Wanvik > Assignee: Dag H. Wanvik > Attachments: derby-5363-basic-1.diff, derby-5363-basic-1.stat, > derby-5363-basic-2.diff, derby-5363-basic-2.stat, permission-5.diff, > permission-5.stat, permission-6.diff, permission-6.stat, property-table.png, > z.sql > > > Before Java 6, files created by Derby would have the default > permissions of the operating system context. Under Unix, this would > depend on the effective umask of the process that started the Java VM. > In Java 6 and 7, there are methods available that allows tightening up this > (File.setReadable, setWritable), making it less likely that somebody > would accidentally run Derby with a too lenient default. > I suggest we take advantage of this, and let Derby by default (in Java > 6 and higher) limit the visibility to the OS user that starts the VM, > e.g. on Unix this would be equivalent to running with umask 0077. More > secure by default is good, I think. > We could have a flag, e.g. "derby.storage.useDefaultFilePermissions" > that when set to true, would give the old behavior. -- This message is automatically generated by JIRA.
