Allow setting id-cache-size to 0 from broker.xml and ensure the broker
handles this gracefully. Previously you could only set the cache size to
0 via broker properties or programmatically and it would throw an
ArrayIndexOutOfBoundsException when adding an item to the cache.
- From now on we will save snapshots of page-counters on the journal (basically for compatibility with previous verions).
And we will recount the records on startup.
- While the rebuild is being done the value from the previous snapshot is still available with current updates.
when cancelling a large number of messages, the addSorted could be holding a lock for too long causing the server to crash under CriticalAnalyzer

- otpimize getNextPage() on complete pages
- optimize getFirstMessage() and paging. (avoid iterator usage)
Attempt to standardize all Logger declaration to a singular variable name
which makes the code more consistent and make finding usages of loggers in
the code a bit easier.
Commit 5a42de5fa6 called my attention to
this test. It really needs to be refactored because:
- It belongs in the integration-tests module rather than the MQTT
protocol module.
- It is using a lot of non-standard components (e.g.
EmbeddedJMSResource, Awaitility, etc.).
- It is overly complicated (e.g. using its own MqttClientService).
This commit resolves all those problems. The new implementation is quite
a bit different but still equivalent. I reverted the original fix from
ARTEMIS-2476 and the test still fails.
Logger statements should use formatting syntax and let the normal framework checks take care of
checking if a logger is enabled instead of string concats and isXEnabled logger checks except
in cases there is known expense to the specifc logging message/arg preparation or passing.
Changes from myself and Robbie Gemmell.

The issue is that depage should not put pages on the used pages as they were not actually intended to read.
instead I should create a newPageObject and not use the RefCounts caching.
I did not intend to have this difference in the semaphore.
The idea is that we never keep messages pending on this case, otherwise such a huge message would use too much memory.
I was debugging Compacting, looking for a possible issue here in these conditions.
even though I found nothing wrong with the code, I still want to keep the test as there's no such thing as enough testing.
In commit a9a85f98db I removed the code
which modified existing matches. However, I forgot that the matches read
from LDAP are often duplicated so instead of always adding a new match
this commit ensures that the *right* match is modified rather than a
potentially more generic wildcard match (which was the original
problem).
If an AMQP consumer tries to receive a message and the broker is unable
to convert the message from core to AMQP then the consumer is
disconnected and the offending message stays in the queue. When the
consumer reconnects the conversion error will happen again resulting in
a loop that can only be resolved through administrative action (e.g.
deleting the message manually or sending it to a dead letter address).
This commit fixes that problem by detecting the conversion problem and
sending the message to the queue's dead letter address. It also doesn't
disconnect the consumer.
This commit also changes the log messages associated with sending a
message to the dead letter address since this event can now occur
regardless of the delivery attempts.
The map used by LastValueQueue was inadvertently changed to a
non-thread-safe implementation in
4a4765c39c. This resulted in an occasional
ConcurrentModificationException from the hashCode implementation.
This commit restores the thread-safe map implementation and adds a test
which brute-forces a CME when using the non-thread-safe implementation.
Sometimes users want to perform custom client ID validation, and in the
case of an invalid client ID the proper reason code should be returned
in the CONNACK packet.
When the LegacyLDAPSecuritySettingPlugin has enableListener set to true
and a new permission is added it will try to modify the existing match
if one exists. This is problematic if there's a more generic wildcard
match than the specific one that's modified.
This commit fixes that problem so that instead of modifying the existing
match(es) it simply adds a new one. The plugin never should have tried
modifying the existing match in the first place as two identical matches
would be a configuration error.
- Fixing RoleInfo to provide informations on deleteAddress.
- Adding more coverage on test to check the number of permissions
returned.

By allowing to pass caller's classname directly to org.apache.activemq.artemis.utils.ActiveMQThreadFactory#defaultThreadFactory instead of calculating it from stack.
Due to the changes in 682f505e32 we now
send "Last Will & Testament" MQTT messages via ServerSession. This means
sending will fail if the disk is full. For MQTT this triggers a
connection failure which in turns triggers sending an LWT message. This
process will recurse infinitely until it results in a
java.lang.StackOverflowError.
This commit fixes that by tracking whether or not sending a LWT message
is already in progress.
When a message is sent to an anycast queue via FQQN on one node of a
cluster and then a consumer is created on that same anycast queue via
FQQN on another node in the cluster the message is not redistributed to
the node with the consumer.
This commit fixes this use-case primarily by including the FQQN info in
the notification messages sent to other nodes in the cluster.
These scripts are supposed to be execute with ". ./parameters-paging.sh"
which would incur in -e, and any mistake on the shell will kill your shell and you would be wondering what happened.
Using direct routing skips authorization for "Last Will and Testament"
messages (a.k.a. "will" messages). This commit fixes that problem by
using the internal session that is established for normal message
production and consumption.
Messages without a last-value property sent to an LVQ are being pruned
rather than just passing through. Only messages with a non-null
last-value property should be subject to pruning.
Running HorizontalPagingTest with these variables would make the test to fail unless these changes are applied.

The OpenWire JMS client shipped with ActiveMQ "Classic" uses the
client's hostname as part of the `JMSMessageID`. Consumers may use this
data to select messages sent from particular hosts. Although this is
brittle and not recommended it is nonetheless possible.
However, when messages arrive to ActiveMQ Artemis they are converted
to core messages, and the broker doesn't properly map the selector from
`JMSMessageID` to the corresponding property on the underlying core
message. This commit fixes that problem. Changes include:
- Mapping selector from JMSMessageID to the internal __HDR_MESSAGE_ID
- Relocating some constant values so that both the protocol and commons
module can use them
- Adding a test
AddressControl has 2 methods to get same metric. Both
getNumberOfMessages() and getMessageCount() return the same metric
albeit in different ways.
Also, getNumberOfMessages() inspects both "local" and "remote" queue
bindings which is wrong.
This commit fixes these issues via the following changes:
- Deprecate getNumberOfMessages().
- Change getNumberOfMessages() to invoke getMessageCount().
- Add a test to ensure getNumberOfMessages() does not count remote
queue bindings.
- Simplify getMessageCount(DurabilityType).
The condition fixed on this commit should not really happen in production
as the compacting counts should always be ordered (records that were compacted earelier will always be at the top of the journal).
However it highlights an improvement that could be done on the journal compacting.
MQTT 3.1 and 3.1.1 clients using a clean session should have a
*non-durable* subscription queue. If the broker restarts the queue
should be removed. This is due to [MQTT-3.1.2-6] which states that the
session (and any state) must last only as long as the network
connection.
This is caused by too many entries on the HashMap for ThreadLocals.
Also: I'm reviewing some readlock usage on the StorageManager to simplify things a little bit.
JMSTestCase is deprecated anyway.
in its older form many many years ago a server would be reused over
between tests.
what forced us to make such verification to avoid messages from one test
leaking into the next.
This was because a server startup was expensive many years ago (less
efficient code and the hardware available 10 years ago)
with the current state of things this is not needed as the server will
be started from scratch on every test
