GError codes are only unique per domain, so logging the code without
also indicating the domain is not helpful. And anyway, if the error
messages are not distinctive enough to tell the whole story then we
should fix the error messages.
Based-on-patch-by: Dan Winship <danw@gnome.org>
Use g_error_matches() where we're testing error codes. In particular,
use it rather than looking at only ->code and not also ->domain, which
is just wrong.
[thaller@redhat.com: rebase and modify original patch]
- 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
Rather than randomly including one or more of <glib.h>,
<glib-object.h>, and <gio/gio.h> everywhere (and forgetting to include
"nm-glib-compat.h" most of the time), rename nm-glib-compat.h to
nm-glib.h, include <gio/gio.h> from there, and then change all .c
files in NM to include "nm-glib.h" rather than including the glib
headers directly.
(Public headers files still have to include the real glib headers,
since nm-glib.h isn't installed...)
Also, remove glib includes from header files that are already
including a base object header file (which must itself already include
the glib headers).
Add a file containing the defines like DBUS_INTERFACE_DBUS from
dbus-shared.h, and use it from the gdbus-using files.
Also, convert a bunch of other places that were previously hardcoding
the string values to use the defines instead, and fix the ifcfg-rh
plugin to properly namespace its own D-Bus-related defines.
NMRemoteSettings queues a bunch of async NMRemoteConnection creations,
but wasn't doing anything to ensure that it was still alive when they
completed. Pointed out by Cosimo Cecchi.

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.)
When using a private bus connection, the service is never marked
as running when settings are initialized asynchronously. Successfully
opening a socket in NM's runtime directory should already imply
a running service, so just mark it as such (as we already do in
the synchronous path).
Some libnm-glib object properties were only documented in the
GParamSpec strings, not via gtk-doc comments, so they became
undocumented when the paramspec strings went away. Fix that.
(Also fix incorrect gtk-doc syntax with several NMClient properties.)
- Remove list of authors from files that had them; these serve no
purpose except to quickly get out of date (and were only used in
libnm-util and not libnm-glib anyway).
- Just say "Copyright", not "(C) Copyright" or "Copyright (C)"
- Put copyright statement after the license, not before
- Remove "NetworkManager - Network link manager" from the few files
that contained it, and "libnm_glib -- Access network status &
information from glib applications" from the many files that
contained it.
- Remove vim modeline from nm-device-olpc-mesh.[ch], add emacs modeline
to files that were missing it.
g-i allows you to specify types in annotations using either their
fully-qualified introspected names (eg, "NMClient.Device") or their
plain C names ("NMDevice"). Switch from the former to the latter (so
that they'll still be correct when migrated to libnm later).
Remove all remaining GParamSpec name and blurb strings (and fix
indentation while we're there), and add G_PARAM_STATIC_STRINGS to all
paramspecs that were lacking it.

Add a "monitor-connection-files" config option, which can be set to
"false" to disable automatic reloading of connections on file change.
To go with this, add a new ReloadConnections method on
o.fd.NM.Settings that can be used to manually reload connections, and
add an nm-cli command to call it.
Though the client shouldn't be calling anything when NM isn't running
(because clients have nm_client_get_manager_running()), make sure
that NMClient never calls a NetworkManager method when NM isn't
on the bus.
Next, ensure NMObject doesn't try to refresh properties when NM isn't
running. Creating an NMClient may trigger a property refresh request,
but if NM isn't running, defer that until NM starts, to ensure that
we don't D-Bus autostart NM.
Third, ensure NMRemoteSettings doesn't attempt to list connections
unless NM is running.
This prevents service activation of NetworkManager in lieu of dbus-glib
learning about DBUS_HEADER_FLAG_NO_AUTO_START.
Use the D-Bus connection helper whenever we need a connection to
NM, which by default tries to use a private connection instead of
the shared bus connection whenever the user is root. Doing this
by default will not change the behavior of libnm-glib, and allows
tools like nmcli and libnm-glib-using clients to work in minimal
environments (those without a bus daemon) by default.
When using a private connection, we need to use dbus_g_proxy_new_for_peer()
because the bus isn't involved. Since many parts of libnm-glib create a
proxy for their corresponding remote object, consolidate the proxy creation
logic.
A later patch will add logic to use a private connection versus a bus-based
one.
If async GetProperties completed before the GetConnections, init_left would
be 0 and thus we never connected to connections-read, causing us to terminate
initialization before connections were actually read.

If a class implements init_async, it should implement init_finish too,
rather than assuming the default implementation will do the right
thing (which it briefly didn't in glib 2.33).
In some situations, objects might get used after being disposed, so
clear out their various priv fields so we don't try to access unreffed
objects, freed strings, etc.
https://bugzilla.gnome.org/show_bug.cgi?id=674473
If a client keeps the connection around after NMRemoteSettings is done
with it (and has emitted 'removed' for that connection) then the
RemoteSettings object was still registered to receive signals for
that connection. To prevent clients from being able to screw up
the RemoteSettings, disconnect any signals it may be listening for
when the connection is removed. (it should be doing that anyway)
This reverts commit dd0460697c.
The commit dd0460697c make nm_remote_settings_new()
create the NMRemoteSettings object synchronously. It fixed getting properties,
but undid the previous ability to initialize the object asynchronously.
It can be reverted now, because a4f450aa0b commit
ensure initialization in get_property() calls.
We need to do _nm_object_ensure_inited() /
_nm_remote_settings_ensure_inited() from the get_property()
implementations; in most cases, get_property() just calls another
accessor method (which will call _nm_object_ensure_inited()), but in a
few places, it reads priv->whatever directly, so we need to make sure
that it's valid.
Bindings (like GObject Introspection) almost always create objects
using g_object_new() by default and don't use our helper functions
like nm_client_new(). Thus we need to make sure that if the
object is created in that way, any property accesses or functions
that return properties ensure that the object is fully initialized,
which is what the _new() functions were supposed to do. In one
case in NMClient that was missing (getting active connections)
and wasn't happening at all in NMRemoteSettings, which are our two
entry points into libnm-glib.
This allows this python+GI sequence to return the expected active
connection list:
from gi.repository import NMClient
nmclient = NMClient.Client(dbus_path='/org/freedesktop/NetworkManager')
active = nmclient.get_active_connections()
print(active)
where previously it returned an empty list because the NMClient
wasn't fully initialized by the time nm_client_get_active_connections()
was called.
Rather than generating enum classes by hand (and complaining in each
file that "this should really be standard"), use glib-mkenums.
Unfortunately, we need a very new version of glib-mkenums in order to
deal with NM's naming conventions and to fix a few other bugs, so just
import that into the source tree temporarily.
Also, to simplify the use of glib-mkenums, import Makefile.glib from
https://bugzilla.gnome.org/654395.
To avoid having to run glib-mkenums for every subdirectory of src/,
add a new "generated" directory, and put the generated enums files
there.
Finally, use Makefile.glib for marshallers too, and generate separate
ones for libnm-glib and NetworkManager.
Implement GInitable and GAsyncInitable in NMObject, with
implementations that synchronously or asynchonously load all
properties, and change _nm_object_ensure_inited() to run
g_initable_init().
Update the object/object-array property handling to initialize the
objects after creating them (synchronously or asynchronously,
according to the situation), so that they will have all of their
properties preloaded before they are ever visible to the caller.
Move the non-blocking/non-failable parts of various objects'
constructor() methods to constructed(), and move the blocking/failable
parts to init(), and implement init_async() methods with non-blocking
versions of the blocking methods.
Make nm_device_new() and nm_client_new() call
_nm_object_ensure_inited(), to preserve the behaviour formerly
enforced by their construct() methods, that properties are guaranteed
to be initialized before any signals involving them are emitted.
Most of the code was using dbus_g_proxy_call() directly, but there
were some leftover uses of the generated bindings. Make things more
consistent by using dbus_g_proxy_call() everywhere, and stop building
the -bindings.h files.
