9f765ce62f remote.c: introduce branch.<name>.pushremote
This new configuration variable overrides `remote.pushdefault` and
`branch.<name>.remote` for pushes.  When you pull from one
place (e.g. your upstream) and push to another place (e.g. your own
publishing repository), you would want to set `remote.pushdefault` to
specify the remote to push to for all branches, and use this option to
override it for a specific branch.

versions of "git fetch" that allow an exact object name (likely to

have been advertised due to transfer.hiderefs configuration.

daebaa7813 upload/receive-pack: allow hiding ref hierarchies
A repository may have refs that are only used for its internal
bookkeeping purposes that should not be exposed to the others that
come over the network.

Teach upload-pack to omit some refs from its initial advertisement
by paying attention to the uploadpack.hiderefs multi-valued
configuration variable.  Do the same to receive-pack via the
receive.hiderefs variable.  As a convenient short-hand, allow using
transfer.hiderefs to set the value to both of these variables.

Any ref that is under the hierarchies listed on the value of these
variable is excluded from responses to requests made by "ls-remote",
"fetch", etc. (for upload-pack) and "push" (for receive-pack).

Because these hidden refs do not count as OUR_REF, an attempt to
fetch objects at the tip of them will be rejected, and because these
refs do not get advertised, "git push :" will not see local branches
that have the same name as them as "matching" ones to be sent.

An attempt to update/delete these hidden refs with an explicit
refspec, e.g. "git push origin :refs/hidden/22", is rejected.  This
is not a new restriction.  To the pusher, it would appear that there
is no such ref, so its push request will conclude with "Now that I
sent you all the data, it is time for you to update the refs.  I saw
that the ref did not exist when I started pushing, and I want the
result to point at this commit".  The receiving end will apply the
compare-and-swap rule to this request and rejects the push with
"Well, your update request conflicts with somebody else; I see there
is such a ref.", which is the right thing to do. Otherwise a push to
a hidden ref will always be "the last one wins", which is not a good
default.

fa23348e95 doc: mention tracking for pull.default
When looking at a configuration file edited long time ago, a user
may find 'pull.default = tracking' and wonder what it means, but
earlier we stopped mentioning this value, even though the code still
support it and more importantly, we have no intention to force old
timers to update their configuration files.

Instead of not mentioning it, add it to the description in a way
that makes it clear that users have no reason to add new uses of it
preferring over 'upstream', by not listing it as a separate item on
the same footing as other values but as a deprecated synonym of the
'upstream' in its description.

75e5c0dc55 push: introduce REJECT_FETCH_FIRST and REJECT_NEEDS_FORCE
When we push to update an existing ref, if:

 * the object at the tip of the remote is not a commit; or
 * the object we are pushing is not a commit,

it won't be correct to suggest to fetch, integrate and push again,
as the old and new objects will not "merge".  We should explain that
the push must be forced when there is a non-committish object is
involved in such a case.

If we do not have the current object at the tip of the remote, we do
not even know that object, when fetched, is something that can be
merged.  In such a case, suggesting to pull first just like
non-fast-forward case may not be technically correct, but in
practice, most such failures are seen when you try to push your work
to a branch without knowing that somebody else already pushed to
update the same branch since you forked, so "pull first" would work
as a suggestion most of the time.  And if the object at the tip is
not a commit, "pull first" will fail, without making any permanent
damage.  As a side effect, it also makes the error message the user
will get during the next "push" attempt easier to understand, now
the user is aware that a non-commit object is involved.

In these cases, the current code already rejects such a push on the
client end, but we used the same error and advice messages as the
ones used when rejecting a non-fast-forward push, i.e. pull from
there and integrate before pushing again.

Introduce new rejection reasons and reword the messages
appropriately.

c08e4d5b5c Enable minimal stat checking
Specifically the fields uid, gid, ctime, ino and dev are set to zero
by JGit. Other implementations, eg. Git in cygwin are allegedly also
somewhat incompatible with Git For Windows and on *nix platforms
the resolution of the timestamps may differ.

Any stat checking by git will then need to check content, which may
be very slow, particularly on Windows. Since mtime and size
is typically enough we should allow the user to tell git to avoid
checking these fields if they are set to zero in the index.

This change introduces a core.checkstat config option where the
the user can select to check all fields (default), or just size
and the whole second part of mtime (minimal).

eff80a9fd9 Allow custom "comment char"
Some users do want to write a line that begin with a pound sign, #,
in their commit log message.  Many tracking system recognise
a token of #<bugid> form, for example.

The support we offer these use cases is not very friendly to the end
users.  They have a choice between

 - Don't do it.  Avoid such a line by rewrapping or indenting; and

 - Use --cleanup=whitespace but remove all the hint lines we add.

Give them a way to set a custom comment char, e.g.

    $ git -c core.commentchar="%" commit

so that they do not have to do either of the two workarounds.

06b1abb5bd submodule update: add --remote for submodule's upstream changes
The current `update` command incorporates the superproject's gitlinked
SHA-1 ($sha1) into the submodule HEAD ($subsha1).  Depending on the
options you use, it may checkout $sha1, rebase the $subsha1 onto
$sha1, or merge $sha1 into $subsha1.  This helps you keep up with
changes in the upstream superproject.

However, it's also useful to stay up to date with changes in the
upstream subproject.  Previous workflows for incorporating such
changes include the ungainly:

  $ git submodule foreach 'git checkout $(git config --file $toplevel/.gitmodules submodule.$name.branch) && git pull'

With this patch, all of the useful functionality for incorporating
superproject changes can be reused to incorporate upstream subproject
updates.  When you specify --remote, the target $sha1 is replaced with
a $sha1 of the submodule's origin/master tracking branch.  If you want
to merge a different tracking branch, you can configure the
`submodule.<name>.branch` option in `.gitmodules`.  You can override
the `.gitmodules` configuration setting for a particular superproject
by configuring the option in that superproject's default configuration
(using the usual configuration hierarchy, e.g. `.git/config`,
`~/.gitconfig`, etc.).

Previous use of submodule.<name>.branch
=======================================

Because we're adding a new configuration option, it's a good idea to
check if anyone else is already using the option.  The foreach-pull
example above was described by Ævar in

    git-submodule foreach: Add $toplevel variable

Gerrit uses the same interpretation for the setting, but because
Gerrit has direct access to the subproject repositories, it updates
the superproject repositories automatically when a subproject changes.
Gerrit also accepts the special value '.', which it expands into the
superproject's branch name.

Although the --remote functionality is using `submodule.<name>.branch`
slightly differently, the effect is the same.  The foreach-pull
example uses the option to record the name of the local branch to
checkout before pulls.  The tracking branch to be pulled is recorded
in `.git/modules/<name>/config`, which was initialized by the module
clone during `submodule add` or `submodule init`.  Because the branch
name stored in `submodule.<name>.branch` was likely the same as the
branch name used during the initial `submodule add`, the same branch
will be pulled in each workflow.

Implementation details
======================

In order to ensure a current tracking branch state, `update --remote`
fetches the submodule's remote repository before calculating the
SHA-1.  However, I didn't change the logic guarding the existing fetch:

  if test -z "$nofetch"
  then
    # Run fetch only if $sha1 isn't present or it
    # is not reachable from a ref.
    (clear_local_git_env; cd "$path" &&
      ( (rev=$(git rev-list -n 1 $sha1 --not --all 2>/dev/null) &&
       test -z "$rev") || git-fetch)) ||
    die "$(eval_gettext "Unable to fetch in submodule path '\$path'")"
  fi

There will not be a double-fetch, because the new $sha1 determined
after the `--remote` triggered fetch should always exist in the
repository.  If it doesn't, it's because some racy process removed it
from the submodule's repository and we *should* be re-fetching.
