Some systems like Mac OS X 10.5 (and lower) do not have EAI_OVERFLOW and
AI_NUMERICSERV defined.
These variables are used to avoid a potentially slow name resolution
for the hostname (which will always be an ip address)
and for service name (which will always be an actual port number).
The code might be slower, but it should still work.
Closes: #242
This is a difficult tradeoff to measure. I think large
datagrams won't be used very frequently. So it is better to
not lock a large buffer to each socket object and instead
allocate and deallocate for each operation receiving a
datagram larger than UDP_DATAGRAMSIZE.
Documentation says "dontroute", "broadcast", "reuseaddr", and
"reuseport" are supported as arguments to getoption, however their
implementations were missing.
inet_pton was copying the entire sockaddr_in struct,
rather than just the sin_addr field...
I am a bit unsure about the UDP fix, because it may affect
TCP as well. On UDP sockets, when a sendto fails, the next
receive/receivefrom fails with CONNRESET. I changed
sock_recv/sock_recvfrom in wsocket.c to skip the CONNRESET
from the recv/recvfrom, hoping that if the socket is TCP,
sock_waitfd will get the CONNRESET again. The tests pass,
but this should be tested more thoroughly.
There seems to be a curious difference between MacOS and
Linux and I am not sure if this is documented. When you
break a "connection" on Mac OS, you only eliminate the peer
association, but the local address remains bound. On Linux,
breaking a "connection" eliminates the binding to the local
address. Have you guys ever come accross this?
Another irritating difference is that connect() returns the
error EAFNOSUPPORT on Mac OS. I am going to ignore all
errors when the reason for calling connect() is simply to
break the "connection".
- Added IPv6 support to getsockname
- Simplified getpeername implementation
- Added family to return of getsockname and getpeername
and added modification to the manual to describe
Documented headers.lua
Update copyright date everywhere
Remove RCSID from files
Move version back to 2.1 rather than 2.1.1
Fixed url package to support ipv6 hosts
Changed "domain" to "family" in tcp and udp structures
Implemented getfamily methods
Conflicts in options.c were just due to independent small functions
being close to each other.
unix.c in mwild was broken, it wasn't using LUASOCKET_API.
serial.c needed luaL_reg renamed, and to use LUASOCKET_API.
makefile didn't respect standard DESTDIR and prefix makefile
variables, and didn't allow LUAV variable to select lua version to build
against.
I've tested the top-level install-both target builds and installs
against both lua5.1 and lua5.2, but not done further testing.
Conflicts:

Implemented new distribution scheme.
Select is now purely C.
HTTP reimplemented seems faster dunno why.
LTN12 functions that coroutines fail gracefully.
