Gitpod: Stop. Opening. Previews.

[RDIL]

Describe the bug

It seems like recently, a Gitpod update came out.
It now opens previews even if set to open the browser in the config.
This may be a bug, or a feature, but either way I am fed up with it.

Please, make it STOP. This is a BIG pain.

Hi @RDIL, thanks for reporting this annoying-sounding issue.

Could you please provide a repository URL where this error can be reproduced?

Also, please note that onOpen: open-browser can lead to some problems, e.g. because many browsers prevent websites from opening "pop-ups" by default (because they're usually unwanted ads). We try to detect such blocks in Gitpod, and open a notification instead, that asks you if you want to open a Preview or a Browser tab (and when you click on Browser tab, it's no longer blocked, because the user-click tells the browser that the user actually wants to open the "pop-up" / new tab).

I was unable to reproduce this :(

[RDIL]

It only happens on first start

Please provide a repository URL where this issue can be reproduced, or a screencast.

This may be irelevant, but while i was working on gitpod/website where i've notice it opening a preview on page build which i also find pretty annoying.

confirm relevance and i will provide steps to reproduce

@RDIL Thanks! Will take a look now.

@Kreyren This is because of this .gitpod.yml configuration:

https://github.com/gitpod-io/website/blob/d4369f5db174999d3737a7245417729bb36d6d79/.gitpod.yml#L2-L3

I.e., whenever something becomes active on port 8000, Gitpod automatically opens a preview for that port.

Do you use create react app? It does open the website in a browser on start and we are now supporting such calls. I.e. it behaves as it would do locally (open a browser tab).
You can disable that with a command line flag.

Bug confirmed in Gitpod production in Firefox on Mac OS:

• .gitpod.yml says onOpen: open-browser:

• when the port becomes active, port 8000 is opened in both a (blocked) pop-up and a preview panel:

Ah, that should be it.

@RDIL If you start your server with BROWSER=none yarn start, the preview no longer opens.

I think you can also configure BROWSER on a project- or user-wide basis in https://gitpod.io/environment-variables/

Ahh okay, thanks @jankeromnes!
