Your asking the question over (and over... and over...) doesn't make it an FAQ. :-) Aside from your asking over and over, it hasn't come up that often, actually. The right answer has been known for decades, and it's is very simple; write a temp file, copy over the xattr's and ACL's if you care (in many cases, such as an application's private state files, it won't care, so it can skip this step --- it's only the more generic file editors that would need to worry about such things --- but when's the last time anyone has really worried about xattr's on a .c file?), fsync(), and rename(). This is *not* hard. People who get it wrong are just being lazy. In the special case of dpkg, where they are writing a moderate number of large files, and they care about syncing the files without causing journal commits, the use of sync_file_range() on the files followed by a series of fdatasync() calls has solved their issues as far as I know. - Ted -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of "unsubscribe".
