Subject [jira] Commented: (DERBY-3184) Replication: Connection attempts to a database in slave mode must fail
Date Fri, 11 Jan 2008 09:38:34 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3184?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12557948#action_12557948
] 

Øystein Grøvlen commented on DERBY-3184:
----------------------------------------

I discovered the func. spec. needs to be updated to reflect this patch.  Currently, the func
spec says:
"A valid connection to the database is returned to the caller of the startSlave command."
I guess this is no longer true with the latest patch.

> 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.
