It is used when running the Forgejo container like so: docker run --name forgejo -e FORGEJO__security__INSTALL_LOCK=true \ -d codeberg.org/forgejo/forgejo:1.18 Signed-off-by: Earl Warren (cherry picked from commit 6cd61e2ab701ae9236ff9a68520ee1e2d03e6193) (cherry picked from commit 62cae8cc6a6ddc9e5bb066c81834b75cef3be29f) (cherry picked from commit aee1afc5097531b2740b2aa8ef4aef745e7a1be0) (cherry picked from commit 6ba563cd9b09d012a804f3f438c5ae4e38ca6ced) (cherry picked from commit 6429b20f4a1561480a4a0c214cc571f79c313be0) (cherry picked from commit dd545aa077e21616b406d765b19a75df643a9695) (cherry picked from commit 63a00e573e2d6b6bfb75d28a816327435bace02d) (cherry picked from commit 8e35a50b91fcec0b27b6b5458facb12e9bda8505) (cherry picked from commit 26e8fb6cd953a6c9dfae89b430856895c7253a7c) (cherry picked from commit 56bbf644beb25f62964b2c0c847d7b9d711ed56e) --- .woodpecker/testing-amd64.yml | 8 ++++ .../environment-to-ini/environment-to-ini.go | 48 ++++++++++--------- .../environment-to-ini_test.go | 21 ++++++++ 3 files changed, 55 insertions(+), 22 deletions(-) create mode 100644 contrib/environment-to-ini/environment-to-ini_test.go diff --git a/.woodpecker/testing-amd64.yml b/.woodpecker/testing-amd64.yml index 340ee55736..94fd9e1844 100644 --- a/.woodpecker/testing-amd64.yml +++ b/.woodpecker/testing-amd64.yml @@ -75,6 +75,14 @@ pipeline: commands: - ./build/test-env-prepare.sh + environment-to-ini: + image: *golang_image + environment: + GOPROXY_OVERRIDE: *goproxy_override + commands: + - *goproxy_setup + - go test contrib/environment-to-ini/environment-to-ini.go contrib/environment-to-ini/environment-to-ini_test.go + build: image: *test_image environment: diff --git a/contrib/environment-to-ini/environment-to-ini.go b/contrib/environment-to-ini/environment-to-ini.go index b502c15cec..1b8b63faaa 100644 --- a/contrib/environment-to-ini/environment-to-ini.go +++ b/contrib/environment-to-ini/environment-to-ini.go @@ -1,3 +1,4 @@ +// Copyright 2023 The Forgejo Authors.
