[issue35291] duplicate of memoryview from io.BufferedWriter leaks

New submission from Jason Madden : Using Python 2.7.15, if a BufferedWriter wraps an IO object that duplicates the memoryview passed to the IO object's `write` method, that memoryview leaks. This script demonstrates the problem by leaking a memoryview for each iteration of the loop (i

[issue33005] 3.7.0b2 Interpreter crash in dev mode (or with PYTHONMALLOC=debug) with 'python -X dev -c 'import os; os.fork()'

New submission from Jason Madden : At the request of Victor Stinner on twitter, I ran the gevent test suite with Python 3.7.0b2 with the new '-X dev' argument and discovered an interpreter crash. With a bit of work, it boiled down to a very simple command: $ env -i .runtime

[issue24291] wsgiref.handlers.SimpleHandler truncates large output blobs

Jason Madden added the comment: gevent has another simple reproducer for this. I do believe it's not gevent's fault, the fault is in the standard library; SimpleHandler._write needs to loop until `sent += self.stdeout.write(data)` is `len(data)`. I have written up more on this

[issue24291] wsgiref.handlers.SimpleHandler truncates large output blobs

Jason Madden added the comment: Django uses a `wsgiref.simple_server` to serve requests, which in turn uses `socketserver.StreamRequestHandler` to implement its `WSGIRequestHandler`. That base class explicitly turns off buffering for writes (`wbufsize = 0` is the class default which gets

[issue24291] wsgiref.handlers.SimpleHandler truncates large output blobs

Jason Madden added the comment: Is there an expected `self.stdout` implementation that doesn't return the number of bytes it writes? `sys.stdout` does, as does `io.RawIOBase`. It doesn't seem clear to me that practically speaking there's a compatibility problem with req

[issue24291] wsgiref.handlers.SimpleHandler truncates large output blobs

Jason Madden added the comment: `self.stdin` and `self.stderr` are documented to be `wsgi.input` and `wsgi.errors`, which are both described as "file-like" objects, meaning that the `write` method should return bytes written. It seems like the same could reasonably be said to b

[issue24291] wsgiref.handlers.SimpleHandler truncates large output blobs

Jason Madden added the comment: I'm sorry, I'm still not following the argument that `write` is likely to return nothing. `RawIOBase` and `BufferedIOBase` both document that `write` must return the number of written bytes; if you don't return that, you break anything that ass
