);


//=========================================================================
// 2. WEB SITE LOCATION
//=========================================================================
// Now you need to tell Moodle where it is located. Specify the full
// web address to where moodle has been installed.  If your web site
// is accessible via multiple URLs then choose the most natural one
// that your students would use.  Do not include a trailing slash
//
// If you need both intranet and Internet access please read
// http://docs.moodle.org/en/masquerading

//=========================================================================
// 3. DATA FILES LOCATION
//=========================================================================
// Now you need a place where Moodle can save uploaded files.  This
// directory should be readable AND WRITEABLE by the web server user
// (usually 'nobody' or 'apache'), but it should not be accessible
// directly via the web.
//
// - On hosting systems you might need to make sure that your "group" has
//   no permissions at all, but that "others" have full permissions.
//
// - On Windows systems you might specify something like 'c:\moodledata'

$CFG->dataroot  = '/moodledata';


//=========================================================================
// 4. DATA FILES PERMISSIONS
//=========================================================================
// The following parameter sets the permissions of new directories
// created by Moodle within the data directory.  The format is in
// octal format (as used by the Unix utility chmod, for example).
// The default is usually OK, but you may want to change it to 0750
// if you are concerned about world-access to the files (you will need
// to make sure the web server process (eg Apache) can access the files.
// NOTE: the prefixed 0 is important, and don't use quotes.

$CFG->directorypermissions = 02777;


//=========================================================================
// 5. DIRECTORY LOCATION  (most people can just ignore this setting)
//=========================================================================
// A very few webhosts use /admin as a special URL for you to access a
// control panel or something.  Unfortunately this conflicts with the
// standard location for the Moodle admin pages.  You can work around this
// by renaming the admin directory in your installation, and putting that
// new name here.  eg "moodleadmin".  This should fix all admin links in Moodle.
// After any change you need to visit your new admin directory
// and purge all caches.

$CFG->admin = 'admin';


//=========================================================================
// 6. OTHER MISCELLANEOUS SETTINGS (ignore these for new installations)
//=========================================================================
//
// These are additional tweaks for which no GUI exists in Moodle yet.
//
// Starting in PHP 5.3 administrators should specify default timezone
// in PHP.ini, you can also specify it here if needed.
// See details at: http://php.net/manual/en/function.date-default-timezone-set.php
// List of time zones at: http://php.net/manual/en/timezones.php
//     date_default_timezone_set('Australia/Perth');
//
// Change the key pair lifetime for Moodle Networking
// The default is 28 days. You would only want to change this if the key
// was not getting regenerated for any reason. You would probably want
// make it much longer. Note that you'll need to delete and manually update
// any existing key.

// off non-Moodle standard characters in usernames.
//      $CFG->extendedusernamechars = true;
//
// Allow user passwords to be included in backup files. Very dangerous
// setting as far as it publishes password hashes that can be unencrypted
// if the backup file is publicy available. Use it only if you can guarantee
// that all your backup files remain only privacy available and are never
// shared out from your site/institution!
//      $CFG->includeuserpasswordsinbackup = true;
//
// Completely disable user creation when restoring a course, bypassing any
// permissions granted via roles and capabilities. Enabling this setting
// results in the restore process stopping when a user attempts to restore a
// course requiring users to be created.
//     $CFG->disableusercreationonrestore = true;
//
// Keep the temporary directories used by backup and restore without being
// deleted at the end of the process. Use it if you want to debug / view
// all the information stored there after the process has ended. Note that
// those directories may be deleted (after some ttl) both by cron and / or
// by new backup / restore invocations.
//     $CFG->keeptempdirectoriesonbackup = true;
//
// Modify the restore process in order to force the "user checks" to assume
// that the backup originated from a different site, so detection of matching
// users is performed with different (more "relaxed") rules. Note that this is
// only useful if the backup file has been created using Moodle < 1.9.4 and the
// site has been rebuilt from scratch using backup files (not the best way btw).
// If you obtain user conflicts on restore, rather than enabling this setting
// permanently, try restoring the backup on a different site, back it up again
// and then restore on the target server.
//    $CFG->forcedifferentsitecheckingusersonrestore = true;
//
// Force the backup system to continue to create backups in the legacy zip
// format instead of the new tgz format. Does not affect restore, which
// auto-detects the underlying file format.
//    $CFG->usezipbackups = true;

// Prevent stats processing and hide the GUI
//      $CFG->disablestatsprocessing = true;
//
// Setting this to true will enable admins to edit any post at any time
//      $CFG->admineditalways = true;
//
// These variables define DEFAULT block variables for new courses
// If this one is set it overrides all others and is the only one used.
//      $CFG->defaultblocks_override = 'participants,activity_modules,search_forums,course_list:news_items,calendar_upcoming,recent_activity';
//
// These variables define the specific settings for defined course formats.
// They override any settings defined in the formats own config file.

// These blocks are used when no other default setting is found.
//      $CFG->defaultblocks = 'participants,activity_modules,search_forums,course_list:news_items,calendar_upcoming,recent_activity';
//
// You can specify a different class to be created for the $PAGE global, and to
// compute which blocks appear on each page. However, I cannot think of any good
// reason why you would need to change that. It just felt wrong to hard-code the
// the class name. You are strongly advised not to use these to settings unless
// you are absolutely sure you know what you are doing.

// about students being served outdated versions of uploaded files.
//     $CFG->filelifetime = 60*60*6;
//
// Some web servers can offload the file serving from PHP process,

//     $CFG->xsendfile = 'X-LIGHTTPD-send-file'; // Lighttpd {@see http://redmine.lighttpd.net/projects/lighttpd/wiki/X-LIGHTTPD-send-file}
//     $CFG->xsendfile = 'X-Accel-Redirect';     // Nginx {@see http://wiki.nginx.org/XSendfile}

//         '/dataroot/' => $CFG->dataroot,
//         '/cachedir/' => '/var/www/moodle/cache',    // for custom $CFG->cachedir locations

//
// YUI caching may be sometimes improved by slasharguments:
//     $CFG->yuislasharguments = 1;
// Some servers may need a special rewrite rule to work around internal path length limitations:
// RewriteRule (^.*/theme/yui_combo\.php)(/.*) $1?file=$2

//
// You can force the browser session (not user's sessions) to restart after N seconds. This could
// be useful if you are using a cloud-based service with time restrictions in the browser side.
// Setting this value the browser session that Behat is using will be restarted. Set the time in
// seconds. Is not recommended to use this setting if you don't explicitly need it.
// Example:
//   $CFG->behat_restart_browser_after = 7200;     // Restarts the browser session after 2 hours
//
// All this page's extra Moodle settings are compared against a white list of allowed settings
// (the basic and behat_* ones) to avoid problems with production environments. This setting can be
// used to expand the default white list with an array of extra settings.
// Example:
//   $CFG->behat_extraallowedsettings = array('somecoresetting', ...);
//
// You should explicitly allow the usage of the deprecated behat steps, otherwise an exception will
// be thrown when using them. The setting is disabled by default.
// Example:
//   $CFG->behat_usedeprecated = true;
//
// If you are using a slow machine, it may help to increase the timeouts that Behat uses. The
// following example will increase timeouts by a factor of 3 (using 30 seconds instead of 10
// seconds, for instance).
// Example:
//   $CFG->behat_increasetimeout = 3;
//
// Including feature files from directories outside the dirroot is possible if required. The setting
// requires that the running user has executable permissions on all parent directories in the paths.
// Example:
//   $CFG->behat_additionalfeatures = array('/home/developer/code/wipfeatures');
//
// You can make behat save several dumps when a scenario fails. The dumps currently saved are:
// * a dump of the DOM in it's state at the time of failure; and
// * a screenshot (JavaScript is required for the screenshot functionality, so not all browsers support this option)
// Example:
//   $CFG->behat_faildump_path = '/my/path/to/save/failure/dumps';
//
// You can specify db, selenium wd_host etc. for behat parallel run by setting following variable.
// Example:
//   $CFG->behat_parallel_run = array (
//       array (
//           'dbtype' => 'mysqli',
//           'dblibrary' => 'native',
//           'dbhost' => 'localhost',
//           'dbname' => 'moodletest',
//           'dbuser' => 'moodle',
//           'dbpass' => 'moodle',
//           'behat_prefix' => 'mdl_',
//           'wd_host' => 'http://127.0.0.1:4444/wd/hub',
//           'behat_wwwroot' => 'http://127.0.0.1/moodle',
//           'behat_dataroot' => '/home/example/bht_moodledata'
//       ),
//   );
//
// To change name of behat parallel run site, define BEHAT_PARALLEL_SITE_NAME and parallel run sites will be suffixed
// with this value
// Example:
//   define('BEHAT_PARALLEL_SITE_NAME', 'behatparallelsite');
//
// Command line output for parallel behat install is limited to 80 chars, if you are installing more then 4 sites and
// want to expand output to more then 80 chars, then define BEHAT_MAX_CMD_LINE_OUTPUT
// Example:
//   define('BEHAT_MAX_CMD_LINE_OUTPUT', 120);
//
// Behat feature files will be distributed randomly between the processes by default. If you have timing file or want
// to create timing file then define BEHAT_FEATURE_TIMING_FILE with path to timing file. It will be updated for each
// run with latest time taken to execute feature.
// Example:
//   define('BEHAT_FEATURE_TIMING_FILE', '/PATH_TO_TIMING_FILE/timing.json');
//
// If you don't have timing file and want some stable distribution of features, then you can use step counts to
// distribute the features. You can generate step file by executing php admin/tool/behat/cli/util.php --updatesteps
// this will update step file which is defined by BEHAT_FEATURE_STEP_FILE.
// Example:
//   define('BEHAT_FEATURE_STEP_FILE', '/PATH_TO_FEATURE_STEP_COUNT_FILE/stepcount.json');
//
// Feature distribution for each process is displayed as histogram. you can disable it by setting
// BEHAT_DISABLE_HISTOGRAM
// Example:
//   define('BEHAT_DISABLE_HISTOGRAM', true);
//
// Mobile app Behat testing requires this option, pointing to a developer Moodle Mobile directory:
//   $CFG->behat_ionic_dirroot = '/where/I/keep/my/git/checkouts/moodlemobile2';
//
// The following option can be used to indicate a running Ionic server (otherwise Behat will start
// one automatically for each test run, which is convenient but takes ages):
//   $CFG->behat_ionic_wwwroot = 'http://localhost:8100';
//
//=========================================================================
// 12. DEVELOPER DATA GENERATOR
//=========================================================================
//
// The developer data generator tool is intended to be used only in development or testing sites and
// it's usage in production environments is not recommended; if it is used to create JMeter test plans
// is even less recommended as JMeter needs to log in as site course users. JMeter needs to know the
// users passwords but would be dangerous to have a default password as everybody would know it, which would
// be specially dangerouse if somebody uses this tool in a production site, so in order to prevent unintended
// uses of the tool and undesired accesses as well, is compulsory to set a password for the users
// generated by this tool, but only in case you want to generate a JMeter test. The value should be a string.
// Example:
//   $CFG->tool_generator_users_password = 'examplepassword';
//
//=========================================================================
// 13. SYSTEM PATHS (You need to set following, depending on your system)
//=========================================================================
// Ghostscript path.
// On most Linux installs, this can be left as '/usr/bin/gs'.
// On Windows it will be something like 'c:\gs\bin\gswin32c.exe' (make sure
// there are no spaces in the path - if necessary copy the files 'gswin32c.exe'
// and 'gsdll32.dll' to a new folder without a space in the path)
//      $CFG->pathtogs = '/usr/bin/gs';
//
// Path to PHP CLI.
// Probably something like /usr/bin/php. If you enter this, cron scripts can be
// executed from admin web interface.
$CFG->pathtophp = '/usr/local/bin/php';
//
// Path to du.
// Probably something like /usr/bin/du. If you enter this, pages that display
// directory contents will run much faster for directories with a lot of files.
$CFG->pathtodu = '/usr/bin/du';
//
// Path to aspell.
// To use spell-checking within the editor, you MUST have aspell 0.50 or later
// installed on your server, and you must specify the correct path to access the
// aspell binary. On Unix/Linux systems, this path is usually /usr/bin/aspell,
// but it might be something else.

// 14. ALTERNATIVE FILE SYSTEM SETTINGS
//=========================================================================
//
// Alternative file system.
// Since 3.3 it is possible to override file_storage and file_system API and use alternative storage systems (e.g. S3,
// Rackspace Cloud Files, Google Cloud Storage, Azure Storage, etc.).
// To set the alternative file storage system in config.php you can use the following setting, providing the
// alternative system class name that will be auto-loaded by file_storage API.
//
//      $CFG->alternative_file_system_class = '\\local_myfilestorage\\file_system';
