Re: [Pharo-project] Call for your input on questions you ask yourselves during merge

by Max Leske

Here's one (a bit off limits maybe): will my merge (or the commit) be readable by all of my images? Background: Monticello packages with traits are stored slightly different in current Pharo versions than in Squeak. This means that I cannot load such a package version that has been saved with Pharo into Squeak (actually, I can. But it's all a bit of a mess). The consequence is that I have to save changes to such a package from a Squeak image and then load them in Pharo even though the actual development would have happened in Pharo.

[Pharo-project] VM freezes sending #basicNew to Stream subclass

by Larry White

Hi, Throwing this out there because it may be a bug. I'm running the Seaside one-click install on OS X Lion. Pharo1.3 Latest update: #13302 I can reliably cause my VM to freeze up and need to Force-Quit it from the OS. I'm implementing (copying) the probability logic from the blue book. When I tried to create an instance of the Binomial class, the system hung. I can replicate the problem by sending the message #basicNew to ProbabilityDistribution. ProbabilityDistribution is a direct subclass of Stream and I haven't overridden or modified #basicNew. What's happening is that it fails in the BlockClosure [anObject doit], but only when I instantiate a member of this particular class hierarchy. In the probability classes, a #doIt in a Workspace hits the line "self suspend" in the #terminate method of Process and the VM hangs there. I believe they had ProbabilityDistribution subclass from Stream because sampling from a distribution is like reading from a Stream, but I don't think any there's any actual shared code, so I switched the superclass of ProbabilityDistribution to Object and the code works fine now. Thanks. Larry

Someone with knowledge of RunArray and RemoteString should check this. I removed code that referenced the removed classes, but don't understand RunArray and RemoteString well enough to be sure that I didn't mess anything up. All RunArray's tests still pass, but RemoteString didn't seem to have any. -- View this message in context: http://forum.world.st/COTDC-86-TextURL-tp4119838p4128775.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.
