Andrzej Bialecki commented on NUTCH-153: ----------------------------------------- The timeout support has been added to OutlinkExtractor. It's difficult to set a single limit on the max. time for procesing, because for some formats the processing can legitimately take a long time. Additionally, Tika should better handle mime-type detection that the old Nutch code that it replaced. > TextParser is only supposed to parse plain text, but if given postscript, it > can take hours and then fail > --------------------------------------------------------------------------------------------------------- > > Key: NUTCH-153 > URL: https://issues.apache.org/jira/browse/NUTCH-153 > Project: Nutch > Issue Type: Bug > Components: fetcher > Affects Versions: 0.8 > Environment: all > Reporter: Paul Baclace > Fix For: 1.0.0 > > Attachments: TextParser.java.patch > > > If TextParser is given postscript, it can take hours and then fail. This can > be avoided with careful configuration, but if the server MIME type is wrong > and the basename of the URL has no "file extension", then the this parser > will take a long time and fail every time. > Analysis: The real problem is OutlinkExtractor.java as reported with bug > NUTCH-150, but the problem cannot be entirely addressed with that patch since > the first call to reg expr match() can take a long time, despite quantifier > limits. > Suggested fix: Reject files with "%!PS-Adobe" in the first 40 characters of > the file. > Actual experience has shown that for safety and fail-safe reasons, it is > worth protecting against GIGO directly in TextParse for this case, even > though the suggested fix is not a general solution. (A general solution > would be a timeout on match().) -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
