[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.

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]

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.

Hi all, does anybody knows if the Pharo Launcher is working in Windows? I tried on different Windows 7 machines, but it would work nor give any error message at all. (Note: Pharo3 windows distribution did work). Thanks, Thierry

[DEV] Systemd socket activation patch for the VM
by Max Leske Nov. 14, 2014

Nov. 14, 2014

Hi folks As promised a long time ago my colleague Nik Lutz has finalized the patch for the VM that enables socket activation with Systemd. I will quickly go over what the patch is supposed to achieve, how we plan to use socket activation and what (minimal) changes are necessary. Systemd Socket Activation: Systemd opens a (network-) socket and waits for connections. When the first client connects the assotiated service (VM) is started. Systemd indicates via environment variable (LISTEN_FDS) that it opened a network socket. Detailed documentation on socket activation with Systemd can be found here: http://0pointer.de/blog/projects/socket-activation.html Our scenario for socket activation: At Cmsbox we have hundereds of images running on a server, all of which listen on a dedicated network port for incoming connections. The server is powerful enough to run all these processes concurrently, especially since not every image receives requests all the time. With socket activation we could further lower the server load and free up resources for images with a high request rate. Images that donât receive any requests for a specified amount of time can be suspended automatically and reactivated when a request comes in. The VM Patch: The attached patch tries hard to be minimal. It defines a new socket type (ProvidedTCPSocketType) which you will also find in the image (Socket>>newSystemd). ProvidedTCPSocketType is special in that it can refer to an existing TCPSocket and does not necessarily entail the creation of a new socket. The changes in the image: - Socket>>newSystemd tries to open a new Systemd socket. - TCPListener>>haveSystemdAssignedPort tests if the LISTEN_FDS environment variable has been set by Systemd for the current process. - TCPListener>>primEnvironmentAtSymbol is a utility method that we need to check for the environment variable (IMPORTANT: copied from OSProcess; uses the OSProcess plugin) - TCPListener>>pvtNewListener: has been modified to include the check for the Systemd port. If the socket has been assigned by Systemd, use a Systemd socket, a TCP socket otherwise Quick Howto: - Adapt path to vm and image in pharo@.service - Take a Seaside image and FileIn systemd.cs (tested with http://seaside.st/distributions/Seaside-2.8.4.zip) - Save as 9999.image - Copy pharo@.service and pharo@.socket to /etc/systemd/system - As root run: systemctl daemon-reload systemctl start pharo(a)9999.socket - Open http://localhost:9999/seaside/config [- systemctl stop pharo(a)9999.socket] -> Upon connection pharo(a)9999.socket starts: pharo(a)9999.service (which would start .../9999.image) You can see this in action in the following screencast: http://youtu.be/MVPLZNKg5j8 We hope that this patch (or some version of it) will find its way into the VM. If you have any questions please feel free to ask. Cheers, Max (on behalf of Nik and the rest of Netstyle.ch)
