Ok. Till now I have created a pair of actions; one which I call at the start of my rule to impersonate "node changing user", and one at last to change back. Using this I can call scheduled rules with the user who triggered them. It is all I need to the moment, so I will stop looking further into batching actions (limited time).

drupal_static() is not equivalent to PHP static. The example you've given is using PHP static and yes, it will not be available in another function.

I know we are going OT, but I also want to understand this;
what about:
function mymodule_complex_calculation() { static $cache; if (isset($cache)) { return $cache; } // Otherwise we need to perform our calculations // ...some complex calculation that returns $cache = complex_calculation(); return $cache; }

You are saying that if I instantiate a variable in
"mymodule_impersonate()"
it will not be available in "mymodule_unimpersonate()"?

You "think" wrongly. A static variable has local scope to the function declaring the static variable.

Static variables are only saved for a single function. Global
variables
are available to all functions during a single page request. Session variables are available to all page requests during a session.

Darren, thanks for the link. What is the difference between using global or static to save the data?

My code was from a module where impersonation recursively could happen, this is why I use a stack to save user state. I am also saving it to session and not using a static variable because I may uses batch functions.
But I see some problems right now: - To be safe impersonation should be saved into static variables
(and
"using session_save_session(FALSE);" ), so if anything goes wrong, $user is not afected. - If I want to be able to execute every Rules action in a batch, I need to change user "per action"
Any idea of how to "inject" code before and after a rule action?
