Russell Belfer 4bf630b6 2013-10-31T14:36:52 Make diff and status perform soft index reload This changes `git_index_read` to have two modes - a hard index reload that always resets the index to match the on-disk data (which was the old behavior) and a soft index reload that uses the timestamp / file size information and only replaces the index data if the file on disk has been modified. This then updates the git_status code to do a soft reload unless the new GIT_STATUS_OPT_NO_REFRESH flag is passed in. This also changes the behavior of the git_diff functions that use the index so that when an index is not explicitly passed in (i.e. when the functions call git_repository_index for you), they will also do a soft reload for you. This intentionally breaks the file signature of git_index_read because there has been some confusion about the behavior previously and it seems like all existing uses of the API should probably be examined to select the desired behavior.
Russell Belfer 3ff1d123 2013-10-11T14:51:54 Rename diff objects and split patch.h This makes no functional change to diff but renames a couple of the objects and splits the new git_patch (formerly git_diff_patch) into a new header file.
Russell Belfer 14997dc5 2013-10-08T12:45:43 More filemode cleanups for FAT on MacOS This cleans up some additional issues. The main change is that on a filesystem that doesn't support mode bits, libgit2 will now create new blobs with GIT_FILEMODE_BLOB always instead of being at the mercy to the filesystem driver to report executable or not. This means that if "core.filemode" lies and claims that filemode is not supported, then we will ignore the executable bit from the filesystem. Previously we would have allowed it. This adds an option to the new git_repository_reset_filesystem to recurse through submodules if desired. There may be other types of APIs that would like a "recurse submodules" option, but this one is particularly useful. This also has a number of cleanups, etc., for related things including trying to give better error messages when problems come up from the filesystem. For example, the FAT filesystem driver on MacOS appears to return errno EINVAL if you attempt to write a filename with invalid UTF-8 in it. We try to capture that with a better error message now.
Carlos Martín Nieto 605da51a 2013-09-17T09:50:30 No such thing as an orphan branch Unfortunately git-core uses the term "unborn branch" and "orphan branch" interchangeably. However, "orphan" is only really there for the checkout command, which has the `--orphan` option so it doesn't actually create the branch. Branches never have parents, so the distinction of a branch with no parents is odd to begin with. Crucially, the error messages deal with unborn branches, so let's use that.
Nikolai Vladimirov f1af935b 2013-08-05T21:53:09 submodule: check alloc and name presense
nulltoken b3a559dd 2013-07-13T13:55:03 submodule: Fix memory leaks
Russell Belfer b8df28a5 2013-06-30T08:38:10 Clean up left over alloc change
Russell Belfer f9775a37 2013-06-29T23:22:31 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.
Russell Belfer 1aad6137 2013-06-29T13:16:33 Submodule status improvements This fixes the way that submodule status is checked to bypass just about all of the caching in the submodule object. Based on the ignore value, it will try to do the minimum work necessary to find the current status of the submodule - but it will actually go to disk to get all of the current values. This also removes the custom refcounting stuff in favor of the common git_refcount style. Right now, it is still for internal purposes only, but it should make it easier to add true submodule refcounting in the future with a public git_submodule_free call that will allow bindings not to worry about the submodule object getting freed from underneath them.
Russell Belfer e807860f 2013-06-27T16:52:38 Add timestamp check to submodule status This is probably not the final form of this change, but this is a preliminary version of checking a timestamp to see if the cached working directory HEAD OID matches the current. Right now, this uses the timestamp on the index and is, like most of our timestamp checking, subject to having only second accuracy.
Russell Belfer 1e9dd60f 2013-06-27T22:29:05 Test submodules with empty index or orphaned head In both of these cases, the submodule data should still be loaded just (obviously) without the data that comes from either the index or the HEAD. This fixes a bug in the orphaned head case.
Russell Belfer 22b6b82f 2013-06-20T12:16:06 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.
Russell Belfer 114f5a6c 2013-06-10T10:10:39 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.
Russell Belfer cee695ae 2013-05-31T12:18:43 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.
Russell Belfer 155ee751 2013-05-01T05:34:01 Add error messages for failed submodule lookup
Russell Belfer 83041c71 2013-04-19T11:52:04 Move git_config_backend to include/git2/sys Moving backend implementor objects into include/git2/sys so the APIs can be isolated from the ones that normal libgit2 users would be likely to use.
Carlos Martín Nieto a258d8e3 2013-03-30T03:39:19 branch: rename 'tracking' to 'upstream' The term 'tracking' is overloaded. Help distinguish what we mean by using 'upstream' for this part of the library.
Russell Belfer 37ee70fa 2013-03-25T22:19:39 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 GIT_DIFF_IGNORE_SUBMODULES so it be more diligent about avoiding 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).
Arkadiy Shapkin 10c06114 2013-03-17T04:46:46 Several warnings detected by static code analyzer fixed Implicit type conversion argument of function to size_t type Suspicious sequence of types castings: size_t -> int -> size_t Consider reviewing the expression of the 'A = B == C' kind. The expression is calculated as following: 'A = (B == C)' Unsigned type is never < 0
Russell Belfer 169dc616 2013-03-05T16:10:05 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.

Vicent Martí ddcb28a4 2013-01-17T16:56:57 Merge pull request #1239 from ethomson/index_remove add an index_remove_bypath that removes conflicts
Russell Belfer 4b181037 2013-01-08T13:39:15 Minor iterator API cleanups 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
Edward Thomson 25743bd7 2013-01-12T13:47:56 add an index_remove_bypath that removes conflicts, renamed add_from_workdir to match
Edward Thomson 359fc2d2 2013-01-08T17:07:25 update copyrights
Russell Belfer a9a73007 2012-12-20T16:16:22 Submodule caching fix and location API This adds a new API to the submodule interface that just returns where information about the submodule was found (e.g. config file only or in the HEAD, index, or working directory). Also, the old "refresh" call was potentially keeping some stale submodule data around, so this simplfies that code and literally discards the old cache, then reallocates.
Russell Belfer 56c72b75 2012-12-17T11:00:53 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
Russell Belfer 9950d27a 2012-12-06T13:26:58 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.

Russell Belfer 7bf87ab6 2012-11-28T09:58:48 Consolidate text buffer functions There are many scattered functions that look into the contents of buffers to do various text manipulations (such as escaping or unescaping data, calculating text stats, guessing if content is binary, etc). This groups all those functions together into a new file and converts the code to use that. This has two enhancements to existing functionality. The old text stats function is significantly rewritten and the BOM detection code was extended (although largely we can't deal with anything other than a UTF8 BOM).
Sascha Cunz 7cdad6c7 2012-11-28T12:43:12 Fix uninitialized variable clang-SVN HEAD kindly provided my the info, that sm_repo maybe uninitialized when we want to free it (If the expression in line 358 or 359/360 evaluate to true, we jump to "cleanup", where we'd use sm_repo uninitialized).

Ben Straub 2508cc66 2012-11-18T21:38:08 Rename ref and reflog apis for consistency
Russell Belfer bbe6dbec 2012-11-14T23:29:48 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.
Russell Belfer bad68c0a 2012-11-13T14:02:59 Add iterator for git_index object 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).
Russell Belfer 5735bf5e 2012-11-13T13:58:29 Fix diff API to better parameter order The diff API is not in the parameter order one would expect from other libgit2 APIs. This fixes that.
Russell Belfer 55cbd05b 2012-11-08T16:56:34 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.
Edward Thomson f45ec1a0 2012-10-29T20:04:21 index refactoring
yorah a1abe66a 2012-09-10T12:11:02 Add config level support in the config API Added `struct git_config_entry`: a git_config_entry contains the key, the value, and the config file level from which a config element was found. Added `git_config_open_level`: build a single-level focused config object from a multi-level one. We are now storing `git_config_entry`s in the khash of the config_file
nulltoken 74a24005 2012-09-21T10:28:20 refs: use constants for well-known names
Russell Belfer cc5bf359 2012-09-28T09:08:09 Clean up Win64 warnings
Russell Belfer 5f69a31f 2012-09-24T20:52:34 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.
Russell Belfer 17b06f4d 2012-09-07T15:49:08 Add missing accessor for fetchRecurseSubmodules When `git_submodule` became an opaque structure, I forgot to add accessor functions for the fetchRecurseSubmodules config setting. This fixes that.
Russell Belfer f335ecd6 2012-08-30T14:24:16 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.
Russell Belfer 97a17e4e 2012-08-24T12:19:22 Fix valgrind warnings and spurious error messages Just clean up valgrind warnings about uninitialized memory and also clear out errno in some cases where it results in a false error message being generated at a later point.
Russell Belfer 5f4a61ae 2012-08-09T19:43:25 Working implementation of git_submodule_status This is a big redesign of the git_submodule_status API and the implementation of the redesigned API. It also fixes a number of bugs that I found in other parts of the submodule API while writing the tests for the status part. This also fixes a couple of bugs in the iterators that had not been noticed before - one with iterating when there is a gitlink (i.e. separate-work-dir) and one where I was treating anything even vaguely submodule-like as a submodule, more aggressively than core git does.
Russell Belfer 0c8858de 2012-08-03T14:28:07 Fix valgrind issues and leaks This fixes up a number of problems flagged by valgrind and also cleans up the internal `git_submodule` allocation handling overall with a simpler model.
Russell Belfer aa13bf05 2012-08-02T13:00:58 Major submodule rewrite This replaces the old submodule API with a new extended API that supports most of the things that can be done with `git submodule`.
Russell Belfer 72ee0787 2012-07-12T11:48:12 Isolate khash inlines from global namespace khash.h was globally #define'ing "inline" which messes with other files. Let's keep it as "kh_inline".

Vicent Martí 29e948de 2012-05-10T10:38:10 global: Change parameter ordering in API Consistency is good.
Russell Belfer c2b67043 2012-04-25T15:20:28 Rename git_khash_str to git_strmap, etc. This renamed `git_khash_str` to `git_strmap`, `git_hash_oid` to `git_oidmap`, and deletes `git_hashtable` from the tree, plus adds unit tests for `git_strmap`.
Russell Belfer 01fed0a8 2012-04-25T10:36:01 Convert hashtable usage over to khash This updates khash.h with some extra features (like error checking on allocations, ability to use wrapped malloc, foreach calls, etc), creates two high-level wrappers around khash: `git_khash_str` and `git_khash_oid` for string-to-void-ptr and oid-to-void-ptr tables, then converts all of the old usage of `git_hashtable` over to use these new hashtables. For `git_khash_str`, I've tried to create a set of macros that yield an API not too unlike the old `git_hashtable` API. Since the oid hashtable is only used in one file, I haven't bother to set up all those macros and just use the khash APIs directly for now.
Carlos Martín Nieto 8e8b6b01 2012-04-04T13:13:43 Clean up valgrind warnings
Russell Belfer 95dfb031 2012-03-30T14:40:50 Improve config handling for diff,submodules,attrs This adds support for a bunch of core.* settings that affect diff and status, plus fixes up some incorrect implementations of those settings from before. Also, this cleans up the handling of config settings in the new submodules code and in the old attrs/ignore code.
Russell Belfer bfc9ca59 2012-03-28T16:45:36 Added submodule API and use in status When processing status for a newly checked out repo, it is possible that there will be submodules that have not yet been initialized. The only way to distinguish these from untracked directories is to have some knowledge of submodules. This commit adds a new submodule API which, given a name or path, can determine if it appears to be a submodule and can give information about the submodule.
