creating all databases mutates the connection pool. This patch restores
the connection pool to the connection spec established before creating
all databases. Fixes #23279
|
|
|
|
|
|
| |
The error message has become a `DISABLE_DATABASE_ENVIRONMENT_CHECK`, modified to match the error message.

Prevent destructive action on production database

Raise an error when a destructive action is made on a database where the current environment is different from the environment stored in the database.
|

This PR introduces a key/value type store to Active Record that can be used for storing internal values. It is an alternative implementation to #21237 cc @sgrif @matthewd.
It is possible to run your tests against your production database by accident right now. While infrequently, but as an anecdotal data point, Heroku receives a non-trivial number of requests for a database restore due to this happening. In these cases the loss can be large.
To prevent against running tests against production we can store the "environment" version that was used when migrating the database in a new internal table. Before executing tests we can see if the database is a listed in `protected_environments` and abort. There is a manual escape valve to force this check from happening with environment variable `DISABLE_DATABASE_ENVIRONMENT_CHECK=1`.

* If the drop task fails for a reason other than the database not
existing, processing should end. This is indicated by a non-zero
exit status.
* Since the backtrace is already printed to screen, we forgo
printing it again by using an explicit call to `exit`.
* :warning: This modifies the behavior of the db:create task slightly in
that the stack trace is no longer printed by default. If the `--trace`
option is used, it will print the trace _after_ the error message.

The focus of this change is to make the API more accessible.
References to method and classes should be linked to make it easy to
navigate around.
This patch makes exzessiv use of `rdoc-ref:` to provide more readable
docs. This makes it possible to document `ActiveRecord::Base#save` even
though the method is within a separate module
`ActiveRecord::Persistence`. The goal here is to bring the API closer to
the actual code that you would write.
This commit only deals with Active Record. The other gems will be
updated accordingly but in different commits. The pass through Active
Record is not completely finished yet. A follow up commit will change
the spots I haven't yet had the time to update.

Closes #17945
`db:test:prepare` still purges the database to always keep the test
database in a consistent state.
This patch introduces new problems with `db:schema:load`. Prior
to the introduction of foreign-keys, we could run this file against
a non-empty database. Since every `create_table` containted the
`force: true` option, this would recreate tables when loading the schema.
However with foreign-keys in place, `force: true` wont work anymore and
the task will crash.

The current style for warning messages without newlines uses
concatenation of string literals with manual trailing spaces
where needed.
Heredocs have better readability, and with `squish` we can still
produce a single line.
This is a similar use case to the one that motivated defining
`strip_heredoc`, heredocs are super clean.

Closes #16757.
Prior to this patch schema loading rake tasks had the potential to leak a
connection to a different database. This had side-effects when rake tasks
operating on the current connection (like `db:seed`) were chained.

Using heredoc would enforce line wrapping to whatever column width we decided to
use in the code, making it difficult for the users to read on some consoles.
This does make the source code read slightly worse and a bit more error-prone,
but this seems like a fair price to pay since the primary purpose for these
messages are for the users to read and the code will not stick around for too
long.

The rake tasks and the `DatabaseTakss` adapter classes used to
assume a configuration at some places. This forced the rake
tasks to establish a specific connection before calling into
`load_schema`.
After #15394 this started to cause issues because it could
`purge` the wrong database before loading the schema.

* Move check from generated helper to test_help.rb, so that all
applications can benefit
* Rather than just raising when the test schema has pending migrations,
try to load in the schema and only raise if there are pending
migrations afterwards
* Opt out of the check by setting
config.active_record.maintain_test_schema = false
* Deprecate db:test:* tasks. The test helper is now fully responsible
for maintaining the test schema, so we don't need rake tasks for this.
This is also a speed improvement since we're no longer reloading the
test database on every call to "rake test".

This commit also cleans up the rake tasks that were checking
for DATABASE_URL in different places.
In fact, it would be nice to deprecate DATABASE_URL usage in the long
term, considering the direction we are moving of allowing those in .yml
files.

* A non-zero exit status allows subsequent shell commands to be chained
together such as: `rake db:reset test:prepare && rspec && cap deploy`
(if you're feeling brave :)
* Any exceptions raised during the `create` and `drop` tasks are caught
in order to print a "pretty" message to the user. Unfortunately doing
so prevents rake from aborting with a non-zero exit status to the shell.
* Therefore we re-raise the exceptions after the "pretty" message and
re-catch them in the task.
* From the task we explicitly exit with a non-zero status. This method
was chosen (rather than just letting rake fail from the exception) so
that the backtrace is suppressed and the output to stderr is
unchanged.
* Update activerecord CHANGELOG

It's simpler to assume that passed env is just a string without any
extensions, especially when DatabaseTasks are intended to be used also
without rails.
