* Convert deflate image chunks to raw if the raw data is smallerTianjie Xu2018-05-241-0/+1
| | | | | | | | | | | | | | | | | The imgpatch will fail on empty deflates because the bspatch won't call the sink function if the target length is zero. Instead of compressing an empty string, it's cleaner to not generate such empty deflate chunks in the patch. Therefore, we can just convert the chunk type to raw if the target length is smaller than the patch data. Also adjust some unit tests and add the testdata gzipped_source & gzipped_target. These two files are ~1K each and are generated by gzipping two slightly different regular files. Bug: 79265132 Test: unit tests pass, imgpatch applys successfully on the given src/tgt Change-Id: I6bfff3251918137f6762a6f9e9551642371a1124
* Save the target file when applypatch tests failTianjie Xu2018-04-271-14/+10
| | | | | | | | | | | | | Save the target file to tempfile upon unittest failures so that we can try to decompress the deflate chunks in the flaky unittests. And print the zlib version in case that gets changed. Also the SHA1 of the uncompressed data seems correct; so only keep the final SHA1 to double confirm.

* Dump the uncompressed data's SHA1 to debug flaky testsTianjie Xu2018-04-261-1/+23
| | | | | | | | | | | | | | | Dump the SHA1 of the uncompressed data in applypatch to confirm if we are at least doing the bspatch part correctly. (I expect so since the actual length of the uncompressed data matches the expected length). Also try to decompress the deflate chunk inside the recovery image for these two flacky tests. In theory, there shouldn't be randomness in zlib; so we would know if we process the data wrongly if the deflate fails to decompress.

* Dump debug information for apply_patch unit testsTianjie Xu2018-04-241-0/+5
| | | | | | | | | | | | | The apply patch test should have a deterministic way to append patch data. Add debug logs to dump the length and SHA1 of each step to further track down the flakiness. Also redirect the debug logging to stdout in case the logcat becomes too chatty. Bug: 67849209 Test: Run recovery_component_test Change-Id: I42bafef2d9dee599719ae57840b3d8c00d243ebd

* applypatch: Forward declare struct Value.Tao Bao2017-10-091-0/+2
| | | | | | | | | | | | | And move '#include "edify/expr.h"' into .cpp files. This breaks the transitive dependency on libedify. Modules that include "applypatch/applypatch.h" don't need to add libedify into their dependency list, unless they really need anything from libedify. Build libedify static library for host, which is needed by libimgpatch. Test: mmma bootable/recovery Change-Id: Ibb53d322579fcbf593438d058d9bcee240625941
* Implement a custom deflate sink function for bspatchTianjie Xu2017-05-261-58/+86
| | | | | | | | | This new sink function works as a wrapper of the old sink. It deflates the available patch data on the fly. Therefore, we don't need to store the full uncompressed patch data in memory.

* Print SHA1 of the patch if bsdiff fails with data errorTianjie Xu2017-05-161-6/+8
| | | | | | | | | | | | | | 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.

* applypatch: Change the ssize_t length parameters to size_t.Tao Bao2017-03-281-9/+8
| | | | | | | | | | | | | | | | | 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.

* Add tests for imgdiff.Tao Bao2016-12-201-205/+200
| | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | If two libraries both use LOCAL_WHOLE_STATIC_LIBRARIES and include a same library, there would be linking errors when generating a shared library (or executable) that depends on the two libraries both. Also clean up Android.mk files. Remove the "LOCAL_MODULE_TAGS := eng" line for the updater module. The module will then default to "optional" which won't be built until needed.
