* Support for partial inserts.Jon Leighton2012-09-281-0/+25
| | | | | | | | | | | When inserting new records, only the fields which have been changed from the defaults will actually be included in the INSERT statement. The other fields will be populated by the database. This is more efficient, and also means that it will be safe to remove database columns without getting subsequent errors in running app processes (so long as the code in those processes doesn't contain any references to the removed column).

* Support for specifying transaction isolation levelJon Leighton2012-09-211-0/+121
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If your database supports setting the isolation level for a transaction, you can set it like so: Post.transaction(isolation: :serializable) do # ... end Valid isolation levels are: * `:read_uncommitted` * `:read_committed` * `:repeatable_read` * `:serializable` You should consult the documentation for your database to understand the semantics of these different levels: * http://www.postgresql.org/docs/9.1/static/transaction-iso.html * https://dev.mysql.com/doc/refman/5.0/en/set-transaction.html An `ActiveRecord::TransactionIsolationError` will be raised if: * The adapter does not support setting the isolation level * You are joining an existing open transaction * You are creating a nested (savepoint) transaction The mysql, mysql2 and postgresql adapters support setting the transaction isolation level. However, support is disabled for mysql versions below 5, because they are affected by a bug (http://bugs.mysql.com/bug.php?id=39170) which means the isolation level gets persisted outside the transaction.

| | | | | | | | To avoid foreign key errors (and invalid data) in the database, when a belongs_to association is destroyed, it should also be nil'd out on the parent object.

The code remains the same, but by placing it in the AbstractAdapter, we can then overwrite it with Adapter specific methods that will help with Adapter specific data types. The goal of moving this code here is to create a new migration key for PostgreSQL's array type. Since any datatype can be an array, the goal is to have ':array => true' as a migration option, turning the datatype into an array. I've implemented this in postgres_ext, the syntax is shown here: https://github.com/dockyard/postgres_ext#arrays Adds array migration support Adds array_test.rb outlining the test cases for array data type Adds pg_array_parser to Gemfile for testing Adds pg_array_parser to postgresql_adapter (unused in this commit) Adds schema dump support for arrays Adds postgres array type casting support Updates changelog, adds note for inet and cidr support, which I forgot to add before Removing debugger, Adds pg_array_parser to JRuby platform Removes pg_array_parser requirement, creates ArrayParser module used by PostgreSQLAdapter

Fixes #3956.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This method was first seen in 045713ee240fff815edb5962b25d668512649478, and subsequently reimplemented in fb2325e35855d62abd2c76ce03feaa3ca7992e4f. According to @jeremy, this is okay to remove. He thinks it was added because at the time we didn't have much transaction state to keep track of, and he viewed it as a hack for us to track it internally, thinking it was better to ask the connection for the transaction state. Over the years we have added more and more state to track, a lot of which is impossible to ask the connection for. So it seems that this is just a relic of the passed and we will just track the state internally only.

* | | fixed support for DATABASE_URL for rake db tasksGrace Liu2012-09-111-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - added tests to confirm establish_connection uses DATABASE_URL and Rails.env correctly even when no arguments are passed in. - updated rake db tasks to support DATABASE_URL, and added tests to confirm correct behavior for these rake tasks. (Removed establish_connection call from some tasks since in those cases the :environment task already made sure the function would be called) - updated Resolver so that when it resolves the database url, it removes hash values with empty strings from the config spec (e.g. to support connection to postgresql when no username is specified).

In fact, it was using ConnectionTimeoutError internally, but then recueing and re-raising as a PoolFullError. There's no reason for this bifurcation, standardize on ConnectionTimeoutError, which is the rails2 name and still accurately describes semantics at this point. History In Rails2, ConnectionPool raises a ConnectionTimeoutError if it can't get a connection within timeout. Originally in master/rails3, @tenderlove had planned on removing wait/blocking in connectionpool entirely, at that point he changed exception to PoolFullError. But then later wait/blocking came back, but exception remained PoolFullError. Then in 02b233556377 pmahoney introduced fair waiting logic, and brought back ConnectionTimeoutError, introducing the weird bifurcation. ConnectionTimeoutError accurately describes semantics as of this point, and is backwards compat with rails2, there's no reason for PoolFullError to be introduced, and no reason for two different exception types to be used internally, no reason to rescue one and re-raise as another. Unify!
