 ## About
-
-Fork of [KeePassX](https://www.keepassx.org/) that [aims to incorporate stalled Pull Requests, features, and bug fixes that are not being incorporated into the main KeePassX baseline](https://github.com/keepassxreboot/keepassx/issues/43).
+KeePassXC is a fork of [KeePassX](https://www.keepassx.org/) that [aims to incorporate stalled pull requests, features, and bug fixes that have never made it into the main KeePassX repository](https://github.com/keepassxreboot/keepassx/issues/43).
 
 
-#### Additional Reboot Features
- - keepasshttp support for use with [PassIFox](https://addons.mozilla.org/en-us/firefox/addon/passifox/) for Mozilla Firefox and [chromeIPass](https://chrome.google.com/webstore/detail/chromeipass/ompiailgknfdndiefoaoiligalphfdae) for Google Chrome.
+## Additional features compared to KeePassX
+- Autotype on all three major platforms (Linux, Windows, OS X)
+- Stand-alone password generator
+- Password strength meter
+- Use website's favicons as entry icons
+- Merging of databases
+- Automatic reload when the database changed on disk
+- KeePassHTTP support for use with [PassIFox](https://addons.mozilla.org/en-us/firefox/addon/passifox/) in Mozilla Firefox and [chromeIPass](https://chrome.google.com/webstore/detail/chromeipass/ompiailgknfdndiefoaoiligalphfdae) in Google Chrome or Chromium.
 
-KeePassHttp implementation has been forked from jdachtera's repository, which in turn was based on code from code with Francois Ferrand's [keepassx-http](https://gitorious.org/keepassx/keepassx-http/source/master) repository.
-
-This is a rebuild from [denk-mal's keepasshttp](https://github.com/denk-mal/keepassx.git) that brings it forward to Qt5 and KeePassX v2.x.
+For a full list of features and changes, read the [CHANGELOG](CHANGELOG) document.
 
+### Note about KeePassHTTP
+KeePassHTTP is not a highly secure protocol and has certain flaw which allow an attacker to decrypt your passwords when they manage to intercept communication between a KeePassHTTP server and PassIFox/chromeIPass over a network connection (see [here](https://github.com/pfn/keepasshttp/issues/258) and [here](https://github.com/keepassxreboot/keepassxc/issues/147)). KeePassXC therefore strictly limits communication between itself and the browser plugin to your local computer. As long as your computer is not compromised, your passwords are fairly safe that way, but still use it at your own risk!
 
 ### Installation
+Pre-compiled binaries can be found on the [downloads page](https://keepassxc.org/download).  Additionally, individual Linux distributions may ship their own versions, so please check out your distribution's package list to see if KeePassXC is available.
 
-Right now KeePassXC does not have a precompiled executable or an installation package.<br/>
-So you must install it from its source code.
+### Building KeePassXC yourself
 
-**More detailed instructions are available in the INSTALL file or at the [Wiki page](https://github.com/keepassxreboot/keepassx/wiki/Install-Instruction-from-Source).**
+*More detailed instructions are available in the INSTALL file or on the [Wiki page](https://github.com/keepassxreboot/keepassx/wiki/Install-Instruction-from-Source).*
 
-First you must download the KeePassXC source code as ZIP file or with Git.
+First, you must download the KeePassXC [source tarball](https://keepassxc.org/download#source) or check out the latest version from our [Git repository](https://github.com/keepassxreboot/keepassxc).
 
-Generally you can build and install KeePassXC with the following commands from a Terminal in the KeePassXC folder
-```
-mkdir build
-cd build
-cmake -DWITH_TESTS=OFF ..
-make
-sudo make install
-```
-
-
-### Clone Repository
-
-Clone the repository to a suitable location where you can extend and build this project.
+To clone the project from Git, `cd` to a suitable location and run
 
 ```bash
 git clone https://github.com/keepassxreboot/keepassxc.git
 ```
 
-**Note:** This will clone the entire contents of the repository at the HEAD revision.
+This will clone the entire contents of the repository and check out the current `develop` branch.
 
-To update the project from within the project's folder you can run the following command:
+To update the project from within the project's folder, you can run the following command:
 
 ```bash
 git pull
 ```
 
+Once you have downloaded the source code, you can `cd` into the source code directory and build and install KeePassXC with
+
+```
+mkdir build
+cd build
+cmake -DWITH_TESTS=OFF ..
+make -j8
+sudo make install
+```
+
+To enable autotype, add `-DWITH_XC_AUTOTYPE=ON` to the `cmake` command. KeePassHTTP support is compiled in by adding `-DWITH_XC_HTTP=ON`. If these options are not specified, KeePassXC will be built without these plugins.

+## About
+[TOC](#table-of-contents)
+
+`QHttp` is a lightweight, asynchronous and fast HTTP library, containing both server and client side classes for managing connections, parsing and building HTTP requests and responses. this project is inspired by [nikhilm/qhttpserver](https://github.com/nikhilm/qhttpserver) effort to implement a Qt HTTP server. `QHttp` pushes the idea further by implementing client classes and better memory management, a lot more Node.js-like API, ...
+
+* the fantastic [nodejs/http-parser](https://github.com/nodejs/http-parser) is the core parser of HTTP requests (server mode) and responses (client mode).
+
+* By using `std::function` and `c++11 lambda`, the API is intentionally similar to the [Node.js' http module](http://nodejs.org/api/http.html). Asynchronous and non-blocking HTTP programming is quite easy with `QHttp`. have a look at [sample codes](#sample-codes).
+
+* the objective of `QHttp` is being light weight with a simple API for Qt developers to implement RESTful web services in private (internal) zones. [more](#disclaimer)
+
+
+
+## Sample codes
+[TOC](#table-of-contents)
+
+a HelloWorld **HTTP server** by `QHttp` looks like:
+``` cpp
+int main(int argc, char** argv) {
+    QCoreApplication app(argc, argv);
+
+    using namespace qhttp::server;
+    QHttpServer server(&app);
+    // listening on 0.0.0.0:8080
+    server.listen(QHostAddress::Any, 8080, [](QHttpRequest* req, QHttpResponse* res) {
+
+        res->setStatusCode(qhttp::ESTATUS_OK);      // http status 200
+        //res->addHeader("connection", "close");    // optional, it's the default header
+        res->end("Hello World!\n");                 // the response body data
+        // by "connection: close", the req and res objects will be deleted automatically.
+    });
+
+    if ( !server.isListening() ) {
+        fprintf(stderr, "failed. can not listen at port 8080!\n");
+        return -1;
+    }
+
+    return app.exec();
+}
+```
+
+to request weather information by **HTTP client**:
+```cpp
+int main(int argc, char** argv) {
+    QCoreApplication app(argc, argv);
+
+    using namespace qhttp::client;
+    QHttpClient  client(&app);
+    QByteArray   httpBody;
+
+    QUrl weatherUrl("http://api.openweathermap.org/data/2.5/weather?q=tehran,ir&units=metric&mode=xml");
+
+    client.request(qhttp::EHTTP_GET, weatherUrl, [&httpBody](QHttpResponse* res) {
+        // response handler, called when the HTTP headers of the response are ready
+
+        // gather HTTP response data
+        res->onData([&httpBody](const QByteArray& chunk) {
+            httpBody.append(chunk);
+        });
+
+        // called when all data in HTTP response have been read.
+        res->onEnd([&httpBody]() {
+            // print the XML body of the response
+            puts("\n[incoming response:]");
+            puts(httpBody.constData());
+            puts("\n\n");
+
+            QCoreApplication::instance()->quit();
+        });
+
+        // just for fun! print incoming headers:
+        puts("\n[Headers:]");
+        const qhttp::THeaderHash& hs = res->headers();
+        for ( auto cit = hs.constBegin(); cit != hs.constEnd(); cit++) {
+            printf("%s : %s\n", cit.key().constData(), cit.value().constData());
+        }
+    });
+
+    // set a timeout for making the request
+    client.setConnectingTimeOut(10000, []{
+        qDebug("connecting to HTTP server timed out!");
+        QCoreApplication::quit();
+    });
+
+
+    return app.exec();
+}
+```
+
+
+## Features
+[TOC](#table-of-contents)
+
+* the only dependencies are: [Qt 5](http://qt-project.org/downloads), [c++11](http://en.wikipedia.org/wiki/C%2B%2B11) and [joyent/http-parser](https://github.com/joyent/http-parser)
+
+* both TCP and UNIX (local) sockets are supported as backend.
+
+* separate `namespace`s for server and client classes.
+
+* HTTP server classes: [QHttpServer](./src/qhttpserver.hpp), [QHttpConnection](./src/qhttpserverconnection.hpp), [QHttpRequest](./src/qhttpserverrequest.hpp) and [QHttpResponse](./src/qhttpserverresponse.hpp).
+
+* HTTP client classes: [QHttpClient](./src/qhttpclient.hpp), [QHttpRequest](./src/qhttpclientrequest.hpp) and [QHttpResponse](./src/qhttpclientresponse.hpp).
+
+* **automatic memory management** of objects. Instances of connections, requests and replies will be deleted automatically when socket drops or disconnected.
+
+* **PIMPL** (Private classes) to achieve better ABI compatibility and cleaner API.
+
+* **Asynchronous** and **non-blocking**. You can handle thousands of concurrent HTTP connections efficiently by a single thread, although a multi-threaded HTTP server is easy to implement.
+
+* **high throughput**, I have tried the `QHttp` and [gason++](https://github.com/azadkuh/gason--) to implement a REST/Json web service on an Ubuntu VPS (dual core + 512MB ram) with more than **5800** connections per second (stress test). On a MacBook Pro (i5 4258U 4cores with HT + 8096MB ram), `QHttp` easily reaches to more than **11700** connections / second. Generally `QHttp` is **1.5x ~ 3x** faster than `Node.js` depending on your machine / OS. check [benchmark app](./example/benchmard/README.md) to measure your system.
+
+* Tested under **Linux** (Ubuntu 12.04 LTS, 14.04 LTS, g++) and **OS X** (10.9/10.10/10.11, clang). Easily portable where ever Qt 5 works. (tested by some users on Windows7/msvc2013 and Windows8.1/msvc2015)
+
+
+## Setup
+[TOC](#table-of-contents)
+
+instructions:
+```bash
+# first clone this repository:
+$> git clone --depth=1 https://github.com/azadkuh/qhttp.git -b master
+$> cd qhttp
+
+# prepare dependencies:
+$> ./update-dependencies.sh
+
+# now build the library and the examples
+$> qmake qhttp.pro
+$> make -j 8
+```
+
+## Multi-threading
+[TOC](#table-of-contents)
+
+As `QHttp` is **asynchronous** and **non-blocking**, your app can handle thousands of concurrent HTTP connections by a single thread.
+
+in some rare scenarios you may want to use multiple handler threads (although it's not the best solution):
+
+* there are some blocking APIs (QSql, system calls, ...) in your connection handler (adopting asynchronous layer over the blocking API is a better approach).
+
+* the hardware has lots of free cores and the measurement shows that the load on the main `QHttp` thread is close to highest limit. There you can spawn some other handler threads.
+
+
+[benchmark example](./example/benchmark/README.md) shows how to implement a single or multi threaded HTTP app (both server and client). This example uses worker `QThread` and `QObject::moveToThread()` for worker objects. see also: [Subclassing no longer recommended way of using QThread](http://qt-project.org/doc/note_revisions/5/8/view).
+
+**Note**:
+> moving objects between threads is an expensive job, more ever the locking/unlocking mechanism, creating or stopping threads, ... cost even more! so using multiple threads in an application is not guaranteed to get better performance, but it's guaranteed to add more complexity, nasty bugs and headache!
+
+see why other top performer networking libraries as ZeroMQ are concurrent but not multi-threaded by default:
+
+* [ZeroMQ : Multithreading Magic](http://zeromq.org/blog:multithreading-magic)
+* [Node.js : about](http://nodejs.org/about/)

+
+
+## Disclaimer
+[TOC](#table-of-contents)
+
+* Implementing a lightweight and simple HTTP server/client in Qt with Node.js like API, is the main purpose of `QHttp`.
+
+* There are lots of features in a full blown HTTP server which are out of scope of this small library, although those can be added on top of `QHttp`.
+
+* The client classes are by no mean designed as a `QNetworkAccessManager` replacement. `QHttpClient` is simpler and lighter, for serious scenarios just use `QNetworkAccessManager`.
+
+* I'm a busy person.
+
+
+> If you have any ideas, critiques, suggestions or whatever you want to call it, please open an issue. I'll be happy to hear from you what you'd see in this lib. I think about all suggestions, and I try to add those that make sense.

+HTTP Parser
+===========
+
+[![Build Status](https://api.travis-ci.org/nodejs/http-parser.svg?branch=master)](https://travis-ci.org/nodejs/http-parser)
+
+This is a parser for HTTP messages written in C. It parses both requests and
+responses. The parser is designed to be used in performance HTTP
+applications. It does not make any syscalls nor allocations, it does not
+buffer data, it can be interrupted at anytime. Depending on your
+architecture, it only requires about 40 bytes of data per message
+stream (in a web server that is per connection).
+
+Features:
+
+  * No dependencies
+  * Handles persistent streams (keep-alive).
+  * Decodes chunked encoding.
+  * Upgrade support
+  * Defends against buffer overflow attacks.
+
+The parser extracts the following information from HTTP messages:
+
+  * Header fields and values
+  * Content-Length
+  * Request method
+  * Response status code
+  * Transfer-Encoding
+  * HTTP version
+  * Request URL
+  * Message body
+
+
+Usage
+-----
+
+One `http_parser` object is used per TCP connection. Initialize the struct
+using `http_parser_init()` and set the callbacks. That might look something
+like this for a request parser:
+```c
+http_parser_settings settings;
+settings.on_url = my_url_callback;
+settings.on_header_field = my_header_field_callback;
+/* ... */
+
+http_parser *parser = malloc(sizeof(http_parser));
+http_parser_init(parser, HTTP_REQUEST);
+parser->data = my_socket;
+```
+
+When data is received on the socket execute the parser and check for errors.
+
+```c
+size_t len = 80*1024, nparsed;
+char buf[len];
+ssize_t recved;
+
+recved = recv(fd, buf, len, 0);
+
+if (recved < 0) {
+  /* Handle error. */
+}
+
+/* Start up / continue the parser.
+ * Note we pass recved==0 to signal that EOF has been received.
+ */
+nparsed = http_parser_execute(parser, &settings, buf, recved);
+
+if (parser->upgrade) {
+  /* handle new protocol */
+} else if (nparsed != recved) {
+  /* Handle error. Usually just close the connection. */
+}
+```
+
+HTTP needs to know where the end of the stream is. For example, sometimes
+servers send responses without Content-Length and expect the client to
+consume input (for the body) until EOF. To tell http_parser about EOF, give
+`0` as the fourth parameter to `http_parser_execute()`. Callbacks and errors
+can still be encountered during an EOF, so one must still be prepared
+to receive them.
+
+Scalar valued message information such as `status_code`, `method`, and the
+HTTP version are stored in the parser structure. This data is only
+temporally stored in `http_parser` and gets reset on each new message. If
+this information is needed later, copy it out of the structure during the
+`headers_complete` callback.
+
+The parser decodes the transfer-encoding for both requests and responses
+transparently. That is, a chunked encoding is decoded before being sent to
+the on_body callback.
+
+
+The Special Problem of Upgrade
+------------------------------
+
+HTTP supports upgrading the connection to a different protocol. An
+increasingly common example of this is the WebSocket protocol which sends
+a request like
+
+        GET /demo HTTP/1.1
+        Upgrade: WebSocket
+        Connection: Upgrade
+        Host: example.com
+        Origin: http://example.com
+        WebSocket-Protocol: sample
+
+followed by non-HTTP data.
+
+(See [RFC6455](https://tools.ietf.org/html/rfc6455) for more information the
+WebSocket protocol.)
+
+To support this, the parser will treat this as a normal HTTP message without a
+body, issuing both on_headers_complete and on_message_complete callbacks. However
+http_parser_execute() will stop parsing at the end of the headers and return.
+
+The user is expected to check if `parser->upgrade` has been set to 1 after
+`http_parser_execute()` returns. Non-HTTP data begins at the buffer supplied
+offset by the return value of `http_parser_execute()`.
+
+
+Callbacks
+---------
+
+During the `http_parser_execute()` call, the callbacks set in
+`http_parser_settings` will be executed. The parser maintains state and
+never looks behind, so buffering the data is not necessary. If you need to
+save certain data for later usage, you can do that from the callbacks.
+
+There are two types of callbacks:
+
+* notification `typedef int (*http_cb) (http_parser*);`
+    Callbacks: on_message_begin, on_headers_complete, on_message_complete.
+* data `typedef int (*http_data_cb) (http_parser*, const char *at, size_t length);`
+    Callbacks: (requests only) on_url,
+               (common) on_header_field, on_header_value, on_body;
+
+Callbacks must return 0 on success. Returning a non-zero value indicates
+error to the parser, making it exit immediately.
+
+For cases where it is necessary to pass local information to/from a callback,
+the `http_parser` object's `data` field can be used.
+An example of such a case is when using threads to handle a socket connection,
+parse a request, and then give a response over that socket. By instantiation
+of a thread-local struct containing relevant data (e.g. accepted socket,
+allocated memory for callbacks to write into, etc), a parser's callbacks are
+able to communicate data between the scope of the thread and the scope of the
+callback in a threadsafe manner. This allows http-parser to be used in
+multi-threaded contexts.
+
+Example:
+```c
+ typedef struct {
+  socket_t sock;
+  void* buffer;
+  int buf_len;
+ } custom_data_t;
+
+
+int my_url_callback(http_parser* parser, const char *at, size_t length) {
+  /* access to thread local custom_data_t struct.
+  Use this access save parsed data for later use into thread local
+  buffer, or communicate over socket
+  */
+  parser->data;
+  ...
+  return 0;
+}
+
+...
+
+void http_parser_thread(socket_t sock) {
+ int nparsed = 0;
+ /* allocate memory for user data */
+ custom_data_t *my_data = malloc(sizeof(custom_data_t));
+
+ /* some information for use by callbacks.
+ * achieves thread -> callback information flow */
+ my_data->sock = sock;
+
+ /* instantiate a thread-local parser */
+ http_parser *parser = malloc(sizeof(http_parser));
+ http_parser_init(parser, HTTP_REQUEST); /* initialise parser */
+ /* this custom data reference is accessible through the reference to the
+ parser supplied to callback functions */
+ parser->data = my_data;
+
+ http_parser_settings settings; /* set up callbacks */
+ settings.on_url = my_url_callback;
+
+ /* execute parser */
+ nparsed = http_parser_execute(parser, &settings, buf, recved);
+
+ ...
+ /* parsed information copied from callback.
+ can now perform action on data copied into thread-local memory from callbacks.
+ achieves callback -> thread information flow */
+ my_data->buffer;
+ ...
+}
+
+```
+
+In case you parse HTTP message in chunks (i.e. `read()` request line
+from socket, parse, read half headers, parse, etc) your data callbacks
+may be called more than once. Http-parser guarantees that data pointer is only
+valid for the lifetime of callback. You can also `read()` into a heap allocated
+buffer to avoid copying memory around if this fits your application.
+
+Reading headers may be a tricky task if you read/parse headers partially.
+Basically, you need to remember whether last header callback was field or value
+and apply the following logic:
+
+    (on_header_field and on_header_value shortened to on_h_*)
+     ------------------------ ------------ --------------------------------------------
+    | State (prev. callback) | Callback   | Description/action                         |
+     ------------------------ ------------ --------------------------------------------
+    | nothing (first call)   | on_h_field | Allocate new buffer and copy callback data |
+    |                        |            | into it                                    |
+     ------------------------ ------------ --------------------------------------------
+    | value                  | on_h_field | New header started.                        |
+    |                        |            | Copy current name,value buffers to headers |
+    |                        |            | list and allocate new buffer for new name  |
+     ------------------------ ------------ --------------------------------------------
+    | field                  | on_h_field | Previous name continues. Reallocate name   |
+    |                        |            | buffer and append callback data to it      |
+     ------------------------ ------------ --------------------------------------------
+    | field                  | on_h_value | Value for current header started. Allocate |
+    |                        |            | new buffer and copy callback data to it    |
+     ------------------------ ------------ --------------------------------------------
+    | value                  | on_h_value | Value continues. Reallocate value buffer   |
+    |                        |            | and append callback data to it             |
+     ------------------------ ------------ --------------------------------------------
+
+
+Parsing URLs
+------------
+
+A simplistic zero-copy URL parser is provided as `http_parser_parse_url()`.
+Users of this library may wish to use it to parse URLs constructed from
+consecutive `on_url` callbacks.
