Rails Mime::Type.parse Patches

There are two Rails issues in it's handling of the HTTP Accept header which cause a number of spurious exception emails via Airbrake. I am encountering this on Rails 3.0.7. One of these is fixed in a later version of Rails, but for other reasons I can't upgrade right now. The other bug is still present in Rails 3.2 and in master at the time of this writing. This gist includes some monkey patches you can apply to fix these issues until such time that they are fixed in Rails properly.

Rails Issue #736

Issue #736 is that Rails does not correctly parse a q-value in an Accept header when there is only one content-type specified. For example:

Accept: text/html;q=0.9

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = git@github.com:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:
