2019-07-31Simulator: add the argument to keep the updated imagesTianjie Xu1-1/+3
Add the command line option to select the work directory and save the updated image files. Because some people might have interested in getting updated images from an ota file. Also, fix a minor issue that the destination of package_extract_file needs to be updated if it's a block device. Otherwise, an unintended file may be extracted in the callers' directory. Test: run simulation, run unit tests Change-Id: Ic6a7db0580bc1748d6e080102e4654da4e41fd8c
2019-07-16Add command line parser for simulatorTianjie Xu1-0/+9
Add a command line parser. Also add the support to parse the oem property file and skip certain functions. Bug: 131911365 Test: run simulator for wear builds Change-Id: Ide306b53d3f42b29c02279969aeb18bec4045d6f
2019-07-08Add a GetMappedPackageLength to UpdaterRobin Lee1-1/+3
Corresponds to GetMappedPackageAddress. There is at least one custom device recovery with an extension to copy the package somewhere else as a backup. Ability to do this was removed in change ag/955273. Test: lunch cf_x86_tv-eng; make Test: atest recovery_unit_test recovery_component_test Change-Id: I0e61d8a8839c47721874526504ea03b9ca7bafa9
2019-06-24Implement updater runtime for dynamic partitionsTianjie Xu2-0/+9
The simulator skips executing the operations for dynamic partitions, and will use the logical images under target_files/IMAGES directly. (Similar to the targets without DAP enabled) Bug: 131911365 Test: run update on cuttlefish, run simulator Change-Id: Id318d97ece4560df9f20dc5cabeb8b2e261bdf9c
2019-06-01Implement the TargetFile and BuildInfoTianjie Xu3-12/+110
The TargetFile class parses a target-file and provides functions to read its contents. And the BuildInfo tries to simulate the device with files on host. Some work it does includes parsing the build properties, and extracting the image files for partitions specified in the fstab. Bug: 131911365 Test: unit tests pass, run simulator with cuttlefish, wear devices and from extracted TF. Change-Id: Iefe4a96d619d2e4b3d038e31480f11a0f9a70afa
2019-05-29Implement an update simulator to verify BB OTA packages on hostTianjie Xu2-0/+94
Implement the simulator runtime and build the updater simulator as a host executable. The code to parse the target-files and mocks the block devices will be submitted in the follow-up. Bug: 131911365 Test: unit tests pass Change-Id: Ib1ba939aec8333ca68a45139514d772ad7a27ad8
2019-05-22Some clean ups to the updaterTianjie Xu2-5/+0
Remove some unnecessary includes or forward declarations. And include the correct headers to build host executables. Bug: 131911365 Test: unit tests pass Change-Id: I62e75f60678159fe24619a4bd386b1416f1a5b5d
2019-05-21Add UpdaterRuntime classTianjie Xu2-15/+83
This class adds a wrapper to the runtime dependent functions. Therefore, the behavior of update on device stays the same, while simulators can have their own implementations. Also change the caller side of the registered updater functions to call these runtime wrappers. Bug: 131911365 Test: unit tests pass, sideload an update on cuttlefish Change-Id: Ib3ab67132991d67fc132f27120e4152439d16ac5
2019-05-09Add Updater class and remove UpdaterInfoTianjie Xu2-22/+66
The UpdaterInfo class is merely a collection of pointers and POD types. We can replace it with a Updater class that has the ownership of the resources. This also makes this class extensible as we plan to add more functionality in the host simulator. Bug: 131911365 Test: unit tests pass, run an update on cuttlefish and check last_install Change-Id: I07ca5963bbee8ae3cb85ccc184464910aa73d4e4
2019-01-14updater: add functions to modify dynamic partition metadataYifan Hong2-0/+40
Test: sideload full OTA on cuttlefish Test: sideload incremental OTA on cuttlefish (that grows system, shrinks vendor, and move vendor to group foo) Test: verify that /cache/recovery/cc46ebfd04058569d0c6c1431c6af6c1328458e4 exists (sha1sum of "system") Bug: 111801737 Change-Id: Ibdf6565bc1b60f3665c01739b4c95a85f0261ae5
2018-08-17updater: Add TransferList class.Tao Bao1-0/+67
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
2018-08-16updater: Add SourceInfo::{ReadAll,DumpBuffer,Overlaps}.Tao Bao1-0/+26
Bug: 112151972 Test: Run recovery_unit_test on marlin. Change-Id: Ica2a7b3c768f5d8ca5d591a9560bca9f8ed847c5
2018-08-14Add the hash_tree_info class in CommandTianjie Xu1-0/+52
Add hash_tree_info to represent the hash tree computation arguments in the transfer commands 'compute_hash_tree'. Also add its parsing code in the Command class. Bug: 25170618 Test: unit tests pass Change-Id: Ie8607968377968e8fb3e58d1af0b8ca315e145be
2018-08-06Add an updater function to compute hash treeTianjie Xu1-0/+5
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
2018-07-07updater: Add ABORT command.Tao Bao1-0/+12
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. Test: recovery_unit_test and recovery_component_test on marlin. Change-Id: I47c41c423e62c41cc8515fd92f3c5959be08da02
2018-06-25updater: Add Command parsing codes.Tao Bao1-6/+284
The added codes are not used in the updater yet. The switch will happen in subsequent CLs. Test: Run recovery_unit_test and recovery_component_test on marlin. Change-Id: I1ae8a233280f02c2171b43ef028bdccdacb39c59
2018-05-26updater: Add Commmand class to manage BBOTA commands.Tao Bao1-0/+35
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. Change-Id: Ife202398a7660b152d84a3ba17b90f93d19c55f2
2018-02-28Add a singleton CacheLocation to replace the hard coded locationsTianjie Xu1-1/+0
This class allows us to set the following locations dynamically: cache_temp_source, last_command_file, stash_directory_base. In the updater's main function, we reset the values of these variables to their default locations in /cache; while we can set them to temp files in unit tests or host simulation. Test: unit tests pass Change-Id: I528652650caa41373617ab055d41b1f1a4ec0f87
2018-02-07Log the last command to cacheTianjie Xu1-0/+3
When performing an update, save the index and cmdline of the current command into the last command file if this command writes to the stash either explicitly of implicitly. This mitigates the overhead to update the last command file for every command. I ran a simple test on angler and the time to update 1000 times is ~2.3 seconds. Upon resuming an update, read the saved index first; then 1. In verification mode, check if all commands before the saved index have already produced the expected target blocks. If not, delete the last command file so that we will later resume the update from the start of the transfer list. 2. In update mode, skip all commands before the saved index. Therefore, we can avoid deleting stashes with duplicate id unintentionally; and also speed up the update. If an update succeeds or is unresumable, delete the last command file. Bug: 69858743 Test: Unittest passed, apply a failed update with invalid cmd on angler and check the last_command content, apply a failed update with invalid source hash and last_command is deleted. Change-Id: Ib60ba1e3c6d111d9f33097759b17dbcef97a37bf
2017-08-19Move Image/ImageChunk/PatchChunk declaration into header filesTianjie Xu1-278/+0
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
2017-08-01Add implemention of SortedRangeSetTianjie Xu1-1/+115
This is useful in imgdiff to maintain the block ranges of splitted source image. Bug: 34220646 Test: mma && unit tests pass Change-Id: I6427f2ea50f0e3b0aa3dd01880ec0206679b7429
2017-04-03Change the internal representation in RangeSet.Tao Bao1-28/+97
This CL makes the following changes to RangeSet: - Uses std::pair<size_t, size_t> to represent a Range; - Uses std::vector<Range> to represent a RangeSet; - Provides const iterators (forward and reverse); - Provides const accessor; - 'blocks()' returns the number of blocks (formerly 'size'); - 'size()' returns the number of Range's (formerly 'count'). Test: recovery_unit_test Test: Apply an incremental update with the new updater. Change-Id: Ia1fbb343370a152e1f7aa050cf914c2da09b1396
2017-03-31Move parse_range() and range_overlaps() into RangeSet.Tao Bao1-0/+95
Also move RangeSet into a header file to make it testable, and add unit tests. In RangeSet::Parse() (the former parse_range()), use libbase logging to do assertions. This has the same effect as the previous exit(EXIT_FAILURE) to terminate the updater process and abort an update. The difference lies in the exit status code (i.e. WEXITSTATUS(status) in install.cpp), which changes from 1 (i.e. EXIT_FAILURE) to 0. Test: recovery_unit_test Test: Apply an incremental update with the new updater. Change-Id: Ie8393c78b0d8ae0fd5f0ca0646d871308d71fff0
2016-10-18Replace minzip with libziparchiveTianjie Xu1-2/+2
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
2016-10-11Refactor libupdater into a seperate module.Tao Bao3-0/+85
So that we can write native tests for updater functions. This CL adds a testcase for getprop() function. Test: mmma bootable/recovery; Run recovery_component_test on device. Change-Id: Iff4c1ff63c5c71aded2f9686fed6b71cc298c228
