@ianlancetaylor requested issue #29986 to be considered for backport to the next 1.13 minor release.

@gopherbot Please open backport issues for 1.13 and 1.14

"go vet" should permit %O in fmt.Printf formats, as the formatting code was added in the 1.13 release.

Approving for 1.14 (#39288) and 1.13 (this issue). This is a serious problem affecting valid Go code with no workaround.

I've described the mechanics to perform this backport in full detail in #29986 (comment).

For the 1.13 backport, we need to:

  • first, reset the release-branch.go1.13 branch in x/tools to the correct revision, then
  • backport CL 202041 into release-branch.go1.13 in x/tools,
  • backport CL 203798 into release-branch.go1.13 in x/tools,
  • backport CL 235100 into release-branch.go1.13 in x/tools,
  • finally, re-vendor the latest x/tools release-branch.go1.13 branch in the cmd module.

%O is supported since Go 1.13. See golang.org/design/19308-number-literals for
the background.

Support for %O has been added by copying and adapting the %o implementation.

Updates golang/go#29986.
For golang/go#39287.

…0615191743-991d59a616de

This teaches vet to recognize the new formats %#b and %O on integers,
%x on float/complex. They have been supported since the 1.13 release,
but vet would warn about it.

Also update cmd/vet testdata accordingly, as was done in CL 202083.

Fixes #39287.
For #29986.
