This release contains major API additions and harmonization of the API
modeling. The latter causes breaking changes.
Bugfixes
- fix bad value for SignalNr::TERM_STOP.
- fix inconsistent state in SubProc when child is killed by a signal.
- fix bugs in the error handling of the pthread API.
Filesystem
- added support for access() and faccessat().
- added support for flock() API.
- added file locking operations in FileDescriptor.
- added for asynchronous signal-driven I/O in FileDescriptor.
- added support for file lease support in FileDescriptor.
- renamed TYPE_MASK and MODE_MASK enum values to avoid preprocessor macro name clashes on some GCC toolchains (e.g. Ubuntu arm cross toolchain).
Signals
- support for sending thread-directed signals.
- add pause() wrapper.
- add sigqueue() variant for sending signals.
- support sigsuspend().
- full support for asynchronous signal handling via sigaction()
harmonize process state information by fully wrapping siginfo_t. This type
is now used in cosmos::proc::wait() as well in asynchronous signal handling
and cosmos::proc::wait_info() and some other locations. This replaces
WaitRes, which was only a partial special-purpose wrapper over siginfo_t.
- added wrapper for sigaltstack().
Threads
- use dedicated ThreadID that is distinct from ProcessID.
ptrace() API
- basic wrapper around the ptrace() ioctl like call
more advanced type safe class Tracee which covers the individual ptrace requests in a type safe way
