http://nagoya.apache.org/bugzilla/show_bug.cgi?id=22894 Single backslash not accepted in File param value Summary: Single backslash not accepted in File param value Product: Log4j Version: 1.2 Platform: PC OS/Version: All Status: NEW Severity: Normal Priority: Other Component: Configurator AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] If you enter a filepath with single backslashes, the backslashes will be ignored ( or converted to special characters such as newline or tab, depending on the character after the backslash ). So, for example, a filepath of: C:\MyDirectory\MyLog.txt will end up as the file: MyDirectoryMyLog.txt in the current folder. I looked at the log4j code and discovered that *all* parameter values are processed via the method org.apache.log4j.helpers.OptionConverter.convertSpecialChars(). This method treats backslashes as an escape character, to support such things as \t for tab and \n for newline. A single backslash without an appropriate following character is quietly consumed. Since tabs, newlines, and other special characters are not valid in filepaths, it would be nice if parameter values of type "File" were not processed via the convertSpecialChars() method. Since double backslashes should be supported, too, for backward compatibility, I would suggest replacing the invocation of convertSpecialChars() with an invocation of a new method that simply replaces double backslashes with single backslashes, in the case where the param is of type "File". In this way, both double backslashes and single backslashes would be supported in filenames. Thanks, Tom Caulkins Sr. Systems Developer SAS Institute Inc.
