A code review comment for Bug#52289.
Encapsulate the deadlock detection functionality into
a visitor class...

Remove a race introduced by omission: 
initialize iterators under a read lock on the object.

Encapsulate the deadlock detection functionality into 
a visitor class, and separate it from the wait-for graph
traversal code.

Use "Internal iterator" and "Visitor" patterns to 
achieve the desired separation of responsibilities.

Add comments.

and methods.

transactional SELECT and ALTER TABLE ...  REBUILD PARTITION".

Make open flags part of Open_table_context.
This allows to simplify some code and (in future)
enforce the invariant that we don't, say, request a back 
off on the table when there is MYSQL_OPEN_IGNORE_FLUSH 
flag.

 transactional SELECT and ALTER TABLE ...  REBUILD PARTITION".

Move declarations of sql_base.cc classes to sql_base.h
(previously declared in sql_class.h).
Became possible after a header file split.

transactional SELECT and ALTER TABLE ...  REBUILD PARTITION".

Remove unused code - TL_WRITE_ALLOW_READ thr_lock.c lock.

Fix various mismatches between function's language linkage. Any
particular function that is declared in C++ but should be callable
from C must have C linkage. Note that function types with different
linkages are also distinct. Thus, if a function type is declared in
C code, it will have C linkage (same if declared in a extern "C"
block).

merge of patch for bug#52913 from 5.1-bugteam to trunk-bugfixing. Changed $basedir to $bindir in mysql-test-run.pl.

      Problems:
      - regression (compating to version 5.1) in metadata for BLOB types
      - inconsistency between length metadata in server and embedded for BLOB types
      - wrong max_length calculation in items derived from BLOB columns
     @ libmysqld/lib_sql.cc
        Calculating length metadata in embedded similary to server version,
        using new function char_to_byte_length_safe().

errors
            
In the fix of BUG#39934 in 5.1-rep+3, errors are generated when
binlog_format=row and a statement modifies a table restricted to
statement-logging (ER_BINLOG_ROW_MODE_AND_STMT_ENGINE); or if
binlog_format=statement and a statement modifies a table restricted to
row-logging (ER_BINLOG_STMT_MODE_AND_ROW_ENGINE).
            
However, some DDL statements that lock tables (e.g. ALTER TABLE,
CREATE INDEX and CREATE TRIGGER) were causing spurious errors,
although no row might be inserted into the binary log.
            
To fix the problem, we tagged statements that may generate
rows into the binary log and thence the warning messages are
only printed out when the appropriate conditions hold and rows
might be changed.

- Ported relevant changes from the upstream version to not
break strict-aliasing rules and to fix compiler warnings and
and infinite loops caused by that issue.

- Fixed compilation with Honor_FLT_ROUNDS defined.

- Fixed an unused variable warning.

breaks
      
When a "CREATE TEMPORARY TABLE SELECT * FROM" was executed the OPTION_KEEP_LOG was
not set into the thd->variables.option_bits. For that reason, if the transaction
had updated only transactional engines and was rolled back at the end (.e.g due to
a deadlock) the changes were not written to the binary log, including the creation
of the temporary table.
      
To fix the problem, we have set the OPTION_KEEP_LOG into the
thd->variables.option_bits when a "CREATE TEMPORARY TABLE
SELECT * FROM" is executed.
