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.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/779
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.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/779
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.

The use of box-shadow on a StWidget that has a background-gradient was
not been rendered correctly, the shadow borders was calculated inside
the st_theme_node_prerender_shadow function and in the case that we've a
prerendered_texture the max_borders was not calculated and are 0.
This patch creates a new static function to compute shadow maximum
borders copying the code from st_theme_node_prerender_shadow, and call
this new method in the case that we've a prerendered_texture.

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
icon theme change, however, the texture cache
isn't properly invalidated.
This manifests itself as a randomly reproducible
bug when installing an app; the app icon may be
the fallback forever, or as long as something else
updates the icon theme.
Watch for the GtkIconTheme:changed signal, and
evict the texture cache when the theme changes.

StAdjustment implements the ClutterAnimatable interface, so we can
already animate its properties with ClutterPropertyTransitions.
But as it is currently not possible to associate a transition with
an adjustment, it must be owned (and kept alive in case of GC) by
the calling code.
Change that by implementing the same (add|remove|get)_transition() API
as ClutterActor, so we can use a familiar API and even duck typing in
case of javascript.

`g_object_notify()` actually takes a global lock to look up the property

st_theme_node_paint_equal() was originally added to preserve paint state
when a style change didn't affect any of StWidget's cached background
resources.
That's why using it for filtering out unneeded style changes as in commit
f662864a misses any non-background related properties that are relevant
for subclasses. Add additional tests to make sure we keep emitting the
signal in those cases.

Util.ensureActorVisibleInScrollView takes care of the potential scroll view fade
effect in order to compute the scroll offset, reading the ScrollViewFade's
`vfade-offset` property. This was correctly working until gnome 3.30 cycle.
However such property isn't defined now because since gjs 1.54, it can only
fetch introspected properties and St.ScrollViewFade was considered a private API
not exposed by gir.
Fix this by also introspecting st-scroll-view-fade sources.
Not being considered private anymore, install the header.

Updating the :first/:last-child pseudo classes can result in a lot

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

The parameters that may affect the icon on ::style-changed are more size

With a high enough amount of actors, there may be enough theme nodes and

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
height of 1.86em. On unchanged font settings and hidpi that translates to
55px, which leaves the workarea with "half pixels" that hidpi wayland
applications don't know how to fully cover.
If the requested height is a multiple of the scale factor, the workarea
and maximized applications can then work on full pixels.

With StImageContent, the meaning of passing -1 as size parameter changed
from "load the image at its preferred size" to "abort the session". It
is therefore no longer possible to just load the image and then have it
scaled by applying a CSS size to the texture's parent.
Setting the size from CSS is useful though, so to still allow that, fall
back to the actor's size (which can be determined by the style).

While mapping the :first/:last-child pseudo classes directly to the

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

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.

Create the surfaces for background shadows at scaled sizes and then draw on them
using logical coordinates, by setting the surface device scale accordingly.
Use the said surface scale when generating the actual shadow cairo pattern
but in such case, to reduce the number of code changes, is better to work in
absolute coordinates, and to do so:
1) Create a temporary shadow-spec copy with scaled values to absolute sizes
2) Invert the scaling on the shadow matrix
3) Do the actual painting in absolute coordinates
4) Set the shadow matrix scaling back to the logical coordinates.
Finally scale down the created shadow pattern surface size when painting it,
applying again a reverse scale to the matrix.

A fractional resource scale would mean we never use the fast path for
creating the shadow, because we'd cast the int to a float before

actually potentially trigger the fast path.

The fade shader will draw the fade effect up until the border pixel. If

consists of more than one physical pixel.

This commit makes StWidget manage the scale of which its associated
resources should be multiplied with. The resource scale is calculated
by clutter, and is retrieved by clutter_actor_get_resource_scale(). Due
to the resource scale not always being available, the getter may fail,
and the actual widget that draws the content will have to deal with
this situation.
As the resource scale depends on where on the stage the widget is drawn,
the resource scale will in general be available once the widget is
mapped.

Since commit deec0bf255, the texture cache is based on ClutterImage
rather than ClutterTexture. As ClutterImage (like all ClutterContent)
is only concerned with painting, it doesn't influence the size of the
actor it is added to at all, and the returned actor will now stay at
size 0x0 after the image has been loaded.
Set up the actor to follow the content's size instead, to get closer
to the previous behavior.

_st_create_shadow_pipeline_from_actor creates shadow pipelines
from actors. This function special-cases ClutterTexture as a
small performance improvement, since we can have access to the
CoglTexture easily with it. However, recent commits removed all
usage of ClutterTexture from GNOME Shell, rendering this optimization
useless. Instead, actors now may have a ClutterImage set as
their content, that can be used instead.
Replace the check for ClutterTexture with a check for ClutterImage,

This drops usage of Gtk/X11, replacing it with code that is dependent

The last patch in the series, this one adapts StShadowHelper
to received a CoglFramebuffer. This is where we first touch
JavaScript with Cogl types, and as such, it depends on the
latest Mutter. Earlier versions of Mutter didn't have its
Mutter-Clutter GIR to generate types for various Cogl types.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/283
Same case of the previous patch; _st_paint_shadow_with_opacity()
uses cogl_get_draw_framebuffer(), and this patch makes it receive
a CoglFramebuffer as a parameter instead.
The cautious reader might notice that this commit apparently goes
against the long-term goal, for it introduces more instances of
cogl_get_draw_framebuffer(). This is not wrong, but these introduced
ones will be removed later on, when ClutterActor.paint() receives
a CoglFramebuffer as a parameter instead.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/283
This is in preparation for a future where only explicit frambuffer
APIs are available, i.e., cogl_get_draw_framebuffer() does not
exist.
There is absolutely no functional changes in this patch (nor the
following ones in this series), only rearrangements so that various
functions receive a CoglFramebuffer instead of using the draw
framebuffer.

Handling those events is neccessary if a touch event that pressed down a
button turns out to be a gesture. In this case the button should be
released without emitting the clicked signal.
After loading the GdkPixbuf, StTextureCache unconditionally
creates a ClutterImage and, if it's not in the cache, add
it to the cache. That's a waste of resources when the image
is already committed to the texture cache.
Fix that by reusing the ClutterImage of the cache if it is
already there; otherwise, create a new ClutterImage as we
were previously doing.
ClutterTexture is a deprecated class that is simultaneously
an actor, and the content of the actor. Clutter's new model
is to separate painting (via ClutterContent) from actors.
Currently, StTextureCache relies on ClutterTexture to store
the loaded textures. This not only does not match the latest
practices of Clutter, but also generates various compile-time
warnings.
Port StTextureCache to store ClutterImages instead of storing
ClutterTextures. ClutterImage exposes the internal CoglTexture,
so no helpers are needed to match the current StTextureCache
API. Aspect ratio was dropped, but from my testing, it doesn't
change anything.
When computing the effective border color, we operate on colors with
premultiplied alpha to simplify the calculations, then unpremultiply
the result. However we miss a bounds check in the last check, so any
color component can overflow the allowed maximum of 0xff and shift the
result in unexpected ways.

If the actor is not on the stage yet (i.e. does not have a theme
node), but has a paint state cached, we currently fail to invalidate
it, which will lead to the actor painting with old contents once it
gets onto the stage.
This commit fixes the issue by changing our invalidation strategy;
previously we were looking at the widget's own theme node to determine
if it should be invalidated or not.
Now we look at the theme nodes of our cached paint states. When the
widget is mapped on stage, those are the same as the widget's own
theme node, but when the widget is not on the stage, we'll still be
able to invalidate them.
As part of this, we move the invalidation API to StThemeNodePaintState,
which is a more natural place for our use case.

In X11, pointer emulated touch events are replicated with normal PRESS, RELEASE
pair events which are generated by the server. Thus for a single tap we get:
- TOUCH_BEGIN -> TOUCH_END, PRESS -> RELEASE
This will cause st-button to send two "clicked" signals, instead of just one,
breaking extensions (like dash-to-dock) that show buttons in the main stage
which will be checked two times or that will receive the same signal two times.
cogl_texture_new() is used in a few places in GNOME Shell, but
it's a deprecated Cogl function. The replacement is the less
verbose cogl_texture_2d_new_with_size(), that is very much a
straightforward replacement.
Remove the few places where this function is used, replacing
it by the CoglTexture2d counterpart.

StTextureCache installs file monitors that invalidate caches when
contents of the underlying file change.
At the moment, the cache uses the Gio.FileMonitorEvent.CHANGED event
type to make that determination.
However, that is suboptimal for at least two reasons:
- while a file is being written to disk, many CHANGED events will be
emitted in sequence. That will cause needless cache invalidations,
and we will risk loading the file before it's fully loaded.
- if an existing file is replaced, e.g. with g_file_replace(), we may
not get a CHANGED event but a CREATED one instead, so the cache ends
up never getting invalidated.
The good news is that in both of those cases GFileMonitor will send a
CHANGES_DONE_HINT event after changes have settled, or after the file
is replaced.
This commit fixes both cases by switching from the CHANGED event to
CHANGES_DONE_HINT to determine that a file has in fact changed.

According to Clutter documentation, "[…] actors implementing the
ClutterContainer interface should override the default implementation
of the class handler of this signal and call clutter_actor_destroy()
on their children."
StBin was doing that in GObject:dispose() instead. Move the child
destruction to a new ClutterActor:destroy() vfunc override.
StBoxLayout implements StScrollable, which, semantically, means that
the StBoxLayout size may not match the minimum size reported by the
layout manager. In this specific case, the layout manager by is a
ClutterBoxLayout by default. For example:
+--------------+
| Viewport |
+------+--------------+-----------------+
| | | |
| | | Content |
| | | |
+------+--------------+-----------------+
| |
+--------------+
So, assuming that:
- ContentSize = the minimum size of the content;
- ViewportSize = the allocated size of the viewport;
When allocating StBoxLayout, it must assume ViewportSize, but must
pass ContentSize to the layout manager. That way, the children of
StBoxLayout are correctly placed within it, even if it's bigger than
ViewportSize.
And here's the problem: right now, StBoxLayout assumes ViewportSize
AND also passes it to layout manager. Commit 77c4c6b6d specifically
exposed this bug by relying entirely on StBoxLayout to arrange the
app and window icons.
Fix that by using ViewportSize to allocate StBoxLayout itself, but
passing ContentSize to the layout manager.

All adjustment setter functions take good care of avoiding emission of
notify:: when it's not needed. The set_property() implementation already
calls into the setter functions, so mark the properties as EXPLICITY_NOTIFY
in order to optimize notify:: emission away through g_object_set (rather
common from JS code).
The actor allocation doesn't change per-se, but apply_transform()
will practically transform it. In order to have the paint volume
update accordingly, queue a relayout.
The default get_paint_volume() implementation will do the union
of children, and the child ClutterText paint volume may expand
beyond StEntry size when text overflows.
We actually want all content to be clipped to the StEntry, so
implement get_paint_volume() and tell it so.
And constrain it in StScrollView instead (instead of falling back to an
infinite paint volume, as the actor as paint/pick impls, but no
corresponding get_paint_volume one).
Fixes artifacts with the AppView (and possibly other places) when paint
volumes are aggressively cached.
The default keyed_surface is meant to handle CoglTextures thus we can't
add cairo surfaces to it, as the DestroyNotify function won't handle them.
Then the quicker way is to just add another Hash table for handling
such types of textures, with proper destroy function.
This might cause a crash when cleaning up the cache as the hash table has
cogl_object_unref as DestroyNotify function but that assumes that
the passed object is a valid CoglObject.
Fixes: #210
The instance is owned by the actor (being its child), and thus when the
disposal happens for the parent the text is disposed too, thus it's just
safer to nullify its reference so that we won't try to access to invalid
objects later, and this might be the case since the JS objects could be kept
around until they aren't finalized.

Call _st_set_text_from_style() when updating the entry's style, so
that CSS style properties such as text-decoration or letter-spacing
are applied over the internal ClutterText instance.
If an actor is pending a relayout when get_allocation_box() is called,
the method forces an allocation update. In case of StWidget, this might
then result in a style update and a consecutive invalidation of the
shadow spec.
A helper method that invalidates one of its parameters as a side effect
(and by extension its return value as well) is most unexpected, so cur-
rently _st_create_shadow_pipeline_from_actor() poses an easy trap to
callers to run into.
Remove that trap by calling get_size()/get_position() instead, which
don't have the unintended side effect - it is still a good idea to fix
callers who were running into this to not waste resources on creating
shadows that are invalidated before the next paint, but throwing un-
defined behavior at them is harsh ...
https://bugzilla.gnome.org/show_bug.cgi?id=788908
The st_button_release() call wouldn't happen because StButton does not
set priv->button_mask on touch events. And if we make it called, we can't
try to unset the device grab at the end of the function, as device/sequence
are unset earlier on.
When creating a shadow for a ClutterTexture, we currently use the
underlying CoglTexture directly instead of rendering the actor to
an offscreen buffer. This assumes that the CoglTexture is directly
suitable as shadow source, which isn't necessarily the case - it
may have a very different size than what is shown and scaled up or
down by the hardware. In that case we end up with a scaled shadow
texture as well, which messes up the desired blur effect - the
result will be too light when scaling up, or too sharp when scaling
down. To fix this, only take the shortcut when a ClutterTexture's
underlying texture has the correct size and fall back to offscreen
rendering otherwise.

Unlike pango_font_description_from_string(),
pango_font_description_set_family() requires a already properly
formatted font family string. The proper format is a comma seperated
list of font families, but we generated a "comma space" separated list.
Passing a incorrectly formatted font family string to pango seems to
cause wierd issues, where the wrong font is sometimes selected.
For example, this fixes a font selection issue on zh_TW.UTF-8 locale for
chinese characters, where previously the "Droid Sans" font was selected
instead of "Source Han Sans TW" even though fontconfig had placed
"Source Han Sans TW" before "Droid Sans".

Compiling the generated source for each consumer of the dependency
means we end up trying to register the enum types multiple times,
resulting in a fatal failure on startup. Luckily code outside libst
itself only depends on the header, which doesn't cause those issues.
st_built_sources contains the source and header generated by mkenums,
not any other generated sources. Clarify that in the name, as we are
about to use source and header separately.
We cannot rely on any build order, except the one we specify ourselves.
St depends on various generated files; other targets depend on those
files existing, so they can be included. There is no direct relationship
between targets and files, unless we declare a dependency, using the
Meson declare_dependency() constructor — which allows us to replace the
various `link_with` directives with the more appropriate `dependencies`
one, and also allows us to specify sources that must exist by the time
we build those targets.
In parallel builds we may end up with st-enum-types.c being built inside
separate targets outside of src/st which may not have the ST_COMPILATION
pre-processor symbol defined. For this reason, we need to define it
ourselves in the source file, before including other headers, to avoid
the single-include guard.
Meson is on track to replace autotools as the build system of choice,
so support it in addition to autotools. If all goes well, we'll
eventually be able to drop the latter ...

Even though the API documentation doesn't say so, the underlying
Cogl texture of a ClutterTexture may be unset, so check for that
case to avoid a runtime warning.
https://bugzilla.gnome.org/show_bug.cgi?id=784353
This allows a full ClutterActor to be used as hint in the entry, instead
of a simple string.
The string case has been now re-implemented on top of the hint actor.
https://bugzilla.gnome.org/show_bug.cgi?id=783484
This is the same as the previous commit, but for StEntry.
We don't have any need to explicitly destroy this actor in our dispose
implementation, and doing so breaks the assumption that we can access
the clutter_text from within destroy.
https://bugzilla.gnome.org/show_bug.cgi?id=783483
There's no need to explicitly destroy the ClutterText actor inside the
label; doing so is actually harmful, as it will break the normal
reference cycle between container and children.
As StLabel doesn't hold any extra reference to the ClutterText actor and
just uses clutter_actor_add_actor() to add it to itself, let the normal
container dispose cycle run to dispose of the reference.

Commit ffe4eaf00d broke the handler by fetching the instance private
from the wrong actor - as we don't use the ::primary-icon-clicked signal,
and the ::secondary-icon-clicked signal still works by accident, nobody
noticed until now ...

When extracting the sliced image, the GTask grants data ownership on
g_task_propagate_*, so the pixbuf list must be properly freed. On async
load, we just left a dangling reference when returning on the async
task.

st_theme_node_get_border_image() may return %NULL, leading to a
segfault in st_border_image_get_file() when glib is compiled with
G_DISABLE_CHECKS.

It isn't useful to move the keyboard focus to a hidden actor, so
only include visible actors in the focus chain - this is in fact
the documented behavior of st_widget_get_focus_chain(), so having
the default implementation return all children has always been
unexpected.
https://bugzilla.gnome.org/show_bug.cgi?id=778158
Sliced images are loaded into a group actor with one child actor
per slice. In case loading the image fails, we currently quietly
return the empty group actor, which makes diagnosing problems
unnecessarily hard - just be a bit more verbose on failure.

Other windows like the mutter Xwayland selection bridges might deal with
the clipboard, which would result in events visible on st-clipboard event
filters.
In order to avoid unintended results, ignore events that are not meant for
the clipboard window.

We're using an unitialized box resulting in an undefined shadow box
size.
_st_paint_shadow_with_opacity() already computes the shadow's bounding
box from the source actor's box so we just need to pass that along.

on_custom_stylesheet_changed() would set properties_computed to FALSE
without freeing the old properties, then the properties pointer would
be overwritten in ensure_properties().

Checking offscreen for COGL_INVALID_HANDLE is not sufficient,
as cogl_offscreen_new_with_texture doesn't initialize framebuffer
objects but lets Cogl solve this the lazy way.
cogl_offscreen_new_with_texture will never return COGL_INVALID_HANDLE
anyways.

For shortcuts that involve a letter (like <ctrl>c), we currently only
accept the lower-case variant. This makes shortcuts awkward to use when
caps-lock is active, and is inconsistent with GTK+, so accept upper-case
variants as well.

While CoglError is a define to GError, it doesn't follow the convention
of ignoring errors when NULL is passed, but rather treats the error as
fatal :-(
That's clearly unwanted for a compositor, so make sure to always pass
an error parameter where a runtime error is possible

If cogl_framebuffer_allocate fails in _st_create_shadow_pipeline_from_actor, the
CoglOffscreen* that was allocated earlier in the function is leaked.

This never worked since the code landed but apparently no-one noticed
until now.
The intent here is to return the accessible's default role if none has
been explicitly set on the StWidget instance.
https://bugzilla.gnome.org/show_bug.cgi?id=760945
Commit ffe4eaf00d changed this code to
call st_widget_get_accessible_role() instead of using the value
directly which would be an infinite recursion if that function didn't
have a bug. As it is, this just resulted in
CRITICAL **: atk_object_get_role: assertion 'ATK_IS_OBJECT
(accessible)' failed

Since commit 48a54e8ac4, paint() has an explicit framebuffer parameter,
however a couple of submethods are still using the draw framebuffer,
which breaks when rendering to an offscreen buffer.
If we are trying to render a shadow at a size that is very large in one
direction, but small in the other direction (so that we don't 9-slice
the texture), then allocating the backing texture for the offscreen
buffer may fail due to texture-size limits. Don't crash in that case.

There are quite a few crashes in retrace.fedoraproject.org that are a result of
of cairo_pattern_get_surface() failing, then a subsequent call to
cairo_image_surface_get_width() crashing because no surface was returned to the
out parameter. Knowing what causes these is hard - my best guess is widgets getting
allocated at ridiculous sizes - but avoiding the crash makes sense in any case.

Cut down on boilerplate by using the (no longer that) new helper
macros. We don't care about breaking ABI in private libraries, so
use G_DECLARE_FINAL_TYPE even where the class struct used to be
exposed in the header, except for types we inherit from ourselves
(obviously) or where the class exposes any vfuncs (where changes
could affect inheritance in extensions).
They are unused, as we don't use them ourselves and the class is not
exposed to introspection. Drop them to allow defining the type as final
in an upcoming commit.
