Fix read-tree merging more than 3 trees using 3-way merge

For multi-base merges, we allowed read-tree -m to take more than
three trees (the last two are our and their branches, and all the
earlier ones, typically one but potentially more, are used as the
merge base). Unfortunately, the conversion done by commit 933bf40
broke this.

attr.c: read .gitattributes from index as well.

This makes .gitattributes files to be read from the index when
they are not checked out to the work tree. This is in line with
the way we always allowed low-level tools to operate in sparsely
checked out work tree in a reasonable way.

It swaps the order of new file creation and converting the blob
to work tree representation; otherwise when we are in the middle
of checking out .gitattributes we would notice an empty but
unwritten .gitattributes file in the work tree and will ignore
the copy in the index.

diff: squelch empty diffs even moreRené Scharfe Tue, 14 Aug 2007 22:41:00 +0000 (00:41 +0200)

diff: squelch empty diffs even more

When we compare two non-tracked files, or explicitly
specify --no-index, the suggestion to run git-status
is not helpful.

The patch adds a new diff_options bitfield member, no_index, that
is used instead of the special value of -2 of the rev_info field
max_count to indicate that the index is not to be used. This makes
it possible to pass that flag down to diffcore_skip_stat_unmatch(),
which only has one diff_options parameter.

This could even become a cleanup if we removed all assignments of
max_count to a value of -2 (viz. replacement of a magic value with
a self-documenting field name) but I didn't dare to do that so late
in the rc game..

The no_index bit, if set, then tells diffcore_skip_stat_unmatch()
to not account for any skipped stat-mismatches, which avoids the
suggestion to run git-status.

merge-recursive: do not rudely die on binary mergeJunio C Hamano Tue, 14 Aug 2007 22:33:07 +0000 (15:33 -0700)

merge-recursive: do not rudely die on binary merge

When you try to merge a path that involves binary file-level
merge, merge-recursive died rudely without cleaning up its own
mess. A files added by the merge were left in the working tree,
but the index was not written out (because it just punted and
died), so it was cumbersome for the user to retry it by first
running "git reset --hard".

This changes merge-recursive to still warn but do the "binary"
merge for such a path; leave the "our" version in the working
tree, but still keep the path unmerged so that the user can sort
it out.

git-diff: squelch "empty" diffsJunio C Hamano Fri, 3 Aug 2007 20:33:31 +0000 (13:33 -0700)

git-diff: squelch "empty" diffs

After starting to edit a working tree file but later when your edit ends
up identical to the original (this can also happen when you ran a
wholesale regexp replace with something like "perl -i" that does not
actually modify many of the paths), "git diff" between the index and the
working tree outputs many "empty" diffs that show "diff --git" headers
and nothing else, because these paths are stat-dirty. While it was a
way to warn the user that the earlier action of the user made the index
ineffective as an optimization mechanism, it was felt too loud for the
purpose of warning even to experienced users, and also resulted in
confusing people new to git.

This replaces the "empty" diffs with a single warning message at the
end. Having many such paths hurts performance, and you can run
"git-update-index --refresh" to update the lstat(2) information recorded
in the index in such a case. "git-status" does so as a side effect, and
that is more familiar to the end-user, so we recommend it to them.

The change affects only "git diff" that outputs patch text, because that
is where the annoyance of too many "empty" diff is most strongly felt,
and because the warning message can be safely ignored by downstream
tools without getting mistaken as part of the patch. For the low-level
"git diff-files" and "git diff-index", the traditional behaviour is
retained.

Unfortunately this is incorrect in the case where we hit the break

[PATCH] gitk: Handle MouseWheel events on Windows

Windows, unlike X-Windows, sends mousewheel events by default to the

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

Add support for an info version of the user manual

These patches use docbook2x in order to create an info version of the

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

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.

allow git-bundle to create bottomless bundle

While "git bundle" was a useful way to sneakernet incremental
changes, we did not allow:

$ git bundle create v2.6.20.bndl v2.6.20

to create a bundle that contains the whole history to a
well-known good revision. Such a bundle can be mirrored
everywhere, and people can prime their repository with it to
reduce the load on the repository that serves near the tip of
the development.

Optimize the two-way merge of git-read-tree tooLinus Torvalds Fri, 10 Aug 2007 19:31:20 +0000 (12:31 -0700)

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.

Optimize the common cases of git-read-treeLinus Torvalds Fri, 10 Aug 2007 19:21:20 +0000 (12:21 -0700)

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

so for large trees this is easily very noticeable indeed.

Fix "git commit directory/" performance anomaly

This trivial patch avoids re-hashing files that are already clean in the
index. This mirrors what commit 0781b8a9b2fe760fc4ed519a3a26e4b9bd6ccffe
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

(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).

Optimize "diff --cached" performance.Junio C Hamano Thu, 9 Aug 2007 20:42:50 +0000 (13:42 -0700)

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.

Start moving unpack-trees to "struct tree_desc"Linus Torvalds Fri, 10 Aug 2007 05:21:29 +0000 (22:21 -0700)

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.

Teach the update-paranoid to look at file differencesShawn O. Pearce Thu, 9 Aug 2007 06:38:12 +0000 (02:38 -0400)

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.

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".

It was very unfortunate that we added core.pager setting to the

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.

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.

Fix install-doc-quick target

The script starts in a subdirectory of the source directory to
muck with a branch whose structure does not have anything to
do with the actual work tree. Go up to the top to make it clear
that we operate on the whole tree.

It also exported GIT_DIR without any good reason. Remove it.

unpack-trees.c: assume submodules are clean during... Junio C Hamano Sat, 4 Aug 2007 05:13:09 +0000 (22:13 -0700)

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.

Document GIT_SSH environment variable alongside other variables

The GIT_SSH environment variable has survived for quite a while
without being documented, but has been mentioned on list and on
my day-job repositories can only be accessed via magic supplied
through the wonderous hack that is GIT_SSH.

Advertising it alongside other "low level magic" such as GIT_PAGER
and GIT_MERGE_VERBOSITY will certainly help others who need to
spread their own pixie dust to make things work.

gitweb: Fix handling of $file_name in feed generation

The commit b6093a5c, by Robert Fitzsimons:
"gitweb: Change atom, rss actions to use parse_commits."
forgot to pass $file_name parameter to parse_commits subroutine.

If git_feed is provided a file name, it ought to show only the history
affecting that file or a directory. The title was being set
correctly, but all commits from history were being shown.

gitweb: do not choke on recursive symlinkJunio C Hamano Fri, 27 Jul 2007 08:23:03 +0000 (01:23 -0700)

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.
