[BUG?] 'ResourceWarning: unclosed file <_io.BufferedReader name=xx>' while parsing recipes

[BUG?] 'ResourceWarning: unclosed file <_io.BufferedReader name=xx>' while parsing recipes

[Claudius Heine]

Hi,

I get those warnings in my log:

     Parsing recipes...WARNING: 
/builds/ebsy/debian/isar/meta-isar/recipes-core/images/isar-image-base.bb: 
<string>:15: ResourceWarning: unclosed file <_io.BufferedReader name=32>

     WARNING: 
/builds/ebsy/debian/isar/meta-isar/recipes-core/images/isar-image-debug.bb: 
<string>:15: ResourceWarning: unclosed file <_io.BufferedReader name=30>

They don't seem to have any effect, but are annoying. Does anyone know 
what those mean and how to fix them? I guess they start appearing on a 
bitbake update. Should they be investigated?

Thanks,
Claudius

and made the same observations, asked ourselfs the same questions.
I also think it came with the bitbake update and i think it should be
investigated and resolved.

I'm getting even more warnings these days, right after finishing the build:

Exception ignored when trying to write to the signal wakeup fd:
BlockingIOError: [Errno 11] Resource temporarily unavailable

Yes, agreed. Maybe the first try should be updating bitbake and check if the 
issue persists. Or check if its git history suggests that something was changed 
in this direction.

Just browsed some bitbake commits for other reasons:

http://git.openembedded.org/bitbake/commit/?id=afee3f594e1510051a0b18e430e92549caf72fa2

Looks like an update will do it.

I am not sure. They fix an unclosed socket, but our error is an unclosed 
file. There exception occures with '.../lib/bb/main.py:481' ours 
'...images/isar-image-debug.bb'.

I guess that it is a similar issue this patch fixes, but IMO that one 
doesn't look like it fixes our problem.

Anyway thanks for looking that up!
Claudius
