If you do not understand when the issue is or 27have other problems to fix the complaint, just ask and other project members 28can likely help out. 29 30Consider the following table while looking at pull request failures: 31 32 | CI platform as shown in PR | State | What to look at next | 33 | ----------------------------------- | ------ | -------------------------- | 34 | CI / fuzzing | stable | fuzzing results | 35 | CI / macos ... | stable | all errors and failures | 36 | FreeBSD FreeBSD: ... | stable | all errors and failures | 37 | LGTM analysis: Python | stable | new findings | 38 | LGTM analysis: C/C++ | stable | new findings | 39 | buildbot/curl_winssl_ ... | stable | all errors and failures | 40 | AppVeyor | flaky | all errors and failures | 41 | curl.curl (linux ...) | stable | all errors and failures | 42 | curl.curl (windows ...) | flaky | repetitive errors/failures | 43 44Sometimes the tests fail due to a dependency service temporarily being offline 45or otherwise unavailable, for example package downloads. In this case you can 46just try to update your pull requests to rerun the tests later as described 47below. 48 49## CI servers 50 51Here are the different CI environments that are currently in use, and how they 52are configured: 53 54### GitHub Actions 55 56GitHub Actions runs the following tests: 57 58- macOS tests with a variety of different compilation options 59- Fuzz tests ([see the curl-fuzzer repo for more 60 info](https://github.com/curl/curl-fuzzer)). 61- curl compiled using the Rust TLS backend with Hyper 62 63These are each configured in different files in `.github/workflows`. 64 65### Azure 66 67Not used anymore. 68 69### AppVeyor 70 71AppVeyor runs a variety of different Windows builds, with different compilation 72options. 73 74As of November 2021 `@bagder`, `@mback2k`, `@jay`, `@vszakats`, `@dfandrich` 75and `@danielgustafsson` have administrator access to the AppVeyor CI 76environment. Additional admins/group members can be added on request. 77 78The tests are configured in `appveyor.yml`. 79 80### Zuul 81 82Not used anymore. 83 84### Circle CI 85 86Circle CI runs a basic Linux test suite on Ubuntu for both x86 and ARM 87processors. This is configured in `.circleci/config.yml`. 88 89You can [view the full list of CI jobs on Circle CI's 90website](https://app.circleci.com/pipelines/github/curl/curl). 91 92`@bagder` has access to edit the "Project Settings" on that page. Additional 93admins/group members can be added on request. 94 95### Cirrus CI 96 97Not used anymore. 98
