Following with my research, as you suggested, i checked the what parameters I'm passing at starting of squeak VM.

I executed "SmalltalkImage current extractParameters" on a XO (where Etoys is working fine and on a ClassMate with Ubuntu)

Te result are:

On XO: http://ubuntuone.com/1e1XxvDx6v41HUOyIDUoLS

On CM: http://ubuntuone.com/0NEk59zYasxeEL0sMlEjZs

As you can see, on CM (Ubuntu) the Dictionary has the key-value inverted.

I got an echo output from script etoys of classmate, as you can see bellow. Seems the passing argument is correct, right ?

ECHO OUTPUT:

exec squeak -encoding UTF-8 -vm-display-x11 -xshm -sugarBundleId org.vpri.EtoysActivity -sugarActivityId fb6717c7fece5e96de49f74ead6b01110228f086 -vm-sound-pulse /usr/share/etoys/etoys.image BUNDLE_PATH /usr/share/sugar/activities/Etoys.activity SQUEAKLETS /home/gustavo/.sugar/default/org.vpri.EtoysActivity/instance BUNDLE_ID org.vpri.EtoysActivity ACTIVITY_ID fb6717c7fece5e96de49f74ead6b01110228f086

For what reason the the key-values of Dictionary are inverted ?

Another thing, that could you me suggest to follow ?

Thanks in advance.

HI David,

You are right, the output of: "SmalltalkImage current extractParameters" is an empty Dictionary.

Many thanks for the clue, now i have to figure out, why the parameter passing isn't working.

Welcome Gustavo!

I am sorry, I haven't the bandwidth to try the versions you need, and I don't know the relevant classes deeply. Instead I had a quick look at Etoys 5.0 in Sugar 0.98 in Fedora 19. You may already have tried this:

Print

SugarLauncher new isRunningInSugar

That should be true. If it is false, the navigator flap will not show the journal buttons.

If it is false, then print

SmalltalkImage current extractParameters

It should be a dictionary that includes parameters set by the Sugar launch script. In the older version of Sugar I have here, they are ACTIVITY_ID, BUNDLE_ID, BUNDLE_PATH, SQUEAKLETS

If not, I would suggest a look at the python and shell scripts that launch Etoys.

Have fun! David

I am not sure. Please post the output of these shell commands:

which squeak

and

squeak -version

then let's hope someone with expertise in the Squeak VM (virtual machine) has some ideas.

Looks like it :-(. That implies theres a bug in the VM on ubuntu :-(. Might it be something to do with the vm-sound-pulse plugin mis-parsing the command line? What happens if you start it with no sound (omit -vm-sound-pulse) ?

After reading this thread, I was initially confused by the command line options that are being passed to the VM:

-encoding UTF-8 -vm-display-x11 -xshm -sugarBundleId org.vpri.EtoysActivity -sugarActivityId c03be0a816bee1440f701b7d3b504b0968cb3274 -vm-sound-pulse

These are options that are parsed by the VM executable itself, as opposed to being passed to the Etoys image and evaluated there.

I took a look at the VM sources, and see that the -sugarBundleId and the -sugarActivityId parameters will be interpreted by the VM executable if and only if the VM was compiled with Sugar support:

# if defined(SUGAR) else if (!strcmp(arg, "-sugarBundleId")) sugarBundleId= argv[1]; else if (!strcmp(arg, "-sugarActivityId")) sugarActivityId= argv[1]; # endif

I expect that if the Etoys image is run from a script that specifies those two VM parameters, and if the VM was not compiled without Sugar support, then the command line parameters are probably going to get out of whack. The dictionary that got turned inside out is probably a side effect of this.

So my guess is that the script is trying to run a VM for Etoys in the Sugar environment, but the VM that is being run by that script was not compiled with Sugar support enabled.

So if you're in /home/frank/squeak-ci/ and you say "$ target/cog.r2766/coglinux/bin/squeak target/TrunkImage.image HudsonTools.st", "HudsonTools.st" is translated into "/home/frank/squeak-ci/target/HudsonTools.st", not "/home/frank/squeak-ci/HudsonTools.st".

If you run the VM executable directly with the -help option, it will print a list of available command line options. If the VM was compiled with Sugar support, the list of X11 options will include this:

-sugarBundleId <id> set window property _SUGAR_BUNDLE_ID to <id> -sugarActivityId <id> set window property _SUGAR_ACTIVITY_ID to <id>

If the VM does not have this, then it will not handle the command line option parsing as expected.

As far as I can tell, the Sugar support in the VM is used only to set some X11 window properties. I am not familiar with Sugar, so I do not know why this is important, but I would expect that the basic functioning of Etoys and Squeak would not be affected by this at all. So just for purposes of testing, you might want to try running Etoys with the following two parameters removed from the command line:

-sugarBundleId org.vpri.EtoysActivity -sugarActivityId > 24c67ec800d1d71723f959b56a213accf140e7bc

I expect that if you run it this way, then Etoys should start up normally and the "inverted dictionary" problem will be resolved. This will at least confirm the problem, then we can figure out what to do to fix it.

Hi guys,

I had tried another approach, I installed "Etoys-To-Go 5.0.1.app" on my Ubuntu, and interaction with Sugar work, as you can see in the following screenshot (http://ubuntuone.com/1Ax7rU0ikfZHH1n0NClzKe) , i can open Journal, but another kind or error raised:

Any idea ?

Etoys-To-Go is packaged with a VM that is compiled with Sugar support. When you run the script to start Etoys in Etoys-To-Go, it uses that VM rather than any other VM that you might have installed separately on your Ubuntu system. That explains why the startup now works.

The error that you are seeing now is something else. There is some sort of failure occuring during the image startup. Class SugarLauncher is trying to do something in its startUp method (that is a method that is sent to various registered classes as image start time). It looks like it is trying to retrieve some image from dbus having to do with its "ownerBuddy" (whatever that is, I don't know). It apparently expects to get some sort of XML data from dbus, and it's not getting it for some reason.

I'm completely guessing, but this might be just something to do with starting your Etoys-To-Go directly from the command line, when perhaps the SugarLauncher was expecting that it was started in some other way. Sorry I don't know any more about this, but look for some kind of problem related to Etoys not being able to get this initial information from dbus.

If you run the VM executable directly with the -help option, it will print a list of available command line options. If the VM was compiled with Sugar support, the list of X11 options will include this:

-sugarBundleId <id> set window property _SUGAR_BUNDLE_ID to <id> -sugarActivityId <id> set window property _SUGAR_ACTIVITY_ID to <id>

If the VM does not have this, then it will not handle the command line option parsing as expected.

As far as I can tell, the Sugar support in the VM is used only to set some X11 window properties. I am not familiar with Sugar, so I do not know why this is important, but I would expect that the basic functioning of Etoys and Squeak would not be affected by this at all. So just for purposes of testing, you might want to try running Etoys with the following two parameters removed from the command line:

-sugarBundleId org.vpri.EtoysActivity -sugarActivityId > 24c67ec800d1d71723f959b56a213accf140e7bc

I expect that if you run it this way, then Etoys should start up normally and the "inverted dictionary" problem will be resolved. This will at least confirm the problem, then we can figure out what to do to fix it.

Hi Bert,

I modified the startup parameters, adding DOCUMENT and SQUEAKLETS, as you can see on the log file (http://ubuntuone.com/2ENSAyrV5UgSm8uHA1yQV1).

But exceptions still raiesd as you can see on printscreen: http://ubuntuone.com/7Zwub6TOv5A22HZeEQarsW

Also i checked the gconf configuration: and it is same as on XO where Etoys is working fine.

gustavo@ceibal-cm2:~$ gconftool-2 -R /desktop/sugar/user nick = estudiante-cm2 default_nick = system birth_timestamp = -663572121 color = #B20008,#FF8F00 background = /usr/share/backgrounds/ceibal/sugar.jpg

Something else to try ?

Thanks in advance.

Gustavo.

Hi guys,

I had tried another approach, I installed "Etoys-To-Go 5.0.1.app" on my Ubuntu, and interaction with Sugar work, as you can see in the following screenshot (http://ubuntuone.com/1Ax7rU0ikfZHH1n0NClzKe) , i can open Journal, but another kind or error raised:

Any idea ?

Etoys-To-Go is packaged with a VM that is compiled with Sugar support. When you run the script to start Etoys in Etoys-To-Go, it uses that VM rather than any other VM that you might have installed separately on your Ubuntu system. That explains why the startup now works.

The error that you are seeing now is something else. There is some sort

of

...

failure occuring during the image startup. Class SugarLauncher is trying to do something in its startUp method (that is a method that is sent to various registered classes as image start time). It looks like it is trying to retrieve some image from dbus having to do with its

"ownerBuddy"

...

(whatever that is, I don't know). It apparently expects to get some sort of XML data from dbus, and it's not getting it for some reason.

Almost. It's trying the "old way" of asking for the user name ("ownerBuddy") via DBus. This fails on newer Sugar versions, so in the error handler it then tries to use gconf to find the user name. It's reading .gconf/desktop/sugar/user/%gconf.xml and expects to find a "name" tag in it. Apparently that fails.

As for your startup problems, you appear to be missing an empty argument following the image argument. That is taken by Etoys as a "startup" document. After this empty argument there are additional arguments, like SQUEAKLETS etc.:

    ... /usr/share/etoys/etoys.image "" SQUEAKLETS ...

If you look at /usr/bin/etoys, it uses

    "$VM" -plugins "$BIN" $VMOPTIONS "$IMAGE" "$DOCUMENT" $IMOPTIONS

and "$DOCUMENT" is that startup document. It must be present, even if empty, if there are other image options following.

HTH,

• Bert -

I'm completely guessing, but this might be just something to do with starting your Etoys-To-Go directly from the command line, when perhaps

the

• Bert -

Finally I guess i have found where is the problem, following are the steps followed:

1) Install squeavm version 4.10.2

2) I learned how use the debug tools, as suggested Bert

3) I found the exception raise when %gconf.xml is read, by SugarLauncher -> ownerBuddy -> XMLDOMParser.

More precisely in the line:

<entry name="birth_timestamp" mtime="1389708044" type="int" value="-849347955"/>

If this line is modified as:

<entry name="birth_timestamp" mtime="1389708044" type="int"> <value>-849347955</value> </entry>

All work fine!

In a short:

I guess that XMLDOMParser doesn't support the xml line format: <entry name="birth_timestamp" mtime="1389708044" type="int" value="-849347955"/>.

I don't know much about xml format, but i think that is valid format entry, so XMLDOMParser has bug.

Fixing this gconf.xml parsing ETOYS works as charm in Sugar over Ubuntu.

Would be needed report this bug in another place to ask the fixing ?

Thanks.

Hi Bert,

I modified the startup parameters, adding DOCUMENT and SQUEAKLETS, as you can see on the log file (http://ubuntuone.com/2ENSAyrV5UgSm8uHA1yQV1).

You set the document to /home/gustavo/etoys but it needs to be an empty string.

But exceptions still raiesd as you can see on printscreen: http://ubuntuone.com/7Zwub6TOv5A22HZeEQarsW

It's probably trying to load "/home/gustavo/etoys" as a startup document, which fails.

Also i checked the gconf configuration: and it is same as on XO where Etoys is working fine.

gustavo@ceibal-cm2:~$ gconftool-2 -R /desktop/sugar/user nick = estudiante-cm2 default_nick = system birth_timestamp = -663572121 color = #B20008,#FF8F00 background = /usr/share/backgrounds/ceibal/sugar.jpg

I guess the Squeaklet directory is not found because of the argument mixup.

Something else to try ?

You could learn how to use the Squeak tools, like the debugger, so you know exactly what's going on ;)

Thanks in advance.

Hi guys,

I had tried another approach, I installed "Etoys-To-Go 5.0.1.app" on my Ubuntu, and interaction with Sugar work, as you can see in the

following

Any idea ?

Etoys-To-Go is packaged with a VM that is compiled with Sugar support. When you run the script to start Etoys in Etoys-To-Go, it uses that VM rather than any other VM that you might have installed separately on

your

Ubuntu system. That explains why the startup now works.

The error that you are seeing now is something else. There is some sort

of

failure occuring during the image startup. Class SugarLauncher is trying to do something in its startUp method (that is a method that is sent to various registered classes as image start time). It looks like it is trying to retrieve some image from dbus having to do with its

"ownerBuddy"

...

(whatever that is, I don't know). It apparently expects to get some sort of XML data from dbus, and it's not getting it for some reason.

Almost. It's trying the "old way" of asking for the user name ("ownerBuddy") via DBus. This fails on newer Sugar versions, so in the error handler it then tries to use gconf to find the user name. It's reading .gconf/desktop/sugar/user/%gconf.xml and expects to find a "name" tag in it. Apparently that fails.

As for your startup problems, you appear to be missing an empty argument following the image argument. That is taken by Etoys as a "startup" document. After this empty argument there are additional arguments, like SQUEAKLETS etc.:

    ... /usr/share/etoys/etoys.image "" SQUEAKLETS ...

If you look at /usr/bin/etoys, it uses

    "$VM" -plugins "$BIN" $VMOPTIONS "$IMAGE" "$DOCUMENT" $IMOPTIONS

and "$DOCUMENT" is that startup document. It must be present, even if empty, if there are other image options following.

HTH,

I'm completely guessing, but this might be just something to do with starting your Etoys-To-Go directly from the command line, when perhaps

the

If you run the VM executable directly with the -help option, it will print a list of available command line options. If the VM was compiled with Sugar support, the list of X11 options will include this:

-sugarBundleId <id> set window property _SUGAR_BUNDLE_ID to <id> -sugarActivityId <id> set window property _SUGAR_ACTIVITY_ID to <id>

If the VM does not have this, then it will not handle the command line option parsing as expected.

As far as I can tell, the Sugar support in the VM is used only to set some X11 window properties. I am not familiar with Sugar, so I do not know why this is important, but I would expect that the basic functioning of Etoys and Squeak would not be affected by this at all. So just for purposes of testing, you might want to try running Etoys with the following two parameters removed from the command line:

-sugarBundleId org.vpri.EtoysActivity -sugarActivityId > 24c67ec800d1d71723f959b56a213accf140e7bc

I expect that if you run it this way, then Etoys should start up normally and the "inverted dictionary" problem will be resolved. This will at least confirm the problem, then we can figure out what to do to fix

it.

Hi Georg,

The xml file content is:

I don't know much about xml format, but i think that is valid format entry, so XMLDOMParser has bug.

Whether the bug is in the parser or the file depends on the XML schema specified in the file.

Georg,

So if i understood well you, adding a schema specification to xml file, should resolve the problem ?

Thanks in advance.

Correct. And without a schema it is impossible to tell whether the file is valid or not.

Note however that

    <entry name="birth_timestamp" mtime="1389708044" type="int"

value="-849347955"/>

and

<entry name="birth_timestamp" mtime="1389708044" type="int"> <value>-849347955</value> </entry>

create different DOM structures: Once an "entry" element with a "value" attribute, then an "entry" element with a "value" child element. If the application expects the latter it will fail on the former.

Conclusion: the parser is ok, the document does not fit the requirements of the application.

Kind regards Georg

Sorry, my mistake I introduce a false clue, I thought the bug was on XMLDOMParser, but doing a more deeply analysis I guess that the problem is on the Class which call XMLDOMParser, more precisely on the method gconfPropertiesAt of SugarLauncher class, bellow paste the source code:

gconfPropertiesAt: aString | dir | "search up tree to guess home dir" dir := Project squeakletDirectory. [dir pathName = '/'] whileFalse: [ dir := dir containingDirectory. [FileStream readOnlyFileNamed: dir pathName, '/.gconf', aString, '/%gconf.xml' do: [:f | | props | props := Dictionary new. (XMLDOMParser parseDocumentFrom: f) tagsNamed: #entry do: [:entry | props at: (entry attributeAt: 'name') put: entry elements first contentString]. ^props]. ] on: FileDoesNotExistException do: [:ignore | ]. ]. ^self error: 'cannot find gconf path ', aString

Why i'm saying that XMLDOMParser isn't the problem, because i did the test, call XMLDOMParser passing the xml file and the parsing work fine:

f:=FileStream readOnlyFileNamed: /home/estudiante/.gconf/desktop/sugar/user/%gconf.xml'

XMLDOMParser parseDocumentFrom: f

Thoughts ?

Thanks in advance.

Not really. The schema would just define whether the file or the application code is in error. Essentially you have already resolved the problem by giving the file a structure the application can deal with. In any case AFAIK the XMLDOMParser is not part of the problem.

Hi Gustavo,

the problem is not in the XMLDomParser, but how it it used. Apparently the way gconf stores its values changed. Previously both numeric and string values had a separate entity inside, like you discovered. Now it appears int values are stored in a more compact way.

The problem is in the SugarLauncher>>gconfPropertiesAt: method. It treats strings and int properties the same way.

Instead of "entry elements first contentString" it might use "entry attributeAt: 'value' ifAbsent: [entry elements first contentString]". This should work with both the old and the new format. Here's the full method, patched (but untested):

gconfPropertiesAt: aString | dir | "search up tree to guess home dir" dir := Project squeakletDirectory. [dir pathName = '/'] whileFalse: [ dir := dir containingDirectory. [FileStream readOnlyFileNamed: dir pathName, '/.gconf', aString, '/%gconf.xml' do: [:f | | props | props := Dictionary new.

This document describes how to publish a fix for Etoys:

http://etoys.squeak.org/svn/trunk/Documentation/Developer-HowTo.txt

If you just want to fix it in the distro rather than waiting for an upstream release, you should be able to change the method, enter the hidden unnamed top-level project, and save the image from that project (it is important to be in that project when saving the image).

I saw the commit to fix the sugar interaction was done.

To generate the deb package of Etoys with the last changes, without wait for the upsream release: It is right the following procedure ?:

1. Run Etoys, and from unnamed project, update from server code.
2. Save the changes
3. Copy etoys.image and etoys.changes to my source code tree
4. Generate the deb package.

My doubt, is meanly if only etoys.image and etoys.changes are needed to copy ?

I don't know much about xml format, but seemingly it hasn't XML schema specification, right ?

I don't know much about xml format, but i think that is valid format entry, so XMLDOMParser has bug.

Whether the bug is in the parser or the file depends on the XML schema specified in the file.

Kind regards Georg

Karl: do you want to take a stab at doing an Etoys release? I don't have the time to actually do it, but I am willing to do some hand-holding :)

I will try. Must read up on this stuff, because it is easy to mess up.

I think I will start by collecting the changes since last release.

Hand holding and maybe some help with passwords is needed. I have changed computers a few times and I'm not sure I the subversion password.

Cheers, Karl

Bert,

I saw the commit to fix the sugar interaction was done.

To generate the deb package of Etoys with the last changes, without wait for the upsream release: It is right the following procedure ?:

1. Run Etoys, and from unnamed project, update from server code.
2. Save the changes
3. Copy etoys.image and etoys.changes to my source code tree
4. Generate the deb package.

My doubt, is meanly if only etoys.image and etoys.changes are needed to copy ?

Thanks. Gustavo.

Thanks. Gustavo

Hi Gustavo,

the problem is not in the XMLDomParser, but how it it used. Apparently the way gconf stores its values changed. Previously both numeric and string values had a separate entity inside, like you discovered. Now it appears int values are stored in a more compact way.

The problem is in the SugarLauncher>>gconfPropertiesAt: method. It treats strings and int properties the same way.

Instead of "entry elements first contentString" it might use "entry attributeAt: 'value' ifAbsent: [entry elements first contentString]". This should work with both the old and the new format. Here's the full method, patched (but untested):

gconfPropertiesAt: aString | dir | "search up tree to guess home dir" dir := Project squeakletDirectory. [dir pathName = '/'] whileFalse: [ dir := dir containingDirectory. [FileStream readOnlyFileNamed: dir pathName, '/.gconf', aString, '/%gconf.xml' do: [:f | | props | props := Dictionary new. (XMLDOMParser parseDocumentFrom: f) tagsNamed: #entry do: [:entry | props at: (entry attributeAt: 'name') put: (entry attributeAt: 'value' ifAbsent: [entry elements first contentString])]. ^props]. ] on: FileDoesNotExistException do: [:ignore | ]. ]. ^self error: 'cannot find gconf path ', aString

This document describes how to publish a fix for Etoys:

http://etoys.squeak.org/svn/trunk/Documentation/Developer-HowTo.txt

If you just want to fix it in the distro rather than waiting for an upstream release, you should be able to change the method, enter the hidden unnamed top-level project, and save the image from that project (it is important to be in that project when saving the image).

that should work, yes.

What name would you give your patched release?

This may be a red herring, Gustavo, but the squeakvm your used in Ubuntu is about a year and a half older than the one in Fedora (and so in your XO), which is 4.10.2-2614

It may be worth trying the current VM in Ubuntu.

Apparently it is available in 'raring ringtail'

http://packages.ubuntu.com/search?suite=saucy&arch=any&searchon=name...

You probably know the upstream site for the VM is

http://squeakvm.org/unix/

Have fun! David

Hi David,

You are right, squeakvm on Ubuntu is older than sueaqvm on Fedora 17, but on Ubuntu on the same machine (linux box) , i can run Scratch interacting well with Sugar. From Scratch I can save project on Journal.

PID TTY STAT TIME COMMAND 2058 ? S 0:07 /usr/lib/squeak/4.4.7-2357/squeakvm -vm-display-X11 -swapbtn -encoding UTF-8 -vm-sound-ALSA -sugarBundleId edu.mit.media.ScratchActivity -sugarActivityId 14b6c8252fd00670b2f668145b1b75ad4ccb205c ScratchXO.image

Any way i'm going to install squeakvm 4.10 version on my Ubuntu and see.

Thanks in advance. Gustavo.

Sorry - that is not correct.

I meant that that the current VM is in Ubuntu 13.10 'saucy salamander' (more recent)
