aff5408633 made Curl_read_plain() return an 'int' instead of CURLcode since it actually 
returns -1 in EAGAIN cases and that's not valid CURLcode
 2008-09-29 11:13:37 +00:00

391e8afd1f - Made the SOCKS code use the new Curl_read_plain() function to fix the bug 
Markus Moeller reported: http://curl.haxx.se/mail/archive-2008-09/0016.html

- recv() errors other than those equal to EAGAIN now cause proper
  CURLE_RECV_ERROR to get returned. This made test case 160 fail so I've now
  disabled it until we can figure out another way to exercise that logic.

4c9768565e - Introducing CURLOPT_CERTINFO and the corresponding CURLINFO_CERTINFO. By 
enabling this feature with CURLOPT_CERTINFO for a request using SSL (HTTPS
  or FTPS), libcurl will gather lots of server certificate info and that info
  can then get extracted by a client after the request has completed with
  curl_easy_getinfo()'s CURLINFO_CERTINFO option. Linus Nielsen Feltzing
  helped me test and smoothen out this feature.

  Unfortunately, this feature currently only works with libcurl built to use
  OpenSSL.

  This feature was sponsored by networking4all.com - thanks!

422fd933f5 - Hans-Jurgen May pointed out that trying SCP or SFTP over a SOCKS proxy 
crashed libcurl. This is now addressed by making sure we use "plain send"
  internally when doing the socks handshake instead of the Curl_write()
  function which is designed to use the "target" protocol. That's then SCP or
  SFTP in this case. I also took the opportunity and cleaned up some ssh-
  related #ifdefs in the code for readability.

e2b82b4325 - Make Curl_write and it's callees accept a const pointer, in preparation

53a549000c - Based on initial work done by Gautam Kachroo to address a bug, we now keep 
better control at the exact state of the connection's SSL status so that we
  know exactly when it has completed the SSL negotiation or not so that there
  won't be accidental re-uses of connections that are wrongly believed to be
  in SSL-completed-negotiate state.

that it is bad anyway. Starting now, removing a handle that is in used in a

0fb5a65a58 - David McCreedy provided libcurl changes for doing HTTP communication on 
non-ASCII platforms. It does add some complexity, most notably with more
  #ifdefs, but I want to see this supported added and I can't see how we can
  add it without the extra stuff added.

d8ff0336a5 - Matt Witherspoon fixed the flaw which made libcurl 7.16.0 always store 
downloaded data in two buffers, just to be able to deal with a special HTTP
  pipelining case. That is now only activated for pipelined transfers. In
  Matt's case, it showed as a considerable performance difference,

5fd096da8d Stefan Krause pointed out a compiler warning with a picky MSCV compiler when 
passing a curl_off_t argument to the Curl_read_rewind() function which takes
an size_t argument. Curl_read_rewind() also had debug code left in it and it
was put in a different source file with no good reason when only used from
one single spot.

a similar cleanup.

9bece2b313 additional renames of Curl_ourerrno => Curl_sockerrno 2006-05-05 10:24:27 +00:00
Daniel Stenberg
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.

6e61939382 GnuTLS support added. There's now a "generic" SSL layer that we use all over 
internally, with code provided by sslgen.c. All SSL-layer-specific code is
then written in ssluse.c (for OpenSSL) and gtls.c (for GnuTLS).

As far as possible, internals should not need to know what SSL layer that is
in use. Building with GnuTLS currently makes two test cases fail.

TODO.gnutls contains a few known outstanding issues for the GnuTLS support.

GnuTLS support is enabled with configure --with-gnutls

1401d909e8 Fix the "lingering close" problem when re-using a connection, as test case 
160 shows.

We got no data and we attempted to re-use a connection. This might happen if
the connection was left alive when we were done using it before, but that was
closed when we wanted to read from it again. Bad luck. Retry the same request
on a fresh connect!

Deleted the sockerror variable again, it serves no purpose anymore.
