* Fix --tail log on restart problemDaniel J Walsh2022-04-13
| | | | | | | | | | | | | --tail=1 is not working f you restart a container with journald logging. We see the exit status and then call into the logging a second time causing all of the logs to print. Removing the tail log on exited seems to fix the problem.

| * journald logs: keep reading until the journal's endNalin Dahyabhai2021-11-15
| | | | | | | | | | | | | | | | | | | | | | When reading logs from the journal, keep going after the container exits, in case it gets restarted. Events logged to the journal via the normal paths don't include CONTAINER_ID_FULL, so don't bother adding it to the "history" event we use to force at least one entry for the container to show up in the log.

* Fix a few problems in 'podman logs --tail' with journald driverHironori Shiina2021-10-26
| | | | | | | | | | | | | | | | | The following problems regarding `logs --tail` with the journald log driver are fixed: - One more line than a specified value is displayed. - '--tail 0' displays all lines while the other log drivers displays nothing. - Partial lines are not considered. - If the journald events backend is used and a container has exited, nothing is displayed. Integration tests that should have detected the bugs are also fixed. The tests are executed with json-file log driver three times without this fix.

* Use exponential backoff when waiting for a journal entryNalin Dahyabhai2021-10-18

* libpod/Container.readFromJournal(): don't skip the first entryNalin Dahyabhai2021-08-23
| | | | | | | | | | | | | | | When reading log entries from the journal, don't skip past the first matching entry after we've positioned the cursor at it. Make the first blank-line entry that we logged so that the container would always have at least one log entry for us to find (until it gets vacuumed out, at least) a fake history entry, so that `logs` doesn't pass it on for display. CI already has tests that exercise journal-based logging, so [NO TESTS NEEDED] Signed-off-by: Nalin Dahyabhai <nalin@redhat.com>

* journald logger: fix race conditionValentin Rothberg2021-05-26
| | | | | | | | | | | | | | | | | | | | | | | Fix a race in journald driver. Following the logs implies streaming until the container is dead. Streaming happened in one goroutine, waiting for the container to exit/die and signaling that event happened in another goroutine. The nature of having two goroutines running simultaneously is pretty much the core of the race condition. When the streaming goroutines received the signal that the container has exitted, the routine may not have read and written all of the container's logs. Fix this race by reading both, the logs and the events, of the container and stop streaming when the died/exited event has been read. The died event is guaranteed to be after all logs in the journal which guarantees not only consistencty but also a deterministic behavior. Note that the journald log driver now requires the journald event backend to be set. Fixes: #10323 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
* podman image tree: restore previous behaviorValentin Rothberg2021-05-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The initial version of libimage changed the order of layers which has now been restored to remain backwards compatible. Further changes: * Fix a bug in the journald logging which requires to strip trailing new lines from the message. The system tests did not pass due to empty new lines. Triggered by changing the default logger to journald in containers/common. * Fix another bug in the journald logging which embedded the container ID inside the message rather than the specifid field. That surfaced in a preceeding whitespace of each log line which broke the system tests. * Alter the system tests to make sure that the k8s-file and the journald logging drivers are executed. * A number of e2e tests have been changed to force the k8s-file driver to make them pass when running inside a root container. * Increase the timeout in a kill test which seems to take longer now. Reasons are unknown. Tests passed earlier and no signal-related changes happend. It may be CI VM flake since some system tests but other flaked. Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

| | | | | | | | | Add a `context.Context` to the log APIs to allow for cancelling streaming (e.g., via `podman logs -f`).

* 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.
