"items" array (which would consitute the bulk of the
allocated memory).
This patch adds a helper which frees all of the entries and

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

So this patch should be a noop in terms of behavior, but it

The add_reflog_for_walk() function keeps a cache mapping

Since 5026b47175 (add_reflog_for_walk: avoid memory leak,

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).

reflog-walk: duplicate strings in complete_reflogs list
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.

reflog-walk: skip over double-null oid due to HEAD rename
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.

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.

send-email: --batch-size to work around some SMTP server limit
Some email servers (e.g. smtp.163.com) limit the number emails to be
sent per session (connection) and this will lead to a faliure when
sending many messages.
Teach send-email to disconnect after sending a number of messages
(configurable via the --batch-size=<num> option), wait for a few
seconds (configurable via the --relogin-delay=<seconds> option) and
reconnect, to work around such a limit.
Also add two configuration variables to give these options the default.
Note:
We will use this as a band-aid for now, but in the longer term, we
should look at and react to the SMTP error code from the server;
Xianqiang reports that 450 and 451 are returned by problematic
servers.

sha1collisiondetection: automatically enable when submodule is populated
If a user wants to experiment with the version of collision
detecting sha1 from the submodule, the user needed to not just
populate the submodule but also needed to turn the knob.
A Makefile trick is easy enough to do so, so let's do this. When
somebody with a copy of the submodule populated wants not to use it,
that can be done by overriding it in config.mak or from the command
line.

sha1dc: optionally use sha1collisiondetection as a submodule
Add an option to use the sha1collisiondetection library from the
submodule in sha1collisiondetection/ instead of in the copy in the
sha1dc/ directory.
This allows us to try out the submodule in sha1collisiondetection
without breaking the build for anyone who's not expecting them as we
work out any kinks.

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.
strbuf: change an always NULL/"" strbuf_addftime() param to bool
strbuf_addftime() allows callers to pass a time zone name for
expanding %Z. The only current caller either passes the empty string
or NULL, in which case %Z is handed over verbatim to strftime(3).
Replace that string parameter with a flag controlling whether to
remove %Z from the format specification. This simplifies the code.

apply: use starts_with() in gitdiff_verify_name()
Avoid running over the end of line -- a C string whose length is not
known to this function -- by using starts_with() instead of memcmp(3)
for checking if it starts with "/dev/null". Also simply include the
newline in the string constant to compare against. Drop a comment that

Merge branch 'ks/status-initial-commit'
"git status" has long shown essentially the same message as "git
commit"; the message it gives while preparing for the root commit,
i.e. "Initial commit", was hard to understand for some new users.
Now it says "No commits yet" to stress more on the current status
(rather than the commit the user is preparing for, which is more in
line with the focus of "git commit").

Merge branch 'ab/die-errors-in-threaded'
Traditionally, the default die() routine had a code to prevent it
from getting called multiple times, which interacted badly when a
threaded program used it (one downside is that the real error may
be hidden and instead the only error message given to the user may
end up being "die recursion detected", which is not very useful).
