is there a specific reason why the ability to install from a GH tarball was removed?

<isaacs> oh, that's because i switched it back, sorry.  we can put it back to doing the .tgz thing, but it wasn't saving properly, and the easiest way to make it save properly was just to make it transform to git:// 
<isaacs> it also caches git remotes now, so if you use the same github repo a lot, it'll be faster to actually use git rather than tarball
<isaacs> also, this means that shrinkwrap can turn "nathan7/npm#master" into git://github.com/nathan7/npm/#0cead032affead
<isaacs> in the _resolved field

hum ok. maybe it wasn't working cause url changed on GH if I recall:

user/repo/archive/{branch or commitish}.tar.gz

the new things are cool but maybe it should do both by checking for git in PATH vs assuming it exists.

I'm somewhat wary of doing magic behaviour based on whether we can find shit in PATH (windows is rather wonky with this) but it seems like an option. There are plans to refactor all this code so we'll probably work it in when we do that.

Here's the issue:

Let's say that you install user/project#master. Then you do npm shrinkwrap. I'd like to know that you shrinkwrap the exact commit where user/project#master points at, so that even if the user pushes more stuff, the shrinkwrapped package won't change.

That's not possible unless we stash the resolved commit data, and we can't even get that if we download from a tarball. Also, git remotes are cached now, so the speed is not as much of an issue (and that was the original motivation to go with the download tarballs).

I'd be happy with a fallback in addRemoteGit that fetches from a tarball if the host is github.

got it, maybe it could just listen for a fail on the process exec of git. #3089 has example of error windows throws.
