memprof (c) Joe Damato @joedamato http://timetobleed.com What is memprof? ================ Memprof is a memory profiler for Ruby that requires no patches to the Ruby VM. It can help you find Ruby level memory leaks in your application. How to use ========== require 'memprof' Memprof.start # ruby code Memprof.stats # more ruby code Memprof.stats Memprof.stop The above code will output 2 summaries, allowing you to compare which objects were destroyed and which are still around. Memprof.stats also takes an (optional) file name to write the output to a file. Supported systems ================= Currently supporting: Linux (enable-shared AND disable-shared): x86_64 builds of Ruby Enterprise Edition 1.8.6/1.8.7 x86_64 builds of MRI Ruby Snow Leopard (enable-shared AND disable-shared): x86_64 builds of Ruby Enterprise Edition 1.8.6/1.8.7 x86_64 builds of MRI Ruby Support for unstripped binaries and stripped binaries if (and only if) the symbol files live in /usr/lib/debug/ You can get symbol files for system Rubies by installing -dbg packages. For example, on ubuntu: apt-get install libruby1.8-dbg Snow Leopard: x86_64 builds of Ruby Enterprise Edition 1.8.7 x86_64 builds of MRI Ruby (enable-shared and disable-shared) Unstripped binaries only!
