In 9236ee0564 the cups code was updated to use newer API with cups >= 2
and a later commit (a7e207abe) dropped the old code paths and added version
checks in meson/autotools.
The newly used functions were httpConnect2 and httpReconnect2 which are
available since 1.7 and don't require cups 2.0.
Change the versions checks to 1.7 instead so gtk can still be build with
older cups (macOS 10.9 for example, see #1950)
httpGetAuthString() was added with cups 1.3 and we depend on a newer version
now. The direct field access was a fallback in case httpGetAuthString()
was missing, so this can also be dropped.
--api-version returns 1.6 with cups 2.1.0 which breaks the build on
older macOS.
Looking at the upstream git history the value is hardcoded and only randomly
updated as part of cleanup commits, so it looks like it shouldn't be used.
Just use --version instead which gives us the real cups version.
This is a backport of the GdkProfiler from master. It does not include
the pixel bandwidth numbers that come from gdkdrawcontext.c since there
does not seem to be an analog in 3.x.
Additionally, this implements the recent changes for SYsprof's D-Bus
profiler API which adds a Capabilities property and an options hash-table
to the D-Bus interface for forward portability.
getting_started.xml uses relative paths for including code examples
and for some reason the base path is different with meson than with autotools.
Switch both autotools and meson to generate the file and insert the absolute
source path instead.
This also cleans up the content file list: the expand content files have to
be in the content file list as well, so just append them there.
If we detect HarfBuzz and PangoFT2, GtkFontChooserWidget uses them. So
we need to add CFLAGS and LIBS of them to GTK_DEP_CFLAGS/LIBS. If we
don't add them, MinGW build fails to link.
This is for adding a EGL-based renderer which is done via the ANGLE
project, which translate EGL calls to Direct3D 9/11. This is done as a
possible solution to issue #105, especially for cases where the needed
full GL extensions to map OpenGL to Direc3D is unavailable or
unreliable, or when the OpenGL implementation from the graphics drivers
are problematic.
To enable this, do the following:
-Build ANGLE and ensure the ANGLE libEGL.dll and libGLESv2.dll are
available. A sufficiently-recent ANGLE is needed for things to
work correctly--note that the copy of ANGLE that is included in
qtbase-5.10.1 is sufficient. ANGLE is licensed under a BSD 3-clause
license. Note also that Visual Studio 2013 or later is required to
build ANGLE from QT-5.10.1, but the 2013-built ANGLE DLLs can work
without without problems for GTK+ that is built with Visual Studio
2008 or later.
-Build libepoxy on Windows with EGL support enabled.
-Define GDK_WIN32_ENABLE_EGL when building gdk-win32.lib when building
with Visual Studio, or pass in --enable-win32-gles during configure
when building with MinGW/mingw-w64.
-Prior to running GTK+ programs, the GDK_GL envvar needs to contain
gles.
Known issues:
-Only OpenGL ES 3 is supported, ANGLE's ES 2 does not support the needed
extensions, notably GL_OES_vertex_array_object, but its ES 3 support is
sufficient.
-There is no autodetection or fallback mechanism to enable using
EGL/Angle automatically yet. There is no plans to do this in this
commit.
Thanks to LRN for pointing out that we should #include
"win32/gdkwin32.h" instead of #include "gdkwin32.h" for gdkgl.c. LRN
also did the autotools portion of this patch.
Further notes about the autotools --enable-win32-gles option, fom LRN:
This adds --enable-win32-gles option, which enables the
code for GLES renderer. This commit also adds tests for WGL and
EGL in epoxy. The absence of WGL is highly unlikely (it's enabled
by default), but checking for EGL when GLES is enabled is necessary,
as EGL is disabled in Windows builds of epoxy by default.
The header linux/input.h used by GDK is specific to Linux. It is
possible to get a few Linux headers on FreeBSD by installing v4l_compat,
but it is usually better to use the one shipped with FreeBSD.
We prefer dev/evdev/input.h to linux/input.h here, so it will always use
dev/evdev/input.h on FreeBSD regardless of v4l_compat.

This commit adds support the stable version of the xdg-shell protocol.
Support for the last version of the unstable series is left intact, but
will not receive new features.
The stable version is prioritized above the older version.

This IM context implementation goes through the gtk-text-input protocol,
leaving up to the compositor the actual interaction with IM engines. If
the protocol is not offered by the compositor, GTK+ will fallback to the
IMs as specified through GtkSettings.
Both AC_TRY_COMPILE and AC_LANG_PROGRAM put code passed to their second
arguments to the body of the main function. This means that we cannot
and should not declare functions there, or we end up checking whether
the compiler support nested functions instead of whether a compiler or
linker flag is supported.
GCC supports nested functions and tests succeed. Clang doesn't support
nested functions, so tests fail and -fvisibility=hidden won't be used.
This means that functions which are not intended to be used by other
programs, such as gtk_menu_tracker*, gtk_action_observ*,
gtk_menu_muxer_*, become global symbols with default visibility.
GNOME Shell has a private library libgnome-shell-menu.so, which also has
symbols gtk_menu_tracker*, gtk_action_observ*, gtk_menu_muxer_* that are
intended to be used by GNOME Shell itself. When GNOME Shell still used
Autotools build system, the executable gnome-shell explicitly linked to
libgnome-shell-menu.so, so the linker loaded libgnome-shell-menu.so
before libgtk-3.so.0 and GNOME Shell used correct symbols from its
private library.
However, after GNOME Shell switched to Meson build system, gnome-shell
executable no longer lists libgnome-shell-menu.so as its dependency.
Even if we adds it to the build file, it won't be listed in DT_NEEDED of
gnome-shell because Meson uses -Wl,--as-needed by default. This causes
the runtime linker to load libgtk-3.so.0 before libgnome-shell-menu.so
and symbols gtk_menu_tracker*, gtk_action_observ*, gtk_menu_muxer_* are
bound to libgtk-3.so.0 instead of libgnome-shell-menu.so. GNOME Shell
hangs when opening more than one window because it uses functions from
the wrong library.
This problem is already fixed in OpenBSD ports. The article describing
it can be found on OpenBSD Journal with this link:
