Thanks a lot for your answer. That's really good arguments that i was waiting for and that i have not get until now. My comprehension now : - it's not easy to maintain several versions of a binary file in parallel. So basically, it's not recommanded to have complex workflow for binary files. In case the project has a low number of binary files, it can be handle by simple communication, In case the project has a lot of binary files, a simple workflow with a centralized workflow is recommanded - git doesn't hate locks, it's just that it's not the layer to implement it because git is workflow independant. Locks depend on a centralized server which is directly linked to the workflow. I'm not trying to implement a such workflow. I'm just curious, reading a lot of things about git, and trying to understand what is sometimes called a limitation of git. A simple line in the documentation to say that locking should be handled in the upper layer (and it's done for example in gitolite) because it's dependant of the workflow could help some people looking about that point. Thanks a lot for git. 2013/9/17 Fredrik Gustafsson <iveqy@xxxxxxxxx>: > On Tue, Sep 17, 2013 at 09:45:26PM +0200, Nicolas Adenis-Lamarre wrote: >> Ooops.
