"git gc --auto" was recently changed to run in the background to
give control back early to the end-user sitting in front of the

"git remote rm" and "git remote prune" can involve removing many

submodule.*.ignore and diff.ignoresubmodules are used to ignore all

Changing get_next_line() to return the end pointer instead of NULL in
case no newline character is found treats allows us to treat complete
and incomplete lines the same, simplifying the code. Switching to
counting lines instead of EOLs allows us to start counting at the
first character, instead of having to call get_next_line() first.

We currently have pack.writeBitmaps, which originally
operated at the pack-objects level. This should really have
been a repack.* option from day one. Let's give it the more
sensible name, but keep the old version as a deprecated
synonym.

We previously needed to pass --no-write-bitmap-index
explicitly to pack-objects to override its reading of
pack.writebitmaps from the config. Now that it no longer
does so, we can assume that bitmaps are off by default, and
only turn them on when necessary. This also lets us avoid a
confusing tri-state flag for write_bitmaps.

The handling of the pack.writebitmaps config option
originally happened in pack-objects, which is quite
low-level. It would make more sense for drivers of
pack-objects to read the config, and then manipulate
pack-objects with command-line options.
Recently, repack learned to do so, making the low-level read
of pack.writebitmaps redundant here. Other callers, like
upload-pack, would not generally want to write bitmaps
anyway.
This could be considered a regression for somebody who is
driving pack-objects themselves outside of repack and
expects the config option to be used. However, such users
seem rather unlikely given how new the bitmap code is (and
the fact that they would basically be reimplementing repack
in the first place).
Note that we do not do anything with pack.writeBitmapHashCache
here. That option is not about "do we write bimaps", but
rather "when we are writing bitmaps, how do we do it?". You
would want that to kick in anytime you decide to write them,
similar to how pack.indexVersion is used.

The config option to turn on bitmaps is read all the way
down in the plumbing of pack-objects. This makes it hard for
other options in the porcelain of repack to make decisions
based on the bitmap setting. For example,
repack.packKeptObjects tries to kick in by default only when
bitmaps are turned on. But it can't do so reliably because
it doesn't yet know whether we are using bitmaps.
This patch teaches repack to respect pack.writebitmaps. It
means we pass a redundant command-line flag to pack-objects,
but that's OK; it shouldn't affect the outcome.

Commit ee34a2b (repack: add `repack.packKeptObjects` config
var, 2014-03-03) added a flag which could duplicate kept
objects, but did not mean to turn it on by default. Instead,
the option is tied by default to the decision to write
bitmaps, like:
if (pack_kept_objects < 0)
pack_kept_objects = write_bitmap;
after which we expect pack_kept_objects to be a boolean 0 or
1. However, that assignment neglects that write_bitmap is
_also_ a tri-state with "-1" as the default, and with
neither option given, we accidentally turn the option on.
This patch is the minimal fix to restore the desired
behavior for the default state. Further patches will fix the
more complicated cases.
Note the update to t7700. It failed to turn on bitmaps,
meaning we were actually confirming the wrong behavior!

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.

Since the introduction of opportunisitic updates of remote-tracking
branches, started at around f2690487 (fetch: opportunistically
update tracking refs, 2013-05-11) with a few updates in v1.8.4 era,
the remote.*.fetch configuration always kicks in even when a refspec
to specify what to fetch is given on the command line, and there is
no way to disable or override it per-invocation.
Teach the command to pay attention to the --refmap=<lhs>:<rhs>
command-line options that can be used to override the use of
configured remote.*.fetch as the refmap.

Running "git update-index --cacheinfo" without any further
arguments results in a segfault rather than an error
message. Commit ec160ae (update-index: teach --cacheinfo a
new syntax "mode,sha1,path", 2014-03-23) added code to
examine the format of the argument, but forgot to handle the
NULL case.
Returning an error from the parser is enough, since we then
treat it as an old-style "--cacheinfo <mode> <sha1> <path>",
and complain that we have less than 3 arguments to read.

Read-only operations such as "git status" that internally refreshes
the index write out the refreshed index to the disk to optimize
future accesses to the working tree, but this could race with a
"read-write" operation that modify the index while it is running.
Detect such a race and avoid overwriting the index.
Duy raised a good point that we may need to do the same for the
normal writeout codepath, not just the "opportunistic" update
codepath. While that is true, nobody sane would be running two
simultaneous operations that are clearly write-oriented competing
with each other against the same index file. So in that sense that
can be done as a less urgent follow-up for this topic.
