Hello, In other programming languages (this is specific to Linux/Unix systems), in the past to ensure security in the even of a program crash, we would do something like:
1. Create a temporary file and squirrel away the file handle 2. Unlink the temporary file by name 3. Various functions would write stuff to the file 4. If the programs completes to some successful state, create a hardlink to the file handle with the final filename I'm finding this very difficult to do in Go, as there does not seem to be a way to do #4. And this is a very important consideration for this piece of the system. For example, os.Rename takes filenames as the old/new filename. I figured looking in that code might reveal something lower level that could be used, which lead me to syscal_linuxl.Rename() That lead me to syscall_linux.RenameAt() Which led me to zsyscall_linux_amd64.go. .. at this point I got pretty lost on how to do any of this. _AT_FDCWD and fishing around in what appears to be some pretty low-level internals of Go... Is there some way to achieve this or a way that can ensure these files are always removed if the program is kill -9'd, terminates from a panic, etc. Thanks!
