Emil Zegers commented on TIKA-1770:
-----------------------------------
Wrong recognition of text files still happens with Tika 2.4.1. Took me a while
to understand what was going on and then I found the bug report. Curious to
understand what would be needed to fix this. Happy user of Tika but I don't
know the code base yet.
> AutoDetectParser wrongly detects plain text as images/audio
> -----------------------------------------------------------

> Key: TIKA-1770
> URL: https://issues.apache.org/jira/browse/TIKA-1770
> Project: Tika
> Issue Type: Bug
> Components: parser
> Affects Versions: 1.10
> Environment: OS independent (tested on both Windows, MAC OS)
> Reporter: Ziqi
> Priority: Minor
> Attachments: the-acl-rd-tec_chunk_10228.txt,
> the-acl-rd-tec_chunk_15.txt, the-acl-rd-tec_chunk_9113.txt
>
>
> AutoDetectParser fails to recognize certain plain-text files as plain text.
> In the attachment are three testing files, as you can see they are all plain
> text.
> The following code is used for testing:
> ————————
> AutoDetectParser parser = new AutoDetectParser();
> for (File f : new File("path").listFiles()) {
> InputStream in = new BufferedInputStream(new
> FileInputStream(f.toString()));
> BodyContentHandler handler = new BodyContentHandler(-1);
> Metadata metadata = new Metadata();
> try {
> parser.parse(in, handler, metadata);
> String content = handler.toString();
> System.out.println(metadata); //line A
> }catch (Exception e){
> e.printStackTrace();
> }
> }
> ————————
> for the three testing files, line A prints the following:
> X-Parsed-By=org.apache.tika.parser.EmptyParser
> Content-Type=image/x-portable-bitmap
> X-Parsed-By=org.apache.tika.parser.DefaultParser
> X-Parsed-By=org.apache.tika.parser.mp3.Mp3Parser xmpDM:audioCompressor=MP3
> Content-Type=audio/mpeg
> X-Parsed-By=org.apache.tika.parser.EmptyParser
> Content-Type=image/x-portable-bitmap
> And as a result, variable "content" is always empty.
