   1 Mon Oct 28 17:56:29 1996  Jim Blandy  <jimb@floss.cyclic.com>
   2
   3         * boot-9.scm (load): Simplified; primitive-load does most of this
   4         work now.
   5         (%load-announce-win): Removed; no longer used.  Set %load-hook to
   6         call %load-announce.
   7
   8 Sun Oct 27 07:47:03 1996  Gary Houston  <ghouston@actrix.gen.nz>
   9
  10         * boot-9.scm (stat:dev, stat:ino, stat:mode, stat:nlink, stat:uid,
  11         stat:gid, stat:rdev, stat:size, stat:atime, stat:mtime,
  12         stat:ctime, stat:blksize, stat:blocks) accessor functions for stat
  13         components.
  14         (file-is-directory?): use stat:type.
  15
  16 Fri Oct 25 03:34:47 1996  Jim Blandy  <jimb@floss.cyclic.com>
  17
  18         * boot-9.scm (%read-sharp): Don't recognize the `#!' syntax here;
  19         that's now taken care of in libguile, and in a way compatible with
  20         SCSH (which this isn't).
  21
  22 Mon Oct 21 18:52:36 1996  Jim Blandy  <jimb@totoro.cyclic.com>
  23
  24         * boot-9.scm: Formatting tweaks.
  25
  26 Fri Oct 18 01:03:08 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
  27
  28         * boot-9.scm (handle-system-error): Added hooks before-error-hook,
  29         after-error-hook, before-backtrace-hook and after-backtrace-hook
  30         to the error handler.  E.g.: fancy emacs support could plug into
  31         these.
  32         (save-stack): New function.  The stack is now made differently
  33         depending on the stack id.  (The motivation is to make a better
  34         choice regarding what stack frames to present to the user.)
  35         (error-catching-loop): Stack handling code moved outside into
  36         save-stack.
  37
  38 Thu Oct 17 20:33:08 1996  Gary Houston  <ghouston@actrix.gen.nz>
  39
  40         * Makefile.in (scm_files): add expect.scm.
  41
  42         * expect.scm: new file ported from guile-iii.
  43
  44         * boot-9.scm: remove handle-system-error, after moving the code into
  45         error-catching-loop.
  46         Don't set 'throw-handler-default property on error keys.
  47         Just interpret (almost) any throw with 4 args as an error throw.
  48         Delete some try-load stuff that was already commented out.
  49
  50         Second thoughts, keep handle-system-error but call it from
  51         error-catching-loop.
  52
  53 Tue Oct 15 17:07:20 1996  Jim Blandy  <jimb@floss.cyclic.com>
  54
  55         * boot-9.scm: Doc fixes.
  56         (make-module): Rework for readability.
  57         (make-root-module, make-scm-module): USES argument to make-module
  58         should be '(), not #f.
  59
  60         * boot-9.scm (try-load): %sys-load-path has been renamed to
  61         primitive-load-path; adjust call here.
  62
  63 Tue Oct 15 14:25:01 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
  64
  65         * boot-9.scm (signal-handler): Bugfix: Moved the recording of
  66         the stack to the correct place: when it is decided to generate an
  67         error-signal.
  68
  69 Mon Oct 14 22:20:30 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
  70
  71         * boot-9.scm (error-catching-loop, signal-handler,
  72         handle-system-error): Backtracing now works for signals aswell;
  73         Backtracing mechanism can now identify the stack root created by
  74         start-stack so that the user isn't exposed to system stack frames.
  75
  76 Mon Oct 14 06:05:42 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
  77
  78         * Makefile.in: Added threads.scm.
  79
  80 Mon Oct 14 04:21:51 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
  81
  82         * debug.scm (make-enable, make-disable): Simplified.
  83
  84         * boot-9.scm: Renamed %%throw-handler-default -->
  85         throw-handler-default.
  86         ((handle-system-error key . arg-list)): Changed the way errors are
  87         reported.
  88         ((scm-style-repl)): Wrap up the call to eval in a start-stack
  89         acro.
  90         ((error-catching-loop thunk)): Introduce a lazy-catch into
  91         error-catching-loop so that the stack can be captured.
  92
  93 Thu Oct 10 22:27:32 1996  Jim Blandy  <jimb@totoro.cyclic.com>
  94
  95         * mapping.scm (hash-table-mapping): Explicitly request that
  96         make-vector fill new vectors with '(); this will make it easier to
  97         port Guile Scheme code to other Schemes.
  98         * boot-9.scm (make-print-style, make-print-table): Same.
  99
 100 Sun Oct  6 03:54:59 1996  Gary Houston  <ghouston@actrix.gen.nz>
 101
 102         * boot-9.scm (load): rewritten again.
 103         Append "." to the default %load-path.
 104         (feature?): new function: checks for a symbol in the features list.
 105         (module-local-variable): remove apparently useless (caddr (list m v
 106         ...))
 107         (%load-announce): minor formatting change.
 108         (file-exists?): use access? if posix is featured.
 109         (file-is-directory?): use stat if i/o-extensions is featured.
 110         (try-module-autoload module-name): use file-exists? before
 111         file-is-directory?
 112
 113 Sat Oct  5 18:54:03 1996  Mikael Djurfeldt  <mdj@kenneth>
 114
 115         * boot-9.scm: Added conditional loading of threads.scm.
 116
 117         * threads.scm: New file.  Modified from the Cygnus-r0.3
 118         distribution.
 119
 120         * boot-9.scm (error-catching-loop): Added handling of key
 121         `switch-repl'.
 122
 123         * boot-9.scm: Name change %%bad-throw --> bad-throw.
 124
 125 Wed Oct  2 23:38:44 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 126
 127         * boot-9.scm (make-record-type, record-constructor): Don't assume
 128         the empty list is false when parsing the argument list.
 129
 130 Mon Sep 30 22:15:50 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 131
 132         * boot-9.scm (signal-handler): Clean up logic.
 133
 134         * boot-9.scm (load): Assume %load-path is always bound.
 135
 136 Sat Sep 28 00:15:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
 137
 138         * boot-9.scm (error): replace another throw with scm-error.  Throw
 139         to 'misc-error instead of 'error (no need to distinguish these.)
 140         Don't set up 'error as a key.
 141         Set up regex-error as a key, if regex is available.
 142         (signal-handler): use scm-error, not throw.
 143
 144 *       (%try-load, try-load-with-path, %load, load-with-path,
 145         basic-try-load-with-path, basic-load-with-path,
 146         try-load-module-with-path,load-module-with-path): deleted, since
 147         they seem redundant.
 148         (try-load): define using %try-load, not try-load-with-path.
 149 *       (load): rewritten.  load tries to open the file directly and
 150         with a .scm extension before searching the library directories
 151         (should "." be added to %load-path?  then load could still open
 152         directly files starting with "/").
 153         (try-module-autoload): use load, not load-with-path.
 154         (%load-indent): deleted, -2 was causing errors.
 155
 156         (%read-sharp): use port-line, not line-number.
 157
 158 Fri Sep 27 16:23:51 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 159
 160         * boot-9.scm (%%bad-throw): Delete definition. 1) It's very
 161         straightforward to provide the equivalent functionality using
 162         (catch #t ...), so there's no need for the extra complexity.  2)
 163         Outside the context of a read-eval-print loop (which Guile should
 164         not require) it's not clear we should do anything more complicated
 165         than print an error and exit; the user or REPL can establish
 166         something better if it wants.  3) In that case, it's much more
 167         robust to just do it in the C code.
 168
 169 Tue Sep 24 06:53:04 1996  Gary Houston  <ghouston@actrix.gen.nz>
 170
 171         * boot-9.scm (%try-load): define using primitive-load.  Previously
 172         %try-load itself was the primitive.
 173         (load-with-path): use scm-error instead of %load-announce-lossage.
 174         Errors are thrown to 'misc-error instead of 'could-not-load.
 175         (%load-announce-lossage): deleted.
 176
 177 Mon Sep 23 00:16:31 1996  Mikael Djurfeldt  <mdj@kenneth>
 178
 179         * boot-9.scm (warn, scm-style-repl): Use C printer instead of `print'.
 180         (make-record-type type-name fields): Temporarily remove support
 181         for printing of records (not possible yet with C printer).
 182
 183 Fri Sep 20 00:24:27 1996  Gary Houston  <ghouston@actrix.gen.nz>
 184
 185         * boot-9.scm (file-exists?, file-is-directory): catch only
 186         system-error, not every kind of error.
 187         (scm-error): new procedure.
 188
 189 Thu Sep 19 16:02:46 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 190
 191         * boot-9.scm: Formatting tweaks.
 192
 193 Wed Sep 18 09:07:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
 194
 195         * boot-9.scm (%%handle-system-error key): remove the code for
 196         SCM-style errors.  handle the case that an unexpected number
 197         of args are supplied.
 198         (%%system-errors): removed.
 199         (error): redefine using a throw with key and 4 args.
 200         ('error): associate 'error, 'error-signal keys with
 201         %%handle-system-error.
 202         (%%default-error-handler): removed.
 203         (signal-handler): throw with 4 args and use the error-signal key.
 204         Create an error message instead of using numerical codes.
 205         (%%bad-throw): call error instead of throw if key not found.
 206
 207 Tue Sep 17 04:11:28 1996  Gary Houston  <ghouston@actrix.gen.nz>
 208
 209         * boot-9.scm: initialize new error keys (see libguile/ChangeLog).
 210         (%%handle-system-error key): check subr is not #f before printing.
 211         Recognize %s (embed an argument using "display") and
 212         %S (embed an argument using "write").
 213
 214 Sun Sep 15 03:55:35 1996  Gary Houston  <ghouston@actrix.gen.nz>
 215
 216         * boot-9.scm (%%handle-system-error key): set args and rest to
 217         the empty list if they are #f.
 218         Initialize out-of-range as an error key.
 219
 220 Sat Sep 14 03:41:15 1996  Gary Houston  <ghouston@actrix.gen.nz>
 221
 222         * PLUGIN/REQ: remove the "ice-9 lgh" line which causes a cycle.
 223
 224         * boot-9.scm: remove leading %% from references to '%%system-error.
 225         (%%handle-system-error): don't pass all the thrown arguments when
 226         aborting, just the key and subr.
 227         Remove the code to "Install default handlers for built-in errors."
 228         Remove the definition of the syserror procedure.
 229         Associate 'numerical-overflow with default handler.
 230
 231 Fri Sep 13 04:58:11 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 232
 233         * boot-9.scm: Name change: value-ref --> local-ref
 234         resolved-ref --> nested-ref  Motivation: conformance to the other
 235         dictionary operators: list-ref operates on list, vector-ref
 236         operates on vector, nested-ref operates on nested namespace,
 237         local-ref operates on the local nested namespace.
 238
 239 Sat Sep  7 06:44:47 1996  Gary Houston  <ghouston@actrix.gen.nz>
 240
 241         * boot-9.scm (%%handle-system-error): recognise errors thrown
 242         by lgh-error (fill-message etc.)
 243         (fill-message): check first whether args is null.
 244         (fill-message): bug fix and check that args is a list.
 245
 246 Thu Sep  5 11:33:41 1996  Jim Blandy  <jimb@floss.cyclic.com>
 247
 248         * boot-9.scm: %load-path is initialized in C code now.
 249         (implementation-vicinity, parse-path): Deleted, along with code to
 250         initialize %load-path.
 251
 252         * boot-9.scm (in-vicinity): If the vicinity doesn't end with a
 253         "/", use one to separate it from the file.
 254
 255 Thu Aug 29 23:05:11 1996  Thomas Morgan  <tmorgan@gnu.ai.mit.edu>
 256
 257         * boot-9.scm (%load-path): Add the site directory.
 258         Add the directory named after the version number.
 259         Prepend the version number to the other directories in the path.
 260         Simplify by mapping the common prefix onto each item.
 261         * Makefile.in (datadir, pkgdatadir, pkgverdatadir, subpkgdatadir,
 262         sitedatadir): New definitions.
 263         (libparent, libdir, install_path): Replaced by above.
 264         (install): Create the above directories.
 265         Put the source files into subpkgdatadir.
 266         (uninstall): Remove the above directories.
 267
 268 Thu Aug 29 21:48:47 1996  Jim Blandy  <jimb@floss.cyclic.com>
 269
 270         Don't use the PLUGIN system to gather information for the
 271         Makefile's distribution and installation targets; just put it all
 272         in the Makefile directly.
 273         * PLUGIN/this.configure (scm_files, aux_files): Remove sections
 274         for these.
 275         * configure.in: Remove code that gets and substitutes scm_files and
 276         aux_files.
 277         * Makefile.in (scm_files, aux_files): Write out the list of files
 278         here, where people expect to find them.
 279
 280 Fri Aug 23 06:44:36 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 281
 282         * boot-9.scm: Preliminary solution: optionally load the debug
 283         module.  Changed "gls" to "guile1.0b3".
 284
 285         * debug.scm: New file: debug extensions.
 286
 287 Wed Aug 21 13:06:56 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 288
 289         * boot-9.scm (print-vector): Renamed weak-hash-table? -->
 290         weak-key-hash-table?.  (Again!)
 291
 292 Tue Aug 20 07:31:39 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 293
 294         * boot-9.scm (print-vector, macro-table, xformer-table):
 295         Renamed weak-hash-table --> weak-key-hash-table.
 296
 297         * poe.scm (funcq-memo): Renamed weak-hash-table -->
 298         weak-key-hash-table.
 299
 300 Sat Aug  3 06:16:35 1996  Gary Houston  <ghouston@actrix.gen.nz>
 301
 302         * boot-9.scm (*null-device*): global constant from goonix.
 303         (move->fdes): adjusted for boolean primitive-move->fdes.  return
 304         the modified port, always set revealed count to 1 (SCSH compatible).
 305         (release-port-handle port): from goonix (SCSH compatible).
 306         (%open-file): removed.
 307         (open-input-file, open-output-file, file-exists?, file-is-directory?):
 308         modified for open-file change (does not return #f).
 309
 310 Thu Aug  1 02:52:42 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 311
 312         * Makefile.in (dist-dir): New target for new dist system.
 313         (manifest): Deleted.
 314         * PLUGIN/this.configure (aux_files): Removed PLUGIN; it's a
 315         directory, and needs special treatment in the dist-dir target.
 316
 317 Thu Aug  1 09:00:21 1996  Gary Houston  <ghouston@actrix.gen.nz>
 318
 319         * boot-9.scm: remove the wrappers for '%' system primitives,
 320         now that they throw errors directly.
 321         remove make-simple-wrapper and similar functions.
 322         protect a call to getenv which may now throw an exception.
 323
 324 Wed Jul 31 23:44:42 1996  Gary Houston  <ghouston@actrix.gen.nz>
 325
 326         * boot-9.scm (false-if-exception): new macro.
 327
 328 Fri Apr 19 13:53:08 1996  Tom Lord  <lord@beehive>
 329
 330         * The more things change...
 331
 332
