2017-11-16Switch imgdiff to libbase loggingTianjie Xu2-97/+109
Also add a verbose option. And we won't print messages of 'info' severity unless '-v' is present. Test: run imgdiff and check the logs. Change-Id: I1b90874baea8e72e2a2323a0b63bc5d35e653e6b
2017-11-10applypatch: Change the patch parameter to const Value& in Apply{BSDiff,Image}Patch.Tao Bao4-45/+47
It used to be "const Value*", but nullptr won't be a valid input. Test: recovery_host_test; recovery_component_test Change-Id: I904b5689ac3e64504088bf0544c9fb5d45a52243
2017-11-08Include bspatch.h from bsdiff/Alex Deymo1-1/+1
The function ApplyBSDiffPatch() defined in bspatch.cpp is declared in applypatch.h, but it includes "bspatch.h" from the bsdiff/ project, which is at least confusing. There is no "bspatch.h" in this repo, so the include actually reffers to the one in bsdiff. This patch uses the "bsdiff/bspatch.h" form instead to avoid confusion. Bug: None Test: It builds.

2017-11-03Switch to bionic gtest in bootable/recoveryTianjie Xu3-19/+17
We encountered segfaults in Imgdiff host tests due to the failure to reset states of getopt. The problem can be solved by switching to use bionic's gtest where a new process is forked for each test. Also modify the recovery_component_test to make sure it runs in parallel. Changes include: 1. Merge the writes to misc partition into one single test. 2. Change the hard coded location "/cache/saved.file" into a configurable variable. Bug: 67849209 Test: recovery tests pass Change-Id: I165d313f32b83393fb7922c5078636ac40b50bc2

2017-10-24Use SuffixArrayIndexInterface opaque type instead of the underlying data pointer.Alex Deymo2-7/+10
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

2017-10-09Revert "Revert "Move error_code.h into otautil.""Tao Bao1-0/+1
This reverts commit 26436d6d6010d5323349af7e119ff8f34f85c40c to re-land "Move error_code.h into otautil.". This way it stops requiring relative path ".." in LOCAL_C_INCLUDES (uncrypt and edify). Soong doesn't accept non-local ".." in "local_include_dirs". This CL needs to land with device-specific module changes (e.g. adding the dependency on libotautil).

2017-10-09applypatch: Forward declare struct Value.Tao Bao4-2/+8
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

2017-09-21Output split information for imgdiff when handling large apksTianjie Xu2-61/+134
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
2017-09-06Improve imgdiff for large zip filesTianjie Xu2-19/+480
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
2017-08-29Turn on -Wall for recovery modulesTianjie Xu1-3/+7
Turn on -Wall for all modules. Also remove the obsolete file_cmp() in apply_patch test and now() in wear_ui. The only exception is lib_edify due to the unused functions in the intermediate cpp files generated from the lex files. It will be handled in a seperate CL. Bug: 64939312 Test: mma, unit tests pass Change-Id: Ic53f76b60b6401ab20db3d98130d674c08e3702f
2017-08-19Move Image/ImageChunk/PatchChunk declaration into header filesTianjie Xu3-272/+319
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
2017-08-13Add a new PatchChunk class in imgdiffTianjie Xu1-236/+292
This way we can keep the input images const when calling genetatepatches(). Test: recovery component test; diff and patch on chrome.apk; generate recovery-from-boot.p for angler. Change-Id: I65b5689b88f6719c6ede46bb82def0c4caeb8a61
2017-08-02Refactor the imgdiffTianjie Xu2-393/+569
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
2017-07-07Fix a rare failure for imgdiff when random data equals gzip headerTianjie Xu1-11/+14
In a rare case, a random chunk will pass both the gzip header check and the inflation process; but fail the uncompressed length check in the footer. This leads to a imgdiff failure. So, we should treat this chunk as 'normal' instead of 'inflated' while generating the patch. Bug: 63334984 Test: imgdiff generates patch successfully on previous failing images. Change-Id: Ice84f22d3653bce9756bda91e70528c0d2f264a0
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 Xu3-22/+32
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.

2017-04-26applypatch: Remove the obsolete support for "applypatch -s".Tao Bao1-17/+1
The SpaceMode (applypatch -s) was used in amend script (cupcake) only, which has been removed since commit 9ce2ebf5d300eba5f6086583b0941ef68a3e4b42 (platform/build). The later (and current) edify script uses apply_patch_space(). Note that other modes (PatchMode, CheckMode) of applypatch executable are mostly used by install-recovery.sh script.

2017-03-28applypatch: Change the ssize_t length parameters to size_t.Tao Bao5-47/+40
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.

Factor out libimgdiff static library for testing purpose. This CL adds the imgdiff tests on host and on target both (similar to libimgpatch).

2016-11-28Remove ota_close(int) and ota_fclose(FILE*).Tao Bao1-2/+2
We should always use unique_fd or unique_file to hold the FD or FILE* pointer when opening via ota_(f)open functions. This CL avoids accidentally closing raw FDs or FILE* pointers that are managed by unique_fd/unique_file. Test: recovery_component_test passes. Change-Id: If58eb8b5c5da507563f85efd5d56276472a1c957
2016-11-23Add ota_close(unique_fd&) and ota_fclose(std::unique_ptr<FILE>&).Tao Bao1-7/+7
We were using the below sequence prior to the CL in [1]. unique_fd fd(ota_open(...)); ota_close(fd); fd.reset(ota_open(...)); fd.reset() may unintentionally close the newly opened FD if it has the same value as the early ota_open. The CL in [1] changed to "ota_close(fd.release())" to avoid the issue. This CL adds a new overloaded function ota_close(unique_fd&) to handle the release automatically. Similarly add ota_fclose(std::unique_ptr<FILE>&). [1] commit 48cf770471ef53fbf0a1837196220862a0bdb18d. Bug: 33034669 Test: recovery_component_test passes.

We use android::base::unique_fd() to avoid leaking FD. We also want to call close (or ota_close) to explicitly check the close result. When combining the two together, we need to release the unique_fd to avoid closing the same FD twice. Bug: 33034669 Test: Trigger applypatch with install-recovery.sh.

2013-12-20fix unnecessarily slow writing of EMMC partitionsDoug Zongker1-15/+3
These were attempts to write partitions "conservatively" in hopes of fixing the problems with writing the radio partition on Nexus 4. They didn't work (a kernel patch was needed), but got left in. They make writing of partitions unnecessarily slow (ie, we really shouldn't need to sync() after every 4kb). Roll back most of them, but leave the verification read-back in.

2013-07-10recovery: try to write EMMC partitions more reliablyDoug Zongker2-7/+73
Nexus 4 has flash errors that manifest during large writes (eg, of the radio partition). Writes of some blocks seem to be dropped silently, without any errors being returned to the user level. Make two changes to the partition-writing code: - break it up into 1MB writes instead of writing partitions with a single fwrite() call. Pause for 50ms in between every chunk. - read the partition back after writing and verify that we read what we wrote. Drop caches before reading so we (hopefully) are reading off the actual flash and not some cache. Neither of these should be necessary.

2012-08-21add bonus data feature to imgdiff/imgpatch/applypatchDoug Zongker5-21/+99
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 Zongker9-1256/+1185
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 Zongker17-0/+3882
- 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
