Clarify that non-existent subdirectories can be specified on checkout.
1 kaz 1.3 Release Notes for Meta-CVS
2 kaz 1.1
3 kaz 1.77 Release 0.18, 2002-07-??:
5 kaz 1.78 Cool new feature: checkout takes an extra argument, which specifies a
6     subdirectory of the project. Specifying a subdirectory results in a ``partial
7     sandbox'', whose root directory is the specified subdirectory of the larger
8     project. The rest of the project is ``invisible'' to that sandbox. A
9     subdirectory argument can also be given to mcvs grab, which will cause it to
10     integrate the new source tree against a subtree of the Meta-CVS project
11 kaz 1.79 rather than the entire project. The subtree doesn't have to exist; in
12     that case you get an empty sandbox. Adding files to this sandbox will cause
13     the tree to exist in the project.
14 kaz 1.78
15 kaz 1.77 Bugfix: mcvs grab was not computing moves properly over small file sets,
16     wrongly treating them as removes and adds.
18 kaz 1.76 Release 0.17, 2002-07-02:
19 kaz 1.71
20     The create command no longer takes a vendor branch. Instead the symbol
21     ``Created-by-Meta-CVS'' is used as the vendor tag to satisfy CVS.
23 kaz 1.72 The grab command no longer does useless synchronization on files that
24     are about to be deleted.
26 kaz 1.75 New purge command; does ``cvs rm'' on deleted files, that is to say, F- files
27     that have no mapping.
29     New restore command; re-enters deleted files into the mapping, under
30     the ``lost+found'' directory, using their F- names as sandbox names.
31 kaz 1.73
32 kaz 1.74 Bugfix: when a checkout bails because it is requested over top of an existing
33     working copy, it must not delete that working copy's MCVS sub directory.
35 kaz 1.70 Release 0.16, 2002-06-29:
36 kaz 1.67
37     Added new heuristics to grab command. Paths are analyzed to determine
38     move distance. Greater distances reduce the confidence in a move.
39     These rules help sort out grabs in a project where similar or
40     duplicate files are subject to parallel moves, the ambiguity being
41 kaz 1.68 resolved by favoring shorter moves. Word comparisons are case-insensitive
42     now. Common words (those that appear in many files) are ignored when
43     comparing files.
44 kaz 1.67
45 kaz 1.69 New options, --meta and --metaonly. This area of Meta-CVS is cleaned
46     up a little bit. Most reporting commands like log or diff no longer
47     operate on meta files by default; they must be explicitly told to do
48     so with --meta or --metaonly. Only the commit command implicitly includes
49     metafiles by default, and so if this is not wanted, --nometa must be
50     selected. The update command remains special; if it is given file
51     arguments, it does not include meta files. If given no arguments, it
52     does a global CVS up across the entire project.
54 kaz 1.66 Release 0.15, 2002-06-25:
55 kaz 1.61
56 kaz 1.65 Optimized a string splitting routine which is used heavily for processing
57     paths; the result is a noticeable performance improvement in some commands
58     that process large numbers of files.
59 kaz 1.61
60 kaz 1.62 Renamed ``import'' command to ``create''.
62 kaz 1.65 Bugfix: checkout and create showed errors when removing directory, due to
63     broken :postorder support in directory walking function.
64 kaz 1.63
65 kaz 1.65 Bugfix: on failure, checkout was failing to delete the MCVS directory when
66     the checkout was directed to an existing directory.
68 kaz 1.66 New feature: ``mcvs grab'' command imports third-party snapshots to a
69 kaz 1.65 branch. This is invoked in the root directory of the source tree to import.
70     It determines what files have been added and removed in the snapshot, and
71     tries to compute which removes and adds are actually moves. This is done by
72     analyzing the actual contents of the files according to a crude algorithm to
73     do fuzzy comparisons, so that even files which were modified as well as moved
74     are discovered.
75 kaz 1.64
76 kaz 1.60 Release 0.14, 2002-06-21:
77 kaz 1.59
78     Bugfix: mcvs add was broken for files that have no suffix, causing
79 kaz 1.60 the underlying cvs add to fail. This was broken in 0.7 when type
80     handling was added.
81 kaz 1.59
82 kaz 1.58 Release 0.13, 2002-06-06:
83 kaz 1.55
84     Sandbox synchronization now handles the case of two files having
85     the same timestamp. An error is signaled, with interactive resolution
86     to synchronize either way, or do nothing.
88 kaz 1.56 If a file must be deleted on update, and this cannot be done, it
89     is now a continuable error.
91     Bugfix: pass -I ! to cvs import so that it won't ignore some F- files
92     whose suffix is one of the ones cvs ignores by default.
94 kaz 1.57 New command: mcvs remap. The user can move or delete files directly without
95     going through Meta-CVS. When mcvs remap is invoked, it will hunt down the
96     moves and deletions, and reconstruct the mapping accordingly; that is,
97     it remaps the new structure. This command uses inode numbers to identify
98     files; if a file is copied and then the original is deleted, that won't
99     be recognized as a move.
101 kaz 1.53 Release 0.12, 2002-04-18:
102 kaz 1.51
103     Bugfix: remove was broken in 0.10, fixed now.
105 kaz 1.54 Bugfix: status, diff, etc. work in empty project rather than complaining
106     ``. not known to Meta-CVS''.
108 kaz 1.52 The checkout operation now can now populate an existing directory, including
109     the current working directory (mcvs co -d . modulename). Of course, the
110     target directory cannot be an existing Meta-CVS sandbox.
111     This is a useful feature, which allows sandboxes to blend with an
112     existing directory structure.
114     Checkout now uses the same function for generating the sandbox
115     structure as does update. This is now necessary, because local files
116     can be clobbered by the checkout.
118 kaz 1.50 Release 0.11, 2002-04-12:
119 kaz 1.46
120     Bugfix: when branch invokes rtag, it now takes the CVSROOT information
121     from CVS/Root and passes it via -d. This is necessary because rtag does not
122     look at a local CVS subdirectory for this information, only the
123     -d option or the environment variable.
125 kaz 1.48 Command for listing branches added (list-branches or lb). Also shows
126     what sticky tag the sandbox is updated to.
128     Command for switching branches added (switch or sw).
130     Merge detects that working copy is on non-branch tag and bails.
131 kaz 1.47
132 kaz 1.49 Absolute paths can now be specified as file arguments. These are
133     based from the root directory of the sandbox, not the actual filesystem root
134     directory.
136 kaz 1.45 Release 0.10, 2002-04-03:
137 kaz 1.44
138     Automatic merging implemented. Branch is created using branch command,
139     and merging from another branch is done using simple merge command.
140     Meta-CVS maintains the tags to keep track of what has been merged
141     from what branch to what branch.
142 kaz 1.40
143     Bugfix: checkout -d foo bar was complaining about directory bar already
144     existing, even though it should only care about foo.
146 kaz 1.41 The remove command now requires explicit -R option to recursively remove
147 kaz 1.42 a directory. It has more detailed error reporting.
148 kaz 1.41
149 kaz 1.43 The move command has better error reporting.
151 kaz 1.39 Release 0.9, 2002-03-14:
152 kaz 1.37
153     Bugfix: the .cvsignore file is now subject to tagging, status, etc,
154     (unless --nometa is specified, of course).
155 kaz 1.38
156     The mcvs filt command takes -r <revision> or -D <date> parameters.
157     This means to retrieve the MAP file as of the specified revision or
158     date and use that mapping to perform the filtering translation,
159     rather than using MAP-LOCAL.
160 kaz 1.39
161     The mcvs update command takes filename arguments now and also
162     supports the -p option.
163 kaz 1.37
164 kaz 1.36 Release 0.8, 2002-03-13:
165 kaz 1.28
166 kaz 1.29 Bug fixed in mcvs add; it was not ignoring files that are already
167     listed as :ignore in MCVS/TYPES.
169 kaz 1.34 Bug fixed in mcvs move: a target with a trailing slash is now treated
170     as a directory (if it does not already exist and is a non-directory).
172 kaz 1.30 The -d option of mcvs checkout can now be used to override the checkout
173     directory, which is normally the same as the module name.
175 kaz 1.31 The global options --version, --help, -q, -Q and -e are now supported.
177 kaz 1.33 New global options --error-continue and --error-terminate to disable
178     interactive error handling in two different ways.
180 kaz 1.32 Log level of many messages has changed; many messages have been
181     relegated to debug level.
183 kaz 1.35 The import command now creates a .cvsignore file containing the name
184     MAP-LOCAL.
186 kaz 1.24 Release 0.7, 2002-03-09:
188 kaz 1.27 The import command collects a list of the file suffixes and brings up
189     a text editor to allow the user to edit their CVS keyword expansion
190     behavior. This information is kept in a new metafile called TYPES. The
191     add command also updates TYPES; it identifies any suffixes which are new,
192     and brings up an editor. The F- files now carry suffixes, which
193     simplifies interfacing with CVS, and also allows cvswrappers to work.
195     Recursive add works (mcvs add -R ...).
197     New command line option --nometa allows metafiles to be excluded from
198     diff, tag, and other commands; without the option they are inserted
199     into the list of files to be processed.
200 kaz 1.25
201 kaz 1.27 The commit option now takes an optional list of files or directories,
202     just like tag, diff, and others.
203 kaz 1.26
204 kaz 1.23 Release 0.6, 2002-02-16:
205 kaz 1.19
206 kaz 1.27 The add operation was horribly broken in 0.5, it is fixed.
207 kaz 1.21
208 kaz 1.27 User can interactively select whether to clobber local files or leave
209     everything alone. Effects on the mapping file of a mcvs move are undone,
210     if the restructuring is rolled back, or raises a condition that leads
211     to termination.
213     Meta-CVS now keeps a new meta-file called MCVS/TYPES. This is created
214     during import, and specifies the CVS keyword expansion mode for files
215     having given suffixes, and can also tell Meta-CVS to ignore certain files
216     when importing or adding.
217 kaz 1.22
218 kaz 1.18 Release 0.5, 2002-02-10:
219 kaz 1.14
220 kaz 1.27 Much improved error handling. Filesystem rearranging code performs
221     sanity checks to prevent adds and moves from accidentally clobbering
222     local files. A rearranging gone bad can be rolled back. Effects
223     of a failed mcvs add can also be rolled back.
224 kaz 1.14
225 kaz 1.27 MAP-LOCAL is now sorted in the same way as MAP.
226 kaz 1.15
227 kaz 1.13 Release 0.4, 2002-02-04:
228 kaz 1.10
229 kaz 1.27 CVS is invoked using internal function resembling the xargs utility,
230     which ensures that multiple command lines are generated if necessary to
231     avoid surpassing the operating system limit on argument and environment
232     vector size. This is important when someone wants to diff or stat a
233     subdirectory, which requires Meta-CVS to pick out the individual files
234     at the CVS level.
236     The tag, log, status and annotate commands are now available.
238     The MAP file is sorted on F- file names now, not path names. This
239     improves merging, since files do not move within the file when
240     they are renamed.
241 kaz 1.12
242 kaz 1.5 Release 0.3, 2002-02-02:
244 kaz 1.27 Process termination done is properly in top level handler, by a nonlocal
245     exit. The program properly indicates failed termination when it exits
246     due to an error condition.
248     Corrections are made in the command line option processing. If z is an
249     option that takes an argument, and the argument is -zx, then x is
250     treated as the argument to the option. Long options arguments are
251     recognized properly, according to the --opt=arg convention. The option
252     processing is restructured. Most of the commands now take the
253     appropriate cvs command-specific options.
255     The update algorithm performs dupe checking over the map, which could
256     happen during a merge.
258     Some more bugfixing has been done to the move command. It was still not
259     handling right some cases of an unversioned file being clobbered. Also,
260     it wasn't renaming a directory containing just one file.
262     I did some performance investigation for larger file sets, and
263     ended up rewriting the code that computes filesystem restructuring
264     changes and map duplicates.
265 kaz 1.5
266 kaz 1.4 Release 0.2, 2002-01-30:
268 kaz 1.27 Changed official name from MCVS to Meta-CVS. The move command now
269     performs some filesystem tests so it does the right thing when a versioned
270     file is moved over a non-versioned file, or when a file is moved into
271     a directory not known to Meta-CVS. Factored out reading and writing of
272     map files into functions.
273 kaz 1.4
274 kaz 1.2 Release 0.1, 2002-01-28:
276 kaz 1.27 Support for mcvs diff -u added. The -R option works for mcvs add command.
277     Bug fixed in mcvs mv command; it wasn't working analogously to the Unix
278     mv command when copying a directory to an existing directory.
279 kaz 1.2
280     Release 0.0, 2002-01-27:
281 kaz 1.1
282 kaz 1.27 This is alpha software. It is not complete, and lacks documentation.
283     However, it is already usable in its present state and is being used for
284     version control by its author. If you can program in Common Lisp and would
285     like to help, take a look through the TODO file. Send me patches, ideas,
286     feature requests.
