With the previous fix 895c5ba3 (revision: do not peel tags used in
range notation, 2013-09-19), handle_revision_arg() that processes
command line arguments for the "git log" family of commands no
longer directly places the object pointed by the tag in the pending
object array when it sees a tag object. We used to place pointee
there after copying the flag bits like UNINTERESTING and
SYMMETRIC_LEFT.
This change meant that any flag that is relevant to later history
traversal must now be propagated to the pointed objects (most often
these are commits) while starting the traversal, which is partly
done by handle_commit() that is called from prepare_revision_walk().
We did propagate UNINTERESTING, but did not do so for others, most
notably SYMMETRIC_LEFT. This caused "git log --left-right v1.0..."
(where "v1.0" is a tag) to start losing the "leftness" from the
commit the tag points at.

"git rev-list --objects ^A^{tree} B^{tree}" ought to mean "I want a
list of objects inside B's tree, but please exclude the objects that
appear inside A's tree".
we see the top-level tree marked as uninteresting (i.e. ^A^{tree} in
the above example) and call mark_tree_uninteresting() on it; this
unfortunately prevents us from recursing into the tree and marking
the objects in the tree as uninteresting.
The reason why "git log ^A A" yields an empty set of commits,
i.e. we do not have a similar issue for commits, is because we call
mark_parents_uninteresting() after seeing an uninteresting commit.
The uninteresting-ness of the commit itself does not prevent its
parents from being marked as uninteresting.
Introduce mark_tree_contents_uninteresting() and structure the code
in handle_commit() in such a way that it makes it the responsibility
of the callchain leading to this function to mark commits, trees and
blobs as uninteresting, and also make it the responsibility of the
helpers called from this function to mark objects that are reachable
from them.
Note that this is a very old bug that probably dates back to the day
when "rev-list --objects" was introduced. The line to clear
tree->object.parsed at the end of mark_tree_contents_uninteresting()
can be removed when this fix is merged to the codebase after
6e454b9a (clear parsed flag when we free tree buffers, 2013-06-05).

A range notation "A..B" means exactly the same thing as what "^A B"
means, i.e. the set of commits that are reachable from B but not
from A. But the internal representation after the revision parser
parsed these two notations are subtly different.
- "rev-list ^A B" leaves A and B in the revs->pending.objects[]
array, with the former marked as UNINTERESTING and the revision
traversal machinery propagates the mark to underlying commit
objects A^0 and B^0.
- "rev-list A..B" peels tags and leaves A^0 (marked as
UNINTERESTING) and B^0 in revs->pending.objects[] array before
the traversal machinery kicks in.
This difference usually does not matter, but starts to matter when
the --objects option is used. For example, we see this:
$ git rev-list --objects v1.8.4^1..v1.8.4 | grep $(git rev-parse v1.8.4)
$ git rev-list --objects v1.8.4 ^v1.8.4^1 | grep $(git rev-parse v1.8.4)
04f013dc38 v1.8.4
With the former invocation, the revision traversal machinery never
hears about the tag v1.8.4 (it only sees the result of peeling it,
i.e. the commit v1.8.4^0), and the tag itself does not appear in the
output. The latter does send the tag object itself to the output.
Make the range notation keep the unpeeled objects and feed them to
the traversal machinery to fix this inconsistency.

The diffstat generation logic, with --stat-count limit, is
implemented as three loops.
- The first counts the width necessary to show stats up to
specified number of entries, and notes up to how many entries in
the data we need to iterate to show the graph;
- The second iterates that many times to draw the graph, adjusts
the number of "total modified files", and counts the total
added/deleted lines for the part that was shown in the graph;
- The third iterates over the remainder and only does the part to
count "total added/deleted lines" and to adjust "total modified
files" without drawing anything.
Move the logic to count added/deleted lines and modified files from
the second loop to the third loop.
This incidentally fixes a bug. The third loop was not filtering
binary changes (counted in bytes) from the total added/deleted as it
should. The second loop implemented this correctly, so if a binary
change appeared earlier than the --stat-count cutoff, the code
counted number of added/deleted lines correctly, but if it appeared
beyond the cutoff, the number of lines would have mixed with the
byte count in the buggy third loop.

We currently just look at raw blob data when using "-S" to
pickaxe. This is mostly historical, as pickaxe predates the
textconv feature. If the user has bothered to define a
textconv filter, it is more likely that their search string will be
on the textconv output, as that is what they will see in the
diff (and we do not even provide a mechanism for them to
search for binary needles that contain NUL characters).
This patch teaches "-S" to use textconv, just as we
already do for "-G".
Signed-off-by: Jeff King <peff@peff.net>
If you use "-G" to grep a diff, we will apply a configured
textconv filter to the data before generating the diff.
However, if the diff is an addition or deletion, we do not
bother running the diff at all, and just look for the token
in the added (or removed) content. This works because we
know that the diff must contain every line of content.
However, while we used the textconv-derived buffers in the
regular diff, we accidentally passed the original unmodified
buffers to regexec when checking the added or removed
content. This could lead to an incorrect answer.
Worse, in some cases we might have a textconv buffer but no
original buffer (e.g., if we pulled the textconv data from
cache, or if we reused a working tree file when generating
it). In that case, we could actually feed NULL to regexec
and segfault.

Before a branch is deleted, we check that it points to a valid
commit. With -d we also check that the commit is a merged; this
check is not done with -D.
The reason for that is that commits pointed to by branches should
never go missing; if they do then something broke and it's better
to stop instead of adding to the mess. And a non-merged commit
may contain changes that are worth preserving, so we require the
stronger option -D instead of -d to get rid of them.
If a branch consists of a symref, these concerns don't apply.
Deleting such a branch can't make a commit become unreferenced,
so we don't need to check if it is merged, or even if it is
actually a valid commit. Skip them in that case. This allows
us to delete dangling symref branches.

git-format-patch does currently not parse user supplied extra header
values (e. g., --cc, --add-header) and just replays them. That forces
users to add them RFC 2822/2047 conform in encoded form, e.g.
--cc '=?UTF-8?q?Jan=20H=2E=20Sch=C3=B6nherr?= <...>'
which is inconvenient. We would want to update git-format-patch to
accept human-readable input
--cc 'Jan H. Schönherr <...>'
and handle the encoding, wrapping and quoting internally in the future,
similar to what is already done in git-send-email. The necessary code
should mostly exist in the code paths that handle the From: and Subject:
headers.
Whether we want to do this only for the git-format-patch options
--to and --cc (and the corresponding config options) or also for
user supplied headers via --add-header, is open for discussion.
For now, add test_expect_failure tests for To: and Cc: headers as a

character too early.

"%w(11,1,2)" (wrap at 11 characters, 1 char indent of first line, 2 char
indent of following lines) results in four lines: " This is", " the",
" sixth", " commit." This is wrong, because " the sixth" is exactly
11 characters long, and thus allowed.

The behavior of "git diff --stat" is rather odd for files that have
zero lines of changes: it will discount them entirely unless they were
renames.
Which means that the stat output will simply not show files that only
had "other" changes: they were created or deleted, or their mode was
changed.
Now, those changes do show up in the summary, but so do renames, so
the diffstat logic is inconsistent. Why does it show renames with zero
lines changed, but not mode changes or added files with zero lines
changed?
So change the logic to not check for "is_renamed", but for
"is_interesting" instead, where "interesting" is judged to be any
action but a pure data change (because a pure data change with zero
data changed really isn't worth showing, if we ever get one in our
diffpairs).
So if you did
chmod +x Makefile
git diff --stat
before, it would show empty (" 0 files changed"), with this it shows
Makefile | 0
1 file changed, 0 insertions(+), 0 deletions(-)
which I think is a more correct diffstat (and then with "--summary" it
shows *what* the metadata change to Makefile was - this is completely
consistent with our handling of renamed files).
Side note: the old behavior was *really* odd. With no changes at all,
"git diff --stat" output was empty. With just a chmod, it said "0
files changed". No way is our legacy behavior sane.

This test script uses "svn cp" to create a branch with an @-sign in
its name:
svn cp "pr ject/trunk" "pr ject/branches/not-a@{0}reflog"
That sets up for later tests that fetch the branch and check that git
svn mangles the refname appropriately.
Unfortunately, modern svn versions interpret path arguments with an
@-sign as an example of path@revision syntax (which pegs a path to a
particular revision) and truncate the path or error out with message
"svn: E205000: Syntax error parsing peg revision '{0}reflog'".
When using subversion 1.6.x, escaping the @ sign as %40 avoids trouble
(see 08fd28bb, 2010-07-08). Newer versions are stricter:
$ svn cp "$repo/pr ject/trunk" "$repo/pr ject/branches/not-a%40{reflog}"
svn: E205000: Syntax error parsing peg revision '%7B0%7Dreflog'
The recommended method for escaping a literal @ sign in a path passed
to subversion is to add an empty peg revision at the end of the path
("branches/not-a@{0}reflog@"). Do that.
Pre-1.6.12 versions of Subversion probably treat the trailing @ as
another literal @-sign (svn issue 3651). Luckily ever since
v1.8.0-rc0~155^2~7 (t9118: workaround inconsistency between SVN
versions, 2012-07-28) the test can survive that.
