* Do not fetch pod and ctr State on retrieval in BoltMatthew Heon2018-07-31
| | | | | | | | | | | | | | | | | It's not necessary to fill in state immediately, as we'll be overwriting it on any API call accessing it thanks to syncContainer(). It is also causing races when we fetch it without holding the container lock (which syncContainer() does). As such, just don't retrieve the state on initial pull from the database with Bolt. Also, refactor some Linux-specific netns handling functions out of container_internal_linux.go into boltdb_linux.go.

* Update documentation for the State interfaceMatthew Heon2018-07-24
| | | | | | | Include details on how namespaces interact with the state. Signed-off-by: Matthew Heon <matthew.heon@gmail.com>
* Add constraint that dependencies must be in the same nsMatthew Heon2018-07-24
| | | | | | | Dependency containers must be in the same namespace, to ensure there are never problems resolving a dependency. Signed-off-by: Matthew Heon <matthew.heon@gmail.com>

* Add pod stateMatthew Heon2018-05-17
| | | | | | | | | | Add a mutable state to pods, and database backend sutable for modifying and updating said state. Signed-off-by: Matthew Heon <matthew.heon@gmail.com> Closes: #784 Approved by: rhatdan
* Containers in a pod can only join namespaces in that podMatthew Heon2018-02-12
| | | | | | | | | | | | | | This solves some dependency problems in the state, and makes sense from a design standpoint. Containers not in a pod can still depend on the namespaces of containers joined to a pod, which we might also want to change in the future.

* Tear out pod containers map. Instead rely on stateMatthew Heon2018-02-09
| | | | | | | | | | This ensures that there is only one canonical place where containers in a pod are stored, in the state itself. Signed-off-by: Matthew Heon <matthew.heon@gmail.com> Closes: #268 Approved by: rhatdan
* Change handling for pods in libpod stateMatthew Heon2018-01-17
| | | | | | | | | | Add new functions to update pods and add/remove containers from them Use these new functions in place of manually modifying pods Signed-off-by: Matthew Heon <matthew.heon@gmail.com> Closes: #229 Approved by: rhatdan

* Add ability for states to track container dependenciesMatthew Heon2018-01-16
| | | | | | | | | | | Also prevent containers with dependencies from being removed from in memory states. SQLite already enforced this via FOREIGN KEY constraints. Signed-off-by: Matthew Heon <matthew.heon@gmail.com> Closes: #220 Approved by: rhatdan
* Add ability to refresh state in DBMatthew Heon2017-12-07
