Ken Krugler commented on TIKA-522:
----------------------------------
My best guess is that the mime-type detection code is trying to read the
header, but the data isn't available yet (still being downloaded), so with the
partial data that it's got it winds up picking the wrong type.
Normally you wouldn't use Java's URL class to fetch pages like this - or at
least I wouldn't. I would use something like HttpClient, and pull down the
complete document, then pass that to Tika.
In any case, though, the mime-type detection code should be working, so I'm
going to assign this one to me to check out.

> Key: TIKA-522
> URL: https://issues.apache.org/jira/browse/TIKA-522
> Project: Tika
> Issue Type: Bug
> Components: parser
> Affects Versions: 0.7
> Environment: WIndows 7 x64, java v6.0.170.4, jdk1.6.0_21, Eclipse
> 20100617-1415
> Reporter: Dennis Adler

> I am crawling an SMB share. I've used the steps outlined in Tika samples to
> initialize; given a File object in f, my code is:
> parser = new AutoDetectParser();
> context.set(Parser.class, parser);
> // Get the URL
> URL url = f.toURI().toURL();
> // Extract Metadata
> Metadata metadata = new Metadata();
> BodyContentHandler handler = new BodyContentHandler(-1); // -1 =
> infinite size for XML string buffer (per file)
> // Get the input stream
> InputStream input = MetadataHelper.getInputStream(url, metadata);
> // Parse the document
> parser.parse(input, handler, metadata, context);
> If I place a breakpoint right after the parser.parse invoke, I find the
> metadata calling my input out as an Audio file. If I try to debug the parse
> steps, it correctly tags it as Text/HTML. Seems like a timing-related problem.
> I have a half-baked workaround: I invoke Thread.sleep(5000) just after the
> context.set invoke... in 3 sequential test runs that works fine. Problem is,
> this was working fine several days ago without that (perhaps my computer was
> busy with other things and the timing issue did not pop up then).
> I have downloade and am building today's 0.8 from svn to see if that helps,
> though I am concerned about the impacts to the rest of my testing if I have
> to swtich to 0.8. Just understanding what was going on would be a huge help :)
> * UPDATE * I was able to repro this once under the debugger. MimeTypes.detect
> invokes org.apache.tika.mime.MimeTypes.getMimeType on the input stream to
> determine the Mime Type based on the first 8k of data. I did not trace into
> getMimeType, but did see it return "audio/mpeg" on an HTML file one time, and
> "text/html" most others. I can supply the HTML file if desired.
