Require OS X 10.9/XCode 6.1

[jakirkham]

@conda-forge/core, this is urgent!

This sets the base Travis CI image so it requires OS X 10.9/XCode 6.1 explicitly as the Travis CI default changed appears to have changed to OS X 10.11/XCode 7.3. Please see build, which appears to be the last build on master using OS X 10.9/XCode 6.1. Note that the next build and every subsequent build now appears to be using OS X 10.11/XCode 7.3 by default.

Edit: Proposed similar change to conda-smithy in PR ( conda-forge/conda-smithy#325 ). We should merge that and release it after verifying this works and have merged it.

Hi! This is the friendly automated conda-forge-linting service.

I was trying to look for recipes to lint for you, but couldn't find any.
Please ping the 'conda-forge/core' team (using the @ notation in a comment) if you believe this is a bug.

LGTM should I wait for Travis?

[jakirkham]

We should wait long enough to verify it is picking the image we expect.

[scopatz]

Thanks @jakirkham

[patricksnape]

Great catch @jakirkham! Can't believe they didn't email us or something!

[jakirkham]

Me too. 😞

[jakirkham]

Though are we sure this is doing the right thing? This line doesn't look like what I would expect. Any ideas on how to fix this?

[scopatz]

Weird, because if you look at the "View Config" tab, it says it has the right image. This might be a bug in Travis

[patricksnape]

@jakirkham There is no 6.1 image! We would have to use beta-xcode6.1!

[mwcraig]

Beat me to it by 5 seconds, @patricksnape.

[jakirkham]

Was wondering about this, but it seems to have worked for other people. Will try adding a beta in a new PR.

[jakirkham]

Now with beta. 😉

[jakirkham]

Also raised an upstream issue about erroring out builds where osx_image refers to a non-existent image.

You mean you wish they published things like these?

https://blog.travis-ci.com/2016-09-15-new-default-osx-image-coming/
https://blog.travis-ci.com/2016-10-04-osx-73-default-image-live/

[dopplershift]

Note in the first post they mention simplifying down to:

• osx_image: xcode6.4 (with 10.10)
• osx_image: xcode7.3 (with 10.11 and default)
• osx_image: xcode8 (currently 10.11, but tentatively planned to be 10.12 for this release)

So we shouldn't rely on 6.1 as more than a stop gap.

[patricksnape]

Well yes the blog posts are there but i don't frequently (ever) peruse the Travis blog. A banner on the site would be far more useful for such a breaking change. I can guarantee we won't be the only people to trip up over this.

Removing 6.1 is just a pain for us because we wanted to support back to 10.9.

[dopplershift]

So they communicated, but didn't do it in the way you would have liked? I'm confused, because the reason I subscribe to their blog (and twitter account) is precisely so I see things like this.

[jakirkham]

Thanks for the links @dopplershift.

We should discuss soon (maybe at a meeting) what we want to do about this problem long term. Short term we will need to get back to the image we had.

[jakirkham]

Please see issue ( conda-forge/conda-forge.github.io#249 ) where I have tried to layout this issue. It is mainly informed by @dopplershift xrefs and a little more reading. Let's continue the discussion over there.
