How to bring a (Tight)Array designed as memory watch dog and a fixed
sized, but chunked, memory mapped file together.
I am curious .. (to say the least)
The idea is quite simple (not so much dependend on Array):
- implement a memory-allocator and manager that manages the free space
in a memory mapped file (MMF)
- implement a based pointer type to have address independent pointers
inside the MMF
- provide a way to allocate data-structures using based pointers via
this memory manager in the memory mapped file
- use these data-structures at run-time
The run-time objects will be persistent by default. The based pointer
ensures that links between such objects are pesistent. The memory
manager keeps track of the free areas and used areas of the MMF much
like a file-system.
As I don't want to mirror all D runtime stuff I'm seeking for a way to
gently exchange/swap the normal GC memory allocator through a MMF
allocator, without impacting the normal types, classes etc.
