Russell Belfer 74ded024 2013-06-17T17:03:34 Add "as_path" parameters to blob and buffer diffs This adds parameters to the four functions that allow for blob-to- blob and blob-to-buffer differencing (either via callbacks or by making a git_diff_patch object). These parameters let you say that filename we should pretend the blob has while doing the diff. If you pass NULL, there should be no change from the existing behavior, which is to skip using attributes for file type checks and just look at content. With the parameters, you can plug into the new diff driver functionality and get binary or non-binary behavior, plus function context regular expressions, etc. This commit also fixes things so that the git_diff_delta that is generated by these functions will actually be populated with the data that we know about the blobs (or buffers) so you can use it appropriately. It also fixes a bug in generating patches from the git_diff_patch objects created via these functions. Lastly, there is one other behavior change that may matter. If there is no difference between the two blobs, these functions no longer generate any diff callbacks / patches unless you have passed in GIT_DIFF_INCLUDE_UNMODIFIED. This is pretty natural, but could potentially change the behavior of existing usage.
Russell Belfer a1683f28 2013-06-14T16:18:04 More tests and bug fixes for status with rename This changes the behavior of the status RENAMED flags so that they will be combined with the MODIFIED flags if appropriate. If a file is modified in the index and also renamed, then the status code will have both the GIT_STATUS_INDEX_MODIFIED and INDEX_RENAMED bits set. If it is renamed but the OID has not changed, then just the GIT_STATUS_INDEX_RENAMED bit will be set. Similarly, the flags GIT_STATUS_WT_MODIFIED and GIT_STATUS_WT_RENAMED can both be set independently of one another. This fixes a serious bug where the check for unmodified files that was done at data load time could end up erasing the RENAMED state of a file that was renamed with no changes. Lastly, this contains a bunch of new tests for status with renames, including tests where the only rename changes are case changes. The expected results of these tests have to vary by whether the platform uses a case sensitive filesystem or not, so the expected data covers those platform differences separately.
Russell Belfer eefef642 2013-06-13T16:09:53 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).
Russell Belfer 6ea999bb 2013-06-13T15:52:12 Make index_insert keep existing case In a case insensitive index, if you attempt to add a file from disk with a different case pattern, the old case pattern in the index should be preserved. This fixes that (and a couple of minor warnings).
Russell Belfer 351888cf 2013-06-13T15:37:06 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.
Russell Belfer a3e8dbb4 2013-06-13T15:32:09 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).
Russell Belfer 3a68d7f0 2013-06-13T15:30:26 Fix broken status EXCLUDE_SUBMODULES logic The exclude submodules flag was not doing the right thing, in that a file with no diff between the head and the index and just a delete in the workdir could be excluded if submodules were excluded.

Vicent Martí 93da7af7 2013-06-12T14:52:47 Merge pull request #1642 from arrbee/diff-function-context Diff code reorg plus function context in diff headers
Russell Belfer 360f42f4 2013-06-12T14:18:09 Fix diff header naming issues This makes the git_diff_patch definition private to diff_patch.c and fixes a number of other header file naming inconsistencies to use `git_` prefixes on functions and structures that are shared between files.
Russell Belfer ef3374a8 2013-06-12T13:46:44 Improvements to git_array This changes the size data to uint32_t, fixes the array growth logic to use a simple 1.5x multiplier, and uses a generic inline function for growing the array to make the git_array_alloc API feel more natural (i.e. it returns a pointer to the new item).

Russell Belfer f9c824c5 2013-06-12T11:55:27 Add patch from blobs API This adds two new public APIs: git_diff_patch_from_blobs and git_diff_patch_from_blob_and_buffer, plus it refactors the code for git_diff_blobs and git_diff_blob_to_buffer so that they code is almost entirely shared between these APIs, and adds tests for the new APIs.
Russell Belfer 54faddd2 2013-06-12T11:54:11 Fix some diff driver memory leaks
Russell Belfer 42e6cf78 2013-06-11T17:45:14 Add diff drivers tests (and fix bugs) This adds real tests for user-configured diff drivers and in the process found a bunch of bugs.
Russell Belfer 5dc98298 2013-06-11T11:22:22 Implement regex pattern diff driver This implements the loading of regular expression pattern lists for diff drivers that search for function context in that way. This also changes the way that diff drivers update options and interface with xdiff APIs to make them a little more flexible.
Carlos Martín Nieto 24ec6999 2013-06-11T10:48:00 signature: extend trimming to more whitespace There are all sorts of misconfiguration in the wild. We already rely on the signature constructor to trim SP. Extend the logic to use `isspace` to decide whether a character should be trimmed.

Edward Thomson 690bf41c 2013-06-10T15:16:44 keep source similarity in rename detection
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 3e9e6cda 2013-06-07T09:54:33 Add safe memset and use it This adds a `git__memset` routine that will not be optimized away and updates the places where I memset() right before a free() call to use it.
Russell Belfer f7e56150 2013-06-05T15:41:42 Make mkdir early exit cases clearer There are two places where git_futils_mkdir should exit early or at least do less. The first is when using GIT_MKDIR_SKIP_LAST and having that flag leave no directory left to create; it was being handled previously, but the behavior was subtle. Now I put in a clear explicit check that exits early in that case. The second is when there is no directory to create, but there is a valid path that should be verified. I shifted the logic a bit so we'll be better about not entering the loop than that happens.
Russell Belfer 7000f3fa 2013-06-04T10:32:59 Move some diff helpers into separate file
Russell Belfer aad6967b 2013-05-29T21:52:21 Basic function context header This implements a basic callback to extract function context for a diff. It always uses the same search heuristic right now with no regular expressions or language-specific variants. Those will come next, I think.
Russell Belfer 999d4405 2013-06-05T12:02:28 Simplify git_futils_mkdir This routine was (is) pretty complicated, but given the recent changes, it seemed like it could be simplified a bit.
Vicent Marti 2e1fa15f 2013-06-05T19:00:16 I'm a dick
Russell Belfer b832ecf7 2013-06-05T09:46:51 Ensure git_futils_mkdir won't mkdir root This makes sure that git_futils_mkdir always skips over the root directory at a minimum, even on platforms where the root is not simply '/'. Also, this removes the GIT_WIN32 ifdef in favor of making EACCES as a potentially recoverable error on all platforms.
Vicent Martí e236b37f 2013-06-05T09:16:19 Merge pull request #1633 from jamill/directory_create_fix Allow creation of directories under the volume root in Win32
Jameson Miller daf98cb2 2013-06-04T14:49:39 Allow creation of directories under the volume root in Win32 We ran into an issue where cloning a repository to a folder directly underneath the root of a volume (e.g. 'd:\libgit2') would fail with an access denied error. This was traced down to a call to make a directory that is the root (e.g. 'd:') could return an error indicated access denied instead of an error indicating the path already exists. This change now handles the access denied error on Win32 and checks for the existence of the folder.
Vicent Martí 947fad4f 2013-06-03T09:28:58 Merge pull request #1624 from libgit2/vmg/full-ref-iterator Breaking RefDB changes
Scott J. Goldman dc33b3d7 2013-06-02T02:13:45 Don't bail on parsing commits with an invalid timezone git doesn't do that, and it's not something that's usually actionable to fix. if you have a git repository with one bad timezone in the history, it's too late to change it most likely.
Russell Belfer 03a89070 2013-05-31T21:49:40 Make git_index_read_tree preserve stat cache Instead of just blowing away the stat cache data when loading a new tree into the index, this checks if each loaded item has a corresponding existing item with the same OID and if so, copies the stat data from the old item to the new one so it will not be blown away.
Russell Belfer 1a42dd17 2013-05-31T14:13:11 Mutex init can fail It is obviously quite a serious problem if this happens, but mutex initialization can fail and we should detect it. It's a bit like a memory allocation failure, in that you're probably pretty screwed if this occurs, but at least we'll catch it.
Russell Belfer f658dc43 2013-05-31T14:09:58 Zero memory for major objects before freeing By zeroing out the memory when we free larger objects (i.e. those that serve as collections of other data, such as repos, odb, refdb), I'm hoping that it will be easier for libgit2 bindings to find errors in their object management code.
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.

yorah d17db2fd 2013-05-30T11:30:34 thread: fix segfault on Windows 64 bits `lpExitCode` is a pointer to a long. A long is 32 bits wide on Windows. It means that on Windows 64bits, `GetExitCodeThread()` doesn't set/clear the high-order bytes of the 64 bits memory space pointed at by `value_ptr`.

Edward Thomson c37fb41a 2013-05-25T12:35:55 qsort_r appeared in glibc 2.8
Russell Belfer 7a5ee3dc 2013-05-24T11:09:04 Add ~ expansion to global attributes and excludes This adds ~/ prefix expansion for the value of core.attributesfile and core.excludesfile, plus it fixes the fact that the attributes cache was holding on to the string data from the config for a long time (instead of making its own strdup) which could have caused a problem if the config was refreshed. Adds a test for the new expansion capability.
Russell Belfer d20b0449 2013-05-24T10:37:40 Clarify GIT_DIFF_INCLUDE_UNTRACKED_CONTENT option This improves the docs for GIT_DIFF_INCLUDE_UNTRACKED_CONTENT as well as the other flags related to UNTRACKED items in diff, plus it makes that flag now automatically turn on GIT_DIFF_INCLUDE_UNTRACKED which seems like a reasonable dwim type of change.
Russell Belfer 16adc9fa 2013-05-24T10:35:58 Typedef git_config_level_t and use it everywhere The GIT_CONFIG_LEVEL constants actually work well as an enum because they are mutually exclusive, so this adds a typedef to the enum and uses that everywhere that one of these constants are expected, instead of the old code that typically used an unsigned int.
Russell Belfer 2e62e7c2 2013-05-24T10:33:41 Docs for git_libgit2_opts and cache disable tweak This adds docs for the cache control options to git_libgit2_opts and also tweaks the cache code so that if the cache is disabled, then the next time we attempt to insert something into the cache in question, we will actually clear any old cached objects.
Russell Belfer 43efc449 2013-05-16T11:03:55 Ensure reuc vector is always valid In theory, if there was a problem reading the REUC data, the read_reuc() routine could have left uninitialized and invalid data in the git_index vector. This moves the line that inserts a new entry into the vector down to the bottom of the routine so we know all the content is already valid. Also, per @linquize, this uses calloc to ensure no uninitialized data.

Russell Belfer 49f70f2c 2013-05-23T15:48:06 Fill out diff rename test coverage This extends the rename tests to make sure that every rename scenario in the inner loop of git_diff_find_similar is actually exercised. Also, fixes an incorrect assert that was in one of the clauses that was not previously being exercised.

Russell Belfer f38cea97 2013-05-23T15:21:43 Move core.abbrev lookup out of diff print loop This moves the GIT_CVAR_ABBREV lookup out of the loop. Also, this fixes git_diff_print_raw to actually use that constant instead of hardcoding 7 characters.
Russell Belfer 67db583d 2013-05-23T15:06:07 More diff rename tests; better split swap handling This adds a couple more tests of different rename scenarios. Also, this fixes a problem with the case where you have two "split" deltas and the left half of one matches the right half of the other. That case was already being handled, but in the wrong order in a way that could result in bad output. Also, if the swap also happened to put the other two halves into the correct place (i.e. two files exchanged places with each other), then the second delta was left with the SPLIT flag set when it really should be cleared.
Russell Belfer c68b09dc 2013-05-23T11:52:34 Fix dereference of freed delta I was accidentally using a value that I had just freed. This moves the clearing of the delta internal flags into a better place.
Ben Straub 9c941ccf 2013-05-23T08:52:24 Merge pull request #1599 from nulltoken/topic/windows_resources Update windows resources to match the dll name
Russell Belfer a21cbb12 2013-05-22T10:37:12 Significant rename detection rewrite This flips rename detection around so instead of creating a forward mapping from deltas to possible rename targets, instead it creates a reverse mapping, looking at possible targets and trying to find a source that they could have been renamed or copied from. This is important because each output can only have a single source, but a given source could map to multiple outputs (in the form of COPIED records). Additionally, this makes a couple of tweaks to the public rename detection APIs, mostly renaming a couple of options that control the behavior to make more sense and to be more like core Git. I walked through the tests looking at the exact results and updated the expectations based on what I saw. The new code is different from the old because it cannot give some nonsense results (like A was renamed to both B and C) which were part of the outputs previously.
Axel Wagner 52f537e9 2013-05-22T02:04:12 Bugfix: Return NULL in push_leaf, when trie is full os->full was set 1, but the overflowed idx_leaf was still used to index into os->nodes a little later. Returning NULL fixes that.

Russell Belfer 4742148d 2013-05-20T13:41:39 Add more diff rename detection tests This adds a bunch more rename detection tests including checks vs the working directory, the new exact match options, some more whitespace variants, etc. This also adds a git_futils_writebuffer helper function and uses it in checkout. This is mainly added because I wanted an easy way to write out a git_buf to disk inside my test code.
Russell Belfer 9be5be47 2013-05-20T13:37:21 More git_diff_find_similar improvements - Add new GIT_DIFF_FIND_EXACT_MATCH_ONLY flag to do similarity matching without using the similarity metric (i.e. only compare the SHA). - Clean up the similarity measurement code to more rigorously distinguish between files that are not similar and files that are not comparable (previously, a 0 could either mean that the files could not be compared or that they were totally different) - When splitting a MODIFIED file into a DELETE/ADD pair, actually make a DELETED/UNTRACKED pair if the right side of the diff is from the working directory. This prevents an odd mix of ADDED and UNTRACKED files on workdir diffs.
Eitan Adler 038c1654 2013-05-19T01:41:00 Initialize loose_deleted before it is used for a check later on.
Russell Belfer d958e37a 2013-05-17T17:21:45 Fix issues with git_diff_find_similar There are a number of bugs in the rename code that only were obvious when I started testing it against large old repos with more complex patterns. (The code to do that testing is not ready to merge with libgit2, but I do plan to add more thorough tests.) This contains a significant number of changes and also tweaks the public API slightly to make emulating core git easier. Most notably, this separates the GIT_DIFF_FIND_AND_BREAK_REWRITES flag into FIND_REWRITES (which adds a self-similarity score to every modified file) and BREAK_REWRITES (which splits the modified deltas into add/remove pairs in the diff list). When you do a raw output of core git, rewrites show up as M090 or such, not at A and D output, so I wanted to be able to emulate that. Publicly, this also changes the flags to be uint16_t since we don't need values out of that range. Internally, this contains significant changes from a number of small bug fixes (like using the wrong side of the diff to decide if the object could be found in the ODB vs the workdir) to larger issues about which files can and should be compared and how the various edge cases of similarity scores should be treated. Honestly, I don't think this is the last update that will have to be made to this code, but I think this moves us closer to correct behavior and I tried to document the code so it would be easier to follow..
Russell Belfer 0293450e 2013-05-17T16:57:49 Fix delta compare to use correct pathname The delta cmp function needs to choose the correct path for ordering when a delta is ADDED, RENAMED, or COPIED.
Russell Belfer aadfa85b 2013-05-17T16:41:15 Add git_diff_print_raw printing helper Makes it easier to emulate the --raw option
