Patches attached.

Also ipa-upgradeconfig part is called as a subprocess. This will be
removed after installer modifications.

This patch may cause temporal upgrade issues (corner cases), until
installer part will be finished.

If somebody will be hit by them, please use --skip-version-check for
ipactl and ipa-server-upgrade.

Regarding that option vs. --force: I think the common assumption is that --force ignores *all* non-fatal errors, but you break that assumption in ipactl. IMO --force should both ignore errors in service startup *and* skip version check, and a new option should be added to just ignore errors in service startup (e.g. --ignore-service-failures).
Originally I used --force option to skip detection, but there was objections against it on list.

However, to have option --force, which set true for both --ignore-service-failures and --skip-version-check options, might be better.


ipa-server-upgrade should probably also have --force, even if it does the same thing as --skip-version-check, again because --force is common.


This is a weird API:

+        if data_upgrade.badsyntax:
+            raise admintool.ScriptError(
+                'Bad syntax detected in upgrade file(s).', 1)
+        elif data_upgrade.upgradefailed:
+            raise admintool.ScriptError('IPA upgrade failed.', 1)
+        elif data_upgrade.modified:
+            self.log.info('Data update complete')
+        else:
+            self.log.info('Data update complete, no data were modified')

Why does not IPAUpgrade raise errors instead?

For historical reasons, I can investigate what would break this change, I will send it in separate patch.

+class IPAVersionError(Exception):
+    pass
+
+class PlatformMismatchError(IPAVersionError):
+    pass
+
+class DataUpgradeRequiredError(IPAVersionError):
+    pass
+
+class DataInNewerVersionError(IPAVersionError):
+    pass

I don't like the "IPA" in "IPAVersionError", it does not tell you much about what kind of version is that. Also data version errors should only tell you what is wrong, not how you fix it. IMO better names for these would be e.g. "UpgradeVersionError", "UpgradePlatformError", "UpgradeDataOlderVersionError", "UpgradeDataNewerVersionError". Similar for store_ipa_version and check_ipa_version.

Ok.

Why is it not an error if there is no version in check_ipa_version? IMO it should, even if you then ignore the exception most of the time.
I can raise error in that case and ignore the exception.
