If the user enables untracked cache, then
- move worktree to an unsupported filesystem
- or simply upgrade OS
- or move the whole (portable) disk from one machine to another
- or access a shared fs from another machine
there's no guarantee that untracked cache can still function properly.
Record the worktree location and OS footprint in the cache. If it
changes, err on the safe side and disable the cache. The user can
'update-index --untracked-cache' again to make sure all conditions are
met.
This adds a new requirement that setup_git_directory* must be called
before read_cache() because we need worktree location by then, or the
cache is dropped.
This change does not cover all bases, you can fool it if you try
hard. The point is to stop accidents.

Overall time saving on "git status" is about 40% in the best case
scenario, removing ..collect_untracked() as the most time consuming
function. read and refresh index operations are now at the top (which
should drop when index-helper and/or watchman support is added). More
numbers and analysis below.

Index version 4 in split index mode and cache-tree populated. No

This is after enabling untracked cache and the cache is still empty.
We see a slight increase in .._collect_untracked() and update_index
(because new cache has to be written to $GIT_DIR/index).

If we are expiring reflog entries for a symbolic reference, then how
should --updateref be handled if the newest reflog entry is expired?
Option 1: Update the referred-to reference. (This is what the current
code does.) This doesn't make sense, because the referred-to reference
has its own reflog, which hasn't been rewritten.
Option 2: Update the symbolic reference itself (as in, REF_NODEREF).
This would convert the symbolic reference into a non-symbolic
reference (e.g., detaching HEAD), which is surely not what a user
would expect.
Option 3: Error out. This is plausible, but it would make the
following usage impossible:
git reflog expire ... --updateref --all
Option 4: Ignore --updateref for symbolic references.
We choose to implement option 4.
Note: another problem in this code will be fixed in a moment.

The documentation of 'git submodule update' has several problems:
1) It mentions that value 'none' of submodule.$name.update can be
overridden by --checkout, but other combinations of configuration
values and command line options are not mentioned.
2) The documentation of submodule.$name.update is scattered across three
places, which is confusing.
3) The documentation of submodule.$name.update in gitmodules.txt is
incorrect, because the code always uses the value from .git/config
and never from .gitmodules.
4) Documentation of --force was incomplete, because it is only effective
in case of checkout method of update.
Fix all these problems by documenting submodule.*.update in
git-submodule.txt and make everybody else refer to it.

Extending the js/push-to-deploy topic, the behaviour of "git push"
when updating the working tree and the index with an update to the
branch that is checked out can be tweaked by push-to-checkout hook.
* jc/push-to-checkout:
receive-pack: support push-to-checkout hook
receive-pack: refactor updateInstead codepath

"git push" has been taught a "--atomic" option that makes push to
update more than one ref an "all-or-none" affair.
* sb/atomic-push:
Document receive.advertiseatomic
t5543-atomic-push.sh: add basic tests for atomic pushes
push.c: add an --atomic argument
send-pack.c: add --atomic command line argument
send-pack: rename ref_update_to_be_sent to check_to_send_update
receive-pack.c: negotiate atomic push support
receive-pack.c: add execute_commands_atomic function
receive-pack.c: move transaction handling in a central place
receive-pack.c: move iterating over all commands outside execute_commands
receive-pack.c: die instead of error in case of possible future bug
receive-pack.c: shorten the execute_commands loop over all commands

"git log --invert-grep --grep=WIP" will show only commits that do
not have the string "WIP" in their messages.
* cj/log-invert-grep:
log: teach --invert-grep option

Like the "clone" subcommand, allow excluding subdirectories in the
"sync" subcommand.
* ld/p4-exclude-in-sync:
git-p4: support excluding paths on sync
|
|
The clone subcommand has long had support for excluding
subdirectories, but sync has not. This is a nuisance,
since as soon as you do a sync, any changed files that
were initially excluded start showing up.
Move the "exclude" command-line option into the parent
class; the actual behavior was already present there so
it simply had to be exposed.

By default, a patch that affects outside the working area (either a
Git controlled working tree, or the current working directory when
"git apply" is used as a replacement of GNU patch) is rejected as a
mistake (or a mischief). Git itself does not create such a patch,
unless the user bends over backwards and specifies a non-standard
prefix to "git diff" and friends.
When `git apply` is used as a "better GNU patch", the user can pass
the `--unsafe-paths` option to override this safety check. This
option has no effect when `--index` or `--cached` is in use.
The new test was stolen from Jeff King with slight enhancements.
Note that a few new tests for touching outside the working area by
following a symbolic link are still expected to fail at this step,
but will be fixed in later steps.

We may want to say something about command line option names in the
new section as well, but for now, let's make sure everybody is clear
on how to structure and name their configuration variables.
The text for the rules are partly taken from the log message of
Jonathan's 6b3020a2 (add: introduce add.ignoreerrors synonym for
add.ignore-errors, 2010-12-01).

It seems to be a common mistake to try using a single remote
(e.g. 'origin') to fetch from one place (i.e. upstream) while
pushing to another (i.e. your publishing point).
That will never work satisfactorily, and it is easy to understand
why if you think about what refs/remotes/origin/* would mean in such
a world. It fundamentally cannot reflect the reality. If it
follows the state of your upstream, it cannot match what you have
published, and vice versa.
It may be that misinformation is spread by some people. Let's
counter them by adding a few words to our documentation.
- The description was referring to <oldurl> and <newurl>, but never
mentioned <name> argument you give from the command line. By
mentioning "remote <name>", stress the fact that it is configuring
a single remote.
- Add a reminder that explicitly states that this is about a single
remote, which the triangular workflow is not about.

b6d8f309 (diff-raw format update take #2., 2005-05-23) started
documenting the diff format, and it said
...
(8) sha1 for "dst"; 0{40} if creation, unmerged or "look at work tree".
(9) status, followed by similarlity index number only for C and R.
(10) a tab or a NUL when '-z' option is used.
...
because C and R _were_ the only ones that came with a number back
then. This was corrected by ddafa7e9 (diff-helper: Fix R/C score
parsing under -z flag., 2005-05-29) and we started saying "score"
instead of "similarlity index" (because we can have other kind of
score there), and stopped saying "only for C and R" (because Git is
an ever evolving system). Later f345b0a0 (Add -B flag to diff-*
brothers., 2005-05-30) introduced a new concept, "dissimilarity"
score; it did not have to fix any documentation.
The current text that says only C and R can have scores came
independently from a5a323f3 (Add reference for status letters in
documentation., 2008-11-02) and it was wrong from the day one.
