Problem

From a given install (tarball, RPM, DEB) you only have the version information available, not the GitHash the binaries were built from.

Solution

Compile the following into the binaries

• GitHash the build was from
• Buildbot build number

This info should be available as

• system variable (e.g. VERSION_GITHASH) - Must
• from output of 'mysql -v' (but that's just the githash of mysql and not mysqld) - Should
• from output of 'mysqld --verbose --help' - Must

Rationale

Supportability. Given a random build a user may have, there is no simple mechanism to track back to the GitHash of the commit the code was built with. This is especially important for anybody with a custom build (e.g. feature testing, customer patch etc.).

Workaround

None
