"git am -3" first tries to apply the patch without any extra trick, and
applies it to a synthesized tree for 3-way merge after the first attempt
fails. "git apply" exits with status 1 for a patch that is well-formed
but is not applicable (and it dies on other errors with non-zereo, non-1
status) and has an optimization to fall back to the 3-way merge only in
the case.
An earlier patch 3ddd170 (am: suppress apply errors when using 3-way,
2009-06-16) squelched diagnostic messages from the first attempt, not to
be shown to the end user. This worked reasonably well if the reason the
first application failed was because the patch was made against a wrong
version.
When the patch is corrupt (e.g. line-wrapped or leading whitespaces got
dropped), however, because the second patch application is not even
attempted, the error message from the first application is never shown
and is forever lost. This message is necessary to locate where the patch
is corrupt and fix it up.
We could fix this issue by reverting 3dd170, or keeping the error message
to somewhere and showing it, but because this is an error codepath, the
easiest is to disable the optimization. The second patch application is
attempted even when the input is corrupt, and it will notice, diagnose,
and stop with an error message.

We have to deal with two separate code paths: a normal rebase, which
actually goes through git-am; and rebase {-m|-s}.
The only small issue with both is that they need to remember the
original sha1 across a possible conflict resolution. rebase -m
already puts this information in $dotest/current, and we just
introduce a similar file for git-am.
Note that in git-am, the hook really only runs when coming from
git-rebase: the code path that sets the $dotest/original-commit file
is guarded by a test for $dotest/rebasing.

c2ca1d7 (Allow mailsplit (and hence git-am) to handle mails with CRLF
line-endings, 2009-08-04) fixed "git mailsplit" to help people with
MUA whose output from save-as command uses CRLF as line terminators by
stripping CR at the end of lines.
However, when you know you are feeding output from "git format-patch"
directly to "git am", and especially when your contents have CR at the

- If $GIT_PAGER is set to the empty string, instead of passing

Ever since the initial implementation, "git am" had kept a dead code that
never triggered due to a typo in the variable name. Worse yet, the code,
if it weren't for the typo, would have attempted to add "[PATCH] " at the
beginning of the Subject: header when "git am" is run with its "-k"
option. However, because "git am -k" tells mailinfo to keep such prefix
when parsing the input, the "[PATCH] " added by this dead code would have
really been unnecessary duplicate.
Embarrassing is that we kept _maintaining_ the codepath without anybody
noticing for four years.

If the user has exported the GREP_OPTIONS environment variable, the output
from "grep" and "egrep" in scripted Porcelains may be different from what
they expect. For example, we may want to count number of matching lines,
by "grep" piped to "wc -l", and GREP_OPTIONS=-C3 will break such use.
The approach taken by this change to address this issue is to protect only
our own use of grep/egrep. Because we do not unset it at the beginning of
our scripts, hook scripts run from the scripted Porcelains are exposed to
the same insanity this environment variable causes when grep/egrep is used
to implement logic (e.g. "grep | wc -l"), and it is entirely up to the
hook scripts to protect themselves.
On the other hand, applypatch-msg hook may want to show offending words in
the proposed commit log message using grep to the end user, and the user
might want to set GREP_OPTIONS=--color to paint the match more visibly.
The approach to protect only our own use without unsetting the environment
variable globally will allow this use case.

We traditionally allowed a mbox file or a directory name of a maildir (but
never an individual file inside a maildir) to be given to "git am". Even
though an individual file in a maildir (or more generally, a piece of
RFC2822 e-mail) is not a mbox file, it contains enough information to
create a commit out of it, so there is no reason to reject one. Running
mailsplit on such a file feels stupid, but it does not hurt.
This builds on top of a5a6755 (git-am foreign patch support: introduce
patch_format, 2009-05-27) that introduced mailbox format detection. The
codepath to deal with a mbox requires it to begin with "From " line and
also allows it to begin with "From: ", but a random piece of e-mail can
and often do begin with any valid RFC2822 header lines.
Instead of checking the first line, we extract all the lines up to the
first empty line, and make sure they look like e-mail headers.

Traditionally git-rebase was implemented in terms of "format-patch" piped
to "am -3", to strike balance between speed (because it avoids a rather
expensive read-tree/merge-recursive machinery most of the time) and
flexibility (the magic "-3" allows it to fall back to 3-way merge as
necessary). However, this combination has one flaw when dealing with a
nonstandard commit log message format that has more than one lines in the
first paragraph.
This teaches "git am --rebasing" to take advantage of the fact that the

object name, to get the log message from the original commit object
instead.

This reverts commit 6e9e0327b7. People
can prepare a text file with Subject: and From: headers and feed it to

When you have a file called HEAD in your work tree, many commands that
our scripts feed "HEAD" to would complain about the rev vs path
ambiguity. A solution is to form command line more carefully by
appending -- to them, which makes it clear that we mean HEAD rev not
HEAD file.

git-am used "git apply -z --index-info" to find the original versions
of the files touched by the diff, to be able to do an inexpensive
three-way merge.
This operation makes only sense in a repository, since the index

Therefore, teach "git apply" a mode to write out the result as an

A lot of shell scripts contained stuff starting with
while case "$#" in 0) break ;; esac
and similar. I consider breaking out of the condition instead of the
body od the loop ugly, and the implied "true" value of the
non-matching case is not really obvious to humans at first glance. It
happens not to be obvious to some BSD shells, either, but that's
because they are not POSIX-compliant. In most cases, this has been
replaced by a straight condition using "test". "case" has the
advantage of being faster than "test" on vintage shells where "test"
is not a builtin. Since none of them is likely to run the git
scripts, anyway, the added readability should be worth the change.
A few loops have had their termination condition expressed
differently.

Earlier, "git rerere" was enabled by creating the directory
.git/rr-cache. That is definitely not in line with most other
features, which are enabled by a config variable.
So, check the config variable "rerere.enabled". If it is set
to "false" explicitely, do not activate rerere, even if
.git/rr-cache exists. This should help when you want to disable
rerere temporarily.
If "rerere.enabled" is not set at all, fall back to detection
of the directory .git/rr-cache.

Under some implementations of echo (such as that provided by

I am working on a project that required parsing through regular
mboxes that didn't necessarily have patches embedded in them. I
started by creating my own modified copy of git-am and working
from there. Very quickly, I noticed git-mailinfo wasn't able to
handle a big chunk of my email.
After hacking up numerous solutions and running into more
limitations, I decided it was just easier to rewrite a big chunk
of it. The following patch has a bunch of fixes and features
that I needed in order for me do what I wanted.
Note: I'm didn't follow any email rfc papers but I don't think
any of the changes I did required much knowledge (besides the
boundary stuff).
List of major changes/fixes:
- can't create empty patch files fix
- empty patch files don't fail, this failure will come inside git-am
- multipart boundaries are now handled
- only output inbody headers if a patch exists otherwise assume those
headers are part of the reply and instead output the original headers
- decode and filter base64 patches correctly
- various other accidental fixes
I believe I didn't break any existing functionality or
compatibility (other than what I describe above, which is really
only the empty patch file).
I tested this through various mailing list archives and
everything seemed to parse correctly (a couple thousand emails).

Junio rightly pointed out that the --reflog-action parameter
was starting to get out of control, as most porcelain code
needed to hand it to other porcelain and plumbing alike to
ensure the reflog contained the top-level user action and
not the lower-level actions it invoked.
At Junio's suggestion we are introducing the new set_reflog_action
function to all shell scripts, allowing them to declare early on
what their default reflog name should be, but this setting only
takes effect if the caller has not already set the GIT_REFLOG_ACTION
environment variable.

Data in rr-cache isn't valid after a patch application is

as a resolution of that skipped/failed commit, which is wrong.

An earlier commit cbd64af added a check that prevents "git-am"
to run without its standard input connected to a terminal while
resuming operation. This was to catch a user error to try
feeding a new patch from its standard input while recovery.
The assumption of the check was that it is an indication that a
new patch is being fed if the standard input is not connected to
a terminal. It is however not quite correct (the standard input
can be /dev/null if the user knows the operation does not need
any input, for example). This broke t3403 when the test was run
with its standard input connected to /dev/null.
When git-am is given an explicit command such as --skip, there
is no reason to insist that the standard input is a terminal; we
are not going to read a new patch anyway.
Credit goes to Gerrit Pape for noticing and reporting the
problem with t3403-rebase-skip test.

In a workflow that employs relatively long lived topic branches,
the developer sometimes needs to resolve the same conflict over
and over again until the topic branches are done (either merged
to the "release" branch, or sent out and accepted upstream).
This commit introduces a new command, "git rerere", to help this
process by recording the conflicted automerge results and
corresponding hand-resolve results on the initial manual merge,
and later by noticing the same conflicted automerge and applying
the previously recorded hand resolution using three-way merge.

git-am --skip does not unpack the next patch and ends up reapplying the
old patch, believing that it is the new patch in the sequence.
If the old patch applied successfully it will commit it with the
supposedly skipped log message and ends up dropping the following patch.
If the patch did not apply the user is left with the conflict he tried
to skip and has to unpack the next patch in the sequence by hand to get
git-am back on track.
By clearing the resume variable whenever skips bumps the sequence
counter we correctly unpack the next patch. I also added another
resume= in the case a patch file is missing from the sequence to
avoid the same problem when a file in the sequence was removed.
