Allocation

✓ from omnimalloc import Allocation

✗ from omnimalloc import Arena

allocate

✓ from omnimalloc import allocate

Pool

✓ from omnimalloc import Pool

Basic usage: create a static memory arena, inspect stats, and free it.

from omnimalloc import Arena # Allocate a 1KB arena arena = Arena(1024) stats = arena.stats() print(f"Capacity: {stats.capacity}, Used: {stats.used}") # Clean up arena.free()

Debug

Known issues

gotchaArena.free() must be called manually; there is no automatic garbage collection. Forgetting to call free() causes memory leaks.

fix

Use context managers: `with Arena(1024) as arena:` (available from 0.2.0+).

affects: all

breakingIn 0.2.0, all allocator classes moved from `omnimalloc.allocators.*` to `omnimalloc`. Old imports will break.

fix

Update imports to `from omnimalloc import Arena, StackAllocator, PoolAllocator`.

affects: 0.1.x to 0.2.0

deprecatedThe `omnimalloc.mmap` module (memory-mapped arenas) is deprecated and will be removed in 0.4.0. Use `Arena` with `backed='mmap'` instead.

fix

Replace `from omnimalloc.mmap import MmapArena` with `Arena(size, backed='mmap')`.

affects: >=0.2.0

gotchaArena objects are not thread-safe by default. Concurrent allocations from multiple threads can corrupt internal state.

fix

Use `omnimalloc.ThreadSafeArena` wrapper or external locking.

affects: all
