* 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>
* add network connect|disconnect compat endpointsbaude2020-11-19
| | | | | | | | | | | 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.

* filter events by labelsbaude2020-10-23
| | | | | | adding the ability to filter evens by the container labels. this requires that container labels be added to the events data being recorded and subsequently read. 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. Fixes: #7022 Signed-off-by: Brent Baude <bbaude@redhat.com>
* 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>

* Add `systemd` build tagSascha Grunert2019-05-13
| | | | | | | | | | | | If the systemd development files are not present on the system which builds podman, then `podman events` will error on runtime creation. Beside this, a warning will be printed when compiling podman. This commit mainly exists because projects which depend on libpod would not need the podman event support and therefore do not need to rely on the systemd headers.

* journald event loggingbaude2019-04-24
| | | | | | | | | add the ability for podman to read and write events to journald instead of just a logfile. This can be controlled in libpod.conf with the `events_logger` attribute of `journald` or `file`. The default will be set to `journald`. Signed-off-by: baude <bbaude@redhat.com>

* Add event logging to libpod, even display to podmanbaude2019-03-11
In lipod, we now log major events that occurr. These events can be displayed using the `podman events` command. Each event contains: * Type (container, image, volume, pod...) * Status (create, rm, stop, kill, ....) * Timestamp in RFC3339Nano format * Name (if applicable) * Image (if applicable) The format of the event and the varlink endpoint are to not be considered stable until cockpit has done its enablement.
