Steffen Prohaska 180787c48f Improved hint on how to set identity
The first thing we teach in the tutorial is to set the default
identity in $HOME/.gitconfig using "git config --global".  The
suggestion in the error message should match the order, while
hinting that per repository identity can later be configured
differently.

David Kastrup b2bc9a3098 git-sh-setup.sh: make GIT_DIR absolute
Quite a few of the scripts are rather careless about using GIT_DIR
while changing directories.

Some try their hands (with different likelihood of success) in making
GIT_DIR absolute.

This patch lets git-sh-setup.sh cater for absolute directories (in a
way that should work reliably also with non-Unix path names) and
removes the respective kludges in git-filter-branch.sh and
git-instaweb.sh.

Alberto Bertogli 0476786e64 Allow git-svnimport to take "" as the trunk directory.
Some repositories started with the trunk in "/" and then moved it to the
standard "trunk/" location.

On these repositories, the correct thing would be to call git-svnimport -T "",
but because of the way the options are handled, it uses the default "trunk"
instead of the given empty string. This patch fixes that behaviour.

Reece H. Dunn 7da660f437 git-p4: Fix the sorting of changelists when cloning a Perforce repository.
When performing a git-p4 clone operation on a Perforce repository,
where the changelists change in order of magnitude (e.g. 100 to 1000),
the set of changes to import from is not sorted properly. This is
because the data in the list is strings not integers. The other place
where this is done already converts the value to an integer, so it is
not affected.

René Scharfe 89d07f750a diff: don't run pager if user asked for a diff style exit code
As Wincent Colaiuta found out, it's a bit unexpected for git diff to
start a pager even when the --quiet option is specified.  The problem
is that the pager hides the return code -- which is the only output
we're interested in in this case.

Push pager setup down into builtin-diff.c and don't start the pager
if --exit-code or --quiet (which implies --exit-code) was specified.

Paul Mackerras 7b459a1c1c gitk: Fix bug introduced in commit 67a4f1a7
In fixing the "can't unset idinlist" error, I moved the setting of
idinlist into the loop that splits the parents into "new" parents
(i.e. those of which this is the first child) and "old" parents.
Unfortunately this is incorrect in the case where we hit the break
statement a few lines further down, since when we come back in,
we'll see idinlist($p) set for some parents that aren't in the list.

This fixes it by moving the loop that sets up newolds and oldolds
further down.

Mark Levedahl 314c30936f [PATCH] gitk: Handle MouseWheel events on Windows
Windows, unlike X-Windows, sends mousewheel events by default to the
window that has keyboard focus and uses the MouseWheel event to do so.
The window to be scrolled must be able to take focus, but gitk's panels
are disabled so cannot take focus.  For all these reasons, a different
design is needed to use the mousewheel on Windows.  The approach here is
to bind the mousewheel events to the top level window and redirect them
based upon the current mouse position.

David Kastrup 4739809cd0 Add support for an info version of the user manual
These patches use docbook2x in order to create an info version of the
git user manual.  No existing Makefile targets (including "all") are
touched, so you need to explicitly say

make info
sudo make install-info

to get git.info created and installed.  If the info target directory
does not already contain a "dir" file, no directory entry is created.
This facilitates $(DESTDIR)-based installations.  The same could be
achieved with

sudo make INSTALL_INFO=: install-info

explicitly.

perl is used for patching up sub-par file and directory information in
the Texinfo file.  It would be cleaner to place the respective info
straight into user-manual.txt or the conversion configurations, but I
find myself unable to find out how to do this with Asciidoc/Texinfo.

As mentioned, the three-way case *should* be as trivial as the
following. It passes all the tests, and I verified that a conflicting
merge in the 100,000 file horror-case merged correctly (with the conflict
markers) in 0.687 seconds with this, so it works, but I'm lazy and
somebody else should double-check it [jc: followed all three-way merge
codepaths and verified it removes when it should].

Without this patch, the merge took 8.355 seconds, so this patch
really does make a huge difference for merge performance with lots and
lots of files, and we're not talking percentages, we're talking
orders-of-magnitude differences!

Now "unpack_trees()" is just fast enough that we don't need to avoid it
(although it's probably still a good idea to eventually convert it to use
the traverse_trees() infrastructure some day - just to avoid having
extraneous tree traversal functions).

Actually, there is another bug nearby.

If you do:

	git bundle create v2.6-20-v2.6.22.bndl v2.6.20..v2.6.22

the bundle records that it requires v2.6.20^0 commit (correct)
and gives you tag v2.6.22 (incorrect); the bug is that the
object it lists in fact is the commit v2.6.22^0, not the tag.

This is because the revision range operation .. is always about
set of commits, but the code near where my patch touches does
not validate that the sha1 value obtained from dwim_ref()
against the commit object name e->item->sha1 before placing the
head information in the commit.

The attached patch attempts to fix this problem.

Linus Torvalds d699676dda Optimize the two-way merge of git-read-tree too
This trivially optimizes the two-way merge case of git-read-tree too,
which affects switching branches.

When you have tons and tons of files in your repository, but there are
only small differences in the branches (maybe just a couple of files
changed), the biggest cost of the branch switching was actually just the
index calculations.

This fixes it (timings for switching between the "testing" and "master"
branches in the 100,000 file testing-repo-from-hell, where the branches
only differ in one small file).

Before:
	[torvalds@woody bummer]$ time git checkout master
	real    0m9.919s
	user    0m8.461s
	sys     0m0.264s

After:
	[torvalds@woody bummer]$ time git checkout testing
	real    0m0.576s
	user    0m0.348s
	sys     0m0.228s

so it's easily an order of magnitude different.

This concludes the series. I think we could/should do the three-way merge
too (to speed up merges), but I'm lazy. Somebody else can do it.

The rule is very simple: you need to remove the old entry if:
 - you want to remove the file entirely
 - you replace it with a "merge conflict" entry (ie a non-stage-0 entry)

and you can avoid removing it if you either

 - keep the old one
 - or resolve it to a new one.

and these rules should all be valid for the three-way case too.

Linus Torvalds 288f072ec0 Optimize the common cases of git-read-tree
This optimizes bind_merge() and oneway_merge() to not unnecessarily
remove and re-add the old index entries when they can just get replaced
by updated ones.

This makes these operations much faster for large trees (where "large"
is in the 50,000+ file range), because we don't unnecessarily move index
entries around in the index array all the time.

Using the "bummer" tree (a test-tree with 100,000 files) we get:

Before:
	[torvalds@woody bummer]$ time git commit -m"Change one file" 50/500
	real    0m9.470s
	user    0m8.729s
	sys     0m0.476s

After:
	[torvalds@woody bummer]$ time git commit -m"Change one file" 50/500
	real    0m1.173s
	user    0m0.720s
	sys     0m0.452s

Linus Torvalds 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

	real    0m14.273s
	user    0m1.312s

(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).

Junio C Hamano 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.

Linus Torvalds 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.

Uwe Kleine-König 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
  mail.

- 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.

Email::Valid does respect this considering such a mailbox specification
invalid.  b06c6bc831 addressed the issue, but
only if Email::Valid is available.

Shawn O. Pearce 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.

Shawn O. Pearce 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.

Shawn O. Pearce 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".
