golangci-lint v1.24.0 still appears to not be cleaning up lock file

[SteelPhase]

Lock file should be cleaned up when running golangci-lint --version or golangci-lint --help

Hi,
thank you,
can't reproduce. Please, re-run golangci-lint with environment variable GL_DEBUG=exec

Just tested on linux, and got the below output. looks like golangci-lint version is fine, but gloangci-lint --version is not

I would say this is the issue for --version os.Exit(0) never lets you close your file lock

As another note version, and --version have two different execution paths. That os.Exit(0) stops --version from closing the lock. help, and --help also have two separate paths and have a similar issue.

golangci-lint/pkg/commands/root.go

Lines 19 to 22 in 6bd10d0

	if e.cfg.Run.PrintVersion {
	fmt.Fprintf(logutils.StdOut, "golangci-lint has version %s built from %s on %s\n", e.version, e.commit, e.date)
	os.Exit(0)
	}

I confirmed that it can be reproduced on v1.26.0, but not on v1.27.0.
It seems it's already fixed by #1070, which is included in the latest released version: v1.27.0.
So maybe you can resolve this by updating to v1.27.0.

As @SteelPhase pointed out, there were some paths that exits without removing lock file. Removing lock file is executed by cobra.Command's PostRun hook, but it is not set for those cases.
After #1070, it seems those paths don't exist because it is changed to acquiring file lock on PreRun and releasing it on PostRun.

closing due to the issue is fixed in the v1.27.0 release
