      Bug#36579 Dumping information about locks in use may lead to a server crash · 1ee4a3ac
      Davi Arnaut authored
      Dumping information about locks in use by sending a SIGHUP signal
      to the server or by invoking the "mysqladmin debug" command may
      lead to a server crash in debug builds or to undefined behavior in
      production builds.
      
      The problem was that a mutex that protects a lock object (THR_LOCK)
      might have been destroyed before the lock object was actually removed
      from the list of locks in use, causing a race condition with other
      threads iterating over the list. The solution is to destroy the mutex
      only after removing lock object from the list.
      
      mysys/thr_lock.c:
        Destroy the mutex that protects the lock object only after removing
        the lock object from the list of locks in use.

      Bug#37301 Length and Max_length differ with no obvious reason(2nd version) · 21598ea0

      Length value is the length of the field,

      Bug#38195: Incorrect handling of aggregate functions when loose index scan is · b789b4f3
      Evgeny Potemkin authored
      used causes server crash.
      
      When the loose index scan access method is used values of aggregated functions
      are precomputed by it. Aggregation of such functions shouldn't be performed
      in this case and functions should be treated as normal ones.
      The create_tmp_table function wasn't taking this into account and this led to
      a crash if a query has MIN/MAX aggregate functions and employs temporary table
      and loose index scan.
      Now the JOIN::exec and the create_tmp_table functions treat MIN/MAX aggregate
      functions as normal ones when the loose index scan is used.

      Bug#38296 (low memory crash with many conditions in a query) · e04dfffb
      Marc Alff authored
      This fix is for 5.0 only : back porting the 6.0 patch manually
      
      The parser code in sql/sql_yacc.yy needs to be more robust to out of
      memory conditions, so that when parsing a query fails due to OOM,
      the thread gracefully returns an error.
      
      Before this fix, a new/alloc returning NULL could:
      - cause a crash, if dereferencing the NULL pointer,
      - produce a corrupted parsed tree, containing NULL nodes,
      - alter the semantic of a query, by silently dropping token values or nodes
      
      With this fix:
      - C++ constructors are *not* executed with a NULL "this" pointer
      when operator new fails.
      This is achieved by declaring "operator new" with a "throw ()" clause,
      so that a failed new gracefully returns NULL on OOM conditions.
      
      - calls to new/alloc are tested for a NULL result,
      
      - The thread diagnostic area is set to an error status when OOM occurs.
      This ensures that a request failing in the server properly returns an
      ER_OUT_OF_RESOURCES error to the client.
      
      - OOM conditions cause the parser to stop immediately (MYSQL_YYABORT).
      This prevents causing further crashes when using a partially built parsed
      tree in further rules in the parser.
      
      No test scripts are provided, since automating OOM failures is not
      instrumented in the server.
      Tested under the debugger, to verify that an error in alloc_root cause the
      thread to returns gracefully all the way to the client application, with
      an ER_OUT_OF_RESOURCES error.
