1 kaz 1.162 Release for Meta-CVS
2 kaz 1.1
3 kaz 1.142 Release ?.??, 200?-??-??:
4    
5 kaz 1.162 All Lisp symbols are in a package.
6 kaz 1.142
7 kaz 1.162 Release 1.0.4, 2003-02-20:
8    
9     Fix remaining occurences of the CVS ``No child processes'' abort
10     problem, affecting the list-branches command, merge command
11     and the -r option of the filt command.
12    
13     Release 1.0.3, 2003-02-12:
14    
15     ! THIS RELEASE IS WITHDRAWN. It was accidentally created from the
16     ! experimental main trunk of the Meta-CVS codebase, rather than
17     ! the 1.0 branch. But 1.0.4 does contain all of the changes
18     ! described here.
19 kaz 1.160
20     Fix for the CVS ``No child processes'' abort problem. It turns out
21     that CLISP sets the signal handling action for the SIGCHLD signal
22     to SIG_IGN, which is inherited by child processes across the
23     fork() and execvp() calls used in our mcvs_spawn() function.
24     We correct the problem by resetting the signal handler to SIG_DFL
25     just before executing the new process image.
26 kaz 1.161
27     New feature, --up option. The argument is a nonnegative integer value
28     (default is zero) which specifies how many sandbox nesting levels to
29     escape out of when locating the sandbox root. This helps work with
30     nested Meta-CVS sandboxes.
31 kaz 1.160
32 kaz 1.162 Release 1.0.2, 2003-02-10:
33 kaz 1.157
34     Bugfix in waitpid logic in the C library for running external processes;
35     we were not dealing with an interrupted waitpid.
36    
37 kaz 1.158 Behavior of mcvs tag is changed: when there are no filename arguments,
38     the whole tree is tagged including the metafiles. In other words, it
39     now works like the commit command.
40    
41 kaz 1.157 Release 1.0.1, 2003-01-30:
42 kaz 1.154
43     Hard link sync optimization: update of a subset of files, commit, and
44     other operations like log and diff don't need to synchronize all
45     hard links, just the ones operated on.
46    
47 kaz 1.155 The merge and remerge commands support -k option for overriding
48     CVS keyword expansion mode.
49    
50 kaz 1.156 Fixes to getcwd error handling.
51 kaz 1.157
52     Improvement in install.sh script's logic for locating CLISP installation
53     directory.
54 kaz 1.156
55 kaz 1.153 Release 1.0, 2003-01-01:
56 kaz 1.147
57 kaz 1.151 NOTE: It's not possible to upgrade to this release via mcvs-upgrade,
58     because it adds some new C functions to the Lisp executable.
59    
60 kaz 1.147 Security fix: read-time evaluation was not suppressed when reading
61     structured data, like MCVS/MAP and MCVS/TYPES. This means that it
62     was possible for Alice to check in something that would execute
63     arbitrary code on Bob's computer.
64    
65 kaz 1.148 Optimization: use fork and exec to launch CVS rather than CLISP's
66     run-program function, which indirects through the shell interpreter.
67 kaz 1.153 (On Cygwin, the spawnvp function is used).
68 kaz 1.148
69 kaz 1.149 Performance fix: stat() was being called superfluously by the
70     hard synchronization code, twice for each file.
71    
72 kaz 1.150 Build fix: install.sh works when CLISP executable is called ``lisp.exe'',
73     which is the case under Cygwin with newer CLISP releases.
74    
75 kaz 1.146 Release 0.99, 2002-11-17:
76 kaz 1.135
77 kaz 1.140 New link command for creating symbolic links.
78    
79 kaz 1.144 Global option -n (dry run---don't modify filesystem) is processed
80     internally now, not just passed to CVS.
81    
82 kaz 1.135 Failure to invoke text editor is handled.
83    
84 kaz 1.136 The -r option of filt is fixed; it has been broken since the change to the
85     new MAP format, because it was reading the raw map representation, not
86     passing it through the right conversion steps that are needed now.
87    
88 kaz 1.138 Bugfix to purge and remap commands: they were fooled by CVS-generated
89     files in the MCVS/CVS directory. Specifically, files having F- names, and a
90     the suffix ,t.
91    
92 kaz 1.141 Bugfix to add logic in directory restructuring: there was the possibility
93     of mistakingly taking a clobbered local file to be a new local version of
94     the added file, instead of replacing it. This could happen if the local
95     file had a future timestamp relative to the one coming from the repository.
96    
97 kaz 1.143 The prop command does not synchronize or write out map if no options are
98     specified.
99    
100 kaz 1.144 Help text added for move and branch commands. Help text for grab rewritten.
101 kaz 1.137
102 kaz 1.145 The CVSEDITOR and VISUAL environment variables are now checked, not
103     only EDITOR.
104    
105 kaz 1.134 Release 0.98, 2002-10-13:
106 kaz 1.128
107 kaz 1.133 The prop command was mistakenly reading from MAP-LOCAL and writing to MAP,
108     which could cause information loss if the two differ. It now reads from MAP
109     and writes to MAP. (The property changes propagate to MAP-LOCAL by the
110     update operation invoked by prop, as before).
111    
112     Invocation of external programs included in debug trace.
113 kaz 1.128
114     The filt command does not filter F- names if they are immediately preceded by
115     the MCVS/ prefix; such occurences are clearly concrete, sandbox-relative
116     references to the actual F- links, rather than abstract references.
117    
118 kaz 1.129 The update command now supports the -C option, to fetch the repository
119     copy, throwing away local changes. It also now honors the --metaonly
120     and --nometa options.
121 kaz 1.130
122     The export command has been added, for checking out documents without creating
123     a working copy (no MCVS directory in the root of the checkout).
124 kaz 1.131
125 kaz 1.133 The watch command has been added. Note that its syntax differs from that
126     of CVS.
127 kaz 1.132
128     The watchers, editors, edit, and unedit commands have been added.
129 kaz 1.134
130     A script called mcvs-upgrade is now included, and installs alongside the mcvs
131     script. This allows the Meta-CVS Lisp image to recompile and patch itself,
132     giving users of binary distributions an easy way to upgrade from source
133     code.
134    
135 kaz 1.127 Release 0.97, 2002-10-06:
136 kaz 1.119
137     Meta-CVS now builds and runs on Microsoft Windows, under Cygwin
138     (www.cygwin.com). It still relies on hard links, which requires
139     Windows 2000 or XP, and the NTFS filesystem. It probably won't
140     work over FAT.
141 kaz 1.120
142     New --debug option for verbose output.
143    
144     Cleaned up of error messages. Error messages don't specify prefixes like
145     ``mcvs-add:'' or ``mcvs-grab:'' any more. Rather, the error handler adds the
146     ``mcvs:'' prefix when printing the messages in a situation when the error is
147     not continuable.
148 kaz 1.119
149 kaz 1.121 Fixed bug introduced in release 0.13: mcvs add -R was adding only
150     directories, effectively ignoring arguments that are regular files.
151 kaz 1.122 The error-continuation behavior of mcvs add has been revised.
152 kaz 1.121
153 kaz 1.125 Trying to rename an object onto itself, or to move the sandbox root
154     directory are no longer silent no-ops, but produce an error.
155 kaz 1.123
156 kaz 1.124 The remap command now preserves property lists, and picks up changes
157     in executable permission.
158    
159     The grab command now notices when a file changes from having execute
160     permission to not having execute permission.
161    
162 kaz 1.126 Operations on the path . now work in a partial sandbox.
163    
164 kaz 1.118 Release 0.96, 2002-09-21:
165 kaz 1.110
166     The restore command was left broken during the change to the new
167     filemap format. It is now fixed.
168    
169 kaz 1.111 The grab command now handles execute permission bits properly.
170    
171 kaz 1.112 Some more commands have detailed help.
172    
173 kaz 1.113 There is now a global option -i which specifies a script to be
174 kaz 1.114 executed. This allows Meta-CVS to be scripted using Lisp. For
175     instance suppose you have the following script and call it
176     list-matching:
177 kaz 1.113
178     #!/usr/local/bin/mcvs -i
179     (in-sandbox-root-dir
180 kaz 1.114 (let ((mapping (mapping-read *mcvs-map*))
181 kaz 1.117 (test-func (eval (read-from-string (pop *args*)))))
182 kaz 1.114 (dolist (entry mapping)
183     (with-slots (path raw-plist) entry
184 kaz 1.117 (when (funcall test-func raw-plist)
185 kaz 1.114 (format t "~a~%" path))))))
186    
187     Then to list the names of files whose "importance" property is
188     a value greater than two, run:
189    
190     ./list-matching '(lambda (plist)
191     (let ((imp (getf plist :importance)))
192     (and imp (> imp 2))))'
193 kaz 1.117
194     WARNING: Scripting accesses the guts of Meta-CVS directly, so scripts may
195     break as Meta-CVS is maintained. There is currently no published set of
196     stable interfaces.
197 kaz 1.113
198 kaz 1.109 Release 0.95, 2002-09-16:
199 kaz 1.104
200 kaz 1.107 The install.sh script no longer uses a borrowed copy of the clisp-link script
201     or the linkkit directory; these have been removed. These materials
202     are available at every CLISP installation; install.sh now finds them
203     and uses them. Users of non-x86 machines ran into problems because of this
204     because linkkit/clisp.h contains architecture-dependent information.
205 kaz 1.104
206 kaz 1.105 A bug in mcvs filt was fixed; it wasn't handling F- names that aren't found
207     in the map.
208    
209 kaz 1.108 A more detailed help system now exists, though it's not complete. The ``mcvs
210     help'' command acts just like ``mcvs --help'' without any arguments. If given
211     an additional parameter which specifies a Meta-CVS command, it produces more
212     detailed documentation for that comand. Help exists already for a few
213     commands.
214    
215 kaz 1.107 The release number is being warped to 0.95, which means that Meta-CVS is now
216     in beta. It is only five updates away from a 1.0 release.
217 kaz 1.106
218 kaz 1.103 Release 0.24, 2002-09-08:
219 kaz 1.98
220 kaz 1.99 The mapping entries for both symlinks and files have extensible property
221     lists now. These are stored in the optional fourth and fifth list elements,
222     respectively of the :FILE and :SYMLINK map entries.
223    
224     Versioning of the execute permission of files is supported, represented as
225     the :EXEC property of a :FILE mapping entry.
226 kaz 1.98
227 kaz 1.100 Some lame syntax is provided for manipulating properties:
228    
229 kaz 1.102 mcvs prop --set foo --clear bar --remove baz main.c list.c
230 kaz 1.100
231     will set the property FOO to true, set the property BAR to false,
232     and remove the property BAZ, in the files main.c and list.c.
233     The execute permission is represented by the property EXEC.
234    
235 kaz 1.97 Release 0.23, 2002-09-02:
236 kaz 1.95
237 kaz 1.96 Bugfix: the grab command notices edited symlinks and incorporates the
238     changes into the mapping.
239    
240     The grab command now figures out moved symlinks. Moved symlinks are those
241     whose pathname has changed, but which continue to point to the same object
242     (which may also have been moved).
243 kaz 1.95
244 kaz 1.94 Release 0.22, 2002-08-31:
245 kaz 1.93
246     Symbolic links are now versioned objects. The format of the MAP file
247     changes to accomodate this; the new Meta-CVS will read old MAP
248     files; when it writes it will write the new format. Old Meta-CVS won't
249     read the new format.
250    
251     When a new module is created from an existing file tree, symbolic
252     links will be recognized and added. The add command will also add
253     symbolic links. Symbolic links can be renamed and moved; this does
254     nothing with their contents. They can point outside of the sandbox
255     using relative or absolute paths.
256    
257 kaz 1.94 TODO:
258    
259 kaz 1.93 There doesn't exist yet a special command to create symbolic links, nor to
260     retarget them; retargetting a link can be done manually by editing MCVS/MAP
261     and updating. Retargetting a link using the ln -s command, won't
262 kaz 1.94 backpropagate to the MAP file; an update will clobber the link.
263    
264     The grab command does not yet compute symbolic link moves; a moved symbolic
265     link is treated as a remove and add. This will be easy to fix.
266    
267     The remap command ignores symlinks.
268 kaz 1.93
269 kaz 1.92 Release 0.21, 2002-08-04:
270 kaz 1.88
271 kaz 1.89 Syntax of grab command changed. The branch is no longer specified as an
272     argument, but using the -r command option. If no revision is specified with
273     -r, then a -A must be specified to make the grab go to the main trunk. This
274     is a safety feature, since grabbing foreign snapshots to the trunk is almost
275     always wrong, though it could be useful during backup recovery, or for fixing
276     mistakes.
277    
278 kaz 1.91 The way operating system functions are targetted has changed. Instead of
279     relying on the ``linuxlibc6'' module provided by CLISP, Meta-CVS now
280     has its own module for calling foreign functions. This module is portable;
281     it does not depend on the layout of glibc data structures. So Meta-CVS
282     is in theory now portable to other Unixes (provided they have /dev/urandom).
283    
284 kaz 1.87 Release 0.20, 2002-07-27:
285 kaz 1.86
286     The commit command does a true global commit when given no file or directory
287     parameters, and not given the --metaonly option. This means commiting all
288     changes in the MCVS directory, even if they are in F-files that are not
289     currently mapped.
290    
291 kaz 1.85 Release 0.19, 2002-07-16:
292 kaz 1.81
293     When moving multiple files or directories to a subdirectory, a
294     restart is now provided to skip over bad ones and continue.
295    
296 kaz 1.83 Grab no longer scans files if there are only added files, or only removed
297     files. There are no moves to deduce in that case.
298    
299 kaz 1.84 Restore properly creates lost+found at the root of a partial sandbox,
300     rather than at the abstract root of the module.
301    
302 kaz 1.83 Some other algorithmic improvements made.
303 kaz 1.82
304     The first few sections of a user guide have been written.
305    
306 kaz 1.80 Release 0.18, 2002-07-07:
307 kaz 1.77
308 kaz 1.78 Cool new feature: checkout takes an extra argument, which specifies a
309     subdirectory of the project. Specifying a subdirectory results in a ``partial
310     sandbox'', whose root directory is the specified subdirectory of the larger
311     project. The rest of the project is ``invisible'' to that sandbox. A
312     subdirectory argument can also be given to mcvs grab, which will cause it to
313     integrate the new source tree against a subtree of the Meta-CVS project
314 kaz 1.79 rather than the entire project. The subtree doesn't have to exist; in
315     that case you get an empty sandbox. Adding files to this sandbox will cause
316     the tree to exist in the project.
317 kaz 1.78
318 kaz 1.77 Bugfix: mcvs grab was not computing moves properly over small file sets,
319     wrongly treating them as removes and adds.
320    
321 kaz 1.76 Release 0.17, 2002-07-02:
322 kaz 1.71
323     The create command no longer takes a vendor branch. Instead the symbol
324     ``Created-by-Meta-CVS'' is used as the vendor tag to satisfy CVS.
325    
326 kaz 1.72 The grab command no longer does useless synchronization on files that
327     are about to be deleted.
328    
329 kaz 1.75 New purge command; does ``cvs rm'' on deleted files, that is to say, F- files
330     that have no mapping.
331    
332     New restore command; re-enters deleted files into the mapping, under
333     the ``lost+found'' directory, using their F- names as sandbox names.
334 kaz 1.73
335 kaz 1.74 Bugfix: when a checkout bails because it is requested over top of an existing
336     working copy, it must not delete that working copy's MCVS sub directory.
337    
338 kaz 1.70 Release 0.16, 2002-06-29:
339 kaz 1.67
340     Added new heuristics to grab command. Paths are analyzed to determine
341     move distance. Greater distances reduce the confidence in a move.
342     These rules help sort out grabs in a project where similar or
343     duplicate files are subject to parallel moves, the ambiguity being
344 kaz 1.68 resolved by favoring shorter moves. Word comparisons are case-insensitive
345     now. Common words (those that appear in many files) are ignored when
346     comparing files.
347 kaz 1.67
348 kaz 1.69 New options, --meta and --metaonly. This area of Meta-CVS is cleaned
349     up a little bit. Most reporting commands like log or diff no longer
350     operate on meta files by default; they must be explicitly told to do
351     so with --meta or --metaonly. Only the commit command implicitly includes
352     metafiles by default, and so if this is not wanted, --nometa must be
353     selected. The update command remains special; if it is given file
354     arguments, it does not include meta files. If given no arguments, it
355     does a global CVS up across the entire project.
356    
357 kaz 1.66 Release 0.15, 2002-06-25:
358 kaz 1.61
359 kaz 1.65 Optimized a string splitting routine which is used heavily for processing
360     paths; the result is a noticeable performance improvement in some commands
361     that process large numbers of files.
362 kaz 1.61
363 kaz 1.62 Renamed ``import'' command to ``create''.
364    
365 kaz 1.65 Bugfix: checkout and create showed errors when removing directory, due to
366     broken :postorder support in directory walking function.
367 kaz 1.63
368 kaz 1.65 Bugfix: on failure, checkout was failing to delete the MCVS directory when
369     the checkout was directed to an existing directory.
370    
371 kaz 1.66 New feature: ``mcvs grab'' command imports third-party snapshots to a
372 kaz 1.65 branch. This is invoked in the root directory of the source tree to import.
373     It determines what files have been added and removed in the snapshot, and
374     tries to compute which removes and adds are actually moves. This is done by
375     analyzing the actual contents of the files according to a crude algorithm to
376     do fuzzy comparisons, so that even files which were modified as well as moved
377     are discovered.
378 kaz 1.64
379 kaz 1.60 Release 0.14, 2002-06-21:
380 kaz 1.59
381     Bugfix: mcvs add was broken for files that have no suffix, causing
382 kaz 1.60 the underlying cvs add to fail. This was broken in 0.7 when type
383     handling was added.
384 kaz 1.59
385 kaz 1.58 Release 0.13, 2002-06-06:
386 kaz 1.55
387     Sandbox synchronization now handles the case of two files having
388     the same timestamp. An error is signaled, with interactive resolution
389     to synchronize either way, or do nothing.
390    
391 kaz 1.56 If a file must be deleted on update, and this cannot be done, it
392     is now a continuable error.
393    
394     Bugfix: pass -I ! to cvs import so that it won't ignore some F- files
395     whose suffix is one of the ones cvs ignores by default.
396    
397 kaz 1.57 New command: mcvs remap. The user can move or delete files directly without
398     going through Meta-CVS. When mcvs remap is invoked, it will hunt down the
399     moves and deletions, and reconstruct the mapping accordingly; that is,
400     it remaps the new structure. This command uses inode numbers to identify
401     files; if a file is copied and then the original is deleted, that won't
402     be recognized as a move.
403    
404 kaz 1.53 Release 0.12, 2002-04-18:
405 kaz 1.51
406     Bugfix: remove was broken in 0.10, fixed now.
407    
408 kaz 1.54 Bugfix: status, diff, etc. work in empty project rather than complaining
409     ``. not known to Meta-CVS''.
410    
411 kaz 1.52 The checkout operation now can now populate an existing directory, including
412     the current working directory (mcvs co -d . modulename). Of course, the
413     target directory cannot be an existing Meta-CVS sandbox.
414     This is a useful feature, which allows sandboxes to blend with an
415     existing directory structure.
416    
417     Checkout now uses the same function for generating the sandbox
418     structure as does update. This is now necessary, because local files
419     can be clobbered by the checkout.
420    
421 kaz 1.50 Release 0.11, 2002-04-12:
422 kaz 1.46
423     Bugfix: when branch invokes rtag, it now takes the CVSROOT information
424     from CVS/Root and passes it via -d. This is necessary because rtag does not
425     look at a local CVS subdirectory for this information, only the
426     -d option or the environment variable.
427    
428 kaz 1.48 Command for listing branches added (list-branches or lb). Also shows
429     what sticky tag the sandbox is updated to.
430    
431     Command for switching branches added (switch or sw).
432    
433     Merge detects that working copy is on non-branch tag and bails.
434 kaz 1.47
435 kaz 1.49 Absolute paths can now be specified as file arguments. These are
436     based from the root directory of the sandbox, not the actual filesystem root
437     directory.
438    
439 kaz 1.45 Release 0.10, 2002-04-03:
440 kaz 1.44
441     Automatic merging implemented. Branch is created using branch command,
442     and merging from another branch is done using simple merge command.
443     Meta-CVS maintains the tags to keep track of what has been merged
444     from what branch to what branch.
445 kaz 1.40
446     Bugfix: checkout -d foo bar was complaining about directory bar already
447     existing, even though it should only care about foo.
448    
449 kaz 1.41 The remove command now requires explicit -R option to recursively remove
450 kaz 1.42 a directory. It has more detailed error reporting.
451 kaz 1.41
452 kaz 1.43 The move command has better error reporting.
453    
454 kaz 1.39 Release 0.9, 2002-03-14:
455 kaz 1.37
456     Bugfix: the .cvsignore file is now subject to tagging, status, etc,
457     (unless --nometa is specified, of course).
458 kaz 1.38
459     The mcvs filt command takes -r <revision> or -D <date> parameters.
460     This means to retrieve the MAP file as of the specified revision or
461     date and use that mapping to perform the filtering translation,
462     rather than using MAP-LOCAL.
463 kaz 1.39
464     The mcvs update command takes filename arguments now and also
465     supports the -p option.
466 kaz 1.37
467 kaz 1.36 Release 0.8, 2002-03-13:
468 kaz 1.28
469 kaz 1.29 Bug fixed in mcvs add; it was not ignoring files that are already
470     listed as :ignore in MCVS/TYPES.
471    
472 kaz 1.34 Bug fixed in mcvs move: a target with a trailing slash is now treated
473     as a directory (if it does not already exist and is a non-directory).
474    
475 kaz 1.30 The -d option of mcvs checkout can now be used to override the checkout
476     directory, which is normally the same as the module name.
477    
478 kaz 1.31 The global options --version, --help, -q, -Q and -e are now supported.
479    
480 kaz 1.33 New global options --error-continue and --error-terminate to disable
481     interactive error handling in two different ways.
482    
483 kaz 1.32 Log level of many messages has changed; many messages have been
484     relegated to debug level.
485    
486 kaz 1.35 The import command now creates a .cvsignore file containing the name
487     MAP-LOCAL.
488    
489 kaz 1.24 Release 0.7, 2002-03-09:
490    
491 kaz 1.27 The import command collects a list of the file suffixes and brings up
492     a text editor to allow the user to edit their CVS keyword expansion
493     behavior. This information is kept in a new metafile called TYPES. The
494     add command also updates TYPES; it identifies any suffixes which are new,
495     and brings up an editor. The F- files now carry suffixes, which
496     simplifies interfacing with CVS, and also allows cvswrappers to work.
497    
498     Recursive add works (mcvs add -R ...).
499    
500     New command line option --nometa allows metafiles to be excluded from
501     diff, tag, and other commands; without the option they are inserted
502     into the list of files to be processed.
503 kaz 1.25
504 kaz 1.27 The commit option now takes an optional list of files or directories,
505     just like tag, diff, and others.
506 kaz 1.26
507 kaz 1.23 Release 0.6, 2002-02-16:
508 kaz 1.19
509 kaz 1.27 The add operation was horribly broken in 0.5, it is fixed.
510 kaz 1.21
511 kaz 1.27 User can interactively select whether to clobber local files or leave
512     everything alone. Effects on the mapping file of a mcvs move are undone,
513     if the restructuring is rolled back, or raises a condition that leads
514     to termination.
515    
516     Meta-CVS now keeps a new meta-file called MCVS/TYPES. This is created
517     during import, and specifies the CVS keyword expansion mode for files
518     having given suffixes, and can also tell Meta-CVS to ignore certain files
519     when importing or adding.
520 kaz 1.22
521 kaz 1.18 Release 0.5, 2002-02-10:
522 kaz 1.14
523 kaz 1.27 Much improved error handling. Filesystem rearranging code performs
524     sanity checks to prevent adds and moves from accidentally clobbering
525     local files. A rearranging gone bad can be rolled back. Effects
526     of a failed mcvs add can also be rolled back.
527 kaz 1.14
528 kaz 1.27 MAP-LOCAL is now sorted in the same way as MAP.
529 kaz 1.15
530 kaz 1.13 Release 0.4, 2002-02-04:
531 kaz 1.10
532 kaz 1.27 CVS is invoked using internal function resembling the xargs utility,
533     which ensures that multiple command lines are generated if necessary to
534     avoid surpassing the operating system limit on argument and environment
535     vector size. This is important when someone wants to diff or stat a
536     subdirectory, which requires Meta-CVS to pick out the individual files
537     at the CVS level.
538    
539     The tag, log, status and annotate commands are now available.
540    
541     The MAP file is sorted on F- file names now, not path names. This
542     improves merging, since files do not move within the file when
543     they are renamed.
544 kaz 1.12
545 kaz 1.5 Release 0.3, 2002-02-02:
546    
547 kaz 1.27 Process termination done is properly in top level handler, by a nonlocal
548     exit. The program properly indicates failed termination when it exits
549     due to an error condition.
550    
551     Corrections are made in the command line option processing. If z is an
552     option that takes an argument, and the argument is -zx, then x is
553     treated as the argument to the option. Long options arguments are
554     recognized properly, according to the --opt=arg convention. The option
555     processing is restructured. Most of the commands now take the
556     appropriate cvs command-specific options.
557    
558     The update algorithm performs dupe checking over the map, which could
559     happen during a merge.
560    
561     Some more bugfixing has been done to the move command. It was still not
562     handling right some cases of an unversioned file being clobbered. Also,
563     it wasn't renaming a directory containing just one file.
564    
565     I did some performance investigation for larger file sets, and
566     ended up rewriting the code that computes filesystem restructuring
567     changes and map duplicates.
568 kaz 1.5
569 kaz 1.4 Release 0.2, 2002-01-30:
570    
571 kaz 1.27 Changed official name from MCVS to Meta-CVS. The move command now
572     performs some filesystem tests so it does the right thing when a versioned
573     file is moved over a non-versioned file, or when a file is moved into
574     a directory not known to Meta-CVS. Factored out reading and writing of
575     map files into functions.
576 kaz 1.4
577 kaz 1.2 Release 0.1, 2002-01-28:
578    
579 kaz 1.27 Support for mcvs diff -u added. The -R option works for mcvs add command.
580     Bug fixed in mcvs mv command; it wasn't working analogously to the Unix
581     mv command when copying a directory to an existing directory.
582 kaz 1.2
583     Release 0.0, 2002-01-27:
584 kaz 1.1
585 kaz 1.27 This is alpha software. It is not complete, and lacks documentation.
586     However, it is already usable in its present state and is being used for
587     version control by its author. If you can program in Common Lisp and would
588     like to help, take a look through the TODO file. Send me patches, ideas,
589     feature requests.
