4 v1.5-chrome47-firefox41
5 =======================
10 LWS_CALLBACK_CLIENT_CONNECTION_ERROR may provide an error string if in is
11 non-NULL. If so, the string has length len.
13 LWS_SERVER_OPTION_PEER_CERT_NOT_REQUIRED is available to relax the requirement
14 for peer certs if you are using the option to require client certs.
16 LWS_WITHOUT_BUILTIN_SHA1 cmake option forces lws to use SHA1() defined
17 externally, eg, byOpenSSL, and disables build of libwebsockets_SHA1()
20 v1.4-chrome43-firefox36
21 =======================
26 There's a new member in the info struct used to control context creation,
27 ssl_private_key_password, which allows passing into lws the passphrase on
30 There's a new member in struct protocols, id, which is ignored by lws but can
31 be used by the user code to mark the selected protocol by user-defined version
32 or capabliity flag information, for the case multiple versions of a protocol are
35 int lws_is_ssl(wsi) added to allow user code to know if the connection was made
36 over ssl or not. If LWS_SERVER_OPTION_ALLOW_NON_SSL_ON_SSL_PORT is used, both
37 ssl and non-ssl connections are possible and may need to be treated differently
40 int lws_partial_buffered(wsi) added... should be checked after any
41 libwebsocket_write that will be followed by another libwebsocket_write inside
42 the same writeable callback. If set, you can't do any more writes until the
43 writeable callback is called again. If you only do one write per writeable callback,
46 HTTP2-related: HTTP2 changes how headers are handled, lws now has new version-
47 agnositic header creation APIs. These do the right thing depending on each
48 connection's HTTP version without the user code having to know or care, except
49 to make sure to use the new APIs for headers (test-server is updated to use
50 them already, so look there for examples)
52 The APIs "render" the headers into a user-provided buffer and bump *p as it
53 is used. If *p reaches end, then the APIs return nonzero for error.
55 LWS_VISIBLE LWS_EXTERN int
56 lws_add_http_header_status(struct libwebsocket_context *context,
57 struct libwebsocket *wsi,
62 Start a response header reporting status like 200, 500, etc
64 LWS_VISIBLE LWS_EXTERN int
65 lws_add_http_header_by_name(struct libwebsocket_context *context,
66 struct libwebsocket *wsi,
67 const unsigned char *name,
68 const unsigned char *value,
73 Add a header like name: value in HTTP1.x
75 LWS_VISIBLE LWS_EXTERN int
76 lws_finalize_http_header(struct libwebsocket_context *context,
77 struct libwebsocket *wsi,
81 Finish off the headers, like add the extra \r\n in HTTP1.x
83 LWS_VISIBLE LWS_EXTERN int
84 lws_add_http_header_by_token(struct libwebsocket_context *context,
85 struct libwebsocket *wsi,
86 enum lws_token_indexes token,
87 const unsigned char *value,
92 Add a header by using a lws token as the name part. In HTTP2, this can be
93 compressed to one or two bytes.
99 protocols struct member no_buffer_all_partial_tx is removed. Under some
100 conditions like rewriting extension such as compression in use, the built-in
101 partial send buffering is the only way to deal with the problem, so turning
102 it off is deprecated.
108 HTTP2-related: API libwebsockets_serve_http_file() takes an extra parameter at
111 int other_headers_len)
113 If you are providing other headers, they must be generated using the new
114 HTTP-version-agnostic APIs, and you must provide the length of them using this
115 additional parameter.
117 struct lws_context_creation_info now has an additional member
118 SSL_CTX *provided_client_ssl_ctx you may set to an externally-initialized
119 SSL_CTX managed outside lws. Defaulting to zero keeps the existing behaviour of
120 lws managing the context, if you memset the struct to 0 or have as a filescope
121 initialized struct in bss, no need to change anything.

188 POST method is supported
190 The protocol 0 / HTTP callback can now get two new kinds of callback,
191 LWS_CALLBACK_HTTP_BODY (in and len are a chunk of the body of the HTTP request)
192 and LWS_CALLBACK_HTTP_BODY_COMPLETION (the expected amount of body has arrived
193 and been passed to the user code already). These callbacks are used with the
194 post method (see the test server for details).
196 The period between the HTTP header completion and the completion of the body
197 processing is protected by a 5s timeout.
199 The chunks are stored in a malloc'd buffer of size protocols[0].rx_buffer_size.
202 New server option you can enable from user code
203 LWS_SERVER_OPTION_ALLOW_NON_SSL_ON_SSL_PORT allows non-SSL connections to
204 also be accepted on an SSL listening port. It's disabled unless you enable
208 Two new callbacks are added in protocols[0] that are optional for allowing
209 limited thread access to libwebsockets, LWS_CALLBACK_LOCK_POLL and
210 LWS_CALLBACK_UNLOCK_POLL.
212 If you use them, they protect internal and external poll list changes, but if
213 you want to use external thread access to libwebsocket_callback_on_writable()
214 you have to implement your locking here even if you don't use external
217 If you will use another thread for this, take a lot of care about managing
218 your list of live wsi by doing it from ESTABLISHED and CLOSED callbacks
219 (with your own locking).
221 If you configure cmake with -DLWS_WITH_LIBEV=1 then the code allowing the libev
222 eventloop instead of the default poll() one will also be compiled in. But to
223 use it, you must also set the LWS_SERVER_OPTION_LIBEV flag on the context
224 creation info struct options member.
226 IPV6 is supported and enabled by default except for Windows, you can disable
227 the support at build-time by giving -DLWS_IPV6=, and disable use of it even if
228 compiled in by making sure the flag LWS_SERVER_OPTION_DISABLE_IPV6 is set on
229 the context creation info struct options member.
231 You can give LWS_SERVER_OPTION_DISABLE_OS_CA_CERTS option flag to
232 guarantee the OS CAs will not be used, even if that support was selected at
235 Optional "token limits" may be enforced by setting the member "token_limits"
236 in struct lws_context_creation_info to point to a struct lws_token_limits.
237 NULL means no token limits used for compatibility.
243 Extra optional argument to libwebsockets_serve_http_file() allows injecion
244 of HTTP headers into the canned response. Eg, cookies may be added like
245 that without getting involved in having to send the header by hand.
247 A new info member http_proxy_address may be used at context creation time to
248 set the http proxy. If non-NULL, it overrides http_proxy environment var.
250 Cmake supports LWS_SSL_CLIENT_USE_OS_CA_CERTS defaulting to on, which gets
251 the client to use the OS CA Roots. If you're worried somebody with the
252 ability to forge for force creation of a client cert from the root CA in
253 your OS, you should disable this since your selfsigned $0 cert is a lot safer

314 - You can now call libwebsocket_callback_on_writable() on http connectons,
315 and get a LWS_CALLBACK_HTTP_WRITEABLE callback, the same way you can
316 regulate writes with a websocket protocol connection.
318 - A new member in the context creation parameter struct "ssl_cipher_list" is
319 added, replacing CIPHERS_LIST_STRING. NULL means use the ssl library
320 default list of ciphers.
322 - Not really an api addition, but libwebsocket_service_fd() will now zero
323 the revents field of the pollfd it was called with if it handled the
324 descriptor. So you can tell if it is a non-lws fd by checking revents
325 after the service call... if it's still nonzero, the descriptor
326 belongs to you and you need to take care of it.
328 - libwebsocket_rx_flow_allow_all_protocol(protocol) will unthrottle all
329 connections with the established protocol. It's designed to be
330 called from user server code when it sees it can accept more input
331 and may have throttled connections using the server rx flow apis
332 while it was unable to accept any other input The user server code
333 then does not have to try to track while connections it choked, this
334 will free up all of them in one call.
336 - there's a new, optional callback LWS_CALLBACK_CLOSED_HTTP which gets
337 called when an HTTP protocol socket closes
339 - for LWS_CALLBACK_FILTER_PROTOCOL_CONNECTION callback, the user_space alloc
340 has already been done before the callback happens. That means we can
341 use the user parameter to the callback to contain the user pointer, and
342 move the protocol name to the "in" parameter. The docs for this
343 callback are also updated to reflect how to check headers in there.
345 - libwebsocket_client_connect() is now properly nonblocking and async. See
346 README.coding and test-client.c for information on the callbacks you
347 can rely on controlling the async connection period with.
349 - if your OS does not support the http_proxy environment variable convention
350 (eg, reportedly OSX), you can use a new api libwebsocket_set_proxy()
351 to set the proxy details in between context creation and the connection
352 action. For OSes that support http_proxy, that's used automatically.
357 - the external poll callbacks now get the socket descriptor coming from the
358 "in" parameter. The user parameter provides the user_space for the
359 wsi as it normally does on the other callbacks.
360 LWS_CALLBACK_FILTER_NETWORK_CONNECTION also has the socket descriptor
361 delivered by @in now instead of @user.
363 - libwebsocket_write() now returns -1 for error, or the amount of data
364 actually accepted for send. Under load, the OS may signal it is
365 ready to send new data on the socket, but have only a restricted
366 amount of memory to buffer the packet compared to usual.
372 - libwebsocket_ensure_user_space() is removed from the public api, if you
373 were using it to get user_space, you need to adapt your code to only
374 use user_space inside the user callback.
376 - CIPHERS_LIST_STRING is removed
378 - autotools build has been removed. See README.build for info on how to
379 use CMake for your platform
382 v1.21-chrome26-firefox18
383 ========================
385 - Fixes buffer overflow bug in max frame size handling if you used the
386 default protocol buffer size. If you declared rx_buffer_size in your
387 protocol, which is recommended anyway, your code was unaffected.

442 - lws_get_library_version() returns a const char * with a string like
443 "1.1 9e7f737", representing the library version from configure.ac
444 and the git HEAD hash the library was built from
446 - TCP Keepalive can now optionally be applied to all lws sockets, on Linux
447 also with controllable timeout, number of probes and probe interval.
448 (On BSD type OS, you can only use system default settings for the
449 timing and retries, although enabling it is supported by setting
450 ka_time to nonzero, the exact value has no meaning.)
451 This enables detection of idle connections which are logically okay,
452 but are in fact dead, due to network connectivity issues at the server,
453 client, or any intermediary. By default it's not enabled, but you
454 can enable it by setting a non-zero timeout (in seconds) at the new
455 ka_time member at context creation time.
457 - Two new optional user callbacks added, LWS_CALLBACK_PROTOCOL_DESTROY which
458 is called one-time per protocol as the context is being destroyed, and
459 LWS_CALLBACK_PROTOCOL_INIT which is called when the context is created
460 and the protocols are added, again it's a one-time affair.
461 This lets you manage per-protocol allocations properly including
462 cleaning up after yourself when the server goes down.
467 - libwebsocket_create_context() has changed from taking a ton of parameters
468 to just taking a pointer to a struct containing the parameters. The
469 struct lws_context_creation_info is in libwebsockets.h, the members
470 are in the same order as when they were parameters to the call
471 previously. The test apps are all updated accordingly so you can
472 see example code there.
474 - Header tokens are now deleted after the websocket connection is
475 established. Not just the header data is saved, but the pointer and
476 length array is also removed from (union) scope saving several hundred
477 bytes per connection once it is established
479 - struct libwebsocket_protocols has a new member rx_buffer_size, this
480 controls rx buffer size per connection of that protocol now. Sources
481 for apps built against older versions of the library won't declare
482 this in their protocols, defaulting it to 0. Zero buffer is legal,
483 it causes a default buffer to be allocated (currently 4096)
485 If you want to receive only atomic frames in your user callback, you
486 should set this to greater than your largest frame size. If a frame
487 comes that exceeds that, no error occurs but the callback happens as
488 soon as the buffer limit is reached, and again if it is reached again
489 or the frame completes. You can detect that has happened by seeing
490 there is still frame content pending using
491 libwebsockets_remaining_packet_payload()
493 By correctly setting this, you can save a lot of memory when your
494 protocol has small frames (see the test server and client sources).
496 - LWS_MAX_HEADER_LEN now defaults to 1024 and is the total amount of known
497 header payload lws can cope with, that includes the GET URL, origin
498 etc. Headers not understood by lws are ignored and their payload
499 not included in this.
505 - The configuration-time option MAX_USER_RX_BUFFER has been replaced by a
506 buffer size chosen per-protocol. For compatibility, there's a default
507 of 4096 rx buffer, but user code should set the appropriate size for
510 - LWS_INITIAL_HDR_ALLOC and LWS_ADDITIONAL_HDR_ALLOC are no longer needed
511 and have been removed. There's a new header management scheme that
512 handles them in a much more compact way.
514 - libwebsockets_hangup_on_client() is removed. If you want to close the
515 connection you must do so from the user callback and by returning
518 - libwebsocket_close_and_free_session() is now private to the library code
519 only and not exposed for user code. If you want to close the
520 connection, you must do so from the user callback by returning -1
527 - Cmake project file added, aimed initially at Windows support: this replaces
528 the visual studio project files that were in the tree until now.
530 - CyaSSL now supported in place of OpenSSL (--use-cyassl on configure)
532 - PATH_MAX or MAX_PATH no longer needed
534 - cutomizable frame rx buffer size by protocol
536 - optional TCP keepalive so dead peers can be detected, can be enabled at
537 context-creation time
539 - valgrind-clean: no SSL or CyaSSL: completely clean. With OpenSSL, 88 bytes
540 lost at OpenSSL library init and symptomless reports of uninitialized
541 memory usage... seems to be a known and ignored problem at OpenSSL
543 - By default debug is enabled and the library is built for -O0 -g to faclitate
544 that. Use --disable-debug configure option to build instead with -O4
545 and no -g (debug info), obviously providing best performance and
548 - 1.0 introduced some code to try to not deflate small frames, however this
549 seems to break when confronted with a mixture of frames above and
550 below the threshold, so it's removed. Veto the compression extension
551 in your user callback if you will typically have very small frames.
553 - There are many memory usage improvements, both a reduction in malloc/
554 realloc and architectural changes. A websocket connection now
555 consumes only 296 bytes with SSL or 272 bytes without on x86_64,
556 during header processing an additional 1262 bytes is allocated in a
557 single malloc, but is freed when the websocket connection starts.
558 The RX frame buffer defined by the protocol in user
559 code is also allocated per connection, this represents the largest
560 frame you can receive atomically in that protocol.
562 - On ARM9 build, just http+ws server no extensions or ssl, <12Kbytes .text
563 and 112 bytes per connection (+1328 only during header processing)

646 - libwebsockets_serve_http_file() now takes a context as first argument
648 - libwebsockets_get_peer_addresses() now takes a context and wsi as first
655 - lwsl_...() logging apis, default to stderr but retargetable by user code;
656 may be used also by user code
658 - lws_set_log_level() set which logging apis are able to emit (defaults to
659 notice, warn, err severities), optionally set the emit callback
661 - lwsl_emit_syslog() helper callback emits to syslog
663 - lws_daemonize() helper code that forks the app into a headless daemon
664 properly, maintains a lock file with pid in suitable for sysvinit etc to
667 - LWS_CALLBACK_HTTP_FILE_COMPLETION callback added since http file
668 transfer is now asynchronous (see test server code)
670 - lws_frame_is_binary() from a wsi pointer, let you know if the received
671 data was sent in BINARY mode
677 - libwebsockets_fork_service_loop() - no longer supported (had intractable problems)
678 arrange your code to act from the user callback instead from same
679 process context as the service loop
681 - libwebsockets_broadcast() - use libwebsocket_callback_on_writable[_all_protocol]()
682 instead from same process context as the service loop. See the test apps
685 - x-google-mux() removed until someone wants it
687 - pre -v13 (ancient) protocol support removed
693 - echo test server and client compatible with echo.websocket.org added
695 - many new configure options (see README.build) to reduce footprint of the
696 library to what you actually need, eg, --without-client and
699 - http + websocket server can build to as little as 12K .text for ARM
701 - no more MAX_CLIENTS limitation; adapts to support the max number of fds
702 allowed to the process by ulimit, defaults to 1024 on Fedora and
703 Ubuntu. Use ulimit to control this without needing to configure
704 the library. Code here is smaller and faster.
706 - adaptive ratio of listen socket to connection socket service allows
707 good behaviour under Apache ab test load. Tested with thousands
708 of simultaneous connections
710 - reduction in per-connection memory footprint by moving to a union to hold
711 mutually-exclusive state for the connection
713 - robustness: Out of Memory taken care of for all allocation code now
715 - internal getifaddrs option if your toolchain lacks it (some uclibc)
717 - configurable memory limit for deflate operations
719 - improvements in SSL code nonblocking operation, possible hang solved,
720 some SSL operations broken down into pollable states so there is
721 no library blocking, timeout coverage for SSL_connect
723 - extpoll test server merged into single test server source
725 - robustness: library should deal with all recoverable socket conditions
727 - rx flowcontrol for backpressure notification fixed and implmeneted
728 correctly in the test server
730 - optimal lexical parser added for header processing; all headers in a
731 single 276-byte state table
733 - latency tracking api added (configure --with-latency)
735 - Improved in-tree documentation, REAME.build, README.coding,
736 README.test-apps, changelog
741 v1.0-chrome25-firefox17 (6cd1ea9b005933f)
