Hi operators/devs,
I have a patch [1] for oslo.context (the library that is used by most
projects to create context objects to pass around) that introduces the
following change for the context:
user_identity is now constructed from user and project names instead
of user-id and project-id, in case names are available.
The change introduces a slight incompatibility in context aware logs
[2] (controlled by oslo.log library). Specifically, before the change,
those log messages looked like:
"date time DEBUG python-path [req-283bde30-6f3d-4f20-83c9-17c3185e2b88
049f3e6a87a649b288bed5543a052dd3 231bb797af67435fa6603282aa461c9a - -
- -] log-message"
where 049f3e6a87a649b288bed5543a052dd3 is user-id and
231bb797af67435fa6603282aa461c9a is projects.
While after the change, the same log message would look like:
"date time DEBUG python-path [req-283bde30-6f3d-4f20-83c9-17c3185e2b88
username projectname - - -] log-message"
The incompatibility would show up only if someone relies on those
fields to represent user and project IDs.
The change is to avoid the need for devstack to override oslo.log for
particular services [3] to get those user and project names, so that
we consume the default format string from oslo.log everywhere and make
our logs consistent and probably more user friendly (it's probably
easier to read user name than user id in your logs). Also we would
avoid bugs like [4] where we miss valuable log info because of old,
inadequate configuration.
The question is: does anyone know of any piece of software or an
operator who relies on particular format of those fields? Does anyone
think that such a change should not go in?
