CollectingBarrierStep bug

Overriding this function seems to fix

    @Override
    public Traverser.Admin<Vertex> processNextStart() {
        try {
            return super.processNextStart();
        } catch (final NoSuchElementException e) {
            if (!this.starts.hasNext())
                throw e;
            return EmptyTraverser.instance();
        }
    }

    @Override
    public Traverser.Admin<Vertex> processNextStart() {
        try {
            return super.processNextStart();
        } catch (final NoSuchElementException e) {
            if (!this.starts.hasNext())
                throw e;
            return EmptyTraverser.instance();
        }
    }

CollectingBarrierStep bug

actual issue seems to stem from AbstractStep @Override public boolean hasNext() { if (EmptyTraverser.instance() != this.nextEnd) return true; else { try { while (true) { if (Thread.interrupted()) throw new TraversalInterruptedException(); this.nextEnd = this.processNextStart(); if (this.nextEnd.bulk() > 0) return true; else this.nextEnd = EmptyTraverser.instance(); } } catch (final NoSuchElementException e) { return false; } } } the no such element exception is producing from the collecting barrier

CollectingBarrierStep bug

found out that is not actual the offending line. Not sure what is but the statement about barrier not executing the next section is still true

Is it possible to configure SSL with PEM certificate types?

Hey @ColeGreer - I think the main problem is configuring gremlin-server in a way where it takes in a PEM file, sounds like that doesn't work and the solution is to use something like openssl to convert the PEM to PKS12. Would possibly be a nice feature to wrap that support in gremlin-server in the future but if it's not there that's fine

Potential bug in evaluationTimeout when using auth?

though you could say that the check later on should drill into the optiosn to look for it

Authorization with transaction results in error

Looks like authentication is garbling traversal arguments

Any movement on this? It seems similar to the issue I think I found

Potential bug in evaluationTimeout when using auth?

Seems like call step piece of it is irrelevant. With authentication enabled, even g.with("evaluationTimeout", X).V().next() doesnt properly set the evaluationTimeout

Traversal Inspection for properties used

I would add a way to disable it, but basically would just run it when the query comes in before I execute the actual query, so it would be accurate for the duration of that query

Traversal Inspection for properties used

g.V(<id>) would just pop out a mock vertex, out() would pop out another mock vertex, etc. I'd expect it to run inside the provider database inside a strategy, it would keeping track of what step emits which vertex and then each vertex would keep track of which property keys on it were invoked, or if all were. Then the strategy would give that info to the rest of the strategies/step replacements so they could appropriately pushdown property grabs on the vertices. Definitely a workaround

Traversal Inspection for properties used

What Valentyn mentioned about doing a wrapped element and checking what properties are used is an interesting idea. So I could potentially just execute a mock equivalent traversal (if there is no repeats and if/else logic), with fake data, and each time a step returns a vertex I attach the wrapped vertex to that step, then that wrapped vertex accumulates a list of the property keys which are invoked (or if all are called) Still might be kind of hard to do, but seems possible.

Traversal Inspection for properties used

Yeah it does in those kind of circumstances. The ideal way to have it would be that any time you collect vertices, it would know if it can optimize and pull down less than all the properties, like

g.V(<id>).out().out().toList()

g.V(<id>).out().out().toList()

Being able to tell that the first read doesn't need any properties, and the all the vertices read with the first out don't need any properties would be the goal, however the 2nd out we need all the properties. What you mentioned there is what I have right now, a strategy that inspects the traversal for HasContainers and Property steps, but also looks for labels that might mess with things, or Path steps/Tree steps that also sometimes use properties. The growing complexity is the problem, it's already hard to add more to it I am trying to find a clean way to do it but maybe there just isn't one...
