.. towncrier release notes start

4.1.1 (2026-10-11)

  • Bound the shared-lock contention test by worker progress so slow CI machines can finish the workload. :pr:819
  • Avoid the macOS /dev/fd lookup implicated in a kernel panic by opening SQLite through a validated hard link. The database directory must be writable and support hard links; alias creation failure raises OSError. :pr:820
  • Ignore non-ASCII PID or start-time fields and out-of-range PIDs in ReadWriteLock hard-link directory names so forged owners cannot abort acquisition. :pr:821
  • Use Python 3.15 for development and automation. :pr:816

4.1.0 (2026-10-09)

  • Import :data:~filelock.OwnerMode, :data:~filelock.CompromiseReason and :data:~filelock.has_fcntl from filelock. :pr:790
  • :class:~filelock.AcquireReturnProxy is generic in the lock type, so with lock.acquire() as held: types held as the lock's own class. :pr:803
  • A :class:~filelock.Timeout from a soft lock names a holder on another host or in another PID namespace, which no contender ever reclaims. :pr:815
  • :attr:~filelock.SoftFileLock.is_lock_held_by_us and :attr:~filelock.MarkerSoftFileLock.is_lock_held_by_us return False for a marker an earlier process with the same PID left behind. :pr:774
  • :class:~filelock.SoftFileLock removes its marker when writing it fails and closing the descriptor fails too, so the lock path no longer stays blocked. :pr:775
  • :meth:~filelock.BaseFileLock.acquire and :meth:~filelock.BaseAsyncFileLock.acquire no longer wait past timeout when poll_interval is longer than the time left. :pr:777
  • :class:~filelock.SoftReadWriteLock ignores a generation-log entry whose name is not 20 ASCII digits, which used to stop its heartbeat thread or delete real generations. :pr:778
  • :class:~filelock.ReadWriteLock, :class:~filelock.SoftReadWriteLock and their async wrappers treat a :data:math.inf timeout like -1 and raise :class:ValueError for a blocking nan one. :pr:779
  • :class:~filelock.ReadWriteLock and :class:~filelock.SoftReadWriteLock accept a timeout above :data:threading.TIMEOUT_MAX instead of raising :class:OverflowError. :pr:780
  • :meth:~filelock.BaseFileLock.acquire raises :class:ValueError for a blocking nan timeout or a poll_interval above :data:threading.TIMEOUT_MAX, and treats a :data:math.inf timeout like -1. :pr:781
  • :class:~filelock.SoftFileLock and :class:~filelock.MarkerSoftFileLock treat a marker cut before its final newline as malformed, so a crash-truncated record self-heals and a read mid-write no longer breaks a live lock. :pr:782
  • :class:~filelock.UnixFileLock no longer deletes another process's live marker when it falls back to a soft lock on ENOSYS, and on macOS a lock path ending in a separator raises :class:FileNotFoundError instead of retrying. :pr:785
  • :class:~filelock.SoftFileLock and :class:~filelock.SoftFileLease put back a live successor's marker that a racing stale break moved aside, so a third contender no longer acquires beside the successor. :pr:786
  • :class:~filelock.StrictSoftFileLock removes every claim a failed acquire published, counts an EEXIST link that

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
