Partially needed to avoid build breakages because Corrade itself
switched as well, partially because a cleanup is always good. Done
except for (STL-heavy) code that's deprecated or SceneGraph-related APIs
that are still quite full of STL as well.
This means I (and people making their own plugins) don't need to go and
update each and every plugin once the version in the interface string
gets bumped after a (silent) ABI break. Such as when new virtual
functions get added, as those often lead to strange crashes if the
plugins don't get rebuilt after.
The plugins will now use this macro, which means they'll
automatically embed an interface string that was present in the base
class header at build time. However, when the base class updates, the
previous string is still embedded in the plugin binary, which will then
fail to load -- this being automatic doesn't mean the original purpose
is lost. Subsequently rebuilding the plugins from source will make them
pick up the updated interface string again.
This is what commit ca722eac6e should
have been.
Sorry for breaking a non-deprecated MSVC build once again. The reason it
"appeared to work" for me was that on deprecated builds, Manager.h
includes Manager.hpp for backwards compatibility. On non-deprecated it
doesn't and MSVC ends up dying on a linker error. But the problem was
not related to extern templates, the problem was that there was a
compiler-specific ifdef in the cpp file which exported the class for all
compilers but MSVC, somehow. And so when I removed extern template from
the header, it still worked everywhere, except MSVC and except a
non-deprecated build.
Hey, do you also remember the times where people were excited to upgrade
from Clang 3.6 to 3.7, GCC 4.7 to 4.8 or Firefox 1.1 to Firefox 1.5? Not
Clang 12 to 14, GCC 10 to 13 or Chrome 102 to 126.
Here the benefit is especially clear -- as Containers::Pair is trivially
copyable with trivial types, all growable arrays can make use of
std::realloc() while with the STL variant a silly constructor, copy
constructor, destructor had to be used.
Additionally, we no longer need to take explicit care of libc++ and MSVC
STL where returning a std::pair<bool, Containers::String> as
return {{}, Containers::String{..., <deleter>}};
would caused an unnecessary copy instead of a move, losing the custom
deleter in the process. Yay!
There's a <Corrade/Containers/PairStl.h> include for backwards
compatibility purposes, but obviously it would only work for the return
type of validate*() and cases where an initializer list was passed to a
list-of-pairs-taking functions, and not a concretely typed ArrayView.
Those functions were though mostly the linker API which isn't
implemented by any plugin yet, so it shouldn't be *that* breaking to
users. Neverteless, I'm trying to do this breaking change rather sooner
than later to prevent pain further down the road when the Vulkan APIs
and SPIR-V pipeline gets widely used.
Consistently with changes done to Utility::Path, this enforces proper
error handling on user side. Originally I didn't want to do this and
instead wanted to have a special Array instance devoted for an error
state, but that still would allow the error state be errorneously
treated as a successful but empty array.
There will be Flag::FlipY for images at some point, enabled by default
for compatibility with existing GL code, and so it makes sense to start
discouraging setFlags() as early as possible to avoid people resetting
the default by accident.
Also update the imageconverter, sceneconverter and shaderconverter utils
to use these instead of setFlags().
