7-8: Workspace-level wasm_js cfg looks good; minor quoting/style nit and scope checkMoving the cfg to the top-level target is the right direction. Two nits:
- Use single-quoted TOML to avoid inner escapes.
- Confirm this broad workspace-level cfg is intended for all crates when building for wasm32-unknown-unknown (it will apply to all members and their deps for that target).
Apply within this hunk:
-[target.wasm32-unknown-unknown] -rustflags = ["--cfg=getrandom_backend=\"wasm_js\""] +[target.wasm32-unknown-unknown] +rustflags = ['--cfg=getrandom_backend="wasm_js"']common/Cargo.toml (1)
39-41: Double-check getrandom feature name; likely unnecessary/incorrect herePlease verify that getrandom provides a feature literally named "wasm_js". If not, this will fail or be a no-op; the backend selection is already driven by the cfg you added via rustflags. If the cfg is sufficient (it usually is), drop the feature and possibly the whole target-specific dep block to avoid confusion/duplication with the global getrandom dep on Line 22.
Option A — keep the block but remove the feature:
[target.'cfg(all(target_arch = "wasm32", not(target_os = "wasi")))'.dependencies] -getrandom = { workspace = true, features = ["wasm_js"] } +getrandom = { workspace = true }Option B — remove the redundant block entirely (global dep already exists):
-[target.'cfg(all(target_arch = "wasm32", not(target_os = "wasi")))'.dependencies] -getrandom = { workspace = true, features = ["wasm_js"] }Also, if the workspace isn’t on Cargo feature resolver = "2", consider enabling it at the workspace root to prevent unintended feature unification across targets.

Ah, actually - that test failure is why the config is the way it is. Putting it in the top level means js gets selected even when we're not compiling wasm for browser. |

Hmm, true. I guess that should be enabled by a js feature flag that common exposes.

🛠️ Refactor suggestion
Avoid double-enabling getrandom’s JS backend; rely on common’s feature only.
wasmbind currently enables both rustpython-common/wasm_js and getrandom/wasm_js. Due to feature unification this is redundant and risks confusion about the single source of truth. Drop the direct getrandom/wasm_js from vm and let common own it.
Apply:
-wasmbind = ["rustpython-common/wasm_js", "chrono/wasmbind", "getrandom/wasm_js", "wasm-bindgen"] +wasmbind = ["rustpython-common/wasm_js", "chrono/wasmbind", "wasm-bindgen"]
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
| wasmbind = ["rustpython-common/wasm_js", "chrono/wasmbind", "getrandom/wasm_js", "wasm-bindgen"] | |
| wasmbind = ["rustpython-common/wasm_js", "chrono/wasmbind", "wasm-bindgen"] |
In vm/Cargo.toml around line 27, the wasmbind feature list currently includes
both "rustpython-common/wasm_js" and "getrandom/wasm_js"; remove
"getrandom/wasm_js" from the vm crate's wasmbind feature so the getrandom JS
backend is provided only via rustpython-common's wasm_js feature, leaving
wasmbind = ["rustpython-common/wasm_js", "chrono/wasmbind", "wasm-bindgen"]
(ensure no other references to getrandom/wasm_js remain in this feature).
💡 Verification agent
Do not enable browser/wasm bindings by default; this likely caused the test failures.
default = ["compiler", "wasmbind", "stdio"] means native builds also activate wasmbind, which (transitively) opts into the JS randomness backend. Make wasmbind opt‑in only.
Apply:
-default = ["compiler", "wasmbind", "stdio"] +default = ["compiler", "stdio"]
Quick checks:
🏁 Script executed:
#!/bin/bash # 1) Confirm default features no longer include wasmbind rg -nP '^\s*default\s*=\s*\[.*wasmbind' -g 'vm/Cargo.toml' # 2) Ensure no other crate pulls wasmbind by default rg -nP '\bfeatures\b.*wasmbind' -C2 -g '!**/target/**' # 3) Inspect .cargo/config.* to ensure any `--cfg getrandom_backend="wasm_js"` is target-scoped to wasm32 only rg -nP --hidden -C2 'getrandom_backend\s*=\s*"wasm_js"|--cfg\s+getrandom_backend' -g '.cargo/**'

Remove wasmbind from default features in vm/Cargo.toml
vm/Cargo.toml:13 currently enables wasmbind in default features, which pulls in the JS getrandom backend for native builds — make wasmbind opt‑in.
Apply:
-default = ["compiler", "wasmbind", "stdio"] +default = ["compiler", "stdio"]
Also ensure any .cargo/config.* or --cfg getrandom_backend="wasm_js" entries are target‑scoped to wasm32 and that no other crate exposes wasmbind in its default features.
Committable suggestion skipped: line range outside the PR's diff.
In vm/Cargo.toml around line 27, remove "wasmbind" from the default features
list so the getrandom wasm_js backend is not pulled into native builds; instead
add a separate optional feature (e.g., wasmbind) that includes the wasmbind deps
and mark those dependencies as optional under that feature so wasm support is
opt‑in. Also audit any .cargo/config.* files and Cargo command args and make
sure any --cfg getrandom_backend="wasm_js" or equivalent settings are restricted
to the wasm32 target (or moved into target."cfg(target_arch = \"wasm32\")"
sections), and verify no other crate in the workspace exposes wasmbind in its
default-features so the change actually prevents native pulls.
