With unique constraints in the database, the adapter fails on all but the first instance. The fix ensures that policies are still added to the in-memory model even when the adapter fails, allowing instances to stay synchronized. The behavior is: - If adapter fails but policy can be added to model => success (handles duplicates) - If adapter fails and model validation fails => return adapter error - Remove policies don't change (still require to use the current endpoint in the other library without interface changes) Co-authored-by: mserico <140243407+mserico@users.noreply.github.com> --- enforcer_context.go | 37 +++++++++++++++- error_test.go | 48 +++++++++----------- internal_api.go | 37 +++++++++++++++- watcher_unique_constraint_test.go | 73 +++++++++++++++++++++++++++++++ 4 files changed, 163 insertions(+), 32 deletions(-) diff --git a/enforcer_context.go b/enforcer_context.go index ef845b712..6b1672155 100644 --- a/enforcer_context.go +++ b/enforcer_context.go @@ -422,26 +422,40 @@ func (e *ContextEnforcer) addPolicyWithoutNotifyCtx(ctx context.Context, sec str return false, err } + var adapterErr error if e.shouldPersist() { if err = e.adapterCtx.AddPolicyCtx(ctx, sec, ptype, rule);
