[Pharo-project] Fwd: [squeak-dev] Re: FFI and FreeTypePlus problem?
================================================================ Hi there, I'm using Installer to make a custom 3dot10 7159. The first things I do in the script is to load from universe FreeTypePlus (wich brings FFI). Then I've load LPF. If I do that it never ends due to Squeak not being able of resolving a name. NetNameResolver addressForName: 'installer.pbwiki.com/f/LPF.st' Before loading the FreeTypePlus, evaluating the previous sentence has an instant response of the address. But if I do load the FreeTypePlus package it never ends. Maybe an FFI issue? I'm in Win32 using SqueakFFIPrims.dll from 8/30/2007 Squeak.exe from 6/5/2007 any clue? thanks Sebastian Sastre PD: here is the beginning of the script: Utilities informUser: 'Upgrading universe packages' during: [ UUniverse systemUniverse updatePackagesViaWWW ]. (UUniverse systemUniverse newestPackageNamed: 'FreeType Plus') ifNotNilDo: [ :package| |inst| inst := UGlobalInstaller universe: UUniverse systemUniverse. inst planToInstallPackage: package. inst doInstall ]. (HTTPSocket httpGet: 'installer.pbwiki.com/f/LPF.st') readStream fileIn. ================================================================ I already created a bug report for this, Andreas may be able to tell you more: http://bugs.squeak.org/view.php?id=6980 As a workaround you can can use FFI-Kernel-ar6.mcz instead of FFI-Kernel-ar-8.mcz.

Yeah, I had forgotten about the problem. The issue comes from a call to Smalltalk>>recreateSpecialObjectsArray (which is required for the FFI to work correctly) and which accidentally nukes the external semaphore table. The fix is simple: Replace the following line in SystemDictionary>>recreateSpecialObjectsArray
newArray at: 39 put: Array new.
by "Preserve external semaphores when recreating splObjs" newArray at: 39 put: (self specialObjectsArray at: 39).
Also, saving and restarting the image after loading the FFI is good temporary workaround for this problem.
Cheers, - Andreas

I think it is this bug... http://bugs.squeak.org/view.php?id=6980 I have been following the conversations re: FT2Plugin etc. , but haven't had time to comment.
