Version: Cortex 10.4.8.0

Description

When trying to create a reader for an empty cob file (and IECoreImage is loaded), stderr gets spammed with dozens of error messages like the following:

PtexReader error: read failed (EOF) PtexFile: /tmp/tmpznhadp6v.cob

While discussing the issue with @johnhaddon , we decided that simply skipping empty files would not be a good solution (as for some readers, those could be valid, and the potential of performance degradation), and that a better approach would be to try and get this sorted out on the OIIO side which is where the error messages are coming from.

Assigning this to @johnhaddon.

Steps to Reproduce

  1. Create an empty cob file (ex: /tmp/tmpznhadp6v.cob)
  2. Run the following code:
import IECore
import IECoreImage

r = IECore.Reader.create( "/data/share/ivani/tmpznhadp6v.cob" )

You should be spammed with error messages of this sort:

PtexReader error: read failed (EOF) PtexFile: /tmp/tmpznhadp6v.cob
