From e81d76ffe1f8e698e863f9a5b5aad2804a309d75 Mon Sep 17 00:00:00 2001 From: Sebastiaan van Stijn Date: Mon, 3 Feb 2025 19:03:33 +0100 Subject: [PATCH] cli/command/container: minor cleanups - use apiClient instead of client for the API client to prevent shadowing imports. - use dockerCLI with Go's standard camelCase casing. - suppress some errors to make my IDE and linters happier Signed-off-by: Sebastiaan van Stijn --- cli/command/container/cp.go | 31 ++++++++++++++++--------------- cli/command/container/exec.go | 12 ++++++------ cli/command/container/inspect.go | 12 +++++------- 3 files changed, 27 insertions(+), 28 deletions(-) diff --git a/cli/command/container/cp.go b/cli/command/container/cp.go index 3e975a81b6..5eb3d7113c 100644 --- a/cli/command/container/cp.go +++ b/cli/command/container/cp.go @@ -208,7 +208,7 @@ func resolveLocalPath(localPath string) (absPath string, err error) { return archive.PreserveTrailingDotOrSeparator(absPath, localPath), nil } -func copyFromContainer(ctx context.Context, dockerCli command.Cli, copyConfig cpConfig) (err error) { +func copyFromContainer(ctx context.Context, dockerCLI command.Cli, copyConfig cpConfig) (err error) { dstPath := copyConfig.destPath srcPath := copyConfig.sourcePath @@ -224,11 +224,11 @@ func copyFromContainer(ctx context.Context, dockerCli command.Cli, copyConfig cp return err } - client := dockerCli.Client() + apiClient := dockerCLI.Client() // if client requests to follow symbol link, then must decide target file to be copied var rebaseName string if copyConfig.followLink { - srcStat, err := client.ContainerStatPath(ctx, copyConfig.container, srcPath) + srcStat, err := apiClient.ContainerStatPath(ctx, copyConfig.container, srcPath) // If the destination is a symbolic link, we should follow it. if err == nil && srcStat.Mode&os.ModeSymlink != 0 { @@ -247,14 +247,14 @@ func copyFromContainer(ctx context.Context, dockerCli command.Cli, copyConfig cp ctx, cancel := signal.NotifyContext(ctx, os.Interrupt) defer cancel() - content, stat, err := client.CopyFromContainer(ctx, copyConfig.container, srcPath) + content, stat, err := apiClient.CopyFromContainer(ctx, copyConfig.container, srcPath) if err != nil { return err } defer content.Close() if dstPath == "-" { - _, err = io.Copy(dockerCli.Out(), content) + _, err = io.Copy(dockerCLI.Out(), content) return err } @@ -283,12 +283,12 @@ func copyFromContainer(ctx context.Context, dockerCli command.Cli, copyConfig cp return archive.CopyTo(preArchive, srcInfo, dstPath) } - restore, done := copyProgress(ctx, dockerCli.Err(), copyFromContainerHeader, &copiedSize) + restore, done := copyProgress(ctx, dockerCLI.Err(), copyFromContainerHeader, &copiedSize) res := archive.CopyTo(preArchive, srcInfo, dstPath) cancel() <-done restore() - fmt.Fprintln(dockerCli.Err(), "Successfully copied", progressHumanSize(copiedSize), "to", dstPath) + _, _ = fmt.Fprintln(dockerCLI.Err(), "Successfully copied", progressHumanSize(copiedSize), "to", dstPath) return res } @@ -297,7 +297,7 @@ func copyFromContainer(ctx context.Context, dockerCli command.Cli, copyConfig cp // about both the source and destination.
