This uses a new collector that leads to invalid expressions when using bind parameters. For example, when generating PostgreSQL queries, the bind parameter number starts from one again. When using the SubstituteBinds collector, binds in the subquery are not substituted. This commit changes the ToSql visitor to visit the SelectManager ast itself.

This makes comparision and working with the ast sometimes painful, as equality or operations likes array differences (which uses a hash behind the scene) produces unexpected results. A test has been added that ensures that every descendants of Node: * have all 3 methods * that all 3 methods were defined from the same class * that the class defining all 3 is also a descendant of Node, to avoid the default ones that rely on identity only

This is something I'd like to revert eventually, either by disabling that form of caching in that case or re-introducing something like the old `Bind` collector. The addition of `nil?` is to make `IS NULL` be inserted correctly, similar to what we already do with quoted and casted nodes
| | * | | | | | | | | | | | Add a collector to grab the bind values off the ASTSean Griffin2017-07-214-0/+143

This requires a full walk of the AST. This is an expensive operation, so I've also added a visitor for delegating to more than one visitor in a single pass.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Switching from `''.dup` to `String.new` had the side effect of changing the encoding on Ruby 2.4 and later. Oddly, `String.new(encoding: Encoding::UTF_8)` is significantly slower than `''.dup`. This seems like a bug in Ruby, but not something we're going to address right now. A test has been added to ensure this regression doesn't occur again.
| | * | | | | | | | | | | | Refactor `substitute_binds` to perform substitution immediatelySean Griffin2017-07-216-68/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I'm honestly not sure if replacing bind params with their concrete values is something that belongs in Arel at all, as it's something that will need to be coupled to the quoting mechanism of the caller, and could just be accomplished by using `Quoted` instead. Still, with the new structure we can provide a much simpler API around substitution. The expectation of the quoter responding to `quote` is a reasonably minimal API. I originally used `DelegateClass` here, with the one line override of `add_bind`, but realized that we have some funky code going on where the collector returns the next collector to use (in practice `self` is always returned, and I don't see why we'd ever want to do this). Removing that would likely be worthwhile, but would be a larger refactoring
| | * | | | | | | | | | | | Add a value field `Nodes::BindParam`Sean Griffin2017-07-2114-125/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is part of a greater refactoring to have the `BindParam` nodes hold onto their values. We want to generally keep the AST decoupled from what you're actually doing with those values, but ultimately the usage of `BindParam` is almost identical to how you'd use `Casted` or `Quoted`. Forcing consumers of Arel's API to maintain the bind values separately from the AST makes manipulating the AST essentially impossible, as you would need to perform a full walk of the AST to determine whether a given node contains bind parameters, and which value it maps to. By storing the value on the bind parameter directly, we can collect them in another AST pass (realistically it'll be part of the same pass that performs SQL construction for performance reasons). This will dramatically simplify AST manipulation for Rails or any other consumers that work with bind params. As part of this change I've removed the `BindVisitor`, which appears to be dead code, and had tests break from this change.
