This page is a collection of API changes we intend to make as soon as we drop BeOS backward compatibility. Feel free to add comments concerning any API removal/change/addition to be done.

---

General:

• Redo shared libraries: there should be one library per kit and corresponding names for each. (possible conventions are "libsupport.so", "libSupport.so", "libSupportKit.so")
• Stop supporting the GCC2 ABI
• Switch to LLVM?

POSIX:

• Drop stat_beos in favor of stat.
• More breakage to fully switch to a 64-bit time_t (there is one syscall that needs to be tweaked, and 32-bit Haiku is still on 32-bit time_t)
• Replace glibc (use parts of musl? it's MIT licensed).
• Multiuser! (some general things that need to be cleaned up at the same time: ​Tracker's ConfirmChangeIfWellKnownDirectory).
• Get rid of R5 compat stuff in Network Kit.

Application Kit:

• Integrate the functionality of BInvoker::InvokeNotify() into BInvoker::Invoke().

Support Kit:

• Replace BAutolock with a proper template based AutoLocker, like the one we have in shared already.
• convert_encoding_open() convert_encoding_close() with respect to UTF-8, #976 (or perhaps drop textencoding altogether and create a ByteArray class in the Support Kit that can handle encodings?)

Interface Kit:

• Derive BView from BLayoutItem and drop BViewLayoutItem?
• Remove GetPreferredSize() from BView and child classes in favor of PreferredSize() (however, this would mean all classes which override PreferredSize would have to use ComposeSize...)
• Remove copy constructors on BRect, rgb_color and other small classes that do not need it, so they can be passed in registers.
• Create a model/view infrastructure for the column list view and OutlineListView. (see Debugger's MVC wrapper over current CLV) (maybe look at Qt's [rejected] Model/Views 2.0?)
• BAlerts should be layout-aware along with all other rich text views.
• All rich text views should accept (simple) style markup as input and as output (maybe HTML).
• Add a BToolbar API (the currently-shared BToolBar should be a good basis, it needs support to add arbitrary BViews)
  • Also need standard icons resources, probably following ​FreeDesktop's spec.
• Cleanup BTabView -- get rid of the non-layout version. (Terminal may need a rewrite...)
  • Decouple tab label from its name.
• Don't eat all Cmd key combos even if they don't have any action assigned.

Media Kit:

• The API uses add_on and AddOn, but also addon - the latter should be faded out.
• Get rid of R5 compatibility stuff (and R3 (!) compatibility stuff).

Tracker:

• FilePanel does not use layouts due to ​the Be Book's recommendation for developers to mess with the layout if they needed to.
