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

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

Ahhhhhhh!

I think this one explains a pin I had to put somewhere else.

+1 to merge if tests pass.

[jjhelmus]

@jrbourbeau was interested in this as well

[jjhelmus]

@beckermr Thanks for the fix, apparently writing code during a meeting is not a good idea 😄.

[beckermr]

LGTM!

[jrbourbeau]

Thanks for handling this @jjhelmus! I'm +1 for adding a msgpack-python <1.0.0 constraint to older (<2.11.0) versions of distributed

[beckermr]

Woops! I got trigger happy on the merge button here! Sorry @jakirkham !

[beckermr]

Ack sorry all. This code will patch all versions of distributed, not just less 2.11.0. We will need to back it out and change it to patch only certain versions.

Ack sorry all. This code will patch all versions of distributed, not just less 2.11.0

The if 'msgpack-python' in record['depends']: line will only match below 2.11.0, newer versions of distributed have msgpack-python >=0.6.0 in the depends list.

Nothing to be sorry about. Thanks for merging 😄
