why?  there really is no reason for it. xulrunner in F-10 has  pyxpcom built. OLPC can and should use the Fedora branch.

If you look at the OLPC-3 branch there is also a number of patches to XULrunner to do with disable of default themes, and removing libgnome and gnomevfs. 

I'm sure that one day they will follow the gnome upstream and migrate to gio and all the new gnome stuff but its not in for 3.0 as far as I can see and I'm not sure its even there for 3.1. I'm investigating too see if the other patches are upstreamable and if the developer has filed patches in b.m.o for them but I'm not there yet. Believe me I want upstream OLPC everything ASAP :)

See the diff.

Please send the patches upstream and to Chris with explanations as to what they do and why they are needed.

And at the bare minimum, I strongly suggest getting explicit approval from upstream (Mozilla) for these patches.  We have a great relationship with Mozilla which is good when we need to seek changes for things such as the EULA issue.  Just throwing in patches without either my or upstream's approval is rather harmful for everyone involved.  Getting approval will at least put it through some review process to make sure the patches don't break something else, which will benefit OLPC and its consumers and its upstream Fedora.  If an OLPC patch ends up breaking things, it makes both Mozilla and Fedora look bad.

OK, this has been highlighted this with Simon (via Danial) and I'll ask him to take that forward for upstream. I'm no real developer, more a Fedora packager working with jkatz and others to help OLPC get things as mainstream as possible and help with the packaging side of things so their dev's can develop.

Christopher, do you know what the Moz plans are with gio and what what extras libgnome gives to Fedora over mainline building without libgnome and friends, or if FF 3.1 or XL 1.9.1 will help with moving away from libgnome like gnome upstream is doing? Or even when there might be a 1.9.1 beta that they can test to see if that improves things :-)

The OLPC Browser people are going to investigate further over the next couple of days to review requirements and file bugs upstream as necessary. I've filed a OLPC tracking bug which I've linked to the external bug tracker on this bug. I think we should leave this one open for tracking the Fedora requirements.

This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle.
Changing version to '11'.

Closing as it looks like its all OK with xulrunner 1.9.1 appart from the requirement on gnome-vfs and there's not much we can do about that atm.
