Go maintainers started to unconditionally update the minimum go version
for golang.org/x/ dependencies to go1.23, which means that we'll no longer
be able to support any version below that when updating those dependencies;

This updates our minimum version to go1.23, as we won't be able to maintain

The errors.Wrap and errors.Wrapf functions gracefully handle nil-errors.
This allows them to be used unconditionally regardless if an error
was produced.
While this can be convenient, it can also be err-prone, as replacing
these with stdlib errors means they unconditionally produce an error.
This patch replaces code uses of errors.Wrap to be gated by a check
for nil-errors to future-proof our code.

This is a follow-up to 55e404e7a8, which
removed some warnings related to these fields.
These fields in the /info response were used to warn users if netfiltering
was not enabled on the host when the daemon started. Starting with
[moby@db25b0d], detecting whether netfiltering is enabled now
[happens when needed][1], making the state that's detected at startup
irrelevant.
These fields will therefore be deprecated in future, but we can start
removing their use in tests.

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.

This error didn't do a great job at formatting. If a StatusError was
produced without a Status message, it would print a very non-informative
error, with information missing.
Let's update the output:
- If a status-message is provided; print just that (after all the
status code is something that can be found from the shell, e.g.
through `echo $?` in Bash).
- If no status-message is provided: print a message more similar to
Go's `exec.ExecError`, which uses `os.rocessState.String()` (see [1]).
Before this patch, an error without custom status would print:
Status: , Code: 2
After this patch:
exit status 2
In situations where a custom error-message is provided, the error-message
is print as-is, whereas before this patch, the message got combined with
the `Status:` and `Code:`, which resulted in some odd output.
Before this patch:
docker volume --no-such-flag
Status: unknown flag: --no-such-flag
See 'docker volume --help'.
Usage: docker volume COMMAND

Commands:
create Create a volume
inspect Display detailed information on one or more volumes

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).
