We cannot know from looking at .gitmodules whether a directory is a submodule or not. We need the index or tree we are comparing against to tell us. Otherwise we have to assume the entry in .gitmodules is stale or otherwise invalid. Thus we pass the index of the repository into the workdir iterator, even if we do not want to compare against it. This follows what git does, which even for `git diff <tree>`, it will consider staged submodules as such.

The diff code was using an "ignored_prefix" directory to track if a parent directory was ignored that contained untracked files alongside tracked files. Unfortunately, when negative ignore rules were used for directories inside ignored parents, the wrong rules were applied to untracked files inside the negatively ignored child directories. This commit moves the logic for ignore containment into the workdir iterator (which is a better place for it), so the ignored-ness of a directory is contained in the frame stack during traversal. This allows a child directory to override with a negative ignore and yet still restore the ignored state of the parent when we traverse out of the child. Along with this, there are some problems with "directory only" ignore rules on container directories. Given "a/*" and "!a/b/c/" (where the second rule is a directory rule but the first rule is just a generic prefix rule), then the directory only constraint was having "a/b/c/d/file" match the first rule and not the second. This was fixed by having ignore directory-only rules test a rule against the prefix of a file with LEADINGDIR enabled. Lastly, spot checks for ignores using `git_ignore_path_is_ignored` were tested from the top directory down to the bottom to deal with the containment problem, but this is wrong. We have to test bottom to top so that negative subdirectory rules will be checked before parent ignore rules. This does change the behavior of some existing tests, but it seems only to bring us more in line with core Git, so I think those changes are acceptable.

This adds an option to refresh the stat cache while generating status. It also rips out the GIT_PERF stuff I had an makes use of the trace API to keep statistics about what happens during diff.

In the iterator, distinguish between ignores and empty directories so that diff and status can ignore empty directories, but checkout and stash can treat them as untracked items.
Russell Belfer committed -
When diff finds an untracked directory, it emulates Git behavior by looking inside the directory to see if there are any untracked items inside it. If there are only ignored items inside the dir, then diff considers it ignored, even if there is no direct ignore rule for it. Checkout was not copying this behavior - when it found an untracked directory, it just treated it as untracked. Unfortunately, when combined with GIT_CHECKOUT_REMOVE_UNTRACKED, this made is seem that checkout (and stash, which uses checkout) was removing ignored items when you had only asked it to remove untracked ones. This commit moves the logic for advancing past an untracked dir while scanning for non-ignored items into an iterator helper fn, and uses that for both diff and checkout.

This doesn't actual do string precompose but it puts the hooks in place into the iterators and the git_path_dirload function so that the actual precompose work is ready to go.

This adds the ability for checkout to write to a target directory instead of having to use the working directory of the repository. This makes it easier to do exports of repository data and the like. This is similar to, but not quite the same as, the --prefix option to `git checkout-index` (this will always be treated as a directory name, not just as a simple text prefix). As part of this, the workdir iterator was extended to take the path to the working directory as a parameter and fallback on the git_repository_workdir result only if it's not specified. Fixes #1332

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.

This adds a new variant iterator that is a raw filesystem iterator for scanning directories from a root. There is still more work to do to blend this with the working directory iterator.

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.

Since the case sensitivity is moved into the respective iterators, this removes the spoolandsort iterator code.

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.

This makes tree iterators directly support case insensitivity by using a secondary index that can be sorted by icase. Also, this fixes the ambiguity check in the git_status_file API to also be case insensitive. Lastly, this adds new test cases for case insensitive range boundary checking for all types of iterators. With this change, it should be possible to deprecate the spool and sort iterator, but I haven't done that yet.
Russell Belfer committed -
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.

In preparation for further iterator changes, this cleans up a few small things in the iterator API: * removed the git_iterator_for_repo_index_range API * made git_iterator_free not be inlined * minor param name and test function name tweaks

The spoolandsort iterator changes got sort-of cherry picked out of this branch and so I dropped the commit when rebasing; however, there were a few small changes that got dropped as well (since the version merged upstream wasn't quite the same as what I dropped).

Make checkout update entries in the index for all files that are updated and/or removed, unless flag GIT_CHECKOUT_DONT_UPDATE_INDEX is given. To do this, iterators were extended to allow a little more introspection into the index being iterated over, etc.

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.

The `git_iterator_reset` command has not been working in all cases particularly when there is a start and end range. This fixes it and adds tests for it, and also extends it with the ability to update the start/end range strings when an iterator is reset.

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.

The index iterator could previously only be created from a repo object, but this allows creating an iterator from a `git_index` object instead (while keeping, though renaming, the old function).

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.

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.

The goal of this work is to rewrite git_status_file to use the same underlying code as git_status_foreach. This is done in 3 phases: 1. Extend iterators to allow ranged iteration with start and end prefixes for the range of file names to be covered. 2. Improve diff so that when there is a pathspec and there is a common non-wildcard prefix of the pathspec, it will use ranged iterators to minimize excess iteration. 3. Rewrite git_status_file to call git_status_foreach_ext with a pathspec that covers just the one file being checked. Since ranged iterators underlie the status & diff implementation, this is actually fairly efficient. The workdir iterator does end up loading the contents of all the directories down to the single file, which should ideally be avoided, but it is pretty good.

When a repo is first created, there is no HEAD yet and attempting to diff files in the index was showing nothing because a tree iterator could not be constructed. This adds an "empty" iterator and falls back on that when the head cannot be looked up.

This is a major reorganization of the diff code. This changes the diff functions to use the iterators for traversing the content. This allowed a lot of code to be simplified. Also, this moved the functions relating to outputting a diff into a new file (diff_output.c). This includes a number of other changes - adding utility functions, extending iterators, etc. plus more tests for the diff code. This also takes the example diff.c program much further in terms of emulating git-diff command line options.

This makes two changes to iterator behavior: first, advance can optionally do the work of returning the new current value. This is such a common pattern that it really cleans up usage. Second, for workdir iterators, this removes automatically iterating into directories. That seemed like a good idea, but when an entirely new directory hierarchy is introduced into the workdir, there is no reason to iterate into it if there are no corresponding entries in the tree/index that it is being compared to. This second change actually wasn't a lot of code because not descending into directories was already the behavior for ignored directories. This just extends that to all directories.

This create a new git_iterator type of object that provides a uniform interface for iterating over the index, an arbitrary tree, or the working directory of a repository. As part of this, git ignore support was extended to support push and pop of directory-based ignore files as the working directory is being traversed (so the array of ignores does not have to be recreated at each directory during traveral). There are a number of other small utility functions in buffer, path, vector, and fileops that are included in this patch that made the iterator implementation cleaner.
