930a45e7a9 - Added CURLINFO_PRIMARY_IP as a new information retrievable with 
curl_easy_getinfo. It returns a pointer to a string with the most recently
  used IP address. Modified test case 500 to also verify this feature. The
  implementing of this feature was sponsored by Lenny Rachitsky at NeuStar.

514592b892 - Introducing curl_easy_send() and curl_easy_recv(). They can be used to send 
and receive data over a connection previously setup with curl_easy_perform()
  and its CURLOPT_CONNECT_ONLY option. The sendrecv.c example was added to
  show how they can be used.

b84b71f524 - Jean-Francois Bertrand reported a libcurl crash with CURLOPT_TCP_NODELAY 
since libcurl used getprotobyname() and that isn't thread-safe. We now
  switched to use IPPROTO_TCP unconditionally, but perhaps the proper fix is
  to detect the thread-safe version of the function and use that.

1b701c746f - Refactored a lot of timeout code into a few functions in an attempt to make 
them all use the same (hopefully correct) logic to make it less error-prone
  and easier to introduce library-wide where it should be used.

67d94514b0 Kim Rinnewitz reported that --local-port didn't work with TFTP transfers. 
This happened because the tftp code always uncondionally did a bind()
without caring if one already had been done and then it failed. I wrote a
test case (1009) to verify this, but it is a bit error-prone since it will
have to pick a fixed local port number and since the tests are run on so
many different hosts in different situations I add it in disabled state.

ce1cfcb7a6 Alexey Pesternikov introduced CURLOPT_OPENSOCKETFUNCTION and 
CURLOPT_OPENSOCKETDATA to set a callback that allows an application to replace
the socket() call used by libcurl. It basically allows the app to change
address, protocol or whatever of the socket. (I also did some whitespace
indent/cleanups in lib/url.c which kind of hides some of these changes, sorry
for mixing those in.)

9f44a95522 Renamed several libcurl error codes and options to make them more general 
and allow reuse by multiple protocols. Several unused error codes were
removed.  In all cases, macros were added to preserve source (and binary)
compatibility with the old names.  These macros are subject to removal at
a future date, but probably not before 2009.  An application can be
tested to see if it is using any obsolete code by compiling it with the
CURL_NO_OLDIES macro defined.

Documented some newer error codes in libcurl-error(3)

188b08ca55 Patrick Monnerat's cleanup fix after my alloc-strings commit 2007-08-02 14:42:16 +00:00
Daniel Stenberg
50c10aa5bf Patrick Monnerat and I modified libcurl so that now it *copies* all strings 
passed to it with curl_easy_setopt()! Previously it has always just refered
to the data, forcing the user to keep the data around until libcurl is done
with it. That is now history and libcurl will instead clone the given
strings and keep private copies.

76627b322e - Robert Iakobashvil added curl_multi_socket_action() to libcurl, which is a 
function that deprecates the curl_multi_socket() function. Using the new
  function the application tell libcurl what action that was found in the
  socket that it passes in. This gives a significant performance boost as it
  allows libcurl to avoid a call to poll()/select() for every call to
  curl_multi_socket*().

91386937ff - Michael Wallner provided a patch that adds support for CURLOPT_TIMEOUT_MS 
and CURLOPT_CONNECTTIMEOUT_MS that, as their names should hint, do the
  timeouts with millisecond resolution instead. The only restriction to that
  is the alarm() (sometimes) used to abort name resolves as that uses full
  seconds. I fixed the FTP response timeout part of the patch.

  Internally we now count and keep the timeouts in milliseconds but it also
  means we multiply set timeouts with 1000. The effect of this is that no
  timeout can be set to more than 2^31 milliseconds (on 32 bit systems), which
  equals 24.86 days.  We probably couldn't before either since the code did
  *1000 on the timeout values on several places already.

e85e30546c Roland Blom filed bug report #1481217 
(http://curl.haxx.se/bug/view.cgi?id=1481217), with follow-ups by Michele Bini
and David Byron. libcurl previously wrongly used GetLastError() on windows to
get error details after socket-related function calls, when it really should
use WSAGetLastError() instead.

When changing to this, the former function Curl_ourerrno() is now instead
called Curl_sockerrno() as it is necessary to only use it to get errno from
socket-related functions as otherwise it won't work as intended on Windows.

43bb20461f Peter Sylvester found a flaw in the connect code for ipv6-enabled hosts. 
I guess it seldomly happens on linux and that's why it wasn't found before.
He used Solaris to notice it.

I took the opportunity to rewrite the Curl_connecthost() slightly to feature
less duplicate code in the two different versions (ipv4/ipv6).

a9af971c59 Avoid doing getsockopt() on Windows to verify connects. It seems that this 
hogs Windows machines when libcurl is being used multi-threaded (with > ~50
threads). Andrew Fuller helped us verify and test this.

According to a MSDN web page on connect(), it returns 0 when the connect
is done and thus we don't need the getsockopt() call anyway on Windows.

2cff251863 Curl_resolv() now returns a different struct, and it contains a reference 
counter so that the caller needs to decrease that counter when done with

is decreased before a handle is closed etc.

8927ddec16 In order to not get problems with DNS cache pruning, we no longer store 
any name resolved data in any curl handle struct. That way, we won't mind
if the cache entries are pruned for the next time we need them. We'll just
resolve them again instead.

This changes the Curl_resolv() proto. It modifies the SessionHandle struct
but perhaps most importantly, it'll make the internals somewhat dependent
on the DNS cache not being disabled as that will cripple operations somewhat.
Especially for persistant connections.
