* updater: Add TransferList class.Tao Bao2018-08-171-0/+56
| | | | | | | | | This would be the top-level class that represents and holds the info parsed from a transfer list file. Bug: 112151972 Test: Run recovery_unit_test and recovery_component_test on marlin. Change-Id: I83b54df9d1411542eeeb8ef4a2db167e97f989c3

| * Add an updater function to compute hash treeTianjie Xu2018-08-061-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new command is part of the transfer.list and allows us to compute the hash tree on non-ab devices. The required arguments for the hash_tree computation are: hash_tree_ranges source_ranges hash_algorithm salt_hex root_hash Bug: 25170618 Test: unit tests pass; run simulator with compute_hash_tree Change-Id: I8ff0d582cc8adabb8a060db7845f38b35b28e62c
* | recovery: Add ability to interrupt UIJerry Zhang2018-07-301-1/+38
|/ | | | | | | | | | | | | | Normally calling a UI method will block indefinitely until the UI is actually used. This creates a method to interrupt the UI, causing waitKey to return -2. This in turn, will cause ShowMenu to return -2. This allows switching between recovery and fastbootd via usb commands. Test: adb shell /data/nativetest64/recovery_unit_test/recovery_unit_test Bug: 78793464 Change-Id: I4c6c9aa18d79070877841a5c9818acf723fa6096
* Fix the arguments passed to getopt_long(3).Tao Bao2018-07-171-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | The getopt_long(3) implementation in Android (upstream freebsd) expects a null-terminated array while parsing long options with required args. if (long_options[match].has_arg == required_argument) { optarg = nargv[optind++]; } ... if (long_options[match].has_arg == required_argument && optarg == NULL) { return (BADARG); } This seems to make sense in practice, as getopt(3) takes the first two arguments of argc and argv that are "as passed to the main() function on program invocation", and both of C and C++ spec say "the value of argv[argc] shall be 0". Prior to the CL, we may run into undefined behavior on malformed input command line (e.g. missing arg for an option that requires one). This CL fixes the issue by always appending a nullptr to the argument list (but without counting that into argc). Test: Build and boot into recovery with commands.

* tests: Clean up the temporary dirs post-run.Tao Bao2018-07-122-21/+22
| | | | | | | | | | TemporaryDir only deletes empty dirs (not done by its dtor because it tries to keep the temporary files available on error exit). Also change FreeCacheTest::MockFreeSpaceChecker to be static. Test: Run recovery_unit_test on marlin. Check /data/local/tmp post-run. Change-Id: I1bd54eb840e3094b4f22ee84c059eec2998773bf
* applypatch: Fix the return type of FreeSpaceForFile().Tao Bao2018-07-121-6/+18
| | | | | | | | | | | | | | Prior to this CL, FreeSpaceForFile() was returning `size_t`, which may overflow on ILP32 when called on a partition with 4GiB+ free space. Additionally, it was returning static_cast<size_t>(-1) on error, but the caller in freecache.cpp didn't check for that. This CL changes its return type to `int64_t`, and moves the function into freecache.cpp since there's no external caller. Test: Run recovery_unit_test on marlin. Test: Code search shows no external user of FreeSpaceForFile(). Change-Id: I00f501a057726e1f1ab69f367c46c77b30f2d774
* applypatch: Restrict applypatch_check to eMMC targets.Tao Bao2018-07-101-85/+47
| | | | | | | | | | | | | | | | | | | | | | | Also fix an error-pone behavior in previous code when verifying an eMMC target. As long as it loads the partition content successfully according to the SHAs embedded in the filename, it shouldn't further check against the SHAs given in the second argument. Because the loaded contents relate to a specific partition size. For example: apply_patch_check( "EMMC:/boot.img:src_size:src_hash:tgt_size:tgt_hash", "src_hash"); Assume "/boot.img" already has the desired hash of "tgt_hash", the previous code would give wrong verification result. The issue can be addressed by additionally listing "tgt_hash" as one of the desired SHAs (or by applying this CL). Bug: 110106408 Test: Run recovery_unit_test and recovery_component_test on marlin.

* updater: Add ABORT command.Tao Bao2018-07-071-0/+24
| | | | | | | | | | | This will be used for testing purpose only, replacing the previously used "fail", to intentionally abort an update. As we're separating the logic between commands parsing and execution, "abort" needs to be considered as a valid command during the parsing.

* tests: Skip ScreenRecoveryUITest on gr_init failure.Tao Bao2018-06-141-1/+38
| | | | | | | | | | | | | | | | | It addresses the ScreenRecoveryUITest failures on gce targets which don't have any graphics backend. Probing for all backend devices in tests could work, but would duplicate codes. This CL relies on the result of gr_init(). As a side effect, it may give false negatives if gr_init() is supposed to work but silently broken. But such issues are beyond ScreenRecoveryUITest's concern, which should be captured by the tests for minui or graphics backends instead. Fixes: 79616356 Test: Run recovery_unit_test on marlin.

* tests: Specify the death test style to avoid flakiness.Tao Bao2018-06-052-0/+5
| | | | | | | | | | | | | | | | | | | As warned below (while running the test), the default death test style (i.e. "fast") doesn't work well in a threaded context, which causes test flakiness (timeout or early exit). [WARNING] external/googletest/googletest/src/gtest-death-test.cc:836:: Death tests use fork(), which is unsafe particularly in a threaded context. For this test, Google Test detected 3 threads.

* | updater: Add Commmand class to manage BBOTA commands.Tao Bao2018-05-261-0/+37
|/ | | | | | | | | | | | Move the commands map parsing out of PerformBlockImageUpdate(), as this can be done more easily by the caller. The goal (not done in this CL) is to decouple command parsing logic from the performers. This allows (a) focusing on the command logic in the performer; and (b) extending BBOTA commands syntax separately. Test: Run recovery_unit_test and recovery_component_test.

* screen_ui: Fix an issue in RTL locale detection.Tao Bao2018-05-091-1/+1
| | | | | | | | | | | | | | | | The CL in [1] moved android.os.RecoverySystem to send the locale argument in well-formed BCP 47 language tags (e.g. "en-US" instead of "en_US"), with the matching changes to recovery code in [2]. However, the one in ScreenRecoveryUI::SetLocale() was missed, which broke RTL locale detection when using new format. [1] commit 38715228 in platform/frameworks/base [2] commit 2078b22e in platform/bootable/recovery Test: Set the locale to "ar-EG". `Run graphics test` under recovery. Check the progress bar.

* tests: Add tests for ScreenRecoveryUI.Tao Bao2018-05-091-0/+167
| | | | | | | | | | | | In order to support that, this CL adds Paths::set_resource_dir() to override the default resource dir ("/res/images/") that's only available under recovery. Note that since there're external modules depending on libminui, it adds a separate function of res_set_resource_dir(), instead of requiring the dependency on libotautil for everyone.

* otautil: Remove the aborts in RangeSet::Parse().Tao Bao2017-11-071-14/+64
| | | | | | | | | | | | | | | | | | | We used to CHECK and abort on parsing errors. While it works fine for the updater use case (because recovery starts updater in a forked process and collects the process exit code), it's difficult for other clients to use RangeSet as a library (e.g. update_verifier). This CL switches the aborts to returning empty RangeSet instead. Callers need to check the parsing results explicitly. The CL also separates RangeSet::PushBack() into a function, and moves SortedRangeSet::Clear() into RangeSet. Test: recovery_unit_test Test: Sideload an OTA package with the new updater on angler.

* Fix matches_locale functionTianjie Xu2016-04-201-0/+29
| | | | | | | | | matches_locale was expecting input locale string to have at most one underscore; as a result "zh_CN_#Hans" ignores "zh_CN" and matches into "zh". Fix the match function and add unit tests. Bug: 27837319 Change-Id: I4e8a66f91cae6ac2a46b6bf21f670d5ea564c7c8
* recovery: use __android_log_pmsg_file_write for log filesMark Salyzyn2016-03-311-0/+92
| | | | | | | | | | | | | | | | | | | | | | | | | (cherry-pick from commit a4f701af93a5a739f34823cde0c493dfbc63537a) - Add call to __android_log_pmsg_file_write for recovery logging. - Add call to refresh pmsg if we reboot back into recovery and then allow overwrite of those logs. - Add a new one-time executable recovery-refresh that refreshes pmsg in post-fs phase of init. We rely on pmsg eventually scrolling off to age the content after recovery-persist has done its job. - Add a new one-time executable recovery-persist that transfers from pmsg to /data/misc/recovery/ directory if /cache is not mounted in post-fs-data phase of init. - Build and appropriately trigger the above two as required if BOARD_CACHEIMAGE_PARTITION_SIZE is undefined. - Add some simple unit tests NB: Test failure is expected on systems that do not deliver either the recovery-persist or recovery-refresh executables, e.g. systems with /cache. Tests also require a timely reboot sequence of test to truly verify, tests provide guidance on stderr to direct. Bug: 27176738 Change-Id: I17bb95980234984f6b2087fd5941b0a3126b706b
