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.
