bug(`forge coverage`): bug while generating lcov report

[IWildSniperI]

Component

Forge

Have you ensured that all of these are up to date?

• [X] Foundry
• [ ] Foundryup

What version of Foundry are you on?

0.2.0

What command(s) is the bug in?

forge coverage --report lcov

Operating System

Linux

Describe the bug

after i run forge coverage --report lcov

with consideration that forge works normally

[grandizzy]

please provide complete output of forge --version, would be great if you could also point to source code to replicate such. thank you

[DaniPopes]

could also be stale artifacts, can you try forge clean and trying again? Otherwise it could be solc mishandling UTF-8 characters

[IWildSniperI]

@grandizzy so sorry for late responses code with error https://github.com/Cyfrin/2024-07-biconomy.git

i got same error on another Codes too that i don't remember

[IWildSniperI]

@DaniPopes will try and update here

[grandizzy]

works OK here, @IWildSniperI as @DaniPopes says looks to be UTF-8 handling (maybe no locale installed on your OS?), what OS you use? (btw you have to yarn coverage:forge for that repo instead forge coverage --report lcov or add --ir-minimum to support require with custom error)

[IWildSniperI]

@grandizzy i have done what you said Sorry for the confusion for not having that note in the issue body

Not doing --ir-minimum would already have brought stack too deep error

So i preferred to put the main command that had that issue (cause some repos didn't require --ir-minimum) and the problem kept arriving

Iam using wsl on Windows

[IWildSniperI]

Only showed in the new version tho

1 or 2 months earlier i never got such a problem

Right now iam getting it often

[grandizzy]

what's the output for cat /etc/default/locale ?

@grandizzy

[grandizzy]

I think I have a theory but to confirm you would need to remove all these headers from sol files and retry :smile:

// ──────────────────────────────────────────────────────────────────────────────
//     _   __    _  __
//    / | / /__ | |/ /_  _______
//   /  |/ / _ \|   / / / / ___/
//  / /|  /  __/   / /_/ (__  )
// /_/ |_/\___/_/|_\__,_/____/
//
// ──────────────────────────────────────────────────────────────────────────────

[IWildSniperI]

@grandizzy 😕really?

Just want to confirm that same problem came for one without headers

See: https://github.com/Cyfrin/2024-07-templegold.git (protocols subfolder)

[grandizzy]

hey @IWildSniperI were you able to test it without those headers? thanks

[IWildSniperI]

@grandizzy

[grandizzy]

@IWildSniperI it still looks like there's the header, see the message above contains // ──────────────────────────────────────────────────────────────────────────────. Maybe try forge clean. What I want to see if WSL introduce bad chars like in https://github.com/microsoft/terminal/issues/386

[IWildSniperI]

did forge clean same problem

[grandizzy]

can you paste the output, is the header still printed / same error? either way I don't think there's much we can do here as it looks like wsl related issue...

[grandizzy]

also try updating foundryup there are some new things included and error line doesn't match anymore

[grandizzy]

@IWildSniperI going to close this for now, please apply suggested actions and report back if still an issue. thank you!
