<h2 id=new>What's New</h2>
|
||||
|
||||
|
||||
<p>
|
||||
<em>Everything</em> is new! Many changes for 2.0 happened in the C layer,
|
||||
which has been almost completely rewritten. The code has been ported to
|
||||
Lua 5.0 and greatly improved. There have also been some API changes
|
||||
that made the interface simpler and more consistent. Here are some of
|
||||
the changes that made it into version 2.0:
|
||||
Changes in the 2.0-beta2 were mostly bug-fixes.
|
||||
</p>
|
||||
|
||||
<ul>
|
||||
<li> Major C code rewrite. Code is modular and extensible. Hopefully, other
|
||||
developers will be motivated to provide code for SSL, local domain
|
||||
sockets, file descriptors, pipes (on Unix) and named pipes etc;
|
||||
|
||||
<li> Everything that is exported by the library is exported inside
|
||||
namespaces. These should be obtained with calls to the
|
||||
<tt>require</tt> function;
|
||||
|
||||
<li> Functions such as
|
||||
send/receive/timeout/close etc do not exist anymore as stand-alone
|
||||
functions. They are now only available as methods of the appropriate
|
||||
objects;
|
||||
|
||||
<li> All functions return a non-nil value as first return value if successful.
|
||||
All functions return <b><tt>nil</tt></b> followed by error message
|
||||
in case of error. This made the library much easier to use;
|
||||
|
||||
<li> Greatly reduced the number of times the C select is called
|
||||
during data transfers, by calling only on failure. This might
|
||||
improve a lot the maximum throughput;
|
||||
|
||||
<li> TCP has been changed to become more uniform. It's possible to first
|
||||
create a TCP object,
|
||||
then connect or bind if needed, and finally use I/O functions.
|
||||
<tt>socket.connect</tt> and <tt>socket.bind</tt> functions are still
|
||||
provided for simplicity;
|
||||
|
||||
<li> This allows for setting a timeout value before connecting;
|
||||
|
||||
<li> And also allows binding to a local address before connecting;
|
||||
|
||||
<li> New <tt>socket.dns.gethostname</tt> function and <tt>shutdown</tt>
|
||||
method;
|
||||
|
||||
<li> Better error messages and parameter checking;
|
||||
|
||||
<li> Should be interrupt safe;
|
||||
|
||||
<li> UDP connected sockets can break association with peer by calling
|
||||
<tt>setpeername</tt> with address '<tt>*</tt>';
|
||||
|
||||
<li> Sets returned by <tt>socket.select</tt> are associative;
|
||||
|
||||
<li> Select checks if sockets have buffered data and returns immediately;
|
||||
|
||||
<li> <tt>socket.sleep</tt> and <tt>socket.gettime</tt> are now part of the
|
||||
library and are supported. They used to be available only when
|
||||
LUASOCKET_DEBUG was defined, but it turns out they might be useful for
|
||||
applications;
|
||||
|
||||
<li> <tt>socket.try</tt> and <tt>socket.protect</tt> provide a simple
|
||||
interface to exceptions that proved very in the implementation of
|
||||
high-level modules;
|
||||
|
||||
<li> Socket options interface has been improved. TCP objects also
|
||||
support socket options and many new options were added.
|
||||
|
||||
</ul>
|
||||
|
||||
<p>
|
||||
Lots of changes in the Lua modules, too!
|
||||
</p>
|
||||
|
||||
<ul>
|
||||
<li> Every module loads only the modules that it needs. There is no waste
|
||||
of memory. LuaSocket core takes only 20k of memory;
|
||||
|
||||
<li> New MIME and LTN12 modules make all other modules much more powerful;
|
||||
|
||||
<li> Support for multipart messages in the SMTP module;
|
||||
|
||||
<li> The old callback mechanism of FTP and HTTP has been replaced with LTN12 sources and sinks, with advantage;
|
||||
|
||||
<li> Common implementation for low-level FTP and SMTP;
|
||||
|
||||
<li> FTP, HTTP, and SMTP are implemented in multiple levels in such a way
|
||||
that users will have no problems extending the functionality to satisfy
|
||||
personal needs;
|
||||
|
||||
<li> SMTP knows how to perform LOGIN and PLAIN authentication.
|
||||
|
||||
<li> Fixed silly last minute bugs in HTTP/SMTP that prevented them from
|
||||
running;
|
||||
<li> <tt>usocket.c</tt>/<tt>wsocket.c</tt> look nicer thanks to Mike;
|
||||
<li> UDP has a reasonable maximum datagram size;
|
||||
<li> <tt>Receive</tt> accepts the prefix optional argument (good for
|
||||
non-blocking);
|
||||
<li> <b><tt>Send</tt> doesn't support multiple arguments anymore</b>;
|
||||
<li> Instead, <tt>send</tt> allows the selection of the substring
|
||||
to be sent (good for non-blocking);
|
||||
<li> Fixed bug that caused select return tables not to be associative
|
||||
on windows;
|
||||
<li> Should compiles with g++;
|
||||
<li> New sample unix domain support;
|
||||
<li> New sample LPD support;
|
||||
<li> Comprehensive error messages;
|
||||
<li> New <tt>getstats</tt> and <tt>setstats</tt> methods to help throttling;
|
||||
<li> <tt>Listen</tt> defaults to 32 backlog;
|
||||
<li> SMTP/FTP/HTTP fail gracefully;
|
||||
<li> <tt>accept</tt>/<tt>connect</tt>/<tt>select</tt> interrupt safe
|
||||
<li> Fixed bug that didn't set accepted sockets as non-blocking
|
||||
<li> <b>New timming functions <tt>sleep</tt> and <tt>gettime</tt> have
|
||||
higher resolution and no wrap around problems</b>;
|
||||
<li> Bug fixes in the manual;
|
||||
<li> Fixed bug of missing cast in <tt>getfd</tt>.
