Now that we're moving to short-cycle releases without binary compatibility guarantees, the system-XULRunner support in the standalone glue is not going to be useful, and will be actively dangerous.

I think I'd also like to remove the standalone glue entirely, but glandium is apparently trying to use it to improve startup time somehow, so we might need to discuss that part further.
With my Debian developer hat on, the /etc/gre.d, ~/.gre.d thingy has always been pointless, even when releases cycles were long. So I'm all okay with that going away. The standalone glue is however useful to avoid using rpath on applications that do use xulrunner/libxul, such as kazehakase, galeon, etc. And this system registration is part of how it works. I'm all for changing the API, though (such as GRE_GetGREPathWithProperties).

With my Mozilla hat on, I think the standalone glue is useful for us to avoid creating our own dynamic loader on each platform to overcome platform limitations and improve cold startup time without relying on a wrapper.

This covers everything except gtkmozembed, which I'll eal with separately.

Looks good to me. I guess applications using GRE_GetGREPathWithProperties today could use a semi-hardcoded path, taken from e.g. one of the variables provided by the pkg-config files on Unix.

Yes, Linux apps should know (somehow) where their target xulrunner is going to be located by the package manager or whatever.
This landed as
but it caused linux bustage*, so I backed it out as

*bustage logs:

Bustage looks like e.g.:
> TestGtkEmbedNotebook.cpp: In function 'int main(int, char**)':
> TestGtkEmbedNotebook.cpp:17: error: 'GREVersionRange' does not name a type

The additional patch landed:
Backed out because something that landed with this may have caused a new orange (Win debug Moth tabview/browser_tabview_bug597248.js):

This can probably land again once we figure out the cause of the test failures.

Does anyone know of any actual documentation for this feature that has been removed? I can't find any to update.

6 years ago and both mention the removed function.
Yeah, I found those moments after posting my question. I take it this means that you need to know where to get your xpcomglue lib instead of having it hunted down for you?
