I was unable to reproduce these 2:
src/applications/diffusion/request/DiffusionGitRequest.php
src/applications/people/mail/PhabricatorPeopleEmailLoginMailEngine.php

The fix for src/applications/search/controller/PhabricatorSearchController.php does not generate a stack trace in the httpd error_log.
If I undo the fix, I'm not able to search for words anymore

I verified some lines but I need more help in the others.

Most of these look good, but I think some of it is outdated - can you check which is still needed?

The change in src/applications/people/mail/PhabricatorPeopleEmailLoginMailEngine.php also seems to be solved somehow.
I tried to simulate the issue with bin/mail send-test --to mturdus --subject "" and pressing CTRL-D.
I received an empty email (containing no subject and no body).

(I can't comment on my own changes, so I mention it in here)

@avivey: still red flag?

Only one fix remains. I set "unclear" in the test plan accordingly to T15536. If you still want to merge, just:

arc diff D25256
arc land

Thanks again :)
