[Valgrind-users] Announcing heaptrack - A heap memory profiler for Linux

[Milian W. <ma...@mi...>]

Hello all,

with the consent of Julian, I'm happy to advertise a new tool of mine:
heaptrack, a heap memory profiler for Linux:

I've written a lengthy article about it with some details here:

http://milianw.de/blog/heaptrack-a-heap-memory-profiler-for-linux

The tl;dr; version is:

- it's an alternative to heap profiling with Massif
- it has a lower overhead
- it collects much more data
- it can runtime-attach to existing processes

I'd like to see more people using it and giving me feedback. You'll need a 
CMake, a modern C++ compiler, parts of Boost, and libunwind. Then it's as easy 
as

    git://anongit.kde.org/heaptrack
    mkdir build
    cd build
    cmake .. -DCMAKE_BUILD_TYPE=RelWithDebInfo
    make install

to install heaptrack. Then, you can run it on your applications:

    heaptrack <yourapp> <your arguments>
    # ...
    heaptrack_print heaptrack.<yourapp>.$$.gz | less

Or attach to a running process:

    heaptrack -p $(pidof <yourapp>)
    # ...
    ^C
    heaptrack_print heaptrack.<yourapp>.$$.gz | less

The source code is tiny, and hopefully easy to read and hack. Patches welcome!

Cheers, happy profiling
