Add SQL functionality to DeleteProberDataAction (#1218 )

This includes a change to how the JPA transaction manager handles existence and load checks for entities with compound IDs. Previously, we relied on the fields all being named the same in the ID entity and the parent entity. This didn't work for History objects (e.g. DomainHistory) so existence checks were broken. Now, we use the methods the same way that Hibernate does (if possible). Note as well that there's a bit of semi-duplicated logic in DeleteProberDataAction (between the mapper and the SQL logic). The mapper code will be deleted once we've shifted to SQL, and for now it's better to keep it in place for logging purposes.
Implement read-only transaction manager modes for R3.0 migration (#1241 )

Author	SHA1	Message	Date
gbrodman	054c0625a8	Add SQL functionality to DeleteProberDataAction (#1218 ) This includes a change to how the JPA transaction manager handles existence and load checks for entities with compound IDs. Previously, we relied on the fields all being named the same in the ID entity and the parent entity. This didn't work for History objects (e.g. DomainHistory) so existence checks were broken. Now, we use the methods the same way that Hibernate does (if possible). Note as well that there's a bit of semi-duplicated logic in DeleteProberDataAction (between the mapper and the SQL logic). The mapper code will be deleted once we've shifted to SQL, and for now it's better to keep it in place for logging purposes.	2021-08-27 21:09:08 -04:00
gbrodman	b03639d7fc	Implement read-only transaction manager modes for R3.0 migration (#1241 ) This involves: - Altering both transaction managers to check for a read-only mode at the start of standard write actions (e.g. delete, put). - Altering both raw layers (entity manager, ofy) to throw exceptions on write actions as well - Implementing bypass routes for reading / setting / removing the schedule itself so that we don't get "stuck"	2021-08-27 15:59:16 -04:00

gbrodman	d57597f40f	Clean up ReplicateToDatastoreAction and tests (#1299 ) * Clean up ReplicateToDatastoreAction and tests 1. applyTransaction should throw an error if it fails; this allows us to have more information in the caller (and it shouldn't usually happen) 2. Set a response code + payload now, since this is an action that is called by cron 3. Add a method to the test log subject that allows us to check if a severe log with a particular Throwable cause was logged (since the cause isn't contained in the log message itself directly)	2021-08-25 14:45:05 -06:00
gbrodman	2641d0d462	Save indexes when replaying EppResources SQL->DS (#1300 ) * Save indexes when replaying EppResources SQL->DS We implement this similarly to how we implement the beforeSqlSaveOnReplay callback in the other direction -- a beforeDatastoreSaveOnReplay method that is called when replaying a Mutation to Datastore. This means that the asynchronous replay will create the relevant ForeignKeyIndex and EppResourceIndex objects for EppResources saved when SQL is primary.	2021-08-25 14:44:44 -06:00

Lai Jiang	1a26677d72	Implement a util class to manage push queues using Cloud Tasks API (#1290 ) * Implement a util class to manage push queues using Cloud Tasks API Push queues were part of App Engine when they debuted. As a result the Task Queue API were part of the App Engine SDK and can only be used in App Engine classic runtime. The new Cloud Tasks API can be used in any runtime but it only supports push queues. In this PR we implement a util class (CloudTasksUtils) like TaskQueueUtils to handle enqueuing tasks to push queues using Cloud Tasks. One action (TldFanoutAction) was converted to use the new API as a demo. Mass migration of other call sites of the old API will follow in a separate PR. TESTED=deployed to alpha and verified that tasks are corrected enqueued and executed.	2021-08-24 21:13:54 -04:00
gbrodman	f1beeb4016	Add double-replay to remaining existing ReplayExtension calls (#1297 ) The only other change is that we need to reconstitute serverApproveEntities for DomainTransferData in more situations (to fill out the ofy keys)	2021-08-23 15:08:09 -04:00
gbrodman	5c33286056	Compare SQL and Datastore objects in SQL->DS replay testing (#1291 ) Add double-replay to the Host*Flow tests to show how this works. The only change to the double replay itself is that now we store the Datastore entity in the TransactionEntity object -- this is because we use Objectify to serialize the objects into bytes and we need it to know about the entity in question.	2021-08-23 11:05:14 -04:00

Set the SqlReplayCheckpoint to a time before the smear backup that was used in step #1 (maybe 30 minutes) 4.

gbrodman	7a4c109b36	Remove recursive load in DBMSS cache (#1286 ) * Remove recursive load in DBMSS cache This occurs because if we do a standard transaction, the JpaTxnManager checks to see if we should be doing backups, which involves loading the migration state schedule (causing the recursion). When starting the transaction to load the schedule, we should explicitly transactWithoutBackup so there's no need to check. This wasn't hit in tests because we previously manually set the replication to not occur in the JpaTransactionManagerExtension -- we remove that and related setters.	2021-08-14 12:34:23 -06:00
