Validator Advisory: Wait for SV Quorum Before Upgrading to 0.9.0Forum

Canton FoundationShould act· Validators, FA Apps

We discovered a minor issue with 0.9.0 that is relevant to validators: If a validator upgrades to 0.9.0 before a quorum of SVs has upgraded, they may falsely determine that scan responses are not matching (i.e., there is no consensus among scans) for /v0/dso-sequencers ). This may severely impact the functionality of the validator. The…

AI Summary

Canton Foundation staff warn that a validator upgrading to Splice 0.9.0 before a quorum of Super Validators has upgraded may wrongly conclude that scan responses for /v0/dso-sequencers disagree, which can severely impair the validator until SV quorum is reached. Wait for the official "⅔ of SV nodes have upgraded" notice before upgrading.

SCU: a command can run under a package version the client was not compiled againstForum

Should act· Developers, FA Apps

One observation from running Smart Contract Upgrade on a sandbox, with the exact errors, in case it saves someone a debugging session. Setup: dpm 1.0.22, Daml SDK 3.4.11, single-participant dpm sandbox (its log banner says Starting Canton version 3.5.18 ), Daml Script 3.4.11 and the JSON API. Two versions of one package, 0.1.0 and 0.2.0,…

AI Summary

A developer documents a Smart Contract Upgrade gotcha: with no package_id_selection_preference, a participant executes the highest vetted package version, so a client compiled against an older version can have its command run under newer code and then fail to decode the result.
