9 Extra optional argument to libwebsockets_serve_http_file() allows injecion
10 of HTTP headers into the canned response. Eg, cookies may be added like
11 that without getting involved in having to send the header by hand.

72 - You can now call libwebsocket_callback_on_writable() on http connectons,
73 and get a LWS_CALLBACK_HTTP_WRITEABLE callback, the same way you can
74 regulate writes with a websocket protocol connection.
76 - A new member in the context creation parameter struct "ssl_cipher_list" is
77 added, replacing CIPHERS_LIST_STRING. NULL means use the ssl library
78 default list of ciphers.
80 - Not really an api addition, but libwebsocket_service_fd() will now zero
81 the revents field of the pollfd it was called with if it handled the
82 descriptor. So you can tell if it is a non-lws fd by checking revents
83 after the service call... if it's still nonzero, the descriptor
84 belongs to you and you need to take care of it.
86 - libwebsocket_rx_flow_allow_all_protocol(protocol) will unthrottle all
87 connections with the established protocol. It's designed to be
88 called from user server code when it sees it can accept more input
89 and may have throttled connections using the server rx flow apis
90 while it was unable to accept any other input The user server code
91 then does not have to try to track while connections it choked, this
92 will free up all of them in one call.
94 - there's a new, optional callback LWS_CALLBACK_CLOSED_HTTP which gets
95 called when an HTTP protocol socket closes
97 - for LWS_CALLBACK_FILTER_PROTOCOL_CONNECTION callback, the user_space alloc
98 has already been done before the callback happens. That means we can
99 use the user parameter to the callback to contain the user pointer, and
100 move the protocol name to the "in" parameter. The docs for this
101 callback are also updated to reflect how to check headers in there.
103 - libwebsocket_client_connect() is now properly nonblocking and async. See
104 README.coding and test-client.c for information on the callbacks you
105 can rely on controlling the async connection period with.
107 - if your OS does not support the http_proxy environment variable convention
108 (eg, reportedly OSX), you can use a new api libwebsocket_set_proxy()
109 to set the proxy details inbetween context creation and the connection
110 action. For OSes that support http_proxy, that's used automatically.
115 - the external poll callbacks now get the socket descriptor coming from the
116 "in" parameter. The user parameter provides the user_space for the
117 wsi as it normally does on the other callbacks.
118 LWS_CALLBACK_FILTER_NETWORK_CONNECTION also has the socket descriptor
119 delivered by @in now instead of @user.
121 - libwebsocket_write() now returns -1 for error, or the amount of data
122 actually accepted for send. Under load, the OS may signal it is
123 ready to send new data on the socket, but have only a restricted
124 amount of memory to buffer the packet compared to usual.
130 - libwebsocket_ensure_user_space() is removed from the public api, if you
131 were using it to get user_space, you need to adapt your code to only
132 use user_space inside the user callback.
134 - CIPHERS_LIST_STRING is removed
136 - autotools build has been removed. See README.build for info on how to
137 use CMake for your platform
140 v1.21-chrome26-firefox18
141 ========================
143 - Fixes buffer overflow bug in max frame size handling if you used the
144 default protocol buffer size. If you declared rx_buffer_size in your
145 protocol, which is recommended anyway, your code was unaffected.

200 - lws_get_library_version() returns a const char * with a string like
201 "1.1 9e7f737", representing the library version from configure.ac
202 and the git HEAD hash the library was built from
204 - TCP Keepalive can now optionally be applied to all lws sockets, on Linux
205 also with controllable timeout, number of probes and probe interval.
206 (On BSD type OS, you can only use system default settings for the
207 timing and retries, although enabling it is supported by setting
208 ka_time to nonzero, the exact value has no meaning.)
209 This enables detection of idle connections which are logically okay,
210 but are in fact dead, due to network connectivity issues at the server,
211 client, or any intermediary. By default it's not enabled, but you
212 can enable it by setting a non-zero timeout (in seconds) at the new
213 ka_time member at context creation time.
215 - Two new optional user callbacks added, LWS_CALLBACK_PROTOCOL_DESTROY which
216 is called one-time per protocol as the context is being destroyed, and
217 LWS_CALLBACK_PROTOCOL_INIT which is called when the context is created
218 and the protocols are added, again it's a one-time affair.
219 This lets you manage per-protocol allocations properly including
220 cleaning up after yourself when the server goes down.
225 - libwebsocket_create_context() has changed from taking a ton of parameters
226 to just taking a pointer to a struct containing the parameters. The
227 struct lws_context_creation_info is in libwebsockets.h, the members
228 are in the same order as when they were parameters to the call
229 previously. The test apps are all updated accordingly so you can
230 see example code there.
232 - Header tokens are now deleted after the websocket connection is
233 established. Not just the header data is saved, but the pointer and
234 length array is also removed from (union) scope saving several hundred
235 bytes per connection once it is established
237 - struct libwebsocket_protocols has a new member rx_buffer_size, this
238 controls rx buffer size per connection of that protocol now. Sources
239 for apps built against older versions of the library won't declare
240 this in their protocols, defaulting it to 0. Zero buffer is legal,
241 it causes a default buffer to be allocated (currently 4096)
243 If you want to receive only atomic frames in your user callback, you
244 should set this to greater than your largest frame size. If a frame
245 comes that exceeds that, no error occurs but the callback happens as
246 soon as the buffer limit is reached, and again if it is reached again
247 or the frame completes. You can detect that has happened by seeing
248 there is still frame content pending using
249 libwebsockets_remaining_packet_payload()
251 By correctly setting this, you can save a lot of memory when your
252 protocol has small frames (see the test server and client sources).
254 - LWS_MAX_HEADER_LEN now defaults to 1024 and is the total amount of known
255 header payload lws can cope with, that includes the GET URL, origin
256 etc. Headers not understood by lws are ignored and their payload
257 not included in this.
263 - The configuration-time option MAX_USER_RX_BUFFER has been replaced by a
264 buffer size chosen per-protocol. For compatibility, there's a default
265 of 4096 rx buffer, but user code should set the appropriate size for
268 - LWS_INITIAL_HDR_ALLOC and LWS_ADDITIONAL_HDR_ALLOC are no longer needed
269 and have been removed. There's a new header management scheme that
270 handles them in a much more compact way.
272 - libwebsockets_hangup_on_client() is removed. If you want to close the
273 connection you must do so from the user callback and by returning
276 - libwebsocket_close_and_free_session() is now private to the library code
277 only and not exposed for user code. If you want to close the
278 connection, you must do so from the user callback by returning -1
285 - Cmake project file added, aimed initially at Windows support: this replaces
286 the visual studio project files that were in the tree until now.
288 - CyaSSL now supported in place of OpenSSL (--use-cyassl on configure)
290 - PATH_MAX or MAX_PATH no longer needed
292 - cutomizable frame rx buffer size by protocol
294 - optional TCP keepalive so dead peers can be detected, can be enabled at
295 context-creation time
297 - valgrind-clean: no SSL or CyaSSL: completely clean. With OpenSSL, 88 bytes
298 lost at OpenSSL library init and symptomless reports of uninitialized
299 memory usage... seems to be a known and ignored problem at OpenSSL
301 - By default debug is enabled and the library is built for -O0 -g to faclitate
302 that. Use --disable-debug configure option to build instead with -O4
303 and no -g (debug info), obviously providing best performance and
306 - 1.0 introduced some code to try to not deflate small frames, however this
307 seems to break when confronted with a mixture of frames above and
308 below the threshold, so it's removed. Veto the compression extension
309 in your user callback if you will typically have very small frames.
311 - There are many memory usage improvements, both a reduction in malloc/
312 realloc and architectural changes. A websocket connection now
313 consumes only 296 bytes with SSL or 272 bytes without on x86_64,
314 during header processing an additional 1262 bytes is allocated in a
315 single malloc, but is freed when the websocket connection starts.
316 The RX frame buffer defined by the protocol in user
317 code is also allocated per connection, this represents the largest
318 frame you can receive atomically in that protocol.
320 - On ARM9 build, just http+ws server no extensions or ssl, <12Kbytes .text
321 and 112 bytes per connection (+1328 only during header processing)

404 - libwebsockets_serve_http_file() now takes a context as first argument
406 - libwebsockets_get_peer_addresses() now takes a context and wsi as first
413 - lwsl_...() logging apis, default to stderr but retargetable by user code;
414 may be used also by user code
416 - lws_set_log_level() set which logging apis are able to emit (defaults to
417 notice, warn, err severities), optionally set the emit callback
419 - lwsl_emit_syslog() helper callback emits to syslog
421 - lws_daemonize() helper code that forks the app into a headless daemon
422 properly, maintains a lock file with pid in suitable for sysvinit etc to
425 - LWS_CALLBACK_HTTP_FILE_COMPLETION callback added since http file
426 transfer is now asynchronous (see test server code)
428 - lws_frame_is_binary() from a wsi pointer, let you know if the received
429 data was sent in BINARY mode
435 - libwebsockets_fork_service_loop() - no longer supported (had intractable problems)
436 arrange your code to act from the user callback instead from same
437 process context as the service loop
439 - libwebsockets_broadcast() - use libwebsocket_callback_on_writable[_all_protocol]()
440 instead from same process context as the service loop. See the test apps
443 - x-google-mux() removed until someone wants it
445 - pre -v13 (ancient) protocol support removed
451 - echo test server and client compatible with echo.websocket.org added
453 - many new configure options (see README.build) to reduce footprint of the
454 library to what you actually need, eg, --without-client and
457 - http + websocket server can build to as little as 12K .text for ARM
459 - no more MAX_CLIENTS limitation; adapts to support the max number of fds
460 allowed to the process by ulimit, defaults to 1024 on Fedora and
461 Ubuntu. Use ulimit to control this without needing to configure
462 the library. Code here is smaller and faster.
464 - adaptive ratio of listen socket to connection socket service allows
465 good behaviour under Apache ab test load. Tested with thousands
466 of simultaneous connections
468 - reduction in per-connection memory footprint by moving to a union to hold
469 mutually-exclusive state for the connection

475 - configurable memory limit for deflate operations
477 - improvements in SSL code nonblocking operation, possible hang solved,
478 some SSL operations broken down into pollable states so there is
479 no library blocking, timeout coverage for SSL_connect
481 - extpoll test server merged into single test server source
483 - robustness: library should deal with all recoverable socket conditions
485 - rx flowcontrol for backpressure notification fixed and implmeneted
486 correctly in the test server
488 - optimal lexical parser added for header processing; all headers in a
489 single 276-byte state table
491 - latency tracking api added (configure --with-latency)
