1103142 - Cannot connect WebIDE to Flame with e10s disabled

Status: RESOLVED INVALID

(DevTools Graveyard :: WebIDE, defect)

Description

[Jared Hirsch [:jhirsch] (he/him) (Needinfo please)]

STR:
1. flash v188-1 base image onto Flame
2. flash gaia master onto Flame with `DEVICE_DEBUG=1 NOFTU=1 make reset-gaia`
3. open WebIDE
4. select 'Firefox OS (flame)' in the 'devices' dropdown at top right of the WebIDE window

Expected: Debugger connects successfully
Actual: Debugger never connects.

I was having intermittent connection issues last week, but currently can't connect to my device at all.

I do see an error trace in the `adb logcat` output when I select the 'Firefox OS (flame)' option in the dropdown:

W/GeckoConsole( 4165): [JavaScript Error: "error occurred while processing 'listTabs: TypeError: browser.getTabBrowser is not a function

I realize it looks like the log lines were truncated, but I didn't do it--that's exactly what I saw in the terminal output.

OK, update: I was not able to connect *with e10s disabled*.

I re-enabled e10s, then tried flashing gaia and reconnecting WebIDE. It successfully reconnected 5/5 times.

If WebIDE isn't intended to be used without e10s, then feel free to close as invalid :-)

I also forgot to mention that I'm using the latest nightly (currently 36.0a1 (2014-11-21)).

Trying once more from scratch, I'm not able to reproduce the bug.

1. flash v188-1 onto device
2. using Mozilla-TWQA tool, shallow flash ("gecko + gaia") mozilla-central Engineer build onto device
3. flash up-to-date github gaia master onto device via `DEVICE_DEBUG=1 NOFTU=1 make reset-gaia`
4. open webide, attempt to connect to flame

With e10s disabled: WebIDE connects.

Try flashing (step 3) again, leaving WebIDE and USB cable connected. WebIDE is able to reconnect via the dropdown 3/3 tries.

Closing for now, I guess this is a mystery for the ages ¯\_(ツ)_/¯
