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 d887235e081844e80c74979938c669fd68ed04a2) (cherry picked from commit c9a0a44e28237a0b1ff3c65abc5b078383cdf4ac) (cherry picked from commit 2cae2fca8e9889278aaf98a710cf062a596c9984) (cherry picked from commit c457919a2aa2af821741efc3298a9a1d8d05688e) --- .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 28be98c706..949b8781fe 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.
