If anyone feels like it, it would be nice to update one of our CI jobs to use MySQL 8.

Fix unix socket check during caching_sha2_password
03ee36d 
The fact that conn->unix_socket is set does not mean that a Unix
socket is actually in use -- this member is set in a default
configuration.

Instead check whether a unix_socket stream ops is used.

Add support for caching_sha2_password in change user authentication

Same as for connection handshakes.

Handle error response during caching_sha2_password auth

In particular, this fixes handling of expired passwords.

Handle empty password fast path in caching_sha2_password
32cd373 
If an empty password is used, no additional packets are exchanged
during caching_sha2_password auth. We're only looking for an
OK/ERR response.

Re-commit MySQL 8 cached SHA auth support
4f06e67 
With changes to (hopefully) correctly fall back if OpenSSL support
is missing. Furthermore the hard-coded dependency on ext/hash is
no longer an issue, as this extension is required in master.

This reverts commit 63072e9, reversing
changes made to 4cbabb6.

Will this fix be incorporated into any version of PHP earlier than PHP 7.4?

@collegeman Given the mess that this was, support for caching_sha2_password will definitely not be backported to older PHP version.

Thanks @nikic. I blame Digital Ocean. I'm trying to migrate to their managed DB platform.

I'm on PHP 7.4.13 and I am still running into this. I get Access Denied and PHP only works after I login to the user at least once using mysql -u user -p

My password length is shorter than 20 (it's 15 characters.) and it only includes A-Z as a test. My MySQL version is 8.0.4

@nikic

Is there any reason this could still be happening? My extensions are pdo_mysql and mysqli

I upgrade my MySQL version from 8.0.4 to 8.0.22 and no longer have this problem. It appears the issue was from my MySQL version and not this bug, although I still find it weird how close it resembles this bug since it seems almost exactly the same.
