+ o auth fix for HTTP redirects and .netrc usage
- o getting user name from http_proxy env variable works now
+ o FTP uploads show the progress meter easier
- o fixed too early name resolve timeouts with ares
+ o MSVC makefile fixes for static libcurl builds
- o HTTP Digest "re-negotiation" works now
+ o configure fix for static libcurl build on Windows
- o CURLOPT_FAILONERROR (-f/--fail) works with all kinds of authentication
+ o --retry-delay
- o better thread-safety thanks to the internal strerror() replacement
+ o POST with read callback now uses Expect: 100-continue

   Changelog for the c-ares project
 
+* May 14
+
+- Added an inet_ntop function from BIND for systems that do not have it.
+
+* April 9
+
+- Made sortlist support IPv6 (this can probably use some testing).
+
+- Made sortlist support CIDR matching for IPv4.
+
+* April 8
+
+- Added preliminary IPv6 support to ares_gethostbyname. Currently, sortlist
+  does not work with IPv6. Also provided an implementation of bitncmp from
+  BIND for systems that do not supply this function. This will be used to add
+  IPv6 support to sortlist.
+
+- Made ares_gethostbyaddr support IPv6 by specifying AF_INET6 as the family.
+  The function can lookup IPv6 addresses both from files (/etc/hosts) and
+  DNS lookups.
+
+* April 7
+
+- Tupone Alfredo fixed includes of arpa/nameser_compat.h to build fine on Mac
+  OS X.
+
+* April 5
+
+- Dominick Meglio: Provided implementations of inet_net_pton and inet_pton
+  from BIND for systems that do not include these functions.
+
+* March 11, 2005
+
+- Dominick Meglio added ares_parse_aaaa_reply.c and did various
+  adjustments. The first little steps towards IPv6 support!
+
+* November 7
+
+- Fixed the VC project and makefile to use ares_cancel and ares_version
+
+* October 24
+
+- The released ares_version.h from 1.2.1 says 1.2.0 due to a maketgz flaw.
+  This is now fixed.
+
+Version 1.2.1 (October 20, 2004)
+
+* September 29
+
+- Henrik Stoerner fix: got a report that Tru64 Unix (the unix from Digital
+  when they made Alpha's) uses /etc/svc.conf for the purpose fixed below for
+  other OSes. He made c-ares check for and understand it if present.
+
+- Now c-ares will use local host name lookup _before_ DNS resolving by default
+  if nothing else is told.
+
+* September 26
+
+- Henrik Stoerner: found out that c-ares does not look at the /etc/host.conf
+  file to determine the sequence in which to search /etc/hosts and DNS.  So on
+  systems where this order is defined by /etc/host.conf instead of a "lookup"
+  entry in /etc/resolv.conf, c-ares will always default to looking in DNS
+  first, and /etc/hosts second.
+
+  c-ares now looks at
+
+  1) resolv.conf (for the "lookup" line);
+  2) nsswitch.fon (for the "hosts:" line);
+  3) host.conf (for the "order" line).
+
+  First match wins.
+
+- Dominick Meglio patched: C-ares on Windows assumed that the HOSTS file is
+  located in a static location. It assumed
+  C:\Windows\System32\Drivers\Etc. This is a poor assumption to make. In fact,
+  the location of the HOSTS file can be changed via a registry setting.
+
+  There is a key called DatabasePath which specifies the path to the HOSTS
+  file:
+  http://www.microsoft.com/technet/itsolutions/network/deploy/depovg/tcpip2k.mspx
+
+  The patch will make c-ares correctly consult the registry for the location
+  of this file.
+
+* August 29
+
+- Gisle Vanem fixed the MSVC build files.
+
+* August 20
+
+- Gisle Vanem made c-ares build and work with his Watt-32 TCP/IP stack.
+
+* August 13
+
+- Harshal Pradhan made a minor syntax change in ares_init.c to make it build
+  fine with MSVC 7.1
+
+* July 24
+
+- Made the lib get built static only if --enable-debug is used.
+
+- Gisle Vanem fixed:
+
+  Basically in loops like handle_errors(), 'query->next' was assigned a local
+  variable and then query was referenced after the memory was freed by
+  next_server(). I've changed that so next_server() and end_query() returns
+  the next query. So callers should use this ret-value.
+
+  The next problem was that 'server->tcp_buffer_pos' had a random value at
+  entry to 1st recv() (luckily causing Winsock to return ENOBUFS).
+
+  I've also added a ares_writev() for Windows to streamline the code a bit
+  more.
+
+* July 20
+- Fixed a few variable return types for some system calls. Made configure
+  check for ssize_t to make it possible to use that when receiving the send()
+  error code. This is necessary to prevent compiler warnings on some systems.
+
+- Made configure create config.h, and all source files now include setup.h that
+  might include the proper config.h (or a handicrafted alternative).
+
+- Switched to 'ares_socket_t' type for sockets in ares, since Windows don't
+  use 'int' for that.
+
+- automake-ified and libool-ified c-ares. Now it builds libcares as a shared
+  lib on most platforms if wanted. (This bloated the size of the release
+  archive with another 200K!)
+
+- Makefile.am now uses Makefile.inc for the c sources, h headers and man
+  pages, to make it easier for other makefiles to use the exact same set of
+  files.
+
+- Adjusted 'maketgz' to use the new automake magic when building distribution
+  archives.
+
+- Anyone desires HTML and/or PDF versions of the man pages in the release
+  archives?
+
+* July 3
+- G<>nter Knauf made c-ares build and run on Novell Netware.
+
+* July 1
+- Gisle Vanem provided Makefile.dj to build with djgpp, added a few more djgpp
+  fixes and made ares not use 'errno' to provide further info on Windows.
+
+* June 30
+- Gisle Vanem made it build with djgpp and run fine with the Watt-32 stack.
+
+* June 10
+- Gisle Vanem's init patch for Windows:
+
+  The init_by_resolv_conf() function fetches the DNS-server(s)
+  from a series of registry branches.
+
+  This can be wrong in the case where DHCP has assigned nameservers, but the
+  user has overridden these servers with other prefered settings. Then it's
+  wrong to use the DHCPNAMESERVER setting in registry.
+
+  In the case of no global DHCP-assigned or fixed servers, but DNS server(s)
+  per adapter, one has to query the adapter branches.  But how can c-ares know
+  which adapter is valid for use? AFAICS it can't. There could be one adapter
+  that is down (e.g. a VPN adapter).
+
+  So it's better to leave this to the IP Helper API (iphlapi) available in
+  Win-98/2000 and later. My patch falls-back to the old way if not available.
+
+* June 8
+- James Bursa fixed an init issue for RISC OS.
+
+* May 11
+- Nico Stappenbelt reported that when processing domain and search lines in
+  the resolv.conf file, the first entry encountered is processed and used as
+  the search list. According to the manual pages for both Linux, Solaris and
+  Tru64, the last entry of either a domain or a search field is used.
+
+  This is now adjusted in the code
+

+.SH NAME
+ares_parse_aaaa_reply \- Parse a reply to a DNS query of type AAAA into a hostent
+.SH SYNOPSIS
+.nf
+.B #include <ares.h>
+.PP
+.B int ares_parse_aaaa_reply(const unsigned char *\fIabuf\fP, int \fIalen\fP,
+.B 	struct hostent **\fIhost\fP);

+.SH DESCRIPTION
+The
+.B ares_parse_aaaa_reply
+function parses the response to a query of type AAAA 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 .
+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_aaaa_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.

   3.15 Can I do recursive fetches with curl?
 
   No. curl itself has no code that performs recursive operations, such as
-  those performed by wget.
+  those performed by wget and similar tools.
 
   There exist wrapper scripts with that functionality (for example the
   curlmirror perl script), and you can write programs based on libcurl to do
   it, but the command line tool curl itself cannot.
 
+  3.16 What certificates do I need when I use SSL?
+
+  There are three different kinds of "certificates" to keep track of when we
+  talk about using SSL-based protocols (HTTPS or FTPS) using curl or libcurl.
+
+  - Client certificate. The server you communicate may require that you can
+    provide this in order to prove that you actually are who you claim to be.
+    If the server doesn't require this, you don't need a client certificate.
+
+  - Server certificate. The server you communicate with has a server
+    certificate. You can and should verify this certificate to make sure that
+    you are truly talking to the real server and not a server impersonating
+    it. The server certificate verification process is made by using a
+    Certificate Authority certificate ("CA cert") that was used to sign the
+    server certificate. Server certificate verification is enabled by default
+    in curl and libcurl and is often the reason for problems as explained in
+    FAQ entry 4.12 and the SSLCERTS document
+    (http://curl.haxx.se/docs/sslcerts.html). Server certificates that are
+    "self-signed" or otherwise signed by a CA that you do not have a CA cert
+    for, cannot be verified. If the verification during a connect fails, you
+    are refused access. You then need to explicitly disable the verification
+    to connect to the server.
+
+  - Certificate Authority certificate ("CA cert"). You often have several CA
+    certs in a CA cert bundle that can be used to verify a server certificate
+    that was signed by one of the authorities in the bundle. curl comes with a
+    default CA cert bundle. You can override the default.
+
+  3.17 How do I list the root dir of an FTP server?
+
+  There are two ways. The way defined in the RFC is to use an encoded slash
+  in the first path part. List the "/tmp" dir like this:
+
+     curl ftp://ftp.sunet.se/%2ftmp/
+
+  or the not-quite-kosher-but-more-readable way, by simply starting the path
+  section of the URL with a slash:
+
+     curl ftp://ftp.sunet.se//tmp/

+
+  * Add an option to the linker command line that specify the hard-coded path

+  5.9 How does libcurl resolve host names?
+
+  libcurl includes a number of different name resolve functions:
+
+  - The non-ipv6 resolver that can use one out of four host name resolve calls
+    (depending on what your system supports):
+
+    A - gethostbyname()
+    B - gethostbyname_r() with 3 arguments
+    C - gethostbyname_r() with 5 arguments
+    D - gethostbyname_r() with 6 arguments
+
+  - The ipv6-resolver that uses getaddrinfo()
+
+  - The c-ares based name resolver that uses the c-ares library for resolves.
+
+  - The Windows threaded resolver. It use:
+
+    A - gethostbyname() on plain ipv4 windows hosts
+    B - getaddrinfo() on ipv6-enabled windows hosts
+
+  Also note that libcurl never resolves or reverse-lookups addresses given as
+  pure numbers, such as 127.0.0.1 or ::1.
+
+  5.10 How do I prevent libcurl from writing the response to stdout?
+
+  libcurl provides a default built-in write function that writes received data
+  to stdout. Set a WRITEFUNCTION to receive the data, or possibly set
+  WRITEDATA to a different FILE * handle.
+
+  5.11 How do I make libcurl not receive the whole HTTP response?
+
+  You make the write callback (or progress callback) return an error and
+  libcurl will then abort the transfer.
+
+  5.12 Can I make libcurl fake or hide my real IP address?
+
+  No. libcurl operates on a higher level than so. Besides, faking IP address
+  would imply sending IP packages with a made-up source address, and then you
+  normally get a problem with intercepting the packages sent back as they
+  would then not be routed to you!
+
+  If you use a proxy to access remote sites, the sites will not see your local
+  IP address but instead the address of the proxy.
+
+  Also note that on many networks NATs or other IP-munging techniques are used
+  that makes you see and use a different IP address locally than what the
+  remote server will see you coming from.

+
+   There are a number of configure options that can be used to reduce the
+   size of libcurl for embedded applications where binary size is an
+   important factor.  First, be sure to set the CFLAGS environment variable
+   when configuring with any compiler optimization flags to reduce the
+   size of the binary.  For gcc, this would mean at minimum:
+
+      env CFLAGS='-Os' ./configure ...
+
+   Be sure to specify as many --disable- and --without- flags on the configure
+   command-line as you can to disable all the libcurl features that you
+   know your application is not going to need.  Besides specifying the
+   --disable-PROTOCOL flags for all the types of URLs your application
+   will not use, here are some other flags that can reduce the size of the
+   library:
+
+     --disable-ares (disables support for the ARES DNS library)
+     --disable-cookies (disables support for HTTP cookies)
+     --disable-crypto-auth (disables HTTP cryptographic authentication)
+     --disable-ipv6 (disables support for IPv6)
+     --disable-verbose (eliminates debugging strings and error code strings)
+     --without-libidn (disables support for the libidn DNS library)
+     --without-ssl (disables support for SSL/TLS)
+     --without-zlib (disables support for on-the-fly decompression)
+
+   You may find that statically linking libcurl to your application will

+21. FTP ASCII transfers do not follow RFC959. They don't convert the data
+   accordingly (not for sending nor for receiving). RFC 959 section 3.1.1.1
+   clearly describes how this should be done:
+
+     The sender converts the data from an internal character representation to
+     the standard 8-bit NVT-ASCII representation (see the Telnet
+     specification).  The receiver will convert the data from the standard
+     form to his own internal form.
+
+20. valgrind errors occur too often when 'make test' is used. It is because
+  too many third-party libs and tools have problems. When curl is built
+  without --disable-shared, the testing is done with a front-end script which
+  makes the valgrind testing include (ba)sh as well and that often causes
+  valgrind errors. Either we improve the valgrind error scanner a lot to
+  better identify (lib)curl errors only, or we disable valgrind checking by
+  default.
+
+19. FTP 3rd party transfers with the multi interface doesn't work. Test:
+  define CURL_MULTIEASY, rebuild curl, run test case 230 - 232.
+
+18. test case 57 has </test> that should be </client> but when corrected, the
+  test case fails!
+
+16. FTP URLs passed to curl may contain NUL (0x00) in the RFC 1738 <user>,
+  <password>, and <fpath> components, encoded as "%00".  The problem is that
+  curl_unescape does not detect this, but instead returns a shortened C
+  string.  From a strict FTP protocol standpoint, NUL is a valid character
+  within RFC 959 <string>, so the way to handle this correctly in curl would
+  be to use a data structure other than a plain C string, one that can handle
+  embedded NUL characters.  From a practical standpoint, most FTP servers
+  would not meaningfully support NUL characters within RFC 959 <string>,
+  anyway (e.g., UNIX pathnames may not contain NUL).
+
+15. Test case 241 fails on all systems that support IPv6 but that don't have
+  the host name 'ip6-localhost' in /etc/hosts (or similar) since the test case
+  uses that host name to test the IPv6 name to address resolver.
+
+14. Test case 165 might fail on system which has libidn present, but with an
+  old iconv version (2.1.3 is a known bad version), since it doesn't recognize
+  the charset when named ISO8859-1. Changing the name to ISO-8859-1 makes the
+  test pass, but instead makes it fail on Solaris hosts that use its native
+  iconv.
+
+13. curl version 7.12.2 fails on AIX if compiled with --enable-ares.
+  The workaround is to combine --enable-ares with --disable-shared
+
+12. When connecting to a SOCKS proxy, the (connect) timeout is not properly
+  acknowledged after the actual TCP connect (during the SOCKS "negotiate"
+  phase). Pointed out by Lucas. Fix: need to select() and timeout properly.
+
+11. Using configure --disable-[protocol] may cause 'make test' to fail for
+  tests using the disabled protocol(s).
+
+10. To get HTTP Negotiate authentication to work fine, you need to provide a
+  (fake) user name (this concerns both curl and the lib) because the code
+  wrongly only considers authentication if there's a user name provided.
+  Bug report #1004841. How? http://curl.haxx.se/mail/lib-2004-08/0182.html
+
+9. --limit-rate using -d or -F does not work. This is because the limit logic
+  is provided by the curl app in its read/write callbacks, and when doing
+  -d/-F the callbacks aren't used! Bug report #921395.
+
+8. Doing resumed upload over HTTP does not work with '-C -', because curl
   doesn't do a HEAD first to get the initial size. This needs to be done
   manually for HTTP PUT resume to work, and then '-C [index]'.

+7. CURLOPT_USERPWD and CURLOPT_PROXYUSERPWD have no way of providing user names
   that contain a colon. This can't be fixed easily in a backwards compatible
   way without adding new options (and then, they should most probably allow
   setting user name and password separately).

   such parts should be sent to the server as 'CWD ' (without an argument).
   The only exception to this rule, is that we knowingly break this if the
   empty part is first in the path, as then we use the double slashes to
   indicate that the user wants to reach the root dir (this exception SHALL
   remain even when this bug is fixed).

+         License Mixing with apps, libcurl and Third Party Libraries
+         ===========================================================
+
+libcurl can be built to use a fair amount of various third party libraries,
+libraries that are written and provided by other parties that are distributed
+using their own licenses. Even libcurl itself contains code that may cause
+problems to some. This document attempts to describe what licenses libcurl and
+the other libraries use and what possible dilemmas linking and mixing them all
+can lead to for end users.
+
+I am not a lawyer and this is not legal advice!
+
+One common dilemma is that GPL[1]-licensed code is not allowed to be linked
+with code licensed under the Original BSD license (with the announcement
+clause, unless there's a specified exception in the GPL-licensed module). You
+may still build your own copies that use them all, but distributing them as
+binaries would be to violate the GPL license - unless you accompany your
+license with an exception[2]. This particular problem was addressed when the
+Modified BSD license was created, which does not have the annoncement clause
+that collides with GPL.
+
+libcurl http://curl.haxx.se/docs/copyright.html
+
+        Uses an MIT (or Modified BSD)-style license that is as liberal as
+        possible.  Some of the source files that deal with KRB4 have Original
+        BSD-style announce-clause licenses. You may not distribute binaries
+        with krb4-enabled libcurl that also link with GPL-licensed code!
+
+OpenSSL http://www.openssl.org/source/license.html
+
+        Uses an Original BSD-style license with an announement clause that
+        makes it "incompatible" with GPL. You are not allowed to ship binaries
+        that link with OpenSSL that includes GPL code (unless that specific
+        GPL code includes an exception for OpenSSL - a habit that is growing
+        more and more common). If OpenSSL's licensing is a problem for you,
+        consider using GnuTLS instead.
+
+GnuTLS  http://www.gnutls.org/
+
+        Uses the LGPL[3] license. If this is a problem for you, consider using
+        OpenSSL instead. Also note that GnuTLS itself depends on and uses
+        other libs (libgcrypt and libgpg-error) and they too are LGPL- or
+        GPL-licensed.
+
+c-ares  http://daniel.haxx.se/projects/c-ares/license.html
+
+        Uses an MIT license that is very liberal and imposes no restrictions
+        on any other library or part you may link with.
+
+zlib    http://www.gzip.org/zlib/zlib_license.html
+
+        Uses an MIT-style license that shouldn't collide with any other
+        library.
+
+krb4
+
+        While nothing in particular says that a Kerberos4 library must use any
+        particular license, the one I've tried and used successfully so far
+        (kth-krb4) is Original BSD-licensed with the announcement clause. Some
+        of the code in libcurl that is written to deal with Kerberos4 likewise
+        have such a license.
+
+GSSAPI
+
+        While nothing in particular says that a GSS/Kerberos5 library must use
+        any particular license, the one I've used (Heimdal) is Original BSD-
+        licensed with the announcement clause.
+
+fbopenssl
+
+        Unclear license. Based on its name, I assume that it uses the OpenSSL
+        license and thus shares the same issues as described for OpenSSL
+        above.
+
+libidn  http://www.gnu.org/licenses/lgpl.html
+
+        Uses the GNU Lesser General Public License. LGPL is a variation of GPL
+        with slightly less aggressive "copyleft". This license requires more
+        requirements to be met when distributing binaries, see the license for
+        details. Also note that if you distribute a binary that includes this
+        library, you must also include the full LGPL license text. Please
+        properly point out what parts of the distributed package that the
+        license addresses.
+
+OpenLDAP http://www.openldap.org/software/release/license.html
+
+        Uses a Modified BSD-style license. Since libcurl uses OpenLDAP as a
+        shared library only, I have not heard of anyone that ships OpenLDAP
+        linked with libcurl in an app.

+
+        curl -d "<xml>" -H "Content-Type: text/xml" -X PROPFIND url.com

+ You can delete a default header by providing one without content. Like you
+ can ruin the request by chopping off the Host: header:
+
+        curl -H "Host:" http://mysite.com
+
+ You can add headers the same way. Your server may want a "Destination:"
+ header, and you can add it:
+
+        curl -H "Destination: http://moo.com/nowhere" http://url.com
+
+13. Debug
+
+ Many times when you run curl on a site, you'll notice that the site doesn't
+ seem to respond the same way to your curl requests as it does to your
+ browser's.
+
+ Then you need to start making your curl requests more similar to your
+ browser's requests:
+
+ * Use the --trace-ascii option to store fully detailed logs of the requests
+   for easier analyzing and better understanding
+
+ * Make sure you check for and use cookies when needed (both reading with -b
+   and writing with -c)
+
+ * Set user-agent to one like a recent popular browser does
+
+ * Set referer like it is set by the browser
+
+ * If you use POST, make sure you send all the fields and in the same order as
+   the browser does it. (See chapter 4.5 above)
+
+ A very good helper to make sure you do this right, is the LiveHTTPHeader tool
+ that lets you view all headers you send and receive with Mozilla/Firefox
+ (even when using HTTPS).
+
+ A more raw approach is to capture the HTTP traffic on the network with tools
+ such as ethereal or tcpdump and check what headers that were sent and
+ received by the browser. (HTTPS makes this technique inefficient.)
