Marker formats here hold the field to printable non-space ASCII, while ``socket.gethostname()`` reports whatever the kernel stores: a space, a newline that forges an extra marker line, or a byte no codec encodes, which Python hands back as a surrogate. A holder that publishes one raw writes a marker it cannot read back, and loses the lock to the first peer that ages it out as malformed. ``?`` is illegal in a hostname, so escaping it along with every out-of-grammar byte as ``?`` leaves a real name untouched and still keeps two hosts apart, which :func:`owner_is_stale` relies on to refuse to probe a foreign PID. An over-long name ends in a digest of the part cut to fit the limit. A bare cut gives every name that shares the kept prefix one identity, and :func:`owner_is_stale` would then probe a local PID for another host's holder. c3RK|]"}|tvrt|nd|dV#dS)r 02xN)r chr).0bytes R/home/spazio/kingdom_calls/venv/lib/python3.11/site-packages/filelock/_identity.py zhost_name..!sS 000D n$nnnzutf-8surrogateescapeN-r ) joinsocket gethostnameencodelenr rhashlibsha256 hexdigest)namekeeps r host_namer)s 77&((//9JKK  D 4yy###"77!;uu+jjtDEE{/A/A/C/C D D N N P PQgRgQg hjj ;3rpidinthostname start_token int | Noneboolc|tkrdSt|sdS|dSt|}|duo||kS)a Whether the recorded owner is provably gone, so reclaiming its marker cannot detach a live holder. Fail closed: return ``True`` only when this process can prove the exact recorded owner is dead. A marker from another host cannot be probed; a live PID whose start token still matches, or whose token cannot be read, is the holder or is indistinguishable from it; a live PID whose start token differs is a recycled PID, so the process that wrote the marker is gone. PostgreSQL, Qt ``QLockFile`` and Mercurial all break a stale lock only on proof of death and treat an unreadable or foreign owner as still holding.
