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
42 cvspserver stream tcp nowait nobody git-cvsserver pserver
45 Note: In some cases, you need to pass the 'pserver' argument twice for
46 git-cvsserver to see it. So the line would look like
49 cvspserver stream tcp nowait nobody git-cvsserver pserver pserver
52 No special setup is needed for SSH access, other than having GIT tools
53 in the PATH. If you have clients that do not accept the CVS_SERVER
54 env variable, you can rename git-cvsserver to cvs.
56 2. For each repo that you want accessible from CVS you need to edit config in
57 the repo and add the following section.
63 # optional for debugging
64 logfile=/path/to/logfile
67 Note: you need to ensure each user that is going to invoke git-cvsserver has
68 write access to the log file and to the git repository. When offering anon
69 access via pserver, this means that the nobody user should have write access
70 to at least the sqlite database at the root of the repository.
72 3. On the client machine you need to set the following variables.
73 CVSROOT should be set as per normal, but the directory should point at the
74 appropriate git repo. For example:
77 For SSH access, CVS_SERVER should be set to git-cvsserver
82 export CVSROOT=:ext:user@server:/var/git/project.git
83 export CVS_SERVER=git-cvsserver
86 4. For SSH clients that will make commits, make sure their .bashrc file
87 sets the GIT_AUTHOR and GIT_COMMITTER variables.
89 5. Clients should now be able to check out the project. Use the CVS 'module'
90 name to indicate what GIT 'head' you want to check out. Example:
93 cvs co -d project-master master
96 Eclipse CVS Client Notes
97 ------------------------
99 To get a checkout with the Eclipse CVS client:
101 1. Select "Create a new project -> From CVS checkout"
102 2. Create a new location. See the notes below for details on how to choose the
104 3. Browse the 'modules' available. It will give you a list of the heads in
105 the repository. You will not be able to browse the tree from there. Only
107 4. Pick 'HEAD' when it asks what branch/tag to check out. Untick the
108 "launch commit wizard" to avoid committing the .project file.
110 Protocol notes: If you are using anonymous access via pserver, just select that.
111 Those using SSH access should choose the 'ext' protocol, and configure 'ext'
112 access on the Preferences->Team->CVS->ExtConnection pane. Set CVS_SERVER to
113 'git-cvsserver'. Not that password support is not good when using 'ext',
114 you will definitely want to have SSH keys setup.
116 Alternatively, you can just use the non-standard extssh protocol that Eclipse
117 offer. In that case CVS_SERVER is ignored, and you will have to replace
118 the cvs utility on the server with git-cvsserver or manipulate your .bashrc
119 so that calling 'cvs' effectively calls git-cvsserver.
121 Clients known to work
122 ---------------------
125 CVS 1.11.17 on MacOSX (from Fink package)
126 Eclipse 3.0, 3.1.2 on MacOSX (see Eclipse CVS Client Notes)
132 All the operations required for normal use are supported, including
133 checkout, diff, status, update, log, add, remove, commit.
134 Legacy monitoring operations are not supported (edit, watch and related).
135 Exports and tagging (tags and branches) are not supported at this stage.
137 The server will set the -k mode to binary when relevant. In proper GIT
138 tradition, the contents of the files are always respected.
139 No keyword expansion or newline munging is supported.
144 git-cvsserver depends on DBD::SQLite.
