Update stream -> MC (was: Re: About a working group on CS->MC)
by danielv＠tx.technion.ac.il 22 Oct '04

22 Oct '04

Hi Stef. I agree. I've only now gotten around to actually trying UnstableSqueak, and after playing with it a bit I'll have more ideas on how far off we still are. Unless Avi objects or prefers to do it himself (being the expert), I'll probably create during the weekend an initial page on the Wiki describing the goals, current status, problems.

Vassili's Regex
by Torsten Bergmann 22 Oct '04

22 Oct '04

Hi, Thanks for the quick response. The description in RxParser(class) >>#c:syntax: for ^ was a little bit misleading here. Now I understand. >If you need to match the spaces (and tabs/newlines), try >' 1' matchesRegex: '[[:space:]]*[0-9]' The ST extension for unary messages is nice. Could this also be achieved without the syntax extension (for example in other languages RegEx packages)? I've seen that other packages (PHP) also support a {} notation for instance to check money amounts they use: ^([0-9]){1,3}(.[0-9]{3})*(,[0-9]{2})?$ Thx Torsten -- GMX ProMail mit bestem Virenschutz http://www.gmx.net/de/go/mail +++ Empfehlung der Redaktion +++ Internet Professionell 10/04 +++

Storing floats, etc in GOODS
by Yar Hwee Boon 22 Oct '04

22 Oct '04

Hi Storing floats, etc in GOODS, using Avi Bryant's client, numbers such as 3.2 are returned as 3.199999809265137. Seems that GOODS stores floats using the IEEE 32 bit format. How do you work around it? I'm storing money one in currency only. Create a currency class, maybe? Thanks. -- Regards HweeBoon MotionObj

Croquet on SqueakMap?
by David Faught 22 Oct '04

22 Oct '04

Are there any thoughts about adding a Croquet Jasmine release to the categories for SqueakMap? I'm a little unsure just how far the revolutionary versus evolutionary thinking of the Croquet team extends. __________________________________ Do you Yahoo!? Read only the mail you want - Yahoo!

I also ran into problems trying to reuse a connection for more than one query. It looks like the driver was designed that way although I have heard from others (Colin?) that it does work, maybe if the resultset is completely read in between. But my experience and observation is that connections are not serially reusable much less reentrant. But multiple concurrent connections are ok (if not elegant). >However after each query, the connection seems to close itself. Is it >the normal behavior or is it something wrong? My experience in writing the Persistence package for the Mysql driver is actually that care had to be taken to close them after use as the Mysql server sometimes had problems with more than 100 concurrent connections. > PS2: What is the most reliable driver & DB couple for Squeak? Is there a > 100% Squeak solution for DB ? If you want to stick with Mysql, have a look at the aforementioned Persistence package which maps Mysql into objects. It works around this single-query behavior of the driver. It's 100% squeak and it is seeing reliable production use. -- Alan

Re: [ENH] shiffmanTimeout-brp (version 2 [su][cd][sm][er])
by pinkney_b＠aircom.co.za 22 Oct '04

Hi, Here is my second attempt at the Schiffman timeout. Thanks for the reviews. On the advice of Mssrs Rollandin and Wirblat, the method has been renamed #valueWithin:onTimeout: The comments annotating my previous axamples have also been corrected. Frm the preamble... >From Squeak3.8alpha of 8 September 2004 [latest update: #6297]'! "Change Set: shiffmanTimeout-brp Date: 21 October 2004 Author: Brent Pinkney Implementation of #valueWithin:onTimeout:. This changeset reimplements Allan Schiffman's timeout mechanism for Squeak 3.8. Usage: [ 50000 factorial ] valueWithin: 1 second onTimeout: [ 666 ]. "Answers 666" [ 3 + 4 ] valueWithin: 1 second onTimeout: [ 666 ]. "Answers 7" Allan's implementation has been reworked to satisfy ANSI exception handling and the Duration class. Included in this changest are three new SUnit tests. ExceptionTests >> #testNoTimeout ExceptionTests >> #testTimeout ExceptionTests >> #testTimeoutWithZeroDuration This changest makes some minor changes to ExceptionTester to accomodate #testTimeout.

MySql connection
by Hilaire Fernandes 22 Oct '04

22 Oct '04

Hello, Exploring the use of the MySQL driver, I have found that each time I want to do a SQL query I need to create a new JdmConnection. I was believing that opening a JdmConnection then doing a set of queries will be all I needed. However after each query, the connection seems to close itself. Is it the normal behavior or is it something wrong? Thanks a lot. Hilaire PS1: Not sure if it is related but the MySql server and Squeak application are located in different location in the Internet. PS2: What is the most reliable driver & DB couple for Squeak? Is there a 100% Squeak solution for DB ?
