[Security] Rename UserInterface::getUsername() to getUserIdentifier() #40403

This continues the great work by @chalasr in #40267 and rounds up the UserInterface cleanup.

The getUsername() has been a point of confusion for many years. In today's applications, many domains no longer have a username, but instead rely on a user's email address or the like. Even more, this username has to be unique for all Security functionality to work correctly - so it's more confusing in complex applications relying on e.g. "username+company" to be unique.

This PR proposes to rename the method to getUserIdentifier(), to more clearly indicate the goal of the method (note: I'm open for any other suggestion).

For BC, the getUsername() method is deprecated in 5.3 and getUserIdentifier() will be added to the UserInterface in 6.0. PHPdocs are used to improve type-hinting for 5.3 & 5.4. Both authentication managers (the legacy and experimental one) check the authenticated user object and trigger a deprecation if getUserIdentifier() is not implemented.

judge whether we need to have better deprecations for calling getUsername() in the application code.

Consistent with these changes, I've also done the same BC change for TokenInterface::getUsername().

do the same for remember me's PersistentTokenInterface::getUsername()
also rename UserProviderInterface::loadUserByUsername() & UsernameNotFoundException
also rename UserLoaderInterface::loadUserByUsername()

I'm very much looking forward for feedback and help for this important, but BC-heavy, rename. 😃

Looks good! Thank you for this, Wouter.

Given that DebugClassLoader will automatically trigger a deprecation notice thanks to the added @method phpdoc, I'm fine with the proposed BC layer and the additional notices it introduces.

Regarding tests, we should keep some legacy ones using the deprecated method to make sure everything keeps working.

Thanks Robin!

Oh, that's nice. The powers of the DebugClassLoader keeps surprising me :)

Regarding tests, we should keep some legacy ones using the deprecated method to make sure everything keeps working.

Yes, sure thing. I've basically been find&replacing getUsername() occurrences in the tests (to see if this actually works). This PR needs lots more love before it's ready.

I guess we will need to rename UserProviderInterface::loadUserByUsername() here

+     */
+    public function getMessageKey()
+    {
+        return 'Username could not be found.';


How would we consider BC on this public error message? I think we cannot change it?

No, it's not BC break. We can change it, but (not a blocker) that invalidates all translations (so, we need updates on translations as well).

that also break things if a project was customizing the translation messages in their own messages, as they won't be overriding the translation being used anymore.

After @stof's comment, I think it's best to keep the message unchanged.

Also, User identifier could not be found is a much to technical error message to have as a default user-friendly message imho. I think most applications that care already updated this to say e.g. "E-mailaddress could not be found", so "Username" seems a good default for the others.

wouterj · 2021-03-11T22:58:53Z

For reference, I consider this PR to be "feature complete". However, we do need to have more tests to make sure all authentication providers/listeners can work with both the old and new names. I'll add these over the next few days.

I think this PR is ready. However, 2 comments are left unresolved (open discussion), and the travis high builds are failing (I guess I need to submit another PR for 5.2 to change all tests to fix them?).

appveyor builds have a timeout, they were green before.

fabpot · 2021-03-16T18:13:40Z

The merge of the User rename makes a lot of conflicts here, sorry about that :(

@wouterj Do you have time to rebase this PR?

wouterj · 2021-03-28T13:17:24Z

Rebased. I believe the deps=high builds will be fixed when #40609 is merged (other failures are unrelated). I'll rebase this PR again when that PR is merged up to 5.x.

If we ignore psalm (which we should in this PR), we're finally green. Thanks for your help @chalasr!

@wouterj @fabpot Removing a method from an interface isn't a BC-break ?

If I use $user->getUsername() in 5.2, I now can't be sure it still works in 5.3.
Also keeping the method would solve the psalm issues.
