20138a81bc docker kill: don't set default signal on the client side
The default signal is already determined by the daemon, so the
CLI should not send a signal.

- Prevent completion on "create" subcommands to prevent them
  from completing with local filenames

0c2d0072c4 Sleep for 1.5 seconds before looking at the resize error
This test is very flaky, the retry loop runs for 550ms and some more, 750ms is
cleary not enough for everything to set and for the cli to return the tty resize
error. A sleep of 1.5 seconds in this test should be enough for the retry loop to
finish.

9598c4c905 Retry initializing TTY size a bit more
I some cases, for example if there is a heavy load, the initialization of the TTY size
would fail. This change makes the cli retry 10 times instead of 5 and we wait
incrementally from 10ms to 100ms

Relates to #3554

7b4d7717b1 Always set the console size
This check doesn't really make sense because the client doesn't know on what
OS the daemon is really running.
The daemon uses the console size on creation when available (on windows).

aaa912c9f7 move commonly used top-level commands to the top of --help
This adds a new annotation to commands that are known to be frequently
used, and allows setting a custom weight/order for these commands to
influence in what order they appear in the --help output.

I'm not entirely happy with the implementation (we could at least use
some helpers for this, and/or make it more generic to group commands
in output), but it could be a start.

For now, limiting this to only be used for the top-level --help, but
we can expand this to subcommands as well if we think it makes sense
to highlight "common" / "commonly used" commands.

214cd05aa1 create/run: remove default --stop-signal
The DefaultStopSignal const has been deprecated, because the daemon already
handles a default value. The current code did not actually send the default
value unless the flag was set, which also made the flag description incorrect,
because in that case, the _daemon's_ default would be used, which could
potentially be different as was specified here.

This patch removes the default value from the flag, leaving it to the daemon
to set a default.

9342ec6b71 ForwardAllSignals: check if channel is closed, and remove warning
Commit fff164c22e modified ForwardAllSignals to
take `SIGURG` signals into account, which can be generated by the Go runtime
on Go 1.14 and up as an interrupt to support pre-emptable system calls on Linux.

With the updated code, the signal (`s`) would sometimes be `nil`, causing spurious
(but otherwise harmless) warnings to be printed;

    Unsupported signal: <nil>. Discarding.

To debug this issue, I patched v20.10.4 to handle `nil`, and added a debug line
to print the signal in all cases;

```patch

This patch checks if the channel is closed, and removes the warning (to prevent warnings if new
signals are added that are not in our known list of signals)

We should also consider updating `notfiyAllSignals()`, which currently forwards
_all_ signals (`signal.Notify(sigc)` without passing a list of signals), and
instead pass it "all signals _minus_ the signals we don't want forwarded":

dace8fdc75 formatter: reduce minimum width for columns in table-view
The tabwriter was configured to have a min-width for columns of 20 positions.
This seemed quite wide, and caused smaller columns to be printed with a large
gap between.

612567cb21 Merge pull request #2678 from thaJeztah/fix_rm_force_exit_status
Return zero exit-code when force-removing non-existing containers
2020-08-27 14:40:08 -07:00
9a071a993a Return zero exit-code when force-removing non-existing containers
When using `docker rm` / `docker container rm` with the `-f` / `--force` option, attempts to remove non-existing containers should print a warning, but should return a zero exit code ("successful").

Currently, a non-zero exit code is returned, marking the removal as "failed";

	$ docker rm -fv 798c9471b695
	Error: No such container: 798c9471b695
	$ echo $?
	1

The command should match the behavior of `rm` / `rm -f`, with the exception that
a warning is printed (instead of silently ignored):

Running `rm` with `-f` silences output and returns a zero exit code:

    touch some-file && rm -f no-such-file some-file; echo exit code: $?; ls -la
    # exit code: 0
    # total 0
    # drwxr-xr-x    2 sebastiaan  staff    64 Aug 14 12:17 .
    # drwxr-xr-x  199 sebastiaan  staff  6368 Aug 14 12:13 ..

    mkdir some-directory && rm -rf no-such-directory some-directory; echo exit code: $?; ls -la
    # exit code: 0
    # total 0
    # drwxr-xr-x    2 sebastiaan  staff    64 Aug 14 12:17 .
    # drwxr-xr-x  199 sebastiaan  staff  6368 Aug 14 12:13 ..

Note that other reasons for a delete to fail should still result in a non-zero
exit code, matching the behavior of `rm`. For instance, in the example below,
the `rm` failed because directories can only be removed if the `-r` option is used;

    touch some-file && mkdir some-directory && rm -f some-directory no-such-file some-file; echo exit code: $?; ls -la
    # rm: some-directory: is a directory
    # exit code: 1
    # total 0
    # drwxr-xr-x    3 sebastiaan  staff    96 Aug 14 14:15 .
    # drwxr-xr-x  199 sebastiaan  staff  6368 Aug 14 12:13 ..
    # drwxr-xr-x    2 sebastiaan  staff    64 Aug 14 14:15 some-directory

This patch updates the `docker rm` / `docker container rm` command to not produce
an error when attempting to remove a missing containers, and instead only print
the error, but return a zero (0) exit code.

With this patch applied:

    docker create --name mycontainer busybox \
    && docker rm nosuchcontainer mycontainer; \
    echo exit code: $?; \
    docker ps -a --filter name=mycontainer
    # df23cc8573f00e97d6e948b48d9ea7d75ce3b4faaab4fe1d3458d3bfa451f39d
    # mycontainer
    # Error: No such container: nosuchcontainer
    # exit code: 0
    # CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
