-------------------------------------
Summary: Kill IMAP processing chain
Key: JAMES-3736
URL: https://issues.apache.org/jira/browse/JAMES-3736
Project: James Server
Issue Type: Improvement
Components: IMAPServer
Affects Versions: 3.7.0
Reporter: Benoit Tellier
Fix For: 3.8.0
Today we create a processor chain to manage IMAP request: each processor passes
the request to the next until the request is managed.
This leads to absurdly, needlessly long call stacks as we easily have 40+
processors.
- This have a performance impact as feeling thread stacks do not come for free
- Exceptions are hard to read (longer stacktraces)
- Reading flame graphs is also harder!
We should in my opinion just use a map to directly get the processor for a
given request, simply using the request class as a key.
