libguile/ChangeLog

   1 Tue Oct  1 00:00:10 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
   2
   3         * feature.c (scm_init_feature): Added threads feature (needs to be
   4         initialized here, since features doesn't exist when
   5         scm_init_threads is called).
   6
   7         * libguile.h: Added #include "libguile/../threads/threads.h".
   8         (This is a kludge to get thread support working.  This should be
   9         fixed.)
  10
  11         * configure.in, acconfig.h: Added flags for thread support.
  12
  13         * scmsigs.c: Define `signal' to be `pthread_signal' if using
  14         mit-pthreads.
  15
  16         * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
  17         SCM_THREAD_CRITICAL_SECTION_END.  Moved marking of root data to
  18         root.c:mark_root.
  19
  20         * _scm.h: Added conditional #include "threads.h"
  21
  22         * __scm.h (SCM_ASYNC_TICK): Added call to macro
  23         SCM_THREADS_SWITCHING_CODE.
  24
  25         * init.c (scm_start_stack): Call `scm_make_root' to dynamically
  26         allocate the basic dynamic root object.
  27         (scm_boot_guile): Added call to scm_init_root.
  28
  29 *       * root.c, root.h: Added root smob.
  30         (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
  31         functions: Implements dynamic roots mostly according to spec in
  32         SCM manual.  Main difference is that the second argument is a
  33         throw handler rather than an error "thunk".
  34
  35         * root.h: Added declaration of scm_init_root.
  36
  37         * root.c: Added #include "genio.h", #include "smob.h", #include
  38         "pairs.h", #include "throw.h", #include "dynwind.h", #include
  39         "eval.h"
  40         (scm_init_root): Added #include "root.x".
  41
  42         * throw.c: Added #include "stackchk.h"
  43         (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
  44         SCM_ALLOW_INTS --> SCM_REALLOW_INTS.  This is so that scm_catch
  45         can be used in scm_call_with_new_root; Added reenabling of stack
  46         checking when catching a throw.
  47
  48 Sat Sep 28 02:07:43 1996  Gary Houston  <ghouston@actrix.gen.nz>
  49
  50         * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
  51         declare the char * to be const.  Avoids a warning in rgx.c.
  52
  53         * ports.h: spelling fix.
  54
  55         * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
  56         error messages.
  57
  58         * load.c (scm_sys_try_load_path): throw an error if file not found
  59         (like it says it in NEWS).
  60
  61 Tue Sep 24 06:48:38 1996  Gary Houston  <ghouston@actrix.gen.nz>
  62
  63         * load.c (scm_sys_try_load): don't check whether value returned
  64         by scm_open_file is #f, it won't be.  Always return SCM_UNSPECIFIED.
  65         Change the Scheme name from %try-load to primitive-load.
  66
  67         * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
  68         Can avoid passing a message, allowing it to be derived in the
  69         error handler (e.g., if we want to throw to the key both from
  70         Scheme and C).
  71
  72 Mon Sep 23 00:42:15 1996  Mikael Djurfeldt  <mdj@kenneth>
  73
  74 *       * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
  75         references now have a new appearance which is more compact and
  76         also gives a clue about what the target of the reference is.
  77         By setting parameters in the print state, more fancy printing can
  78         be achieved.  This is used by the (not yet commited) backtrace
  79         code.
  80
  81 Sun Sep 22 17:10:06 1996  Mikael Djurfeldt  <mdj@kenneth>
  82
  83         * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
  84         "print.h"
  85
  86         * print.c: Added #include "struct.h".  Removed function
  87         scm_prlist.
  88
  89         * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
  90         scm_iprin1.  Removed prototype for scm_prlist.
  91
  92         * arbiters.c (prinarb),
  93         async.c (print_async),
  94         debug.c (prindebugobj, prinmemoized),
  95         eval.c (prinprom, prinmacro),
  96         filesys.c (scm_fd_print, scm_dir_print),
  97         kw.c (print_kw),
  98         mallocs.c (prinmalloc),
  99         numbers.c, numbers.h (scm_floprint, scm_bigprint),
 100         smob.h (scm_smobfuns),
 101         srcprop.c (prinsrcprops),
 102         throw.c (prinjb),
 103         unif.c, unif.h (scm_raprin1, rapr1),
 104         variable.c (prin_var): Changed argument `int writing' to
 105         `scm_print_state *pstate'.
 106
 107         * init.c (scm_boot_guile): Moved scm_init_struct upwards so
 108         that it will be called before scm_init_print.
 109
 110         * print.c (scm_prin1): Print states are now allocated when calling
 111         scm_prin1 and then passed around to all printing functions as an
 112         argument.  A cache `print_state_pool' enables reuse of print
 113         states.
 114         (scm_make_print_state): New function.
 115         (scm_iprin1): Adaption to print states.
 116         (scm_iprlist): An initial "hare and tortoise" scan brings down
 117         time complexity to O (depth * N).  (Better time complexity will be
 118         achieved when the printing code is completely rewritten.)
 119
 120 Thu Sep 19 15:33:51 1996  Mikael Djurfeldt  <mdj@kenneth>
 121
 122         * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
 123         scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
 124         Lord's implementation of structs, allowing for tail arrays as
 125         described in the manual. Also fixed some bugs. (Both the interface
 126         and the implementation should be improved.)
 127
 128         * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
 129
 130         * print.c, print.h: Closures now print like #<procedure foo (x)>.
 131         People who whish to see the source can do `(print-enable 'source)'.
 132         Removed #ifdef DEBUG_EXTENSIONS.
 133
 134 Thu Sep 19 00:00:29 1996  Gary Houston  <ghouston@actrix.gen.nz>
 135
 136         * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
 137         integer (assuming for now accepting an integer is a good thing).
 138
 139         * error.c, fports.c: replace use of %S in lgh_error args with %s.
 140         %S will be used instead for write'ing arguments.
 141
 142         * unif.c (scm_transpose_array): change arguments in the SCM_WNA
 143         asserts.  fix a few other asserts.

 146         scm_dimensions_to_unform_array): change args in
 147         SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
 148         strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
 149         scm_substring_fill_x): likewise.
 150         gsubr.c (scm_gsubr_apply): likewise.
 151         eval.c (SCM_APPLY): likewise.
 152
 153         * eval.c (4 places): replace scm_everr with lgh_error or
 154         scm_wrong_num_args.
 155
 156         * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
 157         scm_memory_error): new procedures.
 158 *       scm_everr: deleted.  can use scm_wta, dropping first two args.
 159         scm_error: convert NULL subr to SCM_BOOL_F.
 160
 161         * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
 162         SCM_ARGERR.
 163
 164         * stackchk.c (scm_report_stack_overflow): use lgh_error instead
 165         of scm_wta.
 166
 167         * error.c, error.h: new error keys: scm_arg_type_key,
 168         scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
 169         scm_misc_error_key.
 170         scm_wta: reimplement using lgh_error instead of scm_everr.
 171
 172 Wed Sep 18 17:13:35 1996  Mikael Djurfeldt  <mdj@kenneth>
 173
 174         * gdbint.c: scm_lread now has one more argument.
 175
 176         * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
 177         scm_port_\1; Added mutator scm_set_port_filename_x (used when
 178         loading source from non-file ports, which, e. g., happens when
 179         using the Emacs interface).
 180
 181         * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
 182         object.
 183
 184         * read.c: Added code for recording of positions of source code
 185         expressions; New functions: recsexpr, scm_lreadrecparen;
 186         _scm_make_srcprops --> scm_make_srcprops
 187         (scm_flush_ws): Removed updating of positions counters.  This work
 188         is already done by scm_gen_getc
 189
 190         * read.h: Added prototype for scm_lreadrecparen
 191
 192         * print.c: Added #include "alist.h"
 193

 195
 196         * eq.c: Added #include "ramap.h"
 197
 198         * options.c: Documentation fixes.
 199
 200         * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
 201         (scm_init_srcprop): Adjusted size of initial source-whash.  Name
 202         changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
 203         --> scm_make_srcprops
 204
 205         * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
 206         _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
 207         function calls in the definition of the whash access macros.
 208
 209 Tue Sep 17 01:40:56 1996  Gary Houston  <ghouston@actrix.gen.nz>
 210
 211         * ports.h (scm_port_table): put back file_name, it will be used to
 212         support debugging.  Undo related changes in fports.c, ioext.c,
 213         ports.c, gc.c.
 214
 215 Sun Sep 15 03:58:29 1996  Gary Houston  <ghouston@actrix.gen.nz>
 216
 217         * ports.h (scm_port_table): remove file_name member for now, it seems
 218         undesirable.
 219         * fports.c (scm_open_file): don't set file_name in PTAB.
 220         (prinfport): don't use file_name in PTAB.
 221         * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
 222         * ports.c (scm_add_to_port_table): don't intialize file_name.
 223         (scm_port_file_name): remove for now.
 224         * gc.c (scm_gc_mark): don't mark PTAB file_name.
 225
 226         * fports.h (scm_mkfile): prototype deleted.
 227         * fports.c (scm_mkfile): merged into scm_open_file to simplify.
 228
 229         * debug.c, unif.c: use scm_out_of_range instead of
 230         wta for range errors (ASSERT still needs work).
 231
 232         * error.c, error.h (scm_out_of_range): new procedure.
 233
 234         * error.c, error.h (scm_out_of_range_key): new key.
 235
 236         * posix.c (scm_sync): #else was missing.
 237
 238         * error.c, error.h: append _key to names scm_num_overflow and
 239         scm_system_error.
 240
 241         * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
 242         of consing an empty list.
 243         (SCM_SYSERROR etc.): move into error.c, make them procedures instead
 244         of macros, saves code and string space.
 245         error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
 246         fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
 247         lower case.  Rename scm_syserror_m to scm_syserror_msg.
 248         error.h: prototypes for new procedures.
 249
 250 Sat Sep 14 03:35:41 1996  Gary Houston  <ghouston@actrix.gen.nz>
 251
 252         * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
 253
 254         * error.c, error.h: setup scm_num_overflow key.
 255
 256         * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
 257         Remove definition of SCM_OVSCM_FLOW.
 258
 259         * fports.c (scm_open_file): use SCM_SYSERROR_M.
 260
 261         * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
 262         explicit message and args.
 263
 264         * error.c, error.h, __scm.h: change system_error_sym to
 265         scm_system_error.
 266
 267         * error.c (system_error_sym): remove leading %% from the Scheme name
 268         "%%system-error".
 269
 270         * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
 271
 272 Fri Sep 13 12:58:08 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 273
 274         * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
 275         fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
 276         numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
 277         tags.h, throw.c, variable.h: Name cleanup.  Lots of xxxSCM_yyy
 278         renamed.  (These were introduced by unsupervised name
 279         substitution.)
 280
 281 Fri Sep 13 01:19:08 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 282
 283 *       * print.c: Added code for detection of circular references during
 284         printing.  (init_ref_stack, grow_ref_stack): New functions.  Added
 285         a hook for printing of closures (accessible via print options).
 286         This leads to a split of calls to scm_iprin1 into two classes:
 287         elementary print operations (e. g. the code which prints a smob)
 288         still use scm_iprin1 while top level calls (like scm_display) use
 289         scm_prin1.  scm_prin1 begins by clearing the data structure used
 290         to record reference information.
 291
 292         * print.h: Added declarations of scm_prin1 and scm_prlist.
 293
 294         * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
 295
 296         * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
 297
 298         * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
 299
 300         * error.c (err_head): scm_iprin1 --> scm_prin1
 301
 302         * debug.c: Adjusted header comment.
 303
 304         * tags.h: Typo.
 305
 306 Wed Sep 11 17:55:59 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 307
 308         * strerror.c: Doc fix.
 309
 310 Thu Sep 12 00:00:32 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 311
 312         * gdbint.c (gdb_read): Now possible to run during GC.
 313         (unmark_port, remark_port): New functions.
 314
 315         * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
 316
 317         * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
 318         of allocating a new string object.  Also, increase size by
 319         the factor 2 instead of 1.5.
 320
 321 Wed Sep 11 15:10:38 1996  Petr Adamek  <jimb@floss.cyclic.com>
 322
 323         * __scm.h (SCM_P): Corrected to run under traditional C.
 324
 325         * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
 326         removed.
 327
 328         * async.c: Calls to scm_sysintern corrected.
 329
 330         * async.h (scm_async_clock): Redundant declaration removed.
 331
 332         * continuations.c (scm_dynthrow): Redundant declaration removed.
 333
 334         * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
 335         Definition typos corrected.
 336
 337         * debug.h: Missing declarations of functions in debug.c added
 338         (lots).
 339
 340         * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
 341         Missing declarations to functions in eval.c added.
 342
 343         * filesys.c: Possibly uninitialized variable rv.
 344
 345         * gc.h (scm_object_addr, scm_unhash_name): Missing
 346         declarations of functions defined in gc.c added.
 347
 348         * genio.c: Possible typos str_data -> wstr_data. ???
 349
 350         * genio.c: Possibly unintended shadowing of local variable
 351         `int c' (gotos out of scope of inner `c'). ???
 352
 353         * init.c: Uninitialized `SCM last' may be used.
 354
 355         * ioext.h: (scm_sys_isatty_p): Typo.
 356
 357         * list.h (scm_list_head): Missing prototype for function in
 358         list.c added.
 359
 360         * numbers.c (scm_two_doubles): Changed from extern to static
 361         (is used only within numbers.c).
 362
 363         * numbers.h: Repeated declarations removed.
 364
 365         * ports.h (scm_close_all_ports_except): Declaration for the
 366         function defined in ports.c added.
 367
 368         * posix.h: Missing declarations added.
 369
 370         * procs.h (scm_make_subr_opt): Missing declaration added.
 371
 372         * socket.h (scm_sys_gethost): Missing declaration added.
 373
 374         * socket.h: Redundant declarations removed (they are in fdsocket.h).
 375
 376         * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
 377         Missing declarations added.
 378
 379         * stime.h (scm_get_internal_real_time): Repeated declarations removed.
 380
 381         * struct.c: Uninitialized variable `SCM answer' may be used.
 382
 383         * unif.c (l2ra): Declaration prototype.
 384
 385         * unif.c (scm_array_equal_p): Dummy definition removed (it is
 386         defined in ramap.c).
 387
 388         * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
 389         Redundant declarations removed (they are in ramap.h).
 390
 391         * variable.h (scm_make_udvariable,
 392         scm_make_undefined_variable): Declaration corrected to
 393         correspond variable.c.
 394
 395         * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):

 399
 400         * Makefile.in (distclean): Don't forget to delete fd.h.
 401
 402 Tue Sep 10 14:01:46 1996  Jim Blandy  <jimb@floss.cyclic.com>
 403
 404         * fd.h.in, tags.h: Trivial cleanups.
 405
 406         * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
 407         marksweep.h just declared functions from gc.c.
 408         * gc.h, libguile.h: Don't #include "marksweep.h".
 409         * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
 410         marksweep.o, marksweep.h, marksweep.c, and marksweep.x.  Other
 411         dependencies updated.
 412
 413         * libguile.h: Don't #include "files.h"; it's been deleted.
 414
 415         * files.c (scm_sys_delete_file): Moved to filesys.c.
 416         File is now empty; deleted.
 417         * files.h: Deleted.
 418         * filesys.c: scm_sys_delete_file is now here.  Remove
 419         #if's; they seem to rely on remnants of an old portability
 420         regimen.  If the problems come up again, solve them properly,
 421         using autoconf.  Specifically: Don't test M_SYSV, and #define
 422         remove to be unlink if it's #defined; don't use remove just
 423         because HAVE_STDC_HEADERS is #defined.
 424         * filesys.h: Add declarations for scm_sys_delete_file.
 425         * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
 426         files.o, files.h, files.c, and files.x.
 427         * init.c: Don't #include "files.h", and don't call scm_init_files.
 428
 429         Use SCM_P instead of PROTO; the latter intrudes on the user's
 430         namespace.
 431         * params.h: Deleted; definition of SCM_P moved to...
 432         * __scm.h: ... here, where it replaces PROTO macro.
 433         * libguile.h, smob.h: Don't #include "params.h".
 434         * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
 435         smob.h: Fix prototypes accordingly.
 436         * Makefile.in: Update dependencies.
 437         (inner_h_files): Remove params.h.
 438
 439         * gc.c: #include "gc.h"; every module should include its header,
 440         to let the compiler cross-check the declarations against the
 441         definitions.
 442
 443         * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
 444         simpos.h: #include "libguile/__scm.h".

 446 Mon Sep  9 20:00:15 1996  Jim Blandy  <jimb@floss.cyclic.com>
 447
 448         * init.c: Don't forget to #include smob.h and init.h.
 449         * Makefile.in: Dependencies updated.
 450
 451         * smob.h: Use PROTO instead of #if __STDC__.
 452
 453         * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
 454
 455         * __scm.h: Doc fixes.
 456
 457         * __scm.h, libguile.h: Use "quotes" in the #includes, not
 458         <angles>; this allows `make depends' to work properly.
 459
 460         * libguile.h: #include smob.h and pairs.h before the others; they
 461         define typedefs used by other headers.
 462
 463         C files should #include only the header files they need, not
 464         libguile.h (which #includes all the header files); the pointless
 465         recompilation was wasting my time.
 466         * Makefile.in (all .o dependency lists): Regenerated.
 467         * libguile.h: Don't try to get a definition for size_t here...
 468         * __scm.h: Do it here.
 469         * _scm.h: Since this is the internal libguile header, put things
 470         here that all (or a majority) of the libguile files will want.
 471         Don't #include <libguile.h> here; that generates dependencies on
 472         way too much.  Instead, get "__scm.h", "error.h", "pairs.h",
 473         "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",

 574
 575         * print.h, read.h: #include "options.h", since everyone who uses
 576         either of these files will need that.
 577
 578         * smob.h: #include "ports.h", "genio.h", and "print.h", since
 579         anyone who uses this file will need them to define the smob
 580         printing functions.  Also, get markers.h, since people will need
 581         to #define the mark functions.
 582
 583         * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
 584         * ports.h: ... to here.
 585
 586         * ports.h (scm_port_table_size): Explicitly give type as 'int';
 587         don't rely on archaic C default type rules.
 588
 589         * fports.h: #include "libguile/ports.h", since you need that in
 590         order to parse this.
 591
 592         * genio.h: #include "libguile/print.h", because you need that to
 593         parse this; don't bother #including "ports.h", since print.h gets
 594         that.
 595
 596         * error.h: Don't #include "pairs.h"; _scm.h will do that now.
 597
 598         * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
 599         this; it's now a reference to an element of *scm_root.
 600
 601         * debug.h: Don't #include "options.h"; the compiler won't be able
 602         to find that once the headers are installed; instead, #include
 603         "libguile/options.h".
 604         * gc.h: Same, with marksweep.h.
 605         * mbstrings.h: Same, with symbols.h.
 606         * scmhob.h: Same, with _scm.h.
 607         * smob.h: Same, with params.h.
 608
 609         * Makefile.in (depends): Don't nuke scmconfig.h and the generated
 610         C files; there's no need for this, and it forces recompilations
 611         unnecessarily.

 655         * Makefile.in (libpath.h): Omit trailing slash from path.  We
 656         shouldn't require it of users, so why put it here?
 657
 658         Move code to initialize and search %load-path from ice-9 to C
 659         code, so we can use the load-path to find the ice-9 boot code;
 660         this makes it easier to run Guile without installing it.  See
 661         corresponding changes in guile/Makefile.in.
 662         * feature.c: Move stuff concerned with the load path to load.c.
 663         (scm_compiled_library_path): Deleted.
 664         Don't #include libpath.h here.
 665         * feature.h: Don't mention scm_compiled_library_path.
 666         * load.c: #include "libpath.h" here, as well as <sys/types.h>,
 667         <sys/stat.h>, and <unistd.h> (if present).
 668         (R_OK): #define if the system hasn't deigned to.
 669         (scm_loc_load_path): New variable.
 670         (scm_init_load_path, scm_sys_search_load_path,
 671         scm_sys_try_load_path): New functions.
 672         (scm_init_load): Initialize scm_loc_load_path to point to the
 673         value cell of the Scheme %load-path variable.
 674         * load.h: Add declarations for scm_sys_search_load_path,
 675         scm_sys_try_load_path.
 676         * init.c: Call scm_init_load_path.
 677         * Makefile.in (feature.o, load.o): Dependencies updated.
 678
 679         * load.c, load.h: Rewrite using PROTO macro.
 680
 681 Thu Sep  5 01:54:33 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 682
 683         * gc.c (scm_cellp): New function: C predicate to determine if an
 684         SCM value can be regarded as a pointer to a cell on the heap.
 685
 686         * gc.h: Added declaration of scm_cellp.
 687
 688         * gdb_interface.h: New file: The GDB interface header from the GDB
 689         distribution.
 690
 691         * gdbint.c: New file: GDB interface.
 692
 693         * gdbint.h: New file: GDB interface.
 694
 695         * libguile.h: Added #include <libguile/gdbint.h>.
 696
 697         * init.c (scm_boot_guile): Added scm_init_gdbint.
 698
 699         * Makefile.in: Added gdb_interface.h, gdbint.[hc].
 700         Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
 701         found if object files and source are kept separate).
 702
 703 Wed Sep  4 14:35:02 1996  Jim Blandy  <jimb@floss.cyclic.com>
 704
 705         * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
 706
 707 Wed Sep  4 01:30:47 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 708
 709         * configure.in: Don't substitute the values of TCL_SRC_DIR and
 710         TK_SRC_DIR; they're not relevant any more.
 711
 712         * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
 713         * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
 714
 715 Wed Sep  4 00:55:49 1996  Jim Blandy  <jimb@floss.cyclic.com>
 716
 717         * PLUGIN/guile.config (xtra_cflags): Include .. in the header
 718         search path, so we can find the <libguile/MUMBLE.h> headers.
 719
 720         * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
 721
 722         * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
 723         implicit in the .c.o rule.
 724         (.c.x): Don't mention ALL_CFLAGS here; its value is included in
 725         $(CC) already.
 726
 727         Put the library path in a header file, instead of passing it on
 728         the command line in every compilation.
 729         * Makefile.in (libpath.h): New target.
 730         (feature.o): Depend on libpath.h.
 731         (clean): Delete libpath.h.
 732         (ALL_CFLAGS): Don't use -DLIBRARY_PATH here.  Instead ...
 733         * feature.c: ... #include "libpath.h" here.
 734         * .cvsignore: Ignore libpath.h.
 735
 736 *       Don't install the unwashed masses of Guile header files in the
 737         main #include path; put most of them in a subdirectory called
 738         'libguile'.  This avoids naming conflicts between Guile header
 739         files and system header files (of which there were a few).
 740         * Makefile.in (pkgincludedir): Deleted.
 741         (innerincludedir): New variable; this and $(includedir) are enough.
 742         (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
 743         (installed_h_files): Divide this up.  Now this variable lists
 744         those header files which should go into $(includedir) (i.e. appear
 745         directly in the #include path), and ...
 746         (inner_h_files): ... this new variable says which files appear in
 747         a subdirectory, and are referred to as <libguile/mumble.h>.
 748         (h_files): List them both.
 749         (install): Create innerincludedir, not pkgincludedir.  Put
 750         the installed_h_files and inner_h_files in their proper places.
 751         (uninstall): Corresponding changes.
 752         * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
 753         continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
 754         feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
 755         ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
 756         mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
 757         print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
 758         sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
 759         strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
 760         tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
 761         vports.h, weaks.h: Find __scm.h in its new location.
 762         * __scm.h: Find scmconfig.h and tags.h in their new locations
 763         (they're both "inner" files).
 764
 765 Tue Sep  3 20:27:35 1996  Jim Blandy  <jimb@floss.cyclic.com>
 766
 767         * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
 768
 769 Tue Sep  3 19:53:00 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 770
 771         * posix.c: Doc fixes.
 772
 773 Mon Sep  2 15:22:40 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 774
 775         * socket.c: Don't include a prototype for inet_aton; just use a
 776         K&R style declaration, to avoid warnings but minimize the chance
 777         of conflicts with the system.
 778
 779         On NextStep, <utime.h> doesn't define struct utime, unless we
 780         #define _POSIX_SOURCE before #including it.
 781         * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
 782         * acconfig.h: New comment text for above CPP symbol.
 783         * configure.in: Call it.
 784         * posix.c: #define _POSIX_SOURCE if it seems necessary.
 785
 786         * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
 787         in the list.
 788         * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
 789         testing for __EMX__.
 790
 791         * posix.c: #include <libc.h>, if it exists.
 792
 793         * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
 794         don't even know if the latter exists.
 795
 796         * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
 797         s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
 798         s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
 799
 800         * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
 801         header files don't.
 802         (scm_init_posix): Use them when initializing the Scheme constants
 803         of the same name.
 804
 805 Fri Aug 30 16:01:30 1996  Jim Blandy  <jimb@floss.cyclic.com>
 806
 807         * Makefile.in (libdir, includedir, bindir): Use the
 808         autoconf-supplied values, instead of deriving them ourselves.
 809         (pkgincludedir, datadir, pkgdatadir): New variables.
 810         (install, uninstall): Put the header files in a special
 811         subdirectory, not in the main search path.
 812
 813         * Makefile.in (ALL_CFLAGS): Provide the proper value for
 814         LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
 815
 816         * Makefile.in (IMPLPATH): Deleted; never used.
 817
 818         * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
 819         on the Tcl/Tk source any more.
 820         (INCLUDE_CFLAGS): Remove references to the above.
 821
 822         * Makefile.in (version.o): Corrected dependencies.
 823
 824 Thu Aug 29 23:06:19 1996  Thomas Morgan  <tmorgan@gnu.ai.mit.edu>
 825
 826         * libguile.h: #include "version.h"
 827
 828         * init.c (scm_boot_guile): Call scm_init_version.
 829         * gscm.c (gscm_run_scm): Call scm_init_version.
 830
 831         * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
 832         GUILE_VERSION): AC_DEFINE these.
 833         (acconfig.h): #undef the above symbols.
 834
 835         * Makefile.in (libobjs): Add version.o.
 836         (installed_h_files): Add version.h.
 837         (c_files): Add version.c.
 838         (gen_c_files): Add version.x.
 839         (version.o): New rule.
 840         (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
 841         chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
 842         fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
 843         genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
 844         mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
 845         objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
 846         procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
 847         simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
 848         strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
 849         throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
 850         weaks.o): Add version.h to dependency lists.
 851         (markers.o): Remove duplicate rule.
 852
 853         * version.h: New file.
 854
 855         * version.c: New file.
 856
 857 Thu Aug 29 15:21:39 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 858
 859         * symbols.c (scm_strhash): scm_downcase is now a function, not an
 860         array; use it appropriately.  Since GCC is quite happy to
 861         subscript functions, it never warned us about this; we should use
 862         -Wpointer-arith in the future.  I guess we never tested
 863         case-insensitivity.
 864
 865 Wed Aug 28 18:52:22 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 866
 867         * socket.c: Doc and copyright fixes.
 868
 869 Sat Aug 24 05:29:19 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 870
 871         * debug.c: Fixed and improved gdb support.
 872
 873 Fri Aug 23 18:00:16 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 874
 875         * socket.c: Added declaration of inet_aton to avoid compiler
 876         warning.  (Hope this solution is correct.)
 877
 878         * stime.c: Added declaration of ftime.  (This is missing in
 879         Solaris 2 headers.)
 880
 881 Fri Aug 23 02:03:32 1996  Gary Houston  <ghouston@actrix.gen.nz>
 882
 883         * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
 884
 885         * Makefile.in (c_files): add strerror.c.
 886
 887         * strerror.c: new file from Emacs' sysdep.c.
 888         maybe configure should also check for sys_errlist.
 889
 890         * configure.in (AC_REPLACE_FUNCS): add strerror.
 891
 892 Fri Aug 23 03:02:46 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 893
 894         * debug.c (scm_init_debug): Added initialization for
 895         scm_evaluator_traps.
 896
 897         * debug.h, debug.c: Various name changes.
 898         (Mostly prefixing with SCM_.)  Renamed "debug-options" -->
 899         "debug-options-interface".  See commentary in options.c.
 900
 901         * options.h, options.c: Options now have documentation strings.
 902         Also added a long explanatory commentary.
 903
 904         * eval.c, print.h, print.c, read.h, read.c: Modifications to
 905         run-time options.
 906
 907         * gscm.c, init.c, root.c, throw.c: Bug fixes:
 908         last_debug_info_frame is now updated in all cases.
 909
 910         * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
 911         checking.
 912
 913 Thu Aug 22 17:34:17 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 914
 915         * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
 916         Added option STACK_CHECKING.
 917
 918 Tue Aug 20 18:48:40 1996  Mikael Djurfeldt  <djurfeldt@nada.kth.se>
 919
 920         * Makefile.in: Added {debug,options,srcprop}.{h,c}
 921
 922         * __scm.h: Removed symbols for debugging support.
 923
 924         * acconfig.h: Added symbols for debugging support.
 925
 926 *       * configure.in: Added user option for debugging support.
 927         --enable-debug will include the debugging code into libguile.a.
 928
 929         * continuations.c (scm_make_cont): Enlarged the #if 0 around
 930         scm_relocate_chunk_to_heap.
 931
 932 *       * debug.c: New file: low-level debugging support.  It also
 933         includes support for debugging with gdb.  (The extensions to gdb
 934         are written by Per Bothner at Cygnus.)
 935
 936         * debug.h: New file: low-level debugging support.
 937
 938 *       * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
 939         argument pairs.  Extensive modifications to the debugging
 940         evaluator.  Added "SECTION:" commentaries to clarify what happens
 941         when, during double compilation.  Renamed EVALIMP --> EVALIM.
 942         Renamed EVAL --> XEVAL.  Removed function evalcar.  Defined
 943         evalcar to scm_eval_car.  Added explanation of "EVAL" symbols to
 944         the beginning of the file.  New procedure: scm_unmemocopy.
 945         Added some global state variables needed by the debugging
 946         evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
 947         check_entry, check_apply, check_exit, debug_options and
 948         evaluator_traps.  New acro: undefine.
 949
 950         * eval.h: Renamed EVAL --> XEVAL.
 951
 952         * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
 953         --> scm_make_weak_key_hash_table.
 954
 955         * init.c (scm_restart_stack, scm_boot_guile): Added initialization
 956         of SCM_DFRAME.  Added calls to scm_init_{debug,options,srcprop}.
 957
 958         * libguile.h: Conditionally include debug.h
 959
 960 *       * objprop.c (scm_object_properties, scm_set_object_properties_x):
 961         scm_object_properties shouldn't return handle.  `handle' now gets
 962         initialized in scm_set_object_properties_x.  scm_object_properties
 963         doesn't any longer create an entry in scm_object_whash.
 964
 965 *       * options.c: New file: handling of run time options.
 966
 967         * options.h: New file: handling of run time options.
 968
 969         * posix.c (scm_getpgrp): Cast pointer to getpgrp.
 970
 971 *       * print.c: New procedure: scm_print_options
 972
 973         * print.h: Defines for print options.
 974
 975 *       * read.c: New procedure: scm_read_options
 976
 977         * read.h: Defines for reader options.
 978
 979         * root.h: Added scm_source_whash among scm_sys_protects.
 980
 981 *       * srcprop.c: New file: source properties.
 982
 983         * srcprop.h: New file: source properties.
 984
 985         * throw.c (jbsmob): Jump buffers are now correctly allocated.
 986         (Bug found by A. Green.)
 987
 988 *       * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
 989
 990         * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
 991
 992 Thu Aug 15 02:05:14 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 993
 994         * libguile.h: #include "objprop.h"; I guess this was forgotten.
 995
 996         * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
 997         and should be called by the final client.

1001         * gc.h: Use the PROTO macro when declaring functions.
1002         * gc.c: Use the PROTO macro when declaring static functions.
1003         Remove the CPP hair around function definitions.
1004
1005         * gc.c (scm_init_storage): Initialize scm_asyncs.
1006
1007         * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
1008         preprocessor symbol; "__scm.h" is where it might get #defined.
1009         * __scm.h: Similar: #include <scmconfig.h> before testing
1010         HAVE_LIMITS_H.
1011
1012         * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
1013
1014 Fri Aug  9 11:09:28 1996  Jim Blandy  <jimb@totoro.cyclic.com>
1015
1016 *       * init.c (scm_boot_guile): Add init_func argument; call
1017         (*init_func) instead of calling scm_appinit; it's ucky to
1018         hard-code names for the user's procedures.
1019         * init.h (scm_boot_guile): Adjust declaration.
1020
1021         * __scm.h (PROTO): New macro, for declaring functions with
1022         prototypes.
1023
1024         * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
1025         eliminate all the __STDC__ conditionals.
1026         (scm_boot_guile): Add declaration.
1027         * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
1028         Remove __STDC__ conditionals around function definitions; the
1029         declarations in init.h will provide the same information, more
1030         usefully.
1031
1032         * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
1033         complain about it in the error message; the error message is
1034         adequate without that note, and there's nothing the user can do
1035         about it.
1036
1037 Wed Aug  7 14:14:46 1996  Jim Blandy  <jimb@totoro.cyclic.com>
1038
1039         * Makefile.in (ancillary): Drop def.sed.
1040
1041         * posix.c (scm_init_posix): Use numeric values, rather than
1042         CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
1043         F_OK.  The symbols aren't available on some systems, and I'm
1044         pretty sure their values are fixed by common widespread practice.
1045         * ioext.c (scm_init_ioext): Code here defined them too; remove it.
1046
1047         More functions unavailable on some systems.
1048         * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
1049         tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
1050         check for.
1051         * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
1052         * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
1053         scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
1054         bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
1055         stub that signals an error as the #else.
1056
1057         * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
1058
1059 Wed Aug  7 06:28:42 1996  Gary Houston  <ghouston@actrix.gen.nz>
1060
1061         * Fixes motivated by Petr Adamek <adamek@mit.edu>:
1062
1063         * unif.c: include ramap.h.
1064
1065         * read.c (endif): case_insensative_p renamed case_insensitive_p.
1066
1067         * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
1068
1069         * ports.c: include sys/ioctl.h.
1070
1071         * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
1072
1073         * configure.in: check for sys/ioctl.h.
1074
1075         * ports.c: include <malloc.h> not "malloc.h".
1076
1077         * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
1078
1079         * fports.c: remove ttyname and tmpnam declarations.
1080
1081         * posix.c: fewer ttyname declarations.
1082
1083         * fports.c: include <string.h> not "string.h".
1084
1085         * init.c, ioext.c: include string.h and unistd.h.
1086
1087         * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
1088
1089         * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
1090         genio.c, simpos.c, vports.c: include string.h.
1091
1092         * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
1093
1094         * fdsocket.c (getsockopt, setsockopt): change type of optlen from
1095         scm_sizet to int.
1096         (scm_addr_buffer_size): change type from scm_sizet to int.
1097         (accept, getsockname, getpeername, recvfrom): change type of tmp_size
1098         from scm_sizet to int.
1099
1100         * error.c: include unistd.h.
1101
1102         * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
1103         defined.
1104
1105         * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
1106
1107         * __scm.hd, def.sed: deleted.
1108
1109 Tue Aug  6 14:49:08 1996  Jim Blandy  <jimb@totoro.cyclic.com>
1110
1111         Changes for NeXT, suggested by Robert Brown.
1112         * configure.in: Call AC_TYPE_MODE_T.
1113         (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
1114         NeXT.  Put header file list in alphabetical order.
1115         * configure, scmconfig.h.in: Regenerated.
1116         * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
1117
1118         * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
1119         for strerror.
1120
1121         * acconfig.h: New file, providing documentation for the CPP
1122         symbols defined in configure.in
1123         * acconfig-1.5.h: Removed; superceded by the above.
1124
1125 Sat Aug  3 01:27:14 1996  Gary Houston  <ghouston@actrix.gen.nz>
1126
1127         * ioext.c (scm_sys_fdopen): fix the port-table assignment.
1128
1129 *       * fports.c (scm_open_file): don't return #f, throw error.
1130
1131 *       * ioext.c (fileno): renamed from %fileno.
1132         (soft-fileno): deleted.
1133
1134         * ports.c (scm_port_revealed): don't need to check for -1 from
1135         scm_revealed_count.
1136         (scm_set_port_revealed_x): return unspecified, not #f.
1137
1138 *       * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
1139
1140         * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
1141
1142         * scmconfig.h.in: add HAVE_STRUCT_LINGER.
1143
1144         * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
1145
1146 Thu Aug  1 02:58:39 1996  Jim Blandy  <jimb@totoro.cyclic.com>
1147
1148         * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
1149         This is necessary on Ultrix, and doesn't hurt portability.
1150
1151         * Makefile.in (dist-dir): New target, implementing a new dist system.
1152         (installed_h_files): Put in alphabetical order.
1153         Remove duplicate entries for markers.h and unif.h.
1154         (c_files): Remove duplicate entries for markers.c.
1155         (ancillary): Renamed from anillery; all uses changed.  Remove
1156         PLUGIN; it's a directory, and needs special treatment in dist-dir.
1157         Remove all the ../doc/* files; doc/Makefile.in handles that.
1158
1159         * Makefile.in (libobjs): Remove duplicate entry for markers.o.
1160
1161         * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
1162         every if must have an else, or else the whole command has a
1163         non-zero exit code whenever the if's condition is false.
1164
1165 Thu Aug  1 08:22:24 1996  Gary Houston  <ghouston@actrix.gen.nz>
1166
1167         * posix.c: include string.h.
1168
1169 Wed Jul 31 23:43:05 1996  Gary Houston  <ghouston@actrix.gen.nz>
1170
1171 *       * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
1172         have been once.
1173
1174 *       * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
1175         Remove leading % from scheme names.
1176         Do not return error values, call SCM_SYSERROR or similar.
1177
1178         * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
1179
1180 Wed Jun 12 00:28:31 1996  Tom Lord  <lord@beehive>
1181
1182         * struct.c (scm_init_struct): new file.
1183
1184 Fri Jun  7 14:02:00 1996  Tom Lord  <lord@beehive>
1185
1186         * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
1187         (scm_list_head): added list-head for rapidly chopping argument
1188         lists off of longer lists (and similar).
1189
1190 Tue Jun  4 09:40:33 1996  Tom Lord  <lord@beehive>
1191
1192         * objprop.c (scm_object_property): assq the cdr of the whash
1193         handle for obj, not the handle itself.
1194
1195 Mon Jun  3 17:19:30 1996  Tom Lord  <lord@beehive>
1196
1197         * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
1198         weak hash tables last of all marking to avoid an obscure gc bug.
1199         WARNING: circular lists stored in a weak hash table will hose us.
1200
1201 Fri May 24 09:53:39 1996  Tom Lord  <lord@beehive>
1202
1203         * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
1204         new functions similar to scm_substring_move_left_x and
1205         scm_substring_move_right_x.
1206
1207 Wed May 22 20:07:01 1996  Tom Lord  <lord@beehive>
1208
1209         * init.c (scm_boot_guile): prevent gc with scm_block_gc not
1210         scm_gc_heap_lock!
1211
1212 Wed May 15 16:13:29 1996  Tom Lord  <lord@beehive>
1213
1214         * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
1215
1216 Thu May  9 09:33:17 1996  Tom Lord  <lord@beehive>
1217
1218         * strports.c (scm_strprint_obj): convenience function.  C for
1219         (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
1220
1221         * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
1222                 removed to a separate library
1223
1224         * init.c (scm_boot_guile): copied from guile-tcl.c.
1225         Initialization specific to tcl interpreters removed.
1226
1227 Wed May  8 15:07:37 1996  Tom Lord  <lord@beehive>
1228
1229         * ports.c (scm_ports_prehistory): size malloced here doesn't
1230         matter so long as it is non-0 (got rid of "* 4").
1231
1232 Tue May  7 11:43:37 1996  Tom Lord  <lord@beehive>
1233
1234         * gscm.h: gscm_mkarray eliminated (presumably was not being used
1235         since its definition was bogus).
1236
1237 Mon May  6 13:02:56 1996  Tom Lord  <lord@beehive>
1238
1239         * mallocs.[ch]: back again (for rx at least).
1240
1241 Wed Apr 17 08:54:20 1996  Tom Lord  <lord@beehive>
1242
1243         * ports.c: removed functions relating to the mapping between ports
1244         and descriptors.   (That stuff is unix-specific and should be collected
1245         in a separate library).
1246
1247         * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
1248         (Tom Mckay@avanticorp.com)
1249
1250 Mon Apr 15 14:16:55 1996  Tom Lord  <lord@beehive>
1251
1252         * gc.c (scm_gc_sweep): Immediates in weak vectors were not
1253         handled correctly (SCM_FREEP was applied to them) -- test for
1254         NIMP.  Keys in weak hash tables were spuriously (though harmlessly)
1255         being overwritten with #f.   (brown@grettir.bibliotech.com)
1256
1257 Tue Apr  2 22:25:00 1996  Tom Lord  <lord@beehive>
1258
1259         * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs
1260         for a specific symbol or for all symbols.
1261
1262 Mon Apr  1 10:34:55 1996  Tom Lord  <lord@beehive>
1263
1264         * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak
1265         keys and weak values confused).
1266
1267 Thu Mar 14 22:20:20 1996  Tom Lord  <lord@beehive>
1268
1269         * list.c (scm_last_pair): map '()=>'()
1270
1271 Wed Mar 13 16:43:34 1996  Tom Lord  <lord@beehive>
1272
1273         * pairs.c, hashtab.c, list.c, alist.c append.c, sequences.c:
1274         Generalized assoc and hash-table functions.
1275         Factored pairs.c into multiple files.
1276
1277 Fri Mar  8 14:44:39 1996  Tom Lord  <lord@beehive>
1278
1279         * gscm.c (gscm_run_scm): got rid of objprop.
1280
1281 Fri Mar  1 10:39:52 1996  Tom Lord  <lord@beehive>
1282
1283         * genio.c (scm_getc):
1284         NOTE: fgetc may not be interruptable.
1285
1286         * procprop.c (scm_stand_in_scm_proc):
1287         NOTE: don't use a alist here.
1288         (scm_set_procedure_properties_x): fix type checking throughout this file.
1289
1290         * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
1291
1292         * ports.c (scm_remove_from_port_table): adjust scm_mallocated
1293         after freeing part of the port table.
1294
1295 Thu Feb 29 16:21:17 1996  Tom Lord  <lord@beehive>
1296
1297         * strports.c (scm_mkstrport):
1298         * vports.c (scm_make_soft_port): allocate a port table entry
1299         (possibly triggering gc) before setting the tag of the corresponding
1300         ports handle.
1301
1302         * pairs.c (scm_delq_x): never throw an error.
1303
1304         * vectors.c (scm_make_vector): made the default vector fill argument
1305         into '() (much more useful than the previous value, "#unspecified")
1306
1307 Mon Feb 26 17:19:09 1996  Tom Lord  <lord@beehive>
1308
1309         * ports.c (scm_add_to_port_table): Added fields
1310         to port table entries: file_name, line_num, col.
1311         Update these in open_file, gen_getc and gen_ungetc.
1312         Added procedures to access those fields.
1313
1314 Sun Feb 25 00:10:36 1996  Tom Lord  <lord@beehive>
1315
1316         * procs.c (scm_make_subr_opt): new entry point for making

1320
1321         * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
1322
1323 Fri Feb 23 10:26:29 1996  Tom Lord  <lord@beehive>
1324
1325         * numbers.c (scm_exact_p): This function no longer
1326         implements "integer?".
1327
1328 Thu Feb 22 20:56:16 1996  Tom Lord  <lord@beehive>
1329
1330         * gc.c (scm_gc_end): simulate a signal at the end of each GC.
1331         (scm_gc_stats): return an assoc of useful data.  Replaces "room"
1332         and the stats reporting formerlly built into repl.
1333
1334         * repl.[ch]: removed.
1335         GC statistics keeping moved to gc.c.
1336         Other statistics keeping can be done from Scheme.
1337         REPLS are now written in Scheme.
1338
1339 Wed Feb 21 10:28:53 1996  Tom Lord  <lord@beehive>
1340
1341         * cnsvobj.c (gscm_is_gscm_obj): new file for old functions (icky
1342         conservatively marked objects).
1343
1344         * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
1345
1346         * error.c (scm_init_error): init system_error_sym here, not in repl.c.
1347
1348         * feature.c (scm_compiled_library_path): moved here from repl.c.
1349         This file is for stuff relating specifically to Scheme libraries
1350         like slib.
1351
1352         * eval.c (scm_m_define): don't give warning about redefinition, don't

1354
1355         NOTE: this should throw a resumable exception with parameters --
1356         the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
1357
1358         * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
1359
1360         * error.c: scm_warn eliminated.

1379         * strports.c: don't reveal the port's string to the caller
1380         because it changes size.

1417
1418         * root.c &c.: collected stack-specific global state.
1419         linum/colnum etc *should* be port-specific state.

1422         initialization to fix a race condition.

1448         set the multi_byte flag correctly in symbols.  This is wrong.
1449         intern_obbary_soft and msymbolize should take an extra parameter.
1450         Also, weird multibyte symbols don't print correctly.
1451         The weird symbol syntax is also a bit bogus (emacs doesn't quite
1452         cope).
