fix(deps): pin getrandom to the Holochain line; gate cargo bumps on wasm32 - #55
Conversation
…asm32 Auditing the seven dependabot PRs that the new CI produced turned up one that breaks the build and two configuration faults that caused it to be invisible. PR #46 breaks the wasm32 build, and every check passed ------------------------------------------------------- It bumps `getrandom` 0.3 -> 0.4 across all four rose_forest zomes. Measured: origin/main cargo check --workspace --target wasm32-unknown-unknown OK PR #46 same command FAILS error[E0425]: cannot find function `inner_u32` in module `backends` --> getrandom-0.3.4/src/lib.rs `getrandom` is not an ordinary dependency of the zomes. Each declares `getrandom = { version = "0.3", features = ["wasm_js"] }` purely to switch on the wasm backend of the getrandom that hdi/hdk already pull in -- a feature-enabling shim, which only works while it resolves to the SAME version hdi requires. `cargo tree` confirms hdi 0.7.1, hdk 0.6.1 and holochain_nonce 0.6.1 all still require 0.3.4. After the bump both 0.3.4 and 0.4.3 are in the graph, `wasm_js` applies only to 0.4.3, and 0.3.4 is left with no backend. So it is ignored alongside hdi/hdk: it moves when the Holochain line moves. Native `cargo check` passes on that PR, which is why it looks harmless. The gate could not see it -------------------------- Every check on #46 was green: green set, CodeQL, semgrep, and `cargo fmt`. `cargo fmt` does not compile anything, and `clippy`/`test` are held behind workflow_dispatch, so no job in CI compiled the zomes at all. A dependency bump that breaks the WASM build would have merged on a full green board. Added a `wasm-check` job: `cargo check --workspace --target wasm32-unknown-unknown`. It is deliberately NOT part of the clippy/test hold -- those are held because the full Holochain build and test surface is not expected to pass yet, whereas this is a type-check against the target the zomes actually ship to, and it is verified passing on main today. Two pip groups were fighting over one file ------------------------------------------- The `/` and `/ARF` entries produced #51 and #49, and BOTH edit ARF/requirements.txt -- guaranteed conflict, with the loser needing a manual rebase for no reason. The root entry already reaches that file on its own. Consolidated to a single pip entry using `directories:` for `/`, `/ARF`, and `/ARF/pwnies`. One group, one PR per cycle across the whole Python surface -- which also makes the green-set gate mean something, since the CI set and the application set now move together or not at all. Status of the other six, all green-set passing and none touching a pinned surface: #45 tryorama, #48 GitHub-owned actions (it did NOT disturb the dtolnay/rust-toolchain SHA pin), #49 and #51 python, #53 commons-gateway, #54 esbuild.

There was a problem hiding this comment.
When Compile check (wasm32) is registered as a required check—which is necessary for this job to act as the advertised merge gate—the workflow's pull_request trigger still filters to Rust-related paths at lines 33–40. GitHub will not create the required check for npm-, Python-, or documentation-only PRs, leaving those PRs pending and unable to merge; this exact failure mode is already documented in python-ci.yml lines 34–42. Run the workflow on every pull request and conditionally skip the expensive work while still producing the required status.

…check
Codex, P1, and correct. I documented this exact trap on python-ci.yml's trigger
and then reproduced it one file over.
`Compile check (wasm32)` and `Format` are meant to be required. GitHub leaves a
required check PENDING -- not passing -- when its workflow is skipped by path
filtering, so the `pull_request` paths filter would hang every PR that touches
no Rust.
Measured against the PRs actually open right now, rather than argued:
#43 26 files 0 rust-matching
#45 2 files 0
#49 2 files 0
#51 2 files 0
#53 2 files 0
#54 1 file 0
Six of seven. Every one of them would have sat pending forever the moment the
check was marked required.
Fixed the way Codex suggested, which is better than simply dropping the filter:
run on every pull request and skip the expensive work, rather than skipping the
workflow. A `changes` job diffs against the base ref and sets one output; `fmt`
and `wasm-check` always run and always report, but their toolchain setup, cargo
cache and actual cargo invocation are gated on it. A non-Rust PR gets a green
check in seconds with an explicit "No Rust changes" step saying why, and no
cache write.
The detector is plain git plus grep -- no third-party action, which matters in a
workflow whose other change this cycle was pinning a third-party action to a
SHA. Non-pull_request events (push, schedule, merge_group, workflow_dispatch)
always take the full path.
Regex verified against real paths: ARF/src/lib.rs, ARF/Cargo.toml,
ARF/Cargo.lock and .github/workflows/rust-ci.yml match; requirements-ci.txt,
docs/x.md and packages/y.py do not.
The held clippy/test/clippy-sarif jobs are untouched and still dispatch-only.

For a PR that changes only ARF/.cargo/config.toml or ARF/rust-toolchain.toml, this predicate reports rust=false, so both required checks follow their no-op success paths. This is especially risky for .cargo/config.toml: its target-specific rustflags select the getrandom WASM backend, so altering or removing them can cause the exact compilation failure this gate is intended to catch while Compile check (wasm32) remains green. Include these existing workspace control files in the detection predicate.

…ckend
Both Codex and CodeRabbit flagged the same hole independently, and it is the
worst one this gate could have had.
ARF/.cargo/config.toml contains:
[target.wasm32-unknown-unknown]
rustflags = ['--cfg', 'getrandom_backend="wasm_js"']
That flag is what makes the wasm build work at all -- the file's own comment
records the failure without it, in the same error family as the getrandom split
this PR exists to prevent. My detector reported `rust=false` for it, so both
required checks would have taken their no-op success path and reported green on
the single change most certain to break the build.
Demonstrated against the old predicate before changing it:
ARF/.cargo/config.toml MISSED
ARF/.cargo/config MISSED
ARF/rust-toolchain.toml MISSED
ARF/.rustfmt.toml MISSED
All four now match, along with the legacy unsuffixed forms. Re-verified in both
directions, including that `notes/cargo-config.toml.md` still does not match --
the pattern is anchored on path segments, not substrings.
getrandom ignore scoped to the major jump
------------------------------------------
CodeRabbit, correctly: a bare `dependency-name: getrandom` suppresses security
updates too. Only 0.4+ causes the version split; 0.3.x patch releases unify with
what hdi already requires and should keep flowing. Now `versions: [">=0.4"]`.
group-by: declined, with reasoning
-----------------------------------
CodeRabbit suggested `group-by: dependency-name` on the pip block. By its own
description that produces one PR per dependency, which is further from the
single-PR-per-cycle intent than the current setting rather than closer.
I also could not verify how Dependabot shapes PRs across `directories`, so the
comment that claimed "one PR per cycle" was over-claiming and has been corrected
to say what is actually known: the point of one entry is that ONE config owns
all three paths, so no two entries can propose conflicting edits to the same
file again. Either PR shape is conflict-free, because there is no second entry
left to conflict with.

…ll of Rust Three faults in the detector added by the previous two commits, all found in review of #55, and all of which fail in the direction that skips the required checks rather than the one that fails loudly. 1. `echo "$changed" | grep -qE ...` is a pipeline under `set -o pipefail`. `grep -q` exits at its first match; `echo` upstream then takes SIGPIPE, and pipefail turns the whole pipeline non-zero -- so the `if` selects the else branch and reports rust=false. Not theoretical: with a 400k-line file list whose FIRST entry is `ARF/x.rs`, the old form returned false on five runs out of five. Both required checks would have taken their no-op success path on a PR that does change Rust. Replaced with a here-string, which is not a pipeline. 2. `git fetch --no-tags --depth=0 ... || true` was invalid (--depth=0 is not accepted) and the `|| true` hid that. The checkout already uses fetch-depth: 0, which fetches all history for all branches, so origin/<base> is present without it. Removed, and replaced with an explicit rev-parse guard that fails the job if the base ref is somehow absent -- because "cannot compute the diff" must not resolve to rust=false. 3. The `push` path filter did not list ARF/.cargo/config.toml, rust-toolchain.toml, or the legacy/dotted spellings, so a direct push to main touching only the file that selects the wasm getrandom backend ran no Rust job at all. The push filter now mirrors the detector predicate, and a comment on each says they must stay in step. Verified: the workflow parses; the predicate returns true for .cargo/config.toml, rust-toolchain.toml, *.rs, Cargo.lock and this workflow, false for a docs-only diff and an empty diff, and true for the large-diff case that defeated the old form.

There was a problem hiding this comment.
When changes fails—for example because its explicit base-ref verification, checkout, or diff fails—GitHub Actions skips jobs that need the failed job unless they use an always() condition. Consequently, wasm-check never reaches its fallback step and is reported as skipped; skipped required checks do not block merging, so a Rust PR can bypass the advertised compile gate precisely when detection cannot decide. Run the required job with always() and fail it when needs.changes.result is not success (and apply the same protection to fmt), or make the detector itself a required check.
Useful? React with 👍 / 👎.
… passing
GitHub reports a job skipped by a conditional -- including one skipped because
a job it `needs` FAILED -- with a conclusion of Success, and a required check in
that state does not block a merge. That is the opposite of a workflow skipped by
path filtering, which stays Pending and blocks; the two are easy to conflate,
and the trigger comment at the top of this file documents only the second one.
So every failure mode of `changes` -- checkout, the base-ref guard added in the
previous commit, the diff itself -- took `fmt` and `wasm-check` down with it and
reported both as green, on exactly the PRs where detection could not decide.
Measured rather than argued. Two throwaway branches, both with `exit 1` forced
into the detector, dispatched against this workflow:
pre-fix Detect Rust changes = failure
Compile check (wasm32) = skipped <- reported Success, merges
Format (cargo fmt --check) = skipped <- reported Success, merges
post-fix Detect Rust changes = failure
Compile check (wasm32) = failure
Format (cargo fmt --check) = failure
Both required jobs now carry `if: ${{ !cancelled() }}` so a failed dependency no
longer skips them, plus a first step that fails the job when
`needs.changes.result != 'success'`. `!cancelled()` rather than `always()` so a
deliberately cancelled run still stops.
Worth noting for whoever configures branch protection: adding `Detect Rust
changes` to the required set is a reasonable belt-and-braces addition, but it is
not a substitute for this -- it is external configuration, and this file should
fail closed on its own.

What this is
An audit of the seven dependabot PRs the new CI produced, plus fixes for what the audit found: one PR breaks the build, and two configuration faults are why nothing caught it.
PR #46 breaks the wasm32 build — and every check on it is green
It bumps
getrandom0.3 → 0.4 across all four rose_forest zomes.Why.
getrandomis not an ordinary dependency of the zomes. Each one declarespurely to switch on the wasm backend of the
getrandomthathdi/hdkalready pull in. It is a feature-enabling shim, and it only works while it resolves to the same version hdi requires.cargo treeconfirms the requirement is still 0.3.4:After the bump both 0.3.4 and 0.4.3 are in the graph,
wasm_jsapplies only to 0.4.3, and 0.3.4 is left with no backend at all.Native
cargo checkpasses on that PR, which is exactly why it looks harmless.getrandomis now ignored alongsidehdi/hdk/holochain_serialized_bytes. It moves when the Holochain line moves, not before.The gate could not see it
Every check on #46 passed — green set, CodeQL, semgrep,
cargo fmt. But:cargo fmtdoes not compile anythingclippyandtestare held behindworkflow_dispatchSo no job in CI compiled the zomes at all. A dependency bump that breaks the WASM build would have merged on a full green board.
Added a

It is deliberately not part of the clippy/test hold: those are held because the full Holochain build and test surface is not expected to pass yet, whereas this is a type-check against the target the zomes actually ship to.
