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.
When a bridge is stopped it doesn't wait for pending send
acknowledgements to arrive. However, when a bridge is paused it does
wait. The behavior should be consistent and more importantly
configurable. This commit implements these improvements and generally
refactors BridgeImpl to clarify and simplify the code. In total, this
commit includes the follow changes:
- Removes the hard-coded 60-second timeout for pending acks when
pausing the bridge and adds a new config parameter (i.e.
"pending-ack-timeout").
- Applies the new pending-ack-timeout when the bridge is stopped.
- Updates existing and adds new logging messages for clarity.
- De-duplicates code for sending bridge-related notifications.
- Avoids converting bridge name to/from SimpleString.
- Removes unnecessary comments.
- Renames variables & functions for clarity.
- Replaces the `started`, `stopping`, & `active` booleans with a
single `state` variable which is an enum.
- Adds `final` to a few variables that were functionally final.
- Synchronizes `stop` & `pause` methods to add safety when invoked
concurrently with `handle` (since both deal with `state` and execute
runnables on the ordered executor).
- Reorganizes and removes a few methods for clarity.
- Relocates `connect` method directly into `ConnectRunnable` (mirroring
the structure of the `StopRunnable` and `PauseRunnable`).
- Eliminates unnecessary variables in `ConnectRunnable` and
`ScheduledConnectRunnable`.
- Adds test to verify pending ack timeout works as expected with both
`stop` & `pause` with both regular and large messages.
Handle any exceptions from the proton transport and set the error on the
transport for processing in the events dispatch cycle by adding in handling
of the transport error event.
- switch to using maven-core instead of ancient maven-project dep
- set provided scope on various deps that should have it, fix warnings
- use transitive maven-resolver-api from -core, its also 'provided'
- add a property to update common component versions
