Bug #76918 Unhelpful error for mysql_ssl_rsa_setup when datadir doesn't exist

Description:
When the datadir specified on the commandline for mysql_ssl_rsa_setup doesn't exist the error message is 'Failed to normalize the arguent for --datadir', which is not really helpful.

How to repeat:
mysql_ssl_rsa_setup --datadir=/etc/mysql/ssl --verbose
2015-05-03 13:01:14 [ERROR]   Failed to normalize the argument for --datadir: /etc/mysql/ssl

Suggested fix:
Generate a more helpful error message or try to create the directory if it doesn't exist yet.

Hello Daniël,

Thank you for the report.
Observed with 5.7.8/5.8.0 builds.

Thanks,
Umesh

Noted in 5.7.8, 5.8.0 changelogs.

When the directory specified for the secure_file_priv system variable
did not exist, the server produced a ""Failed to normalize the
argument" error message. It now produces a message indicating that
the directory did not exist. The same problem occurred for the
--datadir option to mysql_ssl_rsa_setup and was fixed the same way.
