t7102: make the test fail if one of its check fails
Commit 952dfc6 tried to tighten the safety valves for doing
a "reset --hard" in a bare repository or outside the work
tree, but accidentally broke the case for GIT_WORK_TREE.
This patch unbreaks it.
Most git commands which need a work tree simply use
NEED_WORK_TREE in git.c to die before they get to their
cmd_* function. Reset, however, only needs a work tree in
some cases, and so must handle the work tree itself. The
error that 952dfc6 made was to simply forbid certain
operations if the work tree was not set up; instead, we need
to do the same thing that NEED_WORK_TREE does, which is to
call setup_work_tree(). We no longer have to worry about dying
in the non-worktree case, as setup_work_tree handles that
for us.

On big endian platforms with 8-byte unsigned long, the code reads the

order integer) incorrectly.
Input to "grep" is supposed to be "text", but we deliberately feed output
from "git diff --color" to sift it into two sets of lines (ones with
errors, the other without). Some implementations of "grep" only report
matches with the exit status, without showing the matched lines in their

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

worktree: don't segfault with an absolute pathspec without a work tree
ignore unknown color configuration
help.autocorrect: do not run a command if the command given is junk
Illustrate "filter" attribute with an example
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.
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.

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

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

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
old syntax.
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 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++').
