Carlos Martín Nieto 11e2665e 2014-06-02T18:53:32 Formatting fixes for the docs These are some issues I found while playing around with the new parser for docurium.
Alan Rogers 61bef72d 2014-05-20T23:57:40 Start adding GIT_DELTA_UNREADABLE and GIT_STATUS_WT_UNREADABLE.
Russell Belfer 702efc89 2014-04-30T10:57:42 Make init_options fns use unsigned ints and macro Use an unsigned int for the version and add a helper macro so the code is simplified (and so the error message is a common string).
Russell Belfer 9c8ed499 2014-04-29T15:05:58 Remove trace / add git_diff_perfdata struct + api
Russell Belfer 7a2e56a3 2014-04-29T14:30:15 Get rid of redundant git_diff_options_init fn Since git_diff_init_options was introduced, remove this old fn.
Russell Belfer 94fb4aad 2014-04-28T14:48:41 Add diff option to update index stat cache When diff is scanning the working directory, if it finds a file where it is not sure if the index entry matches the working dir, it will recalculate the OID (which is pretty expensive). This adds a new flag to diff so that if the OID calculation finds that the file actually has not changed (i.e. just the modified time was altered or such), then it will refresh the stat cache in the index so that future calls to diff will not have to check the oid again.
Vicent Marti 212b6205 2014-04-23T09:27:15 Merge pull request #2291 from ethomson/patch_binary patch: emit deflated binary patches (optionally)
Edward Thomson e349ed50 2014-04-22T14:58:33 patch: emit binary patches (optionally)
Russell Belfer 8d09efa2 2014-04-22T12:33:27 Use git_diff_get_stats in example/diff + refactor This takes the `--stat` and related example options in the example diff.c program and converts them to use the `git_diff_get_stats` API which nicely formats stats for you. I went to add bar-graph scaling to the stats formatter and noticed that the `git_diff_stats` structure was holding on to all of the `git_patch` objects. Unfortunately, each of these objects keeps the full text of the diff in memory, so this is very expensive. I ended up modifying `git_diff_stats` to keep just the data that it needs to keep and allowed it to release the patches. Then, I added width scaling to the output on top of that. In making the diff example program match 'git diff' output, I ended up removing an newline from the sumamry output which I then had to compensate for in the email formatting to match the expectations. Lastly, I went through and refactored the tests to use a couple of helper functions and reduce the overall amount of code there.
Russell Belfer 12e422a0 2014-04-21T16:08:05 Some doc and examples/diff.c changes I was playing with "git diff-index" and wanted to be able to emulate that behavior a little more closely with the diff example. Also, I wanted to play with running `git_diff_tree_to_workdir` directly even though core Git doesn't exactly have the equivalent, so I added a command line option for that and tweaked some other things in the example code. This changes a minor output thing in that the "raw" print helper function will no longer add ellipses (...) if the OID is not actually abbreviated.
Jacques Germishuys d8cc1fb6 2014-04-11T19:15:15 Introduce git_diff_format_email and git_diff_commit_as_email
Jacques Germishuys 360314c9 2014-04-11T19:03:29 Introduce git_diff_get_stats, git_diff_stats_files_changed, git_diff_stats_insertions, git_diff_stats_deletions and git_diff_stats_to_buf
Matthew Bowen b9f81997 2014-03-05T21:49:23 Added function-based initializers for every options struct. The basic structure of each function is courtesy of arrbee.
Russell Belfer 6789b7a7 2014-02-27T14:13:22 Add buffer to buffer diff and patch APIs This adds `git_diff_buffers` and `git_patch_from_buffers`. This also includes a bunch of internal refactoring to increase the shared code between these functions and the blob-to-blob and blob-to-buffer APIs, as well as some higher level assert helpers in the tests to also remove redundancy.
Carlos Martín Nieto 86bfc3e1 2014-01-24T20:30:10 diff: change id abbrev option's name to id_abbrev Same as the other commits in the series, we use 'id' when talking about thing rather than the datatype.
Carlos Martín Nieto 9950bb4e 2014-01-24T20:23:17 diff: rename the file's 'oid' to 'id' In the same vein as the previous commits in this series.
Russell Belfer 373cf6a9 2013-12-09T10:17:47 Update docs for new callback return value behavior
Russell Belfer 9f77b3f6 2013-11-25T14:21:34 Add config read fns with controlled error behavior This adds `git_config__lookup_entry` which will look up a key in a config and return either the entry or NULL if the key was not present. Optionally, it can either suppress all errors or can return them (although not finding the key is not an error for this function). Unlike other accessors, this does not normalize the config key string, so it must only be used when the key is known to be in normalized form (i.e. all lower-case before the first dot and after the last dot, with no invalid characters). This also adds three high-level helper functions to look up config values with no errors and a fallback value. The three functions are for string, bool, and int values, and will resort to the fallback value for any error that arises. They are: * `git_config__get_string_force` * `git_config__get_bool_force` * `git_config__get_int_force` None of them normalize the config `key` either, so they can only be used for internal cases where the key is known to be in normal format.

Ben Straub a6ebc2bd 2013-12-04T15:17:39 Introduce GIT_DIFF_FIND_BY_CONFIG
Russell Belfer f62c174d 2013-12-02T13:49:58 GIT_DIFF_FIND_REMOVE_UNMODIFIED sounds better
Russell Belfer 97ad85b8 2013-12-02T13:30:05 Add GIT_DIFF_FIND_DELETE_UNMODIFIED flag When doing copy detection, it is often necessary to include UNMODIFIED records in the git_diff so they are available as source records for GIT_DIFF_FIND_COPIES_FROM_UNMODIFIED. Yet in the final diff, often you will not want to have these UNMODIFIED records. This adds a flag which marks these UNMODIFIED records for deletion from the diff list so they will be removed after the rename detect phase is over.
Nick Hengeveld d8e7ffc2 2013-11-18T14:03:25 Add content offset to git_diff_line For additions and deletions, external consumers like subversion can make use of the content offset to generate diffs in their proprietary formats.
Russell Belfer a5c16f3c 2013-11-01T10:18:03 Add git_diff_options_init helper Sometimes the static initializer for git_diff_options cannot be used and since setting them to all zeroes doesn't actually work quite right, this adds a new helper for that situation. This also adds an explicit new value to the submodule settings options to be used when those enums need static initialization.
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 7ce60099 2013-10-22T11:12:44 Fix typo
Russell Belfer 5de4ec81 2013-10-21T15:36:38 Implement patience and minimal diff flags It seems that to implement these options, we just have to pass the appropriate flags through to the libxdiff code taken from core git. So let's do it (and add a test).
Russell Belfer 3b5f7954 2013-10-21T13:42:42 Create git_diff_line and extend git_diff_hunk Instead of having functions with so very many parameters to pass hunk and line data, this takes the existing git_diff_hunk struct and extends it with more hunk data, plus adds a git_diff_line. Those structs are used to pass back hunk and line data instead of the old APIs that took tons of parameters. Some work that was previously only being done for git_diff_patch creation (scanning the diff content for exact line counts) is now done for all callbacks, but the performance difference should not be noticable.
Russell Belfer 74a627f0 2013-10-21T09:07:19 Tweak to git_diff_delta structure for nfiles While the base git_diff_delta structure always contains two files, when we introduce conflict data, it will be helpful to have an indicator when an additional file is involved.
Russell Belfer 10672e3e 2013-10-15T15:10:07 Diff API cleanup This lays groundwork for separating formatting options from diff creation options. This groups the formatting flags separately from the diff list creation flags and reorders the options. This also tweaks some APIs to further separate code that uses patches from code that just looks at git_diffs.
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.
Edward Thomson 17c7fbf6 2013-08-21T14:07:53 Split rewrites, status doesn't return rewrites Ensure that we apply splits to rewrites, even if we're not interested in examining it closely for rename/copy detection. In keeping with core git, status should not display rewrites, it should simply show files as "modified".
Russell Belfer eb1c1707 2013-07-23T15:45:58 Restore GIT_DIFF_LINE_BINARY usage This restores the usage of GIT_DIFF_LINE_BINARY for the diff output line that reads "Binary files x and y differ" so that it can be optionally colorized independently of the file header.
Russell Belfer 197b8966 2013-07-23T14:34:31 Add hunk/file headers to git_diff_patch_size This allows git_diff_patch_size to account for hunk headers and file headers in the returned size. This required some refactoring of the code that is used to print file headers so that it could be invoked by the git_diff_patch_size API. Also this increases the test coverage and fixes an off-by-one bug in the size calculation when newline changes happen at the end of the file.
Russell Belfer b4a4cf24 2013-07-22T16:07:56 Add git_diff_patch_size() API This adds a new API to get the size in bytes of the diffs in a git_diff_patch object.
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 2b672d5b 2013-07-08T22:46:36 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.
Andreas Linde e1967164 2013-06-24T15:33:41 Fixed most documentation header bugs Fixed a few header @param and @return typos with the help of -Wdocumentation in Xcode. The following warnings have not been fixed: common.h:213 - Not sure how the documentation format is for '...' notes.h:102 - Correct @param name but empty text notes.h:111 - Correct @param name but empty text pack.h:140 - @return missing text pack.h:148 - @return missing text
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 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 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.
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 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 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.
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.
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 aadfa85b 2013-05-17T16:41:15 Add git_diff_print_raw printing helper Makes it easier to emulate the --raw option
Russell Belfer d63eec69 2013-05-07T04:44:08 Improve diff function docs
Russell Belfer e35e2684 2013-05-07T04:32:17 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.
Russell Belfer 61c00541 2013-04-29T06:21:56 Update comment for clarity
Russell Belfer e26b14c0 2013-04-26T15:35:47 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.
Russell Belfer 0c289dd7 2013-03-25T16:40:16 Recursing into ignored dirs for diff and status This implements working versions of GIT_DIFF_RECURSE_IGNORED_DIRS and GIT_STATUS_OPT_RECURSE_IGNORED_DIRS along with some tests for the newly available behaviors. This is not turned on by default for status, but can be accessed via the options to the extended version of the command.
Carlos Martín Nieto 1aa5318a 2013-03-09T16:04:34 diff: allow asking for diffs with no context Previously, 0 meant default. This is problematic, as asking for 0 context lines is a valid thing to do. Change GIT_DIFF_OPTIONS_INIT to default to three and stop treating 0 as a magic value. In case no options are provided, make sure the options in the diff object default to 3.
Russell Belfer d4b747c1 2013-02-21T16:44:44 Add diff rename tests with partial similarity This adds some new tests that actually exercise the similarity metric between files to detect renames, copies, and split modified files that are too heavily modified. There is still more testing to do - these tests are just partially covering the cases. There is also one bug fix in this where a change set with only MODIFY being broken into ADD/DELETE (due to low self-similarity) without any additional RENAMED entries would end up not processing the split requests (because the num_rewrites counter got reset).
Russell Belfer 960a04dd 2013-02-21T12:40:33 Initial integration of similarity metric to diff This is the initial integration of the similarity metric into the `git_diff_find_similar()` code path. The existing tests all pass, but the new functionality isn't currently well tested. The integration does go through the pluggable metric interface, so it should be possible to drop in an alternative to the internal metric that libgit2 implements. This comes along with a behavior change for an existing interface; namely, passing two NULLs to git_diff_blobs (or passing NULLs to git_diff_blob_to_buffer) will now call the file_cb parameter zero times instead of one time. I know it's strange that that change is paired with this other change, but it emerged from some initialization changes that I ended up making.
Russell Belfer 71a3d27e 2013-02-08T10:06:47 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.
Russell Belfer 9bc8be3d 2013-02-19T10:25:41 Refine pluggable similarity API This plugs in the three basic similarity strategies for handling whitespace via internal use of the pluggable API. In so doing, I realized that the use of git_buf in the hashsig API was not needed and actually just made it harder to use, so I tweaked that API as well. Note that the similarity metric is still not hooked up in the find_similarity code - this is just setting out the function that will be used.
Russell Belfer a235e9d3 2013-02-15T14:12:43 Pluggable similarity metric API
yorah 0d64ba48 2013-01-25T17:35:46 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 diff process will be aborted - 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
Russell Belfer f1e2735c 2013-01-30T11:10:39 Add helper for diff line stats This adds a `git_diff_patch_line_stats()` API that gets the total number of adds, deletes, and context lines in a patch. This will make it a little easier to emulate `git diff --stat` and the like. Right now, this relies on generating the `git_diff_patch` object, which is a pretty heavyweight way to get stat information. At some future point, it would probably be nice to be able to get this information without allocating the entire `git_diff_patch`, but that's a much larger project.

Russell Belfer f2b7f7a6 2013-01-07T15:44:22 Share git_diff_blobs/git_diff_blob_to_buffer code This moves the implementation of these two APIs into common code that will be shared between the two. Also, this adds tests for the `git_diff_blob_to_buffer` API. Lastly, this adds some extra `const` to a few places that can use it.

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 793c4385 2012-11-20T16:36:06 Update diff callback param order This makes the diff functions that take callbacks both take the payload parameter after the callback function pointers and pass the payload as the last argument to the callback function instead of the first. This should make them consistent with other callbacks across the API.

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 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.
Vicent Martí 1362a983 2012-11-02T10:00:28 Merge pull request #1014 from arrbee/diff-rename-detection Initial implementation of diff rename detection
Russell Belfer db106d01 2012-10-30T09:40:50 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.
Russell Belfer cb7180a6 2012-10-25T11:48:39 Add git_diff_patch_print This adds a `git_diff_patch_print()` API which is more like the existing API to "print" a patch from an entire `git_diff_list` but operates on a single `git_diff_patch` object. Also, it rewrites the `git_diff_patch_to_str()` API to use that function (making it very small).
Russell Belfer 93cf7bb8 2012-10-24T20:56:32 Add git_diff_patch_to_str API This adds an API to generate a complete single-file patch text from a git_diff_patch object.
Russell Belfer b4f5bb07 2012-10-23T16:40:51 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.

Russell Belfer 0d64bef9 2012-10-05T15:56:57 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.
Russell Belfer 95f5f1e6 2012-10-02T13:57:15 Cleanup TYPECHANGE support This is just some cleanup code, rearranging some of the checkout code where TYPECHANGE support was added and adding some comments to the diff header regarding the constants.
Russell Belfer bc16fd3e 2012-09-28T13:40:02 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.
Russell Belfer dfbff793 2012-10-08T15:14:12 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.

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 bae957b9 2012-09-25T16:31:46 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!
Russell Belfer 64286308 2012-09-25T10:48:50 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.
Russell Belfer 9a12a625 2012-09-18T15:13:07 New take on iterating over diff content Allow diff deltas to be accessed by index and make patch generation explicit with hunk and line access by index as well.

Russell Belfer 1f35e89d 2012-09-11T12:03:33 Fix diff binary file detection In the process of adding tests for the max file size threshold (which treats files over a certain size as binary) there seem to be a number of problems in the new code with detecting binaries. This should fix those up, as well as add a test for the file size threshold stuff. Also, this un-deprecates `GIT_DIFF_LINE_ADD_EOFNL`, since I finally found a legitimate situation where it would be returned.
Russell Belfer e597b189 2012-09-10T11:49:12 Move diff max_size to public API This commit adds a max_size value in the public `git_diff_options` structure so that the user can automatically flag blobs over a certain size as binary regardless of other properties. Also, and perhaps more importantly, this moves binary detection to be as early as possible in the diff traversal inner loop and makes sure that we stop loading objects as soon as we decide that they are binary.
Russell Belfer b36effa2 2012-09-10T09:59:14 Replace git_diff_iterator_num_files with progress The `git_diff_iterator_num_files` API was problematic, since we don't actually know the exact number of files to be iterated over until we load those files into memory. This replaces it with a new `git_diff_iterator_progress` API that goes from 0 to 1, and moves and renamed the old API for the internal places that can tolerate a max value instead of an exact value.
