A test allowed both "git push" and "git receive-pack" on the other
end write their traces into the same file. This is OK on platforms
that allows atomically appending to a file opened with O_APPEND,

When peeling a tag for prepare_revision_walk(), we do not
respect the ignore_missing_links flag. This can lead to a
bogus error when pack-objects walks the possibly-broken
unreachable-but-recent part of the object graph.
The other link-following all happens via traverse_commit_list(),
which explains why this case was missed. And our tests
covered only broken links from commits. Let's be more
comprehensive and cover broken tree entries (which do work)
and tags (which shows off this bug).

"git interpret-trailers" is unaware of the cut line, and assumes the
trailer block would be at the end of the whole thing. This can easily
be seen with:
$ GIT_EDITOR='git interpret-trailers --in-place --trailer Acked-by:me' \
git commit --amend -v
Teach "git interpret-trailers" to notice the cut-line and ignore the
remainder of the input when looking for a place to add new trailer
block. This makes it consistent with how "git commit -v -s" inserts a
new Signed-off-by: line.
This can be done by the same logic as the existing helper function,
wt_status_truncate_message_at_cut_line(), uses, but it wants the caller
to pass a strbuf to it. Because the function ignore_non_trailer() used
by the command takes a <pointer, length> pair, not a strbuf, steal the
logic from wt_status_truncate_message_at_cut_line() to create a new
wt_status_locate_end() helper function that takes <pointer, length>
pair, and make ignore_non_trailer() call it to help "interpret-trailers".
Since there is only one caller of wt_status_truncate_message_at_cut_line()
in cmd_commit(), rewrite it to call wt_status_locate_end() helper instead
and remove the old helper that no longer has any caller.

One test in t5400 examines the packet exchange between git-push and
git-receive-pack. The latter inherits the GIT_TRACE_PACKET environment
variable, so that both processes dump trace data into the same file
concurrently. This should not be a problem because the trace file is
opened with O_APPEND.
On Windows, however, O_APPEND is not atomic as it should be: it is
emulated as lseek(SEEK_END) followed by write(). For this reason, the
test is unreliable: it can happen that one process overwrites a line
that was just written by the other process. As a consequence, the test
sometimes does not find one or another line that is expected (and it is
also successful occasionally).
The test case is actually only interested in the output of git-push.
To ensure that only git-push writes to the trace file, override the
receive-pack command such that it does not even open the trace file.

The recent change that introduced autodecorating of refs accidentally
broke the ability of users to set log.decorate = false to override it.
When the git_log_config was traversed a second time with an option other
than log.decorate, the decoration style would be set to the automatic
style, even if the user had already overridden it. Instead of setting
the option in config parsing, set it in init_log_defaults instead.
Add a test for this case. The actual additional config option doesn't
matter, but it needs to be something not already set in the
configuration file.

The "--local" option instructs git-config to read or modify
the repository-level config. This doesn't make any sense if
you're not actually in a repository.
Older versions of Git would blindly try to read or write
".git/config". For reading, this would result in a quiet
failure, since there was no config to read (and thus no
matching config value). Writing would generally fail
noisily, since ".git" was unlikely to exist. But since
b1ef400ee (setup_git_env: avoid blind fall-back to ".git",
2016-10-20), we catch this in the call to git_pathdup() and
die with an assertion.
Dying is the right thing to do, but we should catch the
problem early and give a more human-friendly error message.
Note that even without --local, git-config will sometimes
default to using local repository config (e.g., when
writing). These cases are already protected by similar
checks, and covered by a test in t1308.

The purpose of t0027 is to test all CRLF related conversions at "git
checkout" and "git add". Running t0027 under Git for Windows takes
3-4 minutes, so the whole script had been marked as "EXPENSIVE".
However, the "Git for Windows" fork overrides this since 2014:
"t0027 is marked expensive, but really, for MinGW we want to run
these tests always."
The test seems not to be expensive on other platforms at all: it
takes less than 14 seconds under Linux, and 63 seconds under Mac Os
X, and this is more or less the same with a SSD or a spinning disk.
So let's drop the "EXPENSIVE" prereq.
While at it, retire t0025; recent "stress" tests show that t0025 is
flaky, reported by Lars Schneider <larsxschneider@gmail.com>, but
all tests in t0025 are covered by t0027 already.

Currently 'git add' is the only command which dies when launched from an
unpopulated submodule (the place-holder directory for a submodule which
hasn't been checked out). This is triggered implicitly by passing the
PATHSPEC_STRIP_SUBMODULE_SLASH_EXPENSIVE flag to 'parse_pathspec()'.
Instead make this desire more explicit by creating a function
'die_in_unpopulated_submodule()' which dies if the provided 'prefix' has
a leading path component which matches a submodule in the the index.

The test t4051-diff-function-context.sh passes on Linux when
core.autocrlf=true even without marking its support files as LF-only,
but they fail when core.autocrlf=true in Git for Windows' SDK.
The reason is that `grep ... >file.c.new` will keep CR/LF line endings
on Linux (obviously treating CRs as if they were regular characters),
but will be converted to LF-only line endings with MSYS2's grep that is
used in Git for Windows.
As we do not want to validate the way the available `grep` works, let's
just mark the input as LF-only and move on.

The test suite is mainly developed on Linux and MacOSX, which is the
reason that nobody thought to mark files as LF-only as needed.
The symptom is a test suite that fails left and right when being checked
out using Git for Windows (which defaults to core.autocrlf=true).
Mostly, the problems stem from Git's (LF-only) output being compared to
hard-coded files that are checked out with line endings according to
core.autocrlf (which is of course incorrect). This includes the two test
files in t/diff-lib/, README and COPYING.
This patch can be validated even on Linux by using this cadence:
git config core.autocrlf true
rm .git/index && git stash
make -j15 DEVELOPER=1 test

The current convention is to either generate files on the fly in tests,
or to use supporting files taken from a t/tNNNN/ directory (where NNNN
matches the test's number, or the number of the test from which we
borrow supporting files).
The test t3901-i18n-patch.sh was obviously introduced before that
convention was in full swing, hence its supporting files still lived in
t/t3901-8859-1.txt and t/t3901-utf8.txt, respectively.
Let's adjust to the current convention.
