Andreas Veithen updated SYNAPSE-212:
------------------------------------
Priority: Minor (was: Major)
Lowered priority from major to minor because temporary files are now deleted
when the corresponding TemporaryData objects are garbage collected. This is
still not optimal but should avoid resource exhaustion.
> XSLTMediator doesn't close/delete temporary files properly
> ----------------------------------------------------------
>
> Key: SYNAPSE-212
> URL: https://issues.apache.org/jira/browse/SYNAPSE-212
> Project: Synapse
> Issue Type: Bug
> Components: Core
> Affects Versions: 1.1, NIGHTLY
> Reporter: Andreas Veithen
> Priority: Minor
> Fix For: 1.2
>
>
> When a temporary file is used for the transformation result, XSLTMediator
> will read it back using the following instructions:
> StAXOMBuilder builder = new StAXOMBuilder(new
> FileInputStream(tempTargetFile));
> result = builder.getDocumentElement();
> Since Axiom constructs the XML tree on demand, this will actually not read
> the entire file but only a small part of it. Also, since nobody ever closes
> the input stream explicitly, the file will only be closed when the
> FileInputStream object is garbage collected.
> Immediately after the above instructions, XSLTMediator executes the following
> piece of code:
> boolean deleted = tempTargetFile.delete();
> if (!deleted) {
> tempTargetFile.deleteOnExit();
> }
> Since the file is still open at that moment, on Windows platforms, the delete
> operation will fail. Therefore the file will not be deleted until Synapse is
> shut down or restarted. On Unix systems, only the directory entry will be
> removed, but not the inode (and the content). On these systems, the file will
> be deleted by the OS when the file is closed, i.e. when the FileInputStream
> object is garbage collected.
> This problem is not easy to solve because the input stream can't be closed
> inside the mediate method (the whole purpose of having a temporary file being
> to allow streaming). It can only be closed (and deleted) safely once the
> sequence containing the XSLT mediation is completed and the message has been
> sent. Unfortunately, there seems to be no generic mechanism in Synapse to do
> this. Actually what would be needed is something similar to the flowComplete
> method in org.apache.axis2.engine.Handler.
