9 daysdisable op count overhead for v2HEADmastermainDaniel Zheng
v2 does not use op buffer count, so this estimation overhead should only be updated for v3 Test: th Change-Id: Ib9ad838abd03839db390b0dbd126c1a477803eea
2024-04-12update_engine: never enable BCJ.Elliott Hughes
This was only enabled for 32-bit, has been demonstrated not to reduce OTA sizes, and we have a build in dogfood that can't decode BCJ output. Bug: http://b/333826436 Change-Id: I3cd81b65f943d4ab6c5d981dbe6e9d5bf336e612
2024-04-10prefs: return success if nothing to deleteDaniel Zheng
In the case that transaction submission is interrupted in between a delete an rename, upon next reboot, the prefs directory will not exist. Update_engine will attempt to swap prefs (e.g. rename prefs_tmp to prefs), but will fail here since prefs has already been deleted. We should return true if there is nothing to delete, and continue the rename Test: th Change-Id: I08725eb412f043187990c984caab049648c151ad
2024-04-08cow estimator: terminate on bad writeDaniel Zheng
If a write failure occurs, we should log an error and then terminate estimation. Otherwise we might have a false positive, and have a faulty OTA package generated Bug: 332640740 Test: th Change-Id: Ib72a7b66b7f0c25b89be64172ce68d1de077077e

2024-03-26v3 cow estimatorDaniel Zheng
Use extent writer as abstraction layer for both estimation and ota installation. Going over install operations will match the logic used in delta_performer to accurattely size the cow. Extent_writer abstraction takes care of chunking the data for us. To account for FEC data and hash tree writes, we want to add a little bit of overhead as AddRawBlocks calls are per verity hash tree level. In the case of small partitions, we want to set the overhead to a hard number rather than a percentile To ensure that our estimator is backwards compatible for downgrade OTA's, we should add labels after each operation is processed (although this isn't needed for sizing a v3 cow).

2024-03-18Add a version of update engine that does not send statsNikita Putikhin
update_engine_nostats has the same functionality as the update_engine but without interaction with statsd libraires and without build dependency on it. Test: Apply an upadte to an aosp cf vm - note that merge stats are reported in logcat. Replace update engine with the nostats service in the product packages and apply an update - note that stats reporting is skipped. Bug: 328227527 Change-Id: Iba87119838ecb9bdd8c94f8a913ec0d6e86a26d1
