调研方向

Start with tools/build.sh and trace how the canary version is assembled and passed to npm version. Check the resulting names and their ordering for hashes containing letters, all-digit hashes, and leading-zero hashes. Done means canary identifiers preserve the full short hash and publish in chronological version order without changing the stated 21-line release behavior.

描述

comp: build/pipeline type: bug version: current (v17+)

tools/build.sh names each canary build <version>-canary.<short sha>. That causes two problems.

Details
  • npm orders canaries by their hash, not their age. A short sha containing a letter is compared as text, so the order is alphabetical.
    • 21.0.0-rc.0-canary.345726a, published 2026-09-21, ranks below 21.0.0-rc.0-canary.fb6796b, published 2026-08-20.
    • A short sha made only of digits is compared as a number, which ranks below every hash containing a letter. 11 published canaries have one.
  • An all-digit hash that starts with 0 loses the zero. npm version rewrites 21.0.0-canary.0123456 to 21.0.0-canary.123456, so the published name no longer matches the commit.
Scope

The order matters only when a version range matches canaries and nothing ranks above them, which is before a version's first release candidate. On the 21 line, the release candidates and the canaries named after them outrank every 21.0.0-canary.*, so this changes no install there.
