  libressl: OCSP and intermediate certs workaround no longer needed
  
  lib/vtls/openssl.c has a workaround for a bug with OCSP responses signed
  by intermediate certs, this was fixed in LibreSSL in

- urlglob: fix division by zero
  
  The multiply() function that is used to avoid integer overflows, was
  itself reason for a possible division by zero error when passed a
  specially formatted glob.

- FindWin32CACert: Use a temporary buffer on the stack
  
  Don't malloc() the temporary buffer, and use the correct type:
  SearchPath() works with TCHAR, but SearchPathA() works with char.
  Set the buffer size to MAX_PATH, because the terminating null byte
  is already included in MAX_PATH.

  cmake: Fix inconsistency regarding mbed TLS include directory
  
  Previously, one had to set MBEDTLS_INCLUDE_DIR to make CMake find the
  headers, but the system complained that mbed TLS wasn't found due to
  MBEDTLS_INCLUDE_DIRS (note the trailing s) was not set. This commit
  attempts to fix that.

  examples/multi-uv.c: fix deprecated symbol
  
  Closes #1557

- asyn-ares: s/Curl_expire_latest/Curl_expire

- expire: remove Curl_expire_latest()
  
  With the introduction of expire IDs and the fact that existing timers
  can be removed now and thus never expire, the concept with adding a
  "latest" timer is not working anymore as it risks to not expire at all.
  
  So, to be certain the timers actually are in line and will expire, the
  plain Curl_expire() needs to be used. The _latest() function was added
  as a sort of shortcut in the past that's quite simply not necessary
  anymore.

- test1521: make the code < 80 columns wide

- test1121: use stricter types to work with typcheck-gcc

- typecheck-gcc: allow CURLOPT_STDERR to be NULL too

- test1521: test *all* curl_easy_setopt options
  
  mk-lib1521.pl generates a test program (lib1521.c) that calls
  curl_easy_setopt() for every known option with a few typical values to
  make sure they work (ignoring the return codes).
  
  Some small changes were necessary to avoid asserts and NULL accesses
  when doing this.
  
  The perl script needs to be manually rerun when we add new options.

- updatemanpages.pl: error out on too old git version

Marcel Raad (3 Jun 2017)
- cyassl: define build macros before including ssl.h
  
  cyassl/ssl.h needs the macros from cyassl/options.h, so define them
  before including cyassl/ssl.h the first time, which happens in
  urldata.h.
  This broke the build on Ubuntu Xenial, which comes with WolfSSL 3.4.8
  and therefore redefines the symbols from cyassl/options.h instead of
  including the header.
  
  Closes https://github.com/curl/curl/pull/1536

- mbedtls: make TU-local variable static
  
  mbedtls_x509_crt_profile_fr is only used locally.
  This fixes a missing-variable-declarations warning with clang.

- MD(4|5): silence cast-align clang warning
  
  Unaligned access is on purpose here and the warning is harmless on

  Otherwise, they are removed in the final configure file.
  Also changed sed to "$SED" like in most other calls in this file.

- curl-compilers.m4: fix compiler_num for clang
  
  "clang -dumpversion" always returns "4.2.1", the GCC version that clang
  was initially compatible to. Use "clang -v" instead, which returns the
  actual clang version.

- [Jay Satiro brought this change]

  rand: treat fake entropy the same regardless of endianness
  
  When the random seed is purposely made predictable for testing purposes
  by using the CURL_ENTROPY environment variable, process that data in an
  endian agnostic way so the the initial random seed is the same
  regardless of endianness.
  
  - Change Curl_rand to write to a char array instead of int array.
  
  - Add Curl_rand_hex to write random hex characters to a buffer.

- tool_msgs: remove wrong cast
  
  Commit 481e0de00a9003b9c5220b120e3fc302d9b0932d changed the variable
  type from int to size_t, so don't cast the result of strlen to int
  anymore.

- tftpd: fix signed/unsigned mismatch warnings
  
  alarm's argument is unsigned.

- libtest: fix MinGW-w64 warnings
  
  long is 32 bits while size_t is 64 bits on MinGW-w64, so
  typecheck-gcc.h complains when using size_t for a long option.
  Also, curl_socket_t is unsigned long long rather than int.

- [Alan Jenkins brought this change]

  multi: clarify condition in curl_multi_wait
  
  `if(nfds || extra_nfds) {` is followed by `malloc(nfds * ...)`.
  
  If `extra_fs` could be non-zero when `nfds` was zero, then we have
  `malloc(0)` which is allowed to return `NULL`. But, malloc returning
  NULL can be confusing. In this code, the next line would treat the NULL
  as an allocation failure.
  
  It turns out, if `nfds` is zero then `extra_nfds` must also be zero.
  The final value of `nfds` includes `extra_nfds`.  So the test for
  `extra_nfds` is redundant.  It can only confuse the reader.

- typecheck-gcc: handle function pointers properly
  
  All the callbacks passed to curl_easy_setopt are defined as function
  pointers. The possibility to pass both functions and function pointers
  was handled for the callbacks that typecheck-gcc.h defined as
  compatible, but not for the public callback types themselves.
  
  This makes all compatible callback types defined in typecheck-gcc.h
  function pointers too and checks all functions uniformly with
  _curl_callback_compatible, which handles both functions and function
  pointers.
  
  A symptom of the problem was a warning in tool_operate.c with
  --disable-libcurl-option and without --enable-debug as that file
  passes the callback functions to curl_easy_setopt directly.

  This fixes 3 warnings issued by MinGW:
  1. PR_ImportTCPSocket actually has a paramter of type PROsfd instead of
  PRInt32, which is 64 bits on Windows. Fixed this by including the
  corresponding header file instead of redeclaring the function, which is
  supported even though it is in the private include folder. [1]
  2. In 64-bit mode, size_t is 64 bits while CK_ULONG is 32 bits, so an explicit
  narrowing cast is needed.
  3. Curl_timeleft returns time_t instead of long since commit
  21aa32d30dbf319f2d336e0cb68d3a3235869fbb.

  TLS: Fix switching off SSL session id when client cert is used
  
  Move the sessionid flag to ssl_primary_config so that ssl and proxy_ssl
  will each have their own sessionid flag.
  
  Regression since HTTPS-Proxy support was added in cb4e2be. Prior to that
  this issue had been fixed in 247d890, CVE-2016-5419.

  openssl: fix thread-safety bugs in error-handling
  
  ERR_error_string with NULL parameter is not thread-safe. The library
  writes the string into some static buffer. Two threads doing this at
  once may clobber each other and run into problems. Switch to
  ERR_error_string_n which avoids this problem and is explicitly
  bounds-checked.
  
  Also clean up some remnants of OpenSSL 0.9.5 around here. A number of
  comments (fixed buffer size, explaining that ERR_error_string_n was
  added in a particular version) date to when ossl_strerror tried to
  support pre-ERR_error_string_n OpenSSLs.

  tests: added test for Curl_splaygetbest to unit1309

  multi: fix queueing of pending easy handles
  
  Multi handles repeatedly invert the queue of pending easy handles when
  used with CURLMOPT_MAX_TOTAL_CONNECTIONS. This is caused by a multistep
  process involving Curl_splaygetbest and violates the FIFO property of
  the multi handle.
  This patch fixes this issue by redefining the "best" node in the
  context of timeouts as the "smallest not larger than now", and
  implementing the necessary data structure modifications to do this
  effectively, namely:
   - splay nodes with the same key are now stored in a doubly-linked
     circular list instead of a non-circular one to enable O(1)
     insertion to the tail of the list
   - Curl_splayinsert inserts nodes with the same key to the tail of
     the same list
   - in case of multiple nodes with the same key, the one on the head of
     the list gets selected

  system.h is aimed to replace curlbuild.h at a later point in time when

  curl/system.h determines a data sizes, data types and include file

  recent versions.

- http: do not treat FTPS over CONNECT as HTTPS
  
  If we use FTPS over CONNECT, the TLS handshake for the FTPS control
  connection needs to be initiated in the SENDPROTOCONNECT state, not
  the WAITPROXYCONNECT state.  Otherwise, if the TLS handshake completed
  without blocking, the information about the completed TLS handshake
  would be saved to a wrong flag.  Consequently, the TLS handshake would
  be initiated in the SENDPROTOCONNECT state once again on the same
  connection, resulting in a failure of the TLS handshake.  I was able to
  observe the failure with the NSS backend if curl ran through valgrind.

  http: Fix proxy connection reuse with basic-auth
  
  When using basic-auth, connections and proxy connections
  can be re-used with different Authorization headers since
  it does not authenticate the connection (like NTLM does).
  
  For instance, the below command should re-use the proxy
  connection, but it currently doesn't:
  curl -v -U alice:a -x http://localhost:8181 http://localhost/
    --next -U bob:b -x http://localhost:8181 http://localhost/
  
  This is a regression since refactoring of ConnectionExists()
  as part of: cb4e2be7c6d42ca0780f8e0a747cecf9ba45f151
  
  Fix the above by removing the username and password compare
  when re-using proxy connection at proxy_info_matches().
  
  However, this fix brings back another bug would make curl
  to re-print the old proxy-authorization header of previous
  proxy basic-auth connection because it wasn't cleared.
  
  For instance, in the below command the second request should
  fail if the proxy requires authentication, but would succeed
  after the above fix (and before aforementioned commit):
  curl -v -U alice:a -x http://localhost:8181 http://localhost/
    --next -x http://localhost:8181 http://localhost/
  
  Fix this by clearing conn->allocptr.proxyuserpwd after use
  unconditionally, same as we do for conn->allocptr.userpwd.
  
  Also fix test 540 to not expect digest auth header to be
  resent when connection is reused.

  The character set in POSIX is set by the locale defined by (in
  decreasing order of precedence) the LC_ALL, LC_CTYPE and LANG
  environment variables (CHARSET was used by libidn but not libidn2).
  LC_ALL is cleared to ensure that LC_CTYPE takes effect, but LC_ALL is
  not used to set the locale to ensure that other parts of the locale
  aren't overridden.  Since there doesn't seem to be a cross-platform way
  of specifying a UTF-8 locale, and not all systems may support UTF-8, a
  <precheck> is used to skip the test if UTF-8 can't be verified to be
  available.  Test 1035 was also converted to UTF-8 for consistency, as
  the actual character set used there is irrelevant to the test.
  
  This patch uses a different UTF-8 locale than the last attempt, namely
  en_US.UTF-8. This one has been verified on 7 different Linux and BSD
  distributions and is more complete and usable than the locale UTF-8 (on
  at least some systems).

  cmdline-opts/gen.pl: Open input files in CRLF mode
  
  On Windows it's possible to have input files with CRLF line endings and
  a perl that defaults to LF line endings (eg msysgit). Currently that
  results in generator output of mixed line endings of CR, LF and CRLF.
  
  This change fixes that issue in the most succinct way by opening the
  files in :crlf text mode even when the perl being used does not default
  to that mode. (On operating systems that don't have a separate text mode
  it's essentially a no-op.) The output continues to be in the perl's
  native line ending.

  schannel: fix wildcard cert name validation on Win CE
  
  Fixes a few issues in manual wildcard cert name validation in
  schannel support code for Win32 CE:
  - when comparing the wildcard name to the hostname, the wildcard
    character was removed from the cert name and the hostname
    was checked to see if it ended with the modified cert name.
    This allowed cert names like *.com to match the connection
    hostname. This violates recommendations from RFC 6125.
  - when the wildcard name in the certificate is longer than the
    connection hostname, a buffer overread of the connection
    hostname buffer would occur during the comparison of the
    certificate name and the connection hostname.

  proxy: Support HTTPS proxy and SOCKS+HTTP(s)
  
  * HTTPS proxies:
  
  An HTTPS proxy receives all transactions over an SSL/TLS connection.
  Once a secure connection with the proxy is established, the user agent
  uses the proxy as usual, including sending CONNECT requests to instruct
  the proxy to establish a [usually secure] TCP tunnel with an origin
  server. HTTPS proxies protect nearly all aspects of user-proxy
  communications as opposed to HTTP proxies that receive all requests
  (including CONNECT requests) in vulnerable clear text.
  
  With HTTPS proxies, it is possible to have two concurrent _nested_
  SSL/TLS sessions: the "outer" one between the user agent and the proxy
  and the "inner" one between the user agent and the origin server
  (through the proxy). This change adds supports for such nested sessions
  as well.
  
  A secure connection with a proxy requires its own set of the usual SSL
  options (their actual descriptions differ and need polishing, see TODO):
  
    --proxy-cacert FILE        CA certificate to verify peer against
    --proxy-capath DIR         CA directory to verify peer against
    --proxy-cert CERT[:PASSWD] Client certificate file and password
    --proxy-cert-type TYPE     Certificate file type (DER/PEM/ENG)
    --proxy-ciphers LIST       SSL ciphers to use
    --proxy-crlfile FILE       Get a CRL list in PEM format from the file
    --proxy-insecure           Allow connections to proxies with bad certs
    --proxy-key KEY            Private key file name
    --proxy-key-type TYPE      Private key file type (DER/PEM/ENG)
    --proxy-pass PASS          Pass phrase for the private key
    --proxy-ssl-allow-beast    Allow security flaw to improve interop
    --proxy-sslv2              Use SSLv2
    --proxy-sslv3              Use SSLv3
    --proxy-tlsv1              Use TLSv1
    --proxy-tlsuser USER       TLS username
    --proxy-tlspassword STRING TLS password
    --proxy-tlsauthtype STRING TLS authentication type (default SRP)
  
  All --proxy-foo options are independent from their --foo counterparts,
  except --proxy-crlfile which defaults to --crlfile and --proxy-capath
  which defaults to --capath.
  
  Curl now also supports %{proxy_ssl_verify_result} --write-out variable,
  similar to the existing %{ssl_verify_result} variable.
  
  Supported backends: OpenSSL, GnuTLS, and NSS.
  
  * A SOCKS proxy + HTTP/HTTPS proxy combination:
  
  If both --socks* and --proxy options are given, Curl first connects to
  the SOCKS proxy and then connects (through SOCKS) to the HTTP or HTTPS
  proxy.
  
  TODO: Update documentation for the new APIs and --proxy-* options.
  Look for "Added in 7.XXX" marks.

  Curl_http2_switched can be called like:

  .. and prior to this change memcpy was then called like:
  
  memcpy(dest, NULL, 0)

  Fixes #1083

- testcurl.1: fix the URL to the autobuild summary

- testcurl.1: update URLs

- INSTALL: converted to markdown => INSTALL.md
  
  Also heavily edited for content. Removed lots of old cruft that we added
  like 10+ years ago that is likely incorrect by now.
  
  Also removed INSTALL.devcpp for same reason.

  configure: Check for other variants of the -m*os*-version-min flags
  
  In addition to -miphoneos-version-min, the same version can be set
  using -mios-version-min. And for WatchOS and TvOS, there's
  -mwatchos-version-min and -mtvos-version-min.

- configure: set min version flags for builds on mac
  
  This helps building binaries that can work on multiple macOS versions.

  Fixes #1069

- curl_multi_add_handle: set timeouts in closure handles
  
  The closure handle only ever has default timeouts set. To improve the
  state somewhat we clone the timeouts from each added handle so that the
  closure handle always has the same timeouts as the most recently added
  easy handle.
  
  Fixes #739

- configure/CURL_CHECK_FUNC_POLL: disable poll completely on mac
  
  ... so that the same libcurl build easier can run on any version.
  
  Follow-up to issue #1057

- RELEASE-NOTES: synced with f36f8c14551efc6772

- test14xx: fixed --libcurl output tests again after 8e8afa82cbb

- s/cURL/curl
  
  The tool was never called cURL, only the project. But even so, we have
  more and more over time switched to just use lower case.

- polarssl: indented code, removed unused variables

- polarssl: reduce #ifdef madness with a macro

- polarssl: fix unaligned SSL session-id lock

- Curl_polarsslthreadlock_thread_setup: clear array at init
  
  ... since if it fails to init the entire array and then tries to clean
  it up, it would attempt to work on an uninitialized pointer.

- curl: set INTERLEAVEDATA too
  
  As otherwise the callback could be called with a NULL pointer when RTSP
  data is provided.

- gopher: properly return error for poll failures

- select: switch to macros in uppercase
  
  Curl_select_ready() was the former API that was replaced with
  Curl_select_check() a while back and the former arg setup was provided
  with a define (in order to leave existing code unmodified).
  
  Now we instead offer SOCKET_READABLE and SOCKET_WRITABLE for the most
  common shortcuts where only one socket is checked. They're also more
  visibly macros.

- select: use more proper macro-looking names
  
  ... so that it becomes more obvious in the code what is what. Also added
  a typecast for one of the calculations.

- Curl_socket_check: add extra check to avoid integer overflow

- maketgz: make it support "only" generating version info
  
  ... to allow you to update the local repository with the given version
  number data.

- url: skip to-be-closed connections when pipelining (follow-up)
  
  - Change back behavior so that pipelining is considered possible for
  connections that have not yet reached the protocol level.
  
  This is a follow-up to e5f0b1a which had changed the behavior of
  checking if pipelining is possible to ignore connections that had
  'bits.close' set. Connections that have not yet reached the protocol
  level also have that bit set, and we need to consider pipelining
  possible on those connections.

  smb: properly check incoming packet boundaries
  
  Not all reply messages were properly checked for their lengths, which
  made it possible to access uninitialized memory (but this does not lead
  to out of boundary accesses).
  
  Closes #1052

- test557: verify printf() with 128 and 129 arguments

- mprintf: return error on too many arguments
  
  128 arguments should be enough for everyone

- ftp: fix Curl_ftpsendf()
  
  ... it no longer takes printf() arguments since it was only really taken
  advantage by one user and it was not written and used in a safe
  way. Thus the 'f' is removed from the function name and the proto is
  changed.
  
  Although the current code wouldn't end up in badness, it was a risk that
  future changes could end up springf()ing too large data or passing in a
  format string inadvertently.

- formpost: avoid silent snprintf() truncation
  
  The previous use of snprintf() could make libcurl silently truncate some
  input data and not report that back on overly large input, which could
  make data get sent over the network in a bad format.
  
  Example:
  
   $ curl --form 'a=b' -H "Content-Type: $(perl -e 'print "A"x4100')"

  builds. This now adapts if the funtion isn't there and builds libcurl
  without NTLM support if so.
  
  Fixes #1004

- CODE_STYLE: fix long-line guideline
  
  - Change maximum allowed line length from 80 to 79.

- CODE_STYLE: add column alignment section
  
  Note that since the added examples are for column alignment I had to
  encapsulate with ~~~c markdown to preserve their alignment.

- cmake: fix curl-config --static-libs
  
  The `curl-config --static-libs` command should not output paths like
  -l/usr/lib/libssl.so, instead print the absolute path without `-l`.
  
  This also removes the confusing message "Static linking is broken" which
  was printed because curl-config --static-libs was disfunctional even
  though the static libcurl.a library works properly.

- http: refuse to pass on response body with NO_NODY was set
  
  ... like when a HTTP/0.9 response comes back without any headers at all
  and just a body this now prevents that body from being sent to the
  callback etc.
  
  Adapted test 1144 to verify.
  
  Fixes #973

- CMake: Don't build unit tests if private symbols are hidden
  
  This only excludes building unit tests from default build ( 'all' Make
  target or "Build Solution" in VisualStudio). The projects and Make
  targets will still be generated and shown in supporting IDEs.
  
  Fixes https://github.com/curl/curl/issues/981
  Reported-by: Randy Armstrong
  
  Closes https://github.com/curl/curl/pull/990

- CMake: Try to (un-)hide private library symbols
  
  Detect support for compiler symbol visibility flags and apply those
  according to CURL_HIDDEN_SYMBOLS option.
  It should work true to the autotools build except it tries to unhide
  symbols on Windows when requested and prints warning if it fails.

- openssl: fix bad memory free (regression)
  
  ... by partially reverting f975f06033b1. The allocation could be made by
  OpenSSL so the free must be made with OPENSSL_free() to avoid problems.

  Fixes #1005

- http2: support > 64bit sized uploads
  
  ... by making sure we don't count down the "upload left" counter when the
  uploaded size is unknown and then it can be allowed to continue forever.

- errors: new alias CURLE_WEIRD_SERVER_REPLY (8)
  
  Since we're using CURLE_FTP_WEIRD_SERVER_REPLY in imap, pop3 and smtp as
  more of a generic "failed to parse" introduce an alias without FTP in
  the name.
  
  Closes https://github.com/curl/curl/pull/975

  mk-ca-bundle.pl: use SHA256 instead of SHA1
  
  This hash is used to verify the original downloaded certificate bundle
  and also included in the generated bundle's comment header. Also
  rename related internal symbols to algorithm-agnostic names.

  openssl: fix CURLINFO_SSL_VERIFYRESULT
  
  CURLINFO_SSL_VERIFYRESULT does not get the certificate verification
  result when SSL_connect fails because of a certificate verification
  error.
  
  This fix saves the result of SSL_get_verify_result so that it is
  returned by CURLINFO_SSL_VERIFYRESULT.
  
  Closes https://github.com/curl/curl/pull/995

  darwinssl: test for errSecSuccess in PKCS12 import rather than noErr (#993)
  
  While noErr and errSecSuccess are defined as the same value, the API
  documentation states that SecPKCS12Import() returns errSecSuccess if
  there were no errors in importing. Ensure that a future change of the
  defined value doesn't break (however unlikely) and be consistent with
  the API docs.

  openssl: Fix compilation with OPENSSL_API_COMPAT=0x10100000L
  
  With OPENSSL_API_COMPAT=0x10100000L (OpenSSL 1.1 API), the cleanup
  functions are unavailable (they're no-ops anyway in OpenSSL 1.1). The
  replacements for SSL_load_error_strings, SSLeay_add_ssl_algorithms, and
  OpenSSL_add_all_algorithms are called automatically [1][2]. SSLeay() is
  now called OpenSSL_version_num().
