"Yo, we heard you like traversing NULL-terminated arrays to operate on
them, so we called g_strv_length() as the for condition, so you can
iterate the array while iterating the array."
Instead of making famed rapper and television producer Xzibit proud, we
should avoid calling g_strv_length() on an array while looping on the
array, to avoid quadratic complexity.
We do this in various places that deal with arrays of strings that we
cannot really guess are short enough not to matter — e.g. the list of
CSS selectors in the inspector, or the required authentication
information for printing.
Previously, the unpremultiplied values from the GdkRGBA were taken. Now
we premultiply the color values as specified by the CSS specs.
This is only relevant when transitioning with translucent colors.
An example is the halfway transition between transparent (0, 0, 0, 0)
and white (1, 1, 1, 1). Previously, all 4 values where transitioned
separately and the result was semi-transparent gray (0.5, 0.5, 0.5,
0.5).
By depending on the alpha value, the result is now semi-transparent
white (1, 1, 1, 0.5) which is what one would naively expect.
New reftest: color-transition
On some slower machines (e.g. an ARM OBS builder), this test is failing
with a race condition where we're trying to fetch the style before it's
applied.

gtk-reftest already had an --output=DIR option to tell it where
to save all the resulting images. Now you can combine this with
the --compare-with=DIR option in a second run to make gtk-reftest
compare the .out.png files from the first run with the .out.png
files of the current run, instead of producing .ref.png files.
The intended use for this is to verify that changes do not affect
the generated output.
Sometimes path nodes can survive longer than the style context that
created them. Don't crash in those cases.
Fixes startup of mutter.
Testcase included.

We are testing -gtk-icon-style and assume the theme doesn't touch it.
But HighContrast forces symbolic icons. And that breaks the reference
images.
So explicitly set "requested" for everything.
It seems to be buggy in ways that make the test fail
with a critical when the test bus is brought down.
At the same time, drop manual settings of environment
variables that we can set globally.
gtk_tree_selection_real_modify_range() has a g_return_if_fail() if the
start or end paths passed to it do not correspond to real tree nodes.
However, GtkTreePaths inherently do not have to be valid, so it should
be acceptable to call gtk_tree_selection_select_range() with
non-existent paths. Replace the g_return_if_fail() by a silent return,
and add a unit test.

Don't try to paint onto an error surface. This happens for example when
gdk_cairo_set_source_pixbuf() is called with a pixbuf that is too big
for Cairo to handle.

GPUs generally have problems when you create a 35000px wide surface.
Luckily X catches this and sends a BadAlloc. Which GTK immediately
abort()s on.

If a side of the box is 0px wide, make the corners owned by the adjacent
sides. This avoids spilling over of unwanted colors from the 0-width
side into the corner.
New test for this case is included.
After 3a337156d1 style lookups still used
the parent context's style as the parent style, even though after a
gtk_style_context_save() the root style of the style context is the
proper parent.
Testcase attached.
1) Use font-size instead of color
This makes it easier to compare reference and test because the values
don't change.
2) Actually sort the reference properly
This unbreaks the test.
We recently changed the uppercase licensing text to lower case. The
reference test that checks the contents of the about dialog has to be
fixed to reflect that change.
These turned out to break existing ui files, concretely
GWeatherLocationEntry was no longer guessed correctly.
Update the testcases to reflect this, and add a testcase
for GWeather.
This fixes shadows that are animated not updating the clip of the widget
they are drawn on. An example of this are the buttons in the CSS shadows
example in gtk-demo.

Windows needs a shared library to link the modules against, otherwise
the undefined symbols make it not work.
So build a shared library on Windows.
We don't want a library elsewhere, as that just complicates things, so
we only make the library shared on Windows and keep it as a noinst
library otherwise.
https://bugzilla.gnome.org/show_bug.cgi?id=736338
This is a noinst library for now, but the idea is to turn it into a
proper DLL on Windows, so that we can install it and properly link the
modules to it. Windows doesn't allow undefined symbols in modules.

Just pretend that the main widget is an empty widget the size of the
overlay.
Makes it possible to write testcases where no size requests are run on
overlay widgets before size_allocate() is called.
Testcase included.
with non-installed tests the build would get an empty $(reftestdir)
which would screw up the LDFLAGS.
An rpath seems to be required to make libtool build a shared object.
Without an rpath line, it only builds a static object.

NULL was returned in case of an empty last line. Every users needed to
special-case this. Now it will return the expected result: char_len of 0
with one PangoLogAttr.
In compute_log_attrs(), 'paragraph' will be the empty string "" with
'char_len' == 0.
pango_get_log_attrs() works fine with an empty string, it will return
one correct PangoLogAttr (because there is one text position for the
empty string).
It fixes the unit tests for gtk_text_iter_is_cursor_position().

For functions using _gtk_text_buffer_get_line_log_attrs():

When using the pre-rendered png symbolics it seems that we're off a
tiny bit in a few of the pixels on the antialiased borders of a
stroke. To fix this we switch the icon to media-playback-stop-symbolic
which has no such antialiased borders.
I don't quite understand why the pixels are off, this needs more
research.

Make gtk-reftest consult the REFTEST_MODULE_DIR environment
variable to find out where to look for modules, and fix the
libtool hack to construct the .libs subdirectory correctly.
This was another victim of clipping changes - the labels were
overdrawing each other, leading to test failure. Prevent this
by separating the grid columns.
I found that setting margins to zero makes the textview clip
away some overshooting pixels. So, instead of a 0/10 split,
do this test with a 2/8 split of margins, to avoid the clipping
issue.
This adds a new test which can be scripted to trigger various
event and action sequences, and record state changes in the
accessibility layer.
So far, there are a few tests verifying state changes when
focus changes.

The previous code for computing the clip rectangle forgot to respect
the text-shadow CSS property. This is usually not very visible because
text shadows usually don't extend the ink rectangle by very much.
See attached testcase for an example.
The widget path code copies elements only in gtk_widget_path_copy() -
which is essentially unused - and in
gtk_widget_path_append_with_siblings() - which is used by GtkBox.
So stuff the widget we are testing in a GtkBox to reroduce the problem.
find_by_log_attrs() can return true only in this case:
return moved && !gtk_text_iter_is_end (arg_iter);
So if the iter moved (i.e. something has been found), but is the end
iter, find_by_log_attrs() returns false.
Now the same checks are made in find_visible_by_log_attrs(). The public
functions using find_visible_by_log_attrs() say in their documentation
that false is returned for the end iter, hence the check with
gtk_text_iter_is_end().

attrs[len] is the last PangoLogAttr available, at the iter position after the
last character of the line.
For a line in the middle or the start of the buffer, the '\n' is taken
into account by 'len'. For example the is_word_end is generally reached
before the '\n', not after. But for the last line in the buffer, where
there is no trailing '\n', it is important to test until attrs[len].
The bug didn't occur before because find_by_log_attrs() worked directly
on the iter passed as the function argument. But now it is no longer the
case.
https://bugzilla.gnome.org/show_bug.cgi?id=618852
Do not work with the iter passed as the function argument. Work with
another iter, and set it back to the function argument only if something
has been found.
This fixes a few unit tests. But there are regressions for a few others.

... so that it works with wide separators. Or rather: with separators
that don't request 1px size but any other number. Do that by making the
placeholder request the same size by indeed stuffing (hidden) separators
in it.
Resize grips were introduced for GNOME 3.0, before we had any of the
"new GNOME app" features like invisible borders and CSD. With OS X 10.6
and 10.7, Apple has replaced the classic grips in their applications
with invisible borders as well.
New GNOME app designs don't use resize grips anymore and the new
default theme for GTK+, Adwaita, disables them entirely by forcing their
width and height to 0.
They're past their time. Remove the code to support them. This can
always be reverted if some app relies on them.
