This fixes test-failure for src/platform/tests/test-link-fake on older
systems.

Having a static string buffer for convenience is useful not only
for platform. Define the string buffer in NetworkManagerUtils.h,
so that all to-string functions can reuse *one* buffer.
Of course, this has the potential danger, that different
to-string method might reuse the same buffer. Hence, low-level
library functions are adviced to use their own buffer, because
an upper level might already use the global buffer for another
string.
|
|
Arguably, it is more convenient to use the static buffer as
it saves typing.
But having such a low-level function use a static buffer also
limits the way how to use it. As it was, you could not avoid
using the static buffer.
E.g. you cannot do:
char buf[100];
_LOGD ("nmp-object: %s; platform-link: %s",
nmp_object_to_string (nmpobj, buf, sizeof(buf)),
nm_platform_link_to_string (link));
This will fail for non-obvious reasons because both
to-string functions end up using the same static buffer.
Also change the to-string implementations to accept NULL
as valid and return it as "(null)".

It is valid to call nm_clear_g_signal_handler() with missing
@self argument if (and only if) the @id is unspecified as well.
Remove the check for @self to get an assertion in case @id
is missing *and* @self is invalid. In this case,
g_signal_handler_disconnect() will raise a g_critical() for us.

It does not make sense to issue an error. This should be a helper function.
"NetworkManager[18341]: nm_clear_g_signal_handler: assertion 'G_IS_OBJECT (self)' failed"
error started since commit e6d7fee5a617632acae02e12b1ec6156842df788 due to that.

Support a new configuration option
[.config]
enable=<ENABLED>
for configuration snippets.
This new [.config] section is only relevant within the snippet itself
and it is not merged into the combined configuration.
Currently only the "enable" key is supported. If the "enable" key is
missing, it obviously defaults to being enabled. It allows snippets
to be skipped from loading. The main configuration "NetworkManager.conf"
cannot be skipped.
<ENABLED> can be a boolean value (false), to skip a configuration
snippet from loading.
It can also be a string to match against the NetworkManager version,
like "enable=nm-version-min:1.1,nm-version-min:1.0.6"
There are several motivations for this:
- the user can disable an entire configuration snippet by toggeling
one entry.
This generalizes the functionality of the global-dns.enable
setting, but in a way that applies to configuration on a per-file
basis.
- for developing, we often switch between different versions of
NetworkManager. Thus, we might want to use different configuration.
E.g. before global-dns options, I want to use "dns=none" and manage
resolv.conf myself. Now, I can use global-dns setting to do that.
That can be achieved with something like the following (not exactly,
it's an example only):
[.config]
enable=nm-version-min:1.1
[main]
dns=default
[global-dns-domain-*]
nameserver=127.0.0.1
Arguably, this would be more awesome, if we would bump our micro devel
version (1.1.0) more often while developing 1.2.0 (*hint*).
- in principle, packages could drop configuration snippets and enable
them based on the NetworkManager version.
- with the "env:" spec, you can enable/disable snippets by configuring
an environment variable. Again, useful for testing and developing.

Allows to enable more-asserts more granularly.
Unfortunately, the old check was "${enable_more_asserts} == "yes", thus
we cannot extend "--enable-more-assert=level" because that would mean
that the same build script cannot set the option on both old and new
NetworkManager.
Thus, add a new option --with-more-asserts=level. If you put the
following in your build script, it will work as expected whether
you build a new or an old version of NetworkManager.
./configure --enable-more-asserts --with-more-asserts=5

"nm-version-macros.h"
For libnm library, "nm-dbus-interface.h" contains defines like the D-Bus
paths of NetworkManager. It is desirable to have this header usable without
having a dependency on "glib.h", for example for a QT application. For that,
commit c0852964a890cf43cc2dcaeff41ac6edc5028f24 removed that dependancy.
For libnm-glib library, the analog to "nm-dbus-interface.h" is
"NetworkManager.h", and the same applies there. Commit
159e827a72f420048e12d318f8ba1edd3f641fc8 removed that include.
However, that broke build on PackageKit [1] which expected to get the
version macros by including "NetworkManager.h". So at least for libnm-glib,
we need to preserve old behavior so that a user including
"NetworkManager.h" gets the version macros, but not "glib.h".
Extract the version macros to a new header file "nm-version-macros.h".
This header doesn't include "glib.h" and can be included from
"NetworkManager.h". This gives as previous behavior and a glib-free
include.
For libnm we still don't include "nm-version-macros.h" to "nm-dbus-interface.h".
Very few users will actually need the version macros, but not using
libnm.
Users that use libnm, should just include (libnm's) "NetworkManager.h" to
get all headers.
As a special case, a user who doesn't want to use glib/libnm, but still
needs both "nm-dbus-interface.h" and "nm-version-macros.h", can include
them both separately.

All current users of NM_IN_SET() would rather use short-circuit evalation
(or don't care). It seems that doing it by default seems favorable.
The only downside is, that this might have somewhat unexpected behavior
to a user who expects a regular function (which would evaluate always
all arguments).

Let the preprocessor do more work, but generate a simple expression that
the compiler can optimize (presumably) better.

Port remaining bits to gdbus and remove stray dbus-glib references
Drop the dbus-glib version check from configure, since nothing depends
on new dbus-glib any more.
Move nm-dbus-glib-types.h and nm-gvaluearray-compat.h from include/ to
libnm-util/ since they are now only used by libnm-util and libnm-glib.
|

Also remove some now-unused NMBusManager API

This internal header file should be included by our internal source
code files and header files. It includes in one place other headers
that constitute to a minimal set of required headers. Most notably
this is <glib.h> and our "nm-glib.h" header.
Note that public header files and example source code cannot include
this file as "nm-default.h" is internal only.
|
|
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.

NM_DEFINE_SINGLETON is used only by core and makes use of nm-logging.
It does not belong to "include/nm-macros-internal.h". Move it to "src/".

Add a macro to insert the necessary compiler/linker magic to add a
copy of an existing symbol to an older version. Also, update
check-exports.sh to be able to check for such symbols by listed them
commented-out in the appropriate section.

The newer version of g_hash_table_replace() is useful, because it
