This adds the --import-marks and --export-marks to fast-export. These import and export the marks used to for all revisions exported in a similar fashion to what fast-import does. The format is the same as fast-import, so you can create a bidirectional importer / exporter by using the same marks file on both sides.

NAME
|
|
----
|
|
git-fast-export - Git data exporter
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
'git-fast-export [options]' | 'git-fast-import'
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
This program dumps the given revisions in a form suitable to be piped
|
|
into linkgit:git-fast-import[1].
|
|
|
|
You can use it as a human readable bundle replacement (see
|
|
linkgit:git-bundle[1]), or as a kind of an interactive
|
|
linkgit:git-filter-branch[1].
|
|
|
|
|
|
OPTIONS
|
|
-------
|
|
--progress=<n>::
|
|
Insert 'progress' statements every <n> objects, to be shown by
|
|
linkgit:git-fast-import[1] during import.
|
|
|
|
--signed-tags=(verbatim|warn|strip|abort)::
|
|
Specify how to handle signed tags. Since any transformation
|
|
after the export can change the tag names (which can also happen
|
|
when excluding revisions) the signatures will not match.
|
|
+
|
|
When asking to 'abort' (which is the default), this program will die
|
|
when encountering a signed tag. With 'strip', the tags will be made
|
|
unsigned, with 'verbatim', they will be silently exported
|
|
and with 'warn', they will be exported, but you will see a warning.
|
|
|
|
--export-marks=<file>::
|
|
Dumps the internal marks table to <file> when complete.
|
|
Marks are written one per line as `:markid SHA-1`. Only marks
|
|
for revisions are dumped; marks for blobs are ignored.
|
|
Backends can use this file to validate imports after they
|
|
have been completed, or to save the marks table across
|
|
incremental runs. As <file> is only opened and truncated
|
|
at completion, the same path can also be safely given to
|
|
\--import-marks.
|
|
|
|
--import-marks=<file>::
|
|
Before processing any input, load the marks specified in
|
|
<file>. The input file must exist, must be readable, and
|
|
must use the same format as produced by \--export-marks.
|
|
+
|
|
Any commits that have already been marked will not be exported again.
|
|
If the backend uses a similar \--import-marks file, this allows for
|
|
incremental bidirectional exporting of the repository by keeping the
|
|
marks the same across runs.
|
|
|
|
|
|
EXAMPLES
|
|
--------
|
|
|
|
-------------------------------------------------------------------
|
|
$ git fast-export --all | (cd /empty/repository && git fast-import)
|
|
-------------------------------------------------------------------
|
|
|
|
This will export the whole repository and import it into the existing
|
|
empty repository. Except for reencoding commits that are not in
|
|
UTF-8, it would be a one-to-one mirror.
|
|
|
|
-----------------------------------------------------
|
|
$ git fast-export master~5..master |
|
|
sed "s|refs/heads/master|refs/heads/other|" |
|
|
git fast-import
|
|
-----------------------------------------------------
|
|
|
|
This makes a new branch called 'other' from 'master~5..master'
|
|
(i.e. if 'master' has linear history, it will take the last 5 commits).
|
|
|
|
Note that this assumes that none of the blobs and commit messages
|
|
referenced by that revision range contains the string
|
|
'refs/heads/master'.
|
|
|
|
|
|
Limitations
|
|
-----------
|
|
|
|
Since linkgit:git-fast-import[1] cannot tag trees, you will not be
|
|
able to export the linux-2.6.git repository completely, as it contains
|
|
a tag referencing a tree instead of a commit.
