Changes in MySQL NDB Cluster 7.2.27 (5.5.54-ndb-7.2.27) (2017-01-17)

MySQL NDB Cluster 7.2.27 is a new release of NDB Cluster,
incorporating new features in the NDB storage engine, and
fixing recently discovered bugs in previous MySQL NDB Cluster
7.2 development releases.

Obtaining MySQL NDB Cluster 7.2. MySQL NDB Cluster 7.2
source code and binaries can be obtained from
http://dev.mysql.com/downloads/cluster/.

This release also incorporates all bugfixes and changes made
in previous NDB Cluster releases, as well as all bugfixes and
feature changes which were added in mainline MySQL 5.5
through MySQL 5.5.54 (see Changes in MySQL 5.5.54
(2016-12-12, General availability)
(http://dev.mysql.com/doc/relnotes/mysql/5.5/en/news-5-5-54.html)).

Bugs Fixed

* A number of potential buffer overflow issues were found
and fixed in the NDB codebase. (Bug #25260091)
References: See also: Bug #23152979.

* ndb_restore did not restore tables having more than 341
columns correctly. This was due to the fact that the
buffer used to hold table metadata read from .ctl files
was of insufficient size, so that only part of the table
descriptor could be read from it in such cases. This
issue is fixed by increasing the size of the buffer used
by ndb_restore for file reads. (Bug #25182956)
