Fix Version/s: (was: Graduating from the Incubator)
> Several defects in robots exclusion protocol (robots.txt) implementation
> ------------------------------------------------------------------------
>
> Key: DROIDS-109
> URL: https://issues.apache.org/jira/browse/DROIDS-109
> Project: Droids
> Issue Type: Bug
> Components: core, norobots
> Affects Versions: 0.0.2
> Reporter: Fuad Efendi
> Original Estimate: 672h
> Remaining Estimate: 672h
>
> 1. Googlebot and many others support query part rules; Droids currently
> supports only URI.getPath() (without query part)
> 2. %2F represents "/" (slash) character inside a path; it shouldn't be
> decoded before applying rule
> 3. Double decoding is used by NoRobotClient.isUrlAllowed(URI uri) (method
> body; baseURI.getPath(); returns decoded string; then we call another
> URLDecoder.decode(path, US_ASCII);
> 4. URLDecoder.decode(path, US_ASCII); - UTF-8 must be used!
> 5. The longest matching directive path (not including wildcard expansion)
> should be the one applied to any page URL
> 6. Wildcard characters should be recognized
> 7. Sitemaps
> 8. Crawl rate
> 9. BOM sequence is not removed before processing robots.txt
> (http://unicode.org/faq/utf_bom.html, bytes: 0xEF 0xBB 0xBF
> and most probably many more defects (Nutch & BIXO haven't done it in-full
> yet). I am working on it right now...

> http://en.wikipedia.org/wiki/Uniform_Resource_Identifier
> http://www.searchtools.com/robots/robots-txt.html
> http://en.wikipedia.org/wiki/Robots.txt
> Referenced (even by Google!) http://www.robotstxt.org/wc/norobots-rfc.html
> seems at least outdated...
> Proper reference: http://www.robotstxt.org/norobots-rfc.txt (1996).
> We need WIKI page explaining all rules implemented by Droids; hopefully it
> will become unofficial standard.
