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.

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.

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.

5e65ee35dd Move "show_all_errors = 1" to setup_unpack_trees_porcelain()
Not only this makes the code clearer since setting up the porcelain error
message is meant to work with show_all_errors, but this fixes a call to
setup_unpack_trees_porcelain() in git_merge_trees() which did not set
show_all_errors.

add_rejected_path() used to double-check whether it was running in
plumbing mode. This check was ineffective since it was setting
show_all_errors too late for traverse_trees() to see it, and is made
useless by this patch. Remove it.

175f6e59f6 checkout: respect diff.ignoreSubmodules setting
When 'git checkout' reports uncommitted changes, it also does so for
submodules.

The default mode is now to look really hard into submodules, not only
for different commits, but also for modified files. Since this can be
pretty expensive when there are a lot (and large) submodules, there is
the diff.ignoreSubmodules option.

Let's respect that setting when 'git checkout' reports the uncommitted
changes, since it does nothing else than a 'git diff --name-status'.

e6c111b4c0 unpack_trees: group error messages by type
When an error is encountered, it calls add_rejected_file() which either
- directly displays the error message and stops if in plumbing mode
  (i.e. if show_all_errors is not initialized at 1)
- or stores it so that it will be displayed at the end with display_error_msgs(),

Storing the files by error type permits to have a list of files for
which there is the same error instead of having a serie of almost
identical errors.

As each bind_overlap error combines a file and an old file, a list cannot be
done, therefore, theses errors are not stored but directly displayed.

23cbf11b5c merge-recursive: porcelain messages for checkout
A porcelain message was first added in checkout.c in the commit
8ccba008 (Junio C Hamano, Sat May 17 21:03:49 2008, unpack-trees:

in the case of merge errors.

This patch adapts the porcelain messages for the case of checkout
instead. This way, when having a checkout error, "merge" no longer
appears in the error message.

would_lose_untracked_file.

Teach "git merge-recursive" a --renormalize option to enable the

So in the future, you might be able to, e.g.:

	git checkout -m -Xrenormalize otherbranch

or

	git revert -Xrenormalize otherpatch

or

	git pull --rebase -Xrenormalize

The bad part: merge.renormalize is still not honored for most
commands.  And it reveals lots of places that -X has not been plumbed
in (so we get "git merge -Xrenormalize" but not much else).

the last declaration in the same block, in all the places necessary to

Similar to -b, --orphan creates a new branch, but it starts without any

new branch "newbranch", and the first commit you create from this state
will start a new history without any ancestry.

"git checkout --orphan" keeps the index and the working tree files
intact in order to make it convenient for creating a new history whose
trees resemble the ones from the original branch.

When creating a branch whose trees have no resemblance to the ones from
the original branch, it may be easier to start work on the new branch by
untracking and removing all working tree files that came from the
original branch, by running a 'git rm -rf .' immediately after running
"checkout --orphan".

c4151629e7 checkout -m --conflict=diff3: add a label for ancestor
git checkout --merge --conflict=diff3 can be used to present conflict
hunks including text from the common ancestor.  The added information
is helpful for resolving a merge by hand, and merge tools tend to
understand it because it is very similar to what ‘diff3 -m’ produces.

Unlike current git, diff3 -m includes a label for the merge base on
the ||||||| line, and unfortunately, some tools cannot parse the
conflict hunks without it.  Humans can benefit from a cue when
learning to interpreting the format, too.  Mark the start of the text
from the old branch with a label based on the branch’s name.

git rerere does not have trouble parsing this output and its preimage
ids are unchanged since it includes its own code for recreating
conflict hunks.  No other code in git tries to parse conflict hunks.

f0531a2937 checkout --conflict=diff3: add a label for ancestor
git checkout --conflict=diff3 can be used to present conflicts hunks
including text from the common ancestor:

	<<<<<<< ours
	ourside
	|||||||
	original
	=======
	theirside
	>>>>>>> theirs

The added information is helpful for resolving a merge by hand, and
merge tools can usually understand it without trouble because it looks
like output from ‘diff3 -m’.

diff3 includes a label for the merge base on the ||||||| line, and it
seems some tools (for example, Emacs 22’s smerge-mode) cannot parse
conflict hunks without such a label.  Humans could use help in
interpreting the output, too.  So change the marker for the start of the
text from the common ancestor to include the label “base”.

git rerere’s conflict identifiers are not affected: to parse conflict
hunks, rerere looks for whitespace after the ||||||| marker rather
than a newline, and to compute preimage ids, rerere has its own code
for creating conflict hunks.  No other code in git tries to parse
conflict hunks.

f01de62e45 ll_merge(): add ancestor label parameter for diff3-style output
Commands using the ll_merge() function will present conflict hunks
imitating ‘diff3 -m’ output if the merge.conflictstyle configuration
option is set appropriately.  Unlike ‘diff3 -m’, the output does not
include a label for the merge base on the ||||||| line of the output,
and some tools misparse the conflict hunks without that.

Add a new ancestor_label parameter to ll_merge() to give callers the
power to rectify this situation.  If ancestor_label is NULL, the output
format is unchanged.  All callers pass NULL for now.

81b50f3ce4 Move 'builtin-*' into a 'builtin/' subdirectory
This shrinks the top-level directory a bit, and makes it much more
pleasant to use auto-completion on the thing. Instead of

	[torvalds@nehalem git]$ em buil<tab>
	Display all 180 possibilities? (y or n)
	[torvalds@nehalem git]$ em builtin-sh
	builtin-shortlog.c     builtin-show-branch.c  builtin-show-ref.c
	builtin-shortlog.o     builtin-show-branch.o  builtin-show-ref.o
	[torvalds@nehalem git]$ em builtin-shor<tab>
	builtin-shortlog.c  builtin-shortlog.o
	[torvalds@nehalem git]$ em builtin-shortlog.c

you get

	[torvalds@nehalem git]$ em buil<tab>		[type]
	builtin/   builtin.h
	[torvalds@nehalem git]$ em builtin		[auto-completes to]
	[torvalds@nehalem git]$ em builtin/sh<tab>	[type]
	shortlog.c     shortlog.o     show-branch.c  show-branch.o  show-ref.c     show-ref.o
	[torvalds@nehalem git]$ em builtin/sho		[auto-completes to]
	[torvalds@nehalem git]$ em builtin/shor<tab>	[type]
	shortlog.c  shortlog.o
	[torvalds@nehalem git]$ em builtin/shortlog.c

which doesn't seem all that different, but not having that annoying
break in "Display all 180 possibilities?" is quite a relief.

NOTE! If you do this in a clean tree (no object files etc), or using an
editor that has auto-completion rules that ignores '*.o' files, you
won't see that annoying 'Display all 180 possibilities?' message - it
will just show the choices instead.  I think bash has some cut-off
around 100 choices or something.

So the reason I see this is that I'm using an odd editory, and thus
don't have the rules to cut down on auto-completion.  But you can
simulate that by using 'ls' instead, or something similar.
