Changes in MySQL Connector/Python 2.1.4 GA Security Notes

The linked OpenSSL library for Connector/Python Commercial has been updated to version 1.0.1q. Issues fixed in the new OpenSSL version are described at http://www.openssl.org/news/vulnerabilities.html.

Decoding binary protocols in python

Decoding binary protocols like the MySQL Client/Server Protocol or MySQL's new X Protocol involves taking a sequence of bytes and turning them into integers.

In python the usually workhorse for this task is struct.unpack()

It takes a sequence of bytes and a format-string and returns a tuple of decoded values.

In the case of the MySQL Client/Server protocol the integers are (mostly) little-endian, unsigned and we can use:

This is not a comprehensive review, nor an user guide. It's a step-by-step account of my initial impressions while trying the new MySQL XProtocol and the document store capabilities. In fact, I am barely scratching the surface here: more articles will come as time allows.

MySQL 5.7 has been GA for several months, as it was released in October 2015. Among the many features and improvements, I was surprised to see the MySQL team emphasizing the JSON data type. While it is an interesting feature per se, I failed to see the reason why so many articles and conference talks were focused around this single feature. Everything became clear when, with the release of MySQL 5.7.12, the MySQL team announced a new release model.

"Latest symlink"A "latest" symlink, is a symbolic link (on Linux, Unix etc) which links to the "latest" version of a file.
Suppose we have a file which takes some effort to create, which is generated periodically or in response to some stimulus (e.g. user activity). Then we want to create a "latest version" symlink.
Ideally the properties should be

• latest symlink always points at the latest version (duuh!)
• latest symlink always exists
• latest symlink never points at a partially completed, broken, missing or otherwise bad file

Sometimes people do this in a way which won't work.
How to create a symlinkDead easy, right? Just call the "symlink" function. 
 int symlink(const char *oldpath, const char *newpath);
