* Fix cases where delete_records on a has_many association caused errorsDerek Kraan2013-01-271-0/+12
| | | | | | | | | | | | | because of an ambiguous column name. This happened if the association model had a default scope that referenced a third table, and the third table also referenced the original table (with an identical foreign_key). Mysql requires that ambiguous columns are deambiguated by using the full table.column syntax. Postgresql and Sqlite use a different syntax for updates altogether (and don't tolerate table.name syntax), so the fix requires always including the full table.column and discarding it later for Sqlite and Postgresql.

* Replace some global Hash usages with the new thread safe cache.thedarkone2012-12-141-9/+16
| | | | | | | | | | | | | | | | Summary of the changes: * Add thread_safe gem. * Use thread safe cache for digestor caching. * Replace manual synchronization with ThreadSafe::Cache in Relation::Delegation. * Replace @attribute_method_matchers_cache Hash with ThreadSafe::Cache. * Use TS::Cache to avoid the synchronisation overhead on listener retrieval. * Replace synchronisation with TS::Cache usage. * Use a preallocated array for performance/memory reasons. * Update the controllers cache to the new AS::Dependencies::ClassCache API. The original @controllers cache no longer makes much sense after @tenderlove's changes in 7b6bfe84f3 and f345e2380c. * Use TS::Cache in the connection pool to avoid locking overhead. * Use TS::Cache in ConnectionHandler.

* | Remove ActiveRecord::ModelJon Leighton2012-10-261-4/+4
|/ | | | | | | | | | 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.
* Support for partial inserts.Jon Leighton2012-09-281-1/+1
| | | | | | | | | | | 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 Leighton2012-09-212-15/+75
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

|\ | | | | Adds migration and type casting support for PostgreSQL Array datatype
| * Moves column dump specific code to a module included in AbstractAdapterDan McClain2012-09-141-0/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Having column related schema dumper code in the AbstractAdapter. 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

* | Remove our use of #outside_transaction?Jon Leighton2012-09-151-32/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
