Tue Dec 1 05:32:17 2015  briang:dcarlin, zwoop , were you guys looking for me about znc related stuff?
Tue Dec 1 05:32:41 2015  briang:also, maybe we should setup fail2ban on the znc server, does it get scanned / screwed with frequently?

Tue Dec 1 09:29:56 2015  felicity:zwoop: is that the SWR-in-core bits? how much of that is actually finished/usable so far?
Tue Dec 1 09:56:15 2015  felicity:does ASAN find leaks?
Tue Dec 1 09:59:57 2015  felicity:oh... not on OS X :(

Tue Dec 1 10:04:44 2015  Humbedooh:\ask: Ashburn is going away, company went bankrupt it seems - so meh :p
Tue Dec 1 10:41:04 2015  briang:felicity, you might consider building running on linux solely for that purpose though
Tue Dec 1 10:47:49 2015  felicity:mmh... i found leaks(1) in OS X, but i'm not sure it's working. it gives the wrong line number for a start
Tue Dec 1 10:50:35 2015  felicity:does this callstack look like an actual leak? http://dpaste.com/32VR2VA
Tue Dec 1 11:08:55 2015  felicity:ok, weird, now TS has decided to just not start with 'failed to connect management socket'

Tue Dec 1 16:05:35 2015  zwoop:felicity we should check with sudheerv , but yes, at least some of it should work well, if I understand, it implements stale-while-revalidate well, but not stale-if-error
Tue Dec 1 16:05:41 2015  zwoop:sudheerv ^ ? :)
Tue Dec 1 16:06:42 2015  sudheerv:zwoop: are you referring to the open write fail action feature?
Tue Dec 1 16:07:33 2015  sudheerv:sorry, my adium client has been acting up and i don't seem to find all of the prev messages
Tue Dec 1 16:12:09 2015  sudheerv:felicity: zwoop might be referring to https://cwiki.apache.org/confluence/display/TS/Presentations+-+2015?preview=/56066455/61328981/Stale%20While%20Revalidate%20(Open%20Write%20Fail)%20Copy.pptx.pdf
Tue Dec 1 16:12:27 2015  sudheerv:the open write fail action feature "almost" supports SWR already in 6.0
Tue Dec 1 16:12:39 2015  sudheerv:the missing parts are the RFC header checking
Tue Dec 1 16:12:56 2015  sudheerv:and the very first request not returning the stale copy
Tue Dec 1 16:13:15 2015  sudheerv:these two are in my to-do list..hoping to do them before the next release is available
Tue Dec 1 16:13:19 2015  jpeach:felicity: leaks(1) has always been reliable in my experience
Tue Dec 1 16:24:42 2015  felicity:hm, we already use open_write_fail_action, but we specifically want to avoid queueing requests to the origin when the cache expires, and we need stale-if-error as well
Tue Dec 1 16:24:48 2015  felicity:which as i understand it, open_write_fail can't do
Tue Dec 1 16:25:00 2015  felicity:(yet?)
Tue Dec 1 16:25:03 2015  sudheerv:felicity: yeah, the SIE - haven't thought about that
Tue Dec 1 16:25:25 2015  sudheerv:but, avoiding the queueing of reqs should be working with open write fail action?
Tue Dec 1 16:25:39 2015  felicity:this is an ESI include on every page, so we can't have every page load help up while the resource is revalidated with the backend, which can take a few seconds
Tue Dec 1 16:26:48 2015  sudheerv:yeah, doesn't open write fail action do that?
Tue Dec 1 16:26:58 2015  sudheerv:i mean, it does return the stale copy, whenever available?
