2017-08-02Refactor the imgdiffTianjie Xu1-1/+2
This helps us to add a new mode to handle large APKs in the follow up CL. Changes include: 1. Create a new interface class 'Image' 1. Create subclasses 'ZipModeImage' and 'ImageModeImage' and move the related functions there. Bug: 63542719 Test: recovery_component_test passes Change-Id: I7729b0ba39b19a9c84811636a60dd0a0b1acc2f0
2017-03-16More cleanup to imgdiff & imgpatchTianjie Xu1-9/+6
Also remove the utils in applypatch and replace them with the corresponding libbase functions. Test: recovery tests pass. Change-Id: I77254c141bd3e7d3d6894c23b60e866009516f81
2017-03-07Refractor the code for imgdiffTianjie Xu1-0/+3
Put ImageChunk and some helper functions into a class. Also switch to using std::vector instead of malloc. Bug: 18606652 Test: imgdiff_test passed on host. Also generate a complete incremental OTA package. The file content is the same and time consumption is similar. Change-Id: Id603ada4e130ef521218400761a119001a86ca79
2017-02-02Use bspatch from external/bsdiff.Sen Jiang1-0/+4
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
2017-01-20imgpatch: Compile with ZLIB_CONST defined.Tao Bao1-3/+9
So z_stream.next_in takes pointer to const data. Test: mmma bootable/recovery/applypatch Change-Id: If269b766a7c84fa2f67424ee61ba5afab0159261
2017-01-19imgdiff: cache bsdiff suffix array in zip mode.Sen Jiang1-3/+3
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
2016-12-28imgdiff: Fix an edge case that leads to infinite loop.Tao Bao1-0/+1
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 Bao1-21/+69
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.

2016-11-01applypatch: Add testcases for applypatch executable.Tao Bao1-5/+25
Refactor applypatch/main.cpp into libapplypatch_modes so that we can add testcases. Some changes to applypatch/main.cpp: - Replace char** argv with const char**; - Use android::base::Split() to split ":"; - Use android::base::ParseUInt(). Bug: 32383590 Test: Unit tests pass, install-recovery.sh works. Change-Id: I44e7bfa5ab717d439ea1d0ee9ddb7b2c40bb95a4
2016-10-18Replace minzip with libziparchiveTianjie Xu1-1/+0
Clean up the duplicated codes that handle the zip files in bootable/recovery; and rename the library of the remaining utility functions to libotautil. Test: Update package installed successfully on angler. Bug: 19472796 Change-Id: Iea8962fcf3004473cb0322b6bb3a9ea3ca7f679e
2016-09-30Turn on -Werror for recoveryTianjie Xu1-0/+5
Also remove the 0xff comparison when validating the bootloader message fields. As the fields won't be erased to 0xff after we remove the MTD support. Bug: 28202046 Test: The recovery folder compiles for aosp_x86-eng Change-Id: Ibb30ea1b2b28676fb08c7e92a1e5f7b6ef3247ab (cherry picked from commit 7aa88748f6ec4e53333d1a15747bc44826ccc410)

2016-03-03Fix the improper use of LOCAL_WHOLE_STATIC_LIBRARIES.Tao Bao1-20/+44
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.

2010-02-23refactor applypatch and friendsDoug Zongker1-0/+2
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/+59
- 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
