Changes in MySQL 5.6.33 (2016-09-06)

Test Suite Notes
----------------
In mysql-test-run.pl, a limit of 50 was imposed on the number of workers for \ 
parallel testing, which on systems with more than 50 CPUs resulted in exhaustion \ 
of unique thread IDs. The ID-exhaustion problem has been corrected, and the \ 
limit of 50 on number of workers has been lifted. Thanks to Daniel Black for the \ 
patch on which this change was based. Additionally, these changes were made:

To avoid idle workers, the number of parallel workers now is limited to the \ 
number of tests.

Previously, if --parallel=auto was given and the MTR_MAX_PARALLEL environment \ 
variable was not set, a limit of 8 was imposed on the number of parallel \ 
workers. This limit has been lifted.

(Bug 22342399, Bug 79585)

Functionality Added or Changed
------------------------------
CMake support for compiling with Solaris Studio 12.5 was added. (Bug 82249, Bug \ 
24303829, Bug 81274, Bug 23212938)

Bugs Fixed
----------
InnoDB: An operation that dropped and created a full-text search table raised an \ 
assertion. (Bug 24315031)

InnoDB: Accessing full-text search auxiliary tables while dropping the indexed \ 
table raised an assertion. (Bug 24009272)

InnoDB: An online DDL operation on a table with indexed BLOB columns raised an \ 
assertion during logging of table modifications. (Bug 23760086)

Replication: mysqlbinlog --read-from-remote-server log1 log2 was opening a new \ 
connection for log2 without freeing the connection used for log1. Thanks to \ 
Laurynas Biveinis for the contribution. (Bug 81675, Bug 23540182)

Replication: With binlog_row_image=FULL, when updating single tables temporary \ 
tables were unnecessarily being used. The fix ensures single table update \ 
follows the same pattern as multi-table update. (Bug 79867, Bug 22510353)

For mysqld_safe, the argument to --malloc-lib now must be one of the directories \ 
/usr/lib, /usr/lib64, /usr/lib/i386-linux-gnu, or /usr/lib/x86_64-linux-gnu. In \ 
addition, the --mysqld and --mysqld-version options can be used only on the \ 
command line and not in an option file. (Bug 24464380)

It was possible to write log files ending with .ini or .cnf that later could be \ 
parsed as option files. The general query log and slow query log can no longer \ 
be written to a file ending with .ini or .cnf. (Bug 24388753)

Privilege escalation was possible by exploiting the way REPAIR TABLE used \ 
temporary files. (Bug 24388746)

If the basedir system variable was set at server startup from the command line \ 
or option file, the value was not normalized (on Windows, / was not replaced \ 
with /). (Bug 23747899, Bug 82125)

In-place ALTER TABLE operations which when executed separately caused no table \ 
rebuild could when combined into a single statement result in a table rebuild. \ 
(Bug 23475211, Bug 81587)

A blank server name in CREATE SERVER statements produced a server exit rather \ 
than an error. (Bug 23295288)

A prepared statement that used a parameter in the select list of a derived table \ 
that was part of a join could cause a server exit. (Bug 22392374, Bug 24380263)

MEDIUMINT columns used in operations with long integer values could result in \ 
buffer overflow. (Bug 19984392)

A spurious ER_NO_SUCH_TABLE error could occur when attempting to execute a \ 
prepared CREATE TABLE ... SELECT statement that used a temporary table in the \ 
FROM clause and called a stored function. The same error could occur for a \ 
nonprepared version of the statement if used in a stored procedure when the \ 
procedure was re-executed. (Bug 16672723, Bug 68972)

EINTR handling in the client library has been fixed so that interrupted read and \ 
write calls are retried. Previously, EINTR was ignored. (Bug 82019, Bug \ 
23703570)
