* Command-line input validation: reject unused argsEd Santiago2019-02-27
| | | | | | | | | | | | | | | Several podman commands accept no subcommands. Some of those were not actually checking, though, which could lead to user confusion. Added validation where missing; and, refactored to minimize duplication. (Side note: I decided against using cobra.NoArgs because its error message, "unknown command", misleadingly implies that there are known ones). Also added validation to varlink Signed-off-by: Ed Santiago <santiago@redhat.com>
* Do not make renumber shut down the runtimeMatthew Heon2019-02-21
| | | | | | | | | | | | | | | The original intent behind the requirement was to ensure that, if two SHM lock structs were open at the same time, we should not make such a runtime available to the user, and should clean it up instead. It turns out that we don't even need to open a second SHM lock struct - if we get an error mapping the first one due to a lock count mismatch, we can just delete it, and it cleans itself up when it errors. So there's no reason not to return a valid runtime. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* Add podman system renumber commandMatthew Heon2019-02-21
This command allows for renumbering Podman locks after an upgrade to Podman with SHM locks from a 1.0 or earlier branch, or after the number of locks was changed. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
