Some bugs that we'd like particular help testing: * http://dev.laptop.org/ticket/10045 : - Fix loss of audio/video sync in Record activity. Some instances of sync loss may remain, especially if you're running other activities at the same time as Record; we'd like to hear your feedback. * http://dev.laptop.org/ticket/10168 : - Fix Scratch can freeze up after playing sound. See reproduction instructions in the ticket. Thanks! Wow 2 builds in a day! You must be working late ;- At this stage the only difference between os203 and os126 looks like some newer f11 packages, correct? They both work fine (clean installed one and olpc-update the other) and Record-81 is a BIG improvement. Syncing is almost perfect (in my finger snap test :) up to a minute that I tested, operation is snappy, while image display while recording is pretty smooth. However, besides the annoying 5sec silent audio added in the beginning of audio recordings that Mikus described and persists, there is still an old nasty one with data-loss potential. In short trying to record a clip after you recored, played and deleted one, quits the application. Filed here http://bugs.sugarlabs.org/ticket/2041 Other activities worked fine (even Measure 29) Sharing with an XO-1/os15 through an AP was smooth and snappy, initiating activities either from the XO-1.5 or the XO-1. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Before I start plugging things in at random, I need to understand what the circuitry at the input looks like. I assume the schematics can be found on the wiki, but I haven't been able to locate them. Can someone point me at the right page? I think they're referred to as sensors, you might have more luck searching for that.

Re: Reason for the one dot hang found!
[Sorry for the slow response...naturally enough I'm in Europe and falling behind on things.

If (as you say) there is no crash in the logs then I suspect it is related to an infinite loop within the initialization code. Definitely not locking, there is nothing complex or strange about the locking there. And this all seems very familiar. Google for a thread titled cafe_ccic/ov7670 hang on boot from the 8.2 days. I suspect we never fixed that bug upstream and that same commit needs to be reverted from the new kernel. good catch, good call. commit 8815ea29a9bcbab2a3c7fbc28987cac67c2c41d0 is a revert for 6d77444aca298b43a88086be446f943cd0442ef7, and is present in the testing branch (i.e., XO-1 802 and earlier), but not in our current 2.6.31 branch. Wow, ancient history. I don't really remember what I was thinking at the time. Clearly we're seeing yet another i2c flake, something that both Cafe and ov7670 are good at doing. There are a couple of ways in which a rewrite of the i2c controller code could help. Bypassing the Cafe SMBUS controller and letting the kernel bit-bang the protocol would probably work a lot better than what we have now. I can put that on my list, but I can't promise to get to get to it soon - more travel looms. Alternatives: - Just mainline the revert so you don't get burned again. I don't believe there are any other users of the cafe_ccic driver, so nobody's going to complain. - Experiment with the timeout in the do...while loop; s/1/2/ might be enough to keep from reading the TSIC1 register before it's prepared to deal with the world again. jon ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Hi, Wow 2 builds in a day! You must be working late ;- At this stage the only difference between os203 and os126 looks like some newer f11 packages, correct? Yes, that's exactly right. I didn't take the newer F11 updates into the stable branch. http://bugs.sugarlabs.org/ticket/2041 Interesting, thanks. Could you run olpc-log and attach the generated tarball to the bug?

ANNOUNCE: F11-0.88 Alpha2 (os258py)
This is the Alpha2 milestone of our Sugar 0.88 series for XO. Please refer to this page for the current status and download instructions: http://wiki.sugarlabs.org/go/Deployment_Team/Sugar-0.88_Notes Surprise surprise! We now have parallel builds for both the XO-1 and the XO-1.5! I'll make an effort to keep the releases synchronized so people can test on both platforms, but at this time we have no resources to work on platform specific bugs affecting the XO-1.5. == Changes relative to the previous release (os240py) == * Include Sugar 0.88.1 packages (pbrobinson) * Rebase unmerged patches on top of 0.88.1 and shave off a few which are no longer needed. The queue is still very long, help is needed to upstream as many as possible before release * Disabled the hot corners for the frame, as requested by participants of the OLPC Realness Summit. I'm not convinced this is really a gain, but let's first see how many people ask to revert this change (tch, bernie) * Disable sshd startup to save time/memory (bernie) * add IRC and SIP protocols to Empathy client (bernie) * Include the Words activity (bernie) * Add a few small content bundles (bernie) * Pull latest OS updates from upstream (fedora) == Bugs fixed in this release == * xulrunner 1.9.2, attempting to fix font size problems (bernie) http://bugs.sugarlabs.org/ticket/2018 * Prevent double-clicks on entries in the journal from opening 2-3 instances of the same activity (tch) * Rework code to read name widget in the activity toolbar, although there are still ways to fool it (bernie) http://bugs.sugarlabs.org/ticket/1948 * Fix font size in Terminal (jasg) * Fix layout of Record UI, although with a temporary kludge (m_anish) * Reconnect to last AP on startup (erikos) http://bugs.sugarlabs.org/ticket/1883 * Fix the nefarious 1-dot boot hang bug (dsd, bernie) * Make search box in library homepage narrower so it doesn't overflow (bernie) * Avoid duplicated mesh icons in neighborhood view (tch) * Proper Geode video driver fix for the black boxes on buttons bug in GNOME. Note, (frank_huang) https://bugs.freedesktop.org/show_bug.cgi?id=15700 http://dev.laptop.org/ticket/10076 NOTE: for safety, I have not yet removed the MigrationHeuristic option in xorg.conf. Please, try testing without it. == Known bugs == We still have a bunch of serious regressions still open: * ALT-TAB does not switch between apps (tch, quozl, bernie) * Activities sometimes start and remain in window. Window appears at least briefly on all launches. (aa?) * Pulsing launch icon is delayed or absent; occasional activity failed to start message then the activity starts (tch) * Measure sometimes locks up on recording, quitting from frame then brings up metacity dialog activity is not responding (I could never reproduce this myself) * Font in Write is small and text does not fill the screen width (jasg) * Browse: sometimes clicking links in frames creates tabs (need someone to look at this. aa?) * Turtle Blocks: ctrl-c ctrl-v sometimes do not work (walter) * Sugar sometimes restarts; only seen 3 times, twice clicking on journal and once deleting a journal entry (can't reproduce this, maybe a geode driver bug. Next time please check /var/log/Xorg.0.log.old and other logs) All the above bugs seem quite hard. Any help fixing them would be greatly appreciated. == How to help testing == Feedback from the entire community is very appreciated, although we're not planning any further releases of the Sugar 0.84 series. Bugs affecting upstream components are better filed in their respective trackers: * Sugar and activities: http://bugs.sugarlabs.org/ * Fedora 11: http://bugzilla.redhat.com/ * Drivers and OLPC OS customizations: http://dev.laptop.org/ * Paraguay-specific bugs: http://trac.paraguayeduca.org/ If you're unsure where a bug belongs to, use the Paragauy Educa tracker. Please, always assign these bugs to Carlos, who will keep our status summary updated. == Acknowledgments == I wish to thank Paraguay Educa and Activity Central for providing essential engineering resources to make this effort possible. I also appreciate the expertise and support of many dedicated community developers and testers. -- // Bernie Innocenti - http://codewiz.org/ \X/ Sugar Labs - http://sugarlabs.org/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
