-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_parser` 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_parser` 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                         |

-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.
-
-See examples of reading in headers:

-* [partial example](http://gist.github.com/155877) in C
-* [from http-parser tests](http://github.com/joyent/http-parser/blob/37a0ff8/test.c#L403) in C

+# llhttp
+[![CI](https://github.com/nodejs/llhttp/workflows/CI/badge.svg)](https://github.com/nodejs/llhttp/actions?query=workflow%3ACI)
+
+Port of [http_parser][0] to [llparse][1].
+
+## Why?
+
+Let's face it, [http_parser][0] is practically unmaintainable. Even
+introduction of a single new method results in a significant code churn.
+
+This project aims to:
+
+* Make it maintainable
+* Verifiable
+* Improving benchmarks where possible
+
+More details in [Fedor Indutny's talk at JSConf EU 2019](https://youtu.be/x3k_5Mi66sY)
+
+## How?
+
+Over time, different approaches for improving [http_parser][0]'s code base
+were tried. However, all of them failed due to resulting significant performance
+degradation.
+
+This project is a port of [http_parser][0] to TypeScript. [llparse][1] is used
+to generate the output C source file, which could be compiled and
+linked with the embedder's program (like [Node.js][7]).
+
+## Performance
+
+So far llhttp outperforms http_parser:
+
+|                 | input size |  bandwidth   |  reqs/sec  |   time  |
+|:----------------|-----------:|-------------:|-----------:|--------:|
+| **llhttp**      | 8192.00 mb | 1777.24 mb/s | 3583799.39 req/sec | 4.61 s |
+| **http_parser** | 8192.00 mb | 694.66 mb/s | 1406180.33 req/sec | 11.79 s |
+
+llhttp is faster by approximately **156%**.
+
+## Maintenance
+
+llhttp project has about 1400 lines of TypeScript code describing the parser
+itself and around 450 lines of C code and headers providing the helper methods.
+The whole [http_parser][0] is implemented in approximately 2500 lines of C, and
+436 lines of headers.
+
+All optimizations and multi-character matching in llhttp are generated
+automatically, and thus doesn't add any extra maintenance cost. On the contrary,
+most of http_parser's code is hand-optimized and unrolled. Instead describing
+"how" it should parse the HTTP requests/responses, a maintainer should
+implement the new features in [http_parser][0] cautiously, considering
+possible performance degradation and manually optimizing the new code.
+
+## Verification
+
+The state machine graph is encoded explicitly in llhttp. The [llparse][1]
+automatically checks the graph for absence of loops and correct reporting of the
+input ranges (spans) like header names and values. In the future, additional
+checks could be performed to get even stricter verification of the llhttp.
+
+## Usage
+
+```C
+#include "llhttp.h"
+
+llhttp_t parser;
+llhttp_settings_t settings;
+
+/* Initialize user callbacks and settings */
+llhttp_settings_init(&settings);
+
+/* Set user callback */
+settings.on_message_complete = handle_on_message_complete;
+
+/* Initialize the parser in HTTP_BOTH mode, meaning that it will select between
+ * HTTP_REQUEST and HTTP_RESPONSE parsing automatically while reading the first
+ * input.
+ */
+llhttp_init(&parser, HTTP_BOTH, &settings);
+
+/* Parse request! */
+const char* request = "GET / HTTP/1.1\r\n\r\n";
+int request_len = strlen(request);
+
+enum llhttp_errno err = llhttp_execute(&parser, request, request_len);
+if (err == HPE_OK) {
+  /* Successfully parsed! */
+} else {
+  fprintf(stderr, "Parse error: %s %s\n", llhttp_errno_name(err),
+          parser.reason);
+}
+```
