T15589: PHP 8.1 "urlencode(null)" exception blocks account registration redirect for custom OAuth provider

rARCe46025f7a914: Fix PHP 8.1 "urlencode(null)" exception blocking account registration redirect…

Summary

It seems that a tokenSecret is not always passed at this stage, and that PHP's urlencode() does not accept passing a null string since PHP 8.1 (I could not find any upstream note about this but bug reports across the web seem to confirm this).

Thus do not try to urlencode($this->tokenSecret) if it is null.

EXCEPTION: (RuntimeException) urlencode(): Passing null to parameter #1 ($string) of type string is deprecated at [<arcanist>/src/error/PhutilErrorHandler.php:261]
arcanist(), ava(), phorge(), wmf-ext-misc()
  #0 <#2> PhutilErrorHandler::handleError(integer, string, string, integer) called at [<arcanist>/src/error/PhutilErrorHandler.php:261]
  #1 <#2> urlencode(NULL) called at [<arcanist>/src/future/oauth/PhutilOAuth1Future.php:232]

Closes T15589

Test Plan

As an admin, set up custom "MediaWiki" OAuth provider from from https://gitlab.wikimedia.org/-/ide/project/repos/phabricator/extensions/edit/wmf/stable/-/src/oauth/
As an admin, apply D25373
As a user, go to /auth/login/mediawiki:whatever/
Select login button

Redirect now works as expected: The URL redirect to allow access on
http://mediawiki.localhost/index.php?title=Special%3AOAuth%2Fauthorize&oauth_token=1234567890abcdef1234567890abcdef&oauth_consumer_key=1234567890abcdef1234567890abcdef works as expected, instead of showing a raw error page about urlencode() not accepting passing null. (After allowing authorization there are more issues in Phorge code but they are out of scope for this Arcanist patch.)

I've looked at this for five minutes and unfortunately I'm afraid that I do not know.

232–236	Thanks. Does this work as well? (Also reported below to make it more visible) $key = urlencode($consumer_secret); if ($this->tokenSecret !== null) { $key .= '&' . urlencode($this->tokenSecret); }

src/future/oauth/PhutilOAuth1Future.php
232–236	No, this does not work as well. In that case I get an `Expected 'oauth_callback_confirmed' to be 'true'!` error. But your format is more readable, so I should adjust my proposal.

Yeah! it seems OK now

Would anyone be willing to give this another review? TIA

This looks like a reasonable chance to me.

I think they are fixed now

As I just ran into this again spinning up another machine and had to look this up again, I'd really appreciate if a Blessed Committer could give an "Accepted" state. Thanks in advance!

This already has been accepted. I think @Matthew 's old request for changes is what is keeping this from being landable right now.
