Fedora 32 System-Wide Change proposal: Golang 1.14

[Ben Cotton]

https://fedoraproject.org/wiki/Changes/golang1.14

== Summary ==
Rebase of Golang package to upcoming version 1.14 in Fedora 32,
including rebuild of all dependent packages(pre-release version of Go
will be used for rebuild, if released version will not be available at
the time of the mass rebuild).

== Owner ==
* Name: [[User:Jcajka| Jakub Čajka]]
* Email: jcajka(a)redhat.com

== Detailed Description ==

Rebase of Golang package to upcoming version 1.14 in Fedora 32. Golang
1.14 is schedule to be released in Feb 2020.
Due to current nature and state of Go packages, rebuild of dependent
package will be required to pick up the changes.

== Benefit to Fedora ==

Staying closely behind upstream by providing latest release of golang,
which includes performance improvements and improvements in support
for currently supported platforms among other bug fixes and new
features. For complete list of changes see upstream change notes at
https://tip.golang.org/doc/go1.14 . In result Fedora will be providing
solid development platform for Go language.

== Scope ==
* Proposal owners: Rebase golang package in f32, help with resolving
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. Tracking ticket
https://pagure.io/releng/issue/9136
* Policies and guidelines: N/A
* Trademark approval: N/A

== Upgrade/compatibility impact ==
None

== How To Test ==
;0.
:a)Install golang 1.14 from rawhide and use it to build your
application(s)/package(s).
:b)Scratch build against rawhide.
;1.
:Your application/package built using golang 1.14 should work as expected.

== User Experience ==
None

== Dependencies ==
<pre>
dnf repoquery -q  --releasever=rawhide --disablerepo='*'
--qf='%{name}' --enablerepo=fedora-source --enablerepo=updates-source
--enablerepo=updates-testing-source --archlist=src --whatrequires
'golang'

--enablerepo=updates-testing-source --archlist=src --whatrequires
'go-rpm-macros'
</pre>
<pre>
Omitted due to the number of packages listed ~1100.
</pre>

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.

== Contingency Plan ==
* Contingency mechanism:Reverting to  golang version 1.13.X if
significatnt issues are discovered.
* Contingency deadline: Beta Freeze(?)
* Blocks release? No
* Blocks product? No

== Documentation ==
https://tip.golang.org/doc/go1.14

Do we really need to rebuild all thousand of packages given that most
of them are providing only noarch devel packages with sources? Don't
we need to rebuild only those which provide binaries?

I don't disagree, but if the rebuild will be facilitated as part of the regular
mass-rebuild it will be "free". Other technical challenge is to find packages
that truly need rebuild(use Go compiler during the build, for tests and/or building
binaries) as that information is no longer present in the SRPM metadata with the new Go
packaging scheme(although even source only packages should have their tests suites run,
ideally, thus needing the compiler), compiler is always pulled in to the build root via
the new macros package.

We need rebuild to re-run the tests to see if the new Golang has broken some 
packages.
