This test was just incorrect (and testing incorrect
behavior): it was checking that `docker run` exited with a `context
canceled` error after signalling the CLI/cancelling the command's
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`.

Such as with `docker run`, if a user CTRL-Cs while attached to a
container, we should forward the signal and wait for the exit from
`ContainerWait`, instead of just returning.

In 3f0d90a2a9 we introduced a global
signal handler and made sure all the contexts passed into command
execution get (appropriately) cancelled when we get a SIGINT.
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.
Also adds a regression test.

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.

"docker run" and "docker create" are mostly identical, so we can copy
the same completion functions,
We could possibly create a utility for this (similar to `addFlags()` which
configures both commands with the flags they share). I considered combining
his with `addFlags()`, but that utility is also used in various tests, in
which we don't need this feature, so keeping that for a future exercise.

EnvVarNames offers completion for environment-variable names. This
completion can be used for "--env" and "--build-arg" flags, which
allow obtaining the value of the given environment-variable if present
in the local environment, so we only should complete the names of the
environment variables, and not their value. This also prevents the
completion script from printing values of environment variables
containing sensitive values.
For example;
export MY_VAR=hello
docker run --rm --env MY_VAR alpine printenv MY_VAR
hello

This makes a quick pass through our tests;
Discard output/err
----------------------------------------------
Many tests were testing for error-conditions, but didn't discard output.
This produced a lot of noise when running the tests, and made it hard
to discover if there were actual failures, or if the output was expected.
For example:
=== RUN TestConfigCreateErrors
Error: "create" requires exactly 2 arguments.
See 'create --help'.
Usage: create [OPTIONS] CONFIG file|- [flags]
Create a config from a file or STDIN
Error: "create" requires exactly 2 arguments.
See 'create --help'.
Usage: create [OPTIONS] CONFIG file|- [flags]
Create a config from a file or STDIN
Error: error creating config
--- PASS: TestConfigCreateErrors (0.00s)
And after discarding output:
=== RUN TestConfigCreateErrors
--- PASS: TestConfigCreateErrors (0.00s)
Use sub-tests where possible
----------------------------------------------
Some tests were already set-up to use test-tables, and even had a usable
name (or in some cases "error" to check for). Change them to actual sub-
tests. Same test as above, but now with sub-tests and output discarded:
=== RUN TestConfigCreateErrors
=== RUN TestConfigCreateErrors/requires_exactly_2_arguments
=== RUN TestConfigCreateErrors/requires_exactly_2_arguments#01
=== RUN TestConfigCreateErrors/error_creating_config
--- PASS: TestConfigCreateErrors (0.00s)
--- PASS: TestConfigCreateErrors/requires_exactly_2_arguments (0.00s)
--- PASS: TestConfigCreateErrors/requires_exactly_2_arguments#01 (0.00s)
--- PASS: TestConfigCreateErrors/error_creating_config (0.00s)
PASS
It's not perfect in all cases (in the above, there's duplicate "expected"
errors, but Go conveniently adds "#01" for the duplicate). There's probably
also various tests I missed that could still use the same changes applied;
we can improve these in follow-ups.
Set cmd.Args to prevent test-failures
----------------------------------------------
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.
The Cobra maintainers ran into the same situation, and for their own
use have added a special case to ignore `os.Args` in these cases;
https://github.com/spf13/cobra/blob/v1.8.1/command.go#L1078-L1083
args := c.args
// Workaround FAIL with "go test -v" or "cobra.test -test.v", see #155
if c.args == nil && filepath.Base(os.Args[0]) != "cobra.test" {
args = os.Args[1:]
}
Unfortunately, that exception is too specific (only checks for `cobra.test`),
so doesn't automatically fix the issue for other test-binaries. They did
provide a `cmd.SetArgs()` utility for this purpose
https://github.com/spf13/cobra/blob/v1.8.1/command.go#L276-L280
// SetArgs sets arguments for the command. It is set to os.Args[1:] by default, if desired, can be overridden
// particularly useful when testing.
func (c *Command) SetArgs(a []string) {
c.args = a
}
And the fix is to explicitly set the command's args to an empty slice to
prevent Cobra from falling back to using `os.Args[1:]` as arguments.
cmd := newSomeThingCommand()
cmd.SetArgs([]string{})
Some tests already take this issue into account, and I updated some tests
for this, but there's likely many other ones that can use the same treatment.
Perhaps the Cobra maintainers would accept a contribution to make their
condition less specific and to look for binaries ending with a `.test`
suffix (which is what compiled binaries usually are named as).

Docker v23.0 and up allow the daemon to be configured to have seccomp disabled
by default (using the "unconfined" profile as default), and introduced a new
"builtin" profile-name for the default (see [moby@f8795ed364586acd][1] and
[mnoby@ac449d6b5ad29a50][2]).
However, the CLI had no special handling for the "builtin" profile, which
resulted in it trying to load it as a file, which would fail;
docker run -it --rm --security-opt seccomp=builtin busybox
docker: opening seccomp profile (builtin) failed: open builtin: no such file or directory.
See 'docker run --help'.
This patch adds a special case for the "builtin" profile, to allow using the
default profile on daemons with seccomp disabled (unconfined) by default.

The filter option is not currently exposed on the command-line,
but can be added as a flag in future. It will be used by compose
to filter the list of containers to include based on compose
labels.

When running `docker stats` without a list of containers, `runStats` collects
an initial list of containers. If that API call fails, the error is sent to the
`closeChan`, however, `closeChan` is non-buffered, and nothing is reading the
channel until we received the initial list and start collecting stats.
This patch rewrites the code that gets the initial list of containers to
return the error if the API call fails. The `getContainerList` closure is
also removed and inlined to make the logic somewhat easier to read.
Before this patch, the command would hang without producing output;
docker stats
# hangs; no output
With this patch, the error is printed, and the CLI exits:
docker stats
Error response from daemon: some error occurred
echo $?

The monitorContainerEvents and getContainerList closures where only
used when collecting "all" containers, so let's define them in that
branch of the code.
Also move some of the other variables closer to where they're used.
