relaybot 13apophis: ты не понял о чем я спрашивал или я не так обьяснил .. проехали

orignal задача считать правильно RTT

relaybot 13apophis: я обратил внимание, потому и спросил ...

relaybot 13apophis: если уперлись в динамический расчет для РТТ.. вит что я хотел знать

orignal ну он довольно сложный

Vort "<onon1> RTT меняется слишком быстро, нет смысла его куда-то передавать." - как помнишь, при запросе к веб серверу, данных для надёжного расчёта RTT собирается мало. было бы удобно соседним запросом к тому же серверу обновить RTT первого запр

Vort оса

Vort apophis: на принимающей стороне RTT используется для определения того, насколько часто слать ACK`и

Vort на отправляющей стороне - да, для перепосылок

Vort "apophis: метрика крайне ненадежная" - какая тогда надёжная?

Vort github.com/Vort/i2pd/commit/cf77be0eeb403155a1b3c440f3709add13e6f001

Vort часть глюков при тестировании на локалхосте происходит из-за лимита частоты отправки ACK`ов: MIN_SEND_ACK_TIMEOUT = 2

Vort при низких значениях RTT за время RTO не успевают прийти ACK`и

Vort может, стоит ограничиить минимальное значение RTO по аналогии с тем, как сделано в SSU2 ?

Vort правда, 100мс - это, может быть много

Vort так как за один RTT может прийти 10 ACK`ов (auto ackTimeout = m_RTT/10;), то предлагаю поставить MIN_RTO = 10 * 2

Opax It seems like some websites do not work over SAM (for example, <http://identiguy.i2p/>). Why is that? Is there any known bugs related to this? I am using i2pd version 2.48.0.

Vort Opax: try i2cp.leaseSetEncType=4,0

Opax Vort: What does it do?

Vort allows for encryption type 4

Vort just try to add it to SESSION CREATE

Vort if site starts working, then problem solved

Vort if not, then something else is wrong

Opax It seems like it fixed it. Thanks. But why does that need to be added?

Vort because of compatibility reasons SAM uses old encryption until told to use newer one as well

Opax Will adding that setting made it incompatible with other websites, or should it work with all with that setting?

Vort geti2p.net/en/docs/api/samv3

Vort geti2p.net/en/docs/protocol/i2cp

Vort 4,0 means both types will be supported

Vort so all sites should work fine

Opax I see. Thanks.

Vort реализовал идею onon с расчётом минимального RTT из пачки для стримов:

Vort github.com/Vort/i2pd/commit/83f0b9c0418d6f96950dd7f2c85505b77d360b58

Vort и поправил зависание стрима при смене туннелей (надеюсь, на сей раз правильно):

Vort github.com/Vort/i2pd/commit/4f8f3a386f6d278f598d65327c789dc008dd1299

Vort (последний коммит основан на ветке с двумя предыдущими)

Vort тестировал пока что только на локалхосте, скоро буду на основном узле проверять. так что могут быть баги

Vort ещё один коммит. ждать 18 секунд - это лишнее:

Vort github.com/Vort/i2pd/commit/a703d318939a3430e0d4e5c8205379ae288524cc

orignal и что получилось?

Anonymous Vort: thanks for the above conversation.. Opax was helping me with writing e-mails to qBittorrent/libtorrent, but he seems to have the knows, time and wanted to figure it out more on his own accord, so I thank you both

Anonymous Vort: according to github.com/arvidn/libtorrent/releases your change should be in libtorrent 2.0.10.0 which I'm using.. do you think libtorrent-rastebar 2.0.10.0 is the same?

onon Я что-то не могу понять как стрим обрабатывает NACK-и.

onon if (nacked) пишет а лог и что дальше? continue;

relaybot 13apophis: Guys, xmpp.ilita is going to be relocated to freebsd "selfhost facility" in 24 hours. I will NOT backup accounts, groups, history and so on. It is up to you to reregister / create rooms / icons / etc.

orignal собери транк

Anonymous Vort: any reason why/how a SAM session would drop most traffic to <kb/s after like 10-40 minutes?

Anonymous Opax: says that it doesn't sound like qBittorrent/libtorrent issue

Anonymous And I do use the libtorrent 2.0.10.0, in which you set i2cp enctype to 4,0 (not sure how that's relevant, since qBittorrent uses SAM not i2cp as Opax seems is relevant)

Anonymous openports.pl/path/net/qbittorrent/qbittorrent

Anonymous If you want I can share with you bigger description

Anonymous Some torrents for some reason seem to continue downloading successfully for many hours

Anonymous And restarting qBittorrent makes it so torrents work again

Anonymous What do you think might be at fault here? qBittorrent? libtorrent? i2pd SAM?

Anonymous libtorrent uses SAM, does it somehow need i2cp enabled, since Opax for some reason mentioned it?

Anonymous This is all stupid, why does qBittorrent not have --log??!??!

Anonymous Perhaps Opax meant value in SAM's SESSION CREATE or something

Anonymous There seems to be a fuck-ton session-mentions in qBittorrent source, so not sure

Anonymous Opax: I think we should still send those e-mails to qBittorrent and libtorrent

Vort Anonymous: "do you think libtorrent-rastebar 2.0.10.0 is the same?" - yes, Rasterbar is just company name: rasterbar.com

Anonymous oh lol

Vort "<~orignal> и что получилось?" хз как полноценно потестировать. с чата не кидает. большинство сайтов открывается нормально. разве что заподозрил какую-то несовместимость с java, надо будет разбираться

orignal ну неплохо

Vort "<onon> Я что-то не могу понять как стрим обрабатывает NACK-и." я об этом писал вчера. никак не обрабатывает

orignal если хочешь PR сделать то сегодня

orignal завтра я уезжаю

orignal если и буду заглядывать то изредка

orignal стрим обрабатыват NACK-и путем перепосылки ))

Vort "<Anonymous> Vort: any reason why/how a SAM session would drop most traffic to <kb/s after like 10-40 minutes?" lots of streams eating all destination bandwidth maybe?

Vort "<Anonymous> What do you think might be at fault here?" most likely, i2pd. less likely, libtorrent. almost no chance qBt is related, but who knows

Anonymous Oh, so you think i2pd is broken?

Vort "<Anonymous> libtorrent uses SAM, does it somehow need i2cp enabled" SAM allows to specify i2cp options, no need to open additional port

Anonymous oh really?

Vort "<Anonymous> Perhaps Opax meant value in SAM's SESSION CREATE" yes

Anonymous so like sam......EncType = 4, 0?

Anonymous Isn't that the default in libtorrent (your commit)?

Vort my commit makes libtorrent to pass this option to SAM

Vort so no additional user intervention is needed

Anonymous so what is not working in i2pd then?

Anonymous there are more bugs than features, orignal

Anonymous :(

Vort enctype was just related to non opening websites/trackers

Anonymous so if qBittorrent uses libtorrent with that enctpye, it should work?

Vort if they respond, but work like shit, that's separate problem ))

Anonymous But it doesn't

Anonymous so it must be i2pd problem?

Vort "<~orignal> если хочешь PR сделать то сегодня" ну раз никто не нашёл проблем, то буду делать

orignal ага давай

Vort github.com/PurpleI2P/i2pd/pull/2045

Anonymous fuck github-

Anonymous Blinded message

Anonymous Vort: why don't you use I2P git community or whatever eepsite?

Anonymous I think it's Gita

Anonymous Gitea

orignal because the main repository is github

Vort не пойму почему народу больше нравится тестировать уже влитые изменения. сложно собирать из другой ветки?

Vort мне метод "влить, а потом тестировать" кажется странным

orignal просто влом

Vort но если иначе тестировщиков не набирается, то приходится так...

Vort кстати, волну атаки/перегрузки 3 часа назад никто не заметил? или уже все привыкли? :)

Anonymous orignal: can't mirror issues?

Anonymous fck

orignal я раз тут отвалился

Vort надеюсь, что проблему зависания стрима при потере пакета я починил. но теперь надо бы понять, из-за чего пакет теряется

Vort опять у меня подозрение на очень интересный баг

Vort но сегодня уже гонять не буду, наверно

Vort теряется один пакет внутри пачки. без как-либо предварительных лагов

Vort просто исчезает куда-то и всё

Vort без каких-либо*

Anonymous Vort: so what's wrong with SAM/sessions? Github can't show issues without JS

Vort Anonymous: as I said, I suspect SAM session can't handle large amount of streams

Vort can you check if such correlation exist?

Vort more streams -> less torrent speed

orignal возможно что баг

orignal там море багов

Anonymous well

Anonymous I did expect 3->16 quantity to be SUPER FAST, I'm not sure it is

Anonymous IDK, some torrents can reach 200kb/s

Anonymous or something like that

Anonymous Vort: orignal why don't you install qBittorrent? Can you not replicate the issue?

Anonymous issues* (qBittorrent doesn't continue downloading after i2pd is restarted, session is lost and it's stuck there forever, who's fault is that? i2pd's or libtorrent's?)

Vort Anonymous: I said not about tunnels, but about streams (actual connections to torrent peers inside of SAM session)

Vort I saw similar issue, but did not tracked it

Vort I saw lags during name lookups

Anonymous I don't understand

Anonymous you mean total qBittorrent speed of all tunnels (which would be == to session speed)?

Anonymous Vort: for me about 10-40 min after start almost all torrents go to 0kb/s

Anonymous or 1kb/s

Anonymous upload speed goes up down up down

Anonymous up to normal, down to 0kb, waits, then again up

Anonymous down is not s lucky

Vort open SAM session in web console and you will see Streams table

Vort and then try to understand if its size is related to download speed

Anonymous oh

Anonymous yeah

Anonymous there are streams

Anonymous I thought those were tunnels lol

Anonymous it's size?

Vort amount of streams in table

Anonymous there are like 2-4 streams even if there are 0-2 peers (inactive, 0kb/s up/down) in qBittorrent

Anonymous omg

Anonymous wait

Vort because of communication with tracker

Anonymous I got 2 peers, 1 down 1 up right now, and I have like at least 10 streams online

Anonymous oh

Anonymous 1 session and 1 acceptor

Vort this is suspicious

Vort why streams are alive if no sessions for them?

Vort probably I just forgot how it should work :)

Vort or you found yet another bug :/

Anonymous What do you mean no sessions for them?

Anonymous Session is gone if you restart i2pd

Anonymous like i2pd is running and qbittorrent is running

Anonymous you restart i2pd, qbittorrent doesn't get traffic, because old session is dead

Anonymous this is another issue

Vort then I just forgot how things are named there, sorry

Anonymous not main issue

Anonymous np

Anonymous no problem

Vort 10 streams should not create much problems I think

Vort when I was testing I saw hundreds of them

Vort and most of them empty

Anonymous problems? <10kb/s upload/down

Anonymous ok now down is 0, most streams are gone

Anonymous down was also ~10-20kb/s

Anonymous now it's probably 0kb/s forever

Anonymous Vort: do you want e-mail?

Anonymous I wrote a shitty e-mail for qbittorrent+libtorrent devs

Anonymous You maybe get more info from that

Vort maybe slow speed is just because you have only 1 peer?

Anonymous my eyes are really bad

onon Я надеюсь, вы не собираетесь это всё в релиз пускать?

Anonymous Vort: yes

Anonymous But when I connect to many many many peers, streams are also like not >20 I think

Anonymous idk

Anonymous But now there is 0 down

Vort you try to connect, but many peers may be inactive

Vort did you saw "many many" active peers?

Vort with traffic I mean (download or upload)

Vort Anonymous: I saw your mail, but I read it only partially

Anonymous oh

Anonymous want again?

Vort it's just someone needs to track/chase this problem (with low speed)

Anonymous cake.i2p/file/au8D81F7T2_8q4miMfiTvsX6w2XXjvluikbydCDsA_zDHgsxzcbh/invite-torrent-devs

Anonymous Here

Anonymous Low speeds? you mean low speed for 1 stream?

Vort I mean problem which you describe (high speed at start and low speed after 10+ min)

Anonymous low speed? no

Anonymous 0kb/s

Anonymous under 1 hour

Anonymous it goes slower

Anonymous slower

Anonymous slower speed

Anonymous slower

Anonymous slow

Anonymous very slow

Anonymous 1kb/s

Anonymous 0kb/s

Anonymous for all torrents except 1 maybe, I tried to do it 2 times, it worked for hours, maybe it's torrent-specific? I had 2 torrents that worked 100% non-stop, so this is what confused me a lot

Vort Anonymous: did you tried to test i2pd with my latest changes? I tried to make streams more robust, but no test results from users yet :(

Anonymous oh

Anonymous Well I have what's on openports.pl

Anonymous 1min

Anonymous openports.pl/path/net/i2pd

Anonymous This is what I use

Anonymous I'd have to compile it myself, with all the changes

Anonymous cvsweb.openbsd.org/cgi-bin/cvsweb/ports/net/i2pd

Vort there were many fixes since release

Vort but maybe also new bugs :)

Anonymous hmmm there are only 4 patches

Vort so testing is needed

Anonymous oh

Anonymous yeah maybe also new bugs which can deanon me lol

Anonymous I'll do testing when I buy VPS :(s

Anonymous sorry I can't sooner

Anonymous Too big anon-risk

Vort ok

Anonymous You think that those fixes fix my issue?

Anonymous Vort: is there maybe short video explaining why I2P has to have 4 protocols/whatever: BOB SAM I2CP I2Control ?

Anonymous Why not 1?

Anonymous It's a little confusing to me, I don't know differences

Vort there is slight chance of fixing and slight chance of making it worse

Anonymous maybe some acetone video about that in English or something?

Anonymous lol

Anonymous Vort: test on a VPS

Anonymous like orignal does

Anonymous get him to test it

Vort "<Anonymous> Why not 1?" because I2P is not perfect

Anonymous If I2P minimizes servicable surface (place where bugs come from), then there will be less bugs and less time to waste

Anonymous orignal: consider checking out suckless.org

Anonymous You could maybe learn something there

Vort people are already using all of these protocols, so removing them will create problems

Anonymous I don't know I2P well and I don't know differences between BOB, SAM, I2CP and I2PControl, but does everyone one of them have to exist?

Vort and also there are no single best replacement for them

orignal отъебись ))

Anonymous Vort: so what if it creates problmes? have backwards compatibility for some time and then less code = less bugs to fix

Anonymous ))

Anonymous There aren't?

Anonymous So each is required and has no replacement?

Anonymous fuck my eyes

relaybot 13apophis: yeah

Vort in distant future someone may create 5th, best, protocol. then, after 5-10 years, all other protocols won't be neeeded

Anonymous 5-10 years? nonono

Anonymous such thing needs to happen within 6 months or faster

Anonymous Less code to maintain = better

Anonymous Because now we have all this shit features

Vort Anonymous: imgs.xkcd.com/comics/standards.png

Anonymous and you and orignal can't fix them yet, maybe you will fix them in 3 months, but you waste 3 months of time maybe

Anonymous I know about it

Anonymous But it still doesn't change that shit can be universal

Anonymous I was working on a net-lib, and client and server were almost same code

Anonymous I was creating it in C, for my own game

Anonymous I made it so it's less code, same features

Anonymous it's better

Anonymous if you have 10T of RAM, you don't use 10T of RAM just because you can

Anonymous you use 1M of RAM

Anonymous example

Vort Anonymous: do you see with what speed arvidn improves SAM support in libtorrent? guess how long he will make transition to new protocol

Anonymous lol

Anonymous Same can be said for i2pd fixes

Anonymous SAM still crashes like 1 year later

Anonymous ))

Anonymous Just saying

Anonymous 100k SLOC < 60k SLOC

Anonymous example

orignal охуеть книжка скаичвается со скоростью в 3 раза больше чем обычно

Anonymous I can't wait to see how better i2pd gets in those 5-10 years, Vort

Anonymous Maybe we'll have speeds 5x faster

Anonymous maybe orignal dies tomorrow, killed by the spies

Anonymous Anyways sorry for bad words, you still do better than what I'm doing, I don't help with code at all

relaybot 13apophis: > Anonymous: maybe orignal dies tomorrow, killed by the spies

relaybot 13apophis: LOLOL

relaybot 13apophis: gosh ... you arent serious, are you ?
