#1377 closed defect (wontfix)

"tahoe start" claims to have started when it didn't

Description (last modified by daira)

The problem that I reported in #1376 was caused by the gateway failing to start due to the port number already being taken. From its twistd.log:

2011-03-11 11:57:37-0500 [-]   File "/System/Library/Frameworks/Python.framework/Versions/2.6/Extras/lib/python/twisted/internet/tcp.py", line 858, in startListening
2011-03-11 11:57:37-0500 [-]     raise CannotListenError, (self.interface, self.port, le)
2011-03-11 11:57:37-0500 [-] twisted.internet.error.CannotListenError: Couldn't listen on any:9996: [Errno 48] Address already in use.

Looking back through my screen buffer, I see that it misled me into thinking that it had started:

$ tahoe start .
STARTING '/Users/zooko/tmp/d/tmp_create'
$

stercor had this problem after accidentally configuring Apache to listen on port 3456, and I've also had it once or twice. Putting it into milestone 1.11.

Zancas just had this problem, and I've had it several times since the last comment. I'm increasingly annoyed by it.

Description modified (diff)

We're at a hack fest in Berlin and a new user is also having this problem. Now I'm annoyed enough to fix it :-)

Summary changed from "tahoe start" claims to have started when it didn't (due to port number conflict) to "tahoe start" claims to have started when it didn't

Hey, does http://twistedmatrix.com/trac/ticket/823 fix this?? Or at least help?

http://twistedmatrix.com/trac/ticket/823 has been fixed, so if it fixes this ticket, or at least makes it easier for us to fix this ticket, then someone should revisit this ticket.

http://twistedmatrix.com/trac/ticket/823 makes twistd wait by default, so there is nothing we need to do in Tahoe-LAFS to enable it. We should test whether it actually helps in cases such as #2147.
