This fix tries to address the issue raised in 25927 where the HTTP headers have been chaged when AUthZ plugin is in place. This issue is that in `FlushAll` (`pkg/authorization/response.go`), the headers have been written (with `WriteHeader`) before all the headers have bee copied. This fix fixes the issue by placing `WriteHeader` after. A test has been added to cover the changes.` This fix fixes 25927 Signed-off-by: Yong Tang <yong.tang.github@outlook.com> Upstream-commit: 9cb8fb6ea03fcd78010ce7dd33585d96cd73e38c Component: engine
pkg/ is a collection of utility packages used by the Docker project without being specific to its internals.
Utility packages are kept separate from the docker core codebase to keep it as small and concise as possible. If some utilities grow larger and their APIs stabilize, they may be moved to their own repository under the Docker organization, to facilitate re-use by other projects. However that is not the priority.
The directory pkg is named after the same directory in the camlistore project. Since Brad is a core
Go maintainer, we thought it made sense to copy his methods for organizing Go code :) Thanks Brad!
Because utility packages are small and neatly separated from the rest of the codebase, they are a good place to start for aspiring maintainers and contributors. Get in touch if you want to help maintain them!
