Closes src-d/gitbase#679 Because subqueries are analyzed as if they were a whole independent query QueryProcess nodes were added to them. That caused that as soon as a subquery finished, the process were marked as done. As a result, some queries could error with "context canceled", as the context of the query had already been canceled. This fix removes the QueryProcess nodes from any subquery and makes sure only the root node is wrapped in a QueryProcess. Signed-off-by: Miguel Molina <[email protected]>
