69c61c4fa9 git add: add long equivalents of '-u' and '-f' options
The option -u stands for --update and it is a good idea to make it clear
especially because this is the only mode of operation of "git add" that
does something different from "adding".  Give longer --force synonym to -f
while we are at it as well.

205ffa94be Make git add -n and git -u -n output consistent
Output format from "git add -n $path" lists path to blobs that are going
to be added on a single line, separated with SP.  On the other hand, the
suggested "git add -u -n" shows one path per line, like "add '<file>'\n".
Of course, these two are inconsistent.

Plain "git add -n" can afford to only say names of paths, as all it does
is to add (update).  However, "git add -u" needs to be able to express
"remove" somehow.  So if we need to have them formatted the same way, we
need to unify with the "git add -n -u" format.  Incidentally, this is
consistent with how 'update-index' says it.

This changes the output from "git add -n $paths" but as a general
principle, output from Porcelain commands is a fair game for improvements
and not for script consumption.

6c53e7ac04 Revert part of 1abf095 (git-add: adjust to the get_pathspec() changes)
When get_pathspec() was originally made absolute-path capable,
we botched the interface to it, without dying inside the function
when given a path that is outside the work tree, and made it the
responsibility of callers to check the condition in a roundabout
way.  This is made unnecessary with the previous patch.

Earlier get_pathspec() returned all the inputs including bad ones, but
the new one issues warnings and removes offending ones from its return
value, so the callers need to be adjusted to notice it.

b63e995001 Add "--patch" option to git-add--interactive
When the "--patch" option is supplied, the patch_update_cmd() function is
called bypassing the main_loop() and exits.

Seeing as builtin-add is the only caller of git-add--interactive we can
impose a strict requirement on the format of the arguments to avoid
possible ambiguity: an "--" argument must be used whenever any pathspecs
are passed, both with the "--patch" option and without it.

3f061887c5 add -i: Fix running from a subdirectory
This fixes the pathspec interactive_add() passes to the underlying
git-add--interactive helper.  When the command was run from a
subdirectory, cmd_add() already has gone up to the toplevel of the work
tree, and the helper will be spawned from there.  The pathspec given on
the command line from the user needs to be adjusted for this.

This adds "validate_pathspec()" function in the callchain, but it does
not validate yet.  The function can be changed to barf if there are
unmatching pathspec given by the user, but that is not strictly
necessary.

039bc64e88 core.excludesfile clean-up
There are inconsistencies in the way commands currently handle
the core.excludesfile configuration variable.  The problem is
the variable is too new to be noticed by anything other than
git-add and git-status.

 * git-ls-files does not notice any of the "ignore" files by
   default, as it predates the standardized set of ignore files.
   The calling scripts established the convention to use
   .git/info/exclude, .gitignore, and later core.excludesfile.

 * git-add and git-status know about it because they call
   add_excludes_from_file() directly with their own notion of
   which standard set of ignore files to use.  This is just a
   stupid duplication of code that need to be updated every time
   the definition of the standard set of ignore files is
   changed.

 * git-read-tree takes --exclude-per-directory=<gitignore>,
   not because the flexibility was needed.  Again, this was
   because the option predates the standardization of the ignore
   files.

 * git-merge-recursive uses hardcoded per-directory .gitignore
   and nothing else.  git-clean (scripted version) does not
   honor core.* because its call to underlying ls-files does not
   know about it.  git-clean in C (parked in 'pu') doesn't either.

We probably could change git-ls-files to use the standard set
when no excludes are specified on the command line and ignore
processing was asked, or something like that, but that will be a
change in semantics and might break people's scripts in a subtle
way.  I am somewhat reluctant to make such a change.

On the other hand, I think it makes perfect sense to fix
git-read-tree, git-merge-recursive and git-clean to follow the
same rule as other commands.  I do not think of a valid use case
to give an exclude-per-directory that is nonstandard to
read-tree command, outside a "negative" test in the t1004 test
script.

This patch is the first step to untangle this mess.

The next step would be to teach read-tree, merge-recursive and
clean (in C) to use setup_standard_excludes().

fb63d7f889 git-add: make the entry stat-clean after re-adding the same contents
Earlier in commit 0781b8a9b2
(add_file_to_index: skip rehashing if the cached stat already
matches), add_file_to_index() were taught not to re-add the path
if it already matches the index.

The change meant well, but was not executed quite right.  It
used ie_modified() to see if the file on the work tree is really
different from the index, and skipped adding the contents if the
function says "not modified".

This was wrong.  There are three possible comparison results
between the index and the file in the work tree:

 - with lstat(2) we _know_ they are different.  E.g. if the
   length or the owner in the cached stat information is
   different from the length we just obtained from lstat(2), we
   can tell the file is modified without looking at the actual
   contents.

 - with lstat(2) we _know_ they are the same.  The same length,
   the same owner, the same everything (but this has a twist, as
   described below).

 - we cannot tell from lstat(2) information alone and need to go
   to the filesystem to actually compare.

The last case arises from what we call 'racy git' situation,
that can be caused with this sequence:

    $ echo hello >file
    $ git add file
    $ echo aeiou >file ;# the same length

If the second "echo" is done within the same filesystem
timestamp granularity as the first "echo", then the timestamp
recorded by "git add" and the timestamp we get from lstat(2)
will be the same, and we can mistakenly say the file is not
modified.  The path is called 'racily clean'.  We need to
reliably detect racily clean paths are in fact modified.

To solve this problem, when we write out the index, we mark the
index entry that has the same timestamp as the index file itself
(that is the time from the point of view of the filesystem) to
tell any later code that does the lstat(2) comparison not to
trust the cached stat info, and ie_modified() then actually goes
to the filesystem to compare the contents for such a path.

That's all good, but it should not be used for this "git add"
optimization, as the goal of "git add" is to actually update the
path in the index and make it stat-clean.  With the false
optimization, we did _not_ cause any data loss (after all, what
we failed to do was only to update the cached stat information),
but it made the following sequence leave the file stat dirty:

    $ echo hello >file
    $ git add file
    $ echo hello >file ;# the same contents
    $ git add file

The solution is not to use ie_modified() which goes to the
filesystem to see if it is really clean, but instead use
ie_match_stat() with "assume racily clean paths are dirty"
option, to force re-adding of such a path.

There was another problem with "git add -u".  The codepath
shares the same issue when adding the paths that are found to be
modified, but in addition, it asked "git diff-files" machinery
run_diff_files() function (which is "git diff-files") to list
the paths that are modified.  But "git diff-files" machinery
uses the same ie_modified() call so that it does not report
racily clean _and_ actually clean paths as modified, which is
not what we want.

The patch allows the callers of run_diff_files() to pass the
same "assume racily clean paths are dirty" option, and makes
"git-add -u" codepath to use that option, to discover and re-add
racily clean _and_ actually clean paths.

We could further optimize on top of this patch to differentiate
the case where the path really needs re-adding (i.e. the content
of the racily clean entry was indeed different) and the case
where only the cached stat information needs to be refreshed
(i.e. the racily clean entry was actually clean), but I do not
think it is worth it.

This patch applies to maint and all the way up.

09d5dc32fb Simplify cache API
Earlier, add_file_to_index() invalidated the path in the cache-tree
but remove_file_from_cache() did not, and the user of the latter
needed to invalidate the entry himself.  This led to a few bugs due to
missed invalidate calls already.  This patch makes the management of
cache-tree less error prone by making more invalidate calls from lower
level cache API functions.

The rules are:

 - If you are going to write the index, you should either maintain
   cache_tree correctly.

   - If you cannot, alternatively you can remove the entire cache_tree
     by calling cache_tree_free() before you call write_cache().

   - When you modify the index, cache_tree_invalidate_path() should be
     called with the path you are modifying, to discard the entry from
     the cache-tree structure.

 - The following cache API functions exported from read-cache.c (and
   the macro whose names have "cache" instead of "index")
   automatically call cache_tree_invalidate_path() for you:

   - remove_file_from_index();
   - add_file_to_index();
   - add_index_entry();

   You can modify the index bypassing the above API functions
   (e.g. find an existing cache entry from the index and modify it in
   place).  You need to call cache_tree_invalidate_path() yourself in
   such a case.

e96980ef81 builtin-add: simplify (and increase accuracy of) exclude handling
Previously, the code would always set up the excludes, and then manually
pick through the pathspec we were given, assuming that non-added but
existing paths were just ignored. This was mostly correct, but would
erroneously mark a totally empty directory as 'ignored'.

Instead, we now use the collect_ignored option of dir_struct, which
unambiguously tells us whether a path was ignored. This simplifies the
code, and means empty directories are now just not mentioned at all.

Furthermore, we now conditionally ask dir_struct to respect excludes,
depending on whether the '-f' flag has been set. This means we don't have
to pick through the result, checking for an 'ignored' flag; ignored entries
were either added or not in the first place.

We can safely get rid of the special 'ignored' flags to dir_entry, which
were not used anywhere else.

93c44d493b git-add: allow path limiting with -u
Rather than updating all working tree paths, we limit
ourselves to paths listed on the command line.

dfdac5d9b8 git-add -u: match the index with working tree.
This is a shorthand of what "git commit -a" does in preparation
for making a commit, which is:

    git diff-files --name-only -z | git update-index --remove -z --stdin

fd1c3bf053 Rename add_file_to_index() to add_file_to_cache()
This function was not called "add_file_to_cache()" only because
an ancient program, update-cache, used that name as an internal
function name that does something slightly different.  Now that
is gone, we can take over the better name.

The plan is to name all functions that operate on the default
index xxx_cache().  Later patches create a variant of them that
take an explicit parameter xxx_index(), and then turn
xxx_cache() functions into macros that use "the_index".

30ca07a249 _GIT_INDEX_OUTPUT: allow plumbing to output to an alternative index file.
When defined, this allows plumbing commands that update the
index (add, apply, checkout-index, merge-recursive, mv,
read-tree, rm, update-index, and write-tree) to write their
resulting index to an alternative index file while holding a
lock to the original index file.  With this, git-commit that
jumps the index does not have to make an extra copy of the index
file, and more importantly, it can do the update while holding
the lock on the index.

However, I think the interface to let an environment variable
specify the output is a mistake, as shown in the documentation.
If a curious user has the environment variable set to something
other than the file GIT_INDEX_FILE points at, almost everything
will break.  This should instead be a command line parameter to
tell these plumbing commands to write the result in the named
file, to prevent stupid mistakes.

9fc42d6091 Optimize directory listing with pathspec limiter.
The way things are set up, you can now pass a "pathspec" to the
"read_directory()" function. If you pass NULL, it acts exactly
like it used to do (read everything). If you pass a non-NULL
pointer, it will simplify it into a "these are the prefixes
without any special characters", and stop any readdir() early if
the path in question doesn't match any of the prefixes.

NOTE! This does *not* obviate the need for the caller to do the *exact*
pathspec match later. It's a first-level filter on "read_directory()", but
it does not do the full pathspec thing. Maybe it should. But in the
meantime, builtin-add.c really does need to do first

	read_directory(dir, .., pathspec);
	if (pathspec)
		prune_directory(dir, pathspec, baselen);

ie the "prune_directory()" part will do the *exact* pathspec pruning,
while the "read_directory()" will use the pathspec just to do some quick
high-level pruning of the directories it will recurse into.

896bdfa258 add: Support specifying an excludes file with a configuration variable
This adds the 'core.excludesfile' configuration variable. This variable can
hold a path to a file containing patterns of file names to exclude from
git-add, like $GIT_DIR/info/exclude. Patterns in the excludes file are used
in addition to those in info/exclude.

4d06f8ac43 Fix 'git add' with .gitignore
When '*.ig' is ignored, and you have two files f.ig and d.ig/foo
in the working tree,

	$ git add .

correctly ignored f.ig but failed to ignore d.ig/foo.  This was
caused by a thinko in an earlier commit 4888c534, when we tried
to allow adding otherwise ignored files.

After reverting that commit, this takes a much simpler approach.
When we have an unmatched pathspec that talks about an existing
pathname, we know it is an ignored path the user tried to add,
so we include it in the set of paths directory walker returned.

This does not let you say "git add -f D" on an ignored directory
D and add everything under D.  People can submit a patch to
further allow it if they want to, but I think it is a saner
behaviour to require explicit paths to be spelled out in such a
case.
