Finding a Ruby memory leak using a time analysis

When developing a program in Ruby, you may sometimes encounter a memory leak. For a while now, Ruby has a facility to gather information about what objects are laying around: ObjectSpace.

There are several approaches one can take to debug a leak. This discusses a time-based approach, where a full memory dump is generated every, say, 5 minutes, during a time that the memory leak is showing up. Afterwards, one can look at all the objects, and find out which ones are staying around, causing the

Code of Conduct

This code of conduct applies to members of the East Bay Mobile Hack Night meetup.

Our community is dedicated to creating an inclusive environment for everyone, regardless of gender, age, sexual orientation, disability, physical appearance, body size, race, ethnicity, nationality, religion, or computing experience (or lack of any of the aforementioned).

We do not tolerate harassment of community members in any form. Harassment includes offensive verbal comments related to gender, age, sexual orientation, disability, physical appearance, body size, race, ethnicity, nationality, religion, sexual images in public spaces, deliberate intimidation, stalking, following, photography or audio/video recording against reasonable consent, sustained disruption of talks or other events, inappropriate physical contact, and unwelcome sexual attention. Harassment does not need to be recognized as unwanted or unwelcome by anyone other than the person being harassed.

Be careful in the words that you choose.

# Some members of ruby community continue to misunderstand the interplay of
# signal handlers and exception handling. This is a brief exploration
# via examples. You can run them by uncommenting the invocations at
# the bottom. You can see their behavior with Ctrl-C.

# Some of the examples will require a kill -9 from another terminal to

The final result: require() any module on npm in your browser console with browserify

This article is written to explain how the above gif works in the chrome (and other) browser consoles. A quick disclaimer: this whole thing is a huge hack, it shouldn't be used for anything seriously, and there are probably much better ways of accomplishing the same.

Update: There are much better ways of accomplishing the same, and the script has been updated to use a much simpler method pulling directly from browserify-cdn. See this thread for details: mathisonian/requirify#5
