1 Release Notes for Meta-CVS
2
3 Release 0.17, 2002-07-??:
4
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.
7
8 The grab command no longer does useless synchronization on files that
9 are about to be deleted.
10
11 New purge command, does ``cvs rm'' on deleted files; i.e. F- files that
12 have no mapping.
13
14 Release 0.16, 2002-06-29:
15
16 Added new heuristics to grab command. Paths are analyzed to determine
17 move distance. Greater distances reduce the confidence in a move.
18 These rules help sort out grabs in a project where similar or
19 duplicate files are subject to parallel moves, the ambiguity being
20 resolved by favoring shorter moves. Word comparisons are case-insensitive
21 now. Common words (those that appear in many files) are ignored when
22 comparing files.
23
24 New options, --meta and --metaonly. This area of Meta-CVS is cleaned
25 up a little bit. Most reporting commands like log or diff no longer
26 operate on meta files by default; they must be explicitly told to do
27 so with --meta or --metaonly. Only the commit command implicitly includes
28 metafiles by default, and so if this is not wanted, --nometa must be
29 selected. The update command remains special; if it is given file
30 arguments, it does not include meta files. If given no arguments, it
31 does a global CVS up across the entire project.
32
33 Release 0.15, 2002-06-25:
34
35 Optimized a string splitting routine which is used heavily for processing
36 paths; the result is a noticeable performance improvement in some commands
37 that process large numbers of files.
38
39 Renamed ``import'' command to ``create''.
40
41 Bugfix: checkout and create showed errors when removing directory, due to
42 broken :postorder support in directory walking function.
43
44 Bugfix: on failure, checkout was failing to delete the MCVS directory when
45 the checkout was directed to an existing directory.
46
47 New feature: ``mcvs grab'' command imports third-party snapshots to a
48 branch. This is invoked in the root directory of the source tree to import.
49 It determines what files have been added and removed in the snapshot, and
50 tries to compute which removes and adds are actually moves. This is done by
51 analyzing the actual contents of the files according to a crude algorithm to
52 do fuzzy comparisons, so that even files which were modified as well as moved
53 are discovered.
54
55 Release 0.14, 2002-06-21:
56
57 Bugfix: mcvs add was broken for files that have no suffix, causing
58 the underlying cvs add to fail. This was broken in 0.7 when type
59 handling was added.
60
61 Release 0.13, 2002-06-06:
62
63 Sandbox synchronization now handles the case of two files having
64 the same timestamp. An error is signaled, with interactive resolution
65 to synchronize either way, or do nothing.
66
67 If a file must be deleted on update, and this cannot be done, it
68 is now a continuable error.
69
70 Bugfix: pass -I ! to cvs import so that it won't ignore some F- files
71 whose suffix is one of the ones cvs ignores by default.
72
73 New command: mcvs remap. The user can move or delete files directly without
74 going through Meta-CVS. When mcvs remap is invoked, it will hunt down the
75 moves and deletions, and reconstruct the mapping accordingly; that is,
76 it remaps the new structure. This command uses inode numbers to identify
77 files; if a file is copied and then the original is deleted, that won't
78 be recognized as a move.
79
80 Release 0.12, 2002-04-18:
81
82 Bugfix: remove was broken in 0.10, fixed now.
83
84 Bugfix: status, diff, etc. work in empty project rather than complaining
85 ``. not known to Meta-CVS''.
86
87 The checkout operation now can now populate an existing directory, including
88 the current working directory (mcvs co -d . modulename). Of course, the
89 target directory cannot be an existing Meta-CVS sandbox.
90 This is a useful feature, which allows sandboxes to blend with an
91 existing directory structure.
92
93 Checkout now uses the same function for generating the sandbox
94 structure as does update. This is now necessary, because local files
95 can be clobbered by the checkout.
96
97 Release 0.11, 2002-04-12:
98
99 Bugfix: when branch invokes rtag, it now takes the CVSROOT information
100 from CVS/Root and passes it via -d. This is necessary because rtag does not
101 look at a local CVS subdirectory for this information, only the
102 -d option or the environment variable.
103
104 Command for listing branches added (list-branches or lb). Also shows
105 what sticky tag the sandbox is updated to.
106
107 Command for switching branches added (switch or sw).
108
109 Merge detects that working copy is on non-branch tag and bails.
110
111 Absolute paths can now be specified as file arguments. These are
112 based from the root directory of the sandbox, not the actual filesystem root
113 directory.
114
115 Release 0.10, 2002-04-03:
116
117 Automatic merging implemented. Branch is created using branch command,
118 and merging from another branch is done using simple merge command.
119 Meta-CVS maintains the tags to keep track of what has been merged
120 from what branch to what branch.
121
122 Bugfix: checkout -d foo bar was complaining about directory bar already
123 existing, even though it should only care about foo.
124
125 The remove command now requires explicit -R option to recursively remove
126 a directory. It has more detailed error reporting.
127
128 The move command has better error reporting.
129
130 Release 0.9, 2002-03-14:
131
132 Bugfix: the .cvsignore file is now subject to tagging, status, etc,
133 (unless --nometa is specified, of course).
134
135 The mcvs filt command takes -r <revision> or -D <date> parameters.
136 This means to retrieve the MAP file as of the specified revision or
137 date and use that mapping to perform the filtering translation,
138 rather than using MAP-LOCAL.
139
140 The mcvs update command takes filename arguments now and also
141 supports the -p option.
142
143 Release 0.8, 2002-03-13:
144
145 Bug fixed in mcvs add; it was not ignoring files that are already
146 listed as :ignore in MCVS/TYPES.
147
148 Bug fixed in mcvs move: a target with a trailing slash is now treated
149 as a directory (if it does not already exist and is a non-directory).
150
151 The -d option of mcvs checkout can now be used to override the checkout
152 directory, which is normally the same as the module name.
153
154 The global options --version, --help, -q, -Q and -e are now supported.
155
156 New global options --error-continue and --error-terminate to disable
157 interactive error handling in two different ways.
158
159 Log level of many messages has changed; many messages have been
160 relegated to debug level.
161
162 The import command now creates a .cvsignore file containing the name
163 MAP-LOCAL.
164
165 Release 0.7, 2002-03-09:
166
167 The import command collects a list of the file suffixes and brings up
168 a text editor to allow the user to edit their CVS keyword expansion
169 behavior. This information is kept in a new metafile called TYPES. The
170 add command also updates TYPES; it identifies any suffixes which are new,
171 and brings up an editor. The F- files now carry suffixes, which
172 simplifies interfacing with CVS, and also allows cvswrappers to work.
173
174 Recursive add works (mcvs add -R ...).
175
176 New command line option --nometa allows metafiles to be excluded from
177 diff, tag, and other commands; without the option they are inserted
178 into the list of files to be processed.
179
180 The commit option now takes an optional list of files or directories,
181 just like tag, diff, and others.
182
183 Release 0.6, 2002-02-16:
184
185 The add operation was horribly broken in 0.5, it is fixed.
186
187 User can interactively select whether to clobber local files or leave
188 everything alone. Effects on the mapping file of a mcvs move are undone,
189 if the restructuring is rolled back, or raises a condition that leads
190 to termination.
191
192 Meta-CVS now keeps a new meta-file called MCVS/TYPES. This is created
193 during import, and specifies the CVS keyword expansion mode for files
194 having given suffixes, and can also tell Meta-CVS to ignore certain files
195 when importing or adding.
196
197 Release 0.5, 2002-02-10:
198
199 Much improved error handling. Filesystem rearranging code performs
200 sanity checks to prevent adds and moves from accidentally clobbering
201 local files. A rearranging gone bad can be rolled back. Effects
202 of a failed mcvs add can also be rolled back.
203
204 MAP-LOCAL is now sorted in the same way as MAP.
205
206 Release 0.4, 2002-02-04:
207
208 CVS is invoked using internal function resembling the xargs utility,
209 which ensures that multiple command lines are generated if necessary to
210 avoid surpassing the operating system limit on argument and environment
211 vector size. This is important when someone wants to diff or stat a
212 subdirectory, which requires Meta-CVS to pick out the individual files
213 at the CVS level.
214
215 The tag, log, status and annotate commands are now available.
216
217 The MAP file is sorted on F- file names now, not path names. This
218 improves merging, since files do not move within the file when
219 they are renamed.
220
221 Release 0.3, 2002-02-02:
222
223 Process termination done is properly in top level handler, by a nonlocal
224 exit. The program properly indicates failed termination when it exits
225 due to an error condition.
226
227 Corrections are made in the command line option processing. If z is an
228 option that takes an argument, and the argument is -zx, then x is
229 treated as the argument to the option. Long options arguments are
230 recognized properly, according to the --opt=arg convention. The option
231 processing is restructured. Most of the commands now take the
232 appropriate cvs command-specific options.
233
234 The update algorithm performs dupe checking over the map, which could
235 happen during a merge.
236
237 Some more bugfixing has been done to the move command. It was still not
238 handling right some cases of an unversioned file being clobbered. Also,
239 it wasn't renaming a directory containing just one file.
240
241 I did some performance investigation for larger file sets, and
242 ended up rewriting the code that computes filesystem restructuring
243 changes and map duplicates.
244
245 Release 0.2, 2002-01-30:
246
247 Changed official name from MCVS to Meta-CVS. The move command now
248 performs some filesystem tests so it does the right thing when a versioned
249 file is moved over a non-versioned file, or when a file is moved into
250 a directory not known to Meta-CVS. Factored out reading and writing of
251 map files into functions.
252
253 Release 0.1, 2002-01-28:
254
255 Support for mcvs diff -u added. The -R option works for mcvs add command.
256 Bug fixed in mcvs mv command; it wasn't working analogously to the Unix
257 mv command when copying a directory to an existing directory.
258
259 Release 0.0, 2002-01-27:
260
261 This is alpha software. It is not complete, and lacks documentation.
262 However, it is already usable in its present state and is being used for
263 version control by its author. If you can program in Common Lisp and would
264 like to help, take a look through the TODO file. Send me patches, ideas,
265 feature requests.
