Add builtin "git rm" command This changes semantics very subtly, because it adds a new atomicity guarantee. In particular, if you "git rm" several files, it will now do all or nothing. The old shell-script really looped over the removed files one by one, and would basically randomly fail in the middle if "-f" was used and one of the files didn't exist in the working directory. This C builtin one will not re-write the index after each remove, but instead remove all files at once. However, that means that if "-f" is used (to also force removal of the file from the working directory), and some files have already been removed from the workspace, it won't stop in the middle in some half-way state like the old one did. So what happens is that if the _first_ file fails to be removed with "-f", we abort the whole "git rm". But once we've started removing, we don't leave anything half done. If some of the other files don't exist, we'll just ignore errors of removal from the working tree. This is only an issue with "-f", of course. I think the new behaviour is strictly an improvement, but perhaps more importantly, it is _different_. As a special case, the semantics are identical for the single-file case (which is the only one our test-suite seems to test). The other question is what to do with leading directories. The old "git rm" script didn't do anything, which is somewhat inconsistent. This one will actually clean up directories that have become empty as a result of removing the last file, but maybe we want to have a flag to decide the behaviour?

git-rm: update to saner semantics This updates the "git rm" command with saner semantics suggested on the list earlier with: Message-ID: <Pine.LNX.4.64.0612020919400.3476@woody.osdl.org> Message-ID: <Pine.LNX.4.64.0612040737120.3476@woody.osdl.org> The command still validates that the given paths all talk about sensible paths to avoid mistakes (e.g. "git rm fiel" when file "fiel" does not exist would error out -- user meant to remove "file"), and it has further safety checks described next. The biggest difference is that the paths are removed from both index and from the working tree (if you have an exotic need to remove paths only from the index, you can use the --cached option). The command refuses to remove if the copy on the working tree does not match the index, or if the index and the HEAD does not match. You can defeat this check with -f option. This safety check has two exceptions: if the working tree file does not exist to begin with, that technically does not match the index but it is allowed. This is to allow this CVS style command sequence: rm <path> && git rm <path> Also if the index is unmerged at the <path>, you can use "git rm <path>" to declare that the result of the merge loses that path, and the above safety check does not trigger; requiring the file to match the index in this case forces the user to do "git update-index file && git rm file", which is just crazy. To recursively remove all contents from a directory, you need to pass -r option, not just the directory name as the <path>. Signed-off-by: Junio C Hamano <junkio@cox.net>

Add builtin "git rm" command This changes semantics very subtly, because it adds a new atomicity guarantee. In particular, if you "git rm" several files, it will now do all or nothing. The old shell-script really looped over the removed files one by one, and would basically randomly fail in the middle if "-f" was used and one of the files didn't exist in the working directory. This C builtin one will not re-write the index after each remove, but instead remove all files at once. However, that means that if "-f" is used (to also force removal of the file from the working directory), and some files have already been removed from the workspace, it won't stop in the middle in some half-way state like the old one did. So what happens is that if the _first_ file fails to be removed with "-f", we abort the whole "git rm". But once we've started removing, we don't leave anything half done. If some of the other files don't exist, we'll just ignore errors of removal from the working tree. This is only an issue with "-f", of course. I think the new behaviour is strictly an improvement, but perhaps more importantly, it is _different_. As a special case, the semantics are identical for the single-file case (which is the only one our test-suite seems to test). The other question is what to do with leading directories. The old "git rm" script didn't do anything, which is somewhat inconsistent. This one will actually clean up directories that have become empty as a result of removing the last file, but maybe we want to have a flag to decide the behaviour?

git-rm: update to saner semantics This updates the "git rm" command with saner semantics suggested on the list earlier with: Message-ID: <Pine.LNX.4.64.0612020919400.3476@woody.osdl.org> Message-ID: <Pine.LNX.4.64.0612040737120.3476@woody.osdl.org> The command still validates that the given paths all talk about sensible paths to avoid mistakes (e.g. "git rm fiel" when file "fiel" does not exist would error out -- user meant to remove "file"), and it has further safety checks described next. The biggest difference is that the paths are removed from both index and from the working tree (if you have an exotic need to remove paths only from the index, you can use the --cached option). The command refuses to remove if the copy on the working tree does not match the index, or if the index and the HEAD does not match. You can defeat this check with -f option. This safety check has two exceptions: if the working tree file does not exist to begin with, that technically does not match the index but it is allowed. This is to allow this CVS style command sequence: rm <path> && git rm <path> Also if the index is unmerged at the <path>, you can use "git rm <path>" to declare that the result of the merge loses that path, and the above safety check does not trigger; requiring the file to match the index in this case forces the user to do "git update-index file && git rm file", which is just crazy. To recursively remove all contents from a directory, you need to pass -r option, not just the directory name as the <path>. Signed-off-by: Junio C Hamano <junkio@cox.net>
