Touch events are broken in XUL Fennec
Reported from Kairo in IRC that touch events (even single touch ones) are broken in XUL Fennec. We need some testing to verify. We're unlikely to ship another release build of XUL Fennec. We may end up pushing this to the Beta channel if Native slips again (although no one has tested Aurora yet to know if it has this problem).
Adding Kairo. I don't think this will be a priority for the team, but want to track the regression. Metro Firefox should also be seeing this (although they'll eventually want to turn off this silly Parent Process MouseEvents->Child process touch events trickery we did.
The tests at http://limpet.net/w3/touchevents/single-touch.html fail with exception "Permission denied for <http://limpet.net> to create wrapper for object of class UnnamedClass."
Also add romaxa, who is doing the N9 builds, that are XUL as well and show that bug as well (I only tried Nightly versions there).
OK, I did some regression testing, the bug was introduced between the 2012-03-12 and 2012-03-13 13.0a1 mozilla-central builds. This means that Aurora is affected. FYI, sites to use for testing are http://lantea.kairo.at/ (panning the map - which is what I used for regression testing), http://mandelbrot.kairo.at/ (zooming into the set via dragging over a rendered image), http://browserquest.mozilla.org/ (moving the character via tapping on the playing field). Of course, all those are single-touch events, as XUL Fennec doesn't support multitouch. Here's more info on the regression range: Last good build: http://ftp.mozilla.org/pub/mozilla.org/mobile/nightly/2012-03-12-03-11-36-mozilla-central-android-xul/ 20120312031136 http://hg.mozilla.org/mozilla-central/rev/5ec9524de1af First bad build: http://ftp.mozilla.org/pub/mozilla.org/mobile/nightly/2012-03-13-03-11-12-mozilla-central-android-xul/ 20120313031112 http://hg.mozilla.org/mozilla-central/rev/1ca7a94573f2 Checkin range: hg.mozilla.org/mozilla-central/pushloghtml?fromchange=5ec9524de1af&tochange=1ca7a94573f2 I searched for "touch" in the pushlog and found this one: http://hg.mozilla.org/mozilla-central/rev/554ab0a2f470 Peter Van der Beken — Fix for bug 734503 (Add new DOM binding for TouchList). r=jst. Could that be what triggers this bug?
Looks likely to me.
Can someone try setting the dom.new_bindings pref to false and check if that fixes it?
(In reply to Peter Van der Beken [:peterv] from comment #6) > Can someone try setting the dom.new_bindings pref to false and check if that > fixes it? Unfortunately, that doesn't change anything. :(
yep, with disabled new dom bindings nothing has changed
Has anyone tried backing out bug 734503 to see if it fixes the issue?
(In reply to Jim Mathies [:jimm] from comment #9) > Has anyone tried backing out bug 734503 to see if it fixes the issue? I don't do my own builds, but if you get around to doing a try build with it backed out, I can test that.
(In reply to Jim Mathies [:jimm] from comment #9) > Has anyone tried backing out bug 734503 to see if it fixes the issue? Tested with that patch backed out, and single touch events works ok, Sand-trap gape is usable without that patch.
Requesting tracking-firefox13 because this is a regression in XUL Fennec 13 that breaks web content, including popular sites like Google Maps. (We aren't shipping XUL Fennec 13 to the release channel, but we should fix this before it reaches beta.) Peter, would it be reasonable to back out bug 734503 on Aurora until a better fix is found? Would the backout have any risks or side effects?
No, I don't think backing out would have much risk.

https://hg.mozilla.org/releases/mozilla-aurora/rev/064758fe4026 https://hg.mozilla.org/releases/mozilla-beta/rev/7e8c20249a4f This did *not* land in time for 13.0b1 build 1. I'm not sure whether we should hold the build or respin for this...
Verified that touch events work again in 15.0a1 XUL Nightly from today.
