Codecov processing failure with no error message

A few weeks ago, codecov stopped working for my personal project located at GitHub - grumpycoders/pcsx-redux: Latest iteration on the PCSX emulator, heavily focused on develo in a weird way, with little to no change in the repository itself.

The code coverage job configuration can be seen here:

What happens is the circleci job completes successfully, and successfully sends the coverage report to codecov with no problem whatsoever:

The “Upload Code Coverage” section says the following at the end:

  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100 3838k    0     0  100 3838k      0  9547k --:--:-- --:--:-- --:--:-- 9547k
    -> Reports have been successfully queued for processing at
CircleCI received exit code 0

But on the codecov website, I see this:

“There was an error processing coverage reports.” and no error message whatsoever to indicate what went wrong exactly, which isn’t helpful in troubleshooting what’s going on.

Anyone has an idea on where to begin troubleshooting what’s going on?

@nicolasnoble can you check that the file you are uploading has coverage information? You can do do cat ./coverage.txt (based off of this CI run)

Yes, the file exists, and seems proper. Here you have a copy of it, that I grabbed using circleci’s ssh shell debugging:

The job I just ran to get this file using circleci is at and the job says it uploaded successfully at Code coverage done right. which still contains the same blank error.

My reply seems stuck in spam limbo, probably because I’ve posted the several megabytes coverage.txt file I’ve extracted from the job.

@nicolasnoble fair enough. I’m not too familiar with lcov, but I’m guessing it has to do with the file format that we are receiving. I’ll see if I can get some help from our product team here.

I mean it used to work before, and it stopped working all of a sudden with no reason nor warning.

Alright well, after changing the exporter to lcov, this is now working again:

I guess the previous format (that seems to be the documented method still?) isn’t working properly anymore, which may still be something relevant for people to know.
