With --color=auto, coloring is enabled based on the .enable/.disable
termcolors files.
Likewise, when we enable coloring, we parse the color palette from the
.schem termcolors files.
The termcolors files are searched by finding the best match depending
on the terminal and application name. Note, that if we find a matching
file like "nmcli@xterm.enable" we still allow loading the palette from
a less specific file like "nmcli.schem" and vice versa. That was already
done before.
Previously, the search was done by calling several layers of functions, and having
in/out arguments "color_option" and "p_palette_buffer". in/out paramters
here seems confusing to me, as they are state that gets modified and carried
along.
Instead, rework the functions to clearly separate between input
and output arguments.
Also, in the auto-case, check_colors() now first determines whether
coloring is enabled, before even starting loading the palette.
This avoids loading the palette until we are sure that we need it.
The NmCli variables is essentially a global variable of *everything*.
The set_color() function and its helpers only need a particular
part of it. Instead, of passing the entire global state to them,
only pass what they need.
It makes it clearer which parts are actually relevant. Turns out,
it only actually touches a resonable small part of the global state.
If the hints parameter to the agent request wasn't empty, ask
specifically for the 802-1x keys listed in the hints and skip the
guessing. I didn't add human readable names for all of the 802-1x
settings, it could be useful to do for at least the three 802-1x
properties that add_8021x_secrets already knows about because
those may have translations.
Now that nmcli initiates a scan before displaying Wi-Fi networks,
the stub service must properly support that as well.
For the moment, the stub service chooses "now" as LastScan timestamp.
This causes nmcli not to trigger a new scan, because nmcli gives
unstable output if multiple nmcli processes in parallel race to
trigger a Wi-Fi scan. That should be fixed.
When link auto-negotiation is enabled, by default the network device
advertises all the supported speed and duplex modes in order to
negotiate the fastest link speed with the remote endpoint.
It is possible anyway to configure the device to just advertise and
accept a subset of supported modes.
This could be useful to properly enforce gigabit speeds on Ethernet:
as stated in IEEE 802.3 specification, auto-negotiation is mandatory
for 1000Base-T and 10GBase-T standards.
Allow specific values to 802-3-ethernet.speed and 802-3-ethernet.duplex
properties also when 802-3-ethernet.auto-negotiate=yes: this will
result in link auto-negotiation advertising the specified speed/duplex
mode as the only one available.
It's not libnm's responsibility to hide the banner
depending on the VPN state. libnm should cache and expose
NetworkManager's state, and if the VPN connection has
a banner there, it should be returned.
The previous behavior was since ever in libnm, and in libnm-glib since
the banner was introduced in commit e5b834c1f9.
I think it's wrong if libnm tries too hard putting additional logic
on top of what is on D-Bus.
When a property getter returns an empty/missing strv-array, in multi-line
mode we should not print any lines.
To get that right, we must mark the cell as STRV type, even if there is no value
provided.
Previously, with text_out_flags having NM_META_ACCESSOR_GET_OUT_FLAGS_STRV
and value being NULL, we would not set
cell->text_format = PRINT_DATA_CELL_FORMAT_TYPE_STRV;
and thus, later on the value would be treated as a missing (plain)
string.
The property getter for certain properties tries to return
a strv array.
In this case, the result should be identical, whether an
empty strv array or NULL is returned.
Let _ip_config_get_routes() return %NULL if there are no routes.
This should have no practical difference, but it actually exposes
a bug in "cli/common/utils.c", which was previously hidden by
not commonly returning %NULL. This bug will be fixed in the
next commit.
Currently, nmcli does not sort the list of available connections
for display. Instead, it shows them in the order as NetworkManager
exposes them on D-Bus.
Previously, test-networkmanager-service.py, would generate the list
of available connections by iterating the connections dictionary.
In Python (at least until Python 3.6), the order when iterating over
dictionaries is undefined. This inconsistancy lets tests behave
differently depending on the python version. Possibly with Python
3.4 and 3.5, tests might even behave differently between individual
runs (since Python there uses siphash with a randomized hash seed).
It is safer to enable send-sci by default because, at the cost of
8-byte overhead, it makes MACsec work over bridges (note that kernel
also enables it by default). While at it, also make the option
configurable.

Check the wpa_flags and rsn_flags values to see if the network needs the
password added to the 802-11-wireless-security settings. The current
ap_flags check alone would only trigger the password to be sent for WEP
networks. Also remove unneeded initialization of the three variables.
Commands that fail with G_DEBUG=fatal-warnings produce unstable
output like
(process:10743): GLib-CRITICAL **: 16:29:13.635: g_ptr_array_add: assertion 'rarray' failed
To workaround that, add a new option for marking the output as unstable.
An alternative might be to extend the replace_stdout, replace_stderr
arguments to support more powerful matching, like by specifying regular
expression for replacing. However, it's just too complicated. Add a simpler
workaround by passing _UNSTABLE_OUTPUT.
How does `nmcli -f ALL dev show $DEV` look, if it references
a connection that is invisible to the user?
Note in the output:
CONNECTIONS.AVAILABLE-CONNECTIONS[1]: (null) | (null)
At several places, "test-networkmanager-service.py" uses generated numbers
with a defined seed. For example, generated connection's UUID is
generated in a predictable, but randomized way (if you forgive the
inprecise use of the word "random" in context of using a deterministic
seed).
Aside the connection's UUID, this becomes more interesting in the next commit
where the stub server generates a list of IP and DHCP settings in a predictable
randomized way.
For "clients/tests" we spawn the test service multiple times, but also
create similar environments by calling init_001(). This is done for
convenience, where out of lazyness all the tests share one setup. But it's
still a good idea that these tests generate slightly different setups,
wherever applicable. this increases the possible setups which get tested.
For example, the number of static IPv4 addresses (the following commit) is
interested to explicitly test for zero or a non-zero number of
addresses. If all tests happen to use the same seed, the tests are expected
to also generate the same number of addresses, and we miss an opportunity to
hit interesting test cases.
There is still no guarantee that all interesting cases are hit, the chances are just
better. The approach of generating the setup randomly, does not preclude that
the stub-server allows to explicitly configure the setup. However, due to the
sheer number of combinations that might be interesting to test, it's much simpler
to rely on some randomization and have the justifid hope we catch interesting cases.
Also in terms of runtime of the test, the cli unit tests should complete within
few seconds. Testing every combination would result in huge tests and long runtimes.
Also, the patch refactors generating random numbers in
"test-networkmanager-service.py". For example, it introduces
Util.RandomSeed(), which can be used to generate a sequence of different
random numbers. It works by having an internal state and a counter which is
combined to chain the seed and generate different numbers on each call.
There's a couple of places where compose the output using nmc_print().
However, most of them (such as connectivity status or logging level) are
mostly one-line outputs where pager wouldn't make sense. These two stand
out.
