The format had a stray colon and space included. While fixing that, also
updating the error message to clarify the error happened while parsing
the file (not so much "loading" it).

Before this change, the config-file was always updated, even if there
were no changes to save. This could cause issues when the config-file
already had credentials set and was read-only for the current user.
For example, on NixOS, this poses a problem because `config.json` is a
symlink to a write-protected file;
$ readlink ~/.docker/config.json
/home/username/.config/sops-nix/secrets/ghcr_auth
$ readlink -f ~/.docker/config.json
/run/user/1000/secrets.d/28/ghcr_auth
Which causes `docker login` to fail, even if no changes were to be made;
Error saving credentials: rename /home/derek/.docker/config.json2180380217 /home/username/.config/sops-nix/secrets/ghcr_auth: invalid cross-device link
This patch updates the code to only update the config file if changes
were detected. It there's nothing to save, it skips updating the file,
as well as skips printing the warning about credentials being stored
insecurely.
With this patch applied:
$ docker login -u yourname
Password:

The fileStore itself is aware that it's insecure, so we can make it
responsible for printing the warning. It's not "perfect", as we use
`os.Stderr` unconditionally (not `dockerCli.Err()`), but probably won't
make a difference in _most_ cases.

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).

This will return the ServerAddress property when using the NativeStore.
This happens when you use docker credential helpers, not the credential
store.
The reason this fix is needed is because it needs to be propagated
properly down towards `moby/moby` project in the following logic:
```golang
func authorizationCredsFromAuthConfig(authConfig registrytypes.AuthConfig) docker.AuthorizerOpt {
cfgHost := registry.ConvertToHostname(authConfig.ServerAddress)
if cfgHost == "" || cfgHost == registry.IndexHostname {
cfgHost = registry.DefaultRegistryHost
}
return docker.WithAuthCreds(func(host string) (string, string, error) {
if cfgHost != host {
logrus.WithFields(logrus.Fields{
"host": host,
"cfgHost": cfgHost,
}).Warn("Host doesn't match")
return "", "", nil
}
if authConfig.IdentityToken != "" {
return "", authConfig.IdentityToken, nil
}
return authConfig.Username, authConfig.Password, nil
})
}
```
This logic resides in the following file :
`daemon/containerd/resolver.go` .
In the case when using the containerd storage feature when setting the
`cfgHost` variable from the `authConfig.ServerAddress` it will always be
empty. Since it will never be returned from the NativeStore currently.
Therefore Docker Hub images will work fine, but anything else will fail
since the `cfgHost` will always be the `registry.DefaultRegistryHost`.

commit 8a30653ed5 introduced a sync.Once
to allow for the config-directory (and home-dir) to be looked up lazily
instead of in an `init()`.
However, the package-level `configDir` variable can be set through two
separate paths; implicitly (through `config.Dir()`), and explicitly,
through `config.SetDir()`. The existing code had no synchronisation for
this, which could lead to a potential race-condition (code requesting
`config.Dir()` and code setting a custom path through `config.SetDir()`).
This patch adds synchronisation by triggering the `sync.Once` as part of
`config.SetDir()` to prevent it being triggered later (overwriting the
value that was set). It also restores the `resetConfigDir()` utility that
was removed in 379122b033, to allow resetting
the `sync.Once` for this test.
In general, we should get rid of this package-level variable, and store
it as a config on the client (passing the option to locations where its
used instead).

the "golang.org/x/sys/execabs" package was introduced to address a security
issue on Windows, and changing the default behavior of os/exec was considered
a breaking change. go1.19 applied the behavior that was previously implemented
in the execabs package;
from the release notes: https://go.dev/doc/go1.19#os-exec-path
> Command and LookPath no longer allow results from a PATH search to be found
> relative to the current directory. This removes a common source of security
> problems but may also break existing programs that depend on using, say,
> exec.Command("prog") to run a binary named prog (or, on Windows, prog.exe)
> in the current directory. See the os/exec package documentation for information
> about how best to update such programs.
>
> On Windows, Command and LookPath now respect the NoDefaultCurrentDirectoryInExePath
> environment variable, making it possible to disable the default implicit search
> of “.” in PATH lookups on Windows systems.
With those changes, we no longer need to use the execabs package, and we can
switch back to os/exec.

(github.com/docker/docker/commit/18c9b6c6455f116ae59cde8544413b3d7d294a5e).
Commit b83bc67136 (v23.0.0, but backported to
v20.10) added a warning if no "current" config file was found but a legacy
file was, and if the CLI would fall back to using the deprecated file.
Commit ee218fa89e removed support for the

Relates to the deprecation, added in 3c0a167ed5
The docker CLI up until v1.7.0 used the `~/.dockercfg` file to store credentials
after authenticating to a registry (`docker login`). Docker v1.7.0 replaced this
file with a new CLI configuration file, located in `~/.docker/config.json`. When
implementing the new configuration file, the old file (and file-format) was kept
as a fall-back, to assist existing users with migrating to the new file.
Given that the old file format encourages insecure storage of credentials
(credentials are stored unencrypted), and that no version of the CLI since
Docker v1.7.0 has created this file, the file is marked deprecated, and support
for this file will be removed in a future release.
This patch adds a deprecation warning, which is printed if the CLI falls back
to using the deprecated ~/.dockercfg file.
