                                   Changelog
 
+Version 7.16.2 (11 April 2007)
+
+Yang Tse (10 April 2007)
+- Ravi Pratap provided some fixes for HTTP pipelining
+
+- configure script will ignore --enable-sspi option for non-native Windows.
+
+Daniel S (9 April 2007)
+- Nick Zitzmann did ssh.c cleanups
+
+Daniel S (3 April 2007)
+- Rob Jones fixed better #ifdef'ing for a bunch of #include lines.
+
+Daniel S (2 April 2007)
+- Nick Zitzmann made the CURLOPT_POSTQUOTE option work for SFTP as well. The
+  accepted commands are as follows:
+
+  chgrp (gid) (path)
+    Changes the group ID of the file or directory at (path) to (gid). (gid)
+    must be a number.
+
+  chmod (perms) (path)
+    Changes the permissions of the file or directory at (path) to
+    (perms). (perms) must be a number in the format used by the chmod Unix
+    command.
+
+  chown (uid) (path)
+    Changes the user ID of the file or directory at (path) to (uid). (uid)
+    must be a number.
+
+  ln (source) (dest)
+    Creates a symbolic link at (dest) that points to the file located at
+    (source).
+
+  mkdir (path)
+    Creates a new directory at (path).
+
+  rename (source) (dest)
+    Moves the file or directory at (source) to (dest).
+
+  rm (path)
+    Deletes the file located at (path).
+
+  rmdir (path)
+    Deletes the directory located at (path). This command will raise an error
+    if the directory is not empty.
+
+  symlink (source) (dest)
+    Same as ln.
+
+Daniel S (1 April 2007)
+- Robert Iakobashvili made curl_multi_remove_handle() a lot faster when many
+  easy handles are added to a multi handle, by avoiding the looping over all
+  the handles to find which one to remove.
+
+- Matt Kraai provided a patch that makes curl build on QNX 6 fine again.
+
+Daniel S (31 March 2007)
+- Fixed several minor issues detected by the coverity.com scanner.
+
+- "Pixel" fixed a problem that appeared when you used -f with user+password
+  embedded in the URL.
+
+Dan F (29 March 2007)
+- Don't tear down the ftp connection if the maximum filesize was exceeded
+  and added tests 290 and 291 to check.
+
+- Added ftps upload and SSL required tests 401 and 402.
+
+- Send an EOF message before closing an SCP channel, as recommended by
+  RFC4254. Enable libssh2 tracing when ssh debugging is turned on.
+
+Yang Tse (27 March 2007)
+- Internal function Curl_select() renamed to Curl_socket_ready()
+
+  New Internal wrapper function Curl_select() around select (2), it
+  uses poll() when a fine poll() is available, so now libcurl can be
+  built without select() support at all if a fine poll() is available.
+
+Daniel S (25 March 2007)
+- Daniel Johnson fixed multi code to traverse the easy handle list properly.
+  A left-over bug from the February 21 fix.
+
+Dan F (23 March 2007)
+- Added --pubkey option to curl and made --key also work for SCP/SFTP,
+  plus made --pass work on an SSH private key as well.
+
+- Changed the test harness to attempt to gracefully shut down servers
+  before resorting to the kill -9 hammer.
+
+- Added test harness infrastructure to support scp/sftp tests, using
+  OpenSSH as the server.
+
+- Fixed a memory leak when specifying a proxy with a file: URL.
+
+Yang Tse (20 March 2007)
+- Fixed: When a signal was caught awaiting for an event using Curl_select()
+  or Curl_poll() with a non-zero timeout both functions would restart the
+  specified timeout. This could even lead to the extreme case that if a
+  signal arrived with a frecuency lower to the specified timeout neither
+  function would ever exit.
+
+  Added experimental symbol definition check CURL_ACKNOWLEDGE_EINTR in
+  Curl_select() and Curl_poll(). When compiled with CURL_ACKNOWLEDGE_EINTR
+  defined both functions will return as soon as a signal is caught. Use it
+  at your own risk, all calls to these functions in the library should be
+  revisited and checked before fully supporting this feature.
+
+Yang Tse (19 March 2007)
+- Bryan Henderson fixed the progress function so that it can get called more
+  frequently allowing same calling frecuency for the client progress callback.
+  
+Dan F (15 March 2007)
+- Various memory leaks plugged and NULL pointer fixes made in the ssh code.
+
+Daniel (15 March 2007)
+- Nick made the curl tool accept globbing ranges that only is one number, i.e
+  you can now use [1-1] without curl complaining.
+
+Daniel (10 March 2007)
+- Eygene Ryabinkin:
+
+  The problem is the following: when we're calling Curl_done and it decides to
+  keep the connection opened ('left intact'), then the caller is not notified
+  that the connection was done via the NULLifying of the pointer, so some easy
+  handle is keeping the pointer to this connection.
+
+  Later ConnectionExists can select such connection for reuse even if we're
+  not pipelining: pipeLen is zero, so the (pipeLen > 0 && !canPipeline) is
+  false and we can reuse this connection for another easy handle. But thus the
+  connection will be shared between two easy handles if the handle that wants
+  to take the ownership is not the same as was not notified of the connection
+  was done in Curl_done. And when some of these easy handles will get their
+  connection really freed the another one will still keep the pointer.
+
+  My fix was rather trivial: I just added the NULLification to the 'else'
+  branch in the Curl_done. My tests with Git and ElectricFence showed no
+  problems both for HTTP pulling and cloning. Repository size is about 250 Mb,
+  so it was a considerable amount of Curl's work.
+
+Dan F (9 March 2007)
+- Updated the test harness to add a new "crypto" feature check and updated the
+  appropriate test case to use it.  For now, this is treated the same as the
+  "SSL" feature because curl doesn't list it separately.
+
+Daniel (9 March 2007)
+- Robert Iakobashvili fixed CURLOPT_INTERFACE for IPv6.
+
+- Robert A. Monat improved the maketgz and VC6/8 generating to set the correct
+  machine type too.
+
+- Justin Fletcher fixed a file descriptor leak in the curl tool when trying to
+  upload a file it couldn't open. Bug #1676581
+  (http://curl.haxx.se/bug/view.cgi?id=1676581)
+
+Dan F (9 March 2007)
+- Updated the test harness to check for protocol support before running each
+  test, fixing KNOWN_BUGS #11.
+
+Dan F (7 March 2007)
+- Reintroduced (after a 3 year hiatus) an FTPS test case (400) into the test
+  harness.  It is very limited as it supports only ftps:// URLs with
+  --ftp-ssl-control specified, which implicitly encrypts the control
+  channel but not the data channels.  That allows stunnel to be used with
+  an unmodified ftp server in exactly the same way that the test https
+  server is set up.
+
+Dan F (7 March 2007)
+- Honour --ftp-ssl-control on ftps:// URLs to allow encrypted control and
+  unencrypted data connections.
+
+Dan F (6 March 2007)
+- Fixed a couple of improper pointer uses detected by valgrind in test
+  cases 181 & 216.
+
+Daniel (2 March 2007)
+- Robert A. Monat and Shmulik Regev helped out to fix the new */Makefile.vc8
+  makefiles that are included in the source release archives, generated from
+  the Makefile.vc6 files by the maketgz script. I also modified the root
+  Makefile to have a VC variable that defaults to vc6 but can be overridden to
+  allow it to be used for vc8 as well. Like this:
+
+    nmake VC=vc8 vc
+
+Daniel (27 February 2007)
+- Hang Kin Lau found and fixed: When I use libcurl to connect to an https
+  server through a proxy and have the remote https server port set using the
+  CURLOPT_PORT option, protocol gets reset to http from https after the first
+  request.
+ 
+  User defined URL was modified internally by libcurl and subsequent reuse of
+  the easy handle may lead to connection using a different protocol (if not
+  originally http).
+ 
+  I found that libcurl hardcoded the protocol to "http" when it tries to
+  regenerate the URL if CURLOPT_PORT is set. I tried to fix the problem as
+  follows and it's working fine so far
+
+Daniel (25 February 2007)
+- Adam D. Moss made the HTTP CONNECT procedure less blocking when used from
+  the multi interface. Note that it still does a part of the connection in a
+  blocking manner.
+
+Daniel (23 February 2007)
+- Added warning outputs if the command line uses more than one of the options
+  -v, --trace and --trace-ascii, since it could really confuse the user.
+  Clarified this fact in the man page.
+
+Daniel (21 February 2007)
+- Ravi Pratap provided work on libcurl making pipelining more robust and
+  fixing some bugs:
+  o Don't mix GET and POST requests in a pipeline
+  o Fix the order in which requests are dispatched from the pipeline
+  o Fixed several curl bugs with pipelining when the server is returning
+    chunked encoding:
+    * Added states to chunked parsing for final CRLF
+    * Rewind buffer after parsing chunk with data remaining
+    * Moved chunked header initializing to a spot just before receiving
+      headers
+
+Daniel (20 February 2007)
+- Linus Nielsen Feltzing changed the CURLOPT_FTP_SSL_CCC option to handle
+  active and passive CCC shutdown and added the --ftp-ssl-ccc-mode command
+  line option.
+
+Daniel (19 February 2007)
+- Ian Turner fixed the libcurl.m4 macro's support for --with-libcurl.
+
+- Shmulik Regev found a memory leak in re-used HTTPS connections, at least
+  when the multi interface was used.
+
+- Robson Braga Araujo made passive FTP transfers work with SOCKS (both 4 and
+  5).
+
+Daniel (18 February 2007)
+- Jeff Pohlmeyer identified two problems: first a rather obscure problem with
+  the multi interface and connection re-use that could make a
+  curl_multi_remove_handle() ruin a pointer in another handle.
+
+  The second problem was less of an actual problem but more of minor quirk:
+  the re-using of connections wasn't properly checking if the connection was
+  marked for closure.
+
+Daniel (16 February 2007)
+- Duncan Mac-Vicar Prett and Michal Marek reported problems with resetting
+  CURLOPT_RANGE back to no range on an easy handle when using FTP.
+
+Dan F (14 February 2007)
+- Fixed curl-config --libs so it doesn't list unnecessary libraries (and
+  therefore introduce unnecessary dependencies) when it's not needed.
+  Also, don't bother adding a library path of /usr/lib
+
+Daniel (13 February 2007)
+- The default password for anonymous FTP connections is now changed to be
+  "ftp@example.com".
+
+- Robert A. Monat made libcurl build fine with VC2005 - it doesn't have
+  gmtime_r() like the older VC versions. He also made use of some machine-
+  specific defines to differentiate the "OS" define.
+
+Daniel (12 February 2007)
+- Rob Crittenden added support for NSS (Network Security Service) for the
+  SSL/TLS layer. http://www.mozilla.org/projects/security/pki/nss/
+
+  This is the fourth supported library for TLS/SSL that libcurl supports!
+
+- Shmulik Regev fixed so that the final CRLF of HTTP response headers are sent
+  to the debug callback.
+
+- Shmulik Regev added CURLOPT_HTTP_CONTENT_DECODING and
+  CURLOPT_HTTP_TRANSFER_DECODING that if set to zero will disable libcurl's
+  internal decoding of content or transfer encoded content. This may be
+  preferable in cases where you use libcurl for proxy purposes or similar. The
+  command line tool got a --raw option to disable both at once.
+
+- release tarballs made with maketgz will from now on have a LIBCURL_TIMESTAMP
+  define set to hold the exact date and time of when the tarball was built, as
+  a human readable string using the UTC time zone.
+  
+- Jeff Pohlmeyer fixed a flaw in curl_multi_add_handle() when adding a handle
+  that has an easy handle present in the "closure" list pending closure.
+
+Daniel (6 February 2007)
+- Regular file downloads wiht SFTP and SCP are now done using the non-blocking
+  API of libssh2, if the libssh2 headers seem to support them. This will make
+  SCP and SFTP much more responsive and better libcurl citizens when used with
+  the multi interface etc.
+
+Daniel (5 February 2007)
+- Michael Wallner added support for CURLOPT_TIMEOUT_MS and
+  CURLOPT_CONNECTTIMEOUT_MS that, as their names suggest, do the timeouts with
+  millisecond resolution. 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.
+
+Daniel (3 February 2007)
+- Yang Tse fixed the cookie expiry date in several test cases that started to
+  fail since they used "1 feb 2007"...
+
+- Manfred Schwarb reported that socks5 support was broken and help us pinpoint
+  the problem. The code now tries harder to use httproxy and proxy where
+  apppropriate, as not all proxies are HTTP...
+

+.TH ARES_PARSE_NS_REPLY 3 "10 February 2007"
+.SH NAME
+ares_parse_ns_reply \- Parse a reply to a DNS query of type NS into a hostent
+.SH SYNOPSIS
+.nf
+.B #include <ares.h>
+.PP
+.B int ares_parse_ns_reply(const unsigned char *\fIabuf\fP, int \fIalen\fP,
+.B 	struct hostent **\fIhost\fP);
+.fi
+.SH DESCRIPTION
+The
+.B ares_parse_ns_reply
+function parses the response to a query of type NS into a
+.BR "struct hostent" .
+The parameters
+.I abuf
+and
+.I alen
+give the contents of the response.  The result is stored in allocated
+memory and a pointer to it stored into the variable pointed to by
+.IR host . 
+The nameservers are stored into the 
+.BR aliases 
+field of the 
+.IR host 
+structure. 
+It is the caller's responsibility to free the resulting host structure
+using
+.BR ares_free_hostent (3)
+when it is no longer needed.
+.SH RETURN VALUES
+.B ares_parse_ns_reply
+can return any of the following values:
+.TP 15
+.B ARES_SUCCESS
+The response was successfully parsed.
+.TP 15
+.B ARES_EBADRESP
+The response was malformatted.
+.TP 15
+.B ARES_ENODATA
+The response did not contain an answer to the query.
+.TP 15
+.B ARES_ENOMEM
+Memory was exhausted.
+.SH SEE ALSO
+.BR ares_query (3),
+.BR ares_free_hostent (3)

-Fixing the Only Problem
-
- The only problem is thus for distributions that want to offer libcurl
- versions built with more than one SSL/TLS library.
-
- Since multiple libcurl binaries using different names are ruled out, we need
- to come up with a way to have one single libcurl that someone uses different
- underlying libraries. The best(?) approach currently suggested involves this:
-
- A new intermediate library (named lib2 so far in the discussions) with the
- single purpose of providing libcurl with SSL/TLS capabilities. It would have
- a unified API and ABI no matter what underlying library it would use.
-
- There would be one lib2 binary provided for each supported SSL/TLS library.
- For example: lib2-openssl, lib2-gnutls, lib2-yassl, lib2-matrixssl and
- lib2-nossl. Yes, take note of the last one that provides the lib2 ABI but
- that lacks the actual powers.
-
- When libcurl is built and linked, it will be linked against a lib2 with the
- set ABI.
-
- When you link an app against libcurl, it would also need to provide one of
- the (many) lib2 libs to decide what approach that fits the app. An app that
- doesn't want SSL at all would still need to link with the lib2-nossl lib.
-
- GPL apps can pick the lib2-gnutls, others may pick the lib2-openssl.
-
- This concept works equally well both for shared and static libraries.
-
- A positive side effect of this approach could be a more generic "de facto"
- standard API for SSL/TLS libraries.
-
-When Will This Happen
-
- This is not a problem in curl, it doesn't solve any actual technical problems
- in our project. Don't hold your breath for this to happen very soon (if at
- all) unless you step forward and contribute.
-
- The suggestion that is outlined above is still only a suggestion. Feel free
- to bring a better idea!
-
- Also, to keep in mind: I don't want this new concept to have too much of an
- impact on the existing code. Preferably it should be possible to build the
- code like today (without the use of lib2), should you decide to ignore the
- problems outlined in this document.
