git-send-email.
git-send-email, when used with --compose, provided the user with a mbox-format
file to edit. Some users, however, were confused by the leading, blank, "From
" line, so this change puts the value that will appear on the From: line of the
actual email on this line, along with a note that the line is ignored.

A misguided attempt to show logs at all time was inserted only to
the documentation of this flag. Worse yet, it was not even implemented,
causing more confusion. Drop it.
We might want to have an option to show --pretty even when there is no
diff output, but that is applicable to all forms of diff, not just --cc.

The code misplaced a raw hunk that consists of solely deleted
lines by one line. This showed e.g. Len's 12-way octopus
(9fdb62af in the linux-2.6), kernel/power/disk.c, hunk starting
at line 95, incorrectly.

The earlier change implemented "only two version" check but
without checking if the change rewrites from all the parents.
This implements a check to make sure that a change introduced
by the merge from all the parents is caught to be interesting.

Earlier logic was discarding hunks that has difference from only
one parent or the same difference from all but one parent. This
changes it to check if the differences on all lines are from the
same sets of parents. This discards more uninteresting hunks
and seems to match expectations more naturally.

When dealing with an insanely large Octopus, it is possible to
optimize by noticing that more than one parents have the same
blob and avoid running diff between a parent and the merge
result by reusing an earlier result.

So far, e.g. git-update-index --refresh was basically uninterruptable
by ctrl-c, since it hooked the SIGINT handler, but that handler would
only unlink the lockfile but not actually quit. This makes it propagate
the signal to the default handler.
Note that I expected it to work without resetting the signal handler to
SIG_DFL, but without that it ended in an infinite loop of tgkill()s -
is my glibc violating SUS or what?

Showing the same parent more than once for a commit does not
make much sense downstream, so stop it.
This can happen with an incorrectly made merge commit that
merges the same parent twice, but can happen in an otherwise
sane development history while squishing the history by taking
into account only commits that touch specified paths.
For example,
$ git rev-list --max-count=1 --parents addafaf -- rev-list.c
would have to show this commit ancestry graph:
.---o---.
/ \
.---*---o---.
/ 93b74bc \
---*---o---o-----o---o-----o addafaf
d8f6b34 \ /
.---o---o---.
\ /
.---*---.
3815f42
where 5 independent development tracks, only two of which have
changes in the specified paths since they forked. The last
change for the other three development tracks was done by the
same commit before they forked, and we were showing that three
times.

Both -n<n> and -n <n> are supported. POSIX versions of head(1) and

--max-count to be a commonly used option, and also similar in spirit to
head/tail, so I decided to make life easier on my worn out (and lazy :)

Here's some changes to the cvs-migration.txt. As usual, in my attempt
to make things clearer someone may have found I've made them less so, or
I may have just gotten something wrong; so any review is welcomed.
I can break up this sort of thing into smaller steps if preferred, the
monolothic patch is just a bit simpler for me for this sort of
thing.
I moved the material describing shared repository management from
core-tutorial.txt to cvs-migration.txt, where it seems more appropriate,
and combined two sections to eliminate some redundancy.
I also revised the earlier sections of cvs-migration.txt, mainly trying
to make it more concise.
I've left the last section of cvs-migration.txt (on CVS annotate
alternatives) alone for now.

The example hook barfs on the initial import. Ideally it should
produce a diff from an empty tree, but for now let's stop at
squelching the bogus error message. Often an initial import
involves tons of badly formatted files from foreign SCM, so not
complaining about them like this patch does might actually be a
better idea than enforcing the "Perfect Patch" format on them.

The latest update to avoid misspelled revs interfered when we
were not interested in parsing non flags or arguments not meant
for rev-list. This makes these two forms work again:
git whatchanged -- git-fetch-script
We could enable "!def" in the part this change touches to make
the above work without '--', but then it would cause misspelled
v2.6.14..v2.6.16 to be given to diff-tree and defeats the whole
point of the previous fix.

The usage of rev-parse to serve as a flag/option parser
for git-whatchanged and other commands have serious limitation
that the flags cannot be something that is supported by
rev-parse itself, and it cannot worked around easily. Since
this is rarely used "poor-man's describe", rename the option for
now as an easier workaround.

The one thing I've considered doing (I really should) is to add a "stop
when you don't find the file" option to "git-rev-list". This patch does
some of the work towards that: it removes the "parent" thing when the
file disappears, so a "git annotate" could do do something like
git-rev-list --remove-empty --parents HEAD -- "$filename"
and it would get a good graph that stops when the filename disappears
(it's not perfect though: it won't remove all the unintersting commits).
It also simplifies the logic of finding tree differences a bit, at the
cost of making it a tad less efficient.
The old logic was two-phase: it would first simplify _only_ merges tree as
it traversed the tree, and then simplify the linear parts of the remainder
independently. That was pretty optimal from an efficiency standpoint
because it avoids doing any comparisons that we can see are unnecessary,
but it made it much harder to understand than it really needed to be.
The new logic is a lot more straightforward, and compares the trees as it
traverses the graph (ie everything is a single phase). That makes it much
easier to stop graph traversal at any point where a file disappears.
As an example, let's say that you have a git repository that has had a
file called "A" some time in the past. That file gets renamed to B, and
then gets renamed back again to A. The old "git-rev-list" would show two
commits: the commit that renames B to A (because it changes A) _and_ as
its parent the commit that renames A to B (because it changes A).
With the new --remove-empty flag, git-rev-list will show just the commit
that renames B to A as the "root" commit, and stop traversal there
(because that's what you want for "annotate" - you want to stop there, and
for every "root" commit you then separately see if it really is a new
file, or if the paths history disappeared because it was renamed from some
other file).
With this patch, you should be able to basically do a "poor mans 'git
annotate'" with a fairly simple loop:
push("HEAD", "$filename")
while (revision,filename = pop()) {
for each i in $(git-rev-list --parents --remove-empty $revision -- "$filename")
pseudo-parents($i) = git-rev-list parents for that line
if (pseudo-parents($i) is non-empty) {
show diff of $i against pseudo-parents
continue
}
/* See if the _real_ parents of $i had a rename */
parent($i) = real-parent($i)
if (find-rename in $parent($i)->$i)
push $parent($i), "old-name"
}
which should be doable in perl or something (doing stacks in shell is just
too painful to be worth it, so I'm not going to do this).
Anybody want to try?

This ports the "combined diff" to diff-files so that differences
to the working tree files since stage 2 and stage 3 are shown
the same way as combined diff output from diff-tree for the
merge commit would be shown if the current working tree files
are committed.
