* Fix podman ps -lDaniel J Walsh2020-09-09
| | | | | | | | Currently the --latest flag is ignored by podman ps command. Fixes https://bugzilla.redhat.com/show_bug.cgi?id=1877182 Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>
* podman stop: do not cleanup for auto-removalValentin Rothberg2020-09-08
| | | | | | | | | | | | Do not perform a container clean up for containers configured for auto-removal (e.g., via `podman run --rm`). There is a small race window with the other process performing the removal where a clean up during podman-stop may fail since the container has already been removed and cleaned up. As the removing process will clean up the container, we don't have to do it during podman-stop. Fixes: #7384 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

* log API: add context to allow for cancellingValentin Rothberg2020-07-09
| | | | | | | | | Add a `context.Context` to the log APIs to allow for cancelling streaming (e.g., via `podman logs -f`). This fixes issues for the remote API where some go routines of the server will continue writing and produce nothing but heat and waste CPU cycles.

* 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].

* Fix `system service` panic from early hangup in eventsMatthew Heon2020-07-02
| | | | | | | | | | | | We weren't actually halting the goroutine that sent events, so it would continue sending even when the channel closed (the most notable cause being early hangup - e.g. Control-c on a curl session). Use a context to cancel the events goroutine and stop sending events. Fixes #6805 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.

* | 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.

* Add parallel operation to `podman stop`Matthew Heon2020-06-05
| | | | | | | | | | | | This is the other command that benefits greatly from being run in parallel, due to the potential 15-second timeout for containers that ignore SIGTERM. While we're at it, also clean up how stop timeout is set. This needs to be an optional parameter, so that the value set when the container is created with `--stop-timeout` will be respected. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* Add parallel execution code for container operationsMatthew Heon2020-06-05
| | | | | | | | This code will run container operations in parallel, up to a given maximum number of threads. Currently, it has only been enabled for local `podman rm` as a proof of concept. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* When stopping containers locally, ensure cleanup runsMatthew Heon2020-06-03
| | | | | | | | | | | | | The cleanup process was already running and ensuring that mounts and networking configuration was cleaned up on container stop, but this was async from the actual `podman stop` command which breaks some expectations - the container is still mounted at the end of `podman stop` and will be cleaned up soon, but not immediately. Fortunately, it's a trivial change to resolve this. Fixes #5747 Signed-off-by: Matthew Heon <matthew.heon@pm.me>

* | Enable detached exec for remoteMatthew Heon2020-06-02
|/ | | | | | | | | | | | | | | | | | | | | | | The biggest obstacle here was cleanup - we needed a way to remove detached exec sessions after they exited, but there's no way to tell if an exec session will be attached or detached when it's created, and that's when we must add the exit command that would do the removal. The solution was adding a delay to the exit command (5 minutes), which gives sufficient time for attached exec sessions to retrieve the exit code of the session after it exits, but still guarantees that they will be removed, even for detached sessions. This requires Conmon 2.0.17, which has the new `--exit-delay` flag. As part of the exit command rework, we can drop the hack we were using to clean up exec sessions (remove them as part of inspect). This is a lot cleaner, and I'm a lot happier about it. Otherwise, this is just plumbing - we need a bindings call for detached exec, and that needed to be added to the tunnel mode backend for entities. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* container stats: fix --no-stream raceValentin Rothberg2020-05-27
| | | | | | | | | Fix a race in `podman container stats` by waiting for the client to consume the data in the channel. This requires a `sync.WaitGroup` (or semaphore) in the client and to also close the channel the backend. Fixes: #6405 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
* Enable cleanup processes for detached execMatthew Heon2020-05-20
| | | | | | | | | | | | | | | | | | | | | | The cleanup command creation logic is made public as part of this and wired such that we can call it both within SpecGen (to make container exit commands) and from the ABI detached exec handler. Exit commands are presently only used for detached exec, but theoretically could be turned on for all exec sessions if we wanted (I'm declining to do this because of potential overhead). I also forgot to copy the exit command from the exec config into the ExecOptions struct used by the OCI runtime, so it was not being added. There are also two significant bugfixes for exec in here. One is for updating the status of running exec sessions - this was always failing as I had coded it to remove the exit file *before* reading it, instead of after (oops). The second was that removing a running exec session would always fail because I inverted the check to see if it was running. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* Add ability to clean up exec sessions with cleanupMatthew Heon2020-05-20
| | | | | | | | | | | | | | We need to be able to use cleanup processes to remove exec sessions as part of detached exec. This PR adds that ability. A new flag is added to `podman container cleanup`, `--exec`, to specify an exec session to be cleaned up. As part of this, ensure that `ExecCleanup` can clean up exec sessions that were running, but have since exited. This ensures that we can come back to an exec session that was running but has since stopped, and clean it up. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* Add CLI frontend for detached execMatthew Heon2020-05-20
| | | | | | | | | | | Add a new ContainerEngine method for creating a detached exec session, and wire in the frontend code to do this.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | While this commit was initially meant to fix #5847, it has turned into a bigger refactoring which I did not manage to break into smaller pieces: * Fix #5847 by refactoring the image-removal logic. * Make the api handler for image-removal use the ABI code. This way, both (i.e., ABI and Tunnel) end up using the same code. Achieving this code share required to move some code around to prevent circular dependencies. * Everything in pkg/api (excluding pkg/api/types) must now only be accessed from code using `ABISupport`. * Avoid imports from entities on handlers to prevent circular dependencies. * Move `podman system service` logic into `cmd` to prevent circular dependencies - it depends on pkg/api. * Also remove the build header from infra/abi files. It will otherwise confuse swagger and other tools; errors we cannot fix as go doesn't expose a build-tag env variable. Fixes: #5847 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
