Is name, surname and email in the Git commit history a personal information according to the coming GDPR (General Data Protection Regulation) and is there any special treatment required?
Git is a distributed system and therefore it is probably impossible to have a complete control of it - especially for opensource projects.
EDIT: It is also probably impossible to delete any information from the Git history. If the Git history contains any personal information, is it OK not being able to erase the information on request?
