Edward Thomson 0972c592 2014-01-29T13:14:00 Two-phase index merging When three-way merging indexes, we previously changed each path as we read them, which would lead to us adding an index entry for 'foo', then removing an index entry for 'foo/file'. With the new index requirements, this is not allowed. Removing entries in the merged index, then adding them, resolves this. In the previous example, we now remove 'foo/file' before adding 'foo'.
Carlos Martín Nieto a1bbc0ce 2014-01-25T04:14:37 merge: rename _oid() -> id() Following the rest of the series, use 'id' when refering to the value.
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.
Carlos Martín Nieto d541170c 2014-01-24T11:36:41 index: rename an entry's id to 'id' This was not converted when we converted the rest, so do it now.

Edward Thomson 0e1ba46c 2014-01-19T20:03:13 Remove the "merge none" flag The "merge none" (don't automerge) flag was only to aide in merge trivial tests. We can easily determine whether merge trivial resulted in a trivial merge or an automerge by examining the REUC after automerge has completed.
Edward Thomson e651e8e2 2014-01-19T15:05:08 Introduce diff3 mode for checking out conflicts
Edward Thomson 6b92c99b 2014-01-19T01:20:25 Don't try to merge binary files
Edward Thomson c1d648c5 2014-01-08T18:29:42 merge_file should use more aggressive levels The default merge_file level was XDL_MERGE_MINIMAL, which will produce conflicts where there should not be in the case where both sides were changed identically. Change the defaults to be more aggressive (XDL_MERGE_ZEALOUS) which will more aggressively compress non-conflicts. This matches git.git's defaults. Increase testing around reverting a previously reverted commit to illustrate this problem.
Vicent Marti 79194bcd 2013-12-13T06:20:19 Merge pull request #1986 from libgit2/rb/error-handling-cleanups Clean up some error handling and change callback error behavior
Edward Thomson 86a05ef3 2013-12-12T17:40:40 Validate struct versions in merge, revert
Russell Belfer 9cfce273 2013-12-12T12:11:38 Cleanups, renames, and leak fixes This renames git_vector_free_all to the better git_vector_free_deep and also contains a couple of memory leak fixes based on valgrind checks. The fixes are specifically: failure to free global dir path variables when not compiled with threading on and failure to free filters from the filter registry that had not be initialized fully.
Russell Belfer 26c1cb91 2013-12-09T09:44:03 One more rename/cleanup for callback err functions
Russell Belfer c7b3e1b3 2013-12-06T15:42:20 Some callback error check style cleanups I find this easier to read...
Russell Belfer 25e0b157 2013-12-06T15:07:57 Remove converting user error to GIT_EUSER This changes the behavior of callbacks so that the callback error code is not converted into GIT_EUSER and instead we propagate the return value through to the caller. Instead of using the giterr_capture and giterr_restore functions, we now rely on all functions to pass back the return value from a callback. To avoid having a return value with no error message, the user can call the public giterr_set_str or some such function to set an error message. There is a new helper 'giterr_set_callback' that functions can invoke after making a callback which ensures that some error message was set in case the callback did not set one. In places where the sign of the callback return value is meaningful (e.g. positive to skip, negative to abort), only the negative values are returned back to the caller, obviously, since the other values allow for continuing the loop. The hardest parts of this were in the checkout code where positive return values were overloaded as meaningful values for checkout. I fixed this by adding an output parameter to many of the internal checkout functions and removing the overload. This added some code, but it is probably a better implementation. There is some funkiness in the network code where user provided callbacks could be returning a positive or a negative value and we want to rely on that to cancel the loop. There are still a couple places where an user error might get turned into GIT_EUSER there, I think, though none exercised by the tests.
Russell Belfer fcd324c6 2013-12-06T15:04:31 Add git_vector_free_all There are a lot of places that we call git__free on each item in a vector and then call git_vector_free on the vector itself. This just wraps that up into one convenient helper function.
Russell Belfer dab89f9b 2013-12-04T21:22:57 Further EUSER and error propagation fixes This continues auditing all the places where GIT_EUSER is being returned and making sure to clear any existing error using the new giterr_user_cancel helper. As a result, places that relied on intercepting GIT_EUSER but having the old error preserved also needed to be cleaned up to correctly stash and then retrieve the actual error. Additionally, as I encountered places where error codes were not being propagated correctly, I tried to fix them up. A number of those fixes are included in the this commit as well.
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.

Rémi Duraffort c6451624 2013-07-15T16:00:07 Fix some more memory leaks in error path
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.
