2017-03-07Refractor the code for imgdiffTianjie Xu2-618/+596
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

2017-01-19imgdiff: cache bsdiff suffix array in zip mode.Sen Jiang2-16/+20
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.

2016-12-20Add tests for imgdiff.Tao Bao6-266/+335
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.

2016-11-28Remove 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.

2016-11-21applypatch: Release FD when explicitly calling close.Tao Bao1-5/+5
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.

Applypatch_check should be skipped if no sha is specified. As the comments said: "It's okay to specify no sha1s; the check will pass if the LoadFileContents is successful. Useful for reading partitions, where the filename encodes the sha1s." Test: The update package applied on angler successfully. Bug: 32243751 Change-Id: Ib8f3dadf19f745c2dbd350d60da46ab12d75bc87

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
