NAME         top

       git-archimport - Import an Arch repository into Git

SYNOPSIS         top

       git archimport [-h] [-v] [-o] [-a] [-f] [-T] [-D depth] [-t tempdir]
                      <archive/branch>[:<git-branch>] ...

DESCRIPTION         top

       Imports a project from one or more Arch repositories. It will follow
       branches and repositories within the namespaces defined by the
       <archive/branch> parameters supplied. If it cannot find the remote
       branch a merge comes from it will just import it as a regular commit.
       If it can find it, it will mark it as a merge whenever possible (see
       discussion below).

       The script expects you to provide the key roots where it can start
       the import from an initial import or tag type of Arch commit. It will
       follow and import new branches within the provided roots.

       It expects to be dealing with one project only. If it sees branches
       that have different roots, it will refuse to run. In that case, edit
       your <archive/branch> parameters to define clearly the scope of the

       git archimport uses tla extensively in the background to access the
       Arch repository. Make sure you have a recent version of tla available
       in the path. tla must know about the repositories you pass to git

       For the initial import, git archimport expects to find itself in an
       empty directory. To follow the development of a project that uses
       Arch, rerun git archimport with the same parameters as the initial
       import to perform incremental imports.

       While git archimport will try to create sensible branch names for the
       archives that it imports, it is also possible to specify Git branch
       names manually. To do so, write a Git branch name after each
       <archive/branch> parameter, separated by a colon. This way, you can
       shorten the Arch branch names and convert Arch jargon to Git jargon,
       for example mapping a "PROJECT--devo--VERSION" branch to "master".

       Associating multiple Arch branches to one Git branch is possible; the
       result will make the most sense only if no commits are made to the
       first branch, after the second branch is created. Still, this is
       useful to convert Arch repositories that had been rotated

MERGES         top

       Patch merge data from Arch is used to mark merges in Git as well. Git
       does not care much about tracking patches, and only considers a merge
       when a branch incorporates all the commits since the point they
       forked. The end result is that Git will have a good idea of how far
       branches have diverged. So the import process does lose some
       patch-trading metadata.

       Fortunately, when you try and merge branches imported from Arch, Git
       will find a good merge base, and it has a good chance of identifying
       patches that have been traded out-of-sequence between the branches.

OPTIONS         top

           Display usage.

           Verbose output.

           Many tags. Will create a tag for every commit, reflecting the
           commit name in the Arch repository.

           Use the fast patchset import strategy. This can be significantly
           faster for large trees, but cannot handle directory renames or
           permissions changes. The default strategy is slow and safe.

           Use this for compatibility with old-style branch names used by
           earlier versions of git archimport. Old-style branch names were
           category--branch, whereas new-style branch names are
           archive,category--branch--version. In both cases, names given on
           the command-line will override the automatically-generated ones.

       -D <depth>
           Follow merge ancestry and attempt to import trees that have been
           merged from. Specify a depth greater than 1 if patch logs have
           been pruned.

           Attempt to auto-register archives at
  This is particularly useful with
           the -D option.

       -t <tmpdir>
           Override the default tempdir.

           Archive/branch identifier in a format that tla log understands.
