- Adding a class Lex_ident_fs, to store identifiers for on-disk
database objects, such as databases, tables, triggers.
- Moving the validation code from check_db_name()
to non-modifying methods in Lex_ident_fs:
Lex_ident_fs::check_body()
Lex_ident_fs::check_db_name()
Adding a new method Lex_ident_fs::check_db_name_with_error(),
which performs validation and raises an error on validation failure.
Unlike the old function check_db_name(), the new class Lex_ident_fs
does not lower-case the identifier during the validation.
Lower-casing must be done before calling Lex_ident_fs validation methods.
- Adding a low level helper template class CharBuffer which can:
* store exact or lower-cased strings with a short fixed maximum length
* return the value as a LEX_CSTRING efficiently
- Adding a helper template class DBNameBuffer (deriving from CharBuffer), to
allocate optionally lower-cased database identifiers on stack when relevant.
Useful for temporary values which don't need to be allocated on MEM_ROOT.
- Using DBNameBuffer in mysql_change_db()
- Using DBNameBuffer in show_create_db()
Tests with checking metadata or that cannot be run with
the view-protocol are excluded from --view-protocol.
For tests that do not allow the use of an additional connection,
the util connection is disabled with "--disable_service_connection".
Also cases with bugs for --view-protocol are disabled.
