Instead of wait to flush an executor,
I have added a method isFlushed() which will just translate to the
state on the OrderedExecutor.
In the case another executor is provided (for tests) there's a delegate
into normal executors.
delegate to the jdk saslServer. Allow acceptor configuration of supported mechanismis; saslMechanisms=<a,b>
and allow login config scope for krb5 to be configured via saslLoginConfigScope=x
This is replacing an executor on ServerSessionPacketHandler
by a this actor.
This is to avoid creating a new runnable per packet received.
Instead of creating new Runnable, this will use a single static runnable
and the packet will be send by a message, which will be treated by a listener.
Look at ServerSessionPacketHandler on this commit for more information on how it works.
Add krb5sslloginmodule that will populate userPrincipal that can be mapped to roles independently
Generalised callback handlers to take a connection and pull certs or peerprincipal based on
callback. This bubbled up into api change in securitystore and security manager
If replication blocked anything on the journal
the processing from clients would be blocked
and nothing would work.
As part of this fix I am using an executor on ServerSessionPacketHandler
which will also scale better as the reader from Netty would be feed immediately.
Core client with netty connector and acceptor doing kerberos
jaas.doAs around sslengine init such that the SSL handshake can do kerberos ticket
generaton and validation.
The kerberos authenticated user is then validated with the security manager before
being populated into the message userId.
The feature is enabled with the kerb5Config property. When lowercase it is the
principal. With a leading uppercase char it is the login.config entry to use.
The MAPPED journal refactoring include:
- simplified lifecycle and logic (eg fixed file size with single mmap memory region)
- supports for the TimedBuffer to coalesce msyncs (via Decorator pattern)
- TLAB pooling of direct ByteBuffer like the NIO journal
- remove of old benchmarks and benchmark dependencies
When a large message is replicated to backup, a pendingID is generated
when the large message is finished. This pendingID is generated by a
BatchingIDGenerator at backup.
It is possible that a pendingID generated at backup may be a duplicate
to an ID generated at live server.
This can cause a problem when a large message with a messageID that is
the same as another largemessage's pendingID is replicated and stored
in the backup's journal, and then a deleteRecord for the pendingID
is appended. If backup becomes live and loads the journal, it will
drop the large message add record because there is a deleteRecord of
the same ID (even though it is a pendingID of another message).
As a result the expecting client will never get this large message.
So in summary, the root cause is that the pendingIDs for large
messages are generated at backup while backup is not alive.
The solution to this is that instead of the backup generating
the pendingID, we make them all be generated in advance
at live server and let them replicated to backup whereever needed.
The ID generater at backup only works when backup becomes live
(when it is properly initialized from journal).
