The hashmap API is just complicated enough that even at least one
long-time Git contributor has to look up how to use it every time he
finds a new use case. When that happens, it is really useful if the
provided example code is correct...
While at it, "fix a memory leak", avoid statements before variable
declarations, fix a const -> no-const cast, several %l specifiers (which
want to be %ld), avoid using an undefined constant, call scanf()
correctly, use FLEX_ALLOC_STR() where appropriate, and adjust the style
here and there.

There have been a few complaints on the mailing list that git-clone doesn't
respect the `submodule.recurse` setting, which every other command (that
potentially knows how to deal with submodules) respects. In case of clone
this is not beneficial to respect as the user may not want to obtain all
submodules (assuming a pathspec of '.').
Improve the documentation such that the pathspec is mentioned in the
synopsis to alleviate the confusion around the submodule recursion flag
in git-clone.
While at it clarify that the option can be given multiple times for complex
pathspecs.

Commit 74ed43711f (grep: enable recurse-submodules to work on <tree>
objects, 2016-12-16) taught 'tree_entry_interesting()' to be able to
match across submodule boundaries in the presence of wildcards. This is
done by performing literal matching up to the first wildcard and then
punting to the submodule itself to perform more accurate pattern
matching. Instead of introducing a new flag to request this behavior,
commit 74ed43711f overloaded the already existing 'recursive' flag in
'struct pathspec' to request this behavior.
This leads to a bug where whenever any other caller has the 'recursive'
flag set as well as a pathspec with wildcards that all submodules will
be indicated as matches. One simple example of this is:
git init repo
cd repo
git init submodule
git -C submodule commit -m initial --allow-empty
touch "[bracket]"
git add "[bracket]"
git commit -m bracket
git add submodule
git commit -m submodule
git rev-list HEAD -- "[bracket]"
Fix this by introducing the new flag 'recurse_submodules' in 'struct
pathspec' and using this flag to determine if matches should be allowed
to cross submodule boundaries.
This fixes https://github.com/git-for-windows/git/issues/1371.

Since 180a9f2268 (provide a facility for "delayed" progress
reporting, 2007-04-20), the progress code has allowed
callers to skip showing progress if they have reached a
percentage-threshold of the total work before the delay
period passes.
But since 8aade107dd (progress: simplify "delayed" progress
API, 2017-08-19), that parameter is not available to outside
callers (we always passed zero after that commit, though
that was corrected in the previous commit to "100%").
Let's drop the threshold code, which never triggers in
any meaningful way.

Commit 8aade107dd (progress: simplify "delayed" progress
API, 2017-08-19) dropped the parameter by which callers
could say "show my progress only if I haven't passed M%
progress after N seconds". The intent was to just show
nothing for 2 seconds, and then always progress after that.
But we flipped the logic in the wrapper: it sets M=0,
meaning that we'd almost _never_ show progress after 2
seconds, since we'd generally have made some progress. This
should have been 100%, not 0%.
We were fooled by existing calls like:
start_progress_delay("foo", 0, 0, 2);
which behaved this way. The trick is that the first "0"
there is "how many items total", and there zero means "we
don't know". And without knowing that, we cannot compute a
completed percent at all, and we ignored the threshold
parameter entirely! Modeling our wrapper after that broke
callers which pass a non-zero value for "total".
We can switch to the intended behavior by using "100" in the
wrapper call.

Replace use of strbuf_addf() with strbuf_add() when enumerating
loose objects in for_each_file_in_obj_subdir(). Since we already
check the length and hex-values of the string before consuming
the path, we can prevent extra computation by using the lower-
level method.
One consumer of for_each_file_in_obj_subdir() is the abbreviation
code. OID abbreviations use a cached list of loose objects (per
object subdirectory) to make repeated queries fast, but there is
significant cache load time when there are many loose objects.
Most repositories do not have many loose objects before repacking,
but in the GVFS case the repos can grow to have millions of loose
objects. Profiling 'git log' performance in GitForWindows on a
GVFS-enabled repo with ~2.5 million loose objects revealed 12% of
the CPU time was spent in strbuf_addf().
Add a new performance test to p4211-line-log.sh that is more
sensitive to this cache-loading. By limiting to 1000 commits, we
more closely resemble user wait time when reading history into a
pager.
For a copy of the Linux repo with two ~512 MB packfiles and ~572K
loose objects, running 'git log --oneline --parents --raw -1000'
had the following performance:

In the documentation of diff-tree, it is stated that the -l option
"prevents rename/copy detection from running if the number of
rename/copy targets exceeds the specified number". The documentation
does not mention any special handling for the number 0, but the
implementation before commit 9f7e4bfa3b ("diff: remove silent clamp of
renameLimit", 2017-11-13) treated 0 as a special value indicating that
the rename limit is to be a very large number instead.
The commit 9f7e4bfa3b changed that behavior, treating 0 as 0. Revert
this behavior to what it was previously. This allows existing scripts
and tools that use "-l0" to continue working. The alternative (to have
"-l0" suppress rename detection) is probably much less useful, since
users can just refrain from specifying -M and/or -C to have the same
effect.

If you come to the documentation thinking "I do not want Git
to take any locks for my background processes", then you may
easily run across "--no-optional-locks" in git.txt.
But it's quite reasonable to hit a specific instance of the
problem: you have "git status" running in the background,
and you notice that it causes lock contention with other
processes. So you look in git-status.txt to see if there is
a way to disable it, but there's no mention of the flag.
Let's add a short note mentioning that status does indeed
touch the index (and why), with a pointer to the global
option. That can point users in the right direction and help
