[jira] [Created] (PDFBOX-2999) Optimize COSStream scratch file usage

Timo Boehme created PDFBOX-2999:

             Summary: Optimize COSStream scratch file usage
                 Key: PDFBOX-2999
                 URL: https://issues.apache.org/jira/browse/PDFBOX-2999
             Project: PDFBox
          Issue Type: Improvement
          Components: PDModel
    Affects Versions: 2.0.0
            Reporter: Timo Boehme
            Assignee: Timo Boehme


The usage of scratch file buffers in COSStreams is quite sloppy. A never filled buffer is created in the beginning and existing buffers are discarded without being closed when a variant of {{createOutputStream}} is called. Furthermore it should be clarified if requesting an input stream without having created an output stream before is ok and if a returned input stream keeps valid after a new output stream is created (which is crucial for proper buffer-closing). 

This issue should resolve some of the shortcomings and document the expected or even required usage of COSStream.
