If you have a pcre1 library which is compiled with JIT enabled then
PCRE_STUDY_JIT_COMPILE will be defined whether or not the
NO_LIBPCRE1_JIT configuration is set.
This means that we enable JIT functionality when calling pcre_study
even if NO_LIBPCRE1_JIT has been explicitly set and we just use plain
pcre_exec later.
Fix this by using own macro (GIT_PCRE_STUDY_JIT_COMPILE) which we set to
PCRE_STUDY_JIT_COMPILE only if NO_LIBPCRE1_JIT is not set and define to
0 otherwise, as before.

t4201: make use of abbreviation in the test more robust
The test for '--abbrev' in t4201-shortlog.sh assumes that the commits
generated in the test can always be uniquely abbreviated to 5 hex digits
but this is not always the case. If you were unlucky and happened to run
the test at (say) Thu Jun 22 03:04:49 2017 +0000, you would find that
the first commit generated would collide with a tree object created
later in the same test.
This can be simulated in the version of t4201-shortlog.sh prior to this
commit by setting GIT_COMMITTER_DATE and GIT_AUTHOR_DATE to 1498100689
after sourcing test-lib.sh.
Change the test to test --abbrev=35 instead of --abbrev=5 to almost
completely avoid the possibility of a partial collision and add a call
to test_tick in the setup to make the test repeatable (the latter alone
is sufficient to make it robust enough).

apply: avoid out-of-bounds access in fuzzy_matchlines()
fuzzy_matchlines() uses a pointers to the first and last characters of
two lines to keep track while matching them. This makes it impossible
to deal with empty strings. It accesses characters before the start of
empty lines. It can also access characters after the end when checking
for trailing whitespace in the main loop.
Avoid that by using pointers to the first character and the one *after*
the last one. This is well-defined as long as the latter is not
dereferenced. Basically rewrite the function based on that premise; it
becomes much simpler as a result. There is no need to check for
leading whitespace outside of the main loop anymore.

fsmonitor: store fsmonitor bitmap before splitting index
ba1b9cac ("fsmonitor: delay updating state until after split index
is merged", 2017-10-27) resolved the problem of the fsmonitor data
being applied to the non-base index when reading; however, a similar
problem exists when writing the index. Specifically, writing of the
fsmonitor extension happens only after the work to split the index
has been applied -- as such, the information in the index is only
for the non-"base" index, and thus the extension information
contains only partial data.
When saving, compute the ewah bitmap before the index is split, and
store it in the fsmonitor_dirty field, mirroring the behavior that
occurred during reading. fsmonitor_dirty is kept from being leaked by
being freed when the extension data is written -- which always happens
precisely once, no matter the split index configuration.

merge-base --fork-point doc: clarify the example and failure modes
The illustrated history used to explain the `--fork-point` mode
named three keypoint commits B3, B2 and B1 from the oldest to the
newest, which was hard to read. Relabel them to B0, B1, B2. Also
illustrate the history after the rebase using the `--fork-point`
facility was made.
The text already mentions use of reflog, but the description is not
clear what benefit we are trying to gain by using reflog. Clarify
that it is to find the commits that were known to be at the tip of
the remote-tracking branch. This in turn necessitates users to know
the ramifications of the underlying assumptions, namely, expiry of
reflog entries will make it impossible to determine which commits
were at the tip of the remote-tracking branches and we fail when in
doubt (instead of giving a random and incorrect result without even
warning). Another limitation is that it won't be useful if you did
not fork from the tip of a remote-tracking branch but from in the
middle.
We currently have seven callers of `reduce_heads(foo)`. Six of them do
not use the original list `foo` again, and actually, all six of those
end up leaking it.
Introduce and use `reduce_heads_replace(&foo)` as a leak-free version of
`foo = reduce_heads(foo)` to fix several of these. Fix the remaining
leaks using `free_commit_list()`.

In several functions, we iterate through a commit list by assigning
`result = result->next`. As a consequence, we lose the original pointer
and eventually leak the list.
Rewrite the loops so that we keep the original pointers, then call
`free_commit_list()`. Various alternatives were considered:
1) Use `UNLEAK(result)` before the loop. Simple change, but not very
pretty. These would definitely be new lows among our usages of UNLEAK.
2) Use `pop_commit()` when looping. Slightly less simple change, but it
feels slightly preferable to first display the list, then free it.
3) As in this patch, but with `UNLEAK()` instead of freeing. We'd still
go through all the trouble of refactoring the loop, and because it's not
super-obvious that we're about to exit, let's just free the lists -- it
probably doesn't affect the runtime much.
In `handle_independent()` we can drop `result` while we're here and
reuse the `revs`-variable instead. That matches several other users of
`reduce_heads()`. The memory-leak that this hides will be addressed in

I haven't found a way to address that "(Main)" namespace when getting
the namespace ids: indeed, when listing namespaces, there is no
"canonical" field for the main namespace, although there is a "*"
field that is set to "" (empty). So in theory, we could specify the
empty namespace to get the main namespace, but that would make
specifying namespaces harder for the user: we would need to teach
users about the "empty" default namespace. It would also make the code
more complicated: we'd need to parse quotes in the configuration.

"(Main)" since that is the publicly documented name.

wt-status: actually ignore submodules when requested
Since ff6f1f564 (submodule-config: lazy-load a repository's .gitmodules
file, 2017-08-03) rebase interactive fails if there are any submodules
with unstaged changes which have been configured with a value for
'submodule.<name>.ignore' in the repository's config.
This is due to how configured values of 'submodule.<name>.ignore' are
handled in addition to a change in how the submodule config is loaded.
When the diff machinery hits a submodule (gitlink as well as a
corresponding entry in the submodule subsystem) it will read the value
of 'submodule.<name>.ignore' stored in the repository's config and if
the config is present it will clear the 'IGNORE_SUBMODULES' (which is
the flag explicitly requested by rebase interactive),
'IGNORE_UNTRACKED_IN_SUBMODULES', and 'IGNORE_DIRTY_SUBMODULES' diff
flags and then set one of them based on the configured value.
Historically this wasn't a problem because the submodule subsystem
wasn't initialized because the .gitmodules file wasn't explicitly loaded
by the rebase interactive command. So when the diff machinery hit a
submodule it would skip over reading any configured values of
'submodule.<name>.ignore'.
In order to preserve the behavior of submodules being ignored by rebase
interactive, also set the 'OVERRIDE_SUBMODULE_CONFIG' diff flag when
submodules are requested to be ignored when checking for unstaged
changes.

To make them more generic and make it easy to reuse them,
the following changes are made:
- we don't require capabilities to come in a fixed order,
- we allow duplicates,
- we check that the remote supports the capabilities we
advertise,
- we don't check if the remote declares any capability we
don't know about.
The reason behind the last change is that the protocol
should work using only the capabilities that both ends
support, and it should not stop working if one end starts
to advertise a new capability.
Despite those changes, we can still require a set of

This only matters if there are TREESAME-commits. Since they should be
skipped, they are not included in `cnt` and we will hit the situation
where we set `p->next` to NULL. As a result, the list will be one longer
than it should be. The last commit in the list will be one which occurs
earlier, or which shouldn't be included.
Do not update `p` the very last round in the loop. This ensures that
after the loop, `p->next` points to the remainder of the list, and we
can set it to NULL. While we're here, free that remainder to fix a
memory leak.

`find_bisection()` rebuilds the commit list it is given by reversing it
and skipping uninteresting commits. The uninteresting list entries are
leaked. Free them to fix the leak.

bisect: change calling-convention of `find_bisection()`
This function takes a commit list and returns a commit list. The
returned list is built by modifying the original list. Thus the caller
should not use the original list again (and after the next commit fixes
a memory leak, it must not).
Change the function signature so that it takes a **list and has void
return type. That should make it harder to misuse this function.
While we're here, document this function.

Credentials exposed by the secret service DBUS interface may be locked.
Setting the SECRET_SEARCH_UNLOCK flag will make the secret service
unlock these secrets, possibly prompting the user for credentials to do
so. Without this flag, the secret is simply not loaded.

Andrew Baumann reported that when called outside of any Git worktree,
`git rev-parse --is-inside-work-tree` eventually tries to access
`//HEAD`, i.e. any `HEAD` file in the root directory, but with a double
slash.
This double slash is not only unintentional, but is allowed by the POSIX
standard to have a special meaning. And most notably on Windows, it
does, where it refers to a UNC path of the form `//server/share/`.
As a consequence, afore-mentioned `rev-parse` call not only looks for
the wrong thing, but it also causes serious delays, as Windows will try
to access a server called `HEAD`. Let's simply avoid the unintended
double slash.

Response codes are optional. Exit parse_response_code() early if it's
passed a NULL string, indicating that we reached the end of the reply.
This avoids dereferencing said NULL pointer.
