Bananymous 9ba9469bb1 aoc2024: Optimize day12 
There is actually no need for hash maps
 2024-12-14 03:58:11 +02:00
Bananymous 4dbf173ed4 aoc2024: Implement day13 solution 2024-12-14 03:17:55 +02:00
Bananymous 8936cca9cf aoc2024: Implement day12 solution 2024-12-12 17:03:31 +02:00
Bananymous 1c704680a8 aoc2024: Implement day11 solution 
Finally we got a problem where trivial solution does not work

Bananymous 3e36834751 aoc2024: Implement day10 solution 2024-12-10 17:26:39 +02:00
Bananymous 581caff638 BuildSystem: Install base sysroot only once 
Base sysroot is not only installed when creating the syroot directory
for the first time. To get it installed again, you have to either delete
the old sysroot diretory or run clean target

This makes it so its actually possible to edit files specified in the
base sysroot without random hacks.

Bananymous 8b612ba547 aoc2024: Implement day9 solution 
part2 is kinda unoptimized, it should not use expanded input, but I did
not feel like rewriting my parsing code :)
 2024-12-09 16:20:21 +02:00
Bananymous 90820f24a4 BAN: Make HashMap::{insert,emplace}{,_or_assign} return an iterator 
This reduces the number of lookups done into the hash map :)

Bananymous 12a37500b0 Kernel: Fix triple-fault in vitual tty 
This was happening when printing non-utf8 data while having virtual tty
as the debug console.
 2024-12-09 03:35:51 +02:00
Bananymous 3ae6ffdb01 ports/tcc: Create usr/include/sys/ucontext.h 
This file does not have to contain anything, tcc just requires that it
exists.

Bananymous c4e76b391e aoc2024: Implement day8 solution 
I did not feel like optimizing this one, so its a O(n^2) looking over
every cell in the grid. Performs way faster than my optimized day6
solution tho :DD

Bananymous cf9ba737f0 aoc2024: Implement day7 solution 2024-12-07 07:34:21 +02:00

 2024-12-07 01:37:40 +02:00
Bananymous fbc0319cb6 aoc2024: Implement day6 solution 2024-12-07 01:08:08 +02:00

Bananymous 51b6329c86 Kernel: Make backspace \b and delete 0x7F 
This is what `vim` seems to expect and imo makes way more sense.
 2024-12-05 17:34:37 +02:00
Bananymous 72d9e4c1e7 Kernel: Remove accidental debug prints from fcntl syscall 2024-12-05 17:34:32 +02:00

Bananymous 1903079f96 LibC: Fix popen to return correct return value instead of -1 2024-12-05 06:47:10 +02:00
Bananymous b6d0950ee9 LibC: Fix strftime implementation 
This implementation now passes every musl-libc test :)
 2024-12-05 06:46:31 +02:00
Bananymous c1a32a4041 LibC: Implement mktime 2024-12-05 06:43:35 +02:00
Bananymous 8fa443879c ports: Add working tcc port! 
You can actually now compile programs within banan-os!!
 2024-12-04 21:23:09 +02:00
Bananymous 3a465cb94f DynamicLoader: Don't write to pltgot if it does not exist 
This makes `tcc` compile runnable executables
 2024-12-04 21:11:43 +02:00
Bananymous 49133dce48 Kernel: Make pipe check data every 100ms 
This prevents dead lock if read-end does not detect data before blocking
why write-end already notified.
 2024-12-03 21:54:27 +02:00
Bananymous 3b7b6beca5 ports: Allow using banan-os cmake toolchain file for ports 2024-12-03 20:29:38 +02:00
Bananymous 0dd81328ff ports: Unconditionally compile banan-os before building ports 
This allows ports to use any banan-os library cleanly. Ninja is fast on
when everything is already compiled, so it doesn't add too much
overhead.
 2024-12-03 20:29:38 +02:00
Bananymous a668593e6b ports: Don't update ports on every build 
This makes using ports much less painful :)

Bananymous 86859267f0 ports/curl: remove libcurl.la file and use /dev/urandom 2024-12-03 20:29:38 +02:00
Bananymous 88c9f6d233 LibC: Make environ a weak alias 
If user program defines its own global `environ` variable it will still
work :)
 2024-12-03 20:29:38 +02:00
Bananymous 176693dd5a LibC: Implement wcscmp and wcsncmp 2024-12-03 16:21:54 +02:00
Bananymous 62bee04fc0 LibC: Implement dummy utime that just checks file existance 2024-12-03 16:21:18 +02:00
Bananymous 0a5aacfd87 Kernel: Allow open with O_CREAT bypass file permission checks 
call to open(path, O_CREAT|O_EXCL|O_RDWR, 0444) should open file as
read-write although file is created as read-only on filesystem.
 2024-12-03 16:17:34 +02:00
Bananymous 2dec3a6c95 Kernel: Add some sanity checks for existanse of threads 2024-12-03 16:16:50 +02:00

Bananymous e6a2f55a59 Kernel: Closing file backed mmap wont expand the file size 2024-12-03 16:12:26 +02:00
Bananymous 67e9ca56ac Kernel: Create /dev/urandom -> /dev/random symlink 
Most software uses urandom instead of random so this allows it work
normally.
 2024-12-03 16:12:26 +02:00
Bananymous 713daf6cd3 Kernel/LibC: Add support for creating hardlinks 2024-12-03 16:12:26 +02:00
