Hi Andreas,

I was about to write to you because I suspected of the semaphores. Thanks for the workarround I'll try it as soon as I can. A curios fact is it wont happen in an ubuntu (32bits).

thanks again I will provide feedback of my win32 experience,

cheers

Sebastian Sastre

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

As a workaround you can can use FFI-Kernel-ar6.mcz instead of FFI-Kernel-ar-8.mcz.

Hi Andreas, I was able to finally make my 3dot10 nicely with the patch,

thanks,

Sebastian

wont happen in an ubuntu (32bits).

There are many variations in which the problem will not show (for example, when it comes from the cache instead from the net, or if code is invoked in the middle which resets the network, or if the previous lookup went to the same host, or if there is DNS failure in the middle etc). The way to make it happen reliably is like this:

NetNameResolver addressForName: 'www.squeak.org'. Smalltalk recreateSpecialObjectsArray. NetNameResolver addressForName: 'ftp.squeak.org'.

Without the fix to recreateSpecialObjectsArray, this should fail, no matter where.

Hi sam

can you tell us more (some of us like me will not attend OOPSLA). From which VM did you started?

Declaring Tuesday Night as Squeak BOF time is fine with me. Anyone for whom that is a problem should speak up sooner than later.

By the way I can more or less claim to be a local for this event (I live about an hour away) so if anyone needs some sort of assistance (I don't have a van but can manage a certain amount of airport/taxi duty perhaps) let me know.

Wow, that is great to know!

I was discussing this with Göran. Traditionally the date gets decided on only in the week before the event, but I am trying to include a detour to Nashville in a trip I will be taking and would really need to know this now.

Fortunately there is another tradition that in the end almost always the date that gets picked is Tuesday night, so for now I am supposing that this will be the case for this year as well. Wednesday and Thursday include official events at night and so aren't a good option. Monday includes two interesting events all day (the Lisp 50th anniversary celebration and the "Smalltalk Superpowers" workshop, unfortunately they are simultaneous) but all official activities end at 5pm.

So then it is DECIDED. :) I will bring my video recorder as usual and later serve up the talks as torrents. Mmmm, aha, here is already a swiki page for OOPSLA 2008, let people sign up who wants to present something:

http://wiki.squeak.org/squeak/6080

Ken, do you have a projector you could bring? Just in case, see the wiki page for info on how it went last year. :)

Unfortunately I don't; I don't do presentations. I could look into the possiblity of renting own locally.

Remember the user/pass is "squeak/viewpoints".

and the squeak.org site seems down

can anyone confirm this?

Affirmative.

And, for you information, list.squeakfoundation.org/squeakfoundation.org had no DNS as well as squeak-dev/sqeuak-beginners were out of order from at least October 17th to October 21th.
