POE::Component::SmokeBox::Uploads::Rsync - Obtain uploaded CPAN modules via rsync
This document describes v1.000 of POE::Component::SmokeBox::Uploads::Rsync - released March 31, 2011 as part of POE-Component-SmokeBox-Uploads-Rsync.
#!/usr/bin/perl use strict; use warnings; use POE; use POE::Component::SmokeBox::Uploads::Rsync; # Create our session to receive events from rsync POE::Session->create( package_states => [ 'main' => [qw(_start upload)], ], ); sub _start { # Tell the poco to start it's stuff! POE::Component::SmokeBox::Uploads::Rsync->spawn( # thanks to DAGOLDEN for allowing us to use his mirror! 'rsync_src' => 'cpan.dagolden.com::CPAN', ) or die "Unable to spawn the poco-rsync!"; return; } sub upload { print $_[ARG0], "\n"; return; } POE::Kernel->run;
POE::Component::SmokeBox::Uploads::Rsync is a POE component that alerts newly uploaded CPAN distributions. It obtains this information by running rsync against a CPAN mirror. This effectively keeps your local CPAN mirror up-to-date too! This is only for the CPAN/authors/id directory, to make it easier on the rsync process. If you want to keep your entire mirror up-to-date, please use your normal ( crontabbed? ) rsync script and tell it to exclude the authors/id directory to prevent missed uploads.
CPAN/authors/id
authors/id
Really, all you have to do is load the module and call it's spawn() method:
use POE::Component::SmokeBox::Uploads::Rsync; POE::Component::SmokeBox::Uploads::Rsync->spawn( ... );
This method will return failure on errors or return success. Normally you just need to set the rsync server. ( rsync_src )
This constructor accepts either a hashref or a hash, valid options are:
This sets the alias of the session.
The default is: SmokeBox-Rsync
This sets the rsync source ( the server you will be mirroring from ) and it is a mandatory parameter. For a list of valid rsync mirrors, please consult the http://www.cpan.org/SITES.html mirror list.
The default is: undefined
This component will automatically append '/authors/id' to the src, please don't add it yourself.
This sets the local rsync destination ( where your local CPAN mirror resides )
The default is: $ENV{HOME}/CPAN
This component will automatically append '/authors' to the dst, please don't add it yourself.
This sets the rsync options. Normally you do not need to touch this, but if you do - please be aware that your options clobbers the default values! Please look at the File::Rsync manpage for the options. Again, touch this if you know what you are doing!
The default is:
{ archive => 1, compress => 1, omit-dir-times => 1, itemize-changes => 1, timeout => 10 * 60, # 10min contimeout => 2 * 60, # 2min literal => [ qw( --no-motd ) ], }
NOTE: The usage of "omit-dir-times/itemize-changes/contimeout" means you need a rsync newer than v3.0.0!
This sets the seconds between rsync mirror executions. Please don't set it to a low value unless you have permission from the mirror admin!
The default is: 3600 ( 1 hour )
This sets the event which will receive notification about uploaded dists. It will receive one argument in ARG0, which is a single string. An example is:
V/VP/VPIT/CPANPLUS-Dist-Gentoo-0.07.tar.gz
The default is: upload
This sets the session which will receive the notification event. You can either use a POE session id, alias, or reference. You can just spawn the component inside another session and it will automatically receive the notifications.
The default is: undef ( caller session )
This sets an additional event when the rsync process is done executing. It will receive a hashref in ARG0 which details some information. An example is:
{ 'status' => 1, # boolean value whether the rsync run was successful or not 'exit' => 0, # exit code of the rsync process, useful to look up rsync errors ( already bit-shifted! ) 'exit_str' => 'Success', # stringified exit code of the rsync process 'starttime' => 1260432932, # self-explanatory 'stoptime' => 1260432965, # self-explanatory 'dists' => 7, # number of new distributions uploaded to CPAN }
NOTE: In my testing sometimes rsync throws an exit code of 23 ( Partial transfer due to error ) or 24 ( Partial transfer due to vanished source files ), this module automatically treats them as "success" and sets the exit code to 0. This is caused by the intricacies of rsync trying to mirror some forbidden files and deletions on the host. See https://bugzilla.samba.org/show_bug.cgi?id=3653 for more info.
The default is: undef ( not enabled )
There is only one command you can use, as this is a very simple module.
Tells this module to shut down the underlying rsync session and terminate itself.
$_[KERNEL]->post( 'SmokeBox-Rsync', 'shutdown' );
You can enable debugging mode by doing this:
sub POE::Component::SmokeBox::Uploads::Rsync::DEBUG () { 1 } use POE::Component::SmokeBox::Uploads::Rsync;
