An update that has one recommended fix can now be installed.


This update for go1.14 fixes the following issues:

go1.14 (released 2020-02-25) is a major release of Go. (bsc#1164903)
go1.14.x minor releases will be provided through February 2021.
Most changes are in the implementation of the toolchain, runtime, and libraries. As always, the release maintains the Go 1 promise of compatibility. We expect almost all Go programs to continue to compile and run as before.

  • See release notes Excerpts relevant to OBS environment and for SUSE/openSUSE follow:
  • Module support in the go command is now ready for production use, and we encourage all users to migrate to Go modules for dependency management.
  • RISC-V experimental support for 64-bit RISC-V on Linux (GOOS=linux, GOARCH=riscv64). Be aware that performance, assembly syntax stability, and possibly correctness are a work in progress.
  • When the main module contains a top-level vendor directory and its go.mod file specifies go 1.14 or higher, the go command now defaults to -mod=vendor for operations that accept that flag. A new value for that flag, -mod=mod, causes the go command to instead load modules from the module cache (as when no vendor directory is present).
  • When -mod=vendor is set (explicitly or by default), the go command now verifies that the main module's vendor/modules.txt file is consistent with its go.mod file.
  • go list -m no longer silently omits transitive dependencies that do not provide packages in the vendor directory. It now fails explicitly if -mod=vendor is set and information is requested for a module not mentioned in vendor/modules.txt.
  • The go get command no longer accepts the -mod flag. Previously, the flag's setting either was ignored or caused the build to fail.
  • mod=readonly is now set by default when the go.mod file is read-only and no top-level vendor directory is present.
  • modcacherw is a new flag that instructs the go command to leave newly-created directories in the module cache at their default permissions rather than making them read-only. The use of this flag makes it more likely that tests or other tools will accidentally add files not included in the module's verified checksum. However, it allows the use of rm -rf (instead of go clean -modcache) to remove the module cache.
  • modfile=file is a new flag that instructs the go command to read (and possibly write) an alternate go.mod file instead of the one in the module root directory. A file named go.mod must still be present in order to determine the module root directory, but it is not accessed. When -modfile is specified, an alternate go.sum file is also used: its path is derived from the -modfile flag by trimming the .mod extension and appending .sum.
