- tool_cb_wrt: fix writing to Windows null device NUL
  - Improve console detection.
  Prior to this change WriteConsole could be called to write to a handle
  that may not be a console, which would cause an error. This issue is
  limited to character devices that are not also consoles such as the null
  device NUL.

- [Chris Young brought this change]

  configure: add --with-amissl
  AmiSSL is an Amiga native library which provides a wrapper over OpenSSL.
  It also requires all programs using it to use bsdsocket.library
  directly, rather than accessing socket functions through clib, which
  libcurl was not necessarily doing previously. Configure will now check
  for the headers and ensure they are included if found.

- [Marc Schlatter brought this change]

  http: send payload when (proxy) authentication is done
  The check that prevents payload from sending in case of authentication
  doesn't check properly if the authentication is done or not.
  They're cases where the proxy respond "200 OK" before sending
  authentication challenge. This change takes care of that.

- memdebug: log pointer before freeing its data
  Coverity warned for two potentional "Use after free" cases. Both are false
  positives because the memory wasn't used, it was only the actual pointer
  value that was logged.
  The fix still changes the order of execution to avoid the warnings.

Marcel Raad (12 Mar 2019)
- travis: actually use updated compiler versions
  For the Linux builds, GCC 8 and 7 and clang 7 were installed, but the
  new GCC versions were only used for the coverage build and for building
  nghttp2, while the new clang version was not used at all.
  BoringSSL needs to use the default GCC as it respects CC, but not CXX,
  so it would otherwise pass gcc 8 options to g++ 4.8 and fail.
  Also remove GCC 7, it's not needed anymore.

- travis: update clang to version 7

- [Andre Guibert de Bruet brought this change]

  examples/externalsocket: add missing close socket calls
  .. and for Windows also call WSACleanup since we call WSAStartup.
  The example is to demonstrate handling the socket independently of
  libcurl. In this case libcurl is not responsible for creating, opening
  or closing the socket, it is handled by the application (our example).

Daniel Stenberg (11 Mar 2019)
- multi: removed unused code for request retries
  This code was once used for the non multi-interface using code path, but
  ever since easy_perform was turned into a wrapper around the multi
  interface, this code path never runs.
  Closes #3666

Jay Satiro (11 Mar 2019)
- doh: inherit some SSL options from user's easy handle
  - Inherit SSL options for the doh handle but not SSL client certs,
    SSL ALPN/NPN, SSL engine, SSL version, SSL issuer cert,
    SSL pinned public key, SSL ciphers, SSL id cache setting,
    SSL kerberos or SSL gss-api settings.
  - Fix inheritance of verbose setting.
  - Inherit NOSIGNAL.
  There is no way for the user to set options for the doh (DNS-over-HTTPS)
  handles and instead we inherit some options from the user's easy handle.
  My thinking for the SSL options not inherited is they are most likely
  not intended by the user for the DOH transfer. I did inherit insecure
  because I think that should still be in control of the user.
  Prior to this change doh did not work for me because CAINFO was not
  inherited. Also verbose was set always which AFAICT was a bug (#3660).

  Since it can't be NULL and it makes Coverity believe we lack proper NULL
  checks. Verified by test 659, landed in commit 15401fa886b.

- ssh: loop the state machine if not done and not blocking
  If the state machine isn't complete, didn't fail and it didn't return
  due to blocking it can just as well loop again.
  This addresses the problem with SFTP directory listings where we would
  otherwise return back to the parent and as the multi state machine
  doesn't have any code for using CURLM_CALL_MULTI_PERFORM for as long the
  doing phase isn't complete, it would return out when in reality there
  was more data to deal with.

Jay Satiro (5 Mar 2019)
- multi: support verbose conncache closure handle
  - Change closure handle to receive verbose setting from the easy handle
    most recently added via curl_multi_add_handle.
  The closure handle is a special easy handle used for closing cached
  connections. It receives limited settings from the easy handle most
  recently added to the multi handle. Prior to this change that did not
  include verbose which was a problem because on connection shutdown
  verbose mode was not acknowledged.

- 10-at-a-time.c: fix too long line

- [Arnaud Rebillout brought this change]

  examples: various fixes in ephiperfifo.c
  The main change here is the timer value that was wrong, it was given in
  usecs (ms * 1000), while the itimerspec struct wants nsecs (ms * 1000 *
  1000). This resulted in the callback being invoked WAY TOO OFTEN.
  As a quick check you can run this command before and after applying this
      # shell 1
      ./ephiperfifo 2>&1 | tee ephiperfifo.log
      # shell 2
      echo > hiper.fifo
  Then just compare the size of the logs files.

- threaded-resolver: shutdown the resolver thread without error message
  When a transfer is done, the resolver thread will be brought down. That
  could accidentally generate an error message in the error buffer even
  though this is not an error situationand the transfer would still return
  OK.  An application that still reads the error buffer could find a
  "Could not resolve host: [host name]" message there and get confused.

  Without it set, we would unwillingly triger the "HTTP error before end

- cookies: only save the cookie file if the engine is enabled
  Follow-up to 8eddb8f4259.
  If the cookieinfo pointer is NULL there really is nothing to save.
  Without this fix, we got a problem when a handle was using shared object
  with cookies and is told to "FLUSH" it to file (which worked) and then
  the share object was removed and when the easy handle was closed just
  afterwards it has no cookieinfo and no cookies so it decided to save an
  empty jar (overwriting the file just flushed).
  Test 1905 now verifies that this works.

- easy: fix win32 init to work without CURL_GLOBAL_WIN32
  - Change the behavior of win32_init so that the required initialization
    procedures are not affected by CURL_GLOBAL_WIN32 flag.
  libcurl via curl_global_init supports initializing for win32 with an
  optional flag CURL_GLOBAL_WIN32, which if omitted was meant to stop
  Winsock initialization. It did so internally by skipping win32_init()
  when that flag was set. Since then win32_init() has been expanded to
  include required initialization routines that are separate from
  Winsock and therefore must be called in all cases. This commit fixes
  it so that CURL_GLOBAL_WIN32 only controls the optional win32
  initialization (which is Winsock initialization, according to our doc).
  The only users affected by this change are those that don't pass
  CURL_GLOBAL_WIN32 to curl_global_init. For them this commit removes the
  risk of a potential crash.

  connection_check: restore original conn->data after the check
  - Save the original conn->data before it's changed to the specified
    data transfer for the connection check and then restore it afterwards.
  This is a follow-up to 38d8e1b 2019-02-11.
  It was discovered a month ago that before checking whether to extract a
  dead connection that that connection should be associated with a "live"
  transfer for the check (ie original conn->data ignored and set to the
  passed in data). A fix was landed in 54b201b which did that and also
  cleared conn->data after the check. The original conn->data was not
  restored, so presumably it was thought that a valid conn->data was no
  longer needed.
  Several days later it was discovered that a valid conn->data was needed
  after the check and follow-up fix was landed in bbae24c which partially
  reverted the original fix and attempted to limit the scope of when
  conn->data was changed to only when pruning dead connections. In that
  case conn->data was not cleared and the original conn->data not
  A month later it was discovered that the original fix was somewhat
  correct; a "live" transfer is needed for the check in all cases
  because original conn->data could be null which could cause a bad deref
  at arbitrary points in the check. A fix was landed in 38d8e1b which
  expanded the scope to all cases. conn->data was not cleared and the
  original conn->data not restored.
  A day later it was discovered that not restoring the original conn->data
  may lead to busy loops in applications that use the event interface, and
  given this observation it's a pretty safe assumption that there is some
  code path that still needs the original conn->data. This commit is the
  follow-up fix for that, it restores the original conn->data after the
  connection check.

- escape ':' character
  ':' is interpreted as separator by zsh, so if used as part of the argument
  or option's description it needs to be escaped.

   % curl --reso<TAB>
   % curl -E <TAB>

- update regex to better match curl -h output
  The current regex fails to match '<...>' arguments properly (e.g. those

   Problem 1
  After LOTS of scratching my head, I eventually realized that even when doing
  10 uploads in parallel, sometimes the socket callback to the application that
  tells it what to wait for on the socket, looked like it would reflect the
  status of just the single transfer that just changed state.
  Digging into the code revealed that this was indeed the truth. When multiple
  transfers are using the same connection, the application did not correctly get
  the *combined* flags for all transfers which then could make it switch to READ
  (only) when in fact most transfers wanted to get told when the socket was
   Problem 1b
  A separate but related regression had also been introduced by me when I
  cleared connection/transfer association better a while ago, as now the logic
  couldn't find the connection and see if that was marked as used by more
  transfers and then it would also prematurely remove the socket from the socket
  hash table even in times other transfers were still using it!
   Fix 1
  Make sure that each socket stored in the socket hash has a "combined" action
  field of what to ask the application to wait for, that is potentially the ORed
  action of multiple parallel transfers. And remove that socket hash entry only
  if there are no transfers left using it.
   Problem 2
  The socket hash entry stored an association to a single transfer using that
  socket - and when curl_multi_socket_action() was called to tell libcurl about
  activities on that specific socket only that transfer was "handled".
  This was WRONG, as a single socket/connection can be used by numerous parallel
  transfers and not necessarily a single one.
   Fix 2
  We now store a list of handles in the socket hashtable entry and when libcurl
  is told there's traffic for a particular socket, it now iterates over all
  known transfers using that single socket.

  Curl_slist_append_nodup() returns NULL when it fails to create a new

  new list on top of the old list it would result in a dangling pointer
  and lost memory. Also, in case we hit an allocation failure at some
  point during the conversion, with allocation succeeding again on the

  failure point. Fix by assigning to a temporary list pointer, which can
  be checked (which is the common pattern for slist appending), and free

- travis: enable COPYRIGHTYEAR extended warning
  The extended warning for checking incorrect COPYRIGHTYEAR is quite

  we ensure it's turned on locally for Travis.

- checksrc: add COPYRIGHTYEAR check
  Forgetting to bump the year in the copyright clause when hacking has
  been quite common among curl developers, but a traditional checksrc
  check isn't a good fit as it would penalize anyone hacking on January
  1st (among other things). This adds a more selective COPYRIGHTYEAR
  check which intends to only cover the currently hacked on changeset.
  The check for updated copyright year is currently not enforced on all
  files but only on files edited and/or committed locally. This is due to
  the amount of files which aren't updated with their correct copyright
  year at the time of their respective commit.
  To further avoid running this expensive check for every developer, it
  adds a new local override mode for checksrc where a .checksrc file can
  be used to turn on extended warnings locally.

- openssl: support session resume with TLS 1.3
  Session resumption information is not available immediately after a TLS 1.3
  handshake. The client must wait until the server has sent a session ticket.
  Use OpenSSL's "new session" callback to get the session information and put it
  into curl's session cache. For TLS 1.3 sessions, this callback will be invoked
  after the server has sent a session ticket.
  The "new session" callback is invoked only if OpenSSL's session cache is
  enabled, so enable it and use the "external storage" mode which lets curl manage
  the contents of the session cache.
  A pointer to the connection data and the sockindex are now saved as "SSL extra
  data" to make them available to the callback.
  This approach also works for old SSL/TLS versions and old OpenSSL versions.

  If a !checksrc! disable command specified to ignore zero errors, it was
  still added to the ignore block even though nothing was ignored. While
  there were no blocks ignored that shouldn't be ignored, the processing
  ended with with a warning:
  <filename>:<line>:<col>: warning: Unused ignore: LONGLINE (UNUSEDIGNORE)
   /* !checksrc! disable LONGLINE 0 */
  Fix by instead treating a zero ignore as a a badcommand and throw a
  warning for that one.

- checksrc: enable strict mode and warnings
  Enable strict and warnings mode for checksrc to ensure we aren't missing
  anything due to bugs in the checking code. This uncovered a few things
  which are all fixed in this commit:
  * several variables were used uninitialized
  * several variables were not defined in the correct scope
  * the whitelist filehandle was read even if the file didn't exist
  * the enable_warn() call when a disable counter had expired was passing
    incorrect variables, but since the checkwarn() call is unlikely to hit
    (the counter is only decremented to zero on actual ignores) it didn't
    manifest a problem.

- memory: ensure to check allocation results
  The result of a memory allocation should always be checked, as we may

  wasn't checked for success. In the ftp case, the freeing of the path
  variable is moved ahead of the allocation since there is little point

- vtls: fix ssl version "or later" behavior change for many backends
  - Treat CURL_SSLVERSION_MAX_NONE the same as
    CURL_SSLVERSION_MAX_DEFAULT. Prior to this change NONE would mean use
    the minimum version also as the maximum.
  This is a follow-up to 6015cef which changed the behavior of setting
  the SSL version so that the requested version would only be the minimum
  and not the maximum. It appears it was (mostly) implemented in OpenSSL
  but not other backends. In other words CURL_SSLVERSION_TLSv1_0 used to
  mean use just TLS v1.0 and now it means use TLS v1.0 *or later*.
  Prior to this change CURL_SSLVERSION_MAX_DEFAULT with OpenSSL was
  erroneously treated as always TLS 1.3, and would cause an error if
  OpenSSL was built without TLS 1.3 support.

  ssl: deprecate CURLE_SSL_CACERT in favour of a unified error code

- [Han Han brought this change]

  x509asn1: return CURLE_PEER_FAILED_VERIFICATION on failure to parse cert
  CURLE_PEER_FAILED_VERIFICATION makes more sense because Curl_parseX509
  does not allocate memory internally as its first argument is a pointer
  to the certificate structure. The same error code is also returned by
  Curl_verifyhost when its call to Curl_parseX509 fails so the change
  makes error handling more consistent.

  cookies: support creation-time attribute for cookies
  According to RFC6265 section 5.4, cookies with equal path lengths
  SHOULD be sorted by creation-time (earlier first). This adds a
  creation-time record to the cookie struct in order to make cookie
  sorting more deterministic. The creation-time is defined as the
  order of the cookies in the jar, the first cookie read fro the
  jar being the oldest. The creation-time is thus not serialized
  into the jar. Also remove the strcmp() matching in the sorting as
  there is no lexicographic ordering in RFC6265. Existing tests are

  docs/CURLOPT_WRITEFUNCTION: size is always 1
  For compatibility with `fwrite`, the `CURLOPT_WRITEFUNCTION` callback is
  passed two `size_t` parameters which, when multiplied, designate the
  number of bytes of data passed in. In practice, CURL always sets the
  first parameter (`size`) to 1.
  This practice is also enshrined in documentation and cannot be changed
  in future. The documentation states that the default callback is
  `fwrite`, which means `fwrite` must be a suitable function for this
  purpose. However, the documentation also states that the callback must
  return the number of *bytes* it successfully handled, whereas ISO C
  `fwrite` returns the number of items (each of size `size`) which it
  wrote. The only way these numbers can be equal is if `size` is 1.
  Since `size` is 1 and can never be changed in future anyway, document
  that fact explicitly and let users rely on it.

  auth: pick Bearer authentication whenever a token is available
  So far, the code tries to pick an authentication method only if
  user/password credentials are available, which is not the case for
  Bearer authentictation...
  Signed-off-by: Johannes Schindelin <>

  auth: only ever pick CURLAUTH_BEARER if we *have* a Bearer token
  The Bearer authentication was added to cURL 7.61.0, but there is a
  problem: if CURLAUTH_ANY is selected, and the server supports multiple
  authentication methods including the Bearer method, we strongly prefer
  that latter method (only CURLAUTH_NEGOTIATE beats it), and if the Bearer
  authentication fails, we will never even try to attempt any other
  This is particularly unfortunate when we already know that we do not
  have any Bearer token to work with.
  Such a scenario happens e.g. when using Git to push to Visual Studio
  Team Services (which supports Basic and Bearer authentication among
  other methods) and specifying the Personal Access Token directly in the
  URL (this aproach is frequently taken by automated builds).
  Let's make sure that we have a Bearer token to work with before we
  select the Bearer authentication among the available authentication

  openssl: assume engine support in 1.0.0 or later
  Commit 38203f1585da changed engine detection to be version-based,
  with a baseline of openssl 1.0.1. This does in fact break builds
  with openssl 1.0.0, which has engine support - the configure script
  detects that ENGINE_cleanup() is available - but <openssl/engine.h>
  doesn't get included to declare it.
  According to upstream documentation, engine support was added to
  mainstream openssl builds as of version 0.9.7:
  This commit drops the version test down to 1.0.0 as version 1.0.0d
  is the oldest version I have to test with.

  This was added earlier but appears to have been removed accidentally.
  AFAICT this is very much still an issue.

  configure: fix ssh2 linking when built with a static mbedtls
  The ssh2 pkg-config file could contain the following lines when build
  with a static version of mbedtls:
     Libs: -L${libdir} -lssh2 /xxx/libmbedcrypto.a
     Libs.private: /xxx/libmbedcrypto.a
  This static mbedtls library must be used to correctly detect ssh2
  support and this library must be copied in libcurl.pc otherwise
  compilation of any application (such as upmpdcli) with libcurl will fail
  when trying to found mbedtls functions included in libssh2.  So, replace
  pkg-config --libs-only-l by pkg-config --libs.

  schannel: make CAinfo parsing resilient to CR/LF
  OpenSSL has supported --cacert for ages, always accepting LF-only line
  endings ("Unix line endings") as well as CR/LF line endings ("Windows
  line endings").
  When we introduced support for --cacert also with Secure Channel (or in
  cURL speak: "WinSSL"), we did not take care to support CR/LF line
  endings, too, even if we are much more likely to receive input in that
  form when using Windows.
  Let's fix that.
  Happily, CryptQueryObject(), the function we use to parse the ca-bundle,
  accepts CR/LF input already, and the trailing LF before the END
  CERTIFICATE marker catches naturally any CR/LF line ending, too. So all
  we need to care about is the BEGIN CERTIFICATE marker. We do not
  actually need to verify here that the line ending is CR/LF. Just
  checking for a CR or an LF is really plenty enough.

- curl: show headers in bold
  The feature is only enabled if the output is believed to be a tty.
  -J: There's some minor differences and improvements in -J handling, as
  now J should work with -i and it actually creates a file first using the
  initial name and then *renames* that to the one found in
  Content-Disposition (if any).
  -i: only shows headers for HTTP transfers now (as documented).
  Previously it would also show for pieces of the transfer that were HTTP
  (for example when doing FTP over a HTTP proxy).
  -i: now shows trailers as well. Previously they were not shown at all.
  --libcurl: the CURLOPT_HEADER is no longer set, as the header output is
  now done in the header callback.
