NMSetting internally already tracked a list of all proper GObject properties
and D-Bus-only properties.
Rework the tracking of the list, so that:
- instead of attaching the data to the GType of the setting via
g_type_set_qdata(), it is tracked in a static array indexed by
NMMetaSettingType. This allows to find the setting-data by simple
pointer arithmetic, instead of taking a look and iterating (like
g_type_set_qdata() does).
Note, that this is still thread safe, because the static table entry is
initialized in the class-init function with _nm_setting_class_commit().
And it only accessed by following a NMSettingClass instance, thus
the class constructor already ran (maybe not for all setting classes,
but for the particular one that we look up).
I think this makes initialization of the metadata simpler to
understand.
Previously, in a first phase each class would attach the metadata
to the GType as setting_property_overrides_quark(). Then during
nm_setting_class_ensure_properties() it would merge them and
set as setting_properties_quark(). Now, during the first phase,
we only incrementally build a properties_override GArray, which
we finally hand over during nm_setting_class_commit().
- sort the property infos by name and do binary search.
Also expose this meta data types as internal API in nm-setting-private.h.
While not accessed yet, it can prove beneficial, to have direct (internal)
access to these structures.
Also, rename NMSettingProperty to NMSettInfoProperty to use a distinct
naming scheme. We already have 40+ subclasses of NMSetting that are called
NMSetting*. Likewise, NMMetaSetting* is heavily used already. So, choose a
new, distinct name.
Previously, each (non abstract) NMSetting class had to register
its name and priority via _nm_register_setting().
Note, that libnm-core.la already links against "nm-meta-setting.c",
which also redundantly keeps track of the settings name and gtype
as well.
Re-use NMMetaSettingInfo also in libnm-core.la, to track this meta
data.
The goal is to get rid of private data structures that track
meta data about NMSetting classes. In this case, "registered_settings"
hash. Instead, we should have one place where all this meta data
is tracked. This was, it is also accessible as internal API,
which can be useful (for keyfile).
Note that NMSettingClass has some overlap with NMMetaSettingInfo.
One difference is, that NMMetaSettingInfo is const, while NMSettingClass
is only initialized during the class_init() method. Appart from that,
it's mostly a matter of taste, whether we attach meta data to
NMSettingClass, to NMMetaSettingInfo, or to a static-array indexed
by NMMetaSettingType.
Note, that previously, _nm_register_setting() was private API. That
means, no user could subclass a functioning NMSetting instance. The same
is still true: NMMetaSettingInfo is internal API and users cannot access
it to create their own NMSetting subclasses. But that is almost desired.
libnm is not designed, to be extensible via subclassing, nor is it
clear why that would be a useful thing to do. One day, we should remove
the NMSetting and NMSettingClass definitions from public headers. Their
only use is subclassing the types, which however does not work.
While libnm-core was linking already against nm-meta-setting.c,
nm_meta_setting_infos was unreferenced. So, this change increases
the binary size of libnm and NetworkManager (1032 bytes). Note however
that roughly the same information was previously allocated at runtime.
- Don't use @parent_class name. This local variable (and @object_class) is
the class instance up-cast to the pointer types of the parents. The point
here is not that it is the direct parent. The point is, that it's the
NMSettingClass type.
Also, it can only be used inconsistently, in face of NMSettingIP4Config,
who's parent type is NMSettingIPConfig. Clearly, inside
nm-setting-ip4-config.c we wouldn't want to use the "parent_class"
name. Consistently rename @parent_class to @setting_class.
- Also rename the pointer to the own class to @klass. "setting_class" is also the
wrong name for that, because the right name would be something like
"setting_6lowpan_class".
However, "klass" is preferred over the latter, because we commonly create new
GObject implementations by copying an existing one. Generic names like "klass"
and "self" inside a type implementation make that simpler.
- drop useless comments like
/* virtual functions */
/* Properties */
It's better to logically and visually structure the code, and avoid trival
remarks about that. They only end up being used inconsistently. If you
even need a stronger visual separator, then an 80 char /****/ line
should be preferred.
constructor functions are ugly, because code is running before
main() starts. Instead, as the registration code for NMSetting types
is insid the GType constructor, we just need to ensure at the
right place, that the GType was created.
The right place here is _register_settings_ensure_inited(), because
that is called before we need the registration information.
We'll need two "base" settings for Bluetooth NAP connections: bridge to set up
the actual link and bluetooth to identify the HCI to register the network
server with.
Let's use two priorities for base setting, with "1" marking one of higher
priority and "2" of lower priority when both are present.
priv->path_cost and priv->priority can only be set as GObject properties,
which already does the same range check. Hence, the checks are never reached.
This also avoids a compiler warning:
libnm-core/nm-setting-bridge-port.c: In function ‘verify’:
libnm-core/nm-setting-bridge-port.c:132:22: error: comparison is always false due to limited range of data type [-Werror=type-limits]

- All internal source files (except "examples", which are not internal)
should include "config.h" first. As also all internal source
files should include "nm-default.h", let "config.h" be included
by "nm-default.h" and include "nm-default.h" as first in every
source file.
We already wanted to include "nm-default.h" before other headers
because it might contains some fixes (like "nm-glib.h" compatibility)
that is required first.
- After including "nm-default.h", we optinally allow for including the
corresponding header file for the source file at hand. The idea
is to ensure that each header file is self contained.
- Don't include "config.h" or "nm-default.h" in any header file
(except "nm-sd-adapt.h"). Public headers anyway must not include
these headers, and internal headers are never included after
"nm-default.h", as of the first previous point.
- Include all internal headers with quotes instead of angle brackets.
In practice it doesn't matter, because in our public headers we must
include other headers with angle brackets. As we use our public
headers also to compile our interal source files, effectively the
result must be the same. Still do it for consistency.
- Except for <config.h> itself. Include it with angle brackets as suggested by
https://www.gnu.org/software/autoconf/manual/autoconf.html#Configuration-Headers
The localization headers are now included via "nm-default.h".
Also fixes several places, where we wrongly included <glib/gi18n-lib.h>
instead of <glib/gi18n.h>. For example under "clients/" directory.
Move the settings/plugins doc generation from libnm-util to
libnm-core, since libnm-util isn't being updated for all new
properties.
With this commit, the keyfile and ifcfg-rh documentation is basically
unchanged, except that deprecated properties are now gone, and new
properties have been added, and the sections are in a different order.
(generate-plugin-docs.pl just outputs the settings in Makefile order,
and they were unsorted in libnm-util, but are sorted in libnm-core).
The settings documentation used for nm-settings.5, the D-Bus API docs,
and the nmcli help is changed a bit more at this point, and mostly for
the worse, since the libnm-core setting properties don't match up with
the D-Bus API as well as the libnm-util ones do. To be fixed...
(I also removed the "plugins docs" line in each plugin docs comment
block while moving them, since those blocks will be used for more than
just plugins soon, and it's sort of obvious anyway.)
Libraries need to include <gi18n-lib.h>, not <gi18n.h>, so that _()
will get defined to "dgettext (GETTEXT_DOMAIN, string)" rather than
"gettext (string)" (which will use the program's default domain, which
works fine for programs in the NetworkManager tree, but not for
external users). Likewise, we need to call bindtextdomain() so that
gettext can find the translations if the library is installed in a
different prefix from the program using it (and
bind_textdomain_codeset(), so it will know the translations are in
UTF-8 even if the locale isn't).
(The fact that no one noticed this was broken before is because the
libraries didn't really start returning useful translated strings much
until 0.9.10, and none of the out-of-tree clients have been updated to
actually show those strings to users yet.)
config.h should be included from every .c file, and it should be
included before any other include. Fix that.
(As a side effect of how I did this, this also changes us to
consistently use "config.h" rather than <config.h>. To the extent that
it matters [which is not much], quotes are more correct anyway, since
we're talking about a file in our own build tree, not a system
include.)
nm_setting_verify() took a GSList of other NMSettings, but really it
would just be simpler all around to pass the NMConnection instead...
This means that several formerly NMSetting-branded functions that
operated on lists-of-settings now get replaced with
NMConnection-branded functions instead.
Add nm-core-types.h, typedefing all of the GObject types in
libnm-core; this is needed so that nm-setting.h can reference
NMConnection in addition to nm-connection.h referencing NMSetting.
Removing the cross-includes from the various headers causes lots of
fallout elsewhere. (In particular, nm-utils.h used to include
nm-connection.h, which included every setting header, so any file that
included nm-utils.h automatically got most of the rest of libnm-core
without needing to pay attention to specifics.) Fix this up by
including nm-core-internal.h from those files that are now missing
includes.
Each setting type was defining its own error type, but most of them
had exactly the same three errors ("unknown", "missing property", and
"invalid property"), and none of the other values was of much use
programmatically anyway.
So, this commit merges NMSettingError, NMSettingAdslError, etc, all
into NMConnectionError. (The reason for merging into NMConnectionError
rather than NMSettingError is that we also already have
"NMSettingsError", for errors related to the settings service, so
"NMConnectionError" is a less-confusable name for settings/connection
errors than "NMSettingError".)
Also, make sure that all of the affected error messages are localized,
and (where appropriate) prefix them with the relevant property name.
Renamed error codes:
NM_SETTING_ERROR_PROPERTY_NOT_FOUND -> NM_CONNECTION_ERROR_PROPERTY_NOT_FOUND
NM_SETTING_ERROR_PROPERTY_NOT_SECRET -> NM_CONNECTION_ERROR_PROPERTY_NOT_SECRET
Remapped error codes:
NM_SETTING_*_ERROR_MISSING_PROPERTY -> NM_CONNECTION_ERROR_MISSING_PROPERTY
NM_SETTING_*_ERROR_INVALID_PROPERTY -> NM_CONNECTION_ERROR_INVALID_PROPERTY
NM_SETTING_ERROR_PROPERTY_TYPE_MISMATCH -> NM_CONNECTION_ERROR_INVALID_PROPERTY
NM_SETTING_BLUETOOTH_ERROR_TYPE_SETTING_NOT_FOUND -> NM_CONNECTION_ERROR_INVALID_SETTING
NM_SETTING_BOND_ERROR_INVALID_OPTION -> NM_CONNECTION_ERROR_INVALID_PROPERTY
NM_SETTING_BOND_ERROR_MISSING_OPTION -> NM_CONNECTION_ERROR_MISSING_PROPERTY
NM_SETTING_CONNECTION_ERROR_TYPE_SETTING_NOT_FOUND -> NM_CONNECTION_ERROR_MISSING_SETTING
NM_SETTING_CONNECTION_ERROR_SLAVE_SETTING_NOT_FOUND -> NM_CONNECTION_ERROR_MISSING_SETTING
NM_SETTING_IP4_CONFIG_ERROR_NOT_ALLOWED_FOR_METHOD -> NM_CONNECTION_ERROR_INVALID_PROPERTY
NM_SETTING_IP6_CONFIG_ERROR_NOT_ALLOWED_FOR_METHOD -> NM_CONNECTION_ERROR_INVALID_PROPERTY

NM_SETTING_WIRELESS_ERROR_CHANNEL_REQUIRES_BAND -> NM_CONNECTION_ERROR_MISSING_PROPERTY
Dropped error codes (were previously defined but unused):
NM_SETTING_CDMA_ERROR_MISSING_SERIAL_SETTING
NM_SETTING_CONNECTION_ERROR_IP_CONFIG_NOT_ALLOWED
NM_SETTING_GSM_ERROR_MISSING_SERIAL_SETTING
NM_SETTING_PPP_ERROR_REQUIRE_MPPE_NOT_ALLOWED

Rename NM_CONNECTION_ERROR_UNKNOWN to NM_CONNECTION_ERROR_FAILED,
following GError best practices.
Replace NM_CONNECTION_ERROR_CONNECTION_SETTING_NOT_FOUND ("no
NMSettingConnection") with a more generic
NM_CONNECTION_ERROR_MISSING_SETTING. Use that new code in a few places
that had previously been using NM_CONNECTION_ERROR_SETTING_NOT_FOUND,
which was supposed to mean "the setting that you asked about doesn't
exist", not "the connection is invalid because it's missing a required
setting".
Clarify that NM_CONNECTION_ERROR_INVALID_SETTING can be used for any
"invalid or inappropriate NMSetting", not just a "conflicting" one.
(But fix a case in nm_connection_update_secrets() that was returning
INVALID_SETTING when it should have been return-if-failing instead.)
For both MISSING_SETTING and INVALID_SETTING, always prefix the error
message with "setting-name: ", just like we do with the various
NMSetting MISSING_PROPERTY and INVALID_PROPERTY errors. And make sure
that the error message is marked for localization.
Drop NM_CONNECTION_ERROR_CONNECTION_TYPE_INVALID, which is pretty
pointless; it was only used in the case where connection.type was the
name of a valid setting type that is not a base setting type. Instead,
just return NM_SETTING_CONNECTION_ERROR_INVALID_PROPERTY for
connection.type in this case (which is what the code already did when
connection.type was completely unrecognized).
In preparation for porting to GDBus, make nm_connection_to_dbus(),
etc, represent connections as GVariants of type 'a{sa{sv}}' rather
than as GHashTables-of-GHashTables-of-GValues.
This means we're constantly converting back and forth internally, but
this is just a stepping stone on the way to the full GDBus port, and
all of that code will go away again later.
Simplify the use of _nm_register_setting() by having it splice
together various symbol names itself rather than requiring them to be
specified explicitly, and extend it to also ensure that the type's
corresponding error type is registered (allowing one to find it via
g_type_from_name() if necessary).
Some NMSettingConnection:slave-type types require a matching slave #NMSetting.
Add normalization of either the 'slave-type' property or the slave-setting.
Also be more strict in NMSettingConnection:verify() to enforce an
existing slave-setting depending on the slave-type.

Add NetworkManager.h, which includes all of the other NM header, and
require all external users of libnm to use that rather than the
individual headers.
(An exception is made for nm-dbus-interface.h,
nm-vpn-dbus-interface.h, and nm-version.h, which can be included
separately.)
This commit begins creating the new "libnm", which will replace
libnm-util and libnm-glib.
The main reason for the libnm-util/libnm-glib split is that the daemon
needs to link to libnm-util (to get NMSettings, NMConnection, etc),
but can't link to libnm-glib (because it uses many of the same type
names as the NetworkManager daemon. eg, NMDevice). So the daemon links
to only libnm-util, but basically all clients link to both.
With libnm, there will be only a single client-visible library, and
NetworkManager will internally link against a private "libnm-core"
containing the parts that used to be in libnm-util.
(The "libnm-core" parts still need to be in their own directory so
that the daemon can see those header files without also seeing the
ones in libnm/ that conflict with its own headers.)
