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
17 - libwebsocket_create_context() has changed from taking a ton of parameters
18 to just taking a pointer to a struct containing the parameters. The
19 struct lws_context_creation_info is in libwebsockets.h, the members
20 are in the same order as when they were parameters to the call
21 previously. The test apps are all updated accordingly so you can
22 see example code there.
24 - Header tokens are now deleted after the websocket connection is
25 established. Not just the header data is saved, but the pointer and
26 length array is also removed from (union) scope saving several hundred
27 bytes per connection once it is established
29 - struct libwebsocket_protocols has a new member rx_buffer_size, this
30 controls rx buffer size per connection of that protocol now. Sources
31 for apps built against older versions of the library won't declare
32 this in their protocols, defaulting it to 0. Zero buffer is legal,
33 it causes a default buffer to be allocated (currently 4096)
35 If you want to receive only atomic frames in your user callback, you
36 should set this to greater than your largest frame size. If a frame
37 comes that exceeds that, no error occurs but the callback happens as
38 soon as the buffer limit is reached, and again if it is reached again
39 or the frame completes. You can detect that has happened by seeing
40 there is still frame content pending using
41 libwebsockets_remaining_packet_payload()
43 By correctly setting this, you can save a lot of memory when your
44 protocol has small frames (see the test server and client sources).
50 The configuration-time option MAX_USER_RX_BUFFER has been replaced by a
51 buffer size chosen per-protocol. For compatibility, there's a default of
52 4096 rx buffer, but user code should set the appropriate size for the
59 - Cmake project file added, aimed initially at Windows support: this replaces
60 the visual studio project files that were in the tree until now.
62 - PATH_MAX or MAX_PATH no longer needed
64 - cutomizable frame rx buffer size by protocol

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