Method: Rugged::Config#transaction

Defined in:

ext/rugged/rugged_config.c

#transaction {|config| ... } ⇒ Object

Perform configuration changes in a transaction.

Locks the configuration, executes the given block and stores any changes that were made to the configuration. If the block throws an exception, all changes are rolled back automatically.

During the execution of the block, configuration changes don’t get stored to disk immediately, so reading from the configuration will continue to return the values that were stored in the configuration when the transaction was started.

Yields:

• (config)
