From 7aee6304f653475a4130dc3e5be602e91481f108 Mon Sep 17 00:00:00 2001 From: Brant Knudson Date: Thu, 31 Jul 2014 17:47:00 -0500 Subject: [PATCH] Fix revocation event handling with MySQL When MySQL is used to store revocation events, events are returned from the database with the timestamps truncated to the second. This causes a revocation event for a token (which has the issued_at timestamp to the microsecond) to not match the revocation event and therefore the token is not considered to be revoked. The fix is to have the revocation events and token timestamps both always be truncated to the second. This will cause all tokens for a user that are issued within a second to be revoked when any of those tokens are revoked, which shouldn't be a problem.
