Readme View source

gno.land/r/moul/x/upgrade/lock/v0

Version 0 of the retire the predecessor upgrade pattern (pattern B). Writable until the owner calls Retire(successor), which is one-way: from then on it is a read-only archive that names where callers should go.

See the pattern and the exploration.

Part of moul/gno-contracts — moul's versioned gno.land contracts. See the repository for the full catalog, build/test tooling, and usage.

Overview

untrusted-render: successor is the only stored string Render echoes, and Retire validates it with assertPkgPath before storing it.

Package lock is version 0 of the "retire the predecessor" upgrade pattern (pattern B of the exploration; see ../README.md).

Unlike pattern A, this version knows it can be superseded. Retire() freezes it and names its successor, and the freeze is one-way: once a successor has absorbed this version's total, re-opening it here would double-count.
