New submission from Amaury Forgeot d'Arc <[EMAIL PROTECTED]>:
Two problems with memoryview:
- The buffer interface of memoryview leaks a reference:
str(memoryview(b'text'), 'utf-8')
- memoryview does not implement tp_traverse and tp_clear, so reference
cycle cannot be collected, as with:
import gc
class MyBuf(bytes): pass
def f():
buf = MyBuf(b'abc')
m = memoryview(buf)
buf.m = m
gc.collect();gc.collect();gc.collect()
each call to f() leaks 6 references.
