Load testing of IBProvider v3.50 and Firebird v3.0.4

Hello!

In this note we would like to inform you about running 6.7 million various tests for blobs. On our scale, it is a big testing. Usually we run each IBProvider update through 0.7 million tests.

Performing these 6.7 million tests in one thread would take 150 days. Parallel run in 10 threads reduced this time to 15 days.

We won’t bore you with details and will provide only key information.

Migration Guide to Firebird 3 (review)

Steve Naidamast kindly sent me his personal review of my Firebird 3 Migration Guide. I’m more than happy to share it here:

 

The Migration Guide to Firebird 3.0 is an excellently written technical manual that is filled with all the essential information anyone wanting or needing to work with Firebird 3.0 (now 3.0.x) will require.

Though called a migration guide, this well designed manual provides far more information than simply being relegated to how to move between earlier versions of the Firebird Database Engine and the most recent version of this highly capable database system. As a result, far exceeding the discussion of moving between database systems, this guide provides thorough explanations in detail on the various, unique server types that Firebird offers and how to decide which one is the best option for the requirements at hand, the necessary security configurations for each type of server and how to define users and their associated roles, enhancements to the PSQL language (the SQL variation used by Firebird), discussions on physical access to the server (ie: wire protocols), connection string enhancements, and last but not least, discussion on the Firebird Embedded Database Engine for desktop application development, which has been upgraded from the current 2.5 version.

Though written from the perspective of the needs of a Database Administrator, this manual should be an addition to any professional’s library who is serious about working with Firebird for the long term.

It is by far one of the superior manuals I have read over the years on the subject of database systems. Such manuals should surely aid in the growth of the Firebird Community so that this database system can take its rightful place among the current standards of use in today’s database application development endeavors…

Firebird fbudf Module Authenticated Remote Code Execution

Here is the description for CVE-2017-11509
An authenticated remote attacker can execute arbitrary code in Firebird SQL
Server versions 2.5.7 and 3.0.2 by executing a malformed SQL statement. The
only known solution is to disable external UDF libraries from being loaded. In
order to achieve this, the default configuration has changed to UdfAccess=None.

This will prevent the fbudf module from being loaded, but may also break other
functionality relying on modules.

Here is the Debian security page with the issue : CVE-2017-11509
And here is the original report https://www.tenable.com/security/research/tra-2017-36

The Frustrations of the long distance Database Application Developer

Though I have extensive database application development experience, I do not consider myself an expert with the Firebird Database Engine to any degree.  The following article is completely based upon observations and experiences during my attempts to learn and understand this highly capable engine.  As a result, if there are misunderstandings or mistakes I have promoted in my writing, please do not hesitate to send in comments either correcting them or offering alternatives.
