1git-cvsserver(1) 2================ 3 4NAME 5---- 6git-cvsserver - A CVS server emulator for git 7 8SYNOPSIS 9-------- 10[verse] 11export CVS_SERVER=git-cvsserver 12'cvs' -d :ext:user@server/path/repo.git co <HEAD_name> 13 14DESCRIPTION 15----------- 16 17This application is a CVS emulation layer for git. 18 19It is highly functional. However, not all methods are implemented, 20and for those methods that are implemented, 21not all switches are implemented. 22 23Testing has been done using both the CLI CVS client, and the Eclipse CVS 24plugin. Most functionality works fine with both of these clients. 25 26LIMITATIONS 27----------- 28 29Currently cvsserver works over SSH connections for read/write clients, and 30over pserver for anonymous CVS access. 31 32CVS clients cannot tag, branch or perform GIT merges. 33 34INSTALLATION 35------------ 36 371. If you are going to offer anonymous CVS access via pserver, add a line in 38 /etc/inetd.conf like 39 40 cvspserver stream tcp nowait nobody git-cvsserver pserver 41 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 44 45 cvspserver stream tcp nowait nobody git-cvsserver pserver pserver 46 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. 50 512. For each repo that you want accessible from CVS you need to edit config in 52 the repo and add the following section. 53 54 [gitcvs] 55 enabled=1 56 # optional for debugging 57 logfile=/path/to/logfile 58 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. 63 643. 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: 67 68 For SSH access, CVS_SERVER should be set to git-cvsserver 69 70 Example: 71 72 export CVSROOT=:ext:user@server:/var/git/project.git 73 export CVS_SERVER=git-cvsserver 74 754. For SSH clients that will make commits, make sure their .bashrc file 76 sets the GIT_AUTHOR and GIT_COMMITTER variables. 77 785. 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: 80 81 cvs co -d project-master master 82 83Eclipse CVS Client Notes 84------------------------ 85 86To get a checkout with the Eclipse CVS client: 87 881. Select "Create a new project -> From CVS checkout" 892. Create a new location. See the notes below for details on how to choose the 90 right protocol. 913. 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 93 the heads. 944. Pick 'HEAD' when it asks what branch/tag to check out. Untick the 95 "launch commit wizard" to avoid committing the .project file. 96 97Protocol notes: If you are using anonymous acces via pserver, just select that. 98Those using SSH access should choose the 'ext' protocol, and configure 'ext' 99access on the Preferences->Team->CVS->ExtConnection pane. Set CVS_SERVER to 100'git-cvsserver'. Not that password support is not good when using 'ext', 101you will definitely want to have SSH keys setup. 102 103Alternatively, you can just use the non-standard extssh protocol that Eclipse 104offer. In that case CVS_SERVER is ignored, and you will have to replace 105the cvs utility on the server with git-cvsserver or manipulate your .bashrc 106so that calling 'cvs' effectively calls git-cvsserver. 107 108Clients known to work 109--------------------- 110 111CVS 1.12.9 on Debian 112CVS 1.11.17 on MacOSX (from Fink package) 113Eclipse 3.0, 3.1.2 on MacOSX (see Eclipse CVS Client Notes) 114TortoiseCVS 115 116Operations supported 117-------------------- 118 119All the operations required for normal use are supported, including 120checkout, diff, status, update, log, add, remove, commit. 121Legacy monitoring operations are not supported (edit, watch and related). 122Exports and tagging (tags and branches) are not supported at this stage. 123 124The server will set the -k mode to binary when relevant. In proper GIT 125tradition, the contents of the files are always respected. 126No keyword expansion or newline munging is supported. 127 128Dependencies 129------------ 130 131git-cvsserver depends on DBD::SQLite. 132 133Copyright and Authors 134--------------------- 135 136This program is copyright The Open University UK - 2006. 137 138Authors: Martyn Smith <martyn@catalyst.net.nz> 139 Martin Langhoff <martin@catalyst.net.nz> 140 with ideas and patches from participants of the git-list <git@vger.kernel.org>. 141 142Documentation 143-------------- 144Documentation by Martyn Smith <martyn@catalyst.net.nz> and Martin Langhoff <martin@catalyst.net.nz> Matthias Urlichs <smurf@smurf.noris.de>. 145 146GIT 147--- 148Part of the gitlink:git[7] suite
