This code was missing a check for the ID field before truncating it to a
shorter length for presentation. This would result in a panic if an event
would either have an empty ID field or a shorter length ID;
panic: runtime error: slice bounds out of range [:12] with length 0

We need to look at this code in general; the truncated ID is passed to
NewStats, which uses the ID to propagate the `Container` field in the
`StatsEntry` struct. which is not used in the default format used by
`docker stats` and, having the same content as the `ID` field on the
same struct, doesn't make it very useful, other than being able to
present it under a `CONTAINER` column (instead of `CONTAINER ID`);
we should consider deprecating it; there may be some subtle things
to look into here; the `Container` field originally held the container
name. This was changed in [moby@ef915fd], which introduced separate
`ID` and `Name` fields, renaming the old `Name` field to container.
Looking at [`Stats.SetStatistics()`] and related code in [stats_helpers.go],
the `Container` field is used as the "canonical" reference for the stats
record; this allows the stats _data_ to be refreshed when a new stats
sample arrives for the same container (also see [moby@929a77b], which
moved locking to the `Stats` wrapper struct). This construct allows to
account for intermediate states, where a stats sample was incomplete
or could produce an error; in that case, the reference to the container
for which the stats were sampled is kept to allow removing a container
from the list once the container was removed. We should consider removing
`Container` as a formatting option, and moving the `Container` field to
the outer struct; this makes the outer struct responsible for keeping a
reference to the container, allowing the `StatsEntry` as a whole to be
replaced atomically.
This patch only addresses the panic;
- It changes the logic to preserve the container ID verbatim instead
of truncating. This allows stats samples to be matched against the
`Actor.ID` as-is.
- Truncating the `Container` is moved to the presentation logic;
currently this does not take `--no-trunc` into account to keep
the existing behavior, but we can (should) consider adding this.
- Logging is improved to use structured logs, and an extra check is
added to prevent empty IDs from being added as watcher.

Moves ParseVolume() to a new internal package to remove the dependency
on cli/compose/loader in cli/command/container/opts.go
refactor to keep types isolated
- rename the package to "volumespec" to reuse the name of the package
as part of the name (parsevolume.ParseVolume() -> volumespec.Parse())
- move the related compose types to the internal package as well,
and rename them to be more generic (not associated with "compose");
- ServiceVolumeConfig -> VolumeConfig
- ServiceVolumeBind -> BindOpts
- ServiceVolumeVolume -> VolumeOpts
- ServiceVolumeImage -> ImageOpts
- ServiceVolumeTmpfs -> TmpFsOpts
- ServiceVolumeCluster -> ClusterOpts
- alias the internal types inside cli/compose/types to keep backward
compatibility (for any external consumers); even though the implementation
is internal, Go allows aliasing types to use them externally.

This utility was only used for testing, and to generate a random
suffix for Dockerfiles. As we don't need the same contract as
pkg/stringid.GenerateRandomID() (not allow all-numeric IDs as they
would not be usable for hostnames), we can use a local test-utility,
and local implementation for the random suffix instead.

We were depending on pkg/stringid to truncate IDs for presentation. While
traditionally, we used a fixed length for "truncated" IDs, this is not
a strict requirement (any ID-prefix should work, but conflicts may
happen on shorter IDs).
This patch adds a local `TruncateID()` utility in the formatter package;
it's currently using the same implementation and length as the
`stringid.TruncateID` function, but may diverge in future.

The `AllowOverwriteDirWithFile` option was added when reimplementing the
CLI using the API Client lib in [moby@1b2b91b]. Before that refactor, the
`noOverwriteDirNonDir` query argument [would be set unconditionally][1]
by the CLI, with no options to control the behavior.
It's unclear why the `noOverwriteDirNonDir` was implemented as opt-in (not
opt-out), as overwriting a file with a directory (or vice-versa) would
generally be unexpected behavior.
We're considering making `noOverwriteDirNonDir` unconditional on the daemon
side, and to deprecate the `AllowOverwriteDirWithFile` option. This patch
removes its use, as it was set to the default either way, and there's no
options to configure it from the CLI.

This was introduced in 9b54d860cd,
which added `docker container remove` as alias for `docker container rm`.
However, due to the `NewRmCommand` being used both for adding the top-level
`docker rm` command and for adding the `docker container rm` command, it
also introduced a (hidden) top-level `docker remove` command;
docker remove --help | head -n1
Usage: docker rm [OPTIONS] CONTAINER [CONTAINER...]
The command was not documented, and did not appear in `--help` output,
nor was auto-complete provided;
docker --help | grep remove
docker r<TAB>
rename (Rename a container) rm (Remove one or more containers) run (Create and run a new container from an image)
restart (Restart one or more containers) rmi (Remove one or more images)
This patch adds a dedicated, non-exported `newRemoveCommand` to add sub-
commands for `docker container`, taking a similar approach as was done in
[moby@b993609d5a] for `docker image rm`.
With this patch applied, the hidden command is no longer there, but
the `docker rm`, `docker container rm`, and `docker container remove`
commands stay functional as intended;
docker remove foo
docker: unknown command: docker remove
Run 'docker --help' for more information
docker rm --help | head -n1
Usage: docker rm [OPTIONS] CONTAINER [CONTAINER...]
docker container rm --help | head -n1
Usage: docker container rm [OPTIONS] CONTAINER [CONTAINER...]
docker container remove --help | head -n1
Usage: docker container rm [OPTIONS] CONTAINER [CONTAINER...]

This field was added in [moby@5130fe5d38837302e], which
added it for use as intermediate struct when parsing CLI flags (through
`runconfig.ParseExec`) in [moby@c786a8ee5e9db8f5f].
Commit [moby@9d9dff3d0d9e92adf] rewrote the CLI to use
Cobra, and as part of this introduced a separate `execOptions` type in
`api/client/container`, however the ExecOptions.Detach field was still
used as intermediate field to store the flag's value.
Given that the client doesn't use this field, let's remove its use to
prevent giving the impression that it's used anywhere.
