In addition to the manual adjustment to let the `linux-gcc` CI job run
the test suite with `master` and then with `main`, this patch makes sure
that GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME is set in all test scripts
that currently rely on the initial branch name being `master by default.
To determine which test scripts to mark up, the first step was to
force-set the default branch name to `master` in
- all test scripts that contain the keyword `master`,
- t4211, which expects `t/t4211/history.export` with a hard-coded ref to
initialize the default branch,
- t5560 because it sources `t/t556x_common` which uses `master`,
- t8002 and t8012 because both source `t/annotate-tests.sh` which also
uses `master`)
This trick was performed by this command:
$ sed -i '/^ *\. \.\/\(test-lib\|lib-\(bash\|cvs\|git-svn\)\|gitweb-lib\)\.sh$/i\
GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\
export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\
' $(git grep -l master t/t[0-9]*.sh) \
t/t4211*.sh t/t5560*.sh t/t8002*.sh t/t8012*.sh
After that, careful, manual inspection revealed that some of the test
scripts containing the needle `master` do not actually rely on a
specific default branch name: either they mention `master` only in a
comment, or they initialize that branch specificially, or they do not
actually refer to the current default branch. Therefore, the
aforementioned modification was undone in those test scripts thusly:

We excluded one set of test scripts in these commands, though: the range

branch in the branch called `p4/master`, which is obviously not the
default branch. Manual analysis revealed that only five of these tests
actually require a specific default branch name to pass; They were
modified thusly:

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

uses `warning()` instead of `advise()`.
One consequence is that the advice is not colorized in the same manner

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.

When 'git repack' creates a pack with the same name as any existing
pack, it moves the existing one to 'old-pack-xxx.{pack,idx,...}' and
then renames the new one into place.
Eventually, it would be nice to have 'git repack' allow for writing a
multi-pack index at the critical time (after the new packs have been
written / moved into place, but before the old ones have been deleted).
Guessing that this option might be called '--write-midx', this makes the
following situation (where repacks are issued back-to-back without any
new objects) impossible:
$ git repack -adb
$ git repack -adb --write-midx
In the second repack, the existing packs are overwritten verbatim with
the same rename-to-old sequence. At that point, the current MIDX is
invalidated, since it refers to now-missing packs. So that code wants to
be run after the MIDX is re-written. But (prior to this patch) the new
MIDX can't be written until the new packs are moved into place. So, we
have a circular dependency.
This is all hypothetical, since no code currently exists to write a MIDX
safely during a 'git repack' (the 'GIT_TEST_MULTI_PACK_INDEX' does so
unsafely). Putting hypothetical aside, though: why do we need to rename
existing packs to be prefixed with 'old-' anyway?
This behavior dates all the way back to 2ad47d6 (git-repack: Be
careful when updating the same pack as an existing one., 2006-06-25).
2ad47d6 is mainly concerned about a case where a newly written pack
would have a different structure than its index. This used to be
possible when the pack name was a hash of the set of objects. Under this
naming scheme, two packs that store the same set of objects could differ
in delta selection, object positioning, or both. If this happened, then
any such packs would be unreadable in the instant between copying the
new pack and new index (i.e., either the index or pack will be stale
depending on the order that they were copied).
But since 1190a1a (pack-objects: name pack files after trailer hash,
2013-12-05), this is no longer possible, since pack files are named not
after their logical contents (i.e., the set of objects), but by the
actual checksum of their contents. So, this old- behavior can safely go,
which allows us to avoid our circular dependency above.
In addition to avoiding the circular dependency, this patch also makes
'git repack' a lot simpler, since we don't have to deal with failures
encountered when renaming existing packs to be prefixed with 'old-'.
This patch is mostly limited to removing code paths that deal with the
'old' prefixing, with the exception of files that include the pack's
name in their own filename, like .idx, .bitmap, and related files. The
exception is that we want to continue to trust what pack-objects wrote.
That is, it is not the case that we pretend as if pack-objects didn't
write files identical to ones that already exist, but rather that we
respect what pack-objects wrote as the source of truth. That cuts two
ways:
- If pack-objects produced an identical pack to one that already
exists with a bitmap, but did not produce a bitmap, we remove the
bitmap that already exists. (This behavior is codified in t7700.14).
- If pack-objects produced an identical pack to one that already
exists, we trust the just-written version of the coresponding .idx,
.promisor, and other files over the ones that already exist. This
ensures that we use the most up-to-date versions of this files,
which is safe even in the face of format changes in, say, the .idx
file (which would not be reflected in the .idx file's name).

It is possible for the name of an alias to end with the name of another
alias, in which case the code will incorrectly detect a loop.
We can fix that by adding an extra space between words.

Ever since 'git pull' learned '--recurse-submodules' in a6d7eb2c7a
(pull: optionally rebase submodules (remote submodule changes only),
2017-06-23), we check if there are local submodule modifications by
checking the revision range 'curr_head --not rebase_fork_point'.
The goal of this check is to abort the pull if there are submodule
modifications in the local commits being rebased, since this scenario is
not supported.
However, the actual range of commits being rebased is not
'rebase_fork_point..curr_head', as the logic in
'get_rebase_newbase_and_upstream' reveals, it is 'upstream..curr_head'.
If the 'git merge-base --fork-point' invocation in
'get_rebase_fork_point' fails to find a fork point between the current
branch and the remote-tracking branch we are pulling from,
'rebase_fork_point' is null and since 4d36f88be7 (submodule: do not pass
null OID to setup_revisions, 2018-05-24), 'submodule_touches_in_range'
checks 'curr_head' and all its ancestors for submodule modifications.
Since it is highly likely that there are submodule modifications in this
range (which is in effect the whole history of the current branch), this
prevents 'git pull --rebase --recurse-submodules' from succeeding if no
fork point exists between the current branch and the remote-tracking
branch being pulled. This can happen, for example, when the current
branch was forked from a commit which was never recorded in the reflog
of the remote-tracking branch we are pulling, as the last two paragraphs
of the "Discussion on fork-point mode" section in git-merge-base(1)
explain.
Fix this bug by passing 'upstream' instead of 'rebase_fork_point' as the
'excl_oid' argument to 'submodule_touches_in_range'.

It can be hard at first glance to distinguish what is different between
the two tests 'recursive rebasing pull' and 'pull rebase recursing fails
with conflicts' in 't5572-pull-submodule.sh', and to understand how they
relate to the scenarios described in a6d7eb2c7a (pull: optionally rebase
submodules (remote submodule changes only), 2017-06-23), which
implemented '--recurse-submodules' for 'git pull' and added these tests.
Rename the tests to be more descriptive and add some bullet points
comments describing the different scenarios.
