* Add Updater class and remove UpdaterInfoTianjie Xu2019-05-092-22/+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
* updater: add functions to modify dynamic partition metadataYifan Hong2019-01-142-0/+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
* updater: Add TransferList class.Tao Bao2018-08-171-0/+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
* updater: Add SourceInfo::{ReadAll,DumpBuffer,Overlaps}.Tao Bao2018-08-161-0/+26
| | | | | | Bug: 112151972 Test: Run recovery_unit_test on marlin. Change-Id: Ica2a7b3c768f5d8ca5d591a9560bca9f8ed847c5
* Add the hash_tree_info class in CommandTianjie Xu2018-08-141-0/+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
* Add an updater function to compute hash treeTianjie Xu2018-08-061-0/+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
* updater: Add ABORT command.Tao Bao2018-07-071-0/+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
* updater: Add Command parsing codes.Tao Bao2018-06-251-6/+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
* updater: Add Commmand class to manage BBOTA commands.Tao Bao2018-05-261-0/+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
* Add a singleton CacheLocation to replace the hard coded locationsTianjie Xu2018-02-281-1/+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
* Log the last command to cacheTianjie Xu2018-02-071-0/+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.

* Move Image/ImageChunk/PatchChunk declaration into header filesTianjie Xu2017-08-191-278/+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
* Add implemention of SortedRangeSetTianjie Xu2017-08-011-1/+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
* Change the internal representation in RangeSet.Tao Bao2017-04-031-28/+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
* Move parse_range() and range_overlaps() into RangeSet.Tao Bao2017-03-311-0/+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
* Replace minzip with libziparchiveTianjie Xu2016-10-181-2/+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
* Refactor libupdater into a seperate module.Tao Bao2016-10-113-0/+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
