1 Release Notes for Meta-CVS
2
3 Release 0.10, 2002-04-??:
4
5 Automatic merging implemented. Branch is created using branch command,
6 and merging from another branch is done using simple merge command.
7 Meta-CVS maintains the tags to keep track of what has been merged
8 from what branch to what branch.
9
10 Bugfix: checkout -d foo bar was complaining about directory bar already
11 existing, even though it should only care about foo.
12
13 The remove command now requires explicit -R option to recursively remove
14 a directory. It has more detailed error reporting.
15
16 The move command has better error reporting.
17
18 Release 0.9, 2002-03-14:
19
20 Bugfix: the .cvsignore file is now subject to tagging, status, etc,
21 (unless --nometa is specified, of course).
22
23 The mcvs filt command takes -r <revision> or -D <date> parameters.
24 This means to retrieve the MAP file as of the specified revision or
25 date and use that mapping to perform the filtering translation,
26 rather than using MAP-LOCAL.
27
28 The mcvs update command takes filename arguments now and also
29 supports the -p option.
30
31 Release 0.8, 2002-03-13:
32
33 Bug fixed in mcvs add; it was not ignoring files that are already
34 listed as :ignore in MCVS/TYPES.
35
36 Bug fixed in mcvs move: a target with a trailing slash is now treated
37 as a directory (if it does not already exist and is a non-directory).
38
39 The -d option of mcvs checkout can now be used to override the checkout
40 directory, which is normally the same as the module name.
41
42 The global options --version, --help, -q, -Q and -e are now supported.
43
44 New global options --error-continue and --error-terminate to disable
45 interactive error handling in two different ways.
46
47 Log level of many messages has changed; many messages have been
48 relegated to debug level.
49
50 The import command now creates a .cvsignore file containing the name
51 MAP-LOCAL.
52
53 Release 0.7, 2002-03-09:
54
55 The import command collects a list of the file suffixes and brings up
56 a text editor to allow the user to edit their CVS keyword expansion
57 behavior. This information is kept in a new metafile called TYPES. The
58 add command also updates TYPES; it identifies any suffixes which are new,
59 and brings up an editor. The F- files now carry suffixes, which
60 simplifies interfacing with CVS, and also allows cvswrappers to work.
61
62 Recursive add works (mcvs add -R ...).
63
64 New command line option --nometa allows metafiles to be excluded from
65 diff, tag, and other commands; without the option they are inserted
66 into the list of files to be processed.
67
68 The commit option now takes an optional list of files or directories,
69 just like tag, diff, and others.
70
71 Release 0.6, 2002-02-16:
72
73 The add operation was horribly broken in 0.5, it is fixed.
74
75 User can interactively select whether to clobber local files or leave
76 everything alone. Effects on the mapping file of a mcvs move are undone,
77 if the restructuring is rolled back, or raises a condition that leads
78 to termination.
79
80 Meta-CVS now keeps a new meta-file called MCVS/TYPES. This is created
81 during import, and specifies the CVS keyword expansion mode for files
82 having given suffixes, and can also tell Meta-CVS to ignore certain files
83 when importing or adding.
84
85 Release 0.5, 2002-02-10:
86
87 Much improved error handling. Filesystem rearranging code performs
88 sanity checks to prevent adds and moves from accidentally clobbering
89 local files. A rearranging gone bad can be rolled back. Effects
90 of a failed mcvs add can also be rolled back.
91
92 MAP-LOCAL is now sorted in the same way as MAP.
93
94 Release 0.4, 2002-02-04:
95
96 CVS is invoked using internal function resembling the xargs utility,
97 which ensures that multiple command lines are generated if necessary to
98 avoid surpassing the operating system limit on argument and environment
99 vector size. This is important when someone wants to diff or stat a
100 subdirectory, which requires Meta-CVS to pick out the individual files
101 at the CVS level.
102
103 The tag, log, status and annotate commands are now available.
104
105 The MAP file is sorted on F- file names now, not path names. This
106 improves merging, since files do not move within the file when
107 they are renamed.
108
109 Release 0.3, 2002-02-02:
110
111 Process termination done is properly in top level handler, by a nonlocal
112 exit. The program properly indicates failed termination when it exits
113 due to an error condition.
114
115 Corrections are made in the command line option processing. If z is an
116 option that takes an argument, and the argument is -zx, then x is
117 treated as the argument to the option. Long options arguments are
118 recognized properly, according to the --opt=arg convention. The option
119 processing is restructured. Most of the commands now take the
120 appropriate cvs command-specific options.
121
122 The update algorithm performs dupe checking over the map, which could
123 happen during a merge.
124
125 Some more bugfixing has been done to the move command. It was still not
126 handling right some cases of an unversioned file being clobbered. Also,
127 it wasn't renaming a directory containing just one file.
128
129 I did some performance investigation for larger file sets, and
130 ended up rewriting the code that computes filesystem restructuring
131 changes and map duplicates.
132
133 Release 0.2, 2002-01-30:
134
135 Changed official name from MCVS to Meta-CVS. The move command now
136 performs some filesystem tests so it does the right thing when a versioned
137 file is moved over a non-versioned file, or when a file is moved into
138 a directory not known to Meta-CVS. Factored out reading and writing of
139 map files into functions.
140
141 Release 0.1, 2002-01-28:
142
143 Support for mcvs diff -u added. The -R option works for mcvs add command.
144 Bug fixed in mcvs mv command; it wasn't working analogously to the Unix
145 mv command when copying a directory to an existing directory.
146
147 Release 0.0, 2002-01-27:
148
149 This is alpha software. It is not complete, and lacks documentation.
150 However, it is already usable in its present state and is being used for
151 version control by its author. If you can program in Common Lisp and would
152 like to help, take a look through the TODO file. Send me patches, ideas,
153 feature requests.
