Do you want me to do more testing with the 4.3.2 version? -- Damien Cassou http://damiencassou.seasidehosting.st

[Pharo-project] Character and binary streams
by Michael Rueger Jan. 30, 2009

Jan. 30, 2009

Hi all, while working on the unicode cleanup I ran into the current implementation of Character>>storeBinaryOn: aStream "Store the receiver on a binary (file) stream" value < 256 ifTrue:[aStream basicNextPut: self] ifFalse:[Stream nextInt32Put: value]. Me thinks this is pretty useless, as there is no way to read the binary stream again unless you would know at which indices you stored one or four byte characters. The only place where this method is called from text converters writing to binary streams and can only happen, when the converter encounters a unicode character that has now corresponding mapping to the byte based extern character encoding (e.g. Latin1). So the question is what to do in that case? How do other systems deal with this problem? Michael

Running ScriptLoader loadOB fails at some point because it tries to load http://source.wiresong.ca/ob/OB-Enhancements-dr.291 instead of http://source.wiresong.ca/ob/OB-Enhancements-dr.291.mcz Adrian ___________________ http://www.adrian-lienhard.ch/

[Pharo-project] newDelta >0 failed in sqUnixMemory
by Damien Cassou Jan. 30, 2009

Jan. 30, 2009

Hi, with a recent stock pharo image and a new VM compiled from svn on Linux, I always get squeak: /tmp/squeak-svn/platforms/unix/vm/sqUnixMemory.c:172: uxGrowMemoryBy: Assertion `newDelta >= 0' failed. Aborted This does not happen on Squeak 3.9 nor 3.10. This did not happen yesterday when I was on Ubuntu Hardy. Now, I'm on Intrepid, GCC 4.3.2 and it crashes after 3 seconds of work on any Pharo image. You may want to know that to compile the vm, I was obliged to change sqUnixFBDevMousePS2.c to make use of the 'write(2)' return value because my compiler didn't want to compile if write(2) return value was unused. -- Damien Cassou http://damiencassou.seasidehosting.st

[Pharo-project] Updated Polymorph
by Gary Chambers Jan. 29, 2009

Jan. 29, 2009

Got annoyed with the PreferenceBrowser not fully tying in with themes so have reworked it a bit. Interesting to see that less code is needed when utilising the theme helper methods. Done as overrides for Squeak compatability, of course. Really need to start thinking of the base being Pharo with patches for Squeak though. Polymorph-Widgets-gvc.33 on SqueakSource. Regards, Gary.

[Pharo-project] why #ifNotNil: accepts parameter?
by Esteban Lorenzano Jan. 29, 2009

Jan. 29, 2009

Hi, I'm trying to understand why pharo modifies squeak behavior of ifNotNil: and introduces the optional parameter... is there a reason? Cheers, Esteban
