In 0804e97 we updated `github.com/go-sql-driver/mysql` to a pinned
commit (b4242bab7dc5) newer than the latest tagged release (v1.4.1) to
avoid needing to pull in an extra dep. that was removed since v1.4.1.
Unfortunately for reasons that are not perfectly clear updating
`github.com/google/certificate-transparency-go` is preferring v1.4.1
over the pseudo-version made from the commit newer than v1.4.1 that we
previously pinned.
Since there is movement on making a v1.5.0 go-sql-driver mysql release
tag and we can likely get ct-go to use that we'll temporarily accept
this downgrade to update ct-go.
Unit tests are confirmed to pass:
```
~/go/src/github.com/go-sql-driver/mysql$ git log --pretty=format:'%h' -n 1
72cd26f
~/go/src/github.com/go-sql-driver/mysql$ go test ./...
ok github.com/go-sql-driver/mysql 0.081s
```
The most recent tagged release of mysql is v1.4.1, from a year ago. It
also happens to pull in an unwanted dependency (appengine) that the
latest commit does not.
Tests pass:
$ go test -count=1 github.com/go-sql-driver/mysql
ok github.com/go-sql-driver/mysql 0.068s
Fixes#4530
This uses the mysql driver library's capability to use `SET` to set the system
variables that prefixdb previously was.
Unfortunately, the library doesn't sort the params when making the string, so we
have to do a little munging to TestNewDbMap.
Ran it in a checkout of the repo since godeps now doesn't include the test files (which is great!).
```
MYSQL_TEST_ADDR=127.0.0.1:3306 go test .
ok github.com/go-sql-driver/mysql 46.099s
```
This commit updates the `go-sql-driver` dependency to the tip of master
(665b83488b90b902ce0a305ef6652e599771cdf9).
A v1.3 release and a commitment to semantic versioning[0] will soon
allow us to switch this from master to a well defined tag.
