+ This 43rd release of NuttX was made on September 16, 2009 and is available for download from the + SourceForge website. The change log associated with the release is available here. Unreleased changes after this release are available in CVS. These unreleased changes are listed here. + This release of NuttX incorporates the verified port of Jeff Poskanzer's THTTPD HTTP server. + Many of the key features of THTTPD have been tested on the Micromint Eagle-100 development board (Cortex-M3). + These tests verify:
- 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: -fileno, strstr,
- strpbrk, fcntl).mktime, gmtime, gmtime_r,
- gettimeofday, localtime, localtime_r, and
- strftime)recvfrom and accept now work with non-blocking
- sockets.exec)
+ 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.
-nuttx-0.4.10 2009-08-08 Gregory Nutt <spudmonkey@racsa.co.cr> - - * lib/: Added some basic regex-subset, pattern matching functions - * lib/: Greatly simplified mktime() and gmtime_r(). The Gregorian and - Julian time calculations were interesting, but not necessary in the - typical embeddd system. - * sched/: Added gettimeofday(). This implementation is simply a thin - wrapper around clock_gettimer(). - * lib/: Add gmtime(), localtime(), and strftime() - * binfmt/: Add exec(). This is just a wrapper that executes both - load_ and exec_module() in a more familiar manner. It is not consistent - with more standard exec() functions, however, because (1) it returns - and (2) it requires symbol table arguments. - * lib/: Add fileno() - * examples/ostest: Several of the tests used a big, hard-coded stack size - when creating test threads (16Kb stacksize). The stack size should - be controlled by the .config file or the OSTest won't work on platforms - with memory constraints. - * netutils/thttpd: An initial port of Jef Poskanzer's THTTPD HTTP server. - See http://acme.com/software/thttpd/. - * examples/thttpd: A basic test program for THTTPD - * configs/eagle100/thttpd: A build configuration for THTTPD on the Micromint - Eagle-100 LMS6918 (Cortex-M3) board. - * configs/ntosd-dm320/thttpd: A build configuration for THTTPD on the Neuros - DM320 platform. - * lib/: Added strstr() and strpbrk(). - * net/recvfrom.c and net/accept(): Sockets now support some non-blocking - operations, specifically for (1) TCP/IP read operations when read-ahead - buffering is enabled, and (2) TCP/IP accept() operations when TCP/IP - connection backlog is enabled. - * fs/fs_fcntl.c and net/net_vfcntl.c: Minimal support provided for fcntl(). - It can, at least, be used to mark sockets as blocking or non-blocking. - * net/net_close.c: Fix bug in close(). If reference count not set to zero - then uip_tcpfree() will assert when DEBUG is enabled. - * net/accept.c: Fix bug in accept(). The logic expected parts of the - return address structure to be initialized or it would return an error. - -pascal-0.1.2 2008-02-10 Gregory Nutt <spudmonkey@racsa.co.cr> - - * Add logic to build and link with the ZDS-II toolchain - use with the z16f. - * Make sure that POFF header structures are aligned - * Standardized POFF file format to big-endian - * Break up large switch statements to lower complexity - and eliminate a compiler bug - * Changes so that runtime compiles with SDCC. - -buildroot-0.1.7 2009-06-26 <spudmonkey@racsa.co.cr> - - * configs/avr-defconfig-4.3.3: Added support for AVR to support a NuttX - port of the ATmega128. - * toolchain/nxflat: Added logic to build NuttX NXFLAT binding support tools - * toolchain/genromfs: Added support for the genromfs tool -- -
