Github action gateway timeout #136

Open csiefer2 opened 1 week ago

csiefer2 commented 1 week ago

What was wrong?

I'm using coveralls through a github action. There are probably about ~50k gcov files that our testing generates.

We get finish the file processing and then this happens:

🚀 Posting coverage data to https://coveralls.io/api/v1/jobs
HTTP error:

Error: Gateway Time-out (504)
Message: <!DOCTYPE html>

Logs

Coveralls version: v0.6.12

Hi @csiefer2. Yes, this can happen with large C/C++ projects. coverage-reporter, which underlies our github-action, can process however many coverage report files you have in your environment, but above a certain number will lead to a timeout.

Our recommendation here is to use gcov to generate a single lcov report for your project (or at least fewer reports).

You can find steps to do so in these blog posts / tutorials:

By default, your lcov file will be exported as coverage.info, so if you think you'll have any extraneous or duplicate files in your environment, we additionally recommend that you specify at least the format, and ideally, the file as well.

format and file can be passed as a flag, and an argument, respectively, in the command line command for coverage-reporter, like this:

coveralls report coverage/coverage.info --format=lcov

For the github-action, you'll want to add those two input options, under with:, like this:

    - name: Coveralls Coverage Report Upload
      uses: coverallsapp/github-action@v2
      with:
        format: lcov
        file: path/to/coverage.info
