Adopt new Go Packaging Guidelines
The current Go packaging guidelines have been in a draft state for several years now, and they do not reflect the current practices from the Go SIG. As a result of new RPM macros developed by Nicolas Mailhot, the Go SIG wishes to formally adopt new Go Packaging Guidelines, which aim at automation, reliability and simplicity.

Over 775 Go packages are currently residing in Fedora's repositories, yet no formal guidelines have ever been approved. As a result, the various Go SPECs are inconsistent and most often outdated. Moreover, the next version of Go, 1.13, will introduce the concept of modules by default, which will completely change how Go libraries are distributed. With the current state of our tooling, the Go SIG is not prepared to face such a drastic change.
Nicolas Mailhot has worked on a set of new RPM macros which will allow us to disconnect the upstream Go tooling from the downstream integration inside RPM. This will allow us to adapt easily to future upstream changes without the need to rewrite our SPEC catalogue.
Benefit to Fedora
- Simplicity: SPEC files are simpler, less error-prone
- Automation: the new macros computes packages definition, Requires, Provides and has provision for the new automated BuildRequires
- Standardization of SPEC files across the Go library
- Drastic reduction of boilerplate and SPEC size
- Automatic removal of vendored code
- Ease of testing: all units tests are detected and run
- Ease of upkeep
- Ease of adaptation to upstream changes
- Proposal owners:
- Get the last macros approved in redhat-rpm-config
- Get golist, the tool detecting dependencies, updated and split from the go-compilers package
- Release GOPATH directory ownership from the golang package, so it can be managed by the go-rpm-macros package
- Get go-rpm-macros packaged and reviewed
- Retire go-srpm-macros and go-compilers
- Port existing Go packages to the new macros (it probably won't be finished by Fedora 31)
- Other developers: N/A (not a System Wide Change)
- Release engineering: N/A
- List of deliverables: N/A (not a System Wide Change)
- Policies and guidelines: Get the Go packaging guidelines approved by the Packaging Committee
No compatibility impact is expected. All the new macros are backward compatible with the old ones.
How To Test
The COPR nim/macros-ng can be used to test the new macros on Rawhide. Sample SPEC files are available in the FPC Guidelines proposal.
The user impact is minimal or nil. As a result of the simplification of SPEC files, we may ship updated libraries more quickly, and it may be easier for new contributors to package Go applications.
N/A (not a System Wide Change)
- Contingency mechanism: If the required packages are not merged by the deadline target, or if the Guidelines are not approved, we may continue with our current set of non-approved practices. No other impact is expected.
- Contingency deadline: N/A (not a System Wide Change)
- Blocks release? No
- Blocks product? No
The FPC Guidelines proposal is available on eclipseo personal space.
