This is a library for dumping and visualizing your heap in MRI. This code is not for the feint of heart. I don't know what versions of Ruby this will work on, and I make no guarantees about which versions I support or anything. If it doesn't work for you, please send a PR!
This. Is. A. Huge. Hack.
- All of them
One problem is that the heap dumped as JSON is really big. I'm having
problems dumping it fast enough. You can adjust the timer interval when you
call Heapfrag.start
, so if you have a large heap, then a slower interval
might be better.
In one terminal:
$ ruby bin/heap2raster.rb /tmp/sock
In a different terminal:
$ ruby --disable-gem -Ilib -rsocket -rheapfrag -S irb
irb(main):001:0> Heapfrag.start(500_000, UNIXSocket.open("/tmp/sock"))
=> true
irb(main):002:0> GC.start
=> nil
irb(main):003:0> x = 5000.times.map { Object.new }; nil
=> nil
Hopefully this gif will help:
- opengl
- glu
- glut
You should use this from Git.
bundle install
rake compile:heapfrag
