# BUG#37426: RBR breaks for CHAR() UTF8 fields > 85 chars
#
# We have 4 combinations to test with respect to the field length
# (i.e., the number of bytes) of the CHAR fields:
#
# 1. Replicating from CHAR<256 to CHAR<256
# 2. Replicating from CHAR<256 to CHAR>255
# 3. Replicating from CHAR>255 to CHAR<256
# 4. Replicating from CHAR>255 to CHAR>255
# We also make a special case of using the max size of a field on the
# master, i.e. CHAR(255) in UTF-8, giving another three cases.
#
# 5. Replicating UTF-8 CHAR(255) to CHAR(<256)
# 6. Replicating UTF-8 CHAR(255) to CHAR(>255)
# 7. Replicating UTF-8 CHAR(255) to CHAR(255) UTF-8

@note In order to be able to handle lengths exceeding 255 and be
backwards-compatible with pre-5.1.26 servers, an extra two bits of
the length has been added to the metadata in such a way that if
they are set, a new unrecognized type is generated. This will
cause pre-5.1-26 servers to stop due to a field type mismatch,
while new servers will be able to extract the extra bits. If the
length is <256, there will be no difference and both a new and an
old server will be able to handle it.
@note The extra two bits are added to bits 13 and 14 of the
parameter data (with 1 being the least siginficant bit and 16 the
most significant bit of the word) by xoring the extra length bits
with the real type. Since all allowable types have 0xF as most
significant bits of the metadata word, lengths <256 will not affect
the real type at all, while all other values will result in a
non-existant type in the range 17-244.
