* Remove excessive error wrappingKir Kolyshkin2020-10-05
| | | | | | | | | | | | | | | | | In case os.Open[File], os.Mkdir[All], ioutil.ReadFile and the like fails, the error message already contains the file name and the operation that fails, so there is no need to wrap the error with something like "open %s failed". While at it - replace a few places with os.Open, ioutil.ReadAll with ioutil.ReadFile. - replace errors.Wrapf with errors.Wrap for cases where there are no %-style arguments.

| * remote: fix name and ID collisions of containers and podsValentin Rothberg2020-10-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix the look up of containers and pods in the remote client. User input can refer to both, names or IDs of containers and pods, so there is a fair chance of collisions (e.g., "c1" name with a "c1...." ID). Those collisions are well handled (and battle tested) in the local client which is directly using the libpod backend. Hence, the remote client should not attempt to introduce its own logic to prevent bugs and divergence between the local and the remote clients. To prevent collisions such as in #7837, do a container/pod inspect on the user-provided input to find the corresponding ID and eventually do full ID comparisons to avoid potential collisions with names. Note that this has a cost that I am not entirely happy with. Looking at issue #7837, the collisions are happening when removing the two containers. Remote container removal is now very chatty with the server as it first queries for all containers, then iterates over the provided names or IDs and does a remote inspect to figure out the IDs and find a matching container object. However, remote removal could just pass the names and IDs directly to the batch removal endpoint. Querying for all containers could be prevented if the batch removal endpoint would remove all if the slice is empty. In other words, the bug is fixed but there's room for performance improvements.

* fix remote untagValentin Rothberg2020-09-30
| | | | | | | | | | | | | | Fix the remote client to untag all tags of the specified image. Instead of querying the image on the client side, support the case where both, repo and tag, are empty and remove all tags. Reuse the ABI implementation where possible. In retrospective, the libpod untag endpoint should support a slice of strings to batch remove tags rather than reaching out for each tag individually. Enable the skipped test.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After attaching to a container, we wait for the container to finish and return its exit code. Waiting for the container may not always succeed, for instance, when the container has been force removed by another process. In such case, we have to look at the *last* container-exit event. Also refactor the `ContainerRun` method a bit to return early on errors and de-spaghetti the code. Enable the remote-disabled system test.

* 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.

Or you might want to just use the executables on the image without running it in a container. The image is mounted readonly since we do not want people changing images.

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.

| * | Fix podman inspect on overlapping/missing objectsMatthew Heon2020-06-16
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This started as a small fix to `podman inspect` where a container and image, with the same name/tag, were present, and `podman inspect` was run on that name. `podman inspect` in 1.9 (and `docker inspect`) will give you the container; in v2.0, we gave the image. This was an easy fix (just reorder how we check for image/container). Unfortunately, in the process of testing this fix, I determined that we regressed in a different area. When you run inspect on a number of containers, some of which do not exist, `podman inspect` should return an array of inspect results for the objects that exist, then print a number of errors, one for each object that could not be found. We were bailing after the first error, and not printing output for the containers that succeeded. (For reference, this applied to images as well). This required a much more substantial set of changes to properly handle - signatures for the inspect functions in ContainerEngine and ImageEngine, plus the implementations of these interfaces, plus the actual inspect frontend code needed to be adjusted to use this.
