Branch: MAIN
Changes since 1.183: +7 -1 lines
Merging from mcvs-1-0-branch.
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 1.184 Release 1.0.12, 2004-0?-??:
8    
9     Fixes path handling bug in ``mcvs convert'', so that it is
10     actually useable now, albeit still far from a perfect CVS
11     migration tool.
12    
13     Release 1.0.11, 2004-01-28:
14 kaz 1.182
15 kaz 1.183 Fixes breakage of list-branches command introduced in last release.
16    
17     Fixes failures in grab command when pulling new baseline over
18     partial sandbox. Renamed symlinks, and execute permissions of files
19     were being accessed using abstract instead of real path.
20 kaz 1.182
21 kaz 1.181 Release 1.0.10, 2004-01-09:
22    
23     Builds on CLISP 2.32. The lb command no longer produces bogus warning
24     when working copy is sticky to a version tag.
25    
26 kaz 1.180 Release 1.0.9, 2003-11-24:
27 kaz 1.178
28     Failures to open terminal for reasons other than non-existence
29     of the object are handled (e.g. ``no such device'', etc).
30    
31 kaz 1.179 The --nometa option now works properly in those commands that
32     operate on the whole project when no file arguments are given
33     (tag, update, commit). Also, these commands no longer implicitly
34     include the meta files when file arguments *are* given.
35     These files can be included explicitly with the --meta global option.
36    
37 kaz 1.177 Release 1.0.8, 2003-06-03:
38 kaz 1.174
39 kaz 1.175 The Cygwin /dev/tty problem is partially addressed. The program
40     won't fail if /dev does not exist, but emits a warning message,
41     and disables interactive error handling. The workaround is to use
42     ``mkdir /dev''. This is a CLISP issue; its OPEN function expects the
43     full path to a file to actually exist, but on Cygwin, there are fake
44     /dev/* paths even though /dev does not exist. If a real /dev directory
45     does in fact exist, it does not interfere with these magic paths.
46 kaz 1.174
47 kaz 1.176 The ``mcvs fi'' command no longer performs expansion on F- names
48     that are preceded by a slash.
49    
50 kaz 1.174 Release 1.0.7, 2003-04-23:
51 kaz 1.170
52 kaz 1.173 New commands sync-to-cvs and sync-from-cvs expose the hard link
53     synchronization algorithm.
54    
55 kaz 1.170 Revamped error recovery logic. To continue in an error situation now
56     consistently means ``take the bold action that may erase data''
57     or ``proceed in the most obvious way to finish the specified job''.
58 kaz 1.172 It never means ``roll back the operation and bail'', which was
59     confusing.
60 kaz 1.170
61 kaz 1.172 Termination is no longer unsafe; the `T' menu command, and the
62     equivalent --error-terminate global option perform all necessary
63     restoration and cleanup.
64    
65     Errors that have more information to print, like a list of files or
66     whatever, now indicate it in a standard way which translates to the
67     `I' menu command.
68 kaz 1.171
69     Chatter output goes to standard error rather than standard output,
70     as do all error messages.
71    
72     The interactive error menu now talks to the user using the controlling
73     tty, meaning that it will work even if the input or output of the
74 kaz 1.172 mcvs command are redirected. If no controlling tty is available,
75     then interactive error handling is disabled; the default behavior
76     is then like --error-terminate but can of course be overridden by
77     --error-continue.
78 kaz 1.171
79 kaz 1.169 Release 1.0.6, 2003-04-14:
80 kaz 1.166
81     The create command detects the existence of text editor backup files (or
82     other junk) in the MCVS directory after the editor is invoked on the
83     TYPES file. The user is prompted regarding their removal. If these files are
84     not removed, cvs import will bring them into the repository.
85    
86 kaz 1.167 When Meta-CVS has to split a large CVS command into two or more
87     invocations with shorter argument lists, it now does not stop when one of
88     these invocations is unsuccessful; it does all of them, and combines
89     their termination indications by a logical AND. There was a bug in this
90     logic also which caused, upon termination failure, a cvs command to be
91     repeated for the same list of files.
92    
93     Synchronization logic has been revamped. Unnecessary synchronizations
94     have been removed, which will make some commands run faster.
95     Synchronizations now have specific directions; for instance before
96     a CVS commit or update, changes are pushed from the directory tree to the MCVS
97     directory only, and after the CVS operation, in the reverse direction only.
98    
99     Meta-CVS will no longer re-create missing F- files by linking from the
100     directory tree. Doing this causes two problems. One is that if a user
101     manually removes a F- file and do ``mcvs up'', she wants CVS to fetch a clean
102     copy and push it into the tree. She does not want the file to be restored
103     from the tree prior to the CVS update. Secondly, sometimes CVS itself
104     removes files. If we re-create the files, CVS will consider them to
105     be ``in the way''.
106    
107     Failures to read from the MAP or MAP-LOCAL files are treated as interactive,
108     continuable errors. By continuing, the user agrees that the behavior will
109     be as if an empty map were read.
110    
111 kaz 1.168 The grab command uses less memory for performing move analysis.
112    
113 kaz 1.165 Release 1.0.5, 2003-02-25:
114 kaz 1.163
115     Bugfix: some one-argument command line options of CVS must be
116     specifies as a single parameter, with no separation between the
117     option letter and the argument characters. For example:
118    
119     cvs log -r rev-1::rev-2 # invalid
120     cvs log -rrev1::rev2 # correct
121    
122     Meta-CVS accepts either syntax, but it was generating the first form
123     when calling CVS. Now, *all* one-letter options that have an argument
124     are formatted in the second manner.
125    
126 kaz 1.164 Bugfix: one more waitpid() issue was fixed; on fast machines, under
127     Linux, it was observed that from time to time Meta-CVS would get
128     a -1/ECHILD when waiting for the CVS process.
129    
130 kaz 1.162 Release 1.0.4, 2003-02-20:
131    
132     Fix remaining occurences of the CVS ``No child processes'' abort
133     problem, affecting the list-branches command, merge command
134     and the -r option of the filt command.
135    
136     Release 1.0.3, 2003-02-12:
137    
138     ! THIS RELEASE IS WITHDRAWN. It was accidentally created from the
139     ! experimental main trunk of the Meta-CVS codebase, rather than
140     ! the 1.0 branch. But 1.0.4 does contain all of the changes
141     ! described here.
142 kaz 1.160
143     Fix for the CVS ``No child processes'' abort problem. It turns out
144     that CLISP sets the signal handling action for the SIGCHLD signal
145     to SIG_IGN, which is inherited by child processes across the
146     fork() and execvp() calls used in our mcvs_spawn() function.
147     We correct the problem by resetting the signal handler to SIG_DFL
148     just before executing the new process image.
149 kaz 1.161
150     New feature, --up option. The argument is a nonnegative integer value
151     (default is zero) which specifies how many sandbox nesting levels to
152     escape out of when locating the sandbox root. This helps work with
153     nested Meta-CVS sandboxes.
154 kaz 1.160
155 kaz 1.162 Release 1.0.2, 2003-02-10:
156 kaz 1.157
157     Bugfix in waitpid logic in the C library for running external processes;
158     we were not dealing with an interrupted waitpid.
159    
160 kaz 1.158 Behavior of mcvs tag is changed: when there are no filename arguments,
161     the whole tree is tagged including the metafiles. In other words, it
162     now works like the commit command.
163    
164 kaz 1.157 Release 1.0.1, 2003-01-30:
165 kaz 1.154
166     Hard link sync optimization: update of a subset of files, commit, and
167     other operations like log and diff don't need to synchronize all
168     hard links, just the ones operated on.
169    
170 kaz 1.155 The merge and remerge commands support -k option for overriding
171     CVS keyword expansion mode.
172    
173 kaz 1.156 Fixes to getcwd error handling.
174 kaz 1.157
175     Improvement in install.sh script's logic for locating CLISP installation
176     directory.
177 kaz 1.156
178 kaz 1.153 Release 1.0, 2003-01-01:
179 kaz 1.147
180 kaz 1.151 NOTE: It's not possible to upgrade to this release via mcvs-upgrade,
181     because it adds some new C functions to the Lisp executable.
182    
183 kaz 1.147 Security fix: read-time evaluation was not suppressed when reading
184     structured data, like MCVS/MAP and MCVS/TYPES. This means that it
185     was possible for Alice to check in something that would execute
186     arbitrary code on Bob's computer.
187    
188 kaz 1.148 Optimization: use fork and exec to launch CVS rather than CLISP's
189     run-program function, which indirects through the shell interpreter.
190 kaz 1.153 (On Cygwin, the spawnvp function is used).
191 kaz 1.148
192 kaz 1.149 Performance fix: stat() was being called superfluously by the
193     hard synchronization code, twice for each file.
194    
195 kaz 1.150 Build fix: install.sh works when CLISP executable is called ``lisp.exe'',
196     which is the case under Cygwin with newer CLISP releases.
197    
198 kaz 1.146 Release 0.99, 2002-11-17:
199 kaz 1.135
200 kaz 1.140 New link command for creating symbolic links.
201    
202 kaz 1.144 Global option -n (dry run---don't modify filesystem) is processed
203     internally now, not just passed to CVS.
204    
205 kaz 1.135 Failure to invoke text editor is handled.
206    
207 kaz 1.136 The -r option of filt is fixed; it has been broken since the change to the
208     new MAP format, because it was reading the raw map representation, not
209     passing it through the right conversion steps that are needed now.
210    
211 kaz 1.138 Bugfix to purge and remap commands: they were fooled by CVS-generated
212     files in the MCVS/CVS directory. Specifically, files having F- names, and a
213     the suffix ,t.
214    
215 kaz 1.141 Bugfix to add logic in directory restructuring: there was the possibility
216     of mistakingly taking a clobbered local file to be a new local version of
217     the added file, instead of replacing it. This could happen if the local
218     file had a future timestamp relative to the one coming from the repository.
219    
220 kaz 1.143 The prop command does not synchronize or write out map if no options are
221     specified.
222    
223 kaz 1.144 Help text added for move and branch commands. Help text for grab rewritten.
224 kaz 1.137
225 kaz 1.145 The CVSEDITOR and VISUAL environment variables are now checked, not
226     only EDITOR.
227    
228 kaz 1.134 Release 0.98, 2002-10-13:
229 kaz 1.128
230 kaz 1.133 The prop command was mistakenly reading from MAP-LOCAL and writing to MAP,
231     which could cause information loss if the two differ. It now reads from MAP
232     and writes to MAP. (The property changes propagate to MAP-LOCAL by the
233     update operation invoked by prop, as before).
234    
235     Invocation of external programs included in debug trace.
236 kaz 1.128
237     The filt command does not filter F- names if they are immediately preceded by
238     the MCVS/ prefix; such occurences are clearly concrete, sandbox-relative
239     references to the actual F- links, rather than abstract references.
240    
241 kaz 1.129 The update command now supports the -C option, to fetch the repository
242     copy, throwing away local changes. It also now honors the --metaonly
243     and --nometa options.
244 kaz 1.130
245     The export command has been added, for checking out documents without creating
246     a working copy (no MCVS directory in the root of the checkout).
247 kaz 1.131
248 kaz 1.133 The watch command has been added. Note that its syntax differs from that
249     of CVS.
250 kaz 1.132
251     The watchers, editors, edit, and unedit commands have been added.
252 kaz 1.134
253     A script called mcvs-upgrade is now included, and installs alongside the mcvs
254     script. This allows the Meta-CVS Lisp image to recompile and patch itself,
255     giving users of binary distributions an easy way to upgrade from source
256     code.
257    
258 kaz 1.127 Release 0.97, 2002-10-06:
259 kaz 1.119
260     Meta-CVS now builds and runs on Microsoft Windows, under Cygwin
261     (www.cygwin.com). It still relies on hard links, which requires
262     Windows 2000 or XP, and the NTFS filesystem. It probably won't
263     work over FAT.
264 kaz 1.120
265     New --debug option for verbose output.
266    
267     Cleaned up of error messages. Error messages don't specify prefixes like
268     ``mcvs-add:'' or ``mcvs-grab:'' any more. Rather, the error handler adds the
269     ``mcvs:'' prefix when printing the messages in a situation when the error is
270     not continuable.
271 kaz 1.119
272 kaz 1.121 Fixed bug introduced in release 0.13: mcvs add -R was adding only
273     directories, effectively ignoring arguments that are regular files.
274 kaz 1.122 The error-continuation behavior of mcvs add has been revised.
275 kaz 1.121
276 kaz 1.125 Trying to rename an object onto itself, or to move the sandbox root
277     directory are no longer silent no-ops, but produce an error.
278 kaz 1.123
279 kaz 1.124 The remap command now preserves property lists, and picks up changes
280     in executable permission.
281    
282     The grab command now notices when a file changes from having execute
283     permission to not having execute permission.
284    
285 kaz 1.126 Operations on the path . now work in a partial sandbox.
286    
287 kaz 1.118 Release 0.96, 2002-09-21:
288 kaz 1.110
289     The restore command was left broken during the change to the new
290     filemap format. It is now fixed.
291    
292 kaz 1.111 The grab command now handles execute permission bits properly.
293    
294 kaz 1.112 Some more commands have detailed help.
295    
296 kaz 1.113 There is now a global option -i which specifies a script to be
297 kaz 1.114 executed. This allows Meta-CVS to be scripted using Lisp. For
298     instance suppose you have the following script and call it
299     list-matching:
300 kaz 1.113
301     #!/usr/local/bin/mcvs -i
302     (in-sandbox-root-dir
303 kaz 1.114 (let ((mapping (mapping-read *mcvs-map*))
304 kaz 1.117 (test-func (eval (read-from-string (pop *args*)))))
305 kaz 1.114 (dolist (entry mapping)
306     (with-slots (path raw-plist) entry
307 kaz 1.117 (when (funcall test-func raw-plist)
308 kaz 1.114 (format t "~a~%" path))))))
309    
310     Then to list the names of files whose "importance" property is
311     a value greater than two, run:
312    
313     ./list-matching '(lambda (plist)
314     (let ((imp (getf plist :importance)))
315     (and imp (> imp 2))))'
316 kaz 1.117
317     WARNING: Scripting accesses the guts of Meta-CVS directly, so scripts may
318     break as Meta-CVS is maintained. There is currently no published set of
319     stable interfaces.
320 kaz 1.113
321 kaz 1.109 Release 0.95, 2002-09-16:
322 kaz 1.104
323 kaz 1.107 The install.sh script no longer uses a borrowed copy of the clisp-link script
324     or the linkkit directory; these have been removed. These materials
325     are available at every CLISP installation; install.sh now finds them
326     and uses them. Users of non-x86 machines ran into problems because of this
327     because linkkit/clisp.h contains architecture-dependent information.
328 kaz 1.104
329 kaz 1.105 A bug in mcvs filt was fixed; it wasn't handling F- names that aren't found
330     in the map.
331    
332 kaz 1.108 A more detailed help system now exists, though it's not complete. The ``mcvs
333     help'' command acts just like ``mcvs --help'' without any arguments. If given
334     an additional parameter which specifies a Meta-CVS command, it produces more
335     detailed documentation for that comand. Help exists already for a few
336     commands.
337    
338 kaz 1.107 The release number is being warped to 0.95, which means that Meta-CVS is now
339     in beta. It is only five updates away from a 1.0 release.
340 kaz 1.106
341 kaz 1.103 Release 0.24, 2002-09-08:
342 kaz 1.98
343 kaz 1.99 The mapping entries for both symlinks and files have extensible property
344     lists now. These are stored in the optional fourth and fifth list elements,
345     respectively of the :FILE and :SYMLINK map entries.
346    
347     Versioning of the execute permission of files is supported, represented as
348     the :EXEC property of a :FILE mapping entry.
349 kaz 1.98
350 kaz 1.100 Some lame syntax is provided for manipulating properties:
351    
352 kaz 1.102 mcvs prop --set foo --clear bar --remove baz main.c list.c
353 kaz 1.100
354     will set the property FOO to true, set the property BAR to false,
355     and remove the property BAZ, in the files main.c and list.c.
356     The execute permission is represented by the property EXEC.
357    
358 kaz 1.97 Release 0.23, 2002-09-02:
359 kaz 1.95
360 kaz 1.96 Bugfix: the grab command notices edited symlinks and incorporates the
361     changes into the mapping.
362    
363     The grab command now figures out moved symlinks. Moved symlinks are those
364     whose pathname has changed, but which continue to point to the same object
365     (which may also have been moved).
366 kaz 1.95
367 kaz 1.94 Release 0.22, 2002-08-31:
368 kaz 1.93
369     Symbolic links are now versioned objects. The format of the MAP file
370     changes to accomodate this; the new Meta-CVS will read old MAP
371     files; when it writes it will write the new format. Old Meta-CVS won't
372     read the new format.
373    
374     When a new module is created from an existing file tree, symbolic
375     links will be recognized and added. The add command will also add
376     symbolic links. Symbolic links can be renamed and moved; this does
377     nothing with their contents. They can point outside of the sandbox
378     using relative or absolute paths.
379    
380 kaz 1.94 TODO:
381    
382 kaz 1.93 There doesn't exist yet a special command to create symbolic links, nor to
383     retarget them; retargetting a link can be done manually by editing MCVS/MAP
384     and updating. Retargetting a link using the ln -s command, won't
385 kaz 1.94 backpropagate to the MAP file; an update will clobber the link.
386    
387     The grab command does not yet compute symbolic link moves; a moved symbolic
388     link is treated as a remove and add. This will be easy to fix.
389    
390     The remap command ignores symlinks.
391 kaz 1.93
392 kaz 1.92 Release 0.21, 2002-08-04:
393 kaz 1.88
394 kaz 1.89 Syntax of grab command changed. The branch is no longer specified as an
395     argument, but using the -r command option. If no revision is specified with
396     -r, then a -A must be specified to make the grab go to the main trunk. This
397     is a safety feature, since grabbing foreign snapshots to the trunk is almost
398     always wrong, though it could be useful during backup recovery, or for fixing
399     mistakes.
400    
401 kaz 1.91 The way operating system functions are targetted has changed. Instead of
402     relying on the ``linuxlibc6'' module provided by CLISP, Meta-CVS now
403     has its own module for calling foreign functions. This module is portable;
404     it does not depend on the layout of glibc data structures. So Meta-CVS
405     is in theory now portable to other Unixes (provided they have /dev/urandom).
406    
407 kaz 1.87 Release 0.20, 2002-07-27:
408 kaz 1.86
409     The commit command does a true global commit when given no file or directory
410     parameters, and not given the --metaonly option. This means commiting all
411     changes in the MCVS directory, even if they are in F-files that are not
412     currently mapped.
413    
414 kaz 1.85 Release 0.19, 2002-07-16:
415 kaz 1.81
416     When moving multiple files or directories to a subdirectory, a
417     restart is now provided to skip over bad ones and continue.
418    
419 kaz 1.83 Grab no longer scans files if there are only added files, or only removed
420     files. There are no moves to deduce in that case.
421    
422 kaz 1.84 Restore properly creates lost+found at the root of a partial sandbox,
423     rather than at the abstract root of the module.
424    
425 kaz 1.83 Some other algorithmic improvements made.
426 kaz 1.82
427     The first few sections of a user guide have been written.

429 kaz 1.80 Release 0.18, 2002-07-07:
430 kaz 1.77
431 kaz 1.78 Cool new feature: checkout takes an extra argument, which specifies a
432     subdirectory of the project. Specifying a subdirectory results in a ``partial
433     sandbox'', whose root directory is the specified subdirectory of the larger
434     project. The rest of the project is ``invisible'' to that sandbox. A
435     subdirectory argument can also be given to mcvs grab, which will cause it to
436     integrate the new source tree against a subtree of the Meta-CVS project
437 kaz 1.79 rather than the entire project. The subtree doesn't have to exist; in
438     that case you get an empty sandbox. Adding files to this sandbox will cause
439     the tree to exist in the project.
440 kaz 1.78
441 kaz 1.77 Bugfix: mcvs grab was not computing moves properly over small file sets,
442     wrongly treating them as removes and adds.
443    
444 kaz 1.76 Release 0.17, 2002-07-02:
445 kaz 1.71
446     The create command no longer takes a vendor branch. Instead the symbol
447     ``Created-by-Meta-CVS'' is used as the vendor tag to satisfy CVS.
448    
449 kaz 1.72 The grab command no longer does useless synchronization on files that
450     are about to be deleted.
451    
452 kaz 1.75 New purge command; does ``cvs rm'' on deleted files, that is to say, F- files
453     that have no mapping.
454    
455     New restore command; re-enters deleted files into the mapping, under
456     the ``lost+found'' directory, using their F- names as sandbox names.
457 kaz 1.73
458 kaz 1.74 Bugfix: when a checkout bails because it is requested over top of an existing
459     working copy, it must not delete that working copy's MCVS sub directory.
460    
461 kaz 1.70 Release 0.16, 2002-06-29:
462 kaz 1.67
463     Added new heuristics to grab command. Paths are analyzed to determine
464     move distance. Greater distances reduce the confidence in a move.
465     These rules help sort out grabs in a project where similar or
466     duplicate files are subject to parallel moves, the ambiguity being
467 kaz 1.68 resolved by favoring shorter moves. Word comparisons are case-insensitive
468     now. Common words (those that appear in many files) are ignored when
469     comparing files.
470 kaz 1.67
471 kaz 1.69 New options, --meta and --metaonly. This area of Meta-CVS is cleaned
472     up a little bit. Most reporting commands like log or diff no longer
473     operate on meta files by default; they must be explicitly told to do
474     so with --meta or --metaonly. Only the commit command implicitly includes
475     metafiles by default, and so if this is not wanted, --nometa must be
476     selected. The update command remains special; if it is given file
477     arguments, it does not include meta files. If given no arguments, it
478     does a global CVS up across the entire project.
479    
480 kaz 1.66 Release 0.15, 2002-06-25:
481 kaz 1.61
482 kaz 1.65 Optimized a string splitting routine which is used heavily for processing
483     paths; the result is a noticeable performance improvement in some commands
484     that process large numbers of files.
485 kaz 1.61
486 kaz 1.62 Renamed ``import'' command to ``create''.
487    
488 kaz 1.65 Bugfix: checkout and create showed errors when removing directory, due to
489     broken :postorder support in directory walking function.
490 kaz 1.63
491 kaz 1.65 Bugfix: on failure, checkout was failing to delete the MCVS directory when
492     the checkout was directed to an existing directory.
493    
494 kaz 1.66 New feature: ``mcvs grab'' command imports third-party snapshots to a
495 kaz 1.65 branch. This is invoked in the root directory of the source tree to import.
496     It determines what files have been added and removed in the snapshot, and
497     tries to compute which removes and adds are actually moves. This is done by
498     analyzing the actual contents of the files according to a crude algorithm to
499     do fuzzy comparisons, so that even files which were modified as well as moved
500     are discovered.
501 kaz 1.64
502 kaz 1.60 Release 0.14, 2002-06-21:
503 kaz 1.59
504     Bugfix: mcvs add was broken for files that have no suffix, causing
505 kaz 1.60 the underlying cvs add to fail. This was broken in 0.7 when type
506     handling was added.
507 kaz 1.59
508 kaz 1.58 Release 0.13, 2002-06-06:
509 kaz 1.55
510     Sandbox synchronization now handles the case of two files having
511     the same timestamp. An error is signaled, with interactive resolution
512     to synchronize either way, or do nothing.
513    
514 kaz 1.56 If a file must be deleted on update, and this cannot be done, it
515     is now a continuable error.
516    
517     Bugfix: pass -I ! to cvs import so that it won't ignore some F- files
518     whose suffix is one of the ones cvs ignores by default.
519    
520 kaz 1.57 New command: mcvs remap. The user can move or delete files directly without
521     going through Meta-CVS. When mcvs remap is invoked, it will hunt down the
522     moves and deletions, and reconstruct the mapping accordingly; that is,
523     it remaps the new structure. This command uses inode numbers to identify
524     files; if a file is copied and then the original is deleted, that won't
525     be recognized as a move.
526    
527 kaz 1.53 Release 0.12, 2002-04-18:
528 kaz 1.51
529     Bugfix: remove was broken in 0.10, fixed now.
530    
531 kaz 1.54 Bugfix: status, diff, etc. work in empty project rather than complaining
532     ``. not known to Meta-CVS''.
533    
534 kaz 1.52 The checkout operation now can now populate an existing directory, including
535     the current working directory (mcvs co -d . modulename). Of course, the
536     target directory cannot be an existing Meta-CVS sandbox.
537     This is a useful feature, which allows sandboxes to blend with an
538     existing directory structure.
539    
540     Checkout now uses the same function for generating the sandbox
541     structure as does update. This is now necessary, because local files
542     can be clobbered by the checkout.
543    
544 kaz 1.50 Release 0.11, 2002-04-12:
545 kaz 1.46
546     Bugfix: when branch invokes rtag, it now takes the CVSROOT information
547     from CVS/Root and passes it via -d. This is necessary because rtag does not
548     look at a local CVS subdirectory for this information, only the
549     -d option or the environment variable.
550    
551 kaz 1.48 Command for listing branches added (list-branches or lb). Also shows
552     what sticky tag the sandbox is updated to.
553    
554     Command for switching branches added (switch or sw).
555    
556     Merge detects that working copy is on non-branch tag and bails.
557 kaz 1.47
558 kaz 1.49 Absolute paths can now be specified as file arguments. These are
559     based from the root directory of the sandbox, not the actual filesystem root
560     directory.
561    
562 kaz 1.45 Release 0.10, 2002-04-03:
563 kaz 1.44
564     Automatic merging implemented. Branch is created using branch command,
565     and merging from another branch is done using simple merge command.
566     Meta-CVS maintains the tags to keep track of what has been merged
567     from what branch to what branch.
568 kaz 1.40
569     Bugfix: checkout -d foo bar was complaining about directory bar already
570     existing, even though it should only care about foo.
571    
572 kaz 1.41 The remove command now requires explicit -R option to recursively remove
573 kaz 1.42 a directory. It has more detailed error reporting.
574 kaz 1.41
575 kaz 1.43 The move command has better error reporting.
576    
577 kaz 1.39 Release 0.9, 2002-03-14:
578 kaz 1.37
579     Bugfix: the .cvsignore file is now subject to tagging, status, etc,
580     (unless --nometa is specified, of course).
581 kaz 1.38
582     The mcvs filt command takes -r <revision> or -D <date> parameters.
583     This means to retrieve the MAP file as of the specified revision or
584     date and use that mapping to perform the filtering translation,
585     rather than using MAP-LOCAL.
586 kaz 1.39
587     The mcvs update command takes filename arguments now and also
588     supports the -p option.
589 kaz 1.37
590 kaz 1.36 Release 0.8, 2002-03-13:
591 kaz 1.28
592 kaz 1.29 Bug fixed in mcvs add; it was not ignoring files that are already
593     listed as :ignore in MCVS/TYPES.
594    
595 kaz 1.34 Bug fixed in mcvs move: a target with a trailing slash is now treated
596     as a directory (if it does not already exist and is a non-directory).
597    
598 kaz 1.30 The -d option of mcvs checkout can now be used to override the checkout
599     directory, which is normally the same as the module name.
600    
601 kaz 1.31 The global options --version, --help, -q, -Q and -e are now supported.
602    
603 kaz 1.33 New global options --error-continue and --error-terminate to disable
604     interactive error handling in two different ways.
605    
606 kaz 1.32 Log level of many messages has changed; many messages have been
607     relegated to debug level.
608    
609 kaz 1.35 The import command now creates a .cvsignore file containing the name
610     MAP-LOCAL.
611    
612 kaz 1.24 Release 0.7, 2002-03-09:
613    
614 kaz 1.27 The import command collects a list of the file suffixes and brings up
615     a text editor to allow the user to edit their CVS keyword expansion
616     behavior. This information is kept in a new metafile called TYPES. The
617     add command also updates TYPES; it identifies any suffixes which are new,
618     and brings up an editor. The F- files now carry suffixes, which
619     simplifies interfacing with CVS, and also allows cvswrappers to work.
620    
621     Recursive add works (mcvs add -R ...).
622    
623     New command line option --nometa allows metafiles to be excluded from
624     diff, tag, and other commands; without the option they are inserted
625     into the list of files to be processed.
626 kaz 1.25
627 kaz 1.27 The commit option now takes an optional list of files or directories,
628     just like tag, diff, and others.
629 kaz 1.26
630 kaz 1.23 Release 0.6, 2002-02-16:
631 kaz 1.19
632 kaz 1.27 The add operation was horribly broken in 0.5, it is fixed.
633 kaz 1.21
634 kaz 1.27 User can interactively select whether to clobber local files or leave
635     everything alone. Effects on the mapping file of a mcvs move are undone,
636     if the restructuring is rolled back, or raises a condition that leads
637     to termination.
638    
639     Meta-CVS now keeps a new meta-file called MCVS/TYPES. This is created
640     during import, and specifies the CVS keyword expansion mode for files
641     having given suffixes, and can also tell Meta-CVS to ignore certain files
642     when importing or adding.
643 kaz 1.22
644 kaz 1.18 Release 0.5, 2002-02-10:
645 kaz 1.14
646 kaz 1.27 Much improved error handling. Filesystem rearranging code performs
647     sanity checks to prevent adds and moves from accidentally clobbering
648     local files. A rearranging gone bad can be rolled back. Effects
649     of a failed mcvs add can also be rolled back.
650 kaz 1.14
651 kaz 1.27 MAP-LOCAL is now sorted in the same way as MAP.
652 kaz 1.15
653 kaz 1.13 Release 0.4, 2002-02-04:
654 kaz 1.10
655 kaz 1.27 CVS is invoked using internal function resembling the xargs utility,
656     which ensures that multiple command lines are generated if necessary to
657     avoid surpassing the operating system limit on argument and environment
658     vector size. This is important when someone wants to diff or stat a
659     subdirectory, which requires Meta-CVS to pick out the individual files
660     at the CVS level.
661    
662     The tag, log, status and annotate commands are now available.
663    
664     The MAP file is sorted on F- file names now, not path names. This
665     improves merging, since files do not move within the file when
666     they are renamed.
667 kaz 1.12
668 kaz 1.5 Release 0.3, 2002-02-02:
669    
670 kaz 1.27 Process termination done is properly in top level handler, by a nonlocal
671     exit. The program properly indicates failed termination when it exits
672     due to an error condition.
673    
674     Corrections are made in the command line option processing. If z is an
675     option that takes an argument, and the argument is -zx, then x is
676     treated as the argument to the option. Long options arguments are
677     recognized properly, according to the --opt=arg convention. The option
678     processing is restructured. Most of the commands now take the
679     appropriate cvs command-specific options.
680    
681     The update algorithm performs dupe checking over the map, which could
682     happen during a merge.
683    
684     Some more bugfixing has been done to the move command. It was still not
685     handling right some cases of an unversioned file being clobbered. Also,
686     it wasn't renaming a directory containing just one file.
687    
688     I did some performance investigation for larger file sets, and
689     ended up rewriting the code that computes filesystem restructuring
690     changes and map duplicates.
691 kaz 1.5
692 kaz 1.4 Release 0.2, 2002-01-30:
693    
694 kaz 1.27 Changed official name from MCVS to Meta-CVS. The move command now
695     performs some filesystem tests so it does the right thing when a versioned
696     file is moved over a non-versioned file, or when a file is moved into
697     a directory not known to Meta-CVS. Factored out reading and writing of
698     map files into functions.
699 kaz 1.4
700 kaz 1.2 Release 0.1, 2002-01-28:
701    
702 kaz 1.27 Support for mcvs diff -u added. The -R option works for mcvs add command.
703     Bug fixed in mcvs mv command; it wasn't working analogously to the Unix
704     mv command when copying a directory to an existing directory.
705 kaz 1.2
706     Release 0.0, 2002-01-27:
707 kaz 1.1
708 kaz 1.27 This is alpha software. It is not complete, and lacks documentation.
709     However, it is already usable in its present state and is being used for
710     version control by its author. If you can program in Common Lisp and would
711     like to help, take a look through the TODO file. Send me patches, ideas,
712     feature requests.
