When "git p4" imports changelist that removes paths, it failed to
convert pathnames when the p4 used encoding different from the one
used on the Git side. This has been corrected.

The current code wants to record an error condition from
either ferror() or fclose(), but makes sure that we always
call both functions. So it can't use logical-OR "||", which
would short-circuit when ferror() is true. Instead, it uses
bitwise-OR "|" to evaluate both functions and set one or
more bits in the "err" flag if they reported a failure.
Unlike logical-OR, though, bitwise-OR does not introduce a
sequence point, and the order of evaluation for its operands
is unspecified. So a compiler would be free to generate code
which calls fclose() first, and then ferror() on the
now-freed filehandle.
There's no indication that this has happened in practice,
but let's write it out in a way that follows the standard.

It is often useful to break a commit into multiple parts that are more
logical separations. This can be tricky to learn how to do without the
brute-force method if re-writing code or commit messages from scratch.
Add a section to the git-reset documentation which shows an example
process for how to use git add -p and git commit -c HEAD@{1} to
interactively break a commit apart and re-use the original commit
message as a starting point when making the new commit message.

We resolve HEAD and copy the result to a fixed-size buffer
with memcpy, never checking that it actually fits. This bug
dates back to 8098a178b (Add git-symbolic-ref, 2005-09-30).
Before that we used readlink(), which took a maximum buffer
size.
We can fix this by using resolve_refdup(), which duplicates
the buffer on the heap. That also lets us just check
for a NULL pointer to see if we have resolved HEAD, and
drop the extra head_p variable.

When removing the hack for isatty(), we actually removed more than just
an isatty() hack: we removed the hack where internal data structures of
the MSVC runtime are modified in order to redirect stdout/stderr.
Instead of using that hack (that does not work with newer versions of
the runtime, anyway), we replaced it by reopening the respective file
descriptors.
What we forgot was to mark stderr as unbuffered again.

A server can end up in a state where there are lots of unreferenced
loose objects (say, because many users are doing a bunch of rebasing
and pushing their rebased branches). Running "git gc --auto" in
this state would cause a gc.log file to be created, preventing
future auto gcs, causing pack files to pile up. Since many git
operations are O(n) in the number of pack files, this would lead to
poor performance.
Git should never get itself into a state where it refuses to do any
maintenance, just because at some point some piece of the maintenance
didn't make progress.
Teach Git to ignore gc.log files which are older than (by default)
one day old, which can be tweaked via the gc.logExpiry configuration
variable. That way, these pack files will get cleaned up, if
necessary, at least once per day. And operators who find a need for
more-frequent gcs can adjust gc.logExpiry to meet their needs.
There is also some cleanup: a successful manual gc, or a
warning-free auto gc with an old log file, will remove any old
gc.log files.
It might still happen that manual intervention is required
(e.g. because the repo is corrupt), but at the very least it won't
be because Git is too dumb to try again.

The documentation gives an example of the submodule foreach
command that uses both backticks and single-quotes. We stick
the whole thing inside "+" markers to make it monospace, but
the inside punctuation still needs escaping. We handle the
backticks with "{backtick}", and use backslash-escaping for
the single-quotes.
But we missed the escaping on the second quote. Fortunately,
asciidoc renders this unbalanced quote as we want (showing
the quote), but asciidoctor does not. We could fix it by
adding the missing backslash.
However, let's take a step back. Even when rendered
correctly, it's hard to read a long command stuck into the
middle of a paragraph, and the important punctuation is hard
to notice. Let's instead bump it into its own single-line
code block. That makes both the source and the rendered
result more readable, and as a bonus we don't have to worry
about quoting at all.

prune_cache() first identifies those entries at the start of the sorted
array that can be discarded. Then it moves the rest of the entries up.
Last it identifies the unwanted trailing entries among the moved ones
and cuts them off.

first and then move only those entries to the top. The resulting code

In a9e38359e3 we taught git-p4 a way to re-encode path names from what
was used in Perforce to UTF-8. This path re-encoding worked properly for
"added" paths. "Removed" paths were not re-encoded and therefore
different from the "added" paths. Consequently, these files were not
removed in a git-p4 cloned Git repository because the path names did not
match.
Fix this by moving the re-encoding to a place that affects "added" and
"removed" paths. Add a test to demonstrate the issue.

Use OpenSSL's SHA-1 routines rather than builtin block-sha1 routines.
This improves performance on SHA1 operations on Intel processors.
OpenSSL 1.0.2 has made considerable performance improvements and
support the Intel hardware acceleration features. See:
https://software.intel.com/en-us/articles/improving-openssl-performancehttps://software.intel.com/en-us/articles/intel-sha-extensions
To test this I added/staged a single file in a gigantic
repository having a 450MB index file. The code in read-cache.c
verifies the header SHA as it reads the index and computes a new
header SHA as it writes out the new index. Therefore, in this test
the SHA code must process 900MB of data. Testing was done on an
Intel I7-4770 CPU @ 3.40GHz (Intel64, Family 6, Model 60) CPU.
The block-sha1 version averaged 5.27 seconds.
The OpenSSL version averaged 4.50 seconds.

When using non-builtin protocols relying on a transport helper
(such as http), push options are not propagated to the helper.
The user could ask for push options and a push would seemingly succeed,
but the push options would never be transported to the server,
misleading the users expectation.
Fix this by propagating the push options to the transport helper.
This is only addressing the first issue of
(1) the helper protocol does not propagate push-option
(2) the http helper is not prepared to handle push-option
Once we fix (2), the http transport helper can make use of push options
as well, but that happens as a follow up. (1) is a bug fix, whereas (2)
is a feature, which is why we only do (1) here.
