* enable errcheck linterPaul Holzinger2022-04-29
| | | | | | | | The errcheck linter makes sure that errors are always check and not ignored by accident. It spotted a lot of unchecked errors, mostly in the tests but also some real problem in the code. Signed-off-by: Paul Holzinger <pholzing@redhat.com>
* shell completion --format: use structs by referencePaul Holzinger2022-04-28
| | | | | | | | | | | | For the AutocompleteFormat function we expect the correct template struct which is used in the golang template. The function can handle both struct and pointer to a struct. Using the reference is more efficient since it doe snot have to copy the whole struct. Also change some structs to use he actual type from the template instead of some nested one to make sure it has to correct fields. Signed-off-by: Paul Holzinger <pholzing@redhat.com>
* shell completion --format: work with nil structsPaul Holzinger2022-04-28
| | | | | | | | | | | | | AutocompleteFormat() takes the format struct as argument. Often the structs are deeply nested and contain other structs. Up until now if there was a pointer to a struct the logic was not able to get the field names from that, simply because the pointer was nil. However it is possible to create a new initialized type with reflect.New(). This allows us to complete all struct fields/functions even when there nil pointers. Therefore we can drop the extra initialization which was done by some callers. Signed-off-by: Paul Holzinger <pholzing@redhat.com>
* enable gocritic linterPaul Holzinger2022-04-26
| | | | | | | | | | | | | | | | | | | | | | The linter ensures a common code style. - use switch/case instead of else if - use if instead of switch/case for single case statement - add space between comment and text - detect the use of defer with os.Exit() - use short form var += "..." instead of var = var + "..." - detect problems with append() ``` newSlice := append(orgSlice, val) ``` This could lead to nasty bugs because the orgSlice will be changed in place if it has enough capacity too hold the new elements. Thus we newSlice might not be a copy. Of course most of the changes are just cosmetic and do not cause any logic errors but I think it is a good idea to enforce a common style. This should help maintainability. Signed-off-by: Paul Holzinger <pholzing@redhat.com>

* system service: remove unnecessary pointer to listnerPaul Holzinger2022-04-21

* Remove error stutterDaniel J Walsh2022-03-25
| | | | | | | | | | | | | | | | | When podman gets an error it prints out "Error: " before printing the error string. If the error message starts with error, we end up with Error: error ... This PR Removes all of these stutters. logrus.Error() also prints out that this is an error, so no need for the error stutter. [NO NEW TESTS NEEDED] Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>

* podman system df: fix percent calculationPaul Holzinger2022-03-21
| | | | | | | | | | | | | | | | The calculate the percentage we need floating point numbers. The current code however casted the result of reclaimable/size to an int first. Casting to an int in go will just discard the decimal points, thus the result was either 0 or 1 so if multiplied by 100 it would show up as 0% or 100%. To fix this we have to multiply by 100 first before casting the result to an int. Also add a check for div by zero which results in NaN and use math.Round() to correctly round a number.

* fix empty newline in version outputPaul Holzinger2022-03-15
| | | | | | | | | | | | | When podman is build without git commit information it will print a empty newline instead. This is undesirable and a regression introduced in commit 7d22cc88ef38.

* system prune: remove all networksPaul Holzinger2022-02-03
| | | | | | | | | | | | | | | podman system prune should also remove all networks. When we want to users to migrate to the new network stack we recommend to run podman system reset. However this did not remove networks and if there were still networks around we would continue to use cni since this was considered an old system. There is one exception for the default network. It should not be removed since this could cause other issues when it no longer exists. The network backend detection logic ignores the default network so this is fine.

* rename rootless cni ns to rootless netnsPaul Holzinger2021-11-05
| | | | | | | | | | | | Since we want to use the rootless cni ns also for netavark we should pick a more generic name. The name is now "rootless network namespace" or short "rootless netns". The rename might cause some issues after the update but when the all containers are restarted or the host is rebooted it should work correctly. Signed-off-by: Paul Holzinger <pholzing@redhat.com>

* podman unshare keep exit codePaul Holzinger2021-09-10
| | | | | | | | | | | | | | In case the command inside the podman unshare env failed podman unshare always exits with 125 and prints `Error: exit status 125`. This is a bad user experience and makes it difficult to use in scripts which could expect certain exit codes. This commit makes sure podman unshare uses the same exit code as the command and does not print the useless `exit status X` message. Also to match podman run/exec it should return 126 for EPERM and 127 for ENOENT. Signed-off-by: Paul Holzinger <pholzing@redhat.com>

* podman service reaperPaul Holzinger2021-07-02
| | | | | | | | | | | | | | | | | | | | | | | | Add a new service reaper package. Podman currently does not reap all child processes. The slirp4netns and rootlesskit processes are not reaped. The is not a problem for local podman since the podman process dies before the other processes and then init will reap them for us. However with podman system service it is possible that the podman process is still alive after slirp died. In this case podman has to reap it or the slirp process will be a zombie until the service is stopped. The service reaper will listen in an extra goroutine on SIGCHLD. Once it receives this signal it will try to reap all pids that were added with `AddPID()`. While I would like to just reap all children this is not possible because many parts of the code use `os/exec` with `cmd.Wait()`. If we reap before `cmd.Wait()` things can break, so reaping everything is not an option. [NO TESTS NEEDED] Fixes #9777 Signed-off-by: Paul Holzinger <pholzing@redhat.com>

* Add go template shell completion for --formatPaul Holzinger2021-04-22
| | | | | | | | | | | | | | | | | | | The --format flags accepts go template strings. I use this often but I consistently forget the field names. This commit adds a way to provide shell completion for the --format flag. It works by automatically receiving the field names with the reflect package from the given struct. This requires almost no maintenance since this ensures that we always use the correct field names. This also works for nested structs. ``` $ podman ps --format "{{.P" {{.Pid}} {{.PIDNS}} {{.Pod}} {{.PodName}} {{.Ports}} ``` NOTE: This only works when you use quotes otherwise the shell does not provide completions. Also this does not work for fish at the moment. Signed-off-by: Paul Holzinger <paul.holzinger@web.de>
