Prusa MINI Firmware overview
|
| #define LWIP_HTTPD_CGI 0 |
Set this to 1 to support CGI (old style)
| #define LWIP_HTTPD_CGI_SSI 0 |
Set this to 1 to support CGI (new style)
| #define LWIP_HTTPD_SSI 0 |
Set this to 1 to support SSI (Server-Side-Includes)
| #define LWIP_HTTPD_SSI_RAW 0 |
Set this to 1 to implement an SSI tag handler callback that gets a const char* to the tag (instead of an index into a pre-registered array of known tags)
| #define LWIP_HTTPD_SUPPORT_POST 0 |
Set this to 1 to support HTTP POST
| #define LWIP_HTTPD_MAX_CGI_PARAMETERS 16 |
| #define LWIP_HTTPD_SSI_MULTIPART 0 |
LWIP_HTTPD_SSI_MULTIPART==1: SSI handler function is called with 2 more arguments indicating a counter for insert string that are too long to be inserted at once: the SSI handler function must then set 'next_tag_part' which will be passed back to it in the next call.
| #define LWIP_HTTPD_MAX_TAG_NAME_LEN 8 |
| #define LWIP_HTTPD_MAX_TAG_INSERT_LEN 192 |
| #define LWIP_HTTPD_POST_MANUAL_WND 0 |
| #define HTTPD_SERVER_AGENT "lwIP/" LWIP_VERSION_STRING " (http://savannah.nongnu.org/projects/lwip)" |
This string is passed in the HTTP header as "Server: "
| #define LWIP_HTTPD_DYNAMIC_HEADERS 0 |
Set this to 1 if you want to include code that creates HTTP headers at runtime. Default is off: HTTP headers are then created statically by the makefsdata tool. Static headers mean smaller code size, but the (readonly) fsdata will grow a bit as every file includes the HTTP header.
| #define HTTPD_DEBUG LWIP_DBG_OFF |
| #define HTTPD_USE_MEM_POOL 0 |
Set this to 1 to use a memp pool for allocating struct http_state instead of the heap.
| #define HTTPD_SERVER_PORT 80 |
The server port for HTTPD to use
| #define HTTPD_MAX_RETRIES 4 |
Maximum retries before the connection is aborted/closed.
| #define HTTPD_POLL_INTERVAL 4 |
The poll delay is X*500ms
| #define HTTPD_TCP_PRIO TCP_PRIO_MIN |
Priority for tcp pcbs created by HTTPD (very low by default). Lower priorities get killed first when running out of memory.
| #define LWIP_HTTPD_TIMING 0 |
Set this to 1 to enable timing each file sent
| #define HTTPD_DEBUG_TIMING LWIP_DBG_OFF |
Set this to 1 to enable timing each file sent
| #define LWIP_HTTPD_SUPPORT_EXTSTATUS 0 |
Set this to one to show error pages when parsing a request fails instead of simply closing the connection.
| #define LWIP_HTTPD_SUPPORT_V09 1 |
Set this to 0 to drop support for HTTP/0.9 clients (to save some bytes)
| #define LWIP_HTTPD_SUPPORT_11_KEEPALIVE 0 |
Set this to 1 to enable HTTP/1.1 persistent connections. ATTENTION: If the generated file system includes HTTP headers, these must include the "Connection: keep-alive" header (pass argument "-11" to makefsdata).
| #define LWIP_HTTPD_SUPPORT_REQUESTLIST 1 |
Set this to 1 to support HTTP request coming in in multiple packets/pbufs
| #define LWIP_HTTPD_REQ_QUEUELEN 5 |
Number of rx pbufs to enqueue to parse an incoming request (up to the first newline)
| #define LWIP_HTTPD_REQ_BUFSIZE LWIP_HTTPD_MAX_REQ_LENGTH |
Number of (TCP payload-) bytes (in pbufs) to enqueue to parse and incoming request (up to the first double-newline)
| #define LWIP_HTTPD_MAX_REQ_LENGTH LWIP_MIN(1023, (LWIP_HTTPD_REQ_QUEUELEN * PBUF_POOL_BUFSIZE)) |
Defines the maximum length of a HTTP request line (up to the first CRLF, copied from pbuf into this a global buffer when pbuf- or packet-queues are received - otherwise the input pbuf is used directly)
| #define LWIP_HTTPD_MAX_REQUEST_URI_LEN 63 |
This is the size of a static buffer used when URIs end with '/'. In this buffer, the directory requested is concatenated with all the configured default file names. Set to 0 to disable checking default filenames on non-root directories.
| #define LWIP_HTTPD_POST_MAX_RESPONSE_URI_LEN 63 |
Maximum length of the filename to send as response to a POST request, filled in by the application when a POST is finished.
| #define LWIP_HTTPD_SSI_INCLUDE_TAG 1 |
Set this to 0 to not send the SSI tag (default is on, so the tag will be sent in the HTML page
| #define LWIP_HTTPD_ABORT_ON_CLOSE_MEM_ERROR 0 |
Set this to 1 to call tcp_abort when tcp_close fails with memory error. This can be used to prevent consuming all memory in situations where the HTTP server has low priority compared to other communication.
| #define LWIP_HTTPD_KILL_OLD_ON_CONNECTIONS_EXCEEDED 0 |
Set this to 1 to kill the oldest connection when running out of memory for 'struct http_state' or 'struct http_ssi_state'. ATTENTION: This puts all connections on a linked list, so may be kind of slow.
| #define LWIP_HTTPD_OMIT_HEADER_FOR_EXTENSIONLESS_URI 0 |
Set this to 1 to send URIs without extension without headers
| #define HTTP_IS_TAG_VOLATILE | ( | ptr | ) | TCP_WRITE_FLAG_COPY |
Default: Tags are sent from struct http_state and are therefore volatile
| #define HTTPD_LIMIT_SENDING_TO_2MSS 1 |
| #define HTTPD_MAX_WRITE_LEN | ( | pcb | ) | (2 * tcp_mss(pcb)) |
| #define LWIP_HTTPD_CUSTOM_FILES 1 |
Set this to 1 and provide the functions:
| #define LWIP_HTTPD_DYNAMIC_FILE_READ 0 |
Set this to 1 to support fs_read() to dynamically read file data. Without this (default=off), only one-block files are supported, and the contents must be ready after fs_open().
| #define LWIP_HTTPD_FILE_STATE 0 |
Set this to 1 to include an application state argument per file that is opened. This allows to keep a state per connection/file.
| #define HTTPD_PRECALCULATED_CHECKSUM 0 |
HTTPD_PRECALCULATED_CHECKSUM==1: include precompiled checksums for predefined (MSS-sized) chunks of the files to prevent having to calculate the checksums at runtime.
| #define LWIP_HTTPD_FS_ASYNC_READ 0 |
LWIP_HTTPD_FS_ASYNC_READ==1: support asynchronous read operations (fs_read_async returns FS_READ_DELAYED and calls a callback when finished).
| #define HTTPD_USE_CUSTOM_FSDATA 0 |
Set this to 1 to include "fsdata_custom.c" instead of "fsdata.c" for the file system (to prevent changing the file included in CVS)
