link their program against a user-supplied version of libwebsockets.
If you link the program to a modified version of libwebsockets, then the
changes to libwebsockets must be provided under the terms of the LGPL in
sections 1, 2, and 4.
2) You do not have to provide a copy of the libwebsockets license with
programs that are linked to the libwebsockets library, nor do you have to
identify the libwebsockets license in your program or documentation as
required by section 6 of the LGPL.
However, programs must still identify their use of libwebsockets. The
following example statement can be included in user documentation to
satisfy this requirement:
"[program] is based in part on the work of the libwebsockets project
(http://libwebsockets.org)"
GNU LESSER GENERAL PUBLIC LICENSE
Version 2.1, February 1999
Copyright (C) 1991, 1999 Free Software Foundation, Inc.
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
[This is the first released version of the Lesser GPL. It also counts
as the successor of the GNU Library Public License, version 2, hence
the version number 2.1.]
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
Licenses are intended to guarantee your freedom to share and change
free software--to make sure the software is free for all its users.
This license, the Lesser General Public License, applies to some
specially designated software packages--typically libraries--of the
Free Software Foundation and other authors who decide to use it. You
can use it too, but we suggest you first think carefully about whether
this license or the ordinary General Public License is the better
strategy to use in any particular case, based on the explanations below.
When we speak of free software, we are referring to freedom of use,
not price. Our General Public Licenses are designed to make sure that
you have the freedom to distribute copies of free software (and charge
for this service if you wish); that you receive source code or can get
it if you want it; that you can change the software and use pieces of
it in new free programs; and that you are informed that you can do
these things.
To protect your rights, we need to make restrictions that forbid
distributors to deny you these rights or to ask you to surrender these
rights. These restrictions translate to certain responsibilities for
you if you distribute copies of the library or if you modify it.
For example, if you distribute copies of the library, whether gratis
or for a fee, you must give the recipients all the rights that we gave
you. You must make sure that they, too, receive or can get the source
code. If you link other code with the library, you must provide
complete object files to the recipients, so that they can relink them
with the library after making changes to the library and recompiling
it. And you must show them these terms so they know their rights.
We protect your rights with a two-step method: (1) we copyright the
library, and (2) we offer you this license, which gives you legal
permission to copy, distribute and/or modify the library.
To protect each distributor, we want to make it very clear that
there is no warranty for the free library. Also, if the library is
modified by someone else and passed on, the recipients should know
that what they have is not the original version, so that the original
author's reputation will not be affected by problems that might be
introduced by others.
Finally, software patents pose a constant threat to the existence of
any free program. We wish to make sure that a company cannot
effectively restrict the users of a free program by obtaining a
restrictive license from a patent holder. Therefore, we insist that
any patent license obtained for a version of the library must be
consistent with the full freedom of use specified in this license.
Most GNU software, including some libraries, is covered by the
ordinary GNU General Public License. This license, the GNU Lesser
General Public License, applies to certain designated libraries, and
is quite different from the ordinary General Public License. We use
this license for certain libraries in order to permit linking those
libraries into non-free programs.
When a program is linked with a library, whether statically or using
a shared library, the combination of the two is legally speaking a
combined work, a derivative of the original library. The ordinary
General Public License therefore permits such linking only if the
entire combination fits its criteria of freedom. The Lesser General
Public License permits more lax criteria for linking other code with
the library.
We call this license the "Lesser" General Public License because it
does Less to protect the user's freedom than the ordinary General
Public License. It also provides other free software developers Less
of an advantage over competing non-free programs. These disadvantages
are the reason we use the ordinary General Public License for many
libraries. However, the Lesser license provides advantages in certain
special circumstances.
For example, on rare occasions, there may be a special need to
encourage the widest possible use of a certain library, so that it becomes
a de-facto standard. To achieve this, non-free programs must be
allowed to use the library. A more frequent case is that a free
library does the same job as widely used non-free libraries. In this
case, there is little to gain by limiting the free library to free
software only, so we use the Lesser General Public License.
In other cases, permission to use a particular library in non-free
programs enables a greater number of people to use a large body of
free software. For example, permission to use the GNU C Library in
non-free programs enables many more people to use the whole GNU
operating system, as well as its variant, the GNU/Linux operating
system.
Although the Lesser General Public License is Less protective of the
users' freedom, it does ensure that the user of a program that is
linked with the Library has the freedom and the wherewithal to run
that program using a modified version of the Library.
The precise terms and conditions for copying, distribution and
modification follow. Pay close attention to the difference between a
"work based on the library" and a "work that uses the library". The
former contains code derived from the library, whereas the latter must
be combined with the library in order to run.
GNU LESSER GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library or other
program which contains a notice placed by the copyright holder or
other authorized party saying it may be distributed under the terms of
this Lesser General Public License (also called "this License").
Each licensee is addressed as "you".
A "library" means a collection of software functions and/or data
prepared so as to be conveniently linked with application programs
(which use some of those functions and data) to form executables.
The "Library", below, refers to any such software library or work
which has been distributed under these terms. A "work based on the
Library" means either the Library or any derivative work under
copyright law: that is to say, a work containing the Library or a
portion of it, either verbatim or with modifications and/or translated
straightforwardly into another language. (Hereinafter, translation is
included without limitation in the term "modification".)
"Source code" for a work means the preferred form of the work for
making modifications to it. For a library, complete source code means
all the source code for all modules it contains, plus any associated
interface definition files, plus the scripts used to control compilation
and installation of the library.
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running a program using the Library is not restricted, and output from
such a program is covered only if its contents constitute a work based
on the Library (independent of the use of the Library in a tool for
writing it). Whether that is true depends on what the Library does
and what the program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's
complete source code as you receive it, in any medium, provided that
you conspicuously and appropriately publish on each copy an
appropriate copyright notice and disclaimer of warranty; keep intact
all the notices that refer to this License and to the absence of any
warranty; and distribute a copy of this License along with the
Library.
You may charge a fee for the physical act of transferring a copy,
and you may at your option offer warranty protection in exchange for a
fee.
2. You may modify your copy or copies of the Library or any portion
of it, thus forming a work based on the Library, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices
stating that you changed the files and the date of any change.
c) You must cause the whole of the work to be licensed at no
charge to all third parties under the terms of this License.
d) If a facility in the modified Library refers to a function or a
table of data to be supplied by an application program that uses
the facility, other than as an argument passed when the facility
is invoked, then you must make a good faith effort to ensure that,
in the event an application does not supply such function or
table, the facility still operates, and performs whatever part of
its purpose remains meaningful.
(For example, a function in a library to compute square roots has
a purpose that is entirely well-defined independent of the
application. Therefore, Subsection 2d requires that any
application-supplied function or table used by this function must
be optional: if the application does not supply it, the square
root function must still compute square roots.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Library,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Library, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote
it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Library.
In addition, mere aggregation of another work not based on the Library
with the Library (or with a work based on the Library) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may opt to apply the terms of the ordinary GNU General Public
License instead of this License to a given copy of the Library. To do
this, you must alter all the notices that refer to this License, so
that they refer to the ordinary GNU General Public License, version 2,
instead of to this License. (If a newer version than version 2 of the
ordinary GNU General Public License has appeared, then you can specify
that version instead if you wish.) Do not make any other change in
these notices.
Once this change is made in a given copy, it is irreversible for
that copy, so the ordinary GNU General Public License applies to all
subsequent copies and derivative works made from that copy.
This option is useful when you wish to copy part of the code of
the Library into a program that is not a library.
4. You may copy and distribute the Library (or a portion or
derivative of it, under Section 2) in object code or executable form
under the terms of Sections 1 and 2 above provided that you accompany
it with the complete corresponding machine-readable source code, which
must be distributed under the terms of Sections 1 and 2 above on a
medium customarily used for software interchange.
If distribution of object code is made by offering access to copy
from a designated place, then offering equivalent access to copy the
source code from the same place satisfies the requirement to
distribute the source code, even though third parties are not
compelled to copy the source along with the object code.
5. A program that contains no derivative of any portion of the
Library, but is designed to work with the Library by being compiled or
linked with it, is called a "work that uses the Library". Such a
work, in isolation, is not a derivative work of the Library, and
therefore falls outside the scope of this License.
However, linking a "work that uses the Library" with the Library
creates an executable that is a derivative of the Library (because it
contains portions of the Library), rather than a "work that uses the
library". The executable is therefore covered by this License.
Section 6 states terms for distribution of such executables.
When a "work that uses the Library" uses material from a header file
that is part of the Library, the object code for the work may be a
derivative work of the Library even though the source code is not.
Whether this is true is especially significant if the work can be
linked without the Library, or if the work is itself a library. The
threshold for this to be true is not precisely defined by law.
If such an object file uses only numerical parameters, data
structure layouts and accessors, and small macros and small inline
functions (ten lines or less in length), then the use of the object
file is unrestricted, regardless of whether it is legally a derivative
work. (Executables containing this object code plus portions of the
Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may
distribute the object code for the work under the terms of Section 6.
Any executables containing that work also fall under Section 6,
whether or not they are linked directly with the Library itself.
6. As an exception to the Sections above, you may also combine or
link a "work that uses the Library" with the Library to produce a
work containing portions of the Library, and distribute that work
under terms of your choice, provided that the terms permit
modification of the work for the customer's own use and reverse
engineering for debugging such modifications.
You must give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are covered by
this License. You must supply a copy of this License. If the work
during execution displays copyright notices, you must include the
copyright notice for the Library among them, as well as a reference
directing the user to the copy of this License. Also, you must do one
of these things:
a) Accompany the work with the complete corresponding
machine-readable source code for the Library including whatever
changes were used in the work (which must be distributed under
Sections 1 and 2 above); and, if the work is an executable linked
with the Library, with the complete machine-readable "work that
uses the Library", as object code and/or source code, so that the
user can modify the Library and then relink to produce a modified
executable containing the modified Library. (It is understood
that the user who changes the contents of definitions files in the
Library will not necessarily be able to recompile the application
to use the modified definitions.)
b) Use a suitable shared library mechanism for linking with the
Library. A suitable mechanism is one that (1) uses at run time a
copy of the library already present on the user's computer system,
rather than copying library functions into the executable, and (2)
will operate properly with a modified version of the library, if
the user installs one, as long as the modified version is
interface-compatible with the version that the work was made with.
c) Accompany the work with a written offer, valid for at
least three years, to give the same user the materials
specified in Subsection 6a, above, for a charge no more
than the cost of performing this distribution.
d) If distribution of the work is made by offering access to copy
from a designated place, offer equivalent access to copy the above
specified materials from the same place.
e) Verify that the user has already received a copy of these
materials or that you have already sent this user a copy.
For an executable, the required form of the "work that uses the
Library" must include any data and utility programs needed for
reproducing the executable from it. However, as a special exception,
the materials to be distributed need not include anything that is
normally distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on
which the executable runs, unless that component itself accompanies
the executable.
It may happen that this requirement contradicts the license
restrictions of other proprietary libraries that do not normally
accompany the operating system. Such a contradiction means you cannot
use both them and the Library together in an executable that you
distribute.
7. You may place library facilities that are a work based on the
Library side-by-side in a single library together with other library
facilities not covered by this License, and distribute such a combined
library, provided that the separate distribution of the work based on
the Library and of the other library facilities is otherwise
permitted, and provided that you do these two things:
a) Accompany the combined library with a copy of the same work
based on the Library, uncombined with any other library
facilities. This must be distributed under the terms of the
Sections above.
b) Give prominent notice with the combined library of the fact
that part of it is a work based on the Library, and explaining
where to find the accompanying uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute
the Library except as expressly provided under this License. Any
attempt otherwise to copy, modify, sublicense, link with, or
distribute the Library is void, and will automatically terminate your
rights under this License. However, parties who have received copies,
or rights, from you under this License will not have their licenses
terminated so long as such parties remain in full compliance.
9. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Library or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Library (or any work based on the
Library), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Library or works based on it.
10. Each time you redistribute the Library (or any work based on the
Library), the recipient automatically receives a license from the
original licensor to copy, distribute, link with or modify the Library
subject to these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties with
this License.
11. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Library at all. For example, if a patent
license would not permit royalty-free redistribution of the Library by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Library.
If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply,
and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
12. If the distribution and/or use of the Library is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Library under this License may add
an explicit geographical distribution limitation excluding those countries,
so that distribution is permitted only in or among countries not thus
excluded. In such case, this License incorporates the limitation as if
written in the body of this License.
13. The Free Software Foundation may publish revised and/or new
versions of the Lesser General Public License from time to time.
Such new versions will be similar in spirit to the present version,
but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Library
specifies a version number of this License which applies to it and
"any later version", you have the option of following the terms and
conditions either of that version or of any later version published by
the Free Software Foundation. If the Library does not specify a
license version number, you may choose any version ever published by
the Free Software Foundation.
14. If you wish to incorporate parts of the Library into other free
programs whose distribution conditions are incompatible with these,
write to the author to ask for permission. For software which is
copyrighted by the Free Software Foundation, write to the Free
Software Foundation; we sometimes make exceptions for this. Our
decision will be guided by the two goals of preserving the free status
of all derivatives of our free software and of promoting the sharing
and reuse of software generally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Libraries
If you develop a new library, and you want it to be of the greatest
possible use to the public, we recommend making it free software that
everyone can redistribute and change. You can do so by permitting
redistribution under these terms (or, alternatively, under the terms of the
ordinary General Public License).
To apply these terms, attach the following notices to the library. It is
safest to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.
<one line to give the library's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This library is free software; you can redistribute it and/or
modify it under the terms of the GNU Lesser General Public
License as published by the Free Software Foundation; either
version 2.1 of the License, or (at your option) any later version.
This library is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
Lesser General Public License for more details.
You should have received a copy of the GNU Lesser General Public
License along with this library; if not, write to the Free Software
Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Also add information on how to contact you by electronic and paper mail.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the library, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the

Introduction to CMake
---------------------
CMake is a multi-platform build tool that can generate build files for many
different target platforms. See more info at http://www.cmake.org
CMake also allows/recommends you to do "out of source"-builds, that is,
the build files are separated from your sources, so there is no need to
create elaborate clean scripts to get a clean source tree, instead you
simply remove your build directory.
Libwebsockets has been tested to build successfully on the following platforms
with SSL support (both OpenSSL/CyaSSL):
- Windows
- Linux (x86 and ARM)
- OSX
- NetBSD
Building the library and test apps
----------------------------------
The project settings used by CMake to generate the platform specific build
files is called CMakeLists.txt. CMake then uses one of its "Generators" to
output a Visual Studio project or Make file for instance. To see a list of
the available generators for your platform, simply run the "cmake" command.
Note that by default OpenSSL will be linked, if you don't want SSL support
see below on how to toggle compile options.
Building on Unix:
-----------------
1. Install CMake 2.6 or greater: http://cmake.org/cmake/resources/software.html
(Most Unix distributions comes with a packaged version also)
2. Install OpenSSL.
3. Generate the build files (default is Make files):
cd /path/to/src
mkdir build
cd build
cmake ..
(NOTE: The build/ directory can have any name and be located anywhere
on your filesystem, and that the argument ".." given to cmake is simply
the source directory of libwebsockets containing the CMakeLists.txt
project file. All examples in this file assumes you use "..")
NOTE2
A common option you may want to give is to set the install path, same
as --prefix= with autotools. It defaults to /usr/local.
You can do this by, eg
cmake .. -DCMAKE_INSTALL_PREFIX:PATH=/usr
NOTE3
On machines that want libraries in lib64, you can also add the
following to the cmake line
-DLIB_SUFFIX=64
NOTE4
If you are building against a non-distro OpenSSL (eg, in order to get
access to ALPN support only in newer OpenSSL versions) the nice way to
express that in one cmake command is eg,
-DOPENSSL_ROOT_DIR=/usr/local/ssl
4. Finally you can build using the generated Makefile:
make
Quirk of cmake
--------------
When changing cmake options, for some reason the only way to get it to see the
changes sometimes is delete the contents of your build directory and do the
cmake from scratch.
Building on Windows (Visual Studio)
-----------------------------------
1. Install CMake 2.6 or greater: http://cmake.org/cmake/resources/software.html
2. Install OpenSSL binaries. http://www.openssl.org/related/binaries.html
(Preferably in the default location to make it easier for CMake to find them)
3. Generate the Visual studio project by opening the Visual Studio cmd prompt:
cd <path to src>
md build
cd build
cmake -G "Visual Studio 10" ..
(NOTE: There is also a cmake-gui available on Windows if you prefer that)
4. Now you should have a generated Visual Studio Solution in your
<path to src>/build directory, which can be used to build.
Setting compile options
-----------------------
To set compile time flags you can either use one of the CMake gui applications
or do it via command line.
Command line
------------
To list avaialable options (ommit the H if you don't want the help text):
cmake -LH ..
Then to set an option and build (for example turn off SSL support):
cmake -DLWS_WITH_SSL=0 ..
or
cmake -DLWS_WITH_SSL:BOOL=OFF ..
Unix GUI
--------
If you have a curses enabled build you simply type:
(not all packages include this, my debian install does not for example).
ccmake
Windows GUI
-----------
On windows CMake comes with a gui application:
Start -> Programs -> CMake -> CMake (cmake-gui)
CyaSSL replacement for OpenSSL
------------------------------
CyaSSL is a lightweight SSL library targeted at embedded system:
http://www.yassl.com/yaSSL/Products-cyassl.html
It contains a OpenSSL compatability layer which makes it possible to pretty
much link to it instead of OpenSSL, giving a much smaller footprint.
NOTE: cyassl needs to be compiled using the --enable-opensslextra flag for
this to work.
Compiling libwebsockets with CyaSSL
-----------------------------------
cmake .. -DLWS_USE_CYASSL=1 \
-DLWS_CYASSL_INCLUDE_DIRS=/path/to/cyassl \
-DLWS_CYASSL_LIB=/path/to/cyassl/cyassl.a ..
NOTE: On windows use the .lib file extension for LWS_CYASSL_LIB instead.
Cross compiling
---------------
To enable cross compiling libwebsockets using CMake you need to create
a "Toolchain file" that you supply to CMake when generating your build files.
CMake will then use the cross compilers and build paths specified in this file
to look for dependencies and such.
Libwebsockets includes an example toolchain file cross-arm-linux-gnueabihf.cmake
you can use as a starting point.
The commandline to configure for cross with this would look like
cmake .. -DCMAKE_INSTALL_PREFIX:PATH=/usr \
-DCMAKE_TOOLCHAIN_FILE=../cross-arm-linux-gnueabihf.cmake \
-DWITHOUT_EXTENSIONS=1 -DWITH_SSL=0
The example shows how to build with no external cross lib dependencies, you
need to proide the cross libraries otherwise.
NOTE: start from an EMPTY build directory if you had a non-cross build in there
before the settings will be cached and your changes ignored.
Additional information on cross compilation with CMake:
http://www.vtk.org/Wiki/CMake_Cross_Compiling
Memory efficiency
-----------------
Embedded server-only configuration without extensions (ie, no compression
on websocket connections), but with full v13 websocket features and http
server, built on ARM Cortex-A9:
Update at 8dac94d (2013-02-18)
./configure --without-client --without-extensions --disable-debug --without-daemonize

Per-connection [3]: 72 bytes, +1328 during headers

11512 2784 288 4
This shows the impact of the major configuration with/without options at
13ba5bbc633ea962d46d using Ubuntu ARM on a PandaBoard ES.
These are accounting for static allocations from the library elf, there are
additional dynamic allocations via malloc. These are a bit old now but give

Daemonization
-------------
There's a helper api lws_daemonize built by default that does everything you
need to daemonize well, including creating a lock file. If you're making
what's basically a daemon, just call this early in your init to fork to a
headless background process and exit the starting process.
Notice stdout, stderr, stdin are all redirected to /dev/null to enforce your
daemon is headless, so you'll need to sort out alternative logging, by, eg,
syslog.
Maximum number of connections
-----------------------------
The maximum number of connections the library can deal with is decided when
it starts by querying the OS to find out how many file descriptors it is
allowed to open (1024 on Fedora for example). It then allocates arrays that
allow up to that many connections, minus whatever other file descriptors are
in use by the user code.
If you want to restrict that allocation, or increase it, you can use ulimit or
similar to change the avaiable number of file descriptors, and when restarted
libwebsockets will adapt accordingly.
Libwebsockets is singlethreaded
-------------------------------
Directly performing websocket actions from other threads is not allowed.
Aside from the internal data being inconsistent in forked() processes,
the scope of a wsi (struct websocket) can end at any time during service
with the socket closing and the wsi freed.
Websocket write activities should only take place in the
"LWS_CALLBACK_SERVER_WRITEABLE" callback as described below.
Only live connections appear in the user callbacks, so this removes any
possibility of trying to used closed and freed wsis.
If you need to service other socket or file descriptors as well as the
websocket ones, you can combine them together with the websocket ones
in one poll loop, see "External Polling Loop support" below, and
still do it all in one thread / process context.
Only send data when socket writeable
------------------------------------
You should only send data on a websocket connection from the user callback
"LWS_CALLBACK_SERVER_WRITEABLE" (or "LWS_CALLBACK_CLIENT_WRITEABLE" for
clients).
If you want to send something, do not just send it but request a callback
when the socket is writeable using
- libwebsocket_callback_on_writable(context, wsi) for a specific wsi, or
- libwebsocket_callback_on_writable_all_protocol(protocol) for all connections
using that protocol to get a callback when next writeable.
Usually you will get called back immediately next time around the service
loop, but if your peer is slow or temporarily inactive the callback will be
delayed accordingly. Generating what to write and sending it should be done
in the ...WRITEABLE callback.
See the test server code for an example of how to do this.
Do not rely on only your own WRITEABLE requests appearing
---------------------------------------------------------
Libwebsockets may generate additional LWS_CALLBACK_CLIENT_WRITEABLE events
if it met network conditions where it had to buffer your send data internally.
So your code for LWS_CALLBACK_CLIENT_WRITEABLE needs to own the decision
about what to send, it can't assume that just because the writeable callback
came it really is time to send something.
It's quite possible you get an 'extra' writeable callback at any time and
just need to return 0 and wait for the expected callback later.
Closing connections from the user side
--------------------------------------
When you want to close a connection, you do it by returning -1 from a
callback for that connection.
You can provoke a callback by calling libwebsocket_callback_on_writable on
the wsi, then notice in the callback you want to close it and just return -1.
But usually, the decision to close is made in a callback already and returning
-1 is simple.
If the socket knows the connection is dead, because the peer closed or there
was an affirmitive network error like a FIN coming, then libwebsockets will
take care of closing the connection automatically.
If you have a silently dead connection, it's possible to enter a state where
the send pipe on the connection is choked but no ack will ever come, so the
dead connection will never become writeable. To cover that, you can use TCP
keepalives (see later in this document)
Fragmented messages
-------------------
To support fragmented messages you need to check for the final
frame of a message with libwebsocket_is_final_fragment. This
check can be combined with libwebsockets_remaining_packet_payload
to gather the whole contents of a message, eg:
case LWS_CALLBACK_RECEIVE:
{
Client * const client = (Client *)user;
const size_t remaining = libwebsockets_remaining_packet_payload(wsi);
if (!remaining && libwebsocket_is_final_fragment(wsi)) {
if (client->HasFragments()) {
client->AppendMessageFragment(in, len, 0);
in = (void *)client->GetMessage();
len = client->GetMessageLength();
}
client->ProcessMessage((char *)in, len, wsi);
client->ResetMessage();
} else
client->AppendMessageFragment(in, len, remaining);
}
break;
The test app llibwebsockets-test-fraggle sources also show how to
deal with fragmented messages.
Debug Logging
-------------
Also using lws_set_log_level api you may provide a custom callback to actually
emit the log string. By default, this points to an internal emit function
that sends to stderr. Setting it to NULL leaves it as it is instead.
A helper function lwsl_emit_syslog() is exported from the library to simplify
logging to syslog. You still need to use setlogmask, openlog and closelog
in your user code.
The logging apis are made available for user code.
lwsl_err(...)
lwsl_warn(...)
lwsl_notice(...)
lwsl_info(...)
lwsl_debug(...)
The difference between notice and info is that notice will be logged by default
whereas info is ignored by default.
External Polling Loop support
-----------------------------
libwebsockets maintains an internal poll() array for all of its
sockets, but you can instead integrate the sockets into an
external polling array. That's needed if libwebsockets will
cooperate with an existing poll array maintained by another
server.
Four callbacks LWS_CALLBACK_ADD_POLL_FD, LWS_CALLBACK_DEL_POLL_FD,
LWS_CALLBACK_SET_MODE_POLL_FD and LWS_CALLBACK_CLEAR_MODE_POLL_FD
appear in the callback for protocol 0 and allow interface code to
manage socket descriptors in other poll loops.
You can pass all pollfds that need service to libwebsocket_service_fd(), even
if the socket or file does not belong to libwebsockets it is safe.
If libwebsocket handled it, it zeros the pollfd revents field before returning.
So you can let libwebsockets try and if pollfd->revents is nonzero on return,
you know it needs handling by your code.
Using with in c++ apps
----------------------
The library is ready for use by C++ apps. You can get started quickly by
copying the test server
$ cp test-server/test-server.c test.cpp
and building it in C++ like this
$ g++ -DINSTALL_DATADIR=\"/usr/share\" -ocpptest test.cpp -lwebsockets
INSTALL_DATADIR is only needed because the test server uses it as shipped, if
you remove the references to it in your app you don't need to define it on
the g++ line either.
Availability of header information
----------------------------------
From v1.2 of the library onwards, the HTTP header content is free()d as soon
as the websocket connection is established. For websocket servers, you can
copy interesting headers by handling LWS_CALLBACK_FILTER_PROTOCOL_CONNECTION
callback, for clients there's a new callback just for this purpose
LWS_CALLBACK_CLIENT_FILTER_PRE_ESTABLISH.
TCP Keepalive
-------------
It is possible for a connection which is not being used to send to die
silently somewhere between the peer and the side not sending. In this case
by default TCP will just not report anything and you will never get any more
incoming data or sign the link is dead until you try to send.
To deal with getting a notification of that situation, you can choose to
enable TCP keepalives on all libwebsockets sockets, when you create the
context.
To enable keepalive, set the ka_time member of the context creation parameter
struct to a nonzero value (in seconds) at context creation time. You should
also fill ka_probes and ka_interval in that case.
With keepalive enabled, the TCP layer will send control packets that should
stimulate a response from the peer without affecting link traffic. If the
response is not coming, the socket will announce an error at poll() forcing
a close.
Note that BSDs don't support keepalive time / probes / inteveral per-socket
like Linux does. On those systems you can enable keepalive by a nonzero
value in ka_time, but the systemwide kernel settings for the time / probes/
interval are used, regardless of what nonzero value is in ka_time.
Optimizing SSL connections
--------------------------
There's a member ssl_cipher_list in the lws_context_creation_info struct
which allows the user code to restrict the possible cipher selection at
context-creation time.
You might want to look into that to stop the ssl peers selecting a ciher which
is too computationally expensive. To use it, point it to a string like
"RC4-MD5:RC4-SHA:AES128-SHA:AES256-SHA:HIGH:!DSS:!aNULL"
if left NULL, then the "DEFAULT" set of ciphers are all possible to select.
Async nature of client connections
----------------------------------
When you call libwebsocket_client_connect(..) and get a wsi back, it does not
mean your connection is active. It just mean it started trying to connect.
Your client connection is actually active only when you receive
LWS_CALLBACK_CLIENT_ESTABLISHED for it.
There's a 5 second timeout for the connection, and it may give up or die for
other reasons, if any of that happens you'll get a
LWS_CALLBACK_CLIENT_CONNECTION_ERROR callback on protocol 0 instead for the
wsi.
After attempting the connection and getting back a non-NULL wsi you should
loop calling libwebsocket_service() until one of the above callbacks occurs.
As usual, see test-client.c for example code.

Testing server with a browser
-----------------------------
If you run libwebsockets-test-server and point your browser
(eg, Chrome) to
http://127.0.0.1:7681
It will fetch a script in the form of test.html, and then run the
script in there on the browser to open a websocket connection.
Incrementing numbers should appear in the browser display.
By default the test server logs to both stderr and syslog, you can control
what is logged using -d <log level>, see later.
Running test server as a Daemon
-------------------------------
You can use the -D option on the test server to have it fork into the
background and return immediately. In this daemonized mode all stderr is
disabled and logging goes only to syslog, eg, /var/log/messages or similar.
The server maintains a lockfile at /tmp/.lwsts-lock that contains the pid
of the master process, and deletes this file when the master process
terminates.
To stop the daemon, do
kill `cat /tmp/.lwsts-lock`
If it finds a stale lock (the pid mentioned in the file does not exist
any more) it will delete the lock and create a new one during startup.
If the lock is valid, the daemon will exit with a note on stderr that
it was already running.s
Using SSL on the server side
----------------------------
To test it using SSL/WSS, just run the test server with
$ libwebsockets-test-server --ssl
and use the URL
https://127.0.0.1:7681
The connection will be entirely encrypted using some generated
certificates that your browser will not accept, since they are
not signed by any real Certificate Authority. Just accept the
certificates in the browser and the connection will proceed
in first https and then websocket wss, acting exactly the
same.
test-server.c is all that is needed to use libwebsockets for
serving both the script html over http and websockets.
Testing websocket client support
--------------------------------
If you run the test server as described above, you can also
connect to it using the test client as well as a browser.
$ libwebsockets-test-client localhost
will by default connect to the test server on localhost:7681
and print the dumb increment number from the server at the
same time as drawing random circles in the mirror protocol;
if you connect to the test server using a browser at the
same time you will be able to see the circles being drawn.
Testing simple echo
-------------------
You can test against echo.websockets.org as a sanity test like
this (the client connects to port 80 by default):
$ libwebsockets-test-echo --client echo.websocket.org
This echo test is of limited use though because it doesn't
negotiate any protocol. You can run the same test app as a
local server, by default on localhost:7681
$ libwebsockets-test-echo
and do the echo test against the local echo server
$ libwebsockets-test-echo --client localhost --port 7681
If you add the --ssl switch to both the client and server, you can also test
with an encrypted link.
Testing SSL on the client side
------------------------------
To test SSL/WSS client action, just run the client test with
$ libwebsockets-test-client localhost --ssl
By default the client test applet is set to accept selfsigned
certificates used by the test server, this is indicated by the
use_ssl var being set to 2. Set it to 1 to reject any server
certificate that it doesn't have a trusted CA cert for.
Using the websocket ping utility
--------------------------------
libwebsockets-test-ping connects as a client to a remote
websocket server using 04 protocol and pings it like the
normal unix ping utility.
$ libwebsockets-test-ping localhost
handshake OK for protocol lws-mirror-protocol
Websocket PING localhost.localdomain (127.0.0.1) 64 bytes of data.
64 bytes from localhost: req=1 time=0.1ms
64 bytes from localhost: req=2 time=0.1ms
64 bytes from localhost: req=3 time=0.1ms
64 bytes from localhost: req=4 time=0.2ms
64 bytes from localhost: req=5 time=0.1ms
64 bytes from localhost: req=6 time=0.2ms
64 bytes from localhost: req=7 time=0.2ms
64 bytes from localhost: req=8 time=0.1ms
^C
--- localhost.localdomain websocket ping statistics ---
8 packets transmitted, 8 received, 0% packet loss, time 7458ms
rtt min/avg/max = 0.110/0.185/0.218 ms
$
By default it sends 64 byte payload packets using the 04
PING packet opcode type. You can change the payload size
using the -s= flag, up to a maximum of 125 mandated by the
04 standard.
Using the lws-mirror protocol that is provided by the test
server, libwebsockets-test-ping can also use larger payload
sizes up to 4096 is BINARY packets; lws-mirror will copy
them back to the client and they appear as a PONG. Use the
-m flag to select this operation.
The default interval between pings is 1s, you can use the -i=
flag to set this, including fractions like -i=0.01 for 10ms
interval.
Before you can even use the PING opcode that is part of the
standard, you must complete a handshake with a specified
protocol. By default lws-mirror-protocol is used which is
supported by the test server. But if you are using it on
another server, you can specify the protcol to handshake with
by --protocol=protocolname
Fraggle test app
----------------
By default it runs in server mode
$ libwebsockets-test-fraggle
libwebsockets test fraggle

You need to run a second session in client mode, you have to
give the -c switch and the server address at least:
$ libwebsockets-test-fraggle -c localhost

...
The fraggle test sends a random number up to 1024 fragmented websocket frames
each of a random size between 1 and 2001 bytes in a single message, then sends
a checksum and starts sending a new randomly sized and fragmented message.
The fraggle test client receives the same message fragments and computes the
same checksum using websocket framing to see when the message has ended. It
then accepts the server checksum message and compares that to its checksum.
proxy support
-------------
The http_proxy environment variable is respected by the client
connection code for both ws:// and wss://. It doesn't support
authentication.
You use it like this
export http_proxy=myproxy.com:3128
libwebsockets-test-client someserver.com
debug logging
-------------
By default logging of severity "notice", "warn" or "err" is enabled to stderr.
Again by default other logging is comiled in but disabled from printing.
If you want to eliminate the debug logging below notice in severity, use the
--disable-debug configure option to have it removed from the code by the
preprocesser.
If you want to see more detailed debug logs, you can control a bitfield to
select which logs types may print using the lws_set_log_level() api, in the
test apps you can use -d <number> to control this. The types of logging
available are (OR together the numbers to select multiple)
1 ERR
2 WARN
4 NOTICE
8 INFO
16 DEBUG
32 PARSER
64 HEADER
128 EXTENSION
256 CLIENT
512 LATENCY
Websocket version supported
---------------------------
The final IETF standard is supported for both client and server, protocol
version 13.
Latency Tracking
----------------
Since libwebsockets runs using poll() and a single threaded approach, any
unexpected latency coming from system calls would be bad news. There's now
a latency tracking scheme that can be built in with --with-latency at
configure-time, logging the time taken for system calls to complete and if
the whole action did complete that time or was deferred.
You can see the detailed data by enabling logging level 512 (eg, -d 519 on
the test server to see that and the usual logs), however even without that
the "worst" latency is kept and reported to the logs with NOTICE severity
when the context is destroyed.
Some care is needed interpreting them, if the action completed the first figure
(in us) is the time taken for the whole action, which may have retried through
the poll loop many times and will depend on network roundtrip times. High
figures here don't indicate a problem. The figure in us reported after "lat"
in the logging is the time taken by this particular attempt. High figures
here may indicate a problem, or if you system is loaded with another app at
that time, such as the browser, it may simply indicate the OS gave preferential
treatment to the other app during that call.

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

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

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

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

* This function creates the listening socket (if serving) and takes care
* of all initialization in one step.
*
* After initialization, it returns a struct libwebsocket_context * that
* represents this server. After calling, user code needs to take care
* of calling libwebsocket_service() with the context pointer to get the
* server's sockets serviced. This must be done in the same process
* context as the initialization call.
*
* The protocol callback functions are called for a handful of events
* including http requests coming in, websocket connections becoming
* established, and data arriving; it's also called periodically to allow
* async transmission.
*
* HTTP requests are sent always to the FIRST protocol in @protocol, since
* at that time websocket protocol has not been negotiated. Other
* protocols after the first one never see any HTTP callack activity.
*
* The server created is a simple http server by default; part of the
* websocket standard is upgrading this http connection to a websocket one.
*
* This allows the same server to provide files like scripts and favicon /
* images or whatever over http and dynamic data over websockets all in
* one place; they're all handled in the user callback.

* @len: Count of the data bytes in the payload starting from buf
* @protocol: Use LWS_WRITE_HTTP to reply to an http connection, and one

* call blocks your thread until it needs to take care of something and
* would call it with a large nonzero timeout. Your loop then takes no
* CPU while there is nothing happening.
*
* If you are calling it in a single-threaded app, you don't want it to
