#pod     $http = HTTP::Tiny->new( %attributes );
#pod
#pod This constructor returns a new HTTP::Tiny object.  Valid attributes include:
#pod
#pod =for :list
#pod * C<agent> — A user-agent string (defaults to 'HTTP-Tiny/$VERSION'). If
#pod   C<agent> — ends in a space character, the default user-agent string is
#pod   appended.
#pod * C<cookie_jar> — An instance of L<HTTP::CookieJar> — or equivalent class
#pod   that supports the C<add> and C<cookie_header> methods
#pod * C<default_headers> — A hashref of default headers to apply to requests
#pod * C<local_address> — The local IP address to bind to
#pod * C<keep_alive> — Whether to reuse the last connection (if for the same
#pod   scheme, host and port) (defaults to 1)
#pod * C<max_redirect> — Maximum number of redirects allowed (defaults to 5)
#pod * C<max_size> — Maximum response size in bytes (only when not using a data
#pod   callback).  If defined, responses larger than this will return an
#pod   exception.
#pod * C<http_proxy> — URL of a proxy server to use for HTTP connections
#pod   (default is C<$ENV{http_proxy}> — if set)
#pod * C<https_proxy> — URL of a proxy server to use for HTTPS connections
#pod   (default is C<$ENV{https_proxy}> — if set)
#pod * C<proxy> — URL of a generic proxy server for both HTTP and HTTPS
#pod   connections (default is C<$ENV{all_proxy}> — if set)
#pod * C<no_proxy> — List of domain suffixes that should not be proxied.  Must
#pod   be a comma-separated string or an array reference. (default is
#pod   C<$ENV{no_proxy}> —)
#pod * C<timeout> — Request timeout in seconds (default is 60) If a socket open,
#pod   read or write takes longer than the timeout, an exception is thrown.
#pod * C<verify_SSL> — A boolean that indicates whether to validate the SSL
#pod   certificate of an C<https> — connection (default is false)
#pod * C<SSL_options> — A hashref of C<SSL_*> — options to pass through to
#pod   L<IO::Socket::SSL>
#pod
#pod Passing an explicit C<undef> for C<proxy>, C<http_proxy> or C<https_proxy> will
#pod prevent getting the corresponding proxies from the environment.
#pod
#pod Exceptions from C<max_size>, C<timeout> or other errors will result in a
#pod pseudo-HTTP status code of 599 and a reason of "Internal Exception". The
#pod content field in the response will contain the text of the exception.
#pod
#pod The C<keep_alive> parameter enables a persistent connection, but only to a
#pod single destination scheme, host and port.  Also, if any connection-relevant
#pod attributes are modified, or if the process ID or thread ID change, the
#pod persistent connection will be dropped.  If you want persistent connections
#pod across multiple destinations, use multiple HTTP::Tiny objects.
#pod
#pod See L</SSL SUPPORT> for more on the C<verify_SSL> and C<SSL_options> attributes.

#pod
#pod B<NOTE>: Method names are B<case-sensitive> per the HTTP/1.1 specification.
#pod Don't use C<get> when you really want C<GET>.  See L<LIMITATIONS> for
#pod how this applies to redirection.
#pod
#pod If the URL includes a "user:password" stanza, they will be used for Basic-style
#pod authorization headers.  (Authorization headers will not be included in a
#pod redirected request.) For example:
#pod
#pod     $http->request('GET', 'http://Aladdin:open sesame@example.com/');
#pod
#pod If the "user:password" stanza contains reserved characters, they must
#pod be percent-escaped:
#pod
#pod     $http->request('GET', 'http://john%40example.com:password@example.com/');
#pod
#pod A hashref of options may be appended to modify the request.
#pod
#pod Valid options are:
#pod
#pod =for :list
#pod * C<headers> —
#pod     A hashref containing headers to include with the request.  If the value for
#pod     a header is an array reference, the header will be output multiple times with
#pod     each value in the array.  These headers over-write any default headers.
#pod * C<content> —
#pod     A scalar to include as the body of the request OR a code reference
#pod     that will be called iteratively to produce the body of the request
#pod * C<trailer_callback> —
#pod     A code reference that will be called if it exists to provide a hashref
#pod     of trailing headers (only used with chunked transfer-encoding)
#pod * C<data_callback> —
#pod     A code reference that will be called for each chunks of the response
#pod     body received.
#pod * C<peer> —
#pod     Override host resolution and force all connections to go only to a
#pod     specific peer address, regardless of the URL of the request.  This will
#pod     include any redirections!  This options should be used with extreme
#pod     caution (e.g. debugging or very special circumstances). It can be given as
#pod     either a scalar or a code reference that will receive the hostname and
#pod     whose response will be taken as the address.
#pod
#pod The C<Host> header is generated from the URL in accordance with RFC 2616.  It
#pod is a fatal error to specify C<Host> in the C<headers> option.  Other headers
#pod may be ignored or overwritten if necessary for transport compliance.
#pod
#pod If the C<content> option is a code reference, it will be called iteratively
#pod to provide the content body of the request.  It should return the empty
#pod string or undef when the iterator is exhausted.
#pod
#pod If the C<content> option is the empty string, no C<content-type> or
#pod C<content-length> headers will be generated.
#pod
#pod If the C<data_callback> option is provided, it will be called iteratively until
#pod the entire response body is received.  The first argument will be a string
#pod containing a chunk of the response body, the second argument will be the
#pod in-progress response hash reference, as described below.  (This allows
#pod customizing the action of the callback based on the C<status> or C<headers>
#pod received prior to the content body.)
#pod
#pod The C<request> method returns a hashref containing the response.  The hashref
#pod will have the following keys:
#pod
#pod =for :list
#pod * C<success> —
#pod     Boolean indicating whether the operation returned a 2XX status code
#pod * C<url> —
#pod     URL that provided the response. This is the URL of the request unless
#pod     there were redirections, in which case it is the last URL queried
#pod     in a redirection chain
#pod * C<status> —
#pod     The HTTP status code of the response
#pod * C<reason> —
#pod     The response phrase returned by the server
#pod * C<content> —
#pod     The body of the response.  If the response does not have any content
#pod     or if a data callback is provided to consume the response body,
#pod     this will be the empty string
#pod * C<headers> —
#pod     A hashref of header fields.  All header field names will be normalized
#pod     to be lower case. If a header is repeated, the value will be an arrayref;
#pod     it will otherwise be a scalar string containing the value
#pod * C<protocol> -
#pod     If this field exists, it is the protocol of the response
#pod     such as HTTP/1.0 or HTTP/1.1
#pod * C<redirects>
#pod     If this field exists, it is an arrayref of response hash references from
#pod     redirects in the same order that redirections occurred.  If it does
#pod     not exist, then no redirections occurred.
#pod
#pod On an exception during the execution of the request, the C<status> field will
#pod contain 599, and the C<content> field will contain the text of the exception.

=head1 NAME

updatenow - updates /usr/local/cpanel from update servers

=head1 USAGE

    # Called from upcp like this:
    # --force tells updatenow to sync even if the version has not changed (similar to --sync). This setting will also bypass cron detection.
    updatenow --upcp

    # upcp will call this script like this if upcp is called with --force
    updatenow --upcp --force

    # If files which this script manages somehow get deleted, this will re-sync them but not upgrade.
    # This is used by other cpanel scripts as a safety measure.
    updatenow.static --sync

    # Used by cpanel installer prior to vps optimization
    updatenow --no-check-perl

=head1 DESCRIPTION

NOTE: Under most circumstances, you should never call this script directly. B</usr/local/cpanel/scripts/upcp>, called with an optional [--force]
should be all you need. --sync is only intended to be called by other cpanel scripts when it appears that cpanel managed files
have been deleted.

The normal usage of this script is to update cpanel to the latest version of your TIER I<(see /etc/cpupdate.conf)>.
By default, no update is done by default if you are already on that version. The UPDATES setting in cpupdate.conf
is also honored when the environment variable CPANEL_IS_CRON is set (usually from upcp).

If an HTTPUPDATE= setting is present in /etc/cpsources.conf with a hostname, this will be the preferred source to sync from.
