To put it in another way: what would happen if trees were removed from git's repository completely? Instead we would just stipulate that git should only track files, not trees, and that it would remove an outside directory when removing the last file from the repository that can't be accomodated without such a directory. Now the effect would be that git would become quite inefficient. But it would not change its behavior in any other way. Because it knows _zilch_ about directories. It knows about the hierarchy of the _contents_, but the directories, the physical entities in the work tree? It deduces a convenient point of time to try deleting them (when a tree collapses), and it deduces that they are there as long as it is tracking their content, but no information about a _directory_ other than its _contents_ ever enter the repository or index. About its _existence_, git only keeps circumstantial evidence. -- David Kastrup, Kriemhildstr. 15, 44793 Bochum - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
