7.19.1 coming up

problem with my CURLINFO_PRIMARY_IP fix from October 7th that caused a NULL
  pointer read. I also took the opportunity to clean up this logic (storing of
  the connection's IP address) somewhat as we had it stored in two different
  places and ways previously and they are now unified.

+- CURLINFO_FILETIME now works for file:// transfers as well

+- Bug #2218480 (http://curl.haxx.se/bug/view.cgi?id=2218480) pointed out a
+  problem with my CURLINFO_PRIMARY_IP fix from October 7th that caused a NULL
+  pointer read. I also took the opportunity to clean up this logic (storing of
+  the connection's IP address) somewhat as we had it stored in two different
+  places and ways previously and they are now unified.
+
+Yang Tse (3 Nov 2008)
+- Fix undersized IPv6 address internal buffer. IPv6 address strings longer
+  than 35 characters would be truncated.
+
+Daniel Stenberg (2 Nov 2008)
+- Daniel Johnson reported and fixed:
+
+  When c-ares isn't enabled, libcurl by default calls getaddrinfo with family
+  set to PF_UNSPEC which causes getaddrinfo to return all available addresses,
+  both IPv4 and IPv6. Libcurl then tries each one until it can connect. If the
+  net connection doesn't support IPv6, libcurl can still fall back to IPv4.
+
+  However, since c-ares doesn't support PF_UNSPEC, when it's used it defaults
+  to using family=PF_INET6 and therefore only returns IPv6 addresses when AAAA
+  records are available, even if IPv4 addresses are also available. The effect
+  is that since my ISP doesn't do IPv6, libcurl can't connect at all to a site
+  that has AAAA records. It will work if I explicitly use CURL_IPRESOLVE_V4 or
+  --ipv4 with the curl tool. I discovered this when curl would fail to connect
+  to seemingly random sites. It turns out they weren't random, they were sites
+  with AAAA records.
+
+  So now libcurl defaults to PF_INET... until c-ares has been tought to offer
+  both.
+
+Yang Tse (31 Oct 2008)
+- Tests 558 and 559 are stabilized. These two tests were initially introduced
+  to aid in the location of a seg-fault which was only triggered on non-debug
+  builds done with the icc 9.1 Intel compiler. Test 558 does not trigger the
+  problem, but test 559 does trigger it. As of today, it isn't yet absolutely
+  clear if it is a compiler optimizer issue or a memory corruption one.
+
+Yang Tse (30 Oct 2008)
+- Use our Curl_addrinfo structure definition to handle address info data even
+  when a system addrinfo struct is available. Provide and use a wrapper around
+  systems getaddrinfo function, Curl_getaddrinfo_ex which returns a pointer to
+  a list of dynamically allocated Curl_addrinfo structs.
+
+  Configure will check freeaddrinfo and getaddrinfo functions and define
+  preprocessor symbols HAVE_FREEADDRINFO and HAVE_GETADDRINFO when appropriate.
+
+Daniel Fandrich (29 Oct 2008)
+- Fixed a bug that caused a few bytes of garbage to be sent after a
+  curl_easy_pause() during a chunky upload. Reported by Steve Roskowski.
+
+Daniel Fandrich (28 Oct 2008)
+- Changed the "resolve" test precheck program to verify that an IPv6 socket
+  can be created before resolving the IPv6 name.  In the context of running
+  a test, it doesn't make sense to run an IPv6 test when a host is resolvable
+  but IPv6 isn't usable.  This should fix failures of test 1085 on hosts with
+  library and DNS support for IPv6 but where actual use of IPv6 has been
+  administratively disabled.
+
+Daniel Fandrich (24 Oct 2008)
+- Added experimental support for zlib and OpenSSL on Symbian OS.
+
+Daniel Fandrich (21 Oct 2008)
+- Fixed some problems with SFTP range support to fix test cases 634 through
+  637.
+
+Daniel Fandrich (17 Oct 2008)
+- Fixed a compile error reported by Albert Chin on AIX and IRIX when using
+  GTLS.
+
+Daniel Stenberg (16 Oct 2008)
+- Igor Novoseltsev added CURLOPT_PROXYUSER and CURLOPT_PROXYPASSWORD that then
+  make CURLOPT_PROXYUSERPWD sort of deprecated. The primary motive for adding
+  these new options is that they have no problems with the colon separator
+  that the CURLOPT_PROXYUSERPWD option does.
+
+Daniel Stenberg (15 Oct 2008)
+- Pascal Terjan filed bug #2154627
+  (http://curl.haxx.se/bug/view.cgi?id=2154627) which pointed out that libcurl
+  uses strcasecmp() in multiple places where it causes failures when the
+  Turkish locale is used. This is because 'i' and 'I' isn't the same letter so
+  strcasecmp() on those letters are different in Turkish than in English (or
+  just about all other languages). I thus introduced a totally new internal
+  function in libcurl (called Curl_raw_equal) for doing case insentive
+  comparisons for english-(ascii?) style strings that thus will make "file"
+  and "FILE" match even if the Turkish locale is selected.
+
+Daniel Fandrich (15 Oct 2008)
+- A <precheck> command is considered to have failed if it returns a non-zero
+  return code.  This way, if the precheck command can't be run at all for
+  whatever reason, it's treated as a precheck failure which causes the
+  test to be skipped.
+
+Daniel Stenberg (15 Oct 2008)
+- John Wilkinson filed bug #2155496
+  (http://curl.haxx.se/bug/view.cgi?id=2155496) pointing out an error case
+  without a proper human-readable error message. When a read callback returns
+  a too large value (like when trying to return a negative number) it would
+  trigger and the generic error message then makes the proplem slightly
+  different to track down. I've added an error message for this now.
+
+Daniel Fandrich (9 Oct 2008)
+- Fixed the --interface option to work with IPv6 connections on glibc
+  systems supporting getifaddrs(). Also fixed a problem where an IPv6
+  address could be chosen instead of an IPv4 one for --interface when it
+  involved a name lookup.
+
+Daniel Fandrich (8 Oct 2008)
+- Added tests 1082 through 1085 to test symbolic --interface parameters
+
+- Added tests 633 through 637 to test the new file range support for SFTP.
+  All but the first test cause an infinite loop or other failure and so
+  are added to DISABLED.
+
+Daniel Stenberg (8 Oct 2008)
+- John Wilkinson filed bug #2152270
+  (http://curl.haxx.se/bug/view.cgi?id=2152270) which identified and fixed a
+  CURLINFO_REDIRECT_URL memory leak and an additional wrong-doing:
+
+  Any subsequent transfer with a redirect leaks memory, eventually crashing
+  the process potentially.
+
+  Any subsequent transfer WITHOUT a redirect causes the most recent redirect
+  that DID occur on some previous transfer to still be reported.
+
+- Igor Novoseltsev filed bug #2111613
+  (http://curl.haxx.se/bug/view.cgi?id=2111613) that eventually identified a
+  flaw in how the multi_socket interface in some cases missed to call the
+  timeout callback when easy interfaces are removed and added within the same
+  millisecond.
+
+- Igor Novoseltsev brought a patch that introduced two new options to
+  curl_easy_setopt: CURLOPT_USERNAME and CURLOPT_PASSWORD that sort of
+  deprecates the good old CURLOPT_USERPWD since they allow applications to set
+  the user name and password independently and perhaps more importantly allow
+  both to contain colon(s) which CURLOPT_USERPWD doesn't fully support.
+
+Daniel Fandrich (7 Oct 2008)
+- Changed the handling of read/write errors in Curl_perform() to allow a
+  a fresh connection to be made in such cases and the request retransmitted.
+  This should fix test case 160.  Added test case 1079 in an attempt to
+  test a similar connection dropping scenario, but as a race condition, it's
+  hard to test reliably.
+
+- Created test cases 1080 and 1081 to reproduce a problem of
+  CURLINFO_REDIRECT_URL leaking memory and returning incorrect results when
+  two URLs are requested. Reported by vmpdemo in bug #2152270
+
+Daniel Stenberg (7 Oct 2008)
+- Fixed CURLINFO_PRIMARY_IP: When libcurl created a connection to host A then
+  the app re-used the handle to do a connection to host B and then again
+  re-used the handle to host A, it would not update the info with host A's IP
+  address (due to the connection being re-used) but it would instead report
+  the info from host B.
+
+Yang Tse (7 Oct 2008)
+- Added --enable-optimize configure option to enable and disable compiler
+  optimizations to allow decoupled setting from --enable-debug.
+
+Yang Tse (2 Oct 2008)
+- Added --enable-warnings configure option to enable and disable strict
+  compiler warnings to allow decoupled setting from --enable-debug.
+
+  runtests.pl will now run with picky compiler warnings enabled unless
+  explicitly disabled.
+  
+Daniel Fandrich (1 Oct 2008)
+- "make clean" now cleans out the docs and tests directories, too.
+
+Daniel Stenberg (30 Sep 2008)
+- The libcurl FTP code now returns CURLE_REMOTE_FILE_NOT_FOUND error when SIZE
+  gets a 550 response back for the cases where a download (or NOBODY) is
+  wanted. It still allows a 550 as response if the SIZE is used as part of an
+  upload process (like if resuming an upload is requested and the file isn't
+  there before the upload). I also modified the FTP test server and a few test
+  cases accordingly to match this modified behavior.
+
+Daniel Stenberg (29 Sep 2008)
+- Daniel Egger provided a patch that allows you to disable proxy support in
+  libcurl to somewhat reduce the size of the binary. Run configure
+  --disable-proxy.
+  
+Daniel Fandrich (29 Sep 2008)
+- Moved all signal-based name resolution timeout handling into a single new
+  Curl_resolv_timeout function to reduce coupling.
+
+Daniel Stenberg (29 Sep 2008)
+- Ian Lynagh provided a patch that now makes CURLOPT_RANGE work fine for SFTP
+  downloads!
+
+- Maxim Ivanov filed bug report #2107803
+  (http://curl.haxx.se/bug/view.cgi?id=2107803) "no CURLINFO_REDIRECT_URL in
+  multi mode" together with a patch that fixed the problem.
+  
+Daniel Stenberg (25 Sep 2008)
+- Emanuele Bovisio submitted bug report #2126435. We fixed the HTTP Digest
+  auth code to not behave badly when getting a blank realm with
+  realm="". http://curl.haxx.se/bug/view.cgi?id=2126435
+
+Daniel Fandrich (23 Sep 2008)
+- Make sure not to dereference the wrong UrlState proto union member when
+  switching from one protocol to another in a single request (e.g.
+  redirecting from HTTP to FTP as in test 1055) by resetting
+  state.expect100header before every request.
+
+Daniel Stenberg (23 Sep 2008)
+- Introducing Jamie Lokier's function for date to epoch conversion used in the
+  date parser function. This makes our function less dependent on system-
+  provided functions and instead we do all the magic ourselves. We also no
+  longer depend on the TZ environment variable. Switching to our own converter
+  has some side-effect and they are noted here for future reference (taken
+  from a mail by mr Lokier):
+
+  time_t is not measured in seconds in the ANSI C standard - or even counted
+  uniformly - weird platforms can use other numeric representations of dates
+  in time_t - hence the difftime() function.
+
+  On POSIX time_t is measured in UTC seconds, which means not including leap
+  seconds.  But it's mentioned in a few places that some old POSIX-ish
+  environments include leap seconds in their time_t counts...
+
+  I'm pretty sure [the new implementation is] correct on anything truly POSIX.
+  And it's obviously a lot less dependent on platform quirks and corner cases
+  in many ways than the mktime() version.
+
+- Rob Crittenden brought a patch to "add some locking for thread-safety to NSS
+  implementation".
+
+Daniel Stenberg (22 Sep 2008)
+- Made the SOCKS code use the new Curl_read_plain() function to fix the bug
+  Markus Moeller reported: http://curl.haxx.se/mail/archive-2008-09/0016.html
+
+- recv() errors other than those equal to EAGAIN now cause proper
+  CURLE_RECV_ERROR to get returned. This made test case 160 fail so I've now
+  disabled it until we can figure out another way to exercise that logic.
+
+- Michael Goffioul filed bug report #2107377 "Problem with multi + GnuTLS +
+  proxy" (http://curl.haxx.se/bug/view.cgi?id=2107377) that showed how a multi
+  interface using program didn't work when built with GnuTLS and a CONNECT
+  request was done over a proxy (basically test 502 over a proxy to a HTTPS
+  site). It turned out the ssl connect function would get called twice which
+  caused the second call to fail.
+
+Daniel Fandrich (22 Sep 2008)
+- Fixed test 539 to handle an out of memory condition that shows up now
+  that memdebug.h is included in the test programs.
+
+Yang Tse (20 Sep 2008)
+- Fix regression in configure script which affected OpenSSL builds on MSYS.
+
+Yang Tse (19 Sep 2008)
+- configure script now checks availability of the alarm() function.
+
+Daniel Fandrich (18 Sep 2008)
+- Don't bother to install a SIGALRM handler unless alarm() is available.
+  Also, leave the existing SIGALRM handler alone if the timeout is too small
+  to handle.
+
+Daniel Fandrich (17 Sep 2008)
+- Removed reference to curl-ca-bundle.crt in the host verification failure
+  error message.
+
+Yang Tse (17 Sep 2008)
+- Improve configure detection of gethostname(), localtime_r(), strstr(),
+  getservbyport_r(), gethostbyaddr_r() and gethostbyname_r().
+
+Yang Tse (14 Sep 2008)
+- Improve configure detection of strcasecmp(), strcasestr(), strcmpi(),
+  stricmp(), strlcat(), strncasecmp(), strncmpi() and strnicmp().
+
+Yang Tse (13 Sep 2008)
+- Disable tracking of fdopen() calls in the low-level memory leak tracking
+  code when fdopen() is not available, to avoid compiler error.
+
+Yang Tse (12 Sep 2008)
+- Further adjust detection of strerror_r() in the configure process, and
+  ensure that errno is not modified inside Curl_strerror().
+
+Yang Tse (10 Sep 2008)
+- Improve detection of gmtime_r(), strtoll(), sigaction(), strtok_r(),
+  strdup() and ftruncate() in the configure process.
+
+Daniel Fandrich (9 Sep 2008)
+- Mike Revi discovered some swapped speed switches documented in the curl man
+  page.
+
+- Checked in some documentation and code improvements and fixes that I
+  discovered in the FreeBSD ports system.
+
+Daniel Stenberg (8 Sep 2008)
+- Dmitry Kurochkin patched a problem: I have found bug in pipelining through
+  proxy. I have a transparent proxy. When running with http_proxy environment
+  variable not set my test completes fine (it goes through transparent
+  proxy). When I set http_proxy variable my test hangs after the first
+  downloaded is complete. Looks like the second handle never gets out from
+  WAITDO state.
+
+  The fix: It makes checkPendPipeline move 1 handler from pend pipe to send
+  pipe if pipelining is not supported by server but there are no handles in
+  send and recv pipes.
+
+- Stefan Krause pointed out that libcurl would wrongly send away cookies to
+  sites in cases where the cookie clearly has a very old expiry date. The
+  condition was simply that libcurl's date parser would fail to convert the
+  date and it would then count as a (timed-based) match. Starting now, a
+  missed date due to an unsupported date format or date range will now cause
+  the cookie to not match.
+
+Daniel Fandrich (5 Sep 2008)
+- Improved the logic that decides whether to use HTTP 1.1 features or not in a
+  request.  Setting a specific version with CURLOPT_HTTP_VERSION overrides
+  all other checks, but otherwise, a 1.0 request will be made if the server
+  is known to support only 1.0 because it previously responded so and the
+  connection was kept alive, or a response to a previous request on this handle
+  came back as 1.0. The latter could take place in cases like redirection or
+  authentication where several requests have to be made before the operation
+  is complete.  If any one of the servers in a redirection chain supports only
+  1.0, then remaining requests will be sent in 1.0 mode.
+
+- Detect cases where an upload must be sent chunked and the server supports
+  only HTTP 1.0 and return CURLE_UPLOAD_FAILED.
+
+Daniel Stenberg (5 Sep 2008)
+- Martin Drasar provided the CURLOPT_POSTREDIR patch. It renames
+  CURLOPT_POST301 (but adds a define for backwards compatibility for you who
+  don't define CURL_NO_OLDIES). This option allows you to now also change the
+  libcurl behavior for a HTTP response 302 after a POST to not use GET in the
+  subsequent request (when CURLOPT_FOLLOWLOCATION is enabled). I edited the
+  patch somewhat before commit. The curl tool got a matching --post302
+  option. Test case 1076 was added to verify this.
+
+- Introducing CURLOPT_CERTINFO and the corresponding CURLINFO_CERTINFO. By
+  enabling this feature with CURLOPT_CERTINFO for a request using SSL (HTTPS
+  or FTPS), libcurl will gather lots of server certificate info and that info
+  can then get extracted by a client after the request has completed with
+  curl_easy_getinfo()'s CURLINFO_CERTINFO option. Linus Nielsen Feltzing
+  helped me test and smoothen out this feature.
+
+  Unfortunately, this feature currently only works with libcurl built to use
+  OpenSSL.
+
+  This feature was sponsored by networking4all.com - thanks!
+
+- Dmitriy Sergeyev pointed out that curl_easy_pause() didn't unpause properly
+  during certain conditions. I also changed this code to use realloc() based
+  on Daniel Fandrich's suggestion.
+
+Guenter Knauf (4 Sep 2008)
+- MingW32 non-configure builds are now largefile feature enabled by default.
+  NetWare LIBC builds are also now largefile feature enabled by default.
+
+Yang Tse (4 Sep 2008)
+- Several fixes related with print formatting string directives.
+
+Daniel Fandrich (3 Sep 2008)
+- Search for the FreeBSD CA cert file /usr/local/share/certs/ca-root.crt
+
+Daniel Fandrich (2 Sep 2008)
+- Fixed an out of memory problem that caused torture test failures in tests
+  706 and 707.
+
+Daniel Stenberg (2 Sep 2008)
+- Keith Mok added supported_protocols and supported_features to the pkg-config
+  file for libcurl, and while doing that fix he unified with curl-config.in
+  how the supported protocols and features are extracted and used, so both those
+  tools should now always be synced.

   Changelog for the c-ares project
 
+* Nov 1 2008 (Daniel Stenberg)
+- Carlo Contavalli added support for the glibc "rotate" option, as documented
+  in man resolv.conf: 
+
+  causes round robin selection of nameservers from among those listed.  This
+  has the effect of spreading the query load among all listed servers, rather
+  than having all clients try the first listed server first every time.
+
+  You can enable it with ARES_OPT_ROTATE
+
+* Oct 21 2008 (Yang Tse)
+  Charles Hardin added handling of EINPROGRESS for UDP connects.
+
+* Oct 18 2008 (Daniel Stenberg)
+  Charles Hardin made adig support a regular numerical dotted IP address for the
+  -s option as well.
+
+* Oct 7 2008 (Yang Tse)
+- Added --enable-optimize configure option to enable and disable compiler
+  optimizations to allow decoupled setting from --enable-debug.
+
+* Oct 2 2008 (Yang Tse)
+- Added --enable-warnings configure option to enable and disable strict
+  compiler warnings to allow decoupled setting from --enable-debug.
+
+* Sep 17 2008 (Yang Tse)
+- Code reorganization to allow internal/private use of "nameser.h" to any
+  system that lacks arpa/nameser.h or arpa/nameser_compat.h header files.
+
+* Sep 16 2008 (Yang Tse)
+- Code reorganization to allow internal/private use of ares_writev to any
+  system that lacks the writev function.
+
+* Sep 15 2008 (Yang Tse)
+- Code reorganization to allow internal/private use of ares_strcasecmp to any
+  system that lacks the strcasecmp function.
+
+- Improve configure detection of some string functions.
+
+* Sep 11 2008 (Yang Tse)
+- Code reorganization to allow internal/private use of ares_strdup to any
+  system that lacks the strdup function.

   mandated by RFC4217. This kind of connection then of course uses the
   standard FTP port 21 by default.
 
+  4.16 My HTTP POST or PUT requests are slow!
+
+  libcurl makes all POST and PUT requests (except for POST requests with a
+  very tiny request body) use the "Expect: 100-continue" header. This header
+  allows the server to deny the operation early so that libcurl can bail out
+  already before having to send any data. This is useful in authentication
+  cases and others.
+
+  However, many servers don't implement the Expect: stuff properly and if the
+  server doesn't respond (positively) within 1 second libcurl will continue
+  and send off the data anyway.
+
+  You can disable libcurl's use of the Expect: header the same way you disable
+  any header, using -H / CURLOPT_HTTPHEADER, or by forcing it to use HTTP 1.0.

+
+  libcurl is a C library, it doesn't know anything about C++ member functions.
+
+  You can overcome this "limitation" with a relative ease using a static
