[Ibija-devel] need of a memory arena system

[Dodji Seketeli]

Hi ibija hackers,


I think there is a need for a memory management system on top of the 
glib-2 memory management system.

Here are the reasons for such a need:

*We need to implement a fast memory allocation/deallocation system to 
boost the whole ibija system.

*Ibija needs to be able to perform memory statistics accounting. The 
type of memory statistics that ibija could provide are the following:
                -Number of allocated bytes between two dates.
                -Number of allocated bytes between two dates.
                -The memory that is still in use.
                -The frequency of allocation of different size.
                -The amount of memory used by ibija
                -The amount of memory used by the application level Java  
classes.
                -etc ..
Notes that by using glib-2 functions like g_mem_profile () we can 
partially provide these informations.

The main idea is that we should implement a type of memory arena as the 
one proposed by the guru David R Hanson in his paper "Fast memory 
allocation and deallocation based on objects life time".
This paper can be downloaded on my personal download area:

You should firts read this paper. Once you have finished reading this 
paper, i think we should discuss the design of the memory system itself.

regards,
