Description:

LuaSocket 3.0rc1 shipped with a bug when using socket read timeouts; this was fixed in the following commit:

https://github.com/diegonehab/luasocket/commit/396e9e5

Until a new version of LuaSocket is released, would it be possible to apply this patch to the Arch package?

Additional info:
LuaSocket v3.0rc1

Steps to reproduce:

1) Run the following Perl oneliner to create a dummy server listening on port 9000, which writes the numbers 1-100 to a client, pausing for 100ms before each write:

perl -MTime::HiRes=usleep -MIO::Socket -E 'my $server = IO::Socket::INET->new(Proto => "tcp", Listen => 5, LocalAddr => "localhost", LocalPort => 9000, ReuseAddr => 1) or die "cant create socket: $!"; my $client = $server->accept; for(1..100) { usleep 100_000; $client->say($_); } $client->close; $server->close;'

2) Run the attached Lua script, which connects to the server on port 9000 and has a read timeout of 1000ms, but fails with a timeout somewhere during the 100 reads. (I ran the script with both Lua 5.1 and 5.2)

3) If you build LuaSocket from Git with that commit, install it to a temporary directory, and point LUA_PATH and LUA_CPATH to that temporary directory, the timeout does not occur.
