1git-archimport(1) 2================= 3 4NAME 5---- 6git-archimport - Import an Arch repository into git 7 8 9SYNOPSIS 10-------- 11[verse] 12'git archimport' [-h] [-v] [-o] [-a] [-f] [-T] [-D depth] [-t tempdir] 13 <archive/branch>[:<git-branch>] ... 14 15DESCRIPTION 16----------- 17Imports a project from one or more Arch repositories. It will follow branches 18and repositories within the namespaces defined by the <archive/branch> 19parameters supplied. If it cannot find the remote branch a merge comes from 20it will just import it as a regular commit. If it can find it, it will mark it 21as a merge whenever possible (see discussion below). 22 23The script expects you to provide the key roots where it can start the import 24from an 'initial import' or 'tag' type of Arch commit. It will follow and 25import new branches within the provided roots. 26 27It expects to be dealing with one project only. If it sees 28branches that have different roots, it will refuse to run. In that case, 29edit your <archive/branch> parameters to define clearly the scope of the 30import. 31 32'git archimport' uses `tla` extensively in the background to access the 33Arch repository. 34Make sure you have a recent version of `tla` available in the path. `tla` must 35know about the repositories you pass to 'git archimport'. 36 37For the initial import, 'git archimport' expects to find itself in an empty 38directory. To follow the development of a project that uses Arch, rerun 39'git archimport' with the same parameters as the initial import to perform 40incremental imports. 41 42While 'git archimport' will try to create sensible branch names for the 43archives that it imports, it is also possible to specify git branch names 44manually. To do so, write a git branch name after each <archive/branch> 45parameter, separated by a colon. This way, you can shorten the Arch 46branch names and convert Arch jargon to git jargon, for example mapping a 47"PROJECT--devo--VERSION" branch to "master". 48 49Associating multiple Arch branches to one git branch is possible; the 50result will make the most sense only if no commits are made to the first 51branch, after the second branch is created. Still, this is useful to 52convert Arch repositories that had been rotated periodically. 53 54 55MERGES 56------ 57Patch merge data from Arch is used to mark merges in git as well. git 58does not care much about tracking patches, and only considers a merge when a 59branch incorporates all the commits since the point they forked. The end result 60is that git will have a good idea of how far branches have diverged. So the 61import process does lose some patch-trading metadata. 62 63Fortunately, when you try and merge branches imported from Arch, 64git will find a good merge base, and it has a good chance of identifying 65patches that have been traded out-of-sequence between the branches. 66 67OPTIONS 68------- 69 70-h:: 71 Display usage. 72 73-v:: 74 Verbose output. 75 76-T:: 77 Many tags. Will create a tag for every commit, reflecting the commit 78 name in the Arch repository. 79 80-f:: 81 Use the fast patchset import strategy. This can be significantly 82 faster for large trees, but cannot handle directory renames or 83 permissions changes. The default strategy is slow and safe. 84 85-o:: 86 Use this for compatibility with old-style branch names used by 87 earlier versions of 'git archimport'. Old-style branch names 88 were category--branch, whereas new-style branch names are 89 archive,category--branch--version. In both cases, names given 90 on the command-line will override the automatically-generated 91 ones. 92 93-D <depth>:: 94 Follow merge ancestry and attempt to import trees that have been 95 merged from. Specify a depth greater than 1 if patch logs have been 96 pruned. 97 98-a:: 99 Attempt to auto-register archives at http://mirrors.sourcecontrol.net 100 This is particularly useful with the -D option. 101 102-t <tmpdir>:: 103 Override the default tempdir. 104 105 106<archive/branch>:: 107 Archive/branch identifier in a format that `tla log` understands. 108 109 110Author 111------ 112Written by Martin Langhoff <martin@catalyst.net.nz>. 113 114Documentation 115-------------- 116Documentation by Junio C Hamano, Martin Langhoff and the git-list <git@vger.kernel.org>. 117 118GIT 119--- 120Part of the linkgit:git[1] suite
