Hi
actually it would help with our original case (that was caused by
incorrect file rights on a Unix box). However, the test case I wrote do
not use access rights but instead just keeps the open for writes as I
didn't want to fiddle with the access rights from the unit test :-)

Might actually work for this special case, but I would not want to
make the code more complicated unless really needed. As you say that
it does not really help with your problem I would rather vote against
introducing it.
Thoughs?

If that test (File.canWrite()) was executed during deleteResource() and
if failing it would directly throw an Exception. That would mean that we
get the exception before the commit. Now, this won't fix my test case as
canWrite() doesn't detect write-locked files but I guess it could work
for cases where you do not have the necessary file access. What do you
think?

Yes, I think so. But if you tried it would not fail before commit.

Hi
well, I'm not sure how to do this either. Could File.canWrite() be an
indication?

You are right. It would be desirable to make it fail as soon as
possible. This would mean, however, that you touch the original file
as soon as you try to delete it and not only when you commit the
transaction. But the philosophy if this transactional implementation
is not to touch the original file before commit. There are other
implementations imaginable that make all the modifications on the
original file but keep a backup for rollback, though.
Thus, in short, the answer is that I do not know how to check this
earlier given this implementation, but with others it would be
possible.
But, maybe, I am just not smart enough to find a solution ;)
