Bananymous abf7c8e68a LibC: Implement `difftime` 2025-05-04 13:42:17 +03:00
Bananymous 1a38d0c31e LibC: Add g/G modifiers to printf 2025-05-04 13:42:17 +03:00
Bananymous 9ff9d679e9 Kernel: Fix text mode cursor 
Apparently text mode renders cursor in the *foreground* color. My
current clear function used the same color for foreground and background
making the cursor effectively invisible.

Also cursor hiding is now done by moving the cursor off bounds (0, height)
some website I read said this to be valid even on VGA compatible cards
without disable bit.

Bananymous 9f3f8f950a Kernel: Add better panic message for failed shutdown 
ACPI shutdown does not work on the web emulator and running `poweroff`
crashes on `ASSERT_NOT_REACHED()`.

Bananymous 006a196e4a LibC: optimize strpbrk, str{,c}spn, strtok{,_r} 
These matches are now detected with bitmasks instead of looping over the
second string

Bananymous 418678466c Kernel: Fix text mode palette 
ANSI and text mode color indices are not in the same order
 2025-04-23 23:07:47 +03:00
Bananymous 9f4cb5c4dd Kernel: Make pseudo terminals not overwrite old data 
If pseudo terminal buffer was filled, old implementation would overwrite
old data. This is bad if producer is capable of producing more data than
consumer can handle.

Bananymous 73f9de6635 Terminal: Add support for ANSI SGR 8bit and 24bit 2025-04-23 22:03:53 +03:00
Bananymous 12b9c82086 Terminal: Don't wrap cursor right after x == cols 
This prevents scrolling when bottom right scroll is written to
 2025-04-23 22:03:53 +03:00
Bananymous a8edb8870e Kernel: Add support for 8bit and 24bit ANSI SGR 2025-04-23 22:03:53 +03:00
Bananymous dabc3c6cc4 Kernel: Don't wrap cursor immediatly at cols() 
This prevents unwanted scrolling when writing to bottom right cell
 2025-04-23 22:03:53 +03:00
Bananymous cc7c1ad30d Kernel: Add per terminal palette for TerminalDriver 
This allows better color approximation on text mode and in future will
allow user to possibly change the palette
 2025-04-23 18:44:37 +03:00
Bananymous 4d840a8d9a BAN: Make Array more constexpr 2025-04-23 18:40:20 +03:00

Bananymous 35b3c3c98c Kernel: Fix scheduler load balancing 
I was not updating the current queue of the thread which lead to blocked
threads think they were in run queue
 2025-04-23 08:09:51 +03:00
Bananymous 20e17a28cf Kernel: Fix \b handling 
Don't clear the character, only move cursor backwards

Bananymous 28bf2d6374 Kernel/Terminal: Add support for ANSI DSR 2025-04-23 06:14:56 +03:00

Old code was always returning off by one
 2025-04-22 09:55:38 +03:00
Bananymous 96740d6be4 LibC: Make `inet_addr` spec compliant 
I was not doing any error checking, basically i validated anything that
started with atleast a single digit.
 2025-04-22 09:40:46 +03:00
Bananymous b853d29992 Kernel: Fix unix domain socket close detection 2025-04-22 08:36:44 +03:00
Bananymous 33a0f562d3 resolver: Add support for CNAME 
Also rework resolver's send format and convert test-tcp and nslookup to
use getaddrinfo
 2025-04-22 08:36:44 +03:00
Bananymous f8e3ae0525 Kernel: Fix deadlock caused by multithreading 
This allows multiple threads to concurrently call the most common
blocking syscalls:
- read
- write
- accept
- connect
- sendto
- recv
- pselect

This prevents a dead lock when for example process is waiting on a pipe,
but unable to write to it since process is locked.

This is the beginning of starting to remove processes own lock from
syscall and locking only necessary parts.
 2025-04-22 04:51:53 +03:00
Bananymous c790bad667 Kernel: Make OpenFileDescriptorSet thread safe 
Also this allows concurrent calling of read/write/send/recv
 2025-04-22 04:31:18 +03:00
Bananymous d54489bbcb Kernel: Implement MemoryRegion pinning 
This allows process to pin a MemoryRegion into users memory space for
syscall duration without allowing user to munmap the region.
 2025-04-22 04:30:07 +03:00
Bananymous 808c97020a Kernel/LibC: Implement SA_RESTART 
I have been thinking how to do this for a long time but I finally
figured out a semi-clean way
 2025-04-22 02:42:44 +03:00
Bananymous 34e680d792 ports/ncurses: Set some needed environment variables 
ncurses depends on these being set to function properly
 2025-04-22 01:56:34 +03:00
Bananymous 32d543943b ports: Add lynx port 
I have had this for a while but apparently never commited :D
 2025-04-22 01:44:49 +03:00
Bananymous 2632507980 ports/ca-certificates: Add symlink to /etc/ssl/cert.pem 
Some ports try to use this file
 2025-04-22 01:44:02 +03:00
Bananymous f467a9a309 resolver: Resolve hostname to loopback address 
We don't currently support loopback adapters, but some ports were trying
to resolve it.
 2025-04-22 00:48:26 +03:00
Bananymous 5c9710c78b LibC: Implement `strcoll_l` 2025-04-22 00:48:26 +03:00
Bananymous 107b31a0b5 Kernel: Fix E1000{,E} driver for older qemu versions 
This patch adds clearing of *Interrupt Cause Registers*, which allows
older qemu versions to send new interrupts. Apparently this is not
needed on newer releases.
 2025-04-22 00:31:13 +03:00
Bananymous 028c7a822f LibC: Don't define SCHAR_MAX in locale.c 2025-04-21 22:21:40 +03:00
Bananymous 18f5f98e62 General: Mark USB hubs done in README 2025-04-21 22:13:31 +03:00

Bananymous b774f147da LibC: Implement dummy pthread_attr_{get,set}detachstate 
detached threads are not yet supported, but this allows implementation
to make sure threads are joinable.
 2025-04-21 19:58:01 +03:00
Bananymous 2a5921b9c9 LibC: Implement pthread_barrier 
This is not fully working but should be fine for most cases
 2025-04-21 19:53:38 +03:00
Bananymous 60cb392e97 LibC: Implement pthread_barrier 
This is yet another bad sched_yield implementation :D
 2025-04-21 19:52:14 +03:00
Bananymous d012c538c3 LibC: Add PTHREAD_SPIN_INITIALIZER 
This is not posix, but current implementation allows adding this
 2025-04-21 19:47:00 +03:00
Bananymous 1c88d0d7f7 LibC: Implement pthread_rwlock 
This uses the same dumb sched_yield instead of actually blocking :D
 2025-04-21 18:48:47 +03:00
Bananymous 773b8de8ba LibC: Refactor pthread type definitions 2025-04-21 14:38:40 +03:00
Bananymous 5d8dd090a9 LibC: Implement `pthread_once` 2025-04-21 14:17:17 +03:00
Bananymous 2cbfe70a28 DynamicLoader: Don't leak fds 2025-04-20 18:18:32 +03:00
Bananymous 16dbfbb267 LibC: Make limits.h `*_MAX` usable in #if comparisons 2025-04-20 17:15:20 +03:00
Bananymous 99fc7817c6 Kernel: Cleanup stack alignment assembly 2025-04-20 16:55:18 +03:00
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
