* Unconditionally retrieve pod names via APIMatthew Heon2020-08-10
| | | | | | | | | | | | | | | | | | The ListContainers API previously had a Pod parameter, which determined if pod name was returned (but, notably, not Pod ID, which was returned unconditionally). This was fairly confusing, so we decided to deprecate/remove the parameter and return it unconditionally. To do this without serious performance implications, we need to avoid expensive JSON decodes of pod configuration in the DB. The way our Bolt tables are structured, retrieving name given ID is actually quite cheap, but we did not expose this via the Libpod API. Add a new GetName API to do this.

| * image list: speed upValentin Rothberg2020-08-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Listing images has shown increasing performance penalties with an increasing number of images. Unless `--all` is specified, Podman will filter intermediate images. Determining intermediate images has been done by finding (and comparing!) parent images which is expensive. We had to query the storage many times which turned it into a bottleneck. Instead, create a layer tree and assign one or more images to nodes that match the images' top layer. Determining the children of an image is now exponentially faster as we already know the child images from the layer graph and the images using the same top layer, which may also be considered child images based on their history. On my system with 510 images, a rootful image list drops from 6 secs down to 0.3 secs. Also use the tree to compute parent nodes, and to filter intermediate images for pruning.

| | | | | | | | | | | | | | | | | | | | | | This change ensures that we pull volume bind specification strings from the correct spot in the POSTed data when creating containers.

* | events endpoint: backwards compat to old typeValentin Rothberg2020-07-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The versions Docker that the compat endpoints currently support are using another type for the `filters` parameter than later versions of Docker, which the libpod/events endpoint is also using.

* | events endpoint: fix panic and race conditionValentin Rothberg2020-07-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix a potential panic in the events endpoint when parsing the filters parameter. Values of the filters map might be empty, so we need to account for that instead of uncondtitionally accessing the first item. Also apply a similar for race conditions as done in commit f4a2d25c0fca: Fix a race that could cause read errors to be masked. Masking such errors is likely to report red herrings since users don't see that reading failed for some reasons but that a given event could not be found. Another race was the handler closing event channel, which could lead to two kinds of panics: double close, send to close channel. The backend takes care of that. However, make sure that the backend stops working in case the context has been cancelled. Fixes: #6899 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

The code is mostly lifted from the `libpod` API handlers but decodes and constructs data using types defined in the docker API package. Some notable support caveats with the current implementation: * we don't return the nullable `Status` or `UsageData` keys when returning volume information for inspect and create endpoints * we don't support filters when pruning * we return a fixed `0` for the `SpaceReclaimed` key when pruning since we have no insight into how much space was freed from runtime Signed-off-by: Matt Brindley <58414429+maybe-sybr@users.noreply.github.com>

* Set syslog for exit commands on log-level=debugMatthew Heon2020-06-24
| | | | | | | | | | | | | | | | We have a flag, --syslog, for telling logrus to log to syslog as well as to the terminal. Previously, this flag also set the exit command for containers to use `--syslog` (otherwise all output from exit commands is lost). I attempted to replicate this with Podman v2.0, but quickly ran into circular import hell (the flag is defined in cmd/podman, I needed it in cmd/podman/containers, cmd/podman imports cmd/podman/containers already, etc). Instead, let's just set the syslog flag automatically on `--log-level=debug` so we log exit commands automatically when debug-level logs are requested. This is consistent with Conmon and seems to make sense. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

* Allow recursive dependency start with Init()Matthew Heon2020-06-18
| | | | | | | | | | | | | | | | | | | | As part of APIv2 Attach, we need to be able to attach to freshly created containers (in ContainerStateConfigured). This isn't something Libpod is interested in supporting, so we use Init() to get the container into ContainerStateCreated, in which attach is possible. Problem: Init() will fail if dependencies are not started, so a fresh container in a fresh pod will fail. The simplest solution is to extend the existing recursive start code from Start() to Init(), allowing dependency containers to be started when we initialize the container (optionally, controlled via bool). Also, update some comments in container_api.go to make it more clear how some of our major API calls work. Fixes #6646 Signed-off-by: Matthew Heon <mheon@redhat.com>

* | Re-add resource limit warnings to SpecgenMatthew Heon2020-06-16
|/ | | | | | | | | | | | | | | | | | | | | | These were part of Podman v1.9, but were lost in the transition to using Specgen to create containers. Most resource limits are checked via the sysinfo package to ensure they are safe to use (the cgroup is mounted, kernel support is present, etc) and removed if not safe. Further, bounds checks are performed to ensure that values are valid. Ensure these warnings are printed client-side when they occur. This part is a little bit gross, as it happens in pkg/infra and not cmd/podman, which is largely down to how we implemented `podman run` - all the work is done in pkg/infra and it returns only once the container has exited, and we need warnings to print *before* the container runs. The solution here, while inelegant, avoid the need to extensively refactor our handling of run. Should fix blkio-limit warnings that were identified by the FCOS test suite.
