Hi, I guess this is topic was touched a lot of times but It would be great to see your thoughts and experiences about this.
I started to develop an application that really needs to take care about concurrency issues. So I was thinking about creating a Doctrine behaviour for this that puts a couple of fields indicating a "version" and,the ID of the last user that requested the record. So, before update the record, it would check this version and, if it's different, it would throw an exception, preventing the corruption of the data. This would be my implementation of an optimistic concurrency control. Is there a better way of doing this? The other topic (althought they're closely related. For this reason I talk about them in the same post) is application / business transactions that spam multiple requests. Which would be the better way to implement this? I was thinking on creating a new form class that saves the input data on the session between requests (using a DB session storage).. and wrap everything on a transaction on the last step, checking first the "version" on every record involved (if it's now new, of course) so I'm confident that the data is not corrupted before saving the changes. What would be the best way of implement this in the form framework of symfony? I was thinking about extending the sfFormDoctrine class, override the save method and, before anything else, check if this time is the "last step" of the transaction. If not, save everything on the session and go on. If it is, check the integritiy of the data (that noone has modified anything whitin the business transaction), and if everything is fine, go on and save the record/s. I'd like to hear your thoughts about it. I want to create a plugin for each of this topics. Any help or comment would be much appreciated.
