// NOTEs
//
// All allocations below DIRECT_MMAP_THRESHOLD exist inside of memory "Regions." A region
// consists of a Region_Header and the memory that will be divided into allocations to
// send to the user. The memory is an array of "Allocation_Headers" which are 8 bytes.
// Allocation_Headers are used to navigate the memory in the region. The "next" member of
// the Allocation_Header points to the next header, and the space between the headers
// can be used to send to the user. This space between is referred to as "blocks" in the
// code. The indexes in the header refer to these blocks instead of bytes. This allows us
// to index all the memory in the region with a u16.
//
// When an allocation request is made, it will use the first free block that can contain
// the entire block. If there is an excess number of blocks (as specified by the constant
// BLOCK_SEGMENT_THRESHOLD), this extra space will be segmented and left in the free_list.
//
// To keep the implementation simple, there can never exist 2 free blocks adjacent to each
// other. Any freeing will result in attempting to merge the blocks before and after the
// newly free'd blocks.
//
// Any request for size above the DIRECT_MMAP_THRESHOLD will result in the allocation
// getting its own individual mmap. Individual mmaps will still get an Allocation_Header
// that contains the size with the last bit set to 1 to indicate it is indeed a direct
// mmap allocation.
// Why not brk?
// glibc's malloc utilizes a mix of the brk and mmap system calls. This implementation
// does *not* utilize the brk system call to avoid possible conflicts with foreign C
// code. Just because we aren't directly using libc, there is nothing stopping the user
// from doing it.
// What's with all the #no_bounds_check?
// When memory is returned from mmap, it technically doesn't get written ... well ... anywhere
// until that region is written to by *you*. So, when a new region is created, we call mmap
// to get a pointer to some memory, and we claim that memory is a ^Region. Therefor, the
// region itself is never formally initialized by the compiler as this would result in writing
// zeros to memory that we can already assume are 0. This would also have the effect of
// actually commiting this data to memory whether it gets used or not.
//
// Some variables to play with
//
// Minimum blocks used for any one allocation
MINIMUM_BLOCK_COUNT :: 2
// Number of extra blocks beyond the requested amount where we would segment.
// E.g. (blocks) |H0123456| 7 available
// |H01H0123| Ask for 2, now 4 available
BLOCK_SEGMENT_THRESHOLD :: 4
// Anything above this threshold will get its own memory map. Since regions
// are indexed by 16 bit integers, this value should not surpass max(u16) * 6
DIRECT_MMAP_THRESHOLD_USER :: int(max(u16))
// The point at which we convert direct mmap to region. This should be a decent
// amount less than DIRECT_MMAP_THRESHOLD to avoid jumping in and out of regions.
MMAP_TO_REGION_SHRINK_THRESHOLD :: DIRECT_MMAP_THRESHOLD - PAGE_SIZE * 4
// free_list is dynamic and is initialized in the begining of the region memory
// when the region is initialized. Once resized, it can be moved anywhere.
FREE_LIST_DEFAULT_CAP :: 32
//
// Other constants that should not be touched
//
// This universally seems to be 4096 outside of uncommon archs.
PAGE_SIZE :: 4096
// just rounding up to nearest PAGE_SIZE
DIRECT_MMAP_THRESHOLD :: (DIRECT_MMAP_THRESHOLD_USER-1) + PAGE_SIZE - (DIRECT_MMAP_THRESHOLD_USER-1) % PAGE_SIZE
// Regions must be big enough to hold DIRECT_MMAP_THRESHOLD - 1 as well
// as end right on a page boundary as to not waste space.
SIZE_OF_REGION :: DIRECT_MMAP_THRESHOLD + 4 * int(PAGE_SIZE)
// size of user memory blocks
BLOCK_SIZE :: size_of(Allocation_Header)
// number of allocation sections (call them blocks) of the region used for allocations
BLOCKS_PER_REGION :: u16((SIZE_OF_REGION - size_of(Region_Header)) / BLOCK_SIZE)
// minimum amount of space that can used by any individual allocation (includes header)
