[Pharo-project] Socket timeout terminates COG VM
by John Toohey Oct. 11, 2011

Oct. 11, 2011

Hi, I've had a problem since 1.0 with socket timeouts throwing exceptions and invoking the debugger in my headless images. I don't know why a socket timeout is considered exceptional, but I've gotten used to using VNC to log into the server and close the debuger windows. However, I've moved to COG and the latest one-click images, and now the error terminates the VM. My app is a standard Seaside server, using the streaming connector for Comet support. I've attached the PharoDebug.log. It would be appreciated if anyone could help me with this problem, as I'm at a loss where to even begin. Using Pharo1.3 #13298 on Lucid32 (Ubuntu) -- ~JT

[Pharo-project] Migrating Complex in a separate package
by Nicolas Cellier Oct. 11, 2011

Oct. 11, 2011

Hi, Facts: - Complex is present in Squeak trunk image but not used in Kernel - Complex is absent from Pharo image. This breaks portability of some packages. I suggest putting Complex in its own package in squeaksource. This can work for Pharo alone. I also suggest to optionally remove Squeak.Complex from trunk. There are then other choices: - the name of the package : can be Complex or Math-Complex (I already put a few Math-* in squeak source...) - the name of the class can be Complex or ComplexNumber Specifically I don't like isComplex, many objects could respond true because complicated; isComplexNumber is much more explicit. We could also think of having complex expressions in a symbolic algebra, and isComplexNumber would be true only for a literal value.. What I could eventually do is publish an old Complex in package Complex for backard compatibility and an updated ComplexNumber in a Math-Complex package... How many of you use Complex ? What do you think of these proposals ? Nicolas

[Pharo-project] Remove/deprecate String adaptation?
by Henrik Sperre Johansen Oct. 10, 2011

Oct. 10, 2011

Could we please remove, or at least deprecate the String>> #adaptTo*: andSend: protocol? Made me question my sanity a bit when I forgot some parenthesis, and 0.1 + 0.2 storeString didn't raise any errors, nor returned the string like I'd intended it to... Cheers, Henry
