In some setups, there could be a few hundred thousand queues that are
created due to many consumers that are connecting. However, most of
these are empty and stay empty for the entire day since there aren't
necessarily messages to be sent. The 8K intermediateMessageReferences
instantiates an 64KB buffer (Object[]). This means we have large
allocation and live heap that ultimately remains empty for almost the
entire day.
In this commit, we introduce initial-queue-buffer-size, which defaults
to the current value of 8192. It can be set programmatically via
QueueConfiguration#setInitialQueueBufferSize(int).
Note that this must be a positive power of 2.
The run command uses the artemis.profile and log4j2.properties files while all
other CLI commands use the artemis-utility.profile and log4j2-default.properties
files.
The test in this commit was distilled down from a much more complex
integration test that rarely reproduced the problem. It is short and
sweet and reproduces the problem every time.
The problem exists in the iterator's `remove()` method where it uses
`index` instead of `i` when calculating a new highest priority.
When using targeted FQQN permissions the AMQP sender needs to check that
it can access not only the address but also the queue if sent an FQQN so
that the security can validate if the sender has been granted directed
access to the FQQN as a whole.
Check that an attaching Openwire producer has SEND permission on the target
destination and reject it if it does not instead of delaying checks until the
actual send. For anonymous producers check early in the send process to reduce
overhead in the JVM handling messages that are going to fail to send.
One side of the mirror will send and ack messages one by one.
As the message arrives in the mirror the ack comes before the persistence finishes, so we need to retry and configure retry accordingly.
When counting messages with provided filters and grouping use the API
getObjectPropertyForFilter which translates values from AMQP message
annotations that are otherwise missed by the filters.
for regular messages it's quite obvious when the message is leaving the queue but for paged messages it becomes a challenge. We should just ignore the update for paged messages.
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).
