eXpress Persistent Objects (XPO)

XPO (an object-relational mapping library – ORM) supports more than a dozen database engines (including SQL Server, Oracle and various Open Source products) and recently got updated to support Firebird 3 too.

Firebird

In addition to SQL Server, MySql, PostgreSQL and SQLite, XPO for .NET Core / .NET Standard 2.0 supports ADO.NET provider 5.11+ for Firebird starting with v17.2.5. As we noted in our introductory post, the lack of support for other providers is not an XPO limitation – as soon as RDBMS vendors begin supporting .NET Standard 2.0, we will test XPO with these RDBMS providers and add them to our supported list.

Support for Firebird 3.0 server and the client ADO.NET data provider (FirebirdSql.Data.FirebirdClient 5.8.0) will be available in v18.1. We will also support the Substring criteria function that was missing before.

Firebird Synchronization to AWS Cloud.

Happy to announce a new release and general availability of Bipost Sync, a tool designed for synchronizing Firebird SQL (Windows) to AWS cloud.

Built for developers in mind.

Bipost Sync is ideal to extend your on-premises Firebird DB’s to the cloud, and build web applications, web services and API’s on top of AWS cloud platform.

It is also a great way to consolidate information from separate databases and locations, e.g. manufacturing companies may want to read sales and inventory information from 2nd or 3rd tier small retailers.

Tech Stuff:
(*) Synchronize specific data sets from Firebird SQL on Windows to AWS Aurora-MySQL.
(*) Two-way synchronization available, from AWS Aurora-MySQL back to your Firebird SQL.
(*) No need to create/alter schemas, this is done by our sync tool.
(*) Prepare your data before you load with stored procedures you define.
(*) Transform your data after load is done, also with stored procedures you define.

MWA Software is pleased to announce that release 2.2.0 of IBX for Lazarus is now available for download from mwasoftware.co.uk/ibx. This is an important update to IBX and all users are recommended to upgrade to the new release. Please read the changelog before upgrade.

The main intent behind the release is to add support for the remaining Firebird 3 features (and some from earlier Firebird releases) that were not supported in release 2.1. This includes:

  1. Support for SQL Statements INSERT/UPDATE/DELETE…RETURNING. The first two cases are now able to update the current row for all TIBCustomDataset descendents including TIBTable, using data returned following a row insert or update.
  2. INSERT…RETURNING is used to provide support for Firebird “Identity” columns. For example, when used to provide auto-increment primary keys.
  3. Firebird “Packages” are now supported by TIBStoredProc and by the SQL Component Editors.
  4. Additional Firebird 3 properties are now supported by TIBDatabaseInfo and by the Services API components (e.g. TIBConfigService).
  5. Alternative Security Databases are now supported by the Services API Components.
  6. TIBExtract now supports DDL Grants and triggers on database objects.
  7. A new IBServices component to support online validation of a database (TIBOnlineValidationService).
  8. A major new example application (DBAdmin) is now included. This illustrates the use of IBX for Day-to-Day Database Administration tasks including User Management, Backup/Restore and Database Validation and Repair. It is also intended to provided a useable application that users may use directly or incorporate into their own toolsets. It also demonstrates User Management using Firebird 3 virtual tables and SQL statements. Note: this application also requires the standard Lazarus package MemDSLaz.

This release also incorporates recent bug fixes and includes a 33 page guide to the use of IBX for Firebird DBA activities.

IBX for Lazarus may be downloaded from: www.mwasoftware.co.uk/ibx

or by subversion from:

The Firebird Developers Day is an annual Firebird conference that happens in Brazil. So far, it was mainly a Portuguese speakers conference, but this year, when FDD completes its 15th birthday, we are checking the possibility to receive international attendees too. The conference date is August, 18 2018.

The first thing we need to do is to figure out if people outside Brazil has interest to participate in FDD. So, if you live outside Brazil, and would like to come to the 15th Firebird Developers Day, answer this 3 questions survey and let us know!

Fix for Meltdown and Spectre will affect your server performance!

Microsoft, Apple and several Linux distros started to distribute patches to try to fix the recent security flaws found in Intel, AMD and ARM CPUs, in almost every CPU released in the last 20 years. The security flaws are known as Meltdown (affects Intel) and Spectre (affects Intel, AMD and some ARM processors).

The flaw allow softwares to access protected memory areas that should be accessed only by the Operating System kernel, and get sensitive data, like passwords, etc.

There are two problems with the fixes:

  1. They do not fix 100% of the problem, since it is related on how the CPUs were designed. So far, there is no 100% solution for the problem, and probably it will never exists.
  2. They impact badly in performance.

In a recent post to firebird-devel list, an user reported that the performance of the Firebird server dropped ~30% after he upgraded its Linux kernel to a version that “fix” those security flaws.

General reports over the internet shows that the most affected areas of the system are CPU, RAM and Disk, so any software that makes intensive use of some of those areas will probably have its performance significantly degraded.

Just to be clear: this performance loss doesn’t affect only Firebird, but any software!
