v0.16.0

Primarily addition of simplified TCP reconnection, related fixes and functionality.

Added

• Add .close() and .reconnect() on TCP client actor [#1383]
  • It is now possible to explicitly close or reconnect a TCP client
• Add RTS Monitor actor in acton.rts.Monitor() [#1383]
  • The RTS Monitor actor starts a worker monitor per worker thread, each pinned
    to a particular worker thread. By doing so, it can retrieve information from
    each worker thread in safe manner, honoring the RTS design.
  • Currently just supporting getting handles from I/O subsystem.
• Add env.nr_threads [#1383]
• Add set_actor_affinity(wthread_id) [#1383]

Changed

• Include DNS query hostname in on_error cb [#1382]
  • Simplifies retrying a query since we otherwise do not have a persistent
    tracking object per query

Fixed

• Fix --rts-debug [#1383]
  • Has been broken since new builder but is now fixed
• Fix off-by-one in worker thread wake up [#1383]
  • Waking all threads would not consider all threads as there was an off-by-one
    error.
  • No known problems in the field from this, it was only noticed in development
    using --rts-wthreads=1
    • The RTS uses at least 4 workers per default
• Use relative source file path in logs [#1383] [#1391]
  • __FILE__, set by the C compiler, is used to include source file path in
    log messages
  • Zig uses absolute paths to all files
  • now using -ffile-prefix-map to make path relative
  • project dir name also included, for example base/rts/rts.c, to make it
    easier to understand from which project a file comes from
• Assignment in multiple branches [#1390] [#1392]
  • Only assigning in multiple branches (not before branches) would lead to
    redefining shadowing variable of outer scope in low level generated C code
  • Info guiding joined assignment has been fixed

Testing / CI

• Verify we cannot instantiate WorldAuth
