Work Description: franz1981 commented on issue #2427: ARTEMIS-2170
Optimized CoreMessage's checkProperties and cleanupInternalProperties methods
URL: https://github.com/apache/activemq-artemis/pull/2427#issuecomment-456287327
> Just test core message in isolation franz. If an internal header is not
present it will not iterate through
I agree for adhoc unit tests, but common core exchanges include common
headers that are wrongly considered "internal" ie they start with `_AMQ_`,
making `internalProperties = true` and triggering cleaning up that won't clean
anything, given that the `internal properties` are indeed more specific.
I like your PR (but shocked by GitHUB THB), but I was concerned by the
amount of checks to be performed every time a new property is added and the
real cost to matain that flag consistent: the original version wasn't
considering cases where properties are removed/cleared etc etc: in that case
how much is consistent that flag?

> CoreMessage::checkProperties perform too many volatile read/write and has a
> too big body just to handle exceptional cases, while
> cleanupInternalProperties is called on the hot path of session send, but is
> performing too many synchronized operations and loopup on TypedProperties.
