Detailed Description

Rebase of Golang package to upcoming version 1.18 in Fedora 36. Golang 1.18 is scheduled to be released in February 2022. Due to Go packages' current nature and state, the rebuild of dependent packages will be required.

Benefit to Fedora

Stay closely behind upstream by providing the latest release of Go, which includes improved support of the risc-v processor architecture and added support for aarch64 based darwin(macOS) machines, among other bug fixes, enhancements and new features. For a complete list of changes, see upstream change notes at https://tip.golang.org/doc/go1.18 . Therefore Fedora will be providing a reliable development platform for Go language and projects written in it.

Scope

• Proposal owners: Rebase Golang package in Fedora 36, help resolve possible issues found during package rebuilds.

• Other developers: Fix possible issues, with help from Golang maintainers.

• Release engineering: Rebuild of dependent packages as part of planned mass-rebuild.

• Policies and guidelines: N/A

• Trademark approval: N/A

Omitted due to the number of packages listed ~1600.

Not all of listed require re-build as they might not ship binaries and/or do not use golang compiler during build, but only use Go rpm macros that pull it in to every build root.
