Just wanted to test how this bug manifests itself (see above) and if it's different from @Krenair's T125834 (it is; T125802#1998113 looks different).

That bug is about input via email, not via the web interface.

This should be resolved upstream by https://secure.phabricator.com/D20562.

I'm going to tweak the title here to align it slightly better to the desired/implemented behavior: it's intentional that we don't trim leading and trailing whitespace out of the input entirely because <space><space>xyz is a valid comment starting with a piece of codeblock-formatted text.

epriestley renamed this task from Phabricator comment input should trim whitespace to Phabricator should treat comment inputs containing only whitespace characters as empty when deciding whether the user made a comment or not.May 30 2019, 7:39 PM
