I meant that in normal case CPU usage is pretty low so it is mostly black. BTW long time ago I got chinook version from http://people.debian.org/~tschmidt/maemo/chinook/osso-statusbar-cpu/ Yesterday I noticed there is also 0.7.x (since June 2008) with 'official' chinook support in maemo-hackers.org repository http://maemo-hackers.org/apt/pool/main/o/osso-statusbar-cpu/ Both of them work fine, they just look different.

It's not anymore refreshing/resizing itself constantly when larger than screen (which with the redraw leak caused the issue and made it easily to crash when it was disabled). I.e. the main issue is solved. The redraw leak is still there though. It can be tested easily just by running: mem-monitor-smaps -p $(pidof hildon-desktop|cut -d' ' -f1) And dragging with stylus the bottom-right resize handle back and forth. Resizing should normally happen fairly rarely though, so this isn't as critical. Btw. The setup application seems to throw some asserts when it's used: From setup startup: personal-launcher-setup[10388]: GLIB CRITICAL ** GLib - g_strcasecmp: assertion `s1 != NULL' failed From opening Settings dialog: personal-launcher-setup[10388]: GLIB CRITICAL ** Gtk - gtk_box_pack_start: assertion `child->parent == NULL' failed - Eero ___ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers

Hi, Am Donnerstag 20 November 2008 schrieb Eero Tamminen: > Could this be kicked out of extras so that people don't "launch" their > devices to oblivion? Just as a side note: I recently had this problem with the osso rss reader. It took me some time to figure out that it was the rss feed reader eating my battery with a 100% cpu load even after a reboot (i was in fact already searching for a cheap replacement battery on ebay). Deleting the rss feed folder under /home/user resolved my problem. I didn't even remember that i ever used and i am not using the rss home applet. So i was pretty surprised to see it running at all ... not to mention the 100% cpu load it did ... I am not saying this to blame anyone. Instead i am saying that this hasn't anything to do with the extras repo. You just cannot prevent these things. I also think like already suggested here that the solution is some monitoring mechanism. If one of those units has a process running at 100% cpu load for more than a few minutes there's sure something going wrong. So this is IMHO the only way address the problem. Unfortunately there's no fan on the n8x0 becoming noisy if the device is under heavy load. So even a simple thing like a taskbar icon indicating a high cpu load and being able to present something similar to the windows task manager might help. People are used to this task manager, so it should be possible to have them using it. But then again in my case they still need to be able to prevent the rss reader from doing the same again after the next reboot ...

Agreed that individual testers gatewaying extras is a bad idea. Some alternate proposals... 1) Require an application to spend some period of time in extras-devel without a major bug submission before promotion. This wouldn't require technical enforcement, just a clear guideline for package-owners to follow. If package-owners behave irresponsibly, the bug-wrangler or some similar role could chastise them and point them to the promotion guidelines. 2) Create a guideline for when a package should be demoted to extras-devel based on negative user feedback. Using the recent personal launcher thread as an example, if an applet really does have a crash/reboot bug, it's filed in bugzilla, confirmed, and ignored for some period of time, that applet probably shouldn't be in extras. That's an extreme example, and in order to prevent frustration the guidelines for demotion must be very clear, and very strictly adhered to. Leaving garbage, buggy, unmaintained apps in the end-user repo is bad juju, but so is pulling well-maintained apps just because they have a serious bug that happens to be found by a high-profile community member (not to pick on Eero who a huge amount of amazing work, but if someone else had found that bug demoting the app would never have been considered at all).

This is exactly why I do not think that any attempts on quality control of Extras are feasible (or even desirable). I am sure everything in Extras has some bugs -- but some have more (or more serious) bugs than others. The answer is not testing of things being put into Extras: that would take a lot of resources, is not scalable and will give rise to false positives and negatives (the tester is the one person in 11,000 who hits a bug and refuses entry, or the tester does not hit the bug and gives a false sense of security). Of course, if Nokia decided it was worth assigning some QA resource and having a repository of software tested to Nokia quality levels that would be fine. But it would be separate from the community repository. The answer for the community repository is a feedback mechanism, both for packages themselves, and for contributors. We need to create an easy way for people to provide feedback on the apps they install from Extras and for people to see the feedback level of both the app and the contributor before they install it. It wouldn't be perfect (there may be a really nasty bug that only affects 10% of people) but it would be much better than what we have today and much better than attempting to impose a quality gate Graham ___ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers

Only personal launcher is enabled and device is booted after enabling it 2. "Use resizable layout" enabled 3. Launcher has enough icons (in one column, icon size = 64) that it it's higher than screen When launcher is disabled, Desktop crashes. The leakage and crash are 100% reproducible. 2&3 seems to be the cause for this. It seems that the resize stuff in the applet is broken and the constant applet flicker is a symptom of this bug: - I think the applet leaks on each resize - It doesn't stop resizing when the area doesn't fit into screen (the area size could be limited to the screen) - Resizing doesn't handle applet unload correctly (disabling happening when applet resizes) Also, making icon size smaller after this so that things fit into screen doesn't help, the applet size allocation remains still higher than screen (can be seen from the flickering and when dragging the applet) i.e. it still leaks & crashes. > I talked to the author.

Now that I was demonstrated the issue[1], I have to admit that the applet configuration was pretty unusual and it's unlikely that people would leave the applet enabled configured like that.
