Untracked directories with .git should be ignored
This restores a behavior that was accidentally lost during some
diff refactoring where an untracked directory that contains a .git
item should be treated as IGNORED, not as UNTRACKED. The submodule
code already detects this, but the diff code was not handling the
scenario right.
This also updates a number of existing tests that were actually
exercising the behavior but did not have the right expectations in
place. It actually makes the new
`test_diff_submodules__diff_ignore_options` test feel much better
because the "not-a-submodule" entries are now ignored instead of
showing up as untracked items.
Fixes #1697

Add ignore_submodules to diff options
This adds correct support for an equivalent to --ignore-submodules
in diff, where an actual ignore value can be passed to diff to
override the per submodule settings in the configuration.
This required tweaking the constants for ignore values so that
zero would not be used and could represent an unset option to the
diff. This was an opportunity to move the submodule values into
include/git2/types.h and to rename the poorly named DEFAULT values
for ignore and update constants to RESET instead.
Now the GIT_DIFF_IGNORE_SUBMODULES flag is exactly the same as
setting the ignore_submodules option to GIT_SUBMODULE_IGNORE_ALL
(which is actually a minor change from the old behavior in that
submodules will now be treated as UNMODIFIED deltas instead of
being left out totally - if you set GIT_DIFF_INCLUDE_UNMODIFIED).
This includes tests for the various new settings.

Update diff to new internal submodule status API
Submodules now expose an internal status API that allows diff to
get back the OID values from the submodule very easily and also
to avoiding caching issues and to override the ignore setting for
the submodule.

Add git_pathspec_match_diff API
This adds an additional pathspec API that will match a pathspec
against a diff object. This is convenient if you want to handle
renames (so you need the whole diff and can't use the pathspec
constraint built into the diff API) but still want to tell if the
diff had any files that matched the pathspec.
When the pathspec is matched against a diff, instead of keeping
a list of filenames that matched, instead the API keeps the list
of git_diff_deltas that matched and they can be retrieved via a
new API git_pathspec_match_list_diff_entry.
There are a couple of other minor API extensions here that were
mostly for the sake of convenience and to reduce dependencies
on knowing the internal data structure between files inside the
library.

Add public API for pathspec matching
This adds a new public API for compiling pathspecs and matching
them against the working directory, the index, or a tree from the
repository. This also reworks the pathspec internals to allow the
sharing of code between the existing internal usage of pathspec
matching and the new external API.
While this is working and the new API is ready for discussion, I
think there is still an incorrect behavior in which patterns are
always matched against the full path of an entry without taking
the subdirectories into account (so "s*" will match "subdir/file"
even though it wouldn't with core Git). Further enhancements are
coming, but this was a good place to take a functional snapshot.

Add status flags to force output sort order
Files in status will, be default, be sorted according to the case
insensitivity of the filesystem that we're running on. However,
in some cases, this is not desirable. Even on case insensitive
file systems, 'git status' at the command line will generally use
a case sensitive sort (like 'ls'). Some GUIs prefer to display a
list of file case insensitively even on case-sensitive platforms.
This adds two new flags: GIT_STATUS_OPT_SORT_CASE_SENSITIVELY
and GIT_STATUS_OPT_SORT_CASE_INSENSITIVELY that will override the
default sort order of the status output and give the user control.
This includes tests for exercising these new options and makes
the examples/status.c program emulate core Git and always use a
case sensitive sort.

Add index pathspec-based operations
This adds three new public APIs for manipulating the index:
1. `git_index_add_all` is similar to `git add -A` and will add
files in the working directory that match a pathspec to the
index while honoring ignores, etc.
2. `git_index_remove_all` removes files from the index that match
a pathspec.
3. `git_index_update_all` updates entries in the index based on
the current contents of the working directory, either added
the new information or removing the entry from the index.

Always do tree to index diffs case sensitively
Trees are always case sensitive. The index is always case
preserving and will be case sensitive when it is turned into a
tree. Therefore the tree and the index can and should always
be compared to one another case sensitively.
This will restore the index to case insensitive order after the
diff has been generated.
Consider this a short-term fix. The long term fix is to have the
index always stored both case sensitively and case insensitively
(at least on platforms that sometimes require case insensitivity).

Improve case handling in git_diff__paired_foreach
This commit reinstates some changes to git_diff__paired_foreach
that were discarded during the rebase (because the diff_output.c
file had gone away), and also adjusts the case insensitively
logic slightly to hopefully deal with either mismatched icase
diffs and other case insensitivity scenarios.

Be more careful about the path with diffs
This makes diff more careful about picking the canonical path
when generating a delta so that it won't accidentally pick up a
case-mismatched path on a case-insensitive file system. This
should make sure we use the "most accurate" case correct version
of the path (i.e. from the tree if possible, or the index if
need be).

Reorganize diff and add basic diff driver
This is a significant reorganization of the diff code to break it
into a set of more clearly distinct files and to document the new
organization. Hopefully this will make the diff code easier to
understand and to extend.
This adds a new `git_diff_driver` object that looks of diff driver
information from the attributes and the config so that things like
function content in diff headers can be provided. The full driver
spec is not implemented in the commit - this is focused on the
reorganization of the code and putting the driver hooks in place.
This also removes a few #includes from src/repository.h that were
overbroad, but as a result required extra #includes in a variety
of places since including src/repository.h no longer results in
pulling in the whole world.

errors in their object management code.

Make iterators use GIT_ITEROVER & smart advance
1. internal iterators now return GIT_ITEROVER when you go past the
last item in the iteration.
2. git_iterator_advance will "advance" to the first item in the
iteration if it is called immediately after creating the
iterator, which allows a simpler idiom for basic iteration.
3. if git_iterator_advance encounters an error reading data (e.g.
a missing tree or an unreadable file), it returns the error
but also attempts to advance past the invalid data to prevent
an infinite loop.
Updated all tests and internal usage of iterators to account for
these new behaviors.

Add GIT_DIFF_LINE_CONTEXT_EOFNL
This adds a new line origin constant for the special line that
is used when both files end without a newline.
In the course of writing the tests for this, I was having problems
with modifying a file but not having diff notice because it was
the same size and modified less than one second from the start of
the test, so I decided to start working on nanosecond timestamp
support. This commit doesn't contain the nanosecond support, but
it contains the reorganization of maybe_modified and the hooks so
that if the nanosecond data were being read by stat() (or rather
being copied by git_index_entry__init_from_stat), then the nsec
would be taken into account.
This new stuff could probably use some more tests, although there
is some amount of it here.

Update diff handling of untracked directories
When diff encounters an untracked directory, there was a shortcut
that it took which is not compatible with core git. This makes
the default behavior no longer take that shortcut and instead look
inside the untracked directory to see if there are any untracked
files within it. If there are not, then the directory is treated
as an ignore directory instead of an untracked directory. This
has implications for the git_status APIs.

Reorganize diff code into functions
In preparation for more changes to the internal diff logic, it
seemed wise to split the very large git_diff__from_iterators into
separate functions that handle the four main cases (unmatched old
item, unmatched new item, unmatched new directory, and matched
old and new items). Hopefully this will keep the logic easier to
follow even as more cases have to be added to this code.

Improve diff config options handling
This makes diff use the cvar cache for config options where
possible, and also adds support for a number of other config
options to diff including "diff.context", "diff.ignoreSubmodules",
"diff.noprefix", "diff.mnemonicprefix", and "core.abbrev".
To make this natural, this involved a rearrangement of the code
that allocates the diff object vs. the code that initializes it
based on the combination of options passed in by the user and
read from the config.
This commit includes tests for most of these new options as well.

Make tree to tree diffs case sensitive
When case insensitive tree iterators were added, we started reading
the case sensitivity of the index to decide if the tree should be
case sensitive. This is good for index-to-tree comparisons, but
for tree-to-tree comparisons, we should really default to doing a
case sensitive comparison unless the user really wants otherwise.

Tests and more fixes for submodule diffs
This adds tests for diffs with submodules in them and (perhaps
unsurprisingly) requires further fixes to be made. Specifically,
this fixes:
- when considering if a submodule is dirty in the workdir, it was
being treated as dirty even if only the index was dirty.
- git_diff_patch_to_str (and git_diff_patch_print) were "printing"
the headers for files (and submodules) that were unmodified or
had no meaningful content.
- added comment to previous fix and removed unneeded parens.

Fix some diff ignores and submodule dirty workdir
This started out trying to look at the problems from issue #1425
and gradually grew to a broader set of fixes. There are two core
things fixed here:
1. When you had an ignore like "/bin" which is rooted at the top
of your tree, instead of immediately adding the "bin/" entry
as an ignored item in the diff, we were returning all of the
direct descendants of the directory as ignored items. This
changes things to immediately ignore the directory. Note that
this effects the behavior in test_status_ignore__subdirectories
so that we no longer exactly match core gits ignore behavior,
but the new behavior probably makes more sense (i.e. we now
will include an ignored directory inside an untracked directory
that we previously would have left off).
2. When a submodule only contained working directory changes, the
diff code was always considering it unmodified which was just
an outright bug. The HEAD SHA of the submodule matches the SHA
in the parent repo index, and since the SHAs matches, the diff
code was overwriting the actual status with UNMODIFIED.
These fixes broke existing tests test_diff_workdir__submodules and
test_status_ignore__subdirectories but looking it over, I actually
think the new results are correct and the old results were wrong.
@nulltoken had actually commented on the subdirectory ignore issue
previously.
I also included in the tests some debugging versions of the
shared iteration callback routines that print status or diff
information. These aren't used actively in the tests, but can be
quickly swapped in to test code to give a better picture of what
is being scanned in some of the complex test scenarios.

Implement GIT_STATUS_OPT_EXCLUDE_SUBMODULES
This option has been sitting unimplemented for a while, so I
finally went through and implemented it along with some tests.
As part of this, I improved the implementation of

extra work and about leaving off delta records for submodules to
the greatest extent possible (though it may include them still
if you are request TYPECHANGE records).

Three submodule status bug fixes
1. Fix sort order problem with submodules where "mod" was sorting
after "mod-plus" because they were being sorted as "mod/" and
"mod-plus/". This involved pushing the "contains a .git entry"
test significantly lower in the stack.
2. Reinstate behavior that a directory which contains a .git entry
will be treated as a submodule during iteration even if it is
not yet added to the .gitmodules.
3. Now that any directory containing .git is reported as submodule,
we have to be more careful checking for GIT_EEXISTS when we
do a submodule lookup, because that is the error code that is
returned by git_submodule_lookup when you try to look up a
directory containing .git that has no record in gitmodules or
the index.

Add INCLUDE_TREES, DONT_AUTOEXPAND iterator flags
This standardizes iterator behavior across all three iterators
(index, tree, and working directory). Previously the working
directory iterator behaved differently from the other two.
Each iterator can now operate in one of three modes:
1. *No tree results, auto expand trees* means that only non-
tree items will be returned and when a tree/directory is
encountered, we will automatically descend into it.
2. *Tree results, auto expand trees* means that results will
be given for every item found, including trees, but you
only need to call normal git_iterator_advance to yield
every item (i.e. trees returned with pre-order iteration).
3. *Tree results, no auto expand* means that calling the
normal git_iterator_advance when looking at a tree will
not descend into the tree, but will skip over it to the
next entry in the parent.
Previously, behavior 1 was the only option for index and tree
iterators, and behavior 3 was the only option for workdir.
The main public API implications of this are that the
`git_iterator_advance_into()` call is now valid for all
iterators, not just working directory iterators, and all the
existing uses of working directory iterators explicitly use
the GIT_ITERATOR_DONT_AUTOEXPAND (for now).
Interestingly, the majority of the implementation was in the
index iterator, since there are no tree entries there and now
have to fake them. The tree and working directory iterators
only required small modifications.

Make iterator APIs consistent with standards
The iterator APIs are not currently consistent with the parameter
ordering of the rest of the codebase. This rearranges the order
of parameters, simplifies the naming of a number of functions, and
makes somewhat better use of macros internally to clean up the
iterator code.
This also expands the test coverage of iterator functionality,
making sure that case sensitive range-limited iteration works
correctly.

Replace diff delta binary with flags
Previously the git_diff_delta recorded if the delta was binary.
This replaces that (with no net change in structure size) with
a full set of flags. The flag values that were already in use
for individual git_diff_file objects are reused for the delta
flags, too (along with renaming those flags to make it clear that
they are used more generally).
This (a) makes things somewhat more consistent (because I was
using a -1 value in the "boolean" binary field to indicate unset,
whereas now I can just use the flags that are easier to understand),
and (b) will make it easier for me to add some additional flags to
the delta object in the future, such as marking the results of a
copy/rename detection or other deltas that might want a special
indicator.
While making this change, I officially moved some of the flags that
were internal only into the private diff header.
This also allowed me to remove a gross hack in rename/copy detect
code where I was overwriting the status field with an internal
value.

diff: add a notify callback to `git_diff__from_iterators`
The callback will be called for each file, just before the `git_delta_t` gets inserted into the diff list.
When the callback:

- returns > 0, the delta will not be inserted into the diff list, but the diff process continues
- returns 0, the delta is inserted into the diff list, and the diff process continues

that case there is no matched pattern per se.

Update iterator API with flags for ignore_case
This changes the iterator API so that flags can be passed in to
the constructor functions to control the ignore_case behavior.
At this point, the flags are not supported on tree iterators (i.e.
there is no functional change over the old API), but the API
changes are all made to accomodate this.
By the way, I went with a flags parameter because in the future
I have a couple of other ideas for iterator flags that will make
it easier to fix some diff/status/checkout bugs.

Make spoolandsort a pushable iterator behavior
An earlier change to `git_diff_from_iterators` introduced a
memory leak where the allocated spoolandsort iterator was not
returned to the caller and thus not freed.
One proposal changes all iterator APIs to use git_iterator** so
we can reallocate the iterator at will, but that seems unexpected.
This commit makes it so that an iterator can be changed in place.
The callbacks are isolated in a separate structure and a pointer
to that structure can be reassigned by the spoolandsort extension.
This means that spoolandsort doesn't create a new iterator; it
just allocates a new block of callbacks (along with space for its
own extra data) and swaps that into the iterator.
Additionally, since spoolandsort is only needed to switch the
case sensitivity of an iterator, this simplifies the API to only
take the ignore_case boolean and to be a no-op if the iterator
already matches the requested case sensitivity.

Fix diff constructor name order confusion
The diff constructor functions had some confusing names, where the
"old" side of the diff was coming after the "new" side. This
reverses the order in the function name to make it less confusing.
Specifically...
* git_diff_index_to_tree becomes git_diff_tree_to_index
* git_diff_workdir_to_index becomes git_diff_index_to_workdir
* git_diff_workdir_to_tree becomes git_diff_tree_to_workdir

Clean up iterator APIs
This removes the need to explicitly pass the repo into iterators
where the repo is implied by the other parameters. This moves
the repo to be owned by the parent struct. Also, this has some
iterator related updates to the internal diff API to lay the
groundwork for checkout improvements.

Add explicit git_index ptr to diff and checkout
A number of diff APIs and the `git_checkout_index` API take a
`git_repository` object an operate on the index. This updates
them to take a `git_index` pointer explicitly and only fall back
on the `git_repository` index if the index input is NULL. This
makes it easier to operate on a temporary index.

Some diff refactorings to help code reuse
There are some diff functions that are useful in a rewritten
checkout and this lays some groundwork for that. This contains
three main things:
1. Share the function diff uses to calculate the OID for a file
in the working directory (now named `git_diff__oid_for_file`
2. Add a `git_diff__paired_foreach` function to iterator over
two diff lists concurrently. Convert status to use it.
3. Move all the string/prefix/index entry comparisons into
function pointers inside the `git_diff_list` object so they
can be switched between case sensitive and insensitive
versions. This makes them easier to reuse in various
functions without replicating logic. As part of this, move
a couple of index functions out of diff.c and into index.c.

Move pathspec code in separate files
Diff uses a `git_strarray` of path specs to represent a subset
of all files to be processed. It is useful to be able to reuse
this filtering in other places outside diff, so I've moved it
into a standalone set of utilities.

Move rename detection into new file
This improves the naming for the rename related functionality
moving it to be called `git_diff_find_similar()` and renaming
all the associated constants, etc. to make more sense.
I also moved the new code (plus the existing `git_diff_merge`)
into a new file `diff_tform.c` where I can put new functions
related to manipulating git diff lists.
This also updates the implementation significantly from the
last revision fixing some ordering issues (where break-rewrite
needs to be handled prior to copy and rename detection) and
improving config option handling.

Initial implementation of diff rename detection
This implements the basis for diff rename and copy detection,
although it is based on simple SHA comparison right now instead
of using a matching algortihm. Just as `git_diff_merge` can be
used as a post-pass on diffs to emulate certain command line
behaviors, there is a new API `git_diff_detect` which will
update a diff list in-place, adjusting some deltas to RENAMED
or COPIED state (and also, eventually, splitting MODIFIED deltas
where the change is too large into DELETED/ADDED pairs).
This also adds a new test repo that will hold rename/copy/split
scenarios. Right now, it just has exact-match rename and copy,
but the tests are written to use tree diffs, so we should be able
to add new test scenarios easily without breaking tests.

Add complex checkout test and then fix checkout
This started as a complex new test for checkout going through the
"typechanges" test repository, but that revealed numerous issues
with checkout, including:
* complete failure with submodules
* failure to create blobs with exec bits
* problems when replacing a tree with a blob because the tree
"example/" sorts after the blob "example" so the delete was
being processed after the single file blob was created
This fixes most of those problems and includes a number of other
minor changes that made it easier to do that, including improving
the TYPECHANGE support in diff/status, etc.

Introduce status/diff TYPECHANGE flags
When I wrote the diff code, I based it on core git's diff output
which tends to split a type change into an add and a delete. But
core git's status has the notion of a T (typechange) flag for a
file. This introduces that into our status APIs and modifies the
diff code so it can be forced to not split type changes.

Add test for diffs with submodules and bug fixes
The adds a test for the submodule diff capabilities and then

the accuracy of OIDs in the diff delta object and makes the
submodule output more closely mirror the OIDs that will be used
by core git.

Fix a few diff bugs with directory content
There are a few cases where diff should leave directories in
the diff list if we want to match core git, such as when the
directory contains a .git dir. That feature was lost when I
introduced some of the new submodule handling.
This restores that and then fixes a couple of related to diff
output that are triggered by having diffs with directories in
them.
Also, this adds a new flag that can be passed to diff if you
want diff output to actually include the file content of any
untracked files.

Diff: Do not try to calculate an oid for a GITLINK.
We don't have anything useful that we could do with that oid anyway (We
need to query the submodule for the HEAD commit instead).
Without this, the following code creates the error "Failed to read
descriptor: Is a directory" when run against the submod2 test-case:
const char* oidstr = "873585b94bdeabccea991ea5e3ec1a277895b698";
git_tree* tree = resolve_commit_oid_to_tree(g_repo, oidstr);
git_diff_list* diff = NULL;
cl_assert(tree);
cl_git_pass(git_diff_workdir_to_tree(g_repo, NULL, tree, &diff));

Diff: teach get_workdir_content to show a submodule as text
1. teach diff.c:maybe_modified to query git_submodule_status for the
modification state of a submodule. According to the
git_submodule_status docs, it will filter for to-ignore states
already.
2. teach diff_output.c:get_workdir_content to check the submodule status
again and create a line like:
Subproject commit <SHA-1>\n
or
Subproject comimt <SHA-1>-dirty\n
like git.git does.

Add const to all shared pointers in diff API
There are a lot of places where the diff API gives the user access
to internal data structures and many of these were being exposed
through non-const pointers. This replaces them all with const
pointers for any object that the user can access but is still
owned internally to the git_diff_list or git_diff_patch objects.
This will probably break some bindings... Sorry!

Fix bugs in new diff patch code
This fixes all the bugs in the new diff patch code. The only
really interesting one is that when we merge two diffs, we now
have to actually exclude diff delta records that are not supposed
to be tracked, as opposed to before where they could be included
because they would be skipped silently by `git_diff_foreach()`.
Other than that, there are just minor errors.

Initial implementation of new diff patch API
Replacing the `git_iterator` object, this creates a simple API
for accessing the "patch" for any file pair in a diff list and
then gives indexed access to the hunks in the patch and the lines
in the hunk. This is the initial implementation of this revised
API - it is still broken, but at least builds cleanly.

Implement filters for status/diff blobs
This adds support to diff and status for running filters (a la crlf)
on blobs in the workdir before computing SHAs and before generating
text diffs. This ended up being a bit more code change than I had
thought since I had to reorganize some of the diff logic to minimize
peak memory use when filtering blobs in a diff.
This also adds a cap on the maximum size of data that will be loaded
to diff. I set it at 512Mb which should match core git. Right now
it is a #define in src/diff.h but it could be moved into the public
API if desired.

Diff iterators
This refactors the diff output code so that an iterator object
can be used to traverse and generate the diffs, instead of just
the `foreach()` style with callbacks. The code has been rearranged
so that the two styles can still share most functions.
This also replaces `GIT_REVWALKOVER` with `GIT_ITEROVER` and uses
that as a common error code for marking the end of iteration when
using a iterator style of object.

Make index add/append support core.filemode flag
This fixes git_index_add and git_index_append to behave more like
core git, preserving old filemode data in the index when adding
and/or appending with core.filemode = false.
This also has placeholder support for core.symlinks and
core.ignorecase, but those flags are not implemented (well,
symlinks has partial support for preserving mode information in
the same way that git does, but it isn't tested).

Minor fixes, cleanups, and clarifications
There are three actual changes in this commit:
1. When the trailing newline of a file is removed in a diff, the
change will now be reported with `GIT_DIFF_LINE_DEL_EOFNL` passed
to the callback. Previously, the `ADD_EOFNL` constant was given
which was just an error in my understanding of when the various
circumstances arose. `GIT_DIFF_LINE_ADD_EOFNL` is deprecated and
should never be generated. A new newline is simply an `ADD`.
2. Rewrote the `diff_delta__merge_like_cgit` function that contains
the core logic of the `git_diff_merge` implementation. The new
version doesn't actually have significantly different behavior,
but the logic should be much more obvious, I think.
3. Fixed a bug in `git_diff_merge` where it freed a string pool
while some of the string data was still in use. This led to
`git_diff_print_patch` accessing memory that had been freed.
The rest of this commit contains improved documentation in `diff.h`
to make the behavior and the equivalencies with core git clearer,
and a bunch of new tests to cover the various cases, oh and a minor
simplification of `examples/diff.c`.

Fix filemode comparison in diffs
File modes were both not being ignored properly on platforms
where they should be ignored, nor be diffed consistently on
platforms where they are supported.
This change adds a number of diff and status filemode change
tests. This also makes sure that filemode-only changes are
included in the diff output when they occur and that filemode
changes are ignored successfully when core.filemode is false.
There is no code that automatically toggles core.filemode
based on the capabilities of the current platform, so the user
still needs to be careful in their .git/config file.

Fix bugs for status with spaces and reloaded attrs
This fixes two bugs:
* Issue #728 where git_status_file was not working for files
that contain spaces. This was caused by reusing the "fnmatch"
parsing code from ignore and attribute files to interpret the
"pathspec" that constrained the files to apply the status to.
In that code, unescaped whitespace was considered terminal to
the pattern, so a file with internal whitespace was excluded
from the matched files. The fix was to add a mode to that code
that allows spaces and tabs inside patterns. This mode only
comes into play when parsing in-memory strings.
* The other issue was undetected, but it was in the recently
added code to reload gitattributes / gitignores when they were
changed on disk. That code was not clearing out the old values
from the cached file content before reparsing which meant that
newly added patterns would be read in, but deleted patterns
would not be removed. The fix was to clear the vector of
patterns in a cached file before reparsing the file.

Fix status for files under ignored dirs
There was a bug where tracked files inside directories that were
inside ignored directories where not being found by status. To
make that a little clearer, if you have a .gitignore with:
ignore/
And then have the following files:
ignore/dir/tracked <-- actually a tracked file
ignore/dir/untracked <-- should be ignored
Then we would show the tracked file as being removed (because
when we got the to contained item "dir/" inside the ignored
directory, we decided it was safe to skip -- bzzt, wrong!).
This update is much more careful about checking that we are
not skipping over any prefix of a tracked item, regardless of
whether it is ignored or not.
As documented in diff.c, this commit does create behavior that
still differs from core git with regards to the handling of
untracked files contained inside ignored directories. With
libgit2, those files will just not show up in status or diff.
With core git, those files don't show up in status or diff
either *unless* they are explicitly ignored by a .gitignore
pattern in which case they show up as ignored files.
Needless to say, this is a local behavior difference only, so
it should not be important and (to me) the libgit2 behavior
seems more consistent.
