Abstract contract · src/common/plugin/setup/PluginUpgradeableSetup.sol

Explained in: Plugin setup

Author: Aragon X - 2022-2024

Inherits: ERC165, IPluginSetup, ProtocolVersion

An abstract contract to inherit from to implement the plugin setup for upgradeable plugins, i.e, PluginUUPSUpgradeable being deployed via the UUPS pattern (see ERC-1822 and ERC-1967).

security-contact: sirt@aragon.org

Functions ​

implementation ​

solidity
function implementation() external view returns (address)

Selector: 0x5c60da1b

Returns the plugin implementation address.

Dev: The implementation can be instantiated via the new keyword, cloned via the minimal proxy pattern (see ERC-1167), or proxied via the UUPS proxy pattern (see ERC-1822).

ReturnsTypeDescription
[0]addressThe address of the plugin implementation contract.

prepareInstallation ​

solidity
function prepareInstallation(
    address _dao,
    bytes _data
) external returns (address plugin, IPluginSetup.PreparedSetupData preparedSetupData)

Selector: 0xf10832f1

Prepares the installation of a plugin.

ParameterTypeDescription
_daoaddressThe address of the installing DAO.
_databytesThe bytes-encoded data containing the input parameters for the installation as specified in the plugin's build metadata JSON file.
ReturnsTypeDescription
pluginaddressThe address of the Plugin contract being prepared for installation.
preparedSetupDataIPluginSetup.PreparedSetupDataThe deployed plugin's relevant data which consists of helpers and permissions.

prepareUninstallation ​

solidity
function prepareUninstallation(
    address _dao,
    IPluginSetup.SetupPayload _payload
) external returns (PermissionLib.MultiTargetPermission[] permissions)

Selector: 0x9cb0a124

Prepares the uninstallation of a plugin.

ParameterTypeDescription
_daoaddressThe address of the uninstalling DAO.
_payloadIPluginSetup.SetupPayloadThe relevant data necessary for the prepareUninstallation. See above.
ReturnsTypeDescription
permissionsPermissionLib.MultiTargetPermission[]The array of multi-targeted permission operations to be applied by the PluginSetupProcessor to the uninstalling DAO.

prepareUpdate ​

solidity
function prepareUpdate(
    address _dao,
    uint16 _fromBuild,
    IPluginSetup.SetupPayload _payload
) external returns (bytes initData, IPluginSetup.PreparedSetupData preparedSetupData)

Selector: 0xa8a9c29e

Prepares the update of a plugin.

ParameterTypeDescription
_daoaddressThe address of the updating DAO.
_fromBuilduint16The build number of the plugin to update from.
_payloadIPluginSetup.SetupPayloadThe relevant data necessary for the prepareUpdate. See above.
ReturnsTypeDescription
initDatabytesThe initialization data to be passed to upgradeable contracts when the update is applied in the PluginSetupProcessor.
preparedSetupDataIPluginSetup.PreparedSetupDataThe deployed plugin's relevant data which consists of helpers and permissions.

protocolVersion ​

solidity
function protocolVersion() external pure returns (uint8[3])

Selector: 0x2ae9c600

Returns the semantic Aragon OSx protocol version number that the implementing contract is associated with.

Dev: This version number is not to be confused with the release and build numbers found in the Version.Tag struct inside the PluginRepo contract being used to version plugin setup and associated plugin implementation contracts.

ReturnsTypeDescription
[0]uint8[3]Returns the semantic Aragon OSx protocol version number.

supportsInterface ​

solidity
function supportsInterface(bytes4 _interfaceId) external view returns (bool)

Selector: 0x01ffc9a7

Checks if this or the parent contract supports an interface by its ID.

ParameterTypeDescription
_interfaceIdbytes4The ID of the interface.

Errors ​

InvalidUpdatePath ​

solidity
error InvalidUpdatePath(uint16 fromBuild, uint16 thisBuild)

Thrown when an update path is not available, for example, if this is the initial build.

ParameterTypeDescription
fromBuilduint16The build number to update from.
thisBuilduint16The build number of this setup to update to.

Structs ​

PreparedSetupData ​

Inherited from IPluginSetup.

solidity
struct PreparedSetupData {
    address[] helpers;
    PermissionLib.MultiTargetPermission[] permissions;
}

SetupPayload ​

Inherited from IPluginSetup.

solidity
struct SetupPayload {
    address plugin;
    address[] currentHelpers;
    bytes data;
}
