The underlying issue was that the internalModel was not cleaning up it's destroy call and flags when being rematerialized immediately.

store.unloadRecord(record);
assert.equal(record.isDestroying, true, 'the record is destroying');
assert.equal(internalModel.currentState.stateName, 'root.empty', 'We are unloaded after unloadRecord');
store.findRecord('person', '1');

this should likely cancel the above unloadRecords's _checkForOrphanedInternalModels and unset _isDematerializing, so it can be back in a pristine place, ready for a findRecord

I think the test need to be test observable behavior over implementation details. Especially for the resurrection cases. Lots of things can go side-ways there, especially as we refactor codez.

assert.notEqual(timer, null, 'We scheduled destroy');
store.unloadRecord(record);
let newTimer = internalModel._scheduledDestroy;
assert.equal(newTimer, timer, 'We scheduled destroy only once');

is there a way for us to test the observable behavior of this rather then the implementation? Specifically, i suspect this will cause issues \w resurrection, and it should be possible to test that directly.


run(function() {
store.unloadRecord(record);
let timer = internalModel._scheduledDestroy;

we should aim to test observable behavior. This seems to tied to implementation details.

How about two calls to scheduleDestroy followed by a cancelDestroy and testing that isDestroyed is false?

yup, something like that sounds good. I just want to maximize test value.

@hjdivad would love your 👀 on this as well.

if (this._isDematerializing === true) {
this._isDematerializing = false;
run.cancel(this._scheduledDestroy);
this._scheduledDestroy = null;

Any reason to not put this outside the above if statement? I suspect always nulling this one here, will prevent us from accidentally not nulling it out sometimes.

Good catch. The intent was to avoid unnecessary work if we weren't in a state that needed to be cleaned up, but this isn't the correct check for that. Moved to just always resetting all three things.
