Linux/s390x support for Firebird 2.1.2

Dan Horák wrote on firebird devel list:
I am a Fedora and Red Hat Enterprise Linux developer and we are now
porting whole Fedora package collection to the s390x (IBM System z a.k.a
mainframe) architecture. The official sources for Firebird (in version
2.1.2) didn’t support this architecture, so I have prepared a patch that
adds this support. Please let me know what else should I do to get the
support accepted into the official source tree.

the patch was uploaded to
http://tracker.firebirdsql.org/browse/CORE-2559

successfully built Fedora-11 package is at

Firebird Protocol

Hi,

I’ve been working on an improved plug-in for wireshark (previously known  as ethereal) and have produced a “Wire Protocol Specification” as a  byproduct.

From my preliminary reading of news groups, etc., several people have  asked for this kind of information. It’s not complete, it’s not correct  but it’s better than anything else I have been able to find.

It should go in your Documentation and Papers section.

Regards,
Mark Chambers

Trees in the database: Advanced data structures

Lorenzo Alberton wrote in his blog about his paper presented at PHP conference

Storing tree structures in a bi-dimensional table has always been problematic. The simplest tree models are usually quite inefficient, while more complex ones aren’t necessarily better. In this talk I briefly go through the most used models (adjacency list, materialized path, nested sets) and introduce some more advanced ones belonging to the nested intervals family

ED: some of the principles can be applied to Firebird with CTE

What roles is user able to use?

About a month ago there was a question in Firebird (CZ) group how to find whether the user is able to use particular role or to get all roles for user.

As you probably know, a lot of stuff (almost everything) is in system catalog (system tables). The only problem is to figure out what’s the right set of parameters to use. To get all roles with users able to use it, you can use …
