The command line parser choked "git cherry-pick $name" when $name can be
both revision name and a pathname, even though $name can never be a path
in the context of the command.
The issue the patch addresses is real, but the way it is implemented felt
unnecessarily invasive a bit. It may be cleaner for this caller to add
the "--" to the end of the argv_array it passes to setup_revisions().

If a commit-ish passed to cherry-pick or revert happens to have a file
of the same name, git complains that the argument is ambiguous and
advises to use '--'. To make things worse, the '--' argument is removed
by parse_options, und so passing '--' has no effect.
Instead, always interpret cherry-pick/revert arguments as revisions.

Previously it was not possible to iterate revisions twice using the
revision walking api. We add a reset_revision_walk() which clears the
used flags. This allows us to do multiple sequencial revision walks.
We add the appropriate calls to the existing submodule machinery doing
revision walks. This is done to avoid surprises if future code wants to
call these functions more than once during the processes lifetime.

This teaches the "log" family of commands to pass the GPG signature in the
commit objects to "gpg --verify" via the verify_signed_buffer() interface
used to verify signed tag objects. E.g.
$ git show --show-signature -s HEAD
shows GPG output in the header part of the output.

The new flag leak_pending in struct rev_info can be used to prevent
prepare_revision_walk from freeing the list of pending objects. It
will still forget about them, so it really is leaked. This behaviour
may look weird at first, but it can be useful if the pointer to the
list is saved before calling prepare_revision_walk.

Often we want to verify everything reachable from a given set of commits
are present in our repository and connected without a gap to the tips of
our refs. We used to do this for this purpose:
$ rev-list --objects $commits_to_be_tested --not --all
Even though this is good enough for catching missing commits and trees,
we show the object name but do not verify their existence, let alone their
well-formedness, for the blob objects at the leaf level.
Add a new "--verify-object" option so that we can catch missing and broken
blobs as well.

Given a complex set of revision specifiers on the command line, it is too
late to look at the flags of the objects in the initial traversal list at
the beginning of limit_list() in order to determine what the objects the
end-user explicitly listed on the command line were. The process to move
objects from the pending array to the traversal list may have marked
objects that are not mentioned as UNINTERESTING, when handle_commit()
marked the parents of UNINTERESTING commits mentioned on the command line
by calling mark_parents_uninteresting().
This made "rev-list --ancestry-path ^A ..." to mistakenly list commits
that are descendants of A's parents but that are not descendants of A
itself, as ^A from the command line causes A and its parents marked as
UNINTERESTING before coming to limit_list(), and we try to enumerate the
commits that are descendants of these commits that are UNINTERESTING
before we start walking the history.
It actually is too late even if we inspected the pending object array
before calling prepare_revision_walk(), as some of the same objects might
have been mentioned twice, once as positive and another time as negative.
The "rev-list --some-option A --not --all" command may want to notice,
even if the resulting set is empty, that the user showed some interest in
"A" and do something special about it.
Prepare a separate array to keep track of what syntactic element was used
to cause each object to appear in the pending array from the command line,
and populate it as setup_revisions() parses the command line.

In older versions of git, we used rfc822 header folding to
indicate that the original subject line had multiple lines
in it. But since a1f6baa (format-patch: wrap long header
lines, 2011-02-23), we now use header folding whenever there
is a long line.
This means that "git am" cannot trust header folding as a
sign from format-patch that newlines should be preserved.
Instead, format-patch needs to signal more explicitly that
the newlines are significant. This patch does so by
rfc2047-encoding the newlines in the subject line. No
changes are needed on the "git am" end; it already decodes
the newlines properly.

Introduce --min-parents and --max-parents options which limit the
revisions to those commits which have at least (or at most) that many
commits, where negative arguments for --max-parents= denote infinity
(i.e. no upper limit).
In particular:
--max-parents=1 is the same as --no-merges;
--min-parents=2 is the same as --merges;
--max-parents=0 shows only roots; and
--min-parents=3 shows only octopus merges
Using --min-parents=n and --max-parents=m with n>m gives you what you ask
for (i.e. nothing) for obvious reasons, just like when you give --merges
(show only merge commits) and --no-merges (show only non-merge commits) at
the same time.
Also, introduce --no-min-parents and --no-max-parents to do the obvious
thing for convenience.
We compute the number of parents only when we limit by that, so there
is no performance impact when there are no limiters.

Currently, commit marks (left, right, boundary, cherry) are output right
before the commit sha1, which makes it difficult to copy sha1s. Sample
output for "git log --oneline --cherry":
=049c269 t6007: test rev-list --cherry
Change this to
= 049c269 t6007: test rev-list --cherry
which matches exactly the current output of "git log --graph".
Leave "git rev-list" output as is (no space) so that they do not break.

The existing "--cherry-pick" does not work with unsymmetric ranges
(A..B) for obvious reasons.
Introduce "--left-only" and "--right-only" which limit the output to
commits on the respective sides of a symmetric range (i.e. only "<"
resp. ">" commits as per "--left-right").
This is especially useful for things like
git log --cherry-pick --right-only @{u}...
which is much more flexible (and descriptive) than
git cherry @{u} | sed -ne 's/^+ //p'
and potentially more useful than
git log --cherry-pick @{u}...

Add a --count option that, instead of actually listing the commits,
merely counts them.
This is mostly geared towards script use, and to this end it acts
specially when used with --left-right: it outputs the left and right
counts separately. Previously, scripts would have to run a shell loop
or small inline script over to achieve the same. (Without
--left-right, a simple |wc -l does the job.)

"rev-list A..H" computes the set of commits that are ancestors of H, but
excludes the ones that are ancestors of A. This is useful to see what
happened to the history leading to H since A, in the sense that "what does
H have that did not exist in A" (e.g. when you have a choice to update to
H from A).
x---x---A---B---C <-- topic
/ \
x---x---x---o---o---o---o---M---D---E---F---G <-- dev
/ \
x---o---o---o---o---o---o---o---o---o---o---o---N---H <-- master
The result in the above example would be the commits marked with caps
letters (except for A itself, of course), and the ones marked with 'o'.
When you want to find out what commits in H are contaminated with the bug
introduced by A and need fixing, however, you might want to view only the
subset of "A..B" that are actually descendants of A, i.e. excluding the
ones marked with 'o'. Introduce a new option --ancestry-path to compute
this set with "rev-list --ancestry-path A..B".
Note that in practice, you would build a fix immediately on top of A and
"git branch --contains A" will give the names of branches that you would
need to merge the fix into (i.e. topic, dev and master), so this may not
be worth paying the extra cost of postprocessing.

Traditionally, "show" defaulted to "show --cc" (dense combined patch), but
asking for combined patch with "show -c" didn't turn the patch output
format on; the placement of this logic in setup_revisions() dates back to
cd2bdc5 (Common option parsing for "git log --diff" and friends,
2006-04-14).
This unfortunately cannot be done as a trivial change of "if dense
combined is asked, default to patch format" done in setup_revisions() to
"if any combined is asked, default to patch format", as "diff-tree -c"
needs to default to raw, while "diff-tree --cc" needs to default to patch,
and they share the codepath. These command specific defaults are now
handled in the new "tweak" callback that can be customized by individual
command implementations.

So far the last parameter to setup_revisions() was to specify the default
ref when the command line did not give any (typically "HEAD"). This changes
it to take a pointer to a structure so that we can add other information without
touching too many codepaths in later patches.
There is no functionality change.

Giving "Notes" information in the default output format of "log" and
"show" is a sensible progress (the user has asked for it by having the
notes), but for some commands (e.g. "format-patch") spewing notes into the
formatted commit log message without being asked is too aggressive.
Enable notes output only for "log", "show", "whatchanged" by default and
only when the user didn't ask any specific --pretty/--format from the
command line; users can explicitly override this default with --show-notes
and --no-notes option.
Parts of tests are taken from Jeff King's fix.

Move the logic to read revs from standard input that rev-list knows about
from it to revision machinery, so that all the users of setup_revisions()
can feed the list of revs from the standard input when "--stdin" is used
on the command line.
Allow some users of the revision machinery that want different semantics
from the "--stdin" option to disable it by setting an option in the
rev_info structure.
This also cleans up the kludge made to bundle.c via cut and paste.

I personally use "git bisect visualize" all the time when I bisect, but it
turns out that that is not a very flexible model. Sometimes I want to do
bisection based on all commits (no pathname limiting), but then visualize
the current bisection tree with just a few pathnames because I _suspect_
those pathnames are involved in the problem but am not totally sure about
them.
And at other times, I want to use other revision parsing logic, none of
which is available with "git bisect visualize".
So this adds "--bisect" as a revision parsing argument, and as a result it
just works with all the normal logging tools. So now I can just do
gitk --bisect --simplify-by-decoration filename-here
etc.

When we show a reflog, we have two ways of naming the entry:
by sequence number (e.g., HEAD@{0}) or by date (e.g.,
HEAD@{10 minutes ago}). There is no explicit option to set
one or the other, but we guess based on whether or not the
user has provided us with a date format, showing them the
date version if they have done so, and the sequence number
otherwise.
This usually made sense if the use did something like "git
log -g --date=relative". However, it didn't make much sense
if the user set the date format using the log.date config
variable; in that case, all of their reflogs would end up as
dates.
This patch records the source of the date format and only
triggers the date-based view if --date= was given on the
command line.

Previously, graph_is_interesting() did not behave quite the same way as
the code in get_revision(). As a result, it would sometimes think
commits were uninteresting, even though get_revision() would return
them. This resulted in incorrect lines in the graph output.
This change creates a get_commit_action() function, which
graph_is_interesting() and simplify_commit() both now use to determine
if a commit will be shown. It is identical to the old simplify_commit()
behavior, except that it never calls rewrite_parents().
This problem was reported by Santi Béjar. The following command
would exhibit the problem before, but now works correctly:
git log --graph --simplify-by-decoration --oneline v1.6.3.3
Previously git graph did not display the output for this command
correctly between f29ac4f and 66996ec, among other places.

Commit de435ac0 changed the behavior of --decorate from printing the
full ref (e.g., "refs/heads/master") to a shorter, more human-readable
version (e.g., just "master"). While this is nice for human readers,
external tools using the output from "git log" may prefer the full
version.
This patch introduces an extension to --decorate to allow the caller to
specify either the short or the full versions.

I do various statistics on git, and one of the things I look at is merges,
because they are often interesting events to count ("how many merges vs
how much 'real development'" kind of statistics). And you can do it with
some fairly straightforward scripting, ie
git rev-list --parents HEAD |
grep ' .* ' |
git diff-tree --always -s --pretty=oneline --stdin |
less -S
will do it.
But I finally got irritated with the fact that we can skip merges with
'--no-merges', but we can't do the trivial reverse operation.
So this just adds a '--merges' flag that _only_ shows merges. Now you can
do the above with just a
git log --merges --pretty=oneline
which is a lot simpler. It also means that we automatically get a lot of
statistics for free, eg
git shortlog -ns --merges
does exactly what you'd want it to do.

This simplifies the logic of rev_compare_tree() by removing a special
case.
It does so by turning the special case of finding a diff to be "all new
files" into a more generic case of "all new" vs "all removed" vs "mixed
changes", so now the code is actually more powerful and more generic, and
the added symmetry actually makes it simpler too.
This makes no changes to any existing behavior, but apart from the
simplification it does make it possible to some day care about whether all
changes were just deletions if we want to. Which we may well want to for
merge handling.

In particular, pushing the "path_name()" call _into_ the show() function
would seem to allow
- more clarity into who "owns" the name (ie now when we free the name in
the show_object callback, it's because we generated it ourselves by
calling path_name())
- not calling path_name() at all, either because we don't care about the
name in the first place, or because we are actually happy walking the
linked list of "struct name_path *" and the last component.
Now, I didn't do that latter optimization, because it would require some
more coding, but especially looking at "builtin-pack-objects.c", we really
don't even want the whole pathname, we really would be better off with the
list of path components.
Why? We use that name for two things:
- add_preferred_base_object(), which actually _wants_ to traverse the
path, and now does it by looking for '/' characters!
- for 'name_hash()', which only cares about the last 16 characters of a
name, so again, generating the full name seems to be just unnecessary
work.
Anyway, so I didn't look any closer at those things, but it did convince
me that the "show_object()" calling convention was crazy, and we're
actually better off doing _less_ in list-objects.c, and giving people
access to the internal data structures so that they can decide whether
they want to generate a path-name or not.
This patch does that, and then for people who did use the name (even if
they might do something more clever in the future), it just does the
straightforward "name = path_name(path, component); .. free(name);" thing.

Here's a less trivial thing, and slightly more dubious one.
I was looking at that "struct object_array objects", and wondering why we
do that. I have honestly totally forgotten. Why not just call the "show()"
function as we encounter the objects? Rather than add the objects to the
object_array, and then at the very end going through the array and doing a
'show' on all, just do things more incrementally.
Now, there are possible downsides to this:
- the "buffer using object_array" _can_ in theory result in at least
better I-cache usage (two tight loops rather than one more spread out
one). I don't think this is a real issue, but in theory..
- this _does_ change the order of the objects printed. Instead of doing a
"process_tree(revs, commit->tree, &objects, NULL, "");" in the loop
over the commits (which puts all the root trees _first_ in the object
list, this patch just adds them to the list of pending objects, and
then we'll traverse them in that order (and thus show each root tree
object together with the objects we discover under it)
I _think_ the new ordering actually makes more sense, but the object
ordering is actually a subtle thing when it comes to packing
efficiency, so any change in order is going to have implications for
packing. Good or bad, I dunno.
- There may be some reason why we did it that odd way with the object
array, that I have simply forgotten.
Anyway, now that we don't buffer up the objects before showing them
that may actually result in lower memory usage during that whole
traverse_commit_list() phase.
This is seriously not very deeply tested. It makes sense to me, it seems
to pass all the tests, it looks ok, but...
Does anybody remember why we did that "object_array" thing? It used to be
an "object_list" a long long time ago, but got changed into the array due
to better memory usage patterns (those linked lists of obejcts are
horrible from a memory allocation standpoint). But I wonder why we didn't
do this back then. Maybe there's a reason for it.
Or maybe there _used_ to be a reason, and no longer is.

Currently when format-patch is used with --attach or --inline the patch
attachment has the SHA1 of the commit for its filename. This replaces
the SHA1 with the filename used by format-patch when outputting to
files.
Fix tests relying on the SHA1 output and add a test showing how the
--suffix option affects the attachment filename output.
