There were some confusing issues mixing up the number of bytes
written to the zstream output buffer with the number of bytes
consumed from the zstream input. This reorganizes the zstream
API and makes it easier to deflate an arbitrarily large input
while still using a fixed size output.
This removes the fetchRecurse compiler warnings and makes the
behavior match the other submodule options (i.e. the in-memory
setting can be reset to the on-disk value).
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.
This moves the expected and actual test data along with the source
data for the userdiff tests into the tests/resources/userdiff test
repo and updates the test to use that.
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.
Don't try to determine whether the system supports file modes
when putting the tree data in the index during checkout. The tree's
mode is canonical and did not come from stat(2) in the first place.
It's hard or even impossible to correctly free the string buffer
allocated by git_patch_to_str in some circumstances. Drop the function
so people have to use git_patch_to_buf instead - git_buf has a dedicated
destructor.
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.
