[thread_queue] Uncaught exception not delivered when Bugsnag.notify was previously called.

Describe the bug
Uncaught exception from a ruby script is not notified to bugsnag when:
- thread_queue is chosen as a delivery method
- a notification has been sent manually by calling Bugsnag.notify('my error') any time before the uncaught exception was raised.
Steps to reproduce
Configure Bugsnag with delivery method to thread_queue
Run:
Bugsnag.notify('This is notified correctly')
raise 'This is not notified with thread_queue'
Environment
- Bugsnag version: 6.24.0
- Ruby version: 2.7.6
- Bundle version: 2.3.4
- Rails version: 6.1.6.1
My understanding of the issue
Bugsnag::Delivery::ThreadQueue
registers a at_exit
to finish processing all notifications from the queue and then stop the thread that dequeue the notifications.
Bugsnag
register a at_exit
hook to deliver the unhandled error to Bugsnag::Delivery::ThreadQueue
This doesn't work when a notification was first sent with Bugsnag.notify
because afterward, raising an unhandled error will be processed by Bugsnag
at_exit
however Bugsnag::Delivery::ThreadQueue
at_exit
was already processed.
Hi @alx75 , thanks for reporting this. I've been able to reproduce the issue - we're going to take a look as soon as priorities allow.
Ok thanks. Easy workaround is to use synchronous delivery mode for scripts.
Hi @alx75 . Just a quick update, this does seem to be an issue for Ruby scripts that aren't running in a webserver.
We're looking to fix it in the next major version release, for now using the synchronous delivery looks like a good option as a workaround. We will update again once that has been released.
