Removed symbols for debugging support.
  28
  29         * acconfig.h: Added symbols for debugging support.
  30
  31 *       * configure.in: Added user option for debugging support.
  32         --enable-debug will include the debugging code into libguile.a.
  33
  34         * continuations.c (scm_make_cont): Enlarged the #if 0 around
  35         scm_relocate_chunk_to_heap.
  36
  37 *       * debug.c: New file: low-level debugging support.  It also
  38         includes support for debugging with gdb.  (The extensions to gdb
  39         are written by Per Bothner at Cygnus.)
  40
  41         * debug.h: New file: low-level debugging support.
  42
  43 *       * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
  44         argument pairs.  Extensive modifications to the debugging
  45         evaluator.  Added "SECTION:" commentaries to clarify what happens
  46         when, during double compilation.  Renamed EVALIMP --> EVALIM.
  47         Renamed EVAL --> XEVAL.  Removed function evalcar.  Defined
  48         evalcar to scm_eval_car.  Added explanation of "EVAL" symbols to
  49         the beginning of the file.  New procedure: scm_unmemocopy.
  50         Added some global state variables needed by the debugging
  51         evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
  52         check_entry, check_apply, check_exit, debug_options and
  53         evaluator_traps.  New acro: undefine.
  54
  55         * eval.h: Renamed EVAL --> XEVAL.
  56
  57         * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
  58         --> scm_make_weak_key_hash_table.
  59
  60         * init.c (scm_restart_stack, scm_boot_guile): Added initialization
  61         of SCM_DFRAME.  Added calls to scm_init_{debug,options,srcprop}.
  62
  63         * libguile.h: Conditionally include debug.h
  64
  65 *       * objprop.c (scm_object_properties, scm_set_object_properties_x):
  66         scm_object_properties shouldn't return handle.  `handle' now gets
  67         initialized in scm_set_object_properties_x.  scm_object_properties
  68         doesn't any longer create an entry in scm_object_whash.
  69
  70 *       * options.c: New file: handling of run time options.
  71
  72         * options.h: New file: handling of run time options.
  73
  74         * posix.c (scm_getpgrp): Cast pointer to getpgrp.
  75
  76 *       * print.c: New procedure: scm_print_options
  77
  78         * print.h: Defines for print options.
  79
  80 *       * read.c: New procedure: scm_read_options
  81
  82         * read.h: Defines for reader options.
  83
  84         * root.h: Added scm_source_whash among scm_sys_protects.
  85
  86 *       * srcprop.c: New file: source properties.
  87
  88         * srcprop.h: New file: source properties.
  89
  90         * throw.c (jbsmob): Jump buffers are now correctly allocated.
  91         (Bug found by A. Green.)
  92
  93 *       * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
  94
  95         * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
  96
  97 Thu Aug 15 02:05:14 1996  Jim Blandy  <jimb@totoro.cyclic.com>
  98
  99         * libguile.h: #include "objprop.h"; I guess this was forgotten.
 100
 101         * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
 102         and should be called by the final client.
 103
 104 Wed Aug 14 21:41:37 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 105
 106         * gc.h: Use the PROTO macro when declaring functions.
 107         * gc.c: Use the PROTO macro when declaring static functions.
 108         Remove the CPP hair around function definitions.
 109
 110         * gc.c (scm_init_storage): Initialize scm_asyncs.
 111
 112         * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
 113         preprocessor symbol; "__scm.h" is where it might get #defined.
 114         * __scm.h: Similar: #include <scmconfig.h> before testing
 115         HAVE_LIMITS_H.
 116
 117         * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
 118
 119 Fri Aug  9 11:09:28 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 120
 121 *       * init.c (scm_boot_guile): Add init_func argument; call
 122         (*init_func) instead of calling scm_appinit; it's ucky to
 123         hard-code names for the user's procedures.
 124         * init.h (scm_boot_guile): Adjust declaration.
 125
 126         * __scm.h (PROTO): New macro, for declaring functions with
 127         prototypes.
 128
 129         * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
 130         eliminate all the __STDC__ conditionals.
 131         (scm_boot_guile): Add declaration.
 132         * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
 133         Remove __STDC__ conditionals around function definitions; the
 134         declarations in init.h will provide the same information, more
 135         usefully.
 136
 137         * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
 138         complain about it in the error message; the error message is
 139         adequate without that note, and there's nothing the user can do
 140         about it.
 141
 142 Wed Aug  7 14:14:46 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 143
 144         * Makefile.in (ancillary): Drop def.sed.
 145
 146         * posix.c (scm_init_posix): Use numeric values, rather than
 147         CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
 148         F_OK.  The symbols aren't available on some systems, and I'm
 149         pretty sure their values are fixed by common widespread practice.
 150         * ioext.c (scm_init_ioext): Code here defined them too; remove it.
 151
 152         More functions unavailable on some systems.
 153         * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
 154         tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
 155         check for.
 156         * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
 157         * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
 158         scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
 159         bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
 160         stub that signals an error as the #else.
 161
 162         * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
 163
 164 Wed Aug  7 06:28:42 1996  Gary Houston  <ghouston@actrix.gen.nz>
 165
 166         * Fixes motivated by Petr Adamek <adamek@mit.edu>:
 167
 168         * unif.c: include ramap.h.
 169
 170         * read.c (endif): case_insensative_p renamed case_insensitive_p.
 171
 172         * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
 173
 174         * ports.c: include sys/ioctl.h.
 175
 176         * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
 177
 178         * configure.in: check for sys/ioctl.h.
 179
 180         * ports.c: include <malloc.h> not "malloc.h".
 181
 182         * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
 183
 184         * fports.c: remove ttyname and tmpnam declarations.
 185
 186         * posix.c: fewer ttyname declarations.
 187
 188         * fports.c: include <string.h> not "string.h".
 189
 190         * init.c, ioext.c: include string.h and unistd.h.
 191
 192         * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
 193
 194         * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
 195         genio.c, simpos.c, vports.c: include string.h.
 196
 197         * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
 198
 199         * fdsocket.c (getsockopt, setsockopt): change type of optlen from
 200         scm_sizet to int.
 201         (scm_addr_buffer_size): change type from scm_sizet to int.
 202         (accept, getsockname, getpeername, recvfrom): change type of tmp_size
 203         from scm_sizet to int.
 204
 205         * error.c: include unistd.h.
 206
 207         * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
 208         defined.
 209
 210         * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
 211
 212         * __scm.hd, def.sed: deleted.
 213
 214 Tue Aug  6 14:49:08 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 215
 216         Changes for NeXT, suggested by Robert Brown.
 217         * configure.in: Call AC_TYPE_MODE_T.
 218         (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
 219         NeXT.  Put header file list in alphabetical order.
 220         * configure, scmconfig.h.in: Regenerated.
 221         * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
 222
 223         * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
 224         for strerror.
 225
 226         * acconfig.h: New file, providing documentation for the CPP
 227         symbols defined in configure.in
 228         * acconfig-1.5.h: Removed; superceded by the above.
 229
 230 Sat Aug  3 01:27:14 1996  Gary Houston  <ghouston@actrix.gen.nz>
 231
 232         * ioext.c (scm_sys_fdopen): fix the port-table assignment.
 233
 234 *       * fports.c (scm_open_file): don't return #f, throw error.
 235
 236 *       * ioext.c (fileno): renamed from %fileno.
 237         (soft-fileno): deleted.
 238
 239         * ports.c (scm_port_revealed): don't need to check for -1 from
 240         scm_revealed_count.
 241         (scm_set_port_revealed_x): return unspecified, not #f.
 242
 243 *       * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
 244
 245         * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
 246
 247         * scmconfig.h.in: add HAVE_STRUCT_LINGER.
 248
 249         * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
 250
 251 Thu Aug  1 02:58:39 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 252
 253         * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
 254         This is necessary on Ultrix, and doesn't hurt portability.
 255
 256         * Makefile.in (dist-dir): New target, implementing a new dist system.
 257         (installed_h_files): Put in alphabetical order.
 258         Remove duplicate entries for markers.h and unif.h.
 259         (c_files): Remove duplicate entries for markers.c.
 260         (ancillary): Renamed from anillery; all uses changed.  Remove
 261         PLUGIN; it's a directory, and needs special treatment in dist-dir.
 262         Remove all the ../doc/* files; doc/Makefile.in handles that.
 263
 264         * Makefile.in (libobjs): Remove duplicate entry for markers.o.
 265
 266         * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
 267         every if must have an else, or else the whole command has a
 268         non-zero exit code whenever the if's condition is false.
 269
 270 Thu Aug  1 08:22:24 1996  Gary Houston  <ghouston@actrix.gen.nz>
 271
 272         * posix.c: include string.h.
 273
 274 Wed Jul 31 23:43:05 1996  Gary Houston  <ghouston@actrix.gen.nz>
 275
 276 *       * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
 277         have been once.
 278
 279 *       * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
 280         Remove leading % from scheme names.
 281         Do not return error values, call SCM_SYSERROR or similar.
 282
 283         * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
 284
 285 Wed Jun 12 00:28:31 1996  Tom Lord  <lord@beehive>
 286
 287         * struct.c (scm_init_struct): new file.
 288
 289 Fri Jun  7 14:02:00 1996  Tom Lord  <lord@beehive>
 290
 291         * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
 292         (scm_list_head): added list-head for rapidly chopping argument
 293         lists off of longer lists (and similar).
 294
 295 Tue Jun  4 09:40:33 1996  Tom Lord  <lord@beehive>
 296
 297         * objprop.c (scm_object_property): assq the cdr of the whash
 298         handle for obj, not the handle itself.
 299
 300 Mon Jun  3 17:19:30 1996  Tom Lord  <lord@beehive>
 301
 302         * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
 303         weak hash tables last of all marking to avoid an obscure gc bug.
 304         WARNING: circular lists stored in a weak hash table will hose us.
 305
 306 Fri May 24 09:53:39 1996  Tom Lord  <lord@beehive>
 307
 308         * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
 309         new functions similar to scm_substring_move_left_x and
 310         scm_substring_move_right_x.
 311
 312 Wed May 22 20:07:01 1996  Tom Lord  <lord@beehive>
 313
 314         * init.c (scm_boot_guile): prevent gc with scm_block_gc not
 315         scm_gc_heap_lock!
 316
 317 Wed May 15 16:13:29 1996  Tom Lord  <lord@beehive>
 318
 319         * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
 320
 321 Thu May  9 09:33:17 1996  Tom Lord  <lord@beehive>
 322
 323         * strports.c (scm_strprint_obj): convenience function.  C for
 324         (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
 325
 326         * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
 327                 removed to a separate library
 328
 329         * init.c (scm_boot_guile): copied from guile-tcl.c.
 330         Initialization specific to tcl interpreters removed.
 331
 332 Wed May  8 15:07:37 1996  Tom Lord  <lord@beehive>
 333
 334         * ports.c (scm_ports_prehistory): size malloced here doesn't
 335         matter so long as it is non-0 (got rid of "* 4").
 336
 337 Tue May  7 11:43:37 1996  Tom Lord  <lord@beehive>
 338
 339         * gscm.h: gscm_mkarray eliminated (presumably was not being used
 340         since its definition was bogus).
 341
 342 Mon May  6 13:02:56 1996  Tom Lord  <lord@beehive>
 343
 344         * mallocs.[ch]: back again (for rx at least).
 345
 346 Wed Apr 17 08:54:20 1996  Tom Lord  <lord@beehive>
 347
 348         * ports.c: removed functions relating to the mapping between ports
 349         and descriptors.   (That stuff is unix-specific and should be collected
 350         in a separate library).
 351
 352         * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
 353         (Tom Mckay@avanticorp.com)
 354
 355 Mon Apr 15 14:16:55 1996  Tom Lord  <lord@beehive>
 356
 357         * gc.c (scm_gc_sweep): Immediates in weak vectors were not
 358         handled correctly (SCM_FREEP was applied to them) -- test for
 359         NIMP.  Keys in weak hash tables were spuriously (though harmlessly)
 360         being overwritten with #f.   (brown@grettir.bibliotech.com)
 361
 362 Tue Apr  2 22:25:00 1996  Tom Lord  <lord@beehive>
 363
 364         * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs
 365         for a specific symbol or for all symbols.
 366
 367 Mon Apr  1 10:34:55 1996  Tom Lord  <lord@beehive>

 458         check verbosity.

 522
 523         * root.c &c.: collected stack-specific global state.

 526         * struct.c (scm_init_struct): init the first struct type during
 527         initialization to fix a race condition.

 552         * symbols.c (scm_string_to_symbol et al.): number of tweaky changes to
 553         set the multi_byte flag correctly in symbols.  This is wrong.
 554         intern_obbary_soft and msymbolize should take an extra parameter.
 555         Also, weird multibyte symbols don't print correctly.
 556         The weird symbol syntax is also a bit bogus (emacs doesn't quite
 557         cope).
