But of course, there is allways 1 conflict : the MC meta information mc/VMMaker-oscog.package/monticello.meta/version Since the branch was not forked from latest master, every other feature branch will rot as soon as you integrate the first one. That's the major limitation of gitfiletree. The way I found to workaround this is to : git checkout master start an image in interactive mode, make sure to have current version from gitfiletree loaded git fetch someRepo someBranch git checkout someBranch >From the image, open git file tree and copy modifiedPackage in local MC package-cache git checkout master git merge someBranch git mergetool answer remote/local as you like for .meta/version and say [y] it's fixed (you'll overwrite it soon after) >From the image MC merge modifiedPackage copy from the package-cache Republish the merged package in gitfiletree git commit -a -m "Merge pull request #... (fix someBranch)" That's a bit heavier than a pure MC workflow, but it's bearable IMO... Tell me if this sounds clear enough. Another possibility is to do the exact mirror of this operation : merge master branch in each someBranch. But I don't think it's viable : 1) If I have 10 branches, and don't know in which order you want to integrate, then I'll have to do it 10+9+8+... times - that's 45 times this operation 2) If I know the order, I'll do that job in a single someBranch, it is exactly the mirror of above operation : merge master into someBranch rather than someBranch into master. But then it's both fragile (it can rot at any time if you decide to interleave another fix), and it is against the spirit of git : the feature branch should carry the minimum of changes IMO. The only advantage of this approach is to reduce the bottleneck effect by reducing the work performed by the integrator, especially if you are alone to cope with this burden... Unfortunately I'm out of time right now. I wanted to blog about it, but blogging is taking time... Hope my explanations help.

Units package access

by Diego Lont

Hi all, I think I have found a bug in Units and would like to correct it. I am using Units, and although it has some quirks (100 kg * (10 m / 1 t) should be 1 m and not 1000 kilogram metres per tonne), it is working well for me. But one point is a problem for me: the â=â is no longer symmetric. The following things should be unequal: 10 kg = 10 s 10 kg = 10 10 = 10 kg But the thing is, that 10 kg = 10 actually returns true. So if someone can give me access I will fix this bug (with a test case). Regards, Diego

Re: [Pharo-dev] Debugging in Production Servers

by askoh

Thanks for all the comments. Let me distilled what I have learned. Correct me if I am wrong. In Smalltalk: Production environment and development environment are very similar if not identical. Runtime and debug modes are identical. So, debugging is instantaneous available. Debugging occurs at the context of the exception itself - not in a handler or somewhere else. Debugger, nah, the whole environment allows doit's, code changes and resumes always. Reflection is constantly available for debugging and logging. Can we coin a term for these capabilities/properties? Can we define a standard to gauge programming environments?
