Re: [Pharo-dev] github-cache organisation

Ben, I think I've found the bug ... Metacello intends that the zip file be downloaded to /tmp, but the code as implemented 3 years ago for Pharo was not actually downloading the file to /tmp ... thanks for pointing this out, I've created a Metacello issue for this[1] ... I will probably fix this shortly, but I'm not sure when (or if) my fix will be integrated into the Pharo-5.0 release.

Hi, This flow is taken into account in the new iceberg... I cannot go into details because I'm still on holidays (and no internet) until Monday... And Nico is also taking some days. Anyway, yes...

It's not a yes, neither a no. - We have automatized the dependency analyses - We added Lint rules that ensure that no new dependencies are added to the kernel because of an integration - We will be adding soon enough more tools to automatically validate and ensure the health of the bootstrap, and to detect possible problems.
