Don't add `RAILS_ENV` in generate action
|
| |
| |
| |
| |
| |
| |
| | |
In the case of generator, `RAILS_ENV` is interpreted as an argument as it
is. Avoid this because it will result unintended by the user.
Fixes #34979.

The following PR adds behavior to Rails to allow an application to
automatically switch it's connection from the primary to the replica.
A request will be sent to the replica if:
* The request is a read request (`GET` or `HEAD`)
* AND It's been 2 seconds since the last write to the database (because
we don't want to send a user to a replica if the write hasn't made it
to the replica yet)
A request will be sent to the primary if:
* It's not a GET/HEAD request (ie is a POST, PATCH, etc)
* Has been less than 2 seconds since the last write to the database
The implementation that decides when to switch reads (the 2 seconds) is
"safe" to use in production but not recommended without adequate testing
with your infrastructure. At GitHub in addition to the a 5 second delay
we have a curcuit breaker that checks the replication delay
and will send the query to a replica before the 5 seconds has passed.
This is specific to our application and therefore not something Rails
should be doing for you. You'll need to test and implement more robust
handling of when to switch based on your infrastructure. The auto
switcher in Rails is meant to be a basic implementation / API that acts
as a guide for how to implement autoswitching.
The impementation here is meant to be strict enough that you know how to
implement your own resolver and operations classes but flexible enough
that we're not telling you how to do it.
The middleware is not included automatically and can be installed in
your application with the classes you want to use for the resolver and
operations passed in. If you don't pass any classes into the middleware
the Rails default Resolver and Session classes will be used.
The Resolver decides what parameters define when to
switch, Operations sets timestamps for the Resolver to read from. For
example you may want to use cookies instead of a session so you'd
implement a Resolver::Cookies class and pass that into the middleware
via configuration options.
```
config.active_record.database_selector = { delay: 2.seconds }
config.active_record.database_resolver = MyResolver
config.active_record.database_operations = MyResolver::MyCookies
```
Your classes can inherit from the existing classes and reimplment the
methods (or implement more methods) that you need to do the switching.
You only need to implement methods that you want to change. For example
if you wanted to set the session token for the last read from a replica
you would reimplement the `read_from_replica` method in your resolver
class and implement a method that updates a new timestamp in your
operations class.

We need this in order to be able to add this migration for users that
use ActiveStorage during update their apps from Rails 5.2 to Rails 6.0.

`rake app:update` should update active_storage
`rake app:update` should execute `rake active_storage:update`
if it is used in the app that is being updated.
It will add new active_storage's migrations to users' apps during update Rails.

In comments in templates for `config/database.yml`, there is a
reference to `secrets.yml` which is now deprecated.
They should be replaced with `credentials.yml` so that everyone
using latest Rails can understand.

Add `rails db:system:change` command for changing databases.
```
bin/rails db:system:change --to=postgresql
force config/database.yml
gsub Gemfile
```
The change command copies a template `config/database.yml` with
the target database adapter into your app, and replaces your database
gem with the target database gem.

When generating a new rails application (rails new) using a custom template that
includes gems from an authenticated source, the user has to provide credentials to
bundler.
One way to do this is by exporting environment variables, for example:
export BUNDLE_GITHUB__COM=user:pass: provides credentials for bundler to fetch
gems from github.com.
The problem this PR addresses is that we are currently scrubs all /BUNDLE_.*/
environment variables by wrapping our system calls in Bundler.with_clean_env.
We do this because we don't want our commands executed against the generated project
to use the generator's bundler environment (e.g. our gems): the generated project should
use it's own configuration.
The problem with Bundler.with_clean_env is that, on top of restoring environment
variables to their original state, it also scrubs any /BUNDLE_.*/ variables, which is harmful for authenticated gem sources.
This PR replaces Bundler.with_clean_env with Bundler.with_original_env, which only
restores environment variables to their initial state, without additional scrubbing.

We had a discussion on the Core team and we don't want to expose this information
as a JSON endpoint and not by default.
It doesn't make sense to expose this JSON locally and this controller is only
accessible in dev, so the proposed access from a production app seems off.
This reverts commit 8eaffe7e89719ac62ff29c2e4208cfbeb1cd1c38, reversing
changes made to b6e4305c3bca4c673996d0af9db0f4cfbf50215e.

fragment caching was refactored in (I think 5.2) and by default doesn't log cache info
this is confusing in development where rails dev:cache now turns on caching, but doesn't show any different logging output
better to enable debugging by default for dev - and let people turn it off if preferred

the machine (#34735)
* 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.
