* Events for containers in pods now include the pod's IDMatthew Heon2022-09-22
| | | | | | | | | | This allows tools like Cockpit to know that the pod in question has also been updated, so they can refresh the list of containers in the pod. Fixes #15408 Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* Replace deprecated ioutilChris Evich2022-09-20
| | | | | | | | | | Package `io/ioutil` was deprecated in golang 1.16, preventing podman from building under Fedora 37. Fortunately, functionality identical replacements are provided by the packages `io` and `os`. Replace all usage of all `io/ioutil` symbols with appropriate substitutions according to the golang docs.

* events: Fix spelling of newNullEventerDoug Rabson2022-09-13
| | | | | | | | | | | | | | | This function changed from public to private which broke the FreeBSD build. Sadly, adding FreeBSD to the cross build isn't currently possible since github.com/godbus/dbus relies on cgo on FreeBSD. I've tried to fix this upstream but my PR is going nowhere - I think this dependency is only needed for systemd which isn't a thing on FreeBSD so it might be possible to work around the problem in libpod by making the systemd code conditional on linux.

* set default EventsLogFilePath on first runPaul Holzinger2022-09-12
| | | | | | | | The current code only sets EventsLogFilePath when the tmp is overwritten from the db. We should always set the default when no path was set in containers.conf. Signed-off-by: Paul Holzinger <pholzing@redhat.com>
* event backend journald: fix problem with empty journalPaul Holzinger2022-09-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently podman events will just fail with `Error: failed to get journal cursor: failed to get cursor: cannot assign requested address` when the journal contains zero podman events. The problem is that we are using the journal accessors wrong. There is no need to call GetCursor() and compare them manually. The Next() return an integer which tells if it moved to the next or not. This means the we can remove GetCursor() which would fail when there is no entry. This also includes another bug fix. Previously the logic called Next() twice for the first entry which caused us to miss the first entry. To reproduce this issue you can run the following commands: ``` sudo journalctl --rotate sudo journalctl --vacuum-time=1s ``` Note that this will delete the full journal. Now run podman events and it fails but with this patch it works. Now generate a single event, i.e. podman pull alpine, and run podman events --until 1s. I am not sure how to get a reliable test into CI, I really do not want to delete the journal and developer or CI systems.

* event backend none: return an error when reading eventsPaul Holzinger2022-09-12
| | | | | | | | | podman --events-backend none events should return with an error since it will never be able to actually list events. Fixes part three of #15688 Signed-off-by: Paul Holzinger <pholzing@redhat.com>
* fix hang with podman events file loggerPaul Holzinger2022-09-12
| | | | | | | | | | | | | podman --events-backend file events --stream=false should never hang. The problem is that our tail library will wait for the file to be created which makes sense when we do not run with --stream=false. To fix this we can just always create the file when the logger is initialized. This would also help to report errors early on in case the file is not accessible.

* fix goroutine leaks in events and logs backendPaul Holzinger2022-07-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When running a single podman logs this is not really important since we will exit when we finish reading the logs. However for the system service this is very important. Leaking goroutines will cause an increased memory and CPU ussage over time. Both the the event and log backend have goroutine leaks with both the file and journald drivers. The journald backend has the problem that journal.Wait(IndefiniteWait) will block until we get a new journald event. So when a client closes the connection the goroutine would still wait until there is a new journal entry. To fix this we just wait for a maximum of 5 seconds, after that we can check if the client connection was closed and exit correctly in this case. For the file backend we can fix this by waiting for either the log line or context cancel at the same time. Currently it would block waiting for new log lines and only check afterwards if the client closed the connection and thus hang forever if there are no new log lines. [NO NEW TESTS NEEDED] I am open to ideas how we can test memory leaks in CI. To test manually run a container like this: `podman run --log-driver $driver --name test -d alpine sh -c 'i=1; while [ "$i" -ne 1000 ]; do echo "line $i"; i=$((i + 1)); done; sleep inf'` where `$driver` can be either `journald` or `k8s-file`. Then start the podman system service and use: `curl -m 1 --output - --unix-socket $XDG_RUNTIME_DIR/podman/podman.sock -v 'http://d/containers/test/logs?follow=1&since=0&stderr=1&stdout=1' &>/dev/null` to get the logs from the API and then it closes the connection after 1 second. Now run the curl command several times and check the memory usage of the service. Fixes #14879 Signed-off-by: Paul Holzinger <pholzing@redhat.com>

* Add ExecDied event and use it to retrieve exit codesMatthew Heon2021-06-10
| | | | | | | | | | | | | | | | When making Exec Cleanup processes mandatory, I introduced a race wherein attached exec sessions could be cleaned up and removed by the cleanup process before the frontend had a chance to get their exit code. Fortunately, we've dealt with this issue before in containers, and the same solution can be applied here. I added an event for an exec session's process exiting, `exec_died` (Docker has an identical event, so this actually improves our compatibility there) that includes the exit code of the exec session. If the race happens and the exec session no longer exists when we go to remove it, pick up exit code from the event and exit cleanly. Signed-off-by: Matthew Heon <mheon@redhat.com>

* podman events allow future time for --untilPaul Holzinger2020-12-11
| | | | | | | | | | | | | | | | | The podman events aren't read until the given timestamp if the timestamp is in the future. It just reads all events until now and exits afterwards. This does not make sense and does not match docker. The correct behavior is to read all events until the given time is reached. This fixes a bug where the wrong event log file path was used when running first time with a new storage location. Fixes #8694 This also fixes the events api endpoint which only exited when an error occurred. Otherwise it just hung after reading all events. Signed-off-by: Paul Holzinger <paul.holzinger@web.de>
* rewrite podman-cpValentin Rothberg2020-12-04
| | | | | | | | | | | | | | | | | | | | | | | | * Add a new `pkg/copy` to centralize all container-copy related code. * The new code is based on Buildah's `copier` package. * The compat `/archive` endpoints use the new `copy` package. * Update docs and an several new tests. * Includes many fixes, most notably, the look-up of volumes and mounts. Breaking changes: * Podman is now expecting that container-destination paths exist. Before, Podman created the paths if needed. Docker does not do that and I believe Podman should not either as it's a recipe for masking errors. These errors may be user induced (e.g., a path typo), or internal typos (e.g., when the destination may be a mistakenly unmounted volume). Let's keep the magic low for such a security sensitive feature. Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

* 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>
* Remove all instances of named return "err" from LibpodMatthew Heon2020-07-09
| | | | | | | | | | | | | | | | | This was inspired by https://github.com/cri-o/cri-o/pull/3934 and much of the logic for it is contained there. However, in brief, a named return called "err" can cause lots of code confusion and encourages using the wrong err variable in defer statements, which can make them work incorrectly. Using a separate name which is not used elsewhere makes it very clear what the defer should be doing. As part of this, remove a large number of named returns that were not used anywhere. Most of them were once needed, but are no longer necessary after previous refactors (but were accidentally retained). Signed-off-by: Matthew Heon <matthew.heon@pm.me>
