i fixed the unexpected cfg condition value: bpf-entrypoint

[victorchukwuemeka]

Summary

Adds the missing bpf-entrypoint feature to the SDK's Cargo.toml.

Problem

The documentation examples in src/entrypoint/mod.rs and src/entrypoint/lazy.rs reference a bpf-entrypoint feature that didn't exist in Cargo.toml, causing doctest warnings:

warning: unexpected `cfg` condition value: `bpf-entrypoint`
  --> sdk/src/entrypoint/mod.rs:80:7

Solution

Added bpf-entrypoint = [] to the [features] section in sdk/Cargo.toml.

Testing

• ✅ cargo test --workspace passes without warnings
• ✅ Doctests now compile successfully

@victorchukwuemeka alternatively you can add the next rules to the workspace

[workspace.lints.rust.unexpected_cfgs]
level = "warn"
check-cfg = [
    'cfg(target_os, values("solana"))',
    'cfg(feature, values("no-entrypoint"))',
]

The documentation examples in src/entrypoint/mod.rs and src/entrypoint/lazy.rs reference a bpf-entrypoint feature that didn't exist in Cargo.toml, causing doctest warnings:

The warnings that I see are these:

These are expected since those tests are meant to be ignored. Do you see a different output?

[febo]

We should not add the feature to the crate since it is not used here. It will be misleading to have it.

[victorchukwuemeka]

The warning was thier when I ran the test, after i added the feature, everything was resolved . Currently, if I run the test from my end, there is no warning message

[victorchukwuemeka]

This was the warning

[victorchukwuemeka]

After adding the feature

[febo]

Alright, I think I found the source of it. There are two doctests that are "tagged" with no_run: here and here.

The best way to prevent the warning this is to add:

//! # #![allow(unexpected_cfgs)]

just before the line:

//! #[cfg(feature = "bpf-entrypoint")]

[victorchukwuemeka]

Okay, let me add it now

[victorchukwuemeka]

Tried it, and the warning came back again
