KC3 v0.1.17

KC3 is currently a programming language project, inspired by C, Elixir and Common Lisp.
It could be described as C with Elixir modules, pattern matching, and a semantic object system.
The idea is to plug modules, closures, pattern matching, a graph database and
metaprogramming into C11 with a small set of dependencies.

New in this release

• libkc3

  • copying temporary variables for pthread_mutex and pthread_rwlock
    would cause undefined behaviour as per POSIX, this fixes pthread on
    macOS
  • allow for log hooks (a C function callback with a user pointer)
    in the facts database
  • incremental compilation with cached parser results in
    .kc3c files, like Python does. Gives 5x faster loading times
    for all .kc3 files. env_load automatically handles this.
  • fixed a bug in ht_iterator_next where the iterator would not
    go through the first collision list
  • database logging now supports and defaults to binary format
    (marshall + marshall_read)
  • fixed marshall + marshall_read hash table usage
  • str: fixed display of floating point numbers

• Facts

  • Facts.connect/accept allows for bi-directional synchronization of
    an existing Facts.database() over a TLS encrypted connection
    after a successful HMAC-SHA256 shared secret authentication
    challenge/response
  • Facts.accept accepts connections one by one
  • Facts.acceptor_loop starts a thread that calls accept()
    in a loop
  • Facts.acceptor_loop_join() stops the acceptor loop cleanly
  • Fixed hash table lookup in marshall reducing every dump by 30%

• HTTPd

  • allow for configuration of unveil paths in config/unveil.kc3
  • allow for custom log messages in error and request log

• HTTPS

  • HTTPS.Client with libtls and automatic or manual connection
    • GET method
    • POST method
    • JSON response

• JSON

  • fixed parser
    • boolean true or false → Bool
    • map {"key", "value"} → Map %{"key" => "value"}
    • array [1, 2, 3] → List [1, 2, 3]

• RUsage

  • current-process statistics for user and system CPU time, current and
    maximum resident memory, virtual memory, and open files
  • RUsage.stats() returns all statistics in a single map
