MySQL 5.5.42 Overview and Highlights
+0 Vote Up -0Vote Down

MySQL 5.5.42 was recently released (it is the latest MySQL 5.5, is GA), and is available for download here:

http://dev.mysql.com/downloads/mysql/5.5.html

This release, similar to the last 5.5 release, is mostly uneventful.

There were only 3 “Functionality Added or Changed” bugs this time, all related to SSL, and only 9 bugs overall fixed.

Out of the 9 bugs, there were 2 InnoDB bugs, and 1 replication bug, all of which seemed rather minor or obscure. Here are the ones worth noting:

  • Support for the SSL 2.0 and SSL 3.0 protocols has …

How to test if CVE-2015-0204 FREAK SSL security flaw affects you
+0 Vote Up -0Vote Down

The CVE-2015-0204 FREAK SSL vulnerability abuses intentionally weak “EXPORT” ciphers which could be used to perform a transparent Man In The Middle attack. (We seem to be continually bombarded with not only SSL vulnerabilities but the need to name vulnerabilities with increasing odd names.)

Is your server vulnerable?

This can be tested using the following GIST

If the result is 0; the server is not providing the EXPORT cipher; and as such is not vulnerable.

Is your client vulnerable? …

Using Master-Master for failover? :(
+0 Vote Up -0Vote Down

Using master-master for MySQL? To be frankly we need to get rid of that architecture. We are skipping the active-active setup and show why master-master even for failover reasons is the wrong decision.

So why does a DBA thinks master-master is good for in a failover scenario?

  • The recovered node does get his data automatically.
  • You need not to use a backup for recovery.

Please remember: MySQL Replication is async

Again: MySQL Replication is async. Even the so called semi-sync Replication!

So following is quite likely.

See a nice master-master …

Heartbeat Inclusion Protocol Handling in MySQL Cluster
Employee +1 Vote Up -0Vote Down

The below description was added to the MySQL Cluster 7.4 source code
and describes how new nodes are added into the heartbeat protocol at
startup of a node.

The protocol to include our node in the heartbeat protocol starts when
we call execCM_INFOCONF. We start by opening communication to all nodes
in the cluster. When we start this protocol we don't know anything about
which nodes are up and running and we don't which node is currently the
president of the heartbeat protocol.

For us to be successful with being included in the heartbeat protocol we
need to be …
