1) get poky, source environment
2) issue command 'bitbake man'
3) add in local.conf: PRSERV_HOST = "127.0.0.1:1234"
4) issue command 'bitbake man'

Notice error:
ERROR: PRservice 127.0.0.1:1234 not available

5) again, issue the command 'bitbake man'

Notice error:
ERROR: Only one copy of bitbake should be run against a build directory

Comment 1 Richard Purdie 2013-10-04 14:51:22 UTC

I tried this on the revision of poky mentioned and on master and could not reproduce it. Can you double check this reproduces please?

Comment 2 Stoicescu Cornel 2013-10-04 15:21:05 UTC

New steps to reproduce:
1) Set up 2 poky environments
2) in the first poky environment issue command: bitbake-prserv --start
3) in the second poky environment add in local.conf: PRSERV_HOST = "127.0.0.1:8585"
4) in the second poky environment, issue command: bitbake man
     - you can cancel the build once is starts executing tasks
5) in the first poky environment, issue command: bitbake-prserv --stop
6) in the second poky environment issue command: bitbake man
     - notice (correct) error:
 ERROR: PRservice 127.0.0.1:8585 not available
6) in the second poky environment, issue again the command: bitbake man
     - notice error:
ERROR: Only one copy of bitbake should be run against a build directory

Comment 3 valentin 2013-10-04 15:25:40 UTC

Hi Richard,
I could also reproduce this on my tree by sending SIGINT (CTRL+C) while running the first "bitbake man". Then add the server address in local.conf and run "bitbake man" again.
The problem seems to be that shutdown() from cooker.py returns premature because self.toparse is not initialized.
Do you have any sugestions of how to fix this problem?

Comment 4 valentin 2013-10-17 11:10:56 UTC

This issue doesn't reproduce on master anymore due to Richard's fix: 3ca820de91c2456a1b1c44022072f6ce7aa21344.
Thanks for the help Richard!
