Thanks for the patch. I've fixed the path in specfile and removed
unused import
but otherwise it works, ACK.

Won't this break existing certmonger requests depending on the old
path?
It will, I don't see any upgrade code.

You're right it will break the upgrade. I haven't noticed that
Server-Cert for DS and HTTPD are not handled by
certificate_renewal_update (ipaserver.install.server.upgrade) where all
the other trackings are stopped and then configured again with the
paths.CERTMONGER_COMMAND_TEMPLATE already updated.
Thanks for the catch.
I've updated Timo's patch little more and added
start_tracking_certificates() for dsinstance and httpinstance. Now the
upgrade works as expected.
The way the patches are split is kind of weird and apparently confusing
(see the other thread). IMO there should be 2 patches: the first should
add the ability to change DS and HTTP certmonger config during upgrade
(i.e. the start_tracking_certificates() methods and
certificate_renewal_update() changes), the second should move the
helpers (i.e. the actual move and certificate_renewal_update() version
bump).
Honza, do I understand it correctly that the code is OK but I did not
split it to the patches correctly?
Yes.
Before acking or pushing, can you please explain for me how the upgrade of
certmonger tracking requests work? I want to make sure this is right, so please
bear with me:
1) How does it edit existing tracking requests with the new helper paths?
2) Does it go and try to edit the requests on every upgrade? Or is there some
check that requests were updated?
Thanks,
Martin
Whole upgrade of renewal requests is done in
ipaserver/install/server/upgrade.py in certificate_renewal_upgrade().
First there is version of requests and if it's the same as in state file
upgrade is skipped.
Then every request is searched over certmonger's DBus interface and if at least
one is not found it means that there was change in request configuration. All
tracking requests are then stopped and started again with new configuration.
So to answer you questions:
1) By stopping the old request with the old parameters (including path) and
starting new with new parameters.
2) Only if version was bumped which happens only if some of the requests
changes.
Ah, so IIUC, if you bump the version, requests should be properly updated. The
change looks fine then.
After discussion with Honza, we decided to drop the part comparing only
base names of pre- and post-save commands and use it as whole. I've also
split the patches so it's obvious what is going on.
Patches should be applied in this order:
freeipa-dkupka-0091.0
freeipa-dkupka-0087.1
freeipa-dkupka-0088.1
freeipa-tjaalton-0011.2

The scripts in this directory are simple python scripts, nothing arch-specific
in them. Having them under libexec would simplify the code a bit too, since
there would be no need to worry about lib vs lib64 (which also cause trouble
on Debian).
