From cc564f929a4e32a829d35272533242b94797aa22 Mon Sep 17 00:00:00 2001 From: Patrick Ohly Date: Wed, 6 Mar 2019 17:23:07 +0100 Subject: [PATCH 01/69] verify-subtree.sh: relax check and ignore old content If for whatever reasons a repo already had a `release-tools` directory before doing a clean import of it with `git subtree`, the check used to fail because it found those old commits. This can be fixed by telling `git log` to stop when the directory disappears from the repo. There has to be a commit with removes the old content, because otherwise `git subtree add` doesn't work.

In the past, formatting of source differed depending on the version. Right now it is the content of the vendor directory which changes when switch back and forth between 1.12 and 1.13. We don't want to impose a certain workflow on developers, like forcing all invocations of Go to run inside a container. If developers want that, they can set up their development environment accordingly. But we should warn about this aspect to raise awareness. "make" invocations which involve Go now compare against the projects Go version (specified in travis.yml) once at the beginning. This is only a warning because we don't know which future version will be compatible with the project. Vendor directory handling gets updated, too: verification is now a separate script (became too complex for make) and there is a corresponding "update-vendor.sh". In contrast to verification, updating vendor is not integrated into make and thus itself invokes the go version check. --- build.make | 50 ++++++++---------------------------- update-vendor.sh | 23 +++++++++++++++++ verify-go-version.sh | 51 +++++++++++++++++++++++++++++++++++++ verify-vendor.sh | 60 ++++++++++++++++++++++++++++++++++++++++++++ 4 files changed, 145 insertions(+), 39 deletions(-) create mode 100755 update-vendor.sh create mode 100755 verify-go-version.sh create mode 100755 verify-vendor.sh diff --git a/build.make b/build.make index cbf6d455..6b89f5b2 100644 --- a/build.make +++ b/build.make @@ -62,7 +62,7 @@ ARCH := $(if $(GOARCH),$(GOARCH),$(shell go env GOARCH)) # Specific packages can be excluded from each of the tests below by setting the *_FILTER_CMD variables # to something like "| grep -v 'github.com/kubernetes-csi/project/pkg/foobar'".
