Hello,

topology disconnect/last-role-host removal errors would just be
logged
during server uninstall even if ignore options are not present. The
host
would still appear in the topology even after "successful" uninstall.

The patch seems to be ok, however shouldn't we use sys.exit() when
handling ServerRemovalError? Yes raising SystemExit from within a
function is a horrible practice, but it is already done on several
other
places instead of letting the exception bubble up to the main handler.

CC'ing Jan for his thoughts on this since I may be wrong.

Hmm, you will definitely need sys.exit() here since otherwise
ipa-server-install reports 0 exit code even if there was an exception
thrown:

"""
[root@master1 ~]# ipa-server-install --uninstall -U
ipa         : ERROR    Server removal aborted: Deleting this server
will leave your installation without a DNS..
[root@master1 ~]# echo $?
0
"""

Because of #5750 (remove sys.exit() calls from installer modules) I
rather raise ScriptError in this case. See the modified patch. It
depends on either of my 48-4 or 48-5 patches (pick one).


Make sure you raise it using str(e) because ScriptError does not
coerce the argument to string/unicode:

@@ -303,7 +303,7 @@ def
remove_master_from_managed_topology(api_instance, options):
         replication.run_server_del_as_cli(
             api_instance, api_instance.env.host, **server_del_options)
     except errors.ServerRemovalError as e:
-        raise ScriptError(e)
+        raise ScriptError(str(e))
     except Exception as e:
         # if the master was already deleted we will just get a warning
         root_logger.warning("Failed to delete master: {}".format(e))

Oops, sorry, attached is the fixed patch.
Regardless of this fix, I still get exit code 0 after exception is
raised:

"""
[root@client1 ~]# ipa-server-install --uninstall -U

DNS system.

I guess there is nothing we can do about this now as the fix for this
seems to be beyond the scope of this patch ( or am I mistaken?).

Dandy. The actual relevant ticket to zero return value no matter what is
already there - https://fedorahosted.org/freeipa/ticket/5725.


Ok then. ACK.
