aleakd

Another leak detector

ALeakD is leak detector and memory analyser. It's composed with a libary that override memory allocation/deallocation and thread creation, which send message to a graphical server application that records all operation of the program.

By this way, you can debug memory leak without closing your application and check which thread is given leaks.

Requirements

• CMake
• Qt version 5

Features

• Communication mode: TCP, UDP, Named pipe (recommended).
• Only compatible with POSIX systems
• View real time per thread usage and memory peak
• Statistics for each: malloc, calloc, realloc, free, posix_memalign, aligned_alloc, memalign, valloc, pvalloc
• Use filter in the GUI to find a memory operation
• Colored view for each memory allocation to view directly the state (free or not free)
• Get backtrace for every memory operation
• View graphical memory usage

Build

Install dependencies:

    apt-get install git cmake qtbase5-dev qttools5-dev qttools5-dev-tools libqt5charts5-dev

Edit the config.h file to modify some options.

Get the code:

    git clone https://github.com/Jet1oeil/aleakd.git && cd aleakd

Compile:

    cmake -DCMAKE_BUILD_TYPE=Debug .
    make

Run the server:

    ./aleakd-server

Run the the program to be analyzed:

    LD_PRELOAD=./libaleakd.so myprogram

Options

You can use the following environnement vaiables:

ALEAKD_SERVER_HOST: host address to the aleakd server
ALEAKD_SERVER_PORT: port address to the aleakd server (default: 19000)
ALEAKD_BACKTRACE: enable backtrace message (default: 1). This can reduce the performance.
