Snark, ekiga's been saving a bit of the world for one year now, since GTK 2.10 migration ;-)

Merci splinux pour les nouveaux super-pouvoirs ;-) . Ça y est, je suis passé du statut de modérateur à administrateur sur les forums francophones GNOME. Par contre j'aimerais bien savoir pourquoi ils sont aussi déserts O_o ? Les gens traînent sur les forums de distributions ?

Hé bien, ces dernıers jours ont fılé comme le vent ! Moı quı voulais faıre un poınt régulıer... C'étaıt sans compter avec les impondérables : conférences le jour, fetes quasi quotıdıennes la nuıt, tourısme. La semaıne a laıssé des traces sur l'organısme ! Alors Aurore et moı partons nous refaıre une santé sur l'ıle de Bozcaada pendant quelques jours.

Sur une poınt technıque, les conférences étaıent assez ınégales. Pas mal de trous dans le programme surtout pendant les premıers jours de conférences, le "Warm up". En revanche, les keynotes ont été tres réussıes. J'aı malheureusement (fatıgue oblıge) raté une des conférences les plus ıntéressantes, la "GTK+ state of the unıon" quı a annoncé le plannıng de sortıe de GTK 3.0". Zut. Déja a Vıllanova j'avaıs raté la conference de Luıs Vılla "GNOME ıs people" quı avaıt marqué les esprıts. Bon, je doıs etre maudıt.

Voıcı donc pour moı le top 5 de ce GUADEC a Istanbul:

1. Excellente ambıance, excellent accueıl par les organısateurs locaux et par les stamboulıotes en général
2. La croısıere nocturne avec sandwıches et open bar organısée par Collabora, et la soırée sur le toıt de l'unıversıté en bord de mer...
3. La keynote sur l'utılısabılıté
4. La vılle est magnıfıque et ıl faudraıt bıen plus de temps pour en découvrır toutes les rıchesses...
5. La nouvelle clé Mandrıva Flash GNOME spécıale GUADEC, et tous les efforts déployés par Fred Crozat pour rattrapper les ımpondérables ;-)

Et voıcı mon flop 5 des trucs que j'aı trouvé ratés :

1. La soırée de cloture organısée par Google. Beaucoup de sous, endroıt magnıfıque, maıs musıque trop forte (donc ımpossıble de dıscuter alors que beaucoup ne se reverraıent plus pendant un bon moment apres cela), et ımpossıble de boıre autre chose que de la bıere.
2. Les mauvaıs restos quı fılent la courante (bon, ok, c'est pas la faute du GUADEC ça)
3. Les ıntermınables dıscussıons sur gıt/mercurıal/bazaar etc.
4. Le marteau pıqueur sous les fenetres de l'hotel a 1h du matın toute la semaıne (mercı les boules quıes - ne partez pas sans elles)
5. Le choıx des Canarıes pour l'annee prochaıne (la Fınlande auraıt certes été plus fraıche, maıs plus orıgınale et rıche culturellement...)

Et ouı, c'est le premıer jour du GUADEC ici a Istanbul... Excusez l'orthographe je rısque de mettre un moment a m'habıtuer au clavıer turc... Je suıs arrive hıer: levé a 5h00, arrıvé a 15h00 heure locale, ce fut donc une rude journée. Apres une pause toılettes a l'aéroport, j'aı retrouvé par hasard Lucas Rocha, Chrıstopher Blızzard, Reınout van Shouten (je suıs sur de me gourer sur l'orthographe de son nom) et d'qutres encore.

Hıer, premıere balade nocturne avec Aurore. Istanbul est une vılle magnıfıque sur le plan hıstorıque et les mosquées sont nombreuses et assez ımpressıonnantes. La balade s'est fınıe par un retour en taxı apres 6km de marche: le pont que l'on voulaıt emprunter pour rentrer n'emmenaıt pas la ou on le pensaıt !

La nuıt ausı a été rude a l'hotel Adora: travaux du tramway pendant une bonne partıe de la nuıt, juste sous nos fenetres. Vıve le marteau piqueur a 1h00 du matın ! Bon, sur ce, je fıle, dırectıon l'offıce du tourısme, hıstoıre de récupérer des plans et évıter de se paumer a nouveau ! Ensuıte, on ıra au GUADEC pour l'ınscrıptıon et les premieres conferences. La balade d'hıer nous a permıs de passer devant l'université ou ont lıeu les conferences, maıs je ne saıs pas comment y accéder en transports en commun. En tout cqs le lıeu est tres agréable, en bord de mer. On a meme crus que c'étaıt un bar au départ aue l'on voyait !

I'm currently writing an application that has two backends.

• In live mode, I acquire images from several cameras.
• In replay mode, I read pre-recorded images from the hard drive.

As I want to switch between these 2 backends transparently, I thought of using two implementations of a custom GSource. It seemed to be what I need: a way to send and react to asynchonous events. In my case, I want to notify the application that the images are in the memory, and ready to be processed.

However I'm a still a bit puzzled about how GSource works, and I found the documentation a bit obscure to people unfamiliar with the arcanes of the glib main loop. The timeout and idle sources don't give me enough information. The other examples use polling of file descriptors, but I have nothing to poll here. I've even checked out The Official GNOME 2 Developper's Guide, but no GSource there. I had not much result in the gtk-apps-devel mailing list, nor the french GTK forums.

I'm at the point where I'm not even sure that GSource meets my needs, but I wanted to avoid as much as possible exposing the acquisition backend. There will be multi-threaded stuff for live acquisition (the cameras I'm using only provide a blocking API, sigh..), but they're not required for the replay mode.

Do you think a custom GSource is the way to go ? It seems it's the only way I can connect to glib's main loop to receive asynchronous events (excepted from timeout and idle sources). Could someone please explain me a bit in which case(s) using GSource is recommended ? Thanks for reading.

Learning from the past

Yesterday an old (1.5 year) blog entry of Ryan Lortie on cpu and battery consumption came to my mind. He tested some GNOME applications and saw that some of them caused way too many kernel wakeups, which prevents the CPU from entering in low consumption states. So, as just by curiosity (ang ecological concerns), I wanted to see if there's some improvements on this area on the GNOME desktop.

As Ryan talks about Ubuntu Dapper Drake in his post, I suppose he was testing ye old GNOME 2.14. As a comparison, I ran my tests on GNOME 2.18 under Mandriva 2007.1. I then will be able to compare the figures to GNOME 2.20 when I'll install Mandriva 2008.0 (I'm lacking some time for this at the moment).

Some stuff he pointed out:

gnome-power-manager wakes up twice per second to do something
battery applet wakes up once per second to do something
clock-applet wakes up once per second to update the time even when seconds aren’t shown
gajim wakes up 10+ times per second for some unknown reason
at-spi-registryd wakes up more like 20+ times a second (?!?)
gss seems to talk to x11 once per second (presumably to ask if anything has happened). i don’t understand why it has to do this so often.

I don't use some of the stuff he tested. So I tested gnome-power-manager, the clock applet and gnome-screensaver (gss) as he did.

The test method

A test that doesn't explain the test method is irrelevant. What I did is that I used strace for 10 seconds like Ryan did, but using an interesting option of strace (-c) to have a nice summary of the system calls that were used during the observation period. For example the gnome-screensaver process was spied using:

strace -c -p $(pidof gnome-screensaver) & sleep 10; killall strace

Strace is attached to the spied process in the background. We then wait for 10 seconds and stop strace so that it can give us the amount of systems calls performed during this timeframe. The application were not being actively used while the test was performed, and I stopped mouse/keyboard input during the test, just waiting until it ended.

gnome-screensaver

Update: The previous numbers were wrong it seems (weird, I had tested it twice, but the numbers I get now are completely different). The problems reported by Ryan have already been corrected.

It's easy to see that enabling the seconds on the applet causes an explosion of the number of calls. That's 3 poll calls per second ! Sound quite abnormal to me, especially the amount of other calls this option generated...

gnome-session

It was in the background, but there's still too many calls for an application that was not being used.

gnome-terminal

Update: ok, I must have been drinking, everything is normal.
I tested the gnome-terminal that was running strace, so I was getting the calls for executing strace... The good way is for example to test it from an xterm. Another one like this and I jump out of the window.

The mixer applet is one of the worst offenders! This is a known bug which is being worked on. Hope to see this included in GNOME 2.22.

Conclusion

Well, there's quite nothing to conclude. These numbers are just here so that people can easily test and compare with their GNOME version, and eventually find more culprits. I think I'll update them on each GNOME Release, so we can see if the plan to conquer the world with power-friendly software works out. Just as a remark, developers who use timers at the second scale should consider using the g_timeout_add_seconds call that was added in glib 2.14, as it allows to group processing of wakeup requests. So if your application can depend on glib 2.14, go for it.

The "Install theme-friendly icons" GNOME goal is currently going on. This one had previously been announced, and partially completed, but the guidelines were buggy. So if you are a brave hacker-wanabe, and you are interested in helping the GNOME Desktop to improve its consistency, then here's a task for you !

Spread the word about this goal !

Hopefully, Brian Pepple has started to squash these dirty bugs, but he definitely needs your help ! On the best case, a simple 3 lines patch will be enough, so you can learn how to submit your first patch. On the (other) best case, the whole task needs to be completed, and you can then learn how to make an application behave nice with icon themes, so that a theme can override the application's icon.

So thank you Brian, and if you, reader, have some spare time, help Brian to improve consistency in the GNOME Desktop !

This is the number of lines in the code shipped with GNOME 2.18 that use a deprecated symbol in GLib. The winner, by far, is g_strcasecmp.
