Tarpaulin 0.18.0-alpha1 fails after a `cargo build`

[winksaville]

Describe the bug
When using Tarpaulin 0.18.0-alpha1 installed from a clone of this project:

wink@3900x:~/prgs/rust/clone/tarpaulin (develop)
$ git log -1 --pretty=oneline
2eb72209c908b5fe3be55cfeb2da4d723f103d2f (HEAD -> develop, origin/develop, origin/HEAD) Bump syn from 1.0.68 to 1.0.69 (#735)

wink@3900x:~/prgs/rust/projects/binance-auto-sell (tarpaulin-requires-cargo-clean)
$ cargo tarpaulin --version
cargo-tarpaulin version: 0.18.0-alpha1

I get the following error when I compile winksaville/binance-auto-sell:

warning: build failed, waiting for other jobs to finish...
thread 'main' panicked at 'already borrowed: BorrowMutError', src/tools/cargo/src/cargo/util/config/mod.rs:307:20

If instead I use the release version, 0.16.0:

wink@3900x:~/prgs/rust/projects/binance-auto-sell (tarpaulin-requires-cargo-clean)
$ cargo tarpaulin --version
cargo-tarpaulin version: 0.16.0

It completes successfully:

But note: the 0.00% coverage! Hence the reason to use 0.18.0 as it supports --follow-exec

To Reproduce

Here is the command line and full output. Notice that this happens after a cargo build:

Work-around
If I do a cargo clean before the cargo tarpaulin it works:

[xd009642]

So there was a cargo PR about this that was meant to fix it. I tried to use the latest nightly for your project with the latest nightly compiler just to make sure I was using a version of cargo with the fix in and instead I encountered ICE rust-lang/rust#84225 .

Tomorrow is the start of my weekend so I'll set aside some time to more thoroughly diff 0.16.0 and 0.18.0-alpha1 to try and see what changed and also try it out on some other projects to get to the bottom of it.

[winksaville]

@xd009642, txs for looking into this.

This evening, I'll try to simplify the code.

[winksaville]

I've simplified the code its on my tarpaulin-requires-cargo-clean branch.

main.rs is as simple as I could get:

wink@3900x:~/prgs/rust/projects/binance-auto-sell (tarpaulin-requires-cargo-clean)
$ cat src/main.rs
use clap::Clap;

#[derive(Clap)]
struct Cli {}

fn main() {
    Cli::parse(); // Fails
    //Cli {}; // Works
}

tests/cli.rs is empty

wink@3900x:~/prgs/rust/projects/binance-auto-sell (tarpaulin-requires-cargo-clean)
$ ls -al tests
total 8
drwxr-xr-x 2 wink users 4096 Apr 15 21:54 .
drwxr-xr-x 6 wink users 4096 Apr 15 22:11 ..
-rw-r--r-- 1 wink users    0 Apr 15 21:48 cli.rs

In Cargo.toml I've removed the [dev-dependencies]

wink@3900x:~/prgs/rust/projects/binance-auto-sell (tarpaulin-requires-cargo-clean)
$ cat Cargo.toml 
[package]
name = "binance-auto-sell"
version = "0.1.0"
authors = ["Wink Saville <wink@saville.com>"]
edition = "2018"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
clap = "3.0.0-beta.2"

rust-toolchain is still stable

wink@3900x:~/prgs/rust/projects/binance-auto-sell (tarpaulin-requires-cargo-clean)
$ cat rust-toolchain 
[toolchain]
channel = "stable"
components = [ "rustfmt", "rustc-dev" ]
profile = "minimal"

And tarpaulin is still 0.18.0-alpha1

wink@3900x:~/prgs/rust/projects/binance-auto-sell (tarpaulin-requires-cargo-clean)
$ cargo tarpaulin --version
cargo-tarpaulin version: 0.18.0-alpha1

And running cargo clean ; cargo build ; cargo tarpaulin still fails:

I hope this makes identifing the problem easier. Let me know if there is anything you'd like me to do!

[xd009642]

So it looks like this may have been indirectly caused by the same issue being fixed by rust-lang/rust#84226 . I'll change tarpaulin to clean by default to solve it and then remove that option once this makes it into stable

[xd009642]

So 0.18.0-alpha2 is now released that fixes the issue until that rust PR makes it into the 1.53.0 stable, checked it and it works as expected 👍

Txs for adding --skip-clean!
