Nalin Dahyabhai 21f396de6f logs: adjust handling around partial log messages
In libpod/logs.LogLine.Write(), don't write a newline to stdout/stderr
when the log message is only part of a line.

In libpod.ConmonOCIRuntime.HTTPAttach(), don't send a newline over the
HTTP connection when the log message is only part of a line.

In pkg/api/handlers/compat.LogsFromContainer(), don't send a newline
over the HTTP connection when the log message is only part of a line,
and don't make doing so conditional on whether or not the client used
the docker or podman endpoint.

In pkg/domain/infra/tunnel.ContainerEngine.ContainerLogs(), don't add
our own newline to log messages, since they already come through from
the server when they need to.

Valentin Rothberg fe2be7f886 make sure that signal buffers are sufficiently big
Dealing with os.Signal channels seems more like an art than science
since signals may get lost.  os.Notify doesn't block on an unbuffered
channel, so users are expected to know what they're doing or hope for
the best.

In the recent past, I've seen a number of flakes and BZs on non-amd64
architectures where I was under the impression that signals may got
lost, for instance, during stop and exec.

[NO TESTS NEEDED] since this is art.

2021-08-05 13:52:15 +00:00
Valentin Rothberg 30df551bde auto-update: simple rollback
Add support for simple rollbacks during `podman auto-update`.  Rollbacks
are enabled by default.  If a systemd unit cannot be restarted after an
update, the previous image will be retagged and the unit will be
restarted a second time.

Add system tests for rollbacks.  Also fix a bug in the restart sequence;
we have to use the channel to actually know whether the restart was
successful or not.

NOTE: To make rollbacks really useful, users must run their containers
with `--sdnotify=container` such that the containers send the ready
message over the (mounted) socket.  This way, restarting the systemd
units during auto update will block until the message has been received
(or a timeout kicked in).

Brent Baude 3c3fa6fac4 implement init containers in podman
this is the first pass at implementing init containers for podman pods.
init containersare made popular by k8s as a way to run setup for pods
before the pods standard containers run.

unlike k8s, we support two styles of init containers: always and
oneshot.  always means the container stays in the pod and starts
whenever a pod is started.  this does not apply to pods restarting.
oneshot means the container runs onetime when the pod starts and then is
removed.

Support checkpoint/restore with pods
This adds support to checkpoint containers out of pods and restore
container into pods.

It is only possible to restore a container into a pod if it has been
checkpointed out of pod. It is also not possible to restore a non pod
container into a pod.

The main reason this does not work is the PID namespace. If a non pod
container is being restored in a pod with a shared PID namespace, at
least one process in the restored container uses PID 1 which is already
in use by the infrastructure container. If someone tries to restore
container from a pod with a shared PID namespace without a shared PID
namespace it will also fail because the resulting PID namespace will not
have a PID 1.

Additionally a unused const was removed.
Api and cli will fail the request if a 0 or negative value is passed in.

Fix race conditions in rootless cni setup
There was an race condition when calling `GetRootlessCNINetNs()`. It
created the rootless cni directory before it got locked. Therefore
another process could have called cleanup and removed this directory
before it was used resulting in errors. The lockfile got moved into the
XDG_RUNTIME_DIR directory to prevent a panic when the parent dir was
removed by cleanup.

Fixes #10930
Fixes #10922

To make this even more robust `GetRootlessCNINetNs()` will now return
locked. This guarantees that we can run `Do()` after `GetRootlessCNINetNs()`
before another process could have called `Cleanup()` in between.
