File state.apply-don-t-check-for-cached-pillar-errors.patch of Package salt.26143
From 5880703551d82a68a0e2f3108878124d8ae98bf0 Mon Sep 17 00:00:00 2001 From: Alexander Graul <agraul@suse.com> Date: Tue, 25 Jan 2022 17:20:55 +0100 Subject: [PATCH] state.apply: don't check for cached pillar errors state.apply request new pillar data from the server. This done to always have the most up-to-date pillar to work with. Previously, checking for pillar errors looked at both the new pillar and the in-memory pillar. The latter might contain pillar rendering errors even if the former does not. For this reason, only the new pillar should be checked, not both. --- changelog/52354.fixed | 1 + changelog/57180.fixed | 1 + changelog/59339.fixed | 1 + salt/modules/state.py | 17 ++- .../modules/state/test_state_pillar_errors.py | 131 ++++++++++++++++++ .../pytests/unit/modules/state/test_state.py | 115 +++++---------- 6 files changed, 177 insertions(+), 89 deletions(-) create mode 100644 changelog/52354.fixed create mode 100644 changelog/57180.fixed create mode 100644 changelog/59339.fixed create mode 100644 tests/pytests/integration/modules/state/test_state_pillar_errors.py diff --git a/changelog/52354.fixed b/changelog/52354.fixed new file mode 100644 index 0000000000..af885d77fa --- /dev/null +++ b/changelog/52354.fixed @@ -0,0 +1 @@ +Don't check for cached pillar errors on state.apply diff --git a/changelog/57180.fixed b/changelog/57180.fixed new file mode 100644 index 0000000000..af885d77fa --- /dev/null +++ b/changelog/57180.fixed @@ -0,0 +1 @@ +Don't check for cached pillar errors on state.apply diff --git a/changelog/59339.fixed b/changelog/59339.fixed new file mode 100644 index 0000000000..af885d77fa --- /dev/null +++ b/changelog/59339.fixed @@ -0,0 +1 @@ +Don't check for cached pillar errors on state.apply diff --git a/salt/modules/state.py b/salt/modules/state.py index 0c3dfc3317..0027744229 100644 --- a/salt/modules/state.py +++ b/salt/modules/state.py @@ -106,18 +106,17 @@ def _set_retcode(ret, highstate=None): def _get_pillar_errors(kwargs, pillar=None): """ - Checks all pillars (external and internal) for errors. - Return an error message, if anywhere or None. + Check pillar for errors. + + If a pillar is passed, it will be checked.
