Mon Mar 8 06:11:40 2004 UTC (10 years, 1 month ago) by kaz
Branch: MAIN
Changes since 1.187: +2 -1 lines
Revamped loading system. Got rid of require/provide in all
Lisp source files.

* code/mcvs.lisp: New file. Responsible for compiling and loading
everything in the right order.

* code/mcvs-main.lisp: File renamed to main.lisp.

* code/mcvs-package.lisp: File renamed to package.lisp.

* code/system.lisp: File removed.
1 Release for Meta-CVS
3 Release ?.??, 200?-??-??:
5 All Lisp symbols are in a package. Compiling and loading is simplified,
6 and more portable.
8 Release 1.0.13, 2004-02-??:
10 The ``mcvs convert'' command now creates the TYPES and .cvsignore files.
12 Release 1.0.12, 2004-01-31:
14 Fixes various bugs in ``mcvs convert'', so that it is
15 actually useable now, albeit still far from a perfect CVS
16 migration tool.
18 The remap command can now purge the MAP of entries that refer to non-existent
19 F- files, which is useful for cleaning up after the convert algorithm,
20 if necessary.
22 Release 1.0.11, 2004-01-28:
24 Fixes breakage of list-branches command introduced in last release.
26 Fixes failures in grab command when pulling new baseline over
27 partial sandbox. Renamed symlinks, and execute permissions of files
28 were being accessed using abstract instead of real path.
30 Release 1.0.10, 2004-01-09:
32 Builds on CLISP 2.32. The lb command no longer produces bogus warning
33 when working copy is sticky to a version tag.
35 Release 1.0.9, 2003-11-24:
37 Failures to open terminal for reasons other than non-existence
38 of the object are handled (e.g. ``no such device'', etc).
40 The --nometa option now works properly in those commands that
41 operate on the whole project when no file arguments are given
42 (tag, update, commit). Also, these commands no longer implicitly
43 include the meta files when file arguments *are* given.
44 These files can be included explicitly with the --meta global option.
46 Release 1.0.8, 2003-06-03:
48 The Cygwin /dev/tty problem is partially addressed. The program
49 won't fail if /dev does not exist, but emits a warning message,
50 and disables interactive error handling. The workaround is to use
51 ``mkdir /dev''. This is a CLISP issue; its OPEN function expects the
52 full path to a file to actually exist, but on Cygwin, there are fake
53 /dev/* paths even though /dev does not exist. If a real /dev directory
54 does in fact exist, it does not interfere with these magic paths.
56 The ``mcvs fi'' command no longer performs expansion on F- names
57 that are preceded by a slash.
59 Release 1.0.7, 2003-04-23:
61 New commands sync-to-cvs and sync-from-cvs expose the hard link
62 synchronization algorithm.
64 Revamped error recovery logic. To continue in an error situation now
65 consistently means ``take the bold action that may erase data''
66 or ``proceed in the most obvious way to finish the specified job''.
67 It never means ``roll back the operation and bail'', which was
68 confusing.
70 Termination is no longer unsafe; the `T' menu command, and the
71 equivalent --error-terminate global option perform all necessary
72 restoration and cleanup.
74 Errors that have more information to print, like a list of files or
75 whatever, now indicate it in a standard way which translates to the
76 `I' menu command.
78 Chatter output goes to standard error rather than standard output,
79 as do all error messages.
81 The interactive error menu now talks to the user using the controlling
82 tty, meaning that it will work even if the input or output of the
83 mcvs command are redirected. If no controlling tty is available,
84 then interactive error handling is disabled; the default behavior
85 is then like --error-terminate but can of course be overridden by
86 --error-continue.
88 Release 1.0.6, 2003-04-14:
90 The create command detects the existence of text editor backup files (or
91 other junk) in the MCVS directory after the editor is invoked on the
92 TYPES file. The user is prompted regarding their removal. If these files are
93 not removed, cvs import will bring them into the repository.
95 When Meta-CVS has to split a large CVS command into two or more
96 invocations with shorter argument lists, it now does not stop when one of
97 these invocations is unsuccessful; it does all of them, and combines
98 their termination indications by a logical AND. There was a bug in this
99 logic also which caused, upon termination failure, a cvs command to be
100 repeated for the same list of files.
102 Synchronization logic has been revamped. Unnecessary synchronizations
103 have been removed, which will make some commands run faster.
104 Synchronizations now have specific directions; for instance before
105 a CVS commit or update, changes are pushed from the directory tree to the MCVS
106 directory only, and after the CVS operation, in the reverse direction only.
108 Meta-CVS will no longer re-create missing F- files by linking from the
109 directory tree. Doing this causes two problems. One is that if a user
110 manually removes a F- file and do ``mcvs up'', she wants CVS to fetch a clean
111 copy and push it into the tree. She does not want the file to be restored
112 from the tree prior to the CVS update. Secondly, sometimes CVS itself
113 removes files. If we re-create the files, CVS will consider them to
114 be ``in the way''.
116 Failures to read from the MAP or MAP-LOCAL files are treated as interactive,
117 continuable errors. By continuing, the user agrees that the behavior will
118 be as if an empty map were read.
120 The grab command uses less memory for performing move analysis.
122 Release 1.0.5, 2003-02-25:
124 Bugfix: some one-argument command line options of CVS must be
125 specifies as a single parameter, with no separation between the
126 option letter and the argument characters. For example:
128 cvs log -r rev-1::rev-2 # invalid
129 cvs log -rrev1::rev2 # correct
131 Meta-CVS accepts either syntax, but it was generating the first form
132 when calling CVS. Now, *all* one-letter options that have an argument
133 are formatted in the second manner.
135 Bugfix: one more waitpid() issue was fixed; on fast machines, under
136 Linux, it was observed that from time to time Meta-CVS would get
137 a -1/ECHILD when waiting for the CVS process.
139 Release 1.0.4, 2003-02-20:
141 Fix remaining occurences of the CVS ``No child processes'' abort
142 problem, affecting the list-branches command, merge command
143 and the -r option of the filt command.
145 Release 1.0.3, 2003-02-12:
147 ! THIS RELEASE IS WITHDRAWN. It was accidentally created from the
148 ! experimental main trunk of the Meta-CVS codebase, rather than
149 ! the 1.0 branch. But 1.0.4 does contain all of the changes
150 ! described here.
152 Fix for the CVS ``No child processes'' abort problem. It turns out
153 that CLISP sets the signal handling action for the SIGCHLD signal
154 to SIG_IGN, which is inherited by child processes across the
155 fork() and execvp() calls used in our mcvs_spawn() function.
156 We correct the problem by resetting the signal handler to SIG_DFL
157 just before executing the new process image.
159 New feature, --up option. The argument is a nonnegative integer value
160 (default is zero) which specifies how many sandbox nesting levels to
161 escape out of when locating the sandbox root. This helps work with
162 nested Meta-CVS sandboxes.
164 Release 1.0.2, 2003-02-10:
166 Bugfix in waitpid logic in the C library for running external processes;
167 we were not dealing with an interrupted waitpid.
169 Behavior of mcvs tag is changed: when there are no filename arguments,
170 the whole tree is tagged including the metafiles. In other words, it
171 now works like the commit command.
173 Release 1.0.1, 2003-01-30:
175 Hard link sync optimization: update of a subset of files, commit, and
176 other operations like log and diff don't need to synchronize all
177 hard links, just the ones operated on.
179 The merge and remerge commands support -k option for overriding
180 CVS keyword expansion mode.
182 Fixes to getcwd error handling.
184 Improvement in install.sh script's logic for locating CLISP installation
185 directory.
187 Release 1.0, 2003-01-01:
189 NOTE: It's not possible to upgrade to this release via mcvs-upgrade,
190 because it adds some new C functions to the Lisp executable.
192 Security fix: read-time evaluation was not suppressed when reading
193 structured data, like MCVS/MAP and MCVS/TYPES. This means that it
194 was possible for Alice to check in something that would execute
195 arbitrary code on Bob's computer.
197 Optimization: use fork and exec to launch CVS rather than CLISP's
198 run-program function, which indirects through the shell interpreter.
199 (On Cygwin, the spawnvp function is used).
201 Performance fix: stat() was being called superfluously by the
202 hard synchronization code, twice for each file.
204 Build fix: install.sh works when CLISP executable is called ``lisp.exe'',
205 which is the case under Cygwin with newer CLISP releases.
207 Release 0.99, 2002-11-17:
209 New link command for creating symbolic links.
211 Global option -n (dry run---don't modify filesystem) is processed
212 internally now, not just passed to CVS.
214 Failure to invoke text editor is handled.
216 The -r option of filt is fixed; it has been broken since the change to the
217 new MAP format, because it was reading the raw map representation, not
218 passing it through the right conversion steps that are needed now.
220 Bugfix to purge and remap commands: they were fooled by CVS-generated
221 files in the MCVS/CVS directory. Specifically, files having F- names, and a
222 the suffix ,t.
224 Bugfix to add logic in directory restructuring: there was the possibility
225 of mistakingly taking a clobbered local file to be a new local version of
226 the added file, instead of replacing it. This could happen if the local
227 file had a future timestamp relative to the one coming from the repository.
229 The prop command does not synchronize or write out map if no options are
230 specified.
232 Help text added for move and branch commands. Help text for grab rewritten.
234 The CVSEDITOR and VISUAL environment variables are now checked, not
235 only EDITOR.
237 Release 0.98, 2002-10-13:
239 The prop command was mistakenly reading from MAP-LOCAL and writing to MAP,
240 which could cause information loss if the two differ. It now reads from MAP
241 and writes to MAP. (The property changes propagate to MAP-LOCAL by the
242 update operation invoked by prop, as before).
244 Invocation of external programs included in debug trace.
246 The filt command does not filter F- names if they are immediately preceded by
247 the MCVS/ prefix; such occurences are clearly concrete, sandbox-relative
248 references to the actual F- links, rather than abstract references.
250 The update command now supports the -C option, to fetch the repository
251 copy, throwing away local changes. It also now honors the --metaonly
252 and --nometa options.
254 The export command has been added, for checking out documents without creating
255 a working copy (no MCVS directory in the root of the checkout).
257 The watch command has been added. Note that its syntax differs from that
258 of CVS.
260 The watchers, editors, edit, and unedit commands have been added.
262 A script called mcvs-upgrade is now included, and installs alongside the mcvs
263 script. This allows the Meta-CVS Lisp image to recompile and patch itself,
264 giving users of binary distributions an easy way to upgrade from source
265 code.
267 Release 0.97, 2002-10-06:
269 Meta-CVS now builds and runs on Microsoft Windows, under Cygwin
270 (www.cygwin.com). It still relies on hard links, which requires
271 Windows 2000 or XP, and the NTFS filesystem. It probably won't
272 work over FAT.
274 New --debug option for verbose output.
276 Cleaned up of error messages. Error messages don't specify prefixes like
277 ``mcvs-add:'' or ``mcvs-grab:'' any more. Rather, the error handler adds the
278 ``mcvs:'' prefix when printing the messages in a situation when the error is
279 not continuable.
281 Fixed bug introduced in release 0.13: mcvs add -R was adding only
282 directories, effectively ignoring arguments that are regular files.
283 The error-continuation behavior of mcvs add has been revised.
285 Trying to rename an object onto itself, or to move the sandbox root
286 directory are no longer silent no-ops, but produce an error.
288 The remap command now preserves property lists, and picks up changes
289 in executable permission.
291 The grab command now notices when a file changes from having execute
292 permission to not having execute permission.
294 Operations on the path . now work in a partial sandbox.
296 Release 0.96, 2002-09-21:
298 The restore command was left broken during the change to the new
299 filemap format. It is now fixed.
301 The grab command now handles execute permission bits properly.
303 Some more commands have detailed help.
305 There is now a global option -i which specifies a script to be
306 executed. This allows Meta-CVS to be scripted using Lisp. For
307 instance suppose you have the following script and call it
308 list-matching:
310 #!/usr/local/bin/mcvs -i
311 (in-sandbox-root-dir
312 (let ((mapping (mapping-read *mcvs-map*))
313 (test-func (eval (read-from-string (pop *args*)))))
314 (dolist (entry mapping)
315 (with-slots (path raw-plist) entry
316 (when (funcall test-func raw-plist)
317 (format t "~a~%" path))))))
319 Then to list the names of files whose "importance" property is
320 a value greater than two, run:
322 ./list-matching '(lambda (plist)
323 (let ((imp (getf plist :importance)))
324 (and imp (> imp 2))))'
326 WARNING: Scripting accesses the guts of Meta-CVS directly, so scripts may
327 break as Meta-CVS is maintained. There is currently no published set of
328 stable interfaces.
330 Release 0.95, 2002-09-16:
332 The install.sh script no longer uses a borrowed copy of the clisp-link script
333 or the linkkit directory; these have been removed. These materials
334 are available at every CLISP installation; install.sh now finds them
335 and uses them. Users of non-x86 machines ran into problems because of this
336 because linkkit/clisp.h contains architecture-dependent information.
338 A bug in mcvs filt was fixed; it wasn't handling F- names that aren't found
339 in the map.
341 A more detailed help system now exists, though it's not complete. The ``mcvs
342 help'' command acts just like ``mcvs --help'' without any arguments. If given
343 an additional parameter which specifies a Meta-CVS command, it produces more
344 detailed documentation for that comand. Help exists already for a few
345 commands.
347 The release number is being warped to 0.95, which means that Meta-CVS is now
348 in beta. It is only five updates away from a 1.0 release.
350 Release 0.24, 2002-09-08:
352 The mapping entries for both symlinks and files have extensible property
353 lists now. These are stored in the optional fourth and fifth list elements,
354 respectively of the :FILE and :SYMLINK map entries.
356 Versioning of the execute permission of files is supported, represented as
357 the :EXEC property of a :FILE mapping entry.
359 Some lame syntax is provided for manipulating properties:
361 mcvs prop --set foo --clear bar --remove baz main.c list.c
363 will set the property FOO to true, set the property BAR to false,
364 and remove the property BAZ, in the files main.c and list.c.
365 The execute permission is represented by the property EXEC.
367 Release 0.23, 2002-09-02:
369 Bugfix: the grab command notices edited symlinks and incorporates the
370 changes into the mapping.
372 The grab command now figures out moved symlinks. Moved symlinks are those
373 whose pathname has changed, but which continue to point to the same object
374 (which may also have been moved).
376 Release 0.22, 2002-08-31:
378 Symbolic links are now versioned objects. The format of the MAP file
379 changes to accomodate this; the new Meta-CVS will read old MAP
380 files; when it writes it will write the new format. Old Meta-CVS won't
381 read the new format.
383 When a new module is created from an existing file tree, symbolic
384 links will be recognized and added. The add command will also add
385 symbolic links. Symbolic links can be renamed and moved; this does
386 nothing with their contents. They can point outside of the sandbox
387 using relative or absolute paths.
389 TODO:
391 There doesn't exist yet a special command to create symbolic links, nor to
392 retarget them; retargetting a link can be done manually by editing MCVS/MAP
393 and updating. Retargetting a link using the ln -s command, won't
394 backpropagate to the MAP file; an update will clobber the link.
396 The grab command does not yet compute symbolic link moves; a moved symbolic
397 link is treated as a remove and add. This will be easy to fix.
399 The remap command ignores symlinks.
401 Release 0.21, 2002-08-04:
403 Syntax of grab command changed. The branch is no longer specified as an
404 argument, but using the -r command option. If no revision is specified with
405 -r, then a -A must be specified to make the grab go to the main trunk. This
406 is a safety feature, since grabbing foreign snapshots to the trunk is almost
407 always wrong, though it could be useful during backup recovery, or for fixing
408 mistakes.
410 The way operating system functions are targetted has changed. Instead of
411 relying on the ``linuxlibc6'' module provided by CLISP, Meta-CVS now
412 has its own module for calling foreign functions. This module is portable;
413 it does not depend on the layout of glibc data structures. So Meta-CVS
414 is in theory now portable to other Unixes (provided they have /dev/urandom).
416 Release 0.20, 2002-07-27:
418 The commit command does a true global commit when given no file or directory
419 parameters, and not given the --metaonly option. This means commiting all
420 changes in the MCVS directory, even if they are in F-files that are not
421 currently mapped.
423 Release 0.19, 2002-07-16:
425 When moving multiple files or directories to a subdirectory, a
426 restart is now provided to skip over bad ones and continue.
428 Grab no longer scans files if there are only added files, or only removed
429 files. There are no moves to deduce in that case.
431 Restore properly creates lost+found at the root of a partial sandbox,
432 rather than at the abstract root of the module.
434 Some other algorithmic improvements made.
436 The first few sections of a user guide have been written.
438 Release 0.18, 2002-07-07:
440 Cool new feature: checkout takes an extra argument, which specifies a
441 subdirectory of the project. Specifying a subdirectory results in a ``partial
442 sandbox'', whose root directory is the specified subdirectory of the larger
443 project. The rest of the project is ``invisible'' to that sandbox. A
444 subdirectory argument can also be given to mcvs grab, which will cause it to
445 integrate the new source tree against a subtree of the Meta-CVS project
446 rather than the entire project. The subtree doesn't have to exist; in
447 that case you get an empty sandbox. Adding files to this sandbox will cause
448 the tree to exist in the project.
450 Bugfix: mcvs grab was not computing moves properly over small file sets,
451 wrongly treating them as removes and adds.
453 Release 0.17, 2002-07-02:
455 The create command no longer takes a vendor branch. Instead the symbol
456 ``Created-by-Meta-CVS'' is used as the vendor tag to satisfy CVS.
458 The grab command no longer does useless synchronization on files that
459 are about to be deleted.
461 New purge command; does ``cvs rm'' on deleted files, that is to say, F- files
462 that have no mapping.
464 New restore command; re-enters deleted files into the mapping, under
465 the ``lost+found'' directory, using their F- names as sandbox names.
467 Bugfix: when a checkout bails because it is requested over top of an existing
468 working copy, it must not delete that working copy's MCVS sub directory.
470 Release 0.16, 2002-06-29:
472 Added new heuristics to grab command. Paths are analyzed to determine
473 move distance. Greater distances reduce the confidence in a move.
474 These rules help sort out grabs in a project where similar or
475 duplicate files are subject to parallel moves, the ambiguity being
476 resolved by favoring shorter moves. Word comparisons are case-insensitive
477 now. Common words (those that appear in many files) are ignored when
478 comparing files.
480 New options, --meta and --metaonly. This area of Meta-CVS is cleaned
481 up a little bit. Most reporting commands like log or diff no longer
482 operate on meta files by default; they must be explicitly told to do
483 so with --meta or --metaonly. Only the commit command implicitly includes
484 metafiles by default, and so if this is not wanted, --nometa must be
485 selected. The update command remains special; if it is given file
486 arguments, it does not include meta files. If given no arguments, it
487 does a global CVS up across the entire project.
489 Release 0.15, 2002-06-25:
491 Optimized a string splitting routine which is used heavily for processing
492 paths; the result is a noticeable performance improvement in some commands
493 that process large numbers of files.
495 Renamed ``import'' command to ``create''.
497 Bugfix: checkout and create showed errors when removing directory, due to
498 broken :postorder support in directory walking function.
500 Bugfix: on failure, checkout was failing to delete the MCVS directory when
501 the checkout was directed to an existing directory.
503 New feature: ``mcvs grab'' command imports third-party snapshots to a
504 branch. This is invoked in the root directory of the source tree to import.
505 It determines what files have been added and removed in the snapshot, and
506 tries to compute which removes and adds are actually moves. This is done by
507 analyzing the actual contents of the files according to a crude algorithm to
508 do fuzzy comparisons, so that even files which were modified as well as moved
509 are discovered.
511 Release 0.14, 2002-06-21:
513 Bugfix: mcvs add was broken for files that have no suffix, causing
514 the underlying cvs add to fail. This was broken in 0.7 when type
515 handling was added.
517 Release 0.13, 2002-06-06:
519 Sandbox synchronization now handles the case of two files having
520 the same timestamp. An error is signaled, with interactive resolution
521 to synchronize either way, or do nothing.
523 If a file must be deleted on update, and this cannot be done, it
524 is now a continuable error.
526 Bugfix: pass -I ! to cvs import so that it won't ignore some F- files
527 whose suffix is one of the ones cvs ignores by default.
529 New command: mcvs remap. The user can move or delete files directly without
530 going through Meta-CVS. When mcvs remap is invoked, it will hunt down the
531 moves and deletions, and reconstruct the mapping accordingly; that is,
532 it remaps the new structure. This command uses inode numbers to identify
533 files; if a file is copied and then the original is deleted, that won't
534 be recognized as a move.
536 Release 0.12, 2002-04-18:
538 Bugfix: remove was broken in 0.10, fixed now.
540 Bugfix: status, diff, etc. work in empty project rather than complaining
541 ``. not known to Meta-CVS''.
543 The checkout operation now can now populate an existing directory, including
544 the current working directory (mcvs co -d . modulename). Of course, the
545 target directory cannot be an existing Meta-CVS sandbox.
546 This is a useful feature, which allows sandboxes to blend with an
547 existing directory structure.
549 Checkout now uses the same function for generating the sandbox
550 structure as does update. This is now necessary, because local files
551 can be clobbered by the checkout.
553 Release 0.11, 2002-04-12:
555 Bugfix: when branch invokes rtag, it now takes the CVSROOT information
556 from CVS/Root and passes it via -d. This is necessary because rtag does not
557 look at a local CVS subdirectory for this information, only the
558 -d option or the environment variable.
560 Command for listing branches added (list-branches or lb). Also shows
561 what sticky tag the sandbox is updated to.
563 Command for switching branches added (switch or sw).
565 Merge detects that working copy is on non-branch tag and bails.
567 Absolute paths can now be specified as file arguments. These are
568 based from the root directory of the sandbox, not the actual filesystem root
569 directory.
571 Release 0.10, 2002-04-03:
573 Automatic merging implemented. Branch is created using branch command,
574 and merging from another branch is done using simple merge command.
575 Meta-CVS maintains the tags to keep track of what has been merged
576 from what branch to what branch.
578 Bugfix: checkout -d foo bar was complaining about directory bar already
579 existing, even though it should only care about foo.
581 The remove command now requires explicit -R option to recursively remove
582 a directory. It has more detailed error reporting.
584 The move command has better error reporting.
586 Release 0.9, 2002-03-14:
588 Bugfix: the .cvsignore file is now subject to tagging, status, etc,
589 (unless --nometa is specified, of course).
591 The mcvs filt command takes -r <revision> or -D <date> parameters.
592 This means to retrieve the MAP file as of the specified revision or
593 date and use that mapping to perform the filtering translation,
594 rather than using MAP-LOCAL.
596 The mcvs update command takes filename arguments now and also
597 supports the -p option.
599 Release 0.8, 2002-03-13:
601 Bug fixed in mcvs add; it was not ignoring files that are already
602 listed as :ignore in MCVS/TYPES.
604 Bug fixed in mcvs move: a target with a trailing slash is now treated
605 as a directory (if it does not already exist and is a non-directory).
607 The -d option of mcvs checkout can now be used to override the checkout
608 directory, which is normally the same as the module name.
610 The global options --version, --help, -q, -Q and -e are now supported.
612 New global options --error-continue and --error-terminate to disable
613 interactive error handling in two different ways.
615 Log level of many messages has changed; many messages have been
616 relegated to debug level.
618 The import command now creates a .cvsignore file containing the name
621 Release 0.7, 2002-03-09:
623 The import command collects a list of the file suffixes and brings up
624 a text editor to allow the user to edit their CVS keyword expansion
625 behavior. This information is kept in a new metafile called TYPES. The
626 add command also updates TYPES; it identifies any suffixes which are new,
627 and brings up an editor. The F- files now carry suffixes, which
628 simplifies interfacing with CVS, and also allows cvswrappers to work.
630 Recursive add works (mcvs add -R ...).
632 New command line option --nometa allows metafiles to be excluded from
633 diff, tag, and other commands; without the option they are inserted
634 into the list of files to be processed.
636 The commit option now takes an optional list of files or directories,
637 just like tag, diff, and others.
639 Release 0.6, 2002-02-16:
641 The add operation was horribly broken in 0.5, it is fixed.
643 User can interactively select whether to clobber local files or leave
644 everything alone. Effects on the mapping file of a mcvs move are undone,
645 if the restructuring is rolled back, or raises a condition that leads
646 to termination.
648 Meta-CVS now keeps a new meta-file called MCVS/TYPES. This is created
649 during import, and specifies the CVS keyword expansion mode for files
650 having given suffixes, and can also tell Meta-CVS to ignore certain files
651 when importing or adding.
653 Release 0.5, 2002-02-10:
655 Much improved error handling. Filesystem rearranging code performs
656 sanity checks to prevent adds and moves from accidentally clobbering
657 local files. A rearranging gone bad can be rolled back. Effects
658 of a failed mcvs add can also be rolled back.
660 MAP-LOCAL is now sorted in the same way as MAP.
662 Release 0.4, 2002-02-04:
664 CVS is invoked using internal function resembling the xargs utility,
665 which ensures that multiple command lines are generated if necessary to
666 avoid surpassing the operating system limit on argument and environment
667 vector size. This is important when someone wants to diff or stat a
668 subdirectory, which requires Meta-CVS to pick out the individual files
669 at the CVS level.
671 The tag, log, status and annotate commands are now available.
673 The MAP file is sorted on F- file names now, not path names. This
674 improves merging, since files do not move within the file when
675 they are renamed.
677 Release 0.3, 2002-02-02:
679 Process termination done is properly in top level handler, by a nonlocal
680 exit. The program properly indicates failed termination when it exits
681 due to an error condition.
683 Corrections are made in the command line option processing. If z is an
684 option that takes an argument, and the argument is -zx, then x is
685 treated as the argument to the option. Long options arguments are
686 recognized properly, according to the --opt=arg convention. The option
687 processing is restructured. Most of the commands now take the
688 appropriate cvs command-specific options.
690 The update algorithm performs dupe checking over the map, which could
691 happen during a merge.
693 Some more bugfixing has been done to the move command. It was still not
694 handling right some cases of an unversioned file being clobbered. Also,
695 it wasn't renaming a directory containing just one file.
697 I did some performance investigation for larger file sets, and
698 ended up rewriting the code that computes filesystem restructuring
699 changes and map duplicates.
701 Release 0.2, 2002-01-30:
703 Changed official name from MCVS to Meta-CVS. The move command now
704 performs some filesystem tests so it does the right thing when a versioned
705 file is moved over a non-versioned file, or when a file is moved into
706 a directory not known to Meta-CVS. Factored out reading and writing of
707 map files into functions.
709 Release 0.1, 2002-01-28:
711 Support for mcvs diff -u added. The -R option works for mcvs add command.
712 Bug fixed in mcvs mv command; it wasn't working analogously to the Unix
713 mv command when copying a directory to an existing directory.
715 Release 0.0, 2002-01-27:
717 This is alpha software. It is not complete, and lacks documentation.
718 However, it is already usable in its present state and is being used for
719 version control by its author. If you can program in Common Lisp and would
720 like to help, take a look through the TODO file. Send me patches, ideas,
721 feature requests.
