NAME

       Mirmon - OO interface for mirmon objects

SYNOPSIS

         use Mirmon ;

         $m = Mirmon -> new ( [ $path-to-config ] )

         $conf  = $m -> conf  ; # a Mirmon::Conf object
         $state = $m -> state ; # the mirmon state

         for my $url ( keys %$state )
           { $mirror = $state -> { $url } ; # a Mirmon::Mirror object
             $mail = $mirror -> mail ;      # contact address
             $mirror -> age ( time ) ;      # set mirror age
           }

       Many class and object methods can be used to get or set attributes :

         $object -> attribute           # get an atttibute
         $object -> attribute ( $attr ) # set an atttibute

Mirmon class methods

       new ( [$path] )
           Create a Mirmon object from a config file found in $path, or (by default) in the
           default list of possible config files.  Related objects (config, state) are created
           and initialised.

       verbosity
           Mirmon always reports errors. Normally it only reports changes (inserts/deletes) found
           in the mirror_list ; in quiet mode, it doesn't. In verbose mode, it reports progress:
           the startup and finishing of probes.

             Mirmon::verbose ( [ $bool ] ) # get/set verbose
             Mirmon::quiet   ( [ $bool ] ) # get/set quiet
             Mirmon::debug   ( [ $bool ] ) # get/set debug

Mirmon object methods

       conf
           Returns Mirmon's Mirmon::Conf object.

       state
           Returns a hashref "{ url => mirror, ... }", where url is as specified in the mirror
           list and mirror is a Mirmon::Mirror object.

       regions
           Returns a hashref "{ country_code => country_name, ... }".

       config_list
           Returns the list of default locations for config files.

       get_dates ( $get [, $URL] )
           Probes all mirrors if $get is "all" ; or a subset if $get is "update" ; or only $URL
           if $get is "url".

Mirmon::Conf object methods

       A Mirmon::Conf object represents a mirmon conguration.  It is normaly created by
       Mirmon::new().  A specified (or default) config file is read and interpreted.

       attribute methods
           For every config file entry, there is an attribute method : web_page, state,
           countries, mirror_list, probe, project_name, project_url, icons, project_logo,
           timeout, max_probes, min_poll, max_poll, min_sync, max_sync, list_style, put_histo,
           randomize, add_slash.

       root
           Returns the file name of (the root of) the configuration file(s).

       site_url
           Returns a hashref "{ site => url, ... }", as specified in the mirmon config file.

Mirmon::Mirror object methods

       A Mirmon::Mirror object represents the last known state of a mirror.  It is normaly
       created by Mirmon::new() from the state file, as specified in the mirmon config file.
       Mirmon::Mirror objects can be used to probe mirrors.

       attribute methods

       url The url as given in the mirror list.

       age The mirror's timestamp found by the last successful probe, or 'undef' if no probe was
           ever successful.

       last_status
           The status of the last probe, or 'undef' if the mirror was never probed.

       last_ok_probe
           The timestamp of the last successful probe or 'undef' if the mirror was never
           successfully probed.

       probe_history
           The probe history is a list of 's' (for success) and 'f' (for failure) characters
           indicating the result of the probe. New results are appended whenever the mirror is
           probed.

       state_history
           The state history consists of a timestamp, a '-' char, and a list of chars indicating
           a past status: 's' (fresh), 'b' (oldish), 'f' (old), 'z' (bad) or 'x' (skip).  The
           timestamp indicates when the state history was last updated.  The current status of
           the mirror is determined by the mirror's age and a few configuration parameters
           (min_sync, max_sync, max_poll).  The state history is updated when the mirror is
           probed.  If the last update of the history was less than 24 hours ago, the last status
           is replaced by the current status.  If the last update of the history was more than 24
           hours ago, the current status is appended to the history.  One or more 'skip's are
           inserted, if the timestamp is two or more days old (when mirmon hasn't run for more
           than two days).

       last_probe
           The timestamp of the last probe, or 'undef' if the mirror was never probed.

       object methods

       mirmon
           Returns the parent Mirmon object.

       state_history_time
           Returns the time part of the state_history attribute.

       state_history_hist
           Returns the history part of the state_history attribute.

       type, site, home
           For an url like ftp://www.some.org/path/to/home, the type is ftp, the site is
           www.some.org, and home is ftp://www.some.org/.

       age_in_days
           Returns the mirror's age (in fractional days), based on the mirror's timestamp as
           found by the last successful probe ; or based on the length of the state history if no
           probe was ever successful.  Returns 'undef' if the mirror was never probed.

       mail
           Returns the mirror's contact address as specified in the mirror list.

       region
           Returns the mirror's country code as specified in the mirror list.

       start_probe
           Start a probe for the mirror in non-blocking mode ; returns the associated
           (IO::Handle) file handle.  The caller must maintain an association between the handles
           and the mirror objects.

       finish_probe ( $handle )
           Sets the (IO::Handle) $handle to blocking IO ; reads a result from the handle, and
           updates the state of the mirror.
