I've recently been working on building my own wiki engine for my blog site. While the majority of the engine is complete, a remaining concern I have is how to handle competing edits (ie when two or more people are editing the same wiki page simultaneously). I'm wondering if anyone else on the list has given this some thought? How would / do you handle competing edits to the same entry in a wiki application?
Just like Wikipedia -- that is, send a timestamp in a hidden form field with the edit box. When the form is submitted, throw an error if there is an edit more recent than that timestamp (an "edit conflict").
If your pages have sections, like Wikipedia's, then you can configure your software to only throw an error if there is an edit conflict with that section.
Also, it's probably a good idea to make use of transactions in an ACID-compliant storage engine like MySQL's InnoDB, if possible.
