* 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 namespaces and initial constraints to databaseMatthew Heon2018-07-24
| | | | | | | | Add basic awareness of namespaces to the database. As part of this, add constraints so containers can only be added to pods in the same namespace. Signed-off-by: Matthew Heon <matthew.heon@gmail.com>
* Add container and pod namespaces to configsMatthew Heon2018-07-24
| | | | | | | Libpod namespaces are a way to logically separate groups of pods and containers within the state. Signed-off-by: Matthew Heon <matthew.heon@gmail.com>
* Update container Mounted() and Mountpoint() functionsMatthew Heon2018-07-24
| | | | | | | | | | | | | | | | Addresses a regression in `podman mount` due to our mount changes to allow concurrency by letting c/storage handle mounting and unmounting. Combine Mounted() and Mountpoint() into one function and query c/storage directly to ensure we get accurate information. Fixes: #1143 Signed-off-by: Matthew Heon <matthew.heon@gmail.com> Closes: #1144 Approved by: baude
* Use the result of reference.Parse when checking for digests.Miloslav Trmač2018-07-23
| | | | | | | | | | | | No need to do a separate string search when reference.Parse has already determined this. Changes behavior: non-SHA256 digest formats are now recognized as well. Signed-off-by: Miloslav Trmač <mitr@redhat.com> Closes: #1112 Approved by: rhatdan

* Make Image.HasShaInInputName to an independent local functionMiloslav Trmač2018-07-23
| | | | | | | | | | | | The functionality only depends on Image.InputName, and we will want to make the only user of this independent of the fairly complex Image type. Should not change behavior. Signed-off-by: Miloslav Trmač <mitr@redhat.com> Closes: #1112 Approved by: rhatdan
* Split createNamesToPull into ref{Names,Pairs}FromPossiblyUnqualifiedNameMiloslav Trmač2018-07-23
| | | | | | | | | | | | | | One part creates []*pullRefName; the other just trivially converts it into []*pullRefPair. Also use much more explicit names to explain the functionality. Should not change behavior. Signed-off-by: Miloslav Trmač <mitr@redhat.com> Closes: #1112 Approved by: rhatdan

* Rename nameToPull to pullRefNameMiloslav Trmač2018-07-23

* Rename pullStruct to pullRefPairMiloslav Trmač2018-07-23
| | | | | | | | | | | | "Struct" is meaningless, and we will need the "reference pair" mentioned to distinguish srcRef+dstRef from srcRef+dstName. Should not change behavior. Signed-off-by: Miloslav Trmač <mitr@redhat.com> Closes: #1112 Approved by: rhatdan
* Replace optional nameToPull.shaPullName with mandatory dstNameMiloslav Trmač2018-07-23
| | | | | | | | | | | | | This consolidates the shaPullName logic into a single place, (and eliminates the unclear shaPullName member name completely). The resulting nameToPull will shortly be more generally useful. Should not change behavior. Signed-off-by: Miloslav Trmač <mitr@redhat.com> Closes: #1112 Approved by: rhatdan
* Introduce nameToPull, move shaPullName in thereMiloslav Trmač2018-07-23
| | | | | | | | | | | | | | | | | shaPullName is only used internally in createNamesToPull; so, introduce a nameToPull as a variant of pullStruct which has shaPullName (and does not have destRef). Eventually, we want to split pullStruct preparation into easily-testable store-independent name preparation, and a store-dependent and difficult-to-test but trivial conversion using StorageTransport.ParseStoreReference. Should not change behavior. Signed-off-by: Miloslav Trmač <mitr@redhat.com> Closes: #1112 Approved by: rhatdan

* Remove Image.isShortNameMiloslav Trmač2018-07-23
| | | | | | | | | | | | It has no users, and it depends on the incorrect imageParts.hasRegistry. So, just drop it instead of worrying whether it is OK to change its semantics. Should not change behavior. Signed-off-by: Miloslav Trmač <mitr@redhat.com> Closes: #1112 Approved by: rhatdan
* Inline getTags into its only userMiloslav Trmač2018-07-23
| | | | | | | | | | | | This also eliminates a duplicate call to reference.Parse() and removes an impossible erorr path. Should not change behavior. Signed-off-by: Miloslav Trmač <mitr@redhat.com> Closes: #1112 Approved by: rhatdan

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently we unmount storage that is still in use. We should not be unmounting storeage that we mounted via a different command or by podman mount. This change relies on containers/storage to umount keep track of how many times the storage was mounted before really unmounting it from the system. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>

* | podman-top: use containers/psgoValentin Rothberg2018-07-19
|/ | | | | | | | | | | | | | | | | Use github.com/containers/psgo instead of execing `ps (1)`. The psgo library enables a much more flexible interface with respect to which data to be printed (e.g., capabilities, seccomp mode, PID, PCPU, etc.) while the output can be parsed reliably. The library does not use ps (1) but parses /proc and /dev instead. To list the processes of a given container, psgo will join the mount namespace of the given container and extract all data from there. Notice that this commit breaks compatibility with docker-top.

* 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.

| | | | | | | | | | | | | | | | 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.
