BUGS

Windows specific

  • Windows apparently doesn't return file modification times correctly on local hard drives (GetFileTimes()). Thus the existance of file_name_watcher.

  • Be careful not to forget the respective compiler flags when using threads! Consult your compiler's documentation as to which parts of C++ are implemented thread-safely and which aren't.

Future directions / TODO

  • Documentation: Extract the comments from the header files and put them in a printable document.

  • Streamline the testing system and add a script that automatically runs the unittests.

  • Use more C++11/C++14 features as they become available, e.g. <random>

  • Make sure that floating point random numbers from std::random are deterministic across platforms (they're used a lot in tests!). Better yet, make test outcomes independent of concrete random number sequence.

  • Refactor convert()/check_... etc. in registry.h. Too much overloading is going on. Name T const& convert( any& ) extract. Name the template convert_template().

  • Factor out crypt streambufs? Stateful reader/writer classes generalizing streambuf_traits?

  • Replace symlinks by different include paths?

  • Revamp error handling: general throw_os_exception() function based on last error or strerror_r(), resp. Get rid of STRERROR_CHECK().

  • Consolidate realtime stuff: Multiple schedulers should be possible with POSIX1B (cf. timer_create(), 2.4, etc. in SUSv3). itimer-based: should be singleton. itimer-based: SIGARLM will be blocked only for current thread, therefore have to instantiate it before any threads are created! Check blocking semantics for realtime signals (maybe they're blocked by default?).

  • Implement serial interface classes on systems other than Windows.

  • Write <cctype> overloads for signed/unsigned char. Used in util.h and registry.cpp. Alternatively, document ASCII only.

  • Add an AES implementation.

  • Templatize table<> on index type?

  • Logger: Base on varlist (currently, code is duplicated).

Networking specific

  • Implement performance preferences?

    See Java implementation: http://java.sun.com/j2se/1.5.0/docs/api/allclasses-frame.html

  • Avoid/ignore SIGPIPE on socket write on Windows and other systems (it is implemented on Linux and Darwin/FreeBSD). Unfortunately, there doesn't seem to be a portable (POSIX) way to do that.

  • Optimize UDP implementation: Avoid buffer copies in case of contiguous ranges.

  • Check defaults for address reuse and broadcasting in all constructors.

  • shutdown(): Remove unnecessary shutdowns (e.g. if other side already has shut down). Try to do this without a stateful socket reader/writer class, if at all possible (thread safety!).

  • Implement iowait() (multiplexing).

  • Implement the exception hierarchy from N1925.

  • Put it into std::tr2.

  • More example code.

Feature requests

  • Lexer: Support for different line ending styles recognized on the fly?

  • New registry::read_from() overloads with descriptive parameters (throw on redefinition...). Integrate the flag with grammar?

  • Registry: extend to expression parsing (similar to Mathematica parser).
