Imebra: test units for transactions & global locks |
|
|
|
All the test units for the transactions and the global locks passed and paved the way to the next version of Imebra, that should be released in the middle of May.
A global lock is a mutex shared by several objects; it is used by the dataSet and all its components (groups and tag objects) and by the image and its buffer.
The transactions objects force the update of several elements in "one go".
This means that when several writing handlers are deallocated, the modifications are kept on hold until the transaction object is deallocated; if one of the modifications doesn't complete successfully then all the modifications are rolled back and the dataset remains in a consistent state.
