Abstract
Resources, like source code, can be stored in a repository and managed through a resource repository system. The resource repository system includes a processor and a memory for storing a plurality of data structures, each data structure comprising a current version of a corresponding resource and at least one past version of the corresponding resource. The processor is communicatively coupled to the memory and configured to: request a transaction on a resource of a repository; create a snapshot of the repository; perform reads and/or writes of the transaction against the snapshot; evaluate potential conflicts between concurrently committed transactions; if no conflict is found, commit the transaction by persisting it to a write-ahead log; and update the repository based on the write-ahead log.
