TpBaseConnection has to support it for backwards compatibility.

Also make use of TP_DISABLE_DEPRECATED consistent: always wrap
deprecated functions, and add deprecation decorators to any wrapped
function.

Do we really still need TP_DISABLE_DEPRECATED? It doesn't seem that much useful with these macros; maybe we can drop it in next.

Comment 20 Guillaume Desmottes 2012-05-03 00:34:24 UTC
We should at least annotate the new 0.19 API for MAX_ALLOWED.

Btw, would it be possible to raise an error during 'make check' if a new API is added without its version annotation?

It already went away.

(In reply to comment #13)
> Do we really still need TP_DISABLE_DEPRECATED?

It's the only way to "deprecate" macros (and typedefs/enums, unless we add a gcc-specific version of _TP_DEPRECATED_IN_x_y), and it seems sensible to make it act on everything.

_TP_DEPRECATED and _TP_DEPRECATED_IN_x_y (and the GLib macros they're based on) are portable (to at least MSVC), but have to appear before a function; they can't appear after, and can't go on typedefs or enums or whatever.

(In MSVC they're implemented as __declspec(deprecated) or something, which can only appear on extern symbols - ABI, not API.)

_TP_GNUC_DEPRECATED (and the GLib macro it's based on) is gcc-only, but more flexible.

None of those work on macros, because macros are expanded before the compiler gets involved.

(In reply to comment #20)

Yes. May I merge this lot first?

I can't think of an easy way to do so. I don't want to write yet another semi-working C parser (we run two of those already, in gtk-doc and g-i).

Sure, go for it.

Yeah I was suspecting that. :\


Looks good to me.

---

This will be needed for the _TP_AVAILABLE_IN_UNRELEASED macro. We can use the usual "grep for UNRELEASED" to replace that with _TP_AVAILABLE_IN_0_20 before release.

I mostly believed the Since: annotations, although I did fix a couple that were clearly wrong (TpDBusChannel and tp_account_dup_storage_specific_information_vardict_finish).
