Description Juro Bystricky 2019-04-05 15:12:11 UTC 
My HOSTTOOLS were missing "chrpath", so an error message was expected. However, not like this:


ERROR: Unable to start bitbake server (None)
ERROR: Server log for this session (/home/juro/yocto/poky/build2-repro-minimal-x86_64-2019-04-04/bitbake-cookerdaemon.log):

During handling of the above exception, another exception occurred:

Comment 1 Robert Yang 2019-04-29 08:28:18 UTC 
Hi RP,

I think that double exceptions are acceptable unless it loses error message? For this case, the error message is kept. What's your opinion, please ?
Comment 2 Richard Purdie 2019-05-01 07:09:40 UTC 
The double exception is confusing to the user. The system printed a real error so it shouldn't be printing an exception at all in this case. One of the points of bb.BBHandledException is to avoid tracebacks as there should have been a usable error shown to the user already.
