* 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>
* events: support disjunctive filtersValentin Rothberg2021-06-02

* 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>

| | | | | | | | | | | this enables the ability to connect and disconnect a container from a given network. it is only for the compatibility layer. some code had to be refactored to avoid circular imports. additionally, tests are being deferred temporarily due to some incompatibility/bug in either docker-py or our stack.

* Improve the journal event readingPaul Holzinger2020-10-27

* filter events by labelsbaude2020-10-23

* APIv2 compatibility network connect|disconnectbaude2020-10-22
| | | | | | Add endpoints for the compat layer for network connect and disconnect. As of now, these two endpoints do nothing to change the network state of a container. They do some basic data verification and return the proper 200 response. This at least allows for scripts to work on the compatibility layer instead of getting 404s. Signed-off-by: baude <bbaude@redhat.com>
* add event for image buildBrent Baude2020-08-12
| | | | | | | | upon image build completion, a new image type event is written for "build". more intricate details, like pulling an image, that might be done by build must be implemented in different vendored packages only after libpod is split from podman.

* 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>
* 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>
* Poll on events for file readingBrent Baude2020-06-19
| | | | | | | | When multiple connections are monitoring events via the remote API, the inotify in the hpcloud library seems unable to consistently send events. Switching from inotify to poll seems to clear this up. Fixes: #6664 Signed-off-by: Brent Baude <bbaude@redhat.com>

* auto updatesValentin Rothberg2020-03-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support to auto-update containers running in systemd units as generated with `podman generate systemd --new`. `podman auto-update` looks up containers with a specified "io.containers.autoupdate" label (i.e., the auto-update policy). If the label is present and set to "image", Podman reaches out to the corresponding registry to check if the image has been updated. We consider an image to be updated if the digest in the local storage is different than the one of the remote image. If an image must be updated, Podman pulls it down and restarts the container. Note that the restarting sequence relies on systemd. At container-creation time, Podman looks up the "PODMAN_SYSTEMD_UNIT" environment variables and stores it verbatim in the container's label. This variable is now set by all systemd units generated by `podman-generate-systemd` and is set to `%n` (i.e., the name of systemd unit starting the container). This data is then being used in the auto-update sequence to instruct systemd (via DBUS) to restart the unit and hence to restart the container. Note that this implementation of auto-updates relies on systemd and requires a fully-qualified image reference to be used to create the container. This enforcement is necessary to know which image to actually check and pull. If we used an image ID, we would not know which image to check/pull anymore.
