Thanks Camillo Bruni. http://code.google.com/p/pharo/issues/detail?id=4607 - Issue 4606: Fix drawing shadow of morphs. Thanks Igor Stasenko. http://code.google.com/p/pharo/issues/detail?id=4606 and I could not type enter on workspace I could everywhere else.

[Pharo-project] Strange bug in text selection
by Igor Stasenko Aug. 10, 2011

Aug. 10, 2011

which leads to #basicNew: primitive fail, because it passing a negative number (no surprise, it fails). According to stack trace, a Text>> copyFrom:to: is called with arguments: start = 100 stop = 44 (instead of having start = 44 , stop = 100) it is called from MultiNewParagraph>>buildSelectionBlocksFrom:to: method. I don't know whether we should fix this method, or maybe it is better to fix #copyFrom:to: to accept inverted ranges (a simple check if stop < start then swap the end points) yet it hard to reproduce, it works ok most of the times :( To reproduce the bug, try to do following: - open a new workspace window, type an arbitrary text there - then drag a window to the bottom of desktop, so only title bar of workspace remain visible - release drag - click on the title bar and start dragging it back to make text visible -- Best regards, Igor Stasenko AKA sig.

[Pharo-project] We need to condense changes in 1.4

I think it is time to condense changes, because file is grown too large (28Mb) -- Best regards, Igor Stasenko AKA sig.

[Pharo-project] News about NativeBoost
by Igor Stasenko Aug. 10, 2011

Aug. 10, 2011

Hello, Major news: NativeBoost now working on Macs! The main problem with Mac OS platform was that it requires a stack alignment discipline, while other platforms don't. So, i had to extend the assembler to make sure that all external calls will be made with properly aligned stack. Also, i spent time to improve error handling. Since in Cog/Stack VMs we having nice primitive error code, now it can report what caused a failure in more detail, than just failing a primitive and leaving a language side to guess what gone wrong. There's a lot of other small changes, like new tests, more examples etc.. But i don't want to describe them all (and frankly i don't remember all of them ;) Things not yet working: The callbacks to language side is not functional (i have to revise this code to synchronize it with callback machinery in Cog VMs). The callbacks to native code working well (of course, because it don't needs to deal with VM-specific stuff ;) The prebuilt VMs, which contain a NativeBoost plugin are now on Jenkins server. These VMs will be built automatically each time there is code update for Cog VMs (in same way as all continuous integration jobs). The only difference between original Cog VMs and Cog+NativeBoost VMs is that they contain NativeBoost plugin. So, you can use these VMs instead of Cog VMs if you like. You can download VMs from here: https://ci.lille.inria.fr/pharo/view/NativeBoost/ To install NativeBoost into your image follow instructions on: http://code.google.com/p/nativeboost/wiki/Installation -- Best regards, Igor Stasenko AKA sig.

[Pharo-project] About configurationOfPharoRB
by StÃ©phane Ducasse Aug. 9, 2011

Aug. 9, 2011

Hi there is stable: spec <symbolicVersion: #stable> spec for: #'pharo1.0.x' version: '1.2.1'. spec for: #'pharo1.1.x' version: '1.5'. spec for: #'pharo1.2.x' version: '1.7'. spec for: #'pharo1.3.x' version: '1.7'. spec for: #'squeak4.x' version: '1.6'. Now I'm confused because there is only a version 1.0 in this configuration. Did I miss something obvious or this is just deadcode? Stef

Hi I would like that we do an analysis of what should stay in implementors Here are the menus in 1.2 and 1.4 Please comment so that we can add what is really used. As a general comment I would avoid to do everything with a single tool. Stef

[Pharo-project] Web app security
by laurent laffont Aug. 9, 2011

Aug. 9, 2011

Hi, with a public SmallHarbour (public fork of SeasideHosting - smallharbour.org) people can upload images that do bad things: change filesystem, run commands, .... Actually, what are the ways of securing a server so people can't do bad things ? I'm thinking of: - run the vm/image within a low right unix account - remove dangerous plugins (OSProcess, ?) Can we easily chroot ? what are known solutions ? Laurent.

[Pharo-project] Polymorph improvements
by Gary Chambers Aug. 9, 2011

Aug. 9, 2011

Hi all. I've added an issue with some tweaks/improvements to a few Polymorph classes. http://code.google.com/p/pharo/issues/detail?id=4590 Groupboxes can now have dynamic content (model/getContentSelector based). Abaility to create icon lists via builder/TEasilyThemed. Expander labels now LabelMorphs rather than TextMorphs (can therefore appear as disabled) IncrementalSliderMorphs now honour minWidth/minHeight in layouts Panel morphs allow event based mouse over handling (call to super was missing). Label groups allow for nil labels (equates to empty string) Regards, Gary
