gh-90928: Improve static initialization of keywords tuple in AC (#95907) 2022-08-13 12:09:40 +02:00

gh-90928: Statically Initialize the Keywords Tuple in Clinic-Generated Code (gh-95860)
We only statically initialize for core code and builtin modules.  Extension modules still create
the tuple at runtime.  We'll solve that part of interpreter isolation separately.

This change includes generated code. The non-generated changes are in:

* Tools/clinic/clinic.py
* Python/getargs.c
* Include/cpython/modsupport.h
* Makefile.pre.in (re-generate global strings after running clinic)
* very minor tweaks to Modules/_codecsmodule.c and Python/Python-tokenize.c

All other changes are generated code (clinic, global strings).

bpo-18233: Add internal methods to access peer chain (GH-25467)
The internal `_ssl._SSLSocket` object now provides methods to retrieve
the peer cert chain and verified cert chain as a list of Certificate
objects. Certificate objects have methods to convert the cert to a dict,
PEM, or DER (ASN.1).

These are private APIs for now. There is a slim chance to stabilize the
approach and provide a public API for 3.10. Otherwise I'll provide a
stable API in 3.11.

bpo-43577: Fix deadlock with SSLContext._msg_callback and sni_callback (GH-24957)
OpenSSL copies the internal message callback from SSL_CTX->msg_callback to
SSL->msg_callback. SSL_set_SSL_CTX() does not update SSL->msg_callback
to use the callback value of the new context.

PySSL_set_context() now resets the callback and _PySSL_msg_callback()
resets thread state in error path.

bpo-34271: Add ssl debugging helpers (GH-10031)
The ssl module now can dump key material to a keylog file and trace TLS
protocol messages with a tracing callback. The default and stdlib
contexts also support SSLKEYLOGFILE env var.

The msg_callback and related enums are private members. The feature
is designed for internal debugging and not for end users.
