This check requires additional information about the environment, that
is about the present connections in NMClient.
"nm-meta-setting-desc.c" should be independent from the libnm D-Bus
cache, hence move this code to "settings.c".
The lower layers are concerned with handling settings. They should not
be aware of how to notify about warnings. Instead, signal them via
the warn_fcn() hook.
Options dependant on specific commands (e.g., nmcli connection show
--active) are now allowed to be processed by the next_arg() function.
This would allow autocompletion to expand options belonging to specific
command first, and then global ones.
Note that global options ("--ask" and "--show-secrets") will be auto-completed
everywhere but only if at least a '-' is passed. Command specific ones
(--temporary, --active, --order) will be auto-completed only after the command
they belongs to but without requiring the user to pass a heading '-'.
Example:
'nmcli connection show -a'
will expand '-a' into '--active', but
'nmcli connection add -a`
will expand '-a' into '--ask' (as it is a global option)
This commit fixes also autocompletion for:
nmcli connection modify --temporary
This happens when the connection is in "activating" state and
the connection is a master one waiting for slaves: "check_activated()"
is called by the active_connection_state_cb() and device_state_cb() callbacks.
If the device has already moved to a state >= NM_DEVICE_STATE_IP_CONFIG, the
call to active_connection_state_cb() will end calling
activate_connection_info_finish(), freeing the "info" object. The subsequent
call to device_state_cb() will result in accessing the freed "info".
Just call check_activated() once after registering the
active_connection_state() and device_state_cb() callbacks.
Before commit a63c4d0824 ("cli: use designated initializers for
setting NmcOutputField fields") each field had a @name and a
@name_l10n , which were equal for all properties except for wifi
IN-USE:
{"IN-USE", N_("*")}, /* 15 */
The commit removed @name_l10n so now the displayed name is equal to
the field name. But now:
$ nmcli device wifi list
Error: 'device wifi': invalid field 'IN-USE'; allowed fields:
NAME,SSID,SSID-HEX,BSSID,MODE,CHAN,FREQ,RATE,SIGNAL,BARS,SECURITY,
WPA-FLAGS,RSN-FLAGS,DEVICE,ACTIVE,*,DBUS-PATH
The new field name should be 'IN-USE' and not '*', otherwise scripts
doing "-f IN-USE" will break. As a side effect we now show 'IN-USE'
instead of '*' in the column header, which seems easier to understand:
IN-USE SSID MODE CHAN RATE SIGNAL BARS SECURITY
* default Infra 5 54 Mbit/s 71 ▂▄▆_ WPA2
guest Infra 1 54 Mbit/s 62 ▂▄▆_ WPA2
Fixes: a63c4d0824
We should not violate the global data to track the output data
while it is constructed and printed.
Most of the time, we actually clear the output data anyway --
either before constructing it, or after printing it.
In some cases we didn't, but I think that is a bug. It's really
hard to keep track of this.
The output data should belong to a certain scope and get destroyed
afterwards. Passing it around is very confusing. Don't do that.
To better understand which part of the code have side effects,
split print_data() in a part that mutilates the input array
and a part that only prints.
Don't cast const strings to non-const. And don't track
whether to free a variable in a boolean. Instead, assign
ownership to variables that get destroyed when the function
returns.
The NmCli structure is passed around everywhere and contains all
the state of the program. It is very hard to follow which parts
are used where.
Split out more configuration options to a NmcConfig field. This field
is mostly immutable, and modified at particular places that now can be
easily found.
nmc contains all options and collects output data. It is very hard to
understand what it does. Start splitting it up, and pass arguments along
-- as needed.
Otherwise, changing the structure is difficult because it all depends
on the order (and you don't immdiately see which field is used where).
Also, drop the name_l10n field.
These functions are only used by nm-meta-setting-desc.c. Make them internal.
Unfortunately, they are part of "common.h" which cannot be used without
the rest of nmcli. Still todo.
This part contains static functions and variables to describe
settings. It is distinct from the mechanism to use them, or
access them.
Split it out.
It still uses clients/cli/common.h and clients/cli/utils.h
which shall be fixed next.
They will be moved out of nmcli as they are generally useful.
Even if they happen to be used only inside nmcli, there should
be a better separation between logic (nmcli) and setting decriptions.
Mostly these strings are static. In same cases they are generated
however. Instead of caching them in a static variable, return them
to the caller.
And belatedly fix invoking describe_fcn().
settings.c basically consists of property-type structures and *a lot* of
accessors. All these accessors share the same argument list.
It is very repetitive to specify it over and over again. Also, there
are so many arguments that one is compelled to wrap the lines. All
in all it results in a lot of noise that takes the eye from the important
code.
Also, the argument list is expected to change, so we possibly only
have to change one place.
We shall not only have a PropertyInfo. Most properties share common
behavior, that is, they have a type. Move the function pointers to
a NmcPropertyType structure, so that it can be reused for multiple
properties.
This promotes the idea that properties have a (limited) set of types
with some type specific behaviors. Contrary, to having each property
re-implement fully it's type. E.g. instead of having various property
re-define their full behavior as an "bool", have one property type
"bool" which can be attached to a property.
