* | | | | | | | | | | | | | | Do not cache prepared statements that are unlikely to have cache hitsSean Griffin2015-10-2012-20/+69

This leads to the cache populating extremely fast in some cases, with the statements never being reused. In particular, the two problematic cases are `where(foo: [1, 2, 3])` and `where("foo = ?", 1)`. In both cases we'll end up quoting the values rather than using a bind param, causing a cache entry for every value ever used in that query. It was noted that we can probably eventually change `where("foo = ?", 1)` to use a bind param, which would resolve that case. Additionally, on PG we can change our generated query to be `WHERE foo = ANY($1)`, and pass an array for the bind param. I hope to accomplish both in the future. For SQLite and MySQL, we still end up preparing the statements anyway, we just don't cache it. The statement will be cleaned up after it is executed. On postgres, we skip the prepare step entirely, as an API is provided to execute with bind params without preparing the statement. I'm not 100% happy on the way this ended up being structured. I was hoping to use a decorator on the visitor, rather than mixing a module into the object, but the way Arel has it's visitor pattern set up makes it very difficult to extend without inheritance. I'd like to remove the duplication from the various places that are extending it, but that'll require a larger restructuring of that initialization logic. I'm going to take another look at the structure of it soon. This changes the signature of one of the adapter's internals, and will require downstream changes from third party adapters. I'm not too worried about this, as worst case they can simply add the parameter and always ignore it, and just keep their previous behavior. Fixes #21992.

But `t.binary ... limit: 255` is generating SQL to `varchar(255)`. It is incorrect. This commit fixes this problem.

This is what a `rewhere` does. This is undesirable behavior. The included tests demonstrate both the `unscope(...).where(...)` behavior as well as the direct use of `rewhere(...)`. This is in reference to #21955.

However, `helper` memoizes the value of `ApplicationController#helpers`. This means that if a user subsequently changes helper code and calls `reload!` in the console, their code changes will not be reflected by the `helper` function, even though the helper was, in fact, reloaded.

Switching to the slightly more verbose but less allocatey `each_pair` eliminates array allocations. Eliminating this allocation returns AR objects to have constant array allocations regardless of the number of columns the object has. Here is test code: ```ruby require 'active_record' class Topic < ActiveRecord::Base end 20.times do |i| Process.waitpid fork { ActiveRecord::Base.establish_connection adapter: 'sqlite3', database: ':memory:' ActiveRecord::Base.connection.instance_eval do create_table(:topics) do |t| t.string :title, limit: 250 t.string :author_name t.string :author_email_address t.string :parent_title t.string :type t.string :group i.times do |j| t.string :"aaa#{j}" end t.timestamps null: true end end ObjectSpace::AllocationTracer.setup(%i{type}) Topic.create title: "aaron" # heat cache result = ObjectSpace::AllocationTracer.trace do 10.times do |i| Topic.create title: "aaron #{i}" end end puts "#{Topic.columns.length},#{(result.find { |k,v| k.first == :T_ARRAY }.last.first / 10)}" } end ``` Before this commit: ``` 9,166 10,167 11,168 12,169 13,170 14,171 15,172 16,173 17,174 18,175 19,176 20,177 21,178 22,179 23,180 24,181 25,182 26,183 27,184 28,185 ``` After: ``` 9,157 10,157 11,157 12,157 13,157 14,157 15,157 16,157 17,157 18,157 19,157 20,157 21,157 22,157 23,157 24,157 25,157 26,157 27,157 28,157 ``` Left side is the number of columns, right is the number of allocations

Since string keys from the source hash will be frozen, and the dup'd objects are immediately dup'd and frozen on insert in to the hash, the end user will only ever see two frozen strings. Since the strings are immutable, this commit just cheats a little and reuses the immutable strings. Just to reiterate, before this commit, deep duping a hash that looks like this: `{ "foo" => "bar" }` will generate two new instances of "foo". One is created when `deep_dup` is called on "foo", and the other is created when the newly allocated "foo" string is inserted in to the hash. The user never sees the intermediate "foo", and both copies of "foo" that the user *can* access will be frozen, so in this case we just reuse the existing frozen key. The upshot is that after this change, string allocations on AR allocations become constant regardless of the number of columns the model has. ```ruby require 'active_record' class Topic < ActiveRecord::Base end 20.times do |i| Process.waitpid fork { ActiveRecord::Base.establish_connection adapter: 'sqlite3', database: ':memory:' ActiveRecord::Base.connection.instance_eval do create_table(:topics) do |t| t.string :title, limit: 250 t.string :author_name t.string :author_email_address t.string :parent_title t.string :type t.string :group i.times do |j| t.integer :"aaa#{j}" end t.timestamps null: true end end ObjectSpace::AllocationTracer.setup(%i{type}) Topic.create title: "aaron" # heat cache result = ObjectSpace::AllocationTracer.trace do 10.times do |i| Topic.create title: "aaron #{i}" end end puts "#{Topic.columns.length},#{(result.find { |k,v| k.first == :T_STRING }.last.first / 10)}" } end ``` If you run the above script before this commit, the output looks like this: ``` [aaron@TC rails (master)]$ be ruby -rallocation_tracer test.rb 9,105 10,107 11,109 12,111 13,113 14,115 15,117 16,119 17,121 18,123 19,125 20,127 21,129 22,131 23,133 24,135 25,137 26,139 27,141 28,143 ``` The left column is the number of methods, the right column is the number of string allocations. Running against this commit, the output is: ``` [aaron@TC rails (master)]$ be ruby -rallocation_tracer test.rb 9,87 10,87 11,87 12,87 13,87 14,87 15,87 16,87 17,87 18,87 19,87 20,87 21,87 22,87 23,87 24,87 25,87 26,87 27,87 28,87 ``` As you can see, there is now only a constant number of strings allocated, regardless of the number of columns the model has.
