Version 7.21.5 (17 Apr 2011)

Daniel Stenberg (17 Apr 2011)
- base64.c: removed wrong comment

- INTERNALS: clean up
  
  Clarified the release procedure

- TODO-RELEASE: push the remaining ones to next release
  
  As we're closing in on the release, I give up on the remaining ones but
  I leave them in here for now to try to fix for next release.
  
  I removed the 281 issue about warnings from the statical analyzer scans,
  as they seem to be mostly false positives at this point.

  src/Makefile.b32: updates
  
  * Rename the object object directory from 'objs' to 'BCC_obj' to be in
   sync with my previous patch for lib/Makefile.b32.
  
  * Turn off these warnings to keep the build totally silent (with CBuilder-6
   that is).
    -w-inl    8026 Functions X are not expanded inline.
    -w-pia   8060 Possibly incorrect assignment
    -w-pin  8061 Initialization is only partially bracketed
   (same added in src/Makefile.b32)
  
  * $(MKDIR) and $(RMDIR) have been replaced with the shell-commands 'md'
   and 'rd'. When having MingW/Msys programs 'mkdir.exe' and 'rmdir.exe' in
  $PATH, this confuses Borland's make and the result (the cleaning etc.) would
   not be as expected.
  
  * Removed the preprocessing step; no need for PP_CMD and the .int files.
   curl.exe builds fine w/o and the makefile gets simpler.
  
  * Added a target for creating a compressed hugehelp.c if WITH_ZLIB is  defined.
  It assumes groff, gzip and perl is available if such an "advanced"  users
  requests it. Okay? BTW. My groff and Perl needs unix-slashes ('/').
   Other perls should handle both forms ('/' and '\').

  lib/Makefile.b32: updates
  
  * Rename the object object directory from 'objs' to 'BCC_obj'. I feel
   it should be named properly. Ref. Makefile.Watcom where it's called
   'WC_Win32.obj'.
  
  * Turn off these warnings to keep the build totally silent (with CBuilder-6
   that is).
    -w-inl    8026 Functions X are not expanded inline.
    -w-pia   8060 Possibly incorrect assignment
    -w-pin  8061 Initialization is only partially bracketed
  
  I'm sure the warnings could be fixed the "proper" way or with some added
  "#pragma" statements. But that just clutters the sources IMHO.
  
  * $(MKDIR) and $(RMDIR) have been replaced with the shell-commands 'md'
   and 'rd'. When having MingW/Msys programs 'mkdir.exe' and 'rmdir.exe' in
  $PATH, this confuses Borland's make and the result (the cleaning etc.) would
   not be as expected.
  
  * Added a ".path.int = $(OBJDIR)" to tell make where the $(PREPROCESSED)
   files are. Why we need the preprocess step in the fist place is beyond me
  (Yang?). But I'll leave that for now.

  -275 - Introduce a way to avoid sending USER for FTP connections
  -288 - bug 3219997 curl rtmp request curl: (55) select/poll returned error
  
  This problem is rather an autoconf bug with little user interest and it

Dan Fandrich (5 Apr 2011)
- Changed some nonportable types

- Don't list NTLM in curl-config when HTTP is disabled
  
  Also, fixed Curl_proxyCONNECT() stub with HTTP disabled.

- Fixed compatibility macro CURLE_URL_MALFORMAT_USER

Daniel Stenberg (5 Apr 2011)
- return code cleanup: build, init and run-time errors
  
  Stop the abuse of CURLE_FAILED_INIT as return code for things not being
  init related by introducing two new return codes:
  
  CURLE_NOT_BUILT_IN and CURLE_UNKNOWN_OPTION
  
  CURLE_NOT_BUILT_IN replaces return code 4 that has been obsoleted for
  several years. It is used for returning error when something is
  attempted to be used but the feature/option was not enabled or
  explictitly disabled at build-time. Getting this error mostly means that
  libcurl needs to be rebuilt.
  
  CURLE_FAILED_INIT is now saved and used strictly for init
  failures. Getting this problem means something went seriously wrong,
  like a resource shortage or similar.
  
  CURLE_UNKNOWN_OPTION is the option formerly known as
  CURLE_UNKNOWN_TELNET_OPTION (and the old name is still present,
  separately defined to be removed in a very distant future). This error
  code is meant to be used to return when an option is given to libcurl
  that isn't known. This problem would mostly indicate a problem in the
  program that uses libcurl.

- FTP+proxy: macrofied functions when proxy disabled
  
  In my attempts to reduce #ifdefs in code, the SOCKS functions are now
  macros when libcurl is built without proxy support and therefore the FTP
  code could avoid some #ifs.

Dan Fandrich (4 Apr 2011)
- Added http_proxy.c to the Symbian build files

Daniel Stenberg (4 Apr 2011)
- http-proxy: move proxy code to http_proxy.c
  
  The new http_proxy.* files now host HTTP proxy specific code (500+ lines
  moved out from http.c), and as a consequence there is a macro introduced
  for the Curl_proxyCONNECT() function so that code can use it without
  actually supporting proxy (or HTTP) in builds.

- disable cookies: remove ifdefs, move code
  
  1 - make sure to #define macros for cookie functions in the cookie
  header when cookies are disabled to avoid having to use #ifdefs in code
  using those functions.
  
  2 - move cookie-specific code to cookie.c and use the functio
  conditionally as mentioned in (1).
  
  net result: 6 #if lines removed, and 9 lines of code less

- multi: shorten lines
  
  We keep them less than 80 columns

- multi: conn goes bad when data change
  
  Within multi_socket when conn is used as a shorthand, data could be
  changed and multi_runsingle could modify the connectdata struct to deal
  with. This bug has not been included in a public release.
  
  Using 'conn' like that turned out to be ugly. This change is a partial
  revert of commit f1c6cd42f474df59.

  support and enables it.

- RELEASE-NOTES: synced with 11c2db2aa2a

- fix: re-use of bound connections
  
  When asked to bind the local end of a connection when doing a request,
  the code will now disqualify other existing connections from re-use even
  if they are connected to the correct remote host.
  
  This will also affect which connections that can be used for pipelining,
  so that only connections that aren't bound or bound to the same
  device/port you're asking for will be considered.

- symbols-in-versions: make test 1119 happy

- rtsp: move protocol code to dedicated file
  
  The RTSP-specific function for checking for "dead" connection is better
  located in rtsp.c. The code using this is now written without #ifdefs as
  the function call is instead turned into a macro (in rtsp.h) when RTSP
  is disabled.

- MAIL-ETIQUETTE: intro and spam
  
  Added a little generic info section about the lists and a section about
  how to deal with trolls and spam on the lists.

- TODO-RELEASE: 1 fixed, 1 notabug
  
  Fixed:
  
  271 - fix the IPv6-working probing to only exist at one place in the code and
        only get done once
  
  A problem not repeatable and no proper recipe given and therefore simply
  removed for now until we hear something else:
  
  282 - 100 Continue responses should return the "final" HTTP response code:
        "Getting the HTTP response code following a 100 Continue"

- ipv6: only probe once
  
  Move ipv6-functional-probe into a single function that is used from all
  places that need to know.
  
  Make the probe function store the result in a static variable so that
  subsequent invokes just returns the previous result and won't have to
  probe again.

- headers: more copyright headers added

- MAIL-ETIQUETTE: how to behave
  
  This is a new documentation for the source tree. This information has
  been present since a long time at
  http://curl.haxx.se/mail/etiquette.html but now it is put into a plain
  text version too for wider distribution. The web version will be
  automatically generated from this source document.

Julien Chaffraix (21 Mar 2011)
- progress: don't print the last update on a separate line.
  
  Curl_posttransfer is called too soon to add the final new line.
  Moved the new line logic to pgrsDone as there is no more call to

- retry-request: rewind if data was sent
  
  When libcurl sends a HTTP request on a re-used connection and detects it
  being closed (ie no data at all was read from it), it is important to
  rewind if any data in the request was sent using the read callback or
  was read from file, as otherwise the retried request will be broken.

- nss: do not ignore value of CURLOPT_SSL_VERIFYPEER
  
  When NSS-powered libcurl connected to a SSL server with
  CURLOPT_SSL_VERIFYPEER equal to zero, NSS remembered that the peer
  certificate was accepted by libcurl and did not ask the second time when
  connecting to the same server with CURLOPT_SSL_VERIFYPEER equal to one.
  
  This patch turns off the SSL session cache for the particular SSL socket
  if peer verification is disabled.  In order to avoid any performance
  impact, the peer verification is completely skipped in that case, which
  makes it even faster than before.

- configure: stop using the deprecated AM_INIT_AUTOMAKE syntax

- protocol handler cleanup: SSL awareness
  
  As a follow-up to commit 8831000bc0: don't assume that the SSL powered
  protocol alternatives are available.

- ldap: use the new protocol handler setup
  
  Use the new flags field and stop using the old protocol defines.

- TODO-RELEASE: add and remove issues
  
  Removed a fixed issue, added five new existing ones and clarified one of
  the previous ones.

- protocols: use CURLPROTO_ internally
  
  The PROT_* set of internal defines for the protocols is no longer
  used. We now use the same bits internally as we have defined in the
  public header using the CURLPROTO_ prefix. This is for simplicity and
  because the PROT_* prefix was already used duplicated internally for a
  set of KRB4 values.
  
  The PROTOPT_* defines were moved up to just below the struct definition
  within which they are used.

- protocol handler: added flags field
  
  The protocol handler struct got a 'flags' field for special information
  and characteristics of the given protocol.
  
  This now enables us to move away central protocol information such as
  CLOSEACTION and DUALCHANNEL from single defines in a central place, out
  to each protocol's definition. It also made us stop abusing the protocol
  field for other info than the protocol, and we could start cleaning up
  other protocol-specific things by adding flags bits to set in the
  handler struct.
  
  The "protocol" field connectdata struct was removed as well and the code
  now refers directly to the conn->handler->protocol field instead. To
  make things work properly, the code now always store a conn->given
  pointer that points out the original handler struct so that the code can
  learn details from the original protocol even if conn->handler is
  modified along the way - for example when switching to go over a HTTP
  proxy.

  mk-ca-bundle.pl: Only download if modified
  
  Only download and convert the certdata to the ca-bundle.crt if Mozilla
  changed the data
  
  The Perl LWP module (which in a bit of a circular reference is used by
  mk-ca-bundle.pl) is now indirectly using this script. I made this small
  tweak to make it easier to automatically maintain the generated
  ca-bundle.crt file in version control.

- SSH: add protocol lock direction
  
  Some protocols have to call the underlying functions without regard to
  what exact state the socket signals. For example even if the socket says
  "readable", the send function might need to be called while uploading,
  or vice versa. This is the case for libssh2 based protocols: SCP and
  SFTP and we now introduce a define to set those protocols and we make
  the multi interface code aware of this concept.
  
  This is another fix to make test 582 run properly.

- state: add missing state to debug table
  
  As a new state recently was added to the IMAP state machine it has to be
  in the array of names as well as otherwise libcurl crashes when a debug
  version runs...

- test 582: enabled again
  
  Commit ca37692bf43b5ef should now hopefully make it run

- ssh_statemach_act: set cselect for sftp upload
  
  For uploads we want to use the _sending_ function even when the socket
  turns out readable as the underlying libssh2 sftp send function will
  deal with both accordingly. This is what the cselect_bits magic is for.
  
  Fixes test 582.

  CURL_CHECK_FUNC_RECVFROM: android/bionic fix
  
  recvfrom in bionic (the android libc) deviates from POSIX and uses a
  const in the 5th argument ("const struct sockaddr *") so the check now
  tests for that as well.

- test582: enabled

- PROT_CLOSEACTION: added SFTP and SCP
  
  Both SFTP and SCP are protocols that need to shut down stuff properly
  when the connection is about to get torned down. The primary effect of
  not doing this shows up as memory leaks (when using SCP or SFTP with the
  multi interface).
  
  This is one of the problems detected by test 582.

- readwrite_upload: stop upload at file size
  
  As we know how much to send, we can and should stop once we've sent that
  much data as it avoids having to rely on other mechanisms to detect the
  end.
  
  This is one of the problems detected by test 582.
  
  Reported by: Henry Ludemann <misc@hl.id.au>

- sftp upload: expire to advance state machine
  
  When using the multi_socket API to do SFTP upload, it is important that
  we set a quick expire when leaving the SSH_SFTP_UPLOAD_INIT state as
  there's nothing happening on the socket so there's no read or write to
  wait for, but the next libssh2 API function needs to be called to get
  the ball rolling.
  
  This is one of the problems detected by test 582.

  multi: close connection on timeout
  
  After a request times out, the connection wasn't properly closed and
  prevented to get re-used, so subsequent transfers could still mistakenly
  get to use the previously aborted connection.

- multi: better failed connect treatment
  
  When failing to connect the protocol during the CURLM_STATE_PROTOCONNECT
  state, Curl_done() has to be called with the premature flag set TRUE as
  for the pingpong protocols this can be important.
  
  When Curl_done() is called with premature == TRUE, it needs to call
  Curl_disconnect() with its 'dead_connection' argument set to TRUE as
  well so that any protocol handler's disconnect function won't attempt to
  use the (control) connection for anything.
  
  This problem caused the pingpong protocols to fail to disconnect when
  STARTTLS failed.

  CURLE_TLSAUTH_FAILED: removed
  
  On second thought, I think CURLE_TLSAUTH_FAILED should be eliminated. It
  was only being raised when an internal error occurred while allocating
  or setting the GnuTLS SRP client credentials struct. For TLS
  authentication failures, the general CURLE_SSL_CONNECT_ERROR seems
  appropriate; its error string already includes "passwords" as a possible
  cause. Having a separate TLS auth error code might also cause people to
  think that a TLS auth failure means the wrong username or password was
  entered, when it could also be a sign of a man-in-the-middle attack.

  Add angle brackets to addresses in easy SMTP examples, as for smtp-multi example.

- cookies: tricked dotcounter fixed
  
  Providing multiple dots in a series in the domain field (domain=..com) could
  trick the cookie engine to wrongly accept the cookie believing it to be
  fine. Since the tailmatching would then match all .com sites, the cookie would
  then be sent to all of them.
  
  The code now requires at least one letter between each dot for them to be
  counted. Edited test case 61 to verify this.

- multi: connect fail => use next IP address
  
  When using the multi interface and connecting to a host name that
  resolves to multiple IP addresses, there was no logic that made it
  continue to the next IP if connecting to the first address times

- smtp-multi: put recipient within <brackets>
  
  Even if libcurl might to do it for us, it is more correct.

- ossl_seed: no more RAND_screen
  
  RAND_screen() is slow, not thread-safe and not needed anymore since OpenSSL

- 7.21.4: version bump

- axtls_connect: allow connect without peer verification
  
  The SSL_SERVER_VERIFY_LATER bit in the ssl_ctx_new() call allows the

  then the "data->set.ssl.verifypeer" option works.

- axTLS: allow "default" SSL version as well
  
  When no explicit version is selected we should try to use whatever is
  best for us, and in the axTLS case that means TLSv1.

  Removed odd backslashes at some line endings

- urldate: undef hideous memory defines

  ossl_connect_common: detect connection re-use
  
  ossl_connect_common() now checks whether or not 'struct
  connectdata->state' is equal 'ssl_connection_complete' and if so, will
  return CURLE_OK with 'done' set to 'TRUE'. This check prevents
  ossl_connect_common() from creating a new ssl connection on an existing
  ssl session which causes openssl to fail when it tries to parse an
  encrypted TLS packet since the cipher data was effectively thrown away
  when the new ssl connection was created.

- gnutls->handshake: improved timeout handling
  
  When no timeout is set, we call the socket_ready function with a timeout

  solved by this fix, as this fix only makes the more proper error get

  version the scanned code requires.

- security: Pass the right parameter to init.
  
  init is expecting app_data. Passing it the struct connecdata would make

Daniel Stenberg (11 Nov 2010)
- HTTP Auth: Add CURLAUTH_ONLY
  
  This is a meta symbol. OR this value together with a single specific
  auth value to force libcurl to probe for un-restricted auth and if not,
  only that single auth algorithm is acceptable.
  
  For example you can use CURLAUTH_DIGEST|CURLAUTH_ONLY to make libcurl
  first probe for what method to use, but yet only consider Digest to be
  acceptable.
  
  Using _only_ CURLAUTH_DIGEST without the CURLAUTH_ONLY field, will make
  libcurl explicitly use Digest right away and not do any probing.

- ip_version: moved to connection struct
  
  The IP version choice was previously only in the UserDefined struct
  within the SessionHandle, but since we sometimes alter that option
  during a request we need to have it on a per-connection basis.
  
  I also moved more "init conn" code into the allocate_conn() function
  which is designed for that purpose more or less.

  My copy and paste job was a little too much copy and I missed to adjust

- CURLOPT_RESOLVE: added
  
  CURLOPT_RESOLVE is a new option that sends along a curl_slist with
  name:port:address sets that will populate the DNS cache with entries so
  that request can be "fooled" to use another host than what otherwise
  would've been used. Previously we've encouraged the use of Host: for
  that when dealing with HTTP, but this new feature has the added bonus
  that it allows the name from the URL to be used for TLS SNI and server
  certificate name checks as well.
  
  This is a first change. Surely more will follow to make it decent.

  save metadata to extended file attributes
  
  It is often convinient to track back the source of a once downloaded
  file; this patch makes curl store the source URL and other metadata
  alongside the retrieved file by using the extended attributes (if
  supported by the file system and enabled by --xattr).

- test: remove test 580
  
  Test 580 is removed again for two reasons:
  
  1) Some compilers aren't satisfied by just a data variable called 'test'
  when first.o wants a function called 'test'. The Solaris compiler says
  "ld: warning: symbol `test' has differing types:" while the AIX compiler
  downright rejects it.
  
  2) Test case 1119 that was added after this test is way more complete
  and cover everything test 580 does and more without introducing the same
  problems.

- certcheck: use the custom Host: name for checks
  
  If you use a custom Host: name in a request to a SSL server, libcurl
  will now use that given name when it verifies the server certificate to
  be correct rather than using the host name used in the actual URL.

- SNI: simplify the custom host name use
  
  The redirect check is already done at the position where the customhost
  field is assigned so there's no point in doing that a second time.

- host: get the custom Host: name more genericly
  
  When given a custom host name in a Host: header, we can use it for
  several different purposes other than just cookies, so we rename it and
  use it for SSL SNI etc.

- runtests: allow tests written as perl scripts
  
  If a command is set type="perl", it can now specify a perl program that will
  be run instead of an ordinary curl or built tool.
  
  A perl test automatically disables memory and valgrind debugging.

- symbol-scan: verifies symbols-in-versions
  
  This new script scans for all enums and #defines used by the curl/curl.h
  and curl/multi.h headers. Then it reads all symbols mentioned in
  symbols-in-vesions and make sure that there's no entries missing in
  there. It then proceeds to verify that the entries that
  symbols-in-vesions mentions but aren't found in the sources are truly
  documented as removed.
  
  This script is used in the new test case 1119

- symbols-in-versions: added 119 missing symbols
  
  I've developed a script I call symbol-scan.pl that scans the curl.h and
  multi.h header files and compare the symbols it finds in there with the
  symbols symbols-in-versions documents and outputs a report on the
  differences.  Using this I've dug through the history to fill up
  symbols-in-versions with all the symbols my script found mismatches for.
  
  I will commit symbol-scan.pl separatly and think of a way to put it to
  use in the build/tests so that we from now on will get this in-sync
  check automatically.

- Added mk580.pl to the tar ball

Daniel Stenberg (2 Nov 2010)
- symbols-in-versions: added missing symbols

- ignore: lib580.c is generated by mk580.pl

- test: added test 580 - verifies symbols-in-versions
  
  The new perl script mk580.pl generates a C table in a fresh source file
  named lib580.c and if that compiles fine we know that the file
  docs/libcurl/symbols-in-versions at least doesn't include any symbols
  that are misspelled.
  
  An additional feature would be to somehow scan curl/curl.h and compare
  with symbols-in-versions to see if there are symbols missing.

- SSH: use libssh2_session_handshake()
  
  In libssh2 1.2.8, libssh2_session_handshake() replaces
  libssh2_session_startup() to fix the previous portability problem with
  the socket type that was too small for win64 and thus easily could cause
  crashes and more.

- SSH: avoid using the libssh2_ prefix
  
  It is a bad idea to use the public prefix used by another library and
  now we realize that libssh2 introduces a symbol in the upcoming version
  1.2.8 that conflicts with our static function named libssh2_free.

- formdata: provide error message
  
  When failing to build form post due to an error, the code now does a
  proper failf(). Previously libcurl would report an error like "failed
  creating formpost data" when a file wasn't possible to open which was
  not easy for users to figure out.
  
  I also lower cased a function name to be named more curl-style and
  removed some unnecessary code.

- URL-parsing: consider ? a divider
  
  The URL parser got a little stricter as it now considers a ? to be a
  host name divider so that the slightly sloppier URLs work too. The
  problem that made me do this change was the reported problem with an URL
  like: www.example.com?email=name@example.com This form of URL is not
  really a legal URL (due to the missing slash after the host name) but is
  widely accepted by all major browsers and libcurl also already accepted
  it, it was just the '@' letter that triggered the problem now.
  
  The side-effect of this change is that now libcurl no longer accepts the
  ?  letter as part of user-name or password when given in the URL, which
  it used to accept (and is tested in test 191). That letter is however
  mentioned in RFC3986 to be required to be percent encoded since it is
  used as a divider.

- SFTP: more ignoring negative file sizes
  
  As the change in 5f0ae7a0626cbe709 added a precaution against negative
  file sizes that for some reason managed to get returned, this change now
  introduces the same check at the second place in the code where the file
  size from the libssh2 stat call is used.
  
  This check might not be suitable for a 32 bit curl_off_t, but libssh2.h
  assumes long long to work and to be 64 bit so I believe such a small
  curl_off_t will be very unlikely to occur in the wild.

- krb5-gssapi: Removed a memory leak in krb5_auth.
  
  We forgot to release the buffer passed to gss_init_sec_context.
  
  The previous logic was difficult to read as we were reusing the same

  logic in 2 variables to better underline who needs to be released.
  Also made the code break at 80 lines.

  kr5_auth missed a final 'return' statement. This is not an error in

  Remove a leak seen on Kerberos/MIT (gss_OID is copied internally and
  we were leaking it). Now we just pass NULL as advised in RFC2744.
  
  |tmp| was never set back to buf->data.
  
  Cleaned up Curl_sec_end to take into account failure in Curl_sec_login
  (where conn->mech would be NULL but not conn->app_data or
  conn->in_buffer->data).

- security.c: Remove Curl_sec_fflush_fd.
  
  The current implementation would make us send wrong data on a closed
  socket. We don't buffer our data so the method can be safely removed.

- security.c: We should always register the socket handler.
  
  Following a change in the way socket handler are registered, the custom
  recv and send method were conditionaly registered.
  We need to register them everytime to handle the ftp security
  extensions.
  
  Re-added the clear text handling in sec_recv.

- security.c: Fix Curl_sec_login after rewrite.
  
  Curl_sec_login was returning the opposite result that the code in ftp.c
  was expecting. Simplified the return code (using a CURLcode) so to see
  more clearly what is going on.

- security.c: Readd the '\n' to the infof() calls.
  
  They are not automatically added and make the output of the verbose

  LDAP: Support for tunnelling queries through HTTP proxy
  
  As of curl-7.21.1 tunnelling ldap queries through HTTP Proxies is not
  supported. Actually if --proxytunnel command-line option (or equivalent
  CURLOPT_HTTPPROXYTUNNEL) is used for ldap queries like
  ldap://ldap.my.server.com/... You are unable to successfully execute the
  query. In facts ldap_*_bind is executed directly against the ldap server
  and proxy is totally ignored. This is true for both openLDAP and
  Microsoft LDAP API.
  
  Step to reproduce the error:
  Just launch "curl --proxytunnel --proxy 192.168.1.1:8080
  ldap://ldap.my.server.com/dc=... "
  
  This fix adds an invocation to Curl_proxyCONNECT against the provided
  proxy address and on successful "CONNECT" it tunnels ldap query to the
  final ldap server through the HTTP proxy. As far as I know Microsoft
  LDAP APIs don't permit tunnelling in any way so the patch provided is
  for OpenLDAP only.  The patch has been developed against OpenLDAP 2.4.23
  and has been tested with Microsoft ISA Server 2006 and works properly
  with basic, digest and NTLM authentication.

- timeout: use the correct start value as offset
  
  Rodric provide an awesome recipe that proved libcurl didn't timeout at
  the requested time - it instead often timed out at [connect time] +
  [timeout time] instead of the documented and intended [timeout time]
  only. This bug was due to the code using the wrong base offset when
  comparing against "now". I could also take the oppurtinity to simplify
  the code by properly using of the generic help function for this:
  Curl_timeleft.
  
  Reported by: Rodric Glaser
  Bug: http://curl.haxx.se/bug/view.cgi?id=3061535

- Curl_timeleft: avoid returning "no timeout" by mistake
  
  As this function uses return code 0 to mean that there is no timeout, it
  needs to check that it doesn't return a time left value that is exactly
  zero. It could lead to libcurl doing an extra 1000 ms select() call and
  thus not timing out as accurately as it should.
  
  I fell over this bug when working on the bug 3061535 but this fix does
  not correct that problem alone, although this is a problem that needs to
  be fixed.

- multi: don't do extra expire calls for the connection
  
  The timeout is set for the connect phase already at the start of the
  request so we should not add a new one, and we MUST not set expire to 0

- Link curl and the test apps with -lrt explicitly when necessary
  
  When curl calls a function from that library then it needs to
  explicitly link to the library instead of piggybacking on
  libcurl's own dependency.  Without this, GNU ld with the
  --no-add-needed flag fails when linking (which Fedora now does
  by default).

- multi: fixes for timing out handles
  
  Add a timeout check for handles in the state machine so that they will
  timeout in all states disregarding what actions that may or may not
  happen.
  
  Fixed a bug in socket_action introduced recently when looping over timed
  out handles: it wouldn't assign the 'data' variable and thus it wouldn't
  properly take care of handles.
  
  In the update_timer function, the code now checks if the timeout has
  been removed and then it tells the application. Previously it would
  always let the remaining timeout(s) just linger to expire later on.

- threaded resolver: no more expire 0 calls
  
  Curl_expire() set to 0 expires ALL timeouts so it should only be called
  if we truly and really want to remove all timeouts for the handle.

- resolve_server: simplify code
  
  Make use of the helper function Curl_timeleft() instead of duplicating
  code.

- multi: make sure the next timeout is used when one expires
  
  Each easy handle has a list of timeouts, so as soon as the main timeout
  for a handle expires, we must make sure to get the next entry from the
  list and re-add the handle to the splay tree.
  
  This was attempted previously but was done poorly in my commit
  232ad6549a68450.

  curl_multi_timeout().

- cmdline: make -F type= accept ;charset=
  
  The -F option allows some custom parameters within the given string, and

  field. However, the use of semicolons like that made it not work fine if
  you specified one within the content-type, like for:
  "name=daniel;type=text/plain;charset=UTF-8"
  ... as the second one would be seen as a separator and "charset" is no
  parameter curl knows anything about so it was just silently discarded.
  
  The new logic now checks if the semicolon and following keyword looks
  like a parameter it knows about and if it isn't it is assumed to be
  meant to be used within the content-type string itself.
  
  I modified test case 186 to verify that this works as intended.

- Added mk-ca-bundle.vbs script.
  
  The script works exactly same as the Perl one except for one thing:
  when the text descriptions generated with openssl are included then
  the md5 fingerprints are missing; seems openssl has either a bug or
  a feature which prints the md5 fingerprint output to stdout instead
  of writing them to specified file; this script could here do the same
  as what the Perl scripr does (redirect stdout into file) but this
  makes the script take up double the time because it needs to launch
  cmd.exe 140 times (fo each openssl call). So I think for now we just
  ommit the md5 fingerprints, and see if openssl will be fixed.

- THANKS: added contributors from 7.21.1

- multi: two fixes done

- multi: use timeouts properly for MAX_RECV/SEND_SPEED
  
  When detecting that the send or recv speed, the multi interface changes
  state to TOOFAST and previously there was no timeout set that would
  force a recheck but it would rely on the application to somehow call
  libcurl anyway. This now sets a timeout for a suitable future time to
  check again if the average transfer speed is then below the threshold
  again.

- multi: support timeouts
  
  Curl_expire() is now expanded to hold a list of timeouts for each easy
  handle. Only the closest in time will be the one used as the primary
  timeout for the handle and will be used for the splay tree (which sorts
  and lists all handles within the multi handle).
  
  When the main timeout has triggered/expired, the next timeout in time
  that is kept in the list will be moved to the main timeout position and
  used as the key to splay with. This way, all timeouts that are set with
  Curl_expire() internally will end up as a proper timeout. Previously any
  Curl_expire() that set a _later_ timeout than what was already set was
  just silently ignored and thus missed.
  
  Setting Curl_expire() with timeout 0 (zero) will cancel all previously
  added timeouts.
  
  Corrects known bug #62.

- Curl_llist_insert_next: allow insertion first in the list
  
  When we specify the "insert after" entry as NULL, this function now
  inserts the new entry first in the list.

- multi: make curl_multi_info_read perform O(1)
  
  Instead of looping over all attached easy handles, this now keeps a list
  of messages in the multi handle. It allows curl_multi_info_read() to
  perform O(1) no matter how many easy handles that are handled. This is
  of importance since this function may be polled very frequently by apps
  using the multi interface.

- runtests: clear old setenv remainders before test

  When the progress callback is called during the TCP connection, an error
  return would accidentally not abort the operation as intended but would
  instead be counted as a failure to connect to that particular IP and
  libcurl would just continue to try the next. I made singleipconnect()
  and trynextip() return CURLcode properly.

  like tested in test 1084 and test 1085.

  The var %MAKEFLAGS is only set in 3 cases: if set as environment

  somewhat odd FTP check in parse_remote_port() and instead converted it
  to a better and more generic 'slash_removed' struct field. Checking the
  ->protocol field isn't right since when an FTP:// URL is sent over a
  HTTP proxy, the protocol is HTTP but the URL was handled by the FTP code
  and thus slash_removed is set TRUE for this case.

  libcurl, the return codes are different for such situations and then the
  curl tool failed to consider it for retrying.

- warning: silence a win64 compiler warning
  
  conversion from 'size_t' to 'curl_socklen_t', possible loss of data
  
  Reported by: Adam Light

- KNOWN_BUG: The SOCKET type in Win64 is 64 bits
  
  The SOCKET type in Win64 is 64 bits large (and thus so is curl_socket_t
  on that platform), and long is only 32 bits. It makes it impossible for
  curl_easy_getinfo() to return a socket properly with the
  CURLINFO_LASTSOCKET option as for all other operating systems.

- smtp_connect: always provide host name buffer
  
  Previously the host name buffer was only used if gethostname() exists,
  but since we converted that into a curl private function that function
  always exists and will be used so the buffer needs to exist for all
  cases/systems.

- sethostname: avoid including unistd.h to duck for warnings

- sethostname: ISO C does not allow extra `;' outside of a function

- [Kamil Dudka brought this change]

  NTLM tests: boost coverage by forcing the hostname
  
  A shared library tests/libtest/.libs/lihostname.so is preloaded in NTLM
  test-cases to override the system implementation of gethostname().  It
  makes it possible to test the NTLM authentication for exact match, and
  this way test the implementation of MD4 and DES.
  
  If LD_PRELOAD doesn't work, a debug build willl also workk as debug
  builds are now made to prefer a specific environment variable and will
  then return that content as host name instead of the actual one.
  
  Kamil wrote the bulk of this, Daniel Stenberg polished it.

- Added a comment with an alternate idea to avoid the backslash line contination character.

- Changed comparison to match size_t var type.

- Removed unused vars to avoid compiler warnings.

- Make Watcom makefiles use Makefile.inc to reduce future maintainance.
  
  lib/Makefile.Watcom works fine already, for src/Makefile.Watcom we

- Watcom makefiles overhaul.
  
  - make both libcurl and curl makefiles use register calling convention
    (previously libcurl had stack calling convention).
  - added include paths to the Watcom headers so its no longer required
    to set the environment vars for this.
  - added -wcd=201 to supress compiler warning about unreachable code.
  - use macros for all tools, and removed dependency on GNU tools like rm.
  - make ipv6 and debug builds controlable via env vars and so make them
    optional instead of default.
  - commented WINLDAPAPI and WINBERAPI since they broke with OW 1.8, and
    it seems they're not needed (anymore?).
  - added rule for hugehelp.c.cvs so that it will be created when not
    already exist - this is required for building from a release tarball
    since there we have no hugehelp.c.cvs, thus compilation broke.
  - removed C_ARG creation from lib/Makefile.Watcom and use CFLAGS
    directly as done too in src/Makefile.Watcom - this has the benefit
    that we will see all active cflags and defines during compile.
  - added LINK-ARG to src/Makefile.Watcom in order to better control
    linker input.
  - a couple of other minor makefile tweaks here and there ...
  - added largefile support for Watcom builds to config-win32.h. Not yet
    tested if it really works, but should since Win32 supports it.

  ftp: response timeout bug in "quote" sending

- [Jeff Pohlmeyer brought this change]

  remote-header-name: chop filename at next semicolon

  Content-Disposition: attachment; filename=file.txt; modification-date=...
  
  This fix chops the filename off at the next semicolon, if there is one.

- --retry: access violation with URL part sets continued
  
  When getting multiple URLs, curl didn't properly reset the byte counter
  after a successful transfer so if the subsequent transfer failed it
  would wrongly use the previous byte counter and behave badly (segfault)
  because of that. The code assumes that the byte counter and the 'stream'
  pointer is well in synch.

  multi: fix condition that remove timers before trigger
  
  curl_multi perform has two phases: run through every easy handle calling
  multi_runsingle and remove expired timers (timer removal).
  
  If a small timer (e.g. 1-10ms) is set during multi_runsingle, then it's
  possible that the timer has passed by when the timer removal runs. The
  timer which was just added is then removed. This will potentially cause
  the timer list to be empty and cause the next call to curl_multi_timeout
  to return -1. Ideally, curl_multi_timeout should return 0 in this case.
  
  One way to fix this is to move the struct timeval now = Curl_tvnow(); to
  the top of curl_multi_perform. The change does that.

  upload: Avoid infinite loop when checking for auth bits
  
  The test would loop forever if authtype bit 0 wasn't set.

- upload: warn users trying to upload from stdin with anyauth
  
  Since uploading from stdin is very likely to not work with anyauth and
  its multi-phase probing for what authentication to actually use, alert
  the user about it. Multi-phase negotiate almost certainly will involve
  sending data and thus libcurl will need to rewind the stream to send
  again, and it cannot do that with stdin.

- http: don't enable chunked during authentication negotiations
  
  As mentioned in bug report #2956968, the HTTP code wouldn't send the
  first empty chunk during the auth negotiation phase of the HTTP request
  sending, so the server would wait for data to come and libcurl would
  wait for data to arrive... I've made the code not enable chunked
  encoding until the auth negotiation is done and thus this scenario
  doesn't occur anymore.

- --libcurl: list the tricky options instead of using [REMARK]
  
  I think the [REMARK] and commented function calls cluttered the code a
  bit too much and made the generated code ugly to read. Now we instead
  track the remarks one specially and just lists them at the end of the
  generated code more as additional information.

- curl: avoid setting libcurl options to its default
  
  it makes the --libcurl output easier to follow.

- --libcurl: hide setopt() calls setting default options
  
  And additionally, don't show function or object pointers actual value
  since they make no sense to anyone. Show 'functionpointer' and
  'objectpointer' instead.

- --libcurl: use *_LARGE options with typecasted constants
  
  In the generated code --libcurl makes, all calls to curl_easy_setopt()
  that use *_LARGE options now have the value typecasted to curl_off_t, so
  that it works correctly for 32bit systems with 64bit curl_off_t type.

- multi: CURLINFO_LASTSOCKET doesn't work after remove_handle
  
  When curl_multi_remove_handle() is called and an easy handle is returned
  to the connection cache held in the multi handle, then we cannot allow
  CURLINFO_LASTSOCKET to extract it since that will more or less encourage
  that the user uses the socket while it can get used by libcurl again.
  
  Without this fix, we'd get a segfault in Curl_getconnectinfo() trying to
  dereference the NULL pointer in 'data->state.connc'.

- http_ntlm: add support for NSS
  
  When configured with '--without-ssl --with-nss', NTLM authentication
  now uses NSS crypto library for MD5 and DES.  For MD4 we have a local
  implementation in that case.  More details are available at
  https://bugzilla.redhat.com/603783
  
  In order to get it working, curl_global_init() must be called with
  CURL_GLOBAL_SSL or CURL_GLOBAL_ALL.  That's necessary because NSS needs
  to be initialized globally and we do so only when the NSS library is
  actually required by protocol.  The mentioned call of curl_global_init()
  is responsible for creating of the initialization mutex.
  
  There was also slightly changed the NSS initialization scenario, in
  particular, loading of the NSS PEM module.  It used to be loaded always
  right after the NSS library was initialized.  Now the library is
  initialized as soon as any SSL or NTLM is required, while the PEM module
  is prevented from being loaded until the SSL is actually required.

- multi_socket: re-use of same socket without notifying app
  
  When a hostname resolves to multiple IP addresses and the first one
  tried doesn't work, the socket for the second attempt may get dropped on
  the floor, causing the request to eventually time out. The issue is that
  when using kqueue (as on mac and bsd platforms) instead of select, the
  kernel removes the first fd from kqueue when it is closed (in trynextip,
  connect.c:503). Trynextip() then goes on to open a new socket, which
  gets assigned the same number as the one it just closed. Later in
  multi.c, socket_cb is not called because the fd is already in
  multi->sockhash, so the new socket is never added to kqueue.
  
  The correct fix is to ensure that socket_cb is called to remove the fd
  when trynextip() closes the socket, and again to re-add it after
  singleipsocket(). I'm not sure how to cleanly do that, but the attached
  patch works around the problem in an admittedly kludgy way by delaying
  the close to ensure that the newly-opened socket gets a different fd.
  
  Daniel's added comment: I didn't spot a way to easily do a nicer fix so
  I've proceeded with Ben's patch.

  OpenSSL: fix spurious SSL connection aborts
  
  Was seeing spurious SSL connection aborts using libcurl and
  OpenSSL. I tracked it down to uncleared error state on the
  OpenSSL error stack - patch attached deals with that.
  
  Rough idea of problem:
  
  Code that uses libcurl calls some library that uses OpenSSL but
  don't clear the OpenSSL error stack after an error.
  
  ssluse.c calls SSL_read which eventually gets an EWOULDBLOCK from
  the OS. Returns -1 to indicate an error
  
  ssluse.c calls SSL_get_error. First thing, SSL_get_error calls
  ERR_get_error to check the OpenSSL error stack, finds an old
  error and returns SSL_ERROR_SSL instead of SSL_ERROR_WANT_READ or
  SSL_ERROR_WANT_WRITE.
  
  ssluse.c returns an error and aborts the connection
  
  Solution:
  
  Clear the openssl error stack before calling SSL_* operation if
  we're going to call SSL_get_error afterwards.
  
  Notes:
  
  This is much more likely to happen with multi because it's easier
  to intersperse other calls to the OpenSSL library in the same
  thread.

- multi_socket: handles timer inaccuracy better for timeouts
  
  Igor Novoseltsev reported a problem with the multi socket API and
  using timeouts and timers. It boiled down to a problem with
  libcurl's use of GetTickCount() interally to figure out the
  current time, while Igor's own application code used another
  function call.
  
  It made his app call the socket API timeout function a bit
  _before_ libcurl would consider the timeout to trigger, and that
  could easily lead to timeouts or stalls in the app. It seems
  GetTickCount() in general often has no better resolution than
  16ms and switching to the alternative function
  QueryPerformanceCounter has its share of problems:
  http://www.virtualdub.org/blog/pivot/entry.php?id=106
  
  We address this problem by simply having libcurl treat timers
  that already has occured or will occur within 40ms subject for
  treatment. I'm confident that there are other implementations and
  operating systems with similarly in accurate timer functions so
  it makes sense to have applied generically and I don't believe we
  sacrifice much by adding a 40ms inaccuracy on these timeouts.

  curl_fnmatch: Use int not bool when function returns int
  
  bool in curl internals is unsigned char and should not be used
  to receive return value from functions returning int - this fails
  when using IBM VisualAge and Tru64 compilers.

- TFTP: send legal timeout value
  
  Eric Mertens posted bug #3003705: when we made TFTP use the
  correct timeout option when sent to the server (fixed May 18th
  2010) it became obvious that libcurl used invalid timeout values
  (300 by default while the RFC allows nothing above 255). While of
  course it is obvious that as TFTP has worked thus far without
  being able to set timeout at all, just removing the setting
  wouldn't make any difference in behavior. I decided to still keep
  it (but fix the problem) as it now actually allows for easier
  (future) customization of the timeout.

  at 16 bits so the comparisons and outputs were done wrong. I
  added a macro do make sure it gets done right.

- OpenSSL: multi interface handshake could hang
  
  John-Mark Bell filed bug #3000052 that identified a problem (with
  an associated patch) with the OpenSSL handshake state machine
  when the multi interface is used:
  
  Performing an https request using a curl multi handle and using
  select or epoll to wait for events results in a hang. It appears
  that the cause is the fix for bug #2958179, which makes
  ossl_connect_common unconditionally return from the step 2 loop
  when fetching from a multi handle.
  
  When ossl_connect_step2 has completed, it updates
  connssl->connecting_state to ssl_connect_3. ossl_connect_common
  will then return to the caller, as a multi handle is in
  use. Eventually, the client code will call curl_multi_fdset to
  obtain an updated fdset to select or epoll on. For https
  requests, curl_multi_fdset will cause https_getsock to be called.
  https_getsock will only return a socket handle if the
  connecting_state is ssl_connect_2_reading or
  ssl_connect_2_writing.  Therefore, the client will never obtain a
  valid fdset, and thus not drive the multi handle, resulting in a
  hang.

  it didn't properly ignore the response body of the 30X response
  if that response was using compressed Content-Encoding!

- git: how to write a fine commit message

- findtool: file name as a full path requires a slash
  
  Kalle Vahlman's patch applied a while ago broke how the findtool
  function searches for tools, as it would always check if "$file"
  was present first, which thus made the bad assumption that a file
  in the current directory would be a match.
  
  I noticed when it found 'libtool' in the current directory but
  libtoolize is not there, which confused the script.

Hacki (8 May 2010)
- moved vars into conditional since seems that winsock implementation doesnt use them.

Daniel Stenberg (7 May 2010)
- multi interface: missed storing connection time
  
  Dirk Manske reported a regression. When connecting with the multi
  interface, there were situations where libcurl wouldn't store
  connect time correctly as it used to (and is documented to) do.
  
  Using his fine sample program we could repeat it, and I wrote up
  test case 573 using that code. The problem does not easily show
  itself using the local test suite though.
  
  The fix, also as suggested by Dirk, is a bit on the ugly side as
  it adds yet another call to Curl_verboseconnect() and setting the
  TIMER_CONNECT time.  That situation is subject for some closer
  inspection in the future.

- verboseconnect: so the verbose checking within the function
  
  As the function is used more than once and libcurl can be built
  without it, do the conditional check within the verboseconnect()
  function itself.

- changelogs: split the I/O handling

  sendrecv: split the I/O handling into private handler
  
  Howard Chu brought the bulk work of this patch that properly
  moves out the sending and recving of data to the parts of the
  code that are properly responsible for the various ways of doing
  so.
  
  Daniel Stenberg assisted with polishing a few bits and fixed some
  minor flaws in the original patch.
  
  Another upside of this patch is that we now abuse CURLcodes less
  with the "magic" -1 return codes and instead use CURLE_AGAIN more
  consistently.

  PolarSSL: initial support added
  
  This is Hoi-Ho Chan's patch with some minor fixes by me. There

- INTERNALS: tftp is decent now, ldap is not
  
  It's not quite fair to list TFTP is a "crappy" member of the
  libcurl family so I removed its mentioning.

- changelog: mention Ben Greear's telnet work

- [Ben Greear brought this change]

  telnet: Allow programatic use of telnet.
  
  The main change is to allow input from user-specified methods,
  when they are specified with CURLOPT_READFUNCTION.
  All calls to fflush(stdout) in telnet.c were removed, which makes
  using 'curl telnet://foo.com' painful since prompts and other data
  are not always returned to the user promptly.  Use
  'curl --no-buffer telnet://foo.com' instead.  In general,
  the user should have their CURLOPT_WRITEFUNCTION do a fflush
  for interactive use.
  
  Also fix assumption that reading from stdin never returns < 0.
  Old code could crash in that case.
  
  Call progress functions in telnet main loop.

- SSL_RECV: EOF is not an error here
  
  The recent overhaul of the SSL recv function made this treat a
  zero returned from gnutls_record_recv() as an error, and this
  caused our HTTPS test cases to fail. We leave it to upper layer
  code to detect if an EOF is a problem or not.

- [Paul Howarth brought this change]

  configure: GSSAPI detection on ancient Linux distros
  
  On some ancient distributions such as RHEL-3, <gssapi/gssapi_krb5.h> needs
  to be processed after <gssapi/gssapi.h>, but does not include it itself.
  This patch checks for <gssapi/gssapi.h> first and then includes it
  in the test for <gssapi/gssapi_krb5.h>, resolving the problem.
  
  Without the patch, <gssapi/gssapi_krb5.h> is "present but cannot be
  compiled".

- resolvers: no more using AI_CANONNAME
  
  No resolver anymore needs to use AI_CANONNAME and do reverse
  lookups.  We should work hard to avoid having code that relies on
  it.

- KRB5: use given host name instead of reverse lookup'ed name
  
  This code would previously use dns_entry->addr->ai_canonname
  instead of the given host name, which caused us grief and
  problems since not all our resolver options do the reverse lookup
  and I would also guess that it caused problems with KRB5/GSS with
  virtual name-based hosts. Now the host name from the URL is used.

  it for such requests!
