New submission from Simon Naish: When attempting to use a config file with logging to set up a series of loggers in a script, when running on windows, if the config file name starts with an 'r' then the script fails with the following error:-
File "C:\Users\simon\Documents\python dev\RepositoryChainPkg\FileLogger.py", line 45, in fileConfig logging.config.fileConfig(FileLogger.CONF_FILENAME) File "C:\Python27\lib\logging\config.py", line 78, in fileConfig handlers = _install_handlers(cp, formatters) File "C:\Python27\lib\logging\config.py", line 156, in _install_handlers h = klass(*args) File "C:\Python27\lib\logging\handlers.py", line 117, in __init__ BaseRotatingHandler.__init__(self, filename, mode, encoding, delay) File "C:\Python27\lib\logging\handlers.py", line 64, in __init__ logging.FileHandler.__init__(self, filename, mode, encoding, delay) File "C:\Python27\lib\logging\__init__.py", line 902, in __init__ StreamHandler.__init__(self, self._open()) File "C:\Python27\lib\logging\__init__.py", line 925, in _open stream = open(self.baseFilename, self.mode) IOError: [Errno 22] invalid mode ('a') or filename: 'C:\\Users\\simon\repositoryChainLogging\repo_log.log' The same script works perfectly on linux and solaris. Points to note, the config filename (and path) is listed in the error as:- 'C:\\Users\\simon\repositoryChainLogging\repo_log.log' Yet when it is passed to logging\config.py as parameter fname in function fileConfig it is:- b'C:\\Users\\simon\\repositoryChainLogging\\repo_log.conf' In other words the path passed in by the script is correctly seperated and escaped by os.path functions. However in _install_handlers (line 133 of logging\config.py) the args = eval(args, vars(logging))line (154) gets the path back in this tuple:- (b'C:\\Users\\snaish.BRIGHTON\repositoryChainLogging\repo_log.log', b'a', 131072, 10) Where it has clearly lost some of the escaping, rendering the path useless, since \r is a control character, and therefore invalidates the path. Therefore at the moment it is impossible to use logging config fiels beginning with r onw windows at the moment. ---------- components: Library (Lib) messages: 202422 nosy: 51m0n priority: normal severity: normal status: open title: logger.config.fileConfig cant cope with files starting with an 'r' on windows versions: Python 2.7 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue19528> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
