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
  updated to match.
  
  Closes #2524

Marcel Raad (31 Aug 2018)
- Don't use Windows path %PWD for SSH tests
  
  All these tests failed on Windows because something like
  sftp://%HOSTIP:%SSHPORT%PWD/
  expanded to
  sftp://127.0.0.1:1234c:/msys64/home/bla/curl
  and then curl complained about the port number ending with a letter.
  
  Use the original POSIX path instead of the Windows path created in
  checksystem to fix this.
  
  Closes https://github.com/curl/curl/pull/2920

  As uintptr_t and HANDLE are always the same size, this warning is
  harmless. Just silence it using an intermediate uintptr_t variable.

schannel: client certificate store opening fix
  
  1) Using CERT_STORE_OPEN_EXISTING_FLAG ( or CERT_STORE_READONLY_FLAG )
  while opening certificate store would be sufficient in this scenario and
  less-demanding in sense of required user credentials ( for example,
  IIS_IUSRS will get "Access Denied" 0x05 error for existing CertOpenStore
  call without any of flags mentioned above ),
  
  2) as 'cert_store_name' is a DWORD, attempt to format its value like a
  string ( in "Failed to open cert store" error message ) will throw null
  pointer exception
  
  3) adding GetLastError(), in my opinion, will make error message more
  useful.
  
  Bug: https://curl.haxx.se/mail/lib-2018-08/0198.html
  
  Closes #2909

- [Leonardo Taccari brought this change]

gopher: Do not translate `?' to `%09'
  
  Since GOPHER support was added in curl `?' character was automatically
  translated to `%09' (`\t').
  
  However, this behaviour does not seems documented in RFC 4266 and for
  search selectors it is documented to directly use `%09' in the URL.
  Apart that several gopher servers in the current gopherspace have CGI
  support where `?' is used as part of the selector and translating it to
  `%09' often leads to surprising results.
  
  Closes #2910

Marcel Raad (23 Aug 2018)
- cookie tests: treat files as text
  
  Fixes test failures because of wrong line endings on Windows.

Daniel Stenberg (23 Aug 2018)
- libcurl-thread.3: expand somewhat on the NO_SIGNAL motivation
  
  Multi-threaded applictions basically MUST set CURLOPT_NO_SIGNAL to 1L to
  avoid the risk of getting a SIGPIPE.
  
  Either way, a multi-threaded application that uses libcurl/openssl needs
  to have a signhandler for or ignore SIGPIPE on its own.
  
  Based on discussions in #2800
  Closes #2904

- http2: abort the send_callback if not setup yet
  
  When Curl_http2_done() gets called before the http2 data is setup all
  the way, we cannot send anything and this should just return an error.
  
  Detected by OSS-Fuzz
  Bug: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10012

- http2: remove four unused nghttp2 callbacks
  
  Closes #2903

- x509asn1: use FALLTHROUGH
  
  ... as no other comments are accepted since 014ed7c22f51463

Marcel Raad (21 Aug 2018)
- test1148: disable if decimal separator is not point
  
  Modifying the locale with environment variables doesn't work for native
  Windows applications. Just disable the test in this case if the decimal
  separator is something different than a point. Use a precheck with a
  small C program to achieve that.
  
  Closes https://github.com/curl/curl/pull/2786

- Enable more GCC warnings
  
  This enables the following additional warnings:
  -Wold-style-definition
  -Warray-bounds=2 instead of the default 1
  -Wformat=2, but only for GCC 4.8+ as Wno-format-nonliteral is not
   respected for older versions
  -Wunused-const-variable, which enables level 2 instead of the default 1
  -Warray-bounds also in debug mode through -ftree-vrp
  -Wnull-dereference also in debug mode through
   -fdelete-null-pointer-checks
  
  Closes https://github.com/curl/curl/pull/2747

- curl-compilers: enable -Wimplicit-fallthrough=4 for GCC
  
  This enables level 4 instead of the default level 3, which of the
  currently used comments only allows /* FALLTHROUGH */ to silence the
  warning.
  
  Closes https://github.com/curl/curl/pull/2747

- curl-compilers: enable -Wbad-function-cast on GCC
  
  This warning used to be enabled only for clang as it's a bit stricter
  on GCC. Silence the remaining occurrences and enable it on GCC too.
  
  Closes https://github.com/curl/curl/pull/2747

- configure: conditionally enable pedantic-errors
  
  Enable pedantic-errors for GCC >= 5 with --enable-werror. Before GCC 5,
  pedantic-errors was synonymous to -Werror=pedantic [0], which is still
  the case for clang [1]. With GCC 5, it became complementary [2].
  
  Also fix a resulting error in acinclude.m4 as main's return type was
  missing, which is illegal in C99.

vtls: reinstantiate engine on duplicated handles
  
  Handles created with curl_easy_duphandle do not use the SSL engine set

  name in the internal url state and setting the engine from its name
  inside curl_easy_duphandle.

CMake: CMake config files are defining CURL_STATICLIB for static builds
  
  This change allows to use the CMake config files generated by Curl's

- ssh-libssh: reduce excessive verbose output about pubkey auth
  
  The verbose message "Authentication using SSH public key file" was
  printed each time the ssh_userauth_publickey_auto() was called, which
  meant each time a packet was transferred over network because the API
  operates in non-blocking mode.
  
  This patch makes sure that the verbose message is printed just once
  (when the authentication state is entered by the SSH state machine).

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 <johannes.schindelin@gmx.de>
  Closes #2754

- [Johannes Schindelin brought this change]

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
  method.
  
  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
  methods.

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:
  https://github.com/openssl/openssl/blob/master/README.ENGINE
  
  This commit drops the version test down to 1.0.0 as version 1.0.0d

  themselves instead; while replicating the ciphersuite as specified by
  OpenSSL would have been preferable, I found no way in the SChannel API
  to do so.
  
  To use this from the commandline, you need to pass the names of contants
  defining the desired algorithms. For example, curl --ciphers
  "CALG_SHA1:CALG_RSA_SIGN:CALG_RSA_KEYX:CALG_AES_128:CALG_DH_EPHEM"
  https://github.com The specific names come from wincrypt.h

tests/libtest: Add lib1521 to nodist_SOURCES
  
  Since 467da3af0, lib1521.c is generated instead of checked in. According

  as well. However, it is still present when running make dist. To remove
  it, add it to nodist_lib1521_SOURCES. This also means there is no need
  for the manually added dist-rule in the Makefile.
  
  Also update CMakelists.txt to handle the fact that we now may have
  nodist_SOURCES.

system.h: add support for IBM xlc C compiler
  
  Added a section to system.h guarded with __xlc__ for the IBM xml C
  compiler. Before this change the section titled 'generic "safe guess" on

  CURL_TYPEOF_CURL_SOCKLEN_T, and for 64-bit also CURL_TYPEOF_CURL_OFF_T
  was wrong.

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.

URL: fix ASCII dependency in strcpy_url and strlen_url
  
  Commit 3c630f9b0af097663a64e5c875c580aa9808a92b partially reverted the
  changes from commit dd7521bcc1b7a6fcb53c31f9bd1192fcc884bd56 because of
  the problem that strcpy_url() was modified unilaterally without also
  modifying strlen_url(). As a consequence strcpy_url() was again
  depending on ASCII encoding.
  
  This change fixes strlen_url() and strcpy_url() in parallel to use a
  common host-encoding independent criterion for deciding whether an URL

schannel: add support for CURLOPT_CAINFO
  
  - Move verify_certificate functionality in schannel.c into a new
    file called schannel_verify.c. Additionally, some structure defintions
    from schannel.c have been moved to schannel.h to allow them to be
    used in schannel_verify.c.
  
  - Make verify_certificate functionality for Schannel available on
    all versions of Windows instead of just Windows CE. verify_certificate
    will be invoked on Windows CE or when the user specifies
    CURLOPT_CAINFO and CURLOPT_SSL_VERIFYPEER.
  
  - In verify_certificate, create a custom certificate chain engine that
    exclusively trusts the certificate store backed by the CURLOPT_CAINFO
    file.
  
  - doc updates of --cacert/CAINFO support for schannel
  
  - Use CERT_NAME_SEARCH_ALL_NAMES_FLAG when invoking CertGetNameString
    when available. This implements a TODO in schannel.c to improve
    handling of multiple SANs in a certificate. In particular, all SANs
    will now be searched instead of just the first name.
  
  - Update tool_operate.c to not search for the curl-ca-bundle.crt file
    when using Schannel to maintain backward compatibility. Previously,
    any curl-ca-bundle.crt file found in that search would have been
    ignored by Schannel. But, with CAINFO support, the file found by
    that search would have been used as the certificate store and
    could cause issues for any users that have curl-ca-bundle.crt in
    the search path.
  
  - Update url.c to not set the build time CURL_CA_BUNDLE if the selected
    SSL backend is Schannel. We allow setting CA location for schannel
    only when explicitly specified by the user via CURLOPT_CAINFO /
    --cacert.
  
  - Add new test cases 3000 and 3001. These test cases check that the first
    and last SAN, respectively, matches the connection hostname. New test
    certificates have been added for these cases. For 3000, the certificate
    prefix is Server-localhost-firstSAN and for 3001, the certificate
    prefix is Server-localhost-secondSAN.
  
  - Remove TODO 15.2 (Add support for custom server certificate
    validation), this commit addresses it.

  Due to the check in Makefile.vc and MakefileBuild.vc, no make call can
  be invoked unless a build-type was specified. However, a clean target
  only existed when a build type was specified. As a result, the clean
  target was unreachable. Made clean target unconditional.

FTP: allow PASV on IPv6 connections when a proxy is being used
  
  In the situation of a client connecting to an FTP server using an IPv6
  tunnel proxy, the connection info will indicate that the connection is
  IPv6. However, because the server behing the proxy is IPv4, it is
  permissable to attempt PSV mode. In the case of the FTP server being
  IPv4 only, EPSV will always fail, and with the current logic curl will
  be unable to connect to the server, as the IPv6 fwdproxy causes curl to
  think that EPSV is impossible.
  
  Closes #2432

file: restore old behavior for file:////foo/bar URLs
  
  curl 7.57.0 and up interpret this according to Appendix E.3.2 of RFC
  8089 but then returns an error saying this is unimplemented. This is
  actually a regression in behavior on both Windows and Unix.
  
  Before curl 7.57.0 this URL was treated as a path of "//foo/bar" and
  then passed to the relevant OS API. This means that the behavior of this
  case is actually OS dependent.
  
  The Unix path resolution rules say that the OS must handle swallowing
  the extra "/" and so this path is the same as "/foo/bar"
  
  The Windows path resolution rules say that this is a UNC path and
  automatically handles the SMB access for the program. So curl on Windows
  was already doing Appendix E.3.2 without any special code in curl.
  
  Regression

Revert "openssl: Don't add verify locations when verifypeer==0"
  
  This reverts commit dc85437736e1fc90e689bb1f6c51c8f1aa9430eb.
  
  libcurl (with the OpenSSL backend) performs server certificate verification
  even if verifypeer == 0 and the verification result is available using
  CURLINFO_SSL_VERIFYRESULT. The commit that is being reverted caused the
  CURLINFO_SSL_VERIFYRESULT to not have useful information for the
  verifypeer == 0 use case (it would always have
  X509_V_ERR_UNABLE_TO_GET_ISSUER_CERT_LOCALLY).

- multi: improved pending transfers handling => improved performance
  
  When a transfer is requested to get done and it is put in the pending
  queue when limited by number of connections, total or per-host, libcurl
  would previously very aggressively retry *ALL* pending transfers to get
  them transferring. That was very time consuming.
  
  By reducing the aggressiveness in how pending are being retried, we
  waste MUCH less time on putting transfers back into pending again.
  
  Some test cases got a factor 30(!) speed improvement with this change.
  
  Reported-by: Cyril B

- pause: when changing pause state, update socket state
  
  Especially unpausing a transfer might have to move the socket back to the

  multi_socket API.

SSH: Fix state machine for ssh-agent authentication
  
  In case an identity didn't match[0], the state machine would fail in
  state SSH_AUTH_AGENT instead of progressing to the next identity in
  ssh-agent. As a result, ssh-agent authentication only worked if the
  identity required happened to be the first added to ssh-agent.
  
  This was introduced as part of commit c4eb10e2f06fbd6cc904f1d78e4, which
  stated that the "else" statement was required to prevent getting stuck
  in state SSH_AUTH_AGENT. Given the state machine's logic and libssh2's
  interface I couldn't see how this could happen or reproduce it and I
  also couldn't find a more detailed description of the problem which
  would explain a test case to reproduce the problem this was supposed to

- mime: clone mime tree upon easy handle duplication.
  
  A mime tree attached to an easy handle using CURLOPT_MIMEPOST is
  strongly bound to the handle: there is a pointer to the easy handle in
  each item of the mime tree and following the parent pointer list
  of mime items ends in a dummy part stored within the handle.
  
  Because of this binding, a mime tree cannot be shared between different
  easy handles, thus it needs to be cloned upon easy handle duplication.
  
  There is no way for the caller to get the duplicated mime tree
  handle: it is then set to be automatically destroyed upon freeing the
  new easy handle.
  
  New test 654 checks proper mime structure duplication/release.
  
  Add a warning note in curl_mime_data_cb() documentation about sharing
  user data between duplicated handles.

http2: fix incorrect trailer buffer size
  
  Prior to this change the stored byte count of each trailer was
  miscalculated and 1 less than required. It appears any trailer
  after the first that was passed to Curl_client_write would be truncated
  or corrupted as well as the size. Potentially the size of some
  subsequent trailer could be erroneously extracted from the contents of
  that trailer, and since that size is used by client write an
  out-of-bounds read could occur and cause a crash or be otherwise

  Prior to this change SSLKEYLOGFILE used line buffering on WIN32 just

  actually support line buffering (_IOLBF) and will use full buffering
  (_IOFBF) instead. We can't use full buffering because multiple processes
  may be writing to the file and that could lead to corruption, and since
  full buffering is the only buffering available this commit disables
  buffering for Windows SSLKEYLOGFILE entirely (_IONBF).

  This change is for posterity. Currently there doesn't seem to be a code

  pending data and the connssl handle doesn't yet exist [1].
  
  [1]: Recall that an https proxy connection starts out in connssl but if
  the destination is also https then the proxy SSL backend data is moved
  from connssl to proxyssl, which means connssl handle is temporarily
  empty until an SSL handle for the destination can be created.

lib: don't export all symbols, just everything curl_*
  
  Absent any 'symbol map' or script to limit what gets exported, static
  linking of libraries previously resulted in a libcurl with curl's and
  those other symbols being (re-)exported.
  
  This did not happen if 'versioned symbols' were enabled (which is not
  the default) because then a version script is employed.
  
  This limits exports to everything starting in 'curl_*'., which is
  what "libcurl.vers" exports.
  
  This avoids strange side-effects such as with mixing methods
  from system libraries and those erroneously offered by libcurl.

SSL: Avoid magic allocation of SSL backend specific data
  
  Originally, my idea was to allocate the two structures (or more
  precisely, the connectdata structure and the four SSL backend-specific
  strucutres required for ssl[0..1] and proxy_ssl[0..1]) in one go, so
  that they all could be free()d together.
  
  However, getting the alignment right is tricky. Too tricky.
  
  So let's just bite the bullet and allocate the SSL backend-specific
  data separately.
  
  As a consequence, we now have to be very careful to release the memory
  allocated for the SSL backend-specific data whenever we release any
  connectdata.

url: fix alignment of ssl_backend_data struct
  
  - Align the array of ssl_backend_data on a max 32 byte boundary.
  
  8 is likely to be ok but I went with 32 for posterity should one of
  the ssl_backend_data structs change to contain a larger sized variable
  in the future.
  
  Prior to this change (since dev 70f1db3, release 7.56) the connectdata
  structure was undersized by 4 bytes in 32-bit builds with ssl enabled
  because long long * was mistakenly used for alignment instead of
  long long, with the intention being an 8 byte boundary. Also long long
  may not be an available type.
  
  The undersized connectdata could lead to oob read/write past the end in
  what was expected to be the last 4 bytes of the connection's secondary
  socket https proxy ssl_backend_data struct (the secondary socket in a
  connection is used by ftp, others?).

  The new API added in Linux 4.11 only requires setting a socket option
  before connecting, without the whole sento() machinery.
  
  Notably, this makes it possible to use TFO with SSL connections on Linux
  as well, without the need to mess around with OpenSSL (or whatever other
  SSL library) internals.

--interface: add support for Linux VRF
  
  The --interface command (CURLOPT_INTERFACE option) already uses
  SO_BINDTODEVICE on Linux, but it tries to parse it as an interface or IP
  address first, which fails in case the user passes a VRF.
  
  Try to use the socket option immediately and parse it as a fallback
  instead.  Update the documentation to mention this feature, and that it
  requires the binary to be ran by root or with CAP_NET_RAW capabilities
  for this to work.

- content_encoding: fix inflate_stream for no bytes available
  
  - Don't call zlib's inflate() when avail_in stream bytes is 0.
  
  This is a follow up to the parent commit 19e66e5. Prior to that change
  libcurl's inflate_stream could call zlib's inflate even when no bytes
  were available, causing inflate to return Z_BUF_ERROR, and then
  inflate_stream would treat that as a hard error and return
  CURLE_BAD_CONTENT_ENCODING.
  
  According to the zlib FAQ, Z_BUF_ERROR is not fatal.
  
  This bug would happen randomly since packet sizes are arbitrary. A test
  of 10,000 transfers had 55 fail (ie 0.55%).

  Some tests are updated to accomodate with the now configuration dependent
  parameters of the Accept-Encoding header.

- HTTP: support multiple Content-Encodings
  
  This is implemented as an output streaming stack of unencoders, the last
  calling the client write procedure.

- transfer: Fix chunked-encoding upload bug
  
  - When uploading via chunked-encoding don't compare file size to bytes
    sent to determine whether the upload has finished.
  
  Chunked-encoding adds its own overhead which why the bytes sent is not
  equal to the file size. Prior to this change if a file was uploaded in
  chunked-encoding and its size was known it was possible that the upload
  could end prematurely without sending the final few chunks. That would
  result in a server hang waiting for the remaining data, likely followed
  by a disconnect.
  
  The scope of this bug is limited to some arbitrary file sizes which have
  not been determined. One size that triggers the bug is 475020.

url: Update current connection SSL verify params in setopt
  
  Now VERIFYHOST, VERIFYPEER and VERIFYSTATUS options change during active
  connection updates the current connection's (i.e.'connectdata'
  structure) appropriate ssl_config (and ssl_proxy_config) structures

openssl: don't use old BORINGSSL_YYYYMM macros
  
  Those were temporary things we'd add and remove for our own convenience

  have since been removed. These days we have a running

  The source code is now prepared to handle the case when both
  Win32 Crypto and OpenSSL/NSS crypto backends are enabled
  at the same time, making it now possible to enable `USE_WIN32_CRYPTO`
  whenever the targeted Windows version supports it. Since this
  matches the minimum Windows version supported by curl
  (Windows 2000), enable it unconditionally for the Win32 platform.
  
  This in turn enables SMB (and SMBS) protocol support whenever
  Win32 Crypto is available, regardless of what other crypto backends
  are enabled.

- test650: Use variable replacement to set the host address and port
  
  Otherwise, the test fails when the -b test option is used to set a
  different test port range.

- Set and use more necessary options when some protocols are disabled
  
  When curl and libcurl are built with some protocols disabled, they stop
  setting and receiving some options that don't make sense with those
  protocols.  In particular, when HTTP is disabled many options aren't set
  that are used only by HTTP.  However, some options that appear to be
  HTTP-only are actually used by other protocols as well (some despite
  having HTTP in the name) and should be set, but weren't. This change now
  causes some of these options to be set and used for more (or for all)
  protocols. In particular, this fixes tests 646 through 649 in an
  HTTP-disabled build, which use the MIME API in the mail protocols.

- metalink: fix NSS issue in MultiSSL builds
  
  In MultiSSL mode (i.e. when more than one SSL backend is compiled
  in), we cannot use the compile time flag `USE_NSS` as indicator that
  the NSS backend is in use. As far as Metalink is concerned, the SSL
  backend is only used for MD5, SHA-1 and SHA-256 calculations,
  therefore one of the available SSL backends is selected at compile
  time, in a strict order of preference.
  
  Let's introduce a new `HAVE_NSS_CONTEXT` constant that can be used
  to determine whether the SSL backend used for Metalink is the NSS
  backend, and use that to guard the code that wants to de-initialize
  the NSS-specific data structure.
  
  Ref: https://github.com/curl/curl/pull/1848

- ntlm: use strict order for SSL backend #if branches
  
  With the recently introduced MultiSSL support multiple SSL backends
  can be compiled into cURL That means that now the order of the SSL
  
  One option would be to use the same SSL backend as was configured
  via `curl_global_sslset()`, however, NTLMv2 support would appear
  to be available only with some SSL backends. For example, when
  eb88d778e (ntlm: Use Windows Crypt API, 2014-12-02) introduced
  support for NTLMv1 using Windows' Crypt API, it specifically did
  *not* introduce NTLMv2 support using Crypt API at the same time.
  
  So let's select one specific SSL backend for NTLM support when
  compiled with multiple SSL backends, using a priority order such
  that we support NTLMv2 even if only one compiled-in SSL backend can
  be used for that.
