Hello Glance team! About a month ago the oslo team released 3.17.0 of oslo.log which contains [1] which switches the default for use_stderr from True to False. It hasn't made it into upper-constraints.txt because glance is failing[2]. There are 2 easy fixes: 1) switch the glance test to look at stdout rather then stderr ; or 2) update the glance config files to explictly set "use_stderr = true" I feel like Option 2 is correct as clearly preserves the existing behaviour the operators/deployers can opt out if they want. Let me know which option I should write tomorrow. As Ceilometer (at least) doesn't use constraints they've already found this and took Option 1 in [3] Yours Tony.
