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.
Not all implementations support having the value being an index.
For example, the implementations that are done via DEFINE_REMOVER_OPTION() macro.
The meaning of the "value" string must not be determined by
nmc_setting_remove_property_option(). It's up to the implementation
to decide whether to allow an index and how to interpret it.
$ nmcli connection add type vlan autoconnect no con-name v dev vlan.1 id 1
$ nmcli connection modify v +vlan.ingress-priority-map 1:2,2:3
$ nmcli connection modify v +vlan.ingress-priority-map 2:3,4:5
$ nmcli connection modify v -vlan.ingress-priority-map 1:2,4:5
Warning: only one mapping at a time is supported; taking the first one (1:2)
Part 1, which addresses the issue for simple properties that have
a plain remove-by-value function.
Rationale:
Removing a value/index that does not exist should not be a failure.
Woule you like:
$ nmcli connection modify "$PROFILE" autoconnect no
$ nmcli connection modify "$PROFILE" autoconnect no
Error: autoconnect is already disabled
So, why would it be a good idea to fail during
$ nmcli connection modify "$PROFILE" -vpn.data ca
$ nmcli connection modify "$PROFILE" -vpn.data ca
Error: failed to remove a value from vpn.data: invalid option 'ca'.
Generally, it should not be an error to remove an option, as long
as the option itself is valid. For example,
$ nmcli connection modify "$PROFILE" -vlan.ingress-priority-map bogus
should fail, but
$ nmcli connection modify "$PROFILE" -vlan.ingress-priority-map 1:5
should succeed even if there was nothing to remove.
The "from" part is like a key for the egress/ingress priority map.
Extend nm_setting_vlan_remove_priority_str_by_value() to accept only the
"from" part when finding and deleting value. This allows for:
$ nmcli connection modify "$PROFILE" -vlan.ingress-priority-map '4:'
$ nmcli connection modify "$PROFILE" -vlan.ingress-priority-map '4:*'
to fuzzy match the value to remove.
How hard can it be to use strtol()? Apparently very. You need to check
errno, the endpointer, and also not pass in an empty string.
Previously, nmc_string_to_uint_base() would silently accept "" as valid
number. That's a bug.
Btw, let's not use strtol() (or nmc_string_to_uint*()). We have
_nm_utils_ascii_str_to_int64(), which gets all of this right.
We have code in "shared/nm-utils" which are general purpose
helpers, independent of "libnm", "libnm-core", "clients" and "src".
We have shared code like "shared/nm-ethtool-utils.h" and
"shared/nm-meta-setting.h", which is statically linked, shared
code that contains libnm related helpers. But these helpers already
have a specific use (e.g. they are related to ethtool or NMSetting
metadata).
Add a general purpose helper that:
- depends (and extends) libnm-core
- contains unrelated helpers
- can be shared (meaning it will be statically linked).
- this code can be used by any library user of "libnm.so"
(nmcli, nm-applet) and by "libnm-core" itself. Thus, "src/"
and "libnm/" may also use this code indirectly, via "libnm-core/".
Support importing ".conf" files as `wg-quick up` supports it.
`wg-quick` parses several options under "[Interface]" and
passes the remainder to `wg setconf`.
The PreUp/PreDown/PostUp/PostDown options are of course not supported.
"Table" for the moment behaves different.
