When we have an eina.Value_Native (representing an Eina_Value passed by
value) and assign it to an eina.Value (a class with an IntPtr to an
underlying Eina_Value) we copy it so the eina.Value can take ownership
and free the data normally.
A possibly better alternative would be adding an extra flag to
eina.Value (something like OwnsPointer) to check whether we should free
the struct we point to or not.
When transferring the ownership of a ptr(struct) from Unamanaged to
managed, we should marshal the reference-typed fields or they can point
to Managed memory that would make no sense to access from C (for
example, strings would return garbage).
The downside is that it can cause potential leaks if the receiver of the
memory do not free it. In the current state of the EFL api this can
happen in two places:
- Efl.Ui.List.SegArray::remove
return -> ptr(Efl.Ui.List.LayoutItem) @owned
- Efl.Ui.Focus.Manager::fetch
return -> ptr(Efl.Ui.Focus.Relations) @owned
The resources copied by both structs may leak when those functions are
overriden in C# and the values returned to the C code.
Also hide some internal stuff instead of exporting it and generate
implicit conversion operators for struct external/internal.
This commit adds the "documentation" generator, which gets the
documentation_def attribute of the given item and generates xml comments
to be exported by MCS.
For items requiring some customization of the generated comments (e.g.
functions and its parameters), the helpers to generate the preamble
(summary), body (paragraphs) and epilogue (currently just the @since
tag) were added.
Currently we do not support converting Eolian references into xmldoc
references.
As we explicitly generate Get/Set methods for properties, for now the
generator tries to get the get/set specific documentation first. If it
is not present, fallback to the common docs.
Later this could be changed to generate the common one as paragraphs of
the Get/Set.
Also some generated code like the wrappers for calling C# methods
from C can be private. This will cleanup the introspection results
and warnings when generating documentation.
Due to this visibility change, the binbuf tests had to be changed
to add redirect calls to the native methods instead of directly
calling the DllImport'd methods.
Fix several integer binding type deduction based in its size on C.
Generation for function pointers no longer use modified argument name
which is different from the parameter name.
New generation context for structs.
bool from UnmanagedType.I1 to UnmanagedType.U1 (correct use
inside structs according to mono documentation).
byte (signed char) and int8 now is correctly represented by
sbyte in C#.
Check parameter direction in some out generators in parameter.hh.
Add efl_libs.csv to gitignore.
Make eina.Value pointer constructor public.
Add missing fields to efl.kw_event.Description struct.
Remove eina.File workaround (let struct gen handle it).
Remove is_function_ptr bool from regular_type_def and
add a typedecl_type enum to it. Also add some helper
methods for easier comparison.
Left some test cases commented for when pointer parameters
are properly working.
Instead of messing around with varargs, create individual wrappers for
each type supported.
The va_list approach was getting problems with float/double on Windows.
