      Bug #40761: Assert on sum function on · ce8ad64d
      Gleb Shchepa authored
                  IF(..., CAST(longtext AS UNSIGNED), signed_val)
                  (was: LEFT JOIN on inline view crashes server)
      
      Select from a LONGTEXT column wrapped with an expression
      like "IF(..., CAST(longtext_column AS UNSIGNED), smth_signed)"
      failed an assertion or crashed the server. IFNULL function was
      affected too.
      
      LONGTEXT column item has a maximum length of 32^2-1 bytes,
      at the same time this is a maximum possible length of any
      MySQL item. CAST(longtext_column AS UNSIGNED) returns some
      unsigned numeric result of length 32^2-1, so the result of
      IF/IFNULL function of this number and some other signed number
      will have text length of (32^2-1)+1=32^2 (one byte for the
      minus sign) - there is integer overflow, and the length is
      equal to zero. That caused assert/crash.
      
      The bug has been fixed by the same solution as in the CASE
      function implementation.

      Bug#33812: mysql client incorrectly parsing DELIMITER · cf9126a0
      Chad MILLER authored
      Fix parsing of mysql client commands, especially in relation to
      single-line comments when --comments was specified.
      
      This is a little tricky, because we need to allow single-line
      comments in the middle of statements, but we don't want to allow
      client commands in the middle of statements. So in
      comment-preservation mode, we go ahead and send single-line
      comments to the server immediately when we encounter them on their
      own. 
      
      This is still slightly flawed, in that it does not handle a
      single-line comment with leading spaces, followed by a client-side
      command when --comment has been enabled. But this isn't a new
      problem, and it is quite an edge condition. Fixing it would require
      a more extensive overall of how the mysql client parses commands.

      Bug #33420 Test 'rpl_packet' fails randomly with changed "Exec_Master_Log_Pos" · cea55f3d
      Andrei Elkin authored
      Bug #41173 rpl_packet fails sporadically on pushbuild: query 'DROP TABLE t1' failed
      
      
      The both issues appeared to be a race between the SQL thread executing CREATE table t1
      and the IO thread that is expected to stop at the consequent big size event.
      The two events need serialization which is implemented.
      The early bug required back-porting a part fixes for bug#38350 exclusively for 5.0 version.

      BUG#38826 Race in MYSQL_LOG::purge_logs is impossible to debug in production · 5726574b
      Luis Soares authored
      BUG#39325 Server crash inside MYSQL_LOG::purge_first_log halts replicaiton
      
      The patch reverses the order of the purging and updating events for log and relay-log.info/index files respectively.
      This solves the problem of having holes caused by crashes happening between updating info/index files and purging logs.
      
      NOTE: This is a combined patch for BUG#38826 and BUG#39325. This patch is based on bugteam tree and takes into account reviewers suggestions.
