The Travis CI configuration we ship ran the tests with --verbose
option but this risks non-TAP output that happens to be "ok" to be
misinterpreted as TAP signalling a test that passed. This resulted
in unnecessary failure. This has been corrected by introducing a
new mode to run our tests in the test harness to send the verbose
output separately to the log file.

In a worktree connected to a repository elsewhere, created via "git
worktree", "git checkout" attempts to protect users from confusion
by refusing to check out a branch that is already checked out in
another worktree. However, this also prevented checking out a
branch, which is designated as the primary branch of a bare
reopsitory, in a worktree that is connected to the bare
repository. The check has been corrected to allow it.

When there is a TAP harness consuming the output of our test
scripts, the "--verbose" breaks the output by mingling
test command output with TAP. Because the TAP::Harness
module used by "prove" is fairly lenient, this _usually_
works, but it violates the spec, and things get very
confusing if the commands happen to output a line that looks
like TAP (e.g., the word "ok" on its own line).
Let's detect this situation and complain. Just calling
error() isn't great, though; prove will tell us that the
script failed, but the message doesn't make it through to
the user. Instead, we can use the special TAP signal "Bail
out!". This not only shows the message to the user, but
instructs the harness to stop running the tests entirely.
This is exactly what we want here, as the problem is in the
command-line options, and every test script would produce
the same error.
The result looks like this (the first "Bailout called" line
is in red if prove uses color on your terminal):
$ make GIT_TEST_OPTS='--verbose --tee'
rm -f -r 'test-results'
*** prove ***
Bailout called. Further testing stopped: verbose mode forbidden under TAP harness; try --verbose-log
FAILED--Further testing stopped: verbose mode forbidden under TAP harness; try --verbose-log

The "--verbose" option redirects output from arbitrary
test commands to stdout. This is useful for examining the
output manually, like:
./t5547-push-quarantine.sh -v | less
But it also means that the output is intermingled with the
TAP directives, which can confuse a TAP parser like "prove".
This has always been a potential problem, but became an
issue recently when one test happened to output the word
"ok" on a line by itself, which prove interprets as a test
success:
$ prove t5547-push-quarantine.sh :: -v
t5547-push-quarantine.sh .. 1/? To dest.git
* [new branch] HEAD -> master
To dest.git
! [remote rejected] reject -> reject (pre-receive hook declined)

Result: FAIL
One answer is "if it hurts, don't do it", but that's not
quite the whole story. The Travis tests use "--verbose
--tee" so that they can get the benefit of prove's parallel
options, along with a verbose log in case there is a
failure. We just need the verbose output to go to the log,
but keep stdout clean.
Getting this right turns out to be surprisingly difficult.
Here's the progression of alternatives I considered:
1. Add an option to write verbose output to stderr. This is
hard to capture, though, because we want each test to
have its own log (because they're all run in parallel
and the jumbled output would be useless).
2. Add an option to write verbose output to a file in
test-results. This works, but the log is missing all of
the non-verbose output, which gives context.
3. Like (2), but teach say_color() to additionally output
to the log. This mostly works, but misses any output
that happens outside of the say() functions (which isn't
a lot, but is a potential maintenance headache).
4. Like (2), but make the log file the same as the "--tee"
file. That almost works, but now we have two processes
opening the same file. That gives us two separate
descriptors, each with their own idea of the current
position. They'll each start writing at offset 0, and
overwrite each other's data.
5. Like (4), but in each case open the file for appending.
That atomically positions each write at the end of the
file.
It's possible we may still get sheared writes between
the two processes, but this is already the case when
writing to stdout. It's not a problem in practice
because the test harness generally waits for snippets to
finish before writing the TAP output.
We can ignore buffering issues with tee, because POSIX
mandates that it does not buffer. Likewise, POSIX
specifies "tee -a", so it should be available
everywhere.
This patch implements option (5), which seems to work well
in practice.

We are careful in test_done to handle a results directory
with a space in it, but the "--tee" code path does not.

An "add --chmod=+x" test recently added by 610d55af0f ("add: modify
already added files when --chmod is given", 2016-09-14) used "xfoo3"
as a test file. The paths xfoo[1-3] were used by earlier tests for
symbolic links but they were expected to have been removed by the
time the execution reached this new test.
The removal with "git reset --hard" however happened in a pair of
earlier tests, both of which are protected by POSIXPERM,SANITY
prerequisites. Platforms and test environments that lacked these
would have seen xfoo3 as a leftover symbolic link that points at
somewhere else at this point of the sequence, and the chmod test
would have given a wrong result.

When we auto-follow tags in a fetch, we look at all of the
tags advertised by the remote and fetch ones where we don't
already have the tag, but we do have the object it peels to.
This involves a lot of calls to has_sha1_file(), some of
which we can reasonably expect to fail. Since 45e8a74
(has_sha1_file: re-check pack directory before giving up,
2013-08-30), this may cause many calls to
reprepare_packed_git(), which is potentially expensive.
This has gone unnoticed for several years because it
requires a fairly unique setup to matter:
1. You need to have a lot of packs on the client side to
make reprepare_packed_git() expensive (the most
expensive part is finding duplicates in an unsorted
list, which is currently quadratic).
2. You need a large number of tag refs on the server side
that are candidates for auto-following (i.e., that the
client doesn't have). Each one triggers a re-read of
the pack directory.
3. Under normal circumstances, the client would
auto-follow those tags and after one large fetch, (2)
would no longer be true. But if those tags point to
history which is disconnected from what the client
otherwise fetches, then it will never auto-follow, and
those candidates will impact it on every fetch.
So when all three are true, each fetch pays an extra
O(nr_tags * nr_packs^2) cost, mostly in string comparisons
on the pack names. This was exacerbated by 47bf4b0
(prepare_packed_git_one: refactor duplicate-pack check,
2014-06-30) which uses a slightly more expensive string
check, under the assumption that the duplicate check doesn't
happen very often (and it shouldn't; the real problem here
is how often we are calling reprepare_packed_git()).
This patch teaches fetch to use HAS_SHA1_QUICK to sacrifice
accuracy for speed, in cases where we might be racy with a
simultaneous repack. This is similar to the fix in 0eeb077
(index-pack: avoid excessive re-reading of pack directory,
2015-06-09). As with that case, it's OK for has_sha1_file()
occasionally say "no I don't have it" when we do, because
the worst case is not a corruption, but simply that we may
fail to auto-follow a tag that points to it.
Here are results from the included perf script, which sets
up a situation similar to the one described above:
Test HEAD^ HEAD

The --fork-point option looks in the reflog to try to find
where a derived branch forked from a base branch. However,
if the reflog for the base branch is totally empty (as it
commonly is right after cloning, which does not write a
reflog entry), then our for_each_reflog call will not find
any entries, and we will come up with no merge base, even
though there may be one with the current tip of the base.
We can fix this by just adding the current tip to
our list of collected entries.

Our ref resolution first runs lstat() on any path we try to
look up, because we want to treat symlinks specially (by
resolving them manually and considering them symrefs). But
if the results of `readlink` do _not_ look like a ref, we
fall through to treating it like a normal file, and just
read the contents of the linked path.
Since fcb7c76 (resolve_ref_unsafe(): close race condition
reading loose refs, 2013-06-19), that "normal file" code
path will stat() the file and if we see ENOENT, will jump
back to the lstat(), thinking we've seen inconsistent
results between the two calls. But for a symbolic ref, this
isn't a race: the lstat() found the symlink, and the stat()
is looking at the path it points to. We end up in an
infinite loop calling lstat() and stat().
We can fix this by avoiding the retry-on-inconsistent jump
when we know that we found a symlink. While we're at it,
let's add a comment explaining why the symlink case gets to
this code in the first place; without that, it is not
obvious that the correct solution isn't to avoid the stat()
code path entirely.

We need to use this function whenever the buffer we want to pass to
regexec(3) may have been mmap(2)ed (and is hence not NUL-terminated).
Note: the original motivation for this patch was to fix a bug where
`git diff -G <regex>` would crash. This patch converts more callers,
though, some of which allocated to construct NUL-terminated strings,
or worse, modified buffers to temporarily insert NULs while calling

When our pickaxe code feeds file contents to regexec(), it implicitly
assumes that the file contents are read into implicitly NUL-terminated
buffers (i.e. that we overallocate by 1, appending a single '\0').
This is not so.
In particular when the file contents are simply mmap()ed, we can be
virtually certain that the buffer is preceding uninitialized bytes, or
invalid pages.
Note that the test we add here is known to be flakey: we simply cannot
know whether the byte following the mmap()ed ones is a NUL or not.
Typically, on Linux the test passes. On Windows, it fails virtually
every time due to an access violation (that's a segmentation fault for
you Unix-y people out there). And Windows would be correct: the
regexec() call wants to operate on a regular, NUL-terminated string,
there is no NUL in the mmap()ed memory range, and it is undefined
whether the next byte is even legal to access.
When run with --valgrind it demonstrates quite clearly the breakage, of
course.
Being marked with `test_expect_failure`, this test will sometimes be
declare "TODO fixed", even if it only passes by mistake.
This test case represents a Minimal, Complete and Verifiable Example of
a breakage reported by Chris Sidi.

differences by exiting with a non-zero status code just like "diff"
does; the exit status codes 126 and above however are special in
that they are used to signal that the command is not executable,
does not exist, or killed by a signal. "git difftool" has been
taught to notice these exit status codes.

"git checkout --detach <branch>" used to give the same advice
message as that is issued when "git checkout <tag>" (or anything
that is not a branch name) is given, but asking with "--detach" is
an explicit enough sign that the user knows what is going on. The
advice message has been squelched in this case.

checkout: do not mention detach advice for explicit --detach option

When "git merge-recursive" works on history with many criss-cross
merges in "verbose" mode, the names the command assigns to the
virtual merge bases could have overwritten each other by unintended
reuse of the same piece of memory.
* rs/pull-signed-tag:
commit: use FLEX_ARRAY in struct merge_remote_desc
merge-recursive: fix verbose output for multiple base trees
commit: factor out set_merge_remote_desc()
commit: use xstrdup() in get_merge_parent()
