This is spoiling the efficiency of git for merging... I think that the answer is yes though, because not every one is using git (think Eliot's branch). Esteban is not publishing the MC packages back on SmalltalkHub for nothing. Those MC package would not be usable if they loosed their history, and I'm not sure that we are ready to loose that... Yet, resolving the (real code) merge conflicts in an external tool does not feel so cool to me, I'd like to specify git mergetool --pharo ;) Another way would be to not attempt a merge at all via git, it would be simpler to just pick the mc package somewhere, but I don't like it, we're loosing git traceability (and those nice github networks). Otherwise, if development was exclusively git driven, then we would be more comfortable with git tools. But still, we have the image which is a working copy, and not necessarily in sync with gitfiletree, so we have a more complex process than file based environments anyway : one more indirection. image <-> files <-> staged files <-> repo There is still one super-cool feature where git shines that we can use: jumping from one branch to another (modulo the image sync with files), the most usefull one IMO when we are mixing external platform files and Smalltalk code that require some sync.

Hi Nicolas, from what you describe (double merge: one in git, one in MC), I wonder if my decision to maintain compatibility between gitfiletree and FileTree by writing the metadata (version / methodProperties) in gitfiletree is a good thing?

The last few days I migrated most projects of our projects from pharo2.0 to pharo3.0. And on the same time the images moved from an ubuntu 12.04. system to a ubuntu 14.04 system. Looking at the top command it appears the images/vms need noticable less CPU or better the tools report less. The monitored overall CPU usage also is much lesser than before. >>> >>> This is not proved by any measurement.

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
