This does not seem possible, unless we add more info about steps to
the registry: the name of the xml file that the handler of that step
will read.

I added that.  I have no commit rights, so for the total changes
(including the previous one for the Profiles tab), see here:


Just select your favorite extension profile, perhaps select some steps
and then click the Import selected/all button.

The tests still pass, but I did not add extra tests.  The current
manage_* methods from the setup tool are also not tested, so I do not
feel very guilty. ;-)

One thing that we may want to do differently: with this code it is
possible to create a new Zope and Plone site, go to portal_setup, go
to the Import tab *without* going to the Profiles tab first, select
the eXtremeManagement extension profile (if you have that in your
Products dir) and run all steps.  Then all steps get run, except the
importVarious step, as that has not been registered yet.  Wait, that
does not actually happen.  The importVarious step gets run after all.
Maybe it now gets registered on the fly in some part of the code.  Oh

One other thing that strikes me as odd: I added a few lines in my
setuphandler like:

    logger.info("Migrated schema of %s", contentType)

In the event log this correctly gives lines like this:

  INFO GenericSetup.eXtremeManagement Migrated schema of eXtremeManagement.Task

But the message log on the import tab gives me lines like this:

  eXtremeManagement: Migrated schema of %s

So the argument is lost somewhere.

I now changed that to:

    if not context._profile_path.startswith(os.path.split(__file__)[0]):
        logger.info('Nothing to import: not in eXtremeManagement path')

I see that some other products (Plone, CMFEditions) use a different

    # Only run step if a flag file is present
    if context.readDataFile('cmfeditions_various.txt') is None:

So they add a simple text file to their profile directory and if that
does not exist in the current import context, then the importVarious
function quits.  Works too.

Any thoughts on which of the two strategies is better?

Hm, I just selected my importVarious step and ran that step with its
dependencies, but I did that with the base (Plone) profile.  This step
has three dependencies.  These dependencies are imported (but with the
xml files from Plone as their data) and then the importVarious step
itself exits early because of the check I added:

INFO GenericSetup.propertiestool Properties tool imported.
INFO GenericSetup.catalog Catalog imported.
INFO GenericSetup.workflow Workflow tool imported.
INFO GenericSetup.eXtremeManagement Nothing to import: not in eXtremeManagement path

So the dependencies are run, but then the code in the depending step
realizes it does not actually need to run itself, so running the
dependencies was not really needed.  I understand what is happening,
but it sounds a bit wrong to me.
