Abstract out session store from SessionManager#4567
Conversation
Added abstractions and a default implementation for a session store to be used with the Blazor state SessionManager. The default implementation continues to use in-memory persistence in a ConcurrentDictionary.

I think @StefanOssendorf would be much happier if this had async methods instead of sync methods 😁
Seriously though, if we're going to improve the code like this, I do think we should expect that people will use async stores for the data.

Yes please :)
You can always do sync with a Task/ValueTask method but not async with a void method :)

I don't like this method name. Perhaps it should be more explicit that this is expiring sessions?
| /// </summary> | ||
| /// <param name="key"></param> | ||
| /// <param name="session"></param> | ||
| void CreateSession(string key, Session session); |

Could the create/update be combined to a TryUpdate or something similar?

AddOrUpdate like the ConcurrentDictionary methods?

No hard-coded use of English is allowed in the framework. This needs to be from a resource string or be ArgumentException(nameof(HasValue))

My suggestion to get rid of this exception would be: Don't allow the creation of an invalid object state.
- Make
Expirationnon nullable. - Either add a constructor expecting the value and/or make the property
required
With those changes the whole Validate() method becomes obsolete.

This is basically internal to the default implementation right?
As in, if someone were to use a different session store they'd probably use their own approach for expiring old data.

No. Currently this class is part of the public API.
ISessionStore.DeleteSession(SessionsFilter)

I really appreciate this refactoring - absolutely on the right track. While we're doing this, might as well also embrace async.
Perhaps also consider using file scoped namespaces so Simon doesn't need to come back later and clean that up?

Why do you suppress with !? You should check for it and handle the default case.

@rockfordlhotka This is a change for v10. It's a breaking one ;) |

Although this is a good change, I think this particular PR is so out of date now that it is beyond hope. If I'm wrong, please reopen and update, otherwise it'll stay closed. |
Added ISessionStore abstraction for Blazor SessionManager to support load-balanced environments with pluggable session storage. Addresses review feedback from PR MarimerLLC#4567: - Async interface using ValueTask - Combined Create/Update into AddOrUpdateSessionAsync - Renamed DeleteSessions to PurgeExpiredSessionsAsync - Removed SessionsFilter class - File-scoped namespaces - Proper null handling
