165d30e31a Fix compilation of rate-limiting code on win32. 2009-12-30 14:29:56 -05:00
Jardel Weyrich
d0939d2b97 Introduced evutil_make_socket_closeonexec() to preserve fd flags for F_SETFD. 
Use this to eliminate the various macros that called F_SETFD throughout
the code.

4df7dbcbdf Adjusted fcntl() retval comparison on evutil_make_socket_nonblocking(). 
Apparently, a successful return value on F_SETFL is "anything but
-1".

f070a4aed2 Do the proper hack for the (Open)BSD getaddrinfo quirk. 
From evutil.c:

   Some older BSDs (like OpenBSD up to 4.6) used to believe that
   giving a numeric port without giving an ai_socktype was verboten.
   We test for this so we can apply an appropriate workaround.  If it
   turns out that the bug is present, then:

    - If nodename==NULL and servname is numeric, we build an answer
      ourselves using evutil_getaddrinfo_common().

    - If nodename!=NULL and servname is numeric, then we set
      servname=NULL when calling getaddrinfo, and post-process the
      result to set the ports on it.

   We test for this bug at runtime, since otherwise we can't have the
   same binary run on multiple BSD versions.

86f5742015 Add two implementations of getaddrinfo: one blocking and one nonblocking. 
The entry points are evutil_getaddrinfo and evdns_getaddrinfo respectively.
There are fairly extensive unit tests.

I believe this code conforms to RFC3493 pretty closely, but there are
probably more issues.  It should get tested on more platforms.

This code means we can dump the well-intentioned but weirdly-implemented
bufferevent_evdns and evutil_resolve code.

that do not define issetugid.

0b9eb1bffb Add a bufferevent function to resolve a name then connect to it. 
This function, bufferevent_socket_connect_hostname() can either use
evdns to do the resolve, or use a new function (evutil_resolve) that
uses getaddrinfo or gethostbyname, like http.c does now.

This function is meant to eventually replace the hostname resolution mess in
http.c.

709c21c48c Bufferevent support for openssl. 
This code adds a new Bufferevent type that is only compiled when the
openssl library is present.  It supports using an SSL object and an
event alert mechanism, which can either be an fd or an underlying
bufferevent.

There is still more work to do: the unit tests are incomplete, and we
need to support flush and shutdown much better.  Sometimes events are
generated needlessly: this will hose performance.

There's a new encrypting proxy in sample/le-proxy.c.

This code has only been tested on OSX, and nowhere else.

cd731b77d7 Do not use ctypes functions in cases when we need the "net" locale. 
This patch adds a new set of EVUTIL_IS* functions to replace use of
the ctypes is* functions in all cases where we care about characters'
interpretations in net ascii rather than in the locale.  For example,
when we're working with DNS hostnames, we don't want to do the 0x20
hack on non-ascii characters, even if the host thinks they should be
isalpha.
