6 git-cvsserver - A CVS server emulator for git
11 export CVS_SERVER=git-cvsserver
12 'cvs' -d :ext:user@server/path/repo.git co <HEAD_name>
17 This application is a CVS emulation layer for git.
19 It is highly functional. However, not all methods are implemented,
20 and for those methods that are implemented,
21 not all switches are implemented.
23 Testing has been done using both the CLI CVS client, and the Eclipse CVS
24 plugin. Most functionality works fine with both of these clients.
29 Currently cvsserver works over SSH connections for read/write clients, and
30 over pserver for anonymous CVS access.
32 CVS clients cannot tag, branch or perform GIT merges.
37 1. If you are going to offer anonymous CVS access via pserver, add a line in
40 cvspserver stream tcp nowait nobody git-cvsserver pserver
42 Note: In some cases, you need to pass the 'pserver' argument twice for
43 git-cvsserver to see it. So the line would look like
45 cvspserver stream tcp nowait nobody git-cvsserver pserver pserver
47 No special setup is needed for SSH access, other than having GIT tools
48 in the PATH. If you have clients that do not accept the CVS_SERVER
49 env variable, you can rename git-cvsserver to cvs.
51 2. For each repo that you want accessible from CVS you need to edit config in
52 the repo and add the following section.
56 # optional for debugging
57 logfile=/path/to/logfile
59 Note: you need to ensure each user that is going to invoke git-cvsserver has
60 write access to the log file and to the git repository. When offering anon
61 access via pserver, this means that the nobody user should have write access
62 to at least the sqlite database at the root of the repository.
64 3. On the client machine you need to set the following variables.
65 CVSROOT should be set as per normal, but the directory should point at the
66 appropriate git repo. For example:
68 For SSH access, CVS_SERVER should be set to git-cvsserver
72 export CVSROOT=:ext:user@server:/var/git/project.git
73 export CVS_SERVER=git-cvsserver
75 4. For SSH clients that will make commits, make sure their .bashrc file
76 sets the GIT_AUTHOR and GIT_COMMITTER variables.
78 5. Clients should now be able to check out the project. Use the CVS 'module'
79 name to indicate what GIT 'head' you want to check out. Example:
81 cvs co -d project-master master
83 Eclipse CVS Client Notes
84 ------------------------
86 To get a checkout with the Eclipse CVS client:
88 1. Select "Create a new project -> From CVS checkout"
89 2. Create a new location. See the notes below for details on how to choose the
91 3. Browse the 'modules' available. It will give you a list of the heads in
92 the repository. You will not be able to browse the tree from there. Only
94 4. Pick 'HEAD' when it asks what branch/tag to check out. Untick the
95 "launch commit wizard" to avoid committing the .project file.
97 Protocol notes: If you are using anonymous acces via pserver, just select that.
98 Those using SSH access should choose the 'ext' protocol, and configure 'ext'
99 access on the Preferences->Team->CVS->ExtConnection pane. Set CVS_SERVER to
100 'git-cvsserver'. Not that password support is not good when using 'ext',
101 you will definitely want to have SSH keys setup.
103 Alternatively, you can just use the non-standard extssh protocol that Eclipse
104 offer. In that case CVS_SERVER is ignored, and you will have to replace
105 the cvs utility on the server with git-cvsserver or manipulate your .bashrc
106 so that calling 'cvs' effectively calls git-cvsserver.
108 Clients known to work
109 ---------------------
112 CVS 1.11.17 on MacOSX (from Fink package)
113 Eclipse 3.0, 3.1.2 on MacOSX (see Eclipse CVS Client Notes)
119 All the operations required for normal use are supported, including
120 checkout, diff, status, update, log, add, remove, commit.
121 Legacy monitoring operations are not supported (edit, watch and related).
122 Exports and tagging (tags and branches) are not supported at this stage.
124 The server will set the -k mode to binary when relevant. In proper GIT
125 tradition, the contents of the files are always respected.
126 No keyword expansion or newline munging is supported.
131 git-cvsserver depends on DBD::SQLite.
