While I agree both "git config"'s external interface and internal implementation are not suited for bulk update, I have a suspicion that the config mechanism is not the right place to store this information in the first place. The config is a per-Git-repository state that is not versioned, which means it is applicable regardless of individual commits or trees (also it means it is designed not to be shared across repositories). But "You may see a file here that otherwise should not be there only to mark that there should be an empty directory" is an attribute to a particular tree, isn't it? If you have a branch that git-svn adds a placeholder file (hence you want to annotate that tree with "This directory is there only to hold the placeholder file") and you want to perform a merge on the Git side of that branch with another Git branch that does have real contents in that directory, you would want the result to say "This directory no longer is just for a placeholder", but you cannot say that globally by updating the config file, as the config mechanism is also applied to the original branch that came from git-svn, in which the directory in question is still only to hold the placeholder file. A Subversion-only history does not have a reason to have .gitignore file tracked in it; wouldn't a cleaner implementation to consider a directory that has .gitignore and nothing else marked with "added placeholder", without (ab)using the config mechanism? If you are worried about a corner case where the Subversion side adds the file, even though it is not used there, probably you can add a single comment line "# added by git-svn only to keep the directory" and consider a directory that has nothing but .gitignore that consists of only that exact comment line an "added placeholder" directory to work it around. Either approach would tie the information to the tree state, which sounds like a much more correct approach to the "keep empty directory" problem to me. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
