Patch id changes if users reorder file diffs that make up a patch.
As the result is functionally equivalent, a different patch id is
surprising to many users.
In particular, reordering files using diff -O is helpful to make patches
more readable (e.g. API header diff before implementation diff).
Add an option to change patch-id behaviour making it stable against
these kinds of patch change:
calculate SHA1 hash for each hunk separately and sum all hashes
(using a symmetrical sum) to get patch id
We use a 20byte sum and not xor - since xor would give 0 output
for patches that have two identical diffs, which isn't all that
unlikely (e.g. append the same line in two places).
The new behaviour is enabled
- when patchid.stable is true
- when --stable flag is present
Using a new flag --unstable or setting patchid.stable to false force
the historical behaviour.
In the documentation, clarify that patch ID can now be a sum of hashes,
not a hash.
Document how command line and config options affect the
behaviour.

Running "git update-index --cacheinfo" without any further

Returning an error from the parser is enough, since we then

When looking for the index of a specfic string in that array, simply
use strcmp() instead of memcmp(). This avoids running over the end of

9f673f9 (gc: config option for running --auto in background -
2014-02-08) puts "gc --auto" in background to reduce user's wait
time. Part of the garbage collecting is pack-refs and pruning
reflogs. These require locking some refs and may abort other processes
trying to lock the same ref. If gc --auto is fired in the middle of a
script, gc's holding locks in the background could fail the script,
which could never happen before 9f673f9.
Keep running pack-refs and "reflog --prune" in foreground to stop
parallel ref updates. The remaining background operations (repack,
prune and rerere) should not impact running git processes.

When 'git remote prune' was used to delete many refs in a repository

When 'git remote rm' or 'git remote prune' were used in a repository
with many refs, and needed to delete many remote-tracking refs, a lot
of time was spent deleting those refs since for each deleted ref,
repack_without_refs() was called to rewrite packed-refs without just
that deleted ref.
To avoid this, call repack_without_refs() first to repack without all
the refs that will be deleted, before calling delete_ref() to delete
each one completely. The call to repack_without_ref() in delete_ref()
then becomes a no-op, since packed-refs already won't contain any of

this at least reduces the number of such dependencies by one. Finally
change two places in refs.c itself to use the new function to check if a ref

Git generally changes directory to the repository root on

We currently do this chdir manually, but we can ask
run_command to do it for us. This is fewer lines of code,
and as a bonus, the chdir is limited to the child process,

Right now we pass off the string found by "--date" straight
to the fmt_ident function, which will use our strict

things like "--date=now" or "--date=2.days.ago" will not
work.
Instead, let's fallback to the approxidate function to
handle this for us. Note that we must try parse_date
ourselves first, even though approxidate will try strict
parsing itself. The reason is that approxidate throws away
any timezone information it sees from the strict parsing,
and we want to preserve it. So asking for:
git commit --date="@1234567890 -0700"
continues to set the date in -0700, regardless of what the

The previous implementation used a single sorted linear list of blame
entries for organizing all partial or completed work. Every subtask had
to scan the whole list, with most entries not being relevant to the
task. The resulting run-time was quadratic to the number of separate
chunks.
This change gives every subtask its own data to work with. Subtasks are
organized into "struct origin" chains hanging off particular commits.
Commits are organized into a priority queue, processing them in commit
date order in order to keep most of the work affecting a particular blob

When we pick another commit's message, we die() immediately
if we find that it's empty and we are not going to run an
editor (i.e., when running "-C" instead of "-c"). However,
this check is redundant and harmful.
It's redundant because we will already notice the empty
message later, after we would have run the editor, and die
there (just as we would for a regular, not "-C" case, where
the user provided an empty message in the editor).
It's harmful for a few reasons:
1. It does not respect --allow-empty-message. As a result,
a "git rebase -i" cannot "pick" such a commit. So you
cannot even go back in time to fix it with a "reword"
or "edit" instruction.
2. It does not take into account other ways besides the
editor to modify the message. For example, "git commit
-C empty-commit -m foo" could take the author
information from empty-commit, but add a message to it.
There's more to do to make that work correctly (and
right now we explicitly forbid "-C with -m"), but this
removes one roadblock.
3. The existing check is not enough to prevent segfaults.
We try to find the "\n\n" header/body boundary in the
commit. If it is at the end of the string (i.e., no
body), _or_ if we cannot find it at all (i.e., a
truncated commit object), we consider the message
empty. With "-C", that's OK; we die in either case. But
with "-c", we continue on, and in the case of a
truncated commit may end up dereferencing NULL+2.

Command `git blame --date relative` aligns the date field with a
fixed-width (defined by blame_date_width), and if time_str is shorter
than that, it adds spaces for padding. But there are two bugs in the
following codes:
time_len = strlen(time_str);
...
memset(time_buf + time_len, ' ', blame_date_width - time_len);
1. The type of blame_date_width is size_t, which is unsigned. If
time_len is greater than blame_date_width, the result of
"blame_date_width - time_len" will never be a negative number, but a
really big positive number, and will cause memory overwrite.
This bug can be triggered if either l10n message for function
show_date_relative() in date.c is longer than 30 characters, then
`git blame --date relative` may exit abnormally.
2. When show blame information with relative time, the UTF-8 characters
in time_str will break the alignment of columns after the date field.
This is because the time_buf padding with spaces should have a
constant display width, not a fixed strlen size. So we should call
utf8_strwidth() instead of strlen() for width calibration.

Since almost all comments for l10n translators are marked with the same
prefix (tag): "TRANSLATORS:", it's safe to only extract comments with
this special tag. I.E. it's better to call xgettext as:
xgettext --add-comments=TRANSLATORS: ...
Also tweaks the multi-line comment in "init-db.c", to make it start with
the proper tag, not "* TRANSLATORS:" (which has a star before the tag).

Multi-threaing of index-pack was disabled with c0f8654
(index-pack: Disable threading on cygwin - 2012-06-26), because
pread() implementations for Cygwin and MSYS were not thread
safe. Recent Cygwin does offer usable pread() and we enabled
multi-threading with 103d530f (Cygwin 1.7 has thread-safe pread,
2013-07-19).
Work around this problem on platforms with a thread-unsafe
pread() emulation by opening one file handle per thread; it
would prevent parallel pread() on different file handles from
stepping on each other.
Also remove NO_THREAD_SAFE_PREAD that was introduced in c0f8654
because it's no longer used anywhere.
This workaround is unconditional, even for platforms with
thread-safe pread() because the overhead is small (a couple file
handles more) and not worth fragmenting the code.

It is a common mistake to call read(2)/pread(2) and forget to
anticipate that they may return error with EAGAIN/EINTR when the
system call is interrupted.
We have xread() helper to relieve callers of read(2) from having to
worry about it; add xpread() helper to do the same for pread(2).
Update the caller in the builtin/index-pack.c and the mmap emulation
in compat/.

This change is mostly clerical: the parse_cmd_*() functions need to
use local variables rather than a struct ref_update to collect the
arguments needed for each update, and then call ref_transaction_*() to
queue the change rather than building up the list of changes at the
caller side.
