*	Fix a rare failure for imgdiff when random data equals gzip header	Tianjie Xu	2017-07-07	1	-0/+33
\| \| \| \| \| \| \| \| \| \| \|	In a rare case, a random chunk will pass both the gzip header check and the inflation process; but fail the uncompressed length check in the footer. This leads to a imgdiff failure. So, we should treat this chunk as 'normal' instead of 'inflated' while generating the patch. Bug: 63334984 Test: imgdiff generates patch successfully on previous failing images. Change-Id: Ice84f22d3653bce9756bda91e70528c0d2f264a0
*	Print SHA1 of the patch if bsdiff fails with data error	Tianjie Xu	2017-05-16	1	-0/+39
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	This will help us to identify the patch corruption. Meanwhile fix a wrong size parameter passed to bspatch. (patch->data.size() into patch->data.size() - patch_offset). Also remove the only usage of "ApplyBSDiffPatchMem()" and inline its Sink function for simplicity. Bug: 37855643 Test: Prints SHA1 for corrupted patch in imgdiff_test. Change-Id: Ibf2db8c08b0ded1409bb7c91a3547a6bf99c601d
*	applypatch: Let Apply{BSDiff,Image}Patch accept std::function.	Tao Bao	2017-03-28	1	-56/+24

*	applypatch: Change the ssize_t length parameters to size_t.	Tao Bao	2017-03-28	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Mostly for applypatch family APIs like ApplyBSDiffPatch() and ApplyImagePatch(). Changing to size_t doesn't indicate they would necessarily work with very large size_t (e.g. > ssize_t), just similar to write(2). But otherwise accepting negative length doesn't make much sense. Also change the return type of SinkFn from ssize_t to size_t. Callers tell a successful sink by comparing the number of written bytes against the desired value. Negative return values like -1 are not needed. This also makes it consistent with bsdiff::bspatch interface. Test: recovery_component_test Test: Apply an incremental with the new updater.

*	More cleanup to imgdiff & imgpatch	Tianjie Xu	2017-03-16	1	-4/+5
\| \| \| \| \| \| \| \|	Also remove the utils in applypatch and replace them with the corresponding libbase functions. Test: recovery tests pass. Change-Id: I77254c141bd3e7d3d6894c23b60e866009516f81
*	Refractor the code for imgdiff	Tianjie Xu	2017-03-07	1	-0/+56
\| \| \| \| \| \| \| \| \| \| \|	Put ImageChunk and some helper functions into a class. Also switch to using std::vector instead of malloc. Bug: 18606652 Test: imgdiff_test passed on host. Also generate a complete incremental OTA package. The file content is the same and time consumption is similar. Change-Id: Id603ada4e130ef521218400761a119001a86ca79
*	imgdiff: Fix an edge case that leads to infinite loop.	Tao Bao	2016-12-28	1	-0/+80
\| \| \| \| \| \| \| \| \|	When the input image ends with the magic value sequence of 0x1f, 0x8b, 0x0b (optionally with 0x00), the image parsing code will be stuck in an infinite loop. Test: recovery_component_test passes. Change-Id: Ie3629dfdc41360387b19cc3e0359c95ae4fb998e
*	Add tests for imgdiff.	Tao Bao	2016-12-20	1	-0/+448
	Factor out libimgdiff static library for testing purpose. This CL adds the imgdiff tests on host and on target both (similar to libimgpatch). In practice, we only need imgdiff binary on host, and libimgpatch on target. But they should build and pass tests on both platforms. Test: recovery_host_test passes; recovery_component_test passes.
