* Add schema cache to new connection pool after forkEugene Kenny2015-05-171-0/+46
| | | | | | | | | | | | | | Active Record detects when the process has forked and automatically creates a new connection pool to avoid sharing file descriptors. If the existing connection pool had a schema cache associated with it, the new pool should copy it to avoid unnecessarily querying the database for its schema. The code to detect that the process has forked is in ConnectionHandler, but the existing test for it was in the ConnectionManagement test file. I moved it to the right place while I was writing the new test for this change.

* Less ambition, more deprecationMatthew Draper2014-04-091-59/+11
| | | | | | | | The "DATABASE_URL_*" idea was moving in the wrong direction. Instead, let's deprecate the situation where we end up using ENV['DATABASE_URL'] at all: the Right Way is to explicitly include it in database.yml with ERB.

* Give a deprecation message even when the lookup failsMatthew Draper2014-04-081-2/+4
| | | | | | | | | | | | If the supplied string doesn't contain a colon, it clearly cannot be a database URL. They must have intended to do a key lookup, so even though it failed, give the explanatory deprecation warning, and raise the exception that lists the known configs. Conveniently, this also simplifies our logical behaviour: if the string matches a known configuration, or doesn't contain a colon (and is therefore clearly not a URL), then we output a deprecation warning, and behave exactly as we would if it were a symbol.

* Avoid a spurious deprecation warning for database URLsMatthew Draper2014-04-031-0/+48
| | | | | | | | | | | | | | | | | | This is all about the case where we have a `DATABASE_URL`, and we have a `database.yml` present, but the latter doesn't contain the key we're looking for. If the key is a symbol, we'll always connect to `DATABASE_URL`, per the new behaviour in 283a2edec2f8ccdf90fb58025608f02a63948fa0. If the key is a string, on the other hand, it should always be a URL: the ability to specify a name not present in `database.yml` is new in this version of Rails, and that ability does not stretch to the deprecated use of a string in place of a symbol. Uncovered by @guilleiguaran while investigating #14495 -- this actually may be related to the original report, but we don't have enough info to confirm.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | If using a `DATABASE_URL` and a `database.yml`. The connection information in `DATABASE_URL` should be merged into whatever environment we are in. As released in 4.1.0rc1 if someone has a database.yml but is missing a key like production: ```yml development: host: localhost ``` Then the check for blank config will return false so the information from the `DATABASE_URL` will not be used when attempting to connect to the `production` database and the connection will incorrectly fail. This commit fixes this problem and adds a test for the behavior. In addition the ability to specify a connection url in a `database.yml` like this: ``` production: postgres://localhost/foo ``` Was introduced in 4.1.0rc1 though should not be used, instead using a url sub key ``` production: url: postgres://localhost/foo ``` This url sub key was also introduced in 4.1.0rc1 though the `production: postgres://localhost/foo` was not removed. As a result we should not test this behavior.

* Ensure Active Record connection consistencyschneems2014-01-091-0/+127
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently Active Record can be configured via the environment variable `DATABASE_URL` or by manually injecting a hash of values which is what Rails does, reading in `database.yml` and setting Active Record appropriately. Active Record expects to be able to use `DATABASE_URL` without the use of Rails, and we cannot rip out this functionality without deprecating. This presents a problem though when both config is set, and a `DATABASE_URL` is present. Currently the `DATABASE_URL` should "win" and none of the values in `database.yml` are used. This is somewhat unexpected to me if I were to set values such as `pool` in the `production:` group of `database.yml` they are ignored. There are many ways that active record initiates a connection today: - Stand Alone (without rails) - `rake db:<tasks>` - ActiveRecord.establish_connection - With Rails - `rake db:<tasks>` - `rails <server> | <console>` - `rails dbconsole` We should make all of these behave exactly the same way. The best way to do this is to put all of this logic in one place so it is guaranteed to be used. Here is my prosed matrix of how this behavior should work: ``` No database.yml No DATABASE_URL => Error ``` ``` database.yml present No DATABASE_URL => Use database.yml configuration ``` ``` No database.yml DATABASE_URL present => use DATABASE_URL configuration ``` ``` database.yml present DATABASE_URL present => Merged into `url` sub key. If both specify `url` sub key, the `database.yml` `url` sub key "wins". If other paramaters `adapter` or `database` are specified in YAML, they are discarded as the `url` sub key "wins". ``` ### Implementation Current implementation uses `ActiveRecord::Base.configurations` to resolve and merge all connection information before returning. This is achieved through a utility class: `ActiveRecord::ConnectionHandling::MergeAndResolveDefaultUrlConfig`. To understand the exact behavior of this class, it is best to review the behavior in activerecord/test/cases/connection_adapters/connection_handler_test.rb though it should match the above proposal.

* Remove ActiveRecord::ModelJon Leighton2012-10-261-2/+2
| | | | | | | | | | In the end I think the pain of implementing this seamlessly was not worth the gain provided. The intention was that it would allow plain ruby objects that might not live in your main application to be subclassed and have persistence mixed in. But I've decided that the benefit of doing that is not worth the amount of complexity that the implementation introduced.

You can also run tests directly via the command line, e.g. ruby path/to/test.rb (no rake needed, uses default db connection from test/config.yml). This will help us fix the CI by enabling us to isolate the different Rails versions to different databases.
