   Changelog for the c-ares project
 
+* August 3 2006
+
+- Ravi Pratap fixed ares_getsock() to actually return the proper bitmap and
+  not always zero!
+
+Version 1.3.1 (June 24, 2006)
+
+* July 23, 2006
+
+- Gisle Vanem added getopt() to the ahost program. Currently accepts
+  only [-t {a|aaaa}] to specify address family in ares_gethostbyname().
+
+* June 19, 2006
+
+- (wahern) Removed "big endian" DNS section and RR data integer parser
+  macros from ares_dns.h, which break c-ares on my Sparc64. Bit-wise
+  operations in C operate on logical values. And in any event the octets are
+  already in big-endian (aka network) byte order so they're being reversed
+  (thus the source of the breakage).
+
+* June 18, 2006
+
+- William Ahern handles EAGAIN/EWOULDBLOCK errors in most of the I/O calls
+  from area_process.c.
+
+  TODO: Handle one last EAGAIN for a UDP socket send(2) in
+  ares__send_query().
+

+CURLMcode curl_multi_assign(CURLM *multi_handle, curl_socket_t sockfd,
+                            void *sockptr);
+.SH DESCRIPTION
+This function assigns an association in the multi handle between the given
+socket and a private pointer of the application. This is (only) useful for
+\fIcurl_multi_socket(3)\fP uses.
+
+When set, the \fIsockptr\fP pointer will be passed to all future socket
+callbacks for the specific \fIsockfd\fP socket.
+
+If the given \fIsockfd\fP isn't already in use by libcurl, this function will
+return an error.
+
+libcurl only keeps one single pointer associated with a socket, so calling
+this function several times for the same socket will make the last set pointer
+get used.
+
+The idea here being that this association (socket to private pointer) is
+something that just about every application that uses this API will need and
+then libcurl can just as well do it since it already has an internal hash
+table lookup for this.
+.SH "RETURN VALUE"
+The standard CURLMcode for multi interface error codes.

+In a typical application you allocate a struct or at least use some kind of
+semi-dynamic data for each socket that we must wait for action on when using
+the \fIcurl_multi_socket(3)\fP approach.
+
+When our socket-callback get called by libcurl and we get to know about yet
+another socket to wait for, we can use \fIcurl_multi_assign(3)\fP to point out
+the particular data so that when we get updates about this same socket again,
+we don't have to find the struct associated with this socket by ourselves.

+April 11, 2006
+
+ While sitting staring on my screen trying to write up a *nice* sample script
+ using libevent, it strikes me that since libevent is pretty much based around
+ its structs that you setup for each event/file descriptor, my application
+ wants to figure out the correct struct that is associted with the file
+ descriptor that libcurl provides in the socket callback.
+
+ This feels like an operation most applications will need when using the
+ multi_socket API, so it feels like I should better try to figure out a decent
+ way to offer this basic functionality already in libcurl - and the fact that
+ we already have the file descriptors in a hash we can probably just as well
+ extend it somewhat and store some custom pointers as well.
+
+ We need to offer the app a way to set a private pointer to be associated with
+ the particular file descriptor, and then be able to provide that pointer on
+ subsequent callback calls.
+
+---------------------------------------------------------------------------
+
+April 20, 2006
+
+ I was wrong when I previously claimed we could have more than one easy handle
+ using the same socket. I've cleaned up and simplified code now to adjust to
+ this.
+
+---------------------------------------------------------------------------
+
+July 9, 2006
+
+ TODO: We need to alter how we use c-ares for getting info about its sockets,
+ as c-ares now provides a callback approach very similar to how libcurl is
+ about to work.
+
+ I'm adding a function called curl_multi_assign() that will set a private
+ pointer added to the internal libcurl hash table for the particular socket
+ passed in to this function:
+
+ CURLMcode curl_multi_assign(CURLM *multi_handle,
+                             curl_socket_t sockfd,
+                             void *sockp);
+
+ 'sockp' being a custom pointer set by the application to be associated with
+ this socket. The socket has to be already existing and in-use by libcurl,
+ like having already called the callback telling about its existance.
+
+ The set hashp pointer will then be passed on to the callback in upcoming
+ calls when this same socket is used (in the brand new 'socketp' argument).
+
+---------------------------------------------------------------------------
+
+July 30, 2006
+
+ Shockingly stupid (of me not having realized this before), but we really need
+ to add a 'running_handles' argument to the curl_multi_socket() and
+ curl_multi_socket_all() prototypes so that the caller can get to know when
+ all the transfers are actually done!
