Items we (currently) plan to finish in the ptrace(2) field:
- verify ppid of core dump generated with PT_DUMPCORE
it must point to the real parent, not tracer
- adapt OpenBSD regress test (regress/sys/ptrace/ptrace.c) for the ATF context
- reiterate over FreeBSD tests and add missing ones if applicable
- add PT_DUMPCORE tests in the ATF framework
- research kevent support for tracing a process over a file descriptor,
this means alternative to wait(2)-based events with passing events over the
kqueue API - signal handlers are global per application and they clash with
GUI toolkits (and perhaps other libraries) - this is long term wishlist in
GDB for Linux - the current approach is to fork and debug through GDB remote
protocol (this is how it is done in LLDB)
- add ATF tests for SIGCHLD
- research kgdb(4)
and of course: fix as many bugs as possible.
Features in ELF, DWARF, CTF, DTrace are out of scope of the above list.
