Description User image Serge Gautherie (:sgautherie) 2010-11-29 07:37:48 PST
still has
56                 nsIGlobalHistory.idl \
57                 $(NULL)

But nsGlobalHistoryAdapter.cpp was removed by bug 568691.

Then it seems this interface is not registered (anywhere) anymore.

1) Was it intended or just missed?
2) Are there other interfaces in the same case?
Comment 1 User image Serge Gautherie (:sgautherie) 2010-11-29 07:43:10 PST
42  * @status DEPRECATED. This interface is still accepted, but new
43  *         implementations should use nsIGlobalHistory2.

Then you might want to take Gecko 2.0 as an opportunity to remove this interface completely.
But that's just a reminder, not a request.
Comment 2 User image Benjamin Smedberg [:bsmedberg] 2010-11-29 07:45:58 PST
This was an intentional change. We should remove the interface.
Comment 3 User image Serge Gautherie (:sgautherie) 2010-11-29 08:19:50 PST
Stop exposing/building an interface that is actually unavailable now.
Comment 4 User image Benjamin Smedberg [:bsmedberg] 2010-11-29 08:20:53 PST
No, I don't want to remove it now because extension code which doesn't actually use it may still be trying to use Components.classes.nsIGlobalHistory.

Wow, I'm puzzled!
So you say you want to "keep (building) the code in the tree, yet not register the interface anymore"?

(I wonder what good that does.
Maybe take bug 603031 + bug 615219 as an example.)
Comment 6 User image Benjamin Smedberg [:bsmedberg] 2010-11-29 08:49:07 PST
No, I'm saying we should remove the interface *after* we branch for Firefox 4. The *interface* is still present in Firefox 4, but there are no implementations of it, so it's vestigial.

Hum (I'm not sure I fully understand, but), in other words, am I right to say that:
*this bug is Future for now (until FFv4 branches)?
*ChatZilla is now required to use nsIGlobalHistory2 (bug 615219) to keep working with Gecko 2.0b2+?

So, we are quite far from Firefox 4, we still don't have an implementation of this interface, so whoever tries to use it is likely just not doing what he thinks.

Benjamin, would you be fine to actually do the removal now?  We can reach tracked add-ons authors through the AMO team, though at this point I expect those being just onowned and unmaintained add-ons.
Comment 9 User image Benjamin Smedberg [:bsmedberg] 2012-05-03 10:32:03 PDT
Yes, please remove.

Remove nsIGlobalHistory (if we want to)

I assume benjamin's review here is also valid as a SR for the interface change, and after all this was already in the plan from a long time.  So this can land.
