Timo Boehme updated PDFBOX-1333:
--------------------------------
Attachment: 2012-06-06_BaseParser_streamFallBack.patch
patch for BaseParser which tests that stream parsing using length value reaches
'endstream', if not, parsed data are pushed back and stream is parsed again
using scanning for 'endstream';
this patch also increases push back buffer to 64kB in order to be able to hold
larger streams; size can be modified using system property
org.apache.pdfbox.baseParser.pushBackSize
> Stream parsing of BaseParser should fall back to scanning if length value is
> wrong

> Key: PDFBOX-1333
> URL: https://issues.apache.org/jira/browse/PDFBOX-1333
> Project: PDFBox
> Issue Type: Improvement
> Components: Parsing
> Affects Versions: 1.7.0
> Reporter: Timo Boehme
> Assignee: Timo Boehme
> Fix For: 1.8.0

> In 1.7.0 stream parsing in BaseParser was optimized to use length value if
> available. The advantage is faster parsing and independence of 'endstream'
> bytes sequences in stream. However the disadvantage is that streams with
> wrong length values cannot be parsed anymore (see PDFBOX-1331).
> To solve this we should check if 'endstream' is really reached when using
> length value and if not, fall back to 'old' behavior of reading stream until
> 'endstream' is found.
