KMAC denotes a secret MAC key known only to our application, and the operator + denotes string concatenation. Furthermore, d is a suitable separator character for example, ; that does not appear in values of our cookie C; it is used to ensure uniqueness of the concatenation. To validate an incoming HTTP request, our application performs the following steps: 1. It extracts the request URL L' (without the query part in the case of a GET request) and the cookie C' from the request. 2. It computes the expected value of the action token for these values of the URL and cookie:

To better understand how event handling works, you can create a widget that emits a signal carrying a string that tells you which event has just been received. The widget class is called EventWidget, and the signal is named gotEvent(const QString &). By hooking this signal to a QTextEdit, you get an event log that you can use to explore the events. Start by having a quick look at Listing 6-9. The EventWidget has a range of event handlers, and the responsibility of each is described in the following list. These event handling methods are some of the most common ones, but there are more. In each line in the list I kept the event object type with the event name so that you can see which events are related. For instance, all focus events take a QFocusEvent pointer as argument.

There is one potential problem to keep in mind with activate/deactivate. The shell keeps the path of each command in memory so it doesn t have to look it up again when the command is reexecuted. This bypasses activate s changes to the environment, so activate and deactivate try to clear this cache, but sometimes they fail. The result is that you type the command name and get the wrong one. To make 100 percent sure you re getting the right command, run which python (or which easy_install, and so on) to see the full path of the command that would have executed. If it s the wrong one, execute it once by typing the full path, and it will update the memory cache to use that version of the command. If in doubt, it is probably worth using the executables directly without the activate/deactivate magic.

3. It extracts the actual value Trequest of the action token from the appropriate request parameter. 4. If Trequest equals Texpected it continues processing the request. Otherwise, it assumes that an XSRF attack may be underway, and does not process the request. It is possible that occasionally a request initiated by a legitimate user will fail action token validation according to this algorithm. This can happen, for example, if a user leaves a page containing a form open in their browser, and concurrently initiates a new session with the application in a different browser window. Then, the action token in the form in the first window will become stale because its value is based on a previous value of the session cookie and will not match the expected value based on the current value. Thus, the application should recover gracefully in the last step, and instead of displaying an error message after a token mismatch, reply with an HTTP redirect response that sends the user to a suitable page (e.g., the application s Home or Main Menu page).

It can sometimes be difficult to remember exactly what rules apply to defs, particularly when you get involved with more complex examples such as the inheritance chains you ll see later in the chapter. Luckily, there is an easy way to find out what is going on behind the scenes.
