A property-info can only have one property-typ-data. That means,
all functions (get_fcn(), set_fcn()) need to either take not
property-typ-data, or they must all accept the same.
That made it hard to mix _get_fcn_nmc_with_default() with setters
that do require a certain property-typ-data. Instead, move the
is_default_func() to the general portion, and let _get_fcn_gobject()
handle it.
The setting's verify() function already checks that the s390 options
are not empty and no longer than 200. Asserting for that is a major
annoyance, because callers need to reimplement that check.
Instead of having a trivial macro that defines a function, define the
function directly.
Having such a macro would make sense if DEFINE_REMOVER_OPTION() would do
the right thing and we would reuse the (preferred) implementation.
That's not the case, because these remove_fcn() implementations don't
mirror the way how set_fcn() splits and sets options. They are
inconsistent (wrong), and should will later get merged with set_fcn().
Instead of using a macro to define the individual set/remove functions,
add a new property type _pt_multilist.
This way, we have more the concept of a property having a type, instead
of a property having a set of handlers how to implement something.
Also, this is only the first step. There are several similar properties
that also can be implemented as the same type.
The property implementation must itself decide how to reset a value.
We must not rely on properties being plain GObject properties.
Let set_fcn() accept %NULL value to indicate resetting the default.
Previously we had DEFINE_REMOVER_INDEX_OR_VALUE_DIRECT() and
DEFINE_REMOVER_INDEX_OR_VALUE_VALIDATING_STATIC().
Note that all property-infos of DEFINE_REMOVER_INDEX_OR_VALUE_VALIDATING_STATIC()
would also define values_static list, while DEFINE_REMOVER_INDEX_OR_VALUE_DIRECT()
would not.
Merge the two macros. The property-info should define how the
implementation behaves, we should not have two implementations.
set_fcn() of NM_SETTING_802_1X_EAP is implemented via
DEFINE_SETTER_STR_LIST_MULTI() -- thus, considering valid values
from the static list.
The remove_fcn() should do that too, to be consistent.
We don't need DEFINE_SETTER_STR_LIST_MULTI() to define a static function
that is called by the set_fcn() implementation. Instead, let the macro
define the actual set_fcn() function.
It's fundamentally wrong to have separate "remove_fcn" and "set_fcn"
implementations. Set, reset, add, and remove are all similar, and should
be implemented in a similar manner.
Merge the implementations all in set-property, which now can:
- reset the value (value == NULL && modifier == '\0')
- set a value (value != NULL && modifier == '\0')
- add a value (value != NULL && modifier == '+')
- remove a value (value != NULL && modifier == '-')
The real problem is that remove_fcn() behaves fundamentally different
from set_fcn(). You can do "+setting.property value1,value2" but you
cannot remove them the same way. That is because most remove_fcn()
implementations don't expect a list of values. But it's also because of
the unnatural split between set_fcn() and remove_fcn().
The next commit will merge set_fcn(), remove_fcn() and reset property.
This commit just merges them all in nmc_setting_set_property().
ipv4_method_changed_cb() and ipv6_method_changed_cb() are horrible hacks, as they
use a static variable to cache the previous value.
Anyway, don't fix that now.
We are going to drop nmc_property_get_gvalue()/nmc_property_set_gvalue()
because that works only with GObject based properties -- and having this
API around wrongly suggests it works in general. Use the native types
directly.
"reset" is just a special case of "set". We can keep nmc_setting_reset_property() as a convenience
function, but it must be implemented based on nmc_setting_set_property().
Also, reset only used nmc_property_set_default_value(), which only works
with GObject based properties. It's wrong to assume that all properties
are GObject based. By implementing it based via nmc_setting_set_property()
we can fix this (later).
