As I outlined in the design docs this is broken, there are several
data races here because we write to the config files that can be read by
other goroutines in parallel which violates the go memory model and
thus can lead to runtime panics and undefined behavior.
One could fix with a mutex but that would make the whole code base much
more ugly and there is still the risk that something would access this
field without the mutex held.
I am not sure we have any users using this, it never worked for the
storage side and since the service is a not a daemon any user could just
stop and start it again to re-read the files without having to stop
running containers.

Remove user-facing CLI options for CNI network backend:
CLI flags:
- Keep --network-backend global flag as hidden and deprecated for
backward compatibility with cleanup commands from 5.x containers
- Map flag to a throwaway variable (value is ignored)
- Remove shell completion for network backend values
Shell completions:
- Remove AutocompleteNetworkBackend() function
- Remove references to CNI and Netavark type constants
Backward compatibility:
- Remove --rootless-cni flag alias for podman unshare
- Remove SetNormalizeFunc that mapped rootless-cni to rootless-netns
- Update --rootless-netns flag description to mention only netavark
The --network-backend flag remains as a hidden deprecated flag to
prevent failures when upgrading from 5.x where containers may have
cleanup commands that include this flag. The flag is accepted but
ignored. Users can no longer specify CNI as a network backend option.
The --rootless-cni alias is removed; users must use --rootless-netns.

For Podman 6, we still have providers and will continue to have a default provider for each platform. But where a platform has multiple providers, we want users to be able to cross provider boudnaries imposed in Podman 4/5. The key change is to look up virtual machines by name, as before, but to then also iterate all possible providers. As of this PR, init will still only create with the default provider, but a subsequent PR will introdouce an provider override.
I also removed the "--all-providers" command line option on `podman
machine ls` because it no longer makes sense. And I marked the all
provider list test to be skipped.

automatically changed fileperms to the new octal format and I didn't
want that polluting my diffs.
Decision: I thought it best to switch to the new octal format in a dedicated PR.
Action:
- Cursor switched to new octal format for all fileperm ocurrences in Go
source and test files.
- vendor/, docs/ and non-Go files were ignored.
- Reviewed manually.

BuildOrigin is a field that can be set at build time by packagers. This helps us trace how and where the binary was built and installed from, allowing us to see if the issue is due to a specfic installation or a general podman bug. This field shows up in podman version and in podman info when populated. Note that podman info has a new field, Client, that only appears when running podman info using the remote client.
Automatically set the BuildOrigin field when building the macOS pkginstaller to pkginstaller.

One of the problems with the Events() API was that you had to call it in
a new goroutine. This meant the the error returned by it had to be read
back via a second channel. This cuased other bugs in the past but here
the biggest problem is that basic errors such as invalid since/until
options were not directly returned to the caller.
It meant in the API we were not able to write http code 200 quickly
because we always waited for the first event or error from the
channels. This in turn made some clients not happy as they assume the
server hangs on time out if no such events are generated.
To fix this we resturcture the entire event flow. First we spawn the
goroutine inside the eventer Read() function so not all the callers have
to. Then we can return the basic error quickly without the goroutine.
The caller then checks the error like any normal function and the API
can use this one to decide which status code to return.
Second we now return errors/event in one channel then the callers can
decide to ignore or log them which makes it a bit more clear.

When we are activated by systemd the code assumed that we had a valid
URL which was not the case so it failed to parse the URL which causes
the info call to fail all the time.
This fixes two problems first add the schema to the systemd activated
listener URL so it can be parsed correctly but second simply do not
parse it as url as all we care about in the info call is if it is unix
and the file path exists.

The events code makes use of two channels, one for the events and one
for the resulting error. Then in the main file we have a loop reading
from both channels that should exit on first error it gets.
However in case the event channel is closed before the error channel
cotains the error it could caused an early exit as it looked like all
events were done. Commit c46884aa93 fixed that somewhat by checking for
an error in the error channel before exiting. This however was still
racy as it added a default case in the select which means the channel
check is non blocking. Thus the error was not yet send into the channel.
To fix this we should make it a blocking read to wait for the error in
the channel. Also the err != nil check can be removed as we either
return err or nil anyway.
And as last step make sure the error channel is closed, that prevents us
from blocking forever in case the main select already processed the nil
error.

The function that's handing us events will return an error after closing
the channel over which it's sending events, and its caller (in its own
goroutine) will then send that error over another channel.
The logic that started the goroutine is likely to notice that the events
channel is closed before noticing that the error channel has a result
for it to read, so any error that would have been communicated would be
lost.
When we finish reading events, check if the reader returned an error
before telling our caller that there was no error.

thus change it to a string

event struct
3. the error message was not wired into the cli and API

We now no longer write containers.conf, instead system connections and

This is a major rework and I had to change a lot of things to get this
to compile again with my c/common changes.
It is a breaking change for users as connections/farms added before this
commit can now no longer be removed or modified directly. However because
the logic keeps reading from containers.conf the old connections can

Before this, for some special Podman commands (system reset,
system migrate, system renumber), Podman would create a first
Libpod runtime to do initialization and flag parsing, then stop
that runtime and create an entirely new runtime to perform the
actual task. This is an artifact of the pre-Podman 2.0 days, when
there was almost no indirection between Libpod and the CLI, and
we only used one runtime because we didn't need a second runtime
for flag parsing and basic init.
This system was clunky, and apparently, very buggy. When we
migrated to SQLite, some logic was introduced where we'd select a
different database location based on whether or not Libpod's
StaticDir was manually set - which differed between the first
invocation of Libpod and the second. So we'd get a different
database for some commands (like `system reset`) and they would
not be able to see existing containers, meaning they would not
function properly.
The immediate cause is obviously the SQLite behavior, but I'm
certain there's a lot more baggage hiding behind this multiple
Libpod runtime logic, so let's just refactor it out. It doesn't
make sense, and complicates the code. Instead, make Reset,
Renumber, and Migrate methods of the libpod Runtime. For Reset
and Renumber, we can shut the runtime down afterwards to achieve
the desired effect (no valid runtime after). Then pipe all of
them through the ContainerEngine so cmd/podman can access them.
As part of this, remove the SystemEngine part of pkg/domain. This
was supposed to encompass these "special" commands, but every
command in SystemEngine is actually a ContainerEngine command.
Reset, Renumber, Migrate - they all need a full Libpod and access
to all containers. There's no point to a separate engine if it
just wraps Libpod in the exact same way as ContainerEngine. This
consolidation saves us a bit more code and complexity.

It looks like we had some logic for this from #10789 but it does
not appear to have ever worked; we can't pull external containers
out of the DB, so the ContainerRm call failed unconditionally.
Instead, just handle them in Libpod when we're removing images.
We're removing every image, so setting Force when removing images
should get rid of all external containers. It's a little later in
the process than the current (nonfunctional) solution is but I
can't think of a reason why that would be bad.
[NO NEW TESTS NEEDED] We do not currently test `system reset`.
We should probably reevaluate that at some point this year.
