From faaf1da99a8b04ff546d8df38e1c7e65177b35d7 Mon Sep 17 00:00:00 2001 From: Tomas Babej <[email protected]> Date: Thu, 10 Dec 2015 14:10:18 +0100 Subject: [PATCH] replicainstall: Make sure the enrollment state is preserved During the promote_check phase, the subsequent checks after the machine is enrolled may cause the installation to abort, hence leaving it enrolled even though it might not have been prior to the execution of the ipa-replica-install command. Make sure that ipa-client-install --uninstall is called on the machine that has not been enrolled before in case of failure during the promote_check phase. https://fedorahosted.org/freeipa/ticket/5529 --- ipaserver/install/server/replicainstall.py | 32 ++++++++++++++++++++++++++++++ 1 file changed, 32 insertions(+) diff --git a/ipaserver/install/server/replicainstall.py b/ipaserver/install/server/replicainstall.py index 97f19c7fd4b156a3a3a9fd4b87d6ce297ad2983c..6733caad8b3b159cd3c354f6933dcce797fb94cf 100644 --- a/ipaserver/install/server/replicainstall.py +++ b/ipaserver/install/server/replicainstall.py @@ -385,6 +385,34 @@ def common_cleanup(func): return decorated +def preserve_enrollment_state(func): + """ + Makes sure the machine is unenrollled if the decorated function + failed. + """ + def decorated(installer): + try: + func(installer) + except BaseException: + if installer._enrollment_performed: + uninstall_client() + raise + + return decorated + + +def uninstall_client(): + """ + Attempts to unenroll the IPA client using the ipa-client-install utility. + + An unsuccessful attempt to uninstall is ignored (no exception raised). + """ + + print("Removing client side components") + ipautil.run([paths.IPA_CLIENT_INSTALL, "--unattended", "--uninstall"], + raiseonerr=False) + + def promote_sssd(host_name): sssdconfig = SSSDConfig.SSSDConfig() sssdconfig.import_config() @@ -790,6 +818,8 @@ def ensure_enrolled(installer): # Call client install script service.print_msg("Configuring client side components") try: + installer._enrollment_performed = True + args = [paths.IPA_CLIENT_INSTALL, "--unattended"] stdin = None @@ -831,9 +861,11 @@ def ensure_enrolled(installer): "ipa-client-install returned: " + str(e)) @common_cleanup +@preserve_enrollment_state def promote_check(installer): options = installer + installer._enrollment_performed = False installer._top_dir = tempfile.mkdtemp("ipa") tasks.check_selinux_status() -- 2.5.0
