The DO_MATCH_LEADING_PATHSPEC had a fall-through case for if there was a

if a further paths under the current directory might match due to the

then we shouldn't get to that fall-through case.

Commit be8a84c526 ("dir.c: make 'git-status --ignored' work within
leading directories", 2013-04-15) noted that
git status --ignored <SOMEPATH>
would not list ignored files and directories within <SOMEPATH> if
<SOMEPATH> was untracked, and modified the behavior to make it show
them. However, it did so via a hack that broke consistency; it would
show paths under <SOMEPATH> differently than a simple
git status --ignored | grep <SOMEPATH>
would show them. A correct fix is slightly more involved, and
complicated slightly by this hack, so we revert this commit (but keep
corrected versions of the testcases) and will later fix the original
bug with a subsequent patch.
Some history may be helpful:
A very, very similar case to the commit we are reverting was raised in
commit 48ffef966c ("ls-files: fix overeager pathspec optimization",
2010-01-08); but it actually went in somewhat the opposite direction. In
that commit, it mentioned how
git ls-files -o --exclude-standard t/
used to show untracked files under t/ even when t/ was ignored, and then
changed the behavior to stop showing untracked files under an ignored
directory. More importantly, this commit considered keeping this
behavior but noted that it would be inconsistent with the behavior when
multiple pathspecs were specified and thus rejected it.
The reason for this whole inconsistency when one pathspec is specified
versus zero or two is because common prefixes of pathspecs are sent
through a different set of checks (in treat_leading_path()) than normal
file/directory traversal (those go through read_directory_recursive()
and treat_path()). As such, for consistency, one needs to check that
both codepaths produce the same result.
Revert commit be8a84c526, except instead
of removing the testcase it added, modify it to check for correct and
consistent behavior. A subsequent patch in this series will fix the
testcase.

Add several tests demonstrating directory traversal failures of various
sorts in dir.c (and one similar looking test that turns out to be a
git_fnmatch bug). A lot of these tests look like near duplicates of
each other, but an optimization path in dir.c to pre-descend into a
common prefix and the specialized treatment of trailing slashes in dir.c
mean the tiny differences are sometimes important and potentially cause
different codepaths to be explored.
Of the 7 failing tests, 2 are new to git-2.24.0 (tweaked by side effects
of the en/clean-nested-with-ignored-topic); the other 5 also failed
under git-2.23.0 and earlier.

In 13cdf78094 (format-patch: teach format.notes config option,
2019-05-16), the order in which git_config() and repo_init_revisions()
were swapped so that `rev.notes_opt` would be initialized before
git_config() was called. This is problematic, however, as git_config()
should generally be called before repo_init_revisions().
Break this circular dependency by creating `show_notes` and `notes_opt`
which git_config() reads into. Then, copy these values over to
`rev.show_notes` and `rev.notes_opt` after repo_init_revisions() is
called.

When we had multiple `format.notes` config values where we had `<ref1>`,
`false`, `<ref2>` (in that order), then we would print out the notes for
both `<ref1>` and `<ref2>`. This doesn't make sense, however, since we
parse the config in a top-down manner and a `false` should be able to
override previous configurations, just like how `--no-notes` will
override previous `--notes`.
Duplicate the logic that handles the `--[no-]notes[=]` option to
`format.notes` for consistency. As a result, when parsing the config
from top to bottom, `format.notes = true` will behave like `--notes`,
`format.notes = <ref>` will behave like `--notes=<ref>` and
`format.notes = false` will behave like `--no-notes`.
This change isn't strictly backwards compatible but since it is an edge
case where a sane user would not mix notes refs with `false` and this
feature is relatively new (released only in v2.23.0), this change should
be harmless.

Earlier patches in this series moved a couple of conditions from the
recursive name_rev() function into its caller name_ref(), for no other
reason than to make eliminating the recursion a bit easier to follow.
Since the previous patch name_rev() is not recursive anymore, so let's
move all those conditions back into name_rev().

The name_rev() function calls itself recursively for each interesting
parent of the commit it got as parameter, and, consequently, it can
segfault when processing a deep history if it exhausts the available
stack space. E.g. running 'git name-rev --all' and 'git name-rev
HEAD~100000' in the gcc, gecko-dev, llvm, and WebKit repositories
results in segfaults on my machine ('ulimit -s' reports 8192kB of
stack size limit), and nowadays the former segfaults in the Linux repo
as well (it reached the necessasry depth sometime between v5.3-rc4 and
-rc5).
Eliminate the recursion by inserting the interesting parents into a
LIFO 'prio_queue' [1] and iterating until the queue becomes empty.
Note that the parent commits must be added in reverse order to the
LIFO 'prio_queue', so their relative order is preserved during
processing, i.e. the first parent should come out first from the
queue, because otherwise performance greatly suffers on mergy
histories [2].
The stacksize-limited test 'name-rev works in a deep repo' in
't6120-describe.sh' demonstrated this issue and expected failure. Now
the recursion is gone, so flip it to expect success. Also gone are
the dmesg entries logging the segfault of that segfaulting 'git
name-rev' process on every execution of the test suite.
Note that this slightly changes the order of lines in the output of
'git name-rev --all', usually swapping two lines every 35 lines in
git.git or every 150 lines in linux.git. This shouldn't matter in
practice, because the output has always been unordered anyway.
This patch is best viewed with '--ignore-all-space'.
[1] Early versions of this patch used a 'commit_list', resulting in
~15% performance penalty for 'git name-rev --all' in 'linux.git',
presumably because of the memory allocation and release for each
insertion and removal. Using a LIFO 'prio_queue' has basically no
effect on performance.
[2] We prefer shorter names, i.e. 'v0.1~234' is preferred over
'v0.1^2~5', meaning that usually following the first parent of a
merge results in the best name for its ancestors. So when later
we follow the remaining parent(s) of a merge, and reach an already
named commit, then we usually find that we can't give that commit
a better name, and thus we don't have to visit any of its
ancestors again.
OTOH, if we were to follow the Nth parent of the merge first, then
the name of all its ancestors would include a corresponding '^N'.
Those are not the best names for those commits, so when later we
reach an already named commit following the first parent of that
merge, then we would have to update the name of that commit and
the names of all of its ancestors as well. Consequently, we would
have to visit many commits several times, resulting in a
significant slowdown.

Following the previous patches in this series we can get the value of
'name_rev()'s 'tip_name' parameter from the 'struct rev_name'
associated with the commit as well.
So let's use 'name->tip_name' instead, which makes the patch
eliminating the recursion of name_rev() a bit easier to follow.
Note that at this point we could drop the 'tip_name' parameter as
well, but that parameter will be necessary later, after the recursion
is eliminated.

flush_current_id() prints the hexadecimal representation of two object

Since dcb3450fd8 (sha1_to_hex() usage cleanup, 2006-05-03) it rotates
through four buffers, which allows to print up to four object IDs at the
