00:43:42termerElegantbeef Talking shit about me once again
00:44:05termerHow do the likely/unlikely hints generate worse code
00:44:16termerwhen I use them, I know that those things are more or less likely
00:48:12FromDiscord<Elegantbeef> Hey I was mostly jesting about the throwing them in 😄
00:48:33FromDiscord<Elegantbeef> But likely and unlikely need to be on the branch that is known to be slowed down by the predictor
00:52:05FromDiscord<Elegantbeef> So it might not actually slow down code and I might've been silly, but throwing likely around without benchmarking is just pollution!

04:53:25termerthe info may also be available in the stdlib winlean module
04:53:48termermake sure you add `when defined(windows):` to make your windows code conditional, unless your program only runs on Windows to begin with
04:55:48arkanoidwhat are the right switches to statically compile libssl ?
04:56:26arkanoidI'm trying with dynlibOverride ssl but it complains "Error: undeclared identifier: 'newContext'"
04:57:31arkanoidit compiles with switch("d","ssl"), it doesnt with switch("dynlibOverride", "ssl"). If I enable both, it seems to ignore switch("dynlibOverride", "ssl")
04:59:24FromDiscord<␀ Array 🇵🇸 🍉> which distro are u using inside the vm/lxc? you can use your package manager to install nim. otherwise the choosenim script can be used on all distros
05:04:39FromDiscord<Elegantbeef> Arkanoid `nim c -r -d:ssl --dynlibOverride:"ssl" --passL:$(pkg-config --static --libs libssl) ./test.nim` works here
05:05:05arkanoidElegantbeef, are you using std/net newContext in your test?
05:05:11FromDiscord<Elegantbeef> Yes
05:05:35FromDiscord<Elegantbeef> `import std/net; var a = newContext()` is my entire code
05:06:30FromDiscord<Elegantbeef> No one asked, but pkg-config is amazing 😄
05:06:49arkanoidsure, it is
05:09:39FromDiscord<ipumpbuh4> I use proxmox
05:10:17FromDiscord<Elegantbeef> Though arkanoid I don't know if the above properly statically linked it
05:10:50FromDiscord<Elegantbeef> The procs are there but so is `dlopen` and `dlsym`
05:11:10arkanoidElegantbeef, it's not: error while loading shared libraries: libssl.so.3: cannot open shared object file: No such file or directory
05:11:37arkanoidI feel -ssl is not compatible with dynlibOverride
05:11:40arkanoidfor some reason
05:11:47FromDiscord<Elegantbeef> It has to be
05:12:01FromDiscord<Elegantbeef> dynlib override is a compiler feature `ssl` is in userspace
05:12:25FromDiscord<Elegantbeef> The stdlib uses the dynlib pragma not std/dynlib
05:13:35arkanoidI've tried your compilation line, but I was using this config.nims originally https://termbin.com/fsqz
05:14:19FromDiscord<Elegantbeef> Got an easy way to test this? Don't know how aside from writing a program that uses seccomp 😄
05:15:19FromDiscord<Elegantbeef> https://github.com/nim-lang/Nim/blob/version-2-0/lib/wrappers/openssl.nim#L283 yea there is even a static link check
05:15:46FromDiscord<Elegantbeef> Oh I was wrong they do use dynlib in this module

05:21:27FromDiscord<Elegantbeef> Now just use pkg-config for style points 😛
05:21:32FromDiscord<Elegantbeef> I joked cause apparently it does not remove duplicates
05:21:48FromDiscord<Elegantbeef> `pkg-config --static --libs libssl libcrypto` emits `-lssl -lcrypto -ldl -pthread -lcrypto -ldl -pthread`
05:23:37arkanoidwhat is missing with pkg-info is --static
05:24:16arkanoidnim wants --passL:"-static" but "pkg-config --static ..." strips it
05:31:36*def- quit (Quit: -)
05:38:48arkanoidI confirm that it does work
05:39:04arkanoidbut I wonder why pkg-config is ignoring --static
05:39:39FromDiscord<Elegantbeef> I don't think it is
05:40:03FromDiscord<Elegantbeef> I just think it expects you to do `-static $(pkg-config --static --libs libssl libcrypto)`

19:20:04FromDiscord<leorize> i mean you can ask \:p
19:24:31FromDiscord<Robyn [She/Her]> I can! But I don't understand any of httpleast's code lmao
19:24:51FromDiscord<Robyn [She/Her]> I think I'm gonna try implementing a HTTP server using nim-sys and cps, and just see how it goes
19:25:17FromDiscord<leorize> for starters you can look at httpleast.nim and only that file
19:25:28FromDiscord<leorize> focus only on the stuff that said `leastQueue == "nim-sys"`
19:26:05FromDiscord<Robyn [She/Her]> Alright!
19:29:03FromDiscord<Robyn [She/Her]> Does httpleast only support posix OSes?
19:30:00FromDiscord<Robyn [She/Her]> And does posix include Windows?-
19:30:24FromDiscord<Robyn [She/Her]> It's in this weird state of being semi posix-compliant, I think?
19:31:41FromDiscord<griffith1deadly> nim-sys support windows as i knot
19:31:46FromDiscord<griffith1deadly> (edit) "knot" => "know"

21:19:28FromDiscord<Robyn [She/Her]> Thanks for the tip!
21:30:07FromDiscord<djazz> playing with closure callbacks, passing ref to C library. `SIGSEGV: Illegal storage access. (Attempt to read from nil?)` thank you nim very helpful error
21:30:32FromDiscord<Elegantbeef> I feel like that's hard to improve on
21:30:44FromDiscord<djazz> probably because generic kind on type
21:30:46FromDiscord<Elegantbeef> As soon as you leave the confines of Nim it's down to the library 😄
21:30:51FromDiscord<Robyn [She/Her]> Seems that the reference was freed before it was accessed, seems like a pretty useful error :P
21:31:04FromDiscord<Elegantbeef> Unless that's a compiler error
21:31:04FromDiscord<djazz> this is when compiling nim ,not runtime

21:31:41FromDiscord<djazz> i got further with GC_ref()
21:31:55FromDiscord<Elegantbeef> It's a nil ref error due to some funkyness

21:33:03FromDiscord<Elegantbeef> Ah the one in std/net
21:33:05FromDiscord<djazz> an enum
21:33:07FromDiscord<djazz> no
21:33:14FromDiscord<djazz> this is custom
21:33:25FromDiscord<Elegantbeef> `SocketAny` is what `Socket`?
21:33:36FromDiscord<djazz> `SocketAny = ref Socket[SOCK_STREAM] | ref Socket[SOCK_DGRAM] | ref Socket[SOCK_RAW]`
21:33:46FromDiscord<Elegantbeef> Ugh
21:33:57FromDiscord<Elegantbeef> Are those the three instances of sockets?
21:34:01FromDiscord<Elegantbeef> Or are there more enums
21:34:20FromDiscord<djazz> SocketType is an enum
21:34:34FromDiscord<Elegantbeef> I know
21:34:41FromDiscord<djazz> sent a code paste, see https://play.nim-lang.org/#pasty=SCMJPekjHGcw
21:34:50FromDiscord<Elegantbeef> But do you only have 3 values for the enum?
21:34:55FromDiscord<djazz> yeah
21:35:13FromDiscord<Elegantbeef> well `ref Socket` is the same as that
21:35:35FromDiscord<Elegantbeef> Using generics without parameters is an implicit typeclass
21:35:48NimEventerNew thread by arnetheduck: [arnetheduck] `nph` opinionated formatter v0.5, see https://forum.nim-lang.org/t/11093
21:37:32FromDiscord<Elegantbeef> I do wonder how that typeclass is parsed it might be parsed as `ref (Socket[X] | ref (Socket[Y] or ref Socket[Z]))`
21:38:09FromDiscord<Elegantbeef> Whether that's causing the error is another thing 😄
21:40:13FromDiscord<djazz> sent a code paste, see https://play.nim-lang.org/#pasty=hKUahyUupHsL
21:40:26FromDiscord<djazz> last line in that code
21:41:14FromDiscord<djazz> if i remove [kind] i still get nil
21:41:26FromDiscord<djazz> so i need SocketAny combined type
21:41:28FromDiscord<Elegantbeef> In that cause you probably want `ref distinct Socket` 😄
21:41:42FromDiscord<Elegantbeef> Typeclasses are bound to the same symbol inside a proc without that `distinct`
21:42:17FromDiscord<Elegantbeef> Do you use that enum for anything else?

21:43:25FromDiscord<djazz> and callbacks for specific socket types
21:43:37FromDiscord<djazz> connect function for udp : `proc connect(self: ref Socket[SOCK_DGRAM]; ipaddr: IpAddrT; port: Port): bool =`
21:43:55FromDiscord<djazz> this worked great with var and without callbacks (:
21:44:02FromDiscord<Elegantbeef> Right that'd just be `ref Socket[UdpPcb]` 😄
21:44:18FromDiscord<djazz> Right
21:44:24FromDiscord<Elegantbeef> Wait a minute callbacks are these generic callbacks that expect a socket type?
21:44:39FromDiscord<djazz> yeah
21:44:47FromDiscord<Elegantbeef> Are you just forgeting to take in a `[Kind: static SocketType]` inside your callbacks?
21:44:54*xet7 joined #nim
21:46:10FromDiscord<Elegantbeef> Atleast I assume the socket callback is presently `proc(_: ref Socket, ...): ...`
21:46:32FromDiscord<Elegantbeef> Whereas it needs to be `proc[Kind: static socketType(_: ref Socket[Kind], ...): ....`
21:46:37FromDiscord<djazz> this generic function has a inner closure that then calls a callback, depending on the kind
21:46:54FromDiscord<Elegantbeef> So it's type erased?
21:46:59FromDiscord<djazz> probably
21:48:57FromDiscord<Elegantbeef> How much code is there?
21:49:09FromDiscord<Elegantbeef> Would I be daft to ask to see the entire code?

22:44:54FromDiscord<Elegantbeef> Possibly worth noting I don't think you need the `dnsGetHostByNameCb`
22:45:09FromDiscord<Elegantbeef> you should be able to do `callBack.rawProc` and `callBack.rawEnv`
22:46:09FromDiscord<Elegantbeef> If `getHostByName` is empty does the code still explode?
22:47:08FromDiscord<djazz> i saw some about rawProc/rawEnv but found no examples
22:47:35FromDiscord<Elegantbeef> `rawProc` should be `proc(..., env: pointer)`
22:48:13FromDiscord<Elegantbeef> https://nim-lang.org/docs/intern.html#code-generation-for-closures
22:49:35FromDiscord<Elegantbeef> As such it's interoperable with your code assuming you do `cstring, ptr IpAddrT, arg: pointer`
22:49:55FromDiscord<Elegantbeef> Though you can actually do `arg: DnsCbState`
22:50:01FromDiscord<Elegantbeef> Wait that's wrong
22:50:31FromDiscord<Elegantbeef> Anyway I don't see anything that stands out as explosively bad
22:54:37FromDiscord<djazz> hmm
22:55:20FromDiscord<djazz> atleast i got it running async now
22:55:47FromDiscord<djazz> the tls stuff still freezes everything, since its not actually multithreaded
22:55:58FromDiscord<djazz> its interrupt driven
22:56:30FromDiscord<djazz> so https makes it freeze on connect for 3 secs, then its smooth and led is blinking while doing the fetching
22:56:45FromDiscord<djazz> the blocking io bothered me haha
22:57:44FromDiscord<djazz> from pico sdk docs `async_context_threadsafe_background provides an implementation of async_context that handles asynchronous work in a low priority IRQ, and there is no need for the user to poll for work.`
