I've polished the patch attached to #5586 by Timo Aaltonen.

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


Won't this break existing certmonger requests depending on
the old

It will, I don't see any upgrade code.

# getcert list | grep '/usr/lib64/ipa/certmonger'
       pre-save command: /usr/lib64/ipa/certmonger/stop_pkicad
       post-save command: /usr/lib64/ipa/certmonger/renew_ca_cert
       pre-save command: /usr/lib64/ipa/certmonger/stop_pkicad
       post-save command: /usr/lib64/ipa/certmonger/renew_ca_cert

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
(see the other thread). IMO there should be 2 patches: the first
add the ability to change DS and HTTP certmonger config during
(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()

Honza, do I understand it correctly that the code is OK but I did not
split it to the patches correctly?


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

2) Does it go and try to edit the requests on every upgrade? Or is
there some
check that requests were updated?


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

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:


A cert could silently fail to be tracked in
start_tracking_certificates() if no serverid can be found.

In that case it also wouldn't be stopped. The behavior is the same as in existing stop_tracking_certificates(). Should we rather raise and stop the upgrade? I guess not but warning would be probably useful. What solution would you prefer, Rob?
