remote-hg: fix handling of file perms when pushing

Previously, when changing and committing an executable file, the file
would loose its executable bit on the hg side. Likewise, symlinks ended
up as "normal" files". This was not immediately apparent on the git side

reset [--mixed]: use diff-based reset whether or not pathspec was given

Thanks to b65982b (Optimize "diff-index --cached" using cache-tree,
2009-05-20), resetting with paths is much faster than resetting
without paths. Some timings for the linux-2.6 repo to illustrate this
(best of five, warm cache):

reset reset .
real 0m0.219s 0m0.080s
user 0m0.140s 0m0.040s
sys 0m0.070s 0m0.030s

These two commands should do the same thing, so instead of having the
user type the trailing " ." to get the faster do_diff_cache()-based
implementation, always use it when doing a mixed reset, with or
without paths (so "git reset $rev" would also be faster).

Timing "git reset" shows that it indeed becomes as fast as
"git reset ." after this patch.

Some users seem to think, knowingly or not, that being on an unborn
branch is like having a commit with an empty tree checked out, but
when run on an unborn branch, "git reset" currently fails with:

fatal: Failed to resolve 'HEAD' as a valid ref.

Instead of making users figure out that they should run

git rm --cached -r .

, let's teach "git reset" without a revision argument, when on an
unborn branch, to behave as if the user asked to reset to an empty
tree. Don't take the analogy with an empty commit too far, though, but
still disallow explictly referring to HEAD in "git reset HEAD".

Resetting with paths does not update HEAD and there is nothing else
that a commit should be needed for. Relax the argument parsing so only
a tree is required.

The sha1 is only passed to read_from_tree(), which already only
requires a tree.

The "rev" variable we pass to run_add_interactive() will resolve to a
tree. This is fine since interactive_reset only needs the parameter to
be a treeish and doesn't use it for display purposes.

reset [--mixed]: only write index file once

When doing a mixed reset without paths, the index is locked, read,
reset, and written back as part of the actual reset operation (in
reset_index()). Then, when showing the list of worktree modifications,
we lock the index again, refresh it, and write it.

Change this so we only write the index once, making "git reset" a
little faster. It does mean that the index lock will be held a little
longer, but the difference is small compared to the time spent
refreshing the index.

There is one minor functional difference: We used to say "Could not
write new index file." if the first write failed, and "Could not
refresh index" if the second write failed. Now, we will only use the
first message.

This speeds up "git reset" a little on the linux-2.6 repo (best of

reset --keep: only write index file once

"git reset --keep" calls reset_index_file() twice, first doing a
two-way merge to the target revision, updating the index and worktree,
and then resetting the index. After each call, we write the index
file.

In the unlikely event that the second call to reset_index_file()
fails, the index will have been merged to the target revision, but
HEAD will not be updated, leaving the user with a dirty index.

By moving the locking, writing and committing out of
reset_index_file() and into the caller, we can avoid writing the index
twice, thereby making the sure we don't end up in the half-way reset
state. As a bonus, we speed up "git reset --keep" a little on the

Running e.g. "git reset ." in a bare repo results in an index file

index are then printed as usual, but since there is no worktree, it
will appear as if all files are deleted. For example, in a bare clone
of git.git:

Unstaged changes after reset:
D .gitattributes
D .gitignore

There are two paths to update_index_refresh() from cmd_reset(), but on
both paths, either read_cache() or read_cache_unmerged() will have
been called, so the call to read_cache() in this method is redundant
(although practically free).

attr: fix off-by-one directory component length calculation

94bc671 (Add directory pattern matching to attributes - 2012-12-08)
uses find_basename() to calculate the length of directory part in
prepare_attr_stack. This function expects the directory without the
trailing slash (as "origin" field in match_attr struct is without the
trailing slash). find_basename() includes the trailing slash and
confuses push/pop algorithm.

Consider path = "abc/def" and the push down code:

while (1) {
len = strlen(attr_stack->origin);
if (dirlen <= len)
break;
cp = memchr(path + len + 1, '/', dirlen - len - 1);
if (!cp)
cp = path + dirlen;

dirlen is 4, not 3, without this patch. So when attr_stack->origin is
"abc", it'll miss the exit condition because 4 <= 3 is wrong. It'll
then try to push "abc/" down the attr stack (because "cp" would be
NULL). So we have both "abc" and "abc/" in the stack.

Next time when "abc/ghi" is checked, "abc/" is popped out because of
the off-by-one dirlen, only to be pushed back in again by the above
code. This repeats for all files in the same directory. Which means
at least one failed open syscall per file, or more if .gitattributes
exists.

This is the perf result with 10 runs on git.git:

pretty: use prefixcmp instead of memcmp on NUL-terminated strings

This conversion avoids the need for magic string length numbers in the
code. And unlike memcmp(), prefixcmp() is careful to not run over the
end of a string.

hooks: Add function to check if a hook existsAaron Schrab Sun, 13 Jan 2013 05:17:02 +0000 (00:17 -0500)

hooks: Add function to check if a hook exists

Create find_hook() function to determine if a given hook exists and is
executable. If it is, the path to the script will be returned,
otherwise NULL is returned.

This encapsulates the tests that are used to check for the existence of
a hook in one place, making it easier to modify those checks if that is
found to be necessary. This also makes it simple for places that can
use a hook to check if a hook exists before doing, possibly lengthy,
setup work which would be pointless if no such hook is present.

The returned value is left as a static value from get_pathname() rather
than a duplicate because it is anticipated that the return value will
either be used as a boolean, immediately added to an argv_array list
which would result in it being duplicated at that point, or used to
actually run the command without much intervening work. Callers which
need to hold onto the returned value for a longer time are expected to
duplicate the return value themselves.

rebase --preserve-merges: keep all merge commits including empty ones

Since 90e1818f9a (git-rebase: add keep_empty flag, 2012-04-20)
'git rebase --preserve-merges' fails to preserve empty merge commits
unless --keep-empty is also specified. Merge commits should be
preserved in order to preserve the structure of the rebased graph,
even if the merge commit does not introduce changes to the parent.

Teach rebase not to drop merge commits only because they are empty.

A special case which is not handled by this change is for a merge commit
whose parents are now the same commit because all the previous different
parents have been dropped as a result of this rebase or some previous
operation.

git-clean: Display more accurate delete messagesZoltan Klinger Thu, 10 Jan 2013 22:53:46 +0000 (09:53 +1100)

git-clean: Display more accurate delete messages

(1) Only print out the names of the files and directories that got
actually deleted. Also do not mention that we are not removing
directories when the user did not ask us to do so with '-d'.
(2) Show ignore message for skipped untracked git repositories.

Consider the following repo layout:

test.git/
|-- tracked_dir/
| |-- some_tracked_file
| |-- some_untracked_file
|-- tracked_file
|-- untracked_file
|-- untracked_foo/
| |-- bar/
| | |-- bar.txt
| |-- emptydir/
| |-- frotz.git/
| |-- frotz.tx
|-- untracked_some.git/
|-- some.txt

Suppose the user issues 'git clean -fd' from the test.git directory.

When -d option is used and untracked directory 'foo' contains a
subdirectory 'frotz.git' that is managed by a different git repository
therefore it will not be removed.

$ git clean -fd
Removing tracked_dir/some_untracked_file
Removing untracked_file
Removing untracked_foo/
Removing untracked_some.git/

The message displayed to the user is slightly misleading. The foo/
directory has not been removed because of foo/frotz.git still exists.
On the other hand the subdirectories 'bar' and 'emptydir' have been
deleted but they're not mentioned anywhere. Also, untracked_some.git
has not been removed either.

This behaviour is the result of the way the deletion of untracked
directories are reported. In the current implementation they are
deleted recursively but only the name of the top most directory is
printed out. The calling function does not know about any
subdirectories that could not be removed during the recursion.

Improve the way the deleted directories are reported back to
the user:
(1) Create a recursive delete function 'remove_dirs' in builtin/clean.c
to run in both dry_run and delete modes with the delete logic as
follows:
(a) Check if the current directory to be deleted is an untracked
git repository. If it is and --force --force option is not set
do not touch this directory, print ignore message, set dir_gone
flag to false for the caller and return.
(b) Otherwise for each item in current directory:
(i) If current directory cannot be accessed, print warning,
set dir_gone flag to false and return.
(ii) If the item is a subdirectory recurse into it,
check for the returned value of the dir_gone flag.
If the subdirectory is gone, add the name of the deleted
directory to a list of successfully removed items 'dels'.
Else set the dir_gone flag as the current directory
cannot be removed because we have at least one subdirectory
hanging around.
(iii) If it is a file try to remove it. If success add the
file name to the 'dels' list, else print error and set
dir_gone flag to false.
(c) After we finished deleting all items in the current directory and
the dir_gone flag is still true, remove the directory itself.
If failed set the dir_gone flag to false.

(d) If the current directory cannot be deleted because the dir_gone flag
has been set to false, print out all the successfully deleted items
for this directory from the 'dels' list.
(e) We're done with the current directory, return.

(2) Modify the cmd_clean() function to:
(a) call the recursive delete function 'remove_dirs()' for each
topmost directory it wants to remove
(b) check for the returned value of dir_gone flag. If it's true
print the name of the directory as being removed.

Consider the output of the improved version:

$ git clean -fd
Removing tracked_dir/some_untracked_file
Removing untracked_file
Skipping repository untracked_foo/frotz.git
Removing untracked_foo/bar
Removing untracked_foo/emptydir
Skipping repository untracked_some.git/

Now it displays only the file and directory names that got actually
deleted and shows the name of the untracked git repositories it ignored.

The --separate-git-dir option was introduced to make it simple to put
the git directory somewhere outside the worktree, for example when
cloning a repository for use as a submodule.

It was not intended for use when creating a bare repository. In that
case there is no worktree and it is more natural to directly clone the
repository and create a .git file as separate steps:

git clone --bare /path/to/repo.git bar.git
printf 'gitdir: bar.git\n' >foo.git

Forbid the combination, making the command easier to explain.

contrib/vim: simplify instructions for old vim support

Rely on the upstream filetype.vim instead of duplicating its rules in
git's instructions for syntax highlighting support on pre-7.2 vim
versions.

The result is a shorter contrib/vim/README. More importantly, it lets
us punt on maintenance of the autocmd rules.

So now when we fix the upstream gitsendemail rule in light of commit
eed6ca7, new git users stuck on old vim reading contrib/vim/README can
automagically get the fix without any further changes needed to git.

Once the world has moved on to vim 7.2+ completely, we can get rid of
these instructions, but for now if they are this simple it's
effortless to keep them.

t0008: avoid brace expansion

Brace expansion is a shell feature that's not required by POSIX and not
supported by dash nor NetBSD's sh. Explicitly list all combinations
instead. Also avoid calling touch by creating the test files with a
redirection instead, as suggested by Junio.

Makefile: detect when PYTHON_PATH changes

When make is run, the python scripts are created from *.py files that
are changed to use the python given by PYTHON_PATH. And PYTHON_PATH
is set by default to /usr/bin/python on Linux.

However, next time make is run with a different value in PYTHON_PATH,
we failed to regenerate these scripts.
