Libyang is smart, it "fixes" the timezone for you, this was overriden by a
hack in netconf.py and restconf.py, but what you really want is to see
in operational what the current timezone is.
Do not allow the topology matcher to setup a LAG where one link is
running at 10G while the other one runs at 1G, since the bond will
never use the 1G port as long as there the 10G link is up.
To run LAG tests on hardware, we have to make sure that the chosen
links are running at the same speed. We do not want to require a
specific link speed from the logical topology, as the real requirement
is merely that the two (or however many) links are of the _same_
speed, not any _particular_ speed.
Rather than having to complicate the topology matcher, let it take
care of the common pattern of matching requirements to provided
features, then let tests pass custom node/edge matchers for the
complicated cases.
Unclear if the libyang merge operation actually does it's job of merging
all the data properly in the restconf backend.

When first starting up the YANG models are downloaded. Initially all
were printed on the test console, so this was later changed to become
a sort of progress output. However, that broke tap output, causing a
missing leading '#' for the final "YANG models downloaded." message.
Thist patch drops the output entirely from the netconf transport, it
was never added to the restconf transport.

This commit adds two SVGs for previewing the virtual test topologies.
quad: fix a lot of copy-paste mistakes, rename nodes and ports to their
correct names. Replace shell comments with C++ style comments,
not all tools, e.g., dotty, support shell comments. The neato
absolute positioning has also been fixed to make it possible to
see all the edges, to facilitate this the used ports have been
swapped around a abit. Colors are used according to the schema
agreed on for tests. Finally, a second link for lag tests have
been added between dut2 and dut3.
dual: coloring similar to quad, update to new edge attribute matcher.

Introduce a parameter in IsolatedMacVlans to set interfaces up by
default. This removes the need to manually bring the interface up
inside the addip function.
Implemented logic to check if the system supports required services.
Logical edges with 'requires' fields are mapped only if physical edges
provide corresponding services. If not, the test is skipped.
This ensures that tests only run when the required services are available
in the test system configuration.
Fixes#654
Being able to check for a TCP based service is generally useful, not
only for NETCONF. Therefore, break it out to a separate function that
allows any port to be queried.
Using `sys.argv[0]` does not quite achieve the effect we want, namely
that any (test-case, $PYTHONHASHSEED) tuple should always default to
the same transport.
For example, the following two examples should always use the same
transport:
$ make PYTHONHASHSEED=1337 test-sh
infamy0:test$ ./case/ietf_system/hostname/test.py
$ make PYTHONHASHSEED=1337 test-sh
infamy0:test$ cd ./case/ietf_system/hostname
infamy0:hostname$ ./test.py
But, since their argv[0]'s are different, they don't.
Therefore use the _last two components_ of argv[0]'s full path
instead. This should:
- Spread the allocation over an entire suite run, since the
penultimate component is usually the test name.
- Keep the allocation stable when test code is modified (which is
common during debugging of failing tests)
- Avoid instabilities stemming from the local storage location (i.e.,
home directory names etc.)
The somewhat clumsy construct of resolving a logical port name to its
physical counterpart has been with us from Infamy's inception:
_, physical_port = env.ltop.xlate(logical_node, logical_port)
This is needlessly verbose. Since devices already have access to the
mappings which applies to it, make them easy to access:
target = env.attach("target")
# Get physical port names via the subscript operator
target["data0"]
* Use new cleanup in infamy to ensure the boot order gets restored
* Use new boot order in operational and use RPC to set boot order
to remove all SSH commands.
If a test need to clean up itself disregarding test status,
it can add an optional test-cleanup phase.
This is useful if the test in some circomstances leave the device in a
bad state. This can be used to restore the unit to its ordinary state.
Furl answers the question "is this URL serving the content I expect?"
Sometimes, we might be asking a server that in the middle of being
reconfigured, is crashing, is buggy, etc. - in which case it might RST
the connection. In that case the answer to the question is "False" and
not "BURN IT ALL DOWN!!"
If the callable threw an exception, then the process running inside
the netns would exit before sending back a value on the tx pipe, which
meant that `rx.recv()` would hang in the original process.
Make sure that we catch any exceptions, and send that instead of the
result over the pipe in those scenarios. Then in the original process,
re-raise the exception.
Fixes the following issue when deleting /infix-services:mdns/interfaces,

Replace the existing remove-module-names-pass in the RESTCONF
transport -- which only worked for top-level containers -- with
libyang's standard `.print_dict()` used by the NETCONF transport
implementation.
As a bouns, the implementation of `.get_iface()` is now transport
agnostic.
This patch adds latest symlinks to the curiOS containers to make system
upgrades easier. I.e., a user can now reference the bundled image with:
set image oci-archive:/lib/oci/curios-httpd-latest.tar.gz
So that when they upgrade to the latest Infix, which might include an
update of curiOS httpd, they will get a seamless upgrade also of the
container(s) running.

This is a specialized namespace, containing two ports,
which (hopefully) acts as completely transparent "bump-on-the-wire"
bridge.
Useful in scenarios where you want to test what happens when the flow
of packets between two nodes is disrupted. E.g., for testing fail-over
behavior in dynamic routing protocols, L2 redundancy, VRRP etc.
Now that we're using the `passthru` mode of MACVLANs, it seems we can
rely on the parent interface's promiscuity going down to 0 as an
indication that the kernel has completed the removal of the interface,
and will accept the creation of a new one.
