To some degree that revalidates my interpretation of Andreas' statements. If I understand it correctly eacht time a shell command is executed, which requires tree interaction, the corresponding tree is read from filesystem to memory completely before anything is done? So if I git-add a file, the whole index is read first, then the memory object is changed and then the resulting change is written to disk bottom-up from the point of view of the tree? -- 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
