a119eaa89a t4210: skip command-line encoding tests on mingw
On Windows the application command line is provided as unicode and in
mingw-git we convert that to utf-8. So these tests that require a iso-8859-1
input are being subverted by the encoding transformations we perform and

84ec869136 Work around a problem identified by BuildHive
Apparently the signal handling is not quite correct in the fsckobject
handling (most likely we rely on a side effect that lets us still output
some message after receiving a signal 13 but in the BuildHive setup this
fails intermittently).

As a consequence, the push in t5504 does fail as expected, but fails to
output anything (unexpected). Since this is good enough for now, let's
handle an empty output as success, too.

11c5a274a2 MinGW: disable legacy encoding tests
On Windows, all native APIs are Unicode-based. It is impossible to pass
legacy encoded byte arrays to a process via command line or environment
variables. Disable the tests that try to do so.

In t3901, most tests still work if we don't mess up the repository encoding
in setup, so don't switch to ISO-8859-1 on MinGW.

Note that i18n tests that do their encoding tricks via encoded files (such
as t3900) are not affected by this.

101c85a6b4 work around misdetection of stdin attached to a tty
Git on Windows was made aware of the fact that sometimes a file may be
used by another process and so an operation may fail but the user might
be able to fix it and is asking for confirmation whether it should
retry.

This is implemented in a way that git only asks in case stdin and stderr
are attached to a tty. Unfortunately this seems to be misdetected
sometimes causing the testsuite to hang when git is waiting for a user
answer.

This patch works around the situation.

a0332337be t7700: do not use "touch" unnecessarily
Some versions of touch (such as /usr/ucb/touch on Solaris)
do not know about the "-r" option. This would make sense as
a feature of test-chmtime, but fortunately this fix is even
easier.

The test does not care about the timestamp of the .keep file it
creates at all, only that it exists. For such a use case, with or
without portability issues around "-r", "touch" should not be used
in the first place.

088304bf73 t7501: fix "empty commit" test with NO_PERL
t7501.9 tries to check that "git commit" will fail when the
index is unchanged. It relies on previous tests not to have
modified the index. When it was originally written, this was
always the case. However, commit c65dc35 (t7501: test the
right kind of breakage, 2012-03-30) changed earlier tests (4
and 5) to leave a modification in the index.

We never noticed, however, because t7501.7, between the two,
clears the index state as a side effect. However, that test
depends on the PERL prerequisite, and so it does not always
run. Therefore if NO_PERL is set, we do not run the
intervening test, the index is left unclean, and t7501.9
fails.

We could fix this by moving t7501.9 up in the script.
However, this patch instead leaves it in place and adds a
"git reset" before the commit. This makes the test more
explicit about its preconditions, and will future-proof it
against any other changes in the test state.

Commit 9d7d446 (git p4: submit files with wildcards, 2012-04-29)
fixed problems with handling files that had p4 wildcard
characters, like "@" and "*".  But it missed one case, that of
RCS keyword scrubbing, which uses "p4 fstat" to extract type
information.  Fix it by calling wildcard_encode() on the raw
filename.

0cf1b72a38 git p4 test: do not pollute /tmp
Generating the submit template for p4 uses tempfile.mkstemp(),
which by default puts files in /tmp.  For a test that fails,
possibly on purpose, this is not cleaned up.  Run with TMPDIR
pointing into the trash directory so the temp files go away
with the test results.

To do this required some other minor changes.  First, the editor
is launched using system(editor + " " + template_file), using
shell expansion to build the command string.  This doesn't work
if editor has a space in it.  And is generally unwise as it's
easy to fool the shell into doing extra work.  Exec the args
directly, without shell expansion.

Second, without shell expansion, the trick of "P4EDITOR=:" used
in the tests doesn't work.  Use a real command, true, as the
non-interactive editor for testing.

40f846c35c git p4: work around p4 bug that causes empty symlinks
Damien Gérard highlights an interesting problem.  Some p4
repositories end up with symlinks that have an empty target.  It
is not possible to create this with current p4, but they do
indeed exist.

The effect in git p4 is that "p4 print" on the symlink returns an
empty string, confusing the curret symlink-handling code.

Such broken repositories cause problems in p4 as well, even with
no git involved.  In p4, syncing to a change that includes a
bogus symlink causes errors:

    //depot/empty-symlink - updating /home/me/p4/empty-symlink
    rename: /home/me/p4/empty-symlink: No such file or directory

and leaves no symlink.

In git, replicate the p4 behavior by ignoring these bad symlinks.
If, in a later p4 revision, the symlink happens to point to
something non-null, the symlink will be replaced properly.

Add a big test for all this too.

This happens to be a regression introduced by 1292df1 (git-p4:
Fix occasional truncation of symlink contents., 2013-08-08) and
appeared first in 1.8.5.  But it shows up only in p4 repositories
of dubious character, so can wait for a proper release.

ea97002fc9 t/perf: time rev-list with UNINTERESTING commits
We time a straight "rev-list --all" and its "--object"
counterpart, both going all the way to the root. However, we
do not time a partial history walk. This patch adds an
extreme case: a walk over a very small slice of history, but
with a very large set of UNINTERESTING tips. This is similar
to the connectivity check run by git on a small fetch, or
the walk done by any pre-receive hooks that want to check
incoming commits.

a74352867e revision: propagate flag bits from tags to pointees
With the previous fix 895c5ba3 (revision: do not peel tags used in
range notation, 2013-09-19), handle_revision_arg() that processes
command line arguments for the "git log" family of commands no
longer directly places the object pointed by the tag in the pending
object array when it sees a tag object.  We used to place pointee
there after copying the flag bits like UNINTERESTING and
SYMMETRIC_LEFT.

This change meant that any flag that is relevant to later history
traversal must now be propagated to the pointed objects (most often
these are commits) while starting the traversal, which is partly
done by handle_commit() that is called from prepare_revision_walk().
We did propagate UNINTERESTING, but did not do so for others, most
notably SYMMETRIC_LEFT.  This caused "git log --left-right v1.0..."
(where "v1.0" is a tag) to start losing the "leftness" from the
commit the tag points at.

2ac5e4470b revision: mark contents of an uninteresting tree uninteresting
"git rev-list --objects ^A^{tree} B^{tree}" ought to mean "I want a
list of objects inside B's tree, but please exclude the objects that
appear inside A's tree".

we see the top-level tree marked as uninteresting (i.e. ^A^{tree} in
the above example) and call mark_tree_uninteresting() on it; this
unfortunately prevents us from recursing into the tree and marking
the objects in the tree as uninteresting.

The reason why "git log ^A A" yields an empty set of commits,
i.e. we do not have a similar issue for commits, is because we call
mark_parents_uninteresting() after seeing an uninteresting commit.
The uninteresting-ness of the commit itself does not prevent its
parents from being marked as uninteresting.

Introduce mark_tree_contents_uninteresting() and structure the code
in handle_commit() in such a way that it makes it the responsibility
of the callchain leading to this function to mark commits, trees and
blobs as uninteresting, and also make it the responsibility of the
helpers called from this function to mark objects that are reachable
from them.

Note that this is a very old bug that probably dates back to the day
when "rev-list --objects" was introduced.  The line to clear
tree->object.parsed at the end of mark_tree_contents_uninteresting()
can be removed when this fix is merged to the codebase after
6e454b9a (clear parsed flag when we free tree buffers, 2013-06-05).
