27631 2009-07-23 17:06:36 -0700 WorkerContext does not expose the right set of constructors 2023-03-27 05:36:02 -0700 1 1 1 Unclassified WebKit WebCore JavaScript 528+ (Nightly build) All All RESOLVED CONFIGURATION CHANGED P2 Normal --- 1 atwilson webkit-unassigned annevk ap ian ukai oldest_to_newest 134314 0 atwilson 2009-07-23 17:06:36 -0700 Section 5.4 of the worker spec specifies that the following list of constructors are the only ones that should be exposed to WorkerContexts: XMLHttpRequest and all interface objects and constructors defined by the XMLHttpRequest specifications, except that the document response entity body must always be null. [XHR] The WebSocket interface object and constructor. [WEBSOCKET] The EventSource interface object and constructor. [EVENTSOURCE] The MessageChannel interface object and constructor. [HTML5] The Worker() and SharedWorker(url) constructors. We currently don't expose EventSource, but do expose other things like MessageEvent and WorkerLocation. 134329 1 ap 2009-07-23 17:37:07 -0700 It's not clear why WorkerLocation is not exposed per the spec. 134339 2 atwilson 2009-07-23 18:03:32 -0700 For that matter, what about other things visible to workers, like ApplicationCache? 134567 3 atwilson 2009-07-24 08:29:37 -0700 From my email conversation with ianh: > 1) What are the criteria used to determine the list of visible constructors > in section 5.4 of the worker spec? What I felt like adding that nobody complained about. :-) So it seems that the list is somewhat arbitrary. If we want to add more things, we should pursue this on the whatwg list. 196356 4 ukai 2010-03-04 21:54:24 -0800 Sorry, closed different bug 1944182 5 annevk 2023-03-27 05:36:02 -0700 This has been sorted out.
