Major Description
Not sure what's happening but this traversal does not return any results with gremlin-python:
gremlin> g.V().hasLabel("person").has("age", P.not(P.lte(10).and(P.not(P.between(11, 20)))).and(P.lt(29).or(P.eq(35)))).values("name") ==>vadas ==>peter
When looking at the bytecode the python bytecode is different from the java bytecode. The java bytecode for the predicate is:
{
"@type": "g:P",
"@value": {
"predicate": "and",
"value": [{
"@type": "g:P",
"@value": {
"predicate": "or",
"value": [{
"@type": "g:P",
"@value": {
"predicate": "gt",
"value": {
"@type": "g:Int32",
"@value": 10
}
}
}, {
"@type": "g:P",
"@value": {
"predicate": "and",
"value": [{
"@type": "g:P",
"@value": {
"predicate": "gte",
"value": {
"@type": "g:Int32",
"@value": 11
}
}
}, {
"@type": "g:P",
"@value": {
"predicate": "lt",
"value": {
"@type": "g:Int32",
"@value": 20
}
}
}]
}
}]
}
}, {
"@type": "g:P",
"@value": {
"predicate": "or",
"value": [{
"@type": "g:P",
"@value": {
"predicate": "lt",
"value": {
"@type": "g:Int32",
"@value": 29
}
}
}, {
"@type": "g:P",
"@value": {
"predicate": "eq",
"value": {
"@type": "g:Int32",
"@value": 35
}
}
}]
}
}]
}
}
The python bytecode is:
{
"@type": "g:P",
"@value": {
"predicate": "and",
"value": [{
"@type": "g:P",
"@value": {
"predicate": "not",
"value": {
"@type": "g:P",
"@value": {
"predicate": "and",
"value": [{
"@type": "g:P",
"@value": {
"predicate": "lte",
"value": {
"@type": "g:Int64",
"@value": 10
}
}
}, {
"@type": "g:P",
"@value": {
"predicate": "not",
"value": {
"@type": "g:P",
"@value": {
"predicate": "between",
"value": [{
"@type": "g:Int64",
"@value": 11
}, {
"@type": "g:Int64",
"@value": 20
}]
}
}
}
}]
}
}
}
}, {
"@type": "g:P",
"@value": {
"predicate": "or",
"value": [{
"@type": "g:P",
"@value": {
"predicate": "lt",
"value": {
"@type": "g:Int64",
"@value": 29
}
}
}, {
"@type": "g:P",
"@value": {
"predicate": "eq",
"value": {
"@type": "g:Int64",
"@value": 35
}
}
}]
}
}]
}
}
This fix should likely be applied as part of TINKERPOP-1857 (or after it is merged) as there were a few modifications in that branch around P to resolve other issues.
