* code/posix.lisp (invoke-editor-on): Honor the CVSEDITOR and VISUAL
environment variables, not just EDITOR.
1 kaz 1.115 Release Notes for Meta-CVS
2 kaz 1.1
3 kaz 1.127.2.11 Release 0.99, 2002-1?-??:
4    
5 kaz 1.127.2.16 New link command for creating symbolic links.
6    
7 kaz 1.127.2.20 Global option -n (dry run---don't modify filesystem) is processed
8     internally now, not just passed to CVS.
9    
10 kaz 1.127.2.11 Failure to invoke text editor is handled.
11    
12 kaz 1.127.2.12 The -r option of filt is fixed; it has been broken since the change to the
13     new MAP format, because it was reading the raw map representation, not
14     passing it through the right conversion steps that are needed now.
15    
16 kaz 1.127.2.14 Bugfix to purge and remap commands: they were fooled by CVS-generated
17     files in the MCVS/CVS directory. Specifically, files having F- names, and a
18     the suffix ,t.
19    
20 kaz 1.127.2.17 Bugfix to add logic in directory restructuring: there was the possibility
21     of mistakingly taking a clobbered local file to be a new local version of
22     the added file, instead of replacing it. This could happen if the local
23     file had a future timestamp relative to the one coming from the repository.
24    
25 kaz 1.127.2.18 The prop command does not synchronize or write out map if no options are
26     specified.
27    
28 kaz 1.127.2.19 Help text added for move and branch commands. Help text for grab rewritten.
29 kaz 1.127.2.13
30 kaz 1.127.2.21 The CVSEDITOR and VISUAL environment variables are now checked, not
31     only EDITOR.
32    
33 kaz 1.127.2.10 Release 0.98, 2002-10-13:
34 kaz 1.127.2.1
35 kaz 1.127.2.8 The prop command was mistakenly reading from MAP-LOCAL and writing to MAP,
36     which could cause information loss if the two differ. It now reads from MAP
37     and writes to MAP. (The property changes propagate to MAP-LOCAL by the
38     update operation invoked by prop, as before).
39    
40 kaz 1.127.2.7 Invocation of external programs included in debug trace.
41 kaz 1.127.2.1
42 kaz 1.127.2.2 The filt command does not filter F- names if they are immediately preceded by
43     the MCVS/ prefix; such occurences are clearly concrete, sandbox-relative
44     references to the actual F- links, rather than abstract references.
45    
46 kaz 1.127.2.3 The update command now supports the -C option, to fetch the repository
47     copy, throwing away local changes. It also now honors the --metaonly
48     and --nometa options.
49 kaz 1.127.2.4
50     The export command has been added, for checking out documents without creating
51     a working copy (no MCVS directory in the root of the checkout).
52 kaz 1.127.2.5
53 kaz 1.127.2.7 The watch command has been added. Note that its syntax differs from that
54     of CVS.
55 kaz 1.127.2.6
56     The watchers, editors, edit, and unedit commands have been added.
57 kaz 1.127.2.9
58     A script called mcvs-upgrade is now included, and installs alongside the mcvs
59     script. This allows the Meta-CVS Lisp image to recompile and patch itself,
60     giving users of binary distributions an easy way to upgrade from source
61     code.
62    
63 kaz 1.127 Release 0.97, 2002-10-06:
64 kaz 1.119
65     Meta-CVS now builds and runs on Microsoft Windows, under Cygwin
66     (www.cygwin.com). It still relies on hard links, which requires
67     Windows 2000 or XP, and the NTFS filesystem. It probably won't
68     work over FAT.
69 kaz 1.120
70     New --debug option for verbose output.
71    
72     Cleaned up of error messages. Error messages don't specify prefixes like
73     ``mcvs-add:'' or ``mcvs-grab:'' any more. Rather, the error handler adds the
74     ``mcvs:'' prefix when printing the messages in a situation when the error is
75     not continuable.
76 kaz 1.119
77 kaz 1.121 Fixed bug introduced in release 0.13: mcvs add -R was adding only
78     directories, effectively ignoring arguments that are regular files.
79 kaz 1.122 The error-continuation behavior of mcvs add has been revised.
80 kaz 1.121
81 kaz 1.125 Trying to rename an object onto itself, or to move the sandbox root
82     directory are no longer silent no-ops, but produce an error.
83 kaz 1.123
84 kaz 1.124 The remap command now preserves property lists, and picks up changes
85     in executable permission.
86    
87     The grab command now notices when a file changes from having execute
88     permission to not having execute permission.
89    
90 kaz 1.126 Operations on the path . now work in a partial sandbox.
91    
92 kaz 1.118 Release 0.96, 2002-09-21:
93 kaz 1.110
94     The restore command was left broken during the change to the new
95     filemap format. It is now fixed.
96    
97 kaz 1.111 The grab command now handles execute permission bits properly.
98    
99 kaz 1.112 Some more commands have detailed help.
100    
101 kaz 1.113 There is now a global option -i which specifies a script to be
102 kaz 1.114 executed. This allows Meta-CVS to be scripted using Lisp. For
103     instance suppose you have the following script and call it
104     list-matching:
105 kaz 1.113
106     #!/usr/local/bin/mcvs -i
107     (in-sandbox-root-dir
108 kaz 1.114 (let ((mapping (mapping-read *mcvs-map*))
109 kaz 1.117 (test-func (eval (read-from-string (pop *args*)))))
110 kaz 1.114 (dolist (entry mapping)
111     (with-slots (path raw-plist) entry
112 kaz 1.117 (when (funcall test-func raw-plist)
113 kaz 1.114 (format t "~a~%" path))))))
114    
115     Then to list the names of files whose "importance" property is
116     a value greater than two, run:
117    
118     ./list-matching '(lambda (plist)
119     (let ((imp (getf plist :importance)))
120     (and imp (> imp 2))))'
121 kaz 1.117
122     WARNING: Scripting accesses the guts of Meta-CVS directly, so scripts may
123     break as Meta-CVS is maintained. There is currently no published set of
124     stable interfaces.
125 kaz 1.113
126 kaz 1.109 Release 0.95, 2002-09-16:
127 kaz 1.104
128 kaz 1.107 The install.sh script no longer uses a borrowed copy of the clisp-link script
129     or the linkkit directory; these have been removed. These materials
130     are available at every CLISP installation; install.sh now finds them
131     and uses them. Users of non-x86 machines ran into problems because of this
132     because linkkit/clisp.h contains architecture-dependent information.
133 kaz 1.104
134 kaz 1.105 A bug in mcvs filt was fixed; it wasn't handling F- names that aren't found
135     in the map.
136    
137 kaz 1.108 A more detailed help system now exists, though it's not complete. The ``mcvs
138     help'' command acts just like ``mcvs --help'' without any arguments. If given
139     an additional parameter which specifies a Meta-CVS command, it produces more
140     detailed documentation for that comand. Help exists already for a few
141     commands.
142    
143 kaz 1.107 The release number is being warped to 0.95, which means that Meta-CVS is now
144     in beta. It is only five updates away from a 1.0 release.
145 kaz 1.106
146 kaz 1.103 Release 0.24, 2002-09-08:
147 kaz 1.98
148 kaz 1.99 The mapping entries for both symlinks and files have extensible property
149     lists now. These are stored in the optional fourth and fifth list elements,
150     respectively of the :FILE and :SYMLINK map entries.
151    
152     Versioning of the execute permission of files is supported, represented as
153     the :EXEC property of a :FILE mapping entry.
154 kaz 1.98
155 kaz 1.100 Some lame syntax is provided for manipulating properties:
156    
157 kaz 1.102 mcvs prop --set foo --clear bar --remove baz main.c list.c
158 kaz 1.100
159     will set the property FOO to true, set the property BAR to false,
160     and remove the property BAZ, in the files main.c and list.c.
161     The execute permission is represented by the property EXEC.
162    
163 kaz 1.97 Release 0.23, 2002-09-02:
164 kaz 1.95
165 kaz 1.96 Bugfix: the grab command notices edited symlinks and incorporates the
166     changes into the mapping.
167    
168     The grab command now figures out moved symlinks. Moved symlinks are those
169     whose pathname has changed, but which continue to point to the same object
170     (which may also have been moved).
171 kaz 1.95
172 kaz 1.94 Release 0.22, 2002-08-31:
173 kaz 1.93
174     Symbolic links are now versioned objects. The format of the MAP file
175     changes to accomodate this; the new Meta-CVS will read old MAP
176     files; when it writes it will write the new format. Old Meta-CVS won't
177     read the new format.
178    
179     When a new module is created from an existing file tree, symbolic
180     links will be recognized and added. The add command will also add
181     symbolic links. Symbolic links can be renamed and moved; this does
182     nothing with their contents. They can point outside of the sandbox
183     using relative or absolute paths.
184    
185 kaz 1.94 TODO:
186    
187 kaz 1.93 There doesn't exist yet a special command to create symbolic links, nor to
188     retarget them; retargetting a link can be done manually by editing MCVS/MAP
189     and updating. Retargetting a link using the ln -s command, won't
190 kaz 1.94 backpropagate to the MAP file; an update will clobber the link.
191    
192     The grab command does not yet compute symbolic link moves; a moved symbolic
193     link is treated as a remove and add. This will be easy to fix.
194    
195     The remap command ignores symlinks.
196 kaz 1.93
197 kaz 1.92 Release 0.21, 2002-08-04:
198 kaz 1.88
199 kaz 1.89 Syntax of grab command changed. The branch is no longer specified as an
200     argument, but using the -r command option. If no revision is specified with
201     -r, then a -A must be specified to make the grab go to the main trunk. This
202     is a safety feature, since grabbing foreign snapshots to the trunk is almost
203     always wrong, though it could be useful during backup recovery, or for fixing
204     mistakes.
205    
206 kaz 1.91 The way operating system functions are targetted has changed. Instead of
207     relying on the ``linuxlibc6'' module provided by CLISP, Meta-CVS now
208     has its own module for calling foreign functions. This module is portable;
209     it does not depend on the layout of glibc data structures. So Meta-CVS
210     is in theory now portable to other Unixes (provided they have /dev/urandom).
211    
212 kaz 1.87 Release 0.20, 2002-07-27:
213 kaz 1.86
214     The commit command does a true global commit when given no file or directory
215     parameters, and not given the --metaonly option. This means commiting all
216     changes in the MCVS directory, even if they are in F-files that are not
217     currently mapped.
218    
219 kaz 1.85 Release 0.19, 2002-07-16:
220 kaz 1.81
221     When moving multiple files or directories to a subdirectory, a
222     restart is now provided to skip over bad ones and continue.
223    
224 kaz 1.83 Grab no longer scans files if there are only added files, or only removed
225     files. There are no moves to deduce in that case.
226    
227 kaz 1.84 Restore properly creates lost+found at the root of a partial sandbox,
228     rather than at the abstract root of the module.
229    
230 kaz 1.83 Some other algorithmic improvements made.
231 kaz 1.82
232     The first few sections of a user guide have been written.
233    
234 kaz 1.80 Release 0.18, 2002-07-07:
235 kaz 1.77
236 kaz 1.78 Cool new feature: checkout takes an extra argument, which specifies a
237     subdirectory of the project. Specifying a subdirectory results in a ``partial
238     sandbox'', whose root directory is the specified subdirectory of the larger
239     project. The rest of the project is ``invisible'' to that sandbox. A
240     subdirectory argument can also be given to mcvs grab, which will cause it to
241     integrate the new source tree against a subtree of the Meta-CVS project
242 kaz 1.79 rather than the entire project. The subtree doesn't have to exist; in
243     that case you get an empty sandbox. Adding files to this sandbox will cause
244     the tree to exist in the project.
245 kaz 1.78
246 kaz 1.77 Bugfix: mcvs grab was not computing moves properly over small file sets,
247     wrongly treating them as removes and adds.
248    
249 kaz 1.76 Release 0.17, 2002-07-02:
250 kaz 1.71
251     The create command no longer takes a vendor branch. Instead the symbol
252     ``Created-by-Meta-CVS'' is used as the vendor tag to satisfy CVS.
253    
254 kaz 1.72 The grab command no longer does useless synchronization on files that
255     are about to be deleted.
256    
257 kaz 1.75 New purge command; does ``cvs rm'' on deleted files, that is to say, F- files
258     that have no mapping.
259    
260     New restore command; re-enters deleted files into the mapping, under
261     the ``lost+found'' directory, using their F- names as sandbox names.
262 kaz 1.73
263 kaz 1.74 Bugfix: when a checkout bails because it is requested over top of an existing
264     working copy, it must not delete that working copy's MCVS sub directory.
265    
266 kaz 1.70 Release 0.16, 2002-06-29:
267 kaz 1.67
268     Added new heuristics to grab command. Paths are analyzed to determine
269     move distance. Greater distances reduce the confidence in a move.
270     These rules help sort out grabs in a project where similar or
271     duplicate files are subject to parallel moves, the ambiguity being
272 kaz 1.68 resolved by favoring shorter moves. Word comparisons are case-insensitive
273     now. Common words (those that appear in many files) are ignored when
274     comparing files.
275 kaz 1.67
276 kaz 1.69 New options, --meta and --metaonly. This area of Meta-CVS is cleaned
277     up a little bit. Most reporting commands like log or diff no longer
278     operate on meta files by default; they must be explicitly told to do
279     so with --meta or --metaonly. Only the commit command implicitly includes
280     metafiles by default, and so if this is not wanted, --nometa must be
281     selected. The update command remains special; if it is given file
282     arguments, it does not include meta files. If given no arguments, it
283     does a global CVS up across the entire project.
284    
285 kaz 1.66 Release 0.15, 2002-06-25:
286 kaz 1.61
287 kaz 1.65 Optimized a string splitting routine which is used heavily for processing
288     paths; the result is a noticeable performance improvement in some commands
289     that process large numbers of files.
290 kaz 1.61
291 kaz 1.62 Renamed ``import'' command to ``create''.
292    
293 kaz 1.65 Bugfix: checkout and create showed errors when removing directory, due to
294     broken :postorder support in directory walking function.
295 kaz 1.63
296 kaz 1.65 Bugfix: on failure, checkout was failing to delete the MCVS directory when
297     the checkout was directed to an existing directory.
298    
299 kaz 1.66 New feature: ``mcvs grab'' command imports third-party snapshots to a
300 kaz 1.65 branch. This is invoked in the root directory of the source tree to import.
301     It determines what files have been added and removed in the snapshot, and
302     tries to compute which removes and adds are actually moves. This is done by
303     analyzing the actual contents of the files according to a crude algorithm to
304     do fuzzy comparisons, so that even files which were modified as well as moved
305     are discovered.
306 kaz 1.64
307 kaz 1.60 Release 0.14, 2002-06-21:
308 kaz 1.59
309     Bugfix: mcvs add was broken for files that have no suffix, causing
310 kaz 1.60 the underlying cvs add to fail. This was broken in 0.7 when type
311     handling was added.
312 kaz 1.59
313 kaz 1.58 Release 0.13, 2002-06-06:
314 kaz 1.55
315     Sandbox synchronization now handles the case of two files having
316     the same timestamp. An error is signaled, with interactive resolution
317     to synchronize either way, or do nothing.
318    
319 kaz 1.56 If a file must be deleted on update, and this cannot be done, it
320     is now a continuable error.
321    
322     Bugfix: pass -I ! to cvs import so that it won't ignore some F- files
323     whose suffix is one of the ones cvs ignores by default.
324    
325 kaz 1.57 New command: mcvs remap. The user can move or delete files directly without
326     going through Meta-CVS. When mcvs remap is invoked, it will hunt down the
327     moves and deletions, and reconstruct the mapping accordingly; that is,
328     it remaps the new structure. This command uses inode numbers to identify
329     files; if a file is copied and then the original is deleted, that won't
330     be recognized as a move.
331    
332 kaz 1.53 Release 0.12, 2002-04-18:
333 kaz 1.51
334     Bugfix: remove was broken in 0.10, fixed now.
335    
336 kaz 1.54 Bugfix: status, diff, etc. work in empty project rather than complaining
337     ``. not known to Meta-CVS''.
338    
339 kaz 1.52 The checkout operation now can now populate an existing directory, including
340     the current working directory (mcvs co -d . modulename). Of course, the
341     target directory cannot be an existing Meta-CVS sandbox.
342     This is a useful feature, which allows sandboxes to blend with an
343     existing directory structure.
344    
345     Checkout now uses the same function for generating the sandbox
346     structure as does update. This is now necessary, because local files
347     can be clobbered by the checkout.
348    
349 kaz 1.50 Release 0.11, 2002-04-12:
350 kaz 1.46
351     Bugfix: when branch invokes rtag, it now takes the CVSROOT information
352     from CVS/Root and passes it via -d. This is necessary because rtag does not
353     look at a local CVS subdirectory for this information, only the
354     -d option or the environment variable.
355    
356 kaz 1.48 Command for listing branches added (list-branches or lb). Also shows
357     what sticky tag the sandbox is updated to.
358    
359     Command for switching branches added (switch or sw).
360    
361     Merge detects that working copy is on non-branch tag and bails.
362 kaz 1.47
363 kaz 1.49 Absolute paths can now be specified as file arguments. These are
364     based from the root directory of the sandbox, not the actual filesystem root
365     directory.
366    
367 kaz 1.45 Release 0.10, 2002-04-03:
368 kaz 1.44
369     Automatic merging implemented. Branch is created using branch command,
370     and merging from another branch is done using simple merge command.
371     Meta-CVS maintains the tags to keep track of what has been merged
372     from what branch to what branch.
373 kaz 1.40
374     Bugfix: checkout -d foo bar was complaining about directory bar already
375     existing, even though it should only care about foo.
376    
377 kaz 1.41 The remove command now requires explicit -R option to recursively remove
378 kaz 1.42 a directory. It has more detailed error reporting.
379 kaz 1.41
380 kaz 1.43 The move command has better error reporting.
381    
382 kaz 1.39 Release 0.9, 2002-03-14:
383 kaz 1.37
384     Bugfix: the .cvsignore file is now subject to tagging, status, etc,
385     (unless --nometa is specified, of course).
386 kaz 1.38
387     The mcvs filt command takes -r <revision> or -D <date> parameters.
388     This means to retrieve the MAP file as of the specified revision or
389     date and use that mapping to perform the filtering translation,
390     rather than using MAP-LOCAL.
391 kaz 1.39
392     The mcvs update command takes filename arguments now and also
393     supports the -p option.
394 kaz 1.37
395 kaz 1.36 Release 0.8, 2002-03-13:
396 kaz 1.28
397 kaz 1.29 Bug fixed in mcvs add; it was not ignoring files that are already
398     listed as :ignore in MCVS/TYPES.
399    
400 kaz 1.34 Bug fixed in mcvs move: a target with a trailing slash is now treated
401     as a directory (if it does not already exist and is a non-directory).
402    
403 kaz 1.30 The -d option of mcvs checkout can now be used to override the checkout
404     directory, which is normally the same as the module name.
405    
406 kaz 1.31 The global options --version, --help, -q, -Q and -e are now supported.
407    
408 kaz 1.33 New global options --error-continue and --error-terminate to disable
409     interactive error handling in two different ways.
410    
411 kaz 1.32 Log level of many messages has changed; many messages have been
412     relegated to debug level.
413    
414 kaz 1.35 The import command now creates a .cvsignore file containing the name
415     MAP-LOCAL.
416    
417 kaz 1.24 Release 0.7, 2002-03-09:
418    
419 kaz 1.27 The import command collects a list of the file suffixes and brings up
420     a text editor to allow the user to edit their CVS keyword expansion
421     behavior. This information is kept in a new metafile called TYPES. The
422     add command also updates TYPES; it identifies any suffixes which are new,
423     and brings up an editor. The F- files now carry suffixes, which
424     simplifies interfacing with CVS, and also allows cvswrappers to work.
425    
426     Recursive add works (mcvs add -R ...).
427    
428     New command line option --nometa allows metafiles to be excluded from
429     diff, tag, and other commands; without the option they are inserted
430     into the list of files to be processed.
431 kaz 1.25
432 kaz 1.27 The commit option now takes an optional list of files or directories,
433     just like tag, diff, and others.
434 kaz 1.26
435 kaz 1.23 Release 0.6, 2002-02-16:
436 kaz 1.19
437 kaz 1.27 The add operation was horribly broken in 0.5, it is fixed.
438 kaz 1.21
439 kaz 1.27 User can interactively select whether to clobber local files or leave
440     everything alone. Effects on the mapping file of a mcvs move are undone,
441     if the restructuring is rolled back, or raises a condition that leads
442     to termination.
443    
444     Meta-CVS now keeps a new meta-file called MCVS/TYPES. This is created
445     during import, and specifies the CVS keyword expansion mode for files
446     having given suffixes, and can also tell Meta-CVS to ignore certain files
447     when importing or adding.
448 kaz 1.22
449 kaz 1.18 Release 0.5, 2002-02-10:
450 kaz 1.14
451 kaz 1.27 Much improved error handling. Filesystem rearranging code performs
452     sanity checks to prevent adds and moves from accidentally clobbering
453     local files. A rearranging gone bad can be rolled back. Effects
454     of a failed mcvs add can also be rolled back.
455 kaz 1.14
456 kaz 1.27 MAP-LOCAL is now sorted in the same way as MAP.
457 kaz 1.15
458 kaz 1.13 Release 0.4, 2002-02-04:
459 kaz 1.10
460 kaz 1.27 CVS is invoked using internal function resembling the xargs utility,
461     which ensures that multiple command lines are generated if necessary to
462     avoid surpassing the operating system limit on argument and environment
463     vector size. This is important when someone wants to diff or stat a
464     subdirectory, which requires Meta-CVS to pick out the individual files
465     at the CVS level.
466    
467     The tag, log, status and annotate commands are now available.
468    
469     The MAP file is sorted on F- file names now, not path names. This
470     improves merging, since files do not move within the file when
471     they are renamed.
472 kaz 1.12
473 kaz 1.5 Release 0.3, 2002-02-02:
474    
475 kaz 1.27 Process termination done is properly in top level handler, by a nonlocal
476     exit. The program properly indicates failed termination when it exits
477     due to an error condition.
478    
479     Corrections are made in the command line option processing. If z is an
480     option that takes an argument, and the argument is -zx, then x is
481     treated as the argument to the option. Long options arguments are
482     recognized properly, according to the --opt=arg convention. The option
483     processing is restructured. Most of the commands now take the
484     appropriate cvs command-specific options.
485    
486     The update algorithm performs dupe checking over the map, which could
487     happen during a merge.
488    
489     Some more bugfixing has been done to the move command. It was still not
490     handling right some cases of an unversioned file being clobbered. Also,
491     it wasn't renaming a directory containing just one file.
492    
493     I did some performance investigation for larger file sets, and
494     ended up rewriting the code that computes filesystem restructuring
495     changes and map duplicates.
496 kaz 1.5
497 kaz 1.4 Release 0.2, 2002-01-30:
498    
499 kaz 1.27 Changed official name from MCVS to Meta-CVS. The move command now
500     performs some filesystem tests so it does the right thing when a versioned
501     file is moved over a non-versioned file, or when a file is moved into
502     a directory not known to Meta-CVS. Factored out reading and writing of
503     map files into functions.
504 kaz 1.4
505 kaz 1.2 Release 0.1, 2002-01-28:
506    
507 kaz 1.27 Support for mcvs diff -u added. The -R option works for mcvs add command.
508     Bug fixed in mcvs mv command; it wasn't working analogously to the Unix
509     mv command when copying a directory to an existing directory.
510 kaz 1.2
511     Release 0.0, 2002-01-27:
512 kaz 1.1
513 kaz 1.27 This is alpha software. It is not complete, and lacks documentation.
514     However, it is already usable in its present state and is being used for
515     version control by its author. If you can program in Common Lisp and would
516     like to help, take a look through the TODO file. Send me patches, ideas,
517     feature requests.
