                                  Changelog

Daniel S (5 October 2007)
- Michael Wallner made the CULROPT_COOKIELIST option support a new magic
  string: "FLUSH". Using that will cause libcurl to flush its cookies to the
  CURLOPT_COOKIEJAR file.

- The new file docs/libcurl/ABI describes how we view ABI breakages, soname
  bumps and what the version number's significance to all that is.

Daniel S (4 October 2007)
- I enabled test 1009 and made the --local-port use a wide range to reduce the
  risk of failures.

- 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'll add it in disabled state.

Yang Tse (3 October 2007)
- Fixed issue related with the use of ares_timeout() result.

Daniel S (3 October 2007)
- 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 renamed the CURLE_SSL_PEER_CERTIFICATE error code to
  CURLE_PEER_FAILED_VERIFICATION (standard CURL_NO_OLDIES style), and made
  this return code get used by the previous SSH MD5 fingerprint check in case
  it fails.

- Based on a patch brought by Johnny Luong, libcurl now offers
  CURLOPT_SSH_HOST_PUBLIC_KEY_MD5 and the curl tool --hostpubmd5. They both
  make the SCP or SFTP connection verify the remote host's md5 checksum of the
  public key before doing a connect, to reduce the risk of a man-in-the-middle
  attack.

Daniel S (2 October 2007)
- libcurl now handles chunked-encoded CONNECT responses

Daniel S (1 October 2007)
- Alex Fishman reported a curl_easy_escape() problem that was made the
  function do wrong on all input bytes that are >= 0x80 (decimal 128) due to a
  signed / unsigned mistake in the code. I fixed it and added test case 543 to
  verify.

Daniel S (29 September 2007)
- Immanuel Gregoire fixed a problem with persistent transfers over SFTP.

Daniel S (28 September 2007)
- Adapted the c-ares code to the API change c-ares 1.5.0 brings in the
  notifier callback(s).

Dan F (26 September 2007)
- Enabled a few more gcc warnings with --enable-debug.  Renamed a few
  variables to avoid shadowing global declarations.

Daniel S (26 September 2007)
- Philip Langdale provided the new CURLOPT_POST301 option for
  curl_easy_setopt() that alters how libcurl functions when following
  redirects. It makes libcurl obey the RFC2616 when a 301 response is received
  after a non-GET request is made. Default libcurl behaviour is to change
  method to GET in the subsequent request (like it does for response code 302
  - because that's what many/most browsers do), but with this CURLOPT_POST301
  option enabled it will do what the spec says and do the next request using
  the same method again. I.e keep POST after 301. 

  The curl tool got this option as --post301

  Test case 1011 and 1012 were added to verify.

- Max Katsev reported that when doing a libcurl FTP request with
  CURLOPT_NOBODY enabled but not CURLOPT_HEADER, libcurl wouldn't do TYPE
  before it does SIZE which makes it less useful. I walked over the code and
  made it do this properly, and added test case 542 to verify it.

Daniel S (24 September 2007)
- Immanuel Gregoire fixed KNOWN_BUGS #44: --ftp-method nocwd did not handle
  URLs ending with a slash properly (it should list the contents of that
  directory). Test case 351 brought back and also test 1010 was added.

Daniel S (21 September 2007)
- Mark Davies fixed Negotiate authentication over proxy, and also introduced
  the --proxy-negotiate command line option to allow a user to explicitly
  select it.

Daniel S (19 September 2007)
- Rob Crittenden provided an NSS update with the following highlights:

  o It looks for the NSS database first in the environment variable SSL_DIR,
    then in /etc/pki/nssdb, then it initializes with no database if neither of
    those exist.

  o If the NSS PKCS#11 libnspsem.so driver is available then PEM files may be
    loaded, including the ca-bundle. If it is not available then only
    certificates already in the NSS database are used.

  o Tries to detect whether a file or nickname is being passed in so the right
    thing is done

  o Added a bit of code to make the output more like the OpenSSL module,
    including displaying the certificate information when connecting in
    verbose mode

  o Improved handling of certificate errors (expired, untrusted, etc)

  The libnsspem.so PKCS#11 module is currently only available in Fedora
  8/rawhide. Work will be done soon to upstream it. The NSS module will work
  with or without it, all that changes is the source of the certificates and
  keys.

Daniel S (18 September 2007)
- Immanuel Gregoire pointed out that public key SSH auth failed if no
  public/private key was specified and there was no HOME environment variable,
  and then it didn't continue to try the other auth methods. Now it will
  instead try to get the files id_dsa.pub and id_dsa from the current
  directory if none of the two conditions were met.

Dan F (17 September 2007)
- Added hooks to the test suite to make it possible to test a curl running
  on a remote host.

- Changed some FTP tests to validate the format of the PORT and EPRT commands
  sent by curl, if not the addresses themselves.

Daniel S (15 September 2007)
- Michal Marek made libcurl automatically append ";type=<a|i>" when using HTTP
  proxies for FTP urls.

- Günter Knauf fixed LDAP builds in the Windows makefiles and fixed LDAPv3
  support on Windows.

Dan F (13 September 2007)
- Added LDAPS, SCP and SFTP to curl-config --protocols. Removed and
  fixed some AC_SUBST configure entries.

Version 7.17.0 (13 September 2007)

Daniel S (12 September 2007)
- Bug report #1792649 (http://curl.haxx.se/bug/view.cgi?id=1792649) pointed
  out a problem with doing an empty upload over FTP on a re-used connection.
  I added test case 541 to reproduce it and to verify the fix.

- I noticed while writing test 541 that the FTP code wrongly did a CWD on the
  second transfer as it didn't store and remember the "" path from the
  previous transfer so it would instead CWD to the entry path as stored. This
  worked, but did a superfluous command. Thus, test case 541 now also verifies
  this fix.

Dan F (5 September 2007)
- Added test case 1007 to test permission problem when uploading with TFTP
  (to validate bug #1790403).

- TFTP now reports the "not defined" TFTP error code 0 as an error,
  not success.

Daniel S (5 September 2007)
- Continued the work on a fix for #1779054
  (http://curl.haxx.se/bug/view.cgi?id=1779054). My previous fix from August
  24 was not complete (either) but could accidentally "forget" parts of a
  server response which led to faulty server response time-out errors.

Dan F (5 September 2007)
- Minix doesn't support getsockopt on UDP sockets or send/recv on TCP
  sockets.

Dan F (31 August 2007)
- Made some of the error strings returned by the *strerror functions more
  generic, and more consistent with each other.

- Renamed the curl_ftpssl enum to curl_usessl and its enumerated constants,
  creating macros for backward compatibility:

    CURLFTPSSL_NONE => CURLUSESSL_NONE
    CURLFTPSSL_TRY => CURLUSESSL_TRY
    CURLFTPSSL_CONTROL => CURLUSESSL_CONTROL
    CURLFTPSSL_ALL => CURLUSESSL_ALL
    CURLFTPSSL_LAST => CURLUSESSL_LAST

Dan F (30 August 2007)
- 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.

  The following unused error codes were removed:
