* A string in the example lacked quotes.
* The tests asserted stuff about :last_name, whereas
test params do not have that key.
* But, the first one passed, why? After hitting my head against
the wall and doing some obscure rituals realized the new
#require had an important typo, wanted to iterate over the
array argument (key), but it ran over its own hash keys
(method #keys).
* Modified the test to prevent the same typo to happen again.
* The second test assigned to an unused variable safe_params
that has been therefore removed.
* Grammar of the second test description.
* Since I was on it, reworded both test descriptions.

This PR adds ability to accept arrays which allows you to require multiple values in one method. so instead of this:
```ruby
params.require(:person).require(:first_name)
params.require(:person).require(:last_name)
```
Here it will be one line for each params, so say if I require 10params, it will be 10lines of repeated code which is not dry. So I have added new method which does this in one line:
```ruby
params.require(:person).require([:first_name, :last_name])
```
Comments welcome

Apparently the AbstractController (whatever "abstract" means) is
expected to work without a request and response.
|
| |
| |
| |
| |
| | |
`render` is the only possible source for the `plain` option. Pulling
the conditional up to the `render` method removes far away conditionals
|
| |
| |
| |
| |
| |
| | |
We don't need to pass the full hash just to pull one value out. It's
better to just pass the value that the method needs to know about so
that we can abstract it away from "options"
|
| |
| |
| |
| |
| |
| | |
Since all controller instances are required to have a request and
response object, RackDelegation is no longer needed (we always have to
delegate to the response)
|
| |
| |
| |
| |
| | |
the subclass sets the body on the response object, so we don't need the
superclass doing it too
|
| |
| |
| |
| |
| |
| | |
Now that `Controller#status=` just delegates to the response object,
we don't need to set the response on the controller and the response.
We can just set it in one place.
|
| |
| |
| |
| | |
we always have a response object, so there is no reason to test it
|
| |
| |
| |
| |
| |
| |
| |
| |
| |
| | |
Controllers should always have a request and response when responding.
Since we make this The Rule(tm), then controllers don't need to be
somewhere in limbo between "asking a response object for a rack
response" or "I, myself contain a rack response". This duality leads to
conditionals spread through the codebase that we can delete:
* https://github.com/rails/rails/blob/85a78d9358aa728298cd020cdc842b55c16f9549/actionpack/lib/action_controller/metal.rb#L221-L223
|
| | |
|
| |
| |
| |
| |
| |
| | |
we don't need an instance to figure out what type of response to
allocate. Later we'll pull this up the stack and pass the response
object down

people should be accessing request information through the request
object, not via the env hash. If they really really want at the env
hash, then they can get it off the request.

The cookie jar can just ask the request object for the information it
needs. This allows us to stop allocating hashes for options, and also
allows us to delay calculating values in advance. Generating the
options hash forced us to calculate values that we may never have needed
at runtime
|
|/ /

| |
| |
| | |
Accessing a request object has nice advantages over accessing a hash.
If you use a missing method name, you'll get an exception rather than a
`nil` (is one nice feature)
|

The request.script_name is dup-d which allocates an extra string. It is most commonly an empty string "". We can save a ton of string allocations by checking first if the string is empty, if so we can use a frozen empty string instead of duplicating an empty string.
This change buys us 35,714 bytes of memory and 893 fewer objects per request.

This feature also works with `PUT`, `PATCH` and `DELETE` requests.
Also developers can add `:url_encoded_form` and `:multipart_form`
into the `:format` for wrapping url encoded or multipart form data.

there is no reason to `convert_hashes_to_parameters` with an assignemt
flag. The caller knows whether or not it wants the value assigned. We
should just change the uncommon case (not writing to the underlying
hash) to just call the conversion method and return that value.
|
| |
| |
| |
| |
| |
| | |
only hashes are converted to parameter objects, so lets add a branch for
them. This also removes a is_a? test for Parameters so we can be
abstracted from the class.

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

Fix exception overwritten for parameters fetch method

When executing an `ActionController::Parameters#fetch` with a block
that raises a `KeyError` the raised `KeyError` will be rescued and
converted to an `ActionController::ParameterMissing` exception,
covering up the original exception.

This will silence deprecation warnings.
Most of the test can be changed from `render :text` to render `:plain`
or `render :body` right away. However, there are some tests that needed
to be fixed by hand as they actually assert the default Content-Type
returned from `render :body`.

this way we don't need to call `to_unsafe_h` to get access to ask
questions about the underlying hash
|
| | |
| | |
| | |
| | | |
now `hash_filter` doesn't need to know about the `Parameters` class
|
| | |
| | |
| | |
| | |
| | | |
Since we proved that `element` is always of type `Parameter`, we know
that it will always respond to `permit`, so lets remove this conditional
