The general part stays in the root namespace, while the GL-specific
stuff goes to the GL namespace. Also all GL-specific documentation was
moved to relevant APIs in the GL namespace. This finally allows me to
build PixelStorage.cpp as part of the root namespace.
The PixelStorage::pixelSize() function and
PixelStorage::dataProperties() taking a pair of GL::PixelFormat /
GL::PixelType enums is deprecated, use GL::pixelSize() and
dataProperties() taking pixel size directly instead. A lot of code is
still using these, including images; the deprecated aliases are inlined
in the header to avoid a compile-time dependency on the GL library.
At the moment just the GL library itself w/o the tests, and without
backwards compatibility aliases. The following types were left in the
root namespace, despite being in the GL/ directory, as they will get
moved back soon:
* Image, CompressedImage and their dimensional typedefs
* ImageView, CompressedImageView and their dimensional typedefs
* PixelStorage
Not PixelFormat etc., that one will stay in the GL namespace and a
completely new PixelFormat enum will be provided in the root namespace.
This will later enable conditional compilation of APIs that depend on
the GL library (for example the Text library directly producing compiled
meshes instead of just plain vertex data).
Minimal updates (just the include guards) so Git is hopefully able to
detect the rename and track the history properly.
Everything except Magnum::GL doesn't compile now.
More consistent with what's done elsewhere, reduces header dependencies,
allows me to (later) make this independent on the AL library and also
works around a Doxygen bug. Win win!
The current testing workflow had quite a few major flaws and it was no
longer possible after the move of Any* plugins to core. Among the flaws
is:
* Every plugin was basically built twice, once as the real plugin and
once as a static testing library. Most of the build shared common
object files, but nevertheless it inflated build times and made the
buildsystem extremely complex.
* Because the actual plugin binary was never actually loaded during the
test, it couldn't spot problems like:
- undefined references
- errors in metadata files
- mismatched plugin interface/version, missing entry points
- broken static plugin import files
* Tests that made use of independent plugins (such as TgaImageConverter
test using TgaImporter to verify the output) had a hardcoded
dependency on such plugins, making a minimal setup very hard.
* Dynamic loading of plugins from the Any* proxies was always directed
to the install location on the filesystem with no possibility to
load these directly from the build tree. That caused random ABI
mismatch crashes, or, on the other hand, if no plugins were
installed, particular portions of the codebase weren't tested at all.
Now the workflow is the following:
* Every plugin is built exactly once, either as dynamic or as static.
* The test always loads it via the plugin manager. If it's dynamic,
it's loaded straight from the build directory; if it's static, it
gets linked to the test executable directly.
* Plugins used indirectly are always served from the build directory
(if enabled) to ensure reproducibility and independence on what's
installed on the filesystem. Missing presence of these plugins causes
particular tests to be simply skipped.
* Plugins that have extensive tests for internal functionality that's
not exposed through the plugin interface are still built in two
parts, but the internal tests are simply consuming the OBJECT files
directly instead of linking to a static library.
Too much burden to implement. Nope. Sorry. All APIs were just asserting
that it's not enabled at the moment, so I may as well just remove it
completely.
Statically built plugins get imported automatically when using CMake 3.1
and newer. Otherwise simply #include a corresponding
importStaticPlugin.cpp file.
