Re: [platform-swt-dev] Browser/XULRunner 1.9.3

[Grant Gayed <Grant_Gayed@xxxxxxxxxx>]

Hi Ryan,

Unfortunately WebKit does not provide
something similar to JavaXPCOM.  I agree that JavaXPCOM provided very
useful functionality, and was the main push for porting the Browser's mozilla
implementation from its original Linux-only form to also run on Windows
and OS X as of eclipse/swt 3.3.  The motivation for switching to use
WebKitGTK+ whenever possible for SWT.NONE-style Browsers as of eclipse/swt
3.7 is for the interface and functional stability that it will bring.  Mozilla's
new policy of zero frozen interfaces reinforces this change even more strongly
going forward.

That being said, the example you mention
brings up an interesting point.  Although JavaXPCOM is out of the
picture as of xulrunner 2.0, at least some functionality that JavaXPCOM
enabled can be done in JS instead.  For example, the headers observer
could be implemented with:

String string =
   "var httpRequestObserver
= {observe: function(subject, topic, data) {alert('called!');}};"
+
   "var observerService
= Components.classes[\"@mozilla.org/observer-service;1\"].getService(Components.interfaces.nsIObserverService);"
+
   "observerService.addObserver(httpRequestObserver,
\"http-on-modify-request\", false);" +
   "observerService.addObserver(httpRequestObserver,
\"http-on-examine-request\", false);";
browser.execute(string);

This has me wondering if there could
be value in continuing to work with xulrunner versions >= 2.0 (SWT.MOZILLA-style
Browsers only).  This is not a 3.7 plan item, but I've created a feature
request to investigate this, time permitting ( https://bugs.eclipse.org/bugs/show_bug.cgi?id=327696
).  I don't think this is critical at this time because as I previously
said, support will be continued for JavaXPCOM users for xulrunner <
2.0.  However as time passes it may become desirable for some clients
to use JS instead if they can realize the benefits of xulrunner >= 2.0
in return.

Yeah, my apologies on the version.  The bug fixes
I was looking at are still are listed as 1.9.3, but they renamed it to
2.0.

This is very disappointing news.  Is there any equivalent
to JavaXPCOM with WebKitGTK+?  There were a lot of things that could
only be done easily with the Browser using JavaXPCOM (header listeners,
etc).

Hi Ryan, 

I don't think there will be a XULRunner 1.9.3 release, the next release
that I can see is 2.0.  XULRunner 1.9.3 was previously proposed but
I think has been discontinued. 

XULRunner 2.0 will have significant API changes compared to pre-2.0, with
no frozen C++/Java interfaces (new policy), and will not ship with JavaXPCOM
jars .  SWT is not planning support for xulrunner versions >= 2.0,
since WebKitGTK+ is available as an alternative for SWT.NONE-style Browsers.
 Support (bug fixes) for xulrunner versions < 2.0 will continue,
so swt clients using JavaXPCOM will be supported, but must continue to
prescribe a XULRunner version < 2.0.

Are there any plans/timeline for support of the newest release of XULRunner
in SWT?  There are several changes in 1.9.3 I'm eager to get my hands
on.  I know it's still in beta, but I was just wondering if integration
or testing efforts start before the release.

Cheers,
Ryan Levering
