- Proper handling of STARTTLS on SMTP, taking CURLUSESSL_TRY into account.
- SMTP falls back to RFC821 HELO when EHLO fails (and SSL is not required).
- Use of true local host name (i.e.: via gethostname()) when available, as
  default argument to SMTP HELO/EHLO.
- Test case 804 for HELO fallback.

- Fixed the SMTP compliance by making sure RCPT TO addresses are specified
  properly in angle brackets. Recipients provided with CURLOPT_MAIL_RCPT now
  get angle bracket wrapping automatically by libcurl unless the recipient
  starts with an angle bracket as then the app is assumed to deal with that
  properly on its own.

- I made the SMTP code expect a 250 response back from the server after the
  full DATA has been sent, and I modified the test SMTP server to also send
  that response. As usual, the DONE operation that is made after a completed
  transfer is still not doable in a non-blocking way so this waiting for 250
  is unfortunately made blockingly.

- When downloading compressed content over HTTP and the app asked libcurl to
  automatically uncompress it with the CURLOPT_ENCODING option, libcurl could
  wrongly provide the callback with more data than the maximum documented
  amount. An application could thus get tricked into badness if the maximum
  limit was trusted to be enforced by libcurl itself (as it is documented).

Daniel Stenberg (1 Feb 2010)
- Using the multi_socket API, it turns out at times it seemed to "forget"
  connections (which caused a hang). It turned out to be an existing (7.19.7)
  bug in libcurl (that's been around for a long time) and it happened like

  The app calls curl_multi_add_handle() to add a new easy handle, libcurl will
  then set it to timeout in 1 millisecond so libcurl will tell the app about

  The app's timeout fires off that there's a timeout, the app calls libcurl as
  we so often document it:

  do {
   res = curl_multi_socket_action(... TIMEOUT ...);
  } while(CURLM_CALL_MULTI_PERFORM == res);

  And this is the problem number one:

  When curl_multi_socket_action() is called with no specific handle, but only
  a timeout-action, it will *only* perform actions within libcurl that are
  marked to run at this time. In this case, the request would go from INIT to
  CONNECT and return CURLM_CALL_MULTI_PERFORM. When the app then calls libcurl
  again, there's no timer set for this handle so it remains in the CONNECT
  state. The CONNECT state is a transitional state in libcurl so it reports no
  sockets there, and thus libcurl never tells the app anything more about that
  easy handle/connection.

  libcurl _does_ set a 1ms timeout for the handle at the end of
  multi_runsingle() if it returns CURLM_CALL_MULTI_PERFORM, but since the loop
  is instant the new job is not ready to run at that point (and there's no
  code that makes libcurl call the app to update the timout for this new
  timeout). It will simply rely on that some other timeout will trigger later
  on or that something else will update the timeout callback. This makes the
  bug fairly hard to repeat.

  The fix made to adress this issue:

  We introduce a loop in lib/multi.c around all calls to multi_runsingle() and
  simply check for CURLM_CALL_MULTI_PERFORM internally. This has the added
  benefit that this goes in line with my long-term wishes to get rid of the
  CURLM_CALL_MULTI_PERFORM all together from the public API.

  The downside of this fix, is that the counter we return in 'running_handles'
  in several of our public functions then gets a slightly new and possibly
  confusing behavior during times:

  If an app adds a handle that fails to connect (very quickly) it may just
  as well never appear as a 'running_handle' with this fix. Previously it
  would first bump the counter only to get it decreased again at next call.
  Even I have used that change in handle counter to signal "end of a
  transfer". The only *good* way to find the end of a individual transfer
  is calling curl_multi_info_read() to see if it returns one.

  Of course, if the app previously did the looping before it checked the
  counter, it really shouldn't be any new effect.

- Constantine Sapuntzakis' and Joshua Kwan's work done in the last four months
  relative to the asynchronous DNS lookups, along with with some integration
  adjustments I have done are finally committed to CVS.

  Currently these enhancements will benefit builds done using c-ares on any
  platform as well as Windows builds using the default threaded resolver.

  This release does not make generally available POSIX threaded DNS lookups
  yet. There is no configure option to enable this feature yet. It is possible
  to experimantally try this feature running configure with compiler flags that
  make simultaneous definition of preprocessor symbols USE_THREADS_POSIX and
  HAVE_PTHREAD_H, as well as whatever reentrancy compiler flags and linker ones
  are required to link and properly use pthread_* functions on each platform.

- As was pointed out on the http-state mailing list, the order of cookies in a
  HTTP Cookie: header _needs_ to be sorted on the path length in the cases
  where two cookies using the same name are set more than once using
  (overlapping) paths. Realizing this, identically named cookies must be
  sorted correctly. But detecting only identically named cookies and take care
  of them individually is harder than just to blindly and unconditionally sort
  all cookies based on their path lengths. All major browsers also already do
  this, so this makes our behavior one step closer to them in the cookie area.

  Test case 8 was the only one that broke due to this change and I updated it

- Suppressed side effect of OpenSSL configure checks, which prevented NSS from

- The tests/ script now checks to see if the test case that runs is

  included in release archives and forgetting to add files there is a common
  mistake. This is an attempt to make it harder to forget.

- Johan van Selst found and fixed a OpenSSL session ref count leak:

  ossl_connect_step3() increments an SSL session handle reference counter on
  each call. When sessions are re-used this reference counter may be
  incremented many times, but it will be decremented only once when done (by
  Curl_ossl_session_free()); and the internal OpenSSL data will not be freed
  if this reference count remains positive. When a session is re-used the
  reference counter should be corrected by explicitly calling
  SSL_SESSION_free() after each consecutive SSL_get1_session() to avoid
  introducing a memory leak.

- Ingmar Runge enhanced libcurl's FTP engine to support the PRET command. This
  command is a special "hack" used by the drftpd server, but even though it is
  a custom extension I've deemed it fine to add to libcurl since this server
  seems to survive and people keep using it and want libcurl to support
  it. The new libcurl option is named CURLOPT_FTP_USE_PRET, and it is also
  usable from the curl tool with --ftp-pret. Using this option on a server
  that doesn't support this command will make libcurl fail.

  I added test cases 1107 and 1108 to verify the functionality.

  The PRET command is documented at

- Follow-up fix for the proxy fix I did for Jon Nelson's bug. It turned out I
  was a bit too quick and broke test case 1101 with that change. The order of
  some of the setups is sensitive. I now changed it slightly again to make
  sure we do them in this order:

  1 - parse URL and figure out what protocol is used in the URL
  2 - prepend protocol:// to URL if missing
  3 - parse name+password off URL, which needs to know what protocol is used
      (since only some allows for name+password in the URL)
  4 - figure out if a proxy should be used set by an option
  5 - if no proxy option, check proxy environment variables
  6 - run the protocol-specific setup function, which needs to have the proxy
      already set

Daniel Stenberg (15 Dec 2009)
- Jon Nelson found a regression that turned out to be a flaw in how libcurl
  detects and uses proxies based on the environment variables. If the proxy
  was given as an explicit option it worked, but due to the setup order
  mistake proxies would not be used fine for a few protocols when picked up
  from '[protocol]_proxy'. Obviously this broke after 7.19.4. I now also added
  test case 1106 that verifies this functionality.

- Siegfried Gyuricsko found out that the curl manual said --retry would retry
  on FTP errors in the transient 5xx range. Transient FTP errors are in the
  4xx range. The code itself only tried on 5xx errors that occured _at login_.
  Now the retry code retries on all FTP transfer failures that ended with a
  4xx response.

Daniel Stenberg (1 Dec 2009)
- If the Expect: 100-continue header has been set by the application through

  least) doesn't handle this properly. Martin Storsjo provided the fix!

  curl to believe things were fine.

  wrong percentage for small files, most notable for <1000 bytes and could
  easily end up showing more than 100% at the end. It also didn't show any

  less than 100 bytes.

- 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.

  the libssh2 configure check was changed to use pkg-config since the
  --static flag would add the dependencies automatically.

  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.

  setup the LIBS/LDFLAGS/CFLAGS etc properly. The previous last resort would

- 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).

- I introduced configure script option --enable-curldebug which now allows
  the decoupled enabling or disabling of the curl debug memory tracking

  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.

  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
  ( and helped us verify the fix.

- Pramod Sharma reported and tracked down a bug when doing FTP over a HTTP
  proxy. libcurl would then wrongly close the connection after each
  request. In his case it had the weird side-effect that it killed NTLM auth
  for the proxy causing an inifinite loop!

  I added test case 1098 to verify this fix. The test case does however not
  properly verify that the transfers are done persistently - as I couldn't
  think of a clever way to achieve it right now - but you need to read the
  stderr output after a test run to see that it truly did the right thing.

- bug report #2727981 ( by Martin
  Storsjö pointed out how setting CURLOPT_NOBODY to 0 could be downright
  confusing as it set the method to either GET or HEAD. The example he showed
  looked like:

   curl_easy_setopt(curl, CURLOPT_PUT, 1);
   curl_easy_setopt(curl, CURLOPT_NOBODY, 0);

  The new way doesn't alter the method until the request is about to start. If
  CURLOPT_NOBODY is then 1 the HTTP request will be HEAD. If CURLOPT_NOBODY is
  0 and the request happens to have been set to HEAD, it will then instead be
  set to GET. I believe this will be less surprising to users, and hopefully
  not hit any existing users badly.

  having run the configure script with _FILE_OFFSET_BITS different than
  64 and using the ILP32 data model.

  curl_easy_duphandle did not necessarily duplicate the CURLOPT_COOKIEFILE
  option. It only enabled the cookie engine in the destination handle if
  data->cookies is not NULL (where data is the source handle). In case of a
  newly initialized handle which just had the cookie support enabled by a
  curl_easy_setopt(handle, CURL_COOKIEFILE, "")-call, handle->cookies was
  still NULL because the setopt-call only appends the value to
  data->change.cookielist, hence duplicating this handle would not have the
  cookie engine switched on.

  We also concluded that the slist-functionality would be suitable for being
  put in its own module rather than simply hanging out in lib/sendf.c so I
  created lib/slist.[ch] for them.

- David Kierznowski notified us about a security flaw
  ( also known as CVE-2009-0037) in
  which previous libcurl versions (by design) can be tricked to access an
  arbitrary local/different file instead of a remote one when
  CURLOPT_FOLLOWLOCATION is enabled. This flaw is now fixed in this release
  together this the addition of two new setopt options for controlling this
  new behavior:

  o CURLOPT_REDIR_PROTOCOLS controls what protocols libcurl is allowed to
  follow to when CURLOPT_FOLLOWLOCATION is enabled. By default, this option
  excludes the FILE and SCP protocols and thus you nee to explicitly allow
  them in your app if you really want that behavior.

  o CURLOPT_PROTOCOLS controls what protocol(s) libcurl is allowed to fetch
  using the primary URL option. This is useful if you want to allow a user or
  other outsiders control what URL to pass to libcurl and yet not allow all
  protocols libcurl may have been built to support.

- I renamed everything in the windows builds files that used the name 'curllib'
  to the proper 'libcurl' as clearly this caused confusion.

- Linus Nielsen Feltzing reported and helped me repeat and fix a problem with
  FTP with the multi interface: when a transfer fails, like when aborted by a
  write callback, the control connection was wrongly closed and thus not
  re-used properly.

  This change is also an attempt to cleanup the code somewhat in this area, as
  now the FTP code attempts to keep (better) track on pending responses
  necessary to get read in ftp_done().

  libcurl did a superfluous 1000ms wait when doing SFTP downloads!

  We read data with libssh2 while doing the "DO" operation for SFTP and then
  when we were about to start getting data for the actual file part, the
  "TRANSFER" part, we waited for socket action (in 1000ms) before doing a
  libssh2-read. But in this case libssh2 had already read and buffered the
  data so we ended up always just waiting 1000ms before we get working on the

- FTP downloads (i.e.: RETR) ending with code 550 now return error

- Kamil Dudka made NSS-powered builds compile and run again!

- A second follow-up change by Andre Guibert de Bruet to fix a related memory
  leak like that fixed on the 14th. When zlib returns failure, we need to
  cleanup properly before returning error.

- CURLOPT_FTP_CREATE_MISSING_DIRS can now be set to 2 in addition to 1 for
  plain FTP connections, and it will then allow MKD to fail once and retry the
  CWD afterwards. This is especially useful if you're doing many simultanoes
  connections against the same server and they all have this option enabled,
  as then CWD may first fail but then another connection does MKD before this
  connection and thus MKD fails but trying CWD works! The numbers can
  (should?) now be set with the convenience enums now called

  Tests has proven that if you're making an application that uploads a set of
  files to an ftp server, you will get a noticable gain in speed if you're
  using multiple connections and this option will be then be very useful.

- Andre Guibert de Bruet found and fixed a memory leak in the content encoding
  code, which could happen on libz errors.

- Added support for Digest and NTLM authentication using GnuTLS.

Daniel Stenberg (11 Feb 2009)
- CURLINFO_CONDITION_UNMET was added to allow an application to get to know if
  the condition in the previous request was unmet. This is typically a time
  condition set with CURLOPT_TIMECONDITION and was previously not possible to
  reliably figure out. From bug report #2565128
  ( filed by Jocelyn Jaubert.

- Don't add the standard /usr/lib or /usr/include paths to LDFLAGS and CPPFLAGS
  (respectively) when --with-ssl=/usr is used (patch based on FreeBSD).

1479 1480 1481 1482
- Added an explicit buffer limit check in msdosify() (patch based on FreeBSD).
  This couldn't ever overflow in curl, but might if the code were used
  elsewhere or under different conditions.

1483 1484 1485 1486 1487
Daniel Stenberg (3 Feb 2009)
- Hidemoto Nakada provided a small fix that makes it possible to get the
  CURLINFO_CONTENT_LENGTH_DOWNLOAD size from file:// "transfers" with
  CURLOPT_NOBODY set true.

- Patrick Scott found a rather large memory leak when using the multi
  interface and setting CURLMOPT_MAXCONNECTS to something less than the number
  of handles you add to the multi handle. All the connections that didn't fit
  in the cache would not be properly disconnected nor freed!

1494 1495 1496 1497 1498 1499 1500 1501 1502
- Craig A West brought us: libcurl now defaults to do CONNECT with HTTP
  version 1.1 instead of 1.0 like before. This change also introduces the new
  proxy type for libcurl called 'CURLPROXY_HTTP_1_0' that then allows apps to
  switch (back) to CONNECT 1.0 requests. The curl tool also got a --proxy1.0
  option that works exactly like --proxy but sets CURLPROXY_HTTP_1_0.

  I updated all test cases cases that use CONNECT and I tried to do some using
  --proxy1.0 and some updated to do CONNECT 1.1 to get both versions run.

- When building with c-ares 1.6.1 (not yet released) or later and IPv6 support
  enabled, we can now take advantage of its brand new AF_UNSPEC support in
  ares_gethostbyname(). This makes test case 241 finally run fine for me with
1507 1508 1509
  this setup since it now parses the "::1 ip6-localhost" line fine in my
  /etc/hosts file!

- Scott Cantor filed bug report #2550061
  ( mentioning that I failed to
  properly make sure that the VC9 makefiles got included in the latest
  release. I've now fixed the release script and verified it so next release
  will hopefully include them properly!

Yang Tse (29 Jan 2009)
- Introduced curl_sspi.c and curl_sspi.h for the implementation of functions
  Curl_sspi_global_init() and Curl_sspi_global_cleanup() which previously were
  named Curl_ntlm_global_init() and Curl_ntlm_global_cleanup() in http_ntlm.c
  Also adjusted socks_sspi.c to remove the link-time dependency on the Windows
  SSPI library using it now in the same way as it was done in http_ntlm.c.

Daniel Stenberg (28 Jan 2009)
- Markus Moeller introduced two new options to libcurl:
  to do GSS-style authentication with SOCKS5 proxies. The curl tool got the
  options called --socks5-gssapi-service and --socks5-gssapi-nec to enable

- Chad Monroe provided the new CURLOPT_TFTP_BLKSIZE option that allows an app
  to set desired block size to use for TFTP transfers instead of the default
  512 bytes.

- The "-no_ticket" option was introduced in Openssl0.9.8j. It's a flag to
  disable "rfc4507bis session ticket support".  rfc4507bis was later turned
  into the proper RFC5077 it seems:

  The enabled extension concerns the session management. I wonder how often
  libcurl stops a connection and then resumes a TLS session. also, sending the
  session data is some overhead. .I suggest that you just use your proposed
  patch (which explicitly disables TICKET).

  If someone writes an application with libcurl and openssl who wants to
  enable the feature, one can do this in the SSL callback.

  Sharad Gupta brought this to my attention. Peter Sylvester helped me decide
  on the proper action.
