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.

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.

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.

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..
https://github.com/containers/toolbox/pull/1024
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.

Commit 6c86cabbe5 changed the command line interface to behave
a lot similar to that of github.com/coreos/toolbox, which makes things
easier for those switching over from it. Make it conditional so that
only those OS distributors who truly need it may enable it, and
restore the previous behaviour as the default.
The tests were updated to test the default behaviour that the vast
majority of users would be seeing. Ideally, the test suite would be run
twice with the migration path turned off and on. However, that would
require a more intrusive surgery of the test suite and likely make it
slower. It might not be worth the hassle because of the small number
of users who should be using the migration path.

We need to know if the latest changes in the libc (that is dynamically
linked to the binary) causes problems in containers based on older
releases of Fedora.
The estimate of the version numbers is very crude and does not follow
the upstream schedule. That should not be a problem, though.
A part of an existing test has been reused and made into a helper
function to implement this.
This increases the run time of the test suite on Rawhide which already
takes longer than the same test suite on released versions of Fedora.
Make up for it by increasing the timeout by 2 minutes.

The 'die' function is a remnant from times before the system tests
rewrite. It served for writing an error message and then failing
the test. Since the rewrite it is no longer present. Instead, simply
use 'false' in case a caching step fails.

This allows to run the test suite without having to worry about blasting
the whole local state of Podman.
This is done by creating a configuration file with a custom path for the
storage of Podman and specifying the config file using an env var.
The used location for the temporary storage is located either under
XDG_CACHE_HOME and if the one is not defined, $HOME/.cache is used
instead. The data are namespaced. This follows the XDG Base Directory
Specification[0]. Other locations could be /tmp or /run but those
locations usually use tmpfs and that filesystem can not be used by
Podman[1] due to missing features in tmpfs.

Unlike the following test this one tests using the content of the
toolbox(1) manual page in man. man has to be present in PATH for this
test to be relevant.
Also, this changes the text used to test the output. The current text
can be found in the added short help message and that causes the test
to pass even though it should not. Instead, look for the text in the
"header" of the manual page.
https://github.com/containers/toolbox/pull/837
Fedora CoreOS systems do not have the man command installed. Running
toolbox --help on such a system results in a "man(1) not found" error.
As a compromise for systems without man, we added a simple help text
showing the most commonly used toolbox commands and an URL that direct
users to the Toolbox website where they can find the manuals in Markdown
format.

These tests need to be implemented in the future but they require some
magic with socat or similar tools as entering a container is creating
a new subshell and that is hard to monitor from a bash script. Better
not to forget then.
https://github.com/containers/toolbox/pull/915
Due to docker rate limiting we can not rely in docker.io for
retrieving the images.
This was detected when executing our tests for podman fedora
gating pipeline. Our busybox image was not downloaded and
one of the list tests was failing.
Using the current working directory for cache is not a good solution
since the test files may reside in a location that is unwritable (e.g.,
/usr/share). The `BATS_RUN_TMPDIR` variable should point to a location
that is sure to be writeable from the test suite.
https://github.com/containers/toolbox/pull/850
A subsequent commit will add support for configuration files, which can
override the default toolbox image. Since this override affects all
commands, it effectively ends up adding a fourth option to the 'enter'
command, other than the existing options to change the distribution,
release and container. This makes it a lot more difficult to reason
when only 'toolbox enter --release N' is enough to enter the created
container.
https://github.com/containers/toolbox/pull/828https://github.com/containers/toolbox/pull/851
The 'toolbox run' command has one downside: all newlines contain
a carriage return (CR). This is caused by the unconditional use of the
--tty option in `podman exec`[0]. In these particular tests this can be
worked around by not printing a newline at all.
Another quirk around partial is to check the last line of the output.

The output of `podman build` has changed a bit. Each line of log
describing the build is now in the format of:
- STEP i/n: msg
instead of:
- STEP i: msg
where i is the current step and n the maximum number of steps.
The exact format is not important for the purpose of testing Toolbox, so
we may fallback to partial string testing.
Also the latest step ("COMMIT") seems to no longer be considered a step,
so just check for the word.
https://github.com/containers/toolbox/pull/846
This makes 'toolbox', without any commands specified, behave a lot like
'toolbox enter'. When there aren't any toolbox containers, it will
offer to create a new container matching the same parameters passed to
the command. If there's just one toolbox container available, then it
will fall back to it.
This makes the command line interface a lot similar to that of
github.com/coreos/toolbox, which makes things easier for those
switching over from it.

Some people create images manually. If such created images are recognize
as toolbox images (they have the proper labels) but do not have
a name/tag then 'toolbox list' will panic due to index being out of
range.
https://github.com/containers/toolbox/pull/800
Not having the corresponding image for UBI toolbox containers show up
in 'toolbox list' is a rough edge. However, the whole UBI feature is
a bit experimental. It's about a gratis RHEL environment getting
created in a jiffy on any host, which is something that hasn't been
done before, and those containers also suffer from various shortcomings
because of the limited package set of UBI.
So it's not that big of a problem if it takes a release or two to
hammer out the details. Especially since it's likely that there will
be a special Toolbox-specific image that's created out of the UBI RPM
repositories, which will likely have the com.github.containers.toolbox
label.
There's also the issue that 0.1.0 needs to be finished, and for that
the the churn needs to be kept down. Changing the labels can very
likely lead to compatibility issues in the future, because of which it
either can't be removed for a while or the wrong images start to get
listed. Some of the older labels have finally been removed, so it's
better not to add more to the list.
In short, this problem will likely fix itself in the coming months, so
it's wise not to create complications trying to rush through a fix.

UBI[0] does not have the recommend Toolbox labels used to track whether
an image/container is truly a toolbox image/container. Thankfully, they
have a number of labels to choose from that we can use to identify the
image. The "com.redhat.component=ubi8-container" seems to be ideal.
The approach of using the UBI8 label introduces one problem though. If
we were to use only one set of labels for both images and containers,
containers created with Podman and not Toolbox from UBI8 would also be
marked as toolbox containers. This is not desired and therefore there
are now two sets of labels. Ones for images where the new label has been
added and other for containers that stays the same.
Since the rewrite of the system test suite[0] we've relied on the Zuul
playbooks for taking care of caching images using Skopeo for increasing
the reliability of the tests (in the past the instability of the Fedora
registry caused problems). This state is problematic if we want to use
the tests in other environments than the Zuul CI. This moves the caching
from Zuul into the system tests.
Currently, Bats does not support officially suite-wide setup and
teardown functions. The solution I chose was to add two new test files
that are executed before and after all tests. This may complicate the
execution of cherry-picked tests but that is not a very common use case
anyway.
The tests are now to some extent capable of adjusting to the host
environment. This is meant in the sense of: I'm running on RHEL, the
"default image" is UBI; I'm running on Fedora, the "default image" is
fedora-toolbox. This mechanism relies on os-release, which is the same
as what Toolbox itself uses.

The fedora-toolbox:32 image is the first of images in the renamed
toolbox image repository[0]. With the change we can drop the
pull_image_old() function because it was kept only for the old image.
Seems like newer version of ShellCheck checks the validity of variable
names (SC2153). This caused a false positive, so I silenced it.

The system test refactor[0] replaced the 'run_toolbox' helper function
with 'run toolbox', which is a normal invocation of Toolbox. This makes
it impossible to override Toolbox used during the tests using env var.

Since commit b27795a03e, each section of the test suite starts
and ends with a clean Podman state. This includes removing all images
from the local containers storage. Therefore, the images get downloaded
multiple times during the course of the test suite.
This commit restores the earlier behaviour where the images would get
downloaded only once, by copying them to separate directories outside
the local containers storage and then restoring them when the tests
are run.

The bats-support[0] and bats-assert[1] libraries extend the
capabilities of bats[2]. Mainly, bats-assert is very useful for clean
checking of values/outputs/return codes.
Apart from updating the cases to use the libraries, the test cases have
been restructured in a way that they don't depend on each other anymore.
This required major changes in the helpers.bats file.
Overall, the tests are cleaner to read and easier to extend due to the
test cases being independent.
Some slight changes were made to the test cases themselves. Should not
alter their final behaviour.
There will be a follow up commit that will take care of downloading of
the tested images locally and caching them using Skopeo to speedup the
tests and try to resolve network problems when pulling the images that
we experienced in the past.

regexp.MatchString() only returns an error if the pattern can't be
parsed. In this case, the pattern is a constant string literal, so
unless there's a programming mistake, the pattern should always be
parsable and there should never be an error.
What really needs to be checked is whether the 'containerName' matched
the pattern or not. That's indicated by the bool return value
'matched'.

... by running updatedb(8) on start-up and then at 24 hour intervals
from there on.
This isn't as nice as using a systemd.timer(5) because the current
timer goes away when the toolbox container is stopped and is rearmed
when it's started. Therefore, repeatedly restarting a container will
also run updatedb(8) again and again.
Fortunately, this isn't so bad with updatedb(5) implementations that
are able to incrementally update the database [1], which is what Fedora
uses.
The 24 hour interval was chosen based on the systemd.timer(5) settings
used by Fedora's mlocate RPM.

This is one more step towards enabling toolbox(1) to be run as root.
When invoked as 'sudo toolbox ...' there's no user or session D-Bus
instance available for the root user, which prevents the use of D-Bus
services like org.freedesktop.Flatpak.SessionHelper.
The code is forgiving to runtime errors when reacting to file system
events because it's not worth abruptly terminating the entry point
because of what might be a passing error. However, it's a lot stricter
when initially configuring the container because the failure mode isn't
as surprising for the user and it's worth starting from a valid state.
https://github.com/containers/toolbox/issues/267
When I added the test that looked at the logs of a toolbox, I did not
realize that the startup of a toolbox takes some time. That caused the
CI to flake even more than usual.
The solution I used was inspired by a helper function in Podman's test
suite (WaitContainerReady()).

For some reason running 'toolbox run echo Hello World' in the tests in
the environment of Zuul is causing problems. Bats saves the output of
ran command to $output that can be then checked if it contains the right
output. This variable sometimes holds in this case the right output
("Hello World") but more often it is blank, causing the tests to fail.
I don't know the culprit, so for now I'm commenting out the checks to
make the CI pass again.

In the Go implementation, when the 'rm' and 'rmi' commands fail to
remove a container or image, they don't use a non-zero exit code.
There's currently no nice fix for this. So, the tests have been
adjusted as a temporary measure.

The tests introduced by commit b5cdc57ae3 have proven to be
rather unstable due to mistakes in their design. The tests were quite
chaotically structured, and because of that images were deleted and
pulled too often, causing several false positives [1, 2].
This changes the structure of the tests in a major way. The tests
(resp. commands) are now run in a manner that better simulates the way
Toolbox is actually used. From a clean state, through creating
containers, using them and in the end deleting them. This should
reduce the strain on the bandwidth and possibly even speed up the
tests themselves.
