ice-9/ChangeLog

   1 Sat May 31 18:57:12 1997  Gary Houston  <ghouston@actrix.gen.nz>
   2
   3         * boot-9.scm: signal-handler, alarm-thunk: removed.
   4         don't define ticks-interrupt etc.
   5         top-repl: install signal handlers for SIGINT, SIGFPE, SIGSEGV, SIGBUS
   6         during call to scm-style-repl.
   7
   8 Fri May 30 18:08:10 1997  Jim Blandy  <jimb@floss.cyclic.com>
   9
  10         * slib.scm (slib:load): Use primitive-load-path instead of
  11         basic-load.  This is probably wrong, but hopefully the entire
  12         source access system will be revised soon anyway, and this will
  13         make require behave more like Emacs Lisp's require.  If this
  14         breaks something, please let me know.  Maybe this is real dumb.
  15
  16 Thu May 29 02:36:48 1997  Jim Blandy  <jimb@floss.cyclic.com>
  17
  18         * regex.scm: Add a module declaration.  Use DEFINE-PUBLIC everywhere.
  19         * boot-9.scm: If the `regex' feature is present, use the module
  20         (ice-9 regex).
  21
  22 Tue May 27 22:48:14 1997  Tim Pierce  <twp@twp.tezcat.com>
  23
  24         * regex.scm: New file.
  25         * Makefile.am (subpkgdata_DATA): Add regex.scm.
  26         * Makefile.in: Regenerated.
  27
  28 Mon May 26 17:24:48 1997  Jim Blandy  <jimb@totoro.cyclic.com>
  29
  30         * COPYING, boot-9.scm, debug.scm, emacs.scm, expect.scm, gtcl.scm,
  31         gwish.scm, hcons.scm, lineio.scm, mapping.scm, nonblocking.scm,
  32         oldprint.scm, poe.scm, r4rs.scm, source.scm, tags.scm, test.scm,
  33         threads.scm: New address for FSF.
  34
  35 Fri May 16 04:09:45 1997  Jim Blandy  <jimb@floss.cyclic.com>
  36
  37         * debug.scm: Update copyright years; this file has been worked on
  38         in 1997.
  39
  40 Thu May 15 07:56:08 1997  Gary Houston  <ghouston@actrix.gen.nz>
  41
  42         * expect.scm: use gettimeofday instead of get-internal-real-time
  43         and use a floating point timeout when calling select.  Untested,
  44         since the regex library is currently AWOL.
  45
  46 Wed May 14 21:00:30 1997  Jim Blandy  <jimb@floss.cyclic.com>
  47
  48         * boot-9.scm (eval-string): Function deleted; it was already
  49         implemented in C, so there's no point in making a divergable copy
  50         here.
  51
  52 Tue May 13 16:40:06 1997  Jim Blandy  <jimb@floss.cyclic.com>
  53
  54         * Makefile.in: Regenerated, using automake-1.1p.
  55
  56 Tue May 13 16:40:06 1997  Jim Blandy  <jimb@floss.cyclic.com>
  57
  58         * Makefile.in: Regenerated, using automake-1.1p.
  59
  60 Tue May 13 02:48:49 1997  Gary Houston  <ghouston@actrix.gen.nz>
  61
  62         * boot-9.scm (error-catching-loop): don't read a line from
  63         current input when quit is encountered, the previous change
  64         fixes this too.
  65
  66 Mon May 12 19:00:21 1997  Jim Blandy  <jimb@floss.cyclic.com>
  67
  68         * boot-9.scm (scm-style-repl): After reading an expression,
  69         consume any trailing newline (perhaps preceded by whitespace), to
  70         avoid screwing up GDB.  More detail in comments.
  71
  72 Mon May  5 13:18:38 1997  Jim Blandy  <jimb@floss.cyclic.com>
  73
  74         * Makefile.am (ETAGS_ARGS): New variable, since we're not treating
  75         the Scheme code like code yet.
  76         * Makefile.in: Resrac,husrched.
  77
  78 Wed Apr 30 15:25:15 1997  Marius Vollmer  <mvo@zagadka.ping.de>
  79
  80         * boot-9.scm (link-dynamic-module): Do not catch errors from
  81         dynamic-link and dynamic-call.  When the shared library exists it
  82         is now assumed to be suitable for a dynamic C module.
  83
  84 Fri Apr 25 21:21:35 1997  Marius Vollmer  <mvo@zagadka.ping.de>
  85
  86         * boot-9.scm (process-use-modules): New function to support the
  87         use-modules macro
  88         (use-modules): throw an error iff one of the requested modules
  89         can't be found.
  90
  91 Tue Apr 29 06:54:46 1997  Gary Houston  <ghouston@actrix.gen.nz>
  92
  93         * boot-9.scm: don't define timer-thunk or gc-thunk.
  94
  95 Sun Apr 27 17:56:09 1997  Jim Blandy  <jimb@floss.cyclic.com>
  96
  97         * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
  98
  99         * Makefile.am (subpkgdatadir): Use "ice-9" instead of "@module@";
 100         we're not using AM_INIT_GUILE_MODULE any more.
 101         * Makefile.in: Regeneratitetedrerd.
 102
 103 Thu Apr 24 01:33:33 1997  Jim Blandy  <jimb@floss.cyclic.com>
 104
 105         Get 'make dist' to work again.
 106         * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
 107         * Makefile.in: Regenerated, like two tons of fleas.
 108
 109         Changes for reduced Guile distribution: one configure script,
 110         no plugins.
 111         * configure.in, configure: Removed.
 112         * Makefile.in: Regenerated.
 113
 114 Sat Apr 19 08:03:50 1997  Jim Blandy  <jimb@floss.cyclic.com>
 115
 116         * boot-9.scm (eval-string, command-line, load-user-init): New
 117         functions.
 118
 119 Sat Apr 12 08:27:05 1997  Gary Houston  <ghouston@actrix.gen.nz>
 120
 121         * boot-9.scm (log10): defined.
 122
 123 Tue Apr  1 17:46:49 1997  Gary Houston  <ghouston@actrix.gen.nz>
 124
 125         * expect.scm (expect-select): correct the millisecond timeout
 126         arithmetic (from Marko.Kohtala@ntc.nokia.com).
 127
 128 Mon Mar 31 03:23:19 1997  Gary Houston  <ghouston@actrix.gen.nz>
 129
 130         * boot-9.scm (open-input-pipe, open-output-pipe): defined here
 131         instead of in libguile.
 132         (tm:sec etc.) new accessors for broken-down time.
 133         (set-tm:sec etc.) new setters for broken-down time.
 134
 135 Thu Mar 27 05:06:00 1997  Gary Houston  <ghouston@actrix.gen.nz>
 136
 137         * boot-9.scm (netent:addrtype, servent:port): added missing
 138         procedures.
 139         (netent:net, servent:proto): repaired.
 140         (utsname:sysname etc.): new accessors for uname.
 141
 142 Tue Mar 25 03:04:03 1997  Gary Houston  <ghouston@actrix.gen.nz>
 143
 144         * boot-9.scm (sockaddr:fam, sockaddr:path, sockaddr:addr,
 145         sockaddr:port): new functions.
 146
 147 Wed Mar 19 04:50:34 1997  Gary Houston  <ghouston@actrix.gen.nz>
 148
 149         * boot-9.scm: define accessor procedures for the objects returned
 150         by getpw, getgr, gethost, getnet, getproto, getserv (e.g.,
 151         passwd:name, where the first component is the name of the C structure
 152         and the second is the unprefixed C member name.)
 153
 154 Tue Mar 18 18:39:31 1997  Gary Houston  <ghouston@actrix.gen.nz>
 155
 156         * boot-9.scm (setpwent, setgrent, sethostent, setnetent, setprotoent,
 157         setservent): no longer take an argument, it was bogus.
 158
 159 Thu Mar 13 00:13:41 1997  Gary Houston  <ghouston@actrix.gen.nz>
 160
 161         * boot-9.scm (scm-error): deleted, reimplemented in C.
 162
 163 Mon Mar 10 15:48:31 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 164
 165         * boot-9.scm (process-define-module): Modified to handle both
 166         keywords and symbols.
 167
 168 Sat Mar  8 04:32:44 1997  Gary Houston  <ghouston@actrix.gen.nz>
 169
 170         * slib.scm: update read usage.
 171
 172         * r4rs.scm: update primitive-load usage.
 173         Don't define read-sharp.
 174
 175         * boot-9.scm: use read-hash-extend to install extra read syntax.
 176         (read-sharp): removed.
 177         Adjust usage of primitive-load-path, read, which no longer take
 178         case_i or read-sharp arguments.
 179
 180 Sat Mar  8 00:07:54 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 181
 182         * boot-9.scm: Added loading of session support module.
 183
 184         * debug.scm: Removed `display-application'.  (Replaced by
 185         primitive procedure.)
 186
 187         * boot-9.scm (beautify-user-module!): Don't add the root module
 188         interface to the end of the use-list of the root module.
 189
 190 Thu Mar  6 07:26:34 1997  Gary Houston  <ghouston@actrix.gen.nz>
 191
 192         * boot-9.scm: repl-quit, repl-abort: obsolete variables deleted.
 193
 194 Wed Mar  5 20:30:24 1997  Gary Houston  <ghouston@actrix.gen.nz>
 195
 196         * boot-9.scm: check use-emacs-interface for emacs support.
 197
 198 Sun Mar  2 19:47:14 1997  Gary Houston  <ghouston@actrix.gen.nz>
 199
 200         * boot-9.scm (scm-style-repl): call repl-report-start-timing if
 201         read gets EOF.
 202         * (exit): alias for quit.
 203
 204 Sun Mar  2 05:25:11 1997  Gary Houston  <ghouston@actrix.gen.nz>
 205
 206         * boot-9.scm (error-catching-loop thunk): use a status variable to
 207         return the quit args.
 208         (scm-style-repl): call -quit, passing return value from
 209         error-catching-repl.  Make -quit return its args.
 210         stand-alone-repl: comment out, since it seems unused.
 211
 212         (error-catching-loop thunk): discard trailing junk after a (quit).
 213
 214 Sat Mar  1 15:24:39 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 215
 216         * boot-9.scm: Removed the old printer code.
 217
 218         * r4rs.scm (apply, call-with-current-continuation): Added comment
 219         explaining why apply and call/cc need to be closures.
 220
 221         * boot-9.scm (apply, call-with-current-continuation): Bugfix:
 222         Removed. These definitions are already present in r4rs.scm.
 223
 224         * debug.scm (trace-entry, trace-exit): Check that we're on a repl
 225         stack before printing traced frames; Re-enable trace flag at end
 226         of handlers.
 227
 228 Sat Mar  1 00:10:38 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 229
 230         * debug.scm: Add hook for reset of trace level at abort.
 231
 232         * boot-9.scm (run-hooks): New procedure.
 233         (add-hooks!): New macro.
 234         Change hooks to use these functions.
 235
 236         * debug.scm: *Warning* This feature is a bit premature.  I add
 237         it anyway because 1. it is very useful, and, 2. you can start
 238         making it less premature by complaining to me and by modifying
 239         the source! :-)
 240         (trace): Given one or more procedure objects, trace each one.
 241         Given no arguments, show all traced procedures.
 242         (untrace): Given one or more procedure objects, untrace each one.
 243         Given no arguments, untrace all traced procedures.  The tracing in
 244         Guile have an advantage to most other systems: We don't create new
 245         procedure objects, but mark the procedure objects themselves.
 246         This means that also anonymous and internal procedures can be
 247         traced.
 248
 249         * boot-9.scm (error-catching-loop): Added handling of apply-frame
 250         and exit-frame exceptions.
 251
 252         * boot-9.scm (assert-repl-prompt, the-prompt-string): Removed.
 253         (set-repl-prompt!): Setter for repl prompt.
 254         (scm-style-repl): If prompt is #f, don't prompt; if prompt is a
 255         string, display it; if prompt is a thunk, call it and display its
 256         result; otherwise display "> ".
 257         (Change suggested by Roland Orre <orre@nada.kth.se>.)
 258
 259         * r4rs.scm (%load-verbosely): Reverted change to
 260         `module-defined?', since the module system isn't bootstrapped when
 261         we load r4rs.scm.  This is just a temporary fix to make the
 262         repository version runnable.
 263
 264 Thu Feb 27 23:25:47 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 265
 266         * boot-9.scm: Removed the enabling of debug evaluator and
 267         recording of source code positions.  This was placed there for our
 268         convenience, but it has already sneaked into the distribution
 269         once... so we'd better add this in our local copies instead when
 270         we need it.  (These options are normally enabled at the end of
 271         boot-9.scm when loading the debug module.)
 272
 273 Thu Feb 27 16:04:45 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 274
 275         * boot-9.scm (module-defined?): New function.
 276         (macroexpand-1, macroexpand): Use local-ref instead of defined?
 277         and eval.
 278         * r4rs.scm (%load-verbosely): Use "module-defined?" instead of
 279         "defined?".
 280         * slib.scm (defined?): New function to take the place of the
 281         builtin "defined?".  It allways examines the slib module.
 282
 283 Mon Feb 24 21:46:15 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 284
 285         * configure.in: Added AM_MAINTAINER_MODE
 286
 287 Sat Feb 15 04:51:20 1997  Gary Houston  <ghouston@actrix.gen.nz>
 288
 289         * boot-9.scm (read-sharp): define directly, don't go through a
 290         %read-sharp layer.
 291
 292 Tue Feb 11 08:45:48 1997  Gary Houston  <ghouston@actrix.gen.nz>
 293
 294         * boot-9.scm (uniform-vector-set!): use uniform-array-set1!, not
 295         uniform-vector-set1! which doesn't exist.
 296
 297 Mon Feb 10 03:01:48 1997  Mikael Djurfeldt  <mdj@kenneth>
 298
 299         * boot-9.scm (backtrace): Removed.  (A C version now exists in
 300         backtrace.c.)
 301
 302 Fri Jan 24 06:05:36 1997  Gary Houston  <ghouston@actrix.gen.nz>
 303
 304         * boot-9.scm (read-line!, read-delimited!, read-delimited,
 305         read-line): new procedures, see libguile/ChangeLog.
 306
 307 Thu Jan 16 17:07:03 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 308
 309         Added dynamic linking of modules. See libguile/DYNAMIC-LINKING.
 310
 311         * boot-9.scm (split-c-module-name, convert-c-registered-modules,
 312         init-dynamic-module, dynamic-maybe-call,
 313         find-and-link-dynamic-module, link-dynamic-module,
 314         try-module-dynamic-link, registered-modules): New definitions for
 315         dynamic linking of modules.
 316         (resolve-module): Try to dynamically link the requested module
 317         after failing to load it as Scheme code.
 318
 319 Wed Jan  8 05:50:14 1997  Gary Houston  <ghouston@actrix.gen.nz>
 320
 321         * boot-9.scm (getservbyport, getservbyname): remove stray %.
 322
 323 Tue Jan  7 20:02:24 1997  Jim Blandy  <jimb@floss.cyclic.com>
 324
 325         * boot-9.scm (and=>): Rename THUNK argument to PROCEDURE, 'cos
 326         that's what it is.
 327
 328         * lineio.scm (make-line-buffering-input-port): Properly test for
 329         the case of an empty buffer list.  The old code assumed that '()
 330         was false.
 331
 332 Mon Jan  6 01:13:53 1997  Mikael Djurfeldt  <mdj@kenneth>
 333
 334         * boot-9.scm (use-modules): New macro (from Marius Vollmer).
 335         (use-modules <module name> ...) Put the the modules named by
 336         <module name> ... on the use list of the current module.
 337
 338 Sun Jan  5 15:52:59 1997  Jim Blandy  <jimb@floss.cyclic.com>
 339
 340         * boot-9.scm (error-catching-loop): Remove message saying that
 341         typing "$" will put you in the debugger.  This isn't implemented
 342         yet.
 343
 344 Sun Dec 22 23:27:25 1996  Jim Blandy  <jimb@floss.cyclic.com>
 345
 346         * boot-9.scm (delq-all!): Function deleted; delq!'s semantics have
 347         been fixed, so this function is superfluous.
 348         (transform-usage-lambda): Use delq!, not delq-all!.
 349
 350 Tue Dec 17 20:36:45 1996  Marius Vollmer  <mvo@zagadka.ping.de>
 351
 352         * boot-9.scm (resolve-module): New optional parameter that
 353         controls whether autoloading is attempted or not. Default is #t.
 354         (process-define-module): Don't autoload the defined module.
 355         (try-module-autoload): Don't autoload the directory modules.
 356
 357         * boot-9.scm (process-define-module): Ensure that the-scm-module
 358         is last in the `uses' list to allow shadowing builtin
 359         bindings. All :use-module options are added in the order they
 360         appear in the arguments but before anything already on the list
 361         (such as the-scm-module).

 363 Wed Dec 11 21:06:05 1996  Gary Houston  <ghouston@actrix.gen.nz>
 364
 365         * slib.scm (slib-parent-dir): throw error if #f returned from
 366         %search-load-path.
 367
 368 Sat Nov 30 23:57:28 1996  Tom Tromey  <tromey@cygnus.com>
 369
 370         * PLUGIN/greet, PLUGIN/split.sed, PLUGIN/this.configure: Removed.
 371         * Makefile.am, aclocal.m4: New files.
 372         * configure.in: Updated for Automake.
 373
 374 Wed Nov 27 14:16:14 1996  Marius Vollmer  <mvo@zagadka.ping.de>
 375
 376         * boot-9.scm (macroexpand-1, macroexpand), slib.scm
 377         (slib:features), r4rs.scm (%load-verbosely): "defined?" is now a
 378         function, use it accordingly.
 379
 380 Thu Nov 21 11:12:10 1996  Jim Blandy  <jimb@floss.cyclic.com>
 381
 382         It's an "eval closure", not an "eval thunk."  A thunk is a
 383         function of no arguments.
 384         * boot-9.scm (module-type): Rename module field.
 385         (make-module, eval-in-module, make-root-module,
 386         set-current-module): Uses changed.
 387         (module-eval-closure, set-module-eval-closure!,
 388         root-module-closure): Renamed from module-eval-thunk,
 389         set-module-eval-thunk!, root-module-thunk.
 390         (set-current-module): Change uses of *top-level-lookup-thunk* to
 391         *top-level-eval-closure*.
 392
 393 Wed Nov 20 14:45:27 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 394
 395         * slib.scm (slib-parent-dir): Use string-length, not length.
 396         (Thanks to Bernard Urban.)
 397
 398 Sat Nov  2 20:00:42 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 399
 400         * boot-9.scm: The debugging evaluator and recording of positions
 401         aren't enabled by default any longer (they are switched on in
 402         debug.scm).  But during development we want to have them also
 403         *inside* boot-9.scm.  Therefore, two lines are added at the
 404         beginning of boot-9.scm to enable these.
 405
 406         Call `provide' so that `records' are included among the
 407         `*features*'.
 408
 409         The scheme for saving the stack has been adjusted: save-stack is
 410         now commonly available for saving the stack.  Calling `save-stack'
 411         sets a flag `stack-saved?' which prevents overwriting the stack.
 412         `stack-saved?' is reset at `abort'.
 413
 414         Spelling correction: seperate --> separate.
 415
 416         Removed `:'s that had creeped into some comments.
 417
 418         The repl now doesn't print #<unspecified> results any longer
 419         If the user wants to see this, he can do
 420         (assert-repl-print-unspecified #t) in his startup file.
 421
 422         The user now gets a friendly message instead of a backtrace at
 423         error.
 424
 425         Added `before-read-hook'.
 426
 427         Load module (ice-9 emacs) if option `-e' was specified.
 428
 429         (provide): New function.
 430
 431         (error): Save stack at entry, so that Guile entrails won't show up
 432         in backtraces.
 433
 434         (backtrace): New function.
 435
 436         (save-stack): Can now take arbitrary number of stack narrowing
 437         specifier pairs.  The first specifier in a pair controls inner
 438         border, the second the outer border.  A number means cut that
 439         number of frames, a procedure object means cut until that object
 440         is found in operator position in a frame.
 441
 442         * debug.scm: Enable debugging evaluator and recording of positions
 443         by default.
 444
 445         * slib.scm (slib:load): Adapt to the new behavior of
 446         primitive-load: It doesn't any longer try both with and without
 447         ".scm" extension.  (We don't want to use %search-load-path here.)
 448
 449         (implementation-vicinity): New function.  slib requires it
 450
 451         (library-vicinity): Updated.
 452
 453         Load "require.scm" in the library-vicinity.
 454
 455         (install-require-vicinity, install-require-module): New functions.
 456
 457 Mon Oct 28 17:56:29 1996  Jim Blandy  <jimb@floss.cyclic.com>
 458
 459         * boot-9.scm (load-from-path): New function.
 460
 461         * boot-9.scm (try-load, basic-try-load, try-load-module,
 462         try-load): Deleted.  I don't think they're being used.
 463
 464         * Makefile.in (scm_files): Add r4rs.scm and test.scm to this list,
 465         so they'll get distributed.
 466
 467         Get Guile to be a little less chatty by default.  The new user
 468         should see as little clutter as possible.
 469         * r4rs.scm (%load-verbosely): Make this #f by default.
 470         * boot-9.scm (scm-repl-verbose): Make this #f by default.
 471         (scm-style-repl): Don't run 'pk' on the value passed to quit.
 472
 473         * r4rs.scm: New file.
 474         * boot-9.scm: Load r4rs.scm, first thing.
 475         (OPEN_READ, OPEN_WRITE, OPEN_BOTH, *null-device*, open-input-file,
 476         open-output-file, open-io-file, close-input-port,
 477         close-output-port, close-io-port, call-with-input-file,
 478         call-with-output-file, with-input-from-port, with-output-to-port,
 479         with-error-to-port, with-input-from-file, with-output-to-file,
 480         with-error-to-file, with-input-from-string, with-output-to-string,
 481         with-error-to-string, the-eof-object): Definitions moved to
 482         r4rs.scm.  Not all of them are R4RS, but those that are use those
 483         that are not.
 484         (load, %load-verbosely, %load-announce): Moved, along with code to
 485         set %load-hook, to r4rs.scm.
 486
 487         * test.scm: New file.
 488
 489         * boot-9.scm (integer?): Definition deleted, in favor of the one
 490         present in libguile (which used to be called int?).  I have no
 491         idea why integer? didn't just call int? to begin with.
 492
 493         * boot-9.scm (<, <=, =, >, >=): Definitions in terms of <?, <=?,
 494         =?, >?, and >=? deleted; they're defined that way by libguile now.
 495
 496         * boot-9.scm (load): Simplified; primitive-load does most of this
 497         work now.
 498         (%load-announce-win): Removed; no longer used.  Set %load-hook to
 499         call %load-announce.
 500
 501 Sun Oct 27 07:47:03 1996  Gary Houston  <ghouston@actrix.gen.nz>
 502
 503         * boot-9.scm (stat:dev, stat:ino, stat:mode, stat:nlink, stat:uid,
 504         stat:gid, stat:rdev, stat:size, stat:atime, stat:mtime,
 505         stat:ctime, stat:blksize, stat:blocks) accessor functions for stat
 506         components.
 507         (file-is-directory?): use stat:type.
 508
 509 Fri Oct 25 03:34:47 1996  Jim Blandy  <jimb@floss.cyclic.com>
 510
 511         * boot-9.scm (%read-sharp): Don't recognize the `#!' syntax here;
 512         that's now taken care of in libguile, and in a way compatible with
 513         SCSH (which this isn't).
 514
 515 Mon Oct 21 18:52:36 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 516
 517         * boot-9.scm: Formatting tweaks.
 518
 519 Fri Oct 18 01:03:08 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 520
 521         * boot-9.scm (handle-system-error): Added hooks before-error-hook,
 522         after-error-hook, before-backtrace-hook and after-backtrace-hook
 523         to the error handler.  E.g.: fancy emacs support could plug into
 524         these.
 525         (save-stack): New function.  The stack is now made differently
 526         depending on the stack id.  (The motivation is to make a better
 527         choice regarding what stack frames to present to the user.)
 528         (error-catching-loop): Stack handling code moved outside into
 529         save-stack.
 530
 531 Thu Oct 17 20:33:08 1996  Gary Houston  <ghouston@actrix.gen.nz>
 532
 533         * Makefile.in (scm_files): add expect.scm.
 534
 535         * expect.scm: new file ported from guile-iii.
 536
 537         * boot-9.scm: remove handle-system-error, after moving the code into
 538         error-catching-loop.
 539         Don't set 'throw-handler-default property on error keys.
 540         Just interpret (almost) any throw with 4 args as an error throw.
 541         Delete some try-load stuff that was already commented out.
 542
 543         Second thoughts, keep handle-system-error but call it from
 544         error-catching-loop.
 545
 546 Tue Oct 15 17:07:20 1996  Jim Blandy  <jimb@floss.cyclic.com>
 547
 548         * boot-9.scm: Doc fixes.
 549         (make-module): Rework for readability.
 550         (make-root-module, make-scm-module): USES argument to make-module
 551         should be '(), not #f.
 552
 553         * boot-9.scm (try-load): %sys-load-path has been renamed to
 554         primitive-load-path; adjust call here.
 555
 556 Tue Oct 15 14:25:01 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 557
 558         * boot-9.scm (signal-handler): Bugfix: Moved the recording of
 559         the stack to the correct place: when it is decided to generate an
 560         error-signal.
 561
 562 Mon Oct 14 22:20:30 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 563
 564         * boot-9.scm (error-catching-loop, signal-handler,
 565         handle-system-error): Backtracing now works for signals aswell;
 566         Backtracing mechanism can now identify the stack root created by
 567         start-stack so that the user isn't exposed to system stack frames.
 568
 569 Mon Oct 14 06:05:42 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 570
 571         * Makefile.in: Added threads.scm.
 572
 573 Mon Oct 14 04:21:51 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 574
 575         * debug.scm (make-enable, make-disable): Simplified.
 576
 577         * boot-9.scm: Renamed %%throw-handler-default -->
 578         throw-handler-default.
 579         ((handle-system-error key . arg-list)): Changed the way errors are
 580         reported.
 581         ((scm-style-repl)): Wrap up the call to eval in a start-stack
 582         acro.
 583         ((error-catching-loop thunk)): Introduce a lazy-catch into
 584         error-catching-loop so that the stack can be captured.
 585
 586 Thu Oct 10 22:27:32 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 587
 588         * mapping.scm (hash-table-mapping): Explicitly request that
 589         make-vector fill new vectors with '(); this will make it easier to
 590         port Guile Scheme code to other Schemes.
 591         * boot-9.scm (make-print-style, make-print-table): Same.
 592
 593 Sun Oct  6 03:54:59 1996  Gary Houston  <ghouston@actrix.gen.nz>
 594
 595         * boot-9.scm (load): rewritten again.
 596         Append "." to the default %load-path.
 597         (feature?): new function: checks for a symbol in the features list.
 598         (module-local-variable): remove apparently useless (caddr (list m v
 599         ...))
 600         (%load-announce): minor formatting change.
 601         (file-exists?): use access? if posix is featured.
 602         (file-is-directory?): use stat if i/o-extensions is featured.
 603         (try-module-autoload module-name): use file-exists? before
 604         file-is-directory?
 605
 606 Sat Oct  5 18:54:03 1996  Mikael Djurfeldt  <mdj@kenneth>
 607
 608         * boot-9.scm: Added conditional loading of threads.scm.
 609
 610         * threads.scm: New file.  Modified from the Cygnus-r0.3
 611         distribution.
 612
 613         * boot-9.scm (error-catching-loop): Added handling of key
 614         `switch-repl'.
 615
 616         * boot-9.scm: Name change %%bad-throw --> bad-throw.
 617
 618 Wed Oct  2 23:38:44 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 619
 620         * boot-9.scm (make-record-type, record-constructor): Don't assume
 621         the empty list is false when parsing the argument list.
 622
 623 Mon Sep 30 22:15:50 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 624
 625         * boot-9.scm (signal-handler): Clean up logic.
 626
 627         * boot-9.scm (load): Assume %load-path is always bound.
 628
 629 Sat Sep 28 00:15:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
 630
 631         * boot-9.scm (error): replace another throw with scm-error.  Throw
 632         to 'misc-error instead of 'error (no need to distinguish these.)
 633         Don't set up 'error as a key.
 634         Set up regex-error as a key, if regex is available.
 635         (signal-handler): use scm-error, not throw.
 636
 637         (%try-load, try-load-with-path, %load, load-with-path,
 638         basic-try-load-with-path, basic-load-with-path,
 639         try-load-module-with-path,load-module-with-path): deleted, since
 640         they seem redundant.
 641         (try-load): define using %try-load, not try-load-with-path.
 642         (load): rewritten.  load tries to open the file directly and
 643         with a .scm extension before searching the library directories
 644         (should "." be added to %load-path?  then load could still open
 645         directly files starting with "/").
 646         (try-module-autoload): use load, not load-with-path.
 647         (%load-indent): deleted, -2 was causing errors.
 648
 649         (%read-sharp): use port-line, not line-number.
 650
 651 Fri Sep 27 16:23:51 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 652
 653         * boot-9.scm (%%bad-throw): Delete definition. 1) It's very
 654         straightforward to provide the equivalent functionality using
 655         (catch #t ...), so there's no need for the extra complexity.  2)
 656         Outside the context of a read-eval-print loop (which Guile should
 657         not require) it's not clear we should do anything more complicated
 658         than print an error and exit; the user or REPL can establish
 659         something better if it wants.  3) In that case, it's much more
 660         robust to just do it in the C code.
 661
 662 Tue Sep 24 06:53:04 1996  Gary Houston  <ghouston@actrix.gen.nz>
 663
 664         * boot-9.scm (%try-load): define using primitive-load.  Previously
 665         %try-load itself was the primitive.
 666         (load-with-path): use scm-error instead of %load-announce-lossage.
 667         Errors are thrown to 'misc-error instead of 'could-not-load.
 668         (%load-announce-lossage): deleted.
 669
 670 Mon Sep 23 00:16:31 1996  Mikael Djurfeldt  <mdj@kenneth>
 671
 672         * boot-9.scm (warn, scm-style-repl): Use C printer instead of `print'.
 673         (make-record-type type-name fields): Temporarily remove support
 674         for printing of records (not possible yet with C printer).
 675
 676 Fri Sep 20 00:24:27 1996  Gary Houston  <ghouston@actrix.gen.nz>
 677
 678         * boot-9.scm (file-exists?, file-is-directory): catch only
 679         system-error, not every kind of error.
 680         (scm-error): new procedure.
 681
 682 Thu Sep 19 16:02:46 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 683
 684         * boot-9.scm: Formatting tweaks.
 685
 686 Wed Sep 18 09:07:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
 687
 688         * boot-9.scm (%%handle-system-error key): remove the code for
 689         SCM-style errors.  handle the case that an unexpected number
 690         of args are supplied.
 691         (%%system-errors): removed.
 692         (error): redefine using a throw with key and 4 args.
 693         ('error): associate 'error, 'error-signal keys with
 694         %%handle-system-error.
 695         (%%default-error-handler): removed.
 696         (signal-handler): throw with 4 args and use the error-signal key.
 697         Create an error message instead of using numerical codes.
 698         (%%bad-throw): call error instead of throw if key not found.
 699
 700 Tue Sep 17 04:11:28 1996  Gary Houston  <ghouston@actrix.gen.nz>
 701
 702         * boot-9.scm: initialize new error keys (see libguile/ChangeLog).
 703         (%%handle-system-error key): check subr is not #f before printing.
 704         Recognize %s (embed an argument using "display") and
 705         %S (embed an argument using "write").
 706
 707 Sun Sep 15 03:55:35 1996  Gary Houston  <ghouston@actrix.gen.nz>
 708
 709         * boot-9.scm (%%handle-system-error key): set args and rest to
 710         the empty list if they are #f.
 711         Initialize out-of-range as an error key.
 712
 713 Sat Sep 14 03:41:15 1996  Gary Houston  <ghouston@actrix.gen.nz>
 714
 715         * PLUGIN/REQ: remove the "ice-9 lgh" line which causes a cycle.

 725
 726         * boot-9.scm: Name change: value-ref --> local-ref
 727         resolved-ref --> nested-ref  Motivation: conformance to the other
 728         dictionary operators: list-ref operates on list, vector-ref
 729         operates on vector, nested-ref operates on nested namespace,
 730         local-ref operates on the local nested namespace.

 763         Don't use the PLUGIN system to gather information for the

 767         for these.
