This speeds up the initial object tree load significantly. Also, it
reduces the object management complexity by shifting the duties to
GDBusObjectManager.
The lifetime of all NMObjects is now managed by the NMClient via the
object manager. The NMClient creates the NMObjects for GDBus objects,
triggers the initialization and serves as an object registry (replaces
the nm-cache).
The ObjectManager uses the o.fd.DBus.ObjectManager API to learn of the
object creation, removal and property changes. It takes care of the
property changes so that we don't have to and lets us always see a
consistent object state. Thus at the time we learn of a new object we
already know its properties.
The NMObject unfortunately can't be made synchronously initializable as
the NMRemoteConnection's settings are not managed with standard
o.fd.DBus Properties and ObjectManager APIs and thus are not known to
the ObjectManager. Thus most of the asynchronous object property
changing code in nm-object.c is preserved. The objects notify the
properties that reference them of their initialization in from their
init_finish() methods, thus the asynchronously created objects are not
allowed to fail creation (or the dependees would wait forever). Not a
problem -- if a connection can't get its Settings, it's either invisible
or being removed (presumably we'd learn of the removal from the object
manager soon).
The NMObjects can't be created by the object manager itself, since we
can't determine the resulting object type in proxy_type() yet (we can't
tell from the name and can't access the interface list). Therefore the
GDBusObject is coupled with a NMObject later on.
Lastly, now that all the objects are managed by the object manager, the
NMRemoteSettings and NMManager go away when the daemon is stopped. The
complexity of dealing with calls to NMClient that would require any of
the resources that these objects manage (connection or device lists,
etc.) had to be moved to NMClient. The bright side is that his allows
for removal all of the daemon presence tracking from NMObject.
We'll soon not only do the router discovery, but announce ourselves as a
reouter. "Neighbor discovery" sounds to be a more appropriate name for
the class than "Router discovery".
This is especially important because we don't support
line continuation. Thus, with
FOO='val
bar=3'
wrong line
F2=b
F3='b
XXX=adf'
XXX2=val2
'
we now write
FOO=
#NM: FOO='val
bar=
#NM: bar=3'
#NM: wrong line
F2=b
F3=
#NM: F3='b
XXX=
#NM: XXX=adf'
XXX2=val2
#NM: '
Basically, the writer will comment out any line that is
- not all-whitespace
- not a '#' comment (possibly proceeded by whitespace)
- not a valid variable assignment
This avoids that writer writes lines that are not understood by
ifcfg-rh plugin, but interferes with initscripts. E.g.
NAME=old-name'
rm -rf /
'
becomes
NAME=new-name
#NM: rm -rf /
#NM: '

NetworkManager and nm-iface-helper compiled nm-dhcp-manager.c twice,
the latter with setting -DNM_DHCP_INTERNAL_ONLY to only enable the
internal plugin.
Change that to compile nm-dhcp-manager.c once for both users
by putting it into libNetworkManagerBase.
We only needed proper glib enum types for having properties
and signal arguments. These got all converted to plain int,
so no longer generate such an enum type.
There is an strange automake warning
Makefile.vapigen:49: warning: $(1) was already defined in condition TRUE, which includes condition ENABLE_VAPIGEN ...
Makefile.am:4: 'Makefile.vapigen' included from here
Makefile.glib:124: ... '$(1)' previously defined here
Makefile.am:1: 'Makefile.glib' included from here
when having
if ENABLE_VAPIGEN
include Makefile.vapigen
endif
That is worked around by removing the "if", which however
requires us to remove the error check in Makefile.vapigen.
