KC3 v0.1.17 released

KC3 v0.1.17 was released today.

• https://github.com/kc3-lang/kc3/releases/tag/v0.1.17
• https://git.kmx.io/kc3-lang/kc3/_tree/v0.1.17

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
