Linter fixes. * isort * Cleanup, store server name for later use. Add RSA ciphers. Log rejected SNIs. * Cleanup, linter. * Alter the order of initial log messages and handling. In particular, enable debug mode early so that debug messages during init can be shown. * Store server name (SNI) to conn_info. * Update test with new error message. * Refactor for readability. * Cleanup * Replace old expired test cert with new ones and a script for regenerating them as needed. * Refactor TLS tests to a separate file. * Add cryptography to dev deps for rebuilding TLS certs. * Minor adjustment to messages. * Tests added for new TLS code. * Find the correct log row before testing for message. The order was different on CI. * More log message order fixup. The tests do not account for the logo being printed first. * Another attempt at log message indexing fixup. * Major TLS refactoring. CertSelector now allows dicts and SSLContext within its list. Server names are stored even when no list is used. SSLContext.sanic now contains a dict with any setting passed and information extracted from cert. That information is available on request.conn_info.cert. Type annotations added. More tests incl. a handler for faking hostname in tests. * Remove a problematic logger test that apparently was not adding any coverage or value to anything. * Revert accidental commit of uvloop disable. * Typing fixes / refactoring. * Additional test for cert selection. Certs recreated without DNS:localhost on sanic.example cert. * Add tests for single certificate path shorthand and SNI information. * Move TLS dict processing to CertSimple, make the names field optional and use names from the cert if absent. * Sanic CLI options --tls and --tls-strict-host to use the new features. * SSL argument typing updated * Use ValueError for internal message passing to avoid CertificateError's odd message formatting. * Linter * Test CLI TLS options. * Maybe the right codeclimate option now... * Improved TLS argument help, removed support for combining --cert/--key with --tls. * Removed support for strict checking without any certs, black forced fscked up formatting. * Update CLI tests for stricter TLS options.

Administratively merging because @vltr and @ahopkins are the release managers, and @ahopkins is originator of the PR * Add Python 3.10 testing (and support) * fixed py310 tox environment for windows, quoted '3.10' in python-310 tests to avoid numeric compression * updated tox.ini for py310 * quoted the rest of the bare 3.10 references in the workflows * Issue with pytest requires version bump to

This makes new connections without any request obey keepalive timeout rather than request timeout like they currently do. * Revert typo * Remove request timeout endpoint test which is no longer working (still tested by mocking).
