Logging: Unicode Error #57441
Comments
In changeset fe6be0426e0d the format() method was changed. Unfortunately it does not catch all unicode decode errors. I think line 482 of logging/init.py should be modified: s = s + record.exc_text.decode(sys.getfilesystemencoding(), 'replace') http://hg.python.org/cpython/file/f35514dfadf8/Lib/logging/__init__.py#l482 Here is the stacktrace we get:
{{{

Can you tell me what the actual data was which failed to be decoded? Is there more than one encoding in effect (e.g. one for the filesystem, and another for the other data in the exception being logged)? |
I attached a testcase (unicodedecodeerror-in-logging.py). If the filesystemencoding is UTF-8 and the source code is encoded in latin1, then the logging fails. It happens because there is a German umlaut in the comment behind 1/0. I added 'replace' to the decode() in __init__.py and the it works. The German umlaut gets displayed as inverted question mark. But this is better than no logging message. |
