Wouldn't have been confusing at all. 17:01:00 hello hello 17:01:02 Diziet: lol, yes 17:01:09 hihi 17:01:18 pad is at https://pad.riseup.net/p/tor-netteam-2022.1-keep 17:01:34 o/ 17:02:06 how are people doing with their boards: https://gitlab.torproject.org/groups/tpo/core/-/boards ? 17:02:44 yes 17:02:53 think so. 17:03:18 i don't see anything off either 17:03:32 dgoulet: anyting on releases? 17:03:50 nope 17:04:20 don't see anything incoming from other teams 17:04:39 i have a question for the arti gang 17:04:57 for phase 1.1.0 we have the bridge support goals and some PT support (maybe) 17:05:27 would it make sense for us to invite the anti-censorship team to one of our public arti meetings to sync with them on what arti means to them too? 17:06:08 we have a lot of tickets where we want to do things with PT's that we can't easily do today, but maybe with some thinking it would be easier to do in arti 17:07:12 makes sense; right now we have some discussion with meskio on one of the tickets, but there's no reason we can't expand it 17:07:27 doesn't seem like we're in a huge hurry imo since we don't start that milestone for a number of months... 17:07:31 sounds good. people OK if i just invite them and mention a bit what the topic could be there? 17:07:33 ya, agreed 17:07:34 ... so we could also wait till cecylia is back 17:07:36 it's more to get them thinking 17:07:45 hm, that might be a good idea 17:08:03 i'll add it on my todo for picking up in ~2 weeks then 17:08:34 very good 17:08:52 mikeperry: you can do s61 now 17:09:10 kk 17:10:01 last week I finished up the last fixups for the negotiation MR (https://gitlab.torproject.org/tpo/core/tor/-/merge_requests/525/). a couple threads need to be resolved 17:10:23 but otherwise I think it is ready. I ran some sims with it, and it still works as before 17:11:06 I believe I have also found the reason why the negotiation branch had more relay cell queue logs than pre-negotiation. it was basically a typo when migrating log patches. running a sim to confirm that. 17:11:30 nice 17:11:37 I think it's pretty much ready for merge 17:12:05 jnewsome has been working on making shadow support onion services in Shadow 17:12:46 there are some timeout issues that are visible from 0.4.6, which make it a bit difficult for tgen to let enough xfers complete, but these are not major blockers afaict 17:13:15 hm, interesting. wonder if that is something we should look into outside of s61 too? 17:13:19 jnewsome: did you want to talk about that, and/or hiro's utilization CDF branch? (hiro is out) 17:13:46 yeah, i filed an issue in the core tor component 17:13:55 yeah, it is basically a UX issue. it might be possible to fix fairly easily, but might also require some digging 17:14:01 pulling it up; i'll add to the pad 17:14:49 the tl;dr is that 20% of circuits decide to start using the old-school 60 second timeouts in some cases 17:14:57 but yeah have been chasing down tgen transfer error rates in onion services under shadow, which turns out to be due to timeouts while building the circuits, which turns out to be tor having long timeouts for individual extensions (i'm fuzzier on that last part) 17:15:15 hm, funky 17:15:17 possibly because of retry and additional-hop cases 17:15:39 I also stumbled across a tgen prng but last week that seems like it could affect results, but in small test sims doesn't seem to amke much difference 17:15:52 it was my impression we generally get occasional complaints about "odd timeout issues" with v3 onions, but it was always my impression they happen in specific periods (like under network attack and what not) 17:16:21 https://gitlab.torproject.org/tpo/core/tor/-/issues/40570 17:16:30 yeah, we perhaps did not have enough onion services running, as compared to the number of clients accessing them. that might have exacerbated it 17:17:11 thx jnewsome 17:17:17 jnewsome increased the number of onion services, and is also increasing the number of onion perfclients to get more data points 17:18:22 cool 17:18:35 dgoulet: the tl;dr for you is that we may be ready for an 0.4.7-alpha soon. probably as soon as we get some onion perf data 17:18:44 yeah. as for the utilization CDF branch I think it's nearly ready. some things are not as i'd prefer for maintainability, but i'd be ok with merging for expedience if we're blocked on it 17:18:47 I'm ready for this 17:18:52 do you know when hiro is back? 17:19:00 what's next steps for the merge of CC work? :-p a push? :-p 17:19:12 jnewsome: hiro is back tomorrow 17:19:29 we dont *need* the utilization CDFs asap. it is OK to get it a bit cleaner if you prefer 17:19:49 testing onion services for any obvious regressions with the new negotiation+congestion control is a bit more important 17:20:35 mikeperry: ok. i just merged the change I needed in tornettools. i'll launch a new baseline sim with onion services after this meeting 17:21:04 ahf: my read is that there is a unit test that nickm requested that he still needs to look over, and then there's some tickets I filed for the other threads. everything just needs to have "resolved" clicked afaict 17:21:29 cool! 17:21:32 very close 17:22:10 mikeperry: are you blocked on that at all? I wasn't likely to get to it soon but I can reshuffle my priorities if i need to 17:22:36 the earlier we can get this in the earlier we can get the alpha out 17:23:05 nickm: yeah, I think I did the stuff you asked. it would be good to get it wrapped up so we can start looking at an alpha 17:23:11 yeah we also have an important fix in the pipe for health team for this next alpha 17:24:09 in the next day or two we should have the sim results from onion services with congestion control to make that call 17:24:11 ok, i'll be on it today 17:24:51 sweet 17:24:57 do we have anything else for today's meeting? 17:25:16 juga,geko: anything from network-health and sbws? 17:25:23 nope 17:26:04 ah juga might still be on holiday 17:26:07 ok 17:26:10 bueno 17:26:13 let's call it then 17:26:27 thanks all for joining. tomorrow there is both big vpn meeting and all hands 17:26:33 see you all in #tor-dev or wherever we talk next 17:26:36 #endmeeting
