Scumbag 1.9.2 😢

[ixti]

Just for the record, pasting here same I shared on IRC :D

URI.decode URI.encode_www_form :a => [1,2]

On Ruby >= 1.9.3, this outputs: a=1&b=2, which is pretty expected, on Ruby = 1.9.2 it outputs something absolutely insane: a=[1,+2]

I will note that 1.9.2 is widely considered to be broken in general. This is patching 1.9.2's URI.encode_www_form to have a non-broken behavior. If people are depending on the broken behaviors of a broken Ruby VM, this could be a potentially breaking change. I'm not sure how much I care about breaking the code of people depending on the broken behaviors of a broken VM, however. I would personally prefer to drop support for 1.9.2 entirely.
