[pkg-go] automatic rebuild of binaries

[Ximin Luo]

When shared libraries are updated, binaries that use this library are also automatically updated. That is one of the main advantages of dynamic linking, and the excellent dependency-handling of APT allows us to do this without much headache, unlike e.g. on Windows.

Go does not currently have shared libraries, so a golang binary that is compiled in Debian, is *not* automatically updated when its library dependencies are updated (since currently[1] we only package libraries as source code).

This is counter-intuitive, and IMO a problem. Do people agree, and if so, how shall we try to solve it? One option is to set up other infrastructure to poke the maintainer of a binary to do a re-build when the shared libraries update. This is likely to happen quite often though, and creates a lot of manual work that is fundamentally unnecessary. Does Debian support anything like automatic rebuilding?
