ADO.NET provider 10.0.0.0 for Firebird is available 

Leave a comment

ADO.NET provider 10.0.0.0 for Firebird is available (with Entity Framework Core 7.0 support)

Major feature is support for Entity Framework Core 7. I know, we’re close to .NET 8 and Entity Framework Core 8 release, but my time was (and still bit is) limited so it took longer than expected. On the other hand, you can watch the whole process. Should I do the same for Entity Framework Core 8?

Overview of all the changes can be found in here.

You can get the bits from NuGet FirebirdSql.Data.FirebirdClient and FirebirdSql.EntityFrameworkCore.Firebird (and EntityFramework.Firebird).

IBX for Lazarus 2.6.3 is now available for download

Leave a comment

MWA Software is pleased to announce the release of version 2.6.3 of IBX for Lazarus.

To download go to https://www.mwasoftware.co.uk/ibx

This version focuses primarily on improved testing and documentation for the handling of international single byte character sets. It includes several fixes for handling international character sets. Users of international character sets (other than UTF8) should read the opening remarks of Chapter 9 of the Firebird Pascal API Guide for guidance on the inclusion of FPC RTL units to ensure full support, and the new section 9.8 on Firebird Exceptions.

This version has also been tested with Lazarus 3.0RC2 and includes fixes in some example programs for compatibility with the latest version of Lazarus. Specifically using the “NullDate” constant instead of assuming that NullDate has a value of zero.

Version 2.6.3 is no longer labelled as Beta.

Firebird Performance Comparer (FBPC)

Leave a comment

In my two presentations at the 20th Firebird Developers Day, I introduced firsthand the tool I created to help compare the performance between two Firebird servers (>= 2.5) in an easy and visual way.

This tool actually helped to detect a performance regression in Firebird 5 beta, which was resolved after I reported it to the core developers. The intention is to identify optimizer regressions or low performance issues in Firebird itself, or even the breaking of SQL commands due to new reserved words or syntax restrictions.

I’m making version 1.0 beta available for anyone interested. It’s a version that so far has been tested only by me, so it may and probably does have some bugs.

The FBPC runs on Windows and internally uses Firebird 5 RC1 embedded to store the tests and their results. When you run the application for the first time, it will display instructions on how to use it.

In summary, it helps you create a trace.conf to capture SQL commands executed on a Firebird server 2.5 or higher in a production environment. Then, the tool parses the file and collect the statements, allowing you to run them in a controlled environment of servers, specifying test rounds where the execution time between server1 and server2 is compared and displayed in an intuitive and visual way, enabling you to detect regressions or even commands that could not be executed due to new reserved words or syntax restrictions imposed in new versions of the DBMS.
