9 LWS_CALLBACK_CLIENT_CONNECTION_ERROR may provide an error string if in is
10 non-NULL. If so, the string has length len.
12 v1.4-chrome43-firefox36
13 =======================
18 There's a new member in the info struct used to control context creation,
19 ssl_private_key_password, which allows passing into lws the passphrase on
22 There's a new member in struct protocols, id, which is ignored by lws but can
23 be used by the user code to mark the selected protocol by user-defined version
24 or capabliity flag information, for the case multiple versions of a protocol are
27 int lws_is_ssl(wsi) added to allow user code to know if the connection was made
28 over ssl or not. If LWS_SERVER_OPTION_ALLOW_NON_SSL_ON_SSL_PORT is used, both
29 ssl and non-ssl connections are possible and may need to be treated differently
32 int lws_partial_buffered(wsi) added... should be checked after any
33 libwebsocket_write that will be followed by another libwebsocket_write inside
34 the same writeable callback. If set, you can't do any more writes until the
35 writeable callback is called again. If you only do one write per writeable callback,
38 HTTP2-related: HTTP2 changes how headers are handled, lws now has new version-
39 agnositic header creation APIs. These do the right thing depending on each
40 connection's HTTP version without the user code having to know or care, except
41 to make sure to use the new APIs for headers (test-server is updated to use
42 them already, so look there for examples)
44 The APIs "render" the headers into a user-provided buffer and bump *p as it
45 is used. If *p reaches end, then the APIs return nonzero for error.
47 LWS_VISIBLE LWS_EXTERN int
48 lws_add_http_header_status(struct libwebsocket_context *context,
49 struct libwebsocket *wsi,
54 Start a response header reporting status like 200, 500, etc
56 LWS_VISIBLE LWS_EXTERN int
57 lws_add_http_header_by_name(struct libwebsocket_context *context,
58 struct libwebsocket *wsi,
59 const unsigned char *name,
60 const unsigned char *value,
65 Add a header like name: value in HTTP1.x
67 LWS_VISIBLE LWS_EXTERN int
68 lws_finalize_http_header(struct libwebsocket_context *context,
69 struct libwebsocket *wsi,
73 Finish off the headers, like add the extra \r\n in HTTP1.x
75 LWS_VISIBLE LWS_EXTERN int
76 lws_add_http_header_by_token(struct libwebsocket_context *context,
77 struct libwebsocket *wsi,
78 enum lws_token_indexes token,
79 const unsigned char *value,
84 Add a header by using a lws token as the name part. In HTTP2, this can be
85 compressed to one or two bytes.
91 protocols struct member no_buffer_all_partial_tx is removed. Under some
92 conditions like rewriting extention such as compression in use, the built-in
93 partial send buffering is the only way to deal with the problem, so turning
100 HTTP2-related: API libwebsockets_serve_http_file() takes an extra parameter at
103 int other_headers_len)
105 If you are providing other headers, they must be generated using the new
106 HTTP-version-agnostic APIs, and you must provide the length of them using this
107 additional parameter.
109 struct lws_context_creation_info now has an additional member
110 SSL_CTX *provided_client_ssl_ctx you may set to an externally-initialized
111 SSL_CTX managed outside lws. Defaulting to zero keeps the existing behaviour of
112 lws managing the context, if you memset the struct to 0 or have as a filescope
113 initialized struct in bss, no need to change anything.

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

306 - You can now call libwebsocket_callback_on_writable() on http connectons,
307 and get a LWS_CALLBACK_HTTP_WRITEABLE callback, the same way you can
308 regulate writes with a websocket protocol connection.
310 - A new member in the context creation parameter struct "ssl_cipher_list" is
311 added, replacing CIPHERS_LIST_STRING. NULL means use the ssl library
312 default list of ciphers.
314 - Not really an api addition, but libwebsocket_service_fd() will now zero
315 the revents field of the pollfd it was called with if it handled the
316 descriptor. So you can tell if it is a non-lws fd by checking revents
317 after the service call... if it's still nonzero, the descriptor
318 belongs to you and you need to take care of it.
320 - libwebsocket_rx_flow_allow_all_protocol(protocol) will unthrottle all
321 connections with the established protocol. It's designed to be
322 called from user server code when it sees it can accept more input
323 and may have throttled connections using the server rx flow apis
324 while it was unable to accept any other input The user server code
325 then does not have to try to track while connections it choked, this
326 will free up all of them in one call.
328 - there's a new, optional callback LWS_CALLBACK_CLOSED_HTTP which gets
329 called when an HTTP protocol socket closes
331 - for LWS_CALLBACK_FILTER_PROTOCOL_CONNECTION callback, the user_space alloc
332 has already been done before the callback happens. That means we can
333 use the user parameter to the callback to contain the user pointer, and
334 move the protocol name to the "in" parameter. The docs for this
335 callback are also updated to reflect how to check headers in there.
337 - libwebsocket_client_connect() is now properly nonblocking and async. See
338 README.coding and test-client.c for information on the callbacks you
339 can rely on controlling the async connection period with.
341 - if your OS does not support the http_proxy environment variable convention
342 (eg, reportedly OSX), you can use a new api libwebsocket_set_proxy()
343 to set the proxy details inbetween context creation and the connection
344 action. For OSes that support http_proxy, that's used automatically.
349 - the external poll callbacks now get the socket descriptor coming from the
350 "in" parameter. The user parameter provides the user_space for the
351 wsi as it normally does on the other callbacks.
352 LWS_CALLBACK_FILTER_NETWORK_CONNECTION also has the socket descriptor
353 delivered by @in now instead of @user.
355 - libwebsocket_write() now returns -1 for error, or the amount of data
356 actually accepted for send. Under load, the OS may signal it is
357 ready to send new data on the socket, but have only a restricted
358 amount of memory to buffer the packet compared to usual.
364 - libwebsocket_ensure_user_space() is removed from the public api, if you
365 were using it to get user_space, you need to adapt your code to only
366 use user_space inside the user callback.
368 - CIPHERS_LIST_STRING is removed
370 - autotools build has been removed. See README.build for info on how to
371 use CMake for your platform
374 v1.21-chrome26-firefox18
375 ========================
377 - Fixes buffer overflow bug in max frame size handling if you used the
378 default protocol buffer size. If you declared rx_buffer_size in your
379 protocol, which is recommended anyway, your code was unaffected.

434 - lws_get_library_version() returns a const char * with a string like
435 "1.1 9e7f737", representing the library version from configure.ac
436 and the git HEAD hash the library was built from
438 - TCP Keepalive can now optionally be applied to all lws sockets, on Linux
439 also with controllable timeout, number of probes and probe interval.
440 (On BSD type OS, you can only use system default settings for the
441 timing and retries, although enabling it is supported by setting
442 ka_time to nonzero, the exact value has no meaning.)
443 This enables detection of idle connections which are logically okay,
444 but are in fact dead, due to network connectivity issues at the server,
445 client, or any intermediary. By default it's not enabled, but you
446 can enable it by setting a non-zero timeout (in seconds) at the new
447 ka_time member at context creation time.
449 - Two new optional user callbacks added, LWS_CALLBACK_PROTOCOL_DESTROY which
450 is called one-time per protocol as the context is being destroyed, and
451 LWS_CALLBACK_PROTOCOL_INIT which is called when the context is created
452 and the protocols are added, again it's a one-time affair.
453 This lets you manage per-protocol allocations properly including
454 cleaning up after yourself when the server goes down.
459 - libwebsocket_create_context() has changed from taking a ton of parameters
460 to just taking a pointer to a struct containing the parameters. The
461 struct lws_context_creation_info is in libwebsockets.h, the members
462 are in the same order as when they were parameters to the call
463 previously. The test apps are all updated accordingly so you can
464 see example code there.
466 - Header tokens are now deleted after the websocket connection is
467 established. Not just the header data is saved, but the pointer and
468 length array is also removed from (union) scope saving several hundred
469 bytes per connection once it is established
471 - struct libwebsocket_protocols has a new member rx_buffer_size, this
472 controls rx buffer size per connection of that protocol now. Sources
473 for apps built against older versions of the library won't declare
474 this in their protocols, defaulting it to 0. Zero buffer is legal,
475 it causes a default buffer to be allocated (currently 4096)
477 If you want to receive only atomic frames in your user callback, you
478 should set this to greater than your largest frame size. If a frame
479 comes that exceeds that, no error occurs but the callback happens as
480 soon as the buffer limit is reached, and again if it is reached again
481 or the frame completes. You can detect that has happened by seeing
482 there is still frame content pending using
483 libwebsockets_remaining_packet_payload()
485 By correctly setting this, you can save a lot of memory when your
486 protocol has small frames (see the test server and client sources).
488 - LWS_MAX_HEADER_LEN now defaults to 1024 and is the total amount of known
489 header payload lws can cope with, that includes the GET URL, origin
490 etc. Headers not understood by lws are ignored and their payload
491 not included in this.
497 - The configuration-time option MAX_USER_RX_BUFFER has been replaced by a
498 buffer size chosen per-protocol. For compatibility, there's a default
499 of 4096 rx buffer, but user code should set the appropriate size for
502 - LWS_INITIAL_HDR_ALLOC and LWS_ADDITIONAL_HDR_ALLOC are no longer needed
503 and have been removed. There's a new header management scheme that
504 handles them in a much more compact way.
506 - libwebsockets_hangup_on_client() is removed. If you want to close the
507 connection you must do so from the user callback and by returning
510 - libwebsocket_close_and_free_session() is now private to the library code
511 only and not exposed for user code. If you want to close the
512 connection, you must do so from the user callback by returning -1
519 - Cmake project file added, aimed initially at Windows support: this replaces
520 the visual studio project files that were in the tree until now.
522 - CyaSSL now supported in place of OpenSSL (--use-cyassl on configure)
524 - PATH_MAX or MAX_PATH no longer needed
526 - cutomizable frame rx buffer size by protocol
528 - optional TCP keepalive so dead peers can be detected, can be enabled at
529 context-creation time
531 - valgrind-clean: no SSL or CyaSSL: completely clean. With OpenSSL, 88 bytes
532 lost at OpenSSL library init and symptomless reports of uninitialized
533 memory usage... seems to be a known and ignored problem at OpenSSL
535 - By default debug is enabled and the library is built for -O0 -g to faclitate
536 that. Use --disable-debug configure option to build instead with -O4
537 and no -g (debug info), obviously providing best performance and
540 - 1.0 introduced some code to try to not deflate small frames, however this
541 seems to break when confronted with a mixture of frames above and
542 below the threshold, so it's removed. Veto the compression extension
543 in your user callback if you will typically have very small frames.
545 - There are many memory usage improvements, both a reduction in malloc/
546 realloc and architectural changes. A websocket connection now
547 consumes only 296 bytes with SSL or 272 bytes without on x86_64,
548 during header processing an additional 1262 bytes is allocated in a
549 single malloc, but is freed when the websocket connection starts.
550 The RX frame buffer defined by the protocol in user
551 code is also allocated per connection, this represents the largest
552 frame you can receive atomically in that protocol.
554 - On ARM9 build, just http+ws server no extensions or ssl, <12Kbytes .text
555 and 112 bytes per connection (+1328 only during header processing)

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