Package: dbestfit - a dynamic memory allocator
|
|
Date: March 30, 2005

Version: 3.3

Author: Daniel Stenberg <daniel@haxx.se>

|
I wrote the dmalloc part for small allocation sizes to improve the behavior
|
|
of the built-in (first-fit) allocator found in pSOS (around 1996).
|
|
|
|
I wrote the bmalloc part (best-fit with splay-tree sorting) just for the fun
|
|
of it and to see how good malloc() clone I could make. The quality of my
|
|
implementation is still left to be judged in real-world tests.
|
|
|
|
TODO:
|
|
* Remove the final not-so-very-nice loop in dmalloc.c that checks for a block
|
|
with free fragments (when the list gets longer too much time might be spent
|
|
in that loop).
|
|
|
|
* Add semaphore protection in bmalloc.
|
|
|
|
* Make a separate application that samples the memory usage of a program
|
|
and is capable of replaying it (in order to test properly).
