#202 Web: Prevent “memory bomb” + heap_size argument to supybot.commands.process()

[Valentin Lorentz]

Hi,

When calling a command of the Web plugin (@title, @headers, @fetch, …) with an URL to a specific server (I wrote the code of such a server, ask if you want to see it), Python's urllib will try to store all headers, leading in a forever increasing memory usage (which is very fast).

This patch makes Web execute all commands in a subprocess, which is killed when it tries to allocate too much memory.
