Subject [jira] [Updated] (SOLR-2480) Text extraction of password protected files
Date Sat, 14 May 2011 14:51:47 GMT


Koji Sekiguchi updated SOLR-2480:

    Attachment: SOLR-2480.patch

New patch.

According to custom, ExtractingRequestHandlerTest class should be at o.a.s.handler.extraction,
but curiously it was o.a.s.handler. I corrected it in this patch.

>          Components: contrib - Solr Cell (Tika extraction)
>    Affects Versions: 1.4.1, 3.1

> Proposal:
> There are password-protected files. PDF, Office documents in 2007 format/97 format.
> These files are posted using SolrCell.
> We do not have to read these files if we do not know the reading password of files.
> So, these files may not be extracted text.
> My requirement is that these files should be processed normally without extracting text,
and without throwing exception.
> This background:
> Now, when you post a password-protected file, solr returns 500 server error.
> Solr catches the error in ExtractingDocumentLoader and throws TikException.
> I use ManifoldCF.
> If the solr server responds 500, ManifoldCF judge is that "this
> document should be retried because I have absolutely no idea what
> happened".
> And it attempts to retry posting many times without getting the password.
> In the other case, my customer posts the files with embedded images.
> Sometimes it seems that solr throws TikaException of unknown cause.
> He wants to post just metadata without extracting text, but makes him stop posting by
the exception.
