ci(publish): retry a canary that collides with an npm-staged version

[filip131311]

Problem

Two canary publishes failed today: 37017742835 (0.26.1-next.11) and 37022145052 (0.26.1-next.13). Each started right after the run queued ahead of it.

npm now stages a publish and lists the version only minutes later (next.13 was PUT at 14:47:07 and listed at 14:50:24). The next run read the stale list, computed the same version and got:

npm error 409 Conflict - PUT … - Cannot publish over previously staged version "0.26.1-next.13".

The retry loop only treats a version that npm view can see as a collision. npm view couldn't see the staged version either, so the step failed as "not a version collision". Recomputing alone would also not help, because it reads the same stale list.

Fix

• publish-npm.yml: the publish output goes to publish.log through tee. A previously staged version error now counts as a collision, and set -o pipefail keeps a failed publish from looking like a success through the pipe.
• next-canary-version.mjs: new --taken <version> flag that counts the colliding version as published, so the recompute picks the next index.

Verification

• node --test scripts/next-canary-version.test.mjs passes.
• Against the live registry: no flag gives next.14, --taken 0.26.1-next.20 gives next.21, --taken 0.26.1-next.1 gives next.14.
• The loop's detection branch, run with a fake npm that prints the real E409 text, takes the collision path.

No docs update needed: this changes CI only.

📝 Walkthrough

Walkthrough

The canary publish workflow now detects staged or listed version collisions and retries with the collided version marked as taken. The version calculation script accepts the optional --taken <version> argument.

Changes

Canary Publishing

Layer / File(s)	Summary
Add taken-version input scripts/next-canary-version.mjs	The script documents --taken <version> and adds the supplied version to the list used for canary version calculation.
Retry canary version collisions .github/workflows/publish-npm.yml	The workflow captures publish output and checks for staged-version rejections or an existing version. It passes a collision to the version script and retries. Other failures remain fatal, and the three-attempt limit is unchanged.

Change: Bug fix

Merge Risk: 🟡 Moderate · up to 7bfd4

When a canary publish collides and retries, the published package can report the wrong version in telemetry. Rebuild and rerun the bundled-version check before the retry.

Systems and components

• observed — scripts (service) was modified; 1 changed file maps to changed impact.

Before / after behavior

• observed — Modified behavior in scripts/next-canary-version.mjs: The usage comment documents --taken <version> as counting a version that npm has staged but does not yet list.
• observed — Modified behavior in scripts/next-canary-version.mjs: main now appends the argument after --taken to the published-version list when the flag is present; without the flag, the list is unchanged.
• observed — Modified behavior in .github/workflows/publish-npm.yml: The comments now identify npm’s staged-version E409 rejection, which can occur before npm view sees the version, as a collision handled by recomputing; other publish failures remain fatal.
• observed — Modified behavior in .github/workflows/publish-npm.yml: The canary publish loop now captures output with tee and enables pipefail. It retries when output reports a previously staged version or npm view confirms the version exists, passing the collided version as --taken when recomputing. Other failures still exit immediately; the three-attempt limit is unchanged.

Rebuild after restamping the version.

The retry restamps package.json after the build and bundled telemetry-version check. The next publish can therefore contain bundles with the previous telemetry version. Rebuild @swmansion/argent and rerun the bundled-version check before retrying npm publish.
