cargo-package ignores sub-directories containing Cargo.toml

[tmplt]

Problem

I am trying to publish a crate which builds adhoc crates during run-time. For this reason, I include_dir::include_dir!("assets/libadhoc"). This assets/libadhoc/ contains a Cargo.toml which is then written to disk and modified during run-time. However, on a cargo publish this directory is not copied to target/package/, even with package.include = ["*"] in the parent Cargo.toml.

Steps

$ cargo init --bin project && cd project
$ mkdir assets
$ touch assets/Cargo.toml
$ cargo package --list
Cargo.toml
src/main.rs

Possible Solution(s)

I figure **/Cargo.toml are ignored for a reason, but this is not documented in cargo-package(1). I suggest an amend.

Further, I cannot find a way to override this behavior. I suggest making that possible. Alternatively/additionally, I suggest adding an environmental variable that points to the generated target/package/project-0.1.0/ so that I can copy the files myself.

For now, I'll rename the file to not-Cargo.toml and rename it during run-time so that I can publish my crate.

Notes

Output of cargo version: cargo 1.52.0 (6976741 2021-04-21)

I'm having a similar problem with system-deps. My tests use a bunch of sub-directories containing a Cargo.toml which are not included in the package.

I think it's because cargo package does not recurse in dir containing a Cargo.toml. While it makes sense for the default, it should be overridable using the package.include field but it's not at the moment.

I'll close this in favor of #8597, as this seems a duplicate. Thank you for the input and MRE!
