Mysql: could not use requested auth plugin '': this authentication plugin is not supported

I'm seeing a similar problem, although with a different plugin that apparently cannot be used.

[mysql] 2018/07/02 17:10:36 driver.go:120: could not use requested auth plugin 'mysql_native_password': this user requires mysql native password authentication.

The change appears to have been introduced by affd4c93966fe80839dc3dd720440aaad00914b9, as earlier revisions have no such problem despite no changes to the server or the client code. I also noticed this when upgrading from 1.3.0 to 1.4.0.

Server version: mysql:5.7 docker image
Go version: go version go1.10 linux/amd64

Same issue for Server version: 5.1.66-0+squeeze1-log

https://github.com/go-sql-driver/mysql/blob/master/packets.go#L236

returns an empty plugin which causes the warning

There was another issue on this topic about a month ago. This is already closed, even though I do not think that the discussion has produced any result. There is a separate branch created by @julienschmidt that has solved the problem, at least in my case. Maybe you can try if that branch works for you too.

Go version: go version go1.9.6 linux/amd64
Server version: 5.1.73
Server OS: centos-release-6-9

This branch solved it for me. Would it be merged to master?

go version go1.10.2 windows/amd64
Server version: 5.1.66-0+squeeze1-log

I encounter this problem again -_- !。why not merge this fixed to master?

Opened a pull request for that branch: #835
