From 28e8967c290642a059e8fbceae7803a351bce2fd Mon Sep 17 00:00:00 2001 From: "Daniel A. Wozniak" Date: Sat, 13 Dec 2025 19:14:40 -0700 Subject: [PATCH] Fix #30971: Handle requisites correctly for empty SLS files Empty SLS files were not being tracked properly for requisite checking, causing 'requisite not found' errors. This fix ensures empty SLS files are processed and tracked correctly for requisite dependencies. - Added _processed_sls_files set to track processed SLS files - Track SLS files in compile_high_data even if they produce no chunks - Check _processed_sls_files when validating SLS requisites - Handle empty SLS requisites in call_chunk execution - Track SLS files in render_state and get_highstate - Added test case to test_require.py to verify the fix --- salt/state.py | 130 +++++++++++++++++- .../modules/state/requisites/test_require.py | 59 ++++++++ 2 files changed, 185 insertions(+), 4 deletions(-) diff --git a/salt/state.py b/salt/state.py index 5129b1929c40..955e05507d6a 100644 --- a/salt/state.py +++ b/salt/state.py @@ -52,7 +52,7 @@ from salt.serializers.msgpack import deserialize as msgpack_deserialize from salt.serializers.msgpack import serialize as msgpack_serialize from salt.template import compile_template, compile_template_str -from salt.utils.datastructures import DefaultOrderedDict, HashableOrderedDict +from salt.utils.odict import DefaultOrderedDict, HashableOrderedDict log = logging.getLogger(__name__) @@ -831,6 +831,8 @@ def __init__( self.inject_globals = {} self.mocked = mocked self.global_state_conditions = None + # Fix for Issue #30971: Track processed SLS files to handle empty SLS files + self._processed_sls_files = set() def _match_global_state_conditions(self, full, state, name): """ @@ -1231,8 +1233,6 @@ def _run_check_cmd(self, low_data): cmd_opts = {} if "shell" in self.opts["grains"]: cmd_opts["shell"] = self.opts["grains"].get("shell") -
