Subject: [PATCH 01/13]   Bug#15377 Valid multibyte sequences are truncated on
 INSERT ctype-euc_kr.c: ctype-gb2312.c:   Adding specific well_formed_length
 functions   for gb2312 and euckr, to allow storing characters   which are
 correct according to the character set   specifications but just don't have
 Unicode mapping.   Previously only those which have Unicode mapping   could
 be stored, while unassigned characters lead   to data truncation. Many files:

Subject: [PATCH 02/13]   Bug#15581: COALESCE function truncates mutli-byte
 TINYTEXT values field.cc:   BLOB variations have number-in-bytes limit,  
 unlike CHAR/VARCHAR which have number-of-characters limits.   A tinyblob
 column can store up to 255 bytes.   In the case of basic Latin letters (which
 use 1 byte per character)   we can store up to 255 characters in a tinyblob
 column.   When passing an utf8 tinyblob column as an argument into   a
 function (e.g. COALESCE) we need to reserve 3*255 bytes.   I.e. multiply
 length in bytes to mbcharlen for the character set.   Although in reality a
 tinyblob column can never be 3*255 bytes long,   we need to set max_length to
 multiply to make fix_length_and_dec()   of the function-caller (e.g.
 COALESCE) calculate the correct max_length   for the column being created.

ctype_utf8.result, ctype_utf8.test:
  Adding test case.

Subject: [PATCH 05/13] A fix for Bug#7209 "Client error with "Access Denied"
 on updates when high concurrency": remove HASH::current_record and make it an
 external search parameter, so that it can not be the cause of a race
 condition under high concurrent load. The bug was in a race condition in
 table_hash_search, when column_priv_hash.current_record was overwritten
 simultaneously by multiple threads, causing the search for a suitable grant
 record to fail. No test case as the bug is repeatable only under concurrent
 load.
