# Plugin SyncMercurial by Benjamin Jorand 

The SyncMercurial plugin allows the direct creation and synchronisation of
mercurial repositories with the InDefero database. The repositories will be
published by hgwebdir.cgi using HTTP. It also handles private repositories.

SyncMercurial is adapted from SyncSvn by Baptiste Michaud.

## Apache configuration

The simple way to share Mercurial repositories is to publish them
using HTTP and `hgwebdir.cgi`.

It first requires a config file called hgweb.config in the same
directory where you put hgwebdir.cgi (for example,
`/home/indefero/scripts`):
    
    [collections]
    /home/indefero/repositories/mercurial/ = /home/indefero/repositories/mercurial/

Then configure a vhost this way :

    ScriptAliasMatch ^/hg(.*) /home/indefero/scripts/hgwebdir.cgi$1
    <Directory /home/indefero/scripts>
        Options +ExecCGI
        AuthName "Restricted"
        AuthType Basic
        AuthUserFile /home/indefero/auth/.htpasswd
        <Limit PUT POST>
            Require valid-user
        </Limit>
    </Directory>

Enable the authentification for private repositories :

    Include /home/indefero/scripts/private_indefero.conf

## InDefero configuration

First, you need to install the File_Passwd PEAR package:

    $ sudo pear install File_Passwd

Then, based on the paths provided in the Apache configuration, you
need to put the following lines in your configuration file:

    $cfg['idf_plugin_syncmercurial_passwd_file'] = '/home/indefero/auth/.htpasswd';
    $cfg['idf_plugin_syncmercurial_path'] = '/home/indefero/repositories/mercurial';
    $cfg['idf_plugin_syncmercurial_private_include'] = '/home/indefero/scripts/private_indefero.conf';
    $cfg['idf_plugin_syncmercurial_private_notify'] = '/home/indefero/tmp/notify.tmp';
    $cfg['idf_plugin_syncmercurial_private_url'] = '/hg/%s';

You also need to provide the base definition of the hgrc file. For example:

    $cfg['idf_plugin_syncmercurial_hgrc'] = array(
               'web' => array('push_ssl' => 'false',
                              'allow_push' => '',
                              'description' => '',
                              'allow_archive' => 'bz2, zip, gz',
                              'style' => 'gitweb',
                              'contact' => ''),
               'hooks' => array(),
               'extensions' => array(),
                                                  );

If you are note using Apache but Nginx, you may need to create the
passwords as plain text passwords (see ticket 391). You can configure
the password storage with the format you want. The default is `sha`
you can set it to `plain` for nginx.

    $cfg['idf_plugin_syncmercurial_passwd_mode'] = 'sha';

See the [`FILE_PASSWD_*` constants](http://euk1.php.net/package/File_Passwd/docs/latest/File_Passwd/_File_Passwd-1.1.7---Passwd.php.html) for more choices.

## Cron configuration

As InDefero modifies the private_indefero.conf, apache needs to be reloaded.
Each time this file is modified, a temporary file is created. 

    */5 * * * * /bin/sh /home/indefero/src/scripts/SyncMercurial.sh

Edit this script and add correct values to `private_notify` and `reload_cmd`.

## Hook configuratin

To get notifications sent directly when pushing in your repositories,
you need to add the following in your `.hgrc` file. The script will be
called onec per push and will automatically send the notifications and
sync the timeline.

    [hooks]
    changegroup = /home/indefero/src/scripts/hgchangegroup.php
