mareki2p Hi, I did some programming after some time, and I figured some (interesting?) router behavior (java, non-plus). When I create my new app that connects via I2CP, I can create a session. The router sends me (among request lease set) a SetDate message from time to time. Exactly 1x per 10minutes. I can also create new sub-session inside this single I2CP connection. So far so good. But then, the router will send me

mareki2p 2 SetDate messages every 10minutes. They arrive exactly at the same moment and they contain exactly the same server time. Even the SetDate is not intended to be per-session as it does not contain any session id. So, is this an oversight in server logic? Is it considered wasteful to send exactly the same message twice?

zzz sounds like a bug

dr|z3d some tweaks to the /tracker page.. I'll host the code on git.skank when I've finished. drop.i2p/paste/174186be89e54230b99129d6b4ffc8a2

dr|z3d tracker urls also lose the href, retaining the same styling, but are now click to select all. doesn't make sense having hrefs there.

orignal when should I send SetDate through I2CP?

mareki2p i2pd does not send SetDate I2CP messages just willy-nilly, it sends it upon request from client, when it asks via GetDate message, usually only at I2CP connection startup, Java router sends them whenever they want, without being asked for them, it is exactly (up to 10ms) 1x per 10minutes, it is mentioned somewhere in the docs

mareki2p geti2p.net/spec/i2cp

mareki2p 0.9.20 Additional SetDate messages may be sent to the client at any time

mareki2p Additional SetDate messages will not be sent to clients in the same JVM.

orignal i2pd doesn't send at all

orignal that's why I'm asking

mareki2p Yes, i2pd does send SetDate message, single message, at the start of I2CP communication. It does not send the server version field in that message, but it does send it.

orignal I mean periodially nit during handshake

zzz oooh you don't return your version? that's bad, it means we can't use host lookup

zzz can you fix that please orignal ?

mareki2p Do clients require that string? Do they act upon it? First time I read the docs few months ago I was a lot confused, because I was expecting separate I2CP version number from Java Router version number. So I decided to ignore that field and handle unrecognized messages when they happen.

zzz it's the API version

zzz it's not required but if it's not present we have to assume 0.8.6 or older, which is 14 years ago, no new features since then

orignal please tell me what I need to fix

mareki2p Maybe I will hit some problems with it in the future. For now I decided to re-write my software from scratch. And I have no ide how or if I even implement streaming. It is still in super very early stage.

mareki2p i2pd does not need to fix anything as nothing is broken with it

dr|z3d if i2pd doesn't send api version, that needs fixing, as zzz just indicated.

mareki2p Oh, sorry I was still thinking about the date message, I'm very tired, sorry.

mareki2p *about the periodical date messsage

zzz or maybe you don't support host lookup...

zzz orignal, go thru the version chart at the top, see what version you support, then include that version in the setdate message

zzz as specified

orignal version of what?

zzz stand by

mareki2p Also the docs say that the RequestVariableLeaseSetMessage is only for clients since 0.9.7, but i2pd does not care about any version numbers and uses that message.

zzz mareki2p, are you sure he doesnt send it? I see it in his code

mareki2p i2pd does send SetDate message, but with empty versio string

zzz mareki2p, orignal, I2CP.cpp line 633

zzz mareki2p, are you sending a version?

orignal yes, I see one

orignal so I send it back

mareki2p No, I'm sending empty string.

zzz orignal, don't echo client version. Send your API version

zzz so you both have a bug. mareki2p don't send empty string. orignal send your version, don't echo client version

orignal so I receive GetDate and send it back

zzz yes but send your API version 0.9.xx

orignal how and when should I send unsolicited?

zzz you don't need to send unsolicited. We do because we have internal clock adjustment. I don't think you do?

zzz repost

zzz so you both have a bug. mareki2p don't send empty string. orignal send your version, don't echo client version

orignal so API version is like 0.9.66 ?

zzz correct

orignal will fix

orignal thanks

zzz in "string" format, length + string

orignal e.g. pascal string

zzz :)

orignal you are old ennough to remeber pascal ))

mareki2p I have not heard that name for very long time.

zzz ofc. took it in school, probably still have a book around somewhere

orignal Pascal was a proamming langiage

mareki2p I remember I added mousewheel support for some grid view window control in Delphi7. This was my first paid job/internship during shool.

zzz we used to do like 6 languages in one semester. Lisp, SNOBOL, Forth, ...

zzz anyway, re: dup setdate messages to subsessions, thanks for the report, I have it fixed, just need to test before checking in

orignal you know Pascal was popular in ex-USSR until mid of 90s

orignal because lack of hardware

orignal 286 was good for Pascal and not for C++ ))

zzz look at mareki2p finding two bugs in one day, one on each router, not playing favorites, good job ))

mareki2p I heard stories from some company that when they transitioned their software from Pascal to C and later to C++ that it started crashing much more. Skill issue on the engineers I guess.

mareki2p Thank you. (-: it makes me happier.

mareki2p I have more quiestions zzz, when reading the docs, it mentions the sub-sessions in single I2CP connections. But, there is limitation that the other sessions need to use the same encryption keys as the master sessions and that it is detectable that two destinations are related in this way. Why is that? I guess left-over from the past. So if I want to create uber-anonymous bittorrent client over I2CP and I want t

mareki2p o have unique destination per torrent, then I can not use sub-sessions, but I need to establish new I2CP connection to the router. Correct?

zzz correct

zzz because subsessions use same tunnels, so must be same encryption

mareki2p Any plans to improve this?

zzz no

zzz you want multiple tunnels, use multiple I2CP connections

orignal zzz, look right now?

orignal *loks

orignal *looks

orignal sorry one more mistake

orignal done

zzz sure, even fixed the spelling in the comment ))

orignal lol

zzz but I'll leave it to mareki2p to test it...

mareki2p That +1 and +8 should not be magic numbers. They should be named constants. Something like message_type_len=1 message_size_len=4 message_header_len=message_type_len+message_size_len set_date_date_len=4 set_date_string_size_len=1 and so on.

orignal let me try with snark

orignal it's obsious in this context

orignal what is 8 and what is

orignal 1

mareki2p I saw +8 and I was thinking ... the date is 32bit not 64bit, right?

zzz 8 bytes

orignal it's just memory reservation for reposnse

orignal timestamp is 8 bytes - 64 bits

mareki2p Oh, I was thinking 1 byte for message type, 4 bytes for message lenght, 4 bytes for timestamp, 1 byte for string length.

snowflakes Я АНОНИМНЫЙ ПИДОРАС

snowflakes НАРОМАН ТО ЕСТЬ

snowflakes hello guys whats happened there

snowflakes i kidding if true

snowflakes My appologize for my joke

zzz fixing bugs, what's up with you?

snowflakes Maybe write some documentation about i2cp with examples of code?

zzz sounds like fun!

snowflakes why fun

snowflakes I love kotlin but

snowflakes fun lol

snowflakes i dont use i2cp even I use i2p more than 8 years

snowflakes oh not, i used that like when used snark for torrents

snowflakes so all that I used

snowflakes its for torrenting

snowflakes zzz, I’ve been having some trouble with real-life issues and some health/diagnosis stuff lately. But I won’t bring it here, since I know this channel is for more useful and technical things. Still, thank you for asking

mareki2p OK, tested i2pd. It reports back version 0.9.66 even if I send it something different, such as 0.9.65.

zzz snowflakes, best wishes for things getting better ))

mareki2p I also vaguely remember that i2pd does not care about authentication in the I2CP protocol. But I do not have the enerty today to test it out.

orignal working with snark

orignal zzz, plaz has mental disorder again ))

orignal mareki2p what king of authentication are you talking about?

orignal I didn't know it even exist
