Re: [Pharo-project] Fwd: MouseOverHandler

by Adrian Lienhard

Hi Hernan, The reason this was not integrated is that nobody marked it as 'fixed' nor tagged it as 1.0. Is this critical for 1.0? Cheers, Adrian BTW, if anybody sees changes/fixes not being integrated please ask on the mailing list.

Re: [Pharo-project] Author = TestRunner

by Adrian Lienhard

If I understand you correctly, the author is permanently set to 'TestRunner' after running tests? Do you know which tests cause the problem? Reverting to the original author is done in an ensure block, so I don't see how that can go wrong right now.

Re: [Pharo-project] vm on ubuntu

Agreed that naming it Pharo would be better, but the name is of less interest to me than the vm sources. If there are Pharo-specific changes, I do not see them anywere??

[Pharo-project] call for helping me sorting out what to integrate :)

by StÃ©phane Ducasse

Hi guys It would help me to know the pending bugs that you fixed and that we should integrate. Of course everything should be on the bugtracker but I would like to know for example when there is a consensus for the hash implementation when it is ready to go in 1.1. In the meantime I will go over the bugtracker and pick up what is available (ie tagged 1.1 and fixed). It is important that we tag systematically the issues that will be integrated in 1.1 as 1.1 so that after we can follow. Some of the old entries integrated in 1.0 are not tagged 1.0 and may be we should script the bugtracker. Stef
