"active_slave" option is a deprecated alias for "primary". nmtui can configure
the "primary" option, so whenever it configures a profile the "active_slave"
option should be unset.
When configuring miimon settings, the updelay/downdelay fields with
value zero may not be stored in the setting.
For example:
- have a profile with "mode=balance-rr,arp_interval=11,arp_ip_target=10.10.10.1,miimon=10"
Switch the link monitoring mode to "MII" and press <OK>. Previously,
the change of the link monitoring did not update the settings, and
nothing was changed.
- when loading settings, initialize all fields with the values from the
settings, regardless whether they are currently visible or not.
Otherwise, if you edit a profile with
"mode=balance-rr,arp_interval=11,arp_ip_target=10.10.10.1,miimon=10"
and switch link monitoring mode to "MII", the miimon setting was not
initialized to 10.
- accept empty bond settings, for example for updelay. In that case,
initialize the text input to "0". Likewise, when the text entry is
empty, set the bond option to the respective default.

When a failure occurs on deactivation of a connection, no error was
shown on the TUI client. It was not obvious if anything was actually
happening after pressing the <Deactivate> button.
This patch shows the error in a dialog just like we do when a failure
occurs on activation of a connection.

g_clear_pointer() would always cast the destroy notify function
pointer to GDestroyNotify. That means, it lost some type safety, like
GPtrArray *ptr_arr = ...
g_clear_pointer (&ptr_arr, g_array_unref);
Since glib 2.58 ([1]), g_clear_pointer() is also more type safe. But
this is not used by NetworkManager, because we don't set
GLIB_VERSION_MIN_REQUIRED to 2.58.

We have nm_clear_pointer() to avoid this issue for a long time (pre
1.12.0). Possibly we should redefine in our source tree g_clear_pointer()
as nm_clear_pointer(). However, I don't like to patch glib functions
with our own variant. Arguably, we do patch g_clear_error() in
such a manner. But there the point is to make the function inlinable.
Also, nm_clear_pointer() returns a boolean that indicates whether
anything was cleared. That is sometimes useful. I think we should
just consistently use nm_clear_pointer() instead, which does always
the preferable thing.
Replace:
sed 's/\<g_clear_pointer *(\([^;]*\), *\([a-z_A-Z0-9]\+\) *)/nm_clear_pointer (\1, \2)/g' $(git grep -l g_clear_pointer) -i
I think it's preferable to use nm_clear_g_free() instead of
g_clear_pointer(, g_free). The reasons are not very strong,
but I think it is overall preferable to have a shorthand for this
frequently used functionality.
sed 's/\<g_clear_pointer *(\([^;]*\), *\(g_free\) *)/nm_clear_g_free (\1)/g' $(git grep -l g_clear_pointer) -i
When creating a new connection before the user gets the chance to modify
the bond options let's just initialize 'mode' and 'miimon' (with related
'updelay' and 'downdelay').
Initializing also 'arp_interval', 'arp_ip_target' and 'primary' doesn't
make much sense as by default they're disabled or contain empty values.
nm_utils_is_valid_iface_name() is a public API of libnm-core, let's use
our internal API.
$ sed -i 's/\<nm_utils_is_valid_iface_name\>/nm_utils_ifname_valid_kernel/g' $(git grep -l nm_utils_is_valid_iface_name)
We should use the same "is-valid" function everywhere.
Since nm_utils_ipaddr_valid() is part of libnm, it does not qualify.
Use nm_utils_ipaddr_is_valid() instead.
Using sync init (nm_client_new()) has an overhead as it requires an internal
GMainContext to ensure preserving the order of D-Bus messages. Let's avoid
that by using the async init. Note that the difference here is that we will
iterate the caller's GMainContext while creating the instance. But that
is no problem for nmtui at that point.
The dependencies used in the build of the `nmtui` executable and the
`libnmt-newt` library have been reviewed.
The compiler flags used in common by them has also been moved to a
`common_c_flags` variable to avoid any confussion.
The variable holding the compiler flags, `cflags`, has been renamed
to `c_flags` to be consistent with the rest of build files.
Different objects used in the `test-dispatcher-envp` target
have been grouped together.
The dependency over the `libnm` library has been removed as it is
unnecessary.
The targets that involve the use of the `libnm` library have been
improved by applying a set of changes:
- Generated enum sources variable `libnm_enum` has been renamed to
`libnm_enum_sources` to clearly specify what it is holding.
- Indentation in the `libnm` build and test files has been fixed.
- Set of objects used in targets have been grouped together.
The `libnm-core` build file has been improved by applying a set of
changes:
- Indentation has been fixed to be consistent.
- Library variable names have been changed to `lib{name}` pattern
following their filename pattern.
- `shared` prefix has been removed from all variables using it.
- Dependencies have been reviewed to store the necessary data.
- The use of the libraries and dependencies created in this file
has been reviewed through the entire source code. This has
required the addition or the removal of different libraries and
dependencies in different targets.
- Some files used directly with the `files` function have been moved
to their nearest path build file because meson stores their full
path seamessly and they can be used anywhere later.
The `nm-default.h` header is used widely in the code by many
targets. This header includes different headers and needs different
libraries depending the compilation flags.
A new set of `*nm_default_dep` dependencies have been created to
ease the inclusion of different directorires and libraries.
This allows cleaner build files and avoiding linking unnecessary
libraries so this has been applied allowing the removal of some
dependencies involving the linking of unnecessary libraries.
NM didn't support wpa-none for years because kernel drivers used to be
broken. Note that it wasn't even possible to *add* a connection with
wpa-none because it was rejected in nm_settings_add_connection_dbus().
Given that wpa-none is also deprecated in wpa_supplicant and is
considered insecure, drop altogether any reference to it.
priv->start_buttons and priv->end_buttons are initialized at
construction and never changed and so the checks are not needed.

We no longer add these. If you use Emacs, configure it yourself.
Also, due to our "smart-tab" usage the editor anyway does a subpar
job handling our tabs. However, on the upside every user can choose
whatever tab-width he/she prefers. If "smart-tabs" are used properly
(like we do), every tab-width will work.
No manual changes, just ran commands:
F=($(git grep -l -e '-\*-'))
sed '1 { /\/\* *-\*- *[mM]ode.*\*\/$/d }' -i "${F[@]}"
sed '1,4 { /^\(#\|--\|dnl\) *-\*- [mM]ode/d }' -i "${F[@]}"
Check remaining lines with:
git grep -e '-\*-'
The ultimate purpose of this is to cleanup our files and eventually use
SPDX license identifiers. For that, first get rid of the boilerplate lines.
The library is called "libnm_core". So the dependency should be called
"libnm_core_dep", like in all other cases.
(cherry picked from commit c27ad37c27)
"libnm-core" implements common functionality for "NetworkManager" and
"libnm".
Note that clients like "nmcli" cannot access the internal API provided
by "libnm-core". So, if nmcli wants to do something that is also done by
"libnm-core", , "libnm", or "NetworkManager", the code would have to be
duplicated.
Instead, such code can be in "libnm-libnm-core-{intern|aux}.la".
Note that:
0) "libnm-libnm-core-intern.la" is used by libnm-core itsself.
On the other hand, "libnm-libnm-core-aux.la" is not used by
libnm-core, but provides utilities on top of it.
1) they both extend "libnm-core" with utlities that are not public
API of libnm itself. Maybe part of the code should one day become
public API of libnm. On the other hand, this is code for which
we may not want to commit to a stable interface or which we
don't want to provide as part of the API.
2) "libnm-libnm-core-intern.la" is statically linked by "libnm-core"
and thus directly available to "libnm" and "NetworkManager".
On the other hand, "libnm-libnm-core-aux.la" may be used by "libnm"
and "NetworkManager".
Both libraries may be statically linked by libnm clients (like
nmcli).
3) it must only use glib, libnm-glib-aux.la, and the public API
of libnm-core.
This is important: it must not use "libnm-core/nm-core-internal.h"
nor "libnm-core/nm-utils-private.h" so the static library is usable
by nmcli which couldn't access these.
Note that "shared/nm-meta-setting.c" is an entirely different case,
because it behaves differently depending on whether linking against
"libnm-core" or the client programs. As such, this file must be compiled
twice.
(cherry picked from commit af07ed01c0)
When nmcli needs secrets for a connection it asks them for every known
setting. nmtui is a bit smarter and asks them only for settings that
actually exist in the connection. Make a step further and let clients
ask secrets only for setting that exist *and* have any secret
property. This decreases the number of D-Bus calls when editing or
showing a connection with secrets.

Using strtol() correctly proves to be hard.
Usually, we want to also check that the end pointer is points to the end
of the string. Othewise, we silently accept trailing garbage.
Most of the times we actually need a NMSecretAgentSimple typed pointer.
This way, need need to cast less.
But even if we would need to cast more, it's better to have pointers
point to the actual type, not merely to avoid shortcomings of C.
1) the command line gets shorter. I frequently run `make V=1` to see
the command line arguments for the compiler, and there is a lot
of noise.
2) define each of these variables at one place. This makes it easy
to verify that for all compilation units, a particular
define has the same value. Previously that was not obvious or
even not the case (see commit e5d1a71396
and commit d63cf1ef2f).
The point is to avoid redundancy.
3) not all compilation units need all defines. In fact, most modules
would only need a few of these defines. We aimed to pass the necessary
minium of defines to each compilation unit, but that was non-obvious
to get right and often we set a define that wasn't used. See for example
"src_settings_plugins_ibft_cppflags" which needlessly had "-DSYSCONFDIR".
This question is now entirely avoided by just defining all variables in
a header. We don't care to find the minimum, because every component
gets anyway all defines from the header.
4) this also avoids the situation, where a module that previously did
not use a particular define gets modified to require it. Previously,
that would have required to identify the missing define, and add
it to the CFLAGS of the complation unit. Since every compilation
now includes "config-extra.h", all defines are available everywhere.
5) the fact that each define is now available in all compilation units
could be perceived as a downside. But it isn't, because these defines
should have a unique name and one specific value. Defining the same
name with different values, or refer to the same value by different
names is a bug, not a desirable feature. Since these defines should
be unique accross the entire tree, there is no problem in providing
them to every compilation unit.
6) the reason why we generate "config-extra.h" this way, instead of using
AC_DEFINE() in configure.ac, is due to the particular handling of
autoconf for directory variables. See [1].
With meson, it would be trivial to put them into "config.h.meson".
While that is not easy with autoconf, the "config-extra.h" workaround
seems still preferable to me.

We commonly don't use the glib typedefs for char/short/int/long,
but their C types directly.
$ git grep '\<g\(char\|short\|int\|long\|float\|double\)\>' | wc -l
587
$ git grep '\<\(char\|short\|int\|long\|float\|double\)\>' | wc -l
21114
One could argue that using the glib typedefs is preferable in
public API (of our glib based libnm library) or where it clearly
is related to glib, like during
g_object_set (obj, PROPERTY, (gint) value, NULL);
However, that argument does not seem strong, because in practice we don't
follow that argument today, and seldomly use the glib typedefs.
Also, the style guide for this would be hard to formalize, because
"using them where clearly related to a glib" is a very loose suggestion.
Also note that glib typedefs will always just be typedefs of the
underlying C types. There is no danger of glib changing the meaning
of these typedefs (because that would be a major API break of glib).
A simple style guide is instead: don't use these typedefs.
No manual actions, I only ran the bash script:
