Junio C Hamano 026336cb27 untracked cache: use git_env_bool() not getenv() for customization
GIT_DISABLE_UNTRACKED_CACHE and GIT_TEST_UNTRACKED_CACHE are only
sensed for their presense by using getenv(); use git_env_bool()
instead so that GIT_DISABLE_UNTRACKED_CACHE=false would work as
naïvely expected.

Also rename GIT_TEST_UNTRACKED_CACHE to GIT_FORCE_UNTRACKED_CACHE
to express what it does more honestly.  Forcing its use may be one
useful thing to do while testing the feature, but testing does not
have to be the only use of the knob.

While at it, avoid repeated calls to git_env_bool() by capturing the
return value from the first call in a static variable.

Derrick Stolee ebbed3ba04 revision.c: reduce object database queries
In mark_parents_uninteresting(), we check for the existence of an
object file to see if we should treat a commit as parsed. The result
is to set the "parsed" bit on the commit.

Modify the condition to only check has_object_file() if the result
would change the parsed bit.

When a local branch is different from its upstream ref, "git status"
will compute ahead/behind counts. This uses paint_down_to_common()
and hits mark_parents_uninteresting(). On a copy of the Linux repo
with a local instance of "master" behind the remote branch
"origin/master" by ~60,000 commits, we find the performance of
"git status" went from 1.42 seconds to 1.32 seconds, for a relative
difference of -7.0%.

René Scharfe 53ba2c799a perf: use GIT_PERF_REPEAT_COUNT=3 by default even without config file
9ba95ed23c (perf/run: update get_var_from_env_or_config() for
subsections) stopped setting a default value for GIT_PERF_REPEAT_COUNT
if no perf config file is present, because get_var_from_env_or_config
returns early in that case.

Fix it by setting the default value after calling this function.  Its
fifth parameter is not used for any other variable, so remove the
associated code.

Derrick Stolee 21abed500c sha1_name: fix uninitialized memory errors
During abbreviation checks, we navigate to the position within a
pack-index that an OID would be inserted and check surrounding OIDs
for the maximum matching prefix. This position may be beyond the
last position, because the given OID is lexicographically larger
than every OID in the pack. Then nth_packed_object_oid() does not
initialize "oid".

Use the return value of nth_packed_object_oid() to prevent these
errors.

Also the comment about checking near-by objects miscounts the
neighbours.  If we have a hit at "first", we check "first-1" and
"first+1" to make sure we have sufficiently long abbreviation not to
match either.  If we do not have a hit, "first" is the smallest
among the objects that are larger than what we want to name, so we
check that and "first-1" to make sure we have sufficiently long
abbreviation not to match either.  In either case, we only check up
to two near-by objects.

Junio C Hamano 11395a3b4b test_must_be_empty: make sure the file exists, not just empty
The helper function test_must_be_empty is meant to make sure the
given file is empty, but its implementation is:

	if test -s "$1"
	then
		... not empty, we detected a failure ...
	fi

Surely, the file having non-zero size is a sign that the condition
"the file must be empty" is violated, but it misses the case where
the file does not even exist.  It is an accident waiting to happen
with a buggy test like this:

	git frotz 2>error-message &&
	test_must_be_empty errro-message

that won't get caught until you deliberately break 'git frotz' and
notice why the test does not fail.

Bernhard M. Wiedemann a40e06ee33 perl: call timegm and timelocal with 4-digit year
Amazingly, timegm(gmtime(0)) is only 0 before 2020 because perl's
timegm deviates from GNU timegm(3) in how it handles years.

man Time::Local says

 Whenever possible, use an absolute four digit year instead.

with a detailed explanation about ambiguity of 2-digit years above that.

Even though this ambiguity is error-prone with >50% of users getting it
wrong, it has been like this for 20+ years, so we just use 4-digit years
everywhere to be on the safe side.

We add some extra logic to cvsimport because it allows 2-digit year
input and interpreting an 18 as 1918 can be avoided easily and safely.

Stephen R Guglielmo 8841b5222c subtree: fix add and pull for GPG-signed commits
If log.showsignature is true (or --show-signature is passed) while
performing a `subtree add` or `subtree pull`, the command fails.

toptree_for_commit() calls `log` and passes the output to `commit-tree`.
If this output shows the GPG signature data, `commit-tree` throws a
fatal error.

This commit fixes the issue by adding --no-show-signature to `log` calls
in a few places, as well as using the more appropriate `rev-parse`
instead where possible.

Rasmus Villemoes e2e05d619a grep: move grep_source_init outside critical section
grep_source_init typically does three strdup()s, and in the threaded
case, the call from add_work() happens while holding grep_mutex.

We can thus reduce the time we hold grep_mutex by moving the
grep_source_init() call out of add_work(), and simply have add_work()
copy the initialized structure to the available slot in the todo
array.

This also simplifies the prototype of add_work(), since it no longer
needs to duplicate all the parameters of grep_source_init(). In the
callers of add_work(), we get to reduce the amount of code duplicated in
the threaded and non-threaded cases slightly (avoiding repeating the
long "GREP_SOURCE_OID, pathbuf.buf, path, oid" argument list); a
subsequent cleanup patch will make that even more so.

Jeff King 03aa3783f2 t: send verbose test-helper output to fd 4
Test helper functions like test_must_fail may produce
messages to stderr when they see a problem. When the tests
are run with "--verbose", this ends up on the test script's
stderr, and the user can read it.

But there's a problem. Some tests record stderr as part of
the test, like:

  test_must_fail git foo 2>output &&
  test_i18ngrep expected.message output

In this case the error text goes into "output". This makes
the --verbose output less useful (it also means we might
accidentally match it in the second, though in practice we
tend to produce these messages only on error, so we'd abort
the test when the first command fails).

Let's instead send this user-facing output directly to
descriptor 4, which always points to the original stderr (or
/dev/null in non-verbose mode). And it's already forbidden
to redirect descriptor 4, since we use it for BASH_XTRACEFD,
as explained in 9be795fbce (t5615: avoid re-using descriptor
4, 2017-12-08).

Jeff King f74bbc8dd2 revision: drop --show-all option
This was an undocumented debugging aid that does not seem to
have come in handy in the past decade, judging from its lack
of mentions on the mailing list.

Let's drop it in the name of simplicity. This is morally a
revert of 3131b71301 (Add "--show-all" revision walker flag
for debugging, 2008-02-09), but note that I did leave in the
mapping of UNINTERESTING to "^" in get_revision_mark(). I
don't think this would be possible to trigger with the
current code, but it's the only sensible marker.

We'll skip the usual deprecation period because this was
explicitly a debugging aid that was never documented.

Jeff King 7fa31b645f commit: drop uses of get_cached_commit_buffer()
The "--show-all" revision option shows UNINTERESTING
commits. Some of these commits may be unparsed when we try
to show them (since we may or may not need to walk their
parents to fulfill the request).

Commit 3131b71301 (Add "--show-all" revision walker flag for
debugging, 2008-02-09) resolved this by just skipping
pretty-printing for commits without their object contents
cached, saying:

  Because we now end up listing commits we may not even have been parsed
  at all "show_log" and "show_commit" need to protect against commits
  that don't have a commit buffer entry.

That was the easy fix to avoid the pretty-printer segfaulting,
but:

  1. It doesn't work for all formats. E.g., --oneline
     prints the oid for each such commit but not a trailing
     newline, leading to jumbled output.

  2. It only affects some commits, depending on whether we
     happened to parse them or not (so if they were at the
     tip of an UNINTERESTING starting point, or if we
     happened to traverse over them, you'd see more data).

  3. It unncessarily ties the decision to show the verbose
     header to whether the commit buffer was cached. That
     makes it harder to change the logic around caching
     (e.g., if we could traverse without actually loading
     the full commit objects).

These days it's safe to feed such a commit to the
pretty-print code. Since be5c9fb904 (logmsg_reencode: lazily
load missing commit buffers, 2013-01-26), we'll load it on
demand in such a case. So let's just always show the verbose
headers.

This does change the behavior of plumbing, but:

  a. The --show-all option was explicitly introduced as a
     debugging aid, and was never documented (and has rarely
     even been mentioned on the list by git devs).

  b. Avoiding the commits was already not deterministic due
     to (2) above. So the caller might have seen full
     headers for these commits anyway, and would need to be
     prepared for it.
