It would be nice to add a memory_limit feature to the tracemalloc to make memory allocation fails if it would make the traced memory greater than the limit. See also the pyfailmalloc project which is similar but different: https://bitbucket.org/haypo/pyfailmalloc pyfailmalloc doesn't count allocated bytes, it schedules an error in N allocations where N is a random number. And pyfailmalloc only schedules one error, whereas I propose to make all memory allocations fails until the limit is respected. So if you only 0 bytes free (according to the limit), all memory allocations fail until some bytes are freed. Python currently behaves badly under very low memory condition. See also the issue #19437. |

This feature cannot be used without a reliable PyErr_NoMemory(): I add issue #19835 as a dependency. |

test_limit.patch: Patch to test the memory_limit on the Python test suite. tracemalloc_memory_limit-2.patch and unittest_leak.patch (of issue #19880) are required to test it. |
