/*
* Wed Apr 17 16:05:29 EDT 2002 (James Roth)
*
* - Fixed an unlikely sys_thread_new() race condition.
*
* - Made current_thread() work with threads which where
* not created with sys_thread_new(). This includes
* the main thread and threads made with pthread_create().
*
* - Catch overflows where more than SYS_MBOX_SIZE messages
* are waiting to be read. The sys_mbox_post() routine
* will block until there is more room instead of just
* leaking messages.

*/
/**
* @page pitfalls Common pitfalls
*
* Multiple Execution Contexts in lwIP code
* ========================================
*
* The most common source of lwIP problems is to have multiple execution contexts
* inside the lwIP code.
*
* lwIP can be used in two basic modes: @ref lwip_nosys (no OS/RTOS
* running on target system) or @ref lwip_os (there is an OS running
* on the target system).
*
* Mainloop Mode
* -------------
* In mainloop mode, only @ref callbackstyle_api can be used.
* The user has two possibilities to ensure there is only one
* exection context at a time in lwIP:
*
* 1) Deliver RX ethernet packets directly in interrupt context to lwIP
* by calling netif->input directly in interrupt. This implies all lwIP
* callback functions are called in IRQ context, which may cause further
* problems in application code: IRQ is blocked for a long time, multiple
* execution contexts in application code etc. When the application wants
* to call lwIP, it only needs to disable interrupts during the call.
* If timers are involved, even more locking code is needed to lock out
* timer IRQ and ethernet IRQ from each other, assuming these may be nested.
*
* 2) Run lwIP in a mainloop. There is example code here: @ref lwip_nosys.
* lwIP is _ONLY_ called from mainloop callstacks here. The ethernet IRQ
* has to put received telegrams into a queue which is polled in the
* mainloop. Ensure lwIP is _NEVER_ called from an interrupt, e.g.
* some SPI IRQ wants to forward data to udp_send() or tcp_write()!
*
* OS Mode
* -------
* In OS mode, @ref callbackstyle_api AND @ref sequential_api can be used.
* @ref sequential_api are designed to be called from threads other than
* the TCPIP thread, so there is nothing to consider here.
* But @ref callbackstyle_api functions must _ONLY_ be called from
* TCPIP thread. It is a common error to call these from other threads
* or from IRQ contexts. Ethernet RX needs to deliver incoming packets
* in the correct way by sending a message to TCPIP thread, this is
* implemented in tcpip_input().
* Again, ensure lwIP is _NEVER_ called from an interrupt, e.g.
* some SPI IRQ wants to forward data to udp_send() or tcp_write()!
*
* 1) tcpip_callback() can be used get called back from TCPIP thread,
* it is safe to call any @ref callbackstyle_api from there.
*
* 2) Use @ref LWIP_TCPIP_CORE_LOCKING. All @ref callbackstyle_api
* functions can be called when lwIP core lock is aquired, see
* @ref LOCK_TCPIP_CORE() and @ref UNLOCK_TCPIP_CORE().
* These macros cannot be used in an interrupt context!
* Note the OS must correctly handle priority inversion for this.
*/

* @page bugs Reporting bugs
* Please report bugs in the lwIP bug tracker at savannah.\n

/**
* @defgroup lwip_nosys Mainloop mode ("NO_SYS")
* @ingroup lwip
* Use this mode if you do not run an OS on your system. \#define NO_SYS to 1.
* Feed incoming packets to netif->input(pbuf, netif) function from mainloop,
* *not* *from* *interrupt* *context*. You can allocate a @ref pbuf in interrupt
* context and put them into a queue which is processed from mainloop.\n
* Call sys_check_timeouts() periodically in the mainloop.\n
* Porting: implement all functions in @ref sys_time, @ref sys_prot and
* @ref compiler_abstraction.\n
* You can only use @ref callbackstyle_api in this mode.\n
* Sample code:\n
* @include NO_SYS_SampleCode.c
*/
/**
* @defgroup lwip_os OS mode (TCPIP thread)
* @ingroup lwip
* Use this mode if you run an OS on your system. It is recommended to
* use an RTOS that correctly handles priority inversion and
* to use @ref LWIP_TCPIP_CORE_LOCKING.\n
* Porting: implement all functions in @ref sys_layer.\n
* You can use @ref callbackstyle_api together with @ref tcpip_callback,
* and all @ref sequential_api.

<h1>lwIP - A Lightweight TCP/IP Stack</h1>
<p>
The web page you are watching was served by a simple web
server running on top of the lightweight TCP/IP stack <a
href="http://www.sics.se/~adam/lwip/">lwIP</a>.
</p>
<p>
lwIP is an open source implementation of the TCP/IP
protocol suite that was originally written by <a
href="http://www.sics.se/~adam/lwip/">Adam Dunkels
of the Swedish Institute of Computer Science</a> but now is
being actively developed by a team of developers
distributed world-wide. Since it's release, lwIP has
spurred a lot of interest and has been ported to several
platforms and operating systems. lwIP can be used either
with or without an underlying OS.
</p>
<p>
The focus of the lwIP TCP/IP implementation is to reduce
the RAM usage while still having a full scale TCP. This
makes lwIP suitable for use in embedded systems with tens
of kilobytes of free RAM and room for around 40 kilobytes
of code ROM.
</p>
<p>
More information about lwIP can be found at the lwIP
homepage at <a
href="http://savannah.nongnu.org/projects/lwip/">http://savannah.nongnu.org/projects/lwip/</a>
or at the lwIP wiki at <a
href="http://lwip.wikia.com/">http://lwip.wikia.com/</a>.

/**
* @defgroup httpd HTTP server
* @ingroup apps
*
* This httpd supports for a
* rudimentary server-side-include facility which will replace tags of the form
* <!--#tag--> in any file whose extension is .shtml, .shtm or .ssi with
* strings provided by an include handler whose pointer is provided to the
* module via function http_set_ssi_handler().
* Additionally, a simple common
* gateway interface (CGI) handling mechanism has been added to allow clients
* to hook functions to particular request URIs.
*
* To enable SSI support, define label LWIP_HTTPD_SSI in lwipopts.h.
* To enable CGI support, define label LWIP_HTTPD_CGI in lwipopts.h.
*
* By default, the server assumes that HTTP headers are already present in
* each file stored in the file system. By defining LWIP_HTTPD_DYNAMIC_HEADERS in
* lwipopts.h, this behavior can be changed such that the server inserts the
* headers automatically based on the extension of the file being served. If
* this mode is used, be careful to ensure that the file system image used
* does not already contain the header information.
*
* File system images without headers can be created using the makefsfile
* tool with the -h command line option.
*
*
* Notes about valid SSI tags
* --------------------------
*
* The following assumptions are made about tags used in SSI markers:
*
* 1. No tag may contain '-' or whitespace characters within the tag name.
* 2. Whitespace is allowed between the tag leadin "<!--#" and the start of
* the tag name and between the tag name and the leadout string "-->".
* 3. The maximum tag name length is LWIP_HTTPD_MAX_TAG_NAME_LEN, currently 8 characters.
*
* Notes on CGI usage
* ------------------
*
* The simple CGI support offered here works with GET method requests only
* and can handle up to 16 parameters encoded into the URI. The handler
* function may not write directly to the HTTP output but must return a
* filename that the HTTP server will send to the browser as a response to
* the incoming CGI request.
*
*
*
* The list of supported file types is quite short, so if makefsdata complains
* about an unknown extension, make sure to add it (and its doctype) to
* the 'g_psHTTPHeaders' list.
