* GH-95494: Fix transport EOF handling in OpenSSL 3.0 (GH-95495)David Benjamin2023-03-223-7/+32
| | | | | | | | | | | | | | | | | | | | | GH-25309 enabled SSL_OP_IGNORE_UNEXPECTED_EOF by default, with a comment that it restores OpenSSL 1.1.1 behavior, but this wasn't quite right. That option causes OpenSSL to treat transport EOF as the same as close_notify (i.e. SSL_ERROR_ZERO_RETURN), whereas Python actually has distinct SSLEOFError and SSLZeroReturnError exceptions. (The latter is usually mapped to a zero return from read.) In OpenSSL 1.1.1, the ssl module would raise them for transport EOF and close_notify, respectively. In OpenSSL 3.0, both act like close_notify. Fix this by, instead, just detecting SSL_R_UNEXPECTED_EOF_WHILE_READING and mapping that to the other exception type. There doesn't seem to have been any unit test of this error, so fill in the missing one. This had to be done with the BIO path because it's actually slightly tricky to simulate a transport EOF with Python's fd based APIs. (If you instruct the server to close the socket, it gets confused, probably because the server's SSL object is still referencing the now dead fd?)

* gh-94673: Isolate the _io module to Each Interpreter (gh-102663)Eric Snow2023-03-212-12/+40
| | | | | Aside from sys and builtins, _io is the only core builtin module that hasn't been ported to multi-phase init. We may do so later (e.g. gh-101948), but in the meantime we must at least take care of the module's static types properly. (This came up while working on gh-101660.) https://github.com/python/cpython/issues/94673

* gh-98608: Fix Failure-handling in new_interpreter() (gh-102658)Eric Snow2023-03-211-1/+1
| | | | | The error-handling code in new_interpreter() has been broken for a while. We hadn't noticed because those code mostly doesn't fail. (I noticed while working on gh-101660.) The problem is that we try to clear/delete the newly-created thread/interpreter using itself, which just failed. The solution is to switch back to the calling thread state first. https://github.com/python/cpython/issues/98608

* gh-102304: Move the Total Refcount to PyInterpreterState (gh-102545)Eric Snow2023-03-2113-40/+117
| | | | | Moving it valuable with a per-interpreter GIL. However, it is also useful without one, since it allows us to identify refleaks within a single interpreter or where references are escaping an interpreter. This becomes more important as we move the obmalloc state to PyInterpreterState. https://github.com/python/cpython/issues/102304

* gh-98608: Stop Treating All Errors from _Py_NewInterpreterFromConfig() as ↵Eric Snow2023-03-216-17/+27
| | | | | | | Fatal (gh-102657) Prior to this change, errors in _Py_NewInterpreterFromConfig() were always fatal. Instead, callers should be able to handle such errors and keep going. That's what this change supports. (This was an oversight in the original implementation of _Py_NewInterpreterFromConfig().) Note that the existing [fatal] behavior of the public Py_NewInterpreter() is preserved. https://github.com/python/cpython/issues/98608

| | | | | | | The essentially eliminates the global variable, with the associated benefits. This is also a precursor to isolating this bit of state to PyInterpreterState.
