Bottle seems to be the only web framework integration that sets the transaction name late, so errors that happen before that might not get associated to the correct segment name. We can't move the logic because we don't have enough information before that point. Restore the transaction setting logic in the event processor.

Missing route breaks event processor

Medium Severity

_get_transaction_name only catches RuntimeError, so a bound request with no route yet raises AttributeError on .rule or .name. That failure is new in the event processor and aborts it, so events from before_request hooks or unmatched routes lose request data and never receive a fallback transaction name.
