Description Remi Collet 2011-05-09 15:13:03 UTC
Version-Release number of selected component (if applicable):
mysql-5.5.10-2.fc15.x86_64
perl-DBD-MySQL-4.018-5.fc15.x86_64


Steps to Reproduce:
1. mysqlhotcopy -p=<secret> test test2

From DBD_MySQL source code

        case SQL_IDENTIFIER_QUOTE_CHAR:
            /*XXX What about a DB started in ANSI mode? */
            /* Swiped from MyODBC's get_info.c */
            using_322=is_prefix(mysql_get_server_info(imp_dbh->pmysql),"3.22");
            retsv = newSVpv(!using_322 ? "`" : " ", 1);
            break;

The is_prefix function, defined in strings/is_prefix.c is not exported from latest MySQL build.

Comment 1 Remi Collet 2011-05-09 15:14:52 UTC
Adding Tom Lane in CC: because this "could" be fixed in mysql package.

But, probably a better solution should be to not used this function which is not in the offical MySQL client API.

Comment 2 Tom Lane 2011-05-09 15:33:55 UTC
Yes, this is exactly the sort of gratuitous dependency on not-officially-exported internals of libmysqlclient that I was trying to get rid of by installing a symbol filter.  Please change that code to use strncmp() or some such instead.

(Or you could consider dropping support for mysql 3.x altogether; surely that hasn't been seen in the wild for some time ...)
