* Change attach to accept a struct containing streamsMatthew Heon2018-04-13
| | | | | | | | | | | Comparing Go interfaces, like io.Reader, to nil does not work. As such, we need to include a bool with each stream telling whether to attach to it. Signed-off-by: Matthew Heon <matthew.heon@gmail.com> Closes: #608 Approved by: baude
* Changes to attach to enable per-stream attachingMatthew Heon2018-04-13
| | | | | | | | | | This allows us to attach to attach to just stdout or stderr or stdin, or any combination of these. Signed-off-by: Matthew Heon <matthew.heon@gmail.com> Closes: #608 Approved by: baude

* Force host UID/GID mapping when creating containersNalin Dahyabhai2018-04-12
| | | | | | | | | | Until we can handle running containers which use UID/GID mappings, make sure that we always create containers that use the host mappings. Signed-off-by: Nalin Dahyabhai <nalin@redhat.com> Closes: #609 Approved by: baude

* Do not lock all containers during pod startMatthew Heon2018-04-12
| | | | | | | | | | This solves a nasty locking issue with getting the path of namespaces for dependencies Signed-off-by: Matthew Heon <matthew.heon@gmail.com> Closes: #600 Approved by: rhatdan
* Containers transitioning to stop should not break statsbaude2018-04-11
| | | | | | | | | | | | When a container is transitioning from running to stopped and stats is runnings, we should not break stats if we are unable to get stats for that container. Resolves: #598 Signed-off-by: baude <bbaude@redhat.com> Closes: #599 Approved by: mheon

* Functionality changes to the following flagsumohnani82018-04-06
| | | | | | | | | | | | | | | | | | | --group-add --blkio-weight-device --device-read-bps --device-write-bps --device-read-iops --device-write-iops --group-add now supports group names as well as the gid associated with them. All the --device flags work now with moderate changes to the code to support both bps and iops. Added tests for all the flags.

* Prevent a potential race when stopping containersMatthew Heon2018-04-04
| | | | | | | | | | | If sending a signal fails, check if the container is alive. If it is not, it probably stopped on its own before we could send the signal, so don't error out. Signed-off-by: Matthew Heon <matthew.heon@gmail.com> Closes: #591 Approved by: rhatdan
* Only allocate tty when -tbaude2018-04-03
| | | | | | | | | | | In our ezrly development, we always allocated a tty when not -d. Now we should only allocated when the user asks for it. Resolves: #573 Signed-off-by: baude <bbaude@redhat.com> Closes: #574 Approved by: rhatdan

* Refactor dependency checks from init() into public APIMatthew Heon2018-04-03
| | | | | | | | | | | | | Instead of checking during init(), which could result in major locking issues when used with pods, make our dependency checks in the public API instead. This avoids doing them when we start pods (where, because of the dependency graph, we can reasonably say all dependencies are up before we start a container). Signed-off-by: Matthew Heon <matthew.heon@gmail.com> Closes: #577 Approved by: rhatdan
* Do not require Init() before Start()Matthew Heon2018-04-03

* Don't return an ImageConfig when creating storageMatthew Heon2018-04-02
| | | | | | | | | | | | We don't use it directly, we aren't going to cache it in the DB, and when we do use it (image volumes) we might well be in a different process (podman create -> podman start). No point in keeping it around. Signed-off-by: Matthew Heon <matthew.heon@gmail.com> Closes: #571 Approved by: rhatdan
* More gracefully handle unexpected storage deletionMatthew Heon2018-04-02
| | | | | | | | | | | | | | | | | | We have other tools using containers/storage. They can delete our containers in c/storage without us knowing. Try and handle this better by warning instead of erroring when delete our storage and it is already gone. This does not handle cases where libpod thinks the container is mounted, but it is not. This is harder to check for, because c/storage Mount() and Unmount() take a layer, image, or container and that complicates our "container no longer exists" question. Further work is needed here.

* Allow sha256: prefix for inputbaude2018-03-29

* Remove a loop in container graphMatthew Heon2018-03-29
| | | | | | | | | | | Instead of looping to find containers with no dependencies, maintain a map of them and remove entries as we add dependency edges. Signed-off-by: Matthew Heon <matthew.heon@gmail.com> Closes: #557 Approved by: rhatdan

* Prevent ctrs not in pods from depending on pod ctrsMatthew Heon2018-03-29
| | | | | | | | | | | | | Containers in pods cannot depend on containers outside of the same pod. Make the reverse true as well - containers not in pods cannot depend on containers in pods. This greatly simplifies our dependency handling, as we can guarantee that removing a pod will not encounter dependency issues.

* Remove current SQLite DB driverMatthew Heon2018-03-26
| | | | | | | | | | | | The SQLite DB backend has become an unmanageable nightmare.

* Removing tagged images change in behaviorbaude2018-03-22
| | | | | | | | | | | | | | | An image name is really just a tag. When an image has multiple tags, we should be able to "delete" the one of its tags without harm. In this case, the "delete' is really a form of Untag (removing the tag from the image). If an image has multiple tags and the user tries to delete by ID without force, this should be denied because when you delete by ID there is no distinguishing it like image tags.
