Active Record doesn't rely delegating to `arel` in the internal since
425f2ca. The delegation is a lower priority than delegating to `klass`,
so it is pretty unclear which method is delegated to `arel`.
For example, `bind_values` method was removed at b06f64c (a series of
changes https://github.com/rails/rails/compare/79f71d3...b06f64c). But a
relation still could respond to the method because `arel` also have the
same named method (#28976).
Removing the delegation will achieve predictable behavior.

kamipo/remove_method_missing_in_relation_delegation
Remove `method_missing` in `Relation::Delegation`
|
| | |
| |
| |
| | |
The `method_missing` is never reached since 64c53d7c.
|
| | |
| |
| |
| |
| | |
The delegation was needed since passing `relation` with
`relation.bound_attributes`. It should use `relation.arel` in that case.

Fix association with extension issues
|

This fixes the following issues.
* `association_scope` doesn't include `default_scope`. Should use `scope` instead.
* We can't use `method_missing` for customizing existing method.
* We can't use `relation_delegate_class` for sharing extensions. Should extend per association.

Currently `ast` and `locked` are used in the internal but delegating to
`arel` is depend on `method_missing`. If a model class is defined these
methods, `select_all` will be broken.
It should be delegated to `arel` explicitly.

Mixin `CollectionProxy::DelegateExtending` after `ClassSpecificRelation`
|
| | |
| |
| |
| |
| |
| |
| |
| |
| |
| | |
`ClassSpecificRelation` has `method_missing` and the `method_missing` is
called first. if an associated class has the missing method in a
relation, never reach to the `method_missing` in the `CollectionProxy`.
I extracted `DelegateExtending` and included it to the delegate class
that including `ClassSpecificRelation` to fix the issue.
Fixes https://github.com/rails/rails/pull/28246#issuecomment-296033784.

Follow up of 03d3f036.
Some of `respond_to?` were replaced to `respond_to_missing?` in 03d3f036.
But the visibility is still public. It should be private.

Since b644964b `ActiveRecord::Relation` includes `Enumerable` so
delegating `collect`, `all?`, and `include?` are also unneeded.
`collect` without block returns `Enumerable` without preloading by that.
We should use `load` rather than `collect` for force loading.

|

|
|
|
|

This fixes CI failure due to 48f3be8c.
`Enumerable#uniq` was introduced since Ruby 2.4. We should delegate
`uniq` to `records` explicitly.
And since b644964b `ActiveRecord::Relation` includes `Enumerable` so
delegating `map` is unneeded.

Closes #14640
|
| | |
|
| | |
|
| |
|
|
|
|
| |
Regexp#match? should be considered to be part of the Ruby core library. We are
emulating it for < 2.4, but not having to require the extension is part of the
illusion of the emulation.
|
| |
|
|
|
|
|
|
|
|
| |
This was almost every case where we are overriding `respond_to?` in a
way that mirrors a parallel implementation of `method_missing`. There is
one remaining case in Active Model that should probably do the same
thing, but had a sufficiently strange implementation that I want to
investigate it separately.
Fixes #26333.

add more array methods to straight delegation to speed up calling them

The current code base is not uniform. After some discussion,
we have chosen to go with double quotes by default.

Where appropriatei, prefer the more concise Regexp#match?,
String#include?, String#start_with?, or String#end_with?

‘set’
found these commits https://github.com/rails/rails/commit/9cc8c6f3730df3d94c81a55be9ee1b7b4ffd29f6, https://github.com/rails/rails/commit/9d79334a1dee67e31222c790e231772deafcaeb8 that also should remove it.

Clarifying this separation and enforcing relation immutability is the
culmination of the previous efforts to remove the mutator method
delegations.
|

Delegation of some `Array` methods was removed in commit 9d79334. That
change did add explicit delegation of a few methods that `Array` has but
which aren't on `Enumerable`. However, a few non-mutation methods were
omitted. This adds `Array` delegation of `#in_groups`, `#in_groups_of`,
`#shuffle` and `#split`. This allows things like
`MyThing.all.in_groups_of(3) { ... }` to continue working as they did
before commit 9d79334.

It appears that I missed this one when I delegated all the non-mutation
array methods that were not on Enumerable
|
| |
|
|
|
|
|
|
|
| |
As was pointed out by #17128, our blacklist of mutation methods was
non-exhaustive (and would need to be kept up to date with each new
version of Ruby). Now that `Relation` includes `Enumerable`, the number
of methods that we actually need to delegate are pretty small. As such,
we can change to explicitly delegating the few non-mutation related
methods that `Array` has which aren't on `Enumerable`

I wrote a utility that helps find areas where you could optimize your program using a frozen string instead of a string literal, it's called [let_it_go](https://github.com/schneems/let_it_go). After going through the output and adding `.freeze` I was able to eliminate the creation of 1,114 string objects on EVERY request to [codetriage](codetriage.com). How does this impact execution?
To look at memory:
```ruby
require 'get_process_mem'
mem = GetProcessMem.new
GC.start
GC.disable
1_114.times { " " }
before = mem.mb
after = mem.mb
GC.enable
puts "Diff: #{after - before} mb"
```
Creating 1,114 string objects results in `Diff: 0.03125 mb` of RAM allocated on every request. Or 1mb every 32 requests.
To look at raw speed:
```ruby
require 'benchmark/ips'
number_of_objects_reduced = 1_114
Benchmark.ips do |x|
x.report("freeze") { number_of_objects_reduced.times { " ".freeze } }
x.report("no-freeze") { number_of_objects_reduced.times { " " } }
end
```
We get the results
```
Calculating -------------------------------------
freeze 1.428k i/100ms
no-freeze 609.000 i/100ms
-------------------------------------------------
freeze 14.363k (± 8.5%) i/s - 71.400k
no-freeze 6.084k (± 8.1%) i/s - 30.450k
```
Now we can do some maths:
```ruby
ips = 6_226k # iterations / 1 second
call_time_before = 1.0 / ips # seconds per iteration
ips = 15_254 # iterations / 1 second
call_time_after = 1.0 / ips # seconds per iteration
diff = call_time_before - call_time_after
number_of_objects_reduced * diff * 100
# => 0.4530373333993266 miliseconds saved per request
```
So we're shaving off 1 second of execution time for every 220 requests.
Is this going to be an insane speed boost to any Rails app: nope. Should we merge it: yep.
p.s. If you know of a method call that doesn't modify a string input such as [String#gsub](https://github.com/schneems/let_it_go/blob/b0e2da69f0cca87ab581022baa43291cdf48638c/lib/let_it_go/core_ext/string.rb#L37) please [give me a pull request to the appropriate file](https://github.com/schneems/let_it_go/blob/b0e2da69f0cca87ab581022baa43291cdf48638c/lib/let_it_go/core_ext/string.rb#L37), or open an issue in LetItGo so we can track and freeze more strings.
Keep those strings Frozen

This is a regression 4.0 -> 4.1 fix.
In 4.1.0 Relation#join is delegated to Arel#SelectManager.
In 4.0 series it is delegated to Array#join
This patch puts back the behaviour of 4.0

Fixes #14752
Select mimics the block interface of arrays, but does not mock the
block interface for select!. This change moves the api to be a
private method, _select!.

This change was necessary because the whitelist wouldn't work.
It would be painful for users trying to update their applications.
This blacklist intent to prevent odd bugs and confusion in code that call mutator
methods directely on the `Relation`.

The primary means of returning results for Array bang methods is to modify
the array in-place. When you call these methods on a relation, that
array is created, modified, and then thrown away. Only the secondary
return value is exposed to the caller.
Removing this delegation is a straight-forward way to reduce user error
by forcing callers to first explicitly call #to_a in order to expose
the array to be acted on by the bang method.
