The biggest obstacle here was cleanup - we needed a way to remove
detached exec sessions after they exited, but there's no way to
tell if an exec session will be attached or detached when it's
created, and that's when we must add the exit command that would
do the removal. The solution was adding a delay to the exit
command (5 minutes), which gives sufficient time for attached
exec sessions to retrieve the exit code of the session after it
exits, but still guarantees that they will be removed, even for
detached sessions. This requires Conmon 2.0.17, which has the new
`--exit-delay` flag.
As part of the exit command rework, we can drop the hack we were
using to clean up exec sessions (remove them as part of inspect).
This is a lot cleaner, and I'm a lot happier about it.
Otherwise, this is just plumbing - we need a bindings call for
detached exec, and that needed to be added to the tunnel mode
backend for entities.

This adds bindings for starting exec sessions, and then uses them
to wire up detached exec. Code is heavily based on Attach code
for containers, slightly modified to handle exec sessions.
Bindings are presently attached-only, detached is pending on a
Conmon update landing in CI. I'll probably get to that next.

* Support the `X-Registry-Auth` http-request header.
* The content of the header is a base64 encoded JSON payload which can
either be a single auth config or a map of auth configs (user+pw or
token) with the corresponding registries being the keys. Vanilla
Docker, projectatomic Docker and the bindings are transparantly
supported.
* Add a hidden `--registries-conf` flag. Buildah exposes the same
flag, mostly for testing purposes.
* Do all credential parsing in the client (i.e., `cmd/podman`) pass
the username and password in the backend instead of unparsed
credentials.
* Add a `pkg/auth` which handles most of the heavy lifting.
* Go through the authentication-handling code of most commands, bindings
and endpoints. Migrate them to the new code and fix issues as seen.
A final evaluation and more tests is still required *after* this
change.
* The manifest-push endpoint is missing certain parameters and should
use the ABI function instead. Adding auth-support isn't really
possible without these parts working.
* The container commands and endpoints (i.e., create and run) have not
been changed yet. The APIs don't yet account for the authfile.
* Add authentication tests to `pkg/bindings`.

this is a very basic implementation of build. some of the more advanced options need to be included still as well. i think the endpoints for compat and libpod will have to split given buildahs more advanced set of options. that should probably be done by someone more experienced with build internals.

* Update blang/semver to allow ParseTolerant() support
* Provide helper functions for API handlers to obtain client's 'version'
path variable focused on API endpoint tree: libpod vs. compat
* Introduce new errors:
* version not given in path, endpoints may determine if this is a hard
error (ErrVersionNotGiven)
* given version not supported (ErrVersionNotSupported), only a soft
error if the handler is going to hijack the connection
* Added unit tests for version parsing
* bindings check version on connect:
* client <= Server API version connection is continued
* client >= Server API version connection fails

for the remote client, add the ability to attach to a container, start a container, and run a container.
Signed-off-by: Brent Baude <bbaude@redhat.com>
The usual flow for exec is going to be:
- Create exec session
- Start and attach to exec session
- Exec session exits, attach session terminates
- Client does an exec inspect to pick up exit code
The safest point to remove the exec session, without doing any
database changes to track stale sessions, is to remove during the
last part of this - the single inspect after the exec session
exits.
This is definitely different from Docker (which would retain the
exec session for up to 10 minutes after it exits, where we will
immediately discard) but should be close enough to be not
noticeable in regular usage.

Register system prune route, handler to support system prune,
Adds testcase to validate the system prune flow.
Signed-off-by: Sujil02 <sushah@redhat.com>
While this commit was initially meant to fix#5847, it has turned into a
bigger refactoring which I did not manage to break into smaller pieces:
* Fix#5847 by refactoring the image-removal logic.
* Make the api handler for image-removal use the ABI code. This way,
both (i.e., ABI and Tunnel) end up using the same code. Achieving
this code share required to move some code around to prevent circular
dependencies.
* Everything in pkg/api (excluding pkg/api/types) must now only be
accessed from code using `ABISupport`.
* Avoid imports from entities on handlers to prevent circular
dependencies.
* Move `podman system service` logic into `cmd` to prevent circular
dependencies - it depends on pkg/api.
* Also remove the build header from infra/abi files. It will otherwise
confuse swagger and other tools; errors we cannot fix as go doesn't
expose a build-tag env variable.

A few major fixes here:
- Support for attaching to Configured containers, to match Docker
behavior.
- Support for stream parameter has been improved (we now properly
handle cases where it is not set).
- Initial support for logs parameter has been added.
- Setting attach streams when the container has a terminal is now
supported.
- Errors are properly reported once the hijack has begun.

Implement the `podman {container} logs` for the v2 client. The remote
client does not yet support it. There's some more work needed for the

The remote parts will be tackled in a future change.

* Implement `podman-push` and `podman-image-push` for the podmanV2
client.
* Tests for `pkg/bindings` are not possible at the time of writing as we
don't have a local registry running.
* Implement `/images/{name}/push` compat endpoint. Tests are not
implemented for this v2 endpoint. It has been tested manually.
General note: The auth config extraction from the http header is not
implement for push. Since it's not yet supported for other endpoints
either, I deferred it to future work.
