It appears the fingerprinting itself is too expensive to be worth doing

This bug was reported by Yann Dirson, and results in an 'Error:
expected boolean value but got ""' dialog when scrolling to the bottom
of the graph under some circumstances. The issue is that git-rev-list
isn't outputting all the boundary commits when it is asked for commits
affecting only certain files. We already cope with that by adding the
missing boundary commits in addextraid, but there we weren't adding a
0 to the end of the commitlisted list when we added the extra id to
the end of the displayorder list.
This fixes it by appending 0 to commitlisted in addextraid, thus keeping
commitlisted and displayorder in sync.

Previously, if we switched away from a view before we had finished
reading the git-rev-list output for it and laying out the graph, we
would discard the partially-laid-out graph and reread it from
scratch if we switched back to the view. With this, we preserve the
state of the partially-laid-out graph in viewdata($view) and restore
it if we switch back. The pipe to git-rev-list remains open but we
just don't read from it any more until we switch back to that view.
This also makes linesegends a list rather than an array, which turns
out to be slightly faster, as well as being easier to save and restore.
The `update' menu item now kills the git-rev-list process if there is
one still running when we do the update.

This uses the "--no-walk" flag that I never actually implemented (but I'm
sure I mentioned it) to make "git show" be essentially the same thing as
"git whatchanged --no-walk".
It just refuses to add more interesting parents to the revision walking
history, so you don't actually get any history, you just get the commit
you asked for.
I was going to add "--no-walk" as a real argument flag to git-rev-list
too, but I'm not sure anybody actually needs it. Although it might be
useful for porcelain, so I left the door open.

The big option parser unification broke rev-list the big way;

Signed-off-by: Junio C Hamano <junkio@cox.net>
Merging all three option parsers related to whatchanged is
unarguably the right thing, but the fallout was too big to scare
me away. Let's try it once again, but once step at time.
This splits out init_revisions() call from setup_revisions(), so
that the callers can set different defaults to match the
traditional benaviour.
The rev-list command is still broken in a big way, which is the

The "--help" argument is special, in that it is (along with "--version")
in that is taken by the "git" program itself rather than the sub-command,
and thus we've had the syntax "git --help cmd".
However, as anybody who has ever used CVS or some similar devil-spawn
program, it's confusing as h*ll when options before the sub-command act
differently from options after the sub-command, so this quick hack just
makes it acceptable to do "git cmd --help" instead, and get the exact same
result.
It may be hacky, but it's simple and does the trick.
Of course, this does not help if you use one of the non-builtin commands
without using the "git" helper. Ie you won't be getting a man-page just
because you do "git-rev-list --help". Don't expect us to be quite _that_
helpful.

I missed that "git-diff-* --stat" spits out three-dash separator
on its own without being asked. Remove it.
When we output commit log followed by diff, perhaps --patch-with-stat,
for downstream consumer, we _would_ want the three-dash between
the message and the diff material, but that logic belongs to the
caller, not diff generator.

Built-in git-whatchanged
Now "git log" is in reusable shape, add "git whatchanged" which
essentially is a synonym with different default for people whose
fingers are already trained.
There is a subtle difference from the shell-script version; the
first line of each entry is now "commit <object name>", instead
of "diff-tree <object name> (from <object name>)." I suspect
that showing the parent name that way is useful, so this may be
something we would want to fix (the user can say --pretty=raw to
get that information but that is a bit ugly).

Merging of the log-tree-opt structure with rev-info structure
did not work out very well and it broke things that did not want
diff options and/or rev options.
This is an alternative approach to define a combined interface
that can be used by commands that wants both. The use of it is
opt-in to reduce the risk of breaking existing programs.
We might want to slurp "setup_revisions() places things in
pending objects list" part from Linus's earlier attempt.

* lt/logopt:
Fix up rev-list option parsing.
Fix up default abbrev in setup_revisions() argument parser.
Common option parsing for "git log --diff" and friends
This basically does a few things that are sadly somewhat interdependent,
and nontrivial to split out
- get rid of "struct log_tree_opt"
The fields in "log_tree_opt" are moved into "struct rev_info", and all
users of log_tree_opt are changed to use the rev_info struct instead.
- add the parsing for the log_tree_opt arguments to "setup_revision()"
- make setup_revision set a flag (revs->diff) if the diff-related
arguments were used. This allows "git log" to decide whether it wants
to show diffs or not.
- make setup_revision() also initialize the diffopt part of rev_info
(which we had from before, but we just didn't initialize it)
- make setup_revision() do all the "finishing touches" on it all (it will
do the proper flag combination logic, and call "diff_setup_done()")
Now, that was the easy and straightforward part.
The slightly more involved part is that some of the programs that want to
use the new-and-improved rev_info parsing don't actually want _commits_,
they may want tree'ish arguments instead. That meant that I had to change
setup_revision() to parse the arguments not into the "revs->commits" list,
but into the "revs->pending_objects" list.
Then, when we do "prepare_revision_walk()", we walk that list, and create
the sorted commit list from there.
This actually cleaned some stuff up, but it's the less obvious part of the
patch, and re-organized the "revision.c" logic somewhat. It actually paves
the way for splitting argument parsing _entirely_ out of "revision.c",
since now the argument parsing really is totally independent of the commit
walking: that didn't use to be true, since there was lots of overlap with
get_commit_reference() handling etc, now the _only_ overlap is the shared
(and trivial) "add_pending_object()" thing.
However, I didn't do that file split, just because I wanted the diff
itself to be smaller, and show the actual changes more clearly. If this
gets accepted, I'll do further cleanups then - that includes the file
split, but also using the new infrastructure to do a nicer "git diff" etc.
Even in this form, it actually ends up removing more lines than it adds.
It's nice to note how simple and straightforward this makes the built-in
"git log" command, even though it continues to support all the diff flags
too. It doesn't get much simpler that this.
I think this is worth merging soonish, because it does allow for future
cleanup and even more sharing of code. However, it obviously touches
"revision.c", which is subtle. I've tested that it passes all the tests we
have, and it passes my "looks sane" detector, but somebody else should
also give it a good look-over.

I noticed bisect does not work well without both good and bad.
Running this script in git.git repository would give you quite
different results:
#!/bin/sh
initial=e83c5163316f89bfbde7d9ab23ca2e25604af290
mid0=`git rev-list --bisect ^$initial --all`
git rev-list $mid0 | wc -l
git rev-list ^$mid0 --all | wc -l
mid1=`git rev-list --bisect --all`
git rev-list $mid1 | wc -l
git rev-list ^$mid1 --all | wc -l
The $initial commit is the very first commit you made. The
first midpoint bisects things evenly as designed, but the latter
does not.
The reason I got interested in this was because I was wondering
if something like the following would help people converting a
huge repository from foreign SCM, or preparing a repository to
be fetched over plain dumb HTTP only:
#!/bin/sh
N=4
P=.git/objects/pack
bottom=
while test 0 \< $N
do
N=$((N-1))
if test -z "$bottom"
then
newbottom=`git rev-list --bisect --all`
else
newbottom=`git rev-list --bisect ^$bottom --all`
fi
if test -z "$bottom"
then
rev_list="$newbottom"
elif test 0 = $N
then
rev_list="^$bottom --all"
else
rev_list="^$bottom $newbottom"
fi
p=$(git rev-list --unpacked --objects $rev_list |
git pack-objects $P/pack)
git show-index <$P/pack-$p.idx | wc -l
bottom=$newbottom
done
The idea is to pack older half of the history to one pack, then
older half of the remaining history to another, to continue a
few times, using finer granularity as we get closer to the tip.
This may not matter, since for a truly huge history, running
bisect number of times could be quite time consuming, and we
might be better off running "git rev-list --all" once into a
temporary file, and manually pick cut-off points from the
resulting list of commits. After all we are talking about
"approximately half" for such an usage, and older history does
not matter much.
