This changeset adds support for
caching_sha2_passwordauthentication to add support for MySQL 8+. This authentication plugin is the default as of MySQL 8+ and is required to make the client work with MySQL 9+.This builds on top of the authentication plugin functionality added in #206. Prior to these changes, connecting to a server using
caching_sha2_passwordauthentication reported the following error:With these changes applied, connection now works successfully using
caching_sha2_passwordauthentication when requested. This means MySQL 5 and MySQL 8 and MySQL 9 should be supported just fine now.The affected code has 100% code coverage and has been tested against a number of MySQL server versions. The tests confirm it should continue to work for legacy servers not using authentication plugins or newer MySQL server versions using the existing
mysql_native_passwordauthentication or newercaching_sha2_passwordauthentication. We should probably follow-up on PR #196 to add more MySQL server versions to our test matrix, but I've kept this out of this PR to ease review.Marking this as WIP until the base functionality is merged via #206.Update: merged.Builds on top of #206 and others
