# crates.io. Along the way it also ensures there are no circular dependencies
# that would cause a |cargo publish| to fail.

# On success an ordered list of Cargo.toml files is written to stdout

# Consider a situation where a crate now wants to use already existing
# developing-oriented library code for their integration tests and benchmarks,
# like creating malformed data or omitting signature verifications. Ideally,
# the code should have been guarded under the special feature
# `dev-context-only-utils` to avoid accidental misuse for production code path.
#
# In this case, the feature needs to be defined then activated for the crate
# itself. To that end, the crate actually needs to depend on itself as a
# dev-dependency with `dev-context-only-utils` activated, so that the feature
# is conditionally activated only for integration tests and benchmarks. In this
# way, other crates won't see the feature activated even if they normal-depend
# on the crate.
#
# This self-referencing dev-dependency can be thought of a variant of
# dev-dependency cycles and it's well supported by cargo. The only exception is
# when publishing. In general, cyclic dev-dependency doesn't work nicely with
# publishing: https://github.com/rust-lang/cargo/issues/4242 .
#
# However, there's a work around supported by cargo. Namely, it will ignore and
# strip these cyclic dev-dependencies when publishing, if explicit version
# isn't specified: https://github.com/rust-lang/cargo/pull/7333 (Released in
# rust 1.40.0: https://releases.rs/docs/1.40.0/#cargo )
#
# This script follows the same safe discarding logic to exclude these
# special-cased dev dependencies from its `dependency_graph` and further
# processing.
