I have a special room that makes Chrome on Ubuntu stop working.

lampholder commented 6 years ago

Trying to reproduce https://github.com/vector-im/riot-web/issues/6145, I:

Went into a test room with no widgets
Opened settings
Changed the power level to speak
Clicked save
Opened settings
Observed that the power level change hadn't persisted
Changed the tint to validate https://github.com/vector-im/riot-web/issues/6159
Clicked save
Switched to a room that had a custom widget in it
Opened settings
Changed the tint and power levels there too
Clicked save
Widget was still 'loading' throughout
Tried to click to another room; the room tile highlight changed but the room didn't change
Clicked a few more room tiles in a panic
Uh oh
Punched in the face with a endless sequence of CORS
Chrome has a bad day and the tab grinds to a halt

Don't know if it's related, but my Riot on another box just got knifed by Chrome, too

This part feels like you were able to race the power level state change request. The rest is just a disaster it seems.

lampholder commented 6 years ago

Yeah, a puzzling disaster too. Switching to that particular room is game over, but if I use an incognito chrome it's fine. Also doesn't seem to affect any of my other chromes/whatever on any other machines.

In [the logs](), we see a tight loop add 501+ event emitters:

2018-02-15T15:05:22.321Z I Switching to room id !fuZaVqmpqEMYoaXNcJ:lant.uk at event undefined
2018-02-15T15:05:22.328Z I newscreen room/!fuZaVqmpqEMYoaXNcJ:lant.uk
2018-02-15T15:05:34.297Z E (node) warning: possible EventEmitter memory leak detected. %d listeners added. Use emitter.setMaxListeners() to increase limit. 501

which takes 12s.

Then we hit a bunch of CORS errors where it seems Riot has request profile information infinitely. This starts 23s after switching to the room.

2018-02-15T15:05:45.706Z E Failed to load user settings: Error: CORS request rejected: https://matrix.lant.uk/_matrix/client/r0/account/3pid?

Unrelated bug that shows up in logs:

Looking at the related logs for this (that occurred prior to this issue being filed), one error comes up repeatedly:

2018-02-15T15:17:06.960Z W %cUnhandled rejection TypeError: _this.props.onWidgetLoad is not a function
    at Object.<anonymous> (https://riot.im/develop/bundles/d73789921a08c2a82bec/bundle.js:157965:46)

which is actually https://github.com/matrix-org/matrix-react-sdk/blob/develop/src/components/views/rooms/EventTile.js#L224

Looks like Quote and QuotePreview do not specify onWidgetLoad, causing an NPE. Unfortunately, onWidgetLoad is not marked as required.

lampholder commented 6 years ago

This looks like a whole mix of stuffs, and (after having deactivated and reactivated the 'replies' option in labs) my 'special room' no longer causes said explosions.

@lukebarnard1 do you think this issue is likely to resolve into something useful, or can I kill it?

lukebarnard1 commented 6 years ago

@lampholder I honestly don't know. It's probably worth having a place for further reports if we ever see this again.

turt2live commented 5 years ago

We haven't had reports of this since, so closing as a one-off-hopefully-fixed bug

jomat commented 3 years ago

Perhaps I have the same issue. Firefox 84.0.1, Element Web v1.7.34-rc.1.

The browser works. Then I open element, it loads some time, then it adds 501 sync listeners, FF says "A web page is slowing down your browser", no further console output, and opening other web pages in new tabs results in infinite loading. Also element still has a spinning circle where the text input fiel should be, and the room list is still "blurred".
