Expected behavior
Successful build

When trying to build

> git clone git@github.com:RedisLabsModules/redismodule-rs.git
> cd redismodule-rs
> cargo tarpaulin

Got the following error:

0 ERROR cargo_tarpaulin: Failed to compile tests! Error: bitvec: cannot find attribute `skip` in this scope
Error: "Failed to compile tests! Error: bitvec: cannot find attribute `skip` in this scope"

So for RedisJSON, I got the SIGILL instruction, so I checked the readme and did cargo tarpaulin --features test and it works. Maybe you're missing the feature?

Well when I cloned redismodule-rs fresh it's using nom 7 and bitvec isn't in the dependency tree, I'd recommend upgrading whatever package is bringing it in cargo tree -i bitvec, but I can't see what is doing it... In the meantime --avoid-cfg-tarpaulin is a flag to go back to the legacy tarpaulin attribute behaviour.

I then ran tarpaulin using cargo tarpaulin --features test,experimental-api as this matched the features tested under in CI, and it compiled and was running fine until this error which I imagine is just due to my system setup - I'm not sure if I have redis installed on this machine:

running 2 tests
test test_keys_pos ... FAILED
test test_hello ... FAILED

failures:

---- test_keys_pos stdout ----
Error: failed to start redis server

Is there any more information that could help me recreate this? Compiler versions, any configuration etc? From what I see currently it all seems to work as expected

I just ran it with cargo tarpaulin --features test and got the same error:

Running on:

• Ubuntu 21.10
• rustup 1.24.3 (ce5817a94 2021-05-31)
• rustc 1.57.0 (f1edd0429 2021-11-29)

Strange, I just tried it with tarpaulin 0.18.5, with rustc 1.57.0 on ubuntu 18.04 and it worked fine. Can you do a cargo clean before you run tarpaulin?

[gkorland]

cargo clean didn't help

Haven't been able to reproduce, still works fine my end and now there's --engine llvm which further increases compat with other projects. So closing this as likely fixed.
