=head1 NAME

dupload.conf - configuration file for dupload

=head1 DESCRIPTION

The configuration file is rather straight forward Perl code as it is
included by the B<dupload> script via C<do $config>.  I<The config file
is read as Perl code!>

Any B<dupload.conf> must begin with C<package config;> because C<config> is
the namespace expected by B<dupload>.

For examples of the configuration please refer to the global configuration
file F</etc/dupload.conf>.

It contains associative arrays, each indexed by the nickname (see B<--to>
option of B<dupload>), for the following items:

=over 4

=item B<fqdn> [required]

The fully qualified domain name (FQDN) of the nickname.

For the B<copy> method, this option is ignored and the local
FQDN will be used instead.

=item B<method> [optional]

The transfer method. The available methods are: B<ftp>
(which is the default), B<scp>, B<scpb>, B<rsync> (over SSH) and
B<copy> (local filesystem).

If you are using an upload queue, use B<ftp> because it is fast.
If you are using an authenticated host, B<always> use B<scp> or B<rsync>
via SSH, because B<ftp> transmits the password in clear text.

For B<scp> and B<rsync> to work properly, you have to setup the remote
and local host to establish a ssh/slogin connection using F<.shosts/.rhosts>
or the files in F<~/.ssh/>. If you do not want or cannot do that,
you may find the B<scpb> more convenient since it uploads in batch,
reducing the number of password prompts.

The only major caveat of the B<rsync> and B<scpb> options is that the files are
processed in a batch mode, i.e. not separately, so in case of an error
B<dupload> will not be able to detect which part of the transfer failed, and
just delete the B<.upload> file completely.

=item B<login> [optional]

The account name used to log into the remote host.
For B<ftp> the default is B<anonymous>, which should work with firewall
logins too.
For B<scp>, B<scpb> and B<rsync> the default is delegated to SSH and its
own configuration.

=item B<password> [optional]

The FTP password for anonymous logins.

=item B<filemode> [optional]

The destination files mode, in octal. If the value is B<undef>, the mode
will not be modified. The default is B<0644>.

=item B<incoming> [required]

Incoming directory, the directory we try to upload to.

=item B<queuedir> [optional]

The directory we move the uploaded files to (after successful upload to
I<incoming>. Usually necessary only with some special upload queues.

=item B<distwhitelist> [optional]

The regex of the distributions allowed for this host. This check is done
against the B<Distribution> field in the F<.changes> file.

=item B<distblacklist> [optional]

The regex of the distributions disallowed for this host. This check is done
against the B<Distribution> field in the F<.changes> file.

=item B<mailto> [optional]

Email address where the announcement about stable packages is sent.

=item B<mailtx> [optional]

Email address where the announcement about unstable and experimental
packages is sent.

=item B<cc> [optional]

Email address where to send a copy address of the announcement.

=item B<fullname> [optional]

Your full name, one that should appear in the announcement;

If you leave this setting empty, the default will depend on your mail
system. Usually the full name will be copied from the GCOS field in
F</etc/passwd>.

=item B<visibleuser> [optional]

Your username that should appear in the announcement. Defaults to
C<getlogin()>.

=item B<visiblename> [optional]

The host/domain name that appears as the part to the right of the B<@>
character in the I<from>-part of the announcement. Defaults to the value
your local MTA likes.

=item B<passive> [optional]

Set the passive mode for FTP transfers. Since B<dupload> uses L<Net::FTP>,
you can also use the environment variable B<FTP_PASSIVE>.

=item B<options> [optional]

String that will be added verbatim to the command line of any
B<scp> or B<rsync> calls done.

=item B<dinstall_runs> [optional]

Tells B<dupload> that the remote host runs dinstall (or equivalent)
so that B<dupload> will not send a duplicate announcement mail.
The default is 0 (false), set it to 1 to enable it.

=item B<archive> [optional]

If set to 0 (false), adds a B<X-No-Archive: yes> header in the announcement.
The default is 1 (true).

=back

The configuration files also contain the following global variables:

=over 4

=item B<default_host> [optional]

The default host to upload to. The default value of this variable is set
depending on the current vendor, but if there is no configuration for that
vendor it will be left unset.

=item B<no_parentheses_to_fullname> [optional]

Prevents B<dupload> to add parentheses around the full name when making
mail announcements. Default is 0 (false), set it to 1 to enable it.

=head1 HOOKS

Hooks are a powerful way to add actions which will be run before or
after a dupload (like the preinst and postinst script of B<dpkg>).

You have two sort of hooks: pre-upload and post-upload. Both are simple
shell commands (executed by C<sh -c> so you can use any shell tricks).
Pre-uploads are
always run (even in dry mode) and stop B<dupload> if they fail
(failure being measured by the hook's exit status). Post-uploads
are only run when you are not in dry mode and only if the uploading succeeded.

Both sorts of hooks are run for a given category: B<changes>, B<sourcepackage>,
B<package>, B<file> or B<deb>.

=over 4

=item changes

This hook is run once per F<changes> file (given as an argument to B<dupload>)
with the filename as its parameter.

=item sourcepackage

This hook is run once per F<changes> file
with the source package name and its version as its two parameters.

=item package

This hook is run once per binary package (a F<deb> file) with
the package name and its version as its two parameters.

=item file

This hook is run once per uploaded file, with the file name as its parameter.

=item deb

This hook is run once per binary package (a F<deb> file) with
the filename as its parameter.

=back

=head2 Syntax

Hooks are defined in two Perl hashes, C<%preupload> and C<%postupload>, each indexed
by category. In addition to the global hashes, each host entry has two fields
with the same names, for the host-specific hooks.

The shell command will be substituted first: C<%1> will be replace by the first
argument, etc.

=head2 Per-host or global hooks

A hook can be global (for all the hosts) or it can be for a specific host.
Host specific hooks override the global ones for each category.

=head2 Examples

This one runs B<lintian> before uploading. It is global and guarantee
that you will always upload lintian-clean packages (thanks to B<lintian>
return status).

     $preupload{'deb'} = 'lintian -v -i %1';

This one just display the name and versions of successfully uploaded packages.

     $postupload{'package'} = 'echo PACKAGE %1 %2 uploaded';

Unlike the two others, this one is specific to one host, master, and overrides
the default global hook in charge of checking the OpenPGP signatures:

     $cfg{master}{preupload}{'changes'} = "echo Uploading %1";


=head1 FILES

The configuration is searched as following:

	/etc/dupload.conf
	~/.dupload.conf

The latest entries override the former.

=head1 ENVIRONMENT

Those of L<Net::FTP> for the FTP method:

 FTP_FIREWALL
 FTP_PASSIVE
