Kristian Waagan updated DERBY-4700:
-----------------------------------
Attachment: derby-4700-2a-static_bogus.diff
Patch 2a makes the bogus port static, such that it is shared between all
TestConfiguration instances in a VM. It also increases the max port count to 11
- we're already using that many ports so the next change that requires another
alternative port will trigger the assert in getNextAvailablePort().
Regression tests passed (traditional serial run).
Patch ready for review.
I do plan to commit this fix shortly to stop the tinderbox test from failing.
I'll update the wiki page when I commit.
> Add method to obtain a bogus port in TestConfiguration

> In some cases one needs to obtain a port number on which there is no Derby
> network server.
> Today this is solved in an ad-hoc way, for instance by using the current port
> minus one. When running tests in parallel, there is a chance that a port
> where there actually is a Derby network server listening is picked.
> As a start, I suggest that the bogus port is allocated to the last port in
> the port range configured for the run: baseport + MAX_PORTS_USED -1.
