Anand Mazumdar updated MESOS-4255:
----------------------------------
Description:
Currently, the slave process generates a process ID every time it is
initialized via {{process::ID::generate}} function call. This is a problem for
testing HTTP executors as it can't retry if there is a disconnection after an
agent restart since the prefix is incremented.
{code}
Agent PID before:
slave(1)@127.0.0.1:43915
Agent PID after restart:
slave(2)@127.0.0.1:43915
{code}
There are a couple of ways to fix this:
- Add a constructor to {{Slave}} exclusively for testing that passes on a fixed
{{ID}} instead of relying on {{ID::generate}}.
- Currently we delegate to slave(1)@ i.e. (1) when nothing is specified as the
URL in libprocess i.e. {{127.0.0.1:43915/api/v1/executor}} would delegate to
{{slave(1)@127.0.0.1:43915/api/v1/executor}}. Instead of defaulting to (1), we
can default to the last known active ID.
