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{tilde}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. |
