Description Paul Eggleton 2018-08-23 21:25:17 UTC 
If the bitbake server fails to start (e.g. because of a sanity test failure when processing the configuration) and there is no TTY (e.g. when running inside Docker without -t) then the last 10 lines of bitbake-cookerdaemon.log will not be printed. This appears to be because the start marker that we need to figure out where the last server's messages start in the logfile does not get written to the file when there is no TTY.

Log when there is no TTY:
https://travis-ci.org/crops/poky-container/jobs/419770906

Log when there is a TTY:
https://travis-ci.org/rewitt1/poky-container/jobs/419847827

(FYI the reason there is no TTY set normally for this container is because if there is one then you get progress/timer cruft in the output).

We've seen this on jenkins and on buildbot on our autobuilder too. Its confusing as the error doesn't show in the logs and the user gets confused.

I tried:

$ echo 'HOSTTOOLS += \"hello\"' >> conf/local.conf

$ nohup bitbake -p

It works as expected, there is a bitbake-cookerdaemon.log, and the last 10 logs printed.

I also tried docke run <image> without -t, it also worked as expected.

I suspect there is no bitbake-cookerdaemon.log when the error happened.

I need more info to go on this work:
* Do you still get the errors recently ?
* Would you please provide detailed steps on how to reproduce it?

I think that what can I do now is print an info when there is no bitbake-cookerdaemon.log

I just did a bisect and it looks like this issue was fixed with 74feaddda3b7cd5b3ab18d2f25bf5ef9581c9c47.
