Hi,

Thanks for the info. The format that Charlie, et al are creating would supersede the format shown on the "Testing" page. This is still a "work in progress".

== XO experiments ==

=== PDFs in Browse===
Trying to view PDFs in the browser without the horrible download-journal-start Read dance. evince isn't going to make a plugin [http://bugzilla.gnome.org/show_bug.cgi?id=168933], they recommend [http://mozplugger.mozdev.org/ mozplugger]. I tried <tt>yum install mozplugger</tt>, it installed sox and gsm WHY??!, still no luck and maybe it messed up PDF download, I now get a Mozilla "rainbow-daemon" dialog not a nice Sugar dialog.

Maybe I need to install evince as well, since <tt>/etc/mozpluggerrc</tt> wants to start this? XO has evince library, but <tt>yum install evince</tt> pulls in literally dozens of other libraries so I cancelled.

== Wiki experiments and such ==

=== Activity list ===
Here's a way to extract info from an Activity group HTML file, assuming it's ruthlessly consistent:
curl http://wiki.laptop.org/go/Activities/G1G1/8.2 > Activities_G1G1_8.2.html
perl -ne 'chomp; next if m/Image:/; print if s:^.*?Download.*?href="(.*?)/([^/].*?)".*activity-version.*?(\d+).*$:[$1/$2 download $2]\t$3\n:; print if s:^.*/go/(.*?)".*:$1\t:' < Activities_G1G1_8.2.html > Activities_G1G1_8.2.lst3
clean up...

Gives [[/G1G1 8.2 HTML contents]]


for url in $(wget -q -O- http://wiki.laptop.org/go/Activities/G1G1/8.2|sed "s/>/>\n/g"|grep -v "^$"|grep "\.xo"|cut -d\" -f2); do
prog_ver=$(basename $url|cut -d\. -f1)
ver=$(echo $prog_ver|rev|cut -d- -f1|rev)
prog=$(echo $prog_ver|rev|cut -d- -f2-|rev)
echo $prog $ver $url;

=== Create a meeting ===
[[User:Mchua]] wants want to create new pages containing
<nowiki>[[Category:Test group meetings]]
[[Start date::2008-MM-DD HH:00]]</nowiki>

Try
[[User:Sj]]'s form to create a page that uses preload and such to prefill a page. Seems to work. The time is tricky, I'm not sure timezones are supported.

<inputbox>
type=create
preload=Template:New test group meeting
buttonlabel=Create a new page for a Test group meeting
default=Testing meetings/{{CURRENTYEAR}}-{{CURRENTMONTH}}-{{CURRENTDAY}}
width=40

=== XO Korea mystery ===
The gargantuan over-complex XO Korea structure from [[User:Php5]] means searching ''in English'' finds Korean pages, such as:
* [[XO_Korea/hobby_and_profession/business_area]]
* [[XO_Korea/business_content/45120000_Photographic_or_filming_or_video_equipment]]


How many pages in [[:Category:XO Korea]]?

{{#ask:
[[Category: XO Korea]]
|format=count
}}

: I sort of love php5's overcomplex microcosm, though :) and these days it's down to 10% of the whole... it reminds me of the bulk import of chinese characters and their meanings into an en-language dictionary, which overwhelmed /that/ random-page feature for a couple of years. --[[User:Sj|Sj]]&nbsp;[[User talk:Sj|<font style="color:#f70; font-size:70%">talk</font>]]

=== Damn transclusion woes ===
A bunch of pages were transcluding [[Friends in testing/current image number]], like
[[Template:Joyride-jffs2-link]]. Francesca (?) put a semantic annotation in there, which added it to hundreds of pages.

I hid that in a noinclude, but for some reason that messed up pages.

Let's try it here with a local copy in [[User:Skierpage/current image number]], transcluded into this link:

[http://xs-dev.laptop.org/~cscott/xo-1/streams/joyride/build{{User:Skierpage/current image number}}/devel_jffs2/ joyride-{{User:Skierpage/current image number}}]

== Testing my XO ==
Responding to the [[Friends in testing]] call...

=== clean-install of 650 back to the future ===
To see how olpc-update works from candidate-765, I ran [[Clean-install procedure]] to get os650.zip and fs.zip on a USB flash drive.

First Erasing, bunch of black squares,
then Writing, bunch of green then yellow dots.
A few red ones.

then a restart, then Ship.1 build 650 Christmas 2007 baby!

No sudo, had to [[su -l]]
but then
olpc-update candidate-765
more or less worked. irsync_pristine and irsync_dirty failed, but No out-of-memory.


During first boot,
error about no /home/olpc/.ssh
error about chmod u+rw something something not valid.
No ~olpc/Activities

Software updates "Checking for updates" "Loading groups... took forever, part of progress bar blanked out. <trac>8681</trac> ?

I looked in journal, and there were two entries, "pi Seconds ago" and "oi 24 minutes ago", with a _-_- document logo. (I had just changed my timezone, maybe the time was off.)

=== Problems updating to 765 ===
Mail "Signed candidate-765 and gg-765-2 builds available for testing" went out. I renamed my developer.sig key and tried
sudo olpc-update 8.2-765
but that build isn't signed so update complained so I killed it.

So I tried
sudo olpc-update candidate-765
that completed, suspiciously quickly.

But now my XO won't boot
Q2E1`8 Q2E
Trying nand:\boot\runos.zip
OS found - No signature for our key
Boot failed :-(

If I press the [o] key to boot the alternate image (which is presumably my previous unsigned build), I get the same error.

==== Solved by putting developer key on USB flash drive ====
I solved this problem by copying my backup of <tt>develop.sig</tt> to <tt>/security/develop.sig</tt> on a USB flash drive. With the USB flash drive inserted, booting from unsigned nand code worked.

Then I re-ran
sudo olpc-update candidate-765
and it worked fine.

=== Damn U3 technology f***s up USB drives ===
If you buy a USB flash drive, it probably has crappy invasive U3 technology. Even if you have autorun turned off, Windows' "helpful" USB driver auto-install will automatically install some stupid driver that presents the flash drive as both a removable drive and a CD-ROM. '''WTF!??!'''

So download and run http://www.sandisk.com/Assets/u3/launchpadremoval.exe , then open Device Manager and make sure you don't have a second CD-ROM.


=== Paint-23 on 8.2-763 ===
(I sent this to devel list.

Paint-23 on 8.2-763.
These are roughly in menu order.

If from Journal I double-click on a Paint activity icon, I get two icons in the Frame, one of which has a doubled menu ("Paint Activity - Resume - Stop - Resume - Stop") that I can't resume or stop. When I tried to reproduce I got two icons, the first had the doubled menu, but this time the second icon pulsed forever.


You can't name a paint session in Paint (6220, I added this to release notes).

I can copy Paint's marquee selection and it appears in the frame, but the selection seems inactive -- it's gray, has no hover menu, I can't drag it.

I couldn't get paste of a selection to work.

The Paint fill is so slow that I assumed the app had died.

The Tools menu looks like a tools palette but you it doesn't show the selected tool. Actually, there is one item that looks like a selected tool, but it's the rounded-rect around the current color.

The color selection swatches would be a lot more obvious if they started out as the kid's XO colors instead of black and black.

Meanwhile the T in the text menu does have a gray background as if it's selected, but it isn't until you click it. And the two effects icons have a white background as if they're active.

If you type a pencil or brush size in their drop-down menus you can't dismiss the menu from the keyboard.

The Pencil size seems unchanged after changing its size.

Polygon tool cursor doesn't look like the polygon tool icon.

The Shapes menu doesn't fit the available space, "Triangle" is in a more items drop-down. I would get rid of the "Line" shape so the Shapes menu can fit on the regular screen.

The menu is "Text", its menu item is "Type". What's the difference?

The image resize spinboxes are so slow if I paste a previous Paint image in, I assumed the app had died. If I type in the image resize text boxes nothing happens but I don't know if it's really slow or they're dead to text input. Ideally they'd immediately show the value you type in or spin to but then you'd get a busy cursor.

I can choose anything from the Journal for Image insert, e.g. a terminal session, but nothing happens if it isn't a previous Paint session. Is Paint meant to insert the preview image of non-Paint sessions?

After unsuccessfully changing the size of an inserted image, the pencil tool works but the paint tool gets stuck as a selection marquee tool (makes no sense, but it's happened three times to me).

The two Effects operations are next to each other and have similar icons but do completely different things. It would be better to separate them, and change the hover text for the first to "Make picture gray"

=== Notes on Software update of activities ===
Running 8.2-759, Software update offers me
* Distance 12 to 13,
* Firefox 4 to 6
* Measure 17 to 19
* Paint 20 to 22
* Pippy 25 to 26
Modify activity groups is empty. Is it still going to [[Activities/Joyride]] ?
That page has CC Licensing Activity and Scratch, yet Software update doesn't offer them.

I ran update and screen went blank and machine restarted. After restart, got new list of offered activities.

Looking at an activity like [[Cobble]], it has two repeating forms each with:
* URL for the .xo bundle:
* Version number:
* Releases tested on: 7.1.0 (650) 7.1.1 (653) 7.1.2 (656) 8.1.0 (703) 8.1.1 (708) Candidate
* Development status:

That's bad, because this info is tied to the page, it isn't associated with each other. Same issue as multiple test results.

Can we have many-valued property Works_on: "version (build)", thus "26 (Candidate)", "24 (8.1.0)" But need URL in there as well...
So I guess we need subpages with version support for each stream.

=== Notes on Update from 8.2-759 to 8.2-760 ===
sudo olpc-update 8.2-760
in [[Terminal Activity]] worked great! irsync pristine worked, verification worked.

After restart I got messages about writing NAND. It seemed that the reboot didn't tell me it was installing new firmware version Q2E17.

2nd restart displayed Q2E17, then booted into Sugar.

Got prompt to run Software update, but that reported "Could not access the network". I often get this problem.

'''bug?:''' With Software update panel up, I can't get to frame with mouse, but pressing the upper-right Frame key will show the frame, though it seems inactive.

The Frame showed an AP so I retried and it worked fine.


=== Display pulses after standby (Out-of-memory?) ===
Twice with 8.2-759 my XO had trouble displaying screen after being in "standby", the screen flashed on every 30 seconds. See [[User:Skierpage/out-of-memory]] for notes.

I sent e-mail ''XO screen pulses after "standby", OOM afterwards'' to devel@laptop.org and filed <trac>8490</trac>

People think its CPU pressure not OOM. Alas, there's no guide of helpful stuff to type in low memory.

=== Notes on Update from 8.2-757 to 8.2-759 ===
<tt>sudo olpc-update 8.2-759</tt> gave me the same <tt> Contents manifest failure at line 383 Last file examined: localtime</tt> error (<trac>8190</trac>.
and the same (?) out of memory error <trac>5954</trac>).

Supposedly these are fixed in build 8.2-758, so I shouldn't experience them any more.

I think this is known. By clicking power off and back on (i.e. not forcing a power off) it advanced to

and then a reboot with the new firmware. Linux boot had same-ish errors as before: a couple of

=== Notes on Update from joyride-2301 to 8.2-757===
I got the same <tt> Contents manifest failure at line 383 Last file examined: localtime</tt> error, so filed <trac>8190</trac>.
I got the same (?) out of memory error <trac>5954</trac>

Got a few hangs and instabilities.

=== Notes on Update from joyride-2230 to joyride-227<del>1</del>3===
Tried this, a later release than 2263 recommended by [[Friends in testing]].

==== Trac 5954 crashes ====

So I did it in a [[Console]], and joyride-2273 installed fine. Some errorsl

Note the crash in irsync dirty update, that was killing, not just sudo olpc-update, but the Terminal activity.

This sounds like <trac>5954</trac> oom-killer during olpc-update.

==== Various ====

Terminal Activity mouse jumped to Activity, but then just the text "Activity" got stuck in the top right corner. if I brought up frame, it was still there, I couldn't choose a menu item of one of my running activities. Clicking other items in the frame, like network or speaker, would just highlight Activity.

I did Ctrl+Alt+Erase to restart X and Sugar.

Read of a PDF works, but Sugar activity handbook shouldn't be a PDF <trac>7898</trac> and I ran into "Keep error on exit" <trac>7843</trac>, I pasted my Read log error for the latter.

Read of a 4-page DjVu file shows 1/4, lets me advance, but doesn't show anything. When I page backwards it gets slow, then really slow, then cursor won't track and the machine is completely unresponsive. Had to power cycle. Nothing obvious in the error logs.

But then I tried again on another DjVu file from http://djvu.org/docs/, http://djvu.org/docs/1998_zcoder.djvu. All blank, showed 1 of 10. Then I zoomed out and saw the text of page 1!! But when I zoomed in, Read died, and Browse too!. Nothing in error log. I updated <trac>6223</trac>.

I couldn't find any help on the wiki in Support FAQ, searching for "freeze", etc. for what to do when the machine goes unresponsive.

=== Notes on Update from build 708 (8.1.2 candidate) to joyride-2230 ===
Got a developer key, found a few bugs.

In 8.1.1, build 708, more /etc/issue shows
OLPC build update.1 708 (stream udpate.1; variant devel_jffs2)
Kernel \r on an \m

Bug: last line seems bogus!?

Couldn't
sudo olpc-update 709
got "unknown moudle 'build-709': could not find build 709: are you sure it exists?
Sure enough, <tt>rsync rsync://updates.laptop.org | sort</tt> doesn't list it.

OK, so much for trying [[8.1.2]]!

Per [[Friends in Testing]],
sudo olpc-update joyride-2230

seems to work.

Are the first two failures expected? Seems like rsync will fail if it goes into standby? ffm|sh on chat says this is all expected.

Note this update involves new firmware.

I pressed the check key to see information, below I type some of what I saw.
I can't keep up with the text.

=== Bugs, TODO ===

erased Log activity. No feedback after clicking [Erase] in confirm dialog. Still showed in Home view. If I clicked to start, I got endless pulsing icon.

Browse activity did go away when I erased it, as expected. (?)

Started Log after I'd erased it, it pulsed for a long time, then I had two Log activities on the Home view, one orange. ?!
<br />
<tt>shell.log</tt> had errors 'No such file or directory' from execute_child from HomeBox.py

<del><tt>'''cat /etc/issue'''</tt>
has a garbled second line: <tt>Kernel \r on an \m</tt></del>
<br />
Not a bug, /etc/issue is a template that gets filled in on new terminal.

<trac>7828</trac>In [[Home view]] , hovering on an activity brings up {name of activity} with an Erase menu item.
But in the journal, the default for each "session document" is "Write Activity", "Terminal Activity", etc. and those also have an Erase menu item.
One of those removes the activity's code, one just removes a "session document". I get them confused.

<trac>7830</trac> The submit button in the DevKey form file:///home/.devkey.html looks weird, "stripey"

<trac>7831</trac> The Journal menu for Stopwatch activity installed from OLPC library is too wide to fit screen.
