[Pharo-project] Alien & Squeak FFI issues on Snow Leopard.
by John M McIntosh Sept. 30, 2009

Sept. 30, 2009

Someone finally managed to fire up a Sophie app http://www.opensophie.org/ on Snow Leopard and immediately found an issue that also affects Squeak users who do fascinating things with FFI The innocent FFI call was apifstat: afileNo statBuffer: buffer <cdecl: long 'fstat' (long MacStat* ) module: 'libc.dylib'> ^self externalCallFailed Now it seems BEFORE Snow Leopard *somehow* the Squeak external primitive call api which is part of the VM to assist in loading plugins or finding function entry points in executable binaries or libraries would return the entry point for fstat by *somehow* finding libc.dylib which is via /usr/lib/libc.dylib -> libSystem.dylib -> libSystem.B.dylib Interestingly this is found implicitly since the mac carbon vm lookup logic never looks in /usr/lib/ Now in Snow Leopard it seems they do less implicit searching, perhaps a security concern? Then it fails. In the past the Unix VM would search a hundred(sic) more places, but I understand less today, but it might still work? Maybe /usr/lib is in the hit list? This issue also applies to Alien because it calls back to the VM for it to find the module and function entry point. Since I have received a request to ensure that doing an explicit full path should be allowed in the squeak carbon macintosh vm. Then a change would be: apifstat: afileNo statBuffer: buffer <cdecl: long 'fstat' (long MacStat* ) module: '/usr/lib/libc.dylib'> ^self externalCallFailed I'll look at doing this shortly. However the workaround is to go to Sophie.app/Contents/Resources and do a ln -s /usr/lib/libc.dylib libc.dylib to create a symbolic link in the Resources directory for libc.dylib since we do explicitly look for libc.dylib in the Resources directory. Obviously if you have a FFI call like above where you are calling a system library Oracle? for example. You might find it no longer works with Snow Leopard on the Macintosh, so you should check. -- = = = ======================================================================== John M.

Re: [Pharo-project] [squeak-dev] Mac carbon VM goes to 4.2.2Beta1U
by John M McIntosh Sept. 29, 2009

Sept. 29, 2009

Ok, I've altered the master Squeak 4.2.2beta1U.app.zip and added the signature file. Also I've attached it. People who have made copies (like for the pharo site) might want to re- download it to ensure you've the correct zip file. found via http://smalltalkconsulting.com/squeak.html On 2009-09-29, at 9:12 AM, Bert Freudenberg wrote: > > On 27.09.2009, at 23:49, John M McIntosh wrote: >> >> I've also uploaded the new VM as Squeak 4.2.2beta1U.app.zip >> found via >> http://smalltalkconsulting.com/squeak.html > > Is it intentional there is no "Squeak VM Opt.sig" anymore? > > - Bert - > > -- = = = ======================================================================== John M.

[Pharo-project] Update 10458 fails with MNU
by Martin McClure Sept. 29, 2009

Sept. 29, 2009

Downloaded 09.09.3, install fresh, launch, System->update. Runs for a while, then fails while loading 10458. Failure is MNU. In [] in ScriptLoader>>loadTogether:merge: the code [:fn | loader addVersion: (self loadVersionFromFileNamed: fn)] Is failing, #loadVersionFromFileNamed: is answering nil when fn is 'Gofer-lr.48.mcz'. And, indeed my package-cache does not contain 'Gofer-lr.48.mcz', but it does have Gofer-lr.51.mcz. Regards, -Martin

[Pharo-project] Morph extension
by Gary Chambers Sept. 29, 2009

Sept. 29, 2009

After some experimenting I can get over 10% perfromance improvement with window operations when fillStyle; borderStyle; hResizing; vResizing are made as instance variables of Morph, rather than going through extension. I thought Marcus has mentioned this some time ago, but no progress? There is obviously an issue with name collision/shadowing but not many methods in core need changing to accomodate. Whilst on the subject I am wondering on everyone's opinion on merging the behaviour of color/borderColor/borderWidth with that of fillStyle... sure to be some gains there! Regards, Gary
