mysqldump did not select the correct database before trying to dump
views from it. this resulted in an empty result set, which in turn
startled mysql-dump into a core-dump. this only happened for views,
not for tables, and was only visible with multiple databases that
weren't by sheer luck in the order mysqldump required, anyway. this
fixes by selecting the correct database before dumping views; it also
catches the empty set-condition if it should occur for other reasons.

(The above problem only occurs with -T -- create a separate file for
each table / view.) This ChangeSet results in correct output of view-
information while omitting the information for the view's stand-in
table. The rationale is that with -T, the user is likely interested
in transferring part of a database, not the db in its entirety (that
would be difficult as replay order is obscure, the files being named
for the table/view they contain rather than getting a sequence number).
'show create' works even on views that are short of a base-table (this
throw a warning though, like you would expect). Unfortunately, this is
not what mysqldump uses; it creates stand-in tables and hence requests
'show fields' on the view which fails with missing base-tables. The
--force option prevents the dump from stopping at this point; furthermore
this patch dumps a comment showing create for the offending view for
better diagnostics. This solution was confirmed by submitter as solving
their/clients' problem. Problem might become non-issue once mysqldump no
longer creates stand-in tables.
- Add new function 'ssl_verify_server_cert' which is used if we are
connecting to the server with SSL. It will compare the hostname in
the server's cert against the hostname that we used when connecting
to the server. Will reject the connection if hostname does not match.
- Add new option "OPT_SSL_VERIFY_SERVER_CERT" to be passed to mysql_options
which will turn on checking of servers cert.
- Add new argument "ssl-verify-server-cert" to all mysql* clients which
will activate the above option.
- Generate a new server cert with 1024 bits that has "localhost" as the server name.
The idea is to add DEFINER-clause in CREATE PROCEDURE and CREATE FUNCTION
statements. Almost all support of definer in stored routines had been already
done before this patch.
NOTE: this patch changes behaviour of dumping stored routines in mysqldump.
Before this patch, mysqldump did not dump DEFINER-clause for stored routines
and this was documented behaviour. In order to get full information about stored
routines, one should have dumped mysql.proc table. This patch changes this
behaviour, so that DEFINER-clause is dumped.
Since DEFINER-clause is not supported in CREATE PROCEDURE | FUNCTION statements
before this patch, the clause is covered by additional version-specific comments.
