Web sockets in Zinc

by Andy Burnett

Does Zinc support the web socket protocol? Or, is it likely to in the near future? Cheers Andy

Hi. I don't have time right now to check your code, but just to let you know another implementation of BTree that you can look at: http://www.squeaksource.com/BTree On Sat, Aug 13, 2011 at 3:59 PM, StÃ©phane Ducasse <stephane.ducasse(a)inria.fr > wrote: > > On Aug 13, 2011, at 3:56 PM, Jonathan Kelly wrote: > > > Hi, > > > > well, I think I'm starting to get the object thing.

First Steps

by Jonathan Kelly

Hi, well, I think I'm starting to get the object thing. I coded up the beginnings of a BTree package .. and I think I'm sold on Smalltalk - I really love the debugger!! If anyone has 5 minutes to kill having a look and give some feedback, I'd appreciate it. It's in squeaksource - I think I set it up so anyone can see it ... let me know if it isn't (and how to make it visible too! :) It only has an add function so far (and the page search is only linear - I'll get to that). useage x := BTree withOrder: 2. x add: 11.

Re: [Pharo-users] MAConditionError opens a debugger

by laurent laffont

Romain I've looked at it. The problem is that SeasideHosting (thus SmallHarbour :) is rather old and Magritte seems to be used in an obsolete way. So the MAConditionError is not catch anymore by (removed in Seaside 3) MAValidationDecoration>>processChildCallbacks: So I put an ugly hack in SHLoginComponent waiting for rewriting it the right way (but not now too tired).

I used the following script (about 2 months ago I think ) in Pharo 1.3 "SqueakDBX" Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfSqueakDBX'; load. ConfigurationOfSqueakDBX project latestVersion load. "GLORP" Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfGlorpDBX'; load. ConfigurationOfGlorpDBX project latestVersion load. II use DBXTestCase for my test with the code I send in my email (is it ok for you?), but I will have alook at DBXQueryTest too. No problem to put it in the test suite - it makes me remember that I still didn't send my license agreement to Stephane but I will do it asap...

First of all, thanks for poiting out the bug. Now, Guille asked you how did you install SqueakDBX/GlorpDBX because we are VERY near to release a new version of the new project called DBXTalk in which we will release a new version of SqueakDBX, which will be called OpenDBXDriver and a new release of GlorpDBX and Glorp, which we port the latest version from VW. You will have more news very soon, but I recommend you to migrate to this new stuff once it is out. > > | settings dbc stmt resultSet coll | > settings := DBXConnectionSettings > host: SmalltalkImage current imagePath, '/' > port: '' > database: 'testdb.dat' > userName: '' > userPassword: ''. > dbc := DBXConnection platform: DBXSqlitePlatform new settings: settings. > [ > dbc connect. > dbc open. > dbc execute: 'drop table if exists foo'. > dbc execute: 'create table foo (id int not null, name varchar(64) null )'. > dbc execute: 'insert into foo values(1, null )'. > dbc execute: 'insert into foo values(2, ''riptobe'' )'. > resultSet := dbc execute: 'SELECT * FROM foo'. > coll := OrderedCollection new. > "error here for null value in second row" > resultSet rows do: [ :r | coll add: r values ]. > coll inspect. > ] ensure: [ dbc close ]. > > I am out of time right now, but I would love if you or someone can take this piece of code and "adapt it" as a regular SqueakDBX test. If you do this, please do it directly in the package OpenDBXDriverTests of the repo http://www.squeaksource.com/DBXTalk. We really welcome your test :) You can add it to: DBXQueryTest.
