What's New
There is no big change for the 2.0 (final) release. It is
basically a bug fix release. The main improvement is in the
non-blocking support.
* New: sample module dispatch.lua implements a coroutine
based dispatcher;
* New: sample check-links.lua works both in blocking and
non-blocking mode using coroutines (using the new
dispatcher);
* New: sample forward.lua implements a coroutine based
forward server (using the new dispatcher);
* Improved: tcp:send(data, i, j) to return (i+sent-1). This
is great for non-blocking I/O, but might break some code;
* Improved: HTTP, SMTP, and FTP functions to accept a new
field create that overrides the function used to create
socket objects;
* Improved: smtp.message now supports multipart/alternative
(for the HTML messages we all love so much);
* Fixed: smtp.send was hanging on errors returned by LTN12
sources;
* Fixed: url.absolute() to work when base_url is in parsed
form;
* Fixed: http.request() not to redirect when the location
header is empty (naughty servers...);
* Fixed: tcp{client}:shutdown() to check for class instead
of group;
* Fixed: The manual to stop using socket.try() in place of
assert(), since it can't;
* Improved: Got rid of package.loaded.base = _G kludge;
* Fixed: Parts of the manual referred to require("http")
instead of require("socket.http");
* Improved: Socket and MIME binaries are called 'core' each
inside their directory (ex. "socket/core.dll"). The 'l'
prefix was just a bad idea;
* Improved: Using bundles in Mac OS X, instead of dylibs;
* Fixed: luasocket.h to export luaopen_socket_core;
* Fixed: udp:setpeername() so you can "disconnect" an UDP
socket;
* Fixed: A weird bug in HTTP support that caused some
requests to fail (Florian Berger);
* Fixed: Bug in socket.select() that caused sockets with
descriptor 0 to be ignored (Renato Maia);
* Fixed: "Bug" that caused dns.toip() to crash under uLinux
(William Trenker);
* Fixed: "Bug" that caused gethostbyname to crash under VMS
(Renato Maia);
* Fixed: tcp:send("") to return 0 bytes sent (Alexander
Marinov);
* Improved: socket.DEBUG and socket.VERSION became
socket._DEBUGs and socket._VERSION for uniformity with other
libraries;
* Improved: socket.select now works on empty sets on Windows.
