How to reproduce

  1. Create a repo with a callsign, for example rABC
  2. Now change the callsign, the URL is diffusion/ABC/manage/basics/ in that case

Expected result

  • New Callsign got saved
  • You are now again at the basics page

Actual result

  • New Callsign got saved
  • You get a 404, because (for example you change rABC to rXYZ), phabricator still redirects you to diffusion/ABC/manage/basics/ instead of diffusion/XYZ/manage/basics/, so you get a 404, because the old callsign is not present.

Event Timeline

I dinked around on this but for the life of me, can't find where it's getting the URI from. I did learn how paging works in EditEngine though.

Yeah, this is a little obscure since I was trying not to build more than we needed. The URI comes from DiffusionRepositoryManagementPanel->newEditEnginePage(), which does this:

$key = $this->getManagementPanelKey();
$label = $this->getManagementPanelLabel();
$panel_uri = $this->getPanelURI();

return id(new PhabricatorEditPage())

getPanelURI() has an implementation above:

final public function getPanelURI() {
  $repository = $this->getRepository();
  $key = $this->getManagementPanelKey();
  return $repository->getPathURI("manage/{$key}/");

The problem is that this URI is being generated before you do your edit, and the URI contains the (old) callsign.

A hacky approach would probably be to override getEffectiveObjectEditDoneURI($object) in DiffusionRepositoryEditEngine, and do something like this:

$page = $this->getSelectedPage();
if ($page) {
  $key = $page->getKey();
  return $object->getURI("manage/{$key}/");
return parent::getEffectiveObjectEditDoneURI($object);

I think that will fix it? I'm really not happy with how these methods are working right now and plan to clean them up a bit -- I probably made the behavior too simple in Diffusion, and then kind of weird in Settings.

epriestley edited projects, added Diffusion (v3); removed Diffusion.
