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 ($string) of type string is deprecated at [<arcanist>/src/error/PhutilErrorHandler.php:261] arcanist(head=master, ref.master=e4fd31ec024e), phorge(head=D25241, ref.master=b1edfea09bad, ref.D25241=b1edfea09bad) #0 <#2> PhutilErrorHandler::handleError(integer, string, string, integer) called at [<phorge>/src/applications/diffusion/controller/DiffusionBranchTableController.php:29] ``` ``` EXCEPTION: (RuntimeException) strlen(): Passing null to parameter #1 ($string) of type string is deprecated at [<arcanist>/src/error/PhutilErrorHandler.php:261] arcanist(head=master, ref.master=e4fd31ec024e), phorge(head=D25241, ref.master=b1edfea09bad, ref.D25241=b1edfea09bad) #0 <#2> PhutilErrorHandler::handleError(integer, string, string, integer) called at [<phorge>/src/applications/diffusion/conduit/DiffusionBranchQueryConduitAPIMethod.php:33] ``` Closes T15414 Test Plan: Applied these two changes and at least got to `(FilesystemException) Filesystem path "/var/repo/1/" does not exist.` as an error message, instead of being stuck at `(RuntimeException) strlen(): Passing null to parameter #1 ($string) of type string is deprecated`.
