[VM] Windows VM SurfacePlugin.dll LoadLibrary failure
by Peter Uhnak April 1, 2017

April 1, 2017

Hi, recently (couple of days ago) sometimes when I start Pharo there's a box at the bottom "Debug console" with the following info ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ # Debug console # To close: F2 -> 'debug options' -> 'show output console' # To disable: F2 -> 'debug options' -> 'show console on errors' LoadLibrary(SurfacePlugin) (998: Invalid access to memory location. ) LoadLibrary(SurfacePlugin.dll) (998: Invalid access to memory location. ) LoadLibrary(SurfacePlugin) (998: Invalid access to memory location. ) LoadLibrary(SurfacePlugin.dll) (998: Invalid access to memory location. ) LoadLibrary(SurfacePlugin) (998: Invalid access to memory location. ) LoadLibrary(SurfacePlugin.dll) (998: Invalid access to memory location. ) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ I have Windows 10 & VM Version: Cog Spur VM 5.0 (release) from Feb 3 2017 (downloaded from files.pharo.org) This error results in Athens (and Roassal) not working, although Pharo itself seems fine. Reopening the image has no effect, and the only resolution is to do a system reboot. There is also crash.dmp from Feb 12 (possibly the day it started) containing ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Sun Feb 12 23:10:24 2017 Exception code: C0000005 Exception addr: 0040BDD0 Access violation (write access) at 00AFF43C EAX:FFFFFFFF EBX:74329850 ECX:549D7EBE EDX:00AFF43C ESI:74315F70 EDI:00489DB9 EBP:0887FF94 ESP:0887FF54 EIP:0040BDD0 EFL:00010206 FP Control: 0000027F FP Status: 00000000 FP Tag: 0000FFFF Crashed in some other thread ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Makes me wonder whether the SurfacePlugin.dll didn't somehow get corrupted... but then again there's no modification date change on the dll file, nor would it explain why rebooting fixes it. Thanks, Peter

Any plans for locale-specific printing and parsing of Date, Time, Number, etc.?
by Richard Sargent March 31, 2017

March 31, 2017

I think the title pretty well states it. I see nothing in the Pharo 5.0 download that allows locale-specific printing. Is there a well-defined API available? Is it on the road map for a future Pharo version? (If so, for any specific version?) Thanks! -- View this message in context: http://forum.world.st/Any-plans-for-locale-specific-printing-and-parsing-of… Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Google Summer of Code - New Trait Implementation
by tesonep＠gmail.com March 31, 2017

March 31, 2017

Hello, I am planning in working in a new Traits implementation, the idea is to have an implementation that can work as a loadable module. So you can use it or not as another library. Also the idea is improve the support of all the tools by improving the polymorphism between traits and classes. Clean up a little the API and add support to have stateful traits. I would like to know if you have any suggestion or have a problem that I could try to solve. I have been talking with some people in the community to get ideas, but always having more opinions is better. Thanks in advance. Pablo -- Pablo Tesone. tesonep(a)gmail.com

Path>>/ and ..
by Alistair Grant March 30, 2017

March 30, 2017

Hi All, The current implementation of Path>>/, while functional, seems to me to create poorly formed paths, e.g.: ('/a/b/c/d' asFileReference / '../e') path ==> "Path / 'a' / 'b' / 'c' / 'd' / '../e'" As can be seen above, the last segment is '../e'. I would expect the result to be: "Path / 'a' / 'b' / 'c' / 'e'" Is there a reason for the current behaviour? If not, are people open to modifying Path>>/ to produce the suggested result above (in Pharo 7)? The method below produces the modified result above and doesn't change the result of running all automated tests. If this is going to be added to Pharo 7 I'll create an additional automated test to check that it is working properly. Cheers, Alistair 'From Pharo6.0 of 13 May 2016 [Latest update: #60451] on 29 March 2017 at 9:40:41.681228 am'! !Path methodsFor: 'navigating' stamp: 'AlistairGrant 3/29/2017 09:39'! / aString | path | aString isEmptyOrNil ifTrue: [ Error signal: 'Path element cannot be empty or nil']. ^self resolve: (Path from: aString) ! !
