* Add ContainerStateRemovingMatthew Heon2019-11-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When Libpod removes a container, there is the possibility that removal will not fully succeed. The most notable problems are storage issues, where the container cannot be removed from c/storage. When this occurs, we were faced with a choice. We can keep the container in the state, appearing in `podman ps` and available for other API operations, but likely unable to do any of them as it's been partially removed. Or we can remove it very early and clean up after it's already gone. We have, until now, used the second approach. The problem that arises is intermittent problems removing storage. We end up removing a container, failing to remove its storage, and ending up with a container permanently stuck in c/storage that we can't remove with the normal Podman CLI, can't use the name of, and generally can't interact with. A notable cause is when Podman is hit by a SIGKILL midway through removal, which can consistently cause `podman rm` to fail to remove storage. We now add a new state for containers that are in the process of being removed, ContainerStateRemoving. We set this at the beginning of the removal process. It notifies Podman that the container cannot be used anymore, but preserves it in the DB until it is fully removed. This will allow Remove to be run on these containers again, which should successfully remove storage if it fails. Fixes #3906 Signed-off-by: Matthew Heon <mheon@redhat.com>
* add libpod/configValentin Rothberg2019-10-31
| | | | | | | | | | | | Refactor the `RuntimeConfig` along with related code from libpod into libpod/config. Note that this is a first step of consolidating code into more coherent packages to make the code more maintainable and less prone to regressions on the long runs. Some libpod definitions were moved to `libpod/define` to resolve circular dependencies. Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
* Ensure volumes can be removed when they fail to unmountMatthew Heon2019-10-14
| | | | | | | | | | | | | | | | | | | | Also, ensure that we don't try to mount them without root - it appears that it can somehow not error and report that mount was successful when it clearly did not succeed, which can induce this case. We reuse the `--force` flag to indicate that a volume should be removed even after unmount errors. It seems fairly natural to expect that --force will remove a volume that is otherwise presenting problems. Finally, ignore EINVAL on unmount - if the mount point no longer exists our job is done.

* rm: add containers eviction with `rm --force`Marco Vedovati2019-09-25
| | | | | | | | | Add ability to evict a container when it becomes unusable. This may happen when the host setup changes after a container creation, making it impossible for that container to be used or removed. Evicting a container is done using the `rm --force` command.

* Fix exit code failureDaniel J Walsh2019-09-17
| | | | | | Be less precise on the exit code and lot the exit code to the journal when it fails. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>
* Use exit code constantsDaniel J Walsh2019-09-12
| | | | | | | We have leaked the exit number codess all over the code, this patch removes the numbers to constants. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>
* Add support for launching containers without CGroupsMatthew Heon2019-09-10
| | | | | | | This is mostly used with Systemd, which really wants to manage CGroups itself when managing containers via unit file. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* Correctly report errors on unmounting SHMMatthew Heon2019-09-05
| | | | | | | | | | | When we fail to remove a container's SHM, that's an error, and we need to report it as such. This may be part of our lingering storage woes. Also, remove MNT_DETACH. It may be another cause of the storage removal failures. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

* move editing of exitCode to runtimePeter Hunt2019-07-23
| | | | | | | | | There's no way to get the error if we successfully get an exit code (as it's just printed to stderr instead). instead of relying on the error to be passed to podman, and edit based on the error code, process it on the varlink side instead Also move error codes to define package Signed-off-by: Peter Hunt <pehunt@redhat.com>

* remove libpod from mainbaude2019-06-25
the compilation demands of having libpod in main is a burden for the remote client compilations. to combat this, we should move the use of libpod structs, vars, constants, and functions into the adapter code where it will only be compiled by the local client. this should result in cleaner code organization and smaller binaries. it should also help if we ever need to compile the remote client on non-Linux operating systems natively (not cross-compiled).
