Start using gmane.org for news / archive / blog interface for firebird related mailing list

I suggest to drop Atkins [for news readers] and start using gmane.org. I use it for several years in FireBase, and it had always been very stable.

We have also archive on mail-archive :

http://www.mail-archive.com/firebird-docs <at> lists.sourceforge.net

Delphi, Firebird, IBObjects and Transaction Management

Leave a comment

I recently had reason to revisit transaction management in our application. The application makes extensive use of data aware grids (TDBGrid) and, as I am sure everyone is aware, it is impossible to explicitly manage transactions when you are displaying data in a grid.

Fortunately, IBObjects provides the means to automatically clean up transactions left hanging by TDBGrid. Unfortunately, this isn’t as well documented or as straightforward as I would like. So, after much research using the programmer’s secret weapon (Google) and a few questions posted to the IBObjects support group (thanks Jason) I think I finally understand how it works.

Philippe Makowski did some TPC tests and posted the results at fb-devel:

Hi,

I’m a bit puzzled by the results I get I made test on Fedora 16 with Kernel 3.1.1-1.fc16.x86_64 on LVM2 Logical Volume of 10G

Firebird 2.5.1 package for Debian Stable named Squeeze

Leave a comment

Damyan Ivanov announced :

I have prepared packages from the current version in wheezy
(2.5.1.26351), built for squeeze.

ftp://ftp.modsoftsys.net/public/firebird2.5-backports/

If these improve the situation, then we at least know the bug is fixed
in that version and can start looking for the exact fix, which would
take about 10 iterations (and probably several weeks).

 

[ED if you want to rebuild them for 32bits you can use these instructions ]
