Summary

#795 (chore: release v6.0.0) fails MSRV because Cargo.lock and unpublished manifests disagree.

cargo set-version 6.0.0 was only excluding clap_usage and usage-conformance. It still stamped xtask, gate, and every benches/shadows/* crate to 6.0.0. cargo update wrote those versions into Cargo.lock (which is committed). Their Cargo.toml files are not in the git add list, so they stay at 0.0.0. cargo check --locked then fails on both MSRV jobs.

Change

tasks/release-plz now excludes clap_usage and every workspace member whose version is still 0.0.0 (xtask, conformance, gate, shadows). New unpublished members are picked up automatically.

Validation

  • cargo set-version 6.0.0 -n with the new excludes upgrades only the published crates (usage-argv, usage-cli, usage-config, usage-derive, usage-lib, usage-rs, usage-test, usage-validation) and their workspace dependency entries.
  • After a real bump + cargo update (then reverted): lockfile keeps xtask / gate / shadow-mise / usage-conformance at 0.0.0; cargo check --locked -p usage-argv succeeds on the default toolchain and on 1.91.

After this merges, the next release-plz run should force-push a consistent release branch onto #795.

Summary by CodeRabbit

  • Bug Fixes
    • Release processing now preserves packages that have not yet been published while updating releasable package versions.
    • Improved version handling for workspace packages during releases.

cargo set-version stamped xtask, gate, and shadow crates to the release
version. cargo update wrote that into Cargo.lock while git add left their
manifests at 0.0.0, so MSRV cargo check --locked failed on the v6.0.0 PR.
Exclude every workspace member still at 0.0.0, plus clap_usage.

📝 Walkthrough

Walkthrough

The release script now reads offline Cargo metadata, identifies workspace packages at version 0.0.0, and excludes them from cargo set-version alongside clap_usage.

Layer / File(s) Summary
Dynamic Cargo version exclusions
tasks/release-plz
The script builds exclusions from workspace metadata. It preserves packages at version 0.0.0 while updating releasable packages.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 3272c

Release automation may continue with incomplete package exclusions if workspace metadata cannot be read, causing unpublished crates to receive release versions and leading to inconsistent manifests, lockfiles, or failed validation. Merge should wait for discovery failures to abort the operation.

Poem

I’m a rabbit with a release plan,
Skipping zeroes where I can.
clap_usage stays tucked away,
While ready crates advance today.
Cargo hops through metadata bright.

Abort when exclusion discovery fails.

At Lines 106-118, the cargo metadata | python3 pipeline runs in process substitution. Its exit status is not propagated to the surrounding while loop. If metadata lookup or JSON parsing fails, the loop completes with no dynamic exclusions, and Line 119 can modify every other 0.0.0 workspace member. Capture each command's output in a checked assignment, or use a temporary file, and exit before cargo set-version when discovery fails.

Proposed fix
 exclude_args=(--exclude clap_usage)
-while IFS= read -r pkg; do
-  exclude_args+=(--exclude "$pkg")
-done < <(
-  cargo metadata --format-version 1 --no-deps --offline | python3 -c '
