Re: 3.10 image hang

Hello Jerome:

Thanks for the notes on the bug report. I will prepare a report and post it.

I downloaded the basic image from squeak.org/download. I did not know how to figure out whether the image has Block Closures so I did this:

#(a b c) do: [ :s | Transcript show: s] ......... and got "abc" in the transcript.

and this...

#(a b c) do: [:s | [Transcript show: s] fork] and got "c" in the Transcript (from an example from the mailing list)

So two questions:

1. Why should adding "fork" to the code change the closure behaviour

2. There are BlockClosure and BlockClosureTest classes in the image, does this qualify to be supporting full closure

Regards,

Hi Prashanth Hebbar,

It looks like you have found a fine bug (or two).

A good way to deal with it is to start a mantis report.
http://bugs.squeak.org/my_view_page.php
is a good place to start. You can get an account freely and easily.

Please remember that the first rule of troubleshooting is first hand information.

The clearest reports will start with a way to reproduce the problem.
You have given details of what system and image you are using.

The walkback is interesting. Now if you can also supply a recipe for getting to that walkback.

E.G. Starting with a fresh xxx image.
Do this
this and this
and the walk back happens.

Upload any files needed to reproduce the problem. It always helps if your example is boiled down to the simplest thing that will cause the error to occur.

In additional details or a note include the walk back.

The clearer you make the report, the easier it will be for someone to look into the problem.

Once the report is written its worth pointing to it on one of the lists. The squeak-dev list would probably reach people most interested in this level of problem.

Yours in curiosity and service, --Jerome Peace

The suspect are the recent changes from block contacts to block closures. I am curious when you refer to the basic image whether you are refering to one before the those changes?

Good luck with the report. --Jer

[ANN] STicky

2009-09-26T15:16:30Z

STicky is a pluggable real-time evaluator and/or translator workspace
aimed to learn languages. For a quick overview please take a look at
the presentation video: http://www.youtube.com/watch?v=b9uUIEaGyoU

The Smalltalk evaluator could be useful in learning courses or for
newbies typing expressions, but other translators/evaluators may help
with more advanced usage, it all depends of the source and target
languages you're using. Some default external translators, which does
the real job, were included :

Smalltalk to JavaScript (ST2JS by Diego Gomez Deck)
Smalltlak to Java (Smalltalk2Java by Alexandre Bergel)
Smalltalk to SQL (ROE by Avi Bryant)
Smalltalk to AST nodes (Marcus Denker et al)
HTML validator (Todd Blanchard)
JSON to Smalltalk (Tony Garnock-Jones et al)
(...contact me if you want to add your translator in the release, a
facility to automatic installation of translators is provided)

You can easily plug translators and the workspace will update the
current contents dynamically inside a sticky-like dialog or a fixed
pane, the updater interface was decoupled to make possible other kinds
of widgets too, but this is a bit experimental.
Downloads from:

http://www.squeaksource.com/STicky.html

Comments are welcome.

Hello Claus:

Some context and update:

The error is occurring when I try to save home project of image 3.10.2-7179 (Damien Cassou's web based image).

I have tried with VM versions 3.10.6 (2007) and 3.11.5 (Sep 2009).

I do not face this problem in the basic image from squeak.org.

Check help->vm statistics for total and free memory just before you save. If
it is indeed low, you could increase it using -memory option. E.g.
squeak -memory 80m

3.10 image hang

2009-09-25T22:31:20Z

Hi:

I am using Squeak 3.10 on a Windows XP (2 GB RAM, 2 Ghz, Intel) While trying to save a project, I got a DNU and the image hung. The Debug walkthrough showed the error in "isSystemDefined" method. On further examination, I found a LowSpaceDebug.txt in my default directory.

I had similar problems earlier both on XP and Vista. Image would freeze and the CPU usage would show 100%. That problem continues in my new machine which has Ubuntu.

I suspect that the image is entering an infinite loop. There is little or no documentation of this problem. I have been working on a 3.8 and 3.9 images for some time now.

I checked mantis and came across a fix for the TransformationMorph behavious which would solve the freeze problem but I don't see how it is relevant to what I am facing. I may be missing something obvious.

Can someone please help me.

Regards,

Re Database Support - ODBC

Thanks to everyone. Seems there are definitely some good options to look into and experiment with.

The ODBC option will be one I explore, I found the DBX option interesting as well seems to be alot of activity and
development occuring here http://wiki.squeak.org/squeak/6052

Thanks again Your input and ideas are greatly appreciated..

We do. Our servers rely on the ODBC package heavily; I can vouch for the
the unixODBC/MySQL combo.

Re: Database Support - ODBC

Hi.

There is an ODBC package for Squeak that I have been using
successfully for years, although not in heavy production environments
(http://www.squeaksource.com/ODBC). There is a new package,
SqueakDBX, that connects to many databases as well, including those
you listed, I believe. It apparently works well on most platforms,
although I have not used it yet
(http://www.squeaksource.com/SqueakDBX). In addition, there are
native drivers for Postgres (api v2 -
http://www.squeaksource.com/PostgresV2 with object to relational
mapping Glorp at http://www.squeaksource.com/Glorp), MySQL
(http://www.squeaksource.com/MySQL and various other packages on
Squeaksource).

Hi.

I don't know about SQL-based database support in Squeak. What is available and well-supported are (among other solutions) Magma and Gemstone. Magma is a Squeak-specific object storage thingie. GemStone is a heavy-weight commercial object database with a Squeak UI. Google them. They both store objects directly so you don't need to use SQL.

What you'll find lacking is the GUI. There is no really good table widget available and personally I find the state of the other widgets disappointing. A web-based app is your best bet for a nice looking GUI.

[ANN] Krestianstvo SDK - Smalltalk, Croquet, Seaside... programming on native spoken language (Russian)

2009-09-16T07:13:56Z

Hello!

Introducing Krestianstvo SDK.

Krestianstvo SDK is built on top of OpenCroquet SDK with preloaded packages (some of the list: Sophie XUL-CSS, Seaside, OMeta, and Krestianstvo itself).
From now it will be entirely native spoken language based (Russian).
The SDK is updated through change set's update stream and source code could be easily filed in/filed out containing unicode chars.
The current developing version of the Krestianstvo SDK could be downloaded here (one-click image for Windows, Mac OS X, Linux).

Здравствуйте!

Представляем вашему вниманию открытый проект Крестьянство SDK.
Наконец-то, стало возможным программирование в SmallTalk, Croquet, Seaside на родном языке (Русском).
Мы еще только в начале пути, но тем неменее уже доступен для скачивания базовый образ для основных платформ (Windows, Linux, Mac OS X).

Крестьянство SDK построен на основе OpenCroquet SDK с предустановленными пакетами (некоторые из списка: Sophie XUL-CSS, Seaside, OMeta и Крестьянство).
Отныне она будет разрабатываться полностью на родном языке (русский).
Крестьянство обновляется путем потока изменений и исходный код может быть легко (загружаться в/ выгружаться из) образа приложения.

Текущий вариант Крестьянство SDK можно загрузить здесь (однокликовый образ).

Recovering from a completely 'crashed' squeak image

2009-09-12T15:02:16Z

I ran the Update Software option on a new Seaside 2.8.4 one click image. After a long period of downloading and updating, I tried to save the image but got a DNU message about mouse overs. Anyway, in the end the image did save, but now when I restart Squeak I get a message saying "Squeak VM quit unexpectedly".

I am not particularly worried about recovering the contents of this specific image - I had only been playing with it - but given that I am sure this will happen again at some point in my development life cycle, I would like to know the basic approach to recovering a usable image. What would people recommend.

I am still trying to figure out how to use the package. I have this and hit an exception 'sayHello not found'. I checked my xmlrpc server and there is a function sayHello($args)

url _ Url absoluteFromText: 'http://myBlog.com/xmlrpc.php'.
proxy _ XMLRPCProxy new url: url.

r _ invokeMethod: 'sayHello' withArgs: #().

I am not sure as to the correct usage of the package. The closest thing I can think of to test the server is XMLRPCProxy >> invokeMethod. Am I doing it wrong?

Thanks,

Ching

Hello Ching,

I do not know the answer to your question, but I suggest that ask
on the squeak-dev list. There are more people on that list who have
experience with topics like this, and no one will mind if it is a
newbie question :)

Re: xmlrpc

2009-09-10T07:56:18Z

this sample code work fine for me (you can try it in a workspace)

url := Url absoluteFromText: 'http://xmlrpc-c.sourceforge.net/api/sample.php'.

proxy := XMLRPCProxy new url: url.

r := proxy invokeMethod: 'sample.sumAndDifference' withArgs: #(5 3).

the result r should be

a Dictionary('difference'->2 'sum'->8 )

beware with some proxy between you and the xmlrpc server, i had to disable my proxy (and restart squeak) for this example to work.

Cheers

Thanks everyone for the replies. I have not had a chance to try it yet, but it was one of the methods that I had come across but was not sure if it was the "best" one to use.

See String>linesDo: and its senders. For parsing a line into tokens, you can
use findTokens:

Searching source code is quite easy in Squeak. In this case, I used
(Alt+Shift+W) to bring up the message search tool and searched for "lines".
Then I used senders/implementers to explore methods.

I think that many of us have had experiences similar to this. It is
ironic but true, the more you "know" about computers and languages, the
harder it is to grok Smalltalk the first time. But it's certainly worth
the effort :)

String>>findTokens is your friend here.

And FileStream>>contentsOfEntireFile gets the whole file into a string
before you find the tokens. But I'd prefer to read the file one line
at a time into a collection of strings.
