I would like to discuss the merge of `del_master_managed()` function
from `ipa-replica-manage` command into the server_del API call that is a
part of the managed replication topology design update (see also the
corresponding upstream ticket ).
Before I head down into coding I want to be sure that everyone is one
the same page regarding the expected use-cases which govern the API design.
IIUC, there are two main uses of the new functionality according to
1.) run 'server_del' when 'ipa-replica-manage del' is run in domain-level 1
Right, this is for backwards compatibility(BC).
2.) during 'ipa-server-install --uninstall', 'server_del' should be
called on one of remote masters to remove the uninstalled server from
the managed topology
What I didn't get from the design document is whether the method should
have some kind of 'force' option which should bypass all topology
connectivity checks. Currently both `ipa-replica-manage del` and server
uninstaller have options which will force the removal even if it
disconnects the topology ('--force' in the former,
'--ignore-disconnected-topology' in the latter).
I would say that uninstaller should do checks in validate method
therefore the subsequent `server-del` doesn't need to do it again but it
shouldn't harm. I.e. it should follow what the user specified. If user
wants to skip (--ignore-d..-t..) then skip. If not then it will fail in
Only issue might be error state where servers have different picture of
I guess the 'server_del' method should inherit this flag so that we
retain the original functionality (for better or worse). I propose to
name this option 'ignore_topology_disconnect' because it is more
descriptive than plain 'force'.
And in BC case, `ipa-replica-manage --force` would call `server-del
I would also like to ask whether 'server_del' (which is currently
NO_CLI) should be usable also from command line.
IMO yes, it should mostly as a couterpart of `ipa-replica-manage --force
Which bring us to --clean option and what it should do...
