The name prefix "nmtst_*" is reserved for test helpers and stub
function. Such functions should not be in the actual build artifacts,
like the NetworkManager binary.
Instead, nmtst_connection_assert_unchanging() is not a test helper. It
is a assertion function that is only enabled with NM_MORE_ASSERTS
builds. That's different.
Rename.
In other words,
$ nm src/core/NetworkManager src/libnm-client-impl/.libs/libnm.so | grep nmtst
should give no results.
NMConnection is a glib interface, implemented only by NMSimpleConnection
and NMRemoteConnection.
Inside the daemon, every NMConnection instance is always a NMSimpleConnection.
Using glib interfaces has an overhead, for example NM_IS_CONNECTION() needs
to search the implemented types for the pointer. And NM_CONNECTION_GET_PRIVATE()
is implemented by attaching user data to the GObject instance. Both have measurable
overhead.
Special case them for NMSimpleConnection.
This optimizes primarily the call to nm_connection_get_setting_connection(),
which easily gets called millions of times. This is easily measurable.
"libnm-core/" is rather complicated. It provides a static library that
is linked into libnm.so and NetworkManager. It also contains public
headers (like "nm-setting.h") which are part of public libnm API.
Then we have helper libraries ("libnm-core/nm-libnm-core-*/") which
only rely on public API of libnm-core, but are themself static
libraries that can be used by anybody who uses libnm-core. And
"libnm-core/nm-libnm-core-intern" is used by libnm-core itself.
Move "libnm-core/" to "src/". But also split it in different
directories so that they have a clearer purpose.
The goal is to have a flat directory hierarchy. The "src/libnm-core*/"
directories correspond to the different modules (static libraries and set
of headers that we have). We have different kinds of such modules because
of how we combine various code together. The directory layout now reflects
this.
