=== Collaboration Issues ===
* Activities were reliably sharing between 2 XOs in the same School server mesh, and also in simple mesh. This was tested with write/distance/chat/memorize
* Some XOs were connected to APs, while still running salut in channel 6.
These could very reliably exchange presence info(XOs showed in meshview/received activity invitations/joined public activities) with each other and also with the ones connected to the SS in channel 6.
However, no application traffic was able to be shared. This was tested in many activites including write/chat/pippy/connect and others.
These XOs had different msh0 ip subnets(one was SS,msh0=172.18.x.x, other was AP,msh0=169.254.x.x).
Perhaps this explains why the traffic data wasnt sent? But again, presence traffic was shared fine.
* Some times when joining a Chat the activity wasnt responding. Keystrokes were shown int he edit box.
The log displayed : "groupadd: group 10019 exists Creating mailbox file: File exists".
The bug wasnt consistent though
Seemed identical to 6499
* We couldn't manage to make read share. Perhaps this is still related to 6483. More testing was done subsequently and bugs have been filed.




Activity sharing is quite fragile in official-703. See [[Collaboration Network Testbed]] for more detailed results.

* One telepathy-salut crash was seen but it was probably not [http://dev.laptop.org/ticket/6310]. More testing needed.
* Last but not least: The inhibit-idle-suspend flag stops the XO from suspending automatically.
I was under the impression that a suspended XO will wake with MDNS packets. However, I removed the inhibit-idle-suspend flag and suspended for 15min. When resumed, all the XOs were failed in avahi. It seems that MDNS packets didnt wake it.
Are there different rules for resuming from automatic suspend vs resuming from manual suspend?
This needs to be further looked into.

DRAFT



Pending successful completion of the Release Checklist, we will release build candidate-703 as official-703.

Breaking Changes from official-656

Activities must be installed separately.

Motivation: OLPC cannot presently afford to maintain more than one stable build. Therefore, we have decided to provide a "blank slate" which must be customized with activities and content bundles at installation time. (Some people have asked OLPC to provide a single step upgrade/customization path but no resources have been allocated to this task).


Finding Activities

OLPC hosts many Activities and several activity packs including:

To use an activity pack:

  1. Download it.
  2. Unzip it onto the root of a USB key.
  3. Insert the USB key into your XO and reboot. (Hold the X game key while booting if your machine's firmware is unlocked.)

Linux will boot and unpack each of the bundles into place.

  • Another future option for installing 'activity pack' bundles, from console use xo-get.



What's the recommended way to upgrade?

The recommended method is to run Olpc-update to the new build, and then to reboot with a G1G1 Activity Pack key inserted.




Improvements from official-656

See OLPC_SW-ECO_4 for a more precise list of the changes, indexed by ticket, that lead from candidate-699 to candidate-703. To summarize, we added:

  • OFW version Q2D14 which will delay firmware updates until power is available.
  • Newer library indexing software which fixes a recently introduced typo.
  • Better Spanish localization of the library and of the X and console keymaps.
  • A new telepathy-salut which should lead to more reliable long-running Chat sessions and that may avoid the "Christmas tree" effect ([1]).
  • A new libabiword that fixes a Write sharing crasher.


Notable Current Bugs

  • #6777 Library bundles cannot use non-ascii characters in their file names
  • #6729 Read doesn't save the PDFs it opens (when sharing)
  • #6532 SD Card Corruption: partition table gets corrupted on ext3-formatted SD cards on suspend/resume
  • The contents of a USB key didn't show in the journal. So couldn't install activity bundles from the USB through the journal.


Customization Issues

  • Customization key wont install if the activities or library directories had already been created as root.


Activity Issues

  • #6773 TamTamJam: Recorded microphone slots don't playback
  • Couldnt add feeds to news reader because clicking "+"/dropdown on the feeds tab didn't do anything.

(Almost) full activity testing results for Update.1 RC-2, all results are from build 702

Network Issues

  • WEP and WPA initially worked fine and were tested several times; however, after some time, no XOs could connect to the WPA access point. The icon also disappeared in one of the XOs.


Collaboration Issues

Activity sharing is quite fragile in official-703. See Collaboration Network Testbed for more detailed results.

In particular, Read sharing is not a reliable mechanism for transporting PDFs between laptops. Other less bandwidth-intensive activities such as Write, Distance, Chat, and Memorize were somewhat can be shared with somewhat more reliability.
