   Certain operations on Python's built-in types are atomic and are therefore thread-safe guaranteed by the GIL, such operations include push, pop, and extend on lists and dictionaries. A script is written to check whether these operations are still thread-safe without the GIL.

   2 days ago · Starting with the 3.13 release, CPython has experimental support for a build of Python called free threading where the global interpreter lock (GIL) is disabled. Free-threaded execution allows for full utilization of the available processing power by running threads in parallel on available CPU cores.

   Nov 5, 2024 · Free-threading is an experimental feature in Python 3.13 that allows CPython to run without the Global Interpreter Lock (GIL). The GIL is a mutex preventing multiple threads from executing Python bytecode simultaneously. This design choice has simplified CPython's memory management and made the C API easier to work with.

   How to build Python 313 without free threading & JIT support?

   • So, you’re going to build the vanilla flavor of Python 3.13 without free threading or JIT support. Ensure that your current working directory is where you compiled Python 3.13 before, and remove any generated build files with make clean. Then, configure the build without the experimental features and compile Python again.

   Does Python 313 support JIT?

   • That’s where Python 3.13 comes in. When you build Python 3.13 with the experimental JIT support, you’ll enable a lower-level execution layer called the Tier 2 interpreter, which breaks down Python bytecode into even more granular instructions.

   How to enable free threading & JIT compiler in Python?

   • Navigate into the parent folder containing the Python source code, which you extracted from the downloaded archive in the previous step: Make sure to adjust the path as necessary if you opted for a more recent Python 3.13 release. Now, you can run the configure script with custom build flags to enable free threading and the JIT compiler:

   Does Python 313 support free threading?

   • In contrast, most I/O-bound tasks handled by web servers will benefit little from free threading in Python 3.13 because they don’t inherently depend on the CPU. You’ll run multiple instances of the same task simultaneously and observe how Python copes with each additional thread of execution.
