Chainlink Functions package
This package is an contains the comands necessary for interacting with the Chainlink Functions contracts
Handling contract updates
Whenever a contract is changed, the ABI and build must be updated this Gauntlet package.
Prerequisites:
First, ensure that Foundry is installed
In your local environment set the following environment variable to tell Foundry to use the Functions profile:
export FOUNDRY_PROFILE=functions
To update an ABI:
- From the @chainlink repository go to
/contracts
. - Run
forge build
- In the folder
./contracts/foundry-artifacts/<contract name>/<contract name>.json
there will be artifacts. Find the relevant contracts and copy the ABI.
To regenerate the FunctionsContracts.build.json
file:
- From the @chainlink repository go to
/contracts
. - In
foundry.toml
the[profile.functions]
temporarily updatetest
to point only to the
test = 'src/v0.8/functions/tests/v1_X/testhelpers/FunctionsClientUpgradeHelper.sol'
- Run:
forge build --build-info --build-info-path=./info
- You will notice a new folder in
./contracts/info
. Verify that it looks as expected, then copy the contents intoFunctionsContracts.build.json
*If using Linux, remove the .Linux.gcc
suffix from the end of the field "solcLongVersion"
Using a local build
There are scenarios such as when testing new code or deploying to a staging DON that you may want to make changes and use them through the Gauntlet package.
The proper way to do this would be:
- Make experimental changes
- Bump the version here in
gauntlet-evm
's@chainlink/evm-gauntlet-functions
package.json - Run
yarn build
from thegauntlet-evm
respository - Now in the
gauntlet
repository link local package version usingnpm link [path to gauntlet-evm's @chainlink/evm-gauntlet-functions package.json]
- Change
gauntlet
's package.json to depend on the local version that was bumped to ingauntlet-evm
's@chainlink/evm-gauntlet-functions
package.json - Run
yarn install
from thegauntlet
repository - Run
yarn build
from thegauntlet
repository - To verify, the
gauntlet
repository'snode_modules
should have@chainlink/evm-gauntlet-functions
with the version that you set locally and runningnpm ls -g
should show the local package version - Now that the packages are linked any hot changes to
gauntlet-evm
can be reloaded by runningyarn build
ingauntlet-evm
and then again ingauntlet
