I just realized I did not support ref name completion for git-cherry.
This tool is just too useful to contributors who submit patches
upstream by email; completion support for it is very handy.

This particular use of git-rebase to remove a single commit or a
range of commits from the history of a branch recently came up on
the mailing list. Documenting the example should help other users
arrive at the same solution on their own.
It also was not obvious to the newcomer that git-rebase is able to
accept any commit for --onto <newbase> and <upstream>. We should
at least minimally document this, as much of the language in
git-rebase's manpage refers to 'branch' rather than 'committish'.

We at least know that the test as written has a problem in an
environment where "touch '$p'; ls | fgrep '$p'" fails, and have
a clear understand why it fails.
This tests if the filesystem has that particular issue we know "git
add" has a problem with, and skips the test in such an environment.
This way, we might catch issues "git add" might have in other environments.

This reverts commit 80c797764a6b6a373f0f1f47d7f56b0d950418a9.
Back when I committed this, it seemed to be a good idea. People
who always use remote tracking branches can optionally use the
local name they happen to use to specify what to merge, which meant
that I did not have to teach them why we use the name at the remote
side every time they are confused.
But allowing it seems to break other people's scripts. The real
solution is not to allow more ways to express the same thing, but
to educate people to use the right syntax.

* np/dreflog:
show-branch -g: default to the current branch.
Let git-checkout always drop any detached head
Enable HEAD@{...} and make it independent from the current branch
scan reflogs independently from refs
add reflog when moving HEAD to a new branch
create_symref(): do not assume pathname from git_path() persists long enough
add logref support to git-symbolic-ref
move create_symref() past log_ref_write()
add reflog entries for HEAD when detached
enable separate reflog for HEAD
lock_ref_sha1_basic(): remember the original name of a ref when resolving it
make reflog filename independent from struct ref_lock

We used to refuse leaving a detached HEAD when it wasn't matching an
existing ref so not to lose any commit that might have been performed
while not on any branch (unless -f was provided).
But this protection was completely bogus since it was still possible
to move to HEAD^ while still remaining detached but losing the last
commit anyway if there was one.
Now that we have a proper reflog for HEAD it is best to simply remove
that bogus (and admitedly annoying) protection and simply display the
last HEAD position instead. If one wants to recover a lost detached
state then it can be retrieved from the HEAD reflog.

Being lazy to rely on the cycling N buffers mkpath() and friends
return is nice in general, but it makes it too easy to introduce
new bugs that are "mysterious".
Introduction of read_ref() in create_symref() after calling
git_path() to get the git_HEAD value (i.e. the path to create a
new symref at) consumed more than the available buffers and
broke a later call to mkpath() that derives lockpath from it.

When using --reference to borrow objects from a neighbouring
repository while cloning, we copy the entire set of refs under
temporary "refs/reference-tmp/refs" space and set up the object
alternates. However, a textual symref copied this way would not
point at the right place, and causes later steps to emit error
messages (which is harmless but still alarming). This is most
visible when using a clone created with the separate-remote
layout as a reference, because such a repository would have
refs/remotes/origin/HEAD with 'ref: refs/remotes/origin/master'
as its contents.
Although we do not create symbolic-link based refs anymore, they
have the same problem because they are always supposed to be
relative to refs/ hierarchy (we dereference by hand, so it only
is good for HEAD and nothing else).
In either case, the solution is simply to remove them after
copying under refs/reference-tmp; if a symref points at a true
ref, that true ref itself is enough to ensure that objects
reachable from it do not needlessly get fetched.

Because our use of -o nospace prevents bash from adding a trailing space
when a completion is unique and has been fully completed, we need to
perform this addition on our own. This (large) change converts all
existing uses of compgen to our wrapper __gitcomp which attempts to
handle this by tacking a trailing space onto the end of each offered
option.

Because we use the nospace option for our completion function for
the main 'git' wrapper bash won't automatically add a space after a
unique completion has been made by the user. This has been pointed
out in the past by Linus Torvalds as an undesired behavior. I agree.
We have to use the nospace option to ensure path completion for
a command such as `git show` works properly, but that breaks the
common case of getting the space for a unique completion. So now we
set IFS=$'\n' (linefeed) and add a trailing space to every possible
completion option. This causes bash to insert the space when the
completion is unique.

The new --interactive mode of git-add can be very useful, so users
will probably want to have completion for it.
Likewise the new git-add--interactive executable is actually a
plumbing command. Its invoked by `git add --interactive` and is
not intended to be invoked directly by the user. Therefore we
should hide it from the list of available Git commands.

Now that git-show is capable of displaying any file content from any
revision and is the approved Porcelain-ish level method of doing so,
cat-file should no longer be classified as a user-level utility by
the bash completion package.
I'm also classifying the new git-reflog command as plumbing for the
time being as there are no subcommands which are really useful to
the end-user. git-gc already invokes `git reflog expire --all`,
which makes it rather unnecessary for the user to invoke it directly.

The short options (-l, -f, -d) for git-branch are rather silly to
include in the completion generation as these options must be fully
typed out by the user and most users already know what the options
are anyway, so including them in the suggested completions does
not offer huge value. (The same goes for git-checkout and git-diff.)

My earlier fix (8371234e) to delete renamed tracked files from the
working directory also caused merge-recursive to delete untracked
files that were in the working directory.
The problem here is merge-recursive is deleting the working directory
file without regard for which branch it was associated with. What we
really want to do during a merge is to only delete files that were
renamed by the branch we are merging into the current branch,
and that are still tracked by the current branch. These files
definitely don't belong in the working directory anymore.
Anything else is either a merge conflict (already handled in other
parts of the code) or a file that is untracked by the current branch
and thus is not even participating in the merge. Its this latter
class that must be left alone.
For this fix to work we are now assuming that the first non-base
argument passed to git-merge-recursive always corresponds to the
working directory. This is already true for all in-tree callers
of merge-recursive. This assumption is also supported by the
long time usage message of "<base> ... -- <head> <remote>", where
"<head>" is implied to be HEAD, which is generally assumed to be
the current tree-ish.

I was reading the tutorial and noticed that we say this:
Also, don't use "git reset" on a publicly-visible branch that
other developers pull from, as git will be confused by history
that disappears in this way.
I do not think this is a good explanation. For example, if we
do this:
(1) I build a series and push it out.
---o---o---o---j
(2) Alice clones from me, and builds two commits on top of it.
---o---o---o---j---a---a
(3) I rewind one and build a few, and push them out.
---o---o---o...j
\
h---h---h---h
(4) Alice pulls from me again:
---o---o---o---j---a---a---*
\ /
h---h---h---h
Contrary to the description, git will happily have Alice merge
between the two branches, and never gets confused.
Maybe I did not want to have 'j' because it was an incomplete
solution to some problem, and Alice may have fixed it up with
her changes, while I abandoned that approach I started with 'j',
and worked on something completely unrelated in the four 'h'
commits. In such a case, the merge Alice would make would be
very sensible, and after she makes the merge if I pull from her,
the world will be perfect. I started something with 'j' and
dropped the ball, Alice picked it up and perfected it while I
went on to work on something else with 'h'. This would be a
perfect example of distributed parallel collaboration. There is
nothing confused about it.
The case the rewinding becomes problematic is if the work done
in 'h' tries to solve the same problem as 'j' tried to solve in
a different way. Then the merge forced on Alice would make her
pick between my previous attempt with her fixups (j+a) and my
second attempt (h). If 'a' commits were to fix up what 'j'
started, presumably Alice already studied and knows enough about
the problem so she should be able to make an informed decision
to pick between what 'j+a' and 'h' do.
A lot worse case is if Alice's work is not at all related to
what 'j' wanted to do (she did not mean to pick up from where I
left off -- she just wanted to work on something different).
Then she would not be familiar enough with what 'j' and 'h'
tried to achieve, and I'd be forcing her to pick between the
two. Of course if she can make the right decision, then again
that is a perfect example of distributed collaboration, but that
does not change the fact that I'd be forcing her to clean up my
mess.

Even when -l is not given from the command line, the repository
may have the configuration variable core.logallrefupdates set,
or an old-timer might have done ": >.git/logs/refs/heads/new"
before running "git branch new". In these cases, the code gave
an uninitialized msg[] from the stack to be written out as the
reflog message.
This also passes a different message when '-f' option is used.
Saying "git branch -f branch some-commit" is a moral equilvalent
of doing "git-reset some-commit" while on the branch.

Matthias Lederhofer identified a race condition where a Git reader
process was able to locate an object in a packed_git index, but
was then preempted while a `git repack -a -d` ran and completed.
By the time the reader was able to seek in the packfile to get the
object data, the packfile no longer existed on disk.
In this particular case the reader process did not attempt to
open the packfile before it was deleted, so it did not already
have the pack_fd field popuplated. With the packfile itself gone,
there was no way for the reader to open it and fetch the data.
I'm fixing the race condition by teaching find_pack_entry to ignore
a packed_git whose packfile is not currently open and which cannot
be opened. If none of the currently known packs can supply the
object, we will return 0 and the caller will decide the object is
not available. If this is the first attempt at finding an object,
the caller will reprepare_packed_git and try again. If it was
the second attempt, the caller will typically return NULL back,
and an error message about a missing object will be reported.
This patch does not address the situation of a reader which is
being starved out by a tight sequence of `git repack -a -d` runs.
In this particular case the reader will try twice, probably fail
both times, and declare the object in question cannot be found.
As it is highly unlikely that a real world `git repack -a -d` can
complete faster than a reader can open a packfile, so I don't think
this is a huge concern.

Because I want to reuse open_packed_git in a context where I don't
want the process to die if the packfile in question is bogus, I'm
changing its behavior to return error("...") rather than die("...")
when it detects something is wrong with the packfile it was given.
Right now we still must die out of use_pack should open_packed_git
fail, as none of use_pack's callers are prepared to handle a failure
from that function.

After staring at the comment and the associated for loop, I
realized the comment was completely bogus. The section of
code its talking about is trying to avoid duplicate mapping
of the same packfile.
