apio	dc795ff491	luna: Introduce fail(...), a replacement for expect(false, ...)	2023-02-25 17:45:40 +01:00
apio	d82b3f809b	luna: Add UB sanitizer, for both kernel-space and userspace	2023-02-25 17:45:40 +01:00
apio	37bbc04719	Heap: Fix GPF caused when making many small allocations ... Apparently space was too tight to split(), but we did it anyways, corrupting the next block. This patch fixes this behavior.	2023-02-17 22:47:15 +01:00
apio	4697a16206	Heap: Avoid accessing a block after it's potentially deleted	2023-02-14 20:17:31 +01:00

apio	a7a38d3433	Bitmap: Add a fallible variant of match_region() that does not crash if arguments are out of range ... This lets us call deallocate_memory() with any address and it will not crash.	2023-01-22 14:25:51 +01:00
apio	0126a8fb6e	luna: Add a new SourceLocation class and use that in check() and expect()	2023-01-22 11:43:48 +01:00

apio	944d32de36	Bitmap: Introduce new malloc-aware initialization functions ... Lets us call resize(new_size) instead of initialize(realloc(location, new_size), new_size)	2023-01-21 23:16:50 +01:00
apio	0e607c2fef	Bitmap: Declare more variables as const ... I miss Rust's immutability-by-default...	2023-01-21 23:04:21 +01:00

apio	00ee8314b3	luna: Make Utf8String{De,En}coders return the number of bytes written ... This means we can avoid a call to code_points() in mbstowcs(), which would parse a string twice.	2023-01-14 11:55:19 +01:00
apio	2d2db300b0	libc: Add malloc(), calloc(), realloc() and free()	2023-01-13 20:00:20 +01:00
apio	5fb2ff09c7	kernel, luna, libc: Move the heap code to a common zone, to be used by both kernel and userspace	2023-01-13 19:27:53 +01:00

apio	59db656f25	size_t -> usize	2023-01-13 18:55:05 +01:00
apio	d150c55143	TarStream: Support mode	2023-01-11 18:42:50 +01:00
apio	82b555cf5c	TarStream: Refactor the API to get rid of that awful method in Result ... That method being try_set_value_with_specific_error()	2023-01-11 17:30:53 +01:00
apio	84c82a4e75	luna, kernel: More constness	2023-01-10 19:31:41 +01:00
apio	5aa667c776	luna: Make OwnedStringView::clone() just call from_string_literal()	2023-01-10 19:03:00 +01:00
apio	3ac3d54788	luna: Make check() and expect() output errors in userspace	2023-01-10 19:02:16 +01:00
apio	c83f6c03b5	Bitmap: Add a 'find_and_toggle' method ... Just like find(), but toggles the value when finding it. Avoids doing this manually in MemoryManager and KernelVM.	2023-01-09 18:08:50 +01:00
apio	4287ec6cb0	Bitmap: Introduce a new method 'find' and use it in MM and KernelVM ... This method looks for the first bit with a value, optionally from a starting index, and returns its index. This should be (haven't benchmarked) way faster than the manual way, AKA what MM and KernelVM were doing. This is due to this method using bit and byte manipulation tricks instead of just calling get() until getting the desired result :)	2023-01-09 17:59:52 +01:00
apio	b851dcf9b9	libc: Implement mbstowcs() using Utf8StringDecoder	2023-01-06 21:01:37 +01:00
apio	80f5c790f8	Implement string formatting into libc :) ... Of course, using <luna/Format.h> makes it so simple. No need for duplicate code!	2023-01-06 20:15:43 +01:00
apio	a01b56ed39	CString: Support strcpy(), strcat() and strchr()	2023-01-06 16:20:35 +01:00

apio	a08310ff5e	Add some more errno definitions	2022-12-18 18:09:52 +01:00
apio	4a7e48ed5d	Make sure wchar_t is wide enough to hold all Unicode code-points ... Too bad if it isn't.	2022-12-18 17:14:12 +01:00
apio	1d6092341a	Add a generic TarStream class ... As long as it's in memory, we can use it :)	2022-12-18 16:38:47 +01:00
apio	eadca3d25b	Add nullcpy() ... Invented function to memcpy() with a specific size, but add a null terminator.	2022-12-18 16:31:02 +01:00

apio	9c1c6bb320	Add wcslen() ... I think this can go in CString.h, no need to create a separate CWChar.h or something	2022-12-18 14:33:13 +01:00
