- The changes in thsi release focus on the port of Jeff Poskanzer's - THTTPD to NuttX. - Do to limited time to work on NuttX, that port is still not fully functional. - However, numerous related bug-fixes and functional additions for THTTPD were - added: -
    -
  • Several new standard C-library functions (fileno, strstr, - strpbrk, fcntl).
    • -
  • Improved and extended timing APIs (mktime, gmtime, gmtime_r, - gettimeofday, localtime, localtime_r, and - strftime)
    • -
  • Networking enhancements: recvfrom and accept now work with non-blocking - sockets.
    • -
  • NXFLAT extensions (exec)
    • -
  • Pattern matching logic.
    • -
  • And miscellaneous bug fixes (see the ChangeLog for a complete list).

    +
  • Serving of files from any file system, and
    • +
  • Execution of CGI executable. + This release supports execution of NXFLAT executables residing on a ROMFS file system. +
+

+ A standard CGI interface is used: Information is pasted to the CGI program via POST commands and via environment variables. + CGI socket I/O is redirected to stdin and stdout so that the CGI program only need to printf() to send its content back to the HTTP client. +

+

+ Another value to this THTTPD integration effort has been that THTTPD has provided a very good test bed for finding NuttX networking bugs. + Several very critical networking bugs have been fixed with this 0.4.11 release (see the ChangeLog for details). + Networking throughput has also been greatly improved. + Anyone using NuttX networking should consider upgrading to this release.
