Comment 1

[Jonathan Kew [:jfkthame]]

Similarly, favicons don't appear in the Recently Closed Windows submenu.

This may well turn out to be the same as bug 860578, but I won't dupe it for now until we understand the cause properly.

This feels rather wallpaper-ish to me, but it seems to be adequate to restore the missing icons. They're still only low-res, but I think fixing that is dependent on the more general issue of support for hi-dpi favicons in Places (see bugs 798223 and 854956), so I'm not going to worry about it for now.

I don't really understand this bug. Why is #-moz-resolution a problem here?

Comment 6

[Jonathan Kew [:jfkthame]]

I don't really know, TBH, but I assume it is confusing Places somehow. None of this code is actually familiar to me. :\

Given that this regressed in bug 828508, and the only thing that did was to add the -moz-resolution media fragment, stripping it back off when retrieving the URI seemed a likely fix. Basically, it's not supposed to be exposed to the outside world, it's there only for display purposes.

Comment 7

[Jonathan Kew [:jfkthame]]

Oops, submitted prematurely - I was going to add that the first chunk was sufficient to fix the favicons in Recently Closed Tabs, but they were still missing from Recently Closed Windows; this second chunk of the patch fixes that.

Actually, this doesn't work as well, because if the tab has not been loaded yet (e.g. it's a restored-session tab that wasn't actually loaded), it won't get the icon, whereas retrieving it from the tab's image attribute will provide the proper icon even in this case.

Comment 9

[Jonathan Kew [:jfkthame]]

So, it really does work better like this.

This sounds like a bug, e.g. sessionstore code setting the image attribute directly rather than calling tabbrowser.setIcon.

I don't have much understanding of the sessionstore code, but it looks to me like the image attribute gets saved and restored directly due to being listed in SessionStoreInternal.xulAttributes at http://mxr.mozilla.org/mozilla-central/source/browser/components/sessionstore/src/SessionStore.jsm#253, so that it gets handled by attribute-copying code.

If that's a bug, maybe someone who actually understands the sessionstore code needs to take this and fix it properly. Or if no-one's available to do that at the moment, I'd suggest that for now we use the "wallpaper" here so as to fix the current regression.

Review of attachment 744673 [details] [diff] [review]:
-----------------------------------------------------------------

I think we should fix this the right way, as Dão suggested. The xulAttributes code is quite old and from a time where it probably was okay to handle the 'image' attribute directly.

How does this patch work for you? I unfortunately don't have any HiDPI testing devices.

Comment 14

[Jonathan Kew [:jfkthame]]

(Doesn't apply cleanly on current m-c, fwiw. But it seemed trivial to merge, so I did a build with it to test...)

This doesn't handle the case of "restored" tabs that are closed without having been loaded (i.e. they were "pending", but then closed) -- they go into the Recently Closed Tabs submenu, but without the expected favicon (even though the favicon *was* shown).

I'd actually expect this problem to show up on all systems, not only hidpi hardware. If you open a new tab and load a site that has a custom favicon, then close the tab and look at the Recently Closed Tabs submenu, does the favicon show up?

Comment 15

[Jonathan Kew [:jfkthame]]

And to reproduce the problem even with your patch applied: restore a session with deferred tab loading, but don't actually visit all the tabs (so that they remain "pending"). Then right-click one of the (unloaded) tab titles, and close it. Check the Recently Closed Tabs submenu: the tab you closed will be at the top of the list, but its favicon is missing.

It doesn't with trunk. With the patch this is fixed.

I just tried it and it works for me with the patch applied. BTW, the patch should now cleanly apply to m-c, want to give it another try?

Yes, it applies cleanly now. However, I'm still seeing two issues:

1) Open a new window (not tab). Load a page with a favicon. Close the window. Result: the window is listed in History/Recently Closed Windows, but its favicon is missing.

2) Still not getting the favicon in Recently Closed Tabs if I close a "pending" tab from a newly-restored session. (This is dependent on having the "Don't load tabs until selected" option checked in Preferences - though I believe that's the default.)

This patch contains a simple fix for it.

Strange, it works for me. Did you try to open new tabs and restart the browser after the patch has been applied? I think this might not work with the broken image URLs saved from previous sessions.

Ah, looks better now - thanks. The Recently Closed Windows menu gets the expected icons, and the Tabs menu looks fine too.

You're right - the issue there was with tabs that had been saved by a "broken" version. So I can still reproduce the issue if I go back to current Nightly, load some tabs, save the session, quit; then launch the patched version, restore the session, and close a "pending" tab. But that's an edge case not worth worrying about; it's a cosmetic issue, most people will probably never see it, and it'll resolve itself naturally as sessions get updated.

And as a bonus, this will let us fix bug 860578 more neatly, as Dao requested in comment 3 there.

As far as I'm concerned, yes, but I'd prefer Tim to nominate his patch, as I'm not comfortable trying to comment on the level of risk here in unfamiliar code.

[Approval Request Comment]
Bug caused by (feature/regressing bug #): bug 828508
User impact if declined: Missing favicons.
Testing completed (on m-c, etc.): Landed a couple of days ago, no known regressions.
Risk to taking this patch (and alternatives if risky): The fix itself is very self-contained. It is low-risk although it contains a little cleanup other than just the pure fix. Also it contains a test for previously untested behavior so I think this safe to take.
String or IDL/UUID changes made by this patch: None.
