• Sam H wants to implement tabbed windows in the window manager (so that each application would think it had multiple windows open, but the user would see tabs).  The responses included “awesome” and “my personal hero”.  Sam H plans to work on this on github and merge later.
• Thomas wrote some basic window matching code.  It needs some work.
• Our post on the future of Metacity gained quite a bit of mournful attention, including an article in Linux Pro Magazine.

• Sugar Labs want to use Metacity (and not Mutter) in Sugar, and ran into the problem that undecorated maximised windows are necessarily fullscreened.  A patch was provided to turn this off.
• Two on tabs:
  • Sam H wants to integrate tabs into Mutter;
  • Ivan Denker wants to know whether the browser’s tabs and other controls will compete with the desktop’s controls, now that Firefox is rethinking their tab support.
• Thomas Thurman asked about changing the theme format.
• Owen Taylor fixed a crash if Mutter started on the first workspace.

• GNOME bug 163023 – claimed no longer relevant
• GNOME bug 310842 – prefixes, squib from a few days back: what’s the use case?
• GNOME bug 339692 – possible patch; compiz doesn’t like it
• GNOME bug 387139 – possibly actually a gedit issue
• GNOME bug 549886 – property notification has been refactored
• GNOME bug 552303, GNOME bug 552307, GNOME bug 552973 – leaks, plugged

• GNOME bug 569658 – gconf error from last release
• GNOME bug 569812 – undecorating maximised windows leaves a gap; patch; needs testing
• GNOME bug 570044 – apparently disabling gconf loses the titlebar buttons!
• GNOME bug 570047 – autotools fix needed

Checkins on branches/rpnparser

This is the patch mentioned yesterday to rethink the way the parser works. It is actually now over twice as fast, but the difference isn’t noticeable in use on this computer. Perhaps it will be more obvious on slower computers. This has been tested with all the most common themes, uncovering several bugs which have been fixed, but if you’d like to try it out with yours, gentle reader, please feel free.

Inbox Zero

1 day passed from when there were 447 bugs; there are still 445 from yesterday, because new ones have been opened in the meantime; if this continues we will need 7 months. Still on target, though.

A bit short on links this time.  Post something in your own blog about Metacity– either something you’ve read here or something you come up with independently– and we’ll notice and (probably) link it here.  And it’s always good when people link us so we get more readers joining in discussions: link away!

Bugs

• GNOME bug 567757 – live preview in alt-tab – the current bug of the day
• GNOME bug 425899 – clock swings confuse resizes. _NET_WM_MOVERESIZE_CANCEL is now in trunk, but the reporter says that doesn’t fix the problem.
• GNOME bug 553981 – patch was committed ages ago, should have been closed
• GNOME bug 526723 – also fixed ages ago
• GNOME bug 339692 – possibly a struts issue
• GNOME bug 555909 – should the frontmost transient get focus by default? (Yes.)
• GNOME bug 445479 – edge resistance is currently in pixels; should really be in millimetres
• GNOME bug 475038 – the launcher should be telling us on which workspace a program should appear
• GNOME bug 513866 – does anyone know how to make keybinding translations work?
• GNOME bug 437910 – switch resize and menu buttons; patch written; will probably go in

Tobias Mueller has been very helpfully closing bugs which are INCOMPLETE.

Checkins on various branches

There’s been some work on veracity (a test system), and a few other “labs” ideas, checked into svn branches. Veracity will need to be working before some of the bugs we currently have can be closed.

• The patch in GNOME bug 482354 (the one about windows which present to other workspaces, which almost every distro has included) was finally committed.
• GNOME bug 83892, double-click to close, is still being argued over; your chronicler would like to hear some usability experts discuss the reasons given for its inclusion.
• GNOME bug 565241 is a small change to Atlanta, the default theme.
• GNOME bug 160311, requesting the ability to change border sizes independently of the theme, has finally gained a patch which may well be included.
• GNOME bug 345233 has the rather pleasant idea that “Take a screenshot” should be added to the window menu.
• GNOME bug 343824 is a request for the default maximisation keybinding to be a toggle, which seems reasonable.
• GNOME bug 564343, Launchpad bug 298463, and others have said there’s a problem with the print screen button on some distributions.  Still trying to track this one down.
• GNOME bug 565409 believes there should be an option for alt-Tab to display all windows on all workspaces all the time.  What do you think?

We’re not doing the “around the blogs” section this time because they’re mostly repeats of what’s gone before.

• GNOME bug 550670 led to the discovery of GNOME bug 561911, which is also possibly related to GNOME bug 513944, that errors happen because of graphics contexts being of different depths.
• Launchpad bug 296757: gdesklets and Metacity’s compositor apparently don’t play nicely.
• GNOME bug 344072: It has been suggested that alt-Esc should be removed, and alt-Tab should depend on the state of the reduced_resources flag: if it’s TRUE, it behaves as alt-Esc does now, with no popup, and if FALSE, it behaves as alt-Tab does at present.  Gentle reader, what do you think?
• GNOME bug 99335: Should ctrl-alt-del bring up some kind of logout dialogue?  (It does on Ubuntu.)
• GNOME bug 560990: Compilation without the compositor turned on is broken in various ways.  This needs fixing soon.
• GNOME bug 351647: Some kind of command-line option to choose which screens Metacity comes up on might be a good idea.

Things that need writing

Thomas has been working on a test suite for a while, but it’s not ready yet.

Also, before Vectacity gets anywhere near usable, we need to start with an editor.

Around the blogs

• blackphiber was amused by our error messages.
  
• Tombutu covered the Metacity compositor. This seems to have been news for many people, because it generated some buzz on Digg and then found its way to LifeHacker and was also apparently translated into Polish.
• Someone is working on using Metacity with OLPC (and other people are working on using other WMs).
• Owen discusses the use of Mutter, the Clutter semi-fork of Metacity, in GNOME Shell.

Welcome back, gentle reader, to the Metacity Journal, which now talks to you over your cornflakes.  This may not be a long-term feature, but your chronicler thought it worth trying.

It’s been a quiet few days in the world of Metacity, but here’s the latest news.  As ever, feel free to dive in on any of the bugs mentioned.

The recent post about why window matching is currently impossible brings up a chicken-and-egg question.  The window manager doesn’t do window matching because it’s nearly impossible, since windows don’t identify themselves, but windows don’t identify themselves because there’s no need, since the window manager doesn’t support it.  Perhaps adding window matching as an experimental option would help persuade people to add the GTK call to enable window matching in their programs.  Meanwhile, Thomas has suggested making these changes as a new GNOME Goal.

There has been some offlist discussion about reviving Vectacity, the SVG-based branch.  This would make theme editing a fair amount simpler.

Recent bugs

• GNOME bug 560142: AisleRiot and Metacity arguing over fullscreen mode.
• GNOME bug 533277: session restoration problems
• GNOME bug 524468: problem with the screenshot button reported; Thomas cannot reproduce it
• GNOME bug 487356: there are focus issues if a buried window is fullscreen.  This is quite important to fix and is currently at the top of the hitlist.

Around the blogs

• techrepublic says you shouldn’t overlook Metacity, but unaccountably believes that it was only briefly the GNOME window manager.
• wenlong finds Metacity is a useful window manager for use with Avant Window Navigator.

And that’s all until next time.

Bugs

As ever, feel free to dive in with any of these.

• GNOME bug 558058, Launchpad bug 258054, and possibly Launchpad bug 266929 were obscure bugs caused by dereferencing the values of GConf keys which are never null on a properly-configured system; changes in GDM allowed Metacity to be run sometimes without values for these keys, exposing the crashes.  Now fixed.
• GNOME bug 558309: Leonardo Ferreira Fontenelle noted that some names of variables weren’t double-quoted in error messages.  Now fixed.
• GNOME bug 557921: Lennart Poettering suggests adding sound effects to Metacity.  What are your thoughts, gentle reader?

Around the blogs

• Jeremy Visser tells us how to improve the refresh rate of Metacity’s compositor. (Is it worth making this part of Metacity?  Iain?  anyone?)
• SomGNU has a short review of the compositor. Seems the compositor is a hot topic.

There was a lot of discussion about theme patriation on gtk-list for apps such as icanhasedit; almost all the responses were negative.  This diverged into a discussion about window matching, which Thomas has promised a blog post on soon.

• GNOME bug 557536: Ka-Hing Cheung noted on this blog that wmctrl wasn’t able to make Metacity windows stick.  Thomas investigated and found that this is because that part of the EWMH had never been implemented.  It now has been.
• Several bugs cropped up in 2.25.2 almost immediately, which have all been fixed, and we are now on 2.25.5.
• Creating Metacity Themes, which began as a post on this blog, gets its first version on library.gnome.org thanks to Murray Cumming.
• The double-click-to-close issue is still attracting comments.  Gentle reader, if you want this feature, please persuade your distro maintainers to consider it and not us, since we have done it to death here.  When they approve it, we’ll consider it.
• We still haven’t come to much of a consensus over the present() issue, so it may need an overview of the overview.  Your chronicler suspects that the ultimate solution is going to be twofold: we probably need to change the default, and we also need to extend the EWMH to allow apps to hint which behaviour they prefer.

Around the blogs

• Royal HeHe2-ness has a generally favourable review of Metacity’s compositor.

Something to consider

• Do you think it’s about time we flipped the default of the compositor switch to “enabled”?

Till next time…
