From 2501f6ef0f90edcaee4643247305e7ed2014eb79 Mon Sep 17 00:00:00 2001 From: Sebastiaan van Stijn Date: Sat, 12 Oct 2024 14:42:56 +0200 Subject: [PATCH] csi: remove unused startMockServer and github.com/rexray/gocsi dependency This utility was used in manager/volumes/volumes_test.go, which got deleted in b0a1aa66decad17f9be00ecdfcff2f457ddcf10f, making the startMockServer unused. Remove the file, so that we can remove the problematic github.com/rexray/gocsi dependency, which is unmaintained, and required us to use Drew's fork to prevent legacy dependencies from being pulled in through the indirect github.com/coreos/etcd/clientv3 dependency; go: finding module for package github.com/coreos/etcd/clientv3/concurrency go: finding module for package github.com/coreos/etcd/clientv3 go: found github.com/coreos/etcd/clientv3 in github.com/coreos/etcd v3.3.27+incompatible go: found github.com/coreos/etcd/clientv3/concurrency in github.com/coreos/etcd

It is not a - deal-breaker otherwise, but please be prepared to add a comment or - explanation as to why you feel multiple commits are required. - -People contributing code to this project must adhere to the following rules. -These standards are in place to keep code clean, consistent, and stable. - -## Documentation -There are two types of documentation: source and markdown. - -### Source Code -All source code should be documented in accordance with the -[Go's documentation rules](http://blog.golang.org/godoc-documenting-go-code). - -### Markdown -When creating or modifying the project's `README.md` file or any other -Markdown documentation, please keep the following rules in mind: - -1. All markdown should be limited to a width of 80 characters. This makes -the document easier to read in text editors. GitHub still produces the -proper result when parsing the markdown. -2. All links to internal resources should be relative. -3. All links to markdown files should include the file extension. - -## Style & Syntax -All source files should be processed by the following tools prior to being -committed. Any errors or warnings produced by the tools should be corrected -before the source is committed. - -Tool | Description ------|------------ -[gofmt](https://golang.org/cmd/gofmt/) | A golang source formatting tool -[golint](https://github.com/golang/lint) | A golang linter -[govet](https://golang.org/cmd/vet/) | A golang source optimization tool -[gocyclo](https://github.com/fzipp/gocyclo) | A golang cyclomatic complexity detection tool. No function should have a score above 0.15 - -The [go-plus](https://atom.io/packages/go-plus) plug-in is available for -the [Atom](https://atom.io/) IDE and will handle all of the above tooling -automatically. - -Another option is to use a client-side, pre-commit hook to ensure that the -sources meet the required standards. For example, in the project's `.git/hooks` -directory create a file called `pre-commit` and mark it as executable. Then -paste the following content inside the file: - -```shell -#!/bin/sh -gofmt -w $(find . -name "*.go" | grep -v ./vendor) -``` - -The above script will execute prior to a Git commit operation, prior to even -the commit message dialog. The script will invoke `gofmt` for all of the -project's Go source files. If the command returns a non-zero exit code, -the commit operation will abort with the error. - -## Commit Messages -Commit messages should follow the guide [5 Useful Tips For a Better Commit -Message](https://robots.thoughtbot.com/5-useful-tips-for-a-better-commit-message). -The two primary rules to which to adhere are: - - 1. Commit message subjects should not exceed 50 characters in total and - should be followed by a blank line. - - 2.
