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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Here's the explanation I just sent to @tenderlove: Hey, I've been thinking about about the transaction memory leak thing that we were discussing. Example code: post = nil Post.transaction do N.times { post = Post.create } end Post.transaction is going to create a real transaction and there will also be a (savepoint) transaction inside each Post.create. In an idea world, we'd like all but the last Post instance to be GC'd, and for the last Post instance to receive its after_commit callback when Post.transaction returns. I can't see how this can work using your solution where the Post itself holds a reference to the transaction it is in; when Post.transaction returns, control does not switch to any of Post's instance methods, so it can't trigger the callbacks itself. What we really want is for the transaction itself to hold weak references to the objects within the transaction. So those objects can be GC'd, but if they are not GC'd then the transaction can iterate them and execute their callbacks. I've looked into WeakRef implementations that are available. On 1.9.3, the stdlib weakref library is broken and we shouldn't use it. There is a better implementation here: https://github.com/bdurand/ref/blob/master/lib/ref/weak_reference/pure_ruby.rb We could use that, either by pulling in the gem or just copying the code in, but it still suffers from the limitation that it uses ObjectSpace finalizers. In my testing, this finalizers make GC quite expensive: https://gist.github.com/3722432 Ruby 2.0 will have a native WeakRef implementation (via ObjectSpace::WeakMap), hence won't be reliant on finalizers: http://bugs.ruby-lang.org/issues/4168 So the ultimate solution will be for everyone to use Ruby 2.0, and for us to just use ObjectSpace::WeakMap. In the meantime, we have basically 3 options: The first is to leave it as it is. The second is to use a finalizer-based weakref implementation and take the GC perf hit. The final option is to store object ids rather than the actual objects. Then use ObjectSpace._id2ref to deference the objects at the end of the transaction, if they exist. This won't stop memory use growing within the transaction, but it'll grow more slowly. I benchmarked the performance of _id2ref this if the object does or does not exist: https://gist.github.com/3722550 If it does exist it seems decent, but it's hugely more expensive if it doesn't, probably because we have to do the rescue nil. Probably most of the time the objects will exist. However the point of doing this optimisation is to allow people to create a large number of objects inside a transaction and have them be GC'd. So for that use case, we'd be replacing one problem with another. I'm not sure which of the two problems is worse. My feeling is that we should just leave this for now and come back to it when Ruby 2.0 is out. I'm going to revert your commit because I can't see how it solves this. Hope you don't mind... if I've misunderstood then let me know! Jon

(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!
