Package: dh-golang Version: 1.17 Severity: normal --buildsystem=golang does a nice job preparing build directory in `dh_auto_configure` by symlinking source packages from under "/usr/share/gocode/src" to directory specified with "--builddirectory" argument.
However it works incorrectly when $(DH_GOPKG) package (i.e. current package to build) is pre-installed because in such case installed and new version of the package are merged in build directory. Suppose you are building a "golang-github-foo-bar" package which no longer provides "github.com/foo/bar/obsolete-feature". If previous version of the package is installed then dh_golang incorrectly symlink "/usr/share/gocode/src/github.com/foo/bar/obsolete-feature" into build directory. This problem should be easy to detect and avoid as dh_golang already knows which package not to link from $(DH_GOPKG) or XS-Go-Import-Path header. I suppose we just need to ignore/skip pre-installed package which is build. Also it would be nice to produce a warning to notify maintainer about potential problem. Arguably circular dependencies are not in scope of what dh_golang should be doing but there are cases when package can be re-built (staged) on maintainer's machine in presence of previous version of the same package. Correct handling of such situations would be useful. Thanks. -- Regards, Dmitry Smirnov GPG key : 4096R/53968D1B --- Truth — Something somehow discreditable to someone. -- H. L. Mencken, 1949
