a1d5983991 use macros ERRNO, SET_ERRNO(), SOCKERRNO and SET_SOCKERRNO() for errno handling 2007-02-16 18:19:35 +00:00
Daniel Stenberg
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.

ebee2e323d - David McCreedy fixed a bad call to getsockname() that wrongly used a size_t 
variable to point to when it should be a socklen_t.

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.

2fbf94b0f3 Added CURLOPT_LOCALPORT and CURLOPT_LOCALPORTRANGE to libcurl. Set with the 
curl tool with --local-port. Plain and simply set the range of ports to bind
the local end of connections to. Implemented on to popular demand.

Not extensively tested. Please let me know how it works.

be1cece69b - Larry Campbell added CURLINFO_OS_ERRNO to curl_easy_getinfo() that allows an 
app to retrieve the errno variable after a (connect) failure. It will make
  sense to provide this for more failures in a more generic way, but let's
  start like this.

4b9f8e766d Made host name and proxy name get stored in a 'struct hostname' and set 
all things up to work with encoded host names internally, as well as keeping
'display names' to show in debug messages. IDN resolves work for me now using
ipv6, ipv4 and ares resolving. Even cookies on IDN sites seem to do right.

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.
