Both authentication and authorization will hit the underlying security
repository (e.g. files, LDAP, etc.). For example, creating a JMS
connection and a consumer will result in 2 hits with the *same*
authentication request. This can cause unwanted (and unnecessary)
resource utilization, especially in the case of networked configuration
like LDAP.
There is already a rudimentary cache for authorization, but it is
cleared *totally* every 10 seconds by default (controlled via the
security-invalidation-interval setting), and it must be populated
initially which still results in duplicate auth requests.
This commit optimizes authentication and authorization via the following
changes:
- Replace our home-grown cache with Google Guava's cache. This provides
simple caching with both time-based and size-based LRU eviction. See more
at https://github.com/google/guava/wiki/CachesExplained. I also thought
about using Caffeine, but we already have a dependency on Guava and the
cache implementions look to be negligibly different for this use-case.
- Add caching for authentication. Both successful and unsuccessful
authentication attempts will be cached to spare the underlying security
repository as much as possible. Authenticated Subjects will be cached
and re-used whenever possible.
- Authorization will used Subjects cached during authentication. If the
required Subject is not in the cache it will be fetched from the
underlying security repo.
- Caching can be disabled by setting the security-invalidation-interval
to 0.
- Cache sizes are configurable.
- Management operations exist to inspect cache sizes at runtime.
This is allowing journal appends to happen in burst
during replication, by batching replication response
into the network at the end of the append burst.
I couldn't reproduce this with a test, but static code analysis led me
to this solution which is similar to the fix done for ARTEMIS-2592 via
e397a17796.
1 of 2) - Porting of HORNETMQ-1575
In a live-backup scenario, when live is down and backup becomes live, clients
using HA Connection Factories can failover automatically. However if a
client decides to create a new connection by itself (as in camel jms case)
there is a chance that the new connection is pointing to the dead live
and the connection won't be successful. The reason is that if the old
connection is gone the backup will not get a chance to announce itself
back to client so it fails on initial connection.
The fix is to let CF remember the old topology and use it on any
initial connection attempts.
Since getDiskStoreUsage on the ActiveMQServerControl is converting a
double to a long the value is always 0 in the management API. It should
return a double instead.
Adding this metric required moving the meter registration code from the
AddressInfo class to the ManagementService in order to get clean access
to both the AddressInfo and AddressControl classes.
The calculation used by
ActiveMQServerControlImpl.getDiskStoreUsagePercentage() is incorrect. It
uses disk space info with global-max-size which is for address memory.
Also, the existing getDiskStoreUsage() method *already* returns a
percentage of total disk store usage so this method seems redundant.
Now it is possible to reset queue parameters to their defaults by removing them
from broker.xml and redeploying the configuration.
Originally this PR covered the "filter" parameter only.
ORIG message propertes like _AMQ_ORIG_ADDRESS are added to messages
during various broker operations (e.g. diverting a message, expiring a
message, etc.). However, if multiple operations try to set these
properties on the same message (e.g. administratively moving a message
which eventually gets sent to a dead-letter address) then important
details can be lost. This is particularly problematic when using
auto-created dead-letter or expiry resources which use filters based on
_AMQ_ORIG_ADDRESS and can lead to message loss.
This commit simply over-writes the existing ORIG properties rather than
preserving them so that the most recent information is available.
- when sending messages to DLQ or Expiry we now use x-opt legal names
- we now support filtering thorugh annotations if using m. as a prefix.
- enabling hyphenated_props: to allow m. as a prefix
DivertBindings are now properly cleaned up when a queue binding is
removed that matches the divert. The correct key is now used to remove
the queue address from the set and the correct address is now used to
remove the remote consumer.
Test fails with the primary server being killed by the crash and the backup server is killed
by the tearDown before ScaleDownHandler can kick in. This commit adds a wait method to allow
ScaleDownHandler to process before the test completes.
AmqpExpiredMessageTest will expire messages, eventually the counter could be 0
so it is invalid to assertEquals(1, queue.getMessageCount()) as it will be 0 eventually.
This one should improve eventual failures on ClusterConnectionControlTest
to validate this, run ClusterConnectionControlTest::testNotifications in a loop
you will see eventually the test taking longer to shutdown the executor as the call could be blocked.
This won't be an issue on a real server (Production system)
however, on the testsuite or while embedded this could cause issues,
if a same instance is stopped then started.
This is the reason why BackupAuthenticationTest was intermittently failing.
I also adapted the test since I would need to stop the server and reactivate it in order to change the configuration.
The previous test wasn't acting like a real server.
This commit does the following:
- Deprecates existing overloaded createQueue, createSharedQueue,
createTemporaryQueue, & updateQueue methods for ClientSession,
ServerSession, ActiveMQServer, & ActiveMQServerControl where
applicable.
- Deprecates QueueAttributes, QueueConfig, & CoreQueueConfiguration.
- Deprecates existing overloaded constructors for QueueImpl.
- Implements QueueConfiguration with JavaDoc to be the single,
centralized configuration object for both client-side and broker-side
queue creation including methods to convert to & from JSON for use in
the management API.
- Implements new createQueue, createSharedQueue & updateQueue methods
with JavaDoc for ClientSession, ServerSession, ActiveMQServer, &
ActiveMQServerControl as well as a new constructor for QueueImpl all
using the new QueueConfiguration object.
- Changes all internal broker code to use the new methods.
Due to the changes in 6b5fff40cb the
config parameter message-expiry-thread-priority is no longer needed. The
code now uses a ScheduledExecutorService and a thread pool rather than
dedicating a thread 100% to the expiry scanner. The pool's size can be
controlled via scheduled-thread-pool-max-size.
Using a property on AMQPLargeMessage instead of a ThreadLocal
This was causing issues on the journal as the message may transverse different threads on the journal.
There is no guarantee that the encodeSize size is the same in AMQP right after read.
As the protocol may add additional bytes right after decoded such as header, extra properties.. etc.
The drain control has to immediately flush
otherwise a next flow control event may remove the previous status from Proton.
So, this really cannot wait the next executor, and it has to be done immediately.
Historically speaking, all message properties starting with AMQ HDR
would not be passed to OpenWire messages. However, that blocked the
properties from management notifications so ARTEMIS-1209 was raised and
the solution there was to pass properties that started with _AMQ *if*
the consumer was connected to the management notification address.
However, in this case messages are diverted to a different address so
this check fails and the properties are removed. My solution will be to
check the message itself to see if it has the _AMQ_NotifType property
(which all notification messages do) rather than checking where the
consumer is connected.
In case there is a hardware, firewal or any other thing making the UDP connection to go deaf
we will now reopen the connection in an attempt to go over possible issues.
This is also improving locking around DiscoveryGroup initial connection.
This is a Large commit where I am refactoring largeMessage Body out of CoreMessage
which is now reused with AMQP.
I had also to fix Reference Counting to fix how Large Messages are Acked
And I also had to make sure Large Messages are transversing correctly when in cluster.
