[Pharo-project] Memory problems on Windows
by Jimmie Houchin Sept. 4, 2010

Sept. 4, 2010

Hello, I am developing an application which processes and generates a large amount of data. In a recent attempt I encountered an Space is Low error. This is occurring in a Pharo 1.1 image using the latest Pharo and Cog VMs. I am opening the vm with the -memory: 1000 parameter. The below code I have applied the from the Squeak list from the 100 Million Objects thread. But the problem occurs at about 500mb of ram on a computer with 3 (or 6) gb of ram, with only 65% of physical ram in use. The os is Vista. Any help in using more memory, as much as necessary for the app, would be greatly appreciated. initializeMemorySettings "Initialize the memory and GC settings to be more in line with QF requirements" "The following settings affect the rate incremental GCs and tenuring" "Limit incremental GC activity to run every 40k allocations" SmalltalkImage current vmParameterAt: 5 put: 40000. "allocations between GCs (default: 4000)" "Limit tenuring threshold to only tenure w/ > 10k survivors" SmalltalkImage current vmParameterAt: 6 put: 10000. "tenuring threshold (default: 2000)" "These settings affect overall memory usage" "Only give memory back to the OS when we have more than 16MB free" SmalltalkImage current vmParameterAt: 24 put: 16*1024*1024. "default 8MB" "Try to keep 8MB headroom at all times" SmalltalkImage current vmParameterAt: 25 put: 8*1024*1024. "default 4MB" "These settings describe what to do when we're close to running out of free space" "Tell the VM that we'd rather grow than spinning in tight GC loops" SmalltalkImage current gcBiasToGrow: true. "default: false" "Tell the VM to do a fullGC for good measure if the above growth exceeded 16MB" SmalltalkImage current gcBiasToGrowLimit: 16*1024*1024. "default: 0" Thanks, Jimmie Houchin

[Pharo-project] Loop while debugging #expectedFailures
by Mariano Martinez Peck Sept. 4, 2010

Sept. 4, 2010

Hi. There is a loop when trying to debug #expectedFailures. To reproduce, just put a "self halt" at the beggining of a #expectedFailures method and then run of the tests of that class. The problem is that when you put the self halt, in an #expectedFailures, it brings a debugger, of course. But the debuggers needs to send the printOn to all the stuff in the context. TestResult implements printOn: in this way: printOn: aStream aStream nextPutAll: self runCount printString; nextPutAll: ' run, '; nextPutAll: self expectedPassCount printString; nextPutAll: ' passes, '; nextPutAll: self expectedDefectCount printString; nextPutAll:' expected failures, '; nextPutAll: self unexpectedFailureCount printString; nextPutAll: ' failures, '; nextPutAll: self unexpectedErrorCount printString; nextPutAll:' errors, '; nextPutAll: self unexpectedPassCount printString; nextPutAll:' unexpected passes'. which...as you can see sends the message #expectedPassCount which at the ends...sends #expectedFailure.....sooo....loop :) I am still thinking which could be the better solution. I will try to come up with it later. Cheers Mariano

I yearn for package comments, especially when hunting for a starting point in a new package. What say you? Sean p.s. For reference, I started a Squeak issue with links to previous discussions here - http://bugs.squeak.org/view.php?id=7558. -- View this message in context: http://forum.world.st/Package-comments-tp2525056p2525056.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

Stef, Does that mean that 1.1 will be patched accordingly? I have been thinking of building a new 1.1 image but can safely postpone that until this is ready if that is the intent.

[Pharo-project] TestSprinter
by Benjamin Van Ryseghem Sept. 3, 2010

Sept. 3, 2010

Hello everybody I'm now working on a new Test Runner tool and I wonder which behaviours do you want me to implement. For now, I want the Test Sprinter to be able to : - search through packages and classes thanks to search fields. - browse the hierarchy from packages to test methods (with icons). - create groups of tests easily re-runnable. If you have any ideas, I'm waiting for them ;) Thank you Ben
