The problem with FFI (and Alien) is that by using FFI and thus having the FFI plugin installed you completely circumvent any security you gain from the sandbox. This is only really interesting for an environment like etoys where you allow arbitrary scripts to be loaded. Right now we are not supporting etoys, but the question is what, down the road, is going to happen. Another question is how more use of FFI opens us up to issues other languages have. So far Smalltalk wasn't hackable (on the server), with FFI generally available it could be? If people vote this a non-issue I'm fine with it, but I wanted at least to raise the issue at hand.

No discussion really, but I think this would be nice. I personally think that a good FFI is base fuctionality, e.g. it allows to move glue-code into the image that normally would be in primitives. Now Alien does only support intel... so it's not there yet, even though there has been lots of progress (very nice!). So one idea could be to have both for now... and replace the old as soon as Alien is ready. Marcus -- Marcus Denker -- denker(a)iam.unibe.ch http://www.iam.unibe.ch/~denker

Re: [Pharo-project] OB Button colors

by David RÃ¶thlisberger

> When loading polymorph with Watery2 theme and SuperOB using the > ScriptLoader the buttons in OB tend to become green again after some clicking ... hm, Polymorph doesn't seem to honor what you specify in #defaultBackgroundColor of a model object for SystemWindow. Instead it always uses this gray color, while OB is thinking that the default background color it specifies gets used. This is a problem of Polymorph I think, so I won't fix that in OB.

True, but I was thinking beyond just the font path. Getting the Temp folder path, would also be useful. A general purpose function could do it all. e.g. getOSPath: 'fonts' getOSPath: 'temp' I seem to recall that that this has been discussed in the past on the squeak-dev list. > > >>> > -- > Best regards,> Igor Stasenko AKA sig.> > _______________________________________________> Pharo-project mailing list> Pharo-project(a)lists.gforge.inria.fr> http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project _________________________________________________________________ See the most popular videos on the web http://clk.atdmt.com/GBL/go/115454061/direct/01/
