08d595dc1c checkout: add --ignore-skip-worktree-bits in sparse checkout mode
"git checkout -- <paths>" is usually used to restore all modified
files in <paths>. In sparse checkout mode, this command is overloaded
with another meaning: to add back all files in <paths> that are
excluded by sparse patterns.

As the former makes more sense for day-to-day use. Switch it to the
default and the latter enabled with --ignore-skip-worktree-bits.

While at there, add info/sparse-checkout to gitrepository-layout.txt

d6e1466095 checkout: abbreviate hash in suggest_reattach
After printing the list of left-behind commits (with abbreviated
hashes), use an abbreviated hash in the suggested 'git branch' command;
there's no point in outputting a full 40-character hex string in some

e721c1544f checkout: avoid unnecessary match_pathspec calls
In checkout_paths() we do this

 - for all updated items, call match_pathspec
 - for all items, call match_pathspec (inside unmerge_cache)
 - for all items, call match_pathspec (for showing "path .. is unmerged)
 - for updated items, call match_pathspec and update paths

That's a lot of duplicate match_pathspec(s) and the function is not
exactly cheap to be called so many times, especially on large indexes.
This patch makes it call match_pathspec once per updated index entry,
save the result in ce_flags and reuse the results in the following
loops.

The changes in 0a1283b (checkout $tree $path: do not clobber local
changes in $path not in $tree - 2011-09-30) limit the affected paths
to ones we read from $tree. We do not do anything to other modified
entries in this case, so the "for all items" above could be modified
to "for all updated items". But..

The command's behavior now is modified slightly: unmerged entries that
match $path, but not updated by $tree, are now NOT touched.  Although
this should be considered a bug fix, not a regression. A new test is
added for this change.

And while at there, free ps_matched after use.

The following command is tested on webkit, 215k entries. The pattern
is chosen mainly to make match_pathspec sweat:

git checkout -- "*[a-zA-Z]*[a-zA-Z]*[a-zA-Z]*"

        before      after
real    0m3.493s    0m2.737s

afa8c07a26 checkout: print a message when switching unborn branches
When we switch to a new branch using checkout, we usually output a
message indicating what happened. However, when we switch from an unborn
branch to a new branch, we do not print anything, which may leave the
user wondering what happened.

The reason is that the unborn branch is a special case (see abe1998),
and does not follow the usual switch_branches code path. Let's add a
similar informational message to the special case to match the usual
code path.

The option parsing of "git checkout" had error checking, dwim and
defaulting missing options, all mixed in the code, and issuing an
appropriate error message with useful context was getting harder.
Reorganize the code and allow giving a proper diagnosis when the

for a branch).

b6312c27a0 checkout: reorder option handling
checkout operates in three different modes. On top of that it tries to
be smart by guessing the branch name for switching. This results in
messy option handling code. This patch reorders it so that

 - cmd_checkout() is responsible for parsing, preparing input and
   determining mode

 - Code of each mode is in checkout_paths() and checkout_branch(),
   where sanity checks are performed

Another slight improvement is always print branch name (or commit
name) when printing errors related ot them. This helps catch the case
where an option is mistaken as branch/commit.

28452655af diff_setup_done(): return void
diff_setup_done() has historically returned an error code, but lost
the last nonzero return in 943d5b7 (allow diff.renamelimit to be set
regardless of -M/-C, 2006-08-09).  The callers were in a pretty
confused state: some actually checked for the return code, and some
did not.

Let it return void, and patch all callers to take this into account.
This conveniently also gets rid of a handful of different(!) error
messages that could never be triggered anyway.

Note that the function can still die().

add416a6c0 checkout: don't confuse ref and object flags
When we are leaving a detached HEAD, we do a revision traversal to
check whether we are orphaning any commits, marking the commit we're
leaving as the start of the traversal, and all existing refs as
uninteresting.

Prior to commit 468224e5, we did so by calling for_each_ref, and
feeding each resulting refname to setup_revisions.  Commit 468224e5
refactored this to simply mark the pending objects, saving an extra
lookup.

However, it confused the "flags" parameter to the each_ref_fn
clalback, which is about the flags we found while looking up the ref
with the object flag.  Because REF_ISSYMREF ("this ref is a symbolic
ref, e.g. refs/remotes/origin/HEAD") happens to be the same bit
pattern as SEEN ("we have picked this object up from the pending
list and moved it to revs.commits list"), we incorrectly reported
that a commit previously at the detached HEAD will become
unreachable if the only ref that can reach the commit happens to be
pointed at by a symbolic ref.

b60e188c51 Strip namelen out of ce_flags into a ce_namelen field
Strip the name length from the ce_flags field and move it
into its own ce_namelen field in struct cache_entry. This
will both give us a tiny bit of a performance enhancement
when working with long pathnames and is a refactoring for
more readability of the code.

It enhances readability, by making it more clear what
is a flag, and where the length is stored and make it clear
which functions use stages in comparisions and which only
use the length.

It also makes CE_NAMEMASK private, so that users don't
mistakenly write the name length in the flags.

e9fc64c60a checkout: no progress messages if !isatty(2).
If stderr isn't a tty, we shouldn't be printing incremental progress
messages.  In particular, this affects 'git checkout -f . >&logfile'
unless you provided -q.  And git-new-workdir has no way to provide -q.

It would probably be better to have progress.c check isatty(2) all the time,
but that wouldn't allow things like 'git push --progress' to force progress
reporting to on, so I won't try to solve the general case right now.

Actual fix suggested by Jeff King.

8338f771fe checkout: do not corrupt HEAD on empty repo
In abe1998 ("git checkout -b: allow switching out of an unborn
branch"), a code-path overly-optimisticly assumed that a
branch-name was specified. This is not always the case, and as
a result a NULL-pointer was attempted printed to .git/HEAD.

This could lead to at least two different failure modes:
 1) vsnprintf formated the NULL-string as something useful (e.g
    "(null)")
 2) vsnprintf crashed

Neither were very convenient for formatting a new HEAD-reference.

To fix this, reintroduce some strictness so we only take this
new codepath if a banch-name was specified.

5d8863954f checkout (detached): truncate list of orphaned commits at the new HEAD

all orphaned commits were listed in a warning:

  Warning: you are leaving 2 commits behind...:

But if the new commit is actually one from this list (6aa1af6 in this
example), then the list in the warning can be truncated at the new HEAD,
because history beginning at HEAD is not "left behind". This makes it so.

d5a35c114a Copy resolve_ref() return value for longer use
resolve_ref() may return a pointer to a static buffer. Callers that
use this value longer than a couple of statements should copy the
value to avoid some hidden resolve_ref() call that may change the

The bug found by Tony Wang <wwwjfy@gmail.com> in builtin/merge.c
demonstrates this. The first call is in cmd_merge()

branch = resolve_ref("HEAD", head_sha1, 0, &flag);

Then deep in lookup_commit_or_die() a few lines after, resolve_ref()
may be called again and destroy "branch".

c1d7036b6b checkout,merge: disallow overwriting ignored files with --no-overwrite-ignore
Ignored files usually are generated files (e.g. .o files) and can be
safely discarded. However sometimes users may have important files in
working directory, but still want a clean "git status", so they mark
them as ignored files. But in this case, these files should not be
overwritten without asking first.

Enable this use case with --no-overwrite-ignore, where git only sees
tracked and untracked files, no ignored files. Those who mix
discardable ignored files with important ones may have to sort it out
themselves.

c689332391 Convert many resolve_ref() calls to read_ref*() and ref_exists()
resolve_ref() may return a pointer to a static buffer, which is not
safe for long-term use because if another resolve_ref() call happens,
the buffer may be changed.  Many call sites though do not care about
this buffer. They simply check if the return value is NULL or not.

Convert all these call sites to new wrappers to reduce resolve_ref()

to avoid passing static buffer out, this helps reduce changes.

8d9c50105f Change check_ref_format() to take a flags argument
Change check_ref_format() to take a flags argument that indicates what
is acceptable in the reference name (analogous to "git
check-ref-format"'s "--allow-onelevel" and "--refspec-pattern").  This
is more convenient for callers and also fixes a failure in the test
suite (and likely elsewhere in the code) by enabling "onelevel" and
"refspec-pattern" to be allowed independently of each other.

Also rename check_ref_format() to check_refname_format() to make it
obvious that it deals with refnames rather than references themselves.

We simply copy the struct object_array that points to the list, set

0a1283bc39 checkout $tree $path: do not clobber local changes in $path not in $tree
Checking paths out of a tree is (currently) defined to do:

 - Grab the paths from the named tree that match the given pathspec,
   and add them to the index;

 - Check out the contents from the index for paths that match the
   pathspec to the working tree; and while at it

 - If the given pathspec did not match anything, suspect a typo from the
   command line and error out without updating the index nor the working
   tree.

Suppose that the branch you are working on has dir/myfile, and the "other"
branch has dir/other but not dir/myfile. Further imagine that you have
either modified or removed dir/myfile in your working tree, but you have
not run "git add dir/myfile" or "git rm dir/myfile" to tell Git about your
local change. Running

 $ git checkout other dir

would add dir/other to the index with the contents taken out of the
"other" branch, and check out the paths from the index that match the
pathspec "dir", namely, "dir/other" and "dir/myfile", overwriting your
local changes to "dir/myfile", even though "other" branch does not even
know about that file.

Fix it by updating the working tree only with the index entries that
was read from the "other" tree.

fa79937675 branch --set-upstream: regression fix
The "git branch" command, while not in listing mode, calls create_branch()
even when the target branch already exists, and it does so even when it is
not interested in updating the value of the branch (i.e. the name of the
commit object that sits at the tip of the existing branch). This happens
when the command is run with "--set-upstream" option.

The earlier safety-measure to prevent "git branch -f $branch $commit" from
updating the currently checked out branch did not take it into account,
and we no longer can update the tracking information of the current branch.

Minimally fix this regression by telling the validation code if it is
called to really update the value of a potentially existing branch, or if
the caller merely is interested in updating auxiliary aspects of a branch.

55c4a67307 Prevent force-updating of the current branch
"git branch -M <foo> <current-branch>" allows updating the current branch
which HEAD points, without the necessary house-keeping that git reset
normally does to make this operation sensible. It also leaves the reflog
in a confusing state (you would be warned when trying to read it).

"git checkout -B <current branch> <foo>" is also partly vulnerable to this
bug; due to inconsistent pre-flight checks it would perform half of its
task and then abort just before rewriting the branch. Again this
manifested itself as the index file getting out-of-sync with HEAD.

"git branch -f" already guarded against this problem, and aborts with
a fatal error.

Update "git branch -M", "git checkout -B" and "git branch -f" to share the
same check before allowing a branch to be created. These prevent you from
updating the current branch.

We considered suggesting the use of "git reset" in the failure message
but concluded that it was not possible to discern what the user was
actually trying to do.

0f64bfa956 ls-files: fix pathspec display on error
The following sequence of commands reveals an issue with error
reporting of relative paths:

 $ mkdir sub
 $ cd sub
 $ git ls-files --error-unmatch ../bbbbb
 error: pathspec 'b' did not match any file(s) known to git.
 $ git commit --error-unmatch ../bbbbb
 error: pathspec 'b' did not match any file(s) known to git.

This bug is visible only if the normalized path (i.e., the relative
path from the repository root) is longer than the prefix.
Otherwise, the code skips over the normalized path and reads from
an unused memory location which still contains a leftover of the
original command line argument.

So instead, use the existing facilities to deal with relative paths
correctly.

Also fix inconsistency between "checkout" and "commit", e.g.

    $ cd Documentation
    $ git checkout nosuch.txt
    error: pathspec 'Documentation/nosuch.txt' did not match...
    $ git commit nosuch.txt
    error: pathspec 'nosuch.txt' did not match...

by propagating the prefix down the codepath that reports the error.

c17b229454 checkout -b <name>: correctly detect existing branch
When create a new branch, we fed "refs/heads/<proposed name>" as a string
to get_sha1() and expected it to fail when a branch already exists.

The right way to check if a ref exists is to check with resolve_ref().

A naïve solution that might appear attractive but does not work is to
forbid slashes in get_describe_name() but that will not work. A describe
name is is in the form of "ANYTHING-g<short sha1>", and that ANYTHING part
comes from a original tag name used in the repository the user ran the
describe command. A sick user could have a confusing hierarchical tag
whose name is "refs/heads/foobar" (stored as refs/tags/refs/heads/foobar")
to generate a describe name "refs/heads/foobar-6-g02ac983", and we should
be able to use that name to refer to the object whose name is 02ac983.

f807b3dcab checkout: make advice when reattaching the HEAD less loud
When switching away from a detached HEAD with "git checkout", we give a
listing of the commits about to be lost, and then tell how to resurrect
them since 8e2dc6a (commit: give final warning when reattaching HEAD to
leave commits behind, 2011-02-18).

This is a good safety measure for people who are not comfortable with the
detached HEAD state, but the advice on how to keep the state you just left
was given even to those who set advice.detachedHead to false.

Keep the warning and informational commit listing, but honor the setting
of advice.detachedHead to squelch the advice.

0be240cc65 checkout: tweak detached-orphan warning format
When orphaning a commit on a detached HEAD, the warning
currently looks like:

  Warning: you are leaving 3 commits behind, not connected to
  any of your branches:

   - commit subject 1
   - commit subject 2
   - commit subject 3

  If you want to keep them by creating a new branch, this
  may be a good time to do so with:

     git branch new_branch_name 933a615ab0bc566dcfd8c01ec8af159f770d3fe5

Instead of using the "-" list, let's provide a more
traditional oneline format, with the abbreviated sha1 before
each subject. Users are accustomed to seeing commits in this
format, and having the sha1 of each commit can be useful if
you want to cherry-pick instead of creating a new branch.

The new format looks like:

  Warning: you are leaving 3 commits behind, not connected to
  any of your branches:

    933a615 commit subject 1
    824fcde commit subject 2
    fa49b1a commit subject 3

8e2dc6ac06 commit: give final warning when reattaching HEAD to leave commits behind
You can detach the HEAD at an arbitrary commit in order to browse the
files in various points in the history or build older versions of the
software, without recording any new commit, and come back to an existing
branch.  When used in this "sightseer" mode, detached HEAD is a perfectly
safe mechanism.  It also is a useful state to experiment with throw-away
commits.

When coming back to an existing branch with "git checkout master",
however, the commits that were created on the detached HEAD will become
unreachable from anywhere but the reflog of the HEAD.  Check if the commit
we are about to leave is connected to some ref, and give a final warning
otherwise to remind the user for safety.

dab0d4108d correct type of EMPTY_TREE_SHA1_BIN
Functions such as hashcmp that expect a binary SHA-1 value take
parameters of type "unsigned char *" to avoid accepting a textual
SHA-1 passed by mistake.  Unfortunately, this means passing the string
literal EMPTY_TREE_SHA1_BIN requires an ugly cast.  Tweak the
definition of EMPTY_TREE_SHA1_BIN to produce a value of more
convenient type.

In the future the definition might change to

	extern const unsigned char empty_tree_sha1_bin[20];
	#define EMPTY_TREE_SHA1_BIN empty_tree_sha1_bin

f8bd36a433 checkout: rearrange update_refs_for_switch for clarity
Take care of simple, exceptional cases before the meat of the "check
out by branch name" code begins.  After this change, the function
vaguely follows the following pseudocode:

	if (-B or -b)
		create branch;
	if (plain "git checkout" or "git checkout HEAD")
		;
	else if (--detach or checking out by non-branch commit name)
		detach HEAD;
	else if (checking out by branch name)
		attach HEAD;

One nice side benefit is to make it possible to remove handling of
the --detach option from outside switch_branches.

32669671c7 checkout: introduce --detach synonym for "git checkout foo^{commit}"
For example, one might use this when making a temporary merge to
test that two topics work well together.

Patch by Junio, with tests from Jeff King.

[jn: with some extra checks for bogus commandline usage]

09ebad6fae checkout: split off a function to peel away branchname arg
The code to parse and consume the tree name and "--" in commands such
as "git checkout @{-1} -- '*.c'" is intimidatingly long.  Split it out
into a separate function and make it easier to skip on first reading
by making the data it uses and produces more explicit.

No functional change intended.

0cb6ad3c3d checkout: fix bug with ambiguous refs
The usual dwim_ref lookup prefers tags to branches. Because
checkout primarily works on branches, though, we switch that
behavior to prefer branches.

However, there was a bug in the implementation in which we
used lookup_commit_reference (which used the regular lookup
rules) to get the actual commit to checkout. Checking out an
ambiguous ref therefore ended up putting us in an extremely
broken state in which we wrote the branch ref into HEAD, but
actually checked out the tree for the tag.

This patch fixes the bug by always attempting to pull the
commit to be checked out from the branch-ified version of
the name we were given.

Patch by Junio, tests and commit message from Jeff King.

0e615b252f Replace "remote tracking" with "remote-tracking"
"remote-tracking" branch makes it explicit that the branch is "tracking a
remote", as opposed to "remote, and tracking something".

See discussion in e.g.
http://mid.gmane.org/8835ADF9-45E5-4A26-9F7F-A72ECC065BB2@gmail.com
for more details.

This patch is a straightforward application of

  perl -pi -e 's/remote tracking branch/remote-tracking branch/'

except in the RelNotes directory.
