✨ Restrict running sessions to one concurrent one#258
Open
Conversation
Restrict running sessions to one concurrent one. Uses the `XDG_RUNTIME_DIR` to hold an exclusive runtime lock. The lock is automatically cleaned up upon exit. An earlier implementation used the `fs4` crate, but now this functionality is in the `stdlib` since `rustc --version`: `1.89.0`. Closes: #179 Supercedes: #182

Alternatively we could also add a drop `impl`, and call `eguis` native exit handling.

Restrict running sessions to one concurrent one. Uses the `XDG_RUNTIME_DIR` to hold an exclusive runtime lock. As opposed to #258, we don't block starting a new session on the lock, but clean up the old session and start a new session. The end result is similar: There will only be one `centerpiece` session open at the same time. Alternatives: - Use #258 for the other behavior - Link directly to the C functions for kill, but we depend on `libc` transitively anyway already - shell out to the `kill` command, this would mean we depend on the external `kill` command for this functionality
