New Cog VMs available
by Eliot Miranda Nov. 16, 2014

Nov. 16, 2014

... at http://www.mirandabanda.org/files/Cog/VM/VM.r3133/. CogVM binaries as per VMMaker.oscog-eem.934/r3133 These VMs should be functionally identical to the 3126 VMs; the core VM differs only in having been compiled from generated source that has been refactored to enable convenient 32-bit to 64-bit Spur image bootstrap. I'm building and releasing them mostly to test that refactoring. However, there is new DNS support on Windows and SSL support on Unix. See below. Simulator/Slang: Refactor to allow 32-bit and 64-bit Spur to coexist in the simulator, thereby allowing a 64-bit bootstrap. Replace direct use of BytesPerWord, ShiftForWord, BytesPerOop and BaseHeaderSize with sends of wordSize, shiftForWord, bytesPerOop & baseHeaderSize respectively. Make sure these are still output as the manifest constants in the generated C. Eliminate use of bytesPerSlot in favour of bytesPerOop. The use of sends is similar to those in trunk VMMaker, but I don't have time to merge. Sorry :-(. Work-around use of sends for bytesPerOop in e.g. generateToByDo:on:indent: and users of isConstantNode:valueInto:. Do a better job at inlining via inlineCodeOrNilForStatement:in:. Comment in isNode:substitutableFor:inMethod:in: explains. Eliminate generic VM_LABEL support, labelling only the bytecodes in interpret. Eliminate use of LargeContextSize in the stack and cog VMs. Alas haven't yet eliminated the frame offset constants such as FoxCallerSavedIP et al. We only need one of the two word sizes of interpreter to be executable in the bootstrap. And remember to generate the GdbARMPlugin Add accessorDepths for the exported browser plugin primitives for Spur. Merge Levente's recent changes to DNS lookup on Windows and SSL on Unix. See http://squeakvm.org/cgi-bin/viewvc.cgi/squeak?view=revision&revision=2249 http://bugs.squeak.org/view.php?id=7824 Have the Unix & Mac VMs print the process id and working directory when blocking on error or assert fail. Add scripts for the ARM VM archives. -- best, Eliot

Configurations and Github for a specialised configuration browswe
by kilon alios Nov. 15, 2014

Nov. 15, 2014

So I am so happy with how Pharo works with Github, that I decided to even port my configurations there and I also decided to create a small configuration browser which will subclass the existing configuration browser for installing tools for my project Ephestos so I dont have to pollute the existing configuration projects with all my sub-projects. In sort I want to host configurations to Github similarly to how MetaRepos are host in Smalltalkhub. I want the user to be able to install those configurations without a need to install git I asked this I think before and I was told how to, but it was part of another thread and it got lost inside my email abyss. So How I do that ?

[Bloc] Getting involved
by Santiago Bragagnolo Nov. 15, 2014

Nov. 15, 2014

Hi Guys, (Alan and Steph punctually) I want to comment I am getting involved with Bloc, since i need to draw several things and i need an Athens canvas. I am checking if it is the best tool for my needs. In any case I am doing some contributions that i would like to commit and to share. Actually i am working on draft a window, a tool bar, a button based on images and animations. Then, there is any mailing list for Bloc? How is the push-request cycle? Thanks :). Santiago.

How to refresh the pharo window manually
by kilon alios Nov. 15, 2014

Nov. 15, 2014

Hello guys I am making a theme manager and I have observed that when I choose a background color for pharo windows it does not update properly. How I can force the whole pharo window to update ? I have found DisplayScreen and WorldMorph but no idea how to use them.

cross platform issue with versionner in pharo 3.0 - want a slice?
by Paul DeBruicker Nov. 15, 2014

Nov. 15, 2014

Hey - I'm thinking about making a slice to that versionner doesn't use Symbols for class names when creating baselines. The problem is that on GemStone symbols and strings don't compare as equal, so looking up a class in a repo fails. Is that slice something that is generally interesting ? Is it already fixed in Pharo 4? Thanks Paul

Pharo on Online Labs ARM cloud server ?
by Sven Van Caekenberghe Nov. 14, 2014

Nov. 14, 2014

Hi, I just saw this: http://labs.online.net which offers real ARM cloud servers (15 minutes for free to try out) [they're French]. This is Ubuntu 14.10 on ARMv7. Naturally I wanted to try Pharo on such a machine. The base question is, where do I get the latest and best VM to try this ? Maybe a complete & easy to use source tree that can be compiled locally ? And would it make sense to add some ARM option to get.pharo.org ? Thx, Sven

Spur Identity Hash [was: The Trunk: System-cmm.689.mcz]

Maybe we should think about separating those objects' logical > "value" hash from their identityHash in trunk..? That could be useful > when we move to 64-bit someday.. > Remember that Spur has a common header format for both 32-bit and 64-bit versions, so in both there is a 22-bit identityHash and hence the identityHashes of all objects in a 64-bit Spur image bootstrapped from a 32-bit Spur image will be _unchanged_. Convenient. So no need to worry. And it should be the case that a freshly bootstrapped 64-bit Spur image does not need to be rehashed to function properly. But while we're on the subject, one thing we could do is arrange that Symbols have an identityHash based on their value. So when interning a string we'd compute its string hash and derive and assign the identityHash of the Symbol from the string hash. That would mean that when unpickling classes in e.g. Fuel we would not have to rehash method dictionaries, which would be very nice indeed.
