[Pharo-project] PharoCore 1.3: Transcript Ctrl+S broken

by Lukas Renggli

Another problem I just noticed right now is that pressing Ctrl+S in the Transcript opens a debugger: SubscriptOutOfBounds: 0 Ctrl+S used to clear the transcript, what I found quite useful in the past. Again, I am reporting this here to not forget, because the bug tracker is currently in read-only mode. Lukas -- Lukas Renggli www.lukas-renggli.ch

[Pharo-project] PharoCore 1.3: Implementors browser broken

by Lukas Renggli

I just noticed that the implementors browser in Pharo Core 1.3 does not show any kind of warning if a variable is not declared. Also parse errors result in the fatal SyntaxError window. I thought I report it here before I forget it again, because the bug tracker is in read-only mode right now. Lukas -- Lukas Renggli www.lukas-renggli.ch

[Pharo-project] Recursive calls hang image

by Sean P. DeNigris

My image hung after executing: categoryName := $- asParser negate plus flatten, ($- asParser, #any asParser star flatten) optional star. categoryName parse: 'SuperMe'. On the Moose list [1], Lukas pointed out the bug in my code which led to direct recursion, and that hanging under this circumstance was a bug in Pharo. Is this a known bug, or shall I file an issue?

I'm confused. Is there a bug in pharo, or janko loaded a strange package?

According to its use (see senders to #mouseOverHandler) it actually handling more than just mouse over events. I would say it should be named MouseEventHander :) But still , its hard to say, why it is so complex.. and what its purpose. -- Best regards, Igor Stasenko AKA sig.

Re: [Pharo-project] FSGit for new Filesystem implementation

Thanks max. Stef > Hello everyone. > > I'm happy to announce that Camillo (with a little help from me) has adapted FSGit to run with the new Filesystem implementation (version 2.0.1).

Re: [Pharo-project] [Vm-dev] Re: Troubles with #flushCache and #run:with:in:

by Jorge Ressia

Hi Eliot, I am experiencing the same problem as Lukas. I was having random DNU on replaced methods. I fixed the problem by flushing the cache on the compiled methods only, before I was flushing on the selector and on the class. It is not yet clear to me what is the right way of flushing the cache. Any explanation on that? I think that this goes along with http://code.google.com/p/pharo/issues/detail?id=2255 http://forum.world.st/flushCache-with-MethoWrappers-in-CogVM-td3381310.html Eliot, if you need help debugging or testing a potential solution let me know, I have a bunch of test working on top of this.
