6b4b013f18 mailinfo: handle in-body header continuations
Mailinfo currently handles multi-line headers, but it does not handle
multi-line in-body headers. Teach it to handle such headers, for
example, for this input:

  From: author <author@example.com>
  Date: Fri, 9 Jun 2006 00:44:16 -0700
  Subject: a very long
   broken line

  Subject: another very long
   broken line

interpret the in-body subject to be "another very long broken line"
instead of "another very long".

An existing test (t/t5100/msg0015) has an indented line immediately
after an in-body header - it has been modified to reflect the new
functionality.

d6a2b05cbb Merge branch 'jc/builtin-am-signoff-regression-fix'
Recent "git am" had regression when adding a Signed-off-by line
with its "-s" option by an unintended tightening of how an existing
trailer block is detected.

aab845424e am: match --signoff to the original scripted version
Linus noticed that the recently reimplemented "git am -s" defines
the trailer block too rigidly, resulting in an unnecessary blank
line between the existing sign-offs and his new sign-off.  An e-mail
submission sent to Linus in real life ends with mixture of sign-offs
and commentaries, e.g.

	title here

	message here

	Signed-off-by: Original Author <original@auth.or>
	[rv: tweaked frotz and nitfol]
	Signed-off-by: Re Viewer <rv@ew.er>
	Signed-off-by: Other Reviewer <other@rev.ewer>
	---
	patch here

Because the reimplementation reused append_signoff() helper that is
used by other codepaths, which is unaware that people intermix such
comments with their sign-offs in the trailer block, such a message
was judged to end with a non-trailer, resulting in an extra blank
line before adding a new sign-off.

The original scripted version of "git am" used a lot looser
definition, i.e. "if and only if there is no line that begins with
Signed-off-by:, add a blank line before adding a new sign-off".  For
the upcoming release, stop using the append_signoff() in "git am"
and reimplement the looser definition used by the scripted version
to use only in "git am" to fix this regression in "am" while
avoiding new regressions to other users of append_signoff().

In the longer term, we should look into loosening append_signoff()
so that other codepaths that add a new sign-off behave the same way
as "git am -s", but that is a task for post-release.

9dd330e6ca rerere: release lockfile in non-writing functions
There's a bug in builtin/am.c in which we take a lock on
MERGE_RR recursively. But rather than fix am.c, this patch
fixes the confusing interface from rerere.c that caused the
bug. Read on for the gory details.

The setup_rerere() function both reads the existing MERGE_RR
file, and takes MERGE_RR.lock. In the rerere() and
rerere_forget() functions, we end up in write_rr(), which
will then commit the lock file.

But for functions like rerere_clear() that do not write to
MERGE_RR, we expect the caller to have handled
setup_rerere(). That caller would then need to release the
lockfile, but it can't; the lock struct is local to
rerere.c.

For builtin/rerere.c, this is OK. We run a single rerere
operation and then exit immediately, which has the side
effect of rolling back the lockfile.

But in builtin/am.c, this is actively wrong. If we run "git
am -3 --skip", we call setup-rerere twice without releasing
the lock:

  1. The "--skip" causes us to call am_rerere_clear(), which
     calls setup_rerere(), but never drops the lock.

  2. We then proceed to the next patch.

  3. The "--3way" may cause us to call rerere() to handle
     conflicts in that patch, but we are already holding the
     lock. The lockfile code dies with:

     BUG: prepare_tempfile_object called for active object

We could fix this by having rerere_clear() call
rollback_lock_file(). But it feels a bit odd for it to roll
back a lockfile that it did not itself take. So let's
simplify the interface further, and handle setup_rerere in
the function itself, taking away the question from the
caller over whether they need to do so.

We can give rerere_gc() the same treatment, as well (even
though it doesn't have any callers besides builtin/rerere.c
at this point). Note that these functions don't take flags
from their callers to pass along to setup_rerere; that's OK,
because the flags would not be meaningful for what they are
doing.

Both of those functions need to hold the lock because even
though they do not write to MERGE_RR, they are still writing
and should be protected from a simultaneous "rerere" run.
But rerere_remaining(), "rerere diff", and "rerere status"
are all read-only operations. They want to setup_rerere(),
but do not care about taking the lock in the first place.
Since our update of MERGE_RR is the usual atomic rename done
by commit_lock_file, they can just do a lockless read. For
that, we teach setup_rerere a READONLY flag to avoid the
lock.

As a bonus, this pushes builtin/rerere.c's setup_rerere call
closer to the functions that use it. Which means that "git
rerere totally-bogus-command" will no longer silently
exit(0) in a repository without rerere enabled.

e9dfe253fd am: use gmtime() to parse mercurial patch date
An example of the line in a mercurial patch that specifies the date of
the commit would be:

	# Date 1433753301 25200

where the first number is the number of seconds since the unix epoch (in
UTC), and the second number is the offset of the timezone, in second s
west of UTC (negative if the timezone is east of UTC).

git-am uses localtime() to break down the first number into its
components (year, month, day, hours, minutes, seconds etc.). However,
the returned components are relative to the user's time zone. As a
result, if the user's time zone does not match the time zone specified
in the patch, the resulting commit will have the wrong author date.

Fix this by using gmtime() instead, which uses UTC instead of the user's
time zone.

b141f3c9d3 am: handle stray $dotest directory
The following bug has been observed:

  $ git am  # no input file
  ^C
  $ git am --abort
  Resolve operation not in progress, we are not resuming.

This happens because the following test fails:

  test -d "$dotest" && test -f "$dotest/last" && test -f "$dotest/next"

and the codepath for an "am in-progress" is not executed.  It falls back
to the codepath that treats this as a "fresh execution".  Before
rr/rebase-autostash, this condition was

  test -d "$dotest"

It would incorrectly execute the "normal" am --abort codepath:

  git read-tree --reset -u HEAD ORIG_HEAD
  git reset ORIG_HEAD

by incorrectly assuming that an am is "in progress" (i.e. ORIG_HEAD
etc. was written during the previous execution).

Notice that

  $ git am
  ^C

executes nothing of significance, is equivalent to

  $ mkdir .git/rebase-apply

Therefore, the correct solution is to treat .git/rebase-apply as a
"stray directory" and remove it on --abort in the fresh-execution
codepath.  Also ensure that we're not called with --rebasing from
git-rebase--am.sh; in that case, it is the responsibility of the caller
to handle and stray directories.

While at it, tell the user to run "git am --abort" to get rid of the
stray $dotest directory, if she attempts anything else.

250b3c6c99 apply --whitespace=fix: avoid running over the postimage buffer
Originally update-pre-post-images could assume that any whitespace
fixing will make the result only shorter by unexpanding runs of
leading SPs into HTs and removing trailing whitespaces at the end of
lines.  Updating the post-image we read from the patch to match the
actual result can be performed in-place under this assumption.
These days, however, we have tab-in-indent (aka Python) rule whose
result can be longer than the original, and we do need to allocate
a larger buffer than the input and replace the result.

Fortunately the support for lengthening rewrite was already added
when we began supporting "match while ignoring whitespace
differences" mode in 86c91f9179 (git apply: option to ignore
whitespace differences, 2009-08-04).  We only need to correctly
count the number of bytes necessary to hold the updated result and
tell the function to allocate a new buffer.

the patch to guess its format, but would go into an infinite loop
when the patch file happened to be empty.  The solution: exit the
loop when "read" fails, not when the line var, "$l1" becomes empty.

1f5ad6b1a7 t: use sane_unset instead of unset
Change several tests to use the sane_unset function introduced in
v1.7.3.1-35-g00648ba instead of the built-in unset function.

This fixes a failure I was having on t9130-git-svn-authors-file.sh on
Solaris, and prevents several other issues from occurring.

ee2d1cb402 mailinfo: with -b, keep space after [foo]
The logic for the -b mode, where [PATCH] is dropped but [foo] is not,
silently ate all spaces after the ].

Fix this by keeping the next isspace() character, if there is any.
Being more thorough is pointless, as the later cleanup_space() call
will normalize any sequence of whitespace to a single ' '.

f7e5ea171b am: learn passing -b to mailinfo
git-am could pass -k to mailinfo, but not -b.  Introduce an option
that does so.  We change the meaning of the 'keep' state file, but are
careful not to cause a problem unless you downgrade in the middle of
an 'am' run.

This uncovers a bug in mailinfo -b, hence the failing test.

0e8341f29d am: ignore leading whitespace before patch
Some web-based email clients prepend whitespace to raw message
transcripts to workaround content-sniffing in some browsers.  Adjust
the patch format detection logic to ignore leading whitespace.

So now you can apply patches from GMail with "git am" in three steps:

 1. choose "show original"
 2. tell the browser to "save as" (for example by pressing Ctrl+S)
 3. run "git am" on the saved file

This fixes a regression introduced by v1.6.4-rc0~15^2~2 (git-am
foreign patch support: autodetect some patch formats, 2009-05-27).
GMail support was first introduced to "git am" by v1.5.4-rc0~274^2
(Make mailsplit and mailinfo strip whitespace from the start of the
input, 2007-11-01).

Breaks in a test assertion's && chain can potentially hide
failures from earlier commands in the chain.

Commands intended to fail should be marked with !, test_must_fail, or
test_might_fail.  The examples in this patch do not require that.

18cdf802ca Teach "apply --index-info" to handle rename patches
With v1.5.3.2~14 (apply --index-info: fall back to current index for
mode changes, 2007-09-17), git apply learned to stop worrying
about the lack of diff index line when a file already present in the
current index had no content change.

But it still worries too much: for rename patches, it is checking
that both the old and new filename are present in the current
index.  This makes no sense, since a file rename generally
involves creating a file there was none before.

So just check the old filename.

Noticed while trying to use “git rebase” with diff.renames = copies.

[jn: add tests]

5d27485944 t4150 (am): futureproof against failing tests
Most tests in t4150 begin by navigating to a sane state and
applying some patch:

	git checkout first &&
	git am patch1

If a previous test left behind unmerged files or a .git/rebase-apply
directory, they are untouched and the test fails, causing later tests
to fail, too.  This is not a problem in practice because none of the
tests leave a mess behind.

But as a futureproofing measure, it is still best to avoid the problem
and clean up at the start of each test.  In particular, this
simplifies the process of adding new tests that are known to fail.

800f11040d t4150 (am): style fix
Place setup commands in test_expect_success blocks.  This makes the
rare event of the setup commands breaking on some platform easier to
diagnose, and more importantly, it visually distinguishes where
each test begins and ends.

Instead of running test -z against the result of "git diff" command
substitution, use "git diff --exit-code", to improve output when
running with the "-v" option.

Use test_cmp in place of "test $(foo) = $(bar)" for similar reasons.

Remove whitespace after the > and < redirection operators for
consistency with other tests.

The order of arguments to test_cmp is "test_cmp expected actual".

e3f67d30b2 am: fix patch format detection for Thunderbird "Save As" emails
The patch detection wants to inspect all the headers of a rfc2822 message
and ensure that they look like header fields. The headers are always
separated from the message body with a blank line. When Thunderbird saves
the message the blank line separating the headers from the body includes a
CR. The patch detection is failing because a CRLF doesn't match /^$/. Fix
this by allowing a CR to exist on the separating line.

0fcb2caf29 am: allow individual e-mail files as input
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.

A test is added to t4150 to demonstrate this feature.
