Mongodb 3.4.x support

[feliixx]

Currently some features of MongoDB 3.4.x are implemented ( collations for example) but aren't documented ( Query.Collation(), views...), and some other aren't implemented at all (see #484 )

In addition, test aren't run against mongo 3.4.x in Travis CI, so it's not very clear whether this serie is supported or not.

So is there any plans to fully support Mongodb 3.4?

If nobody is working on this, I'm interested in doing it !

Hi @feliixx

So 3.4 is supported (but as you said, partially) - I'm very interested in the appName parameter (https://github.com/go-mgo/mgo/issues/484) and was planning on implementing it myself when I had the time - if you'd like to, please do! I'll help however I can :)

Obviously views are a good nice-to-have and may become more of a priority for us in the future, I haven't looked into how much work they'd take to implement though.

The tests are somewhat tricker - I had a quick go at getting them running against 3.4 when we originally forked mgo, but the whole test harness thing is less than perfect... Again, if you want to/can, I'll help however I can!

Thanks,
Dom

As a side note, we'll happily host the 3.4 binaries for the travis tests if you decide to have a crack at it - just let us know and we'll get them uploaded.

@domodwyer Thanks, that would be great ! I started working on appName parameter, see PR #28

Hey @feliixx, thanks for the PR!

I've split this issue into individual feature request issues so we can close them as we go along:

• Collation Add collation documentation #29
• Views Support views #30
• Integration tests Run integration tests against MongoDB 3.4.X #31

I'm going to close this ticket and switch to the above :) Thanks for bringing it up (and if you have any more, please do open issues!)
