These are options needed for real-world multicasting.
Implementation notes:
- POSIX only.
- IPv4 only (IPv6 multicast is a tricky beast).
- Didn't update tests, because it can't effectively be demonstrated on
localhost only.
The windows socket api uses handles, not fds. Libev caches the handle
associated with an fd, and uses this handle when updating the (also cached)
handle set that goes into select(). When an fd is closed and subsequently
re-used before the event loop returns to libev, libev fails to detect
properly that the handle changed. And even if it does, the cached handle of
the closed socket is overwritten by the new handle, so by the time libev
tries to update the select fdset it has forgotten which handle to remove
from it. This is solved by a simple hook ev_fd_closed that makes it clear
its caches before the fd is re-used.
AF_UNIX sockets can have a pathname, be unnamed, or abstract (Linux
only). If an unnamed socket is returned by getsockname, getpeername, or
accept, sun_path should not be inspected.
By default windows creates sockets with the WSA_FLAG_OVERLAPPED flag set.
Because child processes don't expect to have overlapped stdio (it never happens)
it won't work with them.
Set the stage for making the builtin modules more dynamic.
Note: this only converts crypto and net, I will add more extensions in a
later commit.
* node.h: Add utility macro for converting macro values to strings.
* node.h: Include the actual module name inside the module structure, not
just the file it was built from.
* node.h: New Macro, NODE_MODULE_DECL, for declaring an external reference
to a module structure.
* node_extensions.cc: New File, implements get_builtin_module, which
iterates over the module structures that are compiled into node.
* node.cc(node::Binding): Use the new module lookup function to find
modules.
* node_{net,crypto}.c: Add NODE_MODULEs to generate the module structure.
C-Ares doesn't go through the Name Service Switch (NSS) and thus can't
resolve certain classes of names. Generally this doesn't matter and the
whole idea of NSS is rather annoying. Nevertheless until C-Ares gets better
support, adding this hack to go through getaddrinfo() for .local domain look
up.
This reverts commit 9926dacd14.
- Adds new dgram module, for all data-gram type transports
- Supports both UDP client and servers
- Supports Unix Daemon sockets in DGRAM mode too (think syslog)
- Uses a shared Buffer and slices that as needed to be reasonably
performant.
- One supplied test program so far, test-dgram-pingpong
- Passes test cases on osx 10.6 and ubuntu 9.10u
