Summary by CodeRabbit

  • New Features

    • Added functions to get and set the interpreter's thread switch interval via the system module.
  • Bug Fixes

    • Updated tests so that checks for thread switch interval settings are now treated as normal tests, not expected failures.
    • Removed expected failure markers from several threading and functools tests, improving test reliability and coverage.

Walkthrough

The changes introduce support for Python's thread switch interval configuration by adding getswitchinterval and setswitchinterval functions to the sys module, backed by a new switch_interval field in the VM state. Corresponding tests are updated to treat related cases as normal tests, removing expected failure decorators.

Changes

File(s) Change Summary
Lib/test/test_sys.py, Lib/test/test_syslog.py, Lib/test/test_functools.py, Lib/test/test_threading.py Removed @unittest.expectedFailure decorators from tests related to switch interval and threading.
vm/src/stdlib/sys.rs Added getswitchinterval and setswitchinterval functions to expose thread switch interval control.
vm/src/vm/mod.rs Added switch_interval field to PyGlobalState and initialized it in VirtualMachine::new.

Poem

A switch interval, set with care,
Now Python threads can fairly share.
The sys module gains new might,
To get and set intervals just right.
Tests now run without dismay—
Hooray for progress, hip-hip-hooray!
