When describing the --authfile option, the word 'private' is used to
refer to images needing authentication. Using the same word shortens
the text so that the word 'custom' can be used in the same way as in the
other examples.

It turns out that Viper's custom error implementations use non-pointer
receivers, whereas often people assume pointer receivers. This can
cause confusion when trying to use errors.As(...) with those errors [1].
Secondly, Viper may or may not throw ConfigFileNotFoundError depending
on its build tags.

Currently, the container name and release are only validated if they
were specified as command line options. Neither the value of release
in the configuration file nor the container name generated from an
image are validated.
There's also a lot of repeated code in the command front-ends to
validate the container name and release. This opens the door for
mistakes. Any adjustment to the code must be repeated elsewhere, and
there are subtle interactions and overlaps between the validation code
and the code to resolve container and image names.
It's worth noting that the container and image name resolution happens
for both the command line and configuration file options, and generates
the container name from the image when necessary.
Therefore, validating everything while resolving cleans up the command
front-ends and increases the coverage of the validation.
This introduces the use of sentinel error values and custom error
implementations to identify the different errors that can occur while
resolving the container and images, so that they can be appropriately
shown to the user.

Currently, if an invalid or unsupported string is specified as the
distro on the command line or in the configuration file, then it would
silently fallback to Fedora. This shouldn't happen.
It should only fallback to Fedora when no distro was specified and
there's no supported Toolbox image matching the host operating system.
If a distro was explicitly specified then it should either be supported
or it should error out.
The test cases were resurrected from commit 8b6418d8aa.
https://github.com/containers/toolbox/issues/937https://github.com/containers/toolbox/pull/1080
The terms 'default' and 'fallback' are used to mean very specific
things in this context.
The 'default' values are those that are used when the 'create', 'enter'
and 'run' commands were used without any option. These values are
picked to match the host operating system.
However, if there's no supported Toolbox image matching the host
operating system, and no options were provided to the 'create', 'enter'
and 'run' commands, then the 'fallback' values are used as a last
resort.
Consistently using this terminology leads to a clear mental model and
makes the code easier to read.
This rough arrangement of the code was already being used for
'release', and has now been been extended to 'container name prefix'
and 'distro'. The suffix for the 'fallback' values was simplified to
'Fallback', instead of 'DefaultFallback'.
https://github.com/containers/toolbox/issues/937https://github.com/containers/toolbox/pull/1080
Figuring out the container name prefix for a given image only needs to
happen as part of resolving the final Toolbox container name from the
given command line and configuration options.

The -Dmigration_path_for_coreos_toolbox option enables a different code
path that's currently not tested by the CI at all. In fact, since it's
a build-time option, the corresponding code path is not even built by
the CI.
To properly support the -Dmigration_path_for_coreos_toolbox option, it
needs to be covered by the CI. This is a step in that direction by
running the unit tests on it.
https://github.com/containers/toolbox/pull/1095
A subsequent commit will introduce builds performed with the
-Dmigration_path_for_coreos_toolbox option to the CI. It will be good
to avoid duplicating the build and installation steps for builds with
and without the -Dmigration_path_for_coreos_toolbox option.

A subsequent commit will introduce builds performed with the
-Dmigration_path_for_coreos_toolbox option to the CI. It will be good
to avoid duplicating the installation of RPM packages, Git submodule
handling, and the listing of various debug and version information for
builds with and without -Dmigration_path_for_coreos_toolbox option.

This will provide a path forward to those who stumble across the POSIX
shell implementation and don't know how to use the Go implementation.
https://github.com/containers/toolbox/pull/1094
The subsequent commit will touch the POSIX shell implementation, and
hence ShellCheck needs to be run on it.
As long as the POSIX shell implementation is part of the Git repository,
ShellCheck needs to keep running on it, unless it causes some serious
problems. The ShellCheck test is very fast, and the reassurance and
mental peace that it provides is invaluable.
This reverts commit 8c1d441916.

This isn't causing any problems at the moment. However, the test can
break if the order in which the command line arguments are validated
changes. eg., if the presence of a command is checked before the
release, then the error message will be different.

From now on, Debarshi Ray <debarshir@gnome.org> will show up as
Debarshi Ray <rishi@fedoraproject.org>.
Toolbox isn't quite a GNOME project (it doesn't use elements from the
GNOME platform, like GLib), even though it's part of the same
ecosystem and many Toolbox contributors are also GNOME contributors.
Toolbox was conceived to improve the developer experience on Fedora
Silverblue, and expanded over time to cover other use-cases (eg.,
troubleshooting the operating system) and Fedora editions (eg., CoreOS
and Workstation). Even though there's a growing number of users on
other distributions, they are not the primary reason for Toolbox to
exist.
Toolbox heavily depends on Podman, and as a result is more aligned with
the Containers organization on GitHub than anything else, which is
driven, to a large degree, by Fedora contributors.
Hence, my desire to use my Fedora identity.
https://github.com/containers/toolbox/pull/1083
When a command is executed with toolbox run and it returns a non-zero
exit code, it is just ignored if that exit code is not handled. This
prevents users to identify errors when executing commands in toolbox.
With this fix, the exit codes of the invoked command are propagated
and returned by 'toolbox run'. This includes even exit codes returned
by Podman on error.

Without stderr being attached stderr output of the invoked command goes
into stdout.
Behaviour before:
; output="$(toolbox run /etc)"
Error: failed to invoke command /etc in container <name-of-container>
; echo -e "$output"
/bin/sh: line 1: /etc: Is a directory
/bin/sh: line 1: exec: /etc: cannot execute: Is a directory
Behaviour after:
; output="$(toolbox run /etc)"
/bin/sh: line 1: /etc: Is a directory
/bin/sh: line 1: exec: /etc: cannot execute: Is a directory
Error: failed to invoke command /etc in container <name-of-container>
; echo -e "$output"
https://github.com/containers/toolbox/pull/1013
Passing '--tty' to 'podman exec' unconditionally causes Podman to
allocate a pseudo-TTY for the command execution. This causes problems
with piping (values not being piped in and values being piped out with
carriage return at the end of a line). The solution is to track the
presence of a terminal on stdin/stdout and based on its presence use the
'--tty' flag.
Original behaviour:
; echo foo | toolbox run less
; toolbox echo foo | od -c
0000000 f o o \r \n
0000005
New behaviour:
; echo foo | toolbox run less
foo
; toolbox echo foo | od -c
0000000 f o o \n
0000004
As seen in the 'Piping in' example, the value gets only printed into
stdout. Not ideal from the point of view of using 'less' (or similar
tools) but still a move forward.
Based on a discussion in Podman's bugtracker[0].

Calling 'podman system cleanup' causes problems with containers/images
in a separate Podman root. Despite being stored elsewhere, they are
still under Podman's influence and the cleanup removes them. Also,
running containers (outside the scope of the tests) still got affected
by this call and e.g., lost the ability to follow terminal size changes.
Despite the raised concerns, to ensure proper cleanup of any Podman
state, the reset still needs to be done. Thus, do it only once during
the test suite teardown, moving the potential source of problems to a
single position..

The previous commit added a means to generating the completion scripts
and this one plugs that into the build system.
A new build option 'install_completions' has been introduced. Set to
'True' by default.
Completions for bash and fish use pkg-config for getting the preferred
install locations for the completions. If the packages are not
available, fallbacks are in-place.
The 'completion' subdir has been kept to work around the ideology of
Meson that does not allow creating/outputing files in subdirectories nor
using the output of custom_target() in install_data().

Cobra (the CLI library) has an advanced support for generating shell
completion. It support Bash, Zsh, Fish and PowerShell. This offering
covers the majority of use cases with some exceptions, of course.
The generated completion scripts have one behavioral difference when
compared to the existing solution: flags (--xxx) are not shown by
default. User needs to type '-' first to get the completion.

Using a non-supported distribution via `--distro` resulted in a silent
fallback to the Fedora image which confuses users. When a faulty release
format was used with `--release` a message without any hint about the
correct format was shown to the user.
This separates distro and release parsing into two chunks that have
greater control over error reporting and provides more accurate error
reports for the user.
