Tested against hyperborea.org (where I saw the spurious errors before) and against mosquito.wordpress.org (where it was originally trapped in the redirect loop). On the latter, with cookies disabled it correctly detects the loop and stops, and with cookies enabled it correctly reloads the first page, picking up the new 200 status instead of reusing the old 302 status, and shows the resulting page. Thanks for the last-minute fix! -- Kelson Vibber www.hyperborea.org

Let's see, if I've got the time conversions right, I usually leave work around 10:30 GMT (5:30pm PDT). I have DSL at home, so I can be online pretty much anytime this evening. I'll just make sure I check my email periodically. I'll probably go to sleep around 16:00 GMT (11pm PDT). Just to warn you, I won't have much time during work today, because we've had two servers die this morning. It looks like I'll be busy with that most of the day. If you do send a patch, I'll try to take a few minutes out to build it. -- Kelson Vibber www.hyperborea.org

Done. Attached goes the patch, and to the whole list just in case someone else wants to test it ;) --Apply over a clean rc3 tarball This fixes: * Stop button not going off after a redirection loop. * Multiple increases of the redirection hop counter (MTU). * A redirection after a redirection-loop inheriting the failure state. The patch has its debug messages enabled, just in case. As soon as you say it's OK, I'll remove the debugging messages, pack the 0.8.3 tarball and upload to the site for broader testing until the elusive Wednesday release. :-) -- Cheers Jorge.-

My ISP's proxy/router/gateway/whatever doesn't like to negotiate MTU!, but that's another story... Theoretical debugging is helping me now.

AFAIU, when the hops counter in Dillo detects a redirection Loop (whether real or false), and the next URL requested also gets a redirection code as answer, the latter is mistakenly treated as a redirection loop too. I'm polishing the patch... How much time will you be online. Or at what time (GMT) do you leave? (I want to upload 0.8.3 today for testing and to announce it on Wednesday morning). -- Cheers Jorge.-

Jorge Arellano Cid wrote: > Even more, the search is giving me no redirection but a plain > 200 OK answer. Look: Agh. I've got a caching plugin on the journal that saves the HTML output to cut down on database & processing time. It looks like it's caching the search results and just sending them as 200 instead of processing the pre-output part of the script. This explains the apparent inconsistency in which only the first hit triggered the spurious loop error: later hits picked up the cached copy with a 200 instead of a 302. Sorry about that. I've disabled it for now -- the only reason I really had it on was to deal with delays talking to Waypath, but they seem to be down half the time anyway. (In the long term I can set up a separate page to handle searches, and just tell it not to cache that page, but for now, this is simpler.) That should help with the debugging, since I won't have time to put together a test case today. -- Kelson Vibber www.hyperborea.org

The problem is that I can't reproduce the bug anymore! :P Even more, the search is giving me no redirection but a plain 200 OK answer. Look: <q> Nav_open_url: Url=>http://www.hyperborea.org/journal/index.php?s=dairy< Nav_open_url: redirect_level = 0 Connecting to 204.212.42.2 Header [io_len=116] HTTP/1.1 200 OK Date: Mon, 25 Oct 2004 13:35:00 GMT Server: Apache Connection: close Content-Type: text/html </q> I'll try on a dialup (bigger chance of getting small packets). A way to reproduce it would certainly help, but as it _seems_ to depend on the underlying granularity of packets, this may be hard to achieve... -- Cheers Jorge.-
