Meteor._wrapAsync has been renamed to Meteor.wrapAsync undefined

Question

I have been getting the warning on meteor server start-up. Meteor._wrapAsync has been renamed to Meteor.wrapAsync undefined . Does anyone have any idea why?

Answer 1

This is just to let you know that the previously undocumented API Meteor._wrapAsync has been renamed to Meteor.wrapAsync and officially documented : http://docs.meteor.com/#meteor_wrapasync

If you are not using directly this function in your own code, chances are that packages you are using call Meteor._wrapAsync themselves, if these packages are actively maintained, authors will fix them sooner or later.

Anyway, this is just a warning that won't impact your application, you shouldn't be alarmed because it's not going to break anything.

Answer 2

As of writing (8 March 2015) the package that is causing this is almost certainly CollectionFS. I use cfs:gridfs as the store, so it's out of that or cfs:standard-packages .

cfs:gridfs also has a warning against deployment because it's not production ready... Perhaps this is one of the issues and I hope the package gets some love soon or else I'll have to jump in LOL.

Answer 3

我投票支持cfs：standard-packages作为罪魁祸首，或者两者兼而有之，因为消息是在安装了cfs.gridfs或安装了cfs：filesystem的情况下发生的。
