AuroraOS

[quaint cape]

Init subsystem coming in clutch.

[ashen plume]

yeah i think mine is pretty cool

[quaint cape]

I just stole Mathewnds

[quaint cape]

That is shorter than mine.

[ashen plume]

each of my stages calls some functions

[spiral field]

huh, this doesnt even need a loop

[ashen plume]

How’s that

[mental otter]

void init() {
  step1();
  step2();
  step3();
  step4();
}

[oak charm]

Yeah

[ionic palm]

Mine is an absolute bloat

https://github.com/VOXIDEVOSTRO/AxeialOS/blob/main/Kernel/Entry.c

[quaint cape]

Well personally (no offense) I have a hard time understanding anything in your OS, that's not cuz it's bad just that its different and doesn't follow most OS's structure. It's also C++ which just adds to the confusion.

For me its just a blob of folders that mean nothing.

[ionic palm]

Indeed, but that's probably because of the weird coding style

[quaint cape]

And the lack of subfolders.

You don't categorise anything.

[ionic palm]

-# because obviously i'm stupid

[ionic palm]

i don't it's only one level deep

tho i promise my #1467786251510743061 would be WAY WAY cleaner then this

[mental otter]

I program in C but I use clang to give me function overloading

[quaint cape]

Yea, well exactly.

Personally I'm pretty happy with how the AuroraOS source has turned out.

[mental otter]

I like how mine is but I still need to cleanup a lot of it

[ionic palm]

yea it's clean, well i didn't clean up my CSource tree for AxeialOS since when i first started its dev

[quaint cape]

Yours is pretty good yea

[mental otter]

Once I get bash posted and then a few rewrites of a few systems and it should be perfect for a beta1 release

This code is pretty

@quaint cape Whatcha working on rn

[quaint cape]

I'm in school.

[mental otter]

Ahh

I mean like in general on the kernel

Sorry

[quaint cape]

No worries, social studies are boring asf anyways.

[quaint cape]

Fixing the remainder of bugs in my new scheduler.

Which have per-cpu runqueues.

And much more arch abstraction.

Fixed the main one yesterday.

it was my TSS being f'ed.

I'm also going to make a better paging impl.

[mental otter]

Oh nice nice

Whatcha gonna do for paging

[quaint cape]

I'm to afraid to touch my paging.

[mental otter]

I mean x86-64 paging is pretty basic

Just some layered tables

Think of it like fixed sized radix trees

[quaint cape]

I have paging.

I'm to afraid to change it.

[mental otter]

https://tenor.com/view/spongebob-angel-gif-4351457

You can steal mine

It’s getting finished tomorrow

With VMA too

My paging is done except unmap and TLB shootdowns

I’m also gonna add support for 1GB and 2mb pages too

[quaint cape]

Cool.

I don't really have any VMA.

I'm to scared to change my paging for now.

Last time I did i f'ed up the whole OS for multiple months.

[mental otter]

My VMA is also open source well will be once I finish it lmao

[mental otter]

This is part of my VMA actually

[mental otter]

Let me see your paging right now

It can’t be that bad

I also managed my pacing rework in a day worked perfectly

[mental otter]

Your gonna need one for MMAP later

[quaint cape]

Trying to fix more bugs

Also fixed panic so it's a bit better now.

[quaint cape]

Fixed all userspace-entry related bugs this morning.

Now my new syscall handler tweaks.

[quaint cape]

(had mixed up phys and virt in my paging permiters also used different constants in different files.

[quaint cape]

Added "extern asm" to snow

[quaint cape]

having fun commenting my own code

ima try to make snow semi readable unlike my other projects.

i'll commit snow in a week or two.

ima have to test everything before releasing it.

And fixing my messy backends.

and my semantic also needs to be reworked.

[quaint cape]

First syscall after rewrite done

and yes this is me trying to do something with mlibc

time to see what is messed up with archctl

[quaint cape]

Fixed logging spam atleast

And studied for tests ig.

[quaint cape]

Fixed most errors :D

though I get invalid opcode when running any mlibc related code.

[mental otter]

Do you have SSE/FPU stuff enabled?

Wait after the systemcall?

What’s the instructions at all the RIPs

[quaint cape]

nope ima fix that

found out 1 min ago before this message

[mental otter]

Yup by default mlibc will use the FPU

So make sure you save and restore the state

[mental otter]

And make sure you context switch the fsbase which seems to be what this archctl is doing?

[quaint cape]

Fixed most issues now i have to make a proper mmap impl

[quaint cape]

Hmm might have to try and build and run bash after this.

[mental otter]

mlibc does not need a full MMAP. It just needs annon pages

But it shouldn’t be too hard to support mapping tmpFS pages if you keep track of them

[quaint cape]

20k loc now'

[quaint cape]

ironing out the last bugs.

[quaint cape]

-1 bug

+1 syscall

[quaint cape]

Rewriting print logic to use a ringbuffer.

[quaint cape]

Fixed some more snow bugs

Also made borrowing

And better semantics.

And some sort of half decent runtime support.

[quaint cape]

ima be gone for a week sking

wish me lucjk

[hard trellis]

...so am I

[quaint cape]

ima have to fix issues in my sysfs now.

[quaint cape]

Stuff until bash:

• Fix sysfs.
• Fix exit syscall.
• DEbug a bit more.

It's bascially only sysfs left

and i need to actuallly run bash too.

[spiral field]

sysfs? not needed for bash

[quaint cape]

Need some way to print stuff???

I don't have a devfs

[spiral field]

why over sysfs

idk I simply added a debug log syscall when I first ported mlibc

[quaint cape]

I guess you could do so yes

[quaint cape]

ima try and fix this sysfs tmrw

[quaint cape]

Still no progress on sysfs :(

[quaint cape]

Fixed sysfs now it works

my exit implementation is broken smh

so yeee no bash for a while

[quaint cape]

get out of memory error smh

even though i run it at like 10gb RAM

ill have to investigate once i get back from todays skiing

[silk valve]

skiing? fancy

[quaint cape]

it surely is

[silk valve]

very cool , good luck with the os btw

[quaint cape]

thanks

you have any idea why puts outputs a lot of C++ code??

[silk valve]

im genuinely have no idea how is panic is in C but theres std::span

do you use c++?

[quaint cape]

mlibc does.

[silk valve]

even then iy should not be possible

[quaint cape]

I dont.

[quaint cape]

might need to ping someone who knows mlibc internals

[ionic palm]

Also @quaint cape i realized that #1467786251510743061 has the same amount of stars as #1384888317597974600 lol

[quaint cape]

cuz i have no idea.

[silk valve]

could be malformed macro?

since thats is raw c++ source

[quaint cape]

well this is a worse OS that is kind of dead tbh

[quaint cape]

could be, not probable though.

[silk valve]

yeah, i mean if you didnt touch them it shouldnt break on its own

[quaint cape]

like why would only me get it when theres like 10 OS's which use mlibc

[ionic palm]

It's decent imo, i don't care about feature sets and code quality if the code is legit

and also you can run bash is already impressive

[quaint cape]

well feature wise auroraos might have the edge.

not in portability though.

[quaint cape]

i got it running before the rewrite for like 3 mins

then i decided ima rewrite everything

[ionic palm]

How many rewrites have you done

[quaint cape]

fighting back there now-

[quaint cape]

ehh lemme count

1

2

??

2 maybe

[ionic palm]

Nice, AxeialOS was rewritten only once and Modularus none

So still it's a decent and valid number of rewrites

[quaint cape]

time to fix exit impl and then get bash running once again.

[quaint cape]

struggling to build bash smh

[quaint cape]

time to rebuild my toolchain yeaaaaaaa

[quaint cape]

running into errors when building bash

[quaint cape]

finally was able to build bash

[quaint cape]

Tmrw I'll try and figure out why bash PF's upon entry.

Probably cuz I haven't implemented something.

[ashen plume]

Seems like you’re accessing garbage memory

Make sure your mmap() call is legit

[quaint cape]

Yea, well I'll take a look tmrw

I'm too tired for this shit today.

[mental otter]

Does MMAP garuntee zeroed out memory?

[ashen plume]

No

[mental otter]

I’m like 99% sure it should

Atleast mlibc wants it to be

[ashen plume]

No. There’s a flag for it

[mental otter]

Ahh mlibc requesting anonymous pages requires zeroed pages though still

So if that’s not setup right

I’m not surprised at all page fault

[ashen plume]

I’m driving right now so im using voice to talk I’ll answer after

[ashen plume]

Yes anonymous pages should be guaranteed zeroed

[mental otter]

I meant annon pages

I forgot to say that sorry

[ashen plume]

Yeah in the unix standard MAP_ANONYMOUS for mmap would give zeroed pages

[mental otter]

Which if @quaint cape Isn’t doing i presume that’s fucking up bash badly

[ashen plume]

I don’t even bother with porting anything

Even though my process api and syscall api is Unix compat

I don’t have a proper libc

[mental otter]

You don’t even have one for your own apps?

[ashen plume]

No I have one for my own apps

But it’s in no way a full libc

[quaint cape]

Damn now my laptop panicked

Linux why 😭

I've actually never had a Linux panic .

What the f now it doesn't work

Welp f me I haven't commited my progress in so long.

[silk valve]

just updated?

[silk valve]

there is nothing wrong with this

linux cant load initrd

[quaint cape]

Negative. Hard crash

[silk valve]

live?

[quaint cape]

Prob due to not being able to clear up disk.

[silk valve]

did you touch anything recently

[quaint cape]

I'm running recovery mode to see if it fixes it.

[quaint cape]

Nope.

Okay, running older Linux version fixed it.

[silk valve]

hmm

and which distro?

[quaint cape]

Zorin.

Ig I just gotta boot into grub each time I boot?

[silk valve]

i think you can set default entry

[silk valve]

you always?

just not the menu to configure?

[silk valve]

didnt expect that

[quaint cape]

🙏

[silk valve]

my first ever distro was zorin when i was 9 10 i think, but i have skill issue back then and cant install it

it was still tui back then

[quaint cape]

🙏

[silk valve]

i didnt understand shit

i just press next

[quaint cape]

Its probably one of the most advanced ones nowadays.

[silk valve]

zorin is clean ngl

prob better than mint

mint is overrated imo

[quaint cape]

ehh its a laptop i can just never shut it off

[quaint cape]

yep

[silk valve]

ig thats a smart way

[quaint cape]

pushed everything to codeberg atleast

so i dont lose anything

[silk valve]

also, just asking

why codeberg

just because it doesnt have microsoft?

[quaint cape]

It's open-source.
It uses german servers.
It doesn't have microsoft.

[silk valve]

over performance? and infinite infra money?

well its just ones taste really

personally a more practical person

i just use whatever works best

never really consider those

[quaint cape]

What does gh have that codeberg doesn't have?

[silk valve]

performance

darker dark theme

[quaint cape]

huh?????

[silk valve]

codeberg is slow asf

[quaint cape]

Slow????

[silk valve]

the gui, git servers

[silk valve]

yes

compared to github

[midnight rampart]

its a nonsensical take, I wouldnt bother arguing the point

[quaint cape]

Yea.

[silk valve]

so in your opinion, codeberg is faster?

[midnight rampart]

faster at what?

its fast enough for everything I use it for

[silk valve]

git remote, and gui interface

[midnight rampart]

also GH stutters and now has bugs lmao

[silk valve]

never seen one yet

[quaint cape]

ohh wow, I save a few milliseconds by using gh. woooowwwww

[silk valve]

?

[quaint cape]

impressive.

[quaint cape]

those milliseconds really matter for you?

[silk valve]

what are you talking about

[quaint cape]

Codeberg being "slower" than gh.

[silk valve]

not milisecond

gui rendering is notably slower

[quaint cape]

Yes, thats what we're talking about.

[silk valve]

on slower devices

[midnight rampart]

it is your choice to provide your code and user stats to microsoft by using github, but you will be judged for it. There are good reasons people are moving away from it.

[quaint cape]

Negative.

[silk valve]

beside its oss, what is the actual reason

[midnight rampart]

reason(s)

[silk valve]

ok, reasons

[quaint cape]

Big difference right?

[silk valve]

its yours machine, not mine, and specifically, im talking about code search performance and file indexing

codeberg is much slower here

[quaint cape]

"slow"

[quaint cape]

.

[midnight rampart]

you're supporting microsoft and allowing your code to be scraped for AI usage (you'll note codeberg protects against this), codeberg is also not used as a marketing platform. This may or may not bother you, but github being a US company is a concern for many. I'm also fairly certain codeberg is a not for profit, which again is a personal choice but its a nice thing to support.

[silk valve]

hmm

[midnight rampart]

for the sake of transparency here I use both (for now), but I wont be hosting any new projects on github and generally try to avoid the github site whenever possible.

[silk valve]

i can try to mirror

like currently have a gitlab mirror

[midnight rampart]

yeah I currently have codeberg as my main mirror and it automatically pushes to the github repo for me 🙂

it has built in support for that 😉

[silk valve]

really?

[midnight rampart]

wrt to the performance, not sure what thats about - I've always found codeberg faster for everything. The exception being when its offline, which is something I've never personally encountered but people here have complained about it a few times. If you're looking at more than a file for a project imo its nicer to clone it and have the full feature set of your favourite editor to jump around.

[midnight rampart]

you're looking for "Mirror Settings" in the project settings. You could alsod do it via an action script I guess (codeberg has its own CI called woodpecker and also supports the forjego one - it has free runners for both).

[quaint cape]

quick question, do you know if bash requires dynamic linking or if its possible to only have static linking

[mental otter]

@quaint cape Did you see the thing about annon pages? Btw mlibc does give you really easy dynamic linking if you need it. And you can use the “ldd” tool to check if it’s a static binary

[quaint cape]

does it

how

[quaint cape]

also the binary doesnt even run as it requires

[mental otter]

Do anon pages give out zeroed pages

[mental otter]

I don’t think that’s compiling right?

If it’s asking for ld Linux

[quaint cape]

i think so yea

[quaint cape]

smh

this is my config

malloc*

[mental otter]

Huh

[quaint cape]

Do you have dynamic linking?

[mental otter]

I do not and I’m burnt out heavily and stuff

I’m taking a break from OSdev and I’m gonna hopefully return to the prism thing I got organized and stuff

[quaint cape]

isnt prism just a dist around ur kernel

[midnight rampart]

Ive always done a custom userspace so I don't know much about porting bash :p (this is changing with my current iteration) . What's the specific issue?

Also you'll get more eyes on your issue if you ask in an on-topic channel rather than a progress thread. I would suggest going there.

[quaint cape]

.

[midnight rampart]

This isn't directed at you in particular but its something I've noticed lately, that people are asking for help in their project threads and not the channels. The on-topic channels are there to ask for help if you need it!

[mental otter]

Nope

[quaint cape]

What is it

[mental otter]

A new kernel in C++

Due to severe corruption issues

[mental otter]

I fixed the corruption issues

@quaint cape How’s bash coming along

[quaint cape]

Making dynamic alloc for mlibc rn

[mental otter]

Sometimes it happens to me while I’m debugging it and I’m sort of rubber ducking to my channel/void and it helps and then people walk in so times with advice

[mental otter]

Nice nice

[quaint cape]

think i got dynamic linking working

huh

interesting

[midnight rampart]

thats understandable! I was talking about the case where people start by asking a question 🙂

[quaint cape]

sorry lol

[midnight rampart]

nah you're fine lol, it was just an observation

[quaint cape]

more shared library stuff yeaaaaaaaaaaaaaaaaaaaaaaaa

[quaint cape]

huh

i like how sometimes my idle thread starts and sometimes it just dies directly

[ashen plume]

I’ve been asking in my proj channel a lot yeah

[quaint cape]

continuing with bash port today

[quaint cape]

even more bash progress

imlementing all syscalls bash is complaining about

[mental otter]

Can I ask what syscalls it was complaining about?

[quaint cape]

mprotect

[mental otter]

i wonder if that can be stubbed for bash?

[quaint cape]

next one is sys_getuid

ill be here the whole evening doing these

[quaint cape]

maybe?

i just implement them all

that are easy

wait cant i just return 0 for sys_getuid since theres only one user?

@mental otter do you know if i can just return 0 for getuid and getgid?

whats the difference between getuid and geteuid

[mental otter]

you should be able to

[mental otter]

nothing afaik

[quaint cape]

and then theres getegid??

😭

[mild shoal]

man 7 credentials

should give you a quick rundown of all that stuff

[quaint cape]

sure lol

[quaint cape]

btw does bash need sys_clock_get?

or can i just stub that with return 0 since its not needed

[mild shoal]

I got into a bash prompt with these:

extern syscall_print
extern syscall_mmap
extern syscall_openat
extern syscall_read
extern syscall_seek
extern syscall_close
extern syscall_archctl
extern syscall_write

but to get a proper working shell u'll need a bit more

[quaint cape]

i have a hard time believing that sys_clock_get could possibly be needed

[mild shoal]

for bash its not

[quaint cape]

do yk if mlibc freaks out if i return ENOSYS

should i just return 0 instead?

[mental otter]

No fork

[quaint cape]

it surely cant be more funcs to stub than this

ima finish tmrw

[spiral field]

i just noticed that I didnt implement my time stubs yet, but a simple ticks++ is enough for getting started and getting bash and basically a bunch of stuff to run

[quaint cape]

do i even need signals?

cuz when i try and stub them mlibc just panics cuz it wants a real signal

[mild shoal]

No

[quaint cape]

.

[mild shoal]

When I ported it, it really didnt need signals

But that was also like 3 years ago

Worst case you success stub it

Or just patch out that ensure in your local patches or w/e

[quaint cape]

or spend a week writing an ipc implementation

[quaint cape]

well, im starting to consider maybe writing my own window compositor and porting x11

both as alternatives

since i can use sdl for the window compisitor

and then bash as the ground up shell

huh well need bash ported anyways

[quaint cape]

Implementing a lot more syscalls

Syscall count = 35 now

[rough junco]

imo the worst part of porting bash (initially) is pselect

[chrome cosmos]

posix select? i remember a time few if any os's fully implemented it because it was supposed to wait for so many different things. that was several standards versions ago, though

[rough junco]

Bash versions?

[chrome cosmos]

posix versions. it was 20 years ago i think

[rough junco]

Ahh, well yeah. It's honestly not too bad. I don't have signals yet so I just implement pselect with select which itself is implemented by poll

[quaint cape]

ehh RIP

i have 50 syscalls

[rough junco]

For bash?

Or did you move on for a bit?

[quaint cape]

got carried away

[rough junco]

lmao

[quaint cape]

just done syscalls for everything i have

and i made some sort of experimental ipc implementation

[rough junco]

What syscall does bash currently give up on?

[quaint cape]

(only signals, pipes, message queus)

[quaint cape]

dunno ima rebuild it with my new ipc implementation

ima also have to spend half an hour writing mlibc implementations for all of them

[rough junco]

How does the "experimental ipc implementation" work lol?

[quaint cape]

well it always takes 1 rewrite for me to be happy with any of my implementations

so before my next rewrite ill class this ipc implementation as shit

[rough junco]

lmao

[chrome cosmos]

that's honest! 😄 i wonder how my first implementations are going to look 😕

[mental otter]

For my non POSIX IPC that il use for my own tools I’m thinking of shared pages + a few syscalls to wait and signal

[quaint cape]

welp this might take a few days for me to patch all syscalls

i also forgot about .bashsrc and everything else i need setup

[quaint cape]

or well make all syscalls needed

i already got 50 total syscalls btw

[quaint cape]

55

huh why does it immideatly exit?

@mild shoal do i need to define those constants for it to run?

progress

[mild shoal]

No

[quaint cape]

trying to fix bugs just made it worse

[quaint cape]

input is broken though

[rough junco]

Did you end up implementing polling?

[mental otter]

Why polling? I’m pretty sure they have a keyboard driver. They just need the charater device to be opened right on bash so it can read characters from the terminal like how it’s outputting things

[rough junco]

I worded that badly. I meant a polling system i.e. i/o multiplexing

(poll, select and their signal safe variants)

[mental otter]

Ahhh

I think they have thoes?

Iirc I looked up and they were mentioning it

[quaint cape]

nope

[rough junco]

Then how did you satisfy the pselect mlibc sysdep if you don't mind me asking?

[quaint cape]

I dont.

[rough junco]

Interesting, then how do you get to the prompt? Are you doing bash with or without readline?

[quaint cape]

without readline

[rough junco]

Ahh then that makes sense

[quaint cape]

well a bit buggy but works

next i gotta debug why it throws out of memory

found it

my paging_copy impl was broken

before i commit ima have to commit quite a bit

[astral tartan]

what is paging_copy copying here? the page tables?

[quaint cape]

well before for some reason i blew my whole pmm implementation by erasing kernel bindings

now it just copies the user PML4s-

[quaint cape]

dont ask about my code its crazy bad

[astral tartan]

I know my page table copying code would probably have hundreds of bugs and race conditions so I just don't copy anything. except the mmap() areas.

and lazily populate/CoW and faults.. I tried copying on an older OS, I got random memory corruption and kernel panics all the time..

[quaint cape]

well im struggling

the thing is that as i said i mark everything as shit before being rewritten atleast once

when i get whole bash working ill rewrite the syscall logic and the proc logic

and some pagin g

[astral tartan]

just rewrite it until it works.. I'm at OS attempt 5 right now

[quaint cape]

lol well for me a rewrite is just rewriting files

i never change os

[astral tartan]

well, none of them were something serious, basically just testing grounds for allocators, paging, fork, ...

[quaint cape]

sounds good

you learn smth each time

[astral tartan]

yes, I learned not to do ACPI the next time..

[spiral field]

why?

[quaint cape]

doing acpi with uacpi rn

[quaint cape]

Hmm anyways guys should I use meson or stick with Make?

Which is better?

I wanna settle with one before my build scripts get too outta hand.

[quaint cape]

why does uacpi require fflush?

[quaint cape]

going good with uacpi 🙏 (not)

[astral tartan]

#GP in uACPI?

[silk valve]

4.0 already? didnt know that

[silk valve]

personally uses cmake

meson didnt play nice with me

and makefiles just left my source tree garbled up with objects files

[chrome cosmos]

gnu make can build in a separate dir. see info make page 4.5

https://www.gnu.org/software/make/manual/html_node/Directory-Search.html

[quaint cape]

time to fix acpi driver yee

[astral tartan]

still #GP?

[quaint cape]

yep

[quaint cape]

https://www.tomshardware.com/software/operating-systems/california-introduces-age-verification-law what will this mean for hobby OS?

[mental otter]

If they wana fine people just don’t pay. This shit is ridiculous and I seriously doubt it would hold up in court especially against small hobbyist groups

[quaint cape]

Also wonder what will happen with Linux, can't Linux just prohibit anyone in California downloading it.

[mental otter]

Il just use Linux from scratch if I have to

[vital summit]

it means nothing. because:

• an open source project cant force you to upgrade to the version with the age check
• online centrally managed user accounts arent a thing
• there is no mandatory "app store"
• the age check can be patched out by the end user
• open source projects arent going to pay for the commercial age verification apis theyre peddling
• theres no 'linux inc' to send a fine, especially not ine in silicon valley
• the law cant take effect internationally

so, just ignore it and carry on as normal

whole thing is half baked by someone who thinks: osVendor == (apple || google)

its not even enforceable on windows, unless they enforce secure boot only and microsoft store only

[quaint cape]

true

[quaint cape]

fixed GP on uacpi entry

now i also gotta fix bash stuff

[astral tartan]

bash stuff?

[quaint cape]

fork being broken

[quaint cape]

still debugging bash though

my fork is broken asf btw

[vital summit]

https://tenor.com/view/forky-baked-macaroni-food-broken-gif-17355666

yeah hate it when my fork is broken

[astral tartan]

Feels familiar, I had some fork bugs too...

[quaint cape]

well my fork is always broke

i hate fork

its my num 1 enemy

and context switching

thats also hell

[vital summit]

hatred of fork is why my os exists at all

in 2009 when I was learning from tutorials I was using the jamesM tutorial

it's fork and paging model was just massively scuffed and left broken

not as an "exercise for the reader", was just ... bad.

I hated it so much I went to read the spec on it

the I decided who in their right mind builds a process model like that in the 21st century, and walked my own path instead.

[quaint cape]

Holy this fork shit is making me go crazy

[vital summit]

reject fork return to modernity

[quaint cape]

lol

[chrome cosmos]

i used to hear fork criticised regularly. industry professionals really hated it lol

[quaint cape]

checking for BEOS mounted file system support functions... no
configure: error: could not determine how to read list of mounted file systems
``` huh

me trying to build coreutils

why the

[chrome cosmos]

when you get a message like that from configure, it's usually the last thing it tried from a list

if you search the configure script, you can find the list and what tests it makes

df needs a list of filesystems. du i think has a "stay on this filesystem" option which might need the list too

[quaint cape]

Mathewnd was nice enough to clarify to me

ima just enable the linux option in my mlibc

bash commands finally work

or well kind of work

and yea i have some logs enabled

😭

i spammed logs soo much

[quaint cape]

better version without logs:

[astral tartan]

why does it not return to bash?

waitpid broken?

[quaint cape]

looks like it

theres a lot of shit thats broken rn

[astral tartan]

yeah, bash and coreutils are extremly dependent on POSIX-correct syscalls. You miss 1 edge case and everything breaks...

[quaint cape]

Well I'll have to varify all my syacalls to be posix correct.

[quaint cape]

hmm ima binge watch yt todau

n´prob nkt gonna be much progress

[quaint cape]

lol ima have to update my history file today

[quaint cape]

proper acpi

[vital summit]

mmmmm uacpi

[quaint cape]

ofc

i go mainstream

i like how auroraos is turning out to just be another astral clone

hmm

[spiral field]

is this in tcg (asking as 6063 ops/s seems awfully slow)

[astral tartan]

why is your .bashrc EPERM instead of ENOENT though?

[quaint cape]

unsure why.

[quaint cape]

good question

[quaint cape]

the whole OS is just getting slower and slower with the days passing as i dont care about optimization anymore

[silk valve]

why dont you care tho

[mental otter]

What’s your memcpy/memset functions look like?

There is an easy optimization you can make on x86-64

(rep movsb/stosb)

[silk valve]

what is it?

[silk valve]

oh nvm

[quaint cape]

If I don't have anything that runs on it why care about optimization.

Once i get coreutils ported (will send SS of progress later) I'll actually have something to run on it

[silk valve]

maybe thats a point

[quaint cape]

anyone know how to get mlibc to not freak out once i use malloc or free etc..

[mild shoal]

Iirc malloc/free are not available in ld.so. you have to disable that code using a macro or or allocate in some other way

[quaint cape]

When I've ported bash ima have to write a proper procfs

[mental otter]

@quaint cape Why are you making one giant commit lmfao

[quaint cape]

lol

[mental otter]

I mean why am I talking

😭

I do the same shit

[quaint cape]

dont bother commiting

so i just commit a months progress each monthg

and before that i do five days of rewrite

aka cleaning up logs and shitty stub impls

[mental otter]

Commits are good incase you fuckup lol

[quaint cape]

well i did somehow almost delete my whole fs

which made linux panic

i waas able to recover it though

ZorinOS recovery mode

clutch

[mental otter]

💀

[quaint cape]

yk why coreutils fails like this?

[quaint cape]

.

[mental otter]

I can’t even get bash to compile dawg

🥀

Everything wants to have strange ass errors

[quaint cape]

huh????

[mental otter]

I’m lowk gonna just report mlibc

[quaint cape]

bash is easy to compile

send me the errors

also idgaf if we talk about ur OS in here so feel free to speak

[quaint cape]

huh?

[mental otter]

That’s what I said XD

[astral tartan]

that's why I'm doing my own libc. Everything just works. (well, at least everything I have implemented)

[quaint cape]

well i use bash 5.1

[mental otter]

My mlibc port is based on a 4 month version so

I should update it anyways and refactor a lot of it

[quaint cape]

firstly, use new mlibc

secondly make sure you have

posix

[mental otter]

Yes I have posix BSD and glibc

[quaint cape]

glibc

[mental otter]

Linux fails to compile

💀

[quaint cape]

and bsd

[quaint cape]

same shit

just decided to do ironclad approach and make it myself

[mental otter]

And I ended up having fucking uhhh one of my mlibc patches be just adding more headers

Then everything page faulted at addr0

💀

[quaint cape]

you patch mlibc???

[quaint cape]

which headers?

[mental otter]

Well I have a seperate source tree

[mental otter]

I just copied astrals setup for them

[quaint cape]

well exactly which headers

[mental otter]

Because I did not wana find like all 40 of slender man’s pages XD

[quaint cape]

im so confused rn

Also another thing

ehh

[mental otter]

Let me get the patch file lol

[quaint cape]

astral uses 5.1

like me

so yea

might be culprint

[mental otter]

Why bash 5.1 tbf

Idk my shi is cursed lmfao

@quaint cape Ping me when you get that commit in lol

So I can port in doom

[quaint cape]

if i work my ass off i can get it in later today

[mental otter]

dont over work yourself pls

[quaint cape]

ehh dw

[quaint cape]

btw if i commit it today it will be with a broken waitpid impl

if you feel like youre up for a challenge feel free to try and fix that

[mental otter]

perhapss

[quaint cape]

@mental otter pushed

ima rewrite my code once ur done

[mental otter]

What’s the build system like?

[quaint cape]

ehmm manual .sh files

if you feel like youre up for the challenge change that tooi

[mental otter]

good thing thats what i use to build doom

XD

repo link?

https://git.evalyngoemer.com/evalynOS/evalynOS/src/branch/dev/src/user/doomgeneric/make.sh

[quaint cape]

https://codeberg.org/aurora-org/AuroraOS/src/branch/dev
https://codeberg.org/aurora-org/ports

[mental otter]

🥀

okay uhh

how do i combine these lol

or is it a sub module deal

[quaint cape]

huh?

[mental otter]

git submodules

[quaint cape]

i dont use them btw

[mental otter]

why is the initrd commited lmfao

[quaint cape]

ehmm #lack of build system

[quaint cape]

dev

[mental otter]

[quaint cape]

ty

[mental otter]

oops

[quaint cape]

i manually update the initrd after my sysroot

btw

[mental otter]

pls make a build system for this

[quaint cape]

i really need a better build system

[mental otter]

doom is gonna make that thing huge

https://git.evalyngoemer.com/evalynOS/evalynOS/src/branch/dev/src/build-scripts/generate-initramfs.sh

steal this lol

why did i comment these

💀

like why did i remove that out

[quaint cape]

well i do have that

its outdated asf though

[mental otter]

pls make a decent build system

and remove binary blobs from repo

XD

[quaint cape]

look at meta/ramdisk.sh

[quaint cape]

there are none right

[mental otter]

isnt that the initrd?

also im gonna shill for jinx https://codeberg.org/Mintsuki/jinx

[quaint cape]

my build system aint that bad

./ports/mlibc/mlibc.sh

./ports/bash/bash.sh

then copy the sysroot/usr into initrd/usr

[mental otter]

fym new branch

[quaint cape]

and done

[mental otter]

also where do i get ./ports

clone the repo inside the repo?

[quaint cape]

git clone https://codeberg.org/aurora-org/ports

[mental otter]

fwiw this can also handle host packages too like gcc/binutils

[quaint cape]

firstly ima switch make for meson

and then ima consider using jinx

[mental otter]

I was planning the same at some point lmfao

[mental otter]

sorry i diddnt get to porting

il try asnd build this tomorrow

[quaint cape]

AuroraOS got a new build-system.

[quaint cape]

@mental otter hows it going w porting work=

[mental otter]

im working on fixing my PS.2 driver

[quaint cape]

ahh lmk if you need help

[mental otter]

its almost good

just refaoring a bunch lol

[mental otter]

I changed my ps2 code

It now deadlocks on real hardware

💀

I did do a fix for IRQLs though

[quaint cape]

Sounds like my average change.

[mental otter]

Nah it’s my IRQLs

And shedular spinlocks

Well I think

If I undo the “fix” it works again

[quaint cape]

Reworking my ports impl to use jinx

[quaint cape]

fun

cant build gcc now that i use jinx

yeeeaaaaaaaaaa

@mental otter btw hold off the doom port work until i get jinx working in maybe a week

and meson running etc

[mental otter]

should be easier with jinx anyways

after its setup*

and initramfs generation

because

distrobuting the wad may be a nightmare

i have my script yoink it from IA

[quaint cape]

ill just do like astral and place it in my initrd permanently.

[mental otter]

thats what i do

but for the build system

[quaint cape]

huh something is broken with my jinx impl

time to spend an hour debugging some random shit

[quaint cape]

rip have to study today

hopefully I'll be able to continue working tmrw

[quaint cape]

time to pick up AuroraOS dev

[quaint cape]

think i fixed most issues

time to build bash again

[quaint cape]

Fixed meson

RM'ed RFd the makefile now

meson is better tbh

Backspaces now work

still have some fun page faults to fix though

[mental otter]

@quaint cape How’s your jinx rewrite going?

If everything is setup hopefully I can figure out your build system and get doom going

Because I just finished mine and I have ports file I can port

[quaint cape]

Great tbh

Still ironing our some bugs in my impl

Might push today or tmrw.

[quaint cape]

running into issues with my sysroot

huh

might be a bit delayer

[quaint cape]

added attributes to my vfs

lol

fun times

ima go to bed cya

[quaint cape]

Hmm today ima clean upo

since my implementation yesterday, were well questionable.

[quaint cape]

Rewrote small part of task stuff

[quaint cape]

hmm auroraos has so many bugs ngl

[zealous girder]

claude please fix all the bugs in my OS make no mistakes

[quaint cape]

maybe i should try that

might create 1k other bugs though

[zealous girder]

such is life

[zealous girder]

you have a cute Limine wallpaper, you may be interested in the new Limine Flanterm FB params request

it allows you to keep it into the kernel if you want

[quaint cape]

Really :D

Always wished for a background.

[quaint cape]

Naaa

[zealous girder]

yes! it's quite easy to use, just see the spec, it's at the bottom

[quaint cape]

Will do once I get home

[quaint cape]

I can just load a file

[quaint cape]

my kernel didn't like updating to the newest flanterm version:

[quaint cape]

mind sending me a link to the specification?

cuz i am having trouble finding it

[zealous girder]

you will need to translate \n to \r\n manually in newer Flanterm revisions, there is a reason behind it but the tldr is "don't worry about it kitten"

[zealous girder]

https://codeberg.org/Limine/limine-protocol/src/branch/trunk/PROTOCOL.md

namely at https://codeberg.org/Limine/limine-protocol/src/branch/trunk/PROTOCOL.md#flanterm-fb-init-params-feature

[quaint cape]

🙏

[quaint cape]

wait since when did limine have built in Flanterm???

[zealous girder]

Limine has always used Flanterm internally, but this request is new, it allows the bootloader to optionally pass down to the kernel the Flanterm initialisation parameters so things look continuous and cute

you should not rely on the respose existing of course, but if you wanna use it if it's there, then yeah

[quaint cape]

Doesn't this response also give the benefit of also deriving the background?

Or wait thats what we've been discussing 💀

[zealous girder]

yes

just try it

[quaint cape]

claude please integrate this new Limine feature with my kernel

:D

[zealous girder]

it's honestly really easy to do, i doubt you'd find Claude helpful here beyond wasting tokens lmao

[quaint cape]

-# i dont even have claude code btw

[quaint cape]

.

[quaint cape]

This might seem like a stupid question but should i even bother having my old manual Flanterm implementation as a backup. I feel like if Limine can't produce Flanterm surely my kernel can't (or am i stupid)?

[zealous girder]

i am not sure what you mean, all that request does is provide the parameters you can optionally pass to Flanterm initialisation instead of whatever else you'd default to

the request doesn't need to be implemented by the bootloader, so you should handle it not being returned

[quaint cape]

Currently I'm using Flanterm without any Limine abstraction.
Should I keep this implementation in case if the bootloader doesn't provide the flanterm request?
If Limine fails making an Flanterm window surely I won't be able to make one manually.

[zealous girder]

you should keep that, this request provides an extra way of getting initialisation parameters for Flanterm, it's not an abstraction

you should handle a response not being returned because bootloaders may not implement this and it's not something essential for a kernel to run

[icy herald]

It's not replacing your Flanterm implementation. It allows your Flanterm implementation to inherit the color, wallpaper, etc that Limine uses.

[quaint cape]

ahh.

Now I'm starting to understand.

Maybe should read those docs?

[icy herald]

yes

would be a good idea

[quaint cape]

ohh shit ive misunderstood everything

my bad guys

sorry for wasting your time

[zealous girder]

np

[quaint cape]

so its basically this?

[zealous girder]

yeah

[quaint cape]

huh upgrading Limine is always interesting

why did yall rename so much stuff

[zealous girder]

the new names are better, though note that the ABI is still the same so it's just an API change, but older kernel binaries will keep working as-is

[quaint cape]

why tf doesn't inputs work with the new system lol

the background doesn't transfer either

fixed input

background still stupid

[quaint cape]

@zealous girder sorry to disturb, but what did i forget?

shouldnt this produce the expected behaviour or are there some kind of extra-step needed to get the background working?

[zealous girder]

you need to give Flanterm a proper allocator else the canvas won't work

[mental otter]

I do have a question. Does having a proper allocator also speed up flanterm in any way? Or does it just give things for stuff like the canvas etc

[quaint cape]

Okay

Noted

Ima fix that tmrw

Could you also write some sort of docs for flanterm lol.

[zealous girder]

pretty awesome!

[zealous girder]

speed up? no

the allocator is only using during initialisation, not at runtime

and the internal bump allocator is crazy fast by virtue of, well, being a bump allocator

so if anything your allocators will make initialisation slower

but that's not the point, the point is that the pool of the bump allocator is limited so you cannot use bigger screen sizes, canvases, etc, and also it uses a bunch of preallocated space in .bss obviously, which some may wish to disable

[mental otter]

ahhh makes sense

[quaint cape]

it is really awesome :D

[mental otter]

yeah i think all bugs rn

are just stdin being arse

[quaint cape]

my biggest and most anoying bug is this:

mlibc panic for no reason

[mental otter]

try updating mlibc maybe?

they made the sysdeps system alot cooler

[mental otter]

@quaint cape does running help twice work for you at all?

because the second help

decided to repeat like 20 times

🥀

[quaint cape]

Ehmmm

Considering I can't run one command.

I have a hard time believing I can run two.

[mental otter]

Damn

💀

Not even built ins?

[quaint cape]

Is bash --version built-in?

Cuz that's the only thing I've tested

[mental otter]

no

thats executing bash

echo is a builtin

[mental otter]

Hm yeah

I did end up getting mine working now tho

Just by stubbing every thing possible 💀

[quaint cape]

🙏

i got soo many stubs too

[mental otter]

I had to add some functions into the stubs too

But bash even things I have job control

[quaint cape]

https://codeberg.org/aurora-org/mlibc/src/branch/master/sysdeps/auroraos/generic/generic.cpp

[quaint cape]

you have job control?

👏

[mental otter]

No

But I lie to bash

[quaint cape]

why

[mental otter]

I just like emulate just enough

[quaint cape]

bash can run without

[mental otter]

Because I was getting tired of all the errors

And just wanted to get it to a clean state

🥀

[quaint cape]

which errors?

[mental otter]

So I stubbed things out properly

Scroll up in my channel

Thing was acting cursed AF

[quaint cape]

having no job control doesnt trigger errors

[mental otter]

It prints out something

And it was printing it every time I pressed enter

💀

[quaint cape]

what

how

what did u do?

do you just loop run bash each time

wait thats genius

who needs waitpid

just run bash in a loop for each cmd

[mental otter]

No

I didn’t do that

It did it

On its own

[quaint cape]

then wtf

[mental otter]

💀

[quaint cape]

🙏

[mental otter]

Now you see why I did what I did

🥀

[quaint cape]

🥀 how did u even get to that point

[mental otter]

Desperation

[quaint cape]

yk what is making me go crazy

my fcking jinx shit is bugged

you using jinx jet

yet*

would love to see

[mental otter]

I am

It’s on my repo

I do a mono repo tho

[quaint cape]

like wtf

i didnt change anything

holy

[mental otter]

This shouldn’t be happening

Unless your hard fucking shit up

[quaint cape]

yea

[mental otter]

Jinx uses containers

Check my recipes

[quaint cape]

soon ima start printing all fcking paths

i cant either see what jinx is doing cuz im using meson

so yea

cooked

i havent looked at jinx for so long though

might just let it run and see if all problems just magically go away

[quaint cape]

time for fundemental build system rewrite since Evalyn pointed out my shitty approach thanks btw <3

this is like the third time??

[mental otter]

Do a mono repo this time too

🗣️ 🔥

Oh btw @quaint cape

I ended up using makefiles still

Instead of meson

Still way cleaner

[quaint cape]

bad boy

ima use mesn

[mental otter]

Because now the makefile only makes the elf

[quaint cape]

since its just better

[mental otter]

I’m not a boy

[quaint cape]

me ❤️ meson

[quaint cape]

my god im blind

you lit have it in your name

[mental otter]

😭

Honestly

[quaint cape]

i just think all programmers as boys

[mental otter]

Don’t sweat it

I’ve had this happen

Like more times than I can count

💀

[quaint cape]

though we do have quite a lot of girls in this server

tbh

[quaint cape]

well

yall are quite rare ❤️

lol

1/100

not rly

[mental otter]

I have a thinkpad

With arch Linux

[quaint cape]

i dont use arch btw

[mental otter]

Btw I bet the mlibc panics are from your syscalls mucking up some state?

[quaint cape]

prob

ima just see wherever i return -ENOSYS in my kernel

there's quite a lot of places actually

some syscalls are stubbed with me just returning enosys

which might freak it out.

[mental otter]

Minus ENOSYS?

Idk if mlibc wants it like that

I give it positive ENOSYS

[quaint cape]

well my sys_get_ms is stubbed

wonder if that could be the reason?

[mental otter]

I stub it

By saying it’s always 1970

[quaint cape]

huh

[mental otter]

UNIX epoch

[quaint cape]

well tbf my error codes and stuff are shit

[mental otter]

0 time

[quaint cape]

ima have to rework that completely

[mental otter]

Why return ENOSYS when you can stub it easily

[quaint cape]

when i get bash working its the next thing

[quaint cape]

what time string do you return.

[mental otter]

It’s not a string?

[quaint cape]

unix time format

int

[quaint cape]

<t:1774529618:D>

[quaint cape]

true

also what is that sys thing

i just wrap it in sys_

new mlibc thing??

[mental otter]

new mlibc thing

update

:3

[quaint cape]

rip me

clanker rewrite my sysdep

:D

[quaint cape]

@mild shoal is it true mlibc wants +ENOSYS not -?

[mild shoal]

mlibc expects a positive errno return

e.g. return ENOSYS

[quaint cape]

im stupid

😭

welp

easy fix ig

[zealous girder]

do you manually clear the screen to black at boot?

cuz if you don't it'll look nicer

and boot faster

[quaint cape]

No.

I'm investigating why that happens.

Or well, rephrased I shouldnt clear my screen at boot. Might be old bits of code left that does it though

[quaint cape]

damn

you were right

had a old piece of code who cleared it black.

[zealous girder]

👍

[quaint cape]

now i just need to update mlibc sysdeps right

what is new?

are there any like update details?
