As outlined in commit 36b8dcbe07, we can end up with wrong icons
if the icon theme changes right after a GTK theme change to/from
HighContrast triggered a theme reload.
That's because when we reload icons for the new icon theme, there
are already pending requests due to the icon-style change; those
requests are simply re-used for the new icons, with the existing
icon infos from the old theme.
The above commit applied a simple work-around by changing the
icon theme before the GTK theme, but that only works for the
HighContrast switch in our own UI.
It turns out that Settings also uses the "wrong" order, so the
issue still reproduces with the Universal Access panel.
So instead of relying on everything changing the settings in the
order we expect, cancel all ongoing requests on icon-theme changes.

Since the `MetaSelection` of the global `StClipboard` is private (and
should be), there is no reasonable way for extensions or external code
to query the supported mime-types.
Add `st_clipboard_get_mimetypes()` so this can be queried without

Since e06109c23c we keep old theme nodes
valid during the emission of the "custom-stylesheets-changed" signal.
It turns out that we might still look up the file of a stylesheet using
the files_by_stylesheet hashtable during the emission of that signal,
causing a crash because the assertion in _st_theme_resolve_url() fails.
So fix that and remove the stylesheet entry from the files_by_stylesheet
hashtable after emitting the "custom-stylesheets-changed" signal. And to
be consistent, also remove the entry from the stylesheets_by_file
hashtable after emitting the signal.
Fixes: https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/2757
`StBoxLayout` has a couple properties (`vertical` and `pack-start`)
improperly referenced as signals, and is somewhat unclear these
properties are wrappers around the underlying `ClutterBoxLayout`
properties.
Fix these up and add references to the underlying properties, rather
than redescribing them.
https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/2816
Since we now remove all theme nodes on a stylesheet change (ie.
StTheme's "custom-stylesheets-changed" signal) instead of only
invalidating them, those nodes may not be accessed anymore as soon as
"custom-stylesheets-changed" is emitted.
It turned out though that when comparing them to the newly generated
nodes in `st_widget_recompute_style()` using the
`st_theme_node_paint/geometry_equal()` functions, the properties of the
old nodes will still be accessed, causing a crash since the
CRDeclarations are already freed.
To fix that, keep the reference to the CRStylesheet, which owns the
CRDeclarations used by the theme nodes, around a bit longer, so it's
still possible to access the CRDeclarations inside the
"custom-stylesheets-changed" signal handler. This allows us to compare
the old theme nodes to the new ones since the CSS properties of both are
still valid.
Fixes https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/2709
StThemeNodes are built around the assumption that they're "immutable",
that means they are created once with certain parameters (that resolve
to certain css properties) and then replaced with new ones in case those
parameters changed.
Changes to the internal information stored by theme nodes (i.e. the css
properties, font names or the cached scale-factor) are not all handled
the same though: For changes to the font or the scale-factor we remove
all theme nodes from the cache and let the widgets which are on stage
generate new theme nodes. For changes to the css properties/the
stylesheet, we invalidate the properties of all theme nodes but keep
them in the cache using `_st_theme_node_reset_for_stylesheet_change()`.
So be a bit more consistent and handle changes to the css-properties/the
stylesheet stored by StThemeNodes the same way as changes to the font or
scale-factor.

Theme node invalidation stops at unmapped widgets, and widgets
that forget to chain up to the default ::style-changed implementation.
This may leave stale nodes that were invalidated on
StThemeContext::changed, but are still set on widgets, and maybe
used for CSS property lookups.
Make sure that theme node invalidation happens always by moving
propagation outside the vfunc, and ensure the theme nodes are reset
across the full actor tree. Emission of ::style-changed, and obtaining
a new theme node may be delayed till when the actor is mapped.
The theme node is also cleared after unparenting an actor to avoid
stale references.
This ensures that all widgets get their theme node cleared after
stylesheet changes, instead of maybe being left with a theme node
that's been cleared of all its properties.

Since commit 6a42d77261 we invalidate the
cached properties for each theme node on stylesheet changes by iterating
over the hashtable of the theme context instead of listening to the
signal in each individual theme node.
That commit forgot one particular node though that's not stored in the
hashtable, but using the `priv->root_node` property instead: The theme
node that belongs to the stage.
So make sure we also invalidate the cached properties of the stage theme
node on stylesheet changes. This fixes various crashes that happened
with extensions providing custom stylesheets (emitting the
"custom-stylesheets-changed" signal on every extension enable/disable),
trying to access an already freed CSS property of the stage.

Commit c89d6a633 introduced a default fallback icon that would be displayed in
case the main gicon or the fallback gicon wasn't set or failed to load.
This broke the use case where a StIcon is created but no main icon or
fallback icon are set on purpose, for example the appindicator extension
which always creates a StIcon to represent icons in menu items but the
actual icons are only set if the application provides one, leaving the
menu showing the default fallback ("image-missing") icon for all menu
entries that don't actually have an icon provided by the application.
Fix that by only using the default fallback icon if the provided one
failed to load.

It seems reasonable that an entry shouldn't allow entering text when not
reactive. The same could be achieved by changing the text's :editable

which may result in an unwanted size change.

The text is part of the entry, so it is surprising that it can

(yes, again).
The idea behind commit 3dd8ffc2bb to try harder to avoid empty
icon actors because of missing icons was sound, so implement that
behavior in StIcon itself:
If the main gicon was not found, and the fallback gicon isn't set or
wasn't found either, fall back to the standard 'missing-image' icon.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1127
The commit broke StIcon's :fallback-gicon property, as it relies on failure to load
an icon to determine that the fallback should be shown.
Luckily StIcon is the only user of st_texture_cache_load_gicon() (at least in
regular shell code), so we'll be able to implement the 'image-missing' fallback
there.
This reverts commit 3dd8ffc2bb.

Rely on the Pango renderer handling this properly, instead of tinting

If a given icon is not available for neither the current theme nor any
of the fallback options (default theme -"Adwaita", "gnome"...), the
call to gtk_icon_theme_lookup_by_gicon() will return a NULL value, which
returned by the Shell Toolkit as is, causing trouble in the Shell's JS
code when calling shell_app_create_icon_texture() to create an icon.
To at least mitigate the chances of this having this issue happening, we
should at least try to load the standad 'image-missing' icon from the
Icon Naming Specification spec when we receive a NULL here, so that
at least we try to show something to the user, even if it's ugly.

Commit 88ac339774 changed StEntry behavior so the text hint would
stay visible while focused, as long as the text buffer is empty.
However, IMs that use preedit still should count as "started typing",
while the text buffer is still officially empty.
To fix this, check on st_entry_update_hint_visibility() that there's
indeed no preedit buffer before showing the hint. We can't directly
listen to internal preedit buffer changes in ClutterText, so handle
preedit buffer updates through the ::cursor-changed signal that will
be indirectly emitted.

st_texture_cache_bind_weak_notify calls g_clear_signal_handler which

St has the regular abstractions to handle actors that are bigger

We're storing in the texture cache images and scaled images appending
the scaling factor to the key. When a file changes the cache key
corresponding to that file is removed, but not the keys for the scaled
ones so that images in the cache are never reloaded.
This patch removes all keys from the cache related to the file that
changes, including those with the scaling factor.
A new set (hash table) was added to keep track of scale used to be able
to remove all possible images in the cache.
When the KEY is removed from the cache, we can look now in the scale set
for and each scale we also remove the key "KEY1.000000", "KEY2.000000",
etc.
Assuming that the number of used scales is small (I would typically
expect one or two), the overhead should be negligible.

Instead of every individual StThemeNode. There are essentially two kinds
of theme nodes: Those we create for lookups, and those interned by the
theme context and used by StWidgets. Listening to the signal on the former
is pointless as they are short lived and not meant to be really used for
drawing. So it is only essential to track stylesheet changes in those we
intern for later use.
This change does precisely that, it lets the StThemeContext track the
stylesheet changes and let all known theme nodes reset their state for
it.
The internal array holding all connected handlers for this signal in glib
was about the biggest single allocation made in gnome-shell, as interned
theme nodes nodes are around the 4 to 5 digit numbers. This essentially
makes it disappear.
This however means that widgets that are explicitly set a theme through
st_widget_set_theme() don't get their theme node implicitly updated.
There's little reasons to use that API, so perhaps this is an acceptable
tradeoff.

A StWidget could get its style from a) a theme set in the StThemeContext,
and b) directly through it's ::theme property. Generally, overriding CSS
through the latter cannot be recommended as it loses any connection with
the global theme (eg. the ones you get through selector specificity).
It sounds a bit too powerful and pervasive, there's no use for it in
gnome-shell and doesn't look like something that could be recommended on
extensions. So, just drop this piece of API.

By now, all containers and layout managers except StBin (and its
subclasses) use the generic ClutterActor expand/align properties
to control how their children are laid out.
This is particularly confusing as two or the properties StBin uses
for layout - x-align and y-align - shadow the generic ClutterActor
ones, but work very differently: They use a different enum and
determine how the bin lays out its child, instead of how the bin
is laid out by its parent.
Address this by deprecating the StBin properties and using the same
generic ClutterActor properties as everyone else.

Whenever an app is installed, the usual routine is
to run 'gtk-update-icon-cache' after installing all
of the app's files.
The side effect of that is that the .desktop file of
the application is installed before the icon theme
is updated. By the time GAppInfoMonitor emits the
'changed' signal, the icon theme is not yet updated,
leading to StIcon use the fallback icon.
Under some circumstances (e.g. on very slow spinning
disks) the app icon is never actually loaded, and we
see the fallback icon forever.
Monitor the icon theme for changes when an app is
installed. Try as many as 6 times before giving up
on detecting an icon theme update.

The texture cache, right now, only monitors for
complete theme changes. If the contents of the

StAdjustment implements the ClutterAnimatable interface, so we can

But as it is currently not possible to associate a transition with

st_theme_node_paint_equal() was originally added to preserve paint state

Images are loaded either with a supplied fixed size, or using the "native"
dimensions of the file. When creating a content image from the loaded data,
we currently simply apply this directly to the preferred size.
This works usually fine: GdkPixbuf will always keep the aspect ratio, so
if only one dimension is provided, the other will be adjusted accordingly:
Loading a 200x200 image with a requested size of (100, -1) will result in
a 100x100 content image.
There is a catch though: GdkPixbuf will only scale *down* to the requested
size, no up. That is, loading a 100x100 image with a requested size of
(200, -1) will result in a 100x100 pixbuf. But as we assume that the pixbuf
size matches the requested size, the image content ends up with 200x100.
Fix this by explicitly handling the case where only one size was supplied,
and make the other dimension take the aspect ratio into account

Actors themed through CSS should ideally get sizes and positions that
conform to the "pixel grid". A notorious example is the panel that has a

If the requested height is a multiple of the scale factor, the workarea

error while loading shared libraries: libmutter-cogl-4.so.0: cannot
open shared object file: No such file or directory

The executable is assumed to be run from $top_srcdir/src, which is
essentially an autotools left-over (it's where the program ended
up with srcdir == builddir).
Now with meson, its actual srcdir makes more senses.

Clutter no longer hard-codes a resolution of 96 DPI (although that's
still the default), so any assertions of sizes for physical units
may be off.
Fix this by setting up the test environment according to the
assumptions.

While mapping the :first/:last-child pseudo classes directly to the
ClutterActor:first-child/:last-child properties allows for an easy
implementation, it is unexpected that rules can appear to not have
an effect because the selected child is hidden. GTK's behavior of
applying the classes to visible children makes much more sense, so
change our implementation to do the same.

It might happen that the target clutter actor that we return on call
of st_texture_cache_load_sliced_image might be destroyed while the
loading task is still running. To protect from this, let's connect
to "destroy" signal and when this happens we use a cancellable to
stop the task.
This allows to safely reuse the return value of this function to
cancel the execution and avoiding that load_callback is called
even for a request that is not anymore under our control.

When loading an actor for a sliced image actor, we can now use the
REQUEST_CONTENT_SIZE request-mode for the actor since we the content image
has now a predictable size and thus we can be sure that the size will be applied
taking care of the resource scale.

Create StImageContent as a simple ClutterImage with preferred width/height
properties in order to be able to use explicit sizing when creating clutter
contents that will be applied to actors whose size depends on the content itself.

Instead of just passing a scale when getting a cached icon, pass both a
'paint_scale', the scale of which the icon will be painted on the
stage, and a 'resource_scale', the scale of the resource used for
painting.
In effect, the texture size will use the scale 'paint_scale * resource_scale'
in a ceiled value while the size of the actor will use 'paint_scale' when
determining the size.
this would load a bigger texture, but the downscaling would keep the visual
quality.
