Fix PHP 8.1 "strlen(null)" exception rendering dashboard panel with latest tasks when custom text field configured
ClosedPublic

Details

Summary

strlen() was used in Phabricator to check if a generic value is a non-empty string.
This behavior is deprecated since PHP 8.1. Phorge adopts phutil_nonempty_string() as a replacement.

Note: this may highlight other absurd input values that might be worth correcting
instead of just ignoring. If phutil_nonempty_string() throws an exception in your
instance, report it to Phorge to evaluate and fix that specific corner case.

EXCEPTION: (RuntimeException) strlen(): Passing null to parameter #1 ($string) of type string is deprecated at [<arcanist>/src/error/PhutilErrorHandler.php:261]
  #0 <#2> PhutilErrorHandler::handleError(integer, string, string, integer) called at [<phorge>/src/infrastructure/customfield/standard/PhabricatorStandardCustomFieldText.php:33]

Closes T15684

Test Plan

After configuring a custom text field and a dashboard panel to query and listed the latest created tasks, access the panel.

Hmm, I guess the patch should also change line 14 in the same way? I managed to reach that line with the same problem but do not remember the exact steps I performed...

Yes, we can do that also in line 14

To reproduce the crash there, I visited the page

/config/edit/maniphest.custom-field-definitions/

And I've added this custom field with search enabled:

{
  "megalol:favorite-dinosaur": {
    "name": "Favorite Dinosaur",
    "type": "text",
    "search": true
  }
}

I can sticky-accept the change. Feel free to update line 14 and land (no need to re-approve again here).
