Release Notes

0.9.3

  • close with event for TCPSocket is now publicly accessible
  • RunLoop instance now contains public instance of Random with the name rnd
  • some linter warnings removed from code
  • CRC32 and CRC32C added to crypto algorithms

0.9.2

  • fixed bug when HTTP Time header was cached by server for 500 seconds, not milliseconds
  • example of fair resource-bound API server. TODO - improve example
  • SignalStop renamed to Signal and now accepts list of signals. Empty list means to detect generic Ctrl-C and sorta works on Linux, Mac and Windows.
  • crab::Thread to wrap creation of std::thread with RunLoop and perform raceless cancellation
  • Recommended Random seeding
  • Web Socket masking is now 8x faster
  • MD5 added to crypto algorithms

Bugs fixed

  • sigprocmask was changed pthread_sigmask, so that Signal work in multithreaded apps

0.9.1

Low level

  • optional moved out of details namespace, tiny fix in optional

Bugs fixed

  • When setting socket options to 1, they were set to uninitialized value instead. Worked because luck plus true = anything non-zero.

0.9.0

Low level

  • Experimental TLS code (not for use in a wild yet)
  • Simple crab::optional for using older C++ standard
  • Random is adapted to std containers

HTTP

  • Streaming of HTTP bodies (both upload and download)
  • New HTTP URI parser by AK

Bugs fixed

  • WebSockets now support control frames between message chunks

Incompatible changes

  • New callbacks design for WebSockets and postponing normal HTTP responses
  • Stricter integer parser might break existing products

0.8.0

Low level

  • New expeimental low-level implementation added, CRAB_IMPL_LIBEV over libev (requires sudo apt install libev-dev).
  • CFRunLoop low-level implementaion merged (partial support for TLS for now, full support is expected in near future).
  • crab::Random now uses PCG32 instead of std::mt19337. Slow construction and number generation of std::mt19337 consumed too much CPU for lots of very short Web Messages.

HTTP

  • To avoid some NATs disconnecting Web Sockets, OPCODE_PING is sent every 45 seconds (Timeout selected to be a bit less than TCP keepalive, which is 50 seconds for major browsers)
  • New HTTP Query parser by AK
  • New HTTP Cookie parser by AK

Bugs fixed

  • HTTP socket shutdown was performed incorrectly for some HTTP/1.0 clients

Incompatible API changes

  • sha1 and base64 moved into crab namespace

Before 0.8.0

ReleaseNotes.md is new in version 0.8.0. Before that, commit history served as a release notes.
