Subject [jira] Commented: (DERBY-3184) Replication: Connection attempts to a database in slave mode must fail
Date Fri, 07 Dec 2007 13:42:43 GMT

Dyre Tjeldvoll commented on DERBY-3184:
---------------------------------------

The patch looks good, and all tests pass for me, +1. 

However, I'm not very familiar with the code being modified (the Monitor/Service system),
so I'll wait a little longer before I commit it, just to give others a chance to get their
comments in.

> When a database 'X' is booted in slave mode, the call to  Monitor.startPersistentService("X",...)
will not complete because the call gets stuck in LogToFile#recover. This is intentional.
> For as long as startPersistentService is blocked, however, other threads that try to
connect to 'X' (effectively calling Monitor.findService("X", ...)) will also hang. This is
unacceptable, and needs to raise an error.
