glide command frequently does what seems like unnecessary extra work

[albrow]

The glide command often seems like it is doing more than what I asked it to do. I'll provide some examples.

1. Start a new go project in an empty directory
2. Run glide get github.com/Masterminds/cookoo
3. Run glide get github.com/albrow/forms

The output I see from command 3 is:

[INFO] Checking dependencies for updates. Godeps: false, GPM: false, gb: false

Maybe I'm missing something, but why is glide looking at github.com/Masterminds/cookoo at all when I just asked it to get github.com/albrow/forms?

Here's another example. I always pin all the dependencies in glide.yaml to a specific version. I would expect glide install to not do anything if I already have the correct version, just like npm install does. However, the output I see looks like this:

It goes on for a while. For a medium project with a decent amount of dependencies, it takes a while for glide install to finish running. When I just added a single package to glide.yaml, and all the other packages have their versions pinned, glide should be smart enough to know that it should leave the other packages alone and just install the one that is missing from vendor.

@albrow thanks for the feedback. I can fill in a little detail here.

First, if you're already at the right reference it should skip updates. That's on the feature/semver branch right now via 1ec3886. I expect that will land on master in the next couple weeks before the 0.7.0 release.

We'll need to poke at glide get to see why it's checking all the things. Thanks for pointing that out.

I have fixed the behavior for glide get and glide up foo.

This turned out to play nicely with several other features we're working on! Hopefully, these things all settled in correctly.

Once feature/semver gets merged, that will solve the remaining checkout issue and we should be able to close this.
