I think Crapdroid has different "binding" with it, maybe only Fremantle and Harmattan used it and while they haven't been updated for ages, they dropped it? This are just speculations :P

If the work will be done in a proper way once, the annual maintenance wouldn't be that hard.

I vote a strong NO. Don't get me wrong I'm a big fan of Qt in general, but as long as we're still taking about GTK+Qt4 operaing system, I don't want to have another set of libraries loaded in RAM to open simple web page... I prefer to have more RAM and power for the webpage itself and GTK is sitting in the ram anyway on startup, so why load another stuff just to check the news or other silly stuff online? I would vote for consistency here (system components use GTK, so let's keep it up like it unless the lead of the team decides to change it altogether).

Just my useless 2 cents, I'm not even too active here lately, so if the active devs team has different oppinion, you don't even have to argue with me

(in other words = if the person who will do it will do it in Qt5, but it will still work, I will be happy that it is done at all, after all it's their decision as they are the ones that put their precious time into it)

I say we should stick with GTK too.

And what if we're to rewrite the UI? We might not be able to use the present microb ui in case of a big incompatibility. Is there anyone who knows gtk there?

Assuming we remain ABI compatible with the current tablet-browser-daemon/browser-neteal dbus interface, we should have no problems keeping the current GTK UI working.

managed a quick scan through the maemo removal patch.

a lot of the changes refer to qt, both maemo and harmattan. theres a patch that is linked to maemo bugtracker for flash player bug. some are "if using gtk or maemo" checks reverted to gtk only, which we are still using.

biggest things i can see is a renderer and libconic. the content of the first refers to being able to write directly to image memory so would seem pretty important to me. second, internet connectivity.

the only issue i see with using stock ui at the moment are the dialogs i seem to remember that are in microb-engine. last time i checked (firefox8/9 time), the patches needed adapting to fit but it was still reasonably clear where to put them. as a ui element, i'd rather just have them as part of the actual ui and listen for signal to use them. that way it would make maintenance easier. it also might solve the random issue with dialogs not responding.

even libconic related stuff could technically be seperated out.

Seems like one would need to dig a lot on b.m.o to find all the "remove xyz" and "change xyz" and "do xyz" bugs/patches (including those that relate to gtkmozembed) that would need to be forward ported or otherwise handled.

But, assuming we can track all those down and we can triage all the "local" patches in the Maemo source tree (the ones in microb-engine_20100401-1.9.2-5.2+0m5.diff.gz that get applied as part of the build process through quilt or whatever it is) I think we might actually be able to pull this "update gecko to something recent" effort off

if i get a chance later i'll try to pull latest embedlite and build with gtk2 to see how far we get.

edit: pulling repo now.

Fails during early configure stage due to our gtk version. Needs 2.18+, we have 2.14.7.

Lets start building a list of all the bugzilla.mozilla.org bugs that are relavent. This is what I have found so far, anyone else with more knowledge of Gecko (or bugzilla) than me got any others to add to the list?
https://bugzilla.mozilla.org/show_bug.cgi?id=648156
https://bugzilla.mozilla.org/show_bug.cgi?id=906072
https://bugzilla.mozilla.org/show_bug.cgi?id=1080529
https://bugzilla.mozilla.org/show_bug.cgi?id=653201

Lets focus on the goal of getting a modern Gecko to work on Maemo and then on getting it to work as a replacement for the system browser engine (including talking to all the users of and plugins for the browser engine on a stock Fremantle system)

As for the configuration/packaging stuff, we should reference the actual files used for Fremantle as a guide to what settings we want for it.
