git-fast-export(1)
==================
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 'git fast-import'.
You can use it as a human-readable bundle replacement (see
linkgit:git-bundle[1]), or as a kind of an interactive
'git filter-branch'.
OPTIONS
-------
--progress=<n>::
Insert 'progress' statements every <n> objects, to be shown by
'git fast-import' 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.
--tag-of-filtered-object=(abort|drop|rewrite)::
Specify how to handle tags whose tagged object is filtered out.
Since revisions and files to export can be limited by path,
tagged objects may be filtered completely.
+
When asking to 'abort' (which is the default), this program will die
when encountering such a tag. With 'drop' it will omit such tags from
the output. With 'rewrite', if the tagged object is a commit, it will
rewrite the tag to tag an ancestor commit (via parent rewriting; see
linkgit:git-rev-list[1])
-M::
-C::
Perform move and/or copy detection, as described in the
linkgit:git-diff[1] manual page, and use it to generate
rename and copy commands in the output dump.
+
Note that earlier versions of this command did not complain and
produced incorrect results if you gave these options.
--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.
--fake-missing-tagger::
Some old repositories have tags without a tagger. The
fast-import protocol was pretty strict about that, and did not
allow that. So fake a tagger to be able to fast-import the
output.
--no-data::
Skip output of blob objects and instead refer to blobs via
their original SHA-1 hash. This is useful when rewriting the
directory structure or history of a repository without
touching the contents of individual files. Note that the
resulting stream can only be used by a repository which
already contains the necessary objects.
--full-tree::
This option will cause fast-export to issue a "deleteall"
directive for each commit followed by a full list of all files
in the commit (as opposed to just listing the files which are
different from the commit's first parent).
[git-rev-list-args...]::
A list of arguments, acceptable to 'git rev-parse' and
'git rev-list', that specifies the specific objects and references
to export. For example, `master\~10..master` causes the
current master reference to be exported along with all objects
added since its 10th ancestor commit.
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 'git fast-import' 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.
