- unit1610: init SSL library before calling SHA256 functions
  
  The SSL library must be initialized (via global initialization) because
  libcurl's SHA256 functions may call SHA256 functions in the SSL library.

  hostip: avoid unused parameter error in Curl_resolv_check
  
  When built without DNS-over-HTTP and without asynchronous resolvers,
  neither the dns nor the data parameters are used.
  
  That is Curl_resolv_check appears to call
  Curl_resolver_is_resolved(data, dns). But,
  with CURL_DISABLE_DOH without CURLRES_ASYNCH, the call is actually
  elided via a macro definition.
  
  This fix resolves the resultant: "unused parameter 'data'" error.

Jay Satiro (21 Feb 2022)
- openssl: check if sessionid flag is enabled before retrieving session
  
  Ideally, Curl_ssl_getsessionid should not be called unless sessionid
  caching is enabled. There is a debug assertion in the function to help
  ensure that. Therefore, the pattern in all vtls is basically:
  
    if(primary.sessionid) {lock(); Curl_ssl_getsessionid(...); unlock();}
  
  There was one instance in openssl.c where sessionid was not checked
  beforehand and this change fixes that.
  
  Prior to this change an assertion would occur in openssl debug builds
  during connection stage if session caching was disabled.

- multi: allow user callbacks to call curl_multi_assign
  
  Several years ago a change was made to block user callbacks from calling
  back into the API when not supported (recursive calls). One of the calls
  blocked was curl_multi_assign. Recently the blocking was extended to the
  multi interface API, however curl_multi_assign may need to be called
  from within those user callbacks (eg CURLMOPT_SOCKETFUNCTION).
  
  I can't think of any callback where it would be unsafe to call
  curl_multi_assign so I removed the restriction entirely.

  bearssl: fix EXC_BAD_ACCESS on incomplete CA cert
  
  - Do not create trust anchor object for a CA certificate until after it
    is processed.
  
  Prior to this change the object was created at state BR_PEM_BEGIN_OBJ
  (certificate processing begin state). An incomplete certificate (for
  example missing a newline at the end) never reaches BR_PEM_END_OBJ
  (certificate processing end state) and therefore the trust anchor data
  was not set in those objects, which caused EXC_BAD_ACCESS.

  bearssl: fix connect error on expired cert and no verify
  
  - When peer verification is disabled use the x509_decode engine instead
    of the x509_minimal engine to parse and extract the public key from
    the first cert of the chain.
  
  Prior to this change in such a case no key was extracted and that caused
  CURLE_SSL_CONNECT_ERROR. The x509_minimal engine will stop parsing if
  any validity check fails but the x509_decode won't.

  schannel: move the algIds array out of schannel.h
  
  This array is only used by the SCHANNEL_CRED struct in the
  schannel_acquire_credential_handle function. It can therefore be kept as
  a local variable. This is a minor update to
  bbb71507b7bab52002f9b1e0880bed6a32834511.
  
  This change also updates the NUM_CIPHERS value to accurately count the
  number of ciphers options listed in schannel.c, which is 47 instead of
  45. It is unlikely that anyone tries to set all 47 values, but if they
  had tried, the last two would not have been set.

Marcel Raad (17 Feb 2022)
- des: fix compile break for OpenSSL without DES
  
  When `USE_OPENSSL` was defined but OpenSSL had no DES support and a
  different crypto library was used for that, `Curl_des_set_odd_parity`
  was called but not defined. This could for example happen on Windows
  and macOS when using OpenSSL v3 with deprecated features disabled.
  
  Use the same condition for the function definition as used at the
  caller side, but leaving out the OpenSSL part to avoid including
  OpenSSL headers.

  EVP_sha256() does not appear in the OpenSSL source before 0.9.7h, and

- md5: refactor for standard compliance
  
  - Wrap OpenSSL / wolfSSL MD5 functions instead of taking their function

  Depending on how curl was built the old way may have used a dllimport
  function address during static initialization, which is not standard
  compliant, resulting in Visual Studio warning C4232 (nonstandard
  extension). Instead the function pointers now point to the wrappers
  which call the MD5 functions.
  
  This change only affects OpenSSL and wolfSSL because calls to other SSL
  libraries' md5 functions were already wrapped. Also sha256.c already
  does this for all SSL libraries.

- tool_findfile: search for a file in the homedir
  
  The homedir() function is now renamed into findfile() and iterates over
  all the environment variables trying to access the file in question
  until it finds it. Last resort is then getpwuid() if
  available. Previously it would first try to find a home directory and if
  that was set, insist on checking only that directory for the file. This
  now returns the full file name it finds.
  
  The Windows specific checks are now done differently too and in this
  order:
  
  1 - %USERPROFILE%
  2 - %APPDATA%
  3 - %USERPROFILE%\\Application Data
  
  The windows order is modified to match how the Windows 10 ssh tool works
  when it searches for .ssh/known_hosts.

- urlapi: provide more detailed return codes
  
  Previously, the return code CURLUE_MALFORMED_INPUT was used for almost
  30 different URL format violations. This made it hard for users to
  understand why a particular URL was not acceptable. Since the API cannot
  point out a specific position within the URL for the problem, this now
  instead introduces a number of additional and more fine-grained error
  codes to allow the API to return more exactly in what "part" or section
  of the URL a problem was detected.
  
  Also bug-fixes curl_url_get() with CURLUPART_ZONEID, which previously
  returned CURLUE_OK even if no zoneid existed.
  
  Test cases in 1560 have been adjusted and extended. Tests 1538 and 1559

  rustls: read of zero bytes might be okay
  
  When we're reading out plaintext from rustls' internal buffers, we might
  get a read of zero bytes (meaning a clean TCP close, including
  close_notify). However, we shouldn't return immediately when that
  happens, since we may have already copied out some plaintext bytes.
  Break out of the loop when we get a read of zero bytes, and figure out
  which path we're dealing with.

  rustls: remove incorrect EOF check
  
  The update to rustls-ffi 0.8.0 changed handling of EOF and close_notify.
  From the CHANGELOG:
  
  > Handling of unclean close and the close_notify TLS alert. Mirroring
  > upstream changes, a rustls_connection now tracks TCP closed state like
  > so: rustls_connection_read_tls considers a 0-length read from its
  > callback to mean "TCP stream was closed by peer."  If that happens
  > before the peer sent close_notify, rustls_connection_read will return
  > RUSTLS_RESULT_UNEXPECTED_EOF once the available plaintext bytes are
  > exhausted. This is useful to protect against truncation attacks. Note:
  > some TLS implementations don't send close_notify. If you are already
  > getting length information from your protocol (e.g. Content-Length in
  > HTTP) you may choose to ignore UNEXPECTED_EOF so long as the number of
  > plaintext bytes was as expected.
  
  That means we don't need to check for unclean EOF in `cr_recv()`,
  because `process_new_packets()` will give us an error if appropriate.

  configure: don't enable TLS when --without-* flags are used
  
  Previously specifying `--without-gnutls` would unexpectedly attempt to
  compile with GnuTLS, effectively interpreting this as
  `--with-gnutls`. This caused a significant amount of confusion when
  `libcurl` was built with SSL disabled since GnuTLS wasn't present.
  
  68d89f24 dropped the `--without-*` options from the configure help, but
  `AC_ARG_WITH` still defines these flags automatically. As
  https://www.gnu.org/software/autoconf/manual/autoconf-2.60/html_node/External-Software.html
  describes, the `action-if-given` is called when the user specifies
  `--with-*` or `--without-*` options.
  
  To prevent this confusion, we make the `--without` flag do the right
  thing by ignoring the value if it set to "no".

  sendf: accept zero-length data in Curl_client_write()
  
  Historically, Curl_client_write() used a length value of 0 as a marker
  for a null-terminated data string. This feature has been removed in
  commit f4b85d2. To detect leftover uses of the feature, a DEBUGASSERT
  statement rejecting a length with value 0 was introduced, effectively
  precluding use of this function with zero-length data.
  
  The current commit removes the DEBUGASSERT and makes the function to
  return immediately if length is 0.
  
  A direct effect is to fix trying to output a zero-length distinguished
  name in openldap.
  
  Another DEBUGASSERT statement is also rephrased for better readability.

- http: set content length earlier
  
  - Make content length (ie download size) accessible to the user in the
    header callback, but only after all headers have been processed (ie
    only in the final call to the header callback).
  
  Background:
  
  For a long time the content length could be retrieved in the header
  callback via CURLINFO_CONTENT_LENGTH_DOWNLOAD_T as soon as it was parsed
  by curl.
  
  Changes were made in 8a16e54 (precedes 7.79.0) to ignore content length
  if any transfer encoding is used. A side effect of that was that
  content length was not set by libcurl until after the header callback
  was called the final time, because until all headers are processed it
  cannot be determined if content length is valid.
  
  This change keeps the same intention --all headers must be processed--
  but now the content length is available before the final call to the
  header function that indicates all headers have been processed (ie
  a blank header).

  hostip: Move allocation to clarify there is no memleak
  
  By just glancing at the code, it looks like there is a memleak if the
  call to Curl_inet_pton() fails. Looking closer, it is clear that the
  call to Curl_inet_pton() can not fail, so the code will never leak
  memory. However, we can make this obvious by moving the allocation
  after the if-statement.

- lib: avoid fallthrough cases in switch statements
  
  Commit b5a434f7f0ee4d64857f8592eced5b9007d83620 inhibits the warning
  on implicit fallthrough cases, since the current coding of indicating
  fallthrough with comments is falling out of fashion with new compilers.
  This attempts to make the issue smaller by rewriting fallthroughs to no
  longer fallthrough, via either breaking the cases or turning switch
  statements into if statements.
  
    lib/content_encoding.c: the fallthrough codepath is simply copied
      into the case as it's a single line.
    lib/http_ntlm.c: the fallthrough case skips a state in the state-
      machine and fast-forwards to NTLMSTATE_LAST. Do this before the
      switch statement instead to set up the states that we actually
      want.
    lib/http_proxy.c: the fallthrough is just falling into exiting the
      switch statement which can be done easily enough in the case.
    lib/mime.c: switch statement rewritten as if statement.
    lib/pop3.c: the fallthrough case skips to the next state in the
      statemachine, do this explicitly instead.
    lib/urlapi.c: switch statement rewritten as if statement.
    lib/vssh/wolfssh.c: the fallthrough cases fast-forwards the state
      machine, do this by running another iteration of the switch
      statement instead.
    lib/vtls/gtls.c: switch statement rewritten as if statement.
    lib/vtls/nss.c: the fallthrough codepath is simply copied into the
      case as it's a single line. Also twiddle a comment to not be
      inside a non-brace if statement.

- cmdline-opts: made the 'Added:' field mandatory
  
  Since "too old" versions are no longer included in the generated man
  page, this field is now mandatory so that it won't be forgotten and then
  not included in the documentation.
  
  Closes #7786

- curl.1: remove mentions of really old version changes
  
  To make the man page more readable, this change removes all references
  to changes in support/versions etc that happened before 7.30.0 from the
  curl.1 output file. 7.30.0 was released on Apr 12 2013. This particular
  limit is a bit arbitrary but was fairly easy to grep for.
  
  It is handled like this: the 'Added' keyword is only used in output if
  it refers to 7.30.0 or later. All occurances of "(Added in $VERSION)" in
  description will be stripped out if the mentioned $VERSION is from
  before 7.30.0. It is therefore important that the "Added in..."
  references are always written exactly like that - and on a single line,
  not split over two.
  
  This change removes about 80 version number references from curl.1, down
  to 138 from 218.

  On connection shutdown, a new TLS session ticket may arrive after the
  SSL session cache has already been destructed. In this case, the new
  SSL session cannot be added to the SSL session cache.
  
  The callers of Curl_ssl_addsessionid() need to know whether the SSL
  session has been added to the cache. If it has not been added, the
  reference counter of the SSL session must not be incremented, or memory
  used by the SSL session must be freed. This is now possible with the new

- cirrus: Add FreeBSD 13.0 job and disable sanitizer build
  
  As alluded to the in the now removed comment, a 13.0 image became
  available and is now ready to be used.
  
  The sanitizer builds were running on the 12.1 image which since has
  been removed from the config, leaving the builds not running at all.
  When enabled it turns out that they don't actually work due to very
  long timeouts in executing the tests, so keep the disabled for now
  but a bit more controlled.

- hostip: Make Curl_ipv6works function independent of getaddrinfo
  
  - Do not assume IPv6 is not working when getaddrinfo is not present.
  
  The check to see if IPv6 actually works is now independent of whether
  there is any resolver that can potentially resolve a hostname to IPv6.
  
  Prior to this change if getaddrinfo() was not found at compile time then
  Curl_ipv6works() would be defined as a macro that returns FALSE.
  
  When getaddrinfo is not found then libcurl is built with CURLRES_IPV4
  defined instead of CURLRES_IPV6, meaning that it cannot do IPv6 lookups
  in the traditional way. With this commit if libcurl is built with IPv6
  support (ENABLE_IPV6) but without getaddrinfo (CURLRES_IPV6), and the
  IPv6 stack is actually working, then it is possible for libcurl to
  resolve IPv6 addresses by using DoH.

- test1565: fix windows build errors
  
  - Use our wait_ms() instead of sleep() since Windows doesn't have the

  - Use a separate variable to keep track of whether the pthread_t thread
    id is valid.
  
  On Windows pthread_t is not an integer type. pthread offers no macro for
  invalid pthread_t thread id, so validity is kept track of separately.

- connect: fix wrong format specifier in connect error string
  
  0842175 (not in any release) used the wrong format specifier (long int)
  for timediff_t. On an OS such as Windows libcurl's timediff_t (usually
  64-bit) is bigger than long int (32-bit). In 32-bit Windows builds the
  upper 32-bits of the timediff_t were erroneously then used by the next
  format specifier. Usually since the timeout isn't larger than 32-bits
  this would result in null as a pointer to the string with the reason for
  the connection failing. On other OSes or maybe other compilers it could
  probably result in garbage values (ie crash on deref).
  
  Before:
  Failed to connect to localhost port 12345 after 1201 ms: (nil)
  
  After:
  Failed to connect to localhost port 12345 after 1203 ms: Connection refused

  docs: make the documentation for --etag-save match the program behaviour
  
  When using curl with the option `--etag-save` I expected it to save the
  ETag without its surrounding quotes, as stated by the documentation in
  the repository and by the generated man pages.
  
  My first endeavour was to fix the program, but while investigating the
  history of the relevant parts, I discovered that curl once saved the
  ETag without the quotes.  This was undone by Daniel Stenberg in commit
  `98c94596f5928840177b6bd3c7b0f0dd03a431af`, therefore I decided that in
  this case the documentation should be adjusted to match the behaviour of
  curl.

  Revert "ftp: Expression 'ftpc->wait_data_conn' is always false"
  
  The reverted commit introduced a logic error in code that was
  correct.
  
  The client using libcurl would notice the error since FTP file
  uploads in active transfer mode would somtimes complete with
  success despite no transfer having been performed and the
  "uploaded" file thus not being on the remote server afterwards.
  
  The FTP server would notice the error because it receives a
  RST on the data connection it has established with the client
  before any data was transferred at all.
  
  The logic error happens if the STOR response from the server have
  arrived by the time ftp_multi_statemach() in the affected code path
  is called, but the incoming data connection have not arrived yet.
  In that case, the processing of the STOR response will cause
  'ftpc->wait_data_conn' to be set to TRUE, contradicting the comment
  in the code. Since 'complete' will also be set, later logic would
  believe the transfer was done.
  
  In most cases, the STOR response will not have arrived yet when
  the affected code path is executed, or the incoming connection will
  also have arrived, and thus the error would not express itself.
  But if the speed difference of the device using libcurl and the
  FTP server is exactly right, the error may happen as often as in
  one out of hundred file transfers.
  
  This reverts commit 49f3117a238b6eac0e22a32f50699a9eddcb66ab.

- http: fix crash in rate-limited upload
  
  - Don't set the size of the piece of data to send to the rate limit if
    that limit is larger than the buffer size that will hold the piece.
  
  Prior to this change if CURLOPT_MAX_SEND_SPEED_LARGE
  (curl tool: --limit-rate) was set then it was possible that a temporary
  buffer used for uploading could be written to out of bounds. A likely
  scenario for this would be a non-trivial amount of post data combined
  with a rate limit larger than CURLOPT_UPLOAD_BUFFERSIZE (default 64k).
  
  The bug was introduced in 24e469f which is in releases since 7.76.0.

  - Check whether a connection has succeded before checking whether it's

    but between checking the timeout, and connecting to the server the
    connection succeeds, we will allow it to go ahead. This is viewed as

- vtls: fix warning due to function prototype mismatch
  
  b09c8ee changed the function prototype. Caught by Visual Studio.

- curl_multibyte: Remove local encoding fallbacks
  
  - If the UTF-8 to UTF-16 conversion fails in Windows Unicode builds then
    no longer fall back to assuming the string is in a local encoding.
  
  Background:
  
  Some functions in Windows Unicode builds must convert UTF-8 to UTF-16 to
  pass to the Windows CRT API wide-character functions since in Windows
  UTF-8 is not a valid locale (or at least 99% of the time right now).
  
  Prior to this change if the Unicode encoding conversion failed then
  libcurl would assume, for backwards compatibility with applications that
  may have written their code for non-Unicode builds, attempt to convert
  the string from local encoding to UTF-16.
  
  That type of "best effort" could theoretically cause some type of
  security or other problem if a string that was locally encoded was also
  valid UTF-8, and therefore an unexpected UTF-8 to UTF-16 conversion
  could occur.
