Overview ¶
Package atomicfile writes a file a watcher reads: whole or not at all, and not at all when it already holds what would be written. Traefik reloads on every write to the directory it watches and reads a half-written file the moment it appears, so both the Traefik routing adapter and the Docker runtime's edge certificates (R-417) write that way. A leaf package, as internal/registrylimit is, so adapters may import it.

Functions ¶
func WriteIfChanged ¶
WriteIfChanged writes body to path through a temporary file renamed into place, unless path already holds body. The directory is created if missing.
The temporary file's name is its own (CreateTemp), as keyfile.place's is: route sync, the reconciler and a deploy may write one route at once (R-417), and with one fixed name a writer renamed another's half-written file into place. It is hidden and has no .yml or .toml extension, so a watcher does not load it.
