Stabilization Tracking: Golang

[tdyas]

This is a stabilization tracking ticket for the Go backend. Items here are intended to be resolved in order to remove the "experimental" label from Go support:

For stabilization

Build:

• go: support recompiling the standard library #17839
• Go backend tolerates missing go.sum entries #17794
• go: support vendored third-party dependencies #12768
• link .syso files into package archive #16827
• go: assembly may require generation of go_asm.h file #12943
• go: copy header files named for current GOOS/GOARCH to standard names #17478
• go: fix cgo bugs preventing kafka module from working with cgo #17592
• go: support non-local environments for go_binary #18115
• Build options:
  • cgo: add cgo_enabled field to go_binary to control cgo support #16833
  • go: support passing arbitrary compiler flags #17439
  • go: support passing arbitrary linker flags #17440
  • go: support passing arbitrary assembler flags #17441
  • go: support enabling data race detector #17437
  • go: support memory santiizer compilation mode #16838
  • go: support address sanitizer compilation mode #16837

Test:

• go: support capturing test profile outputs #16610
• Support -coverpkg for tests in go #17260
• Go: add [go-test].timeout_default #13782
• go: use target spec in output path for coverage #17446
• go: support non-local environments for testing go_package targets #18116

Not for stabilization

• go: build tests with fuzz tests using necessary compiler options #16609
• Go: hook up to test --debug #13411
• Wire up --debug-adapter for Go #16217
• Go: automate testdata folder via tailor and maybe dependency inference #13784
• cgo: provide options to configure compiler flag security regexs #16842
• go: support enabling additional build tags #17438
• go: supporting building Go plugins #17443
• go: supporting build C archives from Go binaries  #17444
• go: support building Go shared libraries  #17445
• go: support building position-independent executables ("pie") #17442

The docs page has this specific warning:

"""
go.mod and go.sum need to be up-to-date

Pants does not yet update your go.mod and go.sum for you; it only reads these files when downloading modules. Run go mod download all to make sure these files are correct.
"""

I don't have a lot of experience with golang, but I didn't see a ticket that clearly mapped to.

We should consider then what work we want to do for a "Pants-native" go.mod / go.sum experience. Also, the more general question I have been thinking about is whether go.work support should be part of the stabilization too.
