19:04:21 RRSAgent has joined #webperf 19:04:21 logging to http://www.w3.org/2015/10/21-webperf-irc 19:04:32 Present+ Yoav 19:04:34 Present+ Ilya 19:04:36 Present+ plh 19:04:55 agenda: https://lists.w3.org/Archives/Public/public-web-perf/2015Oct/0007.html 19:05:34 Topic: Clarify {transfer,encodedBody,decodedBody}size 19:05:42 - https://github.com/w3c/resource-timing/pull/41 19:06:07 Ilya: based on implementation feedback: clarifying what those values should report when you don't hit the network 19:06:22 ... need to address the feedback from Yoav 19:06:24 Pull: https://github.com/w3c/resource-timing/pull/41 19:06:37 Chair: Ilya 19:06:41 Meeting: Web Performance 19:06:45 rrsagent, make logs public-visible 19:07:10 Ilya: we can reuse the concepts from fetch 19:07:42 ... I'll make it clearer 19:08:13 Ilya: distinguishing between not allowed 19:08:24 ... if we don't pass the timing check algo, we report 0 19:08:34 Yoav: it might be a breaking change 19:08:54 ... what if the resource was actually 0? 19:09:09 ... the distinction with not allowed could be meaningful 19:09:35 Ilya: that's the behavior we have for other attributes (we report time 0) 19:11:06 ... if you hit the network, you'll never get non-0 for transferSize 19:12:34 Ilya: you can only know the transferSize if we pass the TAO header 19:12:43 ... if we don't, we always report 0 19:13:03 ... so if we report not allowed, then we may be saying too much 19:13:20 Yoav: I wonder what this would expose... TAO aren't user specific 19:14:12 ... the privacy concern would be if the server sends TAO headers depending on the user being logged in or not 19:14:20 ... not sure if TAO is used that way 19:15:09 Ilya: for consistency, if TAO disallows timing values, we report 0 19:15:41 Yoav: I agree but we should try to change this 19:16:25 Ilya: if we make nullable or undefined, we could break pages 19:16:59 ... we should look into this in a different issue 19:17:03 Yoav: I'll open one 19:17:11 Ilya: I'll keep it as 0 for now 19:17:50 ACTION: Yoav to open an issue on RT regarding TAO information and attributes 19:17:51 Created ACTION-161 - Open an issue on rt regarding tao information and attributes [on Yoav Weiss - due 2015-10-28]. 19:18:54 Ilya: with the current, if any of the requests failed during redirects, we set the attributes to 0. 19:19:57 Yoav: if the conditions don't match and we're not adding the http overhead.... I guess that's ok. 19:20:26 ACTION: Ilya to update pull 41 with network fetches 19:20:26 Created ACTION-162 - Update pull 41 with network fetches [on Ilya Grigorik - due 2015-10-28]. 19:22:35 FF bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1154309 19:22:39 Ilya: firefox is implementing right now. hoping Q4 for chrome but no one is committed to it. 19:23:11 Topic: Page Visibility 19:23:14 https://github.com/w3c/page-visibility/pull/16 19:23:50 Ilya: I was set to remove unloaded, but I found some issues 19:24:14 ... we define both visible and the visibilityState with different algorithms 19:24:21 ... so we should fix that 19:25:23 ... I'm proposing we drop the setting but run the algorithm instead 19:25:48 Yoav: I'm guessing the implementation will set the variable instead of running the algo 19:25:59 ... as long as we're identical in terms of functionality, we should be fine 19:26:31 Ilya: prerender is mandatory instead of optional 19:26:42 ... everyone implements it 19:26:56 ... Safari is very aggressive in using prerender 19:28:33 ... if you paste in the address bar, it will trigger prerendering based on predictions 19:29:02 yoav: as long as clearing the cache will also clear predictions, you should be fine 19:30:41 Ilya: next step is to keep circulating the PR 19:30:50 ... one outstanding change as well 19:33:19 plh: user interaction task source? 19:33:33 Ilya: wasn't sure about that one. will try to get Anne or Boris to look at it 19:34:17 Yoav: we need to separate issue for unloaded deprecation/removal 19:34:19 ILya: ok 19:34:33 ACTION: Ilya to open bug for unloaded in PV 19:34:33 Created ACTION-163 - Open bug for unloaded in pv [on Ilya Grigorik - due 2015-10-28]. 19:35:02 ACTION: Ilya: to add triggers for changing the value of visibility state 19:35:02 Created ACTION-164 - Add triggers for changing the value of visibility state [on Ilya Grigorik - due 2015-10-28]. 19:35:21 ACTION: Ilya to check the task source in PV 19:35:22 Created ACTION-165 - Check the task source in pv [on Ilya Grigorik - due 2015-10-28]. 19:35:35 Ilya: then we'll have to update resource hints 19:35:59 Topic: "Red warning" for TR/hr-time 19:37:17 Yoav: +1 to renaming idea 19:39:45 +1, let's discuss this more at TPAC as well 19:40:14 Topic: Drop prerenderSwitch from nav timing 2 19:40:36 Ilya: nobody implements prerenderSwitch 19:40:50 ... and it makes it tricky to understand when it is set 19:41:16 .... so not clear if it is necessary 19:44:40 Topic: clearMarks 19:44:59 Ilya: with performance observers, the buffer logic is expressed with simple JS 19:45:35 https://github.com/w3c/user-timing/pull/13#issuecomment-149985067 19:51:29 Topic: TPAC 19:51:36 https://docs.google.com/document/d/1IPM75UYlPPIPnr5uZMPYwb9EcOvquyWTo1uGqHeNafI/edit 20:25:09 rrsagent, generate minutes 20:25:09 I have made the request to generate http://www.w3.org/2015/10/21-webperf-minutes.html plh 20:33:35 regrets+ Todd 20:33:37 rrsagent, generate minutes 20:33:37 I have made the request to generate http://www.w3.org/2015/10/21-webperf-minutes.html plh 20:39:15 bkardell_ has joined #WebPerf 21:10:07 yoav has joined #webperf 21:16:04 yoav has joined #webperf 22:19:39 yoav has joined #webperf
