When determining the file mode from either ls-tree or diff-tree
output, we used to grab these octal mode string (typically 100644 or
100755) and then did
$git_perms .= "r" if ( $mode & 4 );
$git_perms .= "w" if ( $mode & 2 );
$git_perms .= "x" if ( $mode & 1 );
which was already wrong, as (100644 & 4) is very different from
oct("100644") & 4. An earlier refactoring 2c3af7e7 (cvsserver:
factor out git-log parsing logic, 2012-10-13) further changed it to
pick the third octal digit (10*0*644 or 10*0*755) from the left and
then do the above conversion, which does not make sense, either.
Let's use the third digit from the last of the octal mode string to
make sure we get the executable and read bits right.

git-svn: do not escape certain characters in paths
Subversion 1.7 and newer implement HTTPv2, an extension that should make HTTP
more efficient. Servers with support for this protocol will make the subversion
client library take an alternative code path that checks (with assertions)
whether the URL is "canonical" or not.
This patch fixes an issue I encountered while trying to `git svn dcommit` a
rename action for a file containing a single quote character ("User's Manual"
to "UserMan.tex"). It does not happen for older subversion 1.6 servers nor
non-HTTP(S) protocols such as the native svn protocol, only on an Apache server
shipping SVN 1.7. Trying to `git svn dcommit` under the aforementioned
conditions yields the following error which aborts the commit process:
Committing to http://example.com/svn ...
perl: subversion/libsvn_subr/dirent_uri.c:1520: uri_skip_ancestor:
Assertion `svn_uri_is_canonical(child_uri, ((void *)0))' failed.
error: git-svn died of signal 6
An analysis of the subversion source for the cause:
- The assertion originates from uri_skip_ancestor which calls
svn_uri_is_canonical, which fails when the URL contains percent-encoded values
that do not necessarily have to be encoded (not "canonical" enough). This is
done by a table lookup in libsvn_subr/path.c. Putting some debugging prints
revealed that the character ' is indeed encoded to %27 which is not
considered canonical.
- url_skip_ancestor is called by svn_ra_neon__get_baseline_info with the root
repository URL and path as parameters;
- which is called by copy_resource (libsvn_ra_neon/commit.c) for a copy action
(or in my case, renaming which is actually copy + delete old);
- which is called by commit_add_dir;
- which is assigned as a structure method "add_file" in
svn_ra_neon__get_commit_editor.
In the whole path, the path argument is not modified.
Through some more uninteresting wrapper functions, the Perl bindings gives you
access to the add_file method which will pass the path argument without
modifications to svn.
git-svn calls the "R"(ename) subroutine in Git::SVN::Editor which contains:
326 my $fbat = $self->add_file($self->repo_path($m->{file_b}), $pbat,
327 $self->url_path($m->{file_a}), $self->{r});
"repo_path" basically returns the path as-is, unless the "svn.pathnameencoding"
configuration property is set. "url_path" tries to escape some special
characters, but does not take all special characters into account, thereby
causing the path to contain some escaped characters which do not have to be
escaped.
The list of characters not to be escaped are taken from the
subversion/libsvn_subr/path.c file to fully account for all characters. Tested
with a filename containing all characters in the range 0x20 to 0x78 (inclusive).

When a single SVN repository is split into multiple Git repositories
many SVN revisions will exist in only one of the Git repositories
created. For some projects the only way to build a working artifact is
to check out corresponding versions of various repositories, with no
indication of what those are in the Git world - in the SVN world the
revision numbers are sufficient.
By adding "--before" to "git-svn find-rev" we can say "tell me what this
repository looked like when that other repository looked like this":
Subversion's canonical URLs are intended to make URL comparison easy
and therefore have strict rules about what characters are special
enough to urlencode and what characters should be left alone.
When in the fallback codepath because unable to use libsvn's own
canonicalization function for some reason, escape special characters
in URIs according to the svn_uri__char_validity[] table in
subversion/libsvn_subr/path.c (r935829). The libsvn versions that
trigger this code path are not likely to be strict enough to care, but
it's nicer to be consistent.
Noticed by using SVN 1.6.17 perl bindings, which do not provide
SVN::_Core::svn_uri_canonicalize (triggering the fallback code),
with libsvn 1.7.5, whose do_switch is fussy enough to care:

git p4: fail gracefully on sync with no master branch

For a clone or sync, --branch says where the newly imported

takes an argument, which is currently either something that
starts with "refs/", or if not, "refs/heads/p4" is prepended.

go in remotes/p4/ in most situations. Make that the new default,

Calling sync without a master branch dies with an error looking for

nothing due to branch detection code, but that is expected.

reset [--mixed]: use diff-based reset whether or not pathspec was given
Thanks to b65982b (Optimize "diff-index --cached" using cache-tree,

without paths. Some timings for the linux-2.6 repo to illustrate this
(best of five, warm cache):

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

reset.c: finish entire cmd_reset() whether or not pathspec is given
By not returning from inside the "if (pathspec)" block, we can let the

highlights the similarity between read_from_tree() and reset_index().
Signed-off-by: Martin von Zweigbergk <martinvonz@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
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

"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

reset: don't allow "git reset -- $pathspec" in bare repo
Running e.g. "git reset ." in a bare repo results in an index file
being created from the HEAD commit. The differences compared to the
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
D .mailmap
...

we branch off into read_from_tree() to reset with paths. Fix by moving

reset.c: pass pathspec around instead of (prefix, argv) pair
We use the path arguments in two places in reset.c: in

get_pathspec(), so we pass the (prefix, argv) pair to both
functions. Move the call to get_pathspec() out of these methods, for
two reasons: 1) One argument is simpler than two. 2) It lets us use
the (arguably clearer) "if (pathspec)" in place of "if (i < argc)".

"git reset $pathspec" currently exits with a non-zero exit code if the
worktree is dirty after resetting, which is inconsistent with reset
without pathspec, and it makes it harder to know whether the command
really failed. Change it to exit with code 0 regardless of whether the
worktree is dirty so that non-zero indicates an error.
This makes the 4 "disambiguation" test cases in t7102 clearer since
they all used to "fail", 3 of which "failed" due to changes in the
work tree. Now only the ambiguous one fails.

do_diff_cache() and we can remove the code for discarding and
re-reading it.
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).

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) {

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.

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.

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.

(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.
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.
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.
In the longer term, tightening rules is a good thing to do, and
because nobody who has worked in the remote helper area seems to be
interested in reviewing this, I would assume they do not think
such a retroactive tightening will affect their remote helpers. So
let's advance this topic to see what happens.

When user spells "cc:" in lowercase in the fake "header" in the
trailer part, send-email failed to pick up the addresses from
there. As e-mail headers field names are case insensitive, this
script should follow suit and treat "cc:" and "Cc:" the same way.
