Overview

cargo-geiger ☢️

A program that lists statistics related to the usage of unsafe Rust code in a Rust crate and all its dependencies.

This cargo plugin were originally based on the code from two other projects: https://github.com/icefoxen/cargo-osha and https://github.com/sfackler/cargo-tree.

Installation

Try to find and use a system-wide installed OpenSSL library:

cargo install cargo-geiger

Or, build and statically link OpenSSL as part of the cargo-geiger executable:

cargo install cargo-geiger --features vendored-openssl

Usage

Navigate to the same directory as the Cargo.toml you want to analyze.
cargo geiger

Output example

Why even care about unsafe Rust usage?

When and why to use unsafe Rust is out of scope for this project; it is simply a tool that provides information to aid auditing and hopefully to guide dependency selection. It is, however, the opinion of the author of this project that libraries choosing to abstain from unsafe Rust usage when possible should be promoted.

This project is an attempt to create pressure against unnecessary usage of unsafe Rust in public Rust libraries.

Why the name?

https://en.wikipedia.org/wiki/Geiger_counter

Unsafe code, like ionizing radiation, is unavoidable in some situations and should be safely contained!

Known issues

Unsafe code inside macros is not detected. Needs macro expansion(?).
Unsafe code generated by build.rs is probably not detected.
More on the GitHub issue tracker.

Roadmap

~~There should be no false negatives. All unsafe code should be identified.~~ This is probably too ambitious, but scanning for #![forbid(unsafe_code)] should be a reliable alternative (implemented since 0.6.0). Please see the changelog.
An optional whitelist file at the root crate level to specify crates that are trusted to use unsafe (should only have an effect when placed in the project's root).

Libraries

Cargo Geiger exposes three libraries:

cargo-geiger - Unversioned and highly unstable library exposing the internals of the cargo-geiger binary. As such, any function contained within this library may be subject to change.
cargo-geiger-serde - A library containing the serializable report types
geiger - A library containing a few decoupled cargo components used by cargo-geiger

Make it available as a library?

I want to make a website that gives statistics on various crates, including unsafe usage. Naturally I immediately thought of this, but using cargo-geiger to output data and then attempting to re-parse it seems excessively hard. Would you accept a PR that refactors most of the actual work into a library crate?

I don't think I would ever really expect a stable API or such, but being able to keep all the processing in one program would be nice.

Use cargo_metadata to explore the dependency tree.

Switch out the cargo API pieces currently used for exploring the dependency graph and use https://crates.io/crates/cargo_metadata instead.

Found here: https://github.com/sfackler/cargo-tree/issues/41

This is a subtask of #69

Consider using https://crates.io/crates/krates as part of this migration.

Idea: safety badges
I want crate readme files to show their unsafe-ness.

for crates without #![forbid(unsafe_code)]

for crates with deps that lack #![forbid(unsafe_code)]

for crates with #![forbid(unsafe_code)]

Clicking on the badge would show the cargo-geiger report for that version of the crate.

Is anyone else interested in setting up something like this?

'features' flags does not work

This one:

        --features <FEATURES>     Space-separated list of features to activate
        --all-features            Activate all available features
        --no-default-features     Do not activate the `default` feature

use ExampleBin by default for example target

This fixes a a part of test failure in #193 - at the moment cargo-geiger sets CustomBuildRoot for code files in examples and as a result itertools/examples/iris.rs also is assumed to be a custom build root.

Feature: safety report in readme
I want a tool to automatically update update a safety report section in my project's readme file. Requirements:

Run cargo-geiger on the current project

Convert the report into Markdown format

Look for a # Safety Report section in Readme.md and replace it with the generated report

Advanced features:

An argument with the name of the markdown file to update

An argument with the name of the section to replace

Check the git repository, see if there's a tag at HEAD in the current branch, and include the tag in the report. This could be a separate program.

An option to include the branch name in the report.

An option to include the git commit ID in the report.

For each unsafe crate, link to a ticket about making the crate safer. So folks can easily express their desire for more safety in code and dependencies. For crates without such tickets, link to a page explaining how to file the ticket and add the link to cargo-geiger (make a PR). When crate maintainers delete tickets that ask for more safety, include a link to a ticket in a different repository. The isaacs/github repository is an example of this technique.

Emoji rendering error under rxvt-unicode which isn't fixed by --charset ascii

On a brand new cargo-geiger install (cargo install cargo-geiger producing version 0.7.2), I get the following less-than-ideal output when running cargo-geiger under a stack of rxvt-unicode and GNU screen:

--charset ascii does change the tree-view line-drawing characters (which render just fine in the default UTF-8 mode), but doesn't change the more important icons.

(I haven't checked your code but, when using the radioactive symbol emoji in your README for testing, the problem is that rxvt-unicode doesn't like U+FE0F (VARIATION SELECTOR-16))

Expose the cargo crate feature: vendored-openssl.

Fixes: #97

Is this an acceptable solution? For macOS this seems like the right choice to me. If this PR passes the CI build I'm fine with using the vendored-openssl feature for all platforms.

Manifest parse errors despite using latest version of Rust

❯ cargo build
    Finished dev [unoptimized + debuginfo] target(s) in 0.23s

❯ cargo geiger --version
cargo-geiger 0.11.3

❯ cargo geiger
error: failed to parse manifest at `C:\Path\To\Project\Cargo.toml`

Caused by:
  namespaced features with the `dep:` prefix are only allowed on the nightly channel and requires the `-Z namespaced-features` flag on the command-line

Which is odd, because namespaced features has been stable since 1.60 and none of the other cargo tools I have are choking on my Cargo.toml.

it would be useful to get at least the line number in the .toml file that causes the problem.

EDIT: I tried eliminating lines in my Cargo.toml to find the offending code, but even with my whole Cargo.toml commented I got the above error. Weird. geiger works fine in some other repos.

build(deps): bump krates from 0.11.0 to 0.12.6
Bumps krates from 0.11.0 to 0.12.6.

Release notes

Sourced from krates's releases.

Release 0.12.5

Fixed

PR#51 resolved #50 by no longer treating the feature set in the index as authoritative, but rather just merging in the keys that were not already located in the feature set from the crate itself. This would mean that features that are present in both but with different sub-features from the index will now be lost, but that can be fixed later if it is actually an issue.

Release 0.12.4

Fixed

PR#49 resolved #48 by not entering into an infinite loop in the presence of cyclic features. Oops.

Release 0.12.3

Fixed

PR#47 resolved #46 by both adding the prefer-index feature to get the actual correct feature information for a crate from the index, rather than the cargo metadata, as well as silently ignoring features that are resolved, but not available from the package manifest if the feature is not enabled.

Release 0.12.2

Fixed

PR#45 fixed a bug where optional dependencies could be pruned if their name differed from the feature that enabled them.

Added

PR#45 added Krates::direct_dependencies as a complement to Krates::direct_dependents.

Release 0.12.1

Added

PR#43 and PR#44 added Krates::direct_dependents to more easily obtain the crates that directly depend on the specified crate/node, regardless of any features in between those crates.

Release 0.12.0

Added

PR#42 added support for features, adding nodes for each unique future, and linking edges between dependencies and features themselves. This (hopefully) properly takes into account the existing ways of pruning the graph via targets, exclusions etc. It also allows the retrieval of that final feature set via Krates::get_enabled_features.

Fixed

PR#42 resolved #41 by properly pruning weak dependencies that were improperly resolved by cargo.

Changelog

Sourced from krates's changelog.

[0.12.6] - 2022-11-25

Changed

PR#52 updated cfg-expr to 0.12.

PR#52 changed Krates::search_matches and Krates::search_by_name to use impl Into<String> for the name to search, so that the lifetime of it is not paired with the graph itself.

[0.12.5] - 2022-11-08

cargo_metadata & krate coupling
Need to de-couple these and ensure they do not break between bumps...

https://dev.azure.com/cargo-geiger/cargo-geiger/_build/results?buildId=819&view=logs&j=022b0a5d-2698-5f72-7610-a845972a8b4c&t=33e4d865-0676-5964-ba63-59b88208e67d&l=350

Adds the `filter_target` flag when gathering cargo metadata.
Unless building for all targets is specified, --filter_target will be added to the cargo command. The target is chosen as follows:

If the user specified a target, that target is used

Otherwise, attempt to invoke rustc and determine the default target

If all else fails, build all targets.

Similar to: https://github.com/rust-lang/rust-analyzer/pull/6912

Features flags do not work as expected
If I put some unsafe usage behind a (not default) feature flag:

#[cfg(feature = "foo")] pub mod foo { pub fn bar() -> &'static [i32] { let address = 0x01234usize; let r = address as *mut i32; unsafe { std::slice::from_raw_parts_mut(r, 10000) } } }

And then run cargo geiger, it is showing use of an unsafe expression. Due to the presence of all-features and features flags for cargo-geiger, I would have expected this usage to be not be reported, unless I ran cargo-geiger with --all-features or --features foo. Am I missing something?

Cargo geiger doesnt take into account [[bin]] and [lib] properties in Cargo.toml
I have a library that does not live in "/src/lib.rs" and cargo-geiger chokes with:

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Io(Os { code: 2, kind: NotFound, message: "No such file or directory" }, "/<redacted>/src/lib.rs")', /home/<redacted>/.cargo/registry/src/github.com-1ecc6299db9ec823/cargo-geiger-0.11.2/src/scan/default.rs:106:59

Also passing the library name as parameter to the --package flag does not help.

ps: After running cargo clean the problem is resolved. I have a shared target directory with CARGO_TARGET_DIR pointing to a ramdisk. That seems to provoke this. Feel free to close if that is not supported behavior.
