Formatting stats runs in a loop to refresh the stats for each container. This
patch makes some small performance improvments by reducing the use of Sprintf
in favor of concatenating strings, and using strconv directly where possible.

This adds a new annotation to commands that are known to be frequently
used, and allows setting a custom weight/order for these commands to
influence in what order they appear in the --help output.
I'm not entirely happy with the implementation (we could at least use
some helpers for this, and/or make it more generic to group commands
in output), but it could be a start.
For now, limiting this to only be used for the top-level --help, but
we can expand this to subcommands as well if we think it makes sense
to highlight "common" / "commonly used" commands.

The DefaultStopSignal const has been deprecated, because the daemon already
handles a default value. The current code did not actually send the default
value unless the flag was set, which also made the flag description incorrect,
because in that case, the _daemon's_ default would be used, which could
potentially be different as was specified here.
This patch removes the default value from the flag, leaving it to the daemon
to set a default.

We refactorted `ForwardAllSignals` so it blocks but did not update the
call in `start` to call it in a goroutine.
Signed-off-by: Brian Goff <cpuguy83@gmail.com>
Commit fff164c22e modified ForwardAllSignals to
take `SIGURG` signals into account, which can be generated by the Go runtime
on Go 1.14 and up as an interrupt to support pre-emptable system calls on Linux.
With the updated code, the signal (`s`) would sometimes be `nil`, causing spurious
(but otherwise harmless) warnings to be printed;
Unsupported signal: <nil>. Discarding.
To debug this issue, I patched v20.10.4 to handle `nil`, and added a debug line
to print the signal in all cases;
```patch

instead pass it "all signals _minus_ the signals we don't want forwarded":

When using `docker rm` / `docker container rm` with the `-f` / `--force` option, attempts to remove non-existing containers should print a warning, but should return a zero exit code ("successful").
Currently, a non-zero exit code is returned, marking the removal as "failed";
$ docker rm -fv 798c9471b695
Error: No such container: 798c9471b695
$ echo $?
1
The command should match the behavior of `rm` / `rm -f`, with the exception that
a warning is printed (instead of silently ignored):
Running `rm` with `-f` silences output and returns a zero exit code:
touch some-file && rm -f no-such-file some-file; echo exit code: $?; ls -la
# exit code: 0
# total 0
# drwxr-xr-x 2 sebastiaan staff 64 Aug 14 12:17 .
# drwxr-xr-x 199 sebastiaan staff 6368 Aug 14 12:13 ..
mkdir some-directory && rm -rf no-such-directory some-directory; echo exit code: $?; ls -la
# exit code: 0
# total 0
# drwxr-xr-x 2 sebastiaan staff 64 Aug 14 12:17 .
# drwxr-xr-x 199 sebastiaan staff 6368 Aug 14 12:13 ..
Note that other reasons for a delete to fail should still result in a non-zero
exit code, matching the behavior of `rm`. For instance, in the example below,
the `rm` failed because directories can only be removed if the `-r` option is used;
touch some-file && mkdir some-directory && rm -f some-directory no-such-file some-file; echo exit code: $?; ls -la
# rm: some-directory: is a directory
# exit code: 1
# total 0
# drwxr-xr-x 3 sebastiaan staff 96 Aug 14 14:15 .
# drwxr-xr-x 199 sebastiaan staff 6368 Aug 14 12:13 ..
# drwxr-xr-x 2 sebastiaan staff 64 Aug 14 14:15 some-directory
This patch updates the `docker rm` / `docker container rm` command to not produce
an error when attempting to remove a missing containers, and instead only print
the error, but return a zero (0) exit code.

Before this patch, using a template that used templating functions (such as
`lower` or `json`) caused the command to fail in the pre-processor step (in
`buildContainerListOptions`):
docker ps --format='{{upper .Names}}'
template: :1:8: executing "" at <.Names>: invalid value; expected string
This problem was due to the pre-processing using a different "context" type than
was used in the actual template, and custom functions to not be defined when
instantiating the Go template.
With this patch, using functions in templates works correctly:
docker ps --format='{{upper .Names}}'

For backward compatibility: if no custom options are provided for the network,
and only a single network is specified, omit the endpoint-configuration
on the client (the daemon will still create it when creating the container)
This fixes an issue on older versions of legacy Swarm, which did not support
`NetworkingConfig.EndpointConfig`.
This was introduced in 5bc09639cc (#1767)

This allows setting the ip/ipv6 address as an option in the

This refactors the way networking options are parsed, and makes the
client able to pass options for multiple networks. Currently, the
daemon does not yet accept multiple networks when creating a container,
and will produce an error.
For backward-compatibility, the following global networking-related
options are associated with the first network (in case multiple
networks are set);
- `--ip`
- `--ip6`
- `--link`
- `--link-local-ip`
- `--network-alias`
Not all of these options are supported yet in the advanced notation,
but for options that are supported, setting both the per-network option
and the global option will produce a "conflicting options" error.

The commit contains cli changes to support driver options for a network in
docker run and docker network connect cli's. The driver-opt, aliases is now
supported in the form of csv as per network option in service commands in
swarm mode since docker/cli#62 . This commit extends this support to docker
run command as well.
For docker connect command `--driver-opt` is added to pass driver specific
options for the network the container is connecting to.

This adds validation to `docker container run` / `docker container create`;
Validation of labels provided through flags was removed in 31dc5c0a9a,
after the validation was changed to fix labels without values, and to prevent
labels from being expanded with environment variables in 2b17f4c8a8
However, now empty label names from _files_ (`--label-file`) followed different
validation rules than labels passed through `--label`.
This patch adds back minimal validation for labels passed through the command-line
Before this patch:
```bash
docker container create \
--name label \
--label==with-leading-equal-sign \
--label=without-value \
--label=somelabel=somevalue \
--label " = " \
--label=with-quotes-in-value='{"foo"}' \
--label='with"quotes"in-key=test' \
busybox
docker container inspect --format '{{json .Config.Labels}}' label
```
```json
{
"": "with-leading-equal-sign",
" ": " ",
"somelabel": "somevalue",
"with\"quotes\"in-key": "test",
"with-quotes-in-value": "{\"foo\"}",
"without-value": ""
}
```
After this patch:
```bash
docker container create \
--name label \
--label==with-leading-equal-sign \
--label=without-value \
--label=somelabel=somevalue \
--label " = " \
--label=with-quotes-in-value='{"foo"}' \
--label='with"quotes"in-key=test' \
busybox
invalid argument "=with-leading-equal-sign" for "-l, --label" flag: invalid label format: "=with-leading-equal-sign"

Previously, these errors were only printed when using `docker run`, but were
omitted when using `docker container create` and `docker container start`
separately.
Given that these warnings apply to both situations, this patch moves generation
of these warnings to `docker container create` (which is also called by
`docker run`)

A while ago, Docker split the "Domainname" field out from the "Hostname"
field for the container configuration. There was no real user-visible
change associated with this (and under the hood "Domainname" was mostly
left unused from the command-line point of view). We now add this flag
in order to match other proposed changes to allow for setting the NIS
domainname of a container.
This also includes a fix for the --hostname parsing tests (they would
not error out if only one of .Hostname and .Domainname were incorrectly
set -- which is not correct).

- make it possible to extract the formatter implementation from the
"common" code, that way, the formatter package stays small
- extract some formatter into their own packages
This is essentially moving the "formatter" implementation of each type
in their respective packages. The *main* reason to do that, is to be
able to depend on `cli/command/formatter` without depending of the
implementation detail of the formatter. As of now, depending on
`cli/command/formatter` means we depend on `docker/docker/api/types`,
`docker/licensing`, … — that should not be the case. `formatter`
should hold the common code (or helpers) to easily create formatter,
not all formatter implementations.

Commit 2b17f4c8a8 fixed the way empty labels
are taken into account (i.e. not interpolated from environment variable),
but it created a regression.

always been possible to pass an empty label via the cli (`docker run --label foo`).
This fixes that by not validating the label flag.

`--label-file` has the exact same behavior as `--env-file`, meaning any
placeholder (i.e. a simple key, no `=` sign, no value), it will get the
value from the environment variable.
For `--label-file` it should just add an empty label.

This is necessary in order to avoid execId leaks in the case where a
`docker exec -it` is run without a terminal available for the client.
You can reproduce this issue by running the following command many
times.
% nohup docker exec -it some_container true
The container `some_container` will have execIDs that will never
normally be cleaned up (because the client died before they were
started).
In addition, this patch adds a docker-inspect step to ensure that we
give "container does not exist" errors consistently.
