+  Changelog for the c-ares project
+
+* 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
+
+Version 1.2.0 (April 13, 2004)
+
+* April 2, 2004
+- Updated various man pages to look nicer when converted to HTML on the web
+  site.
+
+* April 1, 2004
+- Dirk Manske provided a new function that is now named ares_cancel(). It is
+  used to cancel/cleanup a resolve/request made using ares functions on the
+  given ares channel. It does not destroy/kill the ares channel itself.
+
+- Dominick Meglio cleaned up the formatting in several man pages.
+
+* March 30, 2004
+- Dominick Meglio's new ares_expand_string. A helper function when decoding
+  incoming DNS packages.
+
+- Daniel Stenberg modified the Makefile.in to use a for loop for the man page
+  installation to improve overview and make it easier to add man pages.

+.fi
+.SH DESCRIPTION
+The
+.B ares_expand_string
+function converts a length encoded string to a NULL terminated C
+string.  The argument
+.I encoded
+gives the beginning of the encoded string, and the arguments
+.I abuf
+and
+.I alen
+give the containing message buffer (necessary for the processing of
+indirection pointers within the encoded domain name).  The result is
+placed in a NUL-terminated allocated buffer, a pointer to which is
+stored in the variable pointed to by
+.IR s .
+The length of the encoded string is stored in the variable pointed to by
+.I enclen
+so that the caller can advance past the encoded string to read
+further data in the message.
+.SH RETURN VALUES
+.B ares_expand_string
+can return any of the following values:
+.TP 15
+.B ARES_SUCCESS
+Expansion of the encoded string succeeded.
+.TP 15
+.B ARES_EBADSTR
+The encoded string was malformed and could not be expanded.
+.TP 15
+.B ARES_ENOMEM
+Memory was exhausted.

+  3.16 What certificates do I need when I use SSL?
+
+  There are three different kinds of "certificates" to keep track of when we

+
+  - 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 certficate to make sure that
+    you are truly talking to the real server and not a server impersonating
+    it. The server certificate verifaction 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.

+         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).
+
+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

+    choice.
+
+    To do this, you need to get the CA cert for your server in PEM format and

+
+    If you use Internet Explorer, this is one way to get extract the CA cert
+    for a particular server:
+
+     o View the certificate by double-clicking the padlock
+     o Find out where the CA certificate is kept (Certificate>
+       Authority Information Access>URL)

+       x509 -inform PEM -in certfile -text -out certdata" where certfile is
+       the cert you extracted from logfile. Look in certdata.
+     o If you want to trust the certificate, you can append it to your
+       cert_bundle or use it stand-alone as described. Just remember that the
+       security is no better than the way you obtained the certificate.

+
+    If you're using the curl command line tool on Windows, curl will search
+    for a CA cert file named "curl-ca-bundle.crt" in these directories and in
+    this order:
+      1. application's directory
+      2. current working directory
+      3. Windows System directory (e.g. C:\windows\system32)
