CronTriggerTimetable is now less aggressive when trying to skip a run (#33404)
When setting catchup=False, CronTriggerTimetable no longer skips a run if
the scheduler does not query the timetable immediately after the previous run
has been triggered.
This should not affect scheduling in most cases, but can change the behaviour if
a DAG is paused-unpaused to manually skip a run. Previously, the timetable (with
catchup=False) would only start a run after a DAG is unpaused, but with this
change, the scheduler would try to look at little bit back to schedule the
previous run that covers a part of the period when the DAG was paused. This
means you will need to keep a DAG paused longer (namely, for the entire cron
period to pass) to really skip a run.
Note that this is also the behaviour exhibited by various other cron-based
scheduling tools, such as anacron.
conf.set() becomes case insensitive to match conf.get() behavior (#33452)
Also, conf.get() will now break if used with non-string parameters.
conf.set(section, key, value) used to be case sensitive, i.e. conf.set("SECTION", "KEY", value)
and conf.set("section", "key", value) were stored as two distinct configurations.
This was inconsistent with the behavior of conf.get(section, key), which was always converting the section and key to lower case.
As a result, configuration options set with upper case characters in the section or key were unreachable.
That's why we are now converting section and key to lower case in conf.set too.
We also changed a bit the behavior of conf.get(). It used to allow objects that are not strings in the section or key.
Doing this will now result in an exception. For instance, conf.get("section", 123) needs to be replaced with conf.get("section", "123").
