By default, running a command such as `git fast-export

smaller output, and it is usually easy to quickly confirm that there is
no private data in the stream.
+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 `git rev-list sensitive -- secret.c`, you can run:
+
+---------------------------------------------------
+$ git fast-export --anonymize --all \
+ --anonymize-map=sensitive:foo \
+ --anonymize-map=secret.c:bar.c \
+ >stream
+---------------------------------------------------
+
+After importing the stream, you can then run `git rev-list foo -- bar.c`
+in the anonymized repository.
+
+Note that paths and refnames are split into tokens at slash boundaries.
+The command above would anonymize `subdir/secret.c` as something like
+`path123/bar.c`; you could then search for `bar.c` in the anonymized
+repository to determine the final pathname.
+
+To make referencing the final pathname simpler, you can map each path
+component; so if you also anonymize `subdir` to `publicdir`, then the
+final pathname would be `publicdir/bar.c`.

+ref-transaction
+~~~~~~~~~~~~~~~
+
+This hook is invoked by any Git command that performs reference
+updates. It executes whenever a reference transaction is prepared,
+committed or aborted and may thus get called multiple times.
+
+The hook takes exactly one argument, which is the current state the
+given reference transaction is in:
+
+ - "prepared": All reference updates have been queued to the
+ transaction and references were locked on disk.
+
+ - "committed": The reference transaction was committed and all
+ references now have their respective new value.
+
+ - "aborted": The reference transaction was aborted, no changes
+ were performed and the locks have been released.
+
+For each reference update that was added to the transaction, the hook
+receives on standard input a line of the format:
+
+ <old-value> SP <new-value> SP <ref-name> LF
+
+The exit status of the hook is ignored for any state except for the
+"prepared" state. In the "prepared" state, a non-zero exit status will
+cause the transaction to be aborted. The hook will not be called with
+"aborted" state in that case.

Linus was the maintainer and I was a contributor, when you look

branch being the "contributor" branch. Your work started at the
tip of the "maintainer" branch some time ago, you made a lot of
progress in the meantime, and now the maintainer branch has some
other commits you do not have yet. And "git rebase" was written
with the explicit purpose of helping to maintain branches like
-"pu". You _could_ merge master to pu and keep going, but if you

eventually want to cherrypick and merge some but not necessarily
all changes back to the master branch, it often makes later
operations for _you_ easier if you rebase (i.e. carry forward
-your changes) "pu" rather than merge. So I ran "git rebase":

- $ git checkout pu
- $ git rebase master pu

What this does is to pick all the commits since the current
-branch (note that I now am on "pu" branch) forked from the

master branch, and forward port these changes.

The diff between master^ and #1 is applied to master and

anymore, so after doing this you will have dangling commit if

can run "git prune" to get rid of those original three commits.
While I am talking about "git rebase", I should talk about how
break building Git with GCC 2.95. While they were well-intentioned
portability fixes, keeping things working with gcc-2.95 was also
important. Here is what I did to revert the change in the 'master'
-branch and to adjust the 'pu' branch, using core Git tools and

barebone Porcelain.

+
+The server can advertise the `object-format` capability with a value `X` (in the

+SHA-1, it should specify its object-format string.
