Upgrading snforge

[iossocket]

We are working on a lending protocol that integrates pyth on Starknet and would like to use the latest versions of snforge and scarb. During the upgrading process, we found two tests failed

pyth_integrationtest::pyth::test_upgrade_works
pyth_integrationtest::pyth::test_upgrade_rejects_wrong_magic

with error message:

Failure data:
    Got an exception while executing a hint: Hint Error: Error at pc=0:20839:
Got an exception while executing a hint: Class with hash 0x042cc93b4142052d0ec7a21b6746e5fc4055a850e67881ad8590dbf9bcfb4bc7 is not declared.

The class hash in encoded in data::pyth_upgrade_fake1() and data::pyth_upgrade_wrong_magic() are not matched.

According to the README, I try to regenerate the tests/data.cairo, but the result does not include pyth_upgrade_fake1 and pyth_upgrade_wrong_magic. Did I miss something?

the repo is forked here. Thanks

I think what happened is generate_test_data crashed so it didn't generate all data for data.cairo. Looks like generate_test_data fails when it executes scarb. scarb tries to build a plugin and fails because the Rust version override for generate_test_data applies to the plugin build as well. You can fix it by updating Rust toolchain version in target_chains/starknet/tools/test_vaas/rust-toolchain from 1.78.0 to 1.86.0. After that you can run generate_test_data again and check that it finishes successfully.

Thanks a lot for your help, the test data can be generated correctly, and all tests pass.
