                                  Changelog

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:

    CURLE_BAD_CALLING_ORDER
    CURLE_BAD_PASSWORD_ENTERED
    CURLE_FTP_CANT_RECONNECT
    CURLE_FTP_COULDNT_GET_SIZE
    CURLE_FTP_COULDNT_SET_ASCII
    CURLE_FTP_USER_PASSWORD_INCORRECT
    CURLE_FTP_WEIRD_USER_REPLY
    CURLE_FTP_WRITE_ERROR
    CURLE_LIBRARY_NOT_FOUND
    CURLE_MALFORMAT_USER
    CURLE_OBSOLETE
    CURLE_SHARE_IN_USE
    CURLE_URL_MALFORMAT_USER

  The following error codes were renamed:

    CURLE_FTP_ACCESS_DENIED =>      CURLE_REMOTE_ACCESS_DENIED
    CURLE_FTP_COULDNT_SET_BINARY => CURLE_FTP_COULDNT_SET_TYPE
    CURLE_FTP_SSL_FAILED =>         CURLE_USE_SSL_FAILED
    CURLE_FTP_QUOTE_ERROR =>        CURLE_QUOTE_ERROR
    CURLE_TFTP_DISKFULL =>          CURLE_REMOTE_DISK_FULL
    CURLE_TFTP_EXISTS =>            CURLE_REMOTE_FILE_EXISTS
    CURLE_HTTP_RANGE_ERROR =>       CURLE_RANGE_ERROR 

  The following options were renamed:

    CURLOPT_SSLKEYPASSWD => CURLOPT_KEYPASSWD 
    CURLOPT_FTPAPPEND =>    CURLOPT_APPEND
    CURLOPT_FTPLISTONLY =>  CURLOPT_DIRLISTONLY
    CURLOPT_FTP_SSL =>      CURLOPT_USE_SSL

  A few more changes will take place with the next SONAME bump of the
  library.  These are documented in docs/TODO

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

- Added more accurate error code returns from SFTP operations.  Added test
  case 615 to test an SFTP upload failure.

Dan F (28 August 2007)
- Some minor internal type and const changes based on a splint scan.

Daniel S (24 August 2007)
- Bug report #1779054 (http://curl.haxx.se/bug/view.cgi?id=1779054) pointed
  out that libcurl didn't deal with large responses from server commands, when
  the single response was consisting of multiple lines but of a total size of
  16KB or more. Dan Fandrich improved the ftp test script and provided test
  case 1006 to repeat the problem, and I fixed the code to make sure this new
  test case runs fine.

Patrick M (23 August 2007)
- OS/400 port: new files lib/config-os400.h lib/setup-os400.h packages/OS400/*.
  See packages/OS400/README.OS400.

Daniel S (23 August 2007)
- Bug report #1779751 (http://curl.haxx.se/bug/view.cgi?id=1779751) pointed
  out that doing first a file:// upload and then an FTP upload crashed libcurl
  or at best caused furious valgrind complaints. Fixed now!

Daniel S (22 August 2007)
- Bug report #1779054 (http://curl.haxx.se/bug/view.cgi?id=1779054) pointed
  out that libcurl didn't deal with very long (>16K) FTP server response lines
  properly. Starting now, libcurl will chop them off (thus the client app will
  not get the full line) but survive and deal with them fine otherwise. Test
  case 1003 was added to verify this.

Daniel S (20 August 2007)
- Based on a patch by Christian Vogt, the FTP code now sets the upcoming
  download transfer size much earlier to be possible to get read with
  CURLINFO_CONTENT_LENGTH_DOWNLOAD as soon as possible. This is very much in a
  similar spirit to the HTTP size change from August 11 2007.

Daniel S (18 August 2007)
- Robson Braga Araujo filed bug report #1776232
  (http://curl.haxx.se/bug/view.cgi?id=1776232) about libcurl calling
  Curl_client_write(), passing on a const string that the caller may not
  modify and yet it does (on some platforms).

- Robson Braga Araujo filed bug report #1776235
  (http://curl.haxx.se/bug/view.cgi?id=1776235) about ftp requests with NOBODY
  on a directory would do a "SIZE (null)" request. This is now fixed and test
  case 1000 was added to verify.

Daniel S (17 August 2007)
- Song Ma provided a patch that cures a problem libcurl has when doing resume
  HTTP PUT using Digest authentication. Test case 5320 and 5322 were also
  added to verify the functionality.

Daniel S (14 August 2007)
- Andrew Wansink provided an NTLM bugfix: in the case the server sets the flag
  NTLMFLAG_NEGOTIATE_UNICODE, we need to filter it off because libcurl doesn't
  UNICODE encode the strings it packs into the NTLM authenticate packet.

Daniel S (11 August 2007)
- Allen Pulsifer provided a patch that makes libcurl set the expected download
  size earlier when doing HTTP downloads, so that applications and the
  progress meter etc know get the info earlier in the flow than before.

- Patrick Monnerat modified the LDAP code and approach in curl. Starting now,
  the configure script checks for openldap and friends and we link with those
  libs just like we link all other third party libraries, and we no longer
  dlopen() those libraries. Our private header file lib/ldap.h was renamed to
  lib/curl_ldap.h due to this. I set a tag in CVS (curl-7_17_0-preldapfix)
  just before this commit, just in case.

Dan F (8 August 2007)
- Song Ma noted a zlib memory leak in the illegal compressed header
  countermeasures code path.

Daniel S (4 August 2007)
- Patrick Monnerat fixed curl_easy_escape() and curlx_strtoll() to work on
  non-ASCII systems.

Daniel S (3 August 2007)
- I cut out support for libssh2 versions older than 0.16 to make our code a
  lot simpler, and to avoid getting trouble with the LIBSSH2_APINO define
  that 1) didn't work properly since it was >32 bits and 2) is removed in
  libssh2 0.16...

Daniel S (2 August 2007)
- Scott Cantor filed bug report #1766320
  (http://curl.haxx.se/bug/view.cgi?id=1766320) pointing out that the libcurl
  code accessed two curl_easy_setopt() options (CURLOPT_DNS_CACHE_TIMEOUT and
  CURLOPT_DNS_USE_GLOBAL_CACHE) as ints even though they're documented to be
  passed in as longs, and that makes a difference on 64 bit architectures.

- Dmitriy Sergeyev reported a regression: resumed file:// transfers broke
  after 7.16.2. This is much due to the different treatment file:// gets
  internally, but now I added test 231 to make it less likely to happen again
  without us noticing!

Daniel S (1 August 2007)
- 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. This is also part of Patrick Monnerat's
  OS/400 port.

  Due to this being a somewhat interesting change API wise, I've decided to
  bump the version of the upcoming release to 7.17.0. Older applications will
  of course not notice this change nor do they have to care, but new
  applications can be written to take advantage of this.

- Greg Morse reported a problem with POSTing using ANYAUTH to a server
  requiring NTLM, and he provided test code and a test server and we worked
  out a bug fix. We failed to count sent body data at times, which then caused
  internal confusions when libcurl tried to send the rest of the data in order
  to maintain the same connection alive.

Daniel S (31 July 2007)
- Peter O'Gorman pointed out (and fixed) that the non-blocking check in
  configure made libcurl use blocking sockets on AIX 4 and 5, while that
  wasn't the intention.

Daniel S (29 July 2007)
- Jayesh A Shah filed bug report #1759542
  (http://curl.haxx.se/bug/view.cgi?id=1759542) identifying a rather serious
  problem with FTPS: libcurl closed the data connection socket and then later
  in the flow it would call the SSL layer to do SSL shutdown which then would
  use a socket that had already been closed - so if the application had opened
  a new one in the mean time, libcurl could send gibberish that way! I worked
  with Greg Zavertnik to properly diagnose and fix this. The fix affects code
  for all SSL libraries we support, but it has only been truly verified to
  work fine for the OpenSSL version. The others have only been code reviewed.

Daniel S (23 July 2007)
- Implemented the parts of Patrick Monnerat's OS/400 patch that introduces
