[Pharo-project] curl / http request
by Camillo Bruni April 24, 2011

April 24, 2011

I am too dumb and there is too little documentation which is hard to find :). So can anyone tell me how I do the following bash thingy in pharo? curl $URL --data-binary $SOME_FILE -H 'Content-type:application/json' I don't manage to get this working properly. I guess HTTPSocket is the class to use... thanks a lot camillo

[Pharo-project] Fwd: [Vm-dev] Re: out of memory - cog on windows
by Mariano Martinez Peck April 24, 2011

---------- Forwarded message ---------- From: Andreas Raab <andreas.raab(a)gmx.de> Date: Fri, Apr 22, 2011 at 3:01 PM Subject: Re: [Vm-dev] Re: [Pharo-project] out of memory - cog on windows To: vm-dev(a)lists.squeakfoundation.org FWIW, the reason for the 512MB limit has to do with Windows memory layout. When you're running applications that load dynamic libraries (directly or indirectly such as when using ODBC which loads further DLLs) Windows needs (sometimes a lot of) address space to map these DLLs in order to load them[*]. When the VM starts it grabs MAX_VIRTUAL_MEMORY from the OS which will consequently not be available to map DLLs into. We have found that depending on the libraries in use and depending on the overall system utilization, loading DLLs would fail seemingly "at random" which, after further investigation, we were able to track to reserving too much address space upfront. We were able to show experimentally, that changing the limit from 1GB to 512MB would on some machines make all the difference. [*] This is true in particular for libraries that create more threads as the default Windows policy is to create threads with the stack size of the application executable. Thus a 1MB default stack in the application will by default create all further threads to be allocated with a 1MB stack size. Of course all of this is subject to various other conditions. In the end we concluded that 512MB is a reasonable size for most apps and with 512MB we've never seen these random failures. You can increase the limit by recompiling the VM, but if you ship your app in diverse environments you should be aware of the potential issues.

I can compile the VM for you with this change in 5 minutes. But I am not sure that such simple code would make it work. I think such limit is there because of something.

[Pharo-project] About (nil@nil)
by StÃ©phane Ducasse April 23, 2011

April 23, 2011

with manuel oriol we started to play with the idea of a randomTester in Pharo. It poses a lot of questions. Now doing the first experiments, I found an instance of point (nil@nil) (besides reciprocal broken on Point (0@0) and (Point allInstances select: [:each | each x isNil]) first pointersTo points me to recreateSpecialObjectsArray I looked into the literals and others and I could not find. Each time I execute Smalltalk recreateSpecialObjectsArray I get a new nil@nil objects.... but forcing a GC garbage them. But I still have this nil@nil object around. Does anybody have an idea from where nil@nil could come from? Stef

[Pharo-project] A ready only transcript does not fly
by StÃ©phane Ducasse April 23, 2011

April 23, 2011

Fernando I think that we should rollback the transcript. because this is really annoying that we cannot use the transcript: copy and paste execute an expression there. May be this is better to improve the ThreadSafeTranscript. The new one looks like a regression and I'm quite sure people will not like it. So this was a good try but we should recognise when stuff do not work as good as we wanted. Stef
