status: don't require the repository to be writable

We need to update the index before hooks run when actually making a
commit, but we shouldn't have to write the index when running "status".
If we can, then we have already spent cycles to refresh the index and
it is a waste not to write it out, but it is not a disaster if we cannot
write it out. The main reason the user is running "git status" is to get
the "status", and refreshing the index is a mere side effect that we can
do without.

grep: -L should show empty files

The -L (--files-without-match) option is supposed to show paths that
produced no matches. When running the internal grep on work tree files,
however, we had an optimization to just return on zero-sized files,
without doing anything.

This optimization doesn't matter too much in practice (a tracked empty
file must be rare, or there is something wrong with your project); to
produce results consistent with GNU grep, we should stop the optimization
and show empty files as not having the given pattern.

Input to "grep" is supposed to be "text", but we deliberately feed output

errors, the other without). Some implementations of "grep" only report
matches with the exit status, without showing the matched lines in their
output (e.g. OpenBSD 4.6, which says "Binary file .. matches").

Fortunately, "grep -a" is often a way to force the command to treat its

The old function was incorrect; in some instances it marks a cherry picked
range as a merged branch (because of an incorrect assumption that
'rev-list COMMIT --not RANGE' would work). This is replaced with a

of dealing with branches with many cherry picks to one 'merge-base' call

git-svn: exclude already merged tips using one rev-list call

The old function would have to check all mentioned merge tips, every time
that the mergeinfo ticket changed. This involved 1-2 rev-list operation
for each listed mergeinfo line. If there are a lot of feature branches
being merged into a trunk, this makes for a very expensive operation for
detecting the new parents on every merge.

This new version first uses a single 'rev-list' to figure out which commit
ranges are already reachable from the parents. This is used to eliminate
the already merged branches from the list.

git svn: fix --revision when fetching deleted pathsEric Wong Mon, 21 Dec 2009 10:06:04 +0000 (02:06 -0800)

git svn: fix --revision when fetching deleted paths

When using the -r/--revision argument to fetch deleted history,
calling SVN::Ra::get_log() from an SVN::Ra object initialized
to track the deleted URL will fail.

This regression was introduced in:
commit 4aacaeb3dc82bb6479e70e120053dc27a399460e
"fix shallow clone when upstream revision is too new"

We now ignore errors from SVN::Ra::get_log() here because using
--revision will always override the value of $head here if
(and only if) we're tracking deleted directories.

rebase -i: abort cleanly if the editor fails to launch

If the user's configured editor is emacsclient, the editor
will fail to launch if emacs is not running and the git
command that tried to lanuch the editor will abort. For most
commands, all you have to do is to start emacs and repeat
the command.

The "git rebase -i" command, however, aborts without cleaning
the "$GIT_DIR/rebase-merge" directory if it fails to launch the
editor, so you'll need to do "git rebase --abort" before
repeating the rebase command.

Change "git rebase -i" to terminate using "die_abort" (instead of
with "die") if the initial launch of the editor fails.

worktree: don't segfault with an absolute pathspec without a work tree

If a command is run with an absolute path as a pathspec inside a bare
repository, e.g. "rev-list HEAD -- /home", the code tried to run strlen()
on NULL, which is the result of get_git_work_tree(), and segfaulted. It
should just fail instead.

Currently the function returns NULL even inside .git/ in a repository
with a work tree, but that is a separate issue.

ignore unknown color configurationJeff King Sat, 12 Dec 2009 12:25:24 +0000 (07:25 -0500)

ignore unknown color configuration

When parsing the config file, if there is a value that is
syntactically correct but unused, we generally ignore it.
This lets non-core porcelains store arbitrary information in
the config file, and it means that configuration files can
be shared between new and old versions of git (the old
versions might simply ignore certain configuration).

The one exception to this is color configuration; if we
encounter a color.{diff,branch,status}.$slot variable, we
die if it is not one of the recognized slots (presumably as
a safety valve for user misconfiguration). This behavior
has existed since 801235c (diff --color: use
$GIT_DIR/config, 2006-06-24), but hasn't yet caused a
problem. No porcelain has wanted to store extra colors, and
we once a color area (like color.diff) has been introduced,
we've never changed the set of color slots.

However, that changed recently with the addition of
color.diff.func. Now a user with color.diff.func in their
config can no longer freely switch between v1.6.6 and older
versions; the old versions will complain about the existence
of the variable.

This patch loosens the check to match the rest of
git-config; unknown color slots are simply ignored. This
doesn't fix this particular problem, as the older version
(without this patch) is the problem, but it at least
prevents it from happening again in the future.

help.autocorrect: do not run a command if the command given is junk

If a given command is not found, then help.c tries to guess which one the

non-zero (i.e., a delay after which the command is run automatically), the
latter restriction on dissimilarity was not obeyed.

In my case, this happened:

$ git ..daab02

Fix archive format with -- on the command line

Giving --format from the command line, or using output file extention to
DWIM the output format, with a pathspec that is disambiguated with an
explicit double-dash on the command line, e.g.

git archive -o file --format=zip HEAD -- path
git archive -o file.zip HEAD -- path

didn't work correctly.

This was because the code reordered (when one was given) or added (when
the format was inferred) a --format argument at the end, effectively
making it to "archive HEAD -- path --format=zip", i.e. an extra pathspec
that is unlikely to match anything.

The command line argument list should always be "options, revs and then
paths", and we should set a good example by inserting the --format at the
beginning instead.

They caused a "git pull" (without any arguments, and without any local
commits---only to update to the other side) to warn that commit log
message is ignored because the merge resulted in a fast-forward.

Another possible solution is to add an extra option to "git merge" so that
"git pull" can tell it that the message given is not coming from the end
user (the canned message is passed just in case the merge resulted in a
non-ff and caused commit), but I think it is easier _not_ to deprecate the

add-interactive: fix deletion of non-empty files

Commit 24ab81a fixed the deletion of empty files, but broke
deletion of non-empty files. The approach it took was to
factor out the "deleted" line from the patch header into its
own hunk, the same way we do for mode changes. However,
unlike mode changes, we only showed the special "delete this
file" hunk if there were no other hunks. Otherwise, the user
would annoyingly be presented with _two_ hunks: one for
deleting the file and one for deleting the content.

This meant that in the non-empty case, we forgot about the
deleted line entirely, and we submitted a bogus patch to
git-apply (with "/dev/null" as the destination file, but not
marked as a deletion).

Instead, this patch combines the file deletion hunk and the
content deletion hunk (if there is one) into a single
deletion hunk which is either staged or not.

git-gui: Increase blame viewer usability on MacOS.

On MacOS raising a window causes the focus to be transferred
to it -- although it may actually be a bug in the Tcl/Tk port.
When this happens with the blame viewer tooltips, it makes
the interface less usable, because Entry and Leave handlers
on the text view cause the tip to disappear once the mouse
is moved even 1 pixel.

This commit makes the code raise the main window on MacOS
when Tk 8.5 is used. This version seems to properly support
wm transient by making the tip stay on top of the master,
so reraising the master does not cause it to disappear. Thus
the only remaining sign of problems is slight UI flicker
when focus is momentarily transferred to the tip and back.

git-gui: search 4 directories to improve statistic of gc hint

On Windows, git-gui suggests running the garbage collector if it finds
1 or more files in .git/objects/42 (as opposed to 8 files on other
platforms). The probability of that happening if the repo contains
about 100 loose objects is 32%. The probability for the same to happen
when searching 4 directories is only 8%, which is bit more reasonable.

Also remove $objects_limit from the message, because we already know
that we are above (or close to) that limit. Telling the user about
that number does not really give him any useful information.

The following octave script shows the probability for at least m*q
objects to be found in q subdirectories of .git/objects if n is the
total number of objects.

q = 4;
m = [1 2 8];
n = 0:10:2000;

P = zeros(length(n), length(m));
for k = 1:length(n)
P(k, :) = 1-binocdf(q*m-1, n(k), q/(256-q));
end
plot(n, P);

Fix diff -B/--dirstat miscounting of newly added contentsLinus Torvalds Fri, 4 Dec 2009 20:07:47 +0000 (12:07 -0800)

Fix diff -B/--dirstat miscounting of newly added contents

What used to happen is that diffcore_count_changes() simply ignored any
hashes in the destination that didn't match hashes in the source. EXCEPT
if the source hash didn't exist at all, in which case it would count _one_
destination hash that happened to have the "next" hash value. As a
consequence, newly added material was often undercounted, making output
from --dirstat and "complete rewrite" detection used by -B unrelialble.

This changes it so that:

- whenever it bypasses a destination hash (because it doesn't match a
source), it counts the bytes associated with that as "literal added"

- at the end (once we have used up all the source hashes), we do the same
thing with the remaining destination hashes.

- when hashes do match, and we use the difference in counts as a value,
we also use up that destination hash entry (the 'd++').

reset: improve worktree safety valvesJeff King Fri, 4 Dec 2009 11:11:58 +0000 (06:11 -0500)

reset: improve worktree safety valves

The existing code checked to make sure we were not in a bare
repository when doing a hard reset. However, we should take
this one step further, and make sure we are in a worktree.
Otherwise, we can end up munging files inside of '.git'.

Furthermore, we should do the same check for --merge resets,
which have the same properties. Actually, a merge reset of
HEAD^ would already complain, since further down in the code
we want a worktree. However, it is nicer to check up-front;
then we are sure we cover all cases ("git reset --merge"
would run, even though it wasn't doing anything) and we can
give a more specific message.

Add tests to t7103 to cover these cases and some missing ones.
