22631473e0 Fix "git commit directory/" performance anomaly
This trivial patch avoids re-hashing files that are already clean in the
index. This mirrors what commit 0781b8a9b2
did for "git add .", only for "git commit ." instead.

This improves the cold-cache case immensely, since we don't need to bring
in all the file contents, just the index and any files dirty in the index.

Before:

	[torvalds@woody linux]$ time git commit .
	real    1m49.537s
	user    0m3.892s
	sys     0m2.432s

After:

	[torvalds@woody linux]$ time git commit .
	real    0m14.273s
	user    0m1.312s
	sys     0m0.516s

(both after doing a "echo 3 > /proc/sys/vm/drop_caches" to get cold-cache
behaviour - even with the index optimization git still has to "lstat()"
all the files, so with a truly cold cache, bringing all the inodes in
will take some time).

[jc: trivial "return 0;" fixed]

af3785dc5a Optimize "diff --cached" performance.
The read_tree() function is called only from the call chain to
run "git diff --cached" (this includes the internal call made by
git-runstatus to run_diff_index()).  The function vacates stage
without any funky "merge" magic.  The caller then goes and
compares stage #1 entries from the tree with stage #0 entries
from the original index.

When adding the cache entries this way, it used the general
purpose add_cache_entry().  This function looks for an existing
entry to replace or if there is none to find where to insert the
new entry, resolves D/F conflict and all the other things.

For the purpose of reading entries into an empty stage, none of
that processing is needed.  We can instead append everything and
then sort the result at the end.

This commit changes read_tree() to first make sure that there is
no existing cache entries at specified stage, and if that is the
case, it runs add_cache_entry() with ADD_CACHE_JUST_APPEND flag
(new), and then sort the resulting cache using qsort().

This new flag tells add_cache_entry() to omit all the checks
such as "Does this path already exist?  Does adding this path
remove other existing entries because it turns a directory to a
file?" and instead append the given cache entry straight at the
end of the active cache.  The caller of course is expected to
sort the resulting cache at the end before using the result.

933bf40a5c Start moving unpack-trees to "struct tree_desc"
This doesn't actually change any real code, but it changes the interface
to unpack_trees() to take an array of "struct tree_desc" entries, the same
way the tree-walk.c functions do.

The reason for this is that we would be much better off if we can do the
tree-unpacking using the generic "traverse_trees()" functionality instead
of having to the special "unpack" infrastructure.

This really is a pretty minimal diff, just to change the calling
convention. It passes all the tests, and looks sane. There were only two
users of "unpack_trees()": builtin-read-tree and merge-recursive, and I
tried to keep the changes minimal.

94638f89f5 send-email: get all the quoting of realnames right
- when sending several mails I got a slightly different behaviour for the first
  mail compared to the second to last one.  The reason is that $from was
  assigned in line 608 and was not reset when beginning to handle the next

- Email::Valid can only handle properly quoted real names, so quote arguments
  to extract_valid_address.

This patch cleans up variable naming to better differentiate between sender of
the mail and it's author.

cabead982b Use the empty tree for base diff in paranoid-update on new branches
We have to load a tree difference for the purpose of testing
file patterns.  But if our branch is being created and there is no
specific base to difference against in the rule our base will be
'0'x40.  This is (usually) not a valid tree-ish object in a Git
repository, so there's nothing to difference against.

Instead of creating the empty tree and running git-diff against
that we just take the output of `ls-tree -r --name-only` and mark
every returned pathname as an add.

d47eed3272 Teach the update-paranoid to look at file differences
In some applications of the update hook a user may be allowed to
modify a branch, but only if the file level difference is also an
allowed change.  This is the commonly requested feature of allowing
users to modify only certain files.

A new repository.*.allow syntax permits granting the three basic
file level operations:

  A: file is added relative to the other tree
  M: file exists in both trees, but its SHA-1 or mode differs
  D: file is removed relative to the other tree

on a per-branch and path-name basis.  The user must also have a
branch level allow line already granting them access to create,
rewind or update (CRU) that branch before the hook will consult
any file level rules.

In order for a branch change to succeed _all_ files that differ
relative to some base (by default the old value of this branch,
but it can also be any valid tree-ish) must be allowed by file
level allow rules.  A push is rejected if any diff exists that
is not covered by at least one allow rule.

b767c792fa Teach update-paranoid how to store ACLs organized by groups
In some applications of this paranoid update hook the set of ACL
rules that need to be applied to a user can be large, and the
number of users that those rules must also be applied to can be
more than a handful of individuals.  Rather than repeating the same
rules multiple times (once for each user) we now allow users to be
members of groups, where the group supplies the list of ACL rules.
For various reasons we don't depend on the underlying OS groups
and instead perform our own group handling.

Users can be made a member of one or more groups by setting the
user.memberOf property within the "users/$who.acl" file:

  [user]
    memberOf = developer
	memberOf = administrator

This will cause the hook to also parse the "groups/$groupname.acl"
file for each value of user.memberOf, and merge any allow rules
that match the current repository with the user's own private rules
(if they had any).

Since some rules are basically the same but may have a component
differ based on the individual user, any user.* key may be inserted
into a rule using the "${user.foo}" syntax.  The allow rule does
not match if the user does not define one (and exactly one) value
for the key "foo".

cad3a2056d pager: find out pager setting from configuration
It was very unfortunate that we added core.pager setting to the
configuration file; even when the underlying command does not care
if there is no git repository is involved (think "git diff --no-index"),
the user would now rightfully want the configuration setting to be
honored, which means we would need to read the configuration file before
we launch the pager.

This is a minimum change in the sense that it restores the old
behaviour of not even reading config in setup_git_directory(),
but have the core.pager honored when we know it matters.

Note that this does not cover "git -p --git-dir where command";
the -p option immediately trigger the pager settings before we
even see --git-dir to learn where the configuration file is, so
we will end up reading the configuration from the place where
we would _normally_ find the git repository.

33a798c880 setup.c:verify_non_filename(): don't die unnecessarily while disambiguating
If you have a working tree _file_ "foo", attempt to refer to a
branch "foo/bar" without -- to disambiguate, like this:

	$ git log foo/bar

tried to make sure that foo/bar cannot be naming a working tree
file "foo/bar" (in which case we would say "which one do you
want?  A rev or a working tree file?  clarify with -- please").
We run lstat("foo/bar") to check that.  If it does not succeed,
there is no ambiguity.

That is good.  But we also checked the error status for the
lstat() and expected it to fail with ENOENT.  In this particular
case, however, it fails with ENOTDIR.  That should be treated as
"expected error" as well.

936492d3cf unpack-trees.c: assume submodules are clean during check-out
Sven originally raised this issue:

    If you have a submodule checked out and you go back (or
    forward) to a revision of the supermodule that contains a
    different revision of the submodule and then switch to
    another revision, it will complain that the submodule is not
    uptodate, because git simply didn't update the submodule in
    the first move.

The current policy is to consider it is perfectly normal that
checked-out submodule is out-of-sync wrt the supermodule index.
At least until we introduce a superproject repository
configuration option that says "in this repository, I do care
about this submodule and at any time I move around in the
superproject, recursively check out the submodule to match", it
is a reasonable policy, as we currently do not recursively
checkout the submodules at all.  The most extreme case of this
policy is that the superproject index knows about the submodule
but the subdirectory does not even have to be checked out.

The function verify_uptodate(), called during the two-way merge
aka branch switching, is about "make sure the filesystem entity
that corresponds to this cache entry is up to date, lest we lose
the local modifications".  As we explicitly allow submodule
checkout to drift from the supermodule index entry, the check
should say "Ok, for submodules, not matching is the norm" for
now.

Later when we have the ability to mark "I care about this
submodule to be always in sync with the superproject" (thereby
implementing automatic recursive checkout and perhaps diff,
among other things), we should check if the submodule in
question is marked as such and perform the current test.

OS X sends Button-2 on a "real" right click, such as with a three
button mouse, or by using the two-finger trackpad click.

a697ec69cb Fix bogus use of printf in t3700 test
The hashed contents did not matter in the end result, but it passed
an uninitialized variable to printf, which caused it to emit empty
while giving an error/usage message.

d20602eec9 gitweb: do not choke on recursive symlink
If somebody used to advertise his repository that physically
resides at /pub/lic.git/ as:

	git://git.example.com/pub/lic.git/

but now wants to use --base-path to allow:

	git://git.example.com/lic.git/

she can start git-daemon with --base-path option, like this:

	git-daemon --base-path=/pub --export-all

During the transition, however, she would also want to allow
older URL as well.  One natural way to achieve that is to create
a symlink:

	ln -s /pub /pub/pub

so that a request to git://git.example.com/pub/lic.git/ is first
translated by --base-path to a request to /pub/pub/lic.git/
which goes to /pub/lic.git, thanks to the symlink.

So far so good.

However, gitweb chokes if there is such a symlink (File::Find
barfs with "/pub/pub is a recursive symbolic link").  Make the
code ignore such a symlink.

a13ee29b97 git-gui: Avoid Tcl error in popup menu on diff viewer
If there is no path currently shown in the diff viewer then we
were getting Tcl errors anytime the user right-clicked on the
diff viewer to bring up its popup menu.  The bug here is caused
by trying to get the file_state for the empty string; this path
is never seen so we never have file_state for it.  In such cases
we now disable the Stage Hunk For Commit option.
