1. A non-transitory computer-readable medium to store instructions, which when executed by a computer, cause the computer to perform operations comprising:
store a change committed by a user in a version control system; generate a cryptographic hash value based on a set of parameters corresponding to the user and a version; store the cryptographic hash value along with the change committed by the user, wherein the cryptographic hash value is associated with the change committed by the user by a redirection pointer, and the redirection pointer is stored in a database separated from the version control system; receive a request to disassociate the change committed by the user from the user; based on the received request, delete the redirection pointer from the database to disassociate the change committed by the user from the cryptographic hash value. |
