[PATCH v3 00/12] Improve git-am test coverage

[PATCH v3 00/12] Improve git-am test coverage

[Paul Tan]

This is a very minor re-roll of [v2] that adds in the missing !MINGW prereq in
t3901.  Thanks Johannes Schindelin and Johannes Sixt for the reviews last
round. Interdiff below.

Previous versions:

[v1] http://thread.gmane.org/gmane.comp.version-control.git/273254
[v2] http://thread.gmane.org/gmane.comp.version-control.git/273507

Increase test coverage of git-am.sh to help prevent regressions that could
arise from the rewrite of git-am.sh to C. This patch series, along with
pt/am-foreign, improved test coverage as measured by kcov from 56.5%[1] to
67.3%[2].

No tests for git-am's interactive mode, though, as test_terminal does not seem
to attach a pseudo-tty to stdin(?), thus making git-am's "test -t 0" check
fail.

This is part of my GSoC project to rewrite git-am.sh to a C builtin[3].

[PATCH v3 01/12] t4150: am.messageid really adds the message id

[Paul Tan]

Since a078f73 (git-am: add --message-id/--no-message-id, 2014-11-25),
the am.messageid setting determines whether the --message-id option is
set by default.

Add a test for this.

[PATCH v3 02/12] t4150: am fails if index is dirty

[Paul Tan]

Since d1c5f2a (Add git-am, applymbox replacement., 2005-10-07), git-am
will ensure that the index is clean before applying the patch. This is
to prevent changes unrelated to the patch from being committed.

Add a test for this check.

[PATCH v3 03/12] t4151: am --abort will keep dirty index intact

[Paul Tan]

Since 7b3b7e3 (am --abort: keep unrelated commits since the last failure
and warn, 2010-12-21), git-am --abort will not touch the index if on the
previous invocation, git-am failed because the index is dirty. This is
to ensure that the user's modifications to the index are not discarded.

Add a test for this.

[Paul Tan]

Since c95b138 (Fix git-am safety checks, 2006-09-15), when there is a
session in progress, git-am will check the command-line arguments and
standard input to ensure that the user does not pass it any patches.

[PATCH v3 10/12] t4150: tests for am --[no-]scissors

[Paul Tan]

Since 017678b (am/mailinfo: Disable scissors processing by default,
2009-08-26), git-am supported the --[no-]scissors option, passing it to
git-mailinfo.

Add tests to ensure that git-am will pass the --scissors option to
git-mailinfo, and that --no-scissors will override the configuration
setting of mailinfo.scissors.

[PATCH v3 11/12] t3418: non-interactive rebase --continue with rerere enabled

[Paul Tan]

Since 8389b52 (git-rerere: reuse recorded resolve., 2006-01-28), git-am
will call git-rerere to re-use recorded merge conflict resolutions if
any occur in a threeway merge.

Add a test to ensure that git-rerere is called by git-am (which handles
the non-interactive rebase).

[PATCH v3 12/12] t3901: test git-am encoding conversion

[Paul Tan]

Since d1c5f2a (Add git-am, applymbox replacement., 2005-10-07), git-am
supported the --utf8 and --no-utf8 options, and if set, would pass the
-u flag and the -k flag respectively.

git mailinfo -u will re-code the commit log message and authorship info
in the charset specified by i18n.commitencoding setting, while
git mailinfo -n will disable the re-coding.

Since d84029b (--utf8 is now default for 'git-am', 2007-01-08), --utf8
is set by default in git-am.

Add various encoding conversion tests to t3901 to test git-mailinfo's
encoding conversion. In addition, add a test for --no-utf8 to check that
no encoding conversion will occur if that option is set.
