* checkout.lisp (mcvs-checkout): Don't delete the MCVS directory
of an existing checkout.
1 Release Notes for Meta-CVS
3 Release 0.17, 2002-07-??:
5 The create command no longer takes a vendor branch. Instead the symbol
6 ``Created-by-Meta-CVS'' is used as the vendor tag to satisfy CVS.
8 The grab command no longer does useless synchronization on files that
9 are about to be deleted.
11 New purge command, does ``cvs rm'' on deleted files; i.e. F- files that
12 have no mapping.
14 Bugfix: when a checkout bails because it is requested over top of an existing
15 working copy, it must not delete that working copy's MCVS sub directory.
17 Release 0.16, 2002-06-29:
19 Added new heuristics to grab command. Paths are analyzed to determine
20 move distance. Greater distances reduce the confidence in a move.
21 These rules help sort out grabs in a project where similar or
22 duplicate files are subject to parallel moves, the ambiguity being
23 resolved by favoring shorter moves. Word comparisons are case-insensitive
24 now. Common words (those that appear in many files) are ignored when
25 comparing files.
27 New options, --meta and --metaonly. This area of Meta-CVS is cleaned
28 up a little bit. Most reporting commands like log or diff no longer
29 operate on meta files by default; they must be explicitly told to do
30 so with --meta or --metaonly. Only the commit command implicitly includes
31 metafiles by default, and so if this is not wanted, --nometa must be
32 selected. The update command remains special; if it is given file
33 arguments, it does not include meta files. If given no arguments, it
34 does a global CVS up across the entire project.
36 Release 0.15, 2002-06-25:
38 Optimized a string splitting routine which is used heavily for processing
39 paths; the result is a noticeable performance improvement in some commands
40 that process large numbers of files.
42 Renamed ``import'' command to ``create''.
44 Bugfix: checkout and create showed errors when removing directory, due to
45 broken :postorder support in directory walking function.
47 Bugfix: on failure, checkout was failing to delete the MCVS directory when
48 the checkout was directed to an existing directory.
50 New feature: ``mcvs grab'' command imports third-party snapshots to a
51 branch. This is invoked in the root directory of the source tree to import.
52 It determines what files have been added and removed in the snapshot, and
53 tries to compute which removes and adds are actually moves. This is done by
54 analyzing the actual contents of the files according to a crude algorithm to
55 do fuzzy comparisons, so that even files which were modified as well as moved
56 are discovered.
58 Release 0.14, 2002-06-21:
60 Bugfix: mcvs add was broken for files that have no suffix, causing
61 the underlying cvs add to fail. This was broken in 0.7 when type
62 handling was added.
64 Release 0.13, 2002-06-06:
66 Sandbox synchronization now handles the case of two files having
67 the same timestamp. An error is signaled, with interactive resolution
68 to synchronize either way, or do nothing.
70 If a file must be deleted on update, and this cannot be done, it
71 is now a continuable error.
73 Bugfix: pass -I ! to cvs import so that it won't ignore some F- files
74 whose suffix is one of the ones cvs ignores by default.
76 New command: mcvs remap. The user can move or delete files directly without
77 going through Meta-CVS. When mcvs remap is invoked, it will hunt down the
78 moves and deletions, and reconstruct the mapping accordingly; that is,
79 it remaps the new structure. This command uses inode numbers to identify
80 files; if a file is copied and then the original is deleted, that won't
81 be recognized as a move.
83 Release 0.12, 2002-04-18:
85 Bugfix: remove was broken in 0.10, fixed now.
87 Bugfix: status, diff, etc. work in empty project rather than complaining
88 ``. not known to Meta-CVS''.
90 The checkout operation now can now populate an existing directory, including
91 the current working directory (mcvs co -d . modulename). Of course, the
92 target directory cannot be an existing Meta-CVS sandbox.
93 This is a useful feature, which allows sandboxes to blend with an
94 existing directory structure.
96 Checkout now uses the same function for generating the sandbox
97 structure as does update. This is now necessary, because local files
98 can be clobbered by the checkout.
100 Release 0.11, 2002-04-12:
102 Bugfix: when branch invokes rtag, it now takes the CVSROOT information
103 from CVS/Root and passes it via -d. This is necessary because rtag does not
104 look at a local CVS subdirectory for this information, only the
105 -d option or the environment variable.
107 Command for listing branches added (list-branches or lb). Also shows
108 what sticky tag the sandbox is updated to.
110 Command for switching branches added (switch or sw).
112 Merge detects that working copy is on non-branch tag and bails.
114 Absolute paths can now be specified as file arguments. These are
115 based from the root directory of the sandbox, not the actual filesystem root
116 directory.
118 Release 0.10, 2002-04-03:
120 Automatic merging implemented. Branch is created using branch command,
121 and merging from another branch is done using simple merge command.
122 Meta-CVS maintains the tags to keep track of what has been merged
123 from what branch to what branch.
125 Bugfix: checkout -d foo bar was complaining about directory bar already
126 existing, even though it should only care about foo.
128 The remove command now requires explicit -R option to recursively remove
129 a directory. It has more detailed error reporting.
131 The move command has better error reporting.
133 Release 0.9, 2002-03-14:
135 Bugfix: the .cvsignore file is now subject to tagging, status, etc,
136 (unless --nometa is specified, of course).
138 The mcvs filt command takes -r <revision> or -D <date> parameters.
139 This means to retrieve the MAP file as of the specified revision or
140 date and use that mapping to perform the filtering translation,
141 rather than using MAP-LOCAL.
143 The mcvs update command takes filename arguments now and also
144 supports the -p option.
146 Release 0.8, 2002-03-13:
148 Bug fixed in mcvs add; it was not ignoring files that are already
149 listed as :ignore in MCVS/TYPES.
151 Bug fixed in mcvs move: a target with a trailing slash is now treated
152 as a directory (if it does not already exist and is a non-directory).
154 The -d option of mcvs checkout can now be used to override the checkout
155 directory, which is normally the same as the module name.
157 The global options --version, --help, -q, -Q and -e are now supported.
159 New global options --error-continue and --error-terminate to disable
160 interactive error handling in two different ways.
162 Log level of many messages has changed; many messages have been
163 relegated to debug level.
165 The import command now creates a .cvsignore file containing the name
168 Release 0.7, 2002-03-09:
170 The import command collects a list of the file suffixes and brings up
171 a text editor to allow the user to edit their CVS keyword expansion
172 behavior. This information is kept in a new metafile called TYPES. The
173 add command also updates TYPES; it identifies any suffixes which are new,
174 and brings up an editor. The F- files now carry suffixes, which
175 simplifies interfacing with CVS, and also allows cvswrappers to work.
177 Recursive add works (mcvs add -R ...).
179 New command line option --nometa allows metafiles to be excluded from
180 diff, tag, and other commands; without the option they are inserted
181 into the list of files to be processed.
183 The commit option now takes an optional list of files or directories,
184 just like tag, diff, and others.
186 Release 0.6, 2002-02-16:
188 The add operation was horribly broken in 0.5, it is fixed.
190 User can interactively select whether to clobber local files or leave
191 everything alone. Effects on the mapping file of a mcvs move are undone,
192 if the restructuring is rolled back, or raises a condition that leads
193 to termination.
195 Meta-CVS now keeps a new meta-file called MCVS/TYPES. This is created
196 during import, and specifies the CVS keyword expansion mode for files
197 having given suffixes, and can also tell Meta-CVS to ignore certain files
198 when importing or adding.
200 Release 0.5, 2002-02-10:
202 Much improved error handling. Filesystem rearranging code performs
203 sanity checks to prevent adds and moves from accidentally clobbering
204 local files. A rearranging gone bad can be rolled back. Effects
205 of a failed mcvs add can also be rolled back.
207 MAP-LOCAL is now sorted in the same way as MAP.
209 Release 0.4, 2002-02-04:
211 CVS is invoked using internal function resembling the xargs utility,
212 which ensures that multiple command lines are generated if necessary to
213 avoid surpassing the operating system limit on argument and environment
214 vector size. This is important when someone wants to diff or stat a
215 subdirectory, which requires Meta-CVS to pick out the individual files
216 at the CVS level.
218 The tag, log, status and annotate commands are now available.
220 The MAP file is sorted on F- file names now, not path names. This
221 improves merging, since files do not move within the file when
222 they are renamed.
224 Release 0.3, 2002-02-02:
226 Process termination done is properly in top level handler, by a nonlocal
227 exit. The program properly indicates failed termination when it exits
228 due to an error condition.
230 Corrections are made in the command line option processing. If z is an
231 option that takes an argument, and the argument is -zx, then x is
232 treated as the argument to the option. Long options arguments are
233 recognized properly, according to the --opt=arg convention. The option
234 processing is restructured. Most of the commands now take the
235 appropriate cvs command-specific options.
237 The update algorithm performs dupe checking over the map, which could
238 happen during a merge.
240 Some more bugfixing has been done to the move command. It was still not
241 handling right some cases of an unversioned file being clobbered. Also,
242 it wasn't renaming a directory containing just one file.
244 I did some performance investigation for larger file sets, and
245 ended up rewriting the code that computes filesystem restructuring
246 changes and map duplicates.
248 Release 0.2, 2002-01-30:
250 Changed official name from MCVS to Meta-CVS. The move command now
251 performs some filesystem tests so it does the right thing when a versioned
252 file is moved over a non-versioned file, or when a file is moved into
253 a directory not known to Meta-CVS. Factored out reading and writing of
254 map files into functions.
256 Release 0.1, 2002-01-28:
258 Support for mcvs diff -u added. The -R option works for mcvs add command.
259 Bug fixed in mcvs mv command; it wasn't working analogously to the Unix
260 mv command when copying a directory to an existing directory.
262 Release 0.0, 2002-01-27:
264 This is alpha software. It is not complete, and lacks documentation.
265 However, it is already usable in its present state and is being used for
266 version control by its author. If you can program in Common Lisp and would
267 like to help, take a look through the TODO file. Send me patches, ideas,
268 feature requests.
