malloc
This project is about implementing a dynamic memory allocation mechanism
The first implementation was created accordingly to stepik guide.
Works on 🐧 Linux and 🍏 MacOS
Compile library
Clone: $ git clone --recursive https://github.com/olehsamoilenko/malloc.git
Compile: $ make
Compile debug version: $ make debug
Again usual version: $ make re
Run tests
To run tests please use: $ ./run.sh ./test
To show malloc performance please use:
$ ./run.sh /usr/bin/time -l ./test on 🍏 MacOS or
$ ./run.sh /usr/bin/time --verbose ./test on 🐧 Linux
Use library
$ gcc program.c [-lft_malloc -L .]
$ ./run.sh ./a.out
Features
- memory defragmentation
- unmap-ing unused pages
- memory hexdump with
show_alloc_mem_ex() - debug enviroment variable
DEBUG - test framework:
$ make debug && sh tests/run_tests.sh - integrated with ls:
$ ./run.sh 'ls -lRa /'(sorry, only for 🍏 MacOS) - nm cleared of redundant functions
