Michael J Gruber 6e7293e3ed git-add: make -A description clearer vs. -u
Currently, it sounds as if "notice removal of files" distinguishes "-A"
from "-u", and there is no mention of the worktree.

But both notice the removal, and only "-A" adds changes from untracked
files. Say so.

Jonathan Nieder 2140b14064 commit: error out for missing commit message template
When "git commit" was rewritten in C (v1.5.4-rc0~78^2~30,
2007-11-08), a subtle bug in --template was introduced.  If the
file named by a --template parameter is missing, previously git
would error out with a message:

	Commit template file does not exist.

but in the C version the --template parameter gets ignored and
the default template is used.

t7500 has two tests for this case which would have caught it, except
that with the default $EDITOR, the commit message template is left
unmodified, causing 'git commit' to error out and the test to
succeed.

Junio C Hamano 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.

Libor Pechacek b09c53a3e3 Sanity-check config variable names
Sanity-check config variable names when adding and retrieving them.  As a side
effect code duplication between git_config_set_multivar and get_value (in
builtin/config.c) was removed and the common functionality was placed in
git_config_parse_key.

This breaks a test in t1300 which used invalid section-less keys in the tests
for "git -c". However, allowing such names there was useless, since there was
no way to set them via config file, and no part of git actually tried to use
section-less keys. This patch updates the test to use more realistic examples
as well as adding its own test.

Jay Soffian 37f7a85793 Teach commit about CHERRY_PICK_HEAD
Previously the user was advised to use commit -c CHERRY_PICK_HEAD after
a conflicting cherry-pick. While this would preserve the original
commit's authorship, it would sadly discard cherry-pick's carefully
crafted MERGE_MSG (which contains the list of conflicts as well as the
original commit-id in the case of cherry-pick -x).

On the other hand, if a bare 'commit' were performed, it would preserve
the MERGE_MSG while resetting the authorship.

In other words, there was no way to simultaneously take the authorship
from CHERRY_PICK_HEAD and the commit message from MERGE_MSG.

This change fixes that situation. A bare 'commit' will now take the
authorship from CHERRY_PICK_HEAD and the commit message from MERGE_MSG.
If the user wishes to reset authorship, that must now be done explicitly
via --reset-author.

A side-benefit of passing commit authorship along this way is that we
can eliminate redundant authorship parsing code from revert.c.

(Also removed an unused include from revert.c)

Jay Soffian d7e5c0cbfb Introduce CHERRY_PICK_HEAD
When a cherry-pick conflicts git advises:

 $ git commit -c <original commit id>

to preserve the original commit message and authorship. Instead, let's
record the original commit id in CHERRY_PICK_HEAD and advise:

  $ git commit -c CHERRY_PICK_HEAD

A later patch teaches git to handle the '-c CHERRY_PICK_HEAD' part.
Note that we record CHERRY_PICK_HEAD even in the case where there
are no conflicts so that we may use it to communicate authorship to
commit; this will then allow us to remove set_author_ident_env from
revert.c. However, we do not record CHERRY_PICK_HEAD when --no-commit
is used, as presumably the user intends to further edit the commit
and possibly even cherry-pick additional commits on top.

Jeff King 99bfc6691d merge: enable progress reporting for rename detection
The user can enable or disable it explicitly with the new
--progress, but it defaults to checking isatty(2).

This works only with merge-recursive and subtree. In theory
we could pass a progress flag to other strategies, but none

For its post-commit summary, commit was explicitly setting

it will fall back properly to the diff default, and that

Jeff King a902618792 clone: die when trying to clone missing local path
Since 86ac751 (Allow cloning an empty repository,
2009-01-23), doing:

  git clone does-not-exist

has created does-not-exist as an empty repository. This was
an unintentional side effect of 86ac751. Even weirder,
doing:

  git clone does-not-exist new-dir

_does_ fail, making this "feature" (if you want to consider
it such) broken. Let's detect this situation and explicitly
die. It's almost certainly not what the user intended.

This patch also adds two tests. One for the missing path
case, and one to confirm that a similar case, cloning a
non-repository directory, fails.

Martin von Zweigbergk ac49f5ca84 rerere "remaining"
After "rerere" resolves conflicts by reusing old resolution, there would
be three kinds of paths with conflict in the index:

 * paths that have been resolved in the working tree by rerere;
 * paths that need further work whose resolution could be recorded;
 * paths that need resolving that rerere won't help.

When the user wants a list of paths that need hand-resolving, output from
"rerere status" does not help, as it shows only the second category, but
the paths in the third category still needs work (rerere only makes sense
for regular files that have both our side and their side, and does not
help other kinds of conflicts, e.g. "we modified, they deleted").

The new subcommand "rerere remaining" can be used to show both. As
opposed to "rerere status", this subcommand also skips printing paths
that have been added to the index, since these paths are already
resolved and are no longer "remaining".

Initial patch provided by Junio. Refactored and modified to skip
resolved paths by Martin. Commit message mostly by Junio.

Johan Herland 53c403116a push.default: Rename 'tracking' to 'upstream'
Users are sometimes confused with two different types of "tracking" behavior
in Git: "remote-tracking" branches (e.g. refs/remotes/*/*) versus the
merge/rebase relationship between a local branch and its @{upstream}
(controlled by branch.foo.remote and branch.foo.merge config settings).

When the push.default is set to 'tracking', it specifies that a branch should
be pushed to its @{upstream} branch. In other words, setting push.default to
'tracking' applies only to the latter of the above two types of "tracking"
behavior.

In order to make this more understandable to the user, we rename the
push.default == 'tracking' option to push.default == 'upstream'.

push.default == 'tracking' is left as a deprecated synonym for 'upstream'.

Jonathan Nieder 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

		;
	else if (--detach or checking out by non-branch commit name)
		detach HEAD;

"git diff --cached" (without revision) used to mean "git diff --cached
HEAD" (i.e. the user was too lazy to type HEAD). This "correctly"

This patch changes the definition of what particular command means.
It is a request to show what _would_ be committed without further "git
add". The internal implementation is the same "git diff --cached HEAD"
when HEAD exists, but when there is no commit yet, it compares the index
with an empty tree object to achieve the desired result.

Junio C Hamano 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.

Jonathan Nieder 67ac1e1d57 cherry-pick/revert: add support for -X/--strategy-option
For example, this would allow cherry-picking or reverting patches from
a piece of history with a different end-of-line style, like so:

	$ git revert -Xrenormalize old-problematic-commit

Currently that is possible with manual use of merge-recursive but the
cherry-pick/revert porcelain does not expose the functionality.

While at it, document the existing support for --strategy.

Nguyễn Thái Ngọc Duy e6aea2dba2 setup: limit get_git_work_tree()'s to explicit setup case only
get_git_work_tree() takes input as core.worktree, core.bare,
GIT_WORK_TREE and decides correct worktree setting.

Unfortunately it does not do its job well. core.worktree and
GIT_WORK_TREE should only be taken into account, if GIT_DIR is set
(which is handled by setup_explicit_git_dir). For other setup cases,
only core.bare matters.

Add a temporary variable setup_explicit to adjust get_git_work_tree()
behavior as such. This variable will be gone once setup_* rework is
done.

Also remove is_bare_repository_cfg check in set_git_work_tree() to
ease the rework. We are going to check for core.bare and core.worktree
early before setting worktree. For example, if core.bare is true, no
need to set worktree.

Junio C Hamano 4c28e4ada0 commit: die before asking to edit the log message
When determine_author_info() returns to the calling prepare_to_commit(),
we already know the pieces of information necessary to determine what
author ident will be used in the final message, but deferred making a call
to fmt_ident() before the final commit_tree().  Most importantly, we would
open the editor to ask the user to compose the log message before it.

As one important side effect of fmt_ident() is to error out when the given
information is malformed, this resulted in us spawning the editor first
and then refusing to commit due to error, even though we had enough
information to detect the error before starting the editor, which was
annoying.

Move the fmt_ident() call to the end of determine_author_info() where we
have final determination of author info to rectify this.

Anders Kaseorg d1645d02de describe: Delay looking up commits until searching for an inexact match
Now that struct commit.util is not used until after we've checked that
the argument doesn't exactly match a tag, we can wait until then to
look up the commits for each tag.

This avoids a lot of I/O on --exact-match queries in repositories with
many tags.  For example, 'git describe --exact-match HEAD' becomes
about 12 times faster on a cold cache (3.2s instead of 39s) in a
linux-2.6 repository with 2000 packed tags.  That is a huge win for the
interactivity of the __git_ps1 shell prompt helper when on a detached
HEAD.

Anders Kaseorg 3cfa4db322 describe: Store commit_names in a hash table by commit SHA1
describe is currently forced to look up the commit at each tag in
order to store the struct commit_name pointers in struct commit.util.
For --exact-match queries, those lookups are wasteful.  In preparation
for removing them, put the commit_names into a hash table, indexed by
commit SHA1, that can be used to quickly check for exact matches.

Jonathan Nieder 309be813c9 update-index: migrate to parse-options API
--refresh and --really-refresh accept flags (like -q) and modify
an error indicator.  It might make sense to make the error
indicator global, but just pass the flags and a pointer to the error
indicator in a struct instead.

--cacheinfo wants 3 arguments.  Use the OPTION_LOWLEVEL_CALLBACK
extension to grab them and PARSE_OPT_NOARG to disallow the "sticked"
--cacheinfo=foo form.  (The resulting message

	$ git update-index --cacheinfo=foo
	error: option `cacheinfo' takes no value

is unfortunately incorrect.)

--assume-unchanged and --no-assume-unchanged probably should use the
OPT_UYN feature; but use a callback for now so the existing MARK_FLAG
and UNMARK_FLAG values can be used.

--stdin and --index-info are still constrained to be the last argument
(implemented using the OPTION_LOWLEVEL_CALLBACK extension).

--unresolve and --again consume all arguments that come after them
(also using OPTION_LOWLEVEL_CALLBACK).

The order of options matters.  Each path on the command line is
affected only by the options that come before it.  A custom
argument-parsing loop with parse_options_step() brings that about.

In exchange for all the fuss, we get the usual perks: support for
un-sticked options, better usage error messages, more useful -h
output, and argument parsing code that should be easier to tweak
in the future.
