Re: [Pharo-users] Voyage: Circular references

[Sabine Knöfel]

Hi Esteban,

yes, now the Rectangle Example works after doing the reset.

But saving my model still leads to a non responding image because
Voyage is trying to write json for all model stuf deep deep deep and
circular. Perhaps same like:
http://forum.world.st/Voyage-Circular-references-td4691940.html#a4699436

I dont know anything about Magritte (yet) and I need a hint what to
define in my model so that it stops creating json at certain points
and creates only e.g. a Symbol.

Example: My model instance  of trip has a connection to an instance of
country. The country should not be written in json with all its
definitions. Voyage should only write e.g. #germany in the json and
later, when getting the instance back from the database, I want to
reassign the trip to the country.

I already implemented this stuff when working witk Mongotalk the last
months and it worked fine. But my question yesterday:
http://forum.world.st/MongoDB-open-close-in-production-singleton-or-not-td4699322.html
lead to my impression that I should use voyage.

So, how can I define the "borders"?

Sabine

Re: [Pharo-users] Voyage: Circular references

[Bernat Romagosa]

Hi Sabine!

If you want an object to be referenced by another, and not embedded in it,
you need to give that object root entity. As a root, the object will have a
collection of its own, and will be referenced by other objects by id. If
the object is not root, it will be embedded inside the referring object as
a property.

So, to be safe, always set #isVoyageRoot to return true at class side of
all objects you don't want to have embedded. In general, "big enough"
objects who are referenced by different objects should be root.

In my case, I had a centre which had users which had centres. Users also
had projects, and projects also had users. Big mess, I know. Besides that,
all users, centres and projects had profiles. My solution was to make
centres, projects and users be roots, and let only the profiles be embedded.

I hope this helped!

Bernat.

Re: [Pharo-users] ZnHttpUnsucessful: 501 not implemented

Thank You Sven.
I've read so many tutorials about building a repository and they non of them 
talked about that. ( I don't know why I didn't think of referring to pharo by 
example...)
Thanks for the help :)
Much appreciated

Have you read about Monticello in the 'Pharo by Example' book ?

  http://pharobyexample.org/

First you have to create your repository online, then you save your package to 
it.

Maybe you could also read this

  http://zn.stfx.eu/zn/build-and-deploy-1st-webapp/#savingcodetoarepository

but the book is better, I think.

Re: [Pharo-users] SerialPlugin

[Bernat Romagosa]

Hi Ricardo,

By using exactly your same packages, it still didn't work on Linux. So I
guess I'm stuck with a proprietary system for the moment... :(

It seems to work on Mac, no compiling or tweaking needed, so I'll start
working on a Mac box for the moment, although I'm as productive on anything
but my PC as if coding with a typewriter...

I'll still keep looking at the Unix plugin code to see if I can fix it. I
think I've spotted something weird at:

if ((sp->spDescriptor= open(portName, O_RDWR | O_NONBLOCK | O_NOCTTY))
< 0) {
fprintf(stderr, "Error while opening the serial port (%s).\n",
portName);
return portOpenFailed(sp);
}


This fprintf prints:

Error while opening the serial port (/dev/ttyUSB0!).


Notice the last character inside the parens. Sometimes it's a $!, sometimes
it's a $9. This smells like we're reading one position more than needed
from the char array, but I've tried changing its size and, even when
portName has the right value, open() still returns -1...

 I kinda "fixed" it last year but since I didn't had any serial port
 stuff to test it, it was just in abstract (Luc was using it, thought)

 There was a report a couple of weeks ago to try using double slash.

 SerialPort new openPort: '/dev//ttyUSB0'

 What's wrong with SerialPort? The "cannot open port" error message is
 about as informative as "sorry, not gonna happen" :(

Hi Bernat,

I'm going on vacations tomorrow, but if you provide me a way to test the plugin 
(like for example doing a remote session ;) ), I promise to work on fix it as 
soon as I'm back (I'm going out just one week). 

can you locate some time for doing it?

 Still, having executed the script, I get yet another error, this

Hi Sabine, 

If Bernat help is not enough, I would like to have some more insight on your 
problem, so If you can put here a better description of your model and the 
problem you are having, I will have a look :)

Re: [Pharo-users] Voyage: Circular references

[Sabine Knöfel]

Hi Esteban,

thanks!

I think the solution of Bernat will not be enough for me.
I added the class methods isVoyageRoot to the root objects (like trip,
country and so on).

But I have instances which should never be persistent, e.g. the
country I mentioned. The Country has currencies and expense rates and
this is a lot of stuff...this should be only transient in the image.

The transient country is referenced by persistent instances of trip.
(countrie does naturally not point to trips)

Trip (persistant) -> Country (transient)

If I try to save a trip, voyage at some point enters
>>rawReference: description:
and there, it looks whether anObject (a country) isNew:
isNew means the other object, the country has an _id (mongo id).

The country does not have an id and for this reason, voyage tries to
make it persistent although its class has isVogageRoot false.
And than the system enters a point where it tries to make so many
objects persistent that the image does not respond anymore.

So, my question is: is it possible to define
"In class trip, there is an inst var country -> voyage please save
only a symbol here"
and
"voyage, if loading a trip, for inst var country, do shting"

Sure, I could save symbols within the trips country inst var all the time
and get the country it if needed, but it would be nicer if voyage coud
do that for me .-)

Re: [Pharo-users] Pharo 2.0 and Android

[jannik.laval]

Hi,

I am trying with Pharo2.0.
It seems to work but I have 2 errors:
- the vm seems old: I have a message that says the vm should be updated
- Unicode plugin seems not available. I have to change something in my code to 
not use it ?

That's great, even faster than bioPython, and thanks to Petit Parser.
That's great!

I hope it will be on good place on Pharo's web site...

Re: [Pharo-users] Pharo 2.0 and Android

[jannik.laval]

Ok,

I solved the problem of the Unicode plugin: I removed it :)
for the old vm, I don't know what is the impact, but it seems to work.

Phratch can be loaded on Android now, but it is really slow, i am checking that.

yes that is a known issue with low priority. Using a real browser, namely not 
IE, will solve the issue :)
