Dag H. Wanvik updated DERBY-5492:
---------------------------------
Attachment: derby-5492-1.stat
derby-5492-1.diff
Uploading a patch which makes two changes:
- Construct a new AclEntry for the owner with all rights, and removed existing
ones (NTFS). This should handle the error seen in Oracle's regressions.
- For Solaris/ZFS and similar file systems which support both Posix file
attributes view and ACLs, don't touch the ACLs but stick to the Posix flags.
Rerunning regressions of NTFS, Solaris/ZFS and Linux.
> Restrictive file permissions: permissions removed also for owner on NTFS if
> Acl does not contain explicit entry for owner

> It turns out that the file owner does not necessarily get an explicit
> AclEntry; this depends on whether the created file has sufficient permissions
> already through, say, a permission for everybody to write. The present logic
> removes all AclEntries except those granted to the file's owner, erroneously
> presuming there would be such an entry always. This led to all AclEntries
> being removed.
