Vinay Sajip <vinay_sa...@yahoo.co.uk> added the comment: ConcurrentLogHandler is for multiple *processes* writing to the same file, not multiple threads in a single process. Python logging does not support multiple processes writing to the same file because there is no portable IPC locking across all platforms supported by Python. ConcurrentLogHandler uses portalocker to achieve interprocess synchronization, and there is no equivalent mechanism which is part of the Python stdlib. AFAIK portalocker works on Windows and Linux - I'm not sure about other platforms.
Python logging *does* support multiple threads in a single process writing to the same file, which is why I asked Robert if it was definitely a single-process environment he was working in. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue4749> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
