t5323: drop mentions of "master"
Commit 0696232390 (pack-redundant: fix crash when one packfile in repo,
2020-12-16) added one some new tests to t5323. At the time, the sub-repo
we used was called "master". But in a parallel branch, this was switched
to "main".
When the latter branch was merged in 27d7c8599b (Merge branch
'js/default-branch-name-tests-final-stretch', 2021-01-25), some of those
spots caused textual conflicts, but some (for tests that were far enough
away from other changed code) were just semantic. The merge resolution
fixed up most spots, but missed this one.
Even though this did impact actual code, it turned out not to fail the
tests. Running 'cd "$master_repo"' ended up staying in the same
directory, running the test in the main trash repo instead of the
sub-repo. But because the point of the test is checking behavior when
there are no packfiles, it worked in either repo (since both are empty
at this point in the script).

maintenance: skip bootout/bootstrap when plist is registered

schedule. This uses a set of .plist files to describe the schedule, but
these files are also registered with 'launchctl bootstrap'. If multiple

replacing these schedule files and registering them with launchctl.
To avoid extra launchctl commands, do a check for the .plist files on

oidtree: avoid unaligned access to crit-bit tree
The flexible array member "k" of struct cb_node is used to store the key
of the crit-bit tree node. It offers no alignment guarantees -- in fact
the current struct layout puts it one byte after a 4-byte aligned
address, i.e. guaranteed to be misaligned.
oidtree uses a struct object_id as cb_node key. Since cf0983213c (hash:
add an algo member to struct object_id, 2021-04-26) it requires 4-byte
alignment. The mismatch is reported by UndefinedBehaviorSanitizer at
runtime like this:
hash.h:277:2: runtime error: member access within misaligned address 0x00015000802d for type 'struct object_id', which requires 4 byte alignment
0x00015000802d: note: pointer points here

^
SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior hash.h:277:2 in
We can fix that by:
1. eliminating the alignment requirement of struct object_id,
2. providing the alignment in struct cb_node, or
3. avoiding the issue by only using memcpy to access "k".
Currently we only store one of two values in "algo" in struct object_id.
We could use a uint8_t for that instead and widen it only once we add
support for our twohundredth algorithm or so. That would not only avoid
alignment issues, but also reduce the memory requirements for each
instance of struct object_id by ca. 9%.
Supporting keys with alignment requirements might be useful to spread
the use of crit-bit trees. It can be achieved by using a wider type for
"k" (e.g. uintmax_t), using different types for the members "byte" and
"otherbits" (e.g. uint16_t or uint32_t for each), or by avoiding the use
of flexible arrays like khash.h does.
This patch implements the third option, though, because it has the least
potential for causing side-effects and we're close to the next release.
If one of the other options is implemented later as well to get their
additional benefits we can get rid of the extra copies introduced here.

Revert 'diff-merges: let "-m" imply "-p"'
This reverts commit f5bfcc823ba242a46e20fb6f71c9fbf7ebb222fe, which
made "git log -m" imply "--patch" by default. The logic was that
"-m", which makes diff generation for merges perform a diff against
each parent, has no use unless I am viewing the diff, so we could save
the user some typing by turning on display of the resulting diff
automatically. That wasn't expected to adversely affect scripts
because scripts would either be using a command like "git diff-tree"
that already emits diffs by default or would be combining -m with a
diff generation option such as --name-status. By saving typing for
interactive use without adversely affecting scripts in the wild, it
would be a pure improvement.
The problem is that although diff generation options are only relevant
for the displayed diff, a script author can imagine them affecting
path limiting. For example, I might run
git log -w --format=%H -- README
hoping to list commits that edited README, excluding whitespace-only
changes. In fact, a whitespace-only change is not TREESAME so the use
of -w here has no effect (since we don't apply these diff generation
flags to the diff_options struct rev_info::pruning used for this
purpose), but the documentation suggests that it should work
Suppose you specified foo as the <paths>. We shall call
commits that modify foo !TREESAME, and the rest TREESAME. (In
a diff filtered for foo, they look different and equal,
respectively.)
and a script author who has not tested whitespace-only changes
wouldn't notice.
Similarly, a script author could include
git log -m --first-parent --format=%H -- README
to filter the first-parent history for commits that modified README.
The -m is a no-op but it reflects the script author's intent. For
example, until 1e20a407fe2 (stash list: stop passing "-m" to "git
log", 2021-05-21), "git stash list" did this.
As a result, we can't safely change "-m" to imply "-p" without fear of
breaking such scripts. Restore the previous behavior.
Noticed because Rust's src/bootstrap/bootstrap.py made use of this
same construct: https://github.com/rust-lang/rust/pull/87513. That
script has been updated to omit the unnecessary "-m" option, but we
can expect other scripts in the wild to have similar expectations.
