Once you feel your packages are ready for review (possibly this reply
prompts some changes?), please send an up-to-date list of git URLs to what
you’d like reviewed. Thanks!

Correct, and up to you (see the caveat which tincho expressed). Bug #812721
discusses a gbp import-ref command which would honor Files-Excluded, but
we’re not quite there yet. So, if you want to stick to orig tarballs for
the time being, Files-Excluded will work.

nit: use find’s -delete action?

DH_GOLANG_EXCLUDES, like the other directives, operates on Go packages, not
individual source code files. All files within github.com/containerd/cgroups
belong to the cgroups package, so you can only exclude it in its entirety,
which is not desired in this case.

Yes, if the whole file should be ignored. In case only individual tests are
affected, prefer using t.Skipf please:

Ah, I see what’s wrong here: you are supposed to run lintian on a .changes
file, so that it can inspect both the binary packages (*.deb) and the
source package (*.dsc). Indeed, when building gogoprotobuf and running
“lintian golang-gogoprotobuf_0.5-1_amd64.changes”, I don’t get any warnings
about statically linked binaries.

I don’t see a connection between the two fields. lintian examines the
Build-Depends field for detecting Go packages. Specifically, a package is a
Go package if golang-go or golang-any are present in Build-Depends.

Aside from that, yes, Built-Using must be set when building Go binary
packages, and must be unset for Go library packages. I have recently added
lintian warnings which cover these cases, but they’re not yet in a released
lintian version.

Please feel free to send a PR! :)
