chore: bump invoke 2.2.0 -> 2.2.1 for Python 3.14 compatibility#992
Conversation
invoke 2.2.0 raises SystemError on Python 3.14: 3.14 tightened fcntl buffer-overflow detection, and invoke's termios.TIOCGWINSZ probe was reading too few fields of a 4-field winsize struct. Any uv run invoke <task> aborts before the task body when stdout is a TTY. invoke 2.2.1 (2025-10-10) unpacks all four fields and discards the unused two -- pure compat fix, no behavior change. See opsmill/infrahub#9128 for the equivalent bump on opsmill/infrahub. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Whensys.stdoutis a TTY, anyuv run invoke <task>(or--list/--help) aborts before the task body.invoke 2.2.1 (2025-10-10) unpacks all four fields and discards the unused two — pure compat fix, no behavior change. Upstream fix: pyinvoke/invoke#1040. Equivalent bump on the main repo: opsmill/infrahub#9128.
