[jira] Updated: (QPID-2041) failed update to the
Base64MD5PasswordFilePrincipalDatabase on disk may go unnoticed, preventing
broker restart
[ https://issues.apache.org/jira/browse/QPID-2041?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Robbie Gemmell updated QPID-2041:
---------------------------------
Description:
failed update to the MD5PasswordFilePrincipalDatabase on disk may go unnoticed, preventing broker restart
Certain use of the File.renameTo() function is not accompanied by a check of the boolean result, meaning a failed rename can leave the file in the wrong location, but the cached nature of the Base64MD5PasswordFilePrincipalDatabase masks the failure until another operation is attempted upon it that needs the output of the previously failed update. This has been observed in a situation where the OS Temp dir is on one file system, and the broker configuration is on another, which caused the rename to fail unnoticed.
