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.
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"
* 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)
* 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.
* 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.
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.
* Remove ReservedList from Datastore schema
* Remove some Datastore references
* Add a different non-replicated entity to ReplayCommitLogsToSqlActionTest
* 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.
* Generate string to uniquely identify a SqlEntity
Add a method to SqlEntity that returns a string built from the entity's
primary key(s). This string can be used in logging.
* Store DatabaseMigrationSchedule in SQL instead of Datastore
This requires messing around with some of the JPA unit test rule
creation since it requires saving / retrieving the schedule pretty much
always (which itself includes the hstore extension).
* Remove PremiumList from Datastore schema
* Remove commented out code
* Change lastUpdateTime to creationTimestamp
* Remove extra file
* Remove currency unit from input data to parse
* Revert extra file
* Check currency in parse
* Create all PremiumEntries before saving them in bulk
* small fixes
* Fix merge conflict
There was a subtle issue that we encountered in sandbox when using one
transaction per file that was difficult to replicate. Basically,
1. Save a domain with dsData
2. Save the domain without dsData
3. Save the domain with the same dsData as step 1
4. Delete literally any object
If one performs steps 2-4 in the same transaction, Hibernate will throw
an exception (cascade re-saving a cascade-deleted object). Note that
step 4 is in fact necessary to reproduce the issue, yay Hibernate.
We will test this and if one transaction per transaction is too slow,
we'll figure out ways to reduce the number of SQL transactions.
This PR re-implements most of the logic in the RdeStagingReducer, with
the exception of the last enqueue operations, due to the fact that the
task queue API is not available outside of App Engine SDK. This part
will come in a separate PR.
Another deviation from the reducer is that we forwent the lock -- it is
difficult do it across different beam transforms. Instead we write each
report to a different folder according to its unique beam job name. When
enqueueing the publish tasks we will then pass the folder prefix as a
URL parameter.

This is instead of the current configuration parameter.
In addition, this adds some helpers to DatabaseHelper to make the
transitions easier, since we more frequently need to alter + reset the
schedule.
If we use the transaction manager methods, JpaTransactionManagerImpl
will attempt to detach the EppResource in question that we're loading --
this fails because that entity has been saved in the same transaction
already. We don't need detaching during these methods (it's just for
resource population) so we can use the raw loads to get around it.
* Remove KmsSecret model entities
Now that we have been using the SecretManager for almost a month now,
remove the KmsSecret and KmsSecretRevision entities from Java code base.
A follow-up PR will drop the relevant tables in the schema.
Also removed a few unused classes in the beam package.
* Fix runtime issues with commit-log-to-SQL replay
- We now use a more intelligent prefix to narrow the listObjects search
space in GCS. Otherwise, we're returning >30k objects which can take
roughly 50 seconds. This results in a listObjects time of 1-3 seconds.
- We now search hour by hour to efficiently make use of the prefixing.
Basically, we keep searching for new files until we hit the current time
or until we hit the overall replay timeout.
- Dry-run only prints out the first hour's worth of files
* Fix hanging threads in GcsDiffFileLister
Basically, whenever we request threads using the request thread factory,
we must be on the request thread itself. Dagger doesn't guarantee this
for us if we provide the ExecutorService directly in the action (or in
the GcsDiffFileLister), but we can gurantee that we're on the request
thread itself by simply injecting a Lazy, so that the executor is
instantiated inside the request itself.
In addition, add a timeout on the futures just in case.
* Use the DatabaseMigrationSchedule to determine which TM to use
We still allow the "manual" specification of a particular transaction
manager, most useful in @DualDatabaseTest classes. If that isn't
specified, we examine the migration schedule to see which to return.
Notes:
- This requires that any test that sets the migration schedule clean up
after itself so that it won't affect future test runs of other classes
(because the migration schedule cache is static)
- One alternative would, instead of having a "test override" for the
transaction manager, be to examine the registry environment and only
override the transaction manager in the UNIT_TEST environment. This
doesn't work because there are many instances in which tests simulate
non-test environment.
The API provided by the GAE SDK will not be available outside GAE
runtime. This presents a problem when we migrate off of GAE. More
pressingly, the RDE pipeline migration to Beam requires that we write to
GCS on GCE. Previously we were able to sidestep the issue by delegating
the writes to FileIO provided by Beam, which knows how to write to GCS.
However the RDE pipeline cannot use FileIO directly as it needs to write
to multiple files in one go and explicit use of GCS API is needed.
An unfortunate side effect of the API migration is that the new testing
library contains a bug which makes serializing GcsUtils impossible. It
is fixed upstream but not released yet. The fix has been backported for
the time being.

* Restore commit logs from other project
Allow non-production projects to restore commit logs from another
project. This feature can be used to duplicate a realistic testing
environment.
An optional parameter is added that can override the default commit log
location.
Tested successfully in QA.
* Remove old DomainList fields from Registry
I also resaved all Registry objects in sandbox and production to make sure that the new field is populated on all entity objects.
* small fixes
* Some more small fixes
* Delete commented out code
* Remove existence check in tests
* Set payload response in happy path of ReplayCommitLogsToSqlAction
I suspect this may be the reason the logs are missing on the happy path (when it
runs successfully), but are visible on the exception paths (which do set the
payload response). I don't think App Engine likes it when a Web request
terminates without a response.
This also adds more logging and error handling.
This is the first part of the RdeStagingAction SQL migration where the
mapper logic is implemented in Beam.
A few helper methods are added to convert the DomainContent, HostBase
and ContactBase to their respective terminal child classes. This is
necessary and possible because the child classes do not have extra
fields and the base classes exist only to be embedded to other entities
(such as the various HistoryEntry entities). The conversion is necessary
because most of our code expects the terminal classes, such as the
RdeMarshaller's various marshallXXX() methods. The alternative would be
to change all the call sites, which seems to be much more disruptive.
Unfortunately there is is no good way to do this conversion than just
creating a builder and setting every fields there is.
