This design implies we will never be able to + * provide key level locking at the storage level: we are doomed to implement + * the session locking at global session level.

While this is a + * good thing, we have to be careful and fix every bit of code using it. + * + * - We have a chicken and egg problem: the database storage does not rely on + * uid field anymore, which means it won't try to update or insert it when + * writting session: in order for this code to work, you must reinstall core + * properly or run the update.php in a session less environment in order to + * ensure that no write access on the table will be made until the update + * ran. + * + * - If we switch to 2.1 version of Symfony, we will have to port some specific + * stuff, such as the DatabaseSessionStorage. Aside from that nothing should + * change for us. The only exception seems to be for Flash messages, but we + * will port Drupal messages to Symfony Flash messages only once the core + * session is working and accepted. + * + * - The real lazy session loading will come only if we have a lazy user + * loading that itself relies on session. + * + * First way to go in order to restore most lost features: + * + * - Implement a session token provider (chained or not) whose first + * implementation will be the Drupal original dual cookie session token + * handling. + * This is done, see Drupal\Core\Session\SessionTokenProviderInterface + * First working implementation that emulates PHP native behavior is + * Drupal\Core\Session\NativeTokenProviderInterface + * + * - Later if we need to, we would be able to inject the token provider (I'm + * thinking about unit tests), for that we need a decent component container. + * + * - Another feature we could implement is having a provider chain (multiple + * different ways to provide a session token, GET, POST, cookie, could be any + * other mechanism). The chain would be a chain of command pattern where the + * first provider to answer positive about having a session token would be + * fixed by the Session object as being the only one that will interact with + * the runtime. + * + * - The actual session token provider needs to be accessible publicly, which + * is not the most efficient way we could be managing it. In an ideal + * world, this component would be injected at Session object construct + * time and hidden into it. + * + * Then, for performance matters we need to: + * + * - Implement the user token being actively stored into the session data + * instead reloading it. This implies that, for security matters, we need + * to check user token validity on session start: we will remove at least two + * SQL queries (one of user fetch, the other for roles fetch) but we will add + * at least one SQL query (check user validity).
