4 (development since 1.1....)
9 - lws_get_library_version() returns a const char * with a string like
10 "1.1 9e7f737", representing the library version from configure.ac
11 and the git HEAD hash the library was built from
13 - TCP Keepalive can now optionally be applied to all lws sockets, on Linux
14 also with controllable timeout, number of probes and probe interval.
15 (On BSD type OS, you can only use system default settings for the
16 timing and retries, although enabling it is supported by setting
17 ka_time to nonzero, the exact value has no meaning.)
18 This enables detection of idle connections which are logically okay,
19 but are in fact dead, due to network connectivity issues at the server,
20 client, or any intermediary. By default it's not enabled, but you
21 can enable it by setting a non-zero timeout (in seconds) at the new
22 ka_time member at context creation time.
28 - libwebsocket_create_context() has changed from taking a ton of parameters
29 to just taking a pointer to a struct containing the parameters. The
30 struct lws_context_creation_info is in libwebsockets.h, the members
31 are in the same order as when they were parameters to the call
32 previously. The test apps are all updated accordingly so you can
33 see example code there.
35 - Header tokens are now deleted after the websocket connection is
36 established. Not just the header data is saved, but the pointer and
37 length array is also removed from (union) scope saving several hundred
38 bytes per connection once it is established
40 - struct libwebsocket_protocols has a new member rx_buffer_size, this
41 controls rx buffer size per connection of that protocol now. Sources
42 for apps built against older versions of the library won't declare
43 this in their protocols, defaulting it to 0. Zero buffer is legal,
44 it causes a default buffer to be allocated (currently 4096)
46 If you want to receive only atomic frames in your user callback, you
47 should set this to greater than your largest frame size. If a frame
48 comes that exceeds that, no error occurs but the callback happens as
49 soon as the buffer limit is reached, and again if it is reached again
50 or the frame completes. You can detect that has happened by seeing
51 there is still frame content pending using
52 libwebsockets_remaining_packet_payload()
54 By correctly setting this, you can save a lot of memory when your
55 protocol has small frames (see the test server and client sources).
61 The configuration-time option MAX_USER_RX_BUFFER has been replaced by a
62 buffer size chosen per-protocol. For compatibility, there's a default of
63 4096 rx buffer, but user code should set the appropriate size for the
70 - Cmake project file added, aimed initially at Windows support: this replaces
71 the visual studio project files that were in the tree until now.
73 - PATH_MAX or MAX_PATH no longer needed
75 - cutomizable frame rx buffer size by protocol

159 - libwebsockets_serve_http_file() now takes a context as first argument
161 - libwebsockets_get_peer_addresses() now takes a context and wsi as first
168 - lwsl_...() logging apis, default to stderr but retargetable by user code;
169 may be used also by user code
171 - lws_set_log_level() set which logging apis are able to emit (defaults to
172 notice, warn, err severities), optionally set the emit callback
174 - lwsl_emit_syslog() helper callback emits to syslog
176 - lws_daemonize() helper code that forks the app into a headless daemon
177 properly, maintains a lock file with pid in suitable for sysvinit etc to
180 - LWS_CALLBACK_HTTP_FILE_COMPLETION callback added since http file
181 transfer is now asynchronous (see test server code)
183 - lws_frame_is_binary() from a wsi pointer, let you know if the received
184 data was sent in BINARY mode
190 - libwebsockets_fork_service_loop() - no longer supported (had intractable problems)
191 arrange your code to act from the user callback instead from same
192 process context as the service loop
194 - libwebsockets_broadcast() - use libwebsocket_callback_on_writable[_all_protocol]()
195 instead from same process context as the service loop. See the test apps
198 - x-google-mux() removed until someone wants it
200 - pre -v13 (ancient) protocol support removed
206 - echo test server and client compatible with echo.websocket.org added
208 - many new configure options (see README.build) to reduce footprint of the
209 library to what you actually need, eg, --without-client and
212 - http + websocket server can build to as little as 12K .text for ARM
214 - no more MAX_CLIENTS limitation; adapts to support the max number of fds
215 allowed to the process by ulimit, defaults to 1024 on Fedora and
216 Ubuntu. Use ulimit to control this without needing to configure
217 the library. Code here is smaller and faster.
219 - adaptive ratio of listen socket to connection socket service allows
220 good behaviour under Apache ab test load. Tested with thousands
221 of simultaneous connections
223 - reduction in per-connection memory footprint by moving to a union to hold
224 mutually-exclusive state for the connection
226 - robustness: Out of Memory taken care of for all allocation code now
228 - internal getifaddrs option if your toolchain lacks it (some uclibc)
230 - configurable memory limit for deflate operations
232 - improvements in SSL code nonblocking operation, possible hang solved,
233 some SSL operations broken down into pollable states so there is
234 no library blocking, timeout coverage for SSL_connect
236 - extpoll test server merged into single test server source
238 - robustness: library should deal with all recoverable socket conditions
240 - rx flowcontrol for backpressure notification fixed and implmeneted
241 correctly in the test server
243 - optimal lexical parser added for header processing; all headers in a
244 single 276-byte state table
246 - latency tracking api added (configure --with-latency)
248 - Improved in-tree documentation, REAME.build, README.coding,
249 README.test-apps, changelog
254 v1.0-chrome25-firefox17 (6cd1ea9b005933f)
