x/build/internal/releasetargets: evaluate for each upcoming major Go release #40561

dmitshur · 2020-08-04T03:36:08Z

At the start of each code freeze, we should evaluate the choice of releaselets (builders that are used for constructing a release artifact) used to make the upcoming major Go release, and confirm they are the most appropriate choice out of what is available.

The start of a code freeze is a safe time to introduce a builder change, as it will be tested during pre-release versions, starting with beta 1 and onwards.

Making this a release blocker for Go 1.16 (and not okay after beta 1—it needs to be done before). Once completed, this issue should be moved to the next major release milestone.

Edit: Starting with Go 1.21, releaselets are only used for running tests. Release artifact construction happens by reproducibly cross-compiling a distpack distribution on a fixed builder.

The @golang/release team has considered the current builders, and we are proposing the following builder changes for the Go 1.16 release:

go1.16*.linux-amd64.tar.gz

	Builder Name	Host Type
Current	linux-amd64-jessie	host-linux-jessie
New	linux-amd64	host-linux-stretch

(Or rather a new builder, identical to the linux-amd64 one, just named linux-amd64-stretch instead.)

Rationale: Debian 8 "Jessie" Long Term Support (LTS) has ended on June 30, 2020 (see https://wiki.debian.org/LTS). We want to start using the next stable release, Debian 9 "Stretch", which has LTS support until June 2022.

Note that this has caused #31293 in April 2019 when this change was made unintentionally as part of a minor release, and it was reverted. We hope that it should be okay to try again for Go 1.16 a year later, since this is being done intentionally this time, and for a major release. CC @ianlancetaylor, @jayconrod, @bradfitz.

go1.16*.linux-386.tar.gz

	Builder Name	Host Type
Current	linux-386	host-linux-jessie
New	linux-386-stretch	host-linux-stretch

Rationale: Same as the one above for linux/amd64.

go1.16*.linux-armv6l.tar.gz

	Builder Name	Host Type
Current	linux-arm	host-linux-arm-scaleway
New	linux-arm-aws	host-linux-arm-aws

Rationale: The replacement builder has proven to be more reliable, and it is easier for us to maintain.

go1.16*.linux-arm64.tar.gz

	Builder Name	Host Type
Current	linux-arm64-packet	host-linux-arm64-packet
New	linux-arm64-aws	host-linux-arm64-aws

Rationale: The replacement builder has proven to be more reliable, and it is easier for us to maintain.

Also see #42304 (comment).

Feedback is welcome: we are happy to alter the plan based on information we haven't already considered. These builder changes are planned for Go 1.16 Beta 1, and we will re-evaluate this as needed based on any new findings and feedback.

See https://golang.org/issues/40561#issuecomment-731482962 for the plan description and rationale. Add new builder definitions that are needed for the plan. Don't rely on generic builder name like "linux-amd64" to avoid a repeat of golang.org/issue/31293; use a specific builder name instead. Remove support and test cases for Go 1.13, it's unsupported per release policy. For golang/go#40561.

CL 276034 has implemented the aforementioned plan for Go 1.16.

We'll need to revisit this issue next time during the Go 1.17 development cycle. (If we discover problems with the Go 1.16 plan, we'll come back here, or file new issues.) Moving to the next milestone for now.

While working on issue #39326, it has become clear to me that the C compile we have installed on our windows gomotes (at least the ones I have used) is pretty ancient -- GCC 5. It would be great if we could update the version to something a bit more recent (V10 maybe). Also worth noting that many folks are now using clang instead of gcc on windows -- it would be great if our gomotes had clang available as well.

@thanm Can you please file a separate issue to track that work, and CC @golang/release? It may need more information/investigation. Thanks.

Change https://golang.org/cl/278357 mentions this issue: cmd/release: update checkRelocations for Go 1.16

The plan in https://golang.org/issue/40561#issuecomment-731482962 involved updating the linux-amd64 target from Debian Jessie to Debian Stretch, which in turn comes with a newer version of GCC. checkRelocations was added in CL 171317 in response to a bad minor release that was accidentally issued without the intended fix, and needs to be updated for Go 1.16 and newer releases. It's not clear if we want to maintain it indefinitely for future Go versions, but keep it for a bit longer. Add a note to make it clear that it can be removed as needed in the future. For golang/go#40561. Updates golang/go#31293.

CL 547935 takes care of the port list for Go 1.22.

After Go 1.22.0 is out, all release artifacts we produce will be via reproducible cross-compilation and distpack, so the work of "evaluate the choice of releaselets (builders that are used for constructing a release artifact)" that this issue tracks becomes obsolete. We still need to handle the port list, though it'll be possible to replace its generation with a run-time computation if that's easier. And the releasetargets package can be simplified. We do still need to continuously maintain and update OS versions, but that's out of scope for here.

Dealing with all that is for after Go 1.22.0 is out, so moving this to the next milestone to revisit later.

The Target struct fields Builder, LongTestBuilder, and BuildOnly were applicable to releases prior to distpacks (i.e., Go 1.20 and older). By now, all releases are built on a secured Linux machine (and verified by rebuilding on another secured Windows machine), installers are built by the same pipeline that's responsible for performing signing, and the tests are run via the "advisory builder" loop. These fields have become meaningless and confusing, so drop them. Print whether a port is primary or not in releases.txt, so that if a map entry like "linux-amd64": &Target{} that only has implicit effects left by now is accidentally removed from allReleases, it'll be easy to spot the effect via the releases.txt diff. There's a bit more to do before the entire package becomes obsolete. For golang/go#40561.

Change https://go.dev/cl/585216 mentions this issue: internal/releasetargets: add openbsd/ppc64 target for Go 1.22 onwards

The release target list has two underlying sources: the allReleases map and the allPorts map. The former is a small curated map, mostly used to indicate which ports are first-class, and to set a few port properties. The latter is generated from 'go tool dist list' output for each major Go release. Unfortunately, the logic in TargetsForGo1Point ended up not taking into account that CL 547935 added allports/go1.22.txt with the openbsd/ppc64 port in it because the allReleases map didn't have an entry for go1.22. As a result, we haven't been making releases for the openbsd/ppc64 port as intended. :( Fix this by making sortedReleases consult both sources. For golang/go#40561. For golang/go#56001.
