Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.
DSAuth
Fully updatable unobtrusive auth
Provides a flexible and updatable auth pattern which is completely separate
from application logic. By default, the auth modifier will restrict
function-call access to the including contract owner and the including
contract itself.
In addition, fine-grained function access can be controlled by specifying an
authority - a contract which implements the DSAuthority interface to define
custom access permissions.
Dappsys provides a couple of ready-made authority contracts, ds-guard and ds-roles, which can be used as authorities where updatable fine-grained permissioned auth is required.
Usage
The auth modifier provided by DSAuth triggers the internal isAuthorized
function to require that the msg.sender is authorized ie. the sender is either:
- the contract
owner; - the contract itself;
- or has been granted permission via a specified
authority.
function myProtectedFunction() auth {}API
setOwner(address owner_)
Set a new owner (requires auth)
setAuthority(DSAuthority authority_)
