Status: RESOLVED DUPLICATE of bug 1125961

(Core :: DOM: Service Workers, defect, P1)

Description

[Oleg Zasypkin [:azasypkin]]

Flame-kk, Build identifier is 20151115150212

Try to open [1] in b2g browser and observe logcat and "Service Workers" panel in Settings app:

* Logcat: 
I/Gecko   ( 8260): WARNING: child tried to open http IPDL channel w/o security info
E/Browser ( 8260): Content JS ERROR: Registration failed with  [Exception... "Illegal value"  nsresult: "0x80070057 (NS_ERROR_ILLEGAL_VALUE)"  location: "native frame :: <unknown filename> :: <TOP_LEVEL> :: line 0"  data: no] 
E/Browser ( 8260):     at swRegistrationPromise< (https://fxos-performance.github.io/service-worker-simple-fetch/js/app.js:23:7)

* Settings app:  I see SW is listed there, but it disappears once I restart device.

The same page seems to work correctly in latest the Firefox Nightly.

This is a known issue.  You have to disable the network.disable.ipc.security pref on b2g right now.

Yep, that fixes the issue thanks!

I was confused by WebIDE that was showing "true" for this pref, but didn't work for me before I run WebIDE - it turned out that when you request "higher privileges" via WebIDE - it sets this pref to "true" under the hood :)
