| NAME |
| ---- |
| git-archimport - Import an Arch repository into Git |
| |
| |
| SYNOPSIS |
| -------- |
| [verse] |
| 'git archimport' [-h] [-v] [-o] [-a] [-f] [-T] [-D depth] [-t tempdir] |
| <archive/branch>[:<git-branch>] ... |
| |
| DESCRIPTION |
| ----------- |
| 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 |
| import. |
| |
| '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 archimport'. |
| |
| 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{litdd}devo{litdd}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 periodically. |
| |
| |
| MERGES |
| ------ |
| 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 |
| ------- |
| |
| -h:: |
| Display usage. |
| |
| -v:: |
| Verbose output. |
| |
| -T:: |
| Many tags. Will create a tag for every commit, reflecting the commit |
| name in the Arch repository. |
| |
| -f:: |
| 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. |
| |
| -o:: |
| Use this for compatibility with old-style branch names used by |
| earlier versions of 'git archimport'. Old-style branch names |
| were category{litdd}branch, whereas new-style branch names are |
| archive,category{litdd}branch{litdd}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. |
| |
| -a:: |
| Attempt to auto-register archives at http://mirrors.sourcecontrol.net |
| This is particularly useful with the -D option. |
| |
| -t <tmpdir>:: |
| Override the default tempdir. |
| |
| |
| <archive/branch>:: |
| Archive/branch identifier in a format that `tla log` understands. |
