2018-03-21	Added more unittests for invalid patch formats.	Alex Deymo
	This adds new unittests to cover more error cases in the parsing logic. Bug: None Test: Added more unittests. Change-Id: I897ae5e966fb6777d047855a72ff0a8489f4711f
2018-03-19	Handle more invalid patch header cases.	Alex Deymo
	Added more unittests for checking invalid headers. Bug: chromium:822821 Test: Added unittests Change-Id: I649674c41f00395dbf63f53e2576f7b7b61116c3
2018-01-18	Add an argument parser in bsdiff	Tianjie Xu
	Add a parser of format, type and quality in the bsdiff main function. This allow the bsdiff binary to choose between the BSDFF40\|BSDF2 patch format and compress the patch with desired algorithms. Bug: 34220646 Test: unittest pass; generate brotli compressed patches with bsdiff binary Change-Id: Ia4f7941e4eca7e6047e2749315127d1cf4a988ee
2017-11-17	Fix the bspatch failure on an empty brotli stream	Tianjie Xu
	When we close the BrotliDecompressor, we check for BrotliDecoderIsFinished(). This function may return false if we never call BrotliDecoderDecompressStream(), leading to a failure in bspatch in case of an empty brotli stream. This CL fixes the issue by checking BrotliDecoderIsUsed() along with IsFinished(). Since we have the compressed stream and the precomputed uncompressed size in the patch; we need these checks to avoid unexpected size mismatch. Bug: 69472150 Test: unittest pass Change-Id: Icf7b324836fa59fd3111ba91b03622215a0c8f5f
2017-11-16	Implement a new bsdiff format	Tianjie Xu
	Add a new BSDF2 format that allows compression of ctrl/diff/extra streams with different algorithms. The compression algorithm supported for now is bz2 and brotli. This new format is similar to the legacy "BSDIFF40" format except for the magic headers. File format: 0 8 magic header 8 8 X 16 8 Y 24 8 new_file_size 32 X compressed control block 32+X Y compressed diff block 32+X+Y ??? compressed extra block The magic header for BSDF2 format: 0 5 BSDF2 5 1 compressed type for control stream 6 1 compressed type for diff stream 7 1 compressed type for extra stream Bug: 34220646 Test: unittest pass Change-Id: I6eb0867e88476dbc4a4b7be609783f8c8a0a41cd
2017-10-26	Add an interface for bspatch reader	Tianjie Xu
	Add a wrapper class to separate the patch read from data stream decompression. Therefore, bspatch will be able to process the patch that is compressed with various tools. Test: unittest pass Change-Id: I5214e0451bde80366e8a70b960703afb2b2a7d97
