The algorithm in can_all_from_reach_with_flags() performs a depth-
first-search, terminated by generation number, intending to use
a hueristic that "important" commits are found in the first-parent
history. This heuristic is valuable in scenarios like fetch
negotiation.
However, there is a problem! After the search finds a target commit,
it should pop all commits off the stack and mark them as "can reach".
This logic is incorrect, so the algorithm instead walks all reachable
commits above the generation-number cutoff.
The existing algorithm is still an improvement over the previous
algorithm, as the worst-case complexity went from quadratic to linear.
The performance measurement at the time was good, but not dramatic.
By fixing this heuristic, we reduce the number of walked commits.
We can also re-run the performance tests from commit 4fbcca4e
"commit-reach: make can_all_from_reach... linear".
Performance was measured on the Linux repository using
'test-tool reach can_all_from_reach'. The input included rows seeded by
tag values. The "small" case included X-rows as v4.[0-9]* and Y-rows as
v3.[0-9]*. This mimics a (very large) fetch that says "I have all major
v3 releases and want all major v4 releases." The "large" case included
X-rows as "v4.*" and Y-rows as "v3.*". This adds all release-candidate
tags to the set, which does not greatly increase the number of objects
that are considered, but does increase the number of 'from' commits,
demonstrating the quadratic nature of the previous code.
Small Case:
4fbcca4e~1: 0.85 s
4fbcca4e: 0.26 s (num_walked: 1,011,035)
HEAD: 0.14 s (num_walked: 8,601)
Large Case:
4fbcca4e~1: 24.0 s
4fbcca4e: 0.12 s (num_walked: 503,925)
HEAD: 0.06 s (num_walked: 217,243)

We explicitly omitted -Wunused-function when we added
-Wextra, but there is no need: the current code compiles
cleanly with it. And it's worth having, since it can let you
know when there are cascading effects from a cleanup (e.g.,
deleting one function lets you delete its static helpers).
There are cases where we may need an unused function to
exist, but we can handle these easily:
- macro-generated code like commit-slab; there we have the
MAYBE_UNUSED annotation to silence the compiler
- conditional compilation, where we may or may not need a
static helper. These generally fall into one of two
categories:
- the call should not be conditional, but rather the
function body itself should be (and may just be a
no-op on one side of the #if). That keeps the
conditional pollution out of the main code.
- call-chains of static helpers should all be in the
same #if block, so they are all-or-nothing
And if there's some case that doesn't cover, we still
have MAYBE_UNUSED as a fallback.

The commit-graph and multi-pack-index features introduce optional
data structures that are not required for normal Git operations.
It is important to run the normal test suite without them enabled,
but it is helpful to also run the test suite using them.
Our continuous integration scripts include a second test stage that
runs with optional GIT_TEST_* variables enabled. Add the following
two variables to that stage:
GIT_TEST_COMMIT_GRAPH
GIT_TEST_MULTI_PACK_INDEX
This will slow down the operation, as we build a commit-graph file
after every 'git commit' operation and build a multi-pack-index
during every 'git repack' operation. However, it is important that
future changes are compatible with these features.

The tree:0 filter does not need to traverse the trees that it has
filtered out, so optimize list-objects and list-objects-filter to skip
traversing the trees entirely. Before this patch, we iterated over all
children of the tree, and did nothing for all of them, which was
wasteful.

and you're stuck reading the source code to find it. Let's

This reverts commit 744f7c4c31.
These targets do depend on the fact that each prereq is explicitly
listed via their use of $^, which I failed to notice, and broke the
build.
branch_get sometimes returns current_branch, which can be NULL (e.g., if
you're on a detached HEAD). Try:
$ git branch HEAD
fatal: no such branch 'HEAD'
$ git branch ''
fatal: no such branch ''
However, it seems weird that we'd check those cases here (and provide
such lousy messages). And indeed, dropping that and letting us
eventually hit create_branch() gives a much better message:
$ git branch HEAD
fatal: 'HEAD' is not a valid branch name.
$ git branch ''
fatal: '' is not a valid branch name.

When rerolling a patch series, including various Reviewed-by etc. that

So pick up any *-by lines, with a new suppression category 'misc-by',

suppression category. It seems natural to make 'misc-by' implied by
'body'.
