Bug#41728: Dropped symbol but no soname change
Restore a stub of the removed mysql_odbc_escape_string function to fix a ABI breakage. The function was intended to be private and used only by Connector/ODBC, but, unfortunately, it was exported as part of the ABI. Nonetheless, only a stub is restored as the original function is inherently broken and shouldn't be used. This restoration only applies to MySQL 5.0. This will be addressed differently in later versions -- reworked library versioning. include/mysql.h: Restore mysql_odbc_escape_string prototype. include/mysql_h.ic: Update ABI check. libmysql/libmysql.c: Restore a mysql_odbc_escape_string stub. libmysql/libmysql.def: Restore mysql_odbc_escape_string. libmysqld/libmysqld.def: Restore mysql_odbc_escape_string.
