The Windows backend produces full, multithreaded backtraces. When
DrMingw is available, it also provides full symbol and (where
available) source-location information. Otherwise, it provides
symbol information for most of our libraries, but not for the GIMP
binary itself.
GimpBacktrace provides an interface for creating and traversing
multi-threaded backtraces, as well as querying symbol information.
While we already have some backtrace functionality, it relies on
external tools for the most part, and as such is rather expensive,
and is only meant for producing opaque backtraces. GimpBacktrace,
on the other hand, is meant to be relatively cheap (we're going to
use it for profiling,) and allow inspection of the backtrace data.
In the future, it might make sense to replace some, or all, of the
other backtrace functions with GimpBacktrace.
GimpBacktrace currently only supports Linux. By default, it uses
dladdr() to query symbol information, which is somewhat limited (in
particular, it doesn't work for static functions.) When libunwind
is installed, GimpBacktrace uses it to get more complete symbol
information. libunwind is currently an optional dependency, but it
might make sense to promote it to a mandatory, or opt-out,
dependency, as it's lightweight and widely available.
On other platforms, the GimpBacktrace interface can still be used,
but it always returns NULL backtraces.
The jpeg_save_markers API has existed since 27th March 1998! So it's
safe to assume that everybody has it, and there's no need to check for
it.
libjpeg-turbo has had a libjpeg.pc since 2016, and the IJG's software
has it too. Dropping support for old libraries is a small price to pay
for the benefits of a simpler build.

We don't need to commit PNG symbolic icons as `gtk-encode-symbolic-svg`
is perfectly able to generate them from the SVG.
Moreover its man says that it makes "specially prepared png files",
whatever that means. So I don't think we should just rename our
self-exported PNG files as '*-symbolic.symbolic.png'. It is better to
generate them with this tool.
Note that I am now splitting icon-list.mk into 2 files. This is only a
temporary stepback, as I am actually going to merge the 2 icon themes
into one very soon, and hopefully we should be able to generate the list
to ensure we don't miss an icon.
Anyway the icon lists had already diverged earlier, even though it was
only all still in a single file.
... Windows installation of GIMP.
Our default installer installs 32-bit version of the various DLLs in
32/bin/ (under the installation prefix). Currently this additional
folder is simply added in the PATH, so it works most of the time.
Unfortunately the PATH is searched last for DLLs, and in particular, it
is searched after system directories. So it means that if any misbehaved
application is installing DLLs in system dirs (and in particular
incompatible/older versions of the same DLLs a GIMP plug-in uses), it
breaks the 32-bit plug-in.
SetDllDirectoryW() bypasses this order and the set folder is searched in
between the binary directory and the system dirs. We were already
setting this for our main bin/ directory, which was good for 64-bit
plug-ins, but this was not protecting 32-bit plug-ins. Now our code to
run plug-ins check the bitness of the executable before running it, and
updates the DLL folder accordingly.
The alternative 32-bit folder can be overridden by the configure option
--with-win32-32bit-dll-folder (default: 32/bin/). This option can only
be set when building for 64-bit Windows obviously.
Alternatively we could have put copies of 32-bit DLLs in a subfolder
with each 32-bit plug-in, but this is at best a terrible workaround, as
we would duplicate DLLs for every such case. And this would not have
protected third-party plug-ins which wish to use some of our DLLs.
Last alternative is to use AddDllDirectory(), but it works since Windows
7 with a given update only. And our current official support is any
Windows since Windows 7. So we don't want to use this right now (also
I'm not sure it would actually be much better than current
implementation, and it seems to have a bit more limitations than
SetDllDirectoryW(), though I have not tested).

Debugging stable versions under Windows is a pain because we don't have
access to the standard outputs. The debug console is indeed only built
on unstable builds. Let's make the debug console a separate build option
to allow building stable versions for debug (obviously the default
behavior when not configuring, is same as before, i.e. stable without
console and unstable with console).
(cherry picked from commit 1a28878943)
AM_PATH_GLIB_2_0 m4 macro actually computes this value using
$PKG_CONFIG. Yet $PKG_CONFIG variable is the pkg-config tool looking for
target libraries (not host), hence it would return the executable
`glib-compile-resources` built for the target.
Also using the same variable name invalidates our test: our own
AC_PATH_PROG was never run as the variable was already set. And no
environment variable could override this test anymore either. This is
why I rename the test variable to HOST_GLIB_COMPILE_RESOURCES.

Back when I implemented this as a recommendation, gettext 0.19 was not
even out yet. Nowadays it is in Debian Testing (Debian Stable even!), so
it makes no sense to continue just "recommend" it, especially as it was
breaking script-fu localization.
See old commit feb1bf2797.
Right now it only loads AppStream data, which is completely useless, yet
is a base of a managed extension system. Having proper metadata is what
will allow to actually know what is installed.
This is only the first draft.
Note that I am not adding the extension path into GimpCoreConfig on
purpose, since the point is not to have people manage their extension
directories manually anymore.
The extensions will be loaded from the build-time system path or the
config directory, and that's all.
What will probably be stored in the config though will be the remote
repositories URLs (allowing third-party extension repositories).
... --enable-relocatable-bundle option.
This will allow to use this option for more than MyPaint brushes. For
macOS and Windows, we default to "yes" and "no" for other OS, though it
is always possible to set an explicit value.
This is the minimum set of changes needed to update help-browser to the
WebKitGTK+ 2 API. Fortunately, the plug-in did not use parts of the old
API which would have been difficult to port (DOM bindings, for example),
and therefore the code translates quite well to the new API. The main
differences are:
- WebKitWebFrame is gone, most of its methods are now in WebKitWebView.
- Searching for text inside Web pages has to be done now through the
WebKitFindController object.
- Checking whether there is selected text that can be copied now goes
through WebKitEditorState.
- The WebKitWebView::title-changed signal is no more, the callback is
connected to notify::title instead.
- The load-started and load-finished pair of signals are now merged
into WebKitWebView::load-changed.
- There are no methods to zoom a WebKitWebView in and out, instead
the zoom-level property is set. The updated code ensures that the
zoom lovel stays inside the [0.1, 10.0] range.
- Page visit history now goes through WebKitBackForwardList.
The updated plug-in was successfully built in tested with WebKitGTK+
version 2.20.3.
Commit b2df13749c disabled building
devel-docs and pygimp in the makefiles, but their makefiles are
still generated by configure, which breaks distcheck, because the
necessary Makefile.in files are missing from the tarball.
Comment out the skipped files in configure.ac too.
These were mostly kept for scripts which needed to keep working. Since
we don't ensure compatibility anymore, let's just get rid of old
deprecated data.
These are not working anymore since we now need CSS themes.
Also we'll prefer to use theme variants anyway.
I also remove a remnant of the old "Small" theme, which was not
installed anymore anyway, and is not useful anymore.
We have this problem with flatpak that the common directory
("/usr/share/color/icc") is not visible from inside the sandbox. With
proper permissions, it is actually accessible, yet the host's /usr is
mounted at /run/host/usr/.
Since sandbox systems are getting more common, we need to make this path
customizable. I am therefore adding a --with-icc-directory configure
option to change the default color profile folder at build time.

We get a lot of packaging bugs for third-party builds in our tracker,
especially since our debug tool now opens directly our bug tracker.
It would be preferred if third-party packagers were to make a first
filtering of bugs and only reported once they knew for sure that the bug
is in core code, and not in packaging.
Our configure script will now propose a --with-bug-report-url option
allowing to set a different web address. This address will be the one
opening in the debug dialog.
