| MasterDuke | ha. github.com/MoarVM/MoarVM/blob/main...up.pm#L422 | 19:03 | |
| while there's a small crowd online, any further thoughts on github.com/MoarVM/MoarVM/pull/1989 ? | 19:05 | ||
| lizmat | meh, it keeps falling through the cracks | 19:49 | |
| I'll merge it now | |||
| unless timo tells me not to in the next 15 mins :-) | 19:50 | ||
| timo | the tests in that issue look reasonable, it's probably fine. i didn't look closely at the topic in general, sorry! | ||
| Geth | MoarVM/main: 5149347a80 | MasterDuke17++ (committed using GitHub Web editor) | src/math/bigintops.c Restore smallint optimization for nqp::mod_I (#1989) Copies the implementation from rakudo. |

| MoarVM: MasterDuke17++ created pull request #2004: Check results of explicitly allocating from libc |
02:05 | ||
| MoarVM/main: f2e25d78d5 | MasterDuke17++ (committed using GitHub Web editor) | 2 files Check results of explicitly allocating from libc (#2004) Otherwise we could leak and/or dereference NULLs. |

| MoarVM: orbisai0security++ created pull request #2005: fix: the moarvm debug server accepts connections and... in debugserver.c |
08:56 | ||
| timo | something we could do for access control to the debug server socket is to require a "password" / token to be passed early on in a connection attempt which moar would write to a file umasked 077 in $TEMP so if a different user wants than the process owner wants to connect, they just have to "prove" they can read that file | 12:12 | |
| then a debug client can either try to read the file automatically and just send it, or tell the user where to find the file and ask for the contents to be copy-pasted | |||
| unix domain sockets would be possible, too. there is an equivalent on windows AFAIK but I'm not sure how it works | 12:13 | ||
| how does the java management interface or whatever it's called do it? I seem to recall you can set a host and port, probably also a password, right? potentially also TLS keys and certs and such? | 12:16 | ||
| how well would it work to have an anonymous socket as an FD that you have to pull out of /proc/$PID/fd/N? :D | 12:17 | ||
| [Coke] | seeing some buffer overflows in MoarVM/linenoise. how do we want to deal with those? | 14:05 | |
| timo | we have our own fork of linenoise? | 15:04 | |
| is it the same problem again where we don't have a proper struct definition for the standard library of your platform and that's why we write over our allocation? like we had with termios? i think that was tcgetattr and tcsetattr? | 15:05 | ||
| [Coke] | timo: github.com/MoarVM/linenoise | 16:24 | |
| but also not here: github.com/MoarVM/MoarVM/tree/main/3rdparty | 16:25 | ||
| timo | yeah, i'm not sure what we used that for, all those years ago | ||
| | * 0bff0279b - Remove linenoise/readline (11 years ago) <Rob Hoelz> | |||
| [Coke] | I'll stop scanning that repo, then. | 16:26 | |
| timo | we used to have a MVM_file_readline_interactive_fh | ||

| lizmat | do we have an easy way to see what C gives with sprintf(q/X%3bX/,0) ? | 19:06 | |
| actually: sprintf(q/X%+3bX/,0) | |||
| timo | nativecall into it? :) | 19:31 | |
| lizmat | heh... interesting idea :-) | 19:37 | |
| m: use NativeCall; sub zprintf(str $format, *@a) is native is symbol<sprintf> {*}; say zprintf("%x",42) | 19:41 | ||

| patrickb | sprintf takes three args, not two. first is the outstring | 20:24 | |
| Iirc out strings kinda suck. (maybe I misremember) | 20:25 | ||
