Remove sys.getcheckinterval() and sys.setcheckinterval() functions.
They were deprecated since Python 3.2. Use sys.getswitchinterval()
and sys.setswitchinterval() instead.
Remove also check_interval field of the PyInterpreterState structure.
.. versionadded:: 3.7
-.. function:: getcheckinterval()
-
- Return the interpreter's "check interval"; see :func:`setcheckinterval`.
-
- .. deprecated:: 3.2
- Use :func:`getswitchinterval` instead.
-
-
.. function:: getdefaultencoding()
Return the name of the current default string encoding used by the Unicode
implement a dynamic prompt.
-.. function:: setcheckinterval(interval)
-
- Set the interpreter's "check interval". This integer value determines how often
- the interpreter checks for periodic things such as thread switches and signal
- handlers. The default is ``100``, meaning the check is performed every 100
- Python virtual instructions. Setting it to a larger value may increase
- performance for programs using threads. Setting it to a value ``<=`` 0 checks
- every virtual instruction, maximizing responsiveness as well as overhead.
-
- .. deprecated:: 3.2
- This function doesn't have an effect anymore, as the internal logic for
- thread switching and asynchronous tasks has been rewritten. Use
- :func:`setswitchinterval` instead.
-
-
.. function:: setdlopenflags(n)
Set the flags used by the interpreter for :c:func:`dlopen` calls, such as when
Removed
=======
+* The ``sys.getcheckinterval()`` and ``sys.setcheckinterval()`` functions have
+ been removed. They were deprecated since Python 3.2. Use
+ :func:`sys.getswitchinterval` and :func:`sys.setswitchinterval` instead.
+ (Contributed by Victor Stinner in :issue:`37392`.)
+
* The C function ``PyImport_Cleanup()`` has been removed. It was documented as:
"Empty the module table. For internal use only."
