Proton messangers after fork
Greetings, I have a process that receives amqp messages using proton messenger in passive mode (inside select-based event loop) and sends replies back using second messenger in non-passive mode. I want to handle certain messages in a separate process instance. Normally I would just fork current process and do all necessary job in a child, but I have certain doubts about messenger connections. Should I just close corresponding file descriptors and free the messengers? Will this also affect messenger connections in parent? Will it be safe if I will just create a new messenger in a child (most probably in non-passive blocking mode) to send back reply messages? I am concerned about any possible implicit proton initializations: should I somehow re-initialize the library in child? Or is it more safe just to exec a different process in this case?

RE: qpid errors
The broker doesn't need to be run as a Windows service (but that's a perfectly good thing to do). The error below was likely because there is no \temp or \temp\qpidd.data directories and your account didn't have rights to create it. -Steve > -Original Message- > From: Suman.Patro-TRN [mailto:suman.patro-...@lntebg.com] > Sent: Tuesday, August 04, 2015 5:41 AM > To: users@qpid.apache.org > Subject: RE: qpid errors > > Hey Gordon, > Thanks a ton.

RE: qpid errors
Hey Gordon, Thanks a ton. The error got resolved. The broker in qpid 0.34 is named as qpidd.exe which needed to be run as a windows service.

I'm not sure why that is the case (I'm not a windows user, but hopefully someone more familiar with it will chip in with suggestions). There are two options you could use to avoid that: (1) use the no-data-dir option, which avoids needing a directory and (2) use the data-dir option to point at a valid directory the broker can use. qpidd.exe -h should give you all the available options. - To unsubscribe, e-mail: users-unsubscr...@qpid.apache.org For additional commands, e-mail: users-h...@qpid.apache.org Larsen & Toubro Limited www.larsentoubro.com This Email may contain confidential or privileged information for the intended recipient (s).
