+Version 7.16.0 (30 October 2006)
 
+Daniel (25 October 2006)
+- Fixed CURLOPT_FAILONERROR to return CURLE_HTTP_RETURNED_ERROR even for the
+  case when 401 or 407 are returned, *IF* no auth credentials have been given.
+  The CURLOPT_FAILONERROR option is not possible to make fool-proof for 401
+  and 407 cases when auth credentials is given, but we've now covered this
+  somewhat more.
+
+  You might get some amounts of headers transferred before this situation is
+  detected, like for when a "100-continue" is received as a response to a
+  POST/PUT and a 401 or 407 is received immediately afterwards.
+
+  Added test 281 to verify this change.
+
+Daniel (23 October 2006)
+- Ravi Pratap provided a major update with pipelining fixes. We also no longer
+  re-use connections (for pipelining) before the name resolving is done.
+
+Daniel (21 October 2006)
+- Nir Soffer made the tests/libtest/Makefile.am use a proper variable for all
+  the single test applications' link and dependences, so that you easier can
+  override those from the command line when using make.
+
+- Armel Asselin separated CA cert verification problems from problems with
+  reading the (local) CA cert file to let users easier pinpoint the actual
+  problem. CURLE_SSL_CACERT_BADFILE (77) is the new libcurl error code.
+
+Daniel (18 October 2006)
+- Removed the "protocol-guessing" for URLs with host names starting with FTPS
+  or TELNET since they are practically non-existant. This leaves us with only
+  three different prefixes that would assume the protocol is anything but
+  HTTP, and they are host names starting with "ftp.", "dict." or "ldap.".
+
+Daniel (17 October 2006)
+- Bug report #1579171 pointed out code flaws detected with "prefast", and they
+  were 1 - a too small memory clear with memset() in the threaded resolver and
+  2 - a range of potentially bad uses of the ctype family of is*() functions
+  such as isdigit(), isalnum(), isprint() and more. The latter made me switch
+  to using our own set of these functions/macros using uppercase letters, and
+  with some extra set of crazy typecasts to avoid mistakingly passing in
+  negative numbers to the underlying is*() functions.
+
+- With Jeff Pohlmeyer's help, I fixed the expire timer when using
+  curl_multi_socket() during name resolves with c-ares and the LOW_SPEED
+  options now work fine with curl_multi_socket() as well.
+
+Daniel (16 October 2006)
+- Added a check in configure that simply tries to run a program (not when
+  cross-compiling) in order to detect problems with run-time libraries that
+  otherwise would occur when the sizeof tests for curl_off_t would run and
+  thus be much more confusing to users. The check of course should run after
+  all lib-checks are done and before any other test is used that would run an
+  executable built for testing-purposes.
+
+Dan F (13 October 2006)
+- The tagging of application/x-www-form-urlencoded POST body data sent
+  to the CURLOPT_DEBUGFUNCTION callback has been fixed (it was erroneously
+  included as part of the header).  A message was also added to the
+  command line tool to show when data is being sent, enabled when
+  --verbose is used.
+
+Daniel (12 October 2006)
+- Starting now, adding an easy handle to a multi stack that was already added
+  to a multi stack will cause CURLM_BAD_EASY_HANDLE to get returned.
+
+- Jeff Pohlmeyer has been working with the hiperfifo.c example source code,
+  and while doing so it became apparent that the current timeout system for
+  the socket API really was a bit awkward since it become quite some work to
+  be sure we have the correct timeout set.
+
+  Jeff then provided the new CURLMOPT_TIMERFUNCTION that is yet another
+  callback the app can set to get to know when the general timeout time
+  changes and thus for an application like hiperfifo.c it makes everything a
+  lot easier and nicer. There's a CURLMOPT_TIMERDATA option too of course in
+  good old libcurl tradition.
+
+  Jeff has also updated the hiperfifo.c example code to use this news.
+
+Daniel (9 October 2006)
+- Bogdan Nicula's second test case (posted Sun, 08 Oct 2006) converted to test
+  case 535 and it now runs fine. Again a problem with the pipelining code not
+  taking all possible (error) conditions into account.
+
+Daniel (6 October 2006)
+- Bogdan Nicula's hanging test case (posted Wed, 04 Oct 2006) was converted to
+  test case 533 and the test now runs fine.
+
+Daniel (4 October 2006)
+- Dmitriy Sergeyev provided an example source code that crashed CVS libcurl
+  but that worked nicely in 7.15.5. I converted it into test case 532 and
+  fixed the problem.
+
+Daniel (29 September 2006)
+- Removed a few other no-longer present options from the header file.
+
+- Support for FTP third party transfers was removed. Here's why:
+
+  o The recent multi interface changes broke it and the design of the 3rd party
+    transfers made it very hard to fix the problems
+  o It was still blocking and thus nasty for the multi interface
+  o It was a lot of extra code for a very rarely used feature
+  o It didn't use the same code as for "plain" FTP transfers, so it didn't work
+    fine for IPv6 and it didn't properly re-use connections and more
+  o There's nobody around who's willing to work on and improve the existing
+    code
+
+  This does not mean that third party transfers are banned forever, only that
+  they need to be done better if they are to be re-added in the future.
+
+  The CURLOPT_SOURCE_* options are removed from the lib and so are the --3p*
+  options from the command line tool. For this reason, I also bumped the
+  version info for the lib.
+
+Daniel (28 September 2006)
+- Reported in #1561470 (http://curl.haxx.se/bug/view.cgi?id=1561470), libcurl
+  would crash if a bad function sequence was used when shutting down after
+  using the multi interface (i.e using easy_cleanup after multi_cleanup) so
+  precautions have been added to make sure it doesn't any more - test case 529
+  was added to verify.
+
+Daniel (27 September 2006)
+- The URL in the cookie jar file is now changed since it was giving a 404.
+  Reported by Timothy Stone. The new URL will take the visitor to a curl web
+  site mirror with the document.
+
+Daniel (24 September 2006)
+- Bernard Leak fixed configure --with-gssapi-libs.
+
+- Cory Nelson made libcurl use the WSAPoll() function if built for Windows
+  Vista (_WIN32_WINNT >= 0x0600)
+
+Daniel (23 September 2006)
+- Mike Protts added --ftp-ssl-control to make curl use FTP-SSL, but only
+  encrypt the control connection and use the data connection "plain".
+
+- Dmitriy Sergeyev provided a patch that made the SOCKS[45] code work better
+  as it now will read the full data sent from servers. The SOCKS-related code
+  was also moved to the new lib/socks.c source file.
+
+Daniel (21 September 2006)
+- Added test case 531 in an attempt to repeat bug report #1561470
+  (http://curl.haxx.se/bug/view.cgi?id=1561470) that is said to crash when an
+  FTP upload fails with the multi interface. It did not, but I made a failed
+  upload still assume the control connection to be fine.
+
+Daniel (20 September 2006)
+- Armel Asselin fixed problems when you gave a proxy URL with user name and
+  empty password or no password at all. Test case 278 and 279 were added to
+  verify.
+
+Daniel (12 September 2006)
+- Added docs/examples/10-at-a-time.c by Michael Wallner
+
+- Added docs/examples/hiperfifo.c by Jeff Pohlmeyer
+
+Daniel (11 September 2006)
+- Fixed my breakage from earlier today so that doing curl_easy_cleanup() on a
+  handle that is part of a multi handle first removes the handle from the
+  stack.
+
+- Added CURLOPT_SSL_SESSIONID_CACHE and --no-sessionid to disable SSL
+  session-ID re-use on demand since there obviously are broken servers out
+  there that misbehave with session-IDs used.
+
+- Jeff Pohlmeyer presented a *multi_socket()-using program that exposed a
+  problem with it (SIGSEGV-style). It clearly showed that the existing
+  socket-state and state-difference function wasn't good enough so I rewrote
+  it and could then re-run Jeff's program without any crash. The previous
+  version clearly could miss to tell the application when a handle changed
+  from using one socket to using another.
+
+  While I was at it (as I could use this as a means to track this problem
+  down), I've now added a 'magic' number to the easy handle struct that is
+  inited at curl_easy_init() time and cleared at curl_easy_cleanup() time that
+  we can use internally to detect that an easy handle seems to be fine, or at
+  least not closed or freed (freeing in debug builds fill the area with 0x13
+  bytes but in normal builds we can of course not assume any particular data
+  in the freed areas).
+
+Daniel (9 September 2006)
+- Michele Bini fixed how the hostname is put in NTLM packages. As servers
+  don't expect fully qualified names we need to cut them off at the first dot.
+
+- Peter Sylvester cleaned up and fixed the getsockname() uses in ftp.c. Some
+  of them can be completetly removed though...
+
+Daniel (6 September 2006)
+- Ravi Pratap and I have implemented HTTP Pipelining support. Enable it for a
+  multi handle using CURLMOPT_PIPELINING and all HTTP connections done on that
+  handle will be attempted to get pipelined instead of done in parallell as
+  they are performed otherwise.
+
+  As a side-effect from this work, connections are now shared between all easy
+  handles within a multi handle, so if you use N easy handles for transfers,
+  each of them can pick up and re-use a connection that was previously used by
+  any of the handles, be it the same or one of the others.
+
+  This separation of the tight relationship between connections and easy
+  handles is most noticable when you close easy handles that have been used in
+  a multi handle and check amount of used memory or watch the debug output, as
+  there are times when libcurl will keep the easy handle around for a while
+  longer to be able to close it properly. Like for sending QUIT to close down
+  an FTP connection.
+
+  This is a major change.
+  
 Daniel (4 September 2006)
 - Dmitry Rechkin (http://curl.haxx.se/bug/view.cgi?id=1551412) provided a
   patch that while not fixing things very nicely, it does make the SOCKS5

 .IP CURLMOPT_SOCKETFUNCTION
-Pass a pointer to a function matching the curl_socket_callback prototype. The
-\fIcurl_multi_socket(3)\fP functions inform the application about updates in
-the socket (file descriptor) status by doing none, one or multiple calls to
-the curl_socket_callback given in the \fBparam\fP argument. They update the

+with \fICURLMOPT_SOCKETDATA\fP.  See \fIcurl_multi_socket(3)\fP for more
+callback details.
 .IP CURLMOPT_SOCKETDATA
-Pass a pointer to whatever you want passed to the curl_socket_callback's forth
-argument, the userp pointer. This is not used by libcurl but only passed-thru
-as-is. Set the callback pointer with \fICURLMOPT_SOCKETFUNCTION\fP.

+forth argument, the userp pointer. This is not used by libcurl but only
+passed-thru as-is. Set the callback pointer with
+\fICURLMOPT_SOCKETFUNCTION\fP.
+.IP CURLMOPT_PIPELINING
+Pass a long set to 1 to enable or 0 to disable. Enabling pipelining on a multi
+handle will make it attempt to perform HTTP Pipelining as far as possible for
+transfers using this handle. This means that if you add a second request that
+can use an already existing connection, the second request will be \&"piped"
+on the same connection rather than being executed in parallell. (Added in
+7.16.0)
+.IP CURLMOPT_TIMERFUNCTION
+Pass a pointer to a function matching the \fBcurl_multi_timer_callback\fP
+prototype.  This function will then be called when the timeout value
+changes. The timeout value is at what latest time the application should call
+one of the \&"performing" functions of the multi interface
+(\fIcurl_multi_socket(3)\fP, \fIcurl_multi_socket_all(3)\fP and
+\fIcurl_multi_perform(3)\fP) - to allow libcurl to keep timeouts and retries
+etc to work. Libcurl attempts to limit calling this only when the fixed future
+timeout time actually change. See also \fICURLMOPT_TIMERDATA\fP. This callback
+can be used instead of, or in addition to, \fIcurl_multi_timeout(3)\fP. (Added

-  The 'shiper' tool is the test application I wrote that uses the new

-  select(), because I needed that during development (like until I had the
-  socket hash implemented etc) and because I haven't yet learned how to use
-  libevent or similar.
-
-  The hiper/shiper tools are very simple and initiates lots of connections and
-  have them running for the test period and then kills them all.
-
-  Since I wasn't done with the implementation until early January I haven't
-  had time to run very many measurements and checks, but I have done a few
-  runs with up to a few hundred connections (with a single active one). The
-  curl_multi_socket() invoke then takes 3-6 microseconds in average (using the
-  read-only-1-byte-at-a-time hack). If this number does increase a lot when we
-  add connections, it certainly matches my in my opinion very ambitious goal.

-
-  Some tests at 7000 and 9000 connections showed that the socket hash lookup
-  is somewhat of a bottle neck. Its current implementation may be a bit too
-  limiting. It simply has a fixed-size array, and on each entry in the array
-  it has a linked list with entries. So the hash only checks which list to
-  scan through. The code I had used so for used a list with merely 7 slots (as
-  that is what the DNS hash uses) but with 7000 connections that would make an
-  average of 1000 nodes in each list to run through. I upped that to 97 slots
-  (I believe a prime is suitable) and noticed a significant speed increase.  I
-  need to reconsider the hash implementation or use a rather large default
-  value like this. At 9000 connections I was still below 10us per call.

-  2 - More testing with actual URLs and complete from start to end transfers.

-Doing HTTP Pipelining with libcurl
-==================================
+HTTP Pipelining with libcurl
+============================
 
 Background
 
 Since pipelining implies that one or more requests are sent to a server before
-the previous response(s) have been received, it cannot be implemented easily
-into libcurl's easy interface due to its synchronous nature. We therefore only
-aim on adding it for multi interface use.
+the previous response(s) have been received, we only support it for multi
+interface use.
 
 Considerations
 
 When using the multi interface, you create one easy handle for each transfer.
 Bascially any number of handles can be created, added and used with the multi
 interface - simultaneously. It is an interface designed to allow many
-simultaneous transfers while still using a single thread.
-
-Pipelining however, will force us to allow apps to somehow "connect" two (or
-more) easy handles that are added to a multi handle. The first one sends a
-request and receives a response, just as normal, while the second (and
-subsequent) ones need to be attached to the first handle so that it can send
-its request on the same connection and then sit and wait until its response
-comes.
+simultaneous transfers while still using a single thread. Pipelining does not
+change any of these details.
 
 API
 
-We add a new option to curl_multi_setopt() called CURLMOPT_PIPELINING that
-enables "attempted pipelining" and then all easy handles used on that handle
-will attempt to use an existing pipeline.

   be considered for pipelining. Also, asking for explicit pipelining on handle
   X may be tricky when handle X get a closed connection.
 
-To Ponder About
-
 - We need options to control max pipeline length, and probably how to behave
   if we reach that limit. As was discussed on the list, it can probably be
   made very complicated, so perhaps we can think of a way to pass all
   variables involved to a callback and let the application decide how to act
   in specific situations. Either way, these fancy options are only interesting
   to work on when everything is working and we have working apps to test with.
-
-- Currently (before pipelining) we do not have any code or concept that lets
-  multiple handles share the same physical connection. We need to carefully
-  make sure that each easy handle knows exactly what they can do and when, on
-  the shared connection.
-
-- We need to keep a linked list of each handle that is part of a single pipe
-  so that if it breaks, we know which handles that need to resend their
-  requests. The pipe linked-lists could very well be "held" in the multi
-  handle struct so that they won't "belong" to a particular easy handle that
-  happens to be part of the pipeline during a certain period.
