Russell Belfer 40ed4990 2014-02-11T14:45:37 Add diff threading tests and attr file cache locks This adds a basic test of doing simultaneous diffs on multiple threads and adds basic locking for the attr file cache because that was the immediate problem that arose from these tests.
Russell Belfer 082e82db 2014-01-27T11:45:06 Update Javascript userdiff driver and tests Writing a sample Javascript driver pointed out some extra whitespace handling that needed to be done in the diff driver. This adds some tests with some sample javascript code that I pulled off of GitHub just to see what would happen. Also, to clean up the userdiff test data, I did a "git gc" and packed up the test objects.
Russell Belfer c7c260a5 2014-01-23T16:12:39 Got some permission to use userdiff patterns I contacted a number of Git authors and lined up their permission to relicense their work for use in libgit2 and copied over their code for diff driver xfuncname patterns. At this point, the code I've copied is taken verbatim from core Git although Thomas Rast warned me that the C++ patterns, at least, really need an update. I've left off patterns where I don't feel like I have permission at this point until I hear from more authors.

Russell Belfer 2c65602e 2014-01-21T10:39:27 Import git drivers and test HTML driver Reorganize the builtin driver table slightly so that core Git builtin definitions can be imported verbatim. Then take a few of the core Git drivers and pull them in. This also creates a test of diffs with the builtin HTML driver which led to some small error handling fixes in the driver selection logic.
Russell Belfer a5a38643 2014-01-20T14:53:59 Initial take on builtin drivers with multiline This extends the diff driver parser to support multiline driver definitions along with ! prefixing for negated matches. This brings the driver function pattern parsing in line with core Git. This also adds an internal table of driver definitions and a fallback code path that will look in that table for diff drivers that are set with attributes without having a definition in the config file. Right now, I just populated the table with a kind of simple HTML definition that is similar to the core Git def.
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.

Russell Belfer a5f9b5f8 2013-07-05T16:59:38 Diff hunk context off by one on long lines The diff hunk context string that is returned to xdiff need not be NUL terminated because the xdiff code just copies the number of bytes that you report directly into the output. There was an off by one in the diff driver code when the header context was longer than the output buffer size, the output buffer length included the NUL byte which was copied into the hunk header. Fixes #1710
Russell Belfer 37f66e82 2013-06-12T15:21:21 Fix Windows warnings This fixes problems with missing function prototypes and 64-bit data issues on Windows.
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 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.
Russell Belfer 3eadfecd 2013-06-10T15:24:20 start implementing diff driver registry
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.
