2017-05-26Implement a custom deflate sink function for bspatchTianjie Xu1-58/+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. Test: recovery_component_test && apply an incremental update on angler Change-Id: I2274ec50a1607089abcc9d0954a2a748f28c3122
2017-05-16Print SHA1 of the patch if bsdiff fails with data errorTianjie Xu1-6/+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.

2017-03-28applypatch: Change the ssize_t length parameters to size_t.Tao Bao1-9/+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.

2017-03-16More cleanup to imgdiff & imgpatchTianjie Xu1-9/+16
Also remove the utils in applypatch and replace them with the corresponding libbase functions. Test: recovery tests pass. Change-Id: I77254c141bd3e7d3d6894c23b60e866009516f81
2017-02-02Use bspatch from external/bsdiff.Sen Jiang1-0/+3
Now ApplyBSDiffPatch() will stream the output to sink as we go instead of sinking everything at the end. Test: recovery_host_test Bug: 26982501 Change-Id: I05b6ed40d45e4b1b19ae72784cf705b731b976e3

2016-12-20Add tests for imgdiff.Tao Bao1-205/+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.

2016-10-15Change StringValue to use std::stringTianjie Xu1-22/+22
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
2016-06-14applypatch: Don't call inflate() when it expects zero-length output.Tao Bao1-57/+66
We may have expanded_len == 0 when calling inflate(). After switching to using std::vector, it passes a nullptr buffer to inflate() and leads to Z_STREAM_ERROR. Bug: 29312140 Change-Id: Iab7c6c07a9e8488e844e7cdda76d02bd60d2ea98

2016-03-03Fix the improper use of LOCAL_WHOLE_STATIC_LIBRARIES.Tao Bao1-1/+1
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.

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

2012-08-21add bonus data feature to imgdiff/imgpatch/applypatchDoug Zongker1-4/+17
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.

2010-02-23refactor applypatch and friendsDoug Zongker1-315/+170
Change the applypatch function to take meaningful arguments instead of argc and argv. Move all the parsing of arguments into main.c (for the standalone binary) and into install.c (for the updater function). applypatch() takes patches as Value objects, so we can pass in blobs extracted from the package without ever writing them to temp files. The patching code is changed to read the patch from memory instead of a file. A bunch of compiler warnings (mostly about signed vs unsigned types) are fixed. Support for the IMGDIFF1 format is dropped. (We've been generating IMGDIFF2 packages for some time now.) Change-Id: I217563c500012750f27110db821928a06211323f
2010-02-18relocate applypatch; add type system and new functions to edifyDoug Zongker1-0/+364
- 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
