[jira] [Commented] (TIKA-1205) Allow PDFParser to fallback to other parser if there is an exception

["Hong-Thai Nguyen (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TIKA-1205?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13845398#comment-13845398 ] 

Hong-Thai Nguyen commented on TIKA-1205:
----------------------------------------

Just a (newbie) question, why limit only on PDFParser, not for any other parser ?
I agree that fallback is necessary when having exception. But, the worst case is infinitive loop happens when parsing a document.

For these two purposes, we would generalize to handle exception and timeout properly in a wrapper ?

> With TIKA-1201, there is now an option to use PDFBox's NonSequentialPDFParser instead of the traditional parser for parsing PDF files.  Following the description in PDFBOX-1199, it would be useful to allow fallback to the classic parser if NonSequentialPDFParser throws an IOException.  For the sake of symmetry, I propose a boolean useParserFallbackOnException parameter.  If this parameter is true, and if Tika's PDFParser is using the classic parser, Tika will fallback to the NonSequentialPDFParser if there is an IOException; if this parameter is true and if Tika's PDFParser is using the NonSequentialPDFParser it will fallback to the classic parser if there is an IOException.
> Many thanks to Hong-Thai for championing the addition of the added NonSequentialPDFParser capability in TIKA-1201, and many thanks to Timo for PDFBox's NonSequentialPDFParser (PDFBOX-1199)!
