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