* pkg/ctime: Factor libpod/finished* into a separate packageW. Trevor King2018-07-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This removes some boilerplate from the libpod package, so we can focus on container stuff there. And it gives us a tidy sub-package for focusing on ctime extraction, so we can focus on unit testing and portability of the extraction utility there. For the unsupported implementation, I'm falling back to Go's ModTime [1]. That's obviously not the creation time, but it's likely to be closer than the uninitialized Time structure from cc6f0e85 (more changes to compile darwin, 2018-07-04, #1047). Especially for our use case in libpod/oci, where we're looking at write-once exit files. The test is more complicated than I initially expected, because on Linux filesystem timestamps come from a truncated clock without interpolation [2] (and network filesystems can be completely decoupled [3]). So even for local disks, creation times can be up to a jiffie earlier than 'before'. This test ensures at least monotonicity by creating two files and ensuring the reported creation time for the second is greater than or equal to the reported creation time for the first. It also checks that both creation times are within the window from one second earlier than 'before' through 'after'. That should be enough of a window for local disks, even if the kernel for those systems has an abnormally large jiffie. It might be ok on network filesystems, although it will not be very resilient to network clock lagging behind the local system clock.

* Remove per-container CGroup parentsMatthew Heon2018-07-06
| | | | | | | | | | | | | | | | | | | Originally, it seemed like a good idea to place Conmon and the container it managed under a shared CGroup, so we could manage the two together. It's become increasingly clear that this is a potential performance sore point, gains us little practical benefit in managing Conmon, and adds extra steps to container cleanup that interfere with Conmon postrun hooks. Revert back to a shared CGroup for conmon processes under the CGroup parent. This will retain per-pod conmon CGroups as well if the pod is set to create a CGroup and act as CGroup parent for its containers.

* more changes to compile darwinbaude2018-07-05
| | | | | | | | | | | | | | | | this should represent the last major changes to get darwin to **compile**. again, the purpose here is to get darwin to compile so that we can eventually implement a ci task that would protect against regressions for darwin compilation. i have left the manual darwin compilation largely static still and in fact now only interject (manually) two build tags to assist with the build. trevor king has great ideas on how to make this better and i will defer final implementation of those to him.

* Returning joining namespace error should not be fatalDaniel J Walsh2018-06-29
| | | | | | | | | | | | | | | | | | | | | | I got my database state in a bad way by killing a hanging container. It did not setup the network namespace correctly listing/remove bad containers becomes impossible. podman run alpine/nginx ^c got me in this state.

* Errors from closing a netns on removal from DB are nonfatalMatthew Heon2018-06-19
| | | | | | | | | | | | | | | | Upon updating a container, if its network namespace has been removed, we attempt to clean up the network namespace locally, to ensure we don't leave hanging file descriptors. This triggers cleanup code which assumes the network namespace still exists, but it almost certainly was removed by whoever removed it from the database. As such, we end up with unavoidable errors if we don't want to leak FDs. Make these errors nonfatal and log them because of this.
