When running tests from my IDE, it compiles the tests before running,
then executes the compiled binary to run the tests. Cobra doesn't like that,
because in that situation os.Args is taken as argument for the command that's
executed. The command that's tested now sees the `test-` flags as arguments
(`-test.v -test.run ..`), which causes various tests to fail ("Command XYZ
does not accept arguments").
# compile the tests:
go test -c -o foo.test
# execute the test:
./foo.test -test.v -test.run TestFoo
=== RUN TestFoo
Error: "foo" accepts no arguments.

This test was added in [moby@b2551c6] as part of a larger PR that implemented
unit tests in various packages. In this specific test, it looks like the
`imageSaveFunc` that's defined in the test-table was forgotten to be wired
up, causing all tests to effectively be skipped.
This patch wires up the function so that it's used in the test.

Add a utility for completing platform strings.
Platforms offers completion for platform-strings. It provides a non-exhaustive
list of platforms to be used for completion. Platform-strings are based on
[runtime.GOOS] and [runtime.GOARCH], but with (optional) variants added. A
list of recognised os/arch combinations from the Go runtime can be obtained
through "go tool dist list".
Some noteworthy exclusions from this list:
- arm64 images ("windows/arm64", "windows/arm64/v8") do not yet exist for windows.
- we don't (yet) include `os-variant` for completion (as can be used for Windows images)
- we don't (yet) include platforms for which we don't build binaries, such as
BSD platforms (freebsd, netbsd, openbsd), android, macOS (darwin).
- we currently exclude architectures that may have unofficial builds,
but don't have wide adoption (and no support), such as loong64, mipsXXX,
ppc64 (non-le) to prevent confusion.

Move the code for parsing key-value files, such as used for
env-files and label-files to a separate package. This allows
other projects (such as compose) to use the same parsing
logic, but provide custom lookup functions for their situation
(which is slightly different).
The new package provides utilities for parsing key-value files
for either a file or an io.Reader. Most tests for EnvFile were
now testing functionality that's already tested in the new package,
so were (re)moved.

We used a hard-coded list of capabilities that we copied from containerd,
but the new "capability" package allows use to have a maintained list
of capabilities.
There's likely still some improvements to be made;
First of all, the capability package could provide a function to get the list
of strings.
On the completion-side, we need to consider what format is most convenient;
currently we use the canonical name (uppercase and "CAP_" prefix), however,
tab-completion is case-sensitive by default, so requires the user to type
uppercase letters to filter the list of options.
Bash completion provides a `completion-ignore-case on` option to make completion
case-insensitive (https://askubuntu.com/a/87066), but it looks to be a global
option; the current cobra.CompletionOptions also don't provide this as an option
to be used in the generated completion-script.
Fish completion has `smartcase` (by default?) which matches any case if
all of the input is lowercase.
Zsh does not have a dedicated option, but allows setting matching-rules
(see https://superuser.com/a/1092328).

The `Commit` type was introduced in 2790ac68b3,
to assist triaging issues that were reported with an incorrect version of
runc or containerd. At the time, both `runc` and `containerd` were not yet
stable, and had to be built from a specific commit to guarantee compatibility.
We encountered various situations where unexpected (and incompatible) versions
of those binaries were packaged, resulting in hard to trace bug-reports.
For those situations, a "expected" version was set at compile time, to
indicate if the version installed was different from the expected version;
docker info
...
runc version: a592beb5bc4c4092b1b1bac971afed27687340c5 (expected: 69663f0bd4b60df09991c08812a60108003fa340)
Both `runc` and `containerd` are stable now, and docker 19.03 and up set the
expected version to the actual version since c65f0bd13c
and 23.0 did the same for the `init` binary b585c64e2b,
to prevent the CLI from reporting "unexpected version".
In short; the `Expected` fields no longer serves a real purpose, so we should
no longer print it.

Running `docker login` in a non-interactive environment sometimes errors

It's worth calling out a separate scenario – if there are previous,
valid credentials, then running `docker login` with no username or
password provided will use the previously stored credentials, and not
error out.
```console
cat ~/.docker/config.json
{
"auths": {
"https://index.docker.io/v1/": {
"auth": "xxxxxxxxxxx"
}
}
}
⭑ docker login 0>/dev/null

```
This commit also applies the same non-interactive handling logic to the
new web-based login flow, which means that now, if there are no prior
credentials stored and a user runs `docker login`, instead of initiating
the new web-based login flow, an error is returned.

Previously, if while polling for oauth device-code login results a user
suspended the process (such as with CTRL-Z) and then restored it with
`fg`, an error might occur in the form of:
```
failed waiting for authentication: You are polling faster than the specified interval of 5 seconds.
```
This is due to our use of a `time.Ticker` here - if no receiver drains
the ticker channel (and timers/tickers use a buffered channel behind the
scenes), more than one tick will pile up, causing the program to "tick"
twice, in fast succession, after it is resumed.
The new implementation replaces the `time.Ticker` with a `time.Timer`
(`time.Ticker` is just a nice wrapper) and introduces a helper function
`resetTimer` to ensure that before every `select`, the timer is stopped
and it's channel is drained.

Normalization/converting the registry address to just a hostname happens
inside of `command.GetDefaultAuthConfig`. Use this value for the rest of
the login flow/storage.
Signed-off-by: Laura Brehm <laurabrehm@hey.com>
This reverts commit e6624676e0.
Since e6624676e0, during login, we started
normalizing `registry-1.docker.io` to `index.docker.io`. This means that
if a user logs in with `docker login -u [username]
registry-1.docker.io`, the user's credentials get stored in
credhelpers/config.json under `https://index.docker.io/v1/`.
However, while the registry code normalizes an image reference without
registry (`docker pull alpine:latest`) and image references explicitly for
`index.docker.io` (`docker pull index.docker.io/library/alpine:latest`)
to the official index server (`https://index.docker.io/v1/`), and
fetches credentials for that auth key, it does not normalize
`registry-1.docker.io`, which means pulling explicitly from there
(`docker pull registry-1.docker.io/alpine:latest`) will not use
credentials stored under `https://index.docker.io/v1/`.
As such, until changes are made to the registry/pull/push code to
normalize `registry-1.docker.io` to `https://index.docker.io/v1/`, we
should not normalize this during login.

On `docker ps`, port bindings with an IPv6 HostIP should have their

RFC 3986 (Section 3.2.2) stipulates that IPv6 addresses should be
enclosed within square brackets. This RFC is only about URIs. However,
doing so here helps user identifier what's part of the IP address and
what's the port. It also makes it easier to copy/paste that

This commit adds support for the oauth [device-code](https://auth0.com/docs/get-started/authentication-and-authorization-flow/device-authorization-flow)
login flow when authenticating against the official registry.
This is achieved by adding `cli/internal/oauth`, which contains code to manage
interacting with the Docker OAuth tenant (`login.docker.com`), including launching
the device-code flow, refreshing access using the refresh-token, and logging out.
The `OAuthManager` introduced here is also made available through the `command.Cli`
interface method `OAuthManager()`.
In order to maintain compatibility with any clients manually accessing
the credentials through `~/.docker/config.json` or via credential
helpers, the added `OAuthManager` uses the retrieved access token to
automatically generate a PAT with Hub, and store that in the
credentials.

This test was just incorrect (and testing incorrect

context, but this was incorrect (and was fixed in
991b1303da - which was when this test
started failing).
However, since this test assertion was happening inside of a goroutine,
it would sometimes pass if this assertion didn't get to run before the
test suite terminated. It was flaky because sometimes this assertion
inside the goroutine did get to execute, but after the test finished
execution, which is a big no-no.
As an aside, assertions inside goroutines are generally bad, and `govet`
even has a linter for this (but it only catches `t.Fatal` and `t.FailNow`
calls and not `assert.Xx`.

In 3f0d90a2a9 we introduced a global

Due to that change, and how we use this context during `docker attach`,
we started to return the context cancelation error when a user signals
the running `docker attach`.
Since this is the intended behavior, we shouldn't return an error, so
this commit adds checks to ignore this specific error in this case.

This environment variable allows for setting additional headers
to be sent by the client. Headers set through this environment
variable are added to headers set through the config-file (through

This environment variable can be used in situations where headers
must be set for a specific invocation of the CLI, but should not
be set by default, and therefore cannot be set in the config-file.
WARNING: If both config and environment-variable are set, the environment
variable currently overrides all headers set in the configuration file.
This behavior may change in a future update, as we are considering the

The `reportError` utility was present because cli.StatusError would print
the error decorated with `Status: <error-message>, Code: <exit-code>`.
That was not desirable in many cases as it would mess-up the output. To
prevent this, the CLI had code to check for an empty `Status` (error message)
in which case the error would be "ignored" (and only used for the exit-status),
and the `reportError` utility would be used to manually print a custom error
message before returning the error.
Now that bca2090061 fixed the output format
of `cli.StatusError`, and 3dd6fc365d and
350a0b68a9 no longer discard these error,
we can get rid of this utility, and just set the error-message for
the status-error.
This patch:
- Introduces a `withHelp` which takes care of decorating errors with
a "Run --help" hint for the user.
- Introduces a `toStatusError` utility that detects certain errors in
the container to assign a corresponding exit-code (these error-codes
can be used to distinguish "client" errors from "container" errors).
- Removes the `reportError` utility, and removes code that manually
printed errors before returning.
Behavior is mostly unmodified, with the exception of some slight reformatting
of the errors:
- `withHelp` adds a `docker:` prefix to the error, to indicate the error
is produced by the `docker` command. This prefix was already present
in most cases.
- The "--help" hint is slightly updated ("Run 'docker run --help' for
more information" instead of "See 'docker run --help'"), to make it
more clear that it's a "call to action".
- An empty is added before the "--help" hint to separate it better from
the error-message.

When trying to use an invalid flag, the CLI currently prints the a short
error message, instructions to use the `--help` flag to learn about the
correct usage, followed by the command's usage output.
While this is a common convention, and may have been a nice gesture when
docker was still young and only had a few commands and options ("you did
something wrong, but here's an overview of what you can use"), that's no
longer the case, and many commands have a _very_ long output.
The result of this is that the error message, which is the relevant
information in this case - "You mis-typed something" - is lost in the
output, and hard to find (sometimes even requiring scrolling back).
The output is also confusing, because it _looks_ like something ran
successfully (most of the output is not about the error!).
Even further; the suggested resolution (try `--help` to see the correct
options) is rather redundant, because running teh command with `--help`
produces _exactly_ the same output as was just showh, baring the error
message. As a fun fact, due to the usage output being printed, the
output even contains not one, but _two_ "call to actions";
- `See 'docker volume --help'.` (under the erro message)
- `Run 'docker volume COMMAND --help' for more information on a command.`
(under the usage output)
In short; the output is too verbose, confusing, and doesn't provide
a good UX. Let's reduce the output produced so that the focus is on the
important information.
This patch:
- Changes the usage to the short-usage.
- Prefixes the error message with the binary / root-command name
(usually `docker:`) to be consistent with `unknon command`, and helps
to distinguish where the message originated from (the `docker` CLI in
this case).
- Adds an empty line between the error-message and the "call to action"
(`Run 'docker volume --help' ...` in the example below). This helps
separating the error message ("unkown flag") from the call-to-action.
