Nicholas Byrd commented on IO-497:
----------------------------------
Thanks for the update, [~ralfhauser]. I've retried the attached unit tests
using the latest commons-io 2.6-SNAPSHOT build. The "testStreamWithDelete" test
now passes, but the "testStreamWithDeleteAlternative" test still fails. So it
would seem that IO-512 is potentially only a partial fix at this point.

> Key: IO-497
> URL: https://issues.apache.org/jira/browse/IO-497
> Project: Commons IO
> Issue Type: Bug
> Components: Streams/Writers
> Affects Versions: 2.4
> Environment: unix-like operating systems where temporary disk storage
> is routinely purged; CentOS specifically
> Reporter: Nicholas Byrd
> Attachments: dfos-bug.tar.gz, dfos-bug-v2.tar.gz, example_stack.txt
>
>
> In the event that the Java temporary directory is deleted prior to the
> DeferredFileOutputStream trying to use it, the stream will throw one of two
> different IOExceptions (depending on how the Stream was constructed).
> This may sound like an unrealistic use-case at first, but it is legitimate as
> one of my company's applications encountered it after the underlying
> operating system (CentOS) automatically purged the contents of its tmp
> directory. (The application uses Commons FileUpload, which invokes
> DeferredFileOutputStream and does not handle the error itself.) Our current
> work-around is to restart the server when this happens, but we feel that the
> underlying library should perhaps be intelligent enough to recover from such
> an error.
> Additionally, it seems an awkward experience that two different errors are
> produced based on how the stream was constructed. One approach produces a
> FileNotFoundException while the other produces a plain IOException.
> A small maven project containing a single JUnit test that highlights the
> error will be attached (see
> [dfos-bug.tar.gz|https://issues.apache.org/jira/secure/attachment/12783728/dfos-bug.tar.gz]).
