Bananymous 265b4c2b22 LibC: Implement thread_equal 2025-04-20 03:27:16 +03:00
Bananymous db9db2cc40 LibC: Implement basic pthread mutexes 
This implementation is just calling sched_yield if it could not get
mutex. This is not optimal as it does not allow the CPU to idle, but it
works for now :)

Also I did not test this code at all, but it feels correct :D
 2025-04-20 03:27:16 +03:00
Bananymous 3642eabac0 LibC: Use BAN::atomic_* functions in pthread spinlock 
This allows us not to reinterpret_cast pthread_spin_t to
BAN::Atomic<pthread_spin_t> which is much better :)
 2025-04-20 03:11:41 +03:00
Bananymous 98e05fd179 BAN: Implement atomic functions for normal integers 2025-04-20 03:11:41 +03:00
Bananymous 1ccff9478f LibC: Don't define __tls_get_addr if TLS is disabled

 2025-04-20 03:11:41 +03:00
Bananymous 85f9b585f5 LibC: Don't yield on pthread_spin_lock 
Thats kinda the whole point of spinlocks :D

depending on the current locale

Bananymous 201d752850 Kernel: Allow pipe to write partial data 
This allows potential blocking
 2025-04-19 00:39:42 +03:00
Bananymous 63b3d9875d Kernel: Fix Thread::block_with_eintr* functions 
I was using wrong block function, `block_with_timeout` instead of
`block_with_wake_time`. This caused functions to block way too long and
caused a lot of hangs.
 2025-04-19 00:39:42 +03:00
Bananymous 8cd2d772b0 Shell: Print error if execv fails 2025-04-19 00:39:42 +03:00
Bananymous 2ff3f88b4d LibC: Add support for shebangs 
I implemented shebangs in userspace as I don't really see the benefit of
doing it in kernel space. Only benefit I can think of is executing non
readable scripts but I don't really see the benefit in that.
 2025-04-19 00:39:42 +03:00

flags

 2025-04-17 23:14:46 +03:00
Bananymous 88abbd90dc LibC: Fix strncat 
strncat was using strncpy internally which nullpadded dest until n bytes
were written.

also there was no terminating null byte added if src was shorter than n
bytes
 2025-04-17 23:12:40 +03:00
Bananymous bdbde25784 LibC: Rewrite environ handling 
environ is only allocated on heap when you insert new variables.

environment variables are only `free`'d if they are `malloc`'d by libc
