Hi!
I made progress turning my optional old-style group cohomology spkg into
a new style package (called "modres", to be added to Sage at some point)
depending on another new-style package (called "meataxe", already part of
Sage), both being wrapped by an OptionalExtension in the Sage library.
Alert me if that's not the way to do it...
My first question is about logging. The old spkg has a custom logger
that tells by what object it was called, unless it is called repeatedly by
the same object. Thus, if it is called by object A with messages m1 and m2,
then called by B with messages m3, m4, and again by A with message m5, it
prints
A: m1
m2
B: m3
m4
A: m5
I find that formatting kind of nice and I would like to keep it. But a
potential referee might argue that a custom logger should better be
replaced by using Python's logging module. So, my question: Do you see
an easy way to obtain the above logging behaviour with Python's logging
module ("easy" is a way that does not involve writing a complicated
handler to be passed to a logger by addHandler()).
My second question is about optional tests. It has been discussed before
whether to have a way to mark *all* tests of a module optional. Has it
meanwhile be implemented in the test framework? After all, we now have
OptionalExtension in module_list.py, and obviously the tests of an
optional extension should be optional, isn't it?
Best regards,
Simon
