Does node's exec call block meteor application?

Question

I am building a meteor application that creates pdf files from a web page using phantomjs.

PhantomJS is called with node's child_process.exec function within a fiber using Meteor._wrapAsync. When I am using any url like google.com, it is working fine and the pdf is created.

The problem is, I want to capture a site served by the same meteor application at /invoicePDF. But during the execution of phantomjs the site apparently does not load, thus, it cannot load inside phantomjs, which makes finishing the call to phantomjs impossible.

Does it load when you call the phantomjs with your script directly? If not, please register to the [`onConsoleMessage`](https://github.com/ariya/phantomjs/wiki/API-Reference-WebPage#webpage-onConsoleMessage) and [`onError`](https://github.com/ariya/phantomjs/wiki/API-Reference-WebPage#onerror) events. Maybe there are errors. — Artjom B., Sep 09 '14 at 22:07
When phantomjs is called directly, it works. `onConsoleMessage` and `onError` do not show anything. — leoweigand, Sep 09 '14 at 23:52

The solution seemed to be to use Meteor.bindEnvironment instead of Meteor._wrapAsync. Unfortunately, I have know idea why.

You can accept the answer now. Maybe someone will write an answer detailing why this happens. – Artjom B. Sep 10 '14 at 21:37
