[Pharo-project] PipeableOSProcess #close
by Schwab,Wilhelm K Nov. 27, 2010

Nov. 27, 2010

Dave, FWIW, I also ran into this one: http://article.gmane.org/gmane.comp.lang.smalltalk.squeak.general/121000/ma… Is there a time when a user/programmer would want to send #close rather than #closePipes? Perhaps #close could become #basicClose with #close then being changed to send #closePipes. #closePipes seems like something that might be private; it's (almost) obvious now, but it looks like a recurring trap for casual users. It appears that I had been having intermittent problems with this for a while. Yesterday, I ran a big batch that would not go to completion, and I noted that after the first error, pretty much every file operation failed. The latter lead me to strongly suspect cleanup of the pipes, and the above was then easy to find. The batch runs nicely now. Bill

Comment #1 on issue 3238 by stephane.ducasse: Use Class instead of TextDiffBuilder in changelist http://code.google.com/p/pharo/issues/detail?id=3238 Note that apparently in squeak they changed to go from word to characters and now they are back to word for diffing.

[Pharo-project] Weird problem...having several "implementors" for the same method and class
by Mariano Martinez Peck Nov. 27, 2010

Nov. 27, 2010

Sorry, I know the subject of the mail is confusing, I am confused myself. Ok, I am doing hacky stuff and playing with CompiledMethod proxies, but I have a problem searching for implementors. So, I have for example CompiledMethodProxy >> mareaUninstall. But when I search for implementors of "mareaUninstall" in the popup of implementors it shows FOUR times, "CompiledMethodProxy >> mareaUninstall"... why ??? it should appear only once.. I attach an screenshot. Does anyone know what can be happening? thanks in advance, Mariano
