xlocal
execution locals: killing global state (including thread locals)
Decision gist · record as of 2026-08-14
No. The package is abandoned (last release 2012-11-16, no maintenance since), has unclear licensing, high install friction (zip-only distribution), and unspecified Python version support. Modern alternatives provide similar functionality with active maintenance. Use only if maintaining legacy code already depending on it.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Python version support is unspecified; package was last released in 2012 and may not work on modern Python versions.
- High install friction: distributed as a zip file rather than a wheel or sdist.
- Package is abandoned—last release was 2012-11-16 with no commits or maintenance activity since.

What it is and what it does
xlocal implements execution-local storage—a restricted variant of thread-local storage where attribute bindings are scoped to a context-managed code block and all functions it calls, rather than persisting globally or thread-wide. Attributes set via a with-statement are visible to all code invoked within that block, including nested function calls, but are automatically cleaned up when the block exits and do not leak to other threads or greenlets.
The package is designed for frameworks and libraries that invoke handler or plugin code and want to pass execution-specific state without using globals or thread locals. It prevents called code from rebinding state of its caller and ensures clean lifecycle management. However, the package has been abandoned since 2012-11-16 and is not actively maintained.
Use it for
- Pass request-specific context to handler functions spawned in threads or greenlets without using globals.
- Implement per-execution state in web frameworks or plugin systems where multiple concurrent executions need isolated bindings.
- Prevent state leakage when invoking user code that should not modify the caller's execution context.
- Manage thread-local or greenlet-local state with explicit lifecycle control via context managers.
