   Changelog for the c-ares project
 
+* October 12 2006
+
+- Prevent ares_getsock() to overflow if more than 16 sockets are used.
+
+* September 11 2006
+
+- Guilherme Balena Versiani: I noted a strange BUG in Win32 port
+  (ares_init.c/get_iphlpapi_dns_info() function): when I disable the network
+  by hand or disconnect the network cable in Windows 2000 or Windows XP, my
+  application gets 127.0.0.1 as the only name server. The problem comes from
+  'GetNetworkParams' function, that returns the empty string "" as the only
+  name server in that case. Moreover, the Windows implementation of
+  inet_addr() returns INADDR_LOOPBACK instead of INADDR_NONE.
+
+* August 29 2006
+
+- Brad Spencer did
+
+  o made ares_version.h use extern "C" for c++ compilers
+  o fixed compiler warnings in ares_getnameinfo.c
+  o fixed a buffer position init for TCP reads
+
+* August 3 2006
+
+- Ravi Pratap fixed ares_getsock() to actually return the proper bitmap and
+  not always zero!
+
+Version 1.3.1 (June 24, 2006)
+
+* July 23, 2006
+
+- Gisle Vanem added getopt() to the ahost program. Currently accepts
+  only [-t {a|aaaa}] to specify address family in ares_gethostbyname().
+
+* June 19, 2006
+
+- (wahern) Removed "big endian" DNS section and RR data integer parser
+  macros from ares_dns.h, which break c-ares on my Sparc64. Bit-wise
+  operations in C operate on logical values. And in any event the octets are
+  already in big-endian (aka network) byte order so they're being reversed
+  (thus the source of the breakage).
+
+* June 18, 2006
+
+- William Ahern handles EAGAIN/EWOULDBLOCK errors in most of the I/O calls
+  from area_process.c.
+
+  TODO: Handle one last EAGAIN for a UDP socket send(2) in
+  ares__send_query().
+
+* May 10, 2006
+
+- Bram Matthys brought my attention to a libtool peculiarity where detecting
+  things such as C++ compiler actually is a bad thing and since we don't need
+  that detection I added a work-around, much inspired by a previous patch by
+  Paolo Bonzini. This also shortens the configure script quite a lot.
+
+* May 3, 2006
+
+- Nick Mathewson added the ARES_OPT_SOCK_STATE_CB option that when set makes
+  c-ares call a callback on socket state changes. A better way than the
+  ares_getsock() to get full control over the socket state.
+

+eCos
+====
+   curl does not use the eCos build system, so you must first build eCos
+   separately, then link curl to the resulting eCos library.  Here's a sample
+   configure line to do so on an x86 Linux box targeting x86:
+
+   GCCLIB=`gcc -print-libgcc-file-name` && \
+   CFLAGS="-D__ECOS=1 -nostdinc -I$ECOS_INSTALL/include \
+    -I`dirname $GCCLIB`/include" \
+   LDFLAGS="-nostdlib -Wl,--gc-sections -Wl,-static \
+    -L$ECOS_INSTALL/lib -Ttarget.ld -ltarget" \
+   ./configure --host=i386 --disable-shared \
+    --without-ssl --without-zlib --disable-manual --disable-ldap
+
+   In most cases, eCos users will be using libcurl from within a custom
+   embedded application.  Using the standard 'curl' executable from
+   within eCos means facing the limitation of the standard eCos C
+   startup code which does not allow passing arguments in main().  To
+   run 'curl' from eCos and have it do something useful, you will need
+   to either modify the eCos startup code to pass in some arguments, or
+   modify the curl application itself to retrieve its arguments from
+   some location set by the bootloader or hard-code them.
+
+   Something like the following patch could be used to hard-code some
+   arguments.  The MTAB_ENTRY line mounts a RAM disk as the root filesystem
+   (without mounting some kind of filesystem, eCos errors out all file
+   operations which curl does not take to well).  The next section synthesizes
+   some command-line arguments for curl to use, in this case to direct curl
+   to read further arguments from a file.  It then creates that file on the
+   RAM disk and places within it a URL to download: a file: URL that
+   just happens to point to the configuration file itself.  The results
+   of running curl in this way is the contents of the configuration file
+   printed to the console.

+  instead of just printed to stdout, you need to add one save option for each
+  URL you specify. Note that this also goes for the -O option.
+
+  For example: get two files and use -O for the first and a custom file
+  name for the second:
+
+    curl -O http://url.com/file.txt ftp://ftp.com/moo.exe -o moo.jpg
+
+  You can also upload multiple files in a similar fashion:

+
+Requires glib-2.x and a (POSIX?) system that has mkfifo().
+
+This is an adaptation of libcurl's "hipev.c" and libevent's "event-test.c"
+sample programs, adapted to use glib's g_io_channel in place of libevent.
+
+When running, the program creates the named pipe "hiper.fifo"
+
+Whenever there is input into the fifo, the program reads the input as a list
+of URL's and creates some new easy handles to fetch each URL via the
+curl_multi "hiper" API.
+
+
+Thus, you can try a single URL:
+  % echo http://www.yahoo.com > hiper.fifo
+
+Or a whole bunch of them:
+  % cat my-url-list > hiper.fifo
+
+The fifo buffer is handled almost instantly, so you can even add more URL's
+while the previous requests are still being downloaded.
+
+This is purely a demo app, all retrieved data is simply discarded by the write
+callback.

+ * Example application source code using the multi socket interface to
+ * download many files at once.
+ *
+ * Written by Jeff Pohlmeyer
+
+Requires libevent and a (POSIX?) system that has mkfifo().
+
+This is an adaptation of libcurl's "hipev.c" and libevent's "event-test.c"
+sample programs.
+
+When running, the program creates the named pipe "hiper.fifo"
+
+Whenever there is input into the fifo, the program reads the input as a list
+of URL's and creates some new easy handles to fetch each URL via the
+curl_multi "hiper" API.
+
+
+Thus, you can try a single URL:
+  % echo http://www.yahoo.com > hiper.fifo
+
+Or a whole bunch of them:
+  % cat my-url-list > hiper.fifo
+
+The fifo buffer is handled almost instantly, so you can even add more URL's
+while the previous requests are still being downloaded.
+
+Note:
+  For the sake of simplicity, URL length is limited to 1023 char's !
+
+This is purely a demo app, all retrieved data is simply discarded by the write
+callback.

+This function converts the given input string to an URL encoded string and
