gevent v20.9.0 Release Notes

Release Date: 2020-09-22 // over 3 years ago

  • 🔋 Features

    • The embedded libev is now asked to detect the availability of clock_gettime and use the realtime and/or monotonic clocks, if they are available.

    On Linux, this can reduce the number of system calls libev makes. Originally provided by Josh Snyder. See :issue:issue1648.

    🛠 Bugfixes

    • On CPython, depend on greenlet >= 0.4.17. This version is binary incompatible with earlier releases on CPython 3.7 and later.

    On Python 3.7 and above, the module gevent.contextvars is no longer monkey-patched into the standard library. contextvars are now both greenlet and asyncio task local. See :issue:1656. See :issue:issue1674.

    • The DummyThread objects created automatically by certain operations when the standard library threading module is monkey-patched now match the naming convention the standard library uses ("Dummy-12345"). Previously (since gevent 1.2a2) they used "DummyThread-12345". See :issue:1659.
    • 🛠 Fix compatibility with dnspython 2.

    .. caution:: This currently means that it can be imported. But it cannot yet be used. gevent has a pinned dependency on dnspython < 2 for now. See :issue:1661.
