I may have missed some cases, but to me the cases when checkout may try to overwrite an ignored file are essentially: * Someone "git add"ed a file meant to be ignored by mistake (e.g. "git add -f *.o"). * A file that was meant to be kept private (e.g. config.mak.dev) ends up being tracked. This may happen when we find a way to make per-developer settings the same for everyone. I both cases I'd want at least to be notified that something is going on, and in the second I'd probably want to keep my local file around. > If we feel thrashable is stretching it too far (which I don't think it > is), we could add a "core.ignore_files_are_trashable" setting that > brings back the old semantics, for those who have a strong feeling about it. May I remind an idea I sugested in an old thread: add an intermediate level where ignored files to be overwritten are renamed (eg. foo -> foo~ like Emacs' backup files): https://public-inbox.org/git/vpqd3t9656k.fsf@xxxxxxxxxxxxxx/ One advantage of the "rename" behavior is that it's safer that the current, but still not very disturbing for people who like the current behavior. This makes it a good candidate for a default behavior. This could come in complement with this thread's "precious" concept: * If you know what you're doing and know that such or such file is precious, mark it as such and Git will never overwrite it. * If you don't know about precious files, just keep the default setting and the worse that can happen is to get your file overwritten with a bakup of the old version kept around. This would probably play better with a notion of "precious" files than with a notion of "trashable" files. -- Matthieu Moy https://matthieu-moy.fr/
