* 'jc/subdir' (early part):
Use cd_to_toplevel in scripts that implement it by hand.
Define cd_to_toplevel shell function in git-sh-setup

merge-recursive: do not report the resulting tree object name
git-revert: Fix die before git-sh-setup defines it.
fix documentation for git-commit --no-verify
This converts scripts that do "cd $(rev-parse --show-cdup)" by
hand to use cd_to_toplevel.
I think git-fetch does not have to go to the toplevel, but that
should be dealt with in a separate patch.

* jc/bare:
Disallow working directory commands in a bare repository.
git-fetch: allow updating the current branch in a bare repository.
Introduce is_bare_repository() and core.bare configuration variable
Move initialization of log_all_ref_updates
If the user tries to run a porcelainish command which requires
a working directory in a bare repository they may get unexpected
results which are difficult to predict and may differ from command
to command.
Instead we should detect that the current repository is a bare
repository and refuse to run the command there, as there is no
working directory associated with it.

When switching branches, we usually first try read-tree to make
sure that we do not lose the local changes and then updated the
HEAD using update-ref. However, we detached and updated HEAD
before these checks, which was quite bad in a repository with
local changes.
Signed-off-by: Junio C Hamano <junkio@cox.net>
Checking for reachability from refs does not help much if the
state we are currently on is somewhere in the middle. We will
lose where we were.
So this makes sureh that HEAD is something directly pointed at
by one of the existing refs (most likely a tag for a user who
has been "sightseeing").

* jc/detached-head:
git-checkout: fix branch name output from the command
git-checkout: safety when coming back from the detached HEAD state.
git-checkout: rewording comments regarding detached HEAD.
git-checkout: do not warn detaching HEAD when it is already detached.
Detached HEAD (experimental)
git-branch: show detached HEAD
git-status: show detached HEAD
cvsimport: cleanup temporary cvsps file
cvsimport: document -S and -L options
cvsimport: skip commits that are too recent (option and documentation)
When switching branches with "git checkout", we internally did $arg^0
(aka $arg^{commit}) suffix but there was no need to.
The improvement is easily visible in the change to an existing
test t/3200-branch.sh in this commit; it was expecting rather
ugly message.

After making commits in the detached HEAD state, if you run "git
checkout" to switch to an existing branch, you will lose your
work. Make sure the switched-to branch is a fast-forward of the
current HEAD, or require -f when switching.

We used to say "you are not on a branch" before the initial
commit. This is incorrect -- the user is on a branch yet to be
born, but its name has been already determined.
Signed-off-by: Junio C Hamano <junkio@cox.net>
This allows "git checkout v1.4.3" to dissociate the HEAD of
repository from any branch. After this point, "git branch"
starts reporting that you are not on any branch. You can go
back to an existing branch by saying "git checkout master", for
example.
This is still experimental. While I think it makes sense to
allow commits on top of detached HEAD, it is rather dangerous
unless you are careful in the current form. Next "git checkout
master" will obviously lose what you have done, so we might want
to require "git checkout -f" out of a detached HEAD if we find
that the HEAD commit is not an ancestor of any other branches.
There is no such safety valve implemented right now.
On the other hand, the reason the user did not start the ad-hoc
work on a new branch with "git checkout -b" was probably because
the work was of a throw-away nature, so the convenience of not
having that safety valve might be even better. The user, after
accumulating some commits on top of a detached HEAD, can always
create a new branch with "git checkout -b" not to lose useful
work done while the HEAD was detached.
We'll see.

The idea and the logic are identical to what "checkout -m" does
when switching the branches. Instead of refusing the two-way
merge, perform the three-way merge between the old head, the
working tree and the new head, and leave the (potentially
conflicted) merge result in the working tree. When the resulting
conflict were too much to handle for the user, there is no easy
way to get that back, so they are stashed away in $GIT_DIR/LOCAL_DIFF
file. We do the same for "git checkout -m".
If this turns out to be a sane thing to do, we probably should
make the common logic between "checkout -m" and this into a
built-in command.

I've seen some users get into situtations where their HEAD
symbolic-ref is pointing at a non-existant ref. (Sometimes this
happens during clone when the remote repository lacks a 'master'
branch.) If this happens the user is unable to use git-checkout
to switch branches as there is no prior commit to merge from.
So instead of giving the user low-level errors about how HEAD
can't be resolved and how not a single revision was given change
the type of checkout to be a force and go through with the user's
request anyway.

When we updated "read-tree -m -u" to be careful about not
removing untracked working tree files, we broke "checkout -m" to
switch between branches.
Signed-off-by: Junio C Hamano <junkio@cox.net>
Earlier we did not consider untracked working tree files
"precious", but we have always considered them fair game to
clobber. These days, branch switching by read-tree is more
careful and tries to protect untracked working tree files. This
caused the following workflow to stop working:
git checkout one-branch-with-file-F
git checkout -f another-without-file-F
git pull . one-branch-with-file-F
Because the second checkout leaves F from the previous state as
untracked file in the working tree, the merge would fail, trying
to protect F from being clobbered.
This changes "git checkout -f" to remove working tree files that
are known to git in the switched-from state but do not exist in
the switched-to state, borrowing the same logic from "reset --hard".

If the user supplies -l to git-branch when creating a new branch
then the new branch's log should be created automatically and the
branch creation should be logged in that log.
Further if a branch is being deleted and it had a log then also
verify that the log was deleted.
Test git-checkout -b foo -l for creating a new branch foo with a
log and checking out that branch.
Fixed git-checkout -b foo -l as the branch variable name was
incorrect in the script.

Switch git checkout -b to use git-update-ref rather than echo and
a shell I/O redirection. This is more in line with typical GIT
commands and allows -b to be logged according to the normal ref
logging rules.
Added -l option to allow users to create the ref log at the same
time as creating a branch.

When we refused to switch branches, we incorrectly showed
differences from the branch we would have switched to.
Signed-off-by: Junio C Hamano <junkio@cox.net>
Earlier, when we switched a branch we used diff-files to show
paths that are dirty in the working tree. But we allow switching
branches with updated index ("read-tree -m -u $old $new" works that
way), and only showing paths that have differences in the working
tree but not paths that are different in index was confusing.
This shows both as modified from the top commit of the branch we
just have switched to.

This shows your working file state when you switch branches. As
a side effect, "git checkout" without any branch name (i.e. stay
on the current branch) becomes a more concise shorthand for the
"git status" command.

* Instead of going interactive, introduce a command line switch
'-m' to allow merging changes when normal two-way merge by
read-tree prevents branch switching.
* Leave the unmerged stages intact if automerge fails, but
reset index entries of cleanly merged paths to that of the
new branch, so that "git diff" (not "git diff HEAD") would
show the local modifications.
* Swap the order of trees in read-tree three-way merge used in
the fallback, so that `git diff` to show the conflicts become
more natural.
* Describe the new option and give more examples in the documentation.

When switching branches, if the working tree has a local
modification at paths that are different between current and new

git-checkout does two very different things, and what they
should do when run from subdirectory are quite different.
It does not make any sense to run the one that switches the
current head from anywhere other than the toplevel:
git-checkout [-f] <branch>
git-checkout [-b <branch>] <committish>
We could of course chdir to top and do the whole-tree checkout
in git-checkout, but the point is the operation does not make
sense on a partial tree. The whole tree is checked out.
The other form is to update the index file and working tree file
selectively:
git-checkout <treeish> <file>... ;# out of tree to index and file
git-checkout -- <file>... ;# out of index to file
This form _does_ make sense to run from subdirectory; and I
myself often wish we supported this.
So here is a patch to do both.

git-update-index --index-info can almost be usable to read from ls-tree
output to update the index (and not the working tree file) to HEAD commit,
but not quite. It was designed to read from git-apply --index-info
output, and does not want " blob " in ls-tree output. Accept that as well.
This lets us update "git-checkout <ent> <path>" that used to filter the
extra " blob " string out. Noted by Luben.

This adds the counterpart of git-update-ref that lets you read
and create "symbolic refs". By default it uses a symbolic link
to represent ".git/HEAD -> refs/heads/master", but it can be compiled
to use the textfile symbolic ref.
The places that did 'readlink .git/HEAD' and 'ln -s refs/heads/blah
.git/HEAD' have been converted to use new git-symbolic-ref command, so
that they can deal with either implementation.
