Hi fellow developers,
I have written documentation about the 'Co-ordinated DB Access (Thread-safe DB Access)'. This is the new way in which DB Access operates in OpenPetra since trunk Rev. 2837 (March 16th, 2015).
The changed approach fixes many bugs in our tracker. While this is a non-breaking change, it is important for you to understand the changes that were made, why they were made, what different behaviour you must now expect from DB Access in OpenPetra, and what the all-new options for running DB access in different threads are!
Please read the following OpenPetra wiki article if you are doing any database-related development in OpenPetra:
Co-ordinated DB Access (Thread-safe DB Access).
I have also added another article on stopping/cancelling of DB operations to the OpenPetra wiki.
