When `select()` returns, Mongoose -does an IO for each socket that has data to be sent or received. Application -code must call `mg_poll_server()` in a loop. It is an error to have more then -one thread calling `mg_poll_server()`, `mg_set_option()` or any other function -that take `struct mg_server *` parameter. Mongoose does not -mutex-protect `struct mg_server *`, therefore only single thread -(Mongoose thread) should make Mongoose calls. - -`mg_poll_server()` calls user-specified event handler when certain events -occur. Sequence of events for the accepted connection is this: - - * `MG_AUTH` - Mongoose asks whether this connection is authorized. If event - handler returns `MG_FALSE`, then Mongoose does not serve the request but - sends authorization request to the client. If `MG_TRUE` is returned, - then Mongoose continues on with the request. - * `MG_REQUEST` - Mongoose asks event handler to serve the request. If - event handler serves the request by sending a reply, - it should return `MG_TRUE`. Otherwise, - it should return `MG_FALSE` which tells Mongoose that request is not - served and Mongoose should serve it. For example, event handler might - choose to serve only RESTful API requests with URIs that start with - certain prefix, and let Mongoose serve all static files. - If event handler decides to serve the request, but doesn't have - all the data at the moment, it should return `MG_MORE`. That tells - Mongoose to keep the connection open after callback returns. - - `mg_connection::connection_param` pointer is a placeholder to keep - user-specific data. For example, handler could decide to open a DB - connection and store DB connection handle in `connection_param`. - * `MG_POLL` is sent to every connection on every iteration of - `mg_poll_server()`. Event handler should return `MG_FALSE` to ignore - this event. If event handler returns `MG_TRUE`, then Mongoose assumes - that event handler has finished sending data, and Mongoose will - close the connection. - * `MG_HTTP_ERROR` sent when Mongoose is about to send HTTP error back - to the client. Event handler can choose to send a reply itself, in which - case event handler must return `MG_TRUE`. Otherwise, event handler must - return `MG_FALSE`. - * `MG_CLOSE` is sent when the connection is closed. This event is used - to cleanup per-connection state stored in `connection_param` - if it was allocated. Event handler return value is ignored. - -Sequence of events for the client connection is this: - - * `MG_CONNECT` sent when Mongoose has connected to the remote host. - This event is sent to the connection initiated by `mg_connect()` call. - Connection status is held in `mg_connection::status_code`: if zero, - then connection was successful, otherwise connection was not established. - User should send a request upon successful connection. - Event handler should return `MG_TRUE` if connection was successful and - HTTP request has been sent. Otherwise, it should send `MG_FALSE`. - * `MG_REPLY` is sent when response has been received from the remote host. - If event handler sends another request, then it should return `MG_TRUE`. - Otherwise it should return `MG_FALSE` and Mongoose will close the connection. - * `MG_CLOSE` same as for the accepted connection. - - -When mongoose buffers in HTTP request and successfully parses it, it sends -`MG_REQUEST` event for GET requests immediately. For POST requests, -Mongoose delays the call until the whole POST request is buffered in memory. -POST data is available to the callback as `struct mg_connection::content`, -and POST data length is in `struct mg_connection::content_len`. - -Note that websocket connections are treated the same way. Mongoose buffers -websocket frame in memory, and calls event handler when frame is fully -buffered. Frame data is available `struct mg_connection::content`, and -data length is in `struct mg_connection::content_len`, i.e. very similar to -the POST request. `struct mg_connection::is_websocket` flag indicates -whether the request is websocket or not. Also, for websocket requests, -there is `struct mg_connection::wsbits` field which contains first byte -of the websocket frame which URI handler can examine. Note that to -reply to the websocket client, `mg_websocket_write()` should be used. -To reply to the plain HTTP client, `mg_write_data()` should be used. - -Return value: number of active connections. - - - const char **mg_get_valid_option_names(void); - -Returns a NULL-terminated array of option names and their default values. -There are two entries per option in an array: an option name followed by a -default value.

HTTP response -consists of three parts: a status line, zero or more HTTP headers, -a response body. Mongoose provides functions for all three parts: - * `mg_send_status()` is used to create status line. This function can be - called zero or once. If `mg_send_status()` is not called, then Mongoose - will send status 200 (success) implicitly. - * `mg_send_header()` adds HTTP header to the response. This function could - be called zero or more times. - * `mg_send_data()` and `mg_printf_data()` are used to send data to the - client. Note that Mongoose adds `Transfer-Encoding: chunked` header - implicitly, and sends data in chunks. Therefore, it is not necessary to - set `Content-Length` header. Note that `mg_send_data()` and - `mg_printf_data()` do not send data immediately. Instead, they spool - data in memory, and Mongoose sends that data later after URI handler - returns. If data to be sent is huge, an URI handler might - send data in pieces by saving state in - `struct mg_connection::connection_param` variable and returning `0`.

Mongoose can call user-defined -function when certain events occur. -That function is called _an event handler_, and it is the second parameter -to `mg_create_server()` function. Here is the example event handler function: - - int event_handler(struct mg_connection *conn, enum mg_event ev) { - switch (ev) { - case MG_AUTH: return MG_TRUE; - default: return MG_FALSE; - } - } - -Event handler is called by Mongoose with `struct mg_connection *` -pointer and an event number. `struct mg_connection *conn` -has all information about the request: HTTP headers, POST or websocket -data buffer, etcetera. `enum mg_event ev` tells which exactly event is sent. -For each event, an event handler returns a value which tells Mongoose how -to behave. - -The sequence of events for every connection is this: - - * `MG_AUTH` - Mongoose asks whether this connection is authorized. If event - handler returns `MG_FALSE`, then Mongoose does not serve the request but - sends authorization request to the client. If `MG_TRUE` is returned, - then Mongoose continues on with the request. - * `MG_REQUEST` - Mongoose asks event handler to serve the request. If - event handler serves the request by sending a reply, - it should return `MG_TRUE`. Otherwise, - it should return `MG_FALSE` which tells Mongoose that request is not - served and Mongoose should serve it. For example, event handler might - choose to serve only RESTful API requests with URIs that start with - certain prefix, and let Mongoose serve all static files. - If event handler decides to serve the request, but doesn't have - all the data at the moment, it should return `MG_MORE`. That tells - Mongoose to keep the connection open after callback returns. - - `mg_connection::connection_param` pointer is a placeholder to keep - user-specific data. For example, handler could decide to open a DB - connection and store DB connection handle in `connection_param`. - * `MG_POLL` is sent to every connection on every iteration of - `mg_poll_server()`. Event handler should return `MG_FALSE` to ignore - this event. If event handler returns `MG_TRUE`, then Mongoose assumes - that event handler has finished sending data, and Mongoose will - close the connection. - * `MG_HTTP_ERROR` sent when Mongoose is about to send HTTP error back - to the client. Event handler can choose to send a reply itself, in which - case event handler must return `MG_TRUE`.

If third -party observes all messages passed by, it would be very -hard for the third party (though not impossible) to decrypt the communication. - -The idea is based on so-called public key encryption. Communicating parties -have two keys: a public key and a private key. A public key is advertised -to everybody, and it is contained in a certificate. A private key is kept -secret. Security algorithm works in a way that anybody can encrypt -a message using public key, and only private key can decrypt it. - -This is why web server needs both private key and certificate: private key -is used to decrypt incoming messages, and certificate is used to tell the -public key to the other party. When communication starts, parties exchange -their public keys, and keep private keys to themselves. Man-in-the-middle -who observes the communication is unable to decrypt the messages cause -private keys are required for decryption. - -Encryption algorithms are built on top of hard mathematical problem, which -makes it very expensive for man-in-the-middle to compute private keys. -For example, RSA algorithm is based on a mathematical problem of factorization. -It is easy to generate two very large prime numbers `P` and `Q` and make -a product `P * Q`. But given a product, it is very hard to recover these -two prime numbers - this is called factorization. diff --git a/3rdparty/mongoose/docs/Usage.md b/3rdparty/mongoose/docs/Usage.md deleted file mode 100644 index b9f7052fa09..00000000000 --- a/3rdparty/mongoose/docs/Usage.md +++ /dev/null @@ -1,86 +0,0 @@ -# Mongoose User Guide - -Mongoose is small and easy to use web server built on top of -mongoose library.
