connection_pool/Changes.md

2.1.0

• Refactoring to better support connection pool subclasses [drbrain, #55]
• with should return value of the last expression [#59]

2.0.0

• The connection pool is now lazy. Connections are created as needed and retained until the pool is shut down. [drbrain, #52]

1.2.0

• Add with(options) and checkout(options). [mattcamuto] Allows the caller to override the pool timeout.

@pool.with(:timeout => 2) do |conn|
end

1.1.0

• New #shutdown method (simao)

  This method accepts a block and calls the block for each connection in the pool. After calling this method, trying to get a connection from the pool raises PoolShuttingDownError.

1.0.0

• #with_connection is now gone in favor of #with.

• We no longer pollute the top level namespace with our internal TimedStack class.

0.9.3

• #with_connection is now deprecated in favor of #with.

  A warning will be issued in the 0.9 series and the method will be removed in 1.0.

• We now reuse objects when possible.

  This means that under no contention, the same object will be checked out from the pool after subsequent calls to ConnectionPool#with.

  This change should have no impact on end user performance. If anything, it should be an improvement, depending on what objects you are pooling.

0.9.2

• Fix reentrant checkout leading to early checkin.

0.9.1

• Fix invalid superclass in version.rb

0.9.0

• Move method_missing magic into ConnectionPool::Wrapper (djanowski)
• Remove BasicObject superclass (djanowski)

0.1.0

• More precise timeouts and better error message
• ConnectionPool now subclasses BasicObject so method_missing is more effective.
