Throughout the years, the standard mechanism for storing passwords has evolved.
In the beginning, passwords were stored in plaintext. Developers are now
encouraged to leverage adaptive one-way functions to store a password. Using a
two-way function by default for storing passwords without a warning could lead
users to a false sense of security.
PriorityLinkedList has multiple sub-lists, before this commit PriorityLinkedList::setNodeStore would set the same node store between all the lists.
When a removeWithID was called for an item on list[0] the remove from list[4] would always succeed first. This operation would work correctly most of the time except
when tail and head is being used. Many NullPointerExceptions would be seen while iterating on the list for remove operations, and the navigation would be completely broken.
A test was added to PriorityLinkedListTest to make sure the correct lists were used however I was not able to reproduce the NPE condition in that test.
AccumulatedInPageSoakTest reproduced the exact condition for the NPE when significant load is used.
This commit uses lambdas or method references wherever possible. There
are still a handful of places that appear like they could be changed but
couldn't mainly because they use "this" and the meaning of "this"
changes when using a lambda.
This test is spinning a concurrent call on getDirectBindings
Since I added a synchronization point to get the Bindings the test could
be taking up to 5 seconds, being a variance between 500ms and 5 seconds.
Adding Thread.sleep(1) on this loop solved the issue as it is now letting other threads to do work
since I'm starting more executors than cores I have on my box.
Currently, with 500K+ queues, the cleanup step of TempQueueCleanerUpper
requires invoking WildcardAddressManager#getDirectBindings, which is
O(k) in the number of queues.
From method profiling, this can consume up to 95% of our CPU time when
needing to clean up many of these.
Add a new map to keep track of the direct bindings, and add a test
assertion that fails if we don't properly remove it.
This commit does the following:
- deprecate all QueueConfiguration ctors
- add `of` static factory methods for all the deprecated ctors
- replace any uses of the normal ctors with the `of` counterparts
This makes the code more concise and readable.

This is particularly true for the Mirrored SNF queue. Redistribution is not meant for internal queues. If an internal queue happens to have the same name on another server, it should not trigger redistribution when consumers are removed.
It would be possible to work around this by adding an address-setting specific to the address with redistribution disabled.
ClusteredMirrorSoakTest was intermittently failing because of this. For a few seconds while the mirror connection is still being made connections could move messages from one node towards another node if both have the same name.
- Move ActiveMQTestBase to artemis-test-support.
- Add reduced parent for current artemis-server tests.
- Add a simpler test case parent class unit tests can use.
- Convert some existing checks into a rule for reuse.
- Move various rules/utils to artemis[-unit]-test-support module from where they can be used instead of from artemis-server.
PagingStroeImpl.checkReleasedMemory() will kick off
executor.execute(this::memoryReleased) to pull from the queue onMemoryFreedRunnables
asynchronously. If the executor fires the task too late, it can pick up one of the
late trackMemoryChecks runnable and increase its calls, making assertion fail.
need to flush the executors to make sure it doesn't happen.
When initially developed the expectation was that no more producers would keep connecting but in a scenario like this
the consumers could actually give up and things will just accumulate on the server.
We should cleanup these upon disconnect.
- Async commit
* async here meaning the recording of the commit record is not doing a sync on the storage.
This is useful for internal operations where we don't need an immediate sync on the journal storage.
- Wired notification
* I need finer control on a afterWired (to the storage) and before the completions, so I can plug the sync context on mirror right before the commit is called.
This commit does the following:
- Replaces non-inclusive terms (e.g. master, slave, etc.) in the
source, docs, & configuration.
- Supports previous configuration elements, but logs when old elements
are used.
- Provides migration documentation.
- Updates XSD with new config elements and simplifies by combining some
overlapping complexTypes.
- Removes ambiguous "live" language that's used with regard to high
availability.
- Standardizes use of "primary," "backup," "active," & "passive" as
nomenclature to describe both configuration & runtime state for high
availability.
Allow for core messages to be tunneled over broker connection links used
for AMQP Federation and for broker mirroring. This eliminates the need to
convert from Core to AMQP and from loading core large messages fully into
memory for that conversion.
