Fixed some sign comparison warnings.
Added utility functions to fr::Packet's for:
Getting read cursor position.
Relative read cursor seeking.
Asserting that data remains in the packet
Getting the amount of data remaining
Getting the size of the packet
Recv timeouts can now be specified for sockets, which is the maximum amount of time to wait before returning during a receive. They will return WouldBlock if no data was received during the wait time.
Receiving a HTTP request in non-blocking mode will no longer fail.
Added missing move/copy constructor deletors to SSLSocket, to prevent the object from becoming invalid.
Removed noexcept specifier from some constructors where valid exceptions can be thrown.
Exceptions are now thrown from the SSLSocket constructor if it fails to initialise properly, rather than printing something out to stderr and continuing.
Replaced instances of resize&memcpy with append, which gives a noticeable performance boost.
fr::Packet::operator<<(const char *str) no longer converts str into an std::string before adding it, removing an unneeded copy.
fr::Packet::clear no longer calls erase, should result in more of the internal buffer remaining allocated.
Framing for std::vector's has been changed from a uint64_t to a uint32_t (breaking change for packet framing!)
Previously, fr::Packet would use 'size_t' for dealing with vector sizes. This is not ideal though, as the size of size_t is platform depenant, meaning that fr::Packet's sent on one computer might be incompatible with other systems.
Added Sha1 hash, and Base64 encode implementations which are optionally compiled if websock support is enabled, to assist in the WebSock handshake.
Added WebSocket to manage the WebSock protocol during connections.
Added WebFrame to allow for sending/receiving data through the WebSock protocol easily.
Fixed TcpSocket::set_descriptor(nullptr) causing an invalid read from address 0x0.
Improved HTTP response/request parsing so that they report a parse failure if the first few bytes of the HTTP request don't match the expected format rather than continuing to look for an end of header.
Fixed broken fr::Http::url_encode() implementation.
Optimised fr::Http::url_decode() implementation.
Added fr::Http unit tests.
Fixed SSLListener failing to accept SSLSockets properly (not setting the descriptor properly).
TcpSocket::receive_raw and SSLSocket::receive_raw now behave the same, rather than SSLSocket acting more like Socket::receive_all.
Documented specific return values from Socket::receive_all().
Socket::receive_all now returns WouldBlock if the socket is in blocking mode and the first read returns no data, so it doesn't behave like a blocking socket.
Disabled copying/moving of sockets. Copying shouldn't have been enabled, but might add move constructors in the future.
Added Socket::disconnect, which internally just calls close_socket, to allow for protocol-specific disconnect sequences in the future (WebSockets).
Socket mutexes are no longer really required, and so have been removed.
Added more tests for network encoding functions, and the URL parser.
The URL parser now returns a path preceeded with a '/' instead of cutting it out. Added get_uri() to URL, for getting the whole URI, so users don't have to concat it themselves from the more specialised functions.
Fixed default socket connect timeout checking for the wrong value.
Fixed request_type_strings not containing all of the possible request types.
Fixed README using old socket close syntax.
Cleaned up the examples a bit.
Both fr::TcpSocket and fr::SSLSocket can have timeouts specified when connecting. This works by putting the socket into non-blocking mode, making a connect, and then selecting on the socket for the requested timeout. If the select times out then we've failed to connect, if it didn't time out then we've connected.
Receiving an http request/response will now return errors like HttpHeaderTooBig, instead of the type being set to that.
Added fr::Socket::status_to_string for converting status values into English strings.
Added the ability to disable certificate verification for SSL sockets which is useful for testing.
Added the ability to specify maximum HTTP request header/body sizes in the CMake build config to prevent a malicious client from causing OOM errors.
Fixed a bug in HttpResponse and HttpRequest parse causing it to abort if the request is invalid in some cases.
Started work on tests for fr::HttpRequest.
Fixed the final POST data variable containing header data it shouldn't (\r\n\r\n).
Fixed fr::Http::header_exists, and family, not converting things to lowercase first.
fr::HttpSocket has been removed.
fr::Sendable has been added. Classes can inherit this if they want to be sendable through sockets. Both fr::Http (which is inherited by fr::HttpRequest and fr::HttpResponse), and fr::Packet inherit this, to allow them to be sent through fr::Socket::send()/fr::Socket::receive().
Fixed broken fr::SocketSelector and fr::SocketReactor, as they no longer accepted fr::Listener's due to fr::Listener no longer inheriting fr::Socket.
Fixed Content-Length header being added to Http responses even if there's a pre-existing one.
Fixed header parsing sometimes adding a carriage return to the header value.
Removed useless copy/move constructors from HttpResponse, causing issues.
fr::TcpSocket checked if the recv response was greater than 0, which created issues as 0 is a valid result if no data was received and no error occurred.
fr::HttpResponse::construct() now adds in a content-length header.
fr::HttpResponse::parse trims the body if it's larger than content length.
fr::Http::set_uri() now prepends a '/' if one's not provided.
Fixed fr::Http::parse_header from cutting off the end of headers.
