Previously it was only possible to specify the location of the pidfile
for the 'rails server' command with the '-P' flag. This adds support for
specifying the pidfile using a PIDFILE env var, which can still be
overridden by the '-P' flag and with the default pidfile path unchanged.
The motivation for this feature comes from using Docker to run multiple
instances of the same rails app. When developing a rails app with
Docker, it's common to bind-mount the rails root directory in the
running container, so that changes to files are shared between the
container and the host. However, this doesn't work so well with the
pidfile and it's necessary to (remember to) add a '-P' flag to the
'rails server' command line; being able to specify this flag using an
env var would make developing with Rails+Docker a bit simpler.
This PR moves the `schema_migration` to `migration_context` so that we
can access the `schema_migration` per connection.
This does not change behavior of the SchemaMigration if you are using
one database. This also does not change behavior of any public APIs.
`Migrator` is private as is `MigrationContext` so we can change these as
needed.
We now need to pass a `schema_migration` to `Migrator` so that we can
run migrations on the right connection outside the context of a rake
task.
The bugs this fixes were discovered while debugging the issues around
the SchemaCache on initialization with multiple database. It was clear
that `get_all_versions` wouldn't work without these changes outside the
context of a rake task (because in the rake task we establish a
connection and change AR::Base.connection to the db we're running on).
Because the `SchemaCache` relies on the `SchemaMigration` information we
need to make sure we store it per-connection rather than on
ActiveRecord::Base.

When someone has a multi-db application their `ApplicationRecord` will
look like:
```ruby
class ApplicationRecord < ActiveRecord::Base
self.abstract_class = true
connects_to database: { writing: :primary, reading: :replica }
end
```
This will cause us to open 2 connections to ActiveRecord::Base's
database when we actually only want 1. This is because Rails sees
`ApplicationRecord` and thinks it's a new connection, not the existing
`ActiveRecord::Base` connection because the
`connection_specification_name` is different.
This PR changes `ApplicationRecord` classes to consider themselves the
same as the "primary" connection.
Fixes#36382
Previously, if a test worker exited early, the in-flight test it was
supposed to run wasn't reported as a failure.
If all workers exited immediately, this would be reported as ex.
Finished in 1.708349s, 39.2192 runs/s, 79.0237 assertions/s.
67 runs, 135 assertions, 0 failures, 0 errors, 2 skips
This commit validates that all workers finish running tests by ensuring
that the queue is empty after they exit. This works because we signal
the workers to exit by pushing nil onto the queue, so that there should
be a number of items left in the queue matching potentially missed
tests.
*sigh* this seems like the never ending bug. I don't love or even like
this fix but it does _work_.
Rafael suggested using `dummy_key: dummy_value` but unfortunately
that doesn't work. So we're left with checking whethere there might be
ternary type things in the content and then assuming that we want to
replace the line with a key value pair.
Technically fixes https://github.com/rails/rails/issues/36088
This is the behavior I naively expect for the operator when used with a
single digit, but it's definitely an edge case for it, and it doesn't
seem to work as expected for including prereleases.
Using >= works fine and make the intention more clear anyways.
The virtual attributes(`attachment` and `rich_text`) can't set value
with `fill_in`. So avoid using it. Once #35885 is merged, will be
modified to use it.
Also, add checking attachment attached or not for avoiding
`DelegationError` when attachment didn't attach.
* Fallback to spawn instead of fork in jruby
This commit: b342db6 introduced a `fork` fork when running the railties
tests since this is not supported in jruby we fallback to using spawn.
Fixes: https://github.com/rails/rails/issues/35900
As suggested in https://github.com/rails/rails/issues/35602#issuecomment-485833483, because we don't provide view caching and doesn't include `ActionController::Caching` for api apps, we should also avoid generating
```ruby
config.action_controller.perform_caching = true
```
for those api apps. So it won't confuse people.
**But because `perform_caching` will be `true` if not set, the behavior of the app would still be the same without these configs.**
This commit more or less undoes 9b5401f, restores autoloaded? not to
touch the descendants tracker, and autoloaded_constants because it is
documented in the guide.
Previously we were calling the `take_failed_screenshot` method in an
`after_teardown` hook. However, this means that other teardown hooks
have to be executed before we take the screenshot. Since there can be
dynamic updates to the page after the assertion fails and before we
take a screenshot, it seems desirable to minimize that gap as much as
possible. Taking the screenshot in a `before_teardown` rather than an
`after_teardown` helps with that, and has a side benefit of allowing
us to remove the nested `ensure` commented on here:
https://github.com/rails/rails/pull/34411#discussion_r232819478
With 8b4d344815655027d9f7584c0a59271dce8f1d5a, `test_required_polymorphic_belongs_to_generates_correct_model`
and `test_required_and_polymorphic_are_order_independent` are completely
same. Also, remove `required` from test name because that not passed to
generator.
This change adds the ability to run up/down for a database in a multi-db
environment.
If you have an app with a primary and animals database the following
tasks will be generated:
```
VERSION=123 rake db:migrate:up:primary
VERSION=123 rake db:migrate:up:primary
VERSION=123 rake db:migrate:down:primary
VERSION=123 rake db:migrate:up:animals
```
I didn't generate descriptions with them since we don't generate a
description for a single database application.
In addition to this change I've made it so if your application has
multiple databases Rails will raise if you try to run `up` or `down`
without a namespace. This is because we don't know which DB you want to
run `up` or `down` against unless the app tells us, so it's safer to
just block it and recommend using namespaced versions of up/down
respectively.
The output for the raise looks like:
```
You're using a multiple database application. To use `db:migrate:down`
you must run the namespaced task with a VERSION. Available tasks are
db:migrate:down:primary and db:migrate:down:animals.
```
