lazy/v1 package

Overview

untrusted-render: records are seeded in init or derived from lazy/v0's own init; this realm exposes no setter, so no caller string ever reaches Render.

Package lazy is version 1 of the "lazy migration" upgrade pattern (pattern D of the exploration; see ../README.md).

v1 changes the stored shape (Score widens, Active is new) and migrates one record at a time, on first touch, paid for by whoever touched it. There is no migration transaction and no pause.

The catch on today's gno: migrating on read MUTATES, so the read path has to be a crossing function. Get therefore costs a transaction and is invisible to vm/qeval and to Render. Peek is the honest read-only half, and it reports the pre-migration answer for records that have not been touched yet.

Functions

Migrated

func Migrated() int
Ask AI Claude ChatGPT

Migrated is how many records have actually moved over.

Command

gnokey query vm/qeval -remote "https://rpc.onyx.testnets.gno.land" -data "gno.land/r/nym-moultest123/x/upgrade/lazy/v1.Migrated()"

Result

Pending

func Pending() int
Ask AI Claude ChatGPT

Pending is how many v0 records have never been touched. It is only a bound: v0 keeps every record it ever had, migrated or not.

Command

gnokey query vm/qeval -remote "https://rpc.onyx.testnets.gno.land" -data "gno.land/r/nym-moultest123/x/upgrade/lazy/v1.Pending()"

Result

Render

func Render(_ string) string
Ask AI Claude ChatGPT

Param

Command

gnokey query vm/qeval -remote "https://rpc.onyx.testnets.gno.land" -data "gno.land/r/nym-moultest123/x/upgrade/lazy/v1.Render()"

Result

Get

func Get(cur realm, key string) *Record
Ask AI Claude ChatGPT

Get returns a record, migrating it from v0 on first touch.

Crossing, because the migration writes. That is the cost of the pattern: the cheapest possible read is now a transaction.

Peek

func Peek(key string) *Record
Ask AI Claude ChatGPT

Peek is the read-only half: it never migrates, so a record that has not been touched yet reads as its v0 self converted on the fly and NOT stored.

Param

Command

gnokey query vm/qeval -remote "https://rpc.onyx.testnets.gno.land" -data "gno.land/r/nym-moultest123/x/upgrade/lazy/v1.Peek()"
