Tarpaulin 0.18.0-alpha1 fails after a `cargo build`

winksaville commented 3 years ago

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 commented 3 years ago

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 https://github.com/rust-lang/rust/issues/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 commented 3 years ago

@xd009642, txs for looking into this.

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

winksaville commented 3 years ago

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!

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

xd009642 commented 3 years ago

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 :+1:

Txs for adding --skip-clean!

Tarpaulin 0.18.0-alpha1 fails after a `cargo build` #736
