                                  Changelog

Daniel S (4 Jan 2008)
- Based on Maxim Perenesenko's patch, we now do SOCKS5 operations and let the
  proxy do the host name resolving and only if --socks5ip (or
  CURLOPT_SOCKS5_RESOLVE_LOCAL) is used we resolve the host name locally and
  pass on the IP address only to the proxy.

Yang Tse (3 Jan 2008)
- Modified test harness to allow SCP, SFTP and SOCKS4 tests to run with
  OpenSSH 2.9.9, SunSSH 1.0 or later versions. SOCKS5 tests need OpenSSH
  3.7, SunSSH 1.0 or later.

Daniel S (2 Jan 2008)
- I fixed two cases of missing return code checks when handling chunked
  decoding where a write error (or abort return from a callback) didn't stop
  libcurl's processing.

- I removed the socklen_t use from the public curl/curl.h header and instead
  made it an unsigned int. The type was only used in the curl_sockaddr struct
  definition (only used by the curl_opensocket_callback). On all platforms I
  could find information about, socklen_t is 32 unsigned bits large so I don't
  think this will break the API or ABI. The main reason for this change is of
  course for all the platforms that don't have a socklen_t definition in their
  headers to build fine again. Providing our own configure magic and custom
  definition of socklen_t on those systems proved to work but was a lot of
  cruft, code and extra magic needed - when this very small change of type
  seems harmless and still solves the missing socklen_t problem.

- Richard Atterer brought a patch that added support for SOCKS4a proxies,
  which is an inofficial PROXY4 variant that sends the hostname to the proxy
  instead of the resolved address (which is already supported by SOCKS5).
  --socks4a is the curl command line option for it and CURLOPT_PROXYTYPE can
  now be set to CURLPROXY_SOCKS4A as well.

Daniel S (1 Jan 2008)
- Mohun Biswas pointed out that --libcurl generated a source code with an int
  function but without a return statement. While fixing that, I also took care
  about adding some better comments for the generated code.

Daniel S (27 Dec 2007)
- Dmitry Kurochkin mentioned a flaw
  (http://curl.haxx.se/mail/lib-2007-12/0252.html) in detect_proxy() which
  failed to set the bits.proxy variable properly when an environment variable
  told libcurl to use a http proxy.

Daniel S (26 Dec 2007)
- In an attempt to repeat the problem in bug report #1850730
  (http://curl.haxx.se/bug/view.cgi?id=1850730) I wrote up test case 552. The
  test is doing a 70K POST with a read callback and an ioctl callback over a
  proxy requiring Digest auth. The test case code is more or less identical to
  the test recipe code provided by Spacen Jasset (who submitted the bug
  report).

Daniel S (25 Dec 2007)
- Gary Maxwell filed bug report #1856628
  (http://curl.haxx.se/bug/view.cgi?id=1856628) and provided a fix for the
  (small) memory leak in the SSL session ID caching code. It happened when a
  previous entry in the cache was re-used.

Daniel Fandrich (19 Dec 2007)
- Ensure that nroff doesn't put anything but ASCII characters into the
  --manual text.

Yang Tse (18 Dec 2007)
- MSVC 9.0 (VS2008) does not support Windows build targets prior to WinXP,
  and makes wrong asumptions of build target when it isn't specified. So,
  if no build target has been defined we will target WinXP when building
  curl/libcurl with MSVC 9.0 (VS2008).

- (http://curl.haxx.se/mail/archive-2007-12/0039.html) reported and fixed
  a file truncation problem on Windows build targets triggered when retrying
  a download with curl.

Daniel S (17 Dec 2007)
- Mateusz Loskot pointed out that MSVC 9.0 (VS2008) has the pollfd struct and
  defines in winsock2.h somehow differently than previous versions and that
  curl 7.17.1 would fail to compile out of the box.

Daniel S (13 Dec 2007)
- David Wright filed bug report #1849764
  (http://curl.haxx.se/bug/view.cgi?id=1849764) with an included fix. He
  identified a problem for re-used connections that previously had sent
  Expect: 100-continue and in some situations the subsequent POST (that didn't
  use Expect:) still had the internal flag set for its use. David's fix (that
  makes the setting of the flag in every single request unconditionally) is
  fine and is now used!

Daniel S (12 Dec 2007)
- Gilles Blanc made the curl tool enable SO_KEEPALIVE for the connections and
  added the --no-keep-alive option that can disable that on demand.

Daniel S (9 Dec 2007)
- Andrew Moise filed bug report #1847501
  (http://curl.haxx.se/bug/view.cgi?id=1847501) and pointed out a memcpy()
  that should be memmove() in the convert_lineends() function.

Daniel S (8 Dec 2007)
- Renamed all internal static functions that had Curl_ prefixes to no longer
  have them. The Curl_ prefix is exclusively used for library internal global
  symbols. Static functions can be named anything, except for using Curl_ or
  curl_ prefixes. This is for consistency and for easier maintainance and
  overview.

- Cleaned up and reformatted the TODO document to look like the FAQ and
  CONTRIBUTE, which makes nicer web pages

- Added test cases 549 and 550 that test CURLOPT_PROXY_TRANSFER_MODE.

- Added keywords on a bunch of test cases

- Fixed an OOM problem in the curl code that would lead to fclose on a bad
  handle and crash

Daniel S (5 Dec 2007)
- Spacen Jasset reported a problem with doing POST (with data read with a
  callback) over a proxy when NTLM is used as auth with the proxy. The bug
  also concerned Digest and was limited to using callback only. Spacen worked
  with us to provide a useful patch. I added the test case 547 and 548 to
  verify two variations of POST over proxy with NTLM.

Daniel S (3 Dec 2007)
- Ray Pekowski filed bug report #1842029
  (http://curl.haxx.se/bug/view.cgi?id=1842029) in which he identified a
  problem with SSL session caching that prevent it from working, and provided
  the associated fix!

- Now libcurl (built with OpenSSL) doesn't return error anymore if the remote
  SSL-based server doesn't present a certificate when the request is told to
  ignore certificate verification anyway.

- Michal Marek introduced CURLOPT_PROXY_TRANSFER_MODE which is used to control
  the appending of the "type=" thing on FTP URLs when they are passed to a
  HTTP proxy. Some proxies just don't like that appending (which is done
  unconditionally in 7.17.1), and some proxies treat binary/ascii transfers
  better with the appending done!

Daniel S (29 Nov 2007)
- A bug report on the curl-library list showed a HTTP Digest session going on
  with a 700+ letter nonce. Previously libcurl only support 127 letter ones
  and now I bumped it to 1023.

- Fixed the resumed FTP upload loop to not require that the read callback
  returns a full buffer on each invoke.

Daniel S (25 Nov 2007)
- Added test case 1015 that tests --data-urlencode in multiple ways

- Fixed --data-urlencode for when no @ or = are used

- Extended the user-agent buffer curl uses, since we can hit the 128 byte
  border with plenty development libraries used. Like my current set: "curl
  7.17.2-CVS (i686-pc-linux-gnu) libcurl/7.17.2-CVS OpenSSL/0.9.8g
  zlib/1.2.3.3 c-ares/1.5.2-CVS libidn/1.1 libssh2/0.19.0-CVS"

Daniel S (24 Nov 2007)
- Internal rearrangements, so that the previous struct HandleData is no more.
  It is now known as SingleRequest and the Curl_transfer_keeper struct within
  that was remove entirely. This has the upside that there are less duplicate
  struct members that made it hard to see and remember what struct that was
  used to store what data. The transfer_keeper thing was once stored on a
  per-connection basis and then it made sense to have the duplicate info but
  since it was moved to the SessionHandle (in 7.16.0) it just added weirdness.
  The SingleRequest struct is used by data that only is valid for this single
  request.

Yang Tse (22 Nov 2007)
- Provide a socklen_t definition in curl.h for Win32 API build targets
  which don't have one.

Daniel S (22 Nov 2007)
- Alessandro Vesely helped me improve the --data-urlencode's syntax, parser
  and documentation.

Daniel S (21 Nov 2007)
- While inspecting the Negotiate code, I noticed how the proxy auth was using
  the same state struct as the host auth, so both could never be used at the
  same time! I fixed it (without being able to check) to use two separate
  structs to allow authentication using Negotiate on host and proxy
  simultaneously.

Daniel S (20 Nov 2007)
- Emil Romanus pointed out a bug that made an easy handle get the cookie
  engine activated when set to use a share (even if the share doesn't share
  cookies). I fixed it.

- Fixed a very long-lasting mprintf() bug that occurred when we did "%.*s%s",
  since the second %s would then wrongly used the numerical precision argument
  instead and crash.

- Introduced --data-urlencode to the curl tool for easier url encoding of the
  data sent in a post.
