| * Use SuffixArrayIndexInterface opaque type instead of the underlying data pointer.Alex Deymo2017-10-241-2/+3
| | | | | | | | | | | | | | | | | | | | | | bsdiff interface is changing such that it hides the suffix array pointer from the public interface. This allows to use a different suffix array data size depending on the input size, running much faster in the normal case. Bug: 34220646 Test: `make checkbuild`; Ran an incremental update generation on a non-A/B device. Change-Id: I78e766da56cf28bc7774b8c8e58527bc11d919fb

|/ | | | | | | | | Also drop the "bootable/recovery" path in LOCAL_C_INCLUDES from applypatch modules. Test: lunch aosp_{angler,bullhead,fugu,dragon,sailfish}-userdebug; mmma bootable/recovery Change-Id: Idd602a796894f971ee4f8fa3eafe36c42d9de986
* applypatch: Forward declare struct Value.Tao Bao2017-10-091-1/+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
* Output split information for imgdiff when handling large apksTianjie Xu2017-09-211-1/+5
| | | | | | | | | | | Add a mandatory option in imgdiff to write the split info (i.e. patch_size, tgt_size, src_ranges) to file when handling large apks. Therefore, the caller of imgdiff can create split transfers based on the info. Bug: 63542719 Test: unit tests pass Change-Id: I853d55d1f999fd576474faa81077f7307f4d856d
* Improve imgdiff for large zip filesTianjie Xu2017-09-061-1/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to the cache size limit for OTA generation, we used to split large zip files linearly into pieces and do bsdiff on them. As a result, i) we lose the advantage of imgdiff; ii) if there's an accidental order change of some huge files inside the zip, we'll create an insanely large patch. This patch splits the src&tgt more smartly based on the zip entry_name. If the entry_name is empty or no matching source is found for a target chunk, we'll skip adding its source and later do a bsdiff against the whole split source image (this rarely happens in our use cases except for the metadata inside a ziparchive). After the split, the target pieces are continuous and block aligned, while the sources pieces are mutually exclusive. (Some of the source blocks may not be used if there's no matching entry_name in the target.) Then we will generate patches accordingly between each split image pairs. Afterwards, if we apply imgpatch to each pair of split source/target images and add up the patched result, we can get back the original target image. For example: Input: [src_image, tgt_image] Split: [src-0,tgt-0; src-1,tgt-1, src-2,tgt-2] Diff: [ patch-0; patch-1; patch-2] Patch: [(src-0,patch-0)=tgt-0; (src-1,patch-1)=tgt-1; (src-2,patch-2)=tgt-2;] Append: [tgt-0 + tgt-1 + tgt-2 = tgt_image] Peformance: For the small package in b/34220646, we decrease the patch size of chrome.apk dramatically from 30M to 400K due to the order change of two big .so files. On two versions of angler, I also observe decent patch size decrease. For chrome.apk, we reduced the size from 5.9M to 3.2M; and for vevlet.apk from 8.0M to 6.5M. Bug: 34220646 Test: recovery component test && apply imgdiff & imgpatch on two chrome.apk Change-Id: I145d802984fa805efbbac9d01a2e64d82ef9728b
* Move Image/ImageChunk/PatchChunk declaration into header filesTianjie Xu2017-08-191-0/+247
| | | | | | | | | 1. Move the declaration of the Image classes to the header file to make testing easier. 2. Also move rangeset.h to bootable/recovery to allow access in imgdiff. Test: recovery component test Change-Id: I68a863e60a3f2e7ae46ee48f48eb15391f5f4330
* Print SHA1 of the patch if bsdiff fails with data errorTianjie Xu2017-05-161-2/+0
| | | | | | | | | | | | | | 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 Bao2017-03-282-15/+10
| | | | | | | | | | | | | | | | | 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 Bao2016-12-202-4/+45
| | | | | | | | | | | | 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.

* Change StringValue to use std::stringTianjie Xu2016-10-151-6/+4
| | | | | | | | | | | Changing the field of 'Value' in edify to std::string from char*. Meanwhile cleaning up the users of 'Value' and switching them to cpp style. Test: compontent tests passed. Bug: 31713288 Change-Id: Iec5a7d601b1e4ca40935bf1c70d325dafecec235
* Fix the improper use of LOCAL_WHOLE_STATIC_LIBRARIES.Tao Bao2016-03-031-0/+87
| | | | | | | | | | | | | 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.

* applypatch: Compile libimgpatch for target and host.Sen Jiang2016-01-281-0/+26
update_engine need it for the new IMGDIFF operation. Also removed __unused in ApplyImagePatch() as I got error building it for the host, and I think it's dangerous not checking the size of the input. Test: mma Bug: 26628339 Change-Id: I22d4cd55c2c3f87697d6afdf10e8106fef7d1a9c
