* josevalim/jv-persistent-set-env: Allow persistent option on set_env/4 and unset_env/3 OTP-11708

2014-02-11Allow persistent option on set_env/4 and unset_env/3José Valim
An environment key set with the persistent option will not be overridden by the ones configured in the application resource file on load. This means persistent values will stick after the application is loaded and also on application reload.
2013-07-11Add application:ensure_all_started/1-2Fred Hebert
This adds two new functions to the application module that will recursively look for missing dependencies to start the entire dependency chain of a given application, and then the application itself, if possible. Its entire behavior is based on the currently existing 'start/1-2' functions, which will report dependencies that have not yet been started and other problems encountered. 'ensure_all_started/1-2' will use this information the way any programmer would manually do it to automate the process. This kind of functionality, while not OTP-ish (releases do this start sequence for the user), is still useful for testing purposes, quick demonstrations, and programmers who do not wish or know how to use OTP releases. The function returns '{ok, StartedApps}' for all started or already started applications (already started are omitted from the list), and will return '{error, {AppName, Reason}}' on a failure to allow users to rapidly know why the function failed. Note that no specific check is made for direct or indirect circular dependencies between applications, and these will make the function go in an infinite loop.
2013-03-05kernel: Add application:ensure_started/1,2Björn-Egil Dahlberg
Similar to application:start/1,2 except it returns 'ok' on already started applications instead of {'error', {'already_started', ...}}.

2013-01-14Add application:get_key/3serge
The new function provides a default value for a configuration parameter.
2012-09-13Don't allow {Mod,Vsn} in modules list in .app fileSiri Hansen
It was possible to insert {Mod::atom(),Vsn::term()} instead of Mod::atom() in the modules list in a .app file. This was not visible in the documentation of .app files, but it was visible in the documentation of application:load/[1,2] (where the .app file term can be used directly as first argument). The Vsn part was never used, so this possibility has now been removed.
