* bpo-43880: Show DeprecationWarnings for deprecated ssl module features ↵Christian Heimes2021-04-1914-201/+305

* bpo-42854: Use SSL_read/write_ex() (GH-25468)Christian Heimes2021-04-194-18/+34
| | | | | | | | The ssl module now uses ``SSL_read_ex`` and ``SSL_write_ex`` internally. The functions support reading and writing of data larger than 2 GB. Writing zero-length data no longer fails with a protocol violation error. Signed-off-by: Christian Heimes <christian@python.org>
* bpo-36076: Add SNI support to ssl.get_server_certificate. (GH-16820)juhovh2021-04-184-2/+28
| | | | | | | | | | | | | | Many servers in the cloud environment require SNI to be used during the SSL/TLS handshake, therefore it is not possible to fetch their certificates using the ssl.get_server_certificate interface. This change adds an additional optional hostname argument that can be used to set the SNI. Note that it is intentionally a separate argument instead of using the host part of the addr tuple, because one might want to explicitly fetch the default certificate or fetch a certificate from a specific IP address with the specified SNI hostname. A separate argument also works better for backwards compatibility. Automerge-Triggered-By: GH:tiran

* bpo-43362: Fix invalid free and return check in _sha3 module (GH-25463)Christian Heimes2021-04-182-3/+11
| | | | | | | | | | | Commit 93d50a6a8d0c5d332c11aef267e66573a09765ac / GH-21855 changed the order of variable definitions, which introduced a potential invalid free bug. Py_buffer object is now initialized earlier and the result of Keccak initialize is verified.

* bpo-41282: (PEP 632) Load install schemes from sysconfig (GH-24549)Lumír 'Frenzy' Balhar2021-04-143-38/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With this patch, `distutils.command.install.INSTALL_SCHEMES` are loaded from `sysconfig._INSTALL_SCHEMES`. The distutils module is deprecated and will be removed in 3.12 (PEP 632). This change makes the `sysconfig._INSTALL_SCHEMES` the single point of truth for install schemes while keeping `distutils.command.install.INSTALL_SCHEMES` exactly the same. If we, during the transition to the sysconfig, change something, this makes sure that it also propagates to distutils until the module gets removed. Moreover, as discussed [on Discourse], Linux distros need to patch distutils/sysconfig to make sure the packages will land in proper locations. This patch makes it easier because it leaves only one location where install schemes are defined which is much easier to patch/adjust. [on Discourse]: https://discuss.python.org/t/pep-632-deprecate-distutils-module/5134 The implementation is slightly different than the plan but I think it's the easiest way how to do it and it also makes the downstream patch simple, flexible and easy to maintain. It's also necessary to implement this before setuptools starts bundling the distutils module so the default install schemes stay in the standard library. The removed code from sysconfig does not seem to have any negative effect because, honestly, it seems that nothing actually uses the install schemes from sysconfig at all. There were many big changes in these modules where they were trying to include packaging in stdlib and then reverted that. Also, the test of distutils install command does not count with the different locations which is good evidence that the reason to have this piece of code is no longer valid. https://bugs.python.org/issue41282
