+# Google Android makefile for curl and libcurl
+#
+# Place the curl source (including this makefile) into external/curl/ in the
+# Android source tree.  Then build them with 'make curl' or just 'make libcurl'
+# from the Android root. Tested with Android 1.5
+#
+# Note: you must first create a curl_config.h file by running configure in the
+# Android environment. The only way I've found to do this is tricky. Perform a
+# normal Android build with libcurl in the source tree, providing the target
+# "showcommands" to make. The build will eventually fail (because curl_config.h
+# doesn't exist yet), but the compiler commands used to build curl will be
+# shown. Now, from the external/curl/ directory, run curl's normal configure
+# command with flags that match what Android itself uses. This will mean
+# putting the compiler directory into the PATH, putting the -I, -isystem and
+# -D options into CPPFLAGS, putting the -m, -f, -O and -nostdlib options into
+# CFLAGS, and putting the -Wl, -L and -l options into LIBS, along with the path
+# to the files libgcc.a, crtbegin_dynamic.o, and ccrtend_android.o. Remember
+# that the paths must be absolute since you will not be running configure from
+# the same directory as the Android make.  The normal cross-compiler options
+# must also be set.
+#
+# The end result will be a configure command that looks something like this
+# (the environment variable A is set to the Android root path):
+#
+#  A=`realpath ../..` && \
+#  PATH="$A/prebuilt/linux-x86/toolchain/arm-eabi-X/bin:$PATH" \

                                   Changelog
 
+Version 7.19.7 (4 November 2009)
+
+Daniel Stenberg (2 Nov 2009)
+- As reported independent by both Stan van de Burgt and Didier Brisebourg,
+  CURLINFO_SIZE_DOWNLOAD (the -w variable size_download) didn't work when
+  getting data from ldap!
+
+Daniel Stenberg (31 Oct 2009)
+- Gabriel Kuri reported a problem with CURLINFO_CONTENT_LENGTH_DOWNLOAD if the
+  download was 0 bytes, as libcurl would then return the size as unknown (-1)
+  and not 0. I wrote a fix and test case 566 to verify it.
+
+Daniel Stenberg (30 Oct 2009)
+- Liza Alenchery mentioned a problem with re-used SCP connection when a bad
+  auth is used, as it caused a crash. I failed to repeat the issue, but still
+  made a change that now forces the TCP connection used for a freed SCP
+  session to get closed and not be re-used.
+
+- "Tom" posted a bug report that mentioned how libcurl did wrong when doing a
+  POST using a read callback, with Digest authentication and
+  "Transfer-Encoding: chunked" enforced.  I would then cause the first request
+  to be wrongly sent and then basically hang until the server closed the
+  connection. I fixed the problem and added test case 565 to verify it.
+
+Daniel Stenberg (25 Oct 2009)
+- Dima Barsky made the curl cookie parser accept cookies even with blank or
+  unparsable expiry dates and then treat them as session cookies - previously
+  libcurl would reject cookies with a date format it couldn't parse. Research
+  shows that the major browser treat such cookies as session cookies. I
+  modified test 8 and 31 to verify this.
+
+Daniel Stenberg (21 Oct 2009)
+- Attempt to use pkg-config for finding out libssh2 installation details
+  during configure.
+
+- A patch in bug report #2883177 (http://curl.haxx.se/bug/view.cgi?id=2883177)
+  by Johan van Selst introduced the --crlfile option to curl, which makes curl
+  tell libcurl about a file with CRL (certificate revocation list) data to
+  read.
+
+Daniel Stenberg (18 Oct 2009)
+- Ray Dassen provided a patch in Debian's bug tracker (bug number #551461)
+  that now makes curl_getdate(3) actually handles RFC 822 formatted dates that
+  use the "single letter military timezones".
+  http://www.rfc-ref.org/RFC-TEXTS/822/chapter5.html has the details.
+
+- Fixed memory leak in the SCP/SFTP code as it never freed the knownhosts
+  data!
+
+- John Dennis filed bug report #2873666
+  (http://curl.haxx.se/bug/view.cgi?id=2873666) which identified a problem
+  which made libcurl loop infinitely when given incorrect credentials when
+  using HTTP GSS negotiate authentication. He also provided a small and simple
+  patch for it.
+
+- Kevin Baughman found a double close() problem with libcurl-NSS, as when
+  libcurl called NSS to close the SSL "session" it also closed the actual
+  socket.
+
+Yang Tse (17 Oct 2009)
+- Bug report #2866724 indicated
+  (http://curl.haxx.se/bug/view.cgi?id=2866724) that curl on Windows failed
+  when writing files whose file names originally contained characters which
+  are not valid for file names on Windows. Dan Fandrich provided an initial
+  patch and another revised one to fix this issue.
+
+Daniel Stenberg (1 Oct 2009)
+- Tom Mueller correctly reported in bug report #2870221
+  (http://curl.haxx.se/bug/view.cgi?id=2870221) that libcurl returned an
+  incorrect return code from the internal trynextip() function which caused
+  him grief. This is a regression that was introduced in 7.19.1 and I find it
+  strange it hasn't hit us harder, but I won't persue into figuring out
+  exactly why.
+ 
+- Constantine Sapuntzakis: The current implementation will always set
+  SO_SNDBUF to CURL_WRITE_SIZE even if the SO_SNDBUF starts out larger.  The
+  patch doesn't do a setsockopt if SO_SNDBUF is already greater than
+  CURL_WRITE_SIZE. This should help folks who have set up their computer with
+  large send buffers.
+
+Daniel Stenberg (27 Sep 2009)
+- I introduced a maximum limit for received HTTP headers. It is controlled by
+  the define CURL_MAX_HTTP_HEADER which is even exposed in the public header
+  file to allow for users to fairly easy rebuild libcurl with a modified
+  limit. The rationale for a fixed limit is that libcurl is realloc()ing a
+  buffer to be able to put a full header into it, so that it can call the
+  header callback with the entire header, but that also risk getting it into
+  trouble if a server by mistake or willingly sends a header that is more or
+  less without an end. The limit is set to 100K.
+
+Daniel Stenberg (26 Sep 2009)
+- John P. McCaskey posted a bug report that showed how libcurl did wrong when
+  saving received cookies with no given path, if the path in the request had a
+  query part. That is means a question mark (?) and characters on the right
+  side of that. I wrote test case 1105 and fixed this problem.
+
+Kamil Dudka (26 Sep 2009)
+- Implemented a protocol independent way to specify blocking direction, used by
+  transfer.c for blocking. It is currently used only by SCP and SFTP protocols.
+  This enhancement resolves an issue with 100% CPU usage during SFTP upload,
+  reported by Vourhey.
+
+Daniel Stenberg (25 Sep 2009)
+- Chris Mumford filed bug report #2861587
+  (http://curl.haxx.se/bug/view.cgi?id=2861587) identifying that libcurl used
+  the OpenSSL function X509_load_crl_file() wrongly and failed if it would
+  load a CRL file with more than one certificate within. This is now fixed.
+  
+Daniel Stenberg (16 Sep 2009)
+- Sven Anders reported that we introduced a cert verfication flaw for OpenSSL-
+  powered libcurl in 7.19.6. If there was a X509v3 Subject Alternative Name
+  field in the certficate it had to match and so even if non-DNS and non-IP
+  entry was present it caused the verification to fail.
+
+Daniel Fandrich (15 Sep 2009)
+- Moved the libssh2 checks after the SSL library checks. This helps when
+  statically linking since libssh2 needs the SSL library link flags to be
+  set up already to satisfy its dependencies. This wouldn't be necessary if
+  the libssh2 configure check was changed to use pkg-config since the
+  --static flag would add the dependencies automatically.
+
+Yang Tse (14 Sep 2009)
+- Revert Joshua Kwan's patch committed 11 Sep 2009.
+
+  Some systems poll function sets POLLHUP in revents without setting
+  POLLIN, and sets POLLERR without setting POLLIN and POLLOUT. In some
+  libcurl code execution paths this could trigger busy wait loops with
+  high CPU usage until a timeout condition aborted the loop.
+
+  The reverted patch addressed the above issue for a very specific case,
+  when awaiting c-ares to resolve. A libcurl-wide fix for Curl_poll now
+  superceeds this one.
+
+Guenter Knauf (11 Sep 2009)
+- Joshua Kwan provided a patch to pass POLLERR / POLLHUP back to c-ares.
+  This fixes a loop problem with high CPU usage.
+
+Daniel Stenberg (10 Sep 2009)
+- Claes Jakobsson fixed a problem with cookie expiry dates at exctly the epoch
+  start second "Thu Jan 1 00:00:00 GMT 1970" as the date parser then returns 0
+  which internally then is treated as a session cookie. That particular date
+  is now made to get the value of 1.
+
+Daniel Stenberg (2 Sep 2009)
+- Daniel Johnson found a flaw in the code converting sftp-errors to libcurl
+  errors.
+
+Daniel Stenberg (1 Sep 2009)
+- Peter Sylvester made a debug feature for Curl_resolv() that now will force
+  libcurl to resolve 'localhost' whatever name you use in the URL *if* you set
+  the --interface option to (exactly) "LocalHost". This will enable us to
+  write tests for custom hosts names but still use a local host server.
+
+- configure now tries to use pkg-config for a number of sub-dependencies even
+  when cross-compiling. The key to success is then you properly setup
+  PKG_CONFIG_PATH before invoking configure.
+
+  I also improved how NSS is detected by trying nss-config if pkg-config isn't
+  present, and as a last resort just use the lib name and force the user to
+  setup the LIBS/LDFLAGS/CFLAGS etc properly. The previous last resort would
+  add a range of various libs that would almost never be quite correct.
+
+Daniel Stenberg (31 Aug 2009)
+- When using the multi interface with FTP and you asked for NOBODY, you did no
+  QUOTE commands and the request used the same path as the connection had
+  already changed to, it would decide that no commands would be necessary for
+  the "DO" action and that was not handled properly but libcurl would instead
+  hang.
+
+Kamil Dudka (28 Aug 2009)
+- Improved error message for not matching certificate subject name in
+  libcurl-NSS. Originally reported at:
+  https://bugzilla.redhat.com/show_bug.cgi?id=516056#c9
+
+Patrick Monnerat (24 Aug 2009)
+- Introduced a SYST-based test to properly set-up name format when dealing
+  with the OS/400 FTP server.
+
+- Fixed an ftp_readresp() bug preventing detection of failing control socket
+  and causing FTP client to loop forever.
+
+Daniel Stenberg (24 Aug 2009)
+- Marc de Bruin pointed out that configure --with-gnutls=PATH didn't work
+  properly and provided a fix. http://curl.haxx.se/bug/view.cgi?id=2843008
+
+- Eric Wong introduced support for the new option -T. (dot) that makes curl
+  read stdin in a non-blocking fashion. This also brings back -T- (minus) to
+  the previous blocking behavior since it could break stuff for people at
+  times.
+
+Michal Marek (21 Aug 2009)
+- With CURLOPT_PROXY_TRANSFER_MODE, avoid sending invalid URLs like
+  ftp://example.com;type=i if the user specified ftp://example.com without the
+  slash.
+
+Daniel Stenberg (21 Aug 2009)
+- Andre Guibert de Bruet pointed out a missing return code check for a
+  strdup() that could lead to segfault if it returned NULL. I extended his
+  suggest patch to now have Curl_retry_request() return a regular return code
+  and better check that.
+
+- Lots of good work by Krister Johansen, mostly related to pipelining:
+
+  Fix SIGSEGV on free'd easy_conn when pipe unexpectedly breaks
+  Fix data corruption issue with re-connected transfers
+  Fix use after free if we're completed but easy_conn not NULL
+
+Kamil Dudka (13 Aug 2009)
+- Changed NSS code to not ignore the value of ssl.verifyhost and produce more
+  verbose error messages. Originally reported at:
+  https://bugzilla.redhat.com/show_bug.cgi?id=516056
+
+Daniel Stenberg (12 Aug 2009)
+- Karl Moerder fixed the Makefile.vc* makefiles to include the new file
+  nonblock.c so that they work fine again
+
+- I expanded test 517 with a bunch of more dates that originate from the
+  Chrome browser test suite. It turns out most of them get parsed the same
+  way.
+
+Version 7.19.6 (12 August 2009)
+
+Daniel Stenberg (12 Aug 2009)
+- Carsten Lange reported a bug and provided a patch for TFTP upload and the
+  sending of the TSIZE option. I don't like fixing bugs just hours before
+  a release, but since it was broken and the patch fixes this for him I decided
+  to get it in anyway.
+
+Daniel Stenberg (11 Aug 2009)
+- Peter Sylvester made the HTTPS test server use specific certificates for
+  each test, so that the test suite can now be used to actually test the
+  verification of cert names etc. This made an error show up in the OpenSSL-
+  specific code where it would attempt to match the CN field even if a
+  subjectAltName exists that doesn't match. This is now fixed and verified
+  in test 311.
+
+- Benbuck Nason posted the bug report #2835196
+  (http://curl.haxx.se/bug/view.cgi?id=2835196), fixing a few compiler
+  warnings when mixing ints and bools.
+
+Daniel Fandrich (10 Aug 2009)
+- Fixed a memory leak in the FTP code and an off-by-one heap buffer overflow.
+
+Daniel Fandrich (9 Aug 2009)
+- Fixed some memory leaks in the command-line tool that caused most of the
+  torture tests to fail.
+
+Daniel Stenberg (2 Aug 2009)
+- Curt Bogmine reported a problem with SNI enabled on a particular server. We
+  should introduce an option to disable SNI, but as we're in feature freeze
+  now I've addressed the obvious bug here (pointed out by Peter Sylvester): we
+  shouldn't try to enable SNI when SSLv2 or SSLv3 is explicitly selected.
+  Code for OpenSSL and GnuTLS was fixed. NSS doesn't seem to have a particular
+  option for SNI, or are we simply not using it?
+
+Daniel Stenberg (1 Aug 2009)
+- Scott Cantor posted the bug report #2829955
+  (http://curl.haxx.se/bug/view.cgi?id=2829955) mentioning the recent SSL cert
+  verification flaw found and exploited by Moxie Marlinspike. The presentation
+  he did at Black Hat is available here:
+  https://www.blackhat.com/html/bh-usa-09/bh-usa-09-archives.html#Marlinspike
+
+  Apparently at least one CA allowed a subjectAltName or CN that contain a
+  zero byte, and thus clients that assumed they would never have zero bytes
+  were exploited to OK a certificate that didn't actually match the site. Like
+  if the name in the cert was "example.com\0theatualsite.com", libcurl would
+  happily verify that cert for example.com.
+
+  libcurl now better uses the length of the extracted name, not using the zero
+  termination for getting the string length.
+
+  This fixing only made and needed in OpenSSL interfacing code.
+
+- Tanguy Fautre pointed out that OpenSSL's function RAND_screen() (present
+  only in some OpenSSL installs - like on Windows) isn't thread-safe and we
+  agreed that moving it to the global_init() function is a decent way to deal
+  with this situation.
+
+- Alexander Beedie provided the patch for a noproxy problem: If I have set
+  CURLOPT_NOPROXY to "*", or to a host that should not use a proxy, I actually
+  could still end up using a proxy if a proxy environment variable was set.
+
+Daniel Stenberg (27 Jul 2009)
+- All the quote options (CURLOPT_QUOTE, CURLOPT_POSTQUOTE and
+  CURLOPT_PREQUOTE) now accept a preceeding asterisk before the command to
+  send when using FTP, as a sign that libcurl shall simply ignore the response
+  from the server instead of treating it as an error. Not treating a 400+ FTP
+  response code as an error means that failed commands will not abort the
+  chain of commands, nor will they cause the connection to get disconnected.
+
+Daniel Stenberg (26 Jul 2009)
+- Johan van Selst posted bug report #2825989
+  (http://curl.haxx.se/bug/view.cgi?id=2825989) pointing out that
+  OpenSSL-powered libcurl didn't support the SHA-2 digest algorithm, and
+  provided the solution too: to use OpenSSL_add_all_algorithms() in addition
+  to the older SSLeay_* alternative. OpenSSL_add_all_algorithms was added in
+  OpenSSL 0.9.5
+
+Daniel Stenberg (23 Jul 2009)
+- Added CURLOPT_SSH_KNOWNHOSTS, CURLOPT_SSH_KEYFUNCTION, CURLOPT_SSH_KEYDATA.
+  They introduce known_host support for SSH keys to libcurl. See docs for
+  details. Note that this feature depends on a new enough libssh2 version, to
+  be supported in libssh2 1.2 and later (or current git repo at this time).
+
+Michal Marek (22 Jul 2009)
+- David Binderman found a memory and fd leak in lib/gtls.c:load_file()
+  (https://bugzilla.novell.com/523919). When looking at the code, I found that
+  also the ptr pointer can leak.
+
+Kamil Dudka (20 Jul 2009)
+- Claes Jakobsson improved the support for client certificates handling in
+  NSS-powered libcurl. Now the client certificates can be selected
+  automatically by a NSS built-in hook. Additionally pre-login to all PKCS11
+  slots is no more performed. It used to cause problems with HW tokens.
+
+- Fixed reference counting for NSS client certificates. Now the PEM reader
+  module should be always properly unloaded on Curl_nss_cleanup(). If the
+  unload fails though, libcurl will try to reuse the already loaded instance.
+
+Daniel Fandrich (15 Jul 2009)
+- Added nonblock.c to the non-automake makefiles (note that the dependencies
+  in the Watcom makefiles aren't quite correct).
+
+Michal Marek (15 Jul 2009)
+- Changed the description of CURLINFO_OS_ERRNO to make it clear that the
+  errno is not reset on success.
+
+Guenter Knauf (14 Jul 2009)
+- renamed generated config.h to curl_config.h to avoid any future clashes
+  with config.h from other projects.
+  
+Daniel Stenberg (9 Jul 2009)
+- Eric Wong introduced curlx_nonblock() that the curl tool now (re-)uses for
+  setting a file descriptor non-blocking. Used by the functionality Eric
+  himself brough on June 15th.
+
+Daniel Stenberg (8 Jul 2009)
+- Constantine Sapuntzakis posted bug report #2813123
+  (http://curl.haxx.se/bug/view.cgi?id=2813123) and an a patch that fixes the
+  problem:
+
+  Url A is accessed using auth. Url A redirects to Url B (on a different
+  server0. Url B reuses a persistent connection. Url B has auth, even though
+  it's on a different server.
+
+  Note: if Url B does not reuse a persistent connection, auth is not sent.
+
+  reason:
+
+  data->state.first_host is not initialized becuase Curl_http_connect is not
+  called when a connection is reused.
+
+  Solution:
+
+  move initialization of data->state.first_host to Curl_http. No code before
+  Curl_http uses data->state.first_host anyway.
+
+Guenter Knauf (4 Jul 2009)
+- Markus Koetter provided a patch to avoid getnameinfo() usage which broke a
+  couple of both IPv4 and IPv6 autobuilds.
+
+Daniel Stenberg (29 Jun 2009)
+- Markus Koetter made CURLOPT_FTPPORT (and curl's -P/--ftpport) support a port
+  range if given colon-separated after the host name/address part. Like
+  "192.168.0.1:2000-10000"
+
+- Modified the separators used for CURLOPT_CERTINFO in multi-part outputs. I
+  don't know how they got wrong in the first place, but using this output
+  format makes it possible to quite easily separate the string into an array
+  of multiple items.
+
+Daniel Fandrich (16 June 2009)
+- Added a few more compiler warning options for gcc.
+
+Daniel Stenberg (16 Jun 2009)
+- Reuven Wachtfogel made curl -o - properly produce a binary output on windows
+  (no newline translations). Use -B/--use-ascii if you rather get the ascii
+  approach.
+
+Michal Marek (16 Jun 2009)
+- When doing non-anonymous ftp via http proxies and the password is not
+  provided in the url, add it there (squid needs this).
+
+Daniel Stenberg (15 Jun 2009)
+- Eric Wong's patch:
+
+  This allows curl(1) to be used as a client-side tunnel for arbitrary stream
+  protocols by abusing chunked transfer encoding in both the HTTP request and
+  HTTP response.  This requires server support for sending a response while a
+  request is still being read, of course.
+
+  If attempting to read from stdin returns EAGAIN, then we pause our sender.
+  This leaves curl to attempt to read from the socket while reading from stdin
+  (and thus sending) is paused.
+
+  This change was needed to allow successfully tunneling the git protocol over
+  HTTP (--no-buffer is needed, as well).
+
+Patrick Monnerat (15 Jun 2009)
+- Replaced use of standard C library rand()/srand() by our own pseudo-random
+  number generator.
+
+Yang Tse (11 Jun 2009)
+- I adapted testcurl script to allow building test harness programs when
+  cross-compiling for a *-*-mingw* host.
+
+Daniel Stenberg (10 Jun 2009)
+- Fabian Keil ran clang on the (lib)curl code, found a bunch of warnings and
+  contributed a range of patches to fix them.
+
+Yang Tse (10 Jun 2009)
+- I introduced configure script option --enable-curldebug which now allows
+  the decoupled enabling or disabling of the curl debug memory tracking
+  feature from the --enable-debug option which no longer controls this.
+
+  curl --version will list 'Debug' feature for debug enabled builds, and
+  will list 'TrackMemory' feature for curl debug memory tracking capable
+  builds. These features are independent and can be controlled when running
+  the configure script. When --enable-debug is given both features will be
+  enabled, unless some restriction prevents memory tracking from being used.
+
+  Internally, definition of preprocessor symbol DEBUGBUILD restricts code
+  which is only compiled for debug enabled builds. And symbol CURLDEBUG is
+  used to differentiate code which is _only_ used for memory tracking.
+
+Yang Tse (9 Jun 2009)
+- Daniel Steinberg pointed out that Curl_FormInit() in formdata.c was not
+  initializing the fread callback pointer and this triggered a compiler
+  warning, also provided a friendly suggestion on how to fix it.
+
+Daniel Stenberg (8 Jun 2009)
+- Claes Jakobsson provided a patch for libcurl-NSS that fixed a bad refcount
+  issue with client certs that caused issues like segfaults.
+  http://curl.haxx.se/mail/lib-2009-05/0316.html
+
+- Triggered by bug report #2798852 and the patch in there, I fixed configure
+  to detect gnutls build options with pkg-config only and not libgnutls-config
+  anymore since GnuTLS has stopped distributing that tool. If an explicit path
+  is given to configure, we will instead guess on how to link and use that
+  lib. I did not use the patch from the bug report.
+
+Yang Tse (8 Jun 2009)
+- Igor Novoseltsev adjusted Makefile.vxworks to get sources and headers
+  included from Makefile.inc, and provided docs\INSTALL VxWorks section.
+
+- I removed buildconf.bat from release and daily snapshot archives. This
+  file is only for CVS tree checkout builds.
+
+Daniel Stenberg (8 Jun 2009)
+- Eric Wong fixed --no-buffer to actually switch off output buffering. Been
+  broken since 7.19.0
+
+Bill Hoffman (6 Jun 2009)
+- Added some cmake docs and fixed socklen_t in the build.
+
+Yang Tse (5 Jun 2009)
+- John E. Malmberg provided VMS specific patch: "This fixes an existing bug
+  in urlglob.c where it was not converting the Curl Unix exit code to a VMS
+  DCL compatible exit code.  This fix required the enhancement described next.
+  This also adds an enhancement to main.c so that when curl is run under a
+  Unix shell like Bash on VMS, it will return the standard Unix exit codes
+  and messages." And another patch for docs/examples.
+
+  I introduced os-specific.c and os-specific.h for use in curl tool code
+  and adjusted John E. Malmberg's patch placement to use these new files
+  as an effort to prevent main.c from growing ad infinitum. Code already
+  existing in main.c which is OS specific should be moved into these files.

+- Setting the Content-Length: header from your app when you do a POST or PUT
+  is almost always a VERY BAD IDEA. Yet there are still apps out there doing
+  this, and now recently it triggered a bug/side-effect in libcurl as when
+  libcurl sends a POST or PUT with NTLM, it sends an empty post first when it
+  knows it will just get a 401/407 back. If the app then replaced the
+  Content-Length header, it caused the server to wait for input that libcurl
+  wouldn't send. Aaron Oneal reported this problem in bug report #2799008
+  (http://curl.haxx.se/bug/view.cgi?id=2799008) and helped us verify the fix.
+
+Yang Tse (4 Jun 2009)
+- Igor Novoseltsev provided patches and information, that after some
+  adjustments to better fit curl's way of doing things, have resulted
+  in the posibility of building libcurl for VxWorks.
+
+Daniel Fandrich (2 June 2009)
+- Checked in a Google Android make file. To use it, you must first
+  create a config.h file by running configure in the Android environment,
+  which doesn't seem to be easy to do. If no easy way can be found, a
+  static config-android.h may need to be created and checked in to the
+  libcurl source tree.
+
+Daniel Stenberg (1 June 2009)
+- Claes Jakobsson fixed the configure script to better find and use NSS
+  without pkg-config.
+
+Yang Tse (1 Jun 2009)
+- John E. Malmberg provided a VMS specific clean-up for curl.h, and pointed
+  out that the configure script was failing to detect the timeval struct on
+  VMS when building with _XOPEN_SOURCE_EXTENDED undefined due to definition
+  taking place in socket.h instead of time.h.  I have adjusted configure
+  script to also include this header when checking struct timeval.
+
+Daniel Stenberg (27 May 2009)
+- Frank McGeough provided a small OpenSSL #include fix to make libcurl compile
+  fine with Nokia 5th edition 1.0 SDK for Symbian.
+
+- Andre Guibert de Bruet found a call to a OpenSSL function that didn't check
+  for a failure properly.
+
+- Mike Crowe pointed out that setting CURLOPT_USERPWD to NULL used to clear
+  the auth credentials back in 7.19.0 and earlier while now you have to set ""
+  to get the same effect. His patch brings back the ability to use NULL.
+
+- Claes Jakobsson fixed libcurl-NSS to build fine even without the
+  PK11_CreateGenericObject() function.
+
+Daniel Stenberg (25 May 2009)
+- bug report #2796358 (http://curl.haxx.se/bug/view.cgi?id=2796358) pointed
+  out that the cookie parser would leak memory when it parses cookies that are
+  received with domain, path etc set multiple times in the same header. While
+  such a cookie is questionable, they occur in the wild and libcurl no longer
+  leaks memory for them. I added such a header to test case 8.
+
+Daniel Fandrich (22 May 2009)
+- Removed some obsolete digest code that caused a valgrind error in test 551.
+
+Daniel Fandrich (20 May 2009)
+- Added "non-existing host" test keywords to make it easy to skip those
+  tests on machines that have broken DNS configurations (such as
+  those configured to use OpenDNS).
+
+Daniel Stenberg (19 May 2009)
+- Kamil Dudka brought the patch from the Redhat bug entry
+  https://bugzilla.redhat.com/show_bug.cgi?id=427966 which was libcurl closing
+  a bad file descriptor when closing down the FTP data connection.  Caolan
+  McNamara seems to be the original author of it.

   Changelog for the c-ares project
 
+* November 2, 2009 (Yang Tse)
+- Renamed c-ares setup.h to ares_setup.h
+
+* October 31, 2009 (Yang Tse)
+- Symbol hiding configure options are named now --enable-symbol-hiding
+  and --disable-symbol-hiding in an attempt to make them less ambiguous.
+
+* October 30, 2009 (Yang Tse)
+- Many fixes for ares_parse_txt_reply()
+
+* October 29, 2009 (Daniel Stenberg)
+- Jakub Hrozek added ares_parse_txt_reply() for TXT parsing
+
+* October 29, 2009 (Yang Tse)
+- Updated MSVC 6.0 workspace and project files that allows building
+  dynamic and static c-ares libraries in debug and release flavours.
+  Additionally each of the three sample programs is built against
+  each of the four possible c-ares libraries, generating all this
+  a total number of 12 executables and 4 libraries.
+
+* October 28, 2009 (Yang Tse)
+- Initial step towards the ability to reduce c-ares exported symbols
+  when built as a shared library based on the 'visibility' attribute
+  for GNUC and Intel compilers and based on __global for Sun compilers,
+  taking also in account __declspec function decoration for Win32 and
+  Symbian DLL's.
+
+* October 27, 2009 (Yang Tse)
+- Fixed Pelles C Win32 target compilation issues.
+
+* October 23, 2009 (Yang Tse)
+- John Engelhart noticed an unreleased problem relative to a duplicate
+  ARES_ECANCELLED error code value and missing error code description.
+
+* October 7, 2009 (Yang Tse)
+- Overhauled ares__get_hostent() Fixing out of bounds memory overwrite
+  triggered with malformed /etc/hosts file. Improving parsing of /etc/hosts
+  file. Validating requested address family. Ensuring that failures always
+  return a NULL pointer. Adjusting header inclusions.
+
+* October 6, 2009 (Yang Tse)
+- Fix ssize_t redefinition errors on WIN64 reported by Alexey Simak.
+
+* September 29, 2009 (Yang Tse)
+- Make configure script also check if _REENTRANT definition is required to
+  make errno available as a preprocessor macro.
+
+* September 7, 2009 (Yang Tse)
+- Add T_SRV portability check to ares_parse_srv_reply.c
+
+* 4 Sep 2009 (Daniel Stenberg)
+- Jakub Hrozek added ares_parse_srv_reply() for SRV parsing
+
+* 3 Aug 2009 (Daniel Stenberg)
+- Joshua Kwan fixed the init routine to fill in the defaults for stuff that
+  fails to get inited by other means. This fixes a case of when the c-ares
+  init fails when internet access is fone.
+
+- Timo Teras changed the reason code used in the resolve callback done when
+  ares_cancel() is used, to be ARES_ECANCELLED instead of ARES_ETIMEOUT to
+  better allow the callback to know what's happening.
+
+* 14 Jul 2009 (Guenter Knauf)
+- renamed generated config.h to ares_config.h to avoid any future clashes
+  with config.h from other projects.
+
+* June 20 2009 (Yang Tse)
+- Refactor how libraries are checked for connect() function in configure
+  script and check for connect() as it is done for other functions.
+
+* June 19 2009 (Yang Tse)
+- Make sclose() function-like macro definition used to close a socket,
+  now solely based on HAVE_CLOSESOCKET and HAVE_CLOSESOCKET_CAMEL
+  config file preprocessor definitions
+
+* June 18 2009 (Yang Tse)
+- Add CloseSocket camel case function check for configure script.
+
+* June 17 2009 (Yang Tse)
+- Check for socket() and closesocket() as it is done for other functions
+  in configure script.
+
+* June 11 2009 (Yang Tse)
+- Modified buildconf so that when automake runs it copies missing files
+  instead of symlinking them.
+
+* June 8 2009 (Yang Tse)
+- Removed buildconf.bat from release and daily snapshot archives. This
+  file is only for CVS tree checkout builds.
+
+* May 26 2009 (Yang Tse)
+- Added --enable-curldebug configure option to enable and disable building
+  with the low-level curl debug memory tracking 'feature' to allow decoupled
+  setting from --enable-debug, allowing again to build c-ares independently
+  out of the CVS tree.
+
+  For the c-ares library option --enable-debug enables debug build features
+  which are _not_ related with memory tracking. For the c-ares library when
+  --enable-debug is given it does not enable the memory tracking feature. If
+  you wish to enable the curl debug memory tracking you must use configure
+  option --enable-curldebug explicitily to do so.
+
+  Internally, definition of preprocessor symbol DEBUGBUILD restricts code
+  which is only compiled for debug enabled builds. And symbol CURLDEBUG is
+  used to differentiate code which is _only_ used for memory tracking.
+
+  Make ares_init(), ares_dup() and ares_init_options() fail returning
+  ARES_ENOTINITIALIZED if library initialization has not been performed
+  calling ares_library_init().
+
+* May 20 2009 (Yang Tse)
+- Added ares_library_init() and ares_library_cleanup() man pages.
+
+* May 19 2009 (Yang Tse)
+- Introduced ares_library_init() and ares_library_cleanup() functions.
+
+  This is an API and ABI break for Win32/64 systems. Non-Win32/64 build targets
+  using c-ares 1.6.1 can still survive without calling these functions. Read all
+  the details on ares_library_init(3) and ares_library_cleanup(3) man pages that
+  are included.
+
+  curl/libcurl 7.19.5 is fully compatible with c-ares 1.6.1 on all systems.
+
+  In order to use c-ares 1.6.1 with curl/libcurl on Win32/64 systems it is
+  required that curl/libcurl is 7.19.5 or newer. In other words, it is not
+  possible on Win32/64 to use c-ares 1.6.1 with a curl/libcurl version less
+  than 7.19.5
+
 * May 11 2009 (Daniel Stenberg)
 - Gregor Jasny made c-ares link with libtool 's -export-symbols-regex option to
   only expose functions starting with ares_.
 
+* May 7 2009 (Yang Tse)
+- Fix an m4 overquoting triggering a spurious 'AS_TR_CPP' symbol definition
+  attempt in generated config.h
+
 * May 2 2009 (Yang Tse)
 - Use a build-time configured ares_socklen_t data type instead of socklen_t.

  o ares_gethostbyname() now supports 'AF_UNSPEC' as a family for resolving
    either AF_INET6 or AF_INET
  o a build-time configured ares_socklen_t is now used instead of socklen_t
+ o new ares_library_init() and ares_library_cleanup() functions
+ o new --enable-curldebug configure option
+ o ARES_ECANCELLED is now sent as reason for ares_cancel()
+ o added ares_parse_srv_reply()
+ o added ares_parse_txt_reply()
+ o new --enable-symbol-hiding configure option
 
 Fixed:
 
  o ares_parse_*_reply() functions now return ARES_EBADRESP instead of
    ARES_EBADNAME if the name in the response failed to decode
  o only expose/export symbols starting with 'ares_'
+ o fix \Device\TCP handle leaks triggered by buggy iphlpapi.dll
+ o init without internet gone no longer fails
+ o out of bounds memory overwrite triggered with malformed /etc/hosts file

-.SH DESCRIPTION
-The
-.B ares_getnameinfo
-function is defined for protocol-independent address translation. The function
-is a combination of \fIares_gethostbyaddr(3)\fP and \fIgetservbyport(3)\fP. The function will
-translate the address either by executing a host query on the name service channel
-identified by
-.IR channel 
-or it will attempt to resolve it locally if possible.
-The parameters
-.I sa
-and
-.I len
-give the address as a sockaddr structure, and
-.I flags
-gives the options that the function will use.  Valid flags are listed below:
-.TP 19
-.B ARES_NI_NOFQDN
-Only the nodename portion of the FQDN is returned for local hosts.
-.TP 19
-.B ARES_NI_NUMERICHOST
-The numeric form of the hostname is returned rather than the name.
-.TP 19
-.B ARES_NI_NAMEREQD
-An error is returned if the hostname cannot be found in the DNS.
-.TP 19
-.B ARES_NI_NUMERICSERV
-The numeric form of the service is returned rather than the name.
-.TP 19
-.B ARES_NI_TCP
-The service name is to be looked up for the TCP protocol.
-.TP 19
-.B ARES_NI_UDP
-The service name is to be looked up for the UDP protocol.
-.TP 19
-.B ARES_NI_SCTP
-The service name is to be looked up for the SCTP protocol.
-.TP 19
-.B ARES_NI_DCCP
-The service name is to be looked up for the DCCP protocol.
-.TP 19
-.B ARES_NI_NUMERICSCOPE
-The numeric form of the scope ID is returned rather than the name.
-.TP 19
-.B ARES_NI_LOOKUPHOST
-A hostname lookup is being requested.
-.TP 19
-.B ARES_NI_LOOKUPSERVICE
-A service name lookup is being requested.
-.PP
-When the query
-is complete or has 
-failed, the ares library will invoke \fIcallback\fP.  Completion or failure of 
-the query may happen immediately, or may happen during a later call to
-\fIares_process(3)\fP, \fIares_destroy(3)\fP or \fIares_cancel(3)\fP.
-.PP
-The callback argument
-.I arg
-is copied from the
-.B ares_getnameinfo
-argument
-.IR arg .
-The callback argument
-.I status
-indicates whether the query succeeded and, if not, how it failed.  It
-may have any of the following values:

-.B ARES_SUCCESS
-The host lookup completed successfully.
-.TP 19
-.B ARES_ENOTIMP
-The ares library does not know how to look up addresses of type

+.B #include <ares.h>
+.PP
+.B void ares_library_cleanup(void)
+.PP
+.B cc file.c -lcares
+.fi
+.SH DESCRIPTION
+.PP
+The
+.B ares_library_cleanup
+function uninitializes the c-ares library, freeing all resources
+previously aquired by \fIares_library_init(3)\fP when the library
+was initialized.
+.PP
+This function must be called when the program using c-ares will
+no longer need any c-ares function. Once the program has called
+\fIares_library_cleanup(3)\fP it shall not make any further call to any
+c-ares function.
+.PP
+This function does not cancel any pending c-ares lookups or requests
+previously done. Program  must use \fIares_cancel(3)\fP for this purpose.
+.PP
+.B This function is not thread safe.
+You have to call it once the program is about to terminate, but this call must
+be done once the program has terminated every single thread that it could have
+initiated. This is required to avoid potential race conditions in library
+deinitialization, and also due to the fact that \fIares_library_cleanup(3)\fP
+might call functions from other libraries that are thread unsafe, and could
+conflict with any other thread that is already using these other libraries.
+.PP
+Win32/64 application DLLs shall not call \fIares_library_cleanup(3)\fP from
+the DllMain function. Doing so will produce deadlocks and other problems.
+.SH AVAILABILITY
+This function was first introduced in c-ares version 1.6.1 along with the
+definition of preprocessor symbol \fICARES_HAVE_ARES_LIBRARY_CLEANUP\fP as an
+indication of the availability of this function.
+.PP
+Since the introduction of this function, it is absolutely mandatory to call it
+for any Win32/64 program using c-ares.
+.PP
+Non-Win32/64 systems can still use c-ares version 1.6.1 without calling
+\fIares_library_cleanup(3)\fP due to the fact that it is nearly a do-nothing
+function on non-Win32/64 platforms.

+.SH NAME
+ares_library_init \- c-ares library initialization
+.SH SYNOPSIS
+.nf
+.B #include <ares.h>
+.PP
+.B int ares_library_init(int \fIflags\fP)
+.PP
+.B cc file.c -lcares
+.fi
+.SH DESCRIPTION
+.PP
+The
+.B ares_library_init
+function performs initializations internally required by the c-ares
+library that must take place before any other function provided by
+c-ares can be used in a program.
+.PP
+This function must be called one time within the life of a program,
+before the program actually executes any other c-ares library function.
+Initializations done by this function remain effective until a
+call to \fIares_library_cleanup(3)\fP is performed.
+.PP
+Successive calls to this function do nothing, only the first call done
+when c-ares is in an uninitialized state is actually effective.
+.PP
+The
+.I flags
+parameter is a bit pattern that tells c-ares exactly which features
+should be initialized, as described below. Set the desired bits by
+ORing the values together. In normal operation you should specify
+\fIARES_LIB_INIT_ALL\fP. Don't use any other value unless you are
+familiar with it and trying to control some internal c-ares feature.
+.PP
+.B This function is not thread safe.
+You have to call it once the program has started, but this call must be done
+before the program starts any other thread. This is required to avoid
+potential race conditions in library initialization, and also due to the fact
+that \fIares_library_init(3)\fP might call functions from other libraries that
+are thread unsafe, and could conflict with any other thread that is already
+using these other libraries.
+.PP
+Win32/64 application DLLs shall not call \fIares_library_init(3)\fP from the
+DllMain function. Doing so will produce deadlocks and other problems.
+.SH FLAGS
+.TP 5
+.B ARES_LIB_INIT_ALL
+Initialize everything possible. This sets all known bits.
+.TP
+.B ARES_LIB_INIT_WIN32
+Initialize Win32/64 specific libraries.
+.TP
+.B ARES_LIB_INIT_NONE
+Initialize nothing extra. This sets no bit.
+.SH RETURN VALUE
+Upon successful completion, ares_library_init() will return 0.  Otherwise, a
+non-zero error number will be returned to indicate the error. Except for
+\fIares_strerror(3)\fP, you shall not call any other c-ares function upon
+\fIares_library_init(3)\fP failure.
+.SH AVAILABILITY
+This function was first introduced in c-ares version 1.6.1 along with the
+definition of preprocessor symbol \fICARES_HAVE_ARES_LIBRARY_INIT\fP as an
+indication of the availability of this function.
+.PP
+Since the introduction of this function it is absolutely mandatory to
+call it for any Win32/64 program using c-ares.
+.PP
+Non-Win32/64 systems can still use c-ares version 1.6.1 without calling
