Fenix 2.0.0 hangs on splash screen - MacOS X 10.12.3

[ajmas]

Fenix has recently started hanging on the Splash screen. The animation is happening with the three dots, but that is about it. It is not clear what is going wrong.

Tried removing all files in ~/Library/Application\ Support/fenix and ~/Library/Saved Application State/com.intel.nw.savedState/ but no change

What other Fenix related files could I be checking?

BTW a system restart did not help either.

So sorry, this slipped through the cracks. Check your user directory. There is most likely a corrupted file at /Users/Shared/Fenix.localized/servers.fnx. It should be an obvious issue (like [Object object] instead of real values)... fixable by hand.

The file looks ok. There was one path that was no long valid, but fixing it up didn't resolve things. The splash screen stays in place, but I do notice that the service on port 8082 does launch. At the same time testing it from the browser I see the connection opens, but does not complete responding.

Removing the file completely enables the Fenix to start normally. Also, removing the second entry from the existing file also allows it to complete starting, while removing the first entry instead does not.

The contents of the file are as follows:

[
  {
    "id": "60f8a8eebef8d83d73355ad1949559a6",
    "name": "Test",
    "domain": null,
    "port": 8881,
    "path": "/Users/ajmas/Downloads/test",
    "running": true,
    "starting": false,
    "stopping": false
  },
  {
    "id": "ef6d8dd59395f24ab864389c4861a588",
    "name": "My Server",
    "domain": null,
    "port": 8082,
    "path": "/Users/ajmas/Development/projectx",
    "running": true,
    "starting": false,
    "stopping": false
  }
]

This is very odd. Are you using a JS framework or anything on the server that's causing the problem? There is one known framework that caused a similar issue several years ago, but I've never come across anything since.

I have node.js 6.10.2 installed on my computer via MacPorts. Could that be an issue?

Have attached ouput of lsof, in case that helps.

It shouldn't be anything related to the other system apps... I was thinking more along the lines of UI frameworks. Specifically, I'm wondering if you're running into an issue similar to issue #15.

[ajmas]

I am not using that library and I am not sure I am using anything equivalent. I could try investigating myself, but I am not sure how to build a working version of Fenix from the source code in this project?

The root cause of that other issue was a page that wasn't triggering a DOMContentLoaded event... which was causing the screenshot system to fail, in turn blocking processing. It's rare, but worth asking.

Even if there is an issue within Fenix, it is unlikely I'd fix or release a PR at this point. Fenix 3 is done, and it was completely re-engineered from the ground up. I just posted another update about the progress, but the likelihood of this issue being present in Fenix v3 is slim at best. If you're on the mailing list, you'll likely receive an invite pretty soon. If you're not, feel free to shoot me a private note and I'll add you to the release list.
