New submission from David Ruggles <thedavidfac...@gmail.com>:
ISSUE: if you add a formatter to QueueHandler any subsequently added handlers will get the formatting added to QueueHandler CAUSE: as best as I can tell, the code here: https://github.com/python/cpython/blob/d586ccb04f79863c819b212ec5b9d873964078e4/Lib/logging/handlers.py#L1380 is modifying the record object so when it get passed to the next handler here: https://github.com/python/cpython/blob/d586ccb04f79863c819b212ec5b9d873964078e4/Lib/logging/__init__.py#L1656 it includes the formatting applied by the QueueHandler's formatter. I worked around this issue by moving my formatter from the QueueHandler to the QueueListener I've attached a simple example of the issue NOTE: I marked this as Python 3.7 because that's what I'm using, but I looked at github and the code is in master so I assume this affects 3.8 too. ---------- components: Library (Lib) files: queuehandler_bug.py messages: 333526 nosy: David Ruggles priority: normal severity: normal status: open title: QueueHandler formating affects other handlers versions: Python 3.7 Added file: https://bugs.python.org/file48044/queuehandler_bug.py _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue35726> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
