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.)

[torvalds@nehalem git]$ em builtin-shor<tab>
builtin-shortlog.c builtin-shortlog.o

[torvalds@nehalem git]$ em builtin/shor<tab> [type]
shortlog.c shortlog.o
[torvalds@nehalem git]$ em builtin/shortlog.c
which doesn't seem all that different, but not having that annoying
break in "Display all 180 possibilities?" is quite a relief.
NOTE! If you do this in a clean tree (no object files etc), or using an
editor that has auto-completion rules that ignores '*.o' files, you
won't see that annoying 'Display all 180 possibilities?' message - it
will just show the choices instead. I think bash has some cut-off
around 100 choices or something.
So the reason I see this is that I'm using an odd editory, and thus
don't have the rules to cut down on auto-completion. But you can
simulate that by using 'ls' instead, or something similar.

Historically, any grep filter in "git log" family of commands were taken
as restricting to commits with any of the words in the commit log message.
However, the user almost always want to find commits "done by this person
on that topic". With "--all-match" option, a series of grep patterns can
be turned into a requirement that all of them must produce a match, but
that makes it impossible to ask for "done by me, on either this or that"
with:
log --author=me --committer=him --grep=this --grep=that
because it will require both "this" and "that" to appear.
Change the "header" parser of grep library to treat the headers specially,
and parse it as:
(all-match-OR (HEADER-AUTHOR me)
(HEADER-COMMITTER him)
(OR
(PATTERN this)
(PATTERN that) ) )
Even though the "log" command line parser doesn't give direct access to
the extended grep syntax to group terms with parentheses, this change will
cover the majority of the case the users would want.
This incidentally revealed that one test in t7002 was bogus. It ran:
log --author=Thor --grep=Thu --format='%s'
and expected (wrongly) "Thu" to match "Thursday" in the author/committer
date, but that would never match, as the timestamp in raw commit buffer
does not have the name of the day-of-the-week.

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

The ones that stay "plain" arguments were chosen on the grounds that

The option "QUIET" primarily meant "find if we have _any_ difference as
quick as possible and report", which means we often do not even have to
look at blobs if we know the trees are different by looking at the higher
level (e.g. "diff-tree A B"). As a side effect, because there is no point
showing one change that we happened to have found first, it also enables
NO_OUTPUT and EXIT_WITH_STATUS options, making the end result look quiet.
Rename the internal option to QUICK to reflect this better; it also makes
grepping the source tree much easier, as there are other kinds of QUIET

because we will need to get more information from this function in
some later patches.
The new "int *count" parameter gives the number of commits left after
the skipped commit have been filtered out.
The new "int *skipped_first" parameter tells us if the first commit
in the list has been skipped. Note that using this parameter also
changes the behavior of the function if the first commit is indeed
skipped. Because we assume that in this case we will want all the
filtered commits, not just the first one, even if "show_all" is not
set.
So using a not NULL "skipped_first" parameter really means that we
plan to choose to test another commit than the first non skipped
one if the first commit in the list is skipped. That in turn means
that, in case the first commit is skipped, we have to return a
fully filtered list.

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.

This patch teaches "git rev-list --bisect-vars" to output an estimate

the other variables it already outputs.
This patch also makes "git-bisect.sh" display this number of steps left
_after the current one_, along with the estimate of the number of

Here is a table to help analyse what should be the best estimate for
the number of bisect steps left.
N : linear case --> probabilities --> best
-------------------------------------------------------------
1 : G-B --> 0 --> 0
2 : G-U1-B --> 0 --> 0
3 : G-U1-U2-B --> 0(1/3) 1(2/3) --> 1
4 : G-U1-U2-U3-B --> 1 --> 1
5 : G-U1-U2-U3-U4-B --> 1(3/5) 2(2/5) --> 1
6 : G-U1-U2-U3-U4-U5-B --> 1(2/6) 2(4/6) --> 2
7 : G-U1-U2-U3-U4-U5-U6-B --> 1(1/7) 2(6/7) --> 2
8 : G-U1-U2-U3-U4-U5-U6-U7-B --> 2 --> 2
9 : G-U1-U2-U3-U4-U5-U6-U7-U8-B --> 2(7/9) 3(2/9) --> 2
10: G-U1-U2-U3-U4-U5-U6-U7-U8-U9-B --> 2(6/10)3(4/10)--> 2
In the column "N", there is the number of revisions that could _now_
be the first bad commit we are looking for.
The "linear case" column describes the linear history corresponding to
the number in column N. G means good, B means bad, and Ux means
unknown. Note that the first bad revision we are looking for can be
any Ux or B.
In the "probabilities" column, there are the different outcomes in
number of steps with the odds of each outcome in parenthesis
corresponding to the linear case.
The "best" column gives the most accurate estimate among the different
outcomes in the "probabilities" column.
We have the following:
best(2^n) == n - 1
and for any x between 0 included and 2^n excluded, the probability for
n - 1 steps left looks like:
P(2^n + x) == (2^n - x) / (2^n + x)
and P(2^n + x) < 0.5 means 2^n < 3x
So the algorithm used in this patch calculates 2^n and x, and then
choose between returning n - 1 and n.

This has been broken in v1.6.0 due to the reorganization of
the revision option parsing code. The "-i" is completely

What happens is that the code for "-i" looks for
revs->grep_filter; if it is NULL, we do nothing, since there
are no grep filters. But that is obviously not correct,
since we want it to influence the later --grep option. Doing
it the other way around works, since "-i" just impacts the
existing grep_filter option.
Instead, we now always initialize the grep_filter member and
just fill in options and patterns as we get them. This means
that we can no longer check grep_filter for NULL, but
instead must check the pattern list to see if we have any

It's really not very easy to visualize the commit walker, because - on
purpose - it obvously doesn't show the uninteresting commits!
This adds a "--show-all" flag to the revision walker, which will make
it show uninteresting commits too, and they'll have a '^' in front of
them (it also fixes a logic error for !verbose_header for boundary
commits - we should show the '-' even if left_right isn't shown).
A separate patch to gitk to teach it the new '^' was sent
to paulus. With the change in place, it actually is interesting
even for the cases that git doesn't have any problems with, ie
for the kernel you can do:
gitk -d --show-all v2.6.24..
and you see just how far down it has to parse things to see it all. The
use of "-d" is a good idea, since the date-ordered toposort is much better
at showing why it goes deep down (ie the date of some of those commits
after 2.6.24 is much older, because they were merged from trees that
weren't rebased).
So I think this is a useful feature even for non-debugging - just to
visualize what git does internally more.
When it actually breaks out due to the "everybody_uninteresting()"
case, it adds the uninteresting commits (both the one it's looking at
now, and the list of pending ones) to the list
This way, we really list *all* the commits we've looked at.
Because we now end up listing commits we may not even have been parsed
at all "show_log" and "show_commit" need to protect against commits
that don't have a commit buffer entry.
That second part is debatable just how it should work. Maybe we shouldn't
show such entries at all (with this patch those entries do get shown, they
just don't get any message shown with them). But I think this is a useful
case.

But an object can get the "parsed" flag for other reasons.
Which means that "TREECHANGE" has the wrong polarity.
This changes the way how the path pruning logic marks an
uninteresting commits. From now on, we consider a commit
interesting by default, and explicitly mark the ones we decided
to prune. The flag is renamed to "TREESAME".
Then, this fixes the logic to show the early output with
incomplete pruning. It basically says "a commit that has
TREESAME set is kind-of-UNINTERESTING", but obviously in a
different way than an outright UNINTERESTING commit. Until we
parse and examine enough parents to determine if a commit
becomes surely "kind-of-UNINTERESTING", we avoid rewriting

This was cherry-picked from the fix in 'master'

This removes the unnecessary indirection of "revs->prune_fn",
since that function is always the same one (or NULL), and there
is in fact not even an abstraction reason to make it a function
(i.e. its not called from some other file and doesn't allow us
to keep the function itself static or anything like that).
It then just replaces it with a bit that says "prune or not",
and if not pruning, every commit gets TREECHANGE.
That in turn means that
- if (!revs->prune_fn || (flags & TREECHANGE))
- if (revs->prune_fn && !(flags & TREECHANGE))
just become
- if (flags & TREECHANGE)
- if (!(flags & TREECHANGE))
respectively.
Together with adding the "single_parent()" helper function, the "complex"
conditional now becomes
if (!(flags & TREECHANGE) && rev->dense && single_parent(commit))
continue;
Also indirection of "revs->dense" checking is thrown away the
same way, because TREECHANGE bit is set appropriately now.

When the body of the commit log message contains a non-ASCII character,
format-patch correctly emitted the encoding header to mark the resulting
message as such. However, if the original message was fully ASCII, the
command line switch "-s" was given to add a new sign-off, and
the signer's name was not ASCII only, the resulting message would have
contained non-ASCII character but was not marked as such.
