Re: [Pharo-dev] Tell me about your workflow

by GOUBIER Thierry

Yes! Ok, you're probably reaching over 60% of the time spent writing to disk. I'll try to think over the problem and see if I can come up with something simple and efficient... either within the current filetree format, or with another (future) format. At the moment, this would mean that, as a rule of thumb, splitting a large package over a few sub-packages could be a good idea once we reach about 200 ~ 300 classes in a package.

If to write less I have to compute a lot, do file reads and compares, md5 hashes, a diff... I'll probably replace a lot of writes by a lot of CPU time in Pharo and maybe be slower overall (not to mention more error prone). Would you be ready to run some profiling code on your set ? I can make a simple test case. I also wonder if writing less could make the git commit faster, in which case it could be valuable. sure, send me the instructions Also, if you want to try gitfiletree and your repository, what you can try is just browse your repository and browse versions of your packages (browse, not load: a browse will load your package code components but not compile the code). ok, how should I install it?

Git is slow: on Roassal, Waiting for the git commit : 67% Writing the package to disk : 20% (writing the version file: 0.4%) -> No real cost associated with the metadata -> git is a lot more than I expected. When I remove git (i.e. pure filetree) Making a snapshot of Roassal: 28.9% basic Store version : 67% writeBasicDefinitions : 30% (of which half of it is reordering some stuff, not writing) writeMethodHolderDefinitions: 27,8% Of which writing to disk effectively is 19.7% Conclusion: gitfiletree will look slow because git is slow on such large commits :( And I don't see much gains to be made on the writing (i.e. a format change won't help much), but a lot to loose (code complexity, bugs).

It is good doing experiments with new or better developer tools. But some parts just looking as "quickly hacked into it", just to make it running. And there are bugs. Nautilus could need some refactoring/code cleanup. In my point of view, in a clean and stable pharo release, all smalltalks tools (browser debugger inspectro ...) should show you "look, thats the way of doing it in smalltalk /pharo". I would really like to more emphasis on "clean and stable". nicolai
