- Disable tablets in `test_migration_on_existing_raft_topology`.
Because views on tablets are experimental now, we can safely
assume that view building coordinator will start with view build status
on raft.
- Add error injection to pause view building on worker.
Used to pause view building process, there is analogous error injection
in view_builder.
- Do a read barrier in `test_view_in_system_tables`
Increases test stability by making sure that the node sees up-to-date
group0 state and `system.built_views` is synced.
- Wait for view is build in some tests
Increases tests stability by making sure that the view is built.
- Remove xfail marker from `test_tablet_streaming_with_unbuilt_view`
This series fix https://github.com/scylladb/scylladb/issues/21564
and this test should work now.
In the present scenario, the bootstrapping node undergoes synchronize phase after
initialization of group0, then enters post_raft phase and becomes fully ready for
group0 operations. The topology coordinator is agnostic of this and issues stream
ranges command as soon as the node successfully completes `join_group0`. Although for
a node booting into an already upgraded cluster, the time duration for which, node
remains in synchronize phase is negligible but this race condition causes trouble in a
small percentage of cases, since the stream ranges operation fails and node fails to bootstrap.
This commit addresses this issue and updates the error throw logic to account for this
edge case and lets the node wait (with timeouts) for synchronize phase to get over instead of throwing
error.
A regression test is also added to confirm the working of this code change. The test adds a
wait in synchronize phase for newly joining node and releases only after the program counter
reaches the synchronize case in the `start_operation` function. Hence it indicates that in the
updated code, the start_operation will wait for the node to get done with the
synchronize phase instead of throwing error.
This PR fixes a bug. Hence we need to backport it.
Fixes: scylladb/scylladb#23536Closesscylladb/scylladb#23829
The new option deprecates the existing `enable_tablets` option.
It will be extended in the next patch with a 3rd value: "enforced"
while will enable tablets by default for new keyspace but
without the posibility to opt out using the `tablets = {'enabled':
false}` keyspace schema option.
