Hi, gcov.php.net used to provide valgrind reports and code coverage for php-src. It no longer works with 7.4/8.0, because the OS is very old, and building new versions of PHP there gets very hard. The valgrind reports have essentially been subsumed by asan/ubsan on Azure Pipelines, but we're still missing a replacement for code coverage.
I think it should be possible to set up an Azure Pipelines job that runs tests with coverage and publishes it, preferably on Azure Pipelines itself, or if that doesn't work something like codecov.io. Maybe someone is interested in giving this a try? Regards, Nikita
