2016-12-28imgdiff: Fix an edge case that leads to infinite loop.Tao Bao1-15/+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
2016-12-20Add tests for imgdiff.Tao Bao1-30/+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.

2016-11-16Use static_cast to cast pointers returned by malloc/calloc/realloc/mmap.Rahul Chaudhry1-16/+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).

2016-06-01Revert "Fix memory/resource handling in imgdiff.cpp, using unique_ptr and vector."Tao Bao1-38/+40
This reverts commit 50a6f8c8335be920833d06e5dabd37de279c98a9. A mix of new and free leads to memory corruptions.

Treat it as a normal chunk if inflate() fails. Test: run imgdiff on corrupted gzip and apply the patch Bug: 27153028 Change-Id: Idcbb3c1360ec0774e6c7861b21d99af8ee10604a

2015-12-23imgdiff: skip spurious gzip headers in image filesDavid Riley1-6/+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.

2012-08-21add bonus data feature to imgdiff/imgpatch/applypatchDoug Zongker1-8/+49
The bonus data option lets you give an additional blob of uncompressed data to be used when constructing a patch for chunk #1 of an image. The same blob must be available at patch time, and can be passed to the command-line applypatch tool (this feature is not accessible from edify scripts). This will be used to reduce the size of recovery-from-boot patches by storing parts of the recovery ramdisk (the UI images) on the system partition.

2010-02-18relocate applypatch; add type system and new functions to edifyDoug Zongker1-0/+1010
- Move applypatch to this package (from build). - Add a rudimentary type system to edify: instead of just returning a char*, functions now return a Value*, which is a struct that can carry different types of value (currently just STRING and BLOB). Convert all functions to this new scheme. - Change the one-argument form of package_extract_file to return a Value of the new BLOB type. - Add read_file() to load a local file and return a blob, and sha1_check() to test a blob (or string) against a set of possible sha1s. read_file() uses the file-loading code from applypatch so it can read MTD partitions as well. This is the start of better integration between applypatch and the rest of edify. b/2361316 - VZW Issue PP628: Continuous reset to Droid logo: framework-res.apk update failed (CR LIBtt59130) Change-Id: Ibd038074749a4d515de1f115c498c6c589ee91e5
