--------------------------------------------
Summary: DirectMessageWriter can write partial message header
Key: IGNITE-14824
URL: https://issues.apache.org/jira/browse/IGNITE-14824
Project: Ignite
Issue Type: Bug
Components: networking
Affects Versions: 3.0.0-alpha3
Reporter: Aleksandr Polovtcev
Assignee: Aleksandr Polovtcev
Fix For: 3.0.0-alpha3
{{DirectMessageWriter#writeHeader}} writes the message header as two {{short}}
values. This may result in problems, when the outgoing buffer only has less 2
or 3 bytes left, in which case only one {{short}} value will be actually sent.
Current code does not handle this situation properly, so it will send the whole
header again, despite that the first two bytes have already been transferred to
the receiving side.
