Hi all,
Using 1.7.9 (freshly installed 20 mins ago to confirm :) ), I am seeing a
wierd result from a gremlin query. I have minimized it to a small set of
commands, which reproduce the issue.
The problem in a nutshell is that when returning the results of ".map" in a
gremlin query, over the HTTP API, I get invalid json as a result.
I make a plocal graph database, then create a schema with the following sql
commands:
create class EmbType1
create property EmbType1.someint INTEGER
create property EmbType1.name STRING
create class FooType extends V
create property FooType.name STRING
alter property FooType.name MANDATORY=true
create property FooType.embinfo EMBEDDED EmbType1
Then doing a gremlin query of:
g.V("@class", "FooType").map
returns invalid JSON.
The problem is reproducable on my Mac with this set of commands, running
the default configuration xml (except the root password is changed to
"root"):
$ curl -X POST http://root:root@localhost:2480/database/mytest/plocal/graph
$ curl -X POST -H "Content-type: application/json"
http://admin:admin@localhost:2480/batch/mytest -d '{"operations":
[{"command": "create class EmbType1 ", "type": "cmd", "language": "sql"},
{"command": "create property EmbType1.someint INTEGER", "type": "cmd",
"language": "sql"}, {"command": "create property EmbType1.name STRING",
"type": "cmd", "language": "sql"}, {"command": "create class FooType
extends V", "type": "cmd", "language": "sql"}, {"command": "create property
FooType.name STRING", "type": "cmd", "language": "sql"}, {"command": "alter
property FooType.name MANDATORY=true", "type": "cmd", "language": "sql"},
{"command": "create property FooType.embinfo EMBEDDED EmbType1", "type":
"cmd", "language": "sql"}], "transaction": false}'
$ curl -X POST -H "Content-type: application/json"
http://admin:admin@localhost:2480/document/mytest -d '{"name": "fname1",
"@class": "FooType", "embinfo": {"someint": 42, "name": "ename1", "@class":
"EmbType1", "@type": "d"}}'
$ curl -X POST -H "Content-type: application/json"
http://admin:admin@localhost:2480/document/mytest -d '{"name": "fname2",
"@class": "FooType", "embinfo": {"someint": 42, "name": "ename2", "@class":
"EmbType1", "@type": "d"}}'
$ curl -X POST http://admin:admin@localhost:2480/command/mytest/gremlin -d
'g.V("@class","FooType").map'
The resulting json from the gremlin query is:
{"result":[{"@type":"d","@version":0,"value":[{{"@type":"d","@version":0,"@class":"EmbType1","someint":42,"name":"ename1"},"name":"fname1"},{{"@type":"d","@version":0,"@class":"EmbType1","someint":42,"name":"ename2"},"name":"fname2"}]}]}
Which is invalid, because value is a list of objects. The first member of
each object is the embedded document type without a key - specifically the
key in this case shoule be "embinfo" (as per my sql).
I'm pretty sure this is a bug, but I'm open to the idea I'm using things
improperly too, if that's the case.
