I have a test app that was on Ruby 2.4. When I pulled Rails master the
app no longer would boot because of this change and I saw the following
error:
```
SyntaxError:
/Users/eileencodes/open_source/real_rails/railties/lib/rails/all.rb:18:
syntax error, unexpected keyword_rescue, expecting keyword_end
rescue LoadError
^
```
Ruby 2.4 doesn't support removing redundant begins so the real issue is
that this app is on Ruby 2.4 and not on Ruby 2.5. But it's super
confusing for a user to understand the reason the app is failing to boot
is because we need Ruby 2.5.
I added this redundant begin back because we need to give a clearer
error message.
Generally followed the pattern for https://github.com/rails/rails/pull/32034
* Removes needless CI configs for 2.4
* Targets 2.5 in rubocop
* Updates existing CHANGELOG entries for fewer merge conflicts
* Removes Hash#slice extension as that's inlined on Ruby 2.5.
* Removes the need for send on define_method in MethodCallAssertions.
* Add option to set parallel test worker count to the physical core count of the machine
Also, use the physical core count of the machine as
the default number of workers, and generate the `test_helper.rb` file
with `parallelize(workers: :number_of_processors)`
Closes#34734
* Ensure that we always test parallel testing
Since #34734 we decided to use the physical core count of the machine as
the default number of workers in the parallel testing, we need to
ensure that some tests use at least 2 workers because we could
run those tests on VM that has only 1 physical core.
It also fixes tests failures on the CI since Travis server we are using
has only one physical core.
See https://travis-ci.org/rails/rails/jobs/469281088#L2352
The ActionDispatch::HostAuthorization is a new middleware that prevent
against DNS rebinding and other Host header attacks. By default it is
included only in the development environment with the following
configuration:
Rails.application.config.hosts = [
IPAddr.new("0.0.0.0/0"), # All IPv4 addresses.
IPAddr.new("::/0"), # All IPv6 addresses.
"localhost" # The localhost reserved domain.
]
In other environments, `Rails.application.config.hosts` is empty and no
Host header checks will be done. If you want to guard against header
attacks on production, you have to manually permit the allowed hosts
with:
Rails.application.config.hosts << "product.com"
The host of a request is checked against the hosts entries with the case
operator (#===), which lets hosts support entries of type RegExp,
Proc and IPAddr to name a few. Here is an example with a regexp.
# Allow requests from subdomains like `www.product.com` and
# `beta1.product.com`.
Rails.application.config.hosts << /.*\.product\.com/
A special case is supported that allows you to permit all sub-domains:
# Allow requests from subdomains like `www.product.com` and
# `beta1.product.com`.
Rails.application.config.hosts << ".product.com"
When actually execute from the command, the value of ARGV is passed to the
server. So they are String. So let's use the same type in the test.
Also, this removes the following warning in Ruby 2.6.
```
lib/rails/commands/server/server_command.rb:195: warning: deprecated Object#=~ is called on Integer; it always returns nil
```
* No need to go through ruby
* Abort early if a generator command fails
* Reuse `rails_command` method
* Bump thor minimum dependency to 0.20.3
* Add some minimal docs
* Add a changelog entry
* Restore original logging
https://www.postgresql.org/support/versioning/
- 9.1 EOLed on September 2016.
- 9.2 EOLed on September 2017.
9.3 is also not supported since Nov 8, 2018. https://www.postgresql.org/about/news/1905/
I think it may be a little bit early to drop PostgreSQL 9.3 yet.
* Deprecated `supports_ranges?` since no other databases support range data type
* Add `supports_materialized_views?` to abstract adapter
Materialized views itself is supported by other databases, other connection adapters may support them
* Remove `with_manual_interventions`
It was only necessary for PostgreSQL 9.1 or earlier
* Drop CI against PostgreSQL 9.2
Sometimes `test_scaffold_tests_pass_by_default` test fails in CI.

It seems `manifest.json` was broken.
`webpacker` will compile automatically if packs is not compiled.
If parallel test is enabled, it seems that this compilation process is
executed simultaneously in multiple processes, and it may become an
inconsistent state.
In order to avoid this, compile before running the test.
In commit 6567464bedd1e39ee7390da9484ba0caa7eb3e07 we homogenized rails
commands with former rake tasks. We decided to display all commands at
the same level and merged the list of commands displayed by `rails help`.
We however forgot to actually merge the output in the command itself.
This commit fixes that.
DRb wraps in `DRbUnknown` if the data contains a type that can not be
resolved locally. This can happen if an error occurs in the test and the
error class can not be resolved on the server side.
When this happens, an instance of `DRbUnknown` is passed to the `result`
of `Server#record`. This causes another error(undefined method assertions
for #<DRb::DRbUnknown:> (NoMethodError)) in `reporter.record`.
This can confirm by the following steps.
```
$ rails new app -B --dev; cd app
$ rails g scaffold user name:string
$ edit `config.action_controller.allow_forgery_protection = true` in environments/test.rb
$ bin/rails t
```
In the case of `DRbUnknown` occurs, can't resolve error exception. So wrap
exception with `DRbRemoteError` in the same way as an unmarshalled object.
Addressing warnings are important but it should be out of this test scope.
