Use two common defines NM_BUILD_SRCDIR and NM_BUILD_BUILDDIR
for specifying the location of srcdir and builddir.
Note that this is only relevant for tests, as they expect
a certain layout of the directories, to find files that concern
them.
Tests are commonly created via copy&paste. Hence, it's
better to express a certain concept explicitly via a function
or macro. This way, the implementation of the concept can be
adjusted at one place, without requiring to change all the callers.
Also, the macro is shorter, and brevity is better for tests
so it's easier to understand what the test does. Without being
bothered by noise from the redundant information.
Also, the macro knows better which message to expect. For example,
messages inside "src" are prepended by nm-logging.c with a level
and a timestamp. The expect macro is aware of that and tests for it
#define NMTST_EXPECT_NM_ERROR(msg) NMTST_EXPECT_NM (G_LOG_LEVEL_MESSAGE, "*<error> [*] "msg)
This again allows the caller to ignore this prefix, but still assert
more strictly.
The "shared" directory contains files that are possibly used by all components
of NetworkManager repository.
Some of these files are even copied as-is to other projects (VPN plugins, nm-applet)
and used there without modification. Move those files to a separate directory.
By moving them to a common directory, it is clearer that they belong
together. Also, you can easier compare the copied versions to their
original via
$ diff -r ./shared/nm-utils/ /path/to/nm-vpn-plugin/shared/nm-utils/
A failure to g_return*() by default prints a g_critical() with stringifing the
condition. Add a macro NMTST_G_RETURN_MSG() that reproduces that line to more
accurately match the failure message.
The linking test causes a crash to check whether libnm and libnm-util
are both linked. If abrt or systemd-coredump are enabled, the core
dump processing will take a long time when the address sanitizer is
enabled, due to the huge process address space. It seems a good choice
to disable the test when NM was compiled with -fsanitize=address.
- 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
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.
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).
A failure to g_return_*() prints a critical warning which contains
G_STRFUNC. Depending on the compiler this contains only the function
name or the entire signature.
Relax the assertion pattern to check the function name.
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.)
test_libnm_linking() executes ./test-libnm-linking which
is supposed to crash. When the user set `ulimit -c unlimited`
before, this will leave a left-over core file.
In case of `make distcheck`, this is quite bad because it lets
the make target fail:
ERROR: files left in build directory after distclean:
./libnm-util/tests/core.31481
Fix this by setting the (soft) rlimit for writing core files
to 0 before executing the test binary.

Since libnm-util is no longer used from within NM, its copy of
NM_UTIL_PRIVATE_CALL is now useless, and the internal-only
NMSettingIP4Config:address-labels property is no longer needed.
- 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.
Some type-specific NMSetting implementations (bond, bridge, team, vlan)
have their own 'interface-name' property. This property will be
deprecated in favour of 'interface-name' in NMSettingConnection.
Change verify() and normalize() to check that the redundant
values match and repair/normalize the properties.
Force the virtual interface name of the type-specific setting to be
equal to NMSettingConnection:interface_name. This way, the depreacted
field stays valid and backward compatible.
NMSettingInfiniband is special, because it does not have a backing
property for the interface name, although it implements
get_virtual_iface_name(). To account for this, some special handling
is needed in order not to change the behaviour of get_virtual_iface_name().

Some tests want to assert against the messages logged using g_test_expect_message().
In this mode, nmtst will not log anything itself.
Interpret the option no-expect-message which turns g_test_expect_message()
into a NOP and turns logging on. The use of this is for debugging such
tests, without asserting against the messages but printing them instead.
For tests that are not in the assert_message mode, the option has no
effect.
Example:
NMTST_DEBUG=debug,no-expect-message make -C src/settings/plugins/keyfile/tests/ check

Commit 240c92ddb5 added an assert
to check that the input netmask is valid. Revert that commit for
the most part, some changes to the test function are not reverted.
We don't want to assert for a valid netmask, because it's
common to read the netmask from (untrusted) user input, so we
don't want to assert against it.
The caller *could* validate the netmask from untrusted sources, but
with the assert in place it cannot validate it in the most obvious way:
prefix = nm_utils_ip4_netmask_to_prefix (netmask);
if (netmask != nm_utils_ip4_prefix_to_netmask (prefix))
goto fail;

INFERRABLE means the opposite of CANDIDATE; a property which NetworkManager
can read ("infer") from the system or the kernel when generating
connections. CANDIDATE isn't a great name and thus dies.
Old versions such as 0.9.4 generated 40-character UUIDs with no
hashes, but libnm-util regards them as invalid. That means that
existing connections stop working when upgrading from 0.9.4.
Continue accepting such UUIDs as valid, and add a test so that
we don't forget in future.
Convenience function to replace settings in one conneciton with settings
from another, without having to go through the nm_connection_to_hash()
steps, which are just inefficient and kinda pointless.
