child_process.exec limits stdout to 200k, throws exception when git command produces more than 200k of output

[barwin]

I'm trying to run some git commands using git-wrapper that generate more than 200k of output. They are hitting the maxBuffer limit of 200k from child_process.exec and throwing an exception (see http://nodejs.org/api/child_process.html#child_process_child_process_exec_command_options_callback)

I think a good workaround would be to use child_process.spawn instead. I'll send a pull-request over to demonstrate what I mean.

This StackOverflow thread shows an example of the error I'm talking about with child_process.exec:
