Summary:
Patch from a series of patches to rename EAPI symbols to specific
library DSOs.
= The Rationale =
This patch is from a series of patches to rename EAPI symbols to
specific library DSOs.
EAPI was designed to be able to pass
`__attribute__ ((visibility ("default")))` for symbols with
GCC, which would mean that even if -fvisibility=hidden was used
when compiling the library, the needed symbols would get exported.
MSVC __almost__ works like GCC (or mingw) in which you can
declare everything as export and it will just work (slower, but
it will work). But there's a caveat: global variables will not
work the same way for MSVC, but works for mingw and GCC.
For global variables (as opposed to functions), MSVC requires
correct DSO visibility for MSVC: instead of declaring a symbol as
export for everything, you need to declare it as import when
importing from another DSO and export when defining it locally.
With current EAPI definitions, we get the following example
working in mingw and MSVC (observe it doesn't define any global
variables as exported symbols).
Example 1:
dll1:
```
EAPI void foo(void);
EAPI void bar()
{
foo();
}
```
dll2:
```
EAPI void foo()
{
printf ("foo\n");
}
```
This works fine with API defined as __declspec(dllexport) in both
cases and for gcc defining as
`__atttribute__((visibility("default")))`.
However, the following:
Example 2:
dll1:
```
EAPI extern int foo;
EAPI void foobar(void);
EAPI void bar()
{
foo = 5;
foobar();
}
```
dll2:
```
EAPI int foo = 0;
EAPI void foobar()
{
printf ("foo %d\n", foo);
}
```
This will work on mingw but will not work for MSVC. And that's why
LIBAPI is the only solution that works for MSVC.

Using a new architecture in the generated files that simplify multiple
inheritance and allows the use of interface types as parameters.
No longer using a hand-crafted C++ header for eo_base.eo.
This file was added to the generation process.
Updated all files that are dependent in the hand-crafted eo_base
C++ header.
Now there is a class that contains the essentials functions of the former
eo::base wrapper and that is used to create (through inheritance) the
"concrete" classes for all Eo generated wrappers.
No longer binding any function or property that are protected, private or
legacy for now.
eolian_type_instance is now a struct with general information for the
whole type.
Added the new header file namespace_generator.hh to hold namespace
generation grammars.
Separated declaration and definition of Eo wrappers methods.
Referring for most objects by its full name (starting at the global
namespace ::) in the generated files.
Created additional helper grammars to avoid code replication.
Removed a TODO comment referring to a doubt about inheritance of
constructor methods.
Added a TODO comment regarding memory allocation for callbacks in static
member functions.
Added static assertion in the generated header to ensure that the wrapper
have the same size of Eo*, thus grating compatibility between these types.
Added static assertion in the generated header to ensure that the wrapper
have standard layout. This should ensure correct type sizes when dealing
with inheritance.
Created a test to ensure that eo::base and the eolian wrappers have the
same size of a Eo*.
Added eolian_cxx_test_wrapper.cc to the list of test source files in
Makefile_Eolian_Cxx.am.
