Branch: MAIN
Changes since 1.63: +3 -0 lines
* checkout.lisp (mcvs-checkout): New key parameter, no-generate.
Tells the checkout function not to unpack the MCVS directory.
This will be useful when mcvs-checkout is used as a subfunction
of the new grab command. Failed CVS call is now turned into
an error. The MCVS subdirectory is *always* deleted, even if the
checkout did not create the checkout directory.
1 Release Notes for Meta-CVS
2
3 Release 0.15, 2002-??-??:
4
5 Optimized a string splitting routine which is used heavily for
6 processing paths; the result is a noticeable performance improvement
7 in some commands that process large numbers of files.
8
9 Renamed ``import'' command to ``create''.
10
11 Bugfix: checkout and create showed errors when removing directory,
12 due to broken :postorder support in directory walking function.
13
14 Bugfix: on failure, checkout was failing to delete the MCVS directory
15 when the checkout was directed to an existing directory.
16
17 Release 0.14, 2002-06-21:
18
19 Bugfix: mcvs add was broken for files that have no suffix, causing
20 the underlying cvs add to fail. This was broken in 0.7 when type
21 handling was added.
22
23 Release 0.13, 2002-06-06:
24
25 Sandbox synchronization now handles the case of two files having
26 the same timestamp. An error is signaled, with interactive resolution
27 to synchronize either way, or do nothing.
28
29 If a file must be deleted on update, and this cannot be done, it
30 is now a continuable error.
31
32 Bugfix: pass -I ! to cvs import so that it won't ignore some F- files
33 whose suffix is one of the ones cvs ignores by default.
34
35 New command: mcvs remap. The user can move or delete files directly without
36 going through Meta-CVS. When mcvs remap is invoked, it will hunt down the
37 moves and deletions, and reconstruct the mapping accordingly; that is,
38 it remaps the new structure. This command uses inode numbers to identify
39 files; if a file is copied and then the original is deleted, that won't
40 be recognized as a move.
41
42 Release 0.12, 2002-04-18:
43
44 Bugfix: remove was broken in 0.10, fixed now.
45
46 Bugfix: status, diff, etc. work in empty project rather than complaining
47 ``. not known to Meta-CVS''.
48
49 The checkout operation now can now populate an existing directory, including
50 the current working directory (mcvs co -d . modulename). Of course, the
51 target directory cannot be an existing Meta-CVS sandbox.
52 This is a useful feature, which allows sandboxes to blend with an
53 existing directory structure.
54
55 Checkout now uses the same function for generating the sandbox
56 structure as does update. This is now necessary, because local files
57 can be clobbered by the checkout.
58
59 Release 0.11, 2002-04-12:
60
61 Bugfix: when branch invokes rtag, it now takes the CVSROOT information
62 from CVS/Root and passes it via -d. This is necessary because rtag does not
63 look at a local CVS subdirectory for this information, only the
64 -d option or the environment variable.
65
66 Command for listing branches added (list-branches or lb). Also shows
67 what sticky tag the sandbox is updated to.
68
69 Command for switching branches added (switch or sw).
70
71 Merge detects that working copy is on non-branch tag and bails.
72
73 Absolute paths can now be specified as file arguments. These are
74 based from the root directory of the sandbox, not the actual filesystem root
75 directory.
76
77 Release 0.10, 2002-04-03:
78
79 Automatic merging implemented. Branch is created using branch command,
80 and merging from another branch is done using simple merge command.
81 Meta-CVS maintains the tags to keep track of what has been merged
82 from what branch to what branch.
83
84 Bugfix: checkout -d foo bar was complaining about directory bar already
85 existing, even though it should only care about foo.
86
87 The remove command now requires explicit -R option to recursively remove
88 a directory. It has more detailed error reporting.
89
90 The move command has better error reporting.
91
92 Release 0.9, 2002-03-14:
93
94 Bugfix: the .cvsignore file is now subject to tagging, status, etc,
95 (unless --nometa is specified, of course).
96
97 The mcvs filt command takes -r <revision> or -D <date> parameters.
98 This means to retrieve the MAP file as of the specified revision or
99 date and use that mapping to perform the filtering translation,
100 rather than using MAP-LOCAL.
101
102 The mcvs update command takes filename arguments now and also
103 supports the -p option.
104
105 Release 0.8, 2002-03-13:
106
107 Bug fixed in mcvs add; it was not ignoring files that are already
108 listed as :ignore in MCVS/TYPES.
109
110 Bug fixed in mcvs move: a target with a trailing slash is now treated
111 as a directory (if it does not already exist and is a non-directory).
112
113 The -d option of mcvs checkout can now be used to override the checkout
114 directory, which is normally the same as the module name.
115
116 The global options --version, --help, -q, -Q and -e are now supported.
117
118 New global options --error-continue and --error-terminate to disable
119 interactive error handling in two different ways.
120
121 Log level of many messages has changed; many messages have been
122 relegated to debug level.
123
124 The import command now creates a .cvsignore file containing the name
125 MAP-LOCAL.
126
127 Release 0.7, 2002-03-09:
128
129 The import command collects a list of the file suffixes and brings up
130 a text editor to allow the user to edit their CVS keyword expansion
131 behavior. This information is kept in a new metafile called TYPES. The
132 add command also updates TYPES; it identifies any suffixes which are new,
133 and brings up an editor. The F- files now carry suffixes, which
134 simplifies interfacing with CVS, and also allows cvswrappers to work.
135
136 Recursive add works (mcvs add -R ...).
137
138 New command line option --nometa allows metafiles to be excluded from
139 diff, tag, and other commands; without the option they are inserted
140 into the list of files to be processed.
141
142 The commit option now takes an optional list of files or directories,
143 just like tag, diff, and others.
144
145 Release 0.6, 2002-02-16:
146
147 The add operation was horribly broken in 0.5, it is fixed.
148
149 User can interactively select whether to clobber local files or leave
150 everything alone. Effects on the mapping file of a mcvs move are undone,
151 if the restructuring is rolled back, or raises a condition that leads
152 to termination.
153
154 Meta-CVS now keeps a new meta-file called MCVS/TYPES. This is created
155 during import, and specifies the CVS keyword expansion mode for files
156 having given suffixes, and can also tell Meta-CVS to ignore certain files
157 when importing or adding.
158
159 Release 0.5, 2002-02-10:
160
161 Much improved error handling. Filesystem rearranging code performs
162 sanity checks to prevent adds and moves from accidentally clobbering
163 local files. A rearranging gone bad can be rolled back. Effects
164 of a failed mcvs add can also be rolled back.
165
166 MAP-LOCAL is now sorted in the same way as MAP.
167
168 Release 0.4, 2002-02-04:
169
170 CVS is invoked using internal function resembling the xargs utility,
171 which ensures that multiple command lines are generated if necessary to
172 avoid surpassing the operating system limit on argument and environment
173 vector size. This is important when someone wants to diff or stat a
174 subdirectory, which requires Meta-CVS to pick out the individual files
175 at the CVS level.
176
177 The tag, log, status and annotate commands are now available.
178
179 The MAP file is sorted on F- file names now, not path names. This
180 improves merging, since files do not move within the file when
181 they are renamed.
182
183 Release 0.3, 2002-02-02:
184
185 Process termination done is properly in top level handler, by a nonlocal
186 exit. The program properly indicates failed termination when it exits
187 due to an error condition.
188
189 Corrections are made in the command line option processing. If z is an
190 option that takes an argument, and the argument is -zx, then x is
191 treated as the argument to the option. Long options arguments are
192 recognized properly, according to the --opt=arg convention. The option
193 processing is restructured. Most of the commands now take the
194 appropriate cvs command-specific options.
195
196 The update algorithm performs dupe checking over the map, which could
197 happen during a merge.
198
199 Some more bugfixing has been done to the move command. It was still not
200 handling right some cases of an unversioned file being clobbered. Also,
201 it wasn't renaming a directory containing just one file.
202
203 I did some performance investigation for larger file sets, and
204 ended up rewriting the code that computes filesystem restructuring
205 changes and map duplicates.
206
207 Release 0.2, 2002-01-30:
208
209 Changed official name from MCVS to Meta-CVS. The move command now
210 performs some filesystem tests so it does the right thing when a versioned
211 file is moved over a non-versioned file, or when a file is moved into
212 a directory not known to Meta-CVS. Factored out reading and writing of
213 map files into functions.
214
215 Release 0.1, 2002-01-28:
216
217 Support for mcvs diff -u added. The -R option works for mcvs add command.
218 Bug fixed in mcvs mv command; it wasn't working analogously to the Unix
219 mv command when copying a directory to an existing directory.
220
221 Release 0.0, 2002-01-27:
222
223 This is alpha software. It is not complete, and lacks documentation.
224 However, it is already usable in its present state and is being used for
225 version control by its author. If you can program in Common Lisp and would
226 like to help, take a look through the TODO file. Send me patches, ideas,
227 feature requests.
