Re: [Server-devel] [Sugar-devel] 32(+) XO-1's on Mesh Potato 2 as AP on XSCE

http://www.mail-archive.com/telepathy@lists.freedesktop.org/msg05699.html

Also, I wrote a patch for Avahi, which allows to customize the TTL time,
after which the disconnected buddy actually gets removed from Avahi's
list ::

 Problem description: 32 XO-1 laptops are booted and registered to a
 school server, and all 32 icons are visible in neighbourhood, but the
 icons persist after any XO leaves.  Sugar-0.96 (yes, really), on OLPC
 OS 12.1.0.

 Sorry, I don't know how the XO is being asked to leave; forced power
 off, shutdown request using power button, or shutdown using Sugar
 menu.  This would be something to investigate.

 My experience is that a shutdown request using power button is similar
 in effect to typing shutdown -h now via sshd, and this leaves the
 SSH client stranded without the connection clearing down.  Perhaps all
 that is required is time for the ejabberd connection to time out?

 Perhaps this is fixed in a later release of Sugar, and an upgrade or
 field change can be recommended?

[Server-devel] Some queries regarding PATHAGAR workflows

[Ajay Garg]

Hi all.

I have been playing with the public book-server
http://108.171.173.65/latest/ that Sameer let me know some time back
(thanks a lot Sameer, again !!)

However, I have some queries regarding some workflows (and I found it best
to query all you guys, so that the maximum information could be shared) :)
::



1)
On the home page http://108.171.173.65/latest/, I only see a Log in
option.
However, how do users get registered/created at first place?

2)
What is the notion of a user in the book-server?
In other words, what can a user do after logging in, which cannot be done
without logging in?


Looking forward to some pointers :)

 You can add users through the django_admin interface (command line)

 User account in pathagar has rights to edit/add/delete the database

Compiling thee kernel

[Ajay Garg]

Hi all.

I cloned the kernel source-code from git://dev.laptop.org/olpc-kernel, and
ran make from my Dell x86-based laptop. The compilation ran to completion
successfully.


However, I noticed that marvell module (in drivers/media/video) was not
compiled. As a very vague guess, the reason seems to be that compiling this
module requires the presence of I2C network-bus, which does not seem to be
the case with the x86-based Dell laptop (which used SMBus).

Is my reasoning correct?
Is there a way at all to (cross-)compile the marvell module on the x86
Dell laptop?

I will be grateful for any pointers :)


(I am sorry if I sound too stupid.)

Ajay

Re: Compiling thee kernel

[Ajay Garg]

Hi James.
Thanks a ton for the reply 

Here are the steps I followed on my x86-based Dell laptop::

a)
cd ~


b)
git clone git://dev.laptop.org/olpc-kernel


c)
cd olpc-kernel


d)
make


e)
Wait many minutes (if not hours).
Everything runs to completion.


f)
Haphazardly edit drivers/media/video/ov7670.c.


g)
Now, run make again.

Because of the haphazard editing of the file in step f), the build should
break.
However, it doesn't, and it runs to completion as before.


h)
At any time, there is no object file (.o) or kernel-object (.ko) file
whatsoever in the directory drivers/media/video/marvell-ccic.


i)
Because of observation of step h), and the fact that ov7670.h is used in
the file drivers/media/video/marvell-ccic/mcam-core.c,
I doubt if the marvell module is being compiled at all.


j)
Moreover, the I2C VS SMBus has stemmed into my imagination, looking at
the file drivers/media/video/Kconfig :)


Note that following the steps f) and g) after haphazardly editing a
different file like drivers/media/video/tvaudio.c DOES break the build.
That means that I am at least following the right ways to break the build :P


James,
please let me know if you require any more info.

Thanks again for the help !!

Transient-Issues with game-keys on XO-1.75

[Ajay Garg]

Hi all.

I have a XO-1.75, SKU198, OLPC-CL1 model.
The firmware is Q4D28.

I seem to be having the game-keys (the X, tick, square, circle
keys) that sometime work and sometime not.

To have a more clear picture, I ran showkey -a, and pressed the keys
numeral times. I observed that ::


  * the square key was always grabbed.
  * rest of the 3 keys were sometimes grabbed, and sometimes not.


Has anyone else run into this issue? Could this be a firmware issue?
Or have my 3 out of 4 keys gone berserk at the same time? :P


Will be thankful for any opinions.

RAM in XO-1.75-models

[Ajay Garg]

Hi all.

As per http://wiki.laptop.org/go/XO-1.75, the RAM in XO-1.75 is

   DRAM memory: 512 MB or 1GB DDR3 dynamic
RAMhttp://en.wikipedia.org/wiki/DDR3_SDRAM;



Is there any specific criteria as to which models have 512 MB, and which
have 1 GB?
I, for example, have 512 MB of RAM, on a CL1 model.

Re: Is it possible to hack the rotate key?

[Ajay Garg]

Thanks Gary and Paul.
I tested Moon on build 28 on XO-4; and the rotation caused the canvas to
be redrawn appropriately.




Paul,

I have two queries ::

a)
In Moon's code (as already told by Gary), the size-changed signal is
used to call the callback that redraws the canvas.
So, in this case, is the size-changed signal a result of the
rotate-key-event (KEY_SWITCHVIDEOMODE), or size-changed signal is
generated via some another mechanism?

b)
Is the behaviour of olpc-kbdshim the same for a XO-1.75 and a XO-4 (as far
as that code is written to either run a command
attached to the event (currently /usr/bin/olpc-rotate), or pass the  event
through, but not both is concerned)?

 if there were consensus that running the command _and_ passing the

 doesn't feel right to me.

 but i also think gary's on the right track by suggesting you look at
 other window events to learn of the rotation changes -- after all,
 rotation doesn't require a button press.  it can be caused by manual
 xrandr invocation, or simply by someone typing olpc-rotate left.

   I tested Moon on build 28 on XO-4; and the rotation caused the canvas

 okay.  was that unexpected?


No.. just wanted to state it explicitly that it worked :)





  
   Paul,
  
   I have two queries ::
  
   a)
   In Moon's code (as already told by Gary), the size-changed signal is
   used to call the callback that redraws the canvas.
   So, in this case, is the size-changed signal a result of the
   rotate-key-event (KEY_SWITCHVIDEOMODE), or size-changed signal is
   generated via some another mechanism?

 i don't know.


ok :)






  
   b)

 yes.  and for XO-1 and XO-1.5 as well.


Great.. thanks !!!

Activating a XO-1.5

[Ajay Garg]

Hi all.

I have received a new XO-1.5.  When I  boot it, it shows activation lease
not found.

As per http://wiki.laptop.org/go/XO_1.5_B2, i tried the following steps ::

a)
Downloaded the signed-image
http://download.laptop.org/xo-1.5/os/candidate/13.1.0-21/31021o1.zd, and
copied it to the root-directory on my USB-drive.

b)
Downloaded the corresponding
http://download.laptop.org/xo-1.5/os/candidate/13.1.0-21/31021o1.zd.zsp.fs1.zip;
renamed it to fs.zip, and copied it to the root directory of my USB-drive.

c)
Inserted the USB-drive into the XO-1.5

d)
Powered on the  XO.

e)
Immediately, pressed the 4 game-keys.

f)
Upon seeing the message Release the game keys  to continue, unpressed the
keys.
Image installed successfully.

g)
A firmware was flashed.

h)
Removed the USB-drive.

i)
Rebooted the XO.

j)
Again, the message Activation lease not found was seen; the image failed
to boot into sugar :-( :-(



What step have I done wrong?

Looking forward to some  help, as I need to get the XO-1.5 running :-\

Re: [Sugar-devel] Hacking onto the appearing and hiding of OSK

[Ajay Garg]

Hi all.

Just wanted to know that whether the signals used in the Write activity

 'size-allocate',
 'request-clear-area',
 'unset-clear-area',

are usable anywhere else too?



I can see that  these signals are being listened by class
DocumentView(Abi.Widget); however, the source of this signals is unknown
(or at least inconspicuous).

Is Abi.Widget the source of these signals? If yes, that would mean that
these signals cannot be used anywhere else on  a generic basis, right?

 In my opinion, in this case, your hack, is exposed to the user, in a way
 that is worst than do not have a solution at all. In fact we spent a lot of
 time trying to do terminal work with osk (right now, if the cursor is
 behind the osk, the text area is resized and scrolled), but need more work.
 Be prepared to invest time to do it right, a quick hack will not be a good
 solution. Another problem using the terminal with the osk you will find, is
 the lack of auto-completion and a few keys useful in the terminal but not
 in normal use.

 May be Speak can be best solved, if you move the text input to the top of
 the canvas, like we did in Record activity. Chat is a little more
 difficult, you can move the input to the top, but the history will be
 hidden. (Btw, I don't know why all the chat interfaces show the history
 from bottom to top instead of top to bottom)
 Anyway, these are suggestions, should be better have a agreement with the
 Design Team, Gary  Manuq.

Re: [Sugar-devel] Hacking onto the appearing and hiding of OSK

[Ajay Garg]

Hi all.

A simple solution was found :)

I hacked the KP_Prior and KP_Next keys, and now they are used for
making-window-smaller and restoring-original-window-size respectively :)

All thanks to
   * /usr/share/X11/xkb/keycodes/evdev
   * sugar/src/jarabe/view/keyhandler.py



Just one thing I noticed when  I tried to have the above keys take effect
ONLY in ebook-mode (via the evtest --query test), that when I ran this
again and again via the suprocess module, the XO-4 behaved very
erratically. However, when I made the keys take effect irrespective of the
test of ebook-mode, things worked cool. However, I will keep on looking
into the reason.


Thanks a ton to all :)

Re: [Sugar-devel] Hacking onto the appearing and hiding of OSK

[Ajay Garg]

I agree with Gonzalo and Gary; this is just a makeshift solution for the
time-being, so that activities like Speak, Chat, Terminal are not rendered
completely unusable in ebook-mode.

Ideally, the best solution would be to have the OSK-appearance-and
window-shrinkage on automatic and tied-together basis (without needing
any manual intervention).

 example in a textview.
 
  I can't understand what you are trying to do. The user should press the
 key to enlarge/shrink the activity window? Does not look like a good
 solution.

 +1

 OSK behaviour should be automatic, no user intervention (other than
 perhaps some manual view scrolling when there is no active focus to get
 into view). If we are missing cases (and we are currently), then these are
 bugs to be fixed and/or features to be landed (often GTK3 related upstream
 targets, but occasionally Sugar/Activity related patches). We made great
 progress in 13.1.0, hopefully we can finish off this effort ready for
 13.2.0.

 I applaud these goals.

  If the above seems ok, then all that is needed is a way to figure out

   Hi all.
  
   I wish to fix the bug, where some activities (Chat, Terminal, Speak
 for
   instance) are rendered unusable in the ebook-mode, due to the OSK
   covering
   the area of text-input.
   I have figured out a generic working solution for this - the idea is
 to
   minimize the activity windows when the OSK appears, and move back to
   the
   normal size when the OSK disappears.
  
   I thought we had a different approach under development: to scroll the
   window up in the case of the text view being occluded by the OSK?
 
  Yes, there are patches in GTK3 and Sugar for this, though with some
 issues
  still needing worked through. One activity that we managed to push hard
 to
  get polished was Write, it needed to be a special case as it doesn't use
  normal gtk widgets. My (rough) understanding of the implementation is
 that
  GTK first looks for a scrolled view and tries to scroll it so that the
  cursor/focus rect is kept in view [1], if no scrolled view is found it
  scrolls the canvas [2].
 
  [1] the Write behaviour here is not ideal as the abiword widget
  implementation for the text area didn't allow for extra padding at the
  bottom of the view, so the text being edited is hard up next to the OSK
  rather than with some extra space so the text selection handles stay
  visible.
 
  [2] I think there were patches in GTK3 Sugar so that the activity canvas
  area was automatically placed in a scroll view, so the toolbars are
  guaranteed to stay in view, but not sure if this landed.
 
   This
   should be doable for activities that have scrolling windows, such as
   terminal and chat. Speak, which doesn't scroll could be refactored to
   put the textview on the top instead of the bottom of the screen. (I
   suspect that whatever solution we have will involve some intervention
   in some activities.)
 
  Yes some intervention in activities will still be needed, and the first
  thing to do if you want any of this auto scrolling support is make sure
 your
  activity is ported to GTK3! ;) FOr activities like Speak I'd posted
 mockup
  images to a previous mail list thread showing how moving the text input
 area
  to the top of the UI would work well (the eyes will just peek over the
 top
  of the keyboard and the OSK can be hidden when the text is submitted for
  speaking).
 
  
   I have tested the re-sizing the windows; however, to make the fix
  work
   everywhere, I was thinking of the following algorithm ::
  
   What does resizing the window do? What other activities have you
 tested
   it on?
 
  Some activities will become quite unusable if auto shrunk, scrolling I
  think is better, we're lucky if the original developer planned for
 landscape
  and portrait aspect ratios...
 
  Regards,
  --Gary
 
  
  
   a)
   Just before/after the OSK appears, make the current window smaller.
  
   b)
   Just after/before the OSK disappears, revert the current  window to
 its
   original size (if not already).
  
  
   This requires a way to know when and how the
 appeareance/disappearance
   of
   the OSK is triggered.
  
   How can this be done? I am sure there must be some gobject-signal for
   this -
   I just can't seem to figure it  out by manually

 XO-4 does not support rotate the screen yet. You should try with other
 models.


Ok, thanks for the info :)






 Just figured out one thing via Nitika's XO-4-Touch (thanks to Nitika for
 bearing my brunt of the testing-questions !!), that pressing all 4
 game-keys at once, does toggle the appearance of the OSK !!

 So, I guess, we DO have a point, wherein we can hack resizing of the
 window.

 So, now I have another question ::
 Where is the code for handling game keys handled (as far as appearance
 and disappearance of the OSK is concerned) ?
 In Firmware? In Sugar? Elsewhere?


 The keyboard appear because you pressed a key (you don't need press the 4
 at once, any key will show it)

 Detecting osk show/hide. is more complicate than should be, in my point of
 view. Probably, because the idea behind this is the osk should appear and
 hide in a automatic way based in the widgets needs.

 I think you should check the class DocumentView in widgets.py in Write
 activity, to see how the signals are used. Carlos Garnacho worked on this.


Ahh.. that's a nice pointer Gonzalo :)

It seems that only size-allocate and request-clear-area are the signals
to be considered (not sure though; again, can only  verify after a couple
of days).

If these signals are in fact emitted when the OSK appears/disappears by
pressing a game key, I think we should be done. We would have found a hack
:)

Keeping fingers crossed, and waiting eagerly for my XO-4-Touch to arrive.

a)
Ensure that the XO is in normal-mode, and no activity is turned on.

b)
Turn to ebook-mode.

c)
Open Speak activity.

d)
OSK appears automatically this time.

e)
Now, pressing the game-key does not cause the OSK to go away :-\
It is only when the keyboard key is  pressed, does  the OSK disappear.

f)
If the game-key is pressed again, the OSK appears.


Gist :: Game-key works fine and consistently, when the OSK is required to
be made appeared.
  BUT, it does NOT WORK, if the OSK has been launched automatically.


So, it seems that just hacking onto the game-key won't help :(

 No. Will not work, because the osk will appear if you touch over a input
 widget.
 The game keys are not the expected way to show the osk.


Hmm.. which brings us back to square one :(

Let's try another way :P

Is there a way, so that we may know whether we are in ebook-mode, or
normal-mode?

If yes, we can at least make the windows smaller for newly launched
activity-windows.

 Yes, there is a ebook switch event:

 Jan 24 01:14:28 xo-1e-89-0d kernel: input: OLPC lid switch as

 Jan 24 01:14:28 xo-1e-89-0d kernel: input: OLPC ebook switch as

Great !!

Now a good weekend exercise, to bring this message from kernel to user

Hacking onto the appearing and hiding of OSK

[Ajay Garg]

Hi all.

I wish to fix the bug, where some activities (Chat, Terminal, Speak for
instance) are rendered unusable in the ebook-mode, due to the OSK covering
the area of text-input.
I have figured out a generic working solution for this - the idea is to
minimize the activity windows when the OSK appears, and move back to the
normal size when the OSK disappears.

I have tested the re-sizing the windows; however, to make the fix  work
everywhere, I was thinking of the following algorithm ::

a)
Just before/after the OSK appears, make the current window smaller.

b)
Just after/before the OSK disappears, revert the current  window to its
original size (if not already).


This requires a way to know when and how the appeareance/disappearance of
the OSK is triggered.

How can this be done? I am sure there must be some gobject-signal for this
- I just can't seem to figure it  out by manually browsing the code, since
I don't personally  have a  XO4-Touch with me :-(

Any ideas, please?  :)

 Server :: ejabberd on CentOS (XS-0.7)

 Hence, buddies are not able to see each other.



 Some additional notes ::
 ==

 a)
 Both servers are running with the same  ejabberd.cfg file, as attached.


 b)
 On CentOS, following are effective, before starting ejabberd ::

service iptables stop
service ip6tables stop


 On Debian-6, following are effective, before starting ejabberd ::

iptables -t mangle -F
iptables -t mangle -X
ip6tables -F

 c)
 Both servers are running the same ejabberd codebase (the patched version
 of 2.1.10), containing all the patches in

 http://dev.laptop.org/xs/repos/stable/olpc/xs-0.7/source/ejabberd-2.1.10-1.el6.olpc1.src.rpm
 (Thanks again Jerry).

 More  importantly, the issue of
 https://support.process-one.net/browse/EJAB-1533 is fixed via the
 persist-all-pubsub.patch (Thanks Daniel Drake).
 The buddy-properties are persisted, as seen via ejabberdctl dump db.txt
 (as seen on both CentOS and Debian).



 
 However, very surprisingly, the __get_members_ready_cb still receives
 NOTHING in the failure-debian case  (see FAIL-shell.log),

   but receives the buddy-properties in pass-CentOScase (see
 PASS-shell.log).

 #



 d)
 Most importantly, on both the servers, the Send XML Stream log is seen
 in /var/log/ejabberd/ejabberd.log; however, the members-changed signal is
 seen only in the CentOS-ejabberd case, but not in Debian-6-ejabberd case.

Location for source-rpm of ejabberd, being used in XS-0.7

[Ajay Garg]

Hi all.

I am wanting to share the sugar-activities, via gabble protocol.

As a first step, I installed
http://dev.laptop.org/xs/OLPC-School-Server-0.7-i386.iso on a VirtualBox,
and did the xs-setup example.org  step.
(As the second step, I chose manual networking, to configure the
virtual-image as per my network. After the networking was set, I could use
the Chat activity between two XOs fine :) :)


Now, I wish to have this sharing done, with only ejabberd running (in other
words, without installing all the other components that come along packaged
with the XS).
The ejabberd version (as shown by rpm -qa | grep ejabberd) is
ejabberd-2.1.10.el6.olpc1.i686

Regarding this, I wanted to know the source of the ejabberd rpm being used
::

(i)
Is it the vanilla Fedora rpm that is being used?

(ii)
Or some OLPC-specific patches come along (which would mean there must
be a corresponding OLPC src-rpm for the same :) )



I will be thankful for any pointers :)

 http://dev.laptop.org/xs/repos/stable/olpc/xs-0.7/source/


Thanks Jerry; as  usual you were on the spot :)
I could build and install the rpm on Fedora :)


Just one more question:
===

I still see that there are some differences (mainly related to the served
domain names, and allowed clients that could register fields) between
the XS-0.7's ejabberd.cfg, and the one I just installed on Fedora.

Although I know the steps to change these settings to make ejabberd work,
but I still wonder whether the ejabberd-installed-after-building-
http://dev.laptop.org/xs/repos/stable/olpc/xs-0.7/source/ejabberd-2.1.10-1.el6.olpc1.src.rpmshould
be the same as
ejabberd-found-on-XS-0.7-just-after-the-XS-has-been-installed (i.e., the
XS-ejabberd's snapshot just before xs-setup example.org is run).


Anyways, thanks a ton !!!





 Jerry

Re: [Server-devel] Re-register an XO on XS schoolserver

Hi Vanessa.


Does the following help ?

a)
gconftool-2 --set /desktop/sugar/show_register --type bool True

b)
Reboot.


Now the Register option should be available via right-click.

XO-hang on 1.75-touch

[Ajay Garg]

Hi all.

Testing http://build.laptop.org/13.1.0/os14/xo-1.75/31014o2.zd on a XO-1.75
touch, I note the following ::


a)
After the image is flashed, the XO works fine in general; more importantly,
as long as all the work is being done via touchpad-pointer (and not through
finger-touches), things work perfect.


b)
Working through finger-touches also work well, as long as c) does not
happen.


c)
At some RANDOM point in time, doing Finger-touch on Home-View XO-icon ==
Finger-touch on My-Settings causes the settings-window to NOT open.
Thereafter, all clicks (via finger-touch, and touchpad-window) stop
working.


Anybody hit by this spuriously? (I am being hit fairly regularly, to the
extent of having the XO-1.75-touch unusable).

Re: [Sugar-devel] XO-hang on 1.75-touch

[Ajay Garg]

Thanks Jerry.

1)
I suspected that power-management could be   an issue.
However, the issue  occurs irrespective of whether power-management  is
enabled or not.

2)
I just realized that build-15 is also out, and there are some
log-differences (at least in shell.log).
So, better to download  os15 image,  and update with the tracing results
on os15.

WIll do that, and update accordingly.

 Ajay,

 I can't recreate this, but your log does look a bit strange, there is no
 dcon feedback noted.

 Can you edit /sbin/powerd and change line 454 from
 # tracing=1
 to
 tracing=1

 That will create /var/log/powerd.trace with the full cycle of events for
 powerd. Please reboot and see if you can recreate this issue, when the
 hang occurs include powerd.tracing along with the other logs you posted
 the previous time.

 Thanks

 Jerry

Re: Re: Re: [Sugar-devel] [TRANSIENT ISSUE] 3G-Modem not being recognised

[Ajay Garg]

Hi all.

*
I tested on XO-1.75 with os14; the frame appeared fine (booting-up with the
USB-flash drive, and USB-modem inserted) !!!

*
Pulling off my hair, I re-tested on XO-1.75 with os11 (booting-up with the
USB-flash drive, and USB-modem inserted) ; thankfully, the frame-icon did
not appear (as before).

*
I then tested on XO-1.75 with the os12 (booting up with the USB-flash
drive, and USB-modem inserted); the frame-icon appeared FINE here too.


I compared the packages-difference between os11 and os12; os12 has an
updated version of usb_modeswitch and usb_modeswitch_data. Also, in os12,
there is no more the error

usb_modeswitch_dispatcher: *** glibc detected ***
usb_modeswitch_dispatcher: double free or corruption (!prev):
0x00081fe0 ***

that was happening in os11 (in the culprit case, that is).


So, bad news   : Things are happening without us  knowing the root-cause :-\
 good news  : Seems like http://dev.laptop.org/ticket/12340 can  be
closed :D


Thanks everyone for the help (especially James).

 An icon will be added to the frame when a modem is connected, and the

 Also known as the GSM device palette.

 Since these mockups the icon has changed to a symbol for a mobile

Re: [Sugar-devel] [TRANSIENT ISSUE] 3G-Modem not being recognised

[Ajay Garg]

Hi all.

I tested on os11, with all power-management disabled.

0.
Insert a pen-drive.

a)
Inserted modem in another slot; the modem is detected.

b)
Reboot.

c)
Modem is NOT detected.

d)
Remove modem.

e)
Insert modem;  the modem is detected.


I tried the above steps 5 times; and the results were same.


Also, please find attached a sample  python script, which lists all the
detected network-devices.
When this script is run as python nm_test.py in step c), the modem-device
is not detected by this script as well; whereas in other cases, this
script  detects the device.









Another sequence ::


0.
Ensure that there is no pen-drive inserted in any of the USB slots.

a)
Inserted modem; the modem is detected.

b)
Reboot.

c)
Modem is detected.

d)
Remove modem.

e)
Insert modem;  the modem is detected.


I tried the above steps 5 times; and the results were same.

I will try the  same  steps with os12, once I am finished downloading it.

I don't have a XO-1.5; so can't try on it :-\

Re: [Sugar-devel] [TRANSIENT ISSUE] 3G-Modem not being recognised

I just compared the case_*_messages files, and it seems that the reason
of the modem not being listed/detected/appearing in case 1, is because the
cdc_ether driver doesn't start upon boot.

 Does a pen drive of a different manufacturer also cause the problem?

 (I see a similar problem on XO-4 B1 with 13.1.0 os12, ... if any pen
 drive is attached the modem is detected by the kernel, not shown by
 frame, and not shown by nmcli dev, but as I know the USB host has
 power design problems, I'm not sure how reliable this fact is.)

[TRANSIENT ISSUE] 3G-Modem not being recognised

[Ajay Garg]

Hi all.

I have been facing transient issues in getting the 3G-Modem recognised (via
the appearence of the corresponding icon in the bottom-tray).

There really is no fixed pattern; sometimes the icon appears when the modem
is inserted; sometimes not.
Same is the case when the XO is rebooted, while the modem is inserted. Upon
booting, sometimes the icon appears; sometimes not.

I don't remember such issues in 12.1.0; there, the icon appeared whenever
it ought to.


Is someone else too facing such transient issues; or am I the only one hit?

I understand that since as of  now, sugar-update-control has a dependency
over sugar, so the over-writing is done; but this does not seem the right
way.


Seems more like a design/architecture issue, rather than a problematic one
:D


Thanks again Jerry !!


 and the latest src rpm for sugar[1] and note the cp section of the spec
 file. Observe that sugar-update-control is present above while
 sugar-cp-control is absent. You can get the src rpm for
 sugar-update-control from OLPC[2].

Re: [POSSIBLY BROKEN FEATURE] Do 3G-Modem connections work in http://build.laptop.org/13.1.0/os5/xo-1.75/31005o2.zd ?

[Ajay Garg]

Well, I don't know what it is, but it's working now.

One point to note, is that I had to modify the code  FROM


#
  self._connection_timestamp = time.time() - \
 connection.get_settings('connection')['timestamp']

#


TO


#

  # Introspect the settings's keys once; else
sometimes

  # the key 'timestamp' gets missed.
  connection.get_settings('connection').keys()

  self._connection_timestamp = time.time() - \
 connection.get_settings('connection')['timestamp']

#

in sugar/extensions/deviceicon/network.py.



Sorry for the bother :-\

Query regarding bootfw.zip for upgrading-firmware on XO-1.75

Hi all.

As per http://wiki.laptop.org/go/Upgrading_firmware, we need the bootfw.zip
for upgrading firmware (for XO-1.75 too I guess).
However, when I look into the links (for eg.
http://dev.laptop.org/pub/firmware/q4d18/), I do not see any bootfw.zip.

Any ideas what I am doing wrong?

 Get it from the rpms that appear in rpmdropbox.laptop.org .


Thanks Martin, that was what was needed :)




 However,

  - it gets re-build by OOB when it is signed
  - the scheme is changing to have bootfw-number.zip to allow unified
 XO-1.75/XO-4 builds in the future

Full-Duplex-(Sound)-mode in XO-1.75

[Ajay Garg]

Hi all.

When I run

 arecord | aplay

on an XO-1, things work fine; I am able to hear back my own recorded sound
(as expected) :)



However, when I repeat the process on an XO-1.75, I do not hear back any
sound.

Music files (and other already recorded sounds) play well in general on the
XO-1.75.
It is only when the recording is done simultaneously, that the sound is not
heard.


Is it due to the lack of full-duplex-(sound)-mode in XO-1.75?
If yes, is there a plan to activate it? Or may be some other way to have it
working?


Will be grateful for any lights on this :)

 This is a current limitation of XO-1.75 audio drivers. We are working
 hard to address it.



Thanks Martin for the info.

Please keep me posted on the development regarding this.
I think it would be REALLY interesting to see the solution for this, as it
would provide a great insight into the differences between processor
architectures.

 Hi Ajay,

 please ansert cjb's question. It has a good chance of leading to your
 answer. What deps are you ignoring? Why --force?


 I am sorry I did not give the full info :(
 Usually, for development testing, I use this method,  as long as only
 sugar changes  are involved.

 When I first  came across the issue, I followed the normal way, and
 installed the sugar-control-frame and sugar-control-accessibility
 packages too (dependencies of sugar). I installed all the three packages
 without --force then.

 However, there came to be no difference in behaviour (as long as XO-boot
 was concerned). :(






 Also -- /var/log/olpc-dm* logs are likely to have important info.
 Please post them.



 Please find attached the entire /var/log/ directory, of the
 failed-to-launch-X-server boot on the XO-1.

 Note that the names of the files are capitalized and shortened - it so
 happened when I copied the var/log/ directory onto my pen-drive, from
 the shell login on the XO.


 Thanks and Regards,
 Ajay

Re: [Sugar-devel] Problems starting the XO

[Ajay Garg]

Thanks Chris and Mikus for the replies.

Well, I seem to have close down on the cause; but not close enough :(   The
solution is still not in sight.


I have been making some changes in the sugar-code, to have the Transfer to
Many feature working.
Things work fine on sugar-emulator; however, when I replace the files in
src/jarabe/journal folder on the XO, I fail to get the XO booting.


Now, the code is fairly big in amount; and it will take many days to
pin-point the issue (without any log info).
But one thing is sure, only when the files in src/jarabe/journal are
updated, does the XO fail to boot.


I tried one thing - I removed the directory /home/olpc/.sugar, and
rebooted, but the XO still failed to boot.
One thing I did notice, is that on reboot, the directory
/home/olpc/.sugar gets re-created, with the journal re-indexed info; but
unfortunately, there still is NO /home/olpc/.sugar/default/shell.log :(


So, answers to the following two queries will help in nailing the issue ::

   a)
   Is it possible to (temporarily) stop the
re-indexing of the journal on reboot?
   If yes, that could give some hints as to
if this is where the problem occurs.

   b)
   Better still, is it possible to have
shell.log created as the first file after the directory
/home/sugar/.sugar is created?



Any further help will be highly appreciated :)


Thanks and Regards,
Ajay

 I can't help you - but I've run into such a situation before.

 X (the display) is crashing - and is being automatically restarted, only
 to crash again (and again, and again. and ...).  I used to know how to stop
 these automatic restarts by commenting out something in /etc -- but things
 have changed an I don't know any longer.

 You being able to capture /var/log/messages implies that these automatic
 restarts were NOT interfering with you looking at the system.  [And it
 implies to me that you might manually patch kernel files to correct
 whatever is causing the crash.]


 What you did capture does not show the actual problem.  You will need to
 do additional looking - for instance, /var/log/Xorg.0.log  and
 /home/olpc/.sugar/default/**logs/shell.log  Perhaps capture 'dmesg'

Well, the code changes need to be tested on an XO first (as I said, that
things work fine on the sugar-emulator).
Only after the testing is passed on the XO, would the changes be comitted,
(fresh) rpms generated to the repos, which would then be pulled into the
image built from osbuilder.

If there is a way to pull the rpms directly into the image, I will  be more
than happy to do it. Please let me know if you have ideas regarding this :)




 Anyway, I got
 burnt building a test image with the latest DX3 rpms, you introduced a
 change in sugar that requires a newer version of sugar-toolkit but
 sugar's rpm Requires: are not set in to enforce a minimum version of
 sugar-toolkit.


Hmm.. my bad.
But

   * I guess sugar-toolkit (latest version) is also present in
the repos, which should have been pulled.

   * I think this is not the cause of the problem I am facing.

Hi all.

Under what circumstances, is the buddy-joined signal used; and in what

I ask this, because a simple grep on the activities-code-directories,

 The olpc released rpms may be a fork of the fedora code and a newer rpm

 where the files really live on the XO due to OOB's modifications to

 Think something maybe missing from your build environment, have you met

 undeclared BuildRequires, have you tried yum groupinstall devel*tools

yum groupinstall devel*tools proved to be enough !!

glibc-devel F14 package for armv5tel

[Ajay Garg]

Hi all.

I am trying to build avahi on my XO-1.75.

Building avahi requires glibc-devel as one of its dependent packages.

Very, very surprisingly, there is no glibc-devel present in the ARM repos
(for armv5tel/armv7tel) !!


I have tried building the glibc packages from the source-rpm, but even
that fails,  with no error message :\
Heck, building glibc packages fail even on x86 !!


So,
I would request everyone, if someone could point-me-to/give-me a
glibc-devel rpm for ARM, being used in the OLPC/sugar ecosystem, as I
believe that glibc-devel is a very fundamental package (or at least that
is what the glibc.spec file says).




For brevity,

a)
[olpc@xo-c5-b9-6c rpmbuild]$ rpm -qa | grep glibc

glibc-common-2.13-2.1.armv5tel
glibc-2.13-2.1.armv5tel




b)
[olpc@xo-c5-b9-6c rpmbuild]$ uname -a

Linux xo-c5-b9-6c.localdomain 3.0.19_xo1.75-20120321.1512.olpc.1398916 #1

Jon,

Doing sudo yum clean all, followed by sudo yum list glibc* has the same
result.

Also, all packages at

 Ok, that's a start.

  Reason is that, because avahi-daemon requires avahi-core to
 complete its
  linking process, whereas avahi-core would need avahi-daemon to
 complete
  its linking process (since the two values will be read from the
 context of
  avahi-daemon).
 
  That puts us in a catch-22 situation.

 Valid concern. I'd say do ask about that to the Avahi developers.

 My practical concern is that it may be tricky for your patch, as it is
 today, to land upstream. The sooner we hear from avahi devs, the
 better..

 So perhaps Telepathy-Salut should be told to contact its known nodes

Don't know if that would make a difference, because either ways, a machine
would send a (polling) signal to all the machines on the network, all of
which are known to it. That is, if there are N machines connected to a
(wifi) telepathy-salut network, each machine would be seeing the other N-1
machines; and each machine would be sending the (polling) signal to each of
the N-1 machines, be it in client-mode or server-mode.








 As they state, mDNS  DNS-SD are in use in fairly large networks with
 lots of nodes, so they have to be rather careful in not being too
 chatty.

 In our application of Telepathy/Salut, which in turn (mis?)uses
 mDNS/DNS-SD, we *know* that it only works passably with a small number
 of nodes,

so we are prepared to make it a bit chattier. It's only a
 shade more of chatty.


+1.
Especially more so, if we would be solving a major use-case :)

Patch written for Presence not updated, when client disconencts from telepathy-salut

[Ajay Garg]

Hi all.

I have written a patch for Avahi, that solves the bugs

[UPSTREAM] http://bugs.sugarlabs.org/ticket/3748
[DOWNSTREAM]   http://dev.laptop.org.au/issues/1332



###


For brevity, I am specifying the use-case ::

a)
XO-1 connects to telepathy-salut.

b)
XO-2 connects to telepathy-salut. Both XO-1,and XO-2, are able to see each
other in the neighborhood-view.

c)
XO-1 disconnects. XO-2 is now no more seen in XO-1's neighborhhod-view, BUT
XO-1 IS CONTINUED TO BE SEEN IN XO-2'S NEIGHBORHOOD-VIEW.


The expected behaviour is that XO-1 should also disappear from XO-2's
neighborhood-view after some time.


###


The upstream bug id is ::

https://bugs.freedesktop.org/process_bug.cgi


###


The patch is located at ::

http://people.sugarlabs.org/ajay/root/freedesktop_bug_51501/common-patch-for-f14-and-f17/customize-avahi-default-ttl-values.patch




For brevity, I am pasting the patch description


Please refer https://bugs.freedesktop.org/show_bug.cgi?id=51501

History ::
===

As pointed out by Simon McVittie in
https://bugs.freedesktop.org/show_bug.cgi?id=51501#c4,
https://tools.ietf.org/html/draft-cheshire-dnsext-multicastdns-15#section-10
suggests that the Time-To-Live (TT) of the mDNS record is likely to be
120 seconds.

However, for all purposes, in whatever testing I came across Avahi,
the TTL in effect was
75 minutes , which seemed a bit too late a notification of
buddy-going-disconnected.



Fix ::
==
Decrease the Time-To-Live (TTL).



Solution ::
===

Obviously, the easiest solution is to set the appropriate values in
  #define AVAHI_DEFAULT_TTL_HOST_NAME
  #define AVAHI_DEFAULT_TTL

However, this has the following caveats ::

(i)
It needs a re-compilation/re-packaging of avahi rpms, for every
change in the values. This is a major deployment headache.

(ii)
Also, there is no ideal TTL values.

The lesses the TTL values, more frequent multicast DNS packets will be exchanged
between a pair of peers, thus leading to more traffic.

However, too large a TTL value, would mean that the peer gets too late
a notification
of the buddy going disconnected.

Thus, ideal values can only be found out by testing in real-field.
This requires easy configuration of the TTL values, without needing to
re-compile the rpms.



Solution-Implementation ::
==

The cutomized TTL values will be read during avahi-daemon startup.

1.
AVAHI_DEFAULT_TTL_HOST_NAME will be set to the value, contained in the
file /etc/avahi/avahi-default-ttl-host-name.conf.

Default value is the same as before, i.e. 120 (seconds).


2.
AVAHI_DEFAULT_TTL will be set to the value, contained in the
file /etc/avahi/avahi-default-ttl.conf.

Default value is the same as before, i.e. 4500 (seconds), which is equal to
75 minutes.



How to customize ::
===

a)
sudo service avahi-daemon stop

b)
Change the values in the corresponding conf files.

c)
sudo service avahi-daemon start

Xavier Claessens xclae...@gmail.com


###


The pre-compiled RPMS (patched), both for F14 and F17, are available at ::

http://people.sugarlabs.org/ajay/root/freedesktop_bug_51501/platforms/f14/RPMS/
http://people.sugarlabs.org/ajay/root/freedesktop_bug_51501/platforms/f17/RPMS/


###


I have done the preliminary testings, and things seem to work as expected.
In particular, now the XO-2 disapplears from XO-1's neighborhood view,
after the number of seconds specified in the file
/etc/avahi/avahi-default-ttl.conf.


###



Kindly test and review the patch, as this solves a pretty important issue :)

Ajay

Re: Patch written for Presence not updated, when client disconencts from telepathy-salut

[Ajay Garg]

Hi Martin.

The patch link was embedded later into the email ::
http://people.sugarlabs.org/ajay/root/freedesktop_bug_51501/common-patch-for-f14-and-f17/customize-avahi-default-ttl-values.patch


Also, updating the tickets with the patch.. (sorry about not doing that
before..).


Also, the details are like this ::

a)
The patch is applied to Avahi, and the patched (avahi) rpms upgraded.

The (required 6) pre-compiled rpms are present at ::
http://people.sugarlabs.org/ajay/root/freedesktop_bug_51501/platforms/f14/RPMS/
http://people.sugarlabs.org/ajay/root/freedesktop_bug_51501/platforms/f17/RPMS/


b)
This patch IS responsible for adding two files to /etc/avahi ::

* /etc/avahi/avahi-default-ttl.conf
* /etc/avahi/avahi-default-ttl-host-name.conf


c)
As per the usecase, the XO-2 disapplears from XO-1's neighborhood view,
after the number of seconds specified in the file
/etc/avahi/avahi-default-ttl.conf.


d)
I was not able to any observable difference between the two #defines -
AVAH-DEFAULT-TTL, and AVAHI-DEFAULT-TTL-HOST-NAME.
So, for all purposes, they may be configured the same value (via the two
conf files).


e)
Actually specifying the values in the two conf files, would have to be done
at the OOB stage (as correctly identified by Martin).
A value of about 20 seconds (for each) would be good.



Thanks and Regards,
Ajay

 Thanks for working on this.

 Neither link has a patch. Where is the patch, as a text file?

 Reading the description, first you talk about a patch to avahi, but
 then you say it's configurable via files in /etc, so I'd expect a
 patch to OOB.

 If it is tweakable from telepathy or Sugar, then maybe a patch to
 Sugar, where it sets up the properties of the telepathy connection...?

 Ah, thanks! Have you shown this patch to Avahi hackers?



Just sent them a notification :)







 Avahi-daemon has /etc/avahi/avahi-daemon.conf, which is read by
 load_config_file() in main.c . Perhaps that is better than

 -#define AVAHI_DEFAULT_TTL_HOST_NAME (120)
 +#define AVAHI_DEFAULT_TTL_HOST_NAME get_avahi_default_ttl_host_name()



Bang on 

That was the first thing I had tried.

The #defines are needed in all the avahi-modules (avahi-core,
avahi-daemon, etc.), so it needs to have itself pre-processed from the
common avahi-common module. Thankfully, the two #defines are present in
avahi-common/defs.h.

This avahi-common is the basic common module, which is linked to other
modules (avahi-core, avahi-daemon, etc)

So far, so good.


But.. the problem starts now..

If the two additional values are read from the static int
load_config_file(DaemonConfig *c) method in avahi-daemon/main.c (via
/etc/avahi/avahi-daemon.conf), that does not work out.
Reason is that, because avahi-daemon requires avahi-core to complete
its linking process, whereas avahi-core would need avahi-daemon to
complete its linking process (since the two values will be read from the
context of avahi-daemon).

That puts us in a catch-22 situation.

So, actually, the right place to load the complete config is in
avahi-common module; but as of now, even in F17, the static int
load_config_file(DaemonConfig *c) method resides in the avahi-daemon
module :\

Anyways, I loaded the two required variables (without needing the methods
of avahi-daemon module) from the context of avahi-common.

 Ok, that's a start.

  Reason is that, because avahi-daemon requires avahi-core to complete
 its
  linking process, whereas avahi-core would need avahi-daemon to
 complete
  its linking process (since the two values will be read from the context
 of
  avahi-daemon).
 
  That puts us in a catch-22 situation.

 Valid concern. I'd say do ask about that to the Avahi developers.

 My practical concern is that it may be tricky for your patch, as it is
 today, to land upstream. The sooner we hear from avahi devs, the
 better..
