I think this warning actually happens everywhere, but because of
how it happens, it gets masked by older versions of Perl.
Basically, Cxn's DESTROY method checks if $self->{dbh}, and if true,
calls ->disconnect on that. However, during global destruction --
when DESTROY is called -- you have no assurances that DESTROY
will be called before the dbh was already reaped.
This commit makes sure that the $self->{dbh} we have inside DESTROY
is actually a reference.
Percona Toolkit =============== Percona Toolkit is a collection of advanced command-line tools used by Percona (http://www.percona.com/) support staff to perform a variety of MySQL and system tasks that are too difficult or complex to perform manually. These tools are ideal alternatives to private or "one-off" scripts because they are professionally developed, formally tested, and fully documented. They are also fully self-contained, so installation is quick and easy and no libraries are installed. Percona Toolkit is developed and supported by Percona Inc. For more information and other free, open-source software developed by Percona, visit http://www.percona.com/software/. Installing ---------- To install all tools, run: perl Makefile.PL make make test make install You probably need to be root to `make install'. On most systems, the tools are installed in /usr/local/bin. See the INSTALL file for more information. Documentation ------------- Run `man percona-toolkit' to see a list of installed tools, then `man tool' to read the embedded documentation for a specific tool. You can also read the documentation online at http://www.percona.com/software/percona-toolkit/.
