When holding the lock for rewriting the credential file, use a timeout
to avoid race conditions when the credentials file needs to be updated
in parallel.
An example would be doing `fetch --all` on a repository with several
remotes that need credentials, using parallel fetching.
The timeout can be configured using "credentialStore.lockTimeoutMS",
defaulting to 1 second.

A review exchange may begin with a reviewer asking "what did you
mean by this phrase in your log message (or here in the doc)?", the
author answering what was meant, and then the reviewer saying "ah,
that is what you meant---then the flow of the logic makes sense".
But that is not the happy end of the story. New contributors often
forget that the material that has been reviewed in the above exchange
is still unclear in the same way to the next person who reads it,
until it gets updated.
While we are in the vicinity, rephrase the verb "request" used to
refer to comments by reviewers to "suggest"---this matches the
contrast between "original" and "suggested" that appears later in
the same paragraph, and more importantly makes it clearer that it is
not like authors are to please reviewers' wishes but rather
reviewers are merely helping authors to polish their commits.

make a conscious decision about whether they want their pull to merge or

This warning was clearly intended to advise users, but as pointed out in

uses `warning()` instead of `advise()`.

We do not need to hard-code the actual branch name, as we can use the

The `onbranch` test cases touched by this patch do not actually try to
include any other config. Their purpose is to avoid regressing on two
bugs in the `include.onbranch:<name>.path` code that we fixed in the
past, bugs that are actually unrelated to any concrete branch name.
The first bug was fixed in 85fe0e800c (config: work around bug with
includeif:onbranch and early config, 2019-07-31). Essentially, when
reading early config, there would be a catch-22 trying to access the
refs, and therefore we simply cannot evaluate the condition at that
point. The test case ensures that we avoid emitting this bogus message:
BUG: refs.c:1851: attempting to get main_ref_store outside of repository
The second test case concerns the non-Git scenario, where we simply do
not have a current branch to begin with (because we don't have a
repository in the first place), and the test case was introduced in
22932d9169 (config: stop checking whether the_repository is NULL,
2019-08-06) to ensure that we don't cause a segmentation fault should
the code still incorrectly try to look at any ref.
In short, neither of these two test cases will ever look at a current
branch name, even in case of regressions. Therefore, the actual branch
name does not matter at all. We can therefore easily avoid
racially-charged branch names here, and that's what this patch does.

Some test prereqs depend on other prereqs, so in a couple of cases we
have nested prereqs that look something like this:
test_lazy_prereq FOO '
test_have_prereq BAR &&
check-foo
'
This can be problematic, because lazy prereqs are evaluated in the
'$TRASH_DIRECTORY/prereq-test-dir' directory, which is the same for
every prereq, and which is automatically removed after the prereq has
been evaluated. So if the inner prereq (BAR above) is a lazy prereq
that hasn't been evaluated yet, then after its evaluation the
'prereq-test-dir' shared with the outer prereq will be removed.
Consequently, 'check-foo' will find itself in a non-existing
directory, and won't be able to create/access any files in its cwd,
which could result in an unfulfilled outer prereq.
Luckily, this doesn't affect any of our current nested prereqs, either
because the inner prereq is not a lazy prereq (e.g. MINGW, CYGWIN or
PERL), or because the outer prereq happens to be checked without
touching any paths in its cwd (GPGSM and RFC1991 in 'lib-gpg.sh').
So to prevent nested prereqs from interfering with each other let's
evaluate each prereq in its own dedicated directory by appending the
prereq's name to the directory name, e.g. 'prereq-test-dir-SYMLINKS'.
In the test we check not only that the prereq test dir is still there,
but also that the inner prereq can't mess with the outer prereq's
files.

In load_idx(), we check that the .idx file is sized appropriately for
the number of objects it claims to have. We recently fixed the case
where the number of objects caused our expected size to overflow a
32-bit unsigned int, and we switched to size_t.
On a 64-bit system, this is fine; our size_t covers any expected size.
On a 32-bit system, though, it won't. The file may claim to have 2^31
objects, which will overflow even a size_t.
This doesn't hurt us at all for a well-formed idx file. A 32-bit system
would already have failed to mmap such a file, since it would be too
big. But an .idx file which _claims_ to have 2^31 objects but is
actually much smaller would fool our check.
This is a broken file, and for the most part we don't care that much
what happens. But:
- it's a little friendlier to notice up front "woah, this file is
broken" than it is to get nonsense results
- later access of the data assumes that the loading function
sanity-checked that we have at least enough bytes for the regular
object-id table. A malformed .idx file could lead to an
out-of-bounds read.
So let's use our overflow-checking functions to make sure that we're not
fooled by a malformed file.
