* move go module to v2Valentin Rothberg2020-07-06
| | | | | | | | | | | | | | | With the advent of Podman 2.0.0 we crossed the magical barrier of go modules. While we were able to continue importing all packages inside of the project, the project could not be vendored anymore from the outside. Move the go module to new major version and change all imports to `github.com/containers/libpod/v2`. The renaming of the imports was done via `gomove` [1].

* When refreshing after a reboot, force lock allocationMatthew Heon2019-05-06
| | | | | | | | | | | | | | After a reboot, when we refresh Podman's state, we retrieved the lock from the fresh SHM instance, but we did not mark it as allocated to prevent it being handed out to other containers and pods. Provide a method for marking locks as in-use, and use it when we refresh Podman state after a reboot. Fixes #2900 Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* 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 initial version of renumber backendMatthew Heon2019-02-21
| | | | | | | | | Renumber is a way of renumbering container locks after the number of locks available has changed. For now, renumber only works with containers. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

* Remove runtime lockDir and add in-memory lock managerMatthew Heon2019-01-04
| | | | | | | | | Remove runtime's lockDir as it is no longer needed after the lock rework. Add a trivial in-memory lock manager for unit testing Signed-off-by: Matthew Heon <matthew.heon@gmail.com>

* Refactor locks package to build on non-LinuxMatthew Heon2019-01-04
Move SHM specific code into a subpackage. Within the main locks package, move the manager to be linux-only and add a non-Linux unsupported build file. Signed-off-by: Matthew Heon <matthew.heon@gmail.com>
