[Pharo-project] Halo lost in linux and others quirks

by jdinunci＠uc.edu.ve

Hello, I'm new to smalltalk, I've been trying squeak for some time, and recently I discovered pharo, so I downloaded the files and started to play with it. The problems: *) Halos behave inconsistently: I can only activate halos in the world menus. If I middle-click in the workspace, the preference browser or any other window, they don't appear. *) Preference Browser -> Keyboard: If I deactivate duplicateAllControlAndAltKeys and duplicateControlAndAltKeys, no matter the state of swapControlAltKeys, actions like copy are always invoked by the alt key. *) If I use the window menu -> window color and *drag* the pointer over the palette, the system slows down and the mouse is captured by the palette for several seconds (the more time you drag, the more time you need to regain control). Where I'm tenting: @ work: Intel Core2 Duo, 2GB RAM, Ubuntu 9.10 64 bits @ home: Intel, 512MB RAM, Ubuntu 9.10 32 bits What I'm testing: set #1: pharo-vm-0.15.1b-linux, pharo0.1-10373web09.07.2.zip set #2: pharo-vm-0.15.1b-linux, pharo0.1-10379dev09.07.3.zip set #3: exupery 0.15-linux, pharo0.1-10373web09.07.2.zip set #4: exupery 0.15-linux, pharo0.1-10379dev09.07.3.zip all sets with SqueakV39-sources.zip In all sets, both machines, the problems were the same. I've been playing with squeak 3.9 installed from the official ubuntu repository in both machines and it runs fine. I tried using that interpreter with the pharo images and it couldn't read the images due to version mismatch (6502 vs. 6504). I' tried to compile the last squeak but I didn't had all dependencies at hand, and it was too late. Thanks -- Ing. JosÃ© Dinuncio Unidad de Redes TelemÃ¡ticas Universidad de Carabobo

Re: [Pharo-project] Show stopper network bug on Windows

by Schwab,Wilhelm K

Sig, Respectfully, I do not agree that the current situation is elegant. There are other ways to cope with a disabled plugin (see #useOldNetwork), and littering code with #initializeNetwork is error prone and wasteful in its own way, no matter how lean the method might be. This looks to me like an anachronism. There was no better mechanism, so a workaround had to suffice. Now with weak collections and events, it should be possible to do better. If those things do not work well, then they need to be challenged and fixed as appropriate. The lack of fully qualified names could easily be a windows stupidity. My Dolphin code for lookups has long been a little complicated: look up this, clear that, do it again, and it always seemed that I was fighting lack of imagination from the general direction of Redmond WA - who would have thought that possible? :) My favorite was win2k from (IIRC) pre-sp3: the only machine one could not find by name was the local host!

Â Also, on Windows, I am not getting the fully qualified name, which is another problem.

" NetNameResolver initializeNetwork ---------- another way could be just add the #startUp method and initialize network there. But i think that current solution is more elegant, because if your image never using the network, it will never initialize the plugin and in this way, preserve some resources. And , of course , there could be the cases, where VMs built without network support, or running with disabled networking security setting (for sandboxing). In these cases this primitive (as well as rest of socket prims) will fail. As for retreiving a fully qualified name - can't give you answer right now.
