[jira] [Updated] (CODEC-121) QuotedPrintableCodec does not support soft line break per the 'quoted-printable' example on Wikipedia

["Thomas Neidhart (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CODEC-121?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Thomas Neidhart updated CODEC-121:
----------------------------------
    Attachment: CODEC-121_v2.patch

I have revisited my original patch and created a new one that should be backwards compatible:

 * add a new strict mode parameter to the codec: if strict=true implement the full ruleset of the quoted-printable spec
 * decode can handle softline breaks regardless of the strict parameter, this should be backwards compatible, previously an input with soft line breaks resulting in an exception

Would be nice to still include it in 1.10.

> Writing a unit test I discovered that the example Wikipedia uses for quoted-printable data does not decode but instead throws an exception.  
> Their example is here:  http://en.wikipedia.org/wiki/Quoted-printable#Example
> test:
>   String qpdata   = "If you believe that truth=3Dbeauty, then surely=20=\r\n" +
> 		    "mathematics is the most beautiful branch of philosophy.";
>   String expected = "If you believe that truth=beauty, then surely " +
> 		    "mathematics is the most beautiful branch of philosophy.";
>   assertEquals( expected,  new QuotedPrintableCodec().decode(qpdata) );
> I suppose I could fix if you like but currently I'm not a registered developer.
