This commit fixes 3 distinct issues with bridge configuration encoding:
- The encoding size was calculated incorrectly in three ways:
- Using 0 instead of `DataConstants.SIZE_NULL` when no transformer is
defined resulting in a calculated size discrepancy of -1.
- Using `DataConstants.INT` instead of `DataConstants.SIZE_INT` for
the number of transformer properties resulting in a calculated size
discrepancy of +2 when using a configuration with a transformer.
- Using 0 or `sizeOfNullableInteger` instead of
`DataConstants.SIZE_INT` for the number of static connectors
resulting in a variable calculated size discrepancy of either -4 or
+1 respectively.
- Encoding was using `writeString` instead of `writeNullableString` for
the name of the transformer class resulting in an actual buffer size
discrepancy of -1.
Aside from these fixes this commit also adds new tests specifically for
encoding & decoding include a test to verify known bytes during
encoding.
Lastly, it's worth noting that this *won't fix* bad data that was
already stored to disk by an older broker or bad data that comes over
the wire from an older broker (e.g. if a older primary broker paired
with a newer backup).
During the investigation for ARTEMIS-4910 it was noted that some of the
storage manager tests didn't actually force a full reload (i.e.
decoding) of the various configurations from disk. This commit does the
following:
- refactors these tests so that they all force a reload from disk
- organizes imports
- eliminates various bits of repeated code in all the tests
- improves code formatting
This commit exposes a bug in the encoding/decoding of
BridgeConfiguration via a failing test in
BridgeConfigurationStorageTest. This test is disabled. This failure will
be resolved in a subsequent commit at which point the test will be
enabled again.
The `ManagementService` is used by the broker to register and
unregister components for management as well as send notifications.
When the broker is busy dealing with new sessions and auto-creating
queues, addresses, etc. there is a lot of contention.
To reduce synchronization and improve the service overall this commit
does the following:
- Remove `synchronized` from most methods. In most cases it's
completely unnecessary because the methods are already using a
thread-safe data-structure (e.g. `ConcurrentHashMap`) or more
specific synchronization is already in place (e.g. on
`mbeanServer`).
- Adds new & clarifies existing logging.
- Synchronizes `start` & `stop` methods and adds gates via `started`.
- Simplifies the `sendNotification` method by synchronizing once rather
than twice and performing legitimacy checks sooner.
- Removing an unnecessary overload of the `registereQueue` method.
To be clear, there are no tests included with this commit as there
should be no semantic changes. Existing tests should be sufficient to
identify any regressions.
If, for whatever reason, the response for a packet sent with blocking
semantics is never returned it's possible that an async response
received in the interventing time will be interpreted as the current
response. This is because ChannelImpl does not verify the correlation
ID set on the response packet when it is received.
Small change but say there's ever a leak on the journal. Removing the clause from paging would allow to also capture other leaks.
This is currently not an issue and the test should still pass.
No need for the iterations, and a few minor improvements to the test.
This method was taking up to 15 seconds on the CI and the same method is reused a couple times, resulting in many minutes wasted
This commit fixes 4 distinct issues with divert configuration encoding:
- The encoding size was calculated incorrectly in three ways:
- Using 0 instead of `DataConstants.SIZE_NULL` when no transformer is
defined resulting in a calculated size discrepancy of -1.
- Using `DataConstants.INT` instead of `DataConstants.SIZE_INT` for
the number of transformer properties resulting in a calculated size
discrepancy of +2 when using a configuration with a transformer.
- Using `BufferHelper.sizeOfNullableBoolean` instead of
`DataConstants.SIZE_BOOLEAN` for the `exclusive` property resulting
in a calculated discrepancy of +1.
- Encoding was using `writeString` instead of `writeNullableString` for
the name of the transformer class resulting in an actual buffer size
discrepancy of -1.
Aside from these fixes this commit also:
- Updates the divert storage test to force a reload from disk which
will also trigger this problem.
- Adds new tests specifically for encoding & decoding include a test to
verify known bytes during encoding.
Lastly, it's worth noting that this *won't fix* bad data that was
already stored to disk by an older broker or bad data that comes over
the wire from an older broker (e.g. if a older primary broker paired
with a newer backup).
Files will leak on the target and messages will not be received after failover.
Also messages will be written to wrong destinations on the replica. The leak is actually between destinations, and the consequence is the file leak.
I usually keep test and fix on the same commit, but in this case I have been heavily validating the server with and without the fix,
so I will open an exception in this case and keep the fix and test separated.
