The recursive merge strategy has some special handling when the tree for
the merge branch exactly matches the merge base, but that code path is
missing checks for the index having changes relative to HEAD. Add a
testcase covering this scenario.

t/helper/test-lazy-init-name-hash.c:115:6: note: ‘nr_threads_used’ was declared here

I do not see how we can arrive at that line without having `nr_threads_used`
initialized, as we'd have `count > 1` (which asserts that we ran the
loop above at least once, such that it *should* be initialized).
Just clear the variable at the beginning of the function to squelch
the warning.

The previous steps added test_when_finished to tests that run 'git
pull' or 'git merge' with expectation of success, so that the test
after them can start from a known state even when their 'git pull'
invocation unexpectedly fails. However, tests that run 'git pull'
or 'git merge' expecting it not to succeed forgot to protect later
tests the same way---if they unexpectedly succeed, the test after
them would start from an unexpected state.
Reset and checkout the initial commit after all these tests, whether
they expect their invocations to succeed or fail.

The code internal to the recursive merge strategy was not fully
prepared to see a path that is renamed to try overwriting another
path that is only different in case on case insensitive systems.
This does not matter in the current code, but will start to matter
once the rename detection logic starts taking hints from nearby
paths moving to some directory and moves a new path along with them.
* en/merge-recursive-icase-removal:

Historically, the diff machinery for rename detection had a

Sometimes users are given a hash of an object and they want to
identify it further (ex.: Use verify-pack to find the largest blobs,
but what are these? or [1])
When describing commits, we try to anchor them to tags or refs, as these
are conceptually on a higher level than the commit. And if there is no ref
or tag that matches exactly, we're out of luck. So we employ a heuristic
to make up a name for the commit. These names are ambiguous, there might
be different tags or refs to anchor to, and there might be different
path in the DAG to travel to arrive at the commit precisely.
When describing a blob, we want to describe the blob from a higher layer
as well, which is a tuple of (commit, deep/path) as the tree objects
involved are rather uninteresting. The same blob can be referenced by
multiple commits, so how we decide which commit to use? This patch
implements a rather naive approach on this: As there are no back pointers
from blobs to commits in which the blob occurs, we'll start walking from
any tips available, listing the blobs in-order of the commit and once we
found the blob, we'll take the first commit that listed the blob. For
example
git describe --tags v0.99:Makefile
conversion-901-g7672db20c2:Makefile
tells us the Makefile as it was in v0.99 was introduced in commit 7672db20.
The walking is performed in reverse order to show the introduction of a
blob rather than its last occurrence.

When the N-th previous thing checked out syntax (@{-N}) is used
with '--branch' option of check-ref-format the result may not be
the name of a branch that currently exists or ever existed. This
is because @{-N} is used to refer to the N-th last checked out
"thing", which might be a commit object name if the previous check
out was a detached HEAD state; or a branch name, otherwise. The
documentation thus does a wrong thing by promoting it as the
"previous branch syntax".
State that @{-N} is the syntax for specifying "N-th last thing
checked out" and also state that the result of using @{-N} might
also result in an commit object name.

folder = "[Gmail]/Drafts"
host = imaps://imap.gmail.com
port = 993
sslverify = false
results in the following error,
curl_easy_perform() failed: URL using bad/illegal format or missing URL
This is a consequence of not URI-encoding the folder portion of
the URL which contains characters such as '[' which are not
allowed in a URI. According to RFC3986, these characters should be
URI-encoded.
So, URI-encode the folder before adding it to the URI to ensure it doesn't
contain characters that aren't allowed in a URI.

In particular when local tags are used (or tags that are pushed to some
fork) to build Git, it is very hard to figure out from which particular
revision a particular Git executable was built. It gets worse when those
tags are deleted, or even updated.
Let's just report an exact, unabbreviated commit name in our build
options.
We need to be careful, though, to report when the current commit cannot
be determined, e.g. when building from a tarball without any associated
Git repository. This could be the case also when extracting Git's source
code into an unrelated Git worktree.

Move the definition of the transport-specific functions provided by
transports, whether declared in transport.c or transport-helper.c, into
an internal header. This means that transport-using code (as opposed to
transport-declaring code) can no longer access these functions (without
importing the internal header themselves), making it clear that they
should use the transport_*() functions instead, and also allowing the
interface between the transport mechanism and an individual transport to
independently evolve.
This is superficially a reversal of commit 824d5776c3 ("Refactor
struct transport_ops inlined into struct transport", 2007-09-19).
However, the scope of the involved variables was neither affected nor
discussed in that commit, and I think that the advantages in making
those functions more private outweigh the advantages described in that
commit's commit message. A minor additional point is that the code has
gotten more complicated since then, in that the function-pointer
variables are potentially mutated twice (once initially and once if
transport_take_over() is invoked), increasing the value of corralling
them into their own struct.

Setting SVNSERVE_PORT enables several tests which require a local
svnserve daemon to be run (in t9113 & t9126). The tests share setup of
the local svnserve via `start_svnserve()`. The function uses svnserve's
`--listen-once` option, which causes svnserve to accept one connection
on the port, serve it, and exit. When running the tests in parallel
this fails if one test tries to start svnserve while the other is still
running.
Use the test number as the svnserve port (similar to httpd tests) to
avoid port conflicts. Developers can set GIT_TEST_SVNSERVE to any value
other than 'false' or 'auto' to enable these tests.
