From f9c1b86feb36b530f7eab78e18e9a49decc87861 Mon Sep 17 00:00:00 2001 From: Sebastiaan van Stijn Date: Fri, 23 Apr 2021 18:34:53 +0200 Subject: [PATCH 1/2] go.mod: add replace rule to prevent unwanted updateds of grpc and jwt-go This replace rule is to prevent unwanted updates of grpc and jwt-go. When updating spf13/cobra, we noticed that google.golang.org/grpc got updated. Doing a search to find which modules (note here that `go mod graph` only looks at dependencies from a `go modules` perspective, and not all the (current version) of our dependencies use go modules). And I found that the only _modules_ depending on it are `github.com/spf13/viper` and `github.com/grpc-ecosystem/grpc-gateway`: ```bash $ go mod graph | grep ' google.golang.org/grpc' github.com/spf13/viper@v1.4.0 google.golang.org/grpc@v1.21.0 github.com/grpc-ecosystem/grpc-gateway@v1.9.0 google.golang.org/grpc@v1.19.0 ``` Of those, `github.com/grpc-ecosystem/grpc-gateway` is a dependency of `github.com/spf13/viper`: ```bash $ go mod graph | grep ' github.com/grpc-ecosystem/grpc-gateway' github.com/spf13/viper@v1.4.0 github.com/grpc-ecosystem/grpc-gateway@v1.9.0 ``` So looking at that one, it's a dependency of cobra: ```bash $ go mod graph | grep ' github.com/spf13/viper@v1.4.0' github.com/spf13/cobra@v1.0.0 github.com/spf13/viper@v1.4.0 ``` Ironically, while both `github.com/spf13/viper` and `github.com/grpc-ecosystem/grpc-gateway`, depend on `google.golang.org/grpc` and (through their `go.mod`) are responsible for `go mod` to update the dependency version of grpc, none of them are used: ```bash cat vendor/modules.txt | grep github.com/spf13/viper cat vendor/modules.txt | grep github.com/grpc-ecosystem/grpc-gateway ``` Unfortunately, `go modules` looks at `go.mod` to determine the *minimum version* required; _even if the parts of the modules specifying it in the `go.mod` are unused_. This patch adds a `replace` rule in go.mod to prevent updating grpc based on other dependencies that _declare_ `google.golang.org/grpc` as a dependency, but are not used and, hence, should not influence the minumum version.

Custom completions of nouns written in Go + +In a similar fashion as for static completions, you can use the `ValidArgsFunction` field to provide a Go function that Cobra will execute when it needs the list of completion choices for the nouns of a command. Note that either `ValidArgs` or `ValidArgsFunction` can be used for a single cobra command, but not both. +Simplified code from `helm status` looks like: + +```go +cmd := &cobra.Command{ + Use: "status RELEASE_NAME", + Short: "Display the status of the named release", + Long: status_long, + RunE: func(cmd *cobra.Command, args []string) { + RunGet(args[0]) + }, + ValidArgsFunction: func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) { + if len(args) != 0 { + return nil, cobra.ShellCompDirectiveNoFileComp + } + return getReleasesFromCluster(toComplete), cobra.ShellCompDirectiveNoFileComp + }, +} +``` +Where `getReleasesFromCluster()` is a Go function that obtains the list of current Helm releases running on the Kubernetes cluster. +Notice we put the `ValidArgsFunction` on the `status` subcommand. Let's assume the Helm releases on the cluster are: `harbor`, `notary`, `rook` and `thanos` then this dynamic completion will give results like + +```bash +# helm status [tab][tab] +harbor notary rook thanos +``` +You may have noticed the use of `cobra.ShellCompDirective`. These directives are bit fields allowing to control some shell completion behaviors for your particular completion. You can combine them with the bit-or operator such as `cobra.ShellCompDirectiveNoSpace | cobra.ShellCompDirectiveNoFileComp` +```go +// Indicates an error occurred and completions should be ignored. +ShellCompDirectiveError +// Indicates that the shell should not add a space after the completion, +// even if there is a single completion provided. +ShellCompDirectiveNoSpace +// Indicates that the shell should not provide file completion even when +// no completion is provided. +// This currently does not work for zsh or bash < 4 +ShellCompDirectiveNoFileComp +// Indicates that the shell will perform its default behavior after completions +// have been provided (this implies !ShellCompDirectiveNoSpace && !ShellCompDirectiveNoFileComp). +ShellCompDirectiveDefault +``` + +When using the `ValidArgsFunction`, Cobra will call your registered function after having parsed all flags and arguments provided in the command-line. You therefore don't need to do this parsing yourself. For example, when a user calls `helm status --namespace my-rook-ns [tab][tab]`, Cobra will call your registered `ValidArgsFunction` after having parsed the `--namespace` flag, as it would have done when calling the `RunE` function. + +##### Debugging + +Cobra achieves dynamic completions written in Go through the use of a hidden command called by the completion script. To debug your Go completion code, you can call this hidden command directly: +```bash +# helm __complete status har +harbor +:4 +Completion ended with directive: ShellCompDirectiveNoFileComp # This is on stderr +``` +***Important:*** If the noun to complete is empty, you must pass an empty parameter to the `__complete` command: +```bash +# helm __complete status "" +harbor +notary +rook +thanos +:4 +Completion ended with directive: ShellCompDirectiveNoFileComp # This is on stderr +``` +Calling the `__complete` command directly allows you to run the Go debugger to troubleshoot your code. You can also add printouts to your code; Cobra provides the following functions to use for printouts in Go completion code: +```go +// Prints to the completion script debug file (if BASH_COMP_DEBUG_FILE +// is set to a file path) and optionally prints to stderr. +cobra.CompDebug(msg string, printToStdErr bool) { +cobra.CompDebugln(msg string, printToStdErr bool) + +// Prints to the completion script debug file (if BASH_COMP_DEBUG_FILE +// is set to a file path) and to stderr. +cobra.CompError(msg string) +cobra.CompErrorln(msg string) +``` +***Important:*** You should **not** leave traces that print to stdout in your completion code as they will be interpreted as completion choices by the completion script.
