The kind of stuff I would have love to see people experimenting with Squeak. We failed to be sexy on the UI level.

Ah, well I can also help eliot on this, sometimes he gets too busy... plus I want to ensure the objective-c binding happens.

[Pharo-project] networking problem (repost)
by Michael Roberts March 11, 2010

March 11, 2010

i'm not sure this email came through whilst the list was down sunday/monday so i am reposting by request. i will add some further content at the end ===================================================== I have dug around the network problem (OS X) in Pharo 1.0. I am convinced #useOldNetwork = true does not work. Looking through old core images, it never worked; at least with my current OS and VM choice. i have been using Magma as a test case. Indeed it is broken on 10508 rc2, however if I set NetNameResolver classPool at: #UseOldNetwork put: false and hack #initializeNetwork to make the reference false as well (since it can change its value once set)... I can run the first 10mins of the Magma test suite which is heavy on network use. I only can't complete the magma test case due to unrelated issues. I've asked Chris to see if these changes work for him. i propose in Pharo Core 1.0 -set UseOldNetwork := false, and change all references that try and set it to true -now we are only using the new network infrastructure, -gather fresh test cases from the community where networking fails and fix them with a final push. -do not try and fix the UseOldNetwork := true branches If we can not get this approach above to work then as a fallback I propose to remove all the new network code and revert it all back to the point where it was simpler where socket addresses were just byte arrays...We then spend more time in 1.1 trying to get it to work properly. Does anyone care at this point how the infrastructure looks in 1.0? The fact that our rc2 network layer is totally bust is enough to do something drastic to finish the cycle. I propose in Pharo 1.1 -strip out all useOldNetwork = true branches. it does not work, and it is a mess to have these two branches side by side, especially when the value of useOldNetwork can change on its own (this happened a number of times to me) I guess due to all the attempts to check and initialize the network. somewhere it flips. obviously we need some focus on testing a final set of changes, but please consider the direction I outline. thanks, Mike ==================================================== I spent some time after writing this above looking at the magma test case more deeply and chatting to Chris offline. After fixing a quoting issue with magma image launching i managed to get the magma test suite to run for about 30 mins (until it stopped...). So in principle the networking does work... Then to my astonishment i could not get it to run again at all for another few hours, i got no where... it was like it was a dream. I suspect the problem is the exact network interfaces that the server and client try to connect/bind to. In the old ipv4 world it was fairly simple. i suspect in the ipv6 world, different parts of magma are binding to different interfaces and i find it impenetrable to work out which. i have lots of interfaces on my machine (wifi, ethernet, parallels virtual, etc) and when you do NetNameResolver localHostAddress (or whatever the message is) you get back only the first one. I think this could be the cause of issues. Adrian mentions to me John thought they came back randomly. So now my conclusion is firmly we have to take a step back and simplify. for pharo 1.0 unless we have someone with a lot of time i do not feel we can untangle the resolver and socket code. We should revert it back to the original #[192 168 0 10] style code when it used to be simple. This assumes the primitives still support this. Then what I would like to see in Pharo 1.1 or 1.2, is that we separate out classes for ip4 and ip6 support, and make them work cleanly and transparently together. Just because we have ip6 support i don't want to be forced to use it. we should have a clearer interface to enumerate all the network interfaces on the machine, and we should really document this heavily. I think the new help system would be great for this. I started to have to write my own scripts just to document the change in API across images. these can go straight into a help system... cheers, Mike

[Pharo-project] LAST CHANCE Foreing Function Interface GSOC [WAS] Re: [smalltalk-research] Re: [Esug-list] Google Summer Of Code 2010 news!!!
by Mariano Martinez Peck March 11, 2010

March 11, 2010

Tomorrow morning we will be submitting...so, for this project, we only have this proposal: Work on a cross-dialect foreign function call interface and implement it in at least two dialects. Candidates include Alien and GNU Smalltalk's CObject (using existing implementation has the advantage of having to implement in only _one_ other dialect!). Bonus points for implementing a C parser that would be able to construct bindings. GNU Smalltalk already contains a C preprocessor implementation. There is some support for parsing C headers in the Newspeak system. Aliens have been ported to Strongtalk as well as Squeak. The mentor will be John McIntosh and Gilad Brancha co-mentor. Can this proposal be more complete and have similar structure to the rest ? If true, send me the proposal.

[Pharo-project] VM crash on Windows
by Schwab,Wilhelm K March 11, 2010

March 11, 2010

Hello all, I am having a sudden problem with Pharo crashing on Windows - it's quitting on handling Seaside requests, and I'm getting **no** information. The VM pops up the output console, writes a lot of (probably useful) information to it, and then promptly exits. Is there any way to get it to log the output? So far, the things I have found online say that it will write a dump when it crashes, but it's not doing it. Bill

[Pharo-project] For those who use Nabble ....
by Geert Claes March 11, 2010

March 11, 2010

I managed (with some assistance from Nabble support) to group several Smalltalk mailing lists on Nabble under the common category "Smalltalk" (http://n4.nabble.com/Smalltalk-f1294792.html) To get them all to appear together the Pharo forums had to move Pharo to the a common n4 server or something, so the links to the Pharo-Smalltalk and Pharo-Smalltalk-Users forums need to be updated on the Pharo website (although the old links will still work for some time) to: Pharo-Smalltalk: http://n4.nabble.com/Pharo-Smalltalk-f1294837.html Pharo-Smalltalk-Users: http://n4.nabble.com/Pharo-Smalltalk-Users-f1310670.html -- View this message in context: http://n4.nabble.com/For-those-who-use-Nabble-tp1310998p1310998.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

Can we apply the script in issue 1850 to 1.0 and 1.1 to add the repo with metacello configs as one of the standard repos.
