+
+A special thanks to:
+
+ archivas.com and Alan Pinstein, for paying me to focus on their requests
 
 This release includes the following changes:
 
- o allows the URL to be set by a callback when using the multi interface
- o large file support was added. Use one of the new options: INFILESIZE_LARGE,
-   RESUME_FROM_LARGE and MAXFILESIZE_LARGE
- o the new --ftp-pasv overrides a previous --ftpport
- o CURLOPT_FTPSSL and ftps:// now do ssl over FTP "The Right Way" (the curl
-   tool now features the --ftp-ssl option)
- o The Windows DLLs are built with an added "resource file"
- o New LIBCURL_VERSION_* defines for easier checking version number
- o Included Mac OS X 'framework' makefile in the release archive
- o Removed the TRUE and FALSE #defines from the public curl header file
- o Added CURLOPT_NETRC_FILE

+ o added curl_easy_strerror(), curl_multi_strerror() and curl_share_strerror()
+ o IPv6-enabled Windows hosts now resolves names threaded/asynch as well
+ o configure --with-libidn can be used to point out the root dir of a libidn
+   installation (version 0.4.5 or later) for curl to use, then libcurl can
+   resolve and use IDNA names (domain names with "international" letters)
 
 This release includes the following bugfixes:
 
- o improved config file parsing for options with required parameters
- o using --trace with a bad file name could crash
- o release archive contains compressed help text
- o the win32 password prompting supports backspace

- o occational re-use of freed-memory problem fixed
- o curl-config --libs now include the ares link directory
- o configure --enable-ares now accepts a given path
- o -lz no longer appear twice on the link line
- o more descriptive error message if the FTP response reader fails
- o curl-config --feature now shows 'AsynchDNS' when built with ares
- o VMS build up-to-date and clarified source code
- o resolve bug caused socks5 to fail
- o Content-Length: is ignored when getting chunked Transfer-Encoding
- o POST over proxy to https server failed
- o improved how libcurl deals with persistant connections over FTP when a
-   transfer fails

-   text/html"
- o formpost parts now default to "Content-Type: application/octet-stream"
- o --progress-bar was slightly improved
- o Failing to connect to localhost, using the multi interface on Solaris
-   showed a connect problem now fixed.
- o The generated ca-bundle.h file is now generated in the build dir, not the
-   source dir
- o The FTP-EPSV response parser for the 229 code was fixed
- o curl finds the user's home dir slightly different and hopefully better on
-   Windows
- o testcurl.sh can now be used to autotest daily tarballs
- o a couple of command line options now check that the underlying library
-   actually supports the features before trying to enable them
- o uninitialized variable fix
- o better html versions of the man pages
+ o incoming cookies with domains set with a prefixed dot now works better
+ o CURLOPT_COOKIEFILE and CURLOPT_COOKIE can be used in the same request
+ o improved peer certificate name verification
+ o allocation failures cause no leaks nor crashes
+ o the progress meter display now handles file sizes up to full 8 exabytes
+   (which is as high a signed 64 bit number can reach)
+ o general HTTP authentication improvements

-This package is built on ares 1.1.1 (written by Greg Hudson). I've decided to
-put together and release my own ares archives since the ares maintainer
-doesn't want these improvements.
+  Changelog for the c-ares project
 
-The package is called 'c-ares' for now since I (Daniel Stenberg) want this for
-use within the curl project (hence the letter C) and it makes a nice pun.
+* 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.
 
-* January 4, 2004:
+  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.
+
+Version 1.1.0 (March 11, 2004)
+
+* March 9, 2004
+- Gisle Vanem improved build on Windows.
+
+* February 25, 2004
+- Dan Fandrich found a flaw in the Feb 22 fix.
+
+- Added better configure --enable-debug logic (taken from the curl configure
+  script). Added acinclude.m4 to the tarball.
+
+* February 23, 2004
+- Removed ares_free_errmem(), the function, the file and the man page. It was
+  not used and it did nothing.
+
+- Fixed a lot of code that wasn't "64bit clean" and thus caused a lot of
+  compiler warnings on picky compilers.
+
+* February 22, 2004
+- Dominick Meglio made ares init support multiple name servers in the
+  NameServer key on Windows.
+
+* February 16, 2004
+- Modified ares_private.h to include libcurl's memory debug header if
+  CURLDEBUG is set. This makes all the ares-functions supervised properly by
+  the curl test suite. This also forced me to add inclusion of the
+  ares_private.h header in a few more files that are using some kind of
+  memory-related resources.
+
+- Made the makefile only build ahost and adig if 'make demos' is used.
+
+* February 10, 2004
+- Dirk Manske made ares_version.h installed with 'make install'
+
+* February 4, 2004
+- ares_free_errmem() is subject for removal, it is simply present for future
+  purposes, and since we removed the extra parameter in strerror() it won't
+  be used by c-ares!
+- configure --enable-debug now enables picky compiler options if gcc is used
+- fixed several compiler warnings --enable-debug showed and Joerg Mueller-Tolk
+  reported
+
+Version 1.0.0 (February 3, 2004)
+
+* February 3, 2004
+- now we produce the libcares.a library instead of the previous libares.a
+  since we are no longer compatible
+
+* February 2, 2004
+
+- ares_strerror() has one argument less. This is the first official
+  modification of the existing provided ares API.
+
+* January 29, 2004
+
+- Dirk Manske fixed how the socket is set non-blocking.
+
+* January 4, 2004
 
 - Dominick Meglio made the private gettimeofday() become ares_gettimeofday()
   instead in order to not pollute the name space and risk colliding with
   other libraries' versions of this function.

+======
+
+This package is based on ares 1.1.1 (written by Greg Hudson). I decided to
+fork and release a separate project since the ares author didn't want the
+improvements that were vital for our use of it.
+
+This package is dubbed 'c-ares' since I (Daniel Stenberg) wanted this for use
+within the curl project (hence the letter C) and it makes a nice pun. Also,
+c-ares is not API compatible with ares: a new name makes that more obvious to
+the public.
+
+The full source code is available in the 'c-ares' release archives, and in the
+'ares' subdir of the curl CVS source repostitory.
+
+If you find bugs, correct flaws, have questions or have comments in general in
+regard to c-ares (or by all means the original ares too), get in touch with us
+on the c-ares mailing list: http://cool.haxx.se/mailman/listinfo/c-ares
+
+c-ares is of course distributed under the same MIT-style license as the
+original ares.
+
+You'll find all c-ares details and news here:

 .B #include <ares.h>

-.B void ares_free_errmem(char *\fIerrmem\fP)
+.B int ares_cancel(ares_channel \fIchannel\fP)
 .fi
 .SH DESCRIPTION
-The
-.B ares_free_errmem
-function frees any memory which might have been allocated by the
-.BR ares_strerror (3)
-function.  The parameter
-.I errmem
-should be set to the variable pointed to by the
-.I memptr
-argument previously passed to
-.IR ares_strerror .
+The \fBares_cancel\fP function cancels all lookups/requests made on the the
+name service channel identified by \fIchannel\fP.  \fBares_cancel\fP invokes
+the callbacks for each pending query on the channel, passing a status of
+.BR ARES_ETIMEOUT .
+These calls give the callbacks a chance to clean up any state which
+might have been stored in their arguments.

+.SH NAME
+ares_expand_string \- Expand a length encoded string
+.SH SYNOPSIS
+.nf
+.B #include <ares.h>
+.PP
+.B int ares_expand_string(const unsigned char *\fIencoded\fP,
+.B      const unsigned char *\fIabuf\fP, int \fIalen\fP, unsigned char **\fIs\fP,
+.B 	int *\fIenclen\fP)
+.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.

+.PP
+.B const char *ares_version(int *\fIversion\fP)
+.fi
+.SH DESCRIPTION
+The
+.B ares_version
+function gets the library version as a string and optionally as an integer
+stored in the
+.IR version ,
+argument. If you pass a NULL, no integer is attempted to be returned.
+
+The integer is built up as 24bit number, with 8 separate bits used for major
+number, minor number and patch number. This makes a version string such as
+1.2.3 will be returned as the hexadecimal number 0x010203 (decimal 66051).
+.SH NOTES
+This function is not compatible with ares.

-There is a glitch / trick to using cURL on Win32 related to re-entrancy.
-This experience was gained on verion 7.9.4 using Windows NT SP3 in a banking
-environment (just in case you wanted to know).
-
-If you have already called curl_easy_perform(), and *somehow* you cause your
-single thread of execution to make another call to curl_easy_perform() - the
-windows socket() call used to create a new socket for the second connection
-can return with 10044 / 10043 error codes.
-
-The WSA errors we experienced are:
-WSAEPROTONOSUPPORT 
-(10043) 
-Protocol not supported. 
-The requested protocol has not been configured into the system, or no
-implementation for it exists. For example, a socket call requests a
-SOCK_DGRAM socket, but specifies a stream protocol. 
-
-WSAESOCKTNOSUPPORT 
-(10044) 
-Socket type not supported. 
-The support for the specified socket type does not exist in this address
-family. For example, the optional type SOCK_RAW might be selected in a
-socket call, and the implementation does not support SOCK_RAW sockets at
-all. 
-
-We have experienced this by creating a timer that ticks every 20ms, and on
-the tick making a curl_easy_perform() call.  The call usually completed in
-about 300ms.  And we expected (before this test) that the timer would NOT be
-fired during a call to curl_easy_perform(), howvever, while the first
-curl_easy_perform() is running a tick *is* fired by the windows API somehow,
-and we then call curl_easy_perform() again - thus single threaded
-re-entrancy is achieved.
-
-Notes:
-* We made sure that a new CURL structure was being used for each
-curl_easy_perform() request, and that the curl_global_init() had been called
-beforehand.  
-* I'm happy to answer any questions about this problem to try to track it
-down.
-* Once the socket() call started failing, there is no hope - it never works
-again.
-* Slowing the timer down to give each request enough time to complete solves
-this problem completely.
-
-If anyone has the source code to the WinNT implementation of socket() and
-can figure out WHY this can occur, more tracing can be performed.

+         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[*]-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. 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
+        shared library only, I have not heard of anyone that ships OpenLDAP
+        linked with libcurl in an app.
