We need to match the conditions in g_object_init
for when we already have a freeze. Without that,
we underflow the freeze count and trigger a
warning.
Fixes: #2666
Beef up the singleton testcase to reproduce a
freeze count underflow when setting properties
at construction time, with a custom constructor.

These are deprecated, but it’s easy enough to test them anyway. This
bumps up code coverage a bit and hopefully ensures we don’t accidentally
regress on them in future.

At the moment these tests basically just ensure that the program’s
compiled properly and doesn’t crash on startup. They don’t check
functionality very deeply.
But they’re a start.

This has been documented in `man gobject-query` for a long time, but
seemingly never implemented.

This makes the output a lot nicer to read:
```
│
├void
│
├GInterface
│ │
│ └GTypePlugin
│
├gchar
⋮
```
rather than
```
|
`void
|
`GInterface
|
`GTypePlugin
|
`gchar
⋮
```
It includes a change to correctly use vertical tees at the top level by
correctly setting the sibling node rather than always setting it to
zero.

This doesn’t change the tests’ behaviour, but moves them to a slightly
more logical location.
They are still not installed or run by default.

Helps: #1434
Install the properties with a mixture of
g_object_class_install_properties and
g_object_class_install_properties, and verify
that finding them still works, regardless of
whether we use string literals or not.
When the param specs are provided as an array
with g_object_class_install_properties, keep
a copy of that array around and use it for
looking up properties without the param spec
pool.
Note that this is an opportunistic optimization -
currently, it only works for properties of the
class itself, not for parent classes, and it
only works if the property names are identical
string literals (we're at the mercy of the linker
for that).
If we don't get lucky, we fall back to using
the pspec pool as usual.
This may fix Coverity assuming that pspecs are leaked, which is causing
tens and tens of false positives in the latest Coverity reports for
GLib.
Ensure that the pspecs are sunk (if floating) even if adding them to the
class fails (due to validation failure or an identically named property
already existing).

This reverts commit 0ddea2d8e2.
The commit was based on the misunderstanding that types
declared with G_DECLARE_FINAL_TYPE are actually non-derivable.
But that is only the case for types defined with
G_DEFINE_FINAL_TYPE.
Fixes: #2661
If we have no nontrivial notify vfunc, and no signal
handlers for notify, we don't need to maintain the
notify queue. No need to notify if nobody's listening.
Check whether an object has a nontrivial notify vfunc
and avoid creating and updating the notify queue if
it doesn't. We know that there can be no notify signal
handlers at this point. No need to notify if nobody's
listening.
We currently keep a flag for whether an object has
ever had any signal handlers. But even if it had signal
handlers, it may not have any notify handlers. Keep that
information separately, so we can speed up property setting.
According to the commit that introduced these
calls (4b334ef8f1), we are checking
the refcount here to avoid calling g_object_ref
when the refcount is 0, in the rare case that
notification would be triggered during finalize.
But we are now freezing notifications during
finalize, and after recent changes, we no longer call
g_object_ref for notification while a freeze is
in place.
We only need to take a ref on the object when
we call out to external code (ie around
->dispatch_properties_changed). If we avoid
the signal emission, we can avoid the ref/unref
too. This is not currently happening, but
might in the future.
A small reorg that reduces the code and matches
what we do for object_get_property.
Note that as a consequence of this change, we now
check the deprecated flag on the redirected property,
not on the original when setting properties. This
matches what we were already doing for getting
properties.
The code that emits property deprecation warnings
rarely runs, and doesn't need to be inlined
everywhere. It is enough to inline the check for
the deprecation flag.
It is safe not to copy arguments here,
because we are not emitting any signals
before we are done setting the values
as properties.
This matches what we do for g_object_new now.
We can safely use the values without copying here.
This is safe because we are not emitting any
signals before we are done setting the values
as properties.
None of these messages are particularly helpful, but they increase the
overall test log output size, which has to be stored by the CI for every
test run.
With these messages removed, the size of a full test log is reduced from
6.5MB to 1.8MB for me.
