To ensure that the watch is properly re-set every time, call
watch_keys() from the watch callback. Previously the watch was only
renewed after a data update was done in a worker thread, which made
no sense, since the update function was implemented in such a way
that it can (and should) be re-triggered on each key change, until
the changes stop coming, and that can only happen if we renew
the registry watcher right away.
If a key watch is renewed from the key watch callback, it results
in the callback being NULL, since we clear it after we call it.
Rearrange the function to make sure that the changes done by the
callback function are preserved properly.
This function can, in fact, return STATUS_SUCCESS. We shouldn't
assert that it doesn't.
For now interpret it just like STATUS_PENDING (i.e. APC will be called),
see how it goes (it isn't documented how the function behaves in this
case, we have to play it by ear).
Note that while we *can* use a better-documented RegNotifyChangeKeyValue() here,
it communicates back to us via event objects, which means that the registry
watcher would have to interact with the main loop directly and insert its
events (plural; one event per key) there. That would make the API more complicated.
Whereas the internal NT function communicates by calling an APC - we're good
as long as something somewhere puts the thread in alertable state.
We want to have the ability to mark types that should not be derivable
even if they are in a deeply derivable type hierarchy; in other words,
leaf nodes in the types tree.
When attempting to test Windows support for building libadwaita, since we are
using multiple GResource files, one would hit linker errors where multiple
definitions of the following symbols have been defined, when
glib-compile-resources was invoked without manual register:
resource_constructor_wrapper
resource_destructor_constructor
_arrayresource_constructor
_arrayresource_destructor
In order to avoid that, just prefix the definitions of resource_constructor
and resource_destructor, like what we do when --manual-register is used, with
what we pass in with --c-name so that we ensure that we do not end up in such
name collisions.
g_source_set_name duplicates the string, and this is
showing up as one of the more prominent sources of strdups
in GTK profiles, despite all the names we use being literals.
Add a variant that avoids the overhead.
