BUG#11338 (logging of prepared statement w/ blob type)
In cp932, '\' character can be the second byte in a
multi-byte character stream. This makes it difficult to use
mysql_escape_string. Added flag to indicate which languages allow
'\' as second byte of multibyte sequence so that when putting a prepared
statement into the binlog we can decide at runtime whether hex encoding
is really needed.
include/m_ctype.h:
Added bool to indicate character sets which allow '\' as the second
byte of a multibyte character set (currently only cp932). For these
character sets, escaping with '\' is dangerous and leads to corruption
in replication.
include/my_sys.h:
Add function to enocde a string as hex with no prefix (bare)
mysys/charset.c:
Add function to encode string as hex with no prefix (bare).
sql/item.cc:
Check the connection character set to see if escape_string_for_mysql
is safe, or if character set requires unambiguous (hex) encoding
sql/item.h:
Pass thd to query_val_str for access to charset()
sql/sql_prepare.cc:
Pass thd to query_val_str.
strings/ctype-big5.c:
Add escape_with_backslash_is_dangerous flag.
