* utils: use podman-pause-$RANDOM.scope nameGiuseppe Scrivano2021-11-17
| | | | | | | | | | | | | | | we try hard to re-use the existing podman-pause.scope name when it already exists, causing any sort of race errors when the already existing scope is terminating. There is no such a requirement though, so just try with a random name. Closes: https://github.com/containers/podman/issues/12065 [NO NEW TESTS NEEDED] it fixes a race in the CI Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>
* runtime: change PID existence checkGiuseppe Scrivano2021-10-28
| | | | | | | | | | | | | | | commit 6b3b0a17c625bdf71b0ec8b783b288886d8e48d7 introduced a check for the PID file before attempting to move the PID to a new scope. This is still vulnerable to TOCTOU race condition though, since the PID file or the PID can be removed/killed after the check was successful but before it was used. Closes: https://github.com/containers/podman/issues/12065 [NO NEW TESTS NEEDED] it fixes a CI flake Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>

* utils: raise warning only on cgroupv2Giuseppe Scrivano2021-09-20
| | | | | | | | | | | if it is not running on cgroup v2, print only a debug message since rootless users cannot create the cgroup. commit 9c1e27fdd536f6026efe3da4360755a3e9135ca8 introduced the regression. [NO TESTS NEEDED] Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>

* Ensure libpod/define does not include libpod/imageMatthew Heon2020-07-31
| | | | | | | | | | | | | The define package under Libpod is intended to be an extremely minimal package, including constants and very little else. However, as a result of some legacy code, it was dragging in all of libpod/image (and, less significantly, the util package). Fortunately, this was just to ensure that error constants were not duplicating, and there's nothing preventing us from importing in the other direction and keeping libpod/define free of dependencies.

* Fix manual detach from containers to not wait for exitMatthew Heon2019-02-12
| | | | | | | | | | | | | | | | | | | | | | | | | At present, when manually detaching from an attached container (using the detach hotkeys, default C-p C-q), Podman will still wait for the container to exit to obtain its exit code (so we can set Podman's exit code to match). This is correct in the case where attach finished because the container exited, but very wrong for the manual detach case. As a result of this, we can no longer guarantee that the cleanup and --rm functions will fire at the end of 'podman run' - we may be exiting before we get that far. Cleanup is easy enough - we swap to unconditionally using the cleanup processes we've used for detached and rootless containers all along. To duplicate --rm we need to also teach 'podman cleanup' to optionally remove containers instead of cleaning them up. (There is an argument for just using 'podman rm' instead of 'podman cleanup --rm', but cleanup does have different semantics given that we only ever expect it to run when the container has just exited. I think it might be useful to keep the two separate for things like 'podman events'...) Signed-off-by: Matthew Heon <mheon@redhat.com>
* Add container runlabel commandbaude2018-09-28
| | | | | | | | | | | | | Execute the command as described by a container image. The value of the label is processed into a command by: 1. Ensuring the first argument of the command is podman. 2. Substituting any variables with those defined by the environment or otherwise. If no label exists in the container image, nothing is done. podman container runlabel LABEL IMAGE extra_args Signed-off-by: baude <bbaude@redhat.com>
