[jira] Updated: (NUTCH-273) When a page is redirected, the original url is NOT updated.

Eelco Lempsink updated NUTCH-273:
---------------------------------

    Attachment: Fetcher.java-489586.diff

Let's not overcomplicate this issue.  At the moment, two different problems of different priorities are mixed in one issue.

Problem 1, blocker: The status of the URL causing the redirect isn't updated. Fixing that is not hard, attached is a one-liner patch.  Hopefully this can be applied soon.

Problem 2, minor: Should redirects be fetched immediately or not? One argument to fetch it immediately is that otherwise the redirectCount should be moved into the CrawlDatum (metadata).  If it's possible (in Jira) I suggest this problem should be split into a different issue.

> [Excerpt from maillist, sender: Andrzej Bialecki]
> When a page is redirected, the original url is NOT updated - so, CrawlDB will never know that a redirect occured, it won't even know that a fetch occured... This looks like a bug.
> In 0.7 this was recorded in the segment, and then it would affect the Page status during updatedb. It should do so 0.8, too...
