* imgdiff: cache bsdiff suffix array in zip mode.Sen Jiang2017-01-191-13/+17
| | | | | | | | | | | In zip mode, if a chunk is not deflate or its filename can't be found in source chunks, the entire source file is used as old data for bsdiff, To avoid repeatedly construct the suffix array used by bsdiff, we cache the suffix array of the entire source file. Bug: 34281147 Test: =time -v imgdiff -z Chrome-ORF74B.apk Chrome-ORF76B.apk Chrome.imgdiff Change-Id: Ifd957ccecf7226fcb44dbf28c58969a06ef74f4b
* imgdiff: Fix an edge case that leads to infinite loop.Tao Bao2016-12-281-15/+10
| | | | | | | | | 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 Bao2016-12-201-30/+24
| | | | | | | | | | | | 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.

* | Use static_cast to cast pointers returned by malloc/calloc/realloc/mmap.Rahul Chaudhry2016-11-161-16/+16
|/ | | | | | | | | | | static_cast is preferable to reinterpret_cast when casting from void* pointers returned by malloc/calloc/realloc/mmap calls. Discovered while looking at compiler warnings (b/26936282).

* imgdiff: skip spurious gzip headers in image filesDavid Riley2015-12-231-6/+13
| | | | | | | | | | | | | dragon kernel is compressed via lz4 for boot speed and bootloader support reasons and recent prebuilts happen to include the gzip header sequence which is causing imgdiff to fail. Detect a spurious gzip header and treat the section as a normal section.
