Thatâs understandable I am signalling those things because I think they confuse newcomers even more. I was just installing Pharo on a new machine and I know where I can find those things but newcomers donât.

They are loaded in the pharo-vm/ when you get the vm with the zeroconf scripts. ââââââââââââââââââââââââââââââââââââââââââââââââââââââââââââââââââââââââââââââââ [26/10/2013 09:00.06] ~/temp [User.Techlab] â curl http://get.pharo.org/vmLatest | bash % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 5309 100 5309 0 0 18578 0 --:--:-- --:--:-- --:--:-- 69855 Downloading the latest pharoVM: http://files.pharo.org/vm/pharo/win/latest.zip pharo-vm/Pharo.exe Downloading PharoV10.sources: http://files.pharo.org/sources//PharoV10.sources.zip Downloading PharoV20.sources: http://files.pharo.org/sources//PharoV20.sources.zip Creating starter scripts pharo and pharo-ui [26/10/2013 09:00.31] ~/temp [User.Techlab] â ls -l pharo-vm total 24102 -rwxr-xr-x 1 User UsersGrp 72074 Oct 26 09:00 FT2Plugin.dll -rwxr-xr-x 1 User UsersGrp 3063538 Oct 26 09:00 Pharo.exe -rw-r--r-- 1 User UsersGrp 16235372 Oct 26 09:00 PharoV10.sources -rw-r--r-- 1 User UsersGrp 22239552 Oct 26 09:00 PharoV20.sources -rwxr-xr-x 1 User UsersGrp 73160 Oct 26 09:00 SqueakFFIPrims.dll -rwxr-xr-x 1 User UsersGrp 63012 Oct 26 09:00 SqueakSSL.dll drwxrwxr-x 1 User UsersGrp 0 Oct 26 09:00 __MACOSX -rwxr-xr-x 1 User UsersGrp 1398589 Oct 26 09:00 libcairo-2.dll -rwxr-xr-x 1 User UsersGrp 1776128 Oct 26 09:00 libeay32.dll -rwxr-xr-x 1 User UsersGrp 845192 Oct 26 09:00 libfreetype-6.dll -rwxr-xr-x 1 User UsersGrp 2740390 Oct 26 09:00 libpixman-1-0.dll -rwxr-xr-x 1 User UsersGrp 322014 Oct 26 09:00 libpng-3.dll -rwxr-xr-x 1 User UsersGrp 393728 Oct 26 09:00 ssleay32.dll -rwxr-xr-x 1 User UsersGrp 112654 Oct 26 09:00 zlib1.dll Phil

Re: [Pharo-dev] Use #shouldnt:raise: only with specific errors, or evaluate the given expression directly

by phil＠highoctane.be

I am using Pharo business wise. And making money out of it. It is using Seaside 3 and a ton of packages. They all work fine. What's your point really? If you want to go Pharo, you go Pharo and you don't look back. Or you haven't made your mind. In which case the complaints are useless. Phil

Fwd: use of pointsTo: for includesSelector:

by Eliot Miranda

---------- Forwarded message ---------- From: Eliot Miranda <eliot.miranda(a)gmail.com> Date: Fri, Oct 25, 2013 at 2:18 PM Subject: use of pointsTo: for includesSelector: To: The general-purpose Squeak developers list < squeak-dev(a)lists.squeakfoundation.org>, Pharo Development < pharo-project(a)lists.gforge.inria.fr> Hi All, I just got a little burned. I was searching through an Array of symbols and integers (it is the PrimitiveTable from the VM), wanting to filter-out methods with a with a certain pragma. The code looks like: anArray doWithIndex: [:entry :index| (self whichClassIncludesSelector: entry) ifNotNil: [:c| | m | m := c >> entry. (m pragmaAt: #option:) ifNotNil: [:pragma| (initializationOptions at: (pragma arguments first) ifAbsent: [true]) ifFalse: [anArray at: index put: 0]]]] the error was a keyNotFound error for c >> entry. Turns out entry was the integer 306, a code for a quick primitive that returns some inst var. The question is why did (self whichClassIncludesSelector: entry) evaluate to other than nil given that 306 is /not/ a selector in any of the classes from self on up. Well, it's MethodDictionary's use of pointsTo: that is at fault: MethodDictionary>>includesKey: aSymbol "This override assumes that pointsTo is a fast primitive" aSymbol ifNil: [^ false]. ^ self pointsTo: aSymbol ProtoObject>>pointsTo: anObject "This method returns true if self contains a pointer to anObject, and returns false otherwise" <primitive: 132> 1 to: self class instSize do: [:i | (self instVarAt: i) == anObject ifTrue: [^ true]]. 1 to: self basicSize do: [:i | (self basicAt: i) == anObject ifTrue: [^ true]]. ^ false Turns out that 306 was the tally of one of the method dictionaries along self's superclass chain. This seems to be to be completely bogus. Do we really need crude performance hacks like this any more? -- best, Eliot -- best, Eliot
