When running gpg-relevant tests, a gpg-daemon is spawned for each
GNUPGHOME used. This daemon may stay running after the test and cache
file descriptors for the trash directories, even after the trash
directory is removed. This leads to ENOENT errors when attempting to
create files if tests are run multiple times.
Add a cleanup script to force flushing the gpg-agent for that GNUPGHOME
(if any) before setting up the GPG relevant-environment.

We set the current and local branch colors at the top of the
build_format() function. Let's do the same for the remote
color. This saves a little bit of repetition, but more
importantly it puts all of the color-setting in the same
place. That makes it easier to see that we are coloring all
possibilities.

Since 949af0684 (branch: use ref-filter printing APIs,
2017-01-10), git-branch's output is generated by passing a
custom format to the ref-filter code. This format forgot to
pass BRANCH_COLOR_LOCAL, meaning that local branches
(besides the current one) were never colored at all.
We can add it in the %(if) block where we decide whether the
branch is "current" or merely "local". Note that this means
the current/local coloring is either/or. You can't set:
[color "branch"]
local = blue
current = bold
and expect the current branch to be "bold blue". This
matches the pre-949af0684 behavior.

When assembling the ref-filter format to show "git branch"
output, we put the "%(if)%(HEAD)" conditional at the start
of the overall format. But there's no point in checking
whether a remote branch matches HEAD, as it never will.
The check should go inside the local conditional; we
assemble that format inside the "local" strbuf.
By itself, this is just a minor optimization. But in a
future patch, we'll need this refactoring to fix
local-branch coloring.

When we encounter an error adding reflogs for a walk, we try
to free any logs we have read. But we didn't free all
fields, meaning that we could in theory leak all of the
"items" array (which would consitute the bulk of the
allocated memory).
This patch adds a helper which frees all of the entries and
uses it as appropriate.
As it turns out, the leak seems impossible to trigger with
the current code. Of the three error paths that free the
complete_reflogs struct, two only kick in when the items
array is empty, and the third was removed entirely in the
previous commit.
So this patch should be a noop in terms of behavior, but it
fixes a potential maintenance headache should anybody add a
new error path and copy the partial-free code. Which is
what happened in 5026b47175 (add_reflog_for_walk: avoid
memory leak, 2017-05-04), though its leaky call was the
third one that was recently removed.

The add_reflog_for_walk() function keeps a cache mapping
refnames to their reflog contents. We use a cached reflog
entry if available, and otherwise allocate and store a new
one.
Since 5026b47175 (add_reflog_for_walk: avoid memory leak,
2017-05-04), when we hit an error parsing a date-based
reflog spec, we free the reflog memory but leave the cache
entry pointing to the now-freed memory.
We can fix this by just leaving the memory intact once it
has made it into the cache. This may leave an unused entry
in the cache, but that's OK. And it means we also catch a
similar situation: we may not have allocated at all in this
invocation, but simply be pointing to a cached entry from a
previous invocation (which is relying on that entry being
present).
The new test in t1411 exercises this case and fails when run
with --valgrind or ASan.

As part of the add_reflog_to_walk() function, we keep a
string_list mapping refnames to their reflog contents. This
serves as a cache so that accessing the same reflog twice
requires only a single copy of the log in memory.
The string_list is initialized via xcalloc, meaning its
strdup_strings field is set to 0. But after inserting a
string into the list, we unconditionally call free() on the
string, leaving the list pointing to freed memory. If
another reflog is added (e.g., "git log -g HEAD HEAD"), then
the second one may have unpredictable results.
The extra free was added by 5026b47175 (add_reflog_for_walk:
avoid memory leak, 2017-05-04). Though if you look
carefully, you can see that the code was buggy even before
then. If we tried to read the reflogs by time but came up
with no entries, we exited with an error, freeing the string
in that code path. So the bug was harder to trigger, but
still there.
We can fix it by just asking the string list to make a copy
of the string. Technically we could fix the problem by not
calling free() on our string (and just handing over
ownership to the string list), but there are enough
conditionals that it's quite hard to figure out which code
paths need the free and which do not. Simpler is better
here.
The new test reliably shows the problem when run with
--valgrind or ASAN.

Since 39ee4c6c2f (branch: record creation of renamed branch
in HEAD's log, 2017-02-20), a rename on the currently
checked out branch will create two entries in the HEAD
reflog: one where the branch goes away (switching to the
null oid), and one where it comes back (switching away from
the null oid).
This confuses the reflog-walk code. When walking backwards,
it first sees the null oid in the "old" field of the second
entry. Thanks to the "root commit" logic added by 71abeb753f
(reflog: continue walking the reflog past root commits,
2016-06-03), we keep looking for the next entry by scanning
the "new" field from the previous entry. But that field is
also null! We need to go just a tiny bit further, and look
at its "old" field. But with the current code, we decide the
reflog has nothing else to show and just give up. To the
user this looks like the reflog was truncated by the rename
operation, when in fact those entries are still there.
This patch does the absolute minimal fix, which is to look
back that one extra level and keep traversing.
The resulting behavior may not be the _best_ thing to do in
the long run (for example, we show both reflog entries each
with the same commit id), but it's a simple way to fix the
problem without risking further regressions.

It seems to be a little-known feature of `grep` (and it certainly came
as a surprise to this here developer who believed to know the Unix tools
pretty well) that multiple patterns can be passed in the same
command-line argument simply by separating them by newlines. Watch, and
learn:
$ printf '1\n2\n3\n' | grep "$(printf '1\n3\n')"
1
3
That behavior also extends to patterns passed via `-e`, and it is not
modified by passing the option `-E` (but trying this with -P issues the
error "grep: the -P option only supports a single pattern").
It seems that there are more old Unix hands who are surprised by this
behavior, as grep invocations of the form
grep "$(git rev-parse A B) C" file
were introduced in a85b377d041 (push: the beginning of "git push
--signed", 2014-09-12), and later faithfully copy-edited in b9459019bbb
(push: heed user.signingkey for signed pushes, 2014-10-22).
Please note that the output of `git rev-parse A B` separates the object
IDs via *newlines*, not via spaces, and those newlines are preserved
because the interpolation is enclosed in double quotes.
As a consequence, these tests try to validate that the file contains
either A's object ID, or B's object ID followed by C, or both. Clearly,
however, what the test wanted to see is that there is a line that
contains all of them.
This is clearly unintended, and the grep invocations in question really
match too many lines.
Fix the test by avoiding the newlines in the patterns.

Update sha1dc from the latest version by the upstream maintainer[1].
See commit 6b851e536b ("sha1dc: update from upstream", 2017-06-06) for
the last update.
This solves the Big Endian detection on Solaris reported against
v2.13.2[2], hopefully without any regressions. A version of this has
been tested on two Solaris SPARC installations, Cygwin (by jturney on
cygwin@Freenode), and on numerous more boring systems (mainly
linux/x86_64). See [3] for a discussion of the implementation and
platform-specific issues.
See commit a0103914c2 ("sha1dc: update from upstream", 2017-05-20) and
6b851e536b ("sha1dc: update from upstream", 2017-06-06) for previous
attempts in the 2.13 series to address various compile-time feature
detection in this library.

The helper function utf8_fprintf(fp, ...) has exactly the same
effect to the output stream fp as fprintf(fp, ...) does, and the
only difference is that its return value counts in display columns
consumed (assuming that the payload is encoded in UTF-8), as opposed
to number of bytes.
There is no reason to call it unless the caller cares about its
return value.

Defining USE_ASCIIDOCTOR=1 when building Git uses asciidoctor over
asciidoc when generating DocBook and man page documentation. However,
the contrib/subtree module does not presently honour that flag.
This causes a build failure when asciidoc is not present on the build
system. Instead, adapt the main Documentation/Makefile logic to use

Since f6ecc62dbf (write_shared_index(): use tempfile module, 2015-08-10)
write_shared_index() has been using mks_tempfile() to create the
temporary file that will become the shared index.
But even before that, it looks like the functions used to create this
file didn't call adjust_shared_perm(), which means that the shared
index file has always been created with 600 permissions regardless
of the shared permission settings.
Because of that, on repositories created with `git init --shared=all`
and using the split index feature, one gets an error like:
fatal: .git/sharedindex.a52f910b489bc462f187ab572ba0086f7b5157de: index file open failed: Permission denied
when another user performs any operation that reads the shared index.

mks_tempfile() ourselves to adjust the permission bits.
