Package: dh-golang Version: 1.18 Severity: wishlist Tags: patch Currently build is always parallel even in compat <= 9 mode because dh-golang ignores "--parallel" and "--max-parallel" options.
Lack of support for parallel options is a practical problem because by default "go build" aggressively uses all CPU cores which can overuse resources on heavy packages. For example Kubernetes FTBFS on workstation with 8 cores and 32+ GiB of RAM due to lack of memory or (when there is enough RAM) it causes so much swapping during build that the whole system becomes nearly unusable. With Kubernetes and other packages it would be quite useful to be able to limit build to certain number of cores by using debhelper's "--max-parallel=N" option. The following patch does that: ~~~~ --- lib/Debian/Debhelper/Buildsystem/golang.pm +++ lib/Debian/Debhelper/Buildsystem/golang.pm @@ -178,8 +178,9 @@ $this->_set_gopath(); if (exists($ENV{DH_GOLANG_GO_GENERATE}) && $ENV{DH_GOLANG_GO_GENERATE} == 1) { $this->doit_in_builddir("go", "generate", "-v", @_, get_targets()); } + unshift @_, ('-p',$this->get_parallel()); $this->doit_in_builddir("go", "install", "-v", @_, get_targets()); } ~~~~ as well as it makes build respect "--parallel" option for DH consistency. -- Best wishes, Dmitry Smirnov GPG key : 4096R/53968D1B --- What can be asserted without proof can be dismissed without proof. -- Christopher Hitchens, 2004
