Dumps the internal marks table to <file> when complete.

Marks are written one per line as <code>:markid</code> <code>SHA-1</code>. 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.

In addition to labelling blobs and commits with mark ids, also

label tags. This is useful in conjunction with

|
<code>--export-marks</code> and <code>--import-marks</code>, and is also useful (and
|
|
necessary) for exporting of nested tags. It does not hurt
|
|
other cases and would be the default, but many fast-import

|
frontends are not prepared to accept tags with mark
|
|
identifiers.

|
|
<div class="paragraph"><p>Any commits (or tags) that have already been marked will not be

exported again. If the backend uses a similar --import-marks file,

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.

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

By default, running a command such as <code>git</code> <code>fast-export</code>

<code>master~5</code><code>..</code><code>master</code> will not include the commit master~5
|
|
and will make master~4 no longer have master~5 as

a parent (though both the old master~4 and new
|
|
master~4 will have all the same files). Use
|
|
--reference-excluded-parents to instead have the stream
|
|
refer to commits in the excluded range of history by their
|
|
sha1sum. Note that the resulting stream can only be used by a

Add an extra directive to the output for commits and blobs,

<code>original-oid</code> <em><SHA1SUM></em>. While such directives will likely be

ignored by importers such as git-fast-import, it may be useful

for intermediary filters (e.g. for rewriting commit messages

collapse "User 0", "User 1", etc into "User X"). This produces a much

smaller output, and it is usually easy to quickly confirm that there is

no private data in the stream.</p></div>

<div class="paragraph"><p>Reproducing some bugs may require referencing particular commits or
|
|
paths, which becomes challenging after refnames and paths have been
|
|
anonymized. You can ask for a particular token to be left as-is or
|
|
mapped to a new value. For example, if you have a bug which reproduces
|
|
with <code>git</code> <code>rev-list</code> <code>sensitive</code> <code>--</code> <code>secret.c</code>, you can run:</p></div>
|
|
<div class="listingblock">
|
|
<div class="content">
|
|
<pre><code>$ git fast-export --anonymize --all \
|
|
--anonymize-map=sensitive:foo \
|
|
--anonymize-map=secret.c:bar.c \
|
|
>stream</code></pre>
|
|
</div></div>
|
|
<div class="paragraph"><p>After importing the stream, you can then run <code>git</code> <code>rev-list</code> <code>foo</code> <code>--</code> <code>bar.c</code>
|
|
in the anonymized repository.</p></div>
|
|
<div class="paragraph"><p>Note that paths and refnames are split into tokens at slash boundaries.
|
|
The command above would anonymize <code>subdir/secret.c</code> as something like
|
|
<code>path123/bar.c</code>; you could then search for <code>bar.c</code> in the anonymized
|
|
repository to determine the final pathname.</p></div>
|
|
<div class="paragraph"><p>To make referencing the final pathname simpler, you can map each path
|
|
component; so if you also anonymize <code>subdir</code> to <code>publicdir</code>, then the
|
|
final pathname would be <code>publicdir/bar.c</code>.</p></div>
