Uninitialised tracer raises when not being initialised about beeline-python

[tredman]

Do you want to avoid calling beeline.init at all, or are you just trying to avoid sending events to honeycomb in a dev environment?

For the latter: You could initialize the beeline with dummy values for writekey and dataset, then override the transmission to send to stderr. There's an example here: https://docs.honeycomb.io/beeline/python/#customizing-event-transmission

If you want to avoid writing anything you could also override the transmitter to write to /dev/null.

import beeline
import libhoney
import os
from libhoney.transmission import FileTransmission

beeline.init(writekey='yourwritekey', transmission_impl=FileTransmission(output=open(os.devnull, 'w'))

(we really should add a NullTransmission to libhoney, for when absolutely no output is desired.)

If you are trying to avoid calling beeline.init at all - I think we would need to update beeline.tracer to work in the case that it's not initialized. Funnily enough, in version 2.4.1, we added a traced function wrapper that does work if the beeline is not initialized - you might try that if you just want to use the wrapper. Docs are here: https://docs.honeycomb.io/beeline/python/#using-traces - see the section "using a decorator".

Let me know if this helps.

Sorry for not explaining the problem clearly enough. I am trying to do something different actually. I am trying to avoid the need to call beeline.init() in some environments and still have decorated functions work properly.

Funnily enough, in version 2.4.1, we added a traced function wrapper that does work if the beeline is not initialized - you might try that if you just want to use the wrapper. Docs are here: https://docs.honeycomb.io/beeline/python/#using-traces - see the section "using a decorator".

It seems to be exactly what I need! Will upgrade now (running 2.3.0) and remove my homebrew decorators.

Btw #53 will fix the issue with the context manager. When #54 lands I'll cut version 2.4.4 with the changes.
