If replication blocked anything on the journal
the processing from clients would be blocked
and nothing would work.
As part of this fix I am using an executor on ServerSessionPacketHandler
which will also scale better as the reader from Netty would be feed immediately.
Core client with netty connector and acceptor doing kerberos
jaas.doAs around sslengine init such that the SSL handshake can do kerberos ticket
generaton and validation.
The kerberos authenticated user is then validated with the security manager before
being populated into the message userId.
The feature is enabled with the kerb5Config property. When lowercase it is the
principal. With a leading uppercase char it is the login.config entry to use.
The MAPPED journal refactoring include:
- simplified lifecycle and logic (eg fixed file size with single mmap memory region)
- supports for the TimedBuffer to coalesce msyncs (via Decorator pattern)
- TLAB pooling of direct ByteBuffer like the NIO journal
- remove of old benchmarks and benchmark dependencies
When a large message is replicated to backup, a pendingID is generated
when the large message is finished. This pendingID is generated by a
BatchingIDGenerator at backup.
It is possible that a pendingID generated at backup may be a duplicate
to an ID generated at live server.
This can cause a problem when a large message with a messageID that is
the same as another largemessage's pendingID is replicated and stored
in the backup's journal, and then a deleteRecord for the pendingID
is appended. If backup becomes live and loads the journal, it will
drop the large message add record because there is a deleteRecord of
the same ID (even though it is a pendingID of another message).
As a result the expecting client will never get this large message.
So in summary, the root cause is that the pendingIDs for large
messages are generated at backup while backup is not alive.
The solution to this is that instead of the backup generating
the pendingID, we make them all be generated in advance
at live server and let them replicated to backup whereever needed.
The ID generater at backup only works when backup becomes live
(when it is properly initialized from journal).
This method name would clash with ServiceComponent
As the real meaning here on this method is just to failover
So I've renamed the method to avoid the clash with my next commit
(I've done this on a separate commit as you may need to redo this
commit from scratch again in other branches instead of lots of clashes on cherry-pick)
When a large message is being diverted, a new copy of the original
message is created and replicated (if there is a backup) to the backup.
In LargeServerMessageImpl.copy(long) it reuse a byte array to copy
message body. It is possible that one block of date is read into
the byte array before the previous read has been replicated,
causing the replicated bytes to corrupt.
If we make a copy of the byte array before replication, the corruption
of data will be avoided.
Before sending of messages to server 0 begins, the test
should wait until consumer is registered at RemoteQueueBindingImpl
on server 0. Otherwise some messages may not be rebalanced
to server 1.
it doesn't really matter the number of files.. as long as the data is valid.
This type of assertion limits the implementation. it's mocking test with too much intrusion
over the implementation. Hence I'm removing these clauses that will fail eventually.
Add extra configuration to address-settings to be able to
control / enable address/queue deletion by pattern,
rather than a global toggle.
Add support in the reload logic to remove address
and/or queues if the address matches an address setting,
where it is enabled.
When a broken packet arrives at client side it causes decoding error.
Currently artemis doesn't handle it properly. It should catch such
errors and disconnect the underlying connection, logging a proper
warning message
Use AcitveMQDestination for subscription naming, fixing and aligning queue naming in the process.
The change is behind a configuration toggle so to avoid causing any breaking changes for uses not expecting.
In a cluster if a node is shut down (or crashed) when a
message is being routed to a remote binding, a internal
property may be added to the message and persisted. The
name of the property is like _AMQ_ROUTE_TOsf.my-cluster*.
if the node starts back, it will load and reroute this message
and if it goes to a local consumer, this property won't
get removed and goes to the client.
The fix is to remove this internal property before it
is sent to any client.
Update ActiveMQConnection to change/alighn behaviour for addtional methods:
- getMetaData
- stop
Adding test to avoid regression.
This is aligning with qpid-jms and openwire clients
Adds headers AMQ_SCHEDULED_DELAY and AMQ_SCHEDULED_TIME to STOMP
protocol handling to allow for delayed and scheduled time of a
message. The AMQ_SCHEDULED_DELAY brings forward the same option
from the 5.x broker and the AMQ_SCHEDULED_TIME option adds a fixed
time of delivery alternative to match that of AMQP and others.
Add test case, to prove the issue, and then obviously ensure it works, post fix.
Apply changes in logic of createQueueName to handle global better and fix the behaviour.
Create queues so names are same as behaviour with core client.
Add topic and queue cache maps in Session.
Add configuration to use cache or not with defaulting to false, which keeps existing behaviour as the default.
